Blood Pressure High Pressures Hypertension

Persistently high systemic arterial BLOOD PRESSURE. Based on multiple readings (BLOOD PRESSURE DETERMINATION), hypertension is currently defined as when SYSTOLIC PRESSURE is consistently greater than 140 mm Hg or when DIASTOLIC PRESSURE is consistently 90 mm Hg or more.


Despite the increasing need to identify and quantify tissue oxygenation at the cellular level, relatively few methods have been available. In this study, we developed a new hypoxia-responsive reporter vector using a hypoxia-responsive element of the 5' vascular endothelial growth factor untranslated region and generated a novel hypoxia-sensing transgenic rat. We then applied this animal model to the detection of tubulointerstitial hypoxia in the diseased kidney. With this model, we were able to identify diffuse cortical hypoxia in the puromycin aminonucleoside-induced nephrotic syndrome and focal and segmental hypoxia in the remnant kidney model. Expression of the hypoxia-responsive transgene increased throughout the observation period, reaching 2.2-fold at 2 weeks in the puromycin aminonucleoside model and 2.6-fold at 4 weeks in the remnant kidney model, whereas that of vascular endothelial growth factor showed a mild decrease, reflecting distinct behaviors of the two genes. The degree of hypoxia showed a positive correlation with microscopic tubulointerstitial injury in both models. Finally, we identified the localization of proliferating cell nuclear antigen-positive, ED-1-positive, and terminal dUTP nick-end labeled-positive cells in the hypoxic cortical area in the remnant kidney model. We propose here a possible pathological tie between chronic tubulointerstitial hypoxia and progressive glomerular diseases.

Disorders that are characterized by the production of antibodies that react with host tissues or immune effector cells that are autoreactive to endogenous peptides.


A chronic multi-system disorder of CONNECTIVE TISSUE. It is characterized by SCLEROSIS in the SKIN, the LUNGS, the HEART, the GASTROINTESTINAL TRACT, the KIDNEYS, and the MUSCULOSKELETAL SYSTEM. Other important features include diseased small BLOOD VESSELS and AUTOANTIBODIES. The disorder is named for its most prominent feature (hard skin), and classified into subsets by the extent of skin thickening: LIMITED SCLERODERMA and DIFFUSE SCLERODERMA.


Disseminated Sclerosis MS (Multiple Sclerosis) Multiple Acute Fulminating

An autoimmune disorder mainly affecting young adults and characterized by destruction of myelin in the central nervous system. Pathologic findings include multiple sharply demarcated areas of demyelination throughout the white matter of the central nervous system. Clinical manifestations include visual loss, extra-ocular movement disorders, paresthesias, loss of sensation, weakness, dysarthria, spasticity, ataxia, and bladder dysfunction. The usual pattern is one of recurrent attacks followed by partial recovery (see MULTIPLE SCLEROSIS, RELAPSING-REMITTING), but acute fulminating and chronic progressive forms (see MULTIPLE SCLEROSIS, CHRONIC PROGRESSIVE) also occur. (Adams et al., Principles of Neurology, 6th ed, p903)


Autologous haematopoietic stem cell transplantation is now a feasible and effective treatment for selected patients with severe autoimmune diseases. Worldwide, over 650 patients have been transplanted in the context of phase I and II clinical trials. The results are encouraging enough to begin randomised phase III trials. However, as predicted, significant transplant-related morbidity and mortality have been observed. This is primarily due to complications related to either the stage of the disease at transplant or due to infections. The number of deaths related to cardiac toxicity is low. However, caution is required when cyclophosphamide or anthracyclines such as mitoxantrone are used in patients with a possible underlying heart damage, for example, systemic sclerosis patients. In November 2002, a meeting was held in Florence, bringing together a number of experts in various fields, including rheumatology, cardiology, neurology, pharmacology and transplantation medicine. The object of the meeting was to analyse existing data, both published or available, in the European Group for Blood and Marrow Transplantation autoimmune disease database, and to propose a safe approach to such patients. A full cardiological assessment before and during the transplant emerged as the major recommendation.

Arteritis induced in rats by vasodilators, fenoldopam and theophylline, was examined immunohistochemically for expressions of inducible type of nitric oxide synthase (iNOS), basic fibroblast growth factor (bFGF) and tumor growth factor-beta1 (TGF-beta1). Rats were administered fenoldopam for 24 hours by intravenous infusion with or without following repeated daily oral administrations of theophylline. Irrespective of theophylline administration, iNOS antigens were remarkably abundant in ED-1-positive cells on day 5 and 8 post-fenoldopam-infusion (DPI); bFGF antigens were remarkably abundant in ED-1-positive cells on 1 and 3 DPI; TGF-beta1 antigens were observed in ED-1-positive cells on and after 5 DPI. These results suggest that the peak expression of iNOS antigen was followed by that of bFGF antigen, and bFGF may have a suppressive effect on iNOS expression in these rat arteritis models. On the other hand, TGF-beta1 was not considered to have a suppressive effect on iNOS expression in these models.


Low-molecular-weight heparin for the treatment of patients with mechanical heart valves.

Heparin Low Molecular Weight Low-Molecular-Weight LMWH

Heparin fractions with a molecular weight usually between 4000 and 6000 kD. These low-molecular-weight fractions are effective antithrombotic agents. Their administration reduces the risk of hemorrhage, they have a longer half-life, and their platelet interactions are reduced in comparison to unfractionated heparin. They also provide an effective prophylaxis against postoperative major pulmonary embolism.


BACKGROUND: The interruption of oral anticoagulant (OAC) administration is sometimes indicated in patients with mechanical heart valves, mainly before noncardiac surgery, non-surgical interventions, and pregnancy. Unfractionated heparin (UH) is currently the substitute for selected patients. Low-molecular-weight heparin (LMWH) offers theoretical advantages over UH, but is not currently considered in clinical guidelines as an alternative to UH in patients with prosthetic valves. HYPOTHESIS: The aim of the present study was to review the data accumulated so far on the use of LMWH in this patient population and to discuss its applicability in common practice. METHODS: For this paper, the current medical literature on LMWH in patients with mechanical heart valves was extensively reviewed. RESULTS: There were eight series and six case reports. None of the studies was randomized, and only one was prospective. Data to establish the thromboembolic risk were incomplete. After excluding case reports, the following groups were constructed: (a) short-term administration, after valve insertion (n = 212); (b) short-term, perioperative (noncardiac)/periprocedural (n = 114); (c) long-term, due to intolerance to OAC (n = 16); (d) long-term, in pregnancy (n = 10). The incidence rate of thromboembolism was 0.9% for all the studies and 0.5, 0, 20, and 0% in groups a, b, c, and d, respectively; for hemorrhage, the overall rate was 3.4% (3.8, 2.6, 10, and 0% for the respective groups). CONCLUSIONS: In patients with mechanical heart valves, short-term LMWH therapy compares favorably with UH. Data on mid- and long-term LMWH administration in these patients are sparse. Further randomized studies are needed to confirm the safety and precise indications for the use of LMWH in patients with mechanical heart valves.

2,3-4,5-bis-O-(1-methylethylidene)-beta-D-fructopyranose sulfamate Epitomax McN 4853 McN-4853 Topamax USL255 topiramate


Topiramate is a recently developed antiepileptic medication that is becoming more widely prescribed because of its efficacy in treating refractory seizures. Urologists should be aware that this medication can cause metabolic acidosis in patients secondary to inhibition of carbonic anhydrase. In addition, a distal tubular acidification defect may result, thus impairing the normal compensatory drop in urine pH. These factors can lead to the development of calcium phosphate nephrolithiasis. We report the first two cases of topiramate-induced nephrolithiasis in the urologic literature.

Hypokalemia Hypokalemias Hypopotassemia Hypopotassemias

Abnormally low potassium concentration in the blood. It may result from potassium loss by renal secretion or by the gastrointestinal route, as by vomiting or diarrhea. It may be manifested clinically by neuromuscular disorders ranging from weakness to paralysis, by electrocardiographic abnormalities (depression of the T wave and elevation of the U wave), by renal disease, and by gastrointestinal disorders. (Dorland, 27th ed)


OBJECTIVE: Nephrotoxicity is the major adverse effect of amphotericin B (AmB), often limiting administration of full dosage. Selective distal tubular epithelial toxicity seems to be responsible for the profound potassium wasting that is a major clinical side effect of treatment with AmB. Potassium depletion also potentiates the tubular toxicity of AmB. This study was designed to assess the ability of spironolactone to reduce potassium requirements and to prevent hypokalemia in neutropenic patients on AmB treatment. METHODS: In this study 26 patients with various hematological disorders were randomized to receive either intravenous AmB alone or AmB and oral spironolactone 100 mg twice daily when developing a proven or suspected fungal infection. RESULTS: Patients receiving concomitant AmB and spironolactone had significantly higher plasma potassium levels than those receiving AmB alone (P = 0.0027). Those patients receiving AmB and spironolactone required significantly less potassium supplementation to maintain their plasma potassium within the normal range (P = 0.022). Moreover, urinary potassium losses were significantly less in patients receiving AmB and spironolactone than those receiving AmB alone (P = 0.040). CONCLUSION: This study showed that spironolactone can reduce potassium requirements and prevent hypokalemia by reducing urinary potassium loss in neutropenic patients on AmB treatment.

Dopamine D2 receptor signaling controls neuronal cell death induced by muscarinic and glutamatergic drugs.

3,4 Dihydroxyphenethylamine 3,4-Dihydroxyphenethylamine 4-(2-Aminoethyl)-1,2-benzenediol Dopamine Hydrochloride Hydroxytyramine Intropin

One of the catecholamine NEUROTRANSMITTERS in the brain. It is derived from TYROSINE and is the precursor to NOREPINEPHRINE and EPINEPHRINE. Dopamine is a major transmitter in the extrapyramidal system of the brain, and important in regulating movement. A family of receptors (RECEPTORS, DOPAMINE) mediate its action.


Dopamine (DA), through D1/D2 receptor-mediated signaling, plays a major role in the control of epileptic seizures arising in the limbic system. Excitotoxicity leading to neuronal cell death in the affected areas is a major consequence of seizures at the cellular level. In this respect, little is known about the role of DA receptors in the occurrence of epilepsy-induced neuronal cell death. Here we analyze the occurrence of seizures and neurotoxicity in D2R -/- mice treated with the cholinergic agonist pilocarpine. We compared these results with those previously obtained with kainic acid (KA), a potent glutamate agonist. Importantly, D2R -/- mice develop seizures at doses of both drugs that are not epileptogenic for WT littermates and show greater neurotoxicity. However, pilocarpine-induced seizures result in a more widespread neuronal death in both WT and D2R -/- brains in comparison to KA. Thus, the absence of D2R lowers the threshold for seizures induced by both glutamate and acetylcholine. Moreover, the dopaminergic control of epilepsy-induced neurodegeneration seems to be mediated by distinct interactions of D2R signaling with these two neurotransmitters.

Hyperprolactinaemia Hyperprolactinemia Hyperprolactinemias Hypersecretion Syndrome Prolactin Inappropriate Secretion

Increased levels of PROLACTIN in the BLOOD, which may be associated with AMENORRHEA and GALACTORRHEA. Relatively common etiologies include PROLACTINOMA, medication effect, KIDNEY FAILURE, granulomatous diseases of the PITUITARY GLAND, and disorders which interfere with the hypothalamic inhibition of prolactin release. Ectopic (non-pituitary) production of prolactin may also occur. (From Joynt, Clinical Neurology, 1992, Ch36, pp77-8)


BACKGROUND: Risperidone, a potent antagonist of both serotonergic (5HT2A) and dopaminergic D2 receptors is associated with hyperprolactinemia in adults and children. Chronically elevated prolactin levels in children with prolactinomas may be associated with arrested growth and development resulting in either delayed puberty or short stature. These possibilities stress the importance of developing a safe and effective approach to drug-induced hyperprolactinemia in youth. We report the successful treatment of risperidone-induced hyperprolactinemia with cabergoline in youth. METHODS: We undertook a retrospective case review of four children with risperidone-induced hyperprolactinemia treated with cabergoline. RESULTS: Four males (age 6-11 years) with Diagnostic and Statistical Manual of Mental Disorders (fourth edition) bipolar disorder or psychoses, with risperidone-induced elevations in serum prolactin levels (57.5-129 ng/mL, normal 5-15 ng/mL), were treated with cabergoline (mean dose 2.13 +/- 0.09 mg/week). When serum prolactin levels normalized in all four subjects (mean 11.2 +/- 10.9 ng/mL), the cabergoline dose was reduced to 1 mg/week in three of four subjects. The mean duration of therapy with cabergoline was 523.5 +/- 129.7 days, and the mean duration of therapy with risperidone was 788.5 +/- 162.5 days. Cabergoline was well tolerated without adverse effects. CONCLUSIONS: Cabergoline may be useful for the treatment of risperidone-induced hyperprolactinemia in youth; however, further research is needed.

We report a patient who developed cholestatic jaundice shortly after initiation of treatment with metformin hydrochloride. Ultrasound of the liver and abdominal CT were normal. An ERCP showed normal biliary anatomy. A percutaneous liver biopsy was obtained showing marked cholestasis, with portal edema, ductular proliferation, and acute inflammation. Metformin hydrochloride was discontinued, and the patient's jaundice resolved slowly over a period of several months. Given the onset of his jaundice 2 wk after the initiation of metformin, we believe that this case represents an example of metformin-associated hepatotoxicity, the first such case reported.

Blindness Day Disabilities Vision Disability Disorder Visual Disorders Hemeralopia Hemeralopias Impairment Impairments Macropsia Macropsias Metamorphopsia Metamorphopsias Micropsia Micropsias

Visual impairments limiting one or more of the basic functions of the eye: visual acuity, dark adaptation, color vision, or peripheral vision. These may result from EYE DISEASES; OPTIC NERVE DISEASES; VISUAL PATHWAY diseases; OCCIPITAL LOBE diseases; OCULAR MOTILITY DISORDERS; and other conditions (From Newell, Ophthalmology: Principles and Concepts, 7th ed, p132).


PURPOSE: Symptomatic visual field constriction thought to be associated with vigabatrin has been reported. The current study investigated the visual fields and visual electrophysiology of eight patients with known vigabatrin-attributed visual field loss, three of whom were reported previously. Six of the patients were no longer receiving vigabatrin. METHODS: The central and peripheral fields were examined with the Humphrey Visual Field Analyzer. Full visual electrophysiology, including flash electroretinography (ERG), pattern electroretinography, multifocal ERG using the VERIS system, electro-oculography, and flash and pattern visual evoked potentials, was undertaken. RESULTS: Seven patients showed marked visual field constriction with some sparing of the temporal visual field. The eighth exhibited concentric constriction. Most electrophysiological responses were usually just within normal limits; two patients had subnormal Arden electro-oculography indices; and one patient showed an abnormally delayed photopic b wave. However, five patients showed delayed 30-Hz flicker b waves, and seven patients showed delayed oscillatory potentials. Multifocal ERG showed abnormalities that sometimes correlated with the visual field appearance and confirmed that the deficit occurs at the retinal level. CONCLUSION: Marked visual field constriction appears to be associated with vigabatrin therapy. The field defects and some electrophysiological abnormalities persist when vigabatrin therapy is withdrawn.


Conversion to rapamycin immunosuppression in renal transplant recipients: report of an initial experience.

AY 22 989 22-989 22989 I 2190A I-2190A I2190A Rapamune Rapamycin Sirolimus Wyeth Brand of

A macrolide compound obtained from Streptomyces hygroscopicus that acts by selectively blocking the transcriptional activation of cytokines thereby inhibiting cytokine production. It is bioactive only when bound to IMMUNOPHILINS. Sirolimus is a potent immunosuppressant and possesses both antifungal and antineoplastic properties.


BACKGROUND: The aim of this study is to evaluate the effects of RAPA conversion in patients undergoing cyclosporine (CsA) or tacrolimus (Tac) toxicity. METHODS: Twenty renal transplant recipients were switched to fixed dose rapamycin (RAPA) (5 mg/day) 0 to 204 months posttransplant. Drug monitoring was not initially used to adjust doses. The indications for switch were chronic CsA or Tac nephrotoxicity (12), acute CsA or Tac toxicity (3), severe facial dysmorphism (2), posttransplant lymphoproliferative disorder (PTLD) in remission (2), and hepatotoxicity in 1. Follow-up is 7 to 24 months. RESULTS: In the 12 patients switched because of chronic nephrotoxicity there was a significant decrease in serum creatinine [233+/-34 to 210+/-56 micromol/liter (P<0.05) at 6 months]. Facial dysmorphism improved in two patients. No relapse of PTLD was observed. Five patients developed pneumonia (two Pneumocystis carinii pneumonia, one infectious mononucleosis with polyclonal PTLD lung infiltrate) and two had bronchiolitis obliterans. There were no deaths. RAPA was discontinued in four patients, because of pneumonia in two, PTLD in one, and oral aphtous ulcers in one. RAPA levels were high (>15 ng/ml) in 7 of 13 (54%) patients. CONCLUSIONS: RAPA conversion provides adequate immunosuppression to enable CsA withdrawal. However, when converting patients to RAPA drug levels should be monitored to avoid over-immunosuppression and adequate antiviral and Pneumocystis carinii pneumonia prophylaxis should be given.

Drug-Induced Dyskinesia Dyskinesias Drug Induced Medication Medication-Induced

Abnormal movements, including HYPERKINESIS; HYPOKINESIA; TREMOR; and DYSTONIA, associated with the use of certain medications or drugs. Muscles of the face, trunk, neck, and extremities are most commonly affected. Tardive dyskinesia refers to abnormal hyperkinetic movements of the muscles of the face, tongue, and neck associated with the use of neuroleptic agents (see ANTIPSYCHOTIC AGENTS). (Adams et al., Principles of Neurology, 6th ed, p1199)


Ten patients who had Parkinson's disease with disabling dyskinesia were included in this study to evaluate the role of mental (mental calculation) and motor (flexion/extension of right fingers, flexion/extension of left fingers, flexion/extension of the neck, speaking aloud) tasks on the worsening of peak-dose dyskinesia following administration of an effective single dose of apomorphine. Compared with the score at rest (1.3+/-0.3), a significant aggravation of the dyskinesia score was observed during speaking aloud (5.2+/-1.1, p<0.05), movements of right (4.5+/-1.0, p<0.05) and left (3.7+/-0.8, p<0.05) fingers, movements of the neck (5.1+/-1.0, p<0.05), and mental calculation (3.1+/-1.0, p<0.05). These results suggest that activation tasks such as "speaking aloud" could be used for objective assessment of dyskinesia severity.

Cardiomyopathies Primary Secondary Cardiomyopathy Disease Myocardial Diseases Myocardiopathies Myocardiopathy

A group of diseases in which the dominant feature is the involvement of the CARDIAC MUSCLE itself. Cardiomyopathies are classified according to their predominant pathophysiological features (DILATED CARDIOMYOPATHY; HYPERTROPHIC CARDIOMYOPATHY; RESTRICTIVE CARDIOMYOPATHY) or their etiological/pathological factors (CARDIOMYOPATHY, ALCOHOLIC; ENDOCARDIAL FIBROELASTOSIS).


The use of adriamycin (ADR) in cancer chemotherapy has been limited due to its cumulative cardiovascular toxicity. Earlier observations that ADR interacts with mitochondrial cytochrome c oxidase (COX) and suppresses its enzyme activity led us to investigate ADR's action on the cardiovascular functions and heart mitochondrial morphology in Balb-c mice i.p. treated with ADR for several weeks. At various times during treatment, the animals were assessed for cardiovascular functions by electrocardiography and for heart tissue damage by electron microscopy. In parallel, total RNA was extracted from samples of dissected heart and analyzed by Northern blot hybridization to determine the steady-state level of three RNA transcripts encoded by the COXII, COXIII, and COXIV genes. Similarly, samples obtained from the liver of the same animals were analyzed for comparative studies. Our results indicated that 1) treatment of mice with ADR caused cardiovascular arrhythmias characterized by bradycardia, extension of ventricular depolarization time (tQRS), and failure of QRS at high concentrations (10-14 mg/kg body weight cumulative dose); 2) the heart mitochondria underwent swelling, fusion, dissolution, and/or disruption of mitochondrial cristae after several weeks of treatment. Such abnormalities were not observed in the mitochondria of liver tissue; and 3) among the three genes of COX enzyme examined, only COXII gene expression was suppressed by ADR treatment, mainly after 8 weeks in both heart and liver. Knowing that heart mitochondria represent almost 40% of heart muscle by weight, we conclude that the deteriorating effects of ADR on cardiovascular function involve mitochondrial structural and functional impairment.

Enhanced bradycardia induced by beta-adrenoceptor antagonists in rats pretreated with isoniazid.


Acid Vanillylidenehydrazide Isonicotinic Ftivazide Hydrazide Isonex Isoniazid Phthivazid Phthivazide Tubazide

Antibacterial agent used primarily as a tuberculostatic. It remains the treatment of choice for tuberculosis.


High doses of isoniazid increase hypotension induced by vasodilators and change the accompanying reflex tachycardia to bradycardia, an interaction attributed to decreased synthesis of brain gamma-aminobutyric acid (GABA). In the present study, the possible enhancement by isoniazid of bradycardia induced by beta-adrenoceptor antagonists was determined in rats anaesthetised with chloralose-urethane. Isoniazid significantly increased bradycardia after propranolol, pindolol, labetalol and atenolol, as well as after clonidine, but not after hexamethonium or carbachol. Enhancement was not observed in rats pretreated with methylatropine or previously vagotomised. These results are compatible with interference by isoniazid with GABAergic inhibition of cardiac parasympathetic tone. Such interference could be exerted centrally, possibly at the nucleus ambiguus, or peripherally at the sinus node.

The disease is marked by a wide range of system dysfunctions, an elevated erythrocyte sedimentation rate, and the formation of LE cells in the blood or bone marrow.


Aura Auras Awakening Epilepsy Cryptogenic Epilepsies Epileptic Seizure Seizures Disorder Disorders Single

A disorder characterized by recurrent episodes of paroxysmal brain dysfunction due to a sudden, disorderly, and excessive neuronal discharge. Epilepsy classification systems are generally based upon: (1) clinical features of the seizure episodes (e.g., motor seizure), (2) etiology (e.g., post-traumatic), (3) anatomic site of seizure origin (e.g., frontal lobe seizure), (4) tendency to spread to other structures in the brain, and (5) temporal patterns (e.g., nocturnal epilepsy). (From Adams et al., Principles of Neurology, 6th ed, p313)


OBJECTIVE: To study the effect of folic acid-containing multivitamin supplementation in epileptic women before and during pregnancy in order to determine the rate of structural birth defects and epilepsy-related side effects. STUDY DESIGN: First a randomised trial, later periconception care including in total 12225 females. RESULTS: Of 60 epileptic women with periconceptional folic acid (0.8 mg)-containing multivitamin supplementation, no one developed epilepsy-related side effects during the periconception period. One epileptic woman delivered a newborn with cleft lip and palate. Another patient exhibited with a cluster of seizures after the periconception period using another multivitamin. This 22-year-old epileptic woman was treated continuously by carbamazepine and a folic acid (1 mg)-containing multivitamin from the 20th week of gestation. She developed status epilepticus and later symptoms of systemic lupus erythematodes. Her pregnancy ended with stillbirth. CONCLUSIONS: The epileptic pregnant patient's autoimmune disease (probably drug-induced lupus) could damage the blood-brain barrier, therefore the therapeutic dose (> or =1 mg) of folic acid triggered a cluster of seizures. Physiological dose (<1 mg) of folic acid both in healthy and 60 epileptic women, all without any autoimmune disease, did not increase the risk for epileptic seizures.


Abnormalities Drug Induced Drug-Induced Abnormality

Absence Status Complex Partial Epilepticus Electrographic Generalized Convulsive Grand Mal Non Non-Convulsive Petit Simple Subclinical

A prolonged seizure or seizures repeated frequently enough to prevent recovery between episodes occurring over a period of 20-30 minutes. The most common subtype is generalized tonic-clonic status epilepticus, a potentially fatal condition associated with neuronal injury and respiratory and metabolic dysfunction. Nonconvulsive forms include petit mal status and complex partial status, which may manifest as behavioral disturbances. Simple partial status epilepticus consists of persistent motor, sensory, or autonomic seizures that do not impair cognition (see also EPILEPSIA PARTIALIS CONTINUA). Subclinical status epilepticus generally refers to seizures occurring in an unresponsive or comatose individual in the absence of overt signs of seizure activity.

Colitides Mucous Colitis Colon Irritable Bowel Syndrome Syndromes

A disorder with chronic or recurrent colonic symptoms without a clearcut etiology. This condition is characterized by chronic or recurrent ABDOMINAL PAIN, bloating, MUCUS in FECES, and an erratic disturbance of DEFECATION.


BACKGROUND: Irritable bowel syndrome is a common cause of abdominal pain and discomfort and may be related to disordered gastrointestinal motility. Our aim was to assess the effects of long-term treatment with a prokinetic agent, cisapride, on postprandial jejunal motility and symptoms in the irritable bowel syndrome (IBS). METHODS: Thirty-eight patients with IBS (constipation-predominant, n = 17; diarrhoea-predominant, n = 21) underwent 24-h ambulatory jejunal manometry before and after 12 week's treatment [cisapride, 5 mg three times daily (n = 19) or placebo (n = 19)]. RESULTS: In diarrhoea-predominant patients significant differences in contraction characteristics were observed between the cisapride and placebo groups. In cisapride-treated diarrhoea-predominant patients the mean contraction amplitude was higher (29.3 +/- 3.2 versus 24.9 +/- 2.6 mm Hg, cisapride versus placebo (P < 0.001); pretreatment, 25.7 +/- 6.0 mm Hg), the mean contraction duration longer (3.4 +/- 0.2 versus 3.0 +/- 0.2 sec, cisapride versus placebo (P < 0.001); pretreatment, 3.1 +/- 0.5 sec), and the mean contraction frequency lower (2.0 +/- 0.2 versus 2.5 +/- 0.4 cont./min, cisapride versus placebo (P < 0.001); pretreatment, 2.5 +/- 1.1 cont./min] than patients treated with placebo. No significant differences in jejunal motility were found in the constipation-predominant IBS group. Symptoms were assessed by using a visual analogue scale before and after treatment. Symptom scores relating to the severity of constipation were lower in cisapride-treated constipation-predominant IBS patients [score, 54 +/- 5 versus 67 +/- 14 mm, cisapride versus placebo (P < 0.05); pretreatment, 62 +/- 19 mm]. Diarrhoea-predominant IBS patients had a higher pain score after cisapride therapy [score, 55 +/- 15 versus 34 +/- 12 mm, cisapride versus placebo (P < 0.05); pretreatment, 67 +/- 19 mm]. CONCLUSION: Cisapride affects jejunal contraction characteristics and some symptoms in IBS.

6-O-Methylerythromycin A 56268 A-56268 A56268 Biaxin Clarithromycin TE 031 TE-031 TE031

A semisynthetic macrolide antibiotic derived from ERYTHROMYCIN that is active against a variety of microorganisms. It can inhibit PROTEIN SYNTHESIS in BACTERIA by reversibly binding to the 50S ribosomal subunits. This inhibits the translocation of aminoacyl transfer-RNA and prevents peptide chain elongation.


An abnormally rapid ventricular rhythm usually in excess of 150 beats per minute. It is generated within the ventricle below the BUNDLE OF HIS, either as autonomic impulse formation or reentrant impulse conduction. Depending on the etiology, onset of ventricular tachycardia can be paroxysmal (sudden) or nonparoxysmal, its wide QRS complexes can be uniform or polymorphic, and the ventricular beating may be independent of the atrial beating (AV dissociation).


Clarithromycin is a relatively new macrolide antibiotic that offers twice-daily dosing. It differs from erythromycin only in the methylation of the hydroxyl group at position 6. Although the side-effect profile of erythromycin is established, including gastroenteritis and interactions with other drugs subject to hepatic mixed-function oxidase metabolism, experience with the newer macrolides is still being recorded. Cardiotoxicity has been demonstrated after both intravenous and oral administration of erythromycin but has never been reported with the newer macrolides. We report a case of ventricular dysrhythmias that occurred after six therapeutic doses of clarithromycin. The dysrhythmias resolved after discontinuation of the drug.

ADH-Resistant Diabetes Insipidus Acquired Nephrogenic Congenital Renalis Autosomal Type 1 I II X-Linked Vasopressin-Resistant

A genetic or acquired polyuric disorder characterized by persistent hypotonic urine and HYPOKALEMIA. This condition is due to renal tubular insensitivity to VASOPRESSIN and failure to reduce urine volume. It may be the result of mutations of genes encoding VASOPRESSIN RECEPTORS or AQUAPORIN-2; KIDNEY DISEASES; adverse drug effects; or complications from PREGNANCY.


An element in the alkali metals family. It has the atomic symbol Li, atomic number 3, and atomic weight [6.938; 6.997]. Salts of lithium are used in treating BIPOLAR DISORDER.


We report the case of a patient who developed severe hypernatraemic dehydration following a head injury. Ten years previously he had been diagnosed to have lithium-induced nephrogenic diabetes insipidus, and lithium therapy had been discontinued. He remained thirsty and polyuric despite cessation of lithium and investigations on admission showed him to have normal osmoregulated thirst and vasopressin secretion, with clear evidence of nephrogenic diabetes insipidus. Lithium induced nephrogenic diabetes insipidus is considered to be reversible on cessation of therapy but polyuria persisted in this patient for ten years after lithium was stopped. We discuss the possible renal mechanisms and the implications for management of patients with lithium-induced nephrogenic diabetes insipidus.

The condition that results from excessive loss of water from a living organism.

Antidiuretic hormones released by the NEUROHYPOPHYSIS of all vertebrates (structure varies with species) to regulate water balance and OSMOLARITY. In general, vasopressin is a nonapeptide consisting of a six-amino-acid ring with a cysteine 1 to cysteine 6 disulfide bridge or an octapeptide containing a CYSTINE. All mammals have arginine vasopressin except the pig with a lysine at position 8. Vasopressin, a vasoconstrictor, acts on the KIDNEY COLLECTING DUCTS to increase water reabsorption, increase blood volume and blood pressure.


Late cardiotoxicity after treatment for a malignant bone tumor.


Tumors or cancer located in bone tissue or specific BONES.


Cardiac function was assessed in long-term survivors of malignant bone tumors who were treated according to Rosen's T5 or T10 protocol, both including doxorubicin. Thirty-one patients, age 10-45 years (median age 17.8 years) were evaluated 2.3-14.1 years (median 8.9 years) following completion of treatment. Cumulative doses of doxorubicin were 225-550 mg/m2 (median dose 360). The evaluation consisted of a history, physical examination, electrocardiogram (ECG), signal averaged ECG, 24-hour ambulatory ECG, echocardiography and radionuclide angiography. Eighteen of 31 (58%) patients showed cardiac toxicity, defined as having one or more of the following abnormalities: late potentials, complex ventricular arrhythmias, left ventricular dilation, decreased shortening fraction, or decreased ejection fraction. The incidence of cardiac abnormalities increased with length of follow-up (P< or = .05). No correlation could be demonstrated between cumulative dose of doxorubicin and cardiac status, except for heart rate variability. When adjusted to body surface area, the left ventricular posterior wall thickness (LVPW index) was decreased in all patients. The incidence of doxorubicin-induced cardiotoxicity is high and increases with follow-up, irrespective of cumulative dose. Life-long cardiac follow-up in these patients is warranted. The results of our study suggest that heart rate variability and LVPW index could be sensitive indicators for cardiotoxicity.

Although some studies have suggested fewer venous complications are associated with midazolam than with diazepam for endoscopic procedures, this variable has not been well documented. We prospectively evaluated the incidence of venous complications after intravenous injection of diazepam or midazolam in 122 consecutive patients undergoing colonoscopy and esophagogastroduodenoscopy. Overall, venous complications were more frequent with diazepam (22 of 62 patients) than with midazolam (4 of 60 patients) (p < 0.001). A palpable venous cord was present in 23% (14 of 62) of patients in the diazepam group, compared with 2% (1 of 60 patients) in the midazolam group (p < 0.002). Pain at the injection site occurred in 35% (22 of 62) of patients in the diazepam group compared with 7% (4 of 60 patients) in the midazolam group (p < 0.001). Swelling and warmth at the injection site were not significantly different between the two groups. Smoking, nonsteroidal anti-inflammatory drug use, intravenous catheter site, dwell time of the needle, alcohol use, and pain during the injection had no effect on the incidence of venous complications.

Auditory Seizure Seizures Clonic Convulsion Non Epileptic Non-Epileptic Convulsions Convulsive Focal Generalized Gustatory Jacksonian Motor Olfactory Sensory Somatosensory Tonic Tonic-Clonic Vertiginous Vestibular Visual

Clinical or subclinical disturbances of cortical function due to a sudden, abnormal, excessive, and disorganized discharge of brain cells. Clinical manifestations include abnormal motor, sensory and psychic phenomena. Recurrent seizures are usually referred to as EPILEPSY or "seizure disorder."


In situ hybridization methods were used to determine if glutamic acid decarboxylase (GAD) mRNA-containing neurons within the hilus of the dentate gyrus are vulnerable to seizure-induced damage in a model of chronic seizures. Sprague-Dawley rats were injected intraperitoneally with pilocarpine, and the hippocampal formation was studied histologically at 1, 2, 4, and 8 week intervals after pilocarpine-induced seizures. In situ hybridization histochemistry, using a digoxigenin-labeled GAD cRNA probe, demonstrated a substantial decrease in the number of GAD mRNA-containing neurons in the hilus of the dentate gyrus in the pilocarpine-treated rats as compared to controls at all time intervals. Additional neuronanatomical studies, including cresyl violet staining, neuronal degeneration methods, and histochemical localization of glial fibrillary acidic protein, suggested that the decrease in the number of GAD mRNA-containing neurons was related to neuronal loss rather than to a decrease in GAD mRNA levels. The loss of GAD mRNA-containing neurons in the hilus contrasted with the relative preservation of labeled putative basket cells along the inner margin of the granule cell layer. Quantitative analyses of labeled neurons in three regions of the dentate gyrus in the 1 and 2 week groups showed statistically significant decreases in the mean number of GAD mRNA-containing neurons in the hilus of both groups of experimental animals. No significant differences were found in the molecular layer or the granule cell layer, which included labeled neurons along the lower margin of the granule cell layer. The results indicate that, in this model, a subpopulation of GAD mRNA-containing neurons within the dentate gyrus is selectively vulnerable to seizure-induced damage. Such differential vulnerability appears to be another indication of the heterogeneity of GABA neurons.

Pathological processes of the KIDNEY or its component tissues.


OBJECTIVE: To evaluate the possible protective effects of misoprostol on renal function in hospitalized elderly patients treated with indomethacin. METHODS: Forty-five hospitalized elderly patients (> 65 years old) who required therapy with nonsteroidal antiinflammatory drugs (NSAID) were randomly assigned to receive either indomethacin, 150 mg/day (Group A), or indomethacin 150 mg/day plus misoprostol at 0.6 mg/day (Group B). Laboratory variables of renal function [serum creatinine, blood urea nitrogen (BUN) and electrolytes] were evaluated before initiation of therapy and every 2 days, until termination of the study (a period of at least 6 days). Response to treatment was estimated by the visual analog scale for severity of pain. RESULTS: Forty-two patients completed the study, 22 in Group A and 20 in Group B. BUN and creatinine increased by > 50% of baseline levels in 54 and 45% of Group A patients, respectively, compared to only 20 and 10% of Group B patients (p < 0.05). Potassium (K) increment of 0.6 mEq/l or more was observed in 50% of Group A, but in only 15% of Group B patients (p < 0.05). The mean increments in BUN, creatinine, and K were reduced by 63, 80, and 42%, respectively, in Group B patients compared to Group A. Response to treatment did not differ significantly between the 2 groups. CONCLUSION: Hospitalized elderly patients are at risk for developing indomethacin related renal dysfunction. Addition of misoprostol can minimize this renal impairment without affecting pain control.


The urea concentration of the blood stated in terms of nitrogen content. Serum (plasma) urea nitrogen is approximately 12% higher than blood urea nitrogen concentration because of the greater protein content of red blood cells. Increases in blood or serum urea nitrogen are referred to as azotemia and may have prerenal, renal, or postrenal causes.

Nephrotoxic effects of aminoglycoside treatment on renal protein reabsorption and accumulation.


Glycosylated compounds in which there is an amino substituent on the glycoside. Some of them are clinically important ANTIBIOTICS.


To quantify the effects of gentamicin, kanamycin and netilmicin on renal protein reabsorption and accumulation, these drugs were administered to rats intraperitoneally (30 mg/kg/day) for 7, 14 or 21 days. Scanning electron microscopy of the glomerular endothelia, urinary measurements of sodium, potassium, endogenous lysozyme, N-acetyl-beta-D-glucosaminidase (NAG) as well as clearance and accumulation experiments after i.v. administration of egg-white lysozyme and measurements of inulin clearance (GFR) were done in each treatment group. Gentamicin administration decreased diameter, density and shape of endothelial fenestrae. Kanamycin and netilmicin appeared to have no effect at the dose used. All three aminoglycosides decreased GFR and increased urinary excretion of sodium and potassium. While gentamicin and kanamycin decreased the percentage reabsorption and accumulation of lysozyme after i.v. administration of egg-white lysozyme netilmicin had no effect. Daily excretion of total protein, endogenous lysozyme and NAG increased only after treatment with kanamycin and gentamicin. Thus, aminoglycosides may act as nephrotoxicants at glomerular and/or tubular level inducing impairment of renal reabsorption and accumulation of proteins.

3 Hydroxy L tyrosine 3-Hydroxy-L-tyrosine Dopaflex Dopar 3,4 Dihydroxyphenylalanine Dopa L-3,4-Dihydroxyphenylalanine L-Dopa Larodopa Levodopa Levopa Medphano Brand of Roberts Roche

The naturally occurring form of DIHYDROXYPHENYLALANINE and the immediate precursor of DOPAMINE. Unlike dopamine itself, it can be taken orally and crosses the blood-brain barrier. It is rapidly taken up by dopaminergic neurons and converted to DOPAMINE. It is used for the treatment of PARKINSONIAN DISORDERS and is usually given with agents that inhibit its conversion to dopamine outside of the central nervous system.


Ammonia coma was produced in rats within 10 to 15 minutes of an intraperitonealinjection of 1.7 mmol NH4CL. This coma was prevented with 1.68 mmol L-dopa given by gastric intubation 15 minutes before the ammonium salt injection. The effect of L-dopa was correlated with a decrease in blood and brain ammonia, an increase in brain dopamine, and an increase in renal excretion of ammonia and urea. Intraventricular infusion of dopamine sufficient to raise the brain dopamine to the same extent did not prevent the ammonia coma nor affect the blood and brain ammonia concentrations. Bilateral nephrectomy eliminated the beneficial effect of L-dopa on blood and brain ammonia and the ammonia coma was not prevented. Thus, the reduction in blood and brain ammonia and the prevention of ammonia coma after L-dopa, can be accounted for by the peripheral effect of dopamine on renal function rather than its central action. These results provide a reasonable explanation for the beneficial effects observed in some encephalopathic patients receiving L-dopa.

Thrombocytopenia Thrombocytopenias Thrombopenia Thrombopenias


BACKGROUND: Unfractionated heparin sodium (UFH) or low-molecular weight heparin (LMWH) is used in anticoagulant protocols at several institutions to prevent thrombosis after liver transplantation. Heparin-induced thrombocytopenia (HIT) is an adverse immune-mediated reaction to heparin, resulting in platelet count decreases of more than 50%. The frequencies of HIT after liver transplantation and platelet factor 4/heparin-reactive antibody (HIT antibody) positivity in liver transplantation patients, however, are unknown. PATIENTS AND METHODS: The 32 men and 20 women underwent living donor liver transplantation. We started LMWH (25 IU/kg/h) on postoperative day (POD) 1, switching to UFH (5000 U/d) on POD 2 or 3. The dose of UFH was changed according to the activated clotting time level. HIT antibody levels were measured the day before surgery and on POD 7 and 14. Platelet count was measured daily for 3 weeks. RESULTS: The average platelet counts preoperatively, and on POD 7, 14, and 21 were 65, 88, 149, and 169 x 10(9)/L, respectively. Two patients developed hepatic artery thrombosis on POD 11 and 19, respectively, although they were HIT antibody-negative and their platelet counts were stable. In 2 other patients, the platelet count decreased suddenly from 107 x 10(9)/L on POD 4 to 65 x 10(9)/L on POD 6 and from 76 x 10(9)/L on POD 7 to 33 x 10(9)/L on POD 9, respectively. The heparin-induced platelet aggregation test was negative in these patients. The percentage of HIT antibody-positive patients was 0.5% preoperatively, 5.6% on POD 7, and 5.6% on POD 14. None of the subjects/patients developed UFH-related HIT. CONCLUSIONS: In our series, the occurrence of HIT after liver transplantation was uncommon.
