An 18-month-old boy, with complete immunization schedule to date, who consults the Emergency Department for right knee swelling after playing in the park, without obvious trauma. In the directed anamnesis, the mother refers that an uncle of hers had similar problems. The ultrasound examination is compatible with hemarthrosis and in the analytical analysis only an APTT lengthening of 52'' (normal 25-35'') stands out. What is the most probable diagnostic hypothesis?

"title": "Further evidence for recessive inheritance of von Willebrand disease with abnormal binding of von Willebrand factor to factor VIII.",
"score": 0.0185201063,
"content": "A new family with a bleeding diathesis and FVIII deficiency secondary to abnormal binding of von Willebrand factor (vWF) to factor VIII (FVIII) is described. Two propositi of this family, an 18-year-old male and a 33-year-old female, both with a history of epistaxis, bruising, bleeding from the gums, epistaxis, hemarthrosis, and hematoma, were analyzed. Also additional members of the same family with no bleeding history were also studied. The propositi showed normal vWF activities, low FVIII activity; one of them had been diagnosed as having hemophilia A and the other was a hemophilia A carrier. Both showed a very poor response to treatment with FVIII concentrates and desmopressin (DDAVP) but a good clinical response to cryoprecipitate. APTT was prolonged and no inhibitory activity was noticeable in their plasmas. Thirty-five units per kilogram body weight of Hemofil M was infused to both propositi and FVIII reached basal level within 60 minutes of the infusion. No FVIII response at all was observed in the female after intravenous DDAVP administration. However, the male who received the infusion of 35 U/kg body weight of Humate-P achieved a normal FVIII level that was maintained for 12 hours. Multimeric analysis of vWF was normal in all the members studied. Von Willebrand factor domain for FVIII binding was assayed in the two propositi and in six other members of the same family by using a non-isotopic and sensitive method, a modification of the one previously described, using the Hemofil M concentrate as exogenous FVIII. The data obtained showed that both propositi had similar binding to that observed by using plasma of a patient with severe von Willebrand disease. Furthermore, five siblings had a decreased binding of vWF to FVIII, when compared with plasma from normal individuals or patients with hemophilia A. We also observed that, for screening purpose, the ratio of bound FVIII/immobilized vWF (at saturation of the anti-vWF and offering of 1 U/ml of exogenous FVIII) distinguished two levels of abnormality (normal range 0.70-1.15, propositi 0.004-0.007, and remaining members affected 0.25-0.42). The most probable explanation is that the propositi are homozygous or double heterozygous, the other five siblings affected being heterozygous for a recessive vWF defect. This more accessible assay presented here may be of help in routine analysis for diagnosing this type of von Willebrand disease, which has important implications for therapy and genetic counseling."

"content": "To assess the frequency and characteristics of children with inherited bleeding disorders that were initially misdiagnosed, leading to inappropriate disease management. This study was conducted at the Haematology/Pathology Department of Fauji Foundation Hospital, Rawalpindi, Pakistan, from August 2014 to August 2018. Children who were diagnosed with an inherited bleeding disorder but did not respond to initial therapy were reevaluated. In total, 62 children were diagnosed with a bleeding disorder. Of these, 27 were diagnosed with an inherited bleeding disorder and 35 with an acquired bleeding disorder. Of the 27 children with inherited bleeding disorders, 18% (n = 5) were misdiagnosed and treated inappropriately. The median age of the misdiagnosed patients was 9 years (range, 5-13 years). Three patients with Bernard-Soulier syndrome had been misdiagnosed as having immune thrombocytopenic purpura, 1 patient with von Willebrand disease had been misdiagnosed as having hemophilia A, and 1 patient with haemophilia B had been misdiagnosed as having hemophilia A. There are chances of misdiagnosis and improper or invasive management if comprehensive laboratory evaluation and a thorough clinical evaluation are not performed in children with congenital bleeding disorders."

"title": "The dental patient with a congenital bleeding disorder.",
"score": 0.0173926195,
"content": "Congenital bleeding disorders account for approximately one in 10,000 births. Dentists are often anxious about delivering treatment to this special group of patients. In the Irish Republic, patients with inherited bleeding disorders have their dental care co-ordinated centrally at the National Centre for Hereditary Coagulation Disorders (NCHCD), St James's Hospital, Dublin. Dental care is normally integrated with routine outpatient haematological appointments. This ensures regular monitoring of oral health and the early treatment of any hard/soft tissue pathology. This article describes, in simple diagrammatic form, the normal coagulation mechanism (Figures 1 and 2), explains common coagulation terms (Appendix 1), and examines the three most common congenital bleeding disorders: haemophilia A, haemophilia B, and von Willebrand disease. General recommendations based on the current literature are provided with respect to procedures that are appropriate to perform in a general dental practice setting. Although not discussed in this article, it is important to note that non-coagulation bleeding disorders also exist. These include: hereditary haemorrhagic telangiectasia; blood vessel wall defects resulting from connective tissue disorders such as Marfan syndrome and Ehlers-Danlos syndrome; and, platelet disorders such as Bernard-Soulier syndrome, resulting in defective platelet adhesion."

"title": "Screening bleeding disorders in adolescents and young women with menorrhagia.",
"score": 0.0156178751,
"content": "Chronic menorrhagia causes anemia and impairment of life quality. In this study the aim was the screening of bleeding disorders in adolescents and young women with menorrhagia. The study was performed prospectively by pediatric hematologists. A form including demographic characteristics of the patients, bleedings other than menorrhagia, familial bleeding history, characteristics of the menorrhagia, and impairment of life quality due to menorrhagia was filled out by the researcher during a face-to-face interview with the patient. A pictorial blood assessment chart was also used for evaluation of blood loss. All patients underwent pelvic ultrasound sonography testing and women also received pelvic examination by gynecologists. Whole blood count, peripheral blood smear, blood group, serum transaminases, urea, creatinine, ferritin, PFA-100, PT, aPTT, INR, TT, fibrinogen, VWF:Ag, VWF:RCo, FVIII, and platelet aggregation assays were performed. Platelet aggregations were studied by lumiaggregometer. Out of 75 patients enrolled, 60 patients completed the study. The mean age was 20.68±10.34 (range: 10-48) years and 65% (n=39) of the patients were younger than 18 years. In 18 (46%) of the adolescents, menorrhagia subsided spontaneously. In 20% (n=12) of the patients, a bleeding disorder was detected (1 case of type 3 von Willebrand disease, 2 patients with low VWF:Ag, 1 case of probable von Willebrand disease, 3 cases of Bernard-Soulier syndrome, 2 cases of Glanzmann thrombasthenia, 2 cases of immune thrombocytopenic purpura, 1 case of congenital factor VII deficiency). In patients with menorrhagia, at least complete blood count, peripheral smear, aPTT, PT, VWF:Ag, VWF:RCo, FVIII, and fibrinogen assays must be performed. When there is history of nose and gum bleeding, platelet function assay by lumiaggregometer must also be performed. In nearly 50% of adolescents, menorrhagia is dysfunctional and transient. Detailed coagulation assays can be postponed in adolescents if bleeding history other than menorrhagia and/or family history of bleeding and/or parental consanguinity is absent. All subjects with menorrhagia must consult with gynecologists and hematologists. None declared."

"title": "Ehlers-Danlos syndrome, clotting disorders and muscular dystrophy.",
"score": 0.0155485674,
"content": "Ehlers-Danlos syndrome includes 11 distinct entities. The diversity of this collagen dysplasia and its combination with other abnormalities make it difficult to understand physiopathologically. A case of Ehlers-Danlos syndrome is reported, which is novel owing to its combination with clotting abnormalities and especially with muscular dystrophy. To our knowledge this has not previously been reported. The patient was a young man aged 16 years who presented with Ehlers-Danlos syndrome satisfying Perelman's diagnostic criteria. His father and two brothers had comparable clinical symptoms, but his mother and sister were healthy. The four male subjects had an increased cephalin-kaolin time, reduced levels of factor VIII and Willebrand's factor (but without haemophilia A or Willebrand's disease), and, especially, an abnormal platelet ATP secretion. The proband alone had muscular disease with bilateral quadriceps fatigability and amyotrophy. The muscle enzyme levels were greatly increased, the electromyographic trace was myogenic, and the biopsy showed severe muscular dystrophy. This new observation poses the problem of the relation between clotting abnormalities and collagen abnormalities in the Ehlers-Danlos syndrome. It is difficult to classify this case within any of the 11 known types because of its muscular manifestations. It may perhaps be a fortuitous combination or an extension of the nosological framework of this syndrome."

"score": 0.015040515,
"content": "Differential diagnosis The differential diagnosis for Bernard–Soulier syndrome includes both Glanzmann thrombasthenia and pediatric Von Willebrand disease. BSS platelets do not aggregate to ristocetin, and this defect is not corrected by the addition of normal plasma, distinguishing it from von Willebrand disease. Following is a table comparing its result with other platelet aggregation disorders: Treatment Bleeding events can be controlled by platelet transfusion. Most heterozygotes, with few exceptions, do not have a bleeding diathesis. BSS presents as a bleeding disorder due to the inability of platelets to bind and aggregate at sites of vascular endothelial injury. In the event of an individual with mucosal bleeding tranexamic acid can be given. The affected individual may need to avoid contact sports and medications such as aspirin, which can increase the possibility of bleeding. A potential complication is the possibility of the individual producing anti-platelet antibodies."

"content": "He published a Swedish-language article in 1926 about the disease, titled Hereditär pseudohemofili (\"Hereditary pseudohemophilia\"). He referenced six previous publications from the years of 1876 to 1922, totalling 19 cases on families with bleeding diatheses. The earlier authors attributed the condition to hemophilia (even in the cases of females) or to thrombopathy, which was discovered shortly before as the cause of what had previously been known as purpura hemorrhagica or Werlhof's disease. Von Willebrand also conducted hematological examinations on Hjördis and some of her family members. He recorded a normal or slightly reduced number of platelets and an undisturbed clot retraction, unlike Glanzmann's thrombasthenia. The bleeding time (Duke) was greatly prolonged, extending to more than 2 hours in some cases, while the clotting time was within the normal range. He concluded that the disease was either a new form of thrombopathy or a condition of the capillary endothelium."

"score": 0.0129261084,
"content": "Epistaxis, superficial and deep hematomas, hemarthrosis, gastrointestinal bleeding, hematuria represent the most frequent hemorrhagic events in congenital coagulation disorders. Occasionally, bleeding manifestations occur in unusual sites or are peculiar. A clotting defect may alter the clinical aspect of skin conditions or infections (hemorrhagic scabies or varicella). Hemobilia may occur as a complication of transjugular liver biopsy in hemophilia or Bernard-Soulier syndrome. Hemarthrosis of small joints of feet and hands occur in patients with hemophilia treated with protease inhibitors. Intramedullary hematomas of long bones have been described in α2-plasmin inhibitor or fibrinogen deficiencies. Spleen fracture with consequent hemoperitoneum has been reported in patients with fibrinogen deficiency. Rectus muscle sheath hematoma may occur in patients with factor VII (FVII)or FX deficiency. Acute or subacute intestinal obstruction may be caused by intramural wall hematomas in hemophilia and von Willebrand (vW)-disease. Physicians should always keep in mind that a congenital hemorrhagic disorder may cause bleeding in any tissue of the body and therefore alter the normal clinical features of a given disease."

"score": 0.0128478841,
"content": "The objective of the present study was to determine the pattern of inherited bleeding disorders in southern Iran and evaluate the effect of a comprehensive coagulation laboratory and related efforts. A total of 545 patients with inherited bleeding disorders were evaluated during 1992-2007 by a cross-sectional study. Data were collected by a data-gathering form. Statistical analysis was done using Statistical Package for the Social Sciences version 15. A P value less than 0.05 was considered statistically significant. Overall 411 patients had common bleeding disorders including 326 hemophilia A, 46 hemophilia B, and 39 von Willebrand disease. Seventy-nine patients had rare coagulation disorders including deficiency of factor VII (n = 26), factor X (n = 18), factor XIII (n = 9), factor I (n = 9), factor XI (n = 7), factor V (n = 4), combined factor VIII and factor V (n = 4), and combined factor X and factor VII (n = 2). Fifty-five patients had platelet disorders including 23 with Glanzmann's thrombasthenia, 15 with Bernard-Soulier syndrome, and 17 with other platelet disorders, most of which (45) were diagnosed after the establishment of the comprehensive coagulation laboratory. Annual mean number of new diagnosed patients with common and rare bleeding disorders increased from 29 +/- 4 to 38 +/- 17. The ratio of the patients diagnosed with rare bleeding disorders to common bleeding disorders significantly increased after the establishment of the comprehensive diagnosis laboratory (P < 0.001).It seems that implementation of collaborative projects by the Shiraz Hemophilia Society and the establishment of the comprehensive coagulation laboratory and treatment centers have been successful in increasing diagnosis of the inherited bleeding disorders and consequently better management of the patients."

Patients with a history of bleeding tendency were tested for confirmation of the diagnosis. History and clinical findings were recorded. Laboratory analysis included prothrombin time (PT), activated partial thromboplastin time (APTT), bleeding time (BT), and fibrinogen assay. Patients with prolonged APTT were tested for factors VIII (FVIII) and IX (FIX). If FVIII was low, von Willebrand factor: antigen (vWF:Ag) and von Willebrand factor:ristocetin cofactor (vWF:RCo) were performed. When PT and APTT both were prolonged, FV, FX, and FII were tested. Platelet aggregation studies were done when there was isolated prolonged BT. Urea clot solubility test was done when all coagulation tests were normal. All patients with hemophilia A and B were evaluated for inhibitors. Of the 376 patients, inherited bleeding disorder was diagnosed in 318 (85%) cases. Median age of patients was 16.4 years. Hemophilia A was the commonest inherited bleeding disorder that was observed in 140 (37.2%) followed by vWD 68 (18.0%), platelet function disorders 48 (12.8%), and hemophilia B in 33 (8.8%) cases. We also found rare congenital factor deficiencies in 13 (3.4%), low VWF in 11 (3.0%) participants and 5 (1.3%) in female hemophilia carriers. Hemarthrosis was the most frequent symptom in hemophilia A and B (79.7%) involving knee joint. Inhibitor was detected in 21 (15%) cases. Fresh frozen plasma/cryoprecipitate were the most common modality of treatment. In 58 patients, no abnormality was detected in coagulation profile. Hemophilia A and vWD are the most common congenital bleeding disorders in this study. Hemarthrosis involving knee joint was the most common complication.

Duke's method With the Duke;s method, the patient is pricked with a special needle or lancet, preferably on the earlobe or fingertip, after having been swabbed with alcohol. The prick is about 3–4 mm deep. The patient then wipes the blood every 30 seconds with a filter paper. The test ceases when bleeding ceases. The usual time is about 2–5 minutes. This method is not recommended and cannot be standardized because it can cause a large local hematoma. Interpretation Bleeding time is affected by platelet function, certain vascular disorders and von Willebrand Disease—not by other coagulation factors such as haemophilia.

"content": "Other conditions can also present similarly with bleeding after minor trauma or spontaneous bleeds and require exclusion before confirming the diagnosis of hemophilia. Some of these conditions include von Willebrand disease, scurvy, diseases of platelet dysfunction, deficiency of other coagulation factors like V, VII, X, or fibrinogen, Ehlers-Danlos syndrome, Fabry disease, disseminated intravascular coagulation, and child abuse. In von Willebrand disease, bleeding symptoms can be similar to mild hemophilia, but patients with von Willebrand disease have more mucosal bleeding compared to musculoskeletal bleeding seen in hemophilia. Von Willebrand disease is diagnosed by checking for von Willebrand factor antigen or von Willebrand factor multimers. [40] Similarly, in scurvy, Ehlers-Danlos syndrome, and Fabry disease; also, the bleeding is usually mucosal, unlike hemophilia, where it is musculoskeletal. In scurvy, there is a deficiency of vitamin C. [41] In Ehlers-Danlos syndrome, the skin is hyperextensible, and joints are hypermobile. The diagnosis is usually through clinical features, genetic testing, and tissue biopsy. [42] Similarly, in Fabry disease, patients may also have other organs being affected, including kidneys and heart, and have skin lesions called angiokeratomas. They also have pain in the extremities. Fabry disease is usually diagnosed with clinical findings and genetic testing. [43] In cases of platelet dysfunction disorders, bleeding is usually mucocutaneous, unlike hemophilia. Usually, these disorders are diagnosed by platelet aggregation studies or platelet electron microscopy. [44] In the deficiency of other coagulation factors, musculoskeletal bleeding is uncommon. In fact, sometimes thrombosis can occur, especially in patients with factor VII or fibrinogen deficiency or in patients with combined factor V and VIII deficiency. Specific coagulation factor assays usually confirm the diagnosis. Disseminated intravascular coagulation (DIC) that mimics hemophilia is hard to differentiate, but usually, there is an underlying condition in DIC, for example, acute promyelocytic leukemia. Diagnosis is usually carried out by blood tests that show decreased platelet count and the absence of factor VIII autoantibodies. Child abuse can sometimes be misidentified and confused with hemophilia, and it is essential to find inconsistencies in the history of how trauma has occurred. Other signs of malnourishment require vigilance, and x-rays may reveal evidence of fractures of different ages. [45] [46]"

Its utility was tested in a small study, including patients with known inherited platelet disorders. The study demonstrated a specificity of 100%, a positive predictive value of 90%, and a negative predictive value of 100% using this assessment tool. [17] In the setting of von Willebrand disease, a BAT score >6 repeatedly correlates to a 99% probability of an inherited platelet defect such as BSS. [8] ] Similarly, other bleeding assessment tools like Molecular and Clinical Markers for the Diagnosis and Management (MCMDM) of type 1 von Willebrand's disease (VWD) and the World Health Organization Bleeding Assessment Tool are similar tools. An electronic version of MCMDM-type-1 VWD was developed in 2010. [17]"

"content": "Hemophilia is a sex-linked recessive genetic disorder characterized by the absence or deficiency of factor VIII (hemophilia A, orclassic hemophilia) or factor IX (hemophilia B, or Christmas disease) (Chap. 141). Hemophilia A constitutes 85% of cases. Spontaneous hemarthrosis is a common problem with both types of hemophilia and can lead to a deforming arthritis. The frequency and severity of hemarthrosis are related to the degree of clotting factor deficiency. Hemarthrosis is not common in other disorders of coagulation such as von Willebrand disease, factor V deficiency, warfarin therapy, or thrombocytopenia. Hemarthrosis occurs after 1 year of age, when a child begins to walk 2241 and run. In order of frequency, the joints most commonly affected are theknees,ankles,elbows,shoulders,andhips.Smalljointsofthehands and feet are occasionally involved."

"content": "The authors report a case of hemarthrosis complicated by severe anemia related to a congenital connective tissue disease: Ehlers-Danlos syndrome. A boy fell down and suffered tumefaction of both knees with bilateral rupture of the rotula tendon. He underwent surgical reinsertion of each tendon on the rotula. He later showed an unexpected ongoing hematic effusion, with severe anemia. He was screened for coagulation disorders with no results. On taking a more detailed history and investigating the patient's phenotypical features, the authors diagnosed Ehlers-Danlos syndrome, hypermobile variant. The hemarthrosis and anemia were thus concluded to be consequences of excessive tissue fragility due to a congenital connective tissue disease."

"score": 0.0099009901,
"content": "Recurrent haemarthrosis is the final cause of haemophilic arthrosic disease in haemophilia patients. Therefore, it is essential to diagnose it early, both clinically and by imaging. In addition, haemophilia patients experience chronic synovitis, joint degeneration, muscle haematoma and pseudotumours. The objective of this article is to highlight the value of ultrasounds in the diagnosis and control of the evolution of musculo-skeletal problems in haemophilia patients. To this end, we have performed a literature search in the PubMed, Web of Science(®) (WOS) and SciVerse bases, using the following keywords: hemophilia or haemophilia and ultrasonography (US), ultrasound, echography and sonography. The search was limited to studies published in English between the years 1991 and 2011, finding a total of 221 references. After reviewing the title or abstract for evidence of the use of US for the diagnosis of musculo-skeletal lesions in haemophilia, we selected 24 of these references. We added data collected from our experience to the most important data found in the references. Our main conclusion is that US is highly valuable for the diagnosis of musculo-skeletal diseases in haemophilia. It is a fast, effective, safe, available, comparative, real-time technique that can help us confirm the clinical examination. It is particularly important in acute haemarthrosis, as it can be used to objectively identify the presence of blood in the joints, measure its size, pinpoint its location, assess its evolution and confirm its complete disappearance."

"content": "PURPOSE\\AIM: Hemophilia affects the blood clotting process, is a genetic disease characterized by recurrent bleeding. The hemophilia early arthropathy detection with ultrasound (HEAD-US) procedure and scoring method were designed for the detection of early changes in affected joints of patients. In this article, it was aimed to detect early arthropathic changes in the joints of hemophilia patients with the HEAD US scoring system and to investigate its clinical contribution. It was aimed to investigate the effectiveness of HEAD-US scoring in showing early joint damage in subclinical hemophilia cases and its contribution to treatment. The present study included 50 hemophilia patients who were admitted to Departments of Pediatric and Adult Hematology for routine follow-up. During routine follow-up controls, patients were scored by physical examination and HJHS 2.1 and by ultrasonography and HEAD US. Statistical tests were used to analyze joint health status and the results of US examination in the patient group. A total of 294 joints (elbow n = 100, knee n = 94, ankle n = 100) were evaluated by ultrasonography. The mean HJHS and HEAD-US scores of the patients were 14.94 ± 15.18 and 15.6 ± 12.6, respectively. HEAD-US is accepted to be more sensitive than HJHS in detecting early signs of arthropathy. Detection of early abnormalities by ultrasonography will enable the development of individualized treatment protocols and to the prevention of arthropathy development."

"content": "Von Willebrand's disease is the most common inherited bleeding disorder, with an overall prevalence in the general population of 0.8% to 1.3%. Hemarthrosis occurs mainly in the severest forms of the disease (type III), with a frequency of 3.5% to 11%, and can cause severe arthropathy similar to that seen in hemophilia. We retrospectively reviewed our experience with nonsurgical synovectomy in the treatment of recurrent hemarthrosis with arthropathy in patients with von Willebrand's disease. Four of our six patients had type III disease and the remaining two had type II disease. The age range was 13 to 63 years. The frequency of hemarthrosis prior to synovectomy was one to four per month. One (n = 2) or both (n = 1) knees were treated in 4 cases, one (n = 1) or both (n = 1) ankles in 3 cases and an elbow in one case. We used yttrium 90 in a dose of 5 mCi for one knee, rhenium 186 in a dose of 2 mCi for two ankles and the elbow and osmic acid for two knees and one ankle. Clinical and radiological results were evaluated six months after synovectomy using the World Federation of Hemophilia score. Radiologic lesions remained stable and clinical manifestations improved in every case (p < 0.05). Five patients achieved a complete remission. Safety was satisfactory. The clinical efficacy of synovectomy done, using radiocolloids or osmic acid in arthropathy due to von Willebrand's disease, seems similar to that in hemophilia."

"content": "Assessment of clinical outcome after joint bleeding is essential to identify joint damage and optimise treatment, to prevent disability. However, disease-specific tools to assess the musculoskeletal status in patients with von Willebrand disease (VWD) are lacking. We aimed to determine validity and reliability of the Haemophilia Joint Health Score (HJHS) and Haemophilia Activities List (HAL) in patients with Von Willebrand disease (VWD). Ninety-six patients with VWD were included (mean age 46 years) of whom 27 had more than five documented joint bleeds. The HJHS was performed in all patients and all patients completed the HAL and Impact on Participation and Autonomy (IPA) questionnaires. Health-related quality of life (SF36) results were obtained from the prior 'Willebrand in the Netherlands' study. Joint X-rays of knees, elbows and ankles were scored according to Pettersson (PS). Internal consistency of the HJHS (Cronbach's α (α)=0.75) and HAL (α=0.89) were good. Inter-observer agreement of the HJHS was good (ICC 0.84; Limits of Agreement ± 10.3). The HJHS showed acceptable correlation with the X-ray PS (Spearman's r (r<subs</sub)>0.60 all joints) and HAL (r<subs</sub=0.71). The HAL also showed acceptable correlation with the SF36 physical functioning (r<subs</sub=0.65) and IPA (r<subs</sub=0.69). Hypothesis testing showed adequate discriminative power of both instruments: in patients with a history of >5 versus ≤ 5 joint bleeds (median HJHS 10 vs 2 (p<0.01); median HAL 77 vs 98 (p<0.01)), independent from age. In conclusion, both the HJHS and HAL are feasible to assess clinical outcome after joint bleeds in VWD."

Patients with primary bleeding disorders from all the major provincial capitals of Pakistan were screened for ARBDs. Prothrombin (PT), activated partial thromboplastin time (APTT), bleeding time (BT) and fibrinogen levels were measured. Cases with isolated prolonged APTT were tested for factors VIII and IX using factor assays This was followed by FXI:C level assessment in cases with normal FVIII and FIX levels. vWD was screened in patients with low FVIII levels. Factors II, V and X were tested in patients with simultaneous prolongation of PT and APTT. Peripheral blood film examination and platelet aggregation studies were performed to assess platelet disorders. Urea clot solubility testing was done to detect Factor XIII levels where platelet function tests were normal. Descriptive analysis was done using SPSS version 16. Of the 429 suspected bleeding disorder patients, 148 (35%) were diagnosed with hemophilia A and 211 (49.1%) patients had ARBDs. 70 patients (16.3%) remained undiagnosed. Out of 211 patients with ARBD; 95 (33.8%) had vWD type 3. Fibrinogen deficiency was found in 34 patients (12%), GT in 27 (9.6%), factor XIII deficiency in 13 (4.6%), factor VII deficiency in 12 (4.3%), factor V deficiency in 9 (3.2%). Eight patients (2.8%) had vitamin K-dependent clotting factor deficiency, Bernard-Soulier syndrome was diagnosed in seven patients (2.5%), factor X deficiency in 2 (0.7%), factor II deficiency in 2 (0.7%), factor XI deficiency and combined factor V and VIII deficiency in 1 (0.4%) patient each. vWD type 3 was the most common ARBD found in our sample of patients in Pakistan, followed by fibrinogen deficiency and GT in respective order."

Regarding VWD limited studies are available in Pakistan. The current study was aimed to determine the clinical presentation and frequency of types of VWD. A cross sectional study was carried out from 16th December 2012 to 15th December 2013 on fifty one patients of VWD. Patients were diagnosed on the basis of prolonged bleeding time, abnormal APTT, reduced level of VWF: Ag, FVIII, VWF: RCo and ratio of VWF: RCo/VWF Ag. Among them 26 (50.98%) were male and 25 (49.02%) were female. Type3 VWD (94.12%) was found to be the commonest type. Two (3.92%) cases of type-2 VWD and only one (1.96%) case of type-1 VWD were identified. Easy bruising was the most commonly observed clinical presentation, 21 (41.18%) patients, followed by epistaxis 7 (13.73%), gum bleed 4(7.84%) menorrhagia 5(9.80%), haemarthosis 2(3.92%), haematoma formation 5 (9.80%), bleeding after circumcision 2 (3.92%), bleeding after surgery 2 (3.92%) and umbilical cord bleeding 3 (5.88%). Consanguineous marriages were reported in parents of 42 (82.4%) patients. Family history of bleeding disorder was reported in 44 (86.27%) of cases. Type-3 VWD was found to be the commonest type which can be attributed to the fact that type-3 VWD is transmitted through autosomal recessive pattern of inheritance and consanguineous marriages are highly practiced in our society leading to high frequency of this form of VWD. Easy bruising and epistaxis were concluded to be the most common clinical presentation. Menorrhagia was found to be common in the females of child bearing age."

"content": "The aim of this study is to evaluate the efficiency of a treatment prescribed, in the course of an hospital consultation for sleep pathology, to patients suffering from chronic insomnia not improved by longstanding and sustained medication with hypnotic drugs. The basis of the treatment is a progressive but total withdrawal of hypnotics in so far taken regularly. The withdrawal of hypnotics was prescribed to 79 patients: 33 aged 17 to 39 years (group 1, mean age 30) and 46 aged 40 to 70 years (group 2, mean age 51). 41 showed primary psychophysiological insomnia and 28 showed insomnia associated with psychiatric disorders. In patients of group 1, the average durations were 8 years for insomnia and 3 years for sustained hypnotic use; these durations were 15 and 5 years respectively in patients of group 2. Hypnotic drug withdrawal was achieved without placebos in 3 months in group 1 patients and 5 months in group 2 patients. 65 patients completely stopped the continual use of hypnotics. Subjective improvement of insomnia was reported by 51 of these patients (as well as by 6 patients who were given simultaneous antidepressant therapy). 16 of the 51 improved patients have resorted to hypnotics occasionally (at intervals of 10 days or more). After complete withdrawal, patients went on consulting for various lengths of time: 5 months average for group 1, 14 months average for group 2. This study of a fairly large group of insomniacs shows the frequent ineffectiveness of a sustained use of currently available hypnotics. It also shows that two times out of three the complete stop of sustained hypnotic medication proved beneficial to the patient."

Each GP recruited five insomniac subjects in the course of 1 week or 5 consecutive office days over a period of 2 weeks. On each office day, a brief questionnaire (Q1) including five questions investigating insomnia symptoms and current use of treatment was administered to the first 10 patients who referred to the GP office for reasons associated with their own health. The first patient of each day classified as insomniac underwent a second investigation based on a more detailed questionnaire (Q2) including demographic variables, socio-economic status, general medical conditions, severity, duration and clinical features of insomnia, daytime dysfunction, sleep satisfaction and therapeutic management. In a primary care setting, insomnia symptoms are often persistent (>1 year), recurrent (>1/week) and accompanied by daytime consequences. Two out of three patients with insomnia symptoms are dissatisfied with their sleep. In most cases, insomnia symptoms are underrated both by the patients, who cover the problem or reject treatment, and by the GP, who limits intervention on the sleep disorder (scarcely modifying ongoing therapy both in responders and in non-responders). In responders, treatment was confirmed in 91% of cases and discontinued in only 2%. When there was no improvement, or if insomnia symptoms became worse (non-responders), treatment was nevertheless continued in 74.5% of cases, either maintaining the same ineffective dose, increasing the dose, or adding another drug or a non-pharmacological procedure. Regardless of specific medication, the Italian GP privileges the pharmacological approach, which is fourfold more frequent than non-pharmacological therapy (78.6 versus 18.2%). Non-benzodiazepine hypnotic drugs are mostly prescribed when the GP decides to apply medication in previously untreated patients with insomnia symptoms. Self-administration is not unusual among the patients with insomnia symptoms and is more common among non-responders. Italian GPs tend to confirm the ongoing therapy and avoid re-evaluation of the treatment regimen. Limited use of non-pharmacological treatment in the Italian primary care setting is in line with this conservative approach of the GPs who tend to be problem-solvers rather than problem-seekers."

Perampanel is an antiepileptic also effective on the structure of sleep, and in restless legs syndrome. We describe the first study that evaluates perampanel in patients with chronic insomnia. Observational retrospective cohorts study of 66 patients with chronic resistant insomnia, 33 exposed to perampanel, other 33 as non-exposed group. All patients attended in Neurology or Psychiatry Consultation, from November 2017 to November 2018. Patients included had been treated with more than 4 different drugs in the previous 4 years. We reviewed age, sex, insomnia etiology, years of evolution, number of previously used drugs, and the results of perampanel for insomnia after 3 months of treatment in the exposed cohort, measured by the improvement of 3 or more points in the ISI and Pittsburgh scales, as well as the average of hours of sleep gained. Non-exposed patients were matched with this variables, but never treated with perampanel. We have included 66 patients. In the exposed cohort: we describe 33 patients with chronic resistant insomnia, 20 women (60 %), 13 men (40 %). Average age 53.48 years, average time of evolution: 11.25 years. Main etiology: depression 13 cases (40 %). After the combination of perampanel 2-4 mg (100 %) with antidepressants (17 cases, 51.5 %) or anxiolytics (12 cases, 36.36 %) along 3 months: the total number of hours of sleep improves in 2.5 h, the scale ISI improves by 6 points (± 2.1 SD, p = 0.02), and Pittsburgh scale improves in 4 points (± 1.7, p = 0.04). In non-exposed cohort, the improvement of the ISI scale was 2.2 points (±0.8, p = 0.06), on the Pittsburgh scale was 1.6 points (± 0.5, p = 0.01). The main adverse effect was irritability in 3 patients, without withdrawal perampanel. The treatment was abandoned by 4 patients (12.12%): 1 due to persistent irritability (3%), 2 due to lack of efficacy (6 %), 1 due to pregnancy wish (3 %). The combination of Perampanel with an antidepressant, or an anxiolytic, improves the quality of sleep measured by ISI and Pittsburgh scales (statistically significant), probably due to its antagonistic action on glutamate. A clinical trial compared with placebo would be necessary to corroborate these results."

All the patients of the present study were visited in our outpatients' department. Three hypnotic drugs were used for the treatment of insomnia: zolpidem, or triazolam, or oxazepam, respectively at doses of 10mg/day, 0.125-0.25mg/day and 15.0mg/day. All the three drugs showed to be effective and safe; no paradoxical effects were observed."

"content": "Sam is a 6-year-old boy with a diagnosis of autism spectrum disorder (ASD) who recently relocated and has an appointment with you, his new pediatric clinician, to establish care. He was previously followed by a psychiatrist for 2 years for additional diagnoses of insomnia, bipolar disorder, anxiety, attention deficit hyperactivity disorder, and intellectual disability. He has tried and (apparently) failed multiple psychotropic trials including stimulants, nonstimulants, mood stabilizers, atypical antipsychotics, and nonbenzodiazepine hypnotics. He has a delayed sleep onset and frequent night awakenings each night for the past 3 months, during which he \"screams, cries, and thrashes and can stay up for over an hour.\" His behaviors are described as irritable, self-injurious, and aggressive with no clear pattern of triggers according to his mother. He is nonverbal and communicates by leading and rarely pointing. The patient's current medication regimen includes clonidine 0.2 mg at night, lorazepam 1.5 mg as needed at night, olanzapine 5 mg twice daily, and diphenhydramine as needed for sleep/agitation. His mother is concerned that he is developing \"tolerance\" to the regimen and wants to wean him off some of the medications. His mother is struggling to take care of the patient given his worsening behavior and body habitus (body mass index >99%; z = 3.41).There is a family history of depression, anxiety, bipolar disorder, and autism. He has a 3-year-old sister, who is also diagnosed with ASD, though she is not as severely impacted. His mother's partner recently moved in along with 2 children of his own, aged 3 and 4 years. Sam attends a specialized school, where he receives behavior therapy and occupational therapy. He has undergone inpatient pediatric hospitalization twice, 1 time for 3 weeks and the other for 6 days, for aggressive behavior, and in both instances, he was discharged before inpatient psychiatric placement because of a lack of available beds.After urgent consultation with your local developmental and behavioral pediatrician, a slight reduction was made in the lorazepam because of concerns about tolerance and side effects. However, within a week of this, he was brought to the emergency department for continued self-injurious behavior and increased trouble with sleeping. His mother voiced concerns about his safety in the home, which were particularly related to aggression toward his younger sister. He was admitted to the pediatric inpatient floor for observation, and medication adjustment (increasing olanzapine), which was initially helpful in improving behavior, but mostly behavioral/environmental strategies were used to soothe him, including frequent wagon rides through the hospital corridors.Despite the patient being stable from the medical standpoint, Sam's mother did not feel comfortable taking him home. Social work contacted local community mental health services to pursue outpatient resources and respite care options and sought inpatient pediatric psychiatry. After several failed attempts to find placement, he remained in pediatric inpatient care for 1 and a half months with no acute medical interventions other than his oral medications.He was finally accepted to the in-state pediatric psychiatric facility when a bed was available. During his week-long stay, he had further medication adjustments with a decrease in olanzapine and optimization of his clonidine dose. During his psychiatric hospital stay, care coordination succeeded in arranging center-based applied behavior analysis interventions and respite care and parent training for his family. Sam began to show improvement in his overall agitation and aggression, requiring less clonazepam, and his mother then maintained outpatient follow-up.The day before discharge, you visit him in the hospital, and a medical student asks you why he was in the hospital for so long. How would you answer the question?"

Forty-eight psychiatrically ill patients (DSM-IV diagnoses) who had failed to respond to medicinal treatment for chronic insomnia were referred for and completed behavioral therapy as an adjunct to the pharmacologic treatment of their insomnia. The behavioral treatments included structured sleep hygiene, progressive muscle relaxation, stimulus control, and sleep restriction. The treatment program was accomplished in 6 sessions over 2 months. Follow-up evaluations were completed at 2, 6, and 12 months from the beginning of the treatment program. The outcome of the treatment program was evaluated in terms of the change in (1) self-reported specific sleep parameters, (2) self-ratings of sleep-related day-time state, (3) self-rating of quality of sleep, (4) the use of sleep medication, and (5) the therapist's global rating of improvement. There was a statistically significant change from the baseline in all self-reported specific sleep parameters after 2 months that was sustained after 6 and 12 months. Sleep-related characteristics of daytime state showed statistically significant changes after 2 and 6 months that were maintained after 12 months. Sleep quality had a statistically significant change after 2 months, continued to improve statistically after 6 months, and was maximum after 12 months. Over half the patients (52.7%; 20 of 38) either reduced their sleep medication by half or stopped it completely. The therapist's global rating showed an improvement in 29.2% (N = 14) of patients after 2 months, 56.2% (N = 27) after 6 months, and 68.7% (N = 33) after 12 months. The use of concomitant behavioral and pharmacologic treatment of chronic insomnia in psychiatrically ill patients results in improving sleep and sleep-related state and reduces the risk of return of insomnia for 10 months after finishing active treatment."

Two broad types of insomnia may often be distinguished: (1) difficulty falling asleep and frequent wakening, characteristic of anxiety states or obsessive worrying; and (2) early morning wakening, sometimes in a panic, suggestive of endogenous depression. The first group of patients respond well to minor tranquilizers and psychotherapy, whereas the second do well with tricyclic anti-depressants. Many studies in sleep laboratories have declineated the stages and cycles of sleep physiology and pathology, especially the importance of REM or dreaming sleep. The clinician should be cautious in the use of hypnotics like barbiturates which suppress REM sleep and produce a rebound increase on withdrawal, as well as problems of dependence of habituation. Flurazepam and chloral hydrate are considerably safer in this respect. Understanding sleep neurophysiology and biochemistry permits appropriate individual clinical management for both psychiatric patients and medical patients with conditions like peptic ulcer and nocturnal angina pectoris."

Although cognitive behavioral therapy for insomnia (CBT-I) is considered the standard of care [1], several monotherapies, including sleep restriction therapy, stimulus control therapy, and relaxation training are also recommended in the treatment of chronic insomnia [2]. CBT-I is a multimodal intervention comprised of a combination of behavioral (eg, sleep restriction, stimulus control) and cognitive therapy strategies, and psychoeducation delivered in 4 to 10 weekly or biweekly sessions [3]. Given that insomnia is thought to be maintained by an interaction between unhelpful sleep-related beliefs and behaviors, the goal of CBT-I is to modify the maladaptive cognitions (eg, worry about the consequences of poor sleep), behaviors (eg, extended time in bed), and arousal (ie, physiological and mental hyperarousal) perpetuating the insomnia. CBT-I is efficacious when implemented alone or in combination with a pharmacologic agent. However, because of the potential for relapse upon discontinuation, CBT-I should be extended throughout drug tapering [4]. Although the treatment options should be guided by the available evidence supporting both psychological therapies and short-term hypnotic treatment, as well as treatment feasibility and availability, treatment selection should ultimately be guided by patient preference [5]. Despite its widespread use among treatment providers [6], the use of sleep hygiene education as a primary intervention for insomnia should be avoided. Sleep hygiene may be a necessary, but insufficient condition for promoting good sleep and should be considered an adjunct to another empirically supported treatment."

"score": 0.0089285714,
"content": "Untreated insomnia often has repercussions on socio-professional or cognitive functioning of insomniacs. In industrialized countries, the prevalence of insomnia ranges between 10% and 48%, depending on the methodology and the measured time interval. However, few studies have examined the relationship between insomnia and mental disorder diagnoses. This epidemiological study on insomnia complaints was conducted on 5 622 subjects representative of the non-institutionalized French population aged 15 years or over. Sixteen interviewers using the Sleep-EVAL expert system performed telephone interviews. Insomnia complaints (defined as difficulty initiating or maintaining sleep, feeling unrefreshed at awakening accompanied by dissatisfaction with sleep quality or quantity, or use of sleep-promoting medication) were observed in 18.6% (95% confidence interval: 17.6% to 19.6%) of the sample. The median duration of insomnia complaints was five years. Regional variations in the prevalence of insomnia complaints were observed in France. In North 2 and Center 4 regions, the prevalence of insomnia complaints was higher compared to the rest of France with a relative risk of 1.4 (95% confidence interval: 1.1-1.6) time superior for the North region and 1.3 (95% CI: 1.0-1.6) for the Center 4 region. The lowest prevalence was registered in the Mediterranean area. In most regions, the prevalence of insomnia complaints was higher in women than in men with the exception of the South and West regions where the prevalence was similar. Subjects with insomnia complaints consulted more frequently compared to the rest of sample with an odds ratio of 3 to 1 [95% CI: 2.8 to 4.1]. Close to 20% of subjects were being treated for a physical disease at the time of the survey; subjects with insomnia complaints being twice more numerous (34.3%) than the rest of the sample (15.9%; p<0.001). To identify the main factors associated with insomnia complaints, socio-demographic and health variables were introduced in a multivariate model. Separated or divorced individuals (OR: 1.6); widowers (OR: 1.5); subjects aged between 45 and 65 years (OR: 1.4) or older than 65 (OR: 1.5); women (OR: 1.3); those with little or no education (OR: 1.4); and subjects living in the North region had higher reported insomnia complaints. Living in the East region (Mediterranean) was a protective factor (OR: 0.6). Furthermore, subjects with vascular diseases (OR: 2.0), musculo-skeletal diseases (OR: 2.0) or cardiac diseases (OR: 1.9) and those who had consulted a physician in the previous six months (OR: 2.7) had higher a probability of insomnia complaints. Subsequently, DSM IV insomnia diagnoses were examined in subjects who complained of insomnia. A diagnosis of primary insomnia was found in 7% of these subjects. A diagnosis of insomnia related to another mental disorder was found in 15.6% of insomnia complainers. A depressive disorder diagnosis was given in 10.8% of cases (mainly a major depressive disorder). This diagnosis was made more often among women and subjects of less than 65 years. An anxiety disorder diagnosis was given for 33.1% of insomnia complainers (an anxiety generalized disorder in about half the cases). About a quarter of insomnia complainers did not receive a diagnosis. This was the case more often for men and the subjects 65 years or older. If demographic and medical factors are relatively well documented at the epidemiological level, it is otherwise for psychiatric diagnosis associated with insomnia complaint. Very few studies in the general population have been done and still fewer of them have applied a positive and differential diagnosis process. In this study, we used the DSM IV classification to establish positive and differential diagnoses among subjects with insomnia complaints. Compared to other epidemiological studies, our study is distinguished by several aspects: 1) insomnia complaint had a narrower definition. It did not suffice that the subject reported insomnia symptoms, it was also necessary that the subject said s/he was dissatisfied with her/hr/his sleep or that s/he took measures to improve it (medication or sleep hygiene). This choice was motivated essentially by the fact that it is difficult, from a point of clinical point of view, to consider that an individual has insomnia solely based on the presence of symptoms, that, appreciated by a clinician, would resemble insomnia without that they make problem for the subject. 2) Several sleep habits were systematically collected. The majority of epidemiological studies are not centered on sleep problems, with the consequence that results do not allow a global view of factors that are associated with insomnia. 3) The various diagnostic categories of insomnia as well as elements of the differential diagnosis were applied. Thus, we can conclude that insomnia, as a diagnostic entity, including all its forms, is found in 5.6% of the French population. In the majority of cases, the insomnia complaint is part of the symptomatology of a mental disorder, mainly an anxiety disorder. This distinction is important since it helps the physician to determine therapeutic choices. To conclude, it is worthwhile to consider the number of insomnia complainers who had consulted a physician, mainly a general practitioner, in the six months prior to the study. This designates physicians as the first-line resource in the treatment and the prevention of sleep disorders."

One hundred eighty-two drug-naive patients with PD derived from a population-based incident cohort and 202 control participants were assessed for insomnia before treatment initiation and were repeatedly examined after 1, 3, and 5 years. Insomnia was diagnosed according to the Stavanger Sleepiness Questionnaire. The Parkinson's Disease Sleep Scale was used to differentiate sleep initiation problems from problems of sleep maintenance. Generalized estimating equation models were applied for statistical measures. The prevalence of insomnia in general was not higher in patients with PD compared to controls at the 5-year follow-up. There were changes in the prevalence of the different insomnia subtypes over the 5-year follow-up. The prevalence of solitary problems in sleep maintenance increased from 31% (n = 18) in the drug-naive patients at baseline to 49% (n = 29) after 1 year and were associated with the use of dopamine agonists and higher Montgomery-Åsberg Depression Rating Scale scores. The prevalence of solitary sleep initiation problems decreased continuously from 21% (n = 12) at baseline to 7.4% (n = 4) after 5 years; these were associated with less daytime sleepiness. The prevalence rates of the different insomnia subtypes changed notably in patients with early PD. The frequency of sleep maintenance problems increased, and these problems were associated with dopamine agonist use and depressive symptoms, while the total number of patients with insomnia remained stable. Our findings reflect the need for early individual assessments of insomnia subtypes and raise the possibility of intervention to reduce these symptoms in patients with early PD."

A 65-year-old woman consults for weakness in the right hand that has spread in a few months to other muscle territories of both arms and legs, with distal predominance. On examination there is atrophy and fasciculations in different metameric territories with preserved sensitivity. There is a bilateral Babinski's sign, what is the diagnostic test that would confirm the suspected diagnosis?

"score": 0.0168617614,
"content": "A 64-year-old man was admitted to our department because of muscle cramp, atrophy and weakness of the limbs together with difficulty in walking, which had gradually progressed from age 60. About 1 year prior to admission, he had noticed hand tremor and gynecomastia. On admission, neurological examination revealed diffuse muscle atrophy and weakness of the extremities, which were more obvious on the right side with preponderance in the right leg. Bilateral postural hand tremor was also more prominent on the right hand. Fasciculations were observed both in the extremities and tongue. The remaining cranial nerves and cerebellar functions were intact. Sensation was normal except for slightly decreased vibratory sense in the distal part of the legs. Deep tendon reflexes including jaw jerk were increased with the exception of hyporeflexia of the right leg. Babinski sign was negative bilaterally. Blood examination disclosed slight elevation of CK and fasting glucose level of 110 mg/dl. Glucose tolerance test showed a diabetic pattern. CSF examination showed total protein of 74 mg/dl and IgG of 12 mg/dl. On a series of endocrinological studies, there was no significant elevation of androgen and estrogen both in serum and urine except for slight elevation of serum E1 level. Serum LH and FSH, however, were markedly high, which responded far beyond the normal range following to 0.1 mg injection of LH-RH. These results suggested that gynecomastia might be caused by dysfunction of the hypothalamus-hypophysis system. Brain CT and spine MRI showed no abnormality. Muscle biopsy obtained from the right quadriceps femoris revealed neurogenic abnormalities.(ABSTRACT TRUNCATED AT 250 WORDS)"

"content": "Signs and symptoms As a result of lower motor neuron degeneration, the symptoms of PMA include: muscle weakness muscle atrophy fasciculations Some patients have symptoms restricted only to the arms or legs (or in some cases just one of either). These cases are referred to as flail limb (either flail arm or flail leg) and are associated with a better prognosis. Diagnosis PMA is a diagnosis of exclusion, there is no specific test which can conclusively establish whether a patient has the condition. Instead, a number of other possibilities have to be ruled out, such as multifocal motor neuropathy or spinal muscular atrophy. Tests used in the diagnostic process include MRI, clinical examination, and EMG. EMG tests in patients who do have PMA usually show denervation (neuron death) in most affected body parts, and in some unaffected parts too. It typically takes longer to be diagnosed with PMA than ALS, an average of 20 months for PMA vs 15 months in ALS."

"score": 0.0153067163,
"content": "A 57-year-old man developed severe muscle weakness and atrophy of the upper extremities within a five-month period. Neurological examination revealed severe weakness and atrophy in the scapular muscles and proximal and distal muscles of the upper extremities. Fasciculations were also observed in the various muscles of the upper extremities. There was neither muscle weakness, atrophy nor fasciculation in either his face, neck muscles or lower extremities. He had no pseudobulbar or bulbar signs. Tendon reflexes were mildly hyperactive in the jaw and lower extremities, and normal in the upper extremities. There were no pathological reflexes, spasticity or sensory disturbances. The needle EMG study revealed denervation potentials in all muscles of the upper extremities examined. The nerve conduction study revealed no findings of the conduction block. Cervical spine X-rays revealed the narrowing of the spinal foramens at the left C3/C4 and bilateral C4/C5, C5/C6, and C6/C7 intervertebral levels. In addition, magnetic resonance imaging (MRI) revealed compressions of the cervical cord at C4/C5 and C5/C6 intervertebral levels. These clinical and neuroradiological findings resembled those of the cervical spondylotic amyotrophy (CSA). However, the motor evoked potential (MEP) study revealed the pyramidal tract dysfunction above the levels of the pyramidal decussation. Furthermore, brain MRI revealed abnormal foci in both internal capsules which were characterized by hyperintense relative to cortical gray matter on T2-weighted images and still hyperintense to white matter on proton-density-weighted images. In addition, T2-weighted images demonstrated a low signal within the motor cortex and hyperintense lesions in the white matter of the precentral gyri. These MRI findings indicated the degeneration of the pyramidal tract and corresponded to those found in the patients with amyotrophic lateral sclerosis (ALS) which have been recently reported. It has been difficult to distinguish ALS from CSA. However, MEP and brain MRI studies were useful for distinguishing these two diseases in this patient. In addition, this patient showed typical MRI findings suggesting the degeneration of the pyramidal tract, although this patient had a relatively short course of illness and did not show obvious physical findings suggesting pyramidal tract dysfunction."

"score": 0.0152201891,
"content": "We report an 80-year-old woman with progressive muscular atrophy predominantly involving her right lower extremity. She was well until 1992 (75 years of age) when she noted an onset of weakness in her right leg which had got progressively worse. She was admitted to our service in July 1994. On admission, general physical examination was unremarkable. She was alert and well oriented without dementia. Higher cerebral functions were normal. Cranial nerves also appeared intact. She dragged her right leg in walking. Mild to moderate weakness (2/5 to 4/5) was noted in muscles in her right lower extremity more in the distal part. Deep tendon reflexes were within normal limits, and the plantar response was flexor bilaterally. Sensation was intact. Laboratory examinations were also unremarkable except for slight increase in CK which was 470 IU/l. CSF was also normal. EMG revealed neurogenic changes in the lower extremities. She was admitted to Aoki Hospital on October 21, 1994, by that time, her weakness in the right lower extremity had gotten worse in that the muscle strength of the right extensor hallucis longus was 0 and tibialis anterior 2; muscle atrophy was also prominent in her right leg; the right ankle jerk could not be elicited. In the subsequent course, weakness and atrophy appeared in her left lower extremity, however, upper extremities and cranial nerves had never been affected. Babinski sign was always negative. In February 1996, she developed delusional ideation of self persecution, and showed difficulty in communication with medical staffs. She developed fever of 38.7 degrees C on June 13, 1996 expired on the next day. The patient was discussed in a neurological CPC, and the chief discussant arrived at the conclusion that the patient had a form of spinal muscular atrophy. Opinions were divided between ALS and spinal muscular atrophy. Post-mortem examination revealed marked loss of anterior horn neurons in the lumbar area with astrogliosis. Bunina bodies were seen in some of the remaining neurons. No myelin pallor was noted in the pyramidal tracts, however, atrophy and loss of Betz cells were noted in the motor cortex. Other cortical areas were unremarkable. The neuropathologist arrived at the conclusion that the patient had ALS. This patient was unique in that she had asymmetric atrophy and weakness limited to the lower extremities. This is quite unusual as ALS of four years duration. In addition, the patient developed some mental change which was thought to represent dementia by some participants. But no clear morphologic changes were seen to account for her mental change."

"score": 0.015148248,
"content": "A 70 year old woman had suffered from diabetes mellitus type 2 since she was 52. Three years before the surgery she had begun to experience weakness together with altered sensitivity in the right leg, which was regarded as having been caused by diabetic polyneuropathy. During the admission examination the level for algesia on the right-hand side was at about D 11, a distal paraparesis of the leg (3-4 degrees, Janda's classification), more intense on the right, hyperactive deep tendon reflexes, Babinski's reflex on both sides, and depressed abdominal cutaneous reflexes. The sensitivity to vibrations on the Malleolus medialis on both sides was 0/8. The patient could walk only with the help of a Rollator. Over the three-year period following onset of symptoms the following tests were carried out: motor nerve conduction speeds of the N. tibialis and N. peronaeus, electromyogram of the N. tibialis anterior and the M. gastrocnemius, somatosensory evoked potentials (SSEP) of the N. tibialis, which indicated a lesion in the peripheral nerves or nerve roots. Cranial computed tomography (CCT), CT scan of the lumbar spine (L3-S1) and angiological investigation elicited no significant pathological findings. An MRI of the thoracal spine showed a vertebra-sized dorsal tumor pressing on the spinal cord from left to right. By means of microsurgery the spinal tumor was completely removed. Suspected meningeoma was confirmed by histological analysis. During the post-surgical period, the incomplete paraplegia quickly regressed, and 7 weeks after the removal of the spinal meningeoma the patient was able to climb stairs. In case of slowly-developing paresis of the legs in diabetic patients, diabetic polyneuropathy should not be diagnosed without careful consideration, and rare spinal tumors should be considered as part of the differential diagnosis, especially if the blood glucose level is normal, and intensive physiotherapy brings no improvement in the patient's condition."

"content": "Familial spastic paraplegia (FSP) with severe muscular atrophy of hands and feet is exceptional. Autosomal dominant forms were initially described by Silver in 1966. We report two cases, from the same Tunisian family, presenting FSP with severe amyotrophy of the hands. A brother and his sister, aged respectively 37 and 36 years old, presented practically the same clinical picture. Their parents were cousins. The female patient was hospitalized. Both patients developed gait disorders around the age of three years. Muscular atrophy of the hands arose much later, around the age of 20 years. The neurological examination disclosed a spastic gait with distal amyotrophy, severe in the hands and moderate in the feet. Sensitivity was preserved and there was no fasciculation. The spinal cord and cerebral MRI was normal. Electromyography (EMG) showed a neurogenic pattern in the distal muscles. Stimulation of the median, ulnar and sciatica nerves was ineffective. The somatosensory evoked potentials (EP) were delayed (upper limb) or desynchronised (lower limb). The auditory and visual EP were normal. The cerebrospinal fluid contained 1 mononuclear cell/mm3 and 10 mg protein/100 ml. Abnormalities of the cranio-vertebral junction, Arnold-Chiari malformation, syringomyelia and familial juvenile amyotrophic lateral sclerosis (ALS) were excluded and the diagnosis of Silver's syndrome was evoked."

"content": "We report a patient with motor neuron syndrome similar to amyotrophic lateral sclerosis (ALS) and with spontaneous recovery. At the age 40, the woman developed progressive muscular weakness, atrophy and fasciculation in extremities. She also noted a dyspnea, tongue atrophy and dysphagia. A neurological examination 6 months after onset revealed i) a tongue atrophy and fasciculation, ii) diffuse muscule weakness and atrophy in face, neck and extremities, and iii) marked hyperreflexia in the four limbs and bilateral Babinski reflex, but iv) neither sensory disturbance nor ophthalmoplegia. Electromyogram (EMG) detected such denervation potentials as fibrillation potentials, fasciculation potentials, positive sharp waves and polyphasic or giant MUPs diffusely in the limb muscles. Peripheral nerve conduction study detected neither conduction block nor delay. Thus, she was diagnosed as suffering from ALS. However, since approximate 1 year after onset, her muscle weakness has gradually been getting better. Simultaneously, the dyspnea and dysphagia gradually improved. Two years after onset, an EMG examination detected chronic denervation potentials in the left musculus sternocleidomastoideus and a few on-going denervation potentials in the left musculus extensor carpi radialis, but no denervation potentials in other limb muscles. Fasciculation potentials were found in tongue muscles. Thus, the present case was thought to have a reversible motor neuron syndrome clinically quite similar to ALS. A mild increase in IgE (346 U/ml) and a low-titer IgM-class anti-GM1 antibody were found in her serum though its pathological significance was uncertain. Any immunological aberrance may account for the pathogenesis. It should be noted that clinically diagnosed cases of ALS may rarely recover spontaneously."

"content": "Corticobasal degeneration (CBD) is an uncommon, sporadic, neurodegenerative disorder of mid- to late-adult life. We describe a further example of the pathologic heterogeneity of this condition. A 71-year-old woman initially presented dysarthria, clumsiness, progressive asymmetric bradykinesia, and rigidity in left arm. Rigidity gradually involved ipsilateral leg; postural instability with falls, blepharospasm, and dysphagia subsequently developed. She has been previously diagnosed as unresponsive Parkinson's Disease. At our clinical examination, she presented left upper-arm-fixed-dystonia, spasticity in left lower limb and pyramidal signs (Babinski and Hoffmann). Brain MRI showed asymmetric cortical atrophy in the right frontotemporal cortex. Neuropsychological examination showed an impairment in visuospatial functioning, frontal-executive dysfunction, and hemineglect. This case demonstrates that association of asymmetrical focal cortical and subcortical features remains the clinical hallmark of this condition. There are no absolute markers for the clinical diagnosis that is complicated by the variability of presentation involving also cognitive symptoms that are reviewed in the paper. Despite the difficulty of diagnosing CBD, somatosensory evoked potentials, motor evoked potentials, long latency reflexes, and correlations between results on electroencephalography (EEG) and electromyography (EMG) provide further support for a CBD diagnosis. These techniques are also used to identify neurophysiological correlates of the neurological signs of the disease."

Somatosensory evoked potentials may be a useful adjunct to the conventional nerve conduction and EMG studies (Yiannikas and Walsh). Brachial artery MR angiography is usually reserved for patients with a suspected arterial occlusion, an aneurysm, or an obvious cervical rib.

The hand or forearm muscles may undergo atrophy; in a few cases, the atrophy of hand muscles is severe. In such cases, the spondylotic compression, as judged by MRI or CT myelography, may be confined to the high cervical cord, well above the levels of the motor neurons that innervate these muscles. In patients with sensory loss, pain and thermal sensation often appear to be affected more than tactile sense. An unexpected Babinski sign has already been mentioned and a few fasciculations may be seen, especially in proximal arm muscles. Another unusual feature in advanced stages of cervical cord compression is the appearance of mirror movements of the hands, in which effortful attempts to make refined movements of the fingers of one hand, causes the opposite hand to move similarly."

Long-continued disuse of one limb may lead to atrophy, but it is usually of lesser degree than atrophy caused by lower motor neuron disease (denervation atrophy). In disuse atrophy, the tendon reflexes are retained and nerve conduction studies are normal. With denervation of muscles, there may be visible fasciculations and reduced or abolished tendon reflexes in addition to paralysis. The location of the lesion (in nerves, spinal roots, or spinal cord) can usually be determined by the pattern of weakness, by the associated neurologic symptoms and signs, and by special tests—MRI of the spine, examination of the cerebrospinal fluid (CSF), and electrical studies of nerve and muscle. If the limb is partially denervated, the EMG shows reduced numbers of motor unit potentials (often of large size) as well as fasciculations and fibrillations."

We investigated the sensitivity, specificity and predictive values of various manoeuvres in order to determine the most sensitive and reliable test or combination thereof. Straight arm raising (Barré), pronator drift, Mingazzini's manoeuvre, finger tap, forearm roll, segmental strength and deep tendon reflexes were tested in 170 patients with (86) and without (84) a proven lesion in the motor areas confirmed by computed tomography. Segmental motor strength bad good specificity (97.5%) but poor sensitivity (38.9%) and negative predictive value (NPV) (58.7%). The forearm roll had a similar profile. Finger tap had a sensitivity of 73.3% and a specificity of 87.5%. Barré and pronator testing had a sensitivity and specificity of 92.2% and 90.0% respectively. Hyperreflexia had a sensitivity of 68.9% and a specificity of 87.5%. An abnormality of pronator, reflexes or finger tap had a sensitivity of 97%, and when these three tests were positive, specificity was 97%. When all six tests were positive, the positive predictive value was 100%, when all six tests were negative the NPV was 100%. The detailed segmental examination has very good specificity for detecting motor deficits, but the sensitivity and NPV are unacceptably low. Pronator drift with finger tap and reflexes is the most reliable and time-effective combination of tests for the detection of subtle motor lesions, and could replace the segmental motor examination as a screening for motor lesions."

"score": 0.0098039216,
"content": "Hirayama's disease (HD), is a benign, self-limited, motor neuron disease, characterized by asymmetric weakness and atrophy of one or both distal upper extremities. In the present study we report the clinical, electrophysiological and MRI features of a group of Italian patients, with review of the literature. Moreover we propose an optimized MRI protocol for patients with suspected or diagnosed HD in order to make an early diagnosis and a standardized follow up. Eight patients with clinical suspicion of Hirayama disease underwent evaluation between January 2007 and November 2013. All patients underwent standard nerve conduction studies (NCS), electromyography (EMG) and motor/sensory evoked potentials (MEP/SEP). Cervical spine MRI studies were conducted with a 1.5 Tesla MRI scanner in neutral and flexion position, including sagittal T1-weighted sequences and sagittal and axial T2-weighted sequences. The following diagnostic features were evaluated: abnormal cervical curvature, localized cervical cord atrophy in the lower tract (C4-C7), presence of cord flattening (CF), intramedullary signal hyperintensity on T2 weighted sequences, anterior shifting of the posterior wall of the cervical dural sac (ASD) and presence of flow voids (EFV) in the posterior epidural space during flexion. All patients complained of weakness in hand muscles as initial symptoms, associated with hand tremor in three of them and abnormal sweating of the hand palm in two of them. No sensory deficits and weakness at lower limbs were reported by any patients. Distal deep tendon reflexes at upper limbs were absent in all patients with the absence of the right tricipital reflex in one of them. Deep tendon reflexes at lower limbs were normal and no signs of pyramidal tract involvement were present. The clinical involvement at onset was unilateral in six patients (three left-sided and three right-sided) and bilateral asymmetric in two of them, with the right side more affected. With the progression of the disease all patients but one experienced weakness and wasting of hand muscles and forearm bilaterally, but still asymmetric. The duration of the progression phase of the disease ranged from eight months to three years. In all patients, NCS and EMG findings were consistent with a spinal metameric disorder involving the C7-T1 myotomes bilaterally; sensory conduction and electrophysiologic features at lower limbs were normal. MEP and SEP were normal and we did not observe the disappearance of the spinal potential during the neck flexion in any of the patients. MRI is the best diagnostic tool in the diagnosis of HD; it can confirm clinical diagnosis and exclude other conditions responsible for the neurological deficits leading to a correct patient management and therapy, limiting arm impairment. On MRI all patients had loss of the normal cervical lordosis (100%). Five patients had loss of attachment of posterior dural sac and anterior dural shift on flexion MRI with presence of flow voids from venous plexus congestion (62.5%); three patients had no anterior dislocation of the dural sac and no epidural vein congestion. Two patients showed localized cord atrophy, one at C5-C6 and the other at C6-C7 level (25%). Three patients had T2 intramedullary hyperintensities (37.5%) and cord flattening (CF) was present in 5 patients of 8 (62.5%). HD is a rare entity and a self-limited condition, but it has to be early differentiated from other diseases that may determine myelopathy and amyotrophy to establish a correct therapy and limit arm impairment. MRI is very important to confirm the clinical suspect of HD and a standardized MRI protocol using axial and sagittal images in both neutral and flexing position is needed, in order to diagnose and follow up affected patients."

We report the two year study of a woman who over the previous ten years had had three episodes of paraesthesia, with pins and needles in her left leg and other parts of the left side of her body, although never affecting head or neck. She also complained of tiring more than usual. In an outpatient clinic she was found to have a syndrome affecting the upper segments of the spinal cord, mainly involving the right side and resembling an incomplete Brown Sequard type syndrome. There were increased clinical muscle and deep reflexes. The most marked was that of the right deltoid (C5), bilateral fanning of the toes when the Babinski reflex was tested, Barré positive in the right leg, pins and needles and dysaesthesia on the left to an undetermined level. Function was well preserved when compared with the clinical signs found. The case was considered to be of monotopical MS. Spinal magnetic resonance findings confirmed the clinical diagnosis. We emphasise the value of careful clinical investigation directed towards the diagnosis of probable MS. We draw attention to the diagnostic value of the dissociation between the severe clinical alterations and the functional performance, which was surprisingly well maintained. Also we report the originality of the presence of bilateral fanning sign supporting the diagnosis of MS, occurring in a disease of adult life."

The patient had an insidious onset of weakness in his lower extremities at age 14, in that he noted a difficulty in standing up from a chair. Soon after he noted some difficulty in climbing up stairs. At age 35, he noted weakness in his arms; his weakness slowly progressed in that he became unable to walk or stand alone before 40 years of age. He also noted gynecomastia at that age. He was admitted to our hospital for the work up on September 16, 1993, when he was 54-year-old. On admission, he was alert and oriented; his BP was 150/70 mmHg; he had bilateral gynecomastia, however, no other skeletal deformities were found. On neurologic examination, he was mentally sound without dementia, and his higher cerebral functions were normal. Cranial nerves also appeared intact without facial atrophy, dysarthria, or dysphagia; no atrophy was noted in the tongue. He had marked muscle atrophy in both upper and lower extremities more marked in the proximal portions; muscle strength was approximately in the range of 2/5 to 3/5 in the proximal parts, and 4/5 in the distal parts in both upper and lower extremities. No fasciculation was noted; muscle tone was flaccid; no ataxia was present. Deep reflexes were either lost or markedly diminished. No Babinski sign was noted. Sensation was intact. Laboratory examination revealed normal blood counts; serum CK was slightly increased to 131 IU/l; ECG showed complete right bundle branch block; EMG revealed no active units in the right biceps brachii, deltoid, quadriceps femoris, and triceps surae muscles; in other muscles tested, motor unit potentials of low amplitude and short duration were seen; in the right tibialis anterior muscle, however, motor unit potentials with an amplitude up to 6 m V were also seen. Nerve conduction velocities were normal. A diagnostic procedure was performed. He was discussed in the neurological CPC, and the chief discussant arrived at the conclusion that this patient had Becker type of progressive muscular dystrophy. In her differential diagnosis, the possibility of Kennedy-Alter-Sung syndrome was discussed because this patient had gynecomastia. However, the discussant excluded that possibility because of absence of both bulbar symptoms and typical neurogenic changes in his EMG. The diagnostic procedure was a muscle biopsy on the left tibialis anterior muscle. Histologic observation on HE stained specimens revealed marked inequality in the muscle fiber diameters, increase in endomysial nuclei, proliferation of connective tissue, and fiber splitting.(ABSTRACT TRUNCATED AT 400 WORDS)"

Cerebrospinal fluid protein level was elevated to 3.4 g/L. Demyelinating neuropathy was predominantly in the proximal segment of the nerves. Low amplitude of CMAPs was recorded hardly over the vastus medialis and rectus femoris muscles, while weakness and atrophy in these muscles were not. The patient was refractory to treatment. He died three years after disease onset. <bConclusion:</bWe described a new clinical-electrophysiological phenomenon, which was characterized as a decrease in the evoked electrical excitability at the femoral nerve stimulation site (decreased CMAP), while the natural physiological conduction of the impulse from the motor neuron to the muscle was not blocked (preserved muscle strength)."

"score": 0.0096153846,
"content": "This is a single-center retrospective study. The objective of this study was to study the clinical symptoms and electrophysiological features of C6-7 myelopathy. This study was conducted at the Department of Orthopedic surgery, Yamaguchi University Graduate school of medicine, Japan. A total of 20 patients with cervical compressive myelopathy were determined by spinal cord-evoked potentials or a single level of obvious magnetic resonance imaging (MRI)-documented cervical spinal cord compression. Neurological examinations included manual muscle testing and investigation of deep tendon reflex, including Hoffmann sign, and of sensory disturbance areas. Motor-evoked potentials (MEPs), compound muscle action potentials (CMAPs) and F-wave were recorded from bilateral abductor digit minim and abductor halluces muscles. Central motor conduction time was calculated as follows: MEPs latency-(CMAPs latency+F latency-1)/2 (ms). Eighteen patients (90%) had negative Hoffmann sign. Eight patients (40%) had no sensory disturbance in the upper limbs and 8 patients (40%) had no muscle weakness in the upper limbs. We determined that patients had cervical myelopathy when their central motor conduction time measured in abductor digit minim was longer than 6.76 ms (+2 s.d.). Using this definition, the sensitivity for myelopathy was 42.8%. Patients with C6-7 myelopathy may lack clinical symptoms in their hands and central motor conduction time measured in abductor digit minim tended to be less prolonged, and it only showed symptoms in their lower limbs as gait disturbance. Surgeons should bear in mind the possibility of disorders of caudal C6-7 when they encounter patients with no or few symptoms in their hands and with leg weakness or numbness."

The patient was well until 59 years of age (January of 1986) when she noted bilateral ptosis. One year later, she noted a gradual onset of difficulty in speech (articulation). Her speech slowly deteriorated and she noted weakness in chewing power and difficulty in swallowing in addition. In October 1987, she developed emotional incontinence. In January of 1988, she started to drag her left foot. She was admitted to our hospital on June 13 of 1988. On admission, she was alert and general physical examination was unremarkable. Neurologic examination revealed no dementia; her higher cerebral functions appeared intact. Ptosis was present bilaterally more on the right. She showed difficulty in opening her eyes on command; no contraction of the frontal muscles was seen upon attempted eye opening. There was a moderate limitation in the vertical gaze. Forced laughing and crying were seen. Facial muscles were moderately weak without apparent atrophy. The movement of the soft palate was very weak, and swallowing disturbance was more prominent for liquid staff. The tongue appeared somewhat small, however, no fasciculation was noted. Her step was small and the posture was stooped. Retropulsion was present, however, Romberg's sign was absent. No muscle atrophy was apparent, however, diffuse mile to moderate muscle weakness was noted in all four limbs. Cerebellar sign was absent. Deep tendon reflexes were exaggerated bilaterally, and Babinski sign was present on the left side. Sensation was intact. Routine blood tests were unremarkable as was a cranial CT scan. Her ptosis did not improve after 10 mg of edrophonium injection. CSF was also normal. She was transferred to another hospital but her neurological disabilities further progressed. In 1989, she was totally unable to move her limbs; she could only move her eyes; still consciousness was clear without dementia. She developed respiratory difficulty and expired on July 25, 1992. She was discussed in a neurological CPC, and the opinions were divided into ALS and primary lateral sclerosis (PLS). The chief discussant arrived at the conclusion that the patient might have had the pyramidal form of ALS. Postmorten examination revealed marked myelin pallor in the anterior as well as lateral corticospinal tracts. Pyramidal tract degeneration was prominent starting at the level of the cerebral peduncle and was continued to be seen until the level of lumbar cord. The number of anterior horn cells showed only slight decrease in the cervical level, however, it was normal in the lumbar cord.(ABSTRACT TRUNCATED AT 400 WORDS)"

"content": "The particular value of clinical, radiological and electromyographical features is compared in 42 patients with motor deficit related to cervicarthrosic myelopathy or amyotrophic lateral sclerosis. The initial onset of the disease was identical (motor deficit and long tracts pathways involvement). Three different groups were identifyed according to the evolution: -- Group I: (13 cases): true lateral amyotrophic sclerosis which were not operated on. -- Group II (10 cases): myelopathy called \"cervicarthrosic\" because of radiological findings which were operated on but had the same steady worsened course as a lateral amyotrophic sclerosis. -- Group III (19 cases): cervical myelopathy which had surgery. The operation brought about stabilization or fairly good recovery over the 18 months following at least. From a clinical aspect, the \"Lhermitte sign\" or objective sensitive deficit are strongly significant for cervical myelopathy. On the contrary, diffuse fasciculations specially in the tongue seem to be mostly found in lateral amyotrophic sclerosis, whereas they are restricted into the paralysed area in cervical myelopathy. Electromyographic examination is decisive: simple activity with high frequency motor units (increased amplitude and polyphasic waves) or \"preponderant potentials\" into a cranial nerve territory or three segments of the lower limbs are frequently found in lateral amyotrophic sclerosis. These electromyographic features are less significant in the upper limbs. The neuroradiological findings lonely cannot assert definitely the cervicarthrosic origin of the myelopathy but visualize the conflicting situation between the spinal cord and the cervical canal and allow to choose the surgical procedure."

Fifty-three patients (29 men and 24 women), referred for electrodiagnostic testing, were positive for at least one of four clinical criteria for CR: abnormal (1) history, (2) motor (myotomal) examination, (3) sensory (dermatomal) examination, and (4) changes in deep tendon reflexes (DTR). All underwent electrodiagnostic assessment, needle electrode examination (NEE), specialized segmental reflexes (heteronymous and Hoffman's reflexes [H reflexes]), and neuroimaging. The clinical diagnosis was supported in all 32 patients who entered the study with two or more clinical signs for CR. Abnormal NEE was found in 90% of subjects with three clinical signs, 59% with two signs, and only 10% of those with one sign. H reflexes demonstrated a sensitivity of 72% and specificity of 85% for detection of CR and were particularly helpful when forming conclusions in the 21 subjects with only one clinical sign for CR. Specialized segmental H-reflex studies of the upper limb were as sensitive and specific as neuroimaging (magnetic resonance imaging)."

The patient was well until 15 years of the age when she noted that the ring finger of her left hand at times flexed when she did not intend to do so. She noted weakness in her left upper extremity at the age of 40, and difficulty in relaxing her hand grip at 45. She had an onset of tremor in her right foot at age 50, which was followed by difficulty in gait and hand writing. She was admitted to Juntendo University Urayasu Hospital when she was 63-year-old. Her mother, two sisters, and a son were affected with similar muscle weakness and myotonia. Although some of them developed stooped posture in the late stage of the disease, none of them had overt parkinsonism. General physical examination was unremarkable. Neurologic examination revealed an alert and oriented woman with some recent memory loss. She had bilateral ptosis, facial weakness, and a masked face. Myerson's sign was present. Her speech was small and monotonous. The sternocleidomastoid muscles were markedly atrophic and weak. The remaining of the cranial nerves were intact. She walked in small steps with freezing with support. She showed bradykinesia, retropulsion, and resting tremor in her right leg. Slight distal dominant weakness was noted in both upper and lower extremities more on the left. No cerebellar signs were noted. Muscle stretch reflexes were within normal limits in the upper extremities and diminished in the lower limbs. Sensation was intact. Routine laboratory findings were unremarkable. Cranial CT scan and MRI revealed slight cortical atrophy and leukoaraiosis. She responded to levodopa and she became able to walk by herself. She was transferred to another hospital one month after her admission. She had several bouts of airway obstruction with one episode of respiratory arrest. She expired six month after the transfer. The patient was discussed in a neurological CPC, and the chief discussant arrived at the conclusion that this patient suffered from myotonic dystrophy and Parkinson's disease which set in later years. Postmortem examination on the iliopsoas muscle revealed uneven muscle fiber diameters, central nuclei, and type 1 fiber predominance; the pathologic finding was consistent with myotonic dystrophy. The substantia nigra showed marked cell loss and Lewy bodies in the remaining neurons. The finding was consistent with Parkinson's disease. In myelin stain, diffuse myelin pallor was noted in the cerebral white matter which was the pathologic substrate of leukoaraiosis in this patient. Combination of these two disorders have never been reported in the literature to our knowledge. It appears to be that the coincidence is just a by-chance phenomenon, but it seems interesting to note that accelerated aging process appears to be present in both myotonic dystrophy and Parkinson's disease."

"score": 0.0093457944,
"content": "A 22-year-old female noted a low grade fever and swelling of the cervical lymph nodes in May 1997, and later developed a dry cough. She was diagnosed to have interstitial pneumonitis, and then administration of corticosteroids alleviated her symptoms. On February 6, 1998, however, a high fever recurred and her swollen cervical lymph node on the right side was biopsied on February 9, 1998. A histological examination revealed an increased number of histiocytes and karyorrhexis of the lymphocytes in the paracortical areas, and she was therefore diagnosed to have histiocytic necrotizing lymphadenitis. She could not fully elevate her arm on February 16, 1998. On admission, her cervical lymph node was swollen on the left side. A neurological examination revealed a marked weakness of the right deltoid muscle, moderate weakness of the right latissimus dorsi, triceps and brachioradialis muscles and also a mild weakness of the serratus anterior, supra- and infra-spinatus, and biceps brachii muscles. The muscle power of the other muscles were normal and no muscle atrophy was evident. Winging of the right scapula was observed. The deep tendon reflexes were normal in all four limbs, and her sensation was also normal. No cerebellar sign was found. The Jackson, Spurling, Allen, Morley and Adson tests were all negative. ESR was mildly elevated to 18 mm/hr, but CRP was negative. RF, ANA and anti-SS-A and SS-B antibodies were positive, whereas LE-test, direct and indirect Coombs tests and other autoantibodies were negative. Needle EMG disclosed fasciculation potentials in the right triceps muscle and polyphasic waves in the right deltoid muscle. MRI showed gadolinium-enhancement of the right brachial plexus. Although an abnormal accumulation of gallium was detected in the right parotid and bilateral submandibular glands, no sicca symptoms were found and the Schirmer test findings were normal. Oral prednisolone (50 mg/day with gradual tapering) alleviated both her symptoms and the gadolinium-enhancement of the right brachial plexus. As a result, her right upper limb paresis was thus considered to have been caused by right brachial plexus neuritis, which was probably associated with histocytic necrotizing lymphadentis. Although acute cerebellar ataxia and meningitis have previously been reported to be complicated with histiocytic necrotizing lymphadenitis, this is the first report to describe the complication of peripheral neuritis with this condition."

He was well until June of 1985 when he was 59-years-old when he had an acute onset of loss of vision in his right eye. He was treated by prednisolone with a complete remission. In August of 1986, he had another bout of blurring of vision in his left eye. Once he lost his left vision completely, from which he showed slow recovery. In January of 1987, he developed blurring of his right eye and loss of pain and touch sensation in his right leg. Since then he repeated loss of vision in his right or left eye five times, and he was admitted to our hospital in May of 1990. On admission, he was alert and oriented. General physical examination was unremarkable. Neurologic examination revealed bilateral optic nerve atrophy. He could not discriminate light or dark by either eye. Other cranial nerves were unremarkable. He could walk in a wide-base only with support; spasticity was noted in his left leg. Muscle strength was preserved. Deep reflexes were exaggerated in both legs with extensor plantar reflex bilaterally. Pain and touch sensation was decreased in the left leg by 30%, and vibration was diminished in both feet. Position sense was preserved. Routine blood counts and chemistries were unremarkable. Cranial MRI scans revealed multiple high-signal intensity lesions in both pontine bases, basal ganglia, thalami, and in the deep cerebral white matters. He was treated with oral prednisolone, plasmapheresis, lymphocytapheresis, and then immuran. His vision showed only slight recovery to discriminate light and dark. In October of 1990, slight weakness appeared in his both legs. In December of that year, he developed nausea, and a fiber colonoscopic study revealed a stenosis in the transverse colon. In March of 1991, he developed anemia and liver dysfunction. In July of that year, jaundice appeared, and his serum bilirubin was increased. In October, his leg weakness became more prominent, and his cranial CT scans at that time revealed a low density change in the right cerebellum in the right superior cerebellar artery territory; in addition, multiple low density spots were scattered to be seen in both cerebral hemispheres including the basal ganglia and thalamic areas with ventricular dilatation and cortical atrophy.(ABSTRACT TRUNCATED AT 400 WORDS)"

There were no sensory impairment and amyotrophy was observed in only one case. This picture suggested the diagnosis of motor neuron disease (MND). However, neurophysiologic examination demonstrated the presence of multifocal conduction blocks (CB) of the motor axons which were preferentially located in the proximal nerve segments and always at points atypical to nerve compression. The peripheral sensitive conductions and the somatosensory evoked potentials were normal, even through the nerve segments where the CB were located. Since this is a treatable potentially reversible syndrome, this motor neuropathy with CB should be included in the differential diagnosis of MND."

"content": "Spinal muscular atrophy (SMA) is an autosomal recessive anterior horn cell disease that results in progressive muscular weakness and atrophy without sensory involvement. A wide clinical spectrum that ranges from early death to essentially normal adult live exists. We describe a case of two 12 years olds, who represent two of three surviving non-identical quadruplets, born at 25 weeks gestational age. A diagnosis of hypotonic cerebral palsy (CP) was made in early childhood and early intervention services were initiated. At 3 years of age, MRI's showed white matter changes. Both briefly attained Gross Motor Functional Classification Scale (GMFCS) 3 status, but by 12 years of age their ambulatory abilities had decreased to Level 4. Physical Medicine and Rehabilitation (PM&R) physicians were consulted. On exam, distal lower extremities atrophy, hypotonia, hyporeflexia, and muscle weakness were noted. Neither child had upper motor neuron signs or spasticity. Cognition was normal. Neuromuscular disorder was suspected and genetic testing confirmed spinal muscular atrophy in both patients. While prior MRI/CT demonstrated static encephalopathy, recognition of symptoms and signs consistent with neuromuscular disease should have led to a secondary diagnosis. Therapeutic and surgical treatment decisions may have differed. Fragmentation of care and lack of a comprehensive team approach also contributed to the delay in recognition of their dual diagnosis."

This test is usually performed in the lower limbs and is valuable when on bedside one is not sure about the nature of hemiparesis. A subject with hemiparesis of organic cause while asked to flex the hip of normal leg against resistance will not exert pressure on the hand of examiner placed under the heel on the affected side while in hysterical weakness heightened pressure will be felt on the examiner's hand. The presumed genesis of this sign could be the crossed extensor reflex or the principle of synergistic contraction. It is a useful clinical test in differentiating functional and organic paresis with moderate sensitivity (63%) and high specificity (100%), but there are some limitations which should be kept in mind while evaluating a patient.

Acute ischemic stroke remains a medical emergency even during the COVID-19 pandemic. Here we present a case of a patient with COVID-19 who presented with acute ischemic stroke in the absence of common risk factors for cerebrovascular accidents. A 70-year-old male patient, with no prior comorbidities, presented to the emergency department (ED) with fever, cough, and shortness of breath for four days, and altered level of consciousness and right-sided weakness with the sensory loss for one day. On examination, the patient had a score of 8/15 on the Glasgow coma scale (GCS). There was a right-sided sensory loss and weakness in both upper and lower limbs with a positive Babinski's sign. The pulmonary examination was remarkable for bilateral crepitation. On blood workup, there was leukocytosis and raised c-reactive protein (CRP). D-dimer, ferritin, thyroid-stimulating hormone (TSH), vitamin B12, and hypercoagulability workup were normal. Transthoracic echocardiography was also normal. COVID-19 polymerase chain reaction (PCR) detected the virus. Chest x-ray showed infiltrations in the left middle and both lower zones of the lungs in the peripheral distribution. Computed tomography (CT) scan of the chest showed peripheral and mid to basal predominant multilobar ground-glass opacities. CT scan of the head showed a large hypodense area, with a loss of gray and white matter differentiation, in the left middle cerebral artery territory. Magnetic resonance imaging (MRI) of the head showed abnormal signal intensity area in the left parietal region. It appeared isointense on T1 image and hyperintense on T2 image. It also showed diffusion restriction on the diffusion-weighted 1 (DW1) image with corresponding low signals on the apparent diffusion coefficient (ADC) map. These findings were consistent with left middle cerebral artery territory infarct due to COVID-19. The patient was intubated in the ED. He was deemed unfit for thrombolysis and started on aspirin, anti-coagulation, and other supportive measures. Patients with COVID-19 should be evaluated early for neurological signs. Timely workup and interventions should be performed in any patient suspected of having a stroke to reduce morbidity and mortality."

"score": 0.0090909091,
"content": "To test a new neurological sign, the \"abductor sign,\" which can distinguish between organic and non-organic leg paresis using synergic movements of the bilateral hip abductors. The subjects were 33 patients presenting with paresis of one leg, 17 of organic origin and 16 of non-organic origin (hysteria). To test the abductor sign, the examiner told the patient to abduct each leg, and opposed this movement with his hands placed on the lateral surfaces of the patient's legs. The leg contralateral to the abducted one showed opposite actions for organic paresis and non-organic paresis: for example, when the paretic leg was abducted, the sound leg stayed fixed in organic paresis, but moved in the hyperadducting direction in non-organic paresis. Hoover's sign was used for comparison in the same patients. The abductor sign gave the correct classification for all 33 cases. Hoover's sign was reliable if the results were carefully interpreted, but it was non-diagnostic for 16 patients because of strong hip extensors and in two because of strong hip flexors. Two patients with non-organic paresis succeeded in tricking the examiner by pretending full effort to lift the paretic leg. The abductor sign is a useful test to detect non-organic paresis, because (1) it is difficult for a hysterical patient to deceive the examiner, (2) the hip abductor is one of the most commonly involved muscles in pyramidal weakness, and (3) the results are easily visible as movement or non-movement of the unabducted leg."

Four months before the presentation, he experienced bilateral foot paresthesias. Examination revealed weakness of the abductor digiti minimi, hallux extension weakness, and postural tremor bilaterally. He had hypersensitivity to pinprick in both hands with ulnar and median distribution. Sensory examination in the legs was normal. He had a postural tremor in both hands, which worsened on neck flexion. Spinal fluid analysis, including oligoclonal band testing, was normal. Electromyography demonstrated bilateral chronic C7 and C8 radiculopathies. Laboratory tests were normal. Flexion-extension magnetic resonance imaging demonstrated laxity of the dura and ligamentum flavum, with compression of cervical cord, maximal at C5-C6 in neck flexion. Laxity of the posterior dura during neck flexion has been postulated to lead to asymmetric lower cervical cord atrophy. Involvement of all 4 limbs is rare, and the condition can be mistaken for progressive multiple sclerosis."

We describe a patient with limb-onset ALS who developed vocal cord paralysis. A 74-year-old Japanese male consulted our clinic with a 6-month history of weakness in both arms. His family history was unremarkable. There were fasciculations and mild atrophy of the tongue and both arms. In the legs, muscle strength was almost normal but widespread fasciculations were present. All tendon reflexes were hypoactive and pathological reflexes were absent. Thereafter, he developed weakness of the legs and showed increased eating time. Babinski sign was positive bilaterally at this stage. The forced vital capacity dropped from 90% at the initial evaluation to 62% of the predicted value 14 months later. Two years after disease onset, the patient developed aspiration pneumonia with hoarseness and had difficulty clearing his throat of phlegm. Laryngoscopy demonstrated severe vocal cord paresis on both sides, particularly in the abductor muscles possibly leading to obstruction. Tracheotomy was performed because of the risk that the patient could choke to death. A review of the literature suggests that severe impairment of vocal cord abduction could be a prelude to sudden death in ALS. Follow up by laryngoscopic examination is necessary."
