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."


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.


1. The authors examined the anticonvulsant effects of MK-801 on the pilocarpine-induced seizure model. Intraperitoneal injection of pilocarpine (400 mg/kg) induced tonic and clonic seizure. Scopolamine (10 mg/kg) and pentobarbital (5 mg/kg) prevented development of pilocarpine-induced behavioral seizure but MK-801 (0.5 mg/kg) did not. 2. An electrical seizure measured with hippocampal EEG appeared in the pilocarpine-treated group. Scopolamine and pentobarbital blocked the pilocarpine-induced electrographic seizure, MK-801 treatment augmented the electrographic seizure induced by pilocarpine. 3. Brain damage was assessed by examining the hippocampus microscopically. Pilocarpine produced neuronal death in the hippocampus, which showed pyknotic changes. Pentobarbital, scopolamine and MK-801 protected the brain damage by pilocarpine, though in the MK-801-treated group, the pyramidal cells of hippocampus appeared darker than normal. In all treatments, granule cells of the dentate gyrus were not affected. 4. These results indicate that status epilepticus induced by pilocarpine is initiated by cholinergic overstimulation and propagated by glutamatergic transmission, the elevation of which may cause brain damage through an excitatory NMDA receptor-mediated mechanism.

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.

5-Fluorouracil plus folinic acid and paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) are effective salvage therapies for metastatic breast cancer patients. Paclitaxel and 5-fluorouracil have additive cytotoxicity in MCF-7 cell lines. We performed a phase II trial of paclitaxel 175 mg/m2 over 3 hours on day I followed by folinic acid 300 mg over 1 hour before 5-fluorouracil 350 mg/m2 on days 1 to 3 every 28 days (TFL) in women with metastatic breast cancer. Analysis is reported on 37 patients with a minimum of 6 months follow-up who received a total of 192 cycles of TFL: nine cycles (5%) were associated with grade 3/4 neutropenia requiring hospitalization; seven (4%) cycles in two patients required granulocyte colony-stimulating factor due to neutropenia; no patient required platelet transfusions. Grade 3/4 nonhematologic toxicities were uncommon. Among the 34 patients evaluable for response, there were three complete responses (9%) and 18 partial responses (53%) for an overall response rate of 62%. Of the 19 evaluable patients with prior doxorubicin exposure, 11 (58%) responded compared with nine of 15 (60%) without prior doxorubicin. Plasma paclitaxel concentrations were measured at the completion of paclitaxel infusion and at 24 hours in 19 patients. TFL is an active, well-tolerated regimen in metastatic breast cancer.

Efficacy and proarrhythmia with the use of d,l-sotalol for sustained ventricular tachyarrhythmias.

Darob Knoll Pharmaceutical Brand of Sotalol MJ 1999 MJ-1999 MJ1999 Hydrochloride Monohydrochloride

An adrenergic beta-antagonist that is used in the treatment of life-threatening arrhythmias.


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).


This study prospectively evaluated the clinical efficacy, the incidence of torsades de pointes, and the presumable risk factors for torsades de pointes in patients treated with d,l-sotalol for sustained ventricular tachyarrhythmias. Eighty-one consecutive patients (54 with coronary artery disease, and 20 with dilated cardiomyopathy) with inducible sustained ventricular tachycardia or ventricular fibrillation received oral d,l-sotalol to prevent induction of the ventricular tachyarrhythmia. During oral loading with d,l-sotalol, continuous electrocardiographic (ECG) monitoring was performed. Those patients in whom d,l-sotalol prevented induction of ventricular tachycardia or ventricular fibrillation were discharged with the drug and followed up on an outpatient basis for 21 +/- 18 months. Induction of the ventricular tachyarrhythmia was prevented by oral d,l-sotalol in 35 (43%) patients; the ventricular tachyarrhythmia remained inducible in 40 (49%) patients; and two (2.5%) patients did not tolerate even 40 mg of d,l-sotalol once daily. Four (5%) patients had from torsades de pointes during the initial oral treatment with d,l-sotalol. Neither ECG [sinus-cycle length (SCL), QT or QTc interval, or U wave] nor clinical parameters identified patients at risk for torsades de pointes. However, the oral dose of d,l-sotalol was significantly lower in patients with torsades de pointes (200 +/- 46 vs. 328 +/- 53 mg/day; p = 0.0017). Risk factors associated with the development of torsades de pointes were the appearance of an U wave (p = 0.049), female gender (p = 0.015), and significant dose-corrected changes of SCL, QT interval, and QTc interval (p < 0.05). During follow-up, seven (20%) patients had a nonfatal ventricular tachycardia recurrence, and two (6%) patients died suddenly. One female patient with stable cardiac disease had recurrent torsades de pointes after 2 years of successful treatment with d,l-sotalol. Torsades de pointes occurred early during treatment even with low doses of oral d,l-sotalol. Pronounced changes in the surface ECG (cycle length, QT, and QTc) in relation to the dose of oral d,l-sotalol might identify a subgroup of patients with an increased risk for torsades de pointes. Other ECG parameters before the application of d,l-sotalol did not identify patients at increased risk for torsades de pointes. Recurrence rates of ventricular tachyarrhythmias are high despite complete suppression of the arrhythmia during programmed stimulation. Therefore programmed electrical stimulation in the case of d,l-sotalol seems to be of limited prognostic value.

A malignant form of polymorphic ventricular tachycardia that is characterized by HEART RATE between 200 and 250 beats per minute, and QRS complexes with changing amplitude and twisting of the points. The term also describes the syndrome of tachycardia with prolonged ventricular repolarization, long QT intervals exceeding 500 milliseconds or BRADYCARDIA. Torsades de pointes may be self-limited or may progress to VENTRICULAR FIBRILLATION.

Chronic hyperprolactinemia and changes in dopamine neurons.

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)


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.


The tuberoinfundibular dopaminergic (TIDA) system is known to inhibit prolactin (PRL) secretion. In young animals this system responds to acute elevations in serum PRL by increasing its activity. However, this responsiveness is lost in aging rats with chronically high serum PRL levels. The purpose of this study was to induce hyperprolactinemia in rats for extended periods of time and examine its effects on dopaminergic systems in the brain. Hyperprolactinemia was induced by treatment with haloperidol, a dopamine receptor antagonist, and Palkovits' microdissection technique in combination with high-performance liquid chromatography was used to measure neurotransmitter concentrations in several areas of the brain. After 6 months of hyperprolactinemia, dopamine (DA) concentrations in the median eminence (ME) increased by 84% over the control group. Nine months of hyperprolactinemia produced a 50% increase in DA concentrations in the ME over the control group. However, DA response was lost if a 9-month long haloperidol-induced hyperprolactinemia was followed by a 1 1/2 month-long extremely high increase in serum PRL levels produced by implantation of MMQ cells under the kidney capsule. There was no change in the levels of DA, norepinephrine (NE), serotonin (5-HT), or their metabolites in the arcuate nucleus (AN), medial preoptic area (MPA), caudate putamen (CP), substantia nigra (SN), and zona incerta (ZI), except for a decrease in 5-hydroxyindoleacetic acid (5-HIAA) in the AN after 6-months of hyperprolactinemia and an increase in DA concentrations in the AN after 9-months of hyperprolactinemia. These results demonstrate that hyperprolactinemia specifically affects TIDA neurons and these effects vary, depending on the duration and intensity of hyperprolactinemia. The age-related decrease in hypothalamic dopamine function may be associated with increases in PRL secretion.

A case of acute renal failure, due to occlusion of renal vessels in a patient with acute promyelocytic leukemia (APL) treated with all-trans-retinoic acid (ATRA) and tranexamic acid has been described recently. We report a case of acute renal failure in an APL patient treated with ATRA alone. This case further supports the concern about thromboembolic complications associated with ATRA therapy in APL patients. The patients, a 43-year-old man, presented all the signs and symptoms of APL and was included in a treatment protocol with ATRA. After 10 days of treatment, he developed acute renal failure that was completely reversible after complete remission of APL was achieved and therapy discontinued. We conclude that ATRA is a valid therapeutic choice for patients with APL, although the procoagulant tendency is not completely corrected. Thrombotic events, however, could be avoided by using low-dose heparin.

Pupillary changes associated with the development of stimulant-induced mania: a case report.

Affective Psychosis Bipolar Depression Disorder Disorders Manic Mania Manias Depressive State States Manic-Depressive Psychoses

A major affective disorder marked by severe mood swings (manic or major depressive episodes) and a tendency to remission and recurrence.


A 30-year-old cocaine-dependent man who was a subject in a study evaluating the anticraving efficacy of the stimulant medication diethylpropion (DEP) became manic during his second week on the study drug. Pupillometric changes while on DEP, especially changes in the total power of pupillary oscillation, were dramatically different than those observed in the eight other study subjects who did not become manic. The large changes in total power of pupillary oscillation occurred a few days before the patient became fully manic. Such medication-associated changes in the total power of pupillary oscillation might be of utility in identifying persons at risk for manic-like adverse effects during the medical use of psychomotor stimulants or sympathomimetic agents.

An alkaloid ester extracted from the leaves of plants including coca. It is a local anesthetic and vasoconstrictor and is clinically used for that purpose, particularly in the eye, ear, nose, and throat. It also has powerful central nervous system effects similar to the amphetamines and is a drug of abuse. Cocaine, like amphetamines, acts by multiple mechanisms on brain catecholaminergic neurons; the mechanism of its reinforcing effects is thought to involve inhibition of dopamine uptake.

OBJECTIVE: We wanted to test whether assessment of both a central pain-related signal (chemo-somatosensory evoked potential, CSSEP) and a concomitantly recorded peripheral signal (negative mucosal potential, NMP) allows for separation of central and peripheral effects of NSAIDs. For this purpose, experimental conditions were created in which NSAIDs had previously been observed to produce effects on phasic and tonic pain by either central or peripheral mechanisms. METHODS: According to a double-blind, randomised, controlled, threefold cross-over design, 18 healthy subjects (11 males, 7 females; mean age 26 years) received either placebo, 400 mg ibuprofen, or 800 mg ibuprofen. Phasic pain was applied by means of short pulses of CO2 to the nasal mucosa (stimulus duration 500 ms, interval approximately 60 s), and tonic pain was induced in the nasal cavity by means of dry air of controlled temperature, humidity and flow rate (22 degrees C, 0% relative humidity, 145 ml.s-1). Both CSSEPs as central and NMPs as peripheral correlates of pain were obtained in response to the CO2 stimuli. Additionally, the subjects rated the intensity of both phasic and tonic pain by means of visual analogue scales. RESULTS: As described earlier, administration of ibuprofen was followed by a decrease in tonic pain but-relative to placebo-an increase in correlates of phasic pain, indicating a specific effect of ibuprofen on the interaction between the pain stimuli under these special experimental conditions. Based on the similar behaviour of CSSEP and NMP, it was concluded that the pharmacological process underlying this phenomenon was localised in the periphery. By means of the simultaneous recording of interrelated peripheral and central electrophysiologic correlates of nociception, it was possible to separate central and peripheral effects of an NSAID. The major advantage of this pain model is the possibility of obtaining peripheral pain-related activity directly using a non-invasive technique in humans.

A retrospective, case-controlled analysis comparing patients admitted to a medical intensive care unit with severe exacerbations of asthma who received continuously nebulized albuterol (CNA) versus intermittent albuterol (INA) treatments is reported. Forty matched pairs of patients with asthma are compared. CNA was administered for a mean of 11 +/- 10 hr. The incidence of cardiac dysrhythmias was similar between groups. Symptomatic hypokalemia did not occur. CNA patients had higher heart rates during treatment, which may reflect severity of illness. The incidence of intubation was similar. We conclude that CNA and INA demonstrated similar profiles with regard to safety, morbidity, and mortality.

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.


A 45-year-old man, with a 10-year history of manic depression treated with lithium, was admitted with hyperosmolar, nonketotic coma. He gave a five-year history of polyuria and polydipsia, during which time urinalysis had been negative for glucose. After recovery from hyperglycaemia, he remained polyuric despite normal blood glucose concentrations; water deprivation testing indicated nephrogenic diabetes insipidus, likely to be lithium-induced. We hypothesize that when this man developed type 2 diabetes, chronic polyuria due to nephrogenic diabetes insipidus was sufficient to precipitate hyperosmolar dehydration.

Effects of the intracoronary infusion of cocaine on left ventricular systolic and diastolic function in humans.

An alkaloid ester extracted from the leaves of plants including coca. It is a local anesthetic and vasoconstrictor and is clinically used for that purpose, particularly in the eye, ear, nose, and throat. It also has powerful central nervous system effects similar to the amphetamines and is a drug of abuse. Cocaine, like amphetamines, acts by multiple mechanisms on brain catecholaminergic neurons; the mechanism of its reinforcing effects is thought to involve inhibition of dopamine uptake.


BACKGROUND: In dogs, a large amount of intravenous cocaine causes a profound deterioration of left ventricular (LV) systolic function and an increase in LV end-diastolic pressure. This study was done to assess the influence of a high intracoronary cocaine concentration on LV systolic and diastolic function in humans. METHODS AND RESULTS: In 20 patients (14 men and 6 women aged 39 to 72 years) referred for cardiac catheterization for the evaluation of chest pain, we measured heart rate, systemic arterial pressure, LV pressure and its first derivative (dP/dt), and LV volumes and ejection fraction before and during the final 2 to 3 minutes of a 15-minute intracoronary infusion of saline (n=10, control subjects) or cocaine hydrochloride 1 mg/min (n=10). No variable changed with saline. With cocaine, the drug concentration in blood obtained from the coronary sinus was 3.0+/-0.4 (mean+/-SD) mg/L, similar in magnitude to the blood cocaine concentration reported in abusers dying of cocaine intoxication. Cocaine induced no significant change in heart rate, LV dP/dt (positive or negative), or LV end-diastolic volume, but it caused an increase in systolic and mean arterial pressures, LV end-diastolic pressure, and LV end-systolic volume, as well as a decrease in LV ejection fraction. CONCLUSIONS: In humans, the intracoronary infusion of cocaine sufficient in amount to achieve a high drug concentration in coronary sinus blood causes a deterioration of LV systolic and diastolic performance.

A potent and specific HIV protease inhibitor that appears to have good oral bioavailability.


OBJECTIVE: We describe the unique CT features of ureteric calculi in six HIV-infected patients receiving indinavir, the most commonly used HIV protease inhibitor, which is associated with an increased incidence of urolithiasis. CONCLUSION: Ureteric obstruction caused by precipitated indinavir crystals may be difficult to diagnose with unenhanced CT. The calculi are not opaque, and secondary signs of obstruction may be absent or minimal and should be sought carefully. Images may need to be obtained using i.v. contrast material to enable diagnosis of ureteric stones or obstruction in patients with HIV infection who receive indinavir therapy.

51 patients with medically refractory Parkinson's disease underwent stereotactic posteromedial pallidotomy between August 1993 and February 1997 for treatment of bradykinesia, rigidity, and L-DOPA-induced dyskinesias. In 29 patients, the pallidotomies were performed with the Leksell Gamma Knife and in 22 they were performed with the standard radiofrequency (RF) method. Clinical assessment as well as blinded ratings of Unified Parkinson's Disease Rating Scale (UPDRS) scores were carried out pre- and postoperatively. Mean follow-up time is 20.6 months (range 6-48) and all except 4 patients have been followed more than one year. 85 percent of patients with dyskinesias were relieved of symptoms, regardless of whether the pallidotomies were performed with the Gamma Knife or radiofrequency methods. About 2/3 of the patients in both Gamma Knife and radiofrequency groups showed improvements in bradykinesia and rigidity, although when considered as a group neither the Gamma Knife nor the radiofrequency group showed statistically significant improvements in UPDRS scores. One patient in the Gamma Knife group (3.4%) developed a homonymous hemianopsia 9 months following treatment and 5 patients (27.7%) in the radiofrequency group became transiently confused postoperatively. No other complications were seen. Gamma Knife pallidotomy is as effective as radiofrequency pallidotomy in controlling certain of the symptoms of Parkinson's disease. It may be the only practical technique available in certain patients, such as those who take anticoagulants, have bleeding diatheses or serious systemic medical illnesses. It is a viable option for other patients as well.

A central nervous system stimulant used most commonly in the treatment of ATTENTION DEFICIT DISORDER in children and for NARCOLEPSY. Its mechanisms appear to be similar to those of DEXTROAMPHETAMINE. The d-isomer of this drug is referred to as DEXMETHYLPHENIDATE.


A 1-year-old female presented with neuroleptic malignant syndrome probably caused by methylphenidate. She had defects in the supratentorial brain including the basal ganglia and the striatum (multicystic encephalomalacia) due to severe perinatal hypoxic-ischemic encephalopathy, which was considered to be a possible predisposing factor causing neuroleptic malignant syndrome. A dopaminergic blockade mechanism generally is accepted as the pathogenesis of this syndrome. However, methylphenidate is a dopamine agonist via the inhibition of uptake of dopamine, and therefore dopaminergic systems in the brainstem (mainly the midbrain) and the spinal cord were unlikely to participate in the onset of this syndrome. A relative gamma-aminobutyric acid-ergic deficiency might occur because diazepam, a gamma-aminobutyric acid-mimetic agent, was strikingly effective. This is the first reported patient with neuroleptic malignant syndrome probably caused by methylphenidate.


Cerebromalacia Cerebromalacias Encephalomalacia Multicystic Encephalomalacias

Softening or loss of brain tissue following CEREBRAL INFARCTION; cerebral ischemia (see BRAIN ISCHEMIA), infection, CRANIOCEREBRAL TRAUMA, or other injury.

Steroid acids and salts. The primary bile acids are derived from cholesterol in the liver and usually conjugated with glycine or taurine. The secondary bile acids are further modified by bacteria in the intestine. They play an important role in the digestion and absorption of fat. They have also been used pharmacologically, especially in the treatment of gallstones.


Effects of 17alpha-ethinylestradiol (EE) on the neutral and acidic biosynthetic pathways of bile salt (BS) synthesis were evaluated in rats with an intact enterohepatic circulation and in rats with long-term bile diversion to induce BS synthesis. For this purpose, bile salt pool composition, synthesis of individual BS in vivo, hepatic activities, and expression levels of cholesterol 7alpha-hydroxylase (CYP7A), and sterol 27-hydroxylase (CYP27), as well as of other enzymes involved in BS synthesis, were analyzed in rats treated with EE (5 mg/kg, 3 days) or its vehicle. BS pool size was decreased by 27% but total BS synthesis was not affected by EE in intact rats. Synthesis of cholate was reduced by 68% in EE-treated rats, while that of chenodeoxycholate was increased by 60%. The recently identified Delta22-isomer of beta-muricholate contributed for 5.4% and 18.3 % (P < 0.01) to the pool in control and EE-treated rats, respectively, but could not be detected in bile after exhaustion of the pool. A clear reduction of BS synthesis was found in bile-diverted rats treated with EE, yet biliary BS composition was only minimally affected. Activity of CYP7A was decreased by EE in both intact and bile-diverted rats, whereas the activity of the CYP27 was not affected. Hepatic mRNA levels of CYP7A were significantly reduced by EE in bile-diverted rats only; CYP27 mRNA levels were not affected by EE. In addition, mRNA levels of sterol 12alpha-hydroxylase and lithocholate 6beta-hydroxylase were increased by bile diversion and suppressed by EE. This study shows that 17alpha-ethinylestradiol (EE)-induced intrahepatic cholestasis in rats is associated with selective inhibition of the neutral pathway of bile salt (BS) synthesis. Simultaneous impairment of other enzymes in the BS biosynthetic pathways may contribute to overall effects of EE on BS synthesis.

exendin 2 exendin-2 heliodermin helodermin


The effects of helodermin, a basic 35-amino acid peptide isolated from the venom of a lizard salivary gland, on arterial blood pressure and heart rate were examined in the rat, focusing on the possibility that activation of ATP sensitive K+ (K(ATP)) channels is involved in the responses. The results were also compared with those of vasoactive intestinal polypeptide (VIP). Helodermin produced hypotension in a dose-dependent manner with approximately similar potency and duration to VIP. Hypotension induced by both peptides was significantly attenuated by glibenclamide, which abolished a levcromakalim-produced decrease in arterial blood pressure. Oxyhemoglobin did not affect helodermin-induced hypotension, whereas it shortened the duration of acetylcholine (ACh)-produced hypotension. These findings suggest that helodermin-produced hypotension is partly attributable to the activation of glibenclamide-sensitive K+ channels (K(ATP) channels), which presumably exist on arterial smooth muscle cells. EDRF (endothelium-derived relaxing factor)/nitric oxide does not seem to play an important role in the peptide-produced hypotension.

A common genetically determined, chronic, inflammatory skin disease characterized by rounded erythematous, dry, scaling patches. The lesions have a predilection for nails, scalp, genitalia, extensor surfaces, and the lumbosacral region. Accelerated epidermopoiesis is considered to be the fundamental pathologic feature in psoriasis.


Thirteen psoriatic patients with hypertension during the course of cyclosporin A therapy were treated for 25 months with a calcium channel blocker, sustained-release nifedipine, to study the clinical antihypertensive effects and adverse events during treatment with both drugs. Seven of the 13 patients had exhibited a subclinical hypertensive state before cyclosporin A therapy. Both systolic and diastolic blood pressures of these 13 patients were decreased significantly after 4 weeks of nifedipine therapy, and blood pressure was maintained within the normal range thereafter for 25 months. The adverse events during combined therapy with cyclosporin A and nifedipine included an increase in blood urea nitrogen levels in 9 of the 13 patients and development of gingival hyperplasia in 2 of the 13 patients. Our findings indicate that sustained-release nifedipine is useful for hypertensive psoriatic patients under long-term treatment with cyclosporin A, but that these patients should be monitored for gingival hyperplasia.

Torsade de pointes ventricular tachycardia during low dose intermittent dobutamine treatment in a patient with dilated cardiomyopathy and congestive heart failure.

A malignant form of polymorphic ventricular tachycardia that is characterized by HEART RATE between 200 and 250 beats per minute, and QRS complexes with changing amplitude and twisting of the points. The term also describes the syndrome of tachycardia with prolonged ventricular repolarization, long QT intervals exceeding 500 milliseconds or BRADYCARDIA. Torsades de pointes may be self-limited or may progress to VENTRICULAR FIBRILLATION.


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).

Cardiac Failure Congestive Heart Decompensation Left Sided Left-Sided Right Right-Sided Myocardial

A heterogeneous condition in which the heart is unable to pump out sufficient blood to meet the metabolic need of the body. Heart failure can be caused by structural defects, functional abnormalities (VENTRICULAR DYSFUNCTION), or a sudden overload beyond its capacity. Chronic heart failure is more common than acute heart failure which results from sudden insult to cardiac function, such as MYOCARDIAL INFARCTION.


The authors describe the case of a 56-year-old woman with chronic, severe heart failure secondary to dilated cardiomyopathy and absence of significant ventricular arrhythmias who developed QT prolongation and torsade de pointes ventricular tachycardia during one cycle of intermittent low dose (2.5 mcg/kg per min) dobutamine. This report of torsade de pointes ventricular tachycardia during intermittent dobutamine supports the hypothesis that unpredictable fatal arrhythmias may occur even with low doses and in patients with no history of significant rhythm disturbances. The mechanisms of proarrhythmic effects of Dubutamine are discussed.


Arrhythmia Cardiac Arrhythmias Arrythmia Dysrhythmia

Any disturbances of the normal rhythmic beating of the heart or MYOCARDIAL CONTRACTION. Cardiac arrhythmias can be classified by the abnormalities in HEART RATE, disorders of electrical impulse generation, or impulse conduction.

Positive skin tests in late reactions to radiographic contrast media.

Agent Radiocontrast Agents Contrast Materials Media Radiopaque

Substances used to allow enhanced visualization of tissues.


In the last few years delayed reactions several hours after the injection of radiographic and contrast materials (PRC) have been described with increasing frequency. The authors report two observations on patients with delayed reactions in whom intradermoreactions (IDR) and patch tests to a series of ionic and non ionic PRC were studied. After angiography by the venous route in patient n degree 1 a biphasic reaction with an immediate reaction (dyspnea, loss of consciousness) and delayed macro-papular rash appeared, whilst patient n degree 2 developed a generalised sensation of heat, persistent pain at the site of injection immediately and a generalised macro-papular reaction after 24 hours. The skin tests revealed positive delayed reactions of 24 hours and 48 hours by IDR and patch tests to only some PRC with common chains in their structures. The positive skin tests are in favour of immunological reactions and may help in diagnosis of allergy in the patients.

From 1986 to 1998, 29 cancer patients who had 32 episodes of transient hyperammonemic encephalopathy related to continuous infusion of 5-fluorouracil (5-FU) were identified. None of the patients had decompensated liver disease. Onset of hyperammonemic encephalopathy varied from 0.5 to 5 days (mean: 2.6 +/- 1.3 days) after the initiation of chemotherapy. Plasma ammonium level ranged from 248 to 2387 microg% (mean: 626 +/- 431 microg%). Among the 32 episodes, 26 (81%) had various degrees of azotemia, 18 (56%) occurred during bacterial infections and 14 (44%) without infection occurred during periods of dehydration. Higher plasma ammonium levels and more rapid onset of hyperammonemia were seen in 18 patients with bacterial infections (p=0.003 and 0.0006, respectively) and in nine patients receiving high daily doses (2600 or 1800 mg/m2) of 5-FU (p=0.0001 and < 0.0001, respectively). In 25 out of 32 episodes (78%), plasma ammonium levels and mental status returned to normal within 2 days after adequate management. In conclusion, hyperammonemic encephalopathy can occur in patients receiving continuous infusion of 5-FU. Azotemia, body fluid insufficiency and bacterial infections were frequently found in these patients. It is therefore important to recognize this condition in patients receiving continuous infusion of 5-FU.

An alkaloid derived from the bark of the cinchona tree. It is used as an antimalarial drug, and is the active ingredient in extracts of the cinchona that have been used for that purpose since before 1633. Quinine is also a mild antipyretic and analgesic and has been used in common cold preparations for that purpose. It was used commonly and as a bitter and flavoring agent, and is still useful for the treatment of babesiosis. Quinine is also useful in some muscular disorders, especially nocturnal leg cramps and myotonia congenita, because of its direct effects on muscle membrane and sodium channels. The mechanisms of its antimalarial effects are not well understood.

1. The effects of two unselective potassium (K(+)-) channel blockers, quinine (12.5, 25 and 50 mg/kg) and 4-aminopyridine (1 and 2 mg/kg), on conditioned place preference and biphasic changes in motor activity induced by morphine (10 mg/kg) were tested in Wistar rats. Quinine is known to block voltage-, calcium- and ATP-sensitive K(+)-channels while 4-aminopyridine is known to block voltage-sensitive K(+)-channels. 2. In the counterbalanced method, quinine attenuated morphine-induced place preference, whereas 4-aminopyridine was ineffective. In the motor activity test measured with an Animex-activity meter neither of the K(+)-channel blockers affected morphine-induced hypoactivity, but both K(+)-channel blockers prevented morphine-induced secondary hyperactivity. 3. These results suggest the involvement of quinine-sensitive but not 4-aminopyridine-sensitive K(+)-channels in morphine reward. It is also suggested that the blockade of K(+)-channels sensitive to these blockers is not sufficient to prevent morphine-induced hypoactivity whereas morphine-induced hyperactivity seems to be connected to both quinine- and 4-aminopyridine-sensitive K(+)-channels.

1. Nociceptin, also known as orphanin FQ, is an endogenous ligand for the orphan opioid receptor-like receptor 1 (ORL1) and involves in various functions in the central nervous system (CNS). On the other hand, nocistatin is recently isolated from the same precursor as nociceptin and blocks nociceptin-induced allodynia and hyperalgesia. 2. Although ORL1 receptors which display a high degree of sequence homology with classical opioid receptors are abundant in the hippocampus, little is known regarding their role in learning and memory. 3. The present study was designed to investigate whether nociceptin/orphanin FQ and nocistatin could modulate impairment of learning and memory induced by scopolamine, a muscarinic cholinergic receptor antagonist, using spontaneous alternation of Y-maze and step-down type passive avoidance tasks in mice. 4. While nocistatin (0.5-5.0 nmol mouse-1, i.c.v.) administered 30 min before spontaneous alternation performance or the training session of the passive avoidance task, had no effect on spontaneous alternation or passive avoidance behaviours, a lower per cent alternation and shorter median step-down latency in the retention test were obtained in nociceptin (1.5 and/or 5.0 nmol mouse-1, i.c.v.)-treated normal mice. 5. Administration of nocistatin (1.5 and/or 5.0 nmol mouse-1, i.c.v.) 30 min before spontaneous alternation performance or the training session of the passive avoidance task, attenuated the scopolamine-induced impairment of spontaneous alternation and passive avoidance behaviours. 6. These results indicated that nocistatin, a new biologically active peptide, ameliorates impairments of spontaneous alternation and passive avoidance induced by scopolamine, and suggested that these peptides play opposite roles in learning and memory.

Acute Liver Injury Drug Induced Drug-Induced Disease Diseases Hepatitides Hepatitis Injuries Toxic

A spectrum of clinical liver diseases ranging from mild biochemical abnormalities to ACUTE LIVER FAILURE, caused by drugs, drug metabolites, and chemicals from the environment.


We report the case of a female patient with rheumatoid arthritis who developed acute cytolytic hepatitis due to meloxicam. Recently introduced in Belgium, meloxicam is the first nonsteroidal antiinflammatory drug with selective action on the inducible form of cyclooxygenase 2. The acute cytolytic hepatitis occurred rapidly after meloxicam administration and was associated with the development of antinuclear antibodies suggesting a hypersensitivity mechanism. This first case of meloxicam related liver toxicity demonstrates the potential of this drug to induce hepatic damage.

A form of anemia in which the bone marrow fails to produce adequate numbers of peripheral blood elements.


The antipsychotic agent, remoxipride [(S)-(-)-3-bromo-N-[(1-ethyl-2-pyrrolidinyl)methyl]-2,6-dimethoxybenz amide] has been associated with acquired aplastic anemia. We have examined the ability of remoxipride, three pyrrolidine ring metabolites and five aromatic ring metabolites of the parent compound to induce apoptosis in HL60 cells and human bone marrow progenitor (HBMP) cells. Cells were treated for 0-24 h with each compound (0-200 microM). Apoptosis was assessed by fluorescence microscopy in Hoechst 33342- and propidium iodide stained cell samples. Results were confirmed by determination of internucleosomal DNA fragmentation using gel electrophoresis for HL60 cell samples and terminal deoxynucleotidyl transferase assay in HBMP cells. The catechol and hydroquinone metabolites, NCQ436 and NCQ344, induced apoptosis in HL60 and HBMP cells in a time- and concentration dependent manner, while the phenols, NCR181, FLA873, and FLA797, and the derivatives formed by oxidation of the pyrrolidine ring, FLA838, NCM001, and NCL118, had no effect. No necrosis was observed in cells treated with NCQ436 but NCQ344 had a biphasic effect in both cell types, inducing apoptosis at lower concentrations and necrosis at higher concentrations. These data show that the catechol and hydroquinone metabolites of remoxipride have direct toxic effects in HL60 and HBMP cells, leading to apoptosis, while the phenol metabolites were inactive. Similarly, benzene-derived catechol and hydroquinone, but not phenol, induce apoptosis in HBMP cells [Moran et al., Mol. Pharmacol., 50 (1996) 610-615]. We propose that remoxipride and benzene may induce aplastic anemia via production of similar reactive metabolites and that the ability of NCQ436 and NCQ344 to induce apoptosis in HBMP cells may contribute to the mechanism underlying acquired aplastic anemia that has been associated with remoxipride.

In research towards the development of new atypical antipsychotic agents, one strategy is that the dopaminergic system can be modulated through manipulation of the serotonergic system. The synthesis and preliminary pharmacological evaluation of a series of potential atypical antipsychotic agents based on the structure of 1-(1,2-dihydro-2-acenaphthylenyl)piperazine (7) is described. Compound 7e, 5-{2-[4-(1,2-dihydro-2-acenaphthylenyl)piperazinyl]ethyl}-2,3-dihy dro-1H- indol-2-one, from this series showed significant affinities at the 5-HT1A and 5-HT2A receptors and moderate affinity at the D2 receptor. 7e exhibits a high reversal of catalepsy induced by haloperidol indicating its atypical antipsychotic nature.
