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."


Neuropeptide-Y (NPY) is expressed by granule cells and mossy fibres of the hippocampal dentate gyrus during experimental temporal lobe epilepsy (TLE). This expression may represent an endogenous damping mechanism since NPY has been shown to block seizure-like events following high-frequency stimulation in hippocampal slices. The pilocarpine (PILO) model of epilepsy is characterized by an acute period of status epilepticus followed by spontaneous recurrent seizures and related brain damage. We report peroxidase-antiperoxidase immunostaining for NPY in several brain regions in this model. PILO-injected animals exhibited NPY immunoreactivity in the region of the mossy fibre terminals, in the dentate gyrus inner molecular layer and, in a few cases, within presumed granule cells. NPY immunoreactivity was also dramatically changed in the entorhinal cortex, amygdala and sensorimotor areas. In addition, PILO injected animals exhibited a reduction in the number of NPY-immunoreactive interneurons compared with controls. The results demonstrate that changes in NPY expression, including expression in the granule cells and mossy fibres and the loss of vulnerable NPY neurons, are present in the PILO model of TLE. However, the significance of this changed synthesis of NPY remains to be determined.

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)


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.

Acute Brain Injuries Injury Contusion Contusions Diffuse Focal Traumatic Laceration Lacerations Trauma Traumas Cortical Encephalopathies Post-Concussive Post-Traumatic Encephalopathy Post Concussive Mild TBI (Traumatic Injury) TBIs

Acute and chronic (see also BRAIN INJURIES, CHRONIC) injuries to the brain, including the cerebral hemispheres, CEREBELLUM, and BRAIN STEM. Clinical manifestations depend on the nature of injury. Diffuse trauma to the brain is frequently associated with DIFFUSE AXONAL INJURY or COMA, POST-TRAUMATIC. Localized injuries may be associated with NEUROBEHAVIORAL MANIFESTATIONS; HEMIPARESIS, or other focal neurologic deficits.


PURPOSE: To assess by electrophysiologic testing the effect of photorefractive keratectomy (PRK) on the retina and optic nerve. SETTING: Eye Clinic, S. Salvatore Hospital, L'Aquila University, Italy. METHODS: Standard pattern electroretinograms (P-ERGs) and standard pattern visual evoked potentials (P-VEPs) were done in 25 eyes of 25 patients who had myopic PRK for an attempted correction between 5.00 and 15.00 diopters (D) (mean 8.00 D). Testing was done preoperatively and 3, 6, 12, and 18 months postoperatively. The contralateral eyes served as controls. During the follow-up, 3 patients (12%) developed steroid-induced elevated intraocular pressure (IOP) that resolved after corticosteroid therapy was discontinued. RESULTS: No statistically significant differences were seen between treated and control eyes nor between treated eyes preoperatively and postoperatively. CONCLUSION: Myopic excimer laser PRK did not seem to affect the posterior segment. The transient steroid-induced IOP rise did not seem to cause functional impairment.

Kaposi Sarcoma Kaposi's Kaposis Multiple Idiopathic Pigmented Hemangiosarcoma

A multicentric, malignant neoplastic vascular proliferation characterized by the development of bluish-red cutaneous nodules, usually on the lower extremities, most often on the toes or feet, and slowly increasing in size and number and spreading to more proximal areas. The tumors have endothelium-lined channels and vascular spaces admixed with variably sized aggregates of spindle-shaped cells, and often remain confined to the skin and subcutaneous tissue, but widespread visceral involvement may occur. Kaposi's sarcoma occurs spontaneously in Jewish and Italian males in Europe and the United States. An aggressive variant in young children is endemic in some areas of Africa. A third form occurs in about 0.04% of kidney transplant patients. There is also a high incidence in AIDS patients. (From Dorland, 27th ed & Holland et al., Cancer Medicine, 3d ed, pp2105-7) HHV-8 is the suspected cause.


We report a non-randomized Phase II clinical trial to assess the efficacy and safety of liposomal daunorubicin (DaunoXome) in the treatment of AIDS related Kaposi's sarcoma. Eleven homosexual men with advanced Kaposi's sarcoma were entered in the trial. Changes in size, colour and associated oedema of selected 'target' lesions were measured. Clinical, biochemical and haematological toxicities were assessed. Ten subjects were evaluated. A partial response was achieved in four, of whom two subsequently relapsed. Stabilization of Kaposi's sarcoma occurred in the remaining six, maintained until the end of the trial period in four. The drug was generally well tolerated, with few mild symptoms of toxicity. The main problem encountered was haematological toxicity, with three subjects experiencing severe neutropenia (neutrophil count < 0.5 x 10(9)/l). There was no evidence of cardiotoxicity. In this small patient sample, liposomal daunorubicin was an effective and well tolerated agent in the treatment of Kaposi's sarcoma.

Diseases of the central and peripheral nervous system. This includes disorders of the brain, spinal cord, cranial nerves, peripheral nerves, nerve roots, autonomic nervous system, neuromuscular junction, and muscle.


The neuropathy caused by a single dose of isoniazid in rats was studied with a computer-assisted morphometric method. Scatter diagrams of the g ratio (quotient fibre diameter/axon diameter) define regenerating fibres as a distinct population, distinguishable from the surviving fibres by reduced sheath thickness and reduced axon calibre. There was also evidence of a subtle direct toxic effect on the entire fibre population, causing axon shrinkage masked by readjustment of the myelin sheath.

A diagnostic radiopaque that usually occurs as the sodium salt.


A potentially lethal cardiac arrhythmia that is characterized by uncoordinated extremely rapid firing of electrical impulses (400-600/min) in HEART VENTRICLES. Such asynchronous ventricular quivering or fibrillation prevents any effective cardiac output and results in unconsciousness (SYNCOPE). It is one of the major electrocardiographic patterns seen with CARDIAC ARREST.


In twenty beagle dogs selective injections were made into the left coronary artery with iopentol, iohexol and metrizoate in doses of 4 ml, 8 ml and 16 ml. Thirty-six iopentol injections, 35 iohexol injections and 37 metrizoate injections were made. Frequencies of ventricular fibrillation were significantly lower (p less than 0.05) after iopentol (0%) and iohexol (3%) than after metrizoate (22%). Iopentol and iohexol also produced significantly less decrease in aortic blood pressure than metrizoate at the different doses.

Narrowing or constriction of a coronary artery.


A heavy, bluish white metal, atomic number 81, atomic weight [204.382; 204.385], symbol Tl.


It has been previously shown that myocardial contrast echocardiography is a valuable technique for delineating regions of myocardial underperfusion secondary to coronary occlusion and to critical coronary stenoses in the presence of hyperemic stimulation. The aim of this study was to determine whether myocardial contrast echocardiography performed with a stable solution of sonicated albumin could detect regions of myocardial underperfusion resulting from various degrees of coronary stenosis. The perfusion defect produced in 16 open chest dogs was compared with the anatomic area at risk measured by the postmortem dual-perfusion technique and with thallium-201 single-photon emission tomography (SPECT). During a transient (20-s) coronary occlusion, a perfusion defect was observed with contrast echocardiography in 14 of the 15 dogs in which the occlusion was produced. The perfusion defect correlated significantly with the anatomic area at risk (r = 0.74; p less than 0.002). During dipyridamole-induced hyperemia, 12 of the 16 dogs with a partial coronary stenosis had a visible area of hypoperfusion by contrast echocardiography. The four dogs without a perfusion defect had a stenosis that resulted in a mild (0% to 50%) reduction in dipyridamole-induced hyperemia. The size of the perfusion defect during stenosis correlated significantly with the anatomic area at risk (r = 0.61; p = 0.02). Thallium-201 SPECT demonstrated a perfusion defect in all 14 dogs analyzed during dipyridamole-induced hyperemia; the size of the perfusion defect correlated with the anatomic area at risk (r = 0.58; p less than 0.03) and with the perfusion defect by contrast echocardiography (r = 0.58; p less than 0.03). Thus, myocardial contrast echocardiography can be used to visualize and quantitate the amount of jeopardized myocardium during moderate to severe degrees of coronary stenosis. The results obtained show a correlation with the anatomic area at risk similar to that obtained with thallium-201 SPECT.

Pathological processes of the KIDNEY or its component tissues.


The purpose of the study was to determine the efficacy of furosemide in addition to intravenous fluids in the prevention of radiocontrast nephropathy. 18 patients, referred to a radiocontrast study, considered at risk because of preexisting renal insufficiency, were enrolled in a prospective, randomized, controlled trial, performed at the secondary care center of a 1,100-bed private university hospital. In addition to fluids, the treatment group received furosemide (mean dose 110 mg) intravenously 30 min prior to the injection of contrast material. The control group received fluids (mean 3 liters). Radiological studies were mostly angiographies performed with both ionic and non-ionic contrast material, at an average dose of 245 ml. Renal function significantly deteriorated in the group pretreated with furosemide (p < 0.005 by ANOVA), with a rise in serum creatinine from 145 +/- 13 to 182 +/- 16 mumol/l at 24 h, while no change occurred in the control group (from 141 +/- 6 to 142 +/- 7 mumol/l). Renal failure was associated with weight loss in the furosemide-treated group. Furosemide may be deleterious in the prevention of radiocontrast nephropathy.

Etiologic factors in the pathogenesis of liver tumors associated with oral contraceptives.

Cancer of Liver the Hepatic Hepatocellular Cancers Neoplasm Neoplasms


Within the last several years, previously rare liver tumors have been seen in young women using oral contraceptive steroids. The Registry for Liver Tumors Associated with Oral Contraceptives at the University of California, Irvine, has clearly identified 27 cases. The recent literature contains 44 case reports. Common to these 71 cases has been a histopathologic diagnosis of focal nodular hyperplasia, adenoma, hamartoma, and hepatoma. Significant statistical etiologic factors include prolonged uninterrupted usage of oral contraceptive steroids. Eight deaths and liver rupture in 18 patients attest to the seriousness of this new potentially lethal adverse phenomenon.

A calcineurin inhibitor combined with methotrexate is the standard prophylaxis for graft-versus-host disease (GVHD) after allogeneic hematopoietic stem cell transplantation (HSCT). Everolimus, a derivative of sirolimus, seems to mediate antileukemia effects. We report on a combination of everolimus and tacrolimus in 24 patients (median age, 62 years) with either myelodysplastic syndrome (MDS; n = 17) or acute myeloid leukemia (AML; n = 7) undergoing intensive conditioning followed by HSCT from related (n = 4) or unrelated (n = 20) donors. All patients engrafted, and only 1 patient experienced grade IV mucositis. Nine patients (37%) developed acute grade II-IV GVHD, and 11 of 17 evaluable patients (64%) developed chronic extensive GVHD. Transplantation-associated microangiopathy (TMA) occurred in 7 patients (29%), with 2 cases of acute renal failure. The study was terminated prematurely because an additional 6 patients (25%) developed sinusoidal obstruction syndrome (SOS), which was fatal in 2 cases. With a median follow-up of 26 months, the 2-year overall survival rate was 47%. Although this new combination appears to be effective as a prophylactic regimen for acute GVHD, the incidence of TMA and SOS is considerably higher than seen with other regimens.

A fatty acid with anticonvulsant properties used in the treatment of epilepsy. The mechanisms of its therapeutic actions are not well understood. It may act by increasing GAMMA-AMINOBUTYRIC ACID levels in the brain or by altering the properties of voltage dependent sodium channels.


Antelepsin Clonazepam Rivotril Ro 5-4023 54023

An anticonvulsant used for several types of seizures, including myotonic or atonic seizures, photosensitive epilepsy, and absence seizures, although tolerance may develop. It is seldom effective in generalized tonic-clonic or partial seizures. The mechanism of action appears to involve the enhancement of GAMMA-AMINOBUTYRIC ACID receptor responses.


Loreclezole (5 mg/kg) exerted a significant protective action in amygdala-kindled rats, reducing both seizure and afterdischarge durations. The combinations of loreclezole (2.5 mg/kg) with valproate, clonazepam, or carbamazepine (applied at their subprotective doses) also exhibited antiseizure effect in this test. However, only two first combinations occurred to be of pharmacodynamic nature. Among several chemoconvulsants, bicuculline, N-methyl-D-aspartic acid and BAY k-8644 (the opener of L-type calcium channels) reversed the protective activity of loreclezole alone and its combination with valproate. On the other hand, bicuculline, aminophylline and BAY k-8644 inhibited the anticonvulsive action of loreclezole combined with clonazepam. The results support the hypothesis that the protective activity of loreclezole and its combinations with other antiepileptics may involve potentiation of GABAergic neurotransmission and blockade of L-type of calcium channels.

Acute liver failure with concurrent bupropion and carbimazole therapy.

Acute Hepatic Failure Liver Fulminant Failures Fulminating

A form of rapid-onset LIVER FAILURE, also known as fulminant hepatic failure, caused by severe liver injury or massive loss of HEPATOCYTES. It is characterized by sudden development of liver dysfunction and JAUNDICE. Acute liver failure may progress to exhibit cerebral dysfunction even HEPATIC COMA depending on the etiology that includes hepatic ISCHEMIA, drug toxicity, malignant infiltration, and viral hepatitis such as post-transfusion HEPATITIS B and HEPATITIS C.

OBJECTIVE: To report a case of fatal liver failure possibly associated with concurrent use of bupropion and carbimazole. CASE SUMMARY: A 41-year-old Chinese man with a history of hyperthyroidism had been treated with carbimazole and propranolol for the past 5 years. He received a 10-day course of bupropion as an aid for smoking cessation 10 weeks prior to presentation. He developed acute liver failure with rapid deterioration of renal function. Liver biopsy showed evidence of nonspecific drug-induced acute liver injury. His condition was further complicated by sepsis and coagulopathy. Death resulted 19 days after the onset of symptoms. The likelihood that bupropion induced hepatotoxicity in our patient was possible, based on the Naranjo probability scale. DISCUSSION: Although there is increasing evidence of hepatotoxicity induced by bupropion, this is the first case of fatality that could have resulted from acute liver failure in a patient receiving bupropion while on concomitant treatment with carbimazole. CONCLUSIONS: Clinicians should be aware of the possibility of acute liver insult induced by bupropion given concurrently with other hepatotoxic drugs.

BACKGROUND: Hormone therapy (HT) is widely used for controlling menopausal symptoms and has also been used for the management and prevention of cardiovascular disease, osteoporosis and dementia in older women. This is an updated version of the original Cochrane review first published in 2005. OBJECTIVES: To assess the effect of long-term HT on mortality, cardiovascular outcomes, cancer, gallbladder disease, cognition, fractures and quality of life. SEARCH STRATEGY: We searched the following databases to November 2007: Trials Register of the Cochrane Menstrual Disorders and Subfertility Group, Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, Biological Abstracts. Also relevant non-indexed journals and conference abstracts. SELECTION CRITERIA: Randomised double-blind trials of HT versus placebo, taken for at least one year by perimenopausal or postmenopausal women. HT included oestrogens, with or without progestogens, via oral, transdermal, subcutaneous or transnasal routes. DATA COLLECTION AND ANALYSIS: Two authors independently assessed trial quality and extracted data. MAIN RESULTS: Nineteen trials involving 41,904 women were included. In relatively healthy women, combined continuous HT significantly increased the risk of venous thrombo-embolism or coronary event (after one year's use), stroke (after three years), breast cancer and gallbladder disease. Long-term oestrogen-only HT significantly increased the risk of venous thrombo-embolism, stroke and gallbladder disease (after one to two years, three years and seven years' use respectively), but did not significantly increase the risk of breast cancer. The only statistically significant benefits of HT were a decreased incidence of fractures and (for combined HT) colon cancer, with long-term use. Among women aged over 65 who were relatively healthy (i.e. generally fit, without overt disease) and taking continuous combined HT, there was a statistically significant increase in the incidence of dementia. Among women with cardiovascular disease, long-term use of combined continuous HT significantly increased the risk of venous thrombo-embolism.One trial analysed subgroups of 2839 relatively healthy 50 to 59 year old women taking combined continuous HT and 1637 taking oestrogen-only HT, versus similar-sized placebo groups. The only significantly increased risk reported was for venous thrombo-embolism in women taking combined continuous HT: their absolute risk remained low, at less than 1/500. However, this study was not powered to detect differences between groups of younger women. AUTHORS' CONCLUSIONS: HT is not indicated for the routine management of chronic disease. We need more evidence on the safety of HT for menopausal symptom control, though short-term use appears to be relatively safe for healthy younger women.

Passage of mannitol into the brain around gliomas: a potential cause of rebound phenomenon. A study on 21 patients.

(L)-Mannitol Mannitol Osmitrol Osmofundin

A diuretic and renal diagnostic aid related to sorbitol. It has little significant energy value as it is largely eliminated from the body before any metabolism can take place. It can be used to treat oliguria associated with kidney failure or other manifestations of inadequate renal function and has been used for determination of glomerular filtration rate. Mannitol is also commonly used as a research tool in cell biological studies, usually to control osmolarity.


Glial Cell Tumor Tumors Glioma Malignant Mixed Gliomas

Benign and malignant central nervous system neoplasms derived from glial cells (i.e., astrocytes, oligodendrocytes, and ependymocytes). Astrocytes may give rise to astrocytomas (ASTROCYTOMA) or glioblastoma multiforme (see GLIOBLASTOMA). Oligodendrocytes give rise to oligodendrogliomas (OLIGODENDROGLIOMA) and ependymocytes may undergo transformation to become EPENDYMOMA; CHOROID PLEXUS NEOPLASMS; or colloid cysts of the third ventricle. (From Escourolle et al., Manual of Basic Neuropathology, 2nd ed, p21)


AIM: Widespread use of mannitol to reduce brain edema and lower elevated ICP in brain tumor patients continues to be afflicted by the so-called rebound phenomenon. Leakage of mannitol into the brain parenchyma through an altered BBB and secondary reversal of osmotic gradient is considered the major cause of rebound . This has only been demonstrated experimentally in animals. As a contribution to this issue we decided to research the possible passage of mannitol into the brain after administration to 21 brain tumor patients. METHODS: Mannitol (18% solution; 1 g/kg) was administered as a bolus to patients (ten had malignant glioma, seven brain metastases and four meningioma) about 30 minutes before craniotomy. During resection, a sample of the surrounding edematous white matter was taken at the same time as a 10 ml venous blood sample. Mannitol concentrations were measured in plasma and white matter by a modified version of the enzyme assay of Blonquist et al. RESULTS: In most glioma patients, mannitol concentrations in white matter were 2 to 6 times higher than in plasma (mean 3.5 times). In meningioma and metastases patients plasma concentrations of mannitol were higher than white matter concentrations except in three cases with infiltration by neoplastic cells. CONCLUSIONS: The results of our study show that even after a single bolus, mannitol may leak through the altered BBB near gliomas, reversing the initial plasma-to-blood osmotic gradient, aggravating peritumoral edema and promoting rebound of ICP.


Brain Edema Cytotoxic Vasogenic Swelling Swellings Cerebral Edemas Intracranial

Increased intracellular or extracellular fluid in brain tissue. Cytotoxic brain edema (swelling due to increased intracellular fluid) is indicative of a disturbance in cell metabolism, and is commonly associated with hypoxic or ischemic injuries (see HYPOXIA, BRAIN). An increase in extracellular fluid may be caused by increased brain capillary permeability (vasogenic edema), an osmotic gradient, local blockages in interstitial fluid pathways, or by obstruction of CSF flow (e.g., obstructive HYDROCEPHALUS).

A quaternary skeletal muscle relaxant usually used in the form of its bromide, chloride, or iodide. It is a depolarizing relaxant, acting in about 30 seconds and with a duration of effect averaging three to five minutes. Succinylcholine is used in surgical, anesthetic, and other procedures in which a brief period of muscle relaxation is called for.


This study was undertaken to determine the effect of lidocaine pretreatment on reduction of succinylcholine-induced myalgia in patients undergoing general anesthesia for gynecological surgery. One hundred and thirty-five patients were assigned to one of three groups in a prospective, double blind, randomized manner. Group PS, the control group, received normal saline and succinylcholine 1.5 mg x kg(-1); Group LS, lidocaine 1.5 mg x kg(-1) and succinylcholine 1.5 mg x kg(-1); Group PR, normal saline and rocuronium 0.6 mg x kg(-1). Morphine 0.1 mg x kg(-1) iv was given for premedication and all patients were monitored with a noninvasive blood pressure monitor, ECG and pulse oximetry. Anesthesia was induced with 5 mg.kg(-1) thiopental iv. followed by succinylcholine (Group PS, LS) or rocuronium (Group PR) for tracheal intubation. Following administration of these agents, the presence, and degree of fasciculation were assessed visually on a four point scale by one investigator who was blinded to the drug administered. The blood pressure and heart rate of each patient were monitored on nine occasions. Twenty-four hours later, any myalgia experienced was assessed according to a structured questionaire and graded by a four point scale by one investigator blinded to the intraoperative management. The results indicate that muscle fasciculation was not found in Group PR while the patients in Group LS had a lower incidence of muscle fasciculation than those in Group PS (p < 0.001). At 24 h, the incidence of myalgia was higher in Group PS than in Group LS and PR (p < 0.05). A correlation was not found between the incidence of myalgia and the occurrence of muscle fasciculation. The changes in systolic and diastolic blood pressure and heart rate were not significant among the three groups. In conclusion, where succinylcholine is used, lidocaine is proven to be the useful pretreatment agent for the reduction of postoperative myalgia.

Open-label assessment of levofloxacin for the treatment of acute bacterial sinusitis in adults.

Anhydrous Levofloxacin Levaquin Ofloxacin (S)-Isomer Quixin


Inflammation of the NASAL MUCOSA in one or more of the PARANASAL SINUSES.


PURPOSE: To evaluate the efficacy and safety of levofloxacin (500 mg orally once daily for 10 to 14 days) in treating adult outpatients with acute bacterial sinusitis. PATIENTS AND METHODS: A total of 329 patients enrolled in the study at 24 centers. All patients had a pre-therapy Gram's stain and culture of sinus exudate obtained by antral puncture or nasal endoscopy. Clinical response was assessed on the basis of signs and symptoms and sinus radiograph or computed tomography results. Microbiologic cure rates were determined on the basis of presumed plus documented eradication of the pre-therapy pathogen(s). RESULTS: The most common pathogens were Haemophilus influenzae, Streptococcus pneumoniae, Staphylococcus aureus, and Moraxella catarrhalis. Of 300 clinically evaluable patients, 175 (58%) were cured and 90 (30%) were improved at the post-therapy evaluation, resulting in a clinical success rate of 88%. Thirty-five patients (12%) clinically failed treatment. The microbiologic eradication rate (presumed plus documented) among 138 microbiologically evaluable patients was 92%. Microbiologic eradication rates (presumed plus documented) of the most common pathogens ranged from 93% (M. catarrhalis) to 100% (S. pneumoniae) at the post-therapy visit. All but one of the 265 patients who were cured or improved at post-therapy returned for a long-term follow-up visit; 243 (92%) remained well 4 to 6 weeks after therapy; and 21 (8%) had a relapse of symptoms. Adverse events considered to be related to levofloxacin administration were reported by 29 patients (9%). The most common drug-related adverse events were diarrhea, flatulence, and nausea; most adverse events were mild to moderate in severity. CONCLUSION: The results of this study indicate that levofloxacin 500 mg once daily is an effective and safe treatment for acute bacterial sinusitis.

6-(4-(1-cyclohexyl-1H-tetrazol-5-yl)butoxy)-3,4-dihydro-2(1H)-quinolinone OPC 13013 OPC-13013 Pletal cilostazol


Among various oral antiplatelets, a combination of a novel prostacyclin analogue beraprost (BPT) and a potent phosphodiesterase inhibitor cilostazol (CLZ) may result in untoward clinical effects due to possible synergistic elevation of intracellular cAMP (cyclic adenosine 3',5'-monophosphate). Thereby, a clinical study of the combined administration of the two agents was attempted. Twelve healthy volunteers were assigned to take BPT/CLZ in the following schedule; BPT: 40 micrograms at day 1 and 120 micrograms t.i.d. from day 7 to 14, CLZ: 200 mg t.i.d. from day 3 to 14. At various time intervals, physical examination and blood collection for ex vivo platelet aggregation and determination of intraplatelet cAMP were performed. Throughout the observation period, no significant alteration in vital signs was observed. Seven out of 12 subjects experienced headache of a short duration accompanying facial flush in one and nausea in one, especially after ingestion of CLZ. All of these symptoms, probably caused by the vasodilating effect of the two agents, were of mild degree and no special treatment was required. Intraplatelet cAMP content was gradually but significantly increased to 9.84 +/- 4.59 pmol per 10(9) platelets at day 14 in comparison with the initial value (6.87 +/- 2.25 pmol). The platelet aggregability was significantly suppressed at various time intervals but no additive or synergistic inhibitory effect by the combined administration was noted. In conclusion, the combined administration of BPT/CLZ is safe at doses used in the study, though the beneficial clinical effect of the combined administration has yet to be elucidated.

OBJECTIVE: A randomised, double-blind study to compare the gastrointestinal (GI) tolerability, safety and efficacy of etoricoxib and diclofenac in patients with rheumatoid arthritis (RA). PATIENTS AND METHODS: A total of 4086 patients (mean age 60.8 years) diagnosed with RA were enrolled and received etoricoxib 90 mg daily (n = 2032) or diclofenac 75 mg twice daily (n = 2054). Use of gastroprotective agents and low-dose aspirin was allowed. The prespecified primary end point consisted of the cumulative rate of patient discontinuations due to clinical and laboratory GI adverse experiences (AEs). General safety was also assessed, including adjudicated thrombotic cardiovascular event data. Efficacy was evaluated using the Patient Global Assessment of Disease Status (PGADS; 0-4 point scale). RESULTS: Mean (SD; maximum) duration of treatment was 19.3 (10.3; 32.9) and 19.1 (10.4; 33.1) months in the etoricoxib and diclofenac groups, respectively. The cumulative discontinuation rate due to GI AEs was significantly lower with etoricoxib than diclofenac (5.2 vs 8.5 events per 100 patient-years, respectively; hazard ratio 0.62 (95% CI: 0.47, 0.81; p<or=0.001)). The incidence of discontinuations for hypertension-related and oedema-related AEs were significantly higher with etoricoxib (2.5% and 1.1% respectively) compared with diclofenac (1.5% and 0.4% respectively; p<0.001 for hypertension and p<0.01 for oedema). Etoricoxib and diclofenac treatment resulted in similar efficacy (PGADS mean changes from baseline -0.62 vs -0.58, respectively). CONCLUSIONS: Etoricoxib 90 mg demonstrated a significantly lower risk for discontinuing treatment due to GI AEs compared with diclofenac 150 mg. Discontinuations from renovascular AEs, although less common than discontinuations from GI AEs, were significantly higher with etoricoxib.

Two studies evaluated quetiapine (up to 800 mg/day) in combination with a mood stabilizer (lithium or divalproex, QTP + Li/DVP) (n = 196) compared to placebo and mood stabilizer (PBO + Li/DVP) (n = 203). Extrapyramidal symptoms were evaluated using the Simpson-Angus Scale (SAS), the Barnes Akathisia Rating Scale (BARS), adverse event reports and anticholinergic drug usage. RESULTS: The incidence of EPS-related adverse events, including akathisia, was no different with quetiapine monotherapy (12.9%) than with placebo (13.1%). Similarly, EPS-related adverse events with QTP + Li/DVP (21.4%) were no different than with PBO + Li/DVP (19.2%). Adverse events related to EPS occurred in 59.6% of patients treated with haloperidol (n = 99) monotherapy, whereas 26.5% of patients treated with lithium (n = 98) monotherapy experienced adverse events related to EPS. The incidence of akathisia was low and similar with quetiapine monotherapy (3.3%) and placebo (6.1%), and with QTP + Li/DVP (3.6%) and PBO + Li/DVP (4.9%). Lithium was associated with a significantly higher incidence (p < 0.05) of tremor (18.4%) than quetiapine (5.6%); cerebellar tremor, which is a known adverse effect of lithium, may have contributed to the elevated rate of tremor in patients receiving lithium therapy. Haloperidol induced a significantly higher incidence (p < 0.001) of akathisia (33.3% versus 5.9%), tremor (30.3% versus 7.8%), and extrapyramidal syndrome (35.4% versus 5.9%) than quetiapine. No significant differences were observed between quetiapine and placebo on SAS and BARS scores. Anticholinergic use was low and similar with quetiapine or placebo. CONCLUSIONS: In bipolar mania, the incidence of EPS, including akathisia, with quetiapine therapy is similar to that with placebo.

Contribution of the sympathetic nervous system to salt-sensitivity in lifetime captopril-treated spontaneously hypertensive rats.

A potent and specific inhibitor of PEPTIDYL-DIPEPTIDASE A. It blocks the conversion of ANGIOTENSIN I to ANGIOTENSIN II, a vasoconstrictor and important regulator of arterial blood pressure. Captopril acts to suppress the RENIN-ANGIOTENSIN SYSTEM and inhibits pressure responses to exogenous angiotensin.


OBJECTIVE: To test the hypothesis that, in lifetime captopril-treated spontaneously hypertensive rats (SHR), the sympathetic nervous system contributes importantly to the hypertensive effect of dietary sodium chloride supplementation. METHODS: Male SHR (aged 6 weeks) that had been treated from conception onward with either captopril or vehicle remained on a basal sodium chloride diet or were fed a high sodium chloride diet. After 2 weeks, the rats were subjected to ganglionic blockade and 2 days later, an infusion of clonidine. RESULTS: Lifetime captopril treatment significantly lowered mean arterial pressure in both groups. Intravenous infusion of the ganglionic blocker hexamethonium resulted in a rapid decline in MAP that eliminated the dietary sodium chloride-induced increase in MAP in both groups. Infusion of the central nervous system alpha2-adrenergic receptor agonist clonidine also resulted in a greater reduction in MAP in both groups of SHR that were fed the high (compared with the basal) sodium chloride diet. CONCLUSIONS: In both lifetime captopril-treated and control SHR, the sympathetic nervous system contributes to the pressor effects of a high sodium chloride diet.

Tri-ortho-tolyl phosphate (TOTP), 360 mg/kg, po, and 0,0'-diisopropyl phosphorofluoridate (DFP), 1 mg/kg sc, were administered to adult White Leghorn chickens 24 hr after they were placed on diets containing 0 to 300 ppm corticosterone. Supplemented diets were continued until clinical signs and lesions of delayed neuropathy appeared. Although low concentrations (less than or equal to 50 ppm) of corticosterone had beneficial effects on TOTP-induced neuropathy, greater than or equal to 200 ppm exacerbated clinical signs in chickens given either TOTP or DFP. Neurotoxic esterase activities 24 hr after TOTP or DFP were less than 20% of values measured in chickens not given organophosphorous compounds. Chickens given 200 ppm corticosterone without TOTP or DFP had significantly elevated activity of plasma cholinesterase and significantly inhibited activity of liver carboxylesterase. Degenerating myelinated fibers were also evident in distal levels of the peripheral nerves of chickens given TOTP or DFP.

A 74-year-old man with depressive symptoms was admitted to a psychiatric hospital due to insomnia, loss of appetite, exhaustion, and agitation. Medical treatment was initiated at a daily dose of 20 mg paroxetine and 1.2 mg alprazolam. On the 10th day of paroxetine and alprazolam treatment, the patient exhibited marked psychomotor retardation, disorientation, and severe muscle rigidity with tremors. The patient had a fever (38.2 degrees C), fluctuating blood pressure (between 165/90 and 130/70 mg mm Hg), and severe extrapyramidal symptoms. Laboratory tests showed an elevation of creatine phosphokinase (2218 IU/L), aspartate aminotransferase (134 IU/L), alanine aminotransferase (78 IU/L), and BUN (27.9 mg/ml) levels. The patient received bromocriptine and diazepam to treat his symptoms. 7 days later, the fever disappeared and the patient's serum CPK levels were normalized (175 IU/L). This patient presented with symptoms of neuroleptic malignant syndrome (NMS), thus demonstrating that NMS-like symptoms can occur after combined paroxetine and alprazolam treatment. The adverse drug reaction score obtained by the Naranjo algorithm was 6 in our case, indicating a probable relationship between the patient's NMS-like adverse symptoms and the combined treatment used in this case. The involvement of physiologic and environmental aspects specific to this patient was suspected. Several risk factors for NMS should be noted in elderly depressive patients whose symptoms often include dehydration, agitation, malnutrition, and exhaustion. Careful therapeutic intervention is necessary in cases involving elderly patients who suffer from depression.

Acoustic Perceptual Disorder Disorders Auditory Comprehension Inattention Inattentions Processing Psychoacoustical

Acquired or developmental cognitive disorders of AUDITORY PERCEPTION characterized by a reduced ability to perceive information contained in auditory stimuli despite intact auditory pathways. Affected individuals have difficulty with speech perception, sound localization, and comprehending the meaning of inflections of speech.


Children who have status epilepticus have continuous or rapidly repeating seizures that may be life-threatening and may cause life-long changes in brain and behavior. The extent to which status epilepticus causes deficits in auditory discrimination is unknown. A naturalistic auditory location discrimination method was used to evaluate this question using an animal model of status epilepticus. Male Sprague-Dawley rats were injected with saline on postnatal day (P) 20, or a convulsant dose of pilocarpine on P20 or P45. Pilocarpine on either day induced status epilepticus; status epilepticus at P45 resulted in CA3 cell loss and spontaneous seizures, whereas P20 rats had no cell loss or spontaneous seizures. Mature rats were trained with sound-source location and sound-silence discriminations. Control (saline P20) rats acquired both discriminations immediately. In status epilepticus (P20) rats, acquisition of the sound-source location discrimination was moderately impaired. Status epilepticus (P45) rats failed to acquire either sound-source location or sound-silence discriminations. Status epilepticus in rat causes an age-dependent, long-term impairment in auditory discrimination. This impairment may explain one cause of impaired auditory location discrimination in humans.

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. (From N Engl J Med 1998 Apr 2;338(14):970-6; Neurologia 1997 Dec;12 Suppl 6:25-30)

Cardiovascular risk with cyclooxygenase inhibitors: general problem with substance specific differences?

Antagonists Prostaglandin Synthesis Cyclo Oxygenase Inhibitors Cyclo-Oxygenase Cyclooxygenase Endoperoxide Synthase Prostaglandin-Endoperoxide

Compounds or agents that combine with cyclooxygenase (PROSTAGLANDIN-ENDOPEROXIDE SYNTHASES) and thereby prevent its substrate-enzyme combination with arachidonic acid and the formation of eicosanoids, prostaglandins, and thromboxanes.


Randomised clinical trials and observational studies have shown an increased risk of myocardial infarction, stroke, hypertension and heart failure during treatment with cyclooxygenase inhibitors. Adverse cardiovascular effects occurred mainly, but not exclusively, in patients with concomitant risk factors. Cyclooxygenase inhibitors cause complex changes in renal, vascular and cardiac prostanoid profiles thereby increasing vascular resistance and fluid retention. The incidence of cardiovascular adverse events tends to increase with the daily dose and total exposure time. A comparison of individual selective and unselective cyclooxygenase inhibitors suggests substance-specific differences, which may depend on differences in pharmacokinetic parameters or inhibitory potency and may be contributed by prostaglandin-independent effects. Diagnostic markers such as N-terminal pro brain natriuretic peptide (NT-proBNP) or high-sensitive C-reactive protein might help in the early identification of patients at risk, thus avoiding the occurrence of serious cardiovascular toxicity.
