Cocaine is a risk factor for both ischemic and haemorrhagic stroke. We present the case of a 31-year-old man with bilateral ischemia of the globus pallidus after excessive alcohol and intranasal cocaine use. Drug-related globus pallidus infarctions are most often associated with heroin. Bilateral basal ganglia infarcts after the use of cocaine, without concurrent heroin use, have never been reported. In our patient, transient cardiac arrhythmia or respiratory dysfunction related to cocaine and/or ethanol use were the most likely causes of cerebral hypoperfusion.

Anterior Cerebral Circulation Infarction Brain Posterior Venous Infarctions

Tissue NECROSIS in any area of the brain, including the CEREBRAL HEMISPHERES, the CEREBELLUM, and the BRAIN STEM. Brain infarction is the result of a cascade of events initiated by inadequate blood flow through the brain that is followed by HYPOXIA and HYPOGLYCEMIA in brain tissue. Damage may be temporary, permanent, selective or pan-necrosis.

High-dose methotrexate (HD-MTX) is an important treatment for Burkitt lymphoma, but can cause hepatic and renal toxicity when its clearance is delayed. We report a case of acute renal failure after HD-MTX therapy in a patient with ileostomy, The patient was a 3-year-old boy who had received a living-related liver transplantation for congenital biliary atresia. At day 833 after the transplantation, he was diagnosed with PTLD (post-transplantation lymphoproliferative disorder, Burkitt-type malignant lymphoma). During induction therapy, he suffered ileal perforation and ileostomy was performed. Subsequent HD-MTX therapy caused acute renal failure that required continuous hemodialysis. We supposed that intravascular hypovolemia due to substantial drainage from the ileostoma caused acute prerenal failure. After recovery of his renal function, we could safely treat the patient with HD-MTX therapy by controlling drainage from ileostoma with total parenteral nutrition.


African Lymphoma Burkitt Cell Leukemia Tumor Burkitt's Burkitts L3 Lymphocytic Leukemias Lymphoblastic Burkitt-Type

A form of undifferentiated malignant LYMPHOMA usually found in central Africa, but also reported in other parts of the world. It is commonly manifested as a large osteolytic lesion in the jaw or as an abdominal mass. B-cell antigens are expressed on the immature cells that make up the tumor in virtually all cases of Burkitt lymphoma. The Epstein-Barr virus (HERPESVIRUS 4, HUMAN) has been isolated from Burkitt lymphoma cases in Africa and it is implicated as the causative agent in these cases; however, most non-African cases are EBV-negative.

Antithrombotic drug use, cerebral microbleeds, and intracerebral hemorrhage: a systematic review of published and unpublished studies.

Brain Hemorrhage Cerebral Hemorrhages Parenchymal Cerebrum Intracerebral

Bleeding into one or both CEREBRAL HEMISPHERES including the BASAL GANGLIA and the CEREBRAL CORTEX. It is often associated with HYPERTENSION and CRANIOCEREBRAL TRAUMA.


BACKGROUND AND PURPOSE: Cerebral microbleeds (MB) are potential risk factors for intracerebral hemorrhage (ICH), but it is unclear if they are a contraindication to using antithrombotic drugs. Insights could be gained by pooling data on MB frequency stratified by antithrombotic use in cohorts with ICH and ischemic stroke (IS)/transient ischemic attack (TIA). METHODS: We performed a systematic review of published and unpublished data from cohorts with stroke or TIA to compare the presence of MB in: (1) antithrombotic users vs nonantithrombotic users with ICH; (2) antithrombotic users vs nonusers with IS/TIA; and (3) ICH vs ischemic events stratified by antithrombotic use. We also analyzed published and unpublished follow-up data to determine the risk of ICH in antithrombotic users with MB. RESULTS: In a pooled analysis of 1460 ICH and 3817 IS/TIA, MB were more frequent in ICH vs IS/TIA in all treatment groups, but the excess increased from 2.8 (odds ratio; range, 2.3-3.5) in nonantithrombotic users to 5.7 (range, 3.4-9.7) in antiplatelet users and 8.0 (range, 3.5-17.8) in warfarin users (P difference=0.01). There was also an excess of MB in warfarin users vs nonusers with ICH (OR, 2.7; 95% CI, 1.6-4.4; P<0.001) but none in warfarin users with IS/TIA (OR, 1.3; 95% CI, 0.9-1.7; P=0.33; P difference=0.01). There was a smaller excess of MB in antiplatelet users vs nonusers with ICH (OR, 1.7; 95% CI, 1.3-2.3; P<0.001), but findings were similar for antiplatelet users with IS/TIA (OR, 1.4; 95% CI, 1.2-1.7; P<0.001; P difference=0.25). In pooled follow-up data for 768 antithrombotic users, presence of MB at baseline was associated with a substantially increased risk of subsequent ICH (OR, 12.1; 95% CI, 3.4-42.5; P<0.001). CONCLUSIONS: The excess of MB in warfarin users with ICH compared to other groups suggests that MB increase the risk of warfarin-associated ICH. Limited prospective data corroborate these findings, but larger prospective studies are urgently required.


Anterior Choroidal Artery Infarction Cerebral Left Hemisphere Right Infarctions Subcortical Posterior

The formation of an area of NECROSIS in the CEREBRUM caused by an insufficiency of arterial or venous blood flow. Infarcts of the cerebrum are generally classified by hemisphere (i.e., left vs. right), lobe (e.g., frontal lobe infarction), arterial distribution (e.g., INFARCTION, ANTERIOR CEREBRAL ARTERY), and etiology (e.g., embolic infarction).

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)


AIM: Verapamil stimulation test was previously investigated as a tool for differential diagnosis of hyperprolactinemia, but with conflicting results. Macroprolactinemia was never considered in those previous studies. Here, we aimed to re-investigate the diagnostic value of verapamil in a population who were all screened for macroprolactinemia. Prolactin responses to verapamil in 65 female patients (age: 29.9 +/- 8.1 years) with hyperprolactinemia were tested in a descriptive, matched case-control study. METHODS: Verapamil 80 mg, p.o. was administered, and then PRL levels were measured at 8th and 16th hours, by immunometric chemiluminescence. Verapamil responsiveness was determined by peak percent change in basal prolactin levels (PRL). RESULTS: Verapamil significantly increased PRL levels in healthy controls (N. 8, PRL: 183%), macroprolactinoma (N. 8, PRL: 7%), microprolactinoma (N. 19, PRL: 21%), macroprolactinemia (N. 23, PRL: 126%), but not in pseudoprolactinoma (N. 8, PRL: 0.8%), and risperidone-induced hyperprolactinemia (N. 7, PRL: 3%). ROC curve analysis revealed that unresponsiveness to verapamil defined as PRL <7%, discriminated anatomical or functional stalk effect (sensitivity: 74%, specificity: 73%, AUC: 0.855+/-0.04, P <0.001, CI: 0.768-0.942) associated with pseudoprolactinoma or risperidone-induced hyperprolactinemia, respectively. CONCLUSION: Verapamil responsiveness is not a reliable finding for the differential diagnosis of hyperprolactinemia. However, verapamil unresponsiveness discriminates stalk effect (i.e., anatomically or functionally inhibited dopaminergic tonus) from other causes of hyperprolactinemia with varying degrees of responsiveness.

The effect of clonidine, naphazoline and xylometazoline on analgesia induced by morphine, codeine, fentanyl and pentazocine, and on cataleptic effect of morphine, codine and fentanyl was studied in rats. The biochemical assays on the influence of four analgesics on the brain concentration and turnover of noradrenaline (NA) were also performed. It was found that three drugs stimulating central NA receptors failed to affect the analgesic ED50 of all antinociceptive agents and they enhanced catalepsy induced by morphine and fentanyl. Codeine catalepsy was increased by clonidine and decreased by naphazoline and xylometazoline. The brain concentration of NA was not changed by morphine and fentanyl, but one of the doses of codeine (45 mg/kg) slightly enhanced it. Pentazocine dose-dependently decreased the brain level of NA. The rate of NA turnover was not altered by analgesics except for the higher dose of fentanyl (0.2 mg/kg) following which the disappearance of NA from the brain was diminished. The results are discussed in the light of various and non-uniform data from the literature. It is suggested that in rats the brain NA plays a less important function than the other monoamines in the behavioural activity of potent analgesics.

A widely used non-cardioselective beta-adrenergic antagonist. Propranolol has been used for MYOCARDIAL INFARCTION; ARRHYTHMIA; ANGINA PECTORIS; HYPERTENSION; HYPERTHYROIDISM; MIGRAINE; PHEOCHROMOCYTOMA; and ANXIETY but adverse effects instigate replacement by newer drugs.


Fasting Hypoglycemia Postabsorptive Postprandial Reactive

A syndrome of abnormally low BLOOD GLUCOSE level. Clinical hypoglycemia has diverse etiologies. Severe hypoglycemia eventually lead to glucose deprivation of the CENTRAL NERVOUS SYSTEM resulting in HUNGER; SWEATING; PARESTHESIA; impaired mental function; SEIZURES; COMA; and even DEATH.


The cardiovascular effects of hypoglycaemia, with and without beta-blockade, were compared in fourteen healthy men. Eight received insulin alone, and eight, including two of the original insulin-only group, were given propranolol and insulin. In the insulin-group the period of hypoglycaemia was associated with an increase in heart-rate and a fall in diastolic blood-pressure. In the propranolol-insulin group there was a significant fall in heart-rate in most subjects and an increase in diastolic pressure. Typical S-T/T changes occurred in the insulin-group but in none of the propranolol-insulin group. Hypertension in diabetics prone to hypoglycaemia attacks should not be treated with beta-blockers because these drugs may cause a sharp rise in blood-pressure in such patients.

Prevention and treatment of endometrial disease in climacteric women receiving oestrogen therapy.

Pathological processes involving any part of the UTERUS.


Agents Estrogenic Agonists Estrogen Receptor Compounds Effects Effect Estrogens

Compounds that interact with ESTROGEN RECEPTORS in target tissues to bring about the effects similar to those of ESTRADIOL. Estrogens stimulate the female reproductive organs, and the development of secondary female SEX CHARACTERISTICS. Estrogenic chemicals include natural, synthetic, steroidal, or non-steroidal compounds.


The treatment regimens are described in 74 patients with endometrial disease among 850 climacteric women receiving oestrogen therapy. Cystic hyperplasia was associated with unopposed oestrogen therapy without progestagen. Two courses of 21 days of 5 mg norethisterone daily caused reversion to normal in all 57 cases of cystic hyperplasia and 6 of the 8 cases of atypical hyperplasia. 4 cases of endometrial carcinoma referred from elsewhere demonstrated the problems of inappropriate and unsupervised unopposed oestrogen therapy and the difficulty in distinguishing severe hyperplasia from malignancy. Cyclical low-dose oestrogen therapy with 7--13 days of progestagen does not seem to increase the risk of endometrial hyperplasia or carcinoma.

5,5-Diphenylhydantoin Antisacer Difenin Dihydan Dilantin Diphenylhydantoin Diphenylhydantoinate Sodium Epamin Epanutin Fenitoin Hydantol Park Davis brand of Phenytoin Pfizer Brand Phizer

An anticonvulsant that is used to treat a wide variety of seizures. It is also an anti-arrhythmic and a muscle relaxant. The mechanism of therapeutic action is not clear, although several cellular actions have been described including effects on ion channels, active transport, and general membrane stabilization. The mechanism of its muscle relaxant effect appears to involve a reduction in the sensitivity of muscle spindles to stretch. Phenytoin has been proposed for several other therapeutic uses, but its use has been limited by its many adverse effects and interactions with other drugs.


A patient taking diphenylhydantoin for 3 weeks developed a generalized skin rash, lymphadenopathy and pure red cell aplasia. After withdrawal of the pharmacon all symptoms disappeared spontaneously. Skin rash is a well-known complication of diphenylhydantoin treatment as is benign and malignant lymphadenopathy. Pure red cell aplasia associated with diphenylhydantoin medication has been reported in 3 patients. The exact mechanism by which diphenylhydantoin exerts its toxic effects is not known. In this patient the time relation between the ingestion of diphenylhydantoin and the occurrence of the skin rash, lymphadenopathy and pure red cell aplasia is very suggestive of a direct connection.


Diseases in which skin eruptions or rashes are a prominent manifestation. Classically, six such diseases were described with similar rashes; they were numbered in the order in which they were reported. Only the fourth (Duke's disease), fifth (ERYTHEMA INFECTIOSUM), and sixth (EXANTHEMA SUBITUM) numeric designations survive as occasional synonyms in current terminology.

Invasion of the host organism by microorganisms that can cause pathological conditions or diseases.


The cure rate of infections in cancer patients is adversely affected by neutropenia (less than 1,000/mm3). In particular, patients with severe neutropenia (less than 100/mm3) have shown a poor response to antibiotics. To overcome the adverse effects of neutropenia, tobramycin was given by continuous infusion and combined with intermittent carbenicillin. Tobramycin was given to a total daily dose of 300 mg/m2 and carbenicillin was given at a dose of 5 gm every four hours. There were 125 infectious episodes in 116 cancer patients receiving myelosuppressive chemotherapy. The overall cure rate was 70%. Pneumonia was the most common infection and 61% of 59 episodes were cured. Gram-negative bacilli were the most common causative organisms and 69% of these infections were cured. The most common pathogen was Klebsiella pneumoniae and this, together with Escherichia coli and Pseudomonas aeruginosa, accounted for 74% of all gram-negative bacillary infections. Response was not influenced by the initial neutrophil count, with a 62% cure rate for 39 episodes associated with severe neutropenia. However, failure of the neutrophil count to increase during therapy adversely affected response. Azotemia was the major side effect recognized, and it occurred in 11% of episodes. Major azotemia (serum creatinine greater than 2.5 mg/dl or BUN greater than 50 mg/dl) occurred in only 2%. Azotemia was not related to duration of therapy or serum tobramycin concentration. This antibiotic regimen showed both therapeutic efficacy and acceptable renal toxicity for these patients.

Aneurysmal Subarachnoid Hemorrhage Hemorrhages Intracranial Perinatal Spontaneous SAH (Subarachnoid Hemorrhage) SAHs

Bleeding into the intracranial or spinal SUBARACHNOID SPACE, most resulting from INTRACRANIAL ANEURYSM rupture. It can occur after traumatic injuries (SUBARACHNOID HEMORRHAGE, TRAUMATIC). Clinical features include HEADACHE; NAUSEA; VOMITING, nuchal rigidity, variable neurological deficits and reduced mental status.


Acid Derivatives Aminocaproic Aminohexanoic Acids Aminocaproates Aminohexanoates

Amino derivatives of caproic acid. Included under this heading are a broad variety of acid forms, salts, esters, and amides that contain the amino caproic acid structure.


Epsilon aminocaproic acid (EACA) has been used to prevent rebleeding in patients with subarachnoid hemorrhage (SAH). Although this agent does decrease the frequency of rebleeding, several reports have described thrombotic complications of EACA therapy. These complications have included clinical deterioration and intracranial vascular thrombosis in patients with SAH, arteriolar and capillary fibrin thrombi in patients with fibrinolytic syndromes treated with EACA, or other thromboembolic phenomena. Since intravascular fibrin thrombi are often observed in patients with fibrinolytic disorders, EACA should not be implicated in the pathogenesis of fibrin thrombi in patients with disseminated intravascular coagulation or other "consumption coagulopathies." This report describes subtotal infarction of the kidney due to thrombosis of a normal renal artery. This occlusion occurred after EACA therapy in a patient with SAH and histopathological documentation of recurrent SAH. The corresponding clinical event was characterized by marked hypertension and abrupt neurological deterioration.

AY 20694 AY-20694 AY20694 Anaprilin Anapriline Avlocardyl Betadren Dexpropranolol Dociton Hydrochloride Propranolol Inderal Obsidan Obzidan Propanolol Rexigen

A widely used non-cardioselective beta-adrenergic antagonist. Propranolol has been used for MYOCARDIAL INFARCTION; ARRHYTHMIA; ANGINA PECTORIS; HYPERTENSION; HYPERTHYROIDISM; MIGRAINE; PHEOCHROMOCYTOMA; and ANXIETY but adverse effects instigate replacement by newer drugs.


Propranolol, a beta-adrenergic blocking agent, has found an important position in the practice of medicine. Its use in pregnancy, however, is an open question as a number of detrimental side effects have been reported in the fetus and neonate. Ten patients and 12 pregnancies are reported where chronic propranolol has been administered. Five patients with serial pregnancies with and without propranolol therapy are also examined. Maternal, fetal, and neonatal complications are examined. An attempt is made to differentiate drug-related complications from maternal disease--related complications. We conclude that previously reported hypoglycemia, hyperbilirubinemia, polycythemia, neonatal apnea, and bradycardia are not invariable and cannot be statistically correlated with chronic propranolol therapy. Growth retardation, however, appears to be significant in both of our series.


Fasting Hypoglycemia Postabsorptive Postprandial Reactive

A syndrome of abnormally low BLOOD GLUCOSE level. Clinical hypoglycemia has diverse etiologies. Severe hypoglycemia eventually lead to glucose deprivation of the CENTRAL NERVOUS SYSTEM resulting in HUNGER; SWEATING; PARESTHESIA; impaired mental function; SEIZURES; COMA; and even DEATH.


Bilirubinemia Bilirubinemias Hyperbilirubinemia Hyperbilirubinemias

Use of propranolol in the treatment of idiopathic orthostatic hypotension.


Five patients with idiopathic orthostatic hypotension who had physiologic and biochemical evidence of severe autonomic dysfunction were included in the study. They all exhibited markedly reduced plasma catecholamines and plasma renin activity in both recumbent and upright positions and had marked hypersensitivity to the pressor effects of infused norepinephrine. Treatment with propanolol administered intravenously (1-5 mg) produced increases in supine and upright blood pressure in 4 of the 5 individuals with rises ranging from 11/6 to 22/11 mmHg. Chronic oral administration of propranolol (40-160 mg/day) also elevated the blood pressures of these individuals with increases in the order of 20-35/15-25 mmg being observed. In 1 patient, marked hypertension was induced by propranolol and the drug had to be withdrawn. It otherwise was well tolerated and no important side effects were observed. Treatment has been continued in 3 individuals for 6-13 months with persistence of the pressor effect, although there appears to have been some decrease in the degree of response with time. Hemodynamic measurements in 1 of the patients demonstrated an increase in total peripheral resistance and essentially no change in cardiac output following propranolol therapy. The studies suggest that propranolol is a useful drug in selected patients with severe idiopathic orthostatic hypotension.

Total intravenous anesthesia with etomidate. III. Some observations in adults.

Ethomidate Etomidate Hypnomidate R 26490 R-26490 R26490 Radenarkon

Imidazole derivative anesthetic and hypnotic with little effect on blood gases, ventilation, or the cardiovascular system. It has been proposed as an induction anesthetic.


An investigation was undertaken to determine the dosage of etomidate required to maintain sleep in adults undergoing surgery under regional local anesthesia. Premedication of diazepam 10 mg and atropine 0.5 mg was given, and sleep was induced and maintained by intermittent intravenous injections of etomidate 0.1/mg/kg, given whenever the patient would open his eyes on request. A mean overall dose of etomidate 17.4 microgram/kg/min. was required to maintain sleep, but great individual variation occurred, with older patients requiring less drug. The investigation was discontinued after 18 patients because of the frequency and intensity of side-effects, particularly pain and myoclonia, which caused the technique to be abandoned in two cases. It is considered unlikely that etomidate will prove to be the hypnotic of choice for a totally intravenous anesthetic technique in adults because of the high incidence of myoclonia after prolonged administration. In several patients uncontrollable muscle movements persisted for many minutes after complete recovery of consciousness.

A method for the measurement of tremor, and a comparison of the effects of tocolytic beta-mimetics.

Action Tremor Tremors Coarse Continuous Darkness Fine Intention Intermittent Involuntary Quiver Quivers Limb Massive Muscle Neonatal Nerve Passive Perioral Persistent Pill Rolling Rest Resting Saturnine Semirhythmic Senile Static

Cyclical movement of a body part that can represent either a physiologic process or a manifestation of disease. Intention or action tremor, a common manifestation of CEREBELLAR DISEASES, is aggravated by movement. In contrast, resting tremor is maximal when there is no attempt at voluntary movement, and occurs as a relatively frequent manifestation of PARKINSON DISEASE.


A method permitting measurement of finger tremor as a displacement-time curve is described, using a test system with simple amplitude calibration. The coordinates of the inversion points of the displacement-time curves were transferred through graphical input equipment to punched tape. By means of a computer program, periods and amplitudes of tremor oscillations were calculated and classified. The event frequency for each class of periods and amplitudes was determined. The actions of fenoterol-hydrobromide, ritodrin-HCl and placebo given to 10 healthy subjects by intravenous infusion in a double-blind crossover study were tested by this method. At therapeutic doses both substances raised the mean tremor amplitude to about three times the control level. At the same time, the mean period within each class of amplitudes shortened by 10--20 ms, whereas the mean periods calculated from all oscillations together did not change significantly. After the end of fenoterol-hydrobromide infusion, tremor amplitudes decreased significantly faster than those following ritodrin-HCl infusion.

Cefalotin Cefalotina Normon Sodica Spaly Ceftina Cephalothin Monosodium Salt Sodium Galen Brand of Keflin Lilly Seffin


Acquired Hemolytic Anemia Microangiopathic

A condition of inadequate circulating red blood cells (ANEMIA) or insufficient HEMOGLOBIN due to premature destruction of red blood cells (ERYTHROCYTES).


A patient with renal disease developed Coombs-positive hemolytic anemia while receiving cephalothin therapy. An anti-cephalothin IgG antibody was detected in the patient's serum and in the eluates from her erythrocytes. In addition, nonimmunologic binding of normal and patient's serum proteins to her own and cephalothin-coated normal red cells was demonstrated. Skin tests and in vitro lymphocyte stimulation revealed that the patient was sensitized to cephalothin and also to ampicillin. Careful investigation of drug-induced hemolytic anemias reveals the complexity of the immune mechanisms involved.

Idiopathic Parkinson Disease Parkinson's Lewy Body Paralysis Agitans Parkinsonism Primary

A progressive, degenerative neurologic disease characterized by a TREMOR that is maximal at rest, retropulsion (i.e. a tendency to fall backwards), rigidity, stooped posture, slowness of voluntary movements, and a masklike facial expression. Pathologic features include loss of melanin containing neurons in the substantia nigra and other pigmented nuclei of the brainstem. LEWY BODIES are present in the substantia nigra and locus coeruleus but may also be found in a related condition (LEWY BODY DISEASE, DIFFUSE) characterized by dementia in combination with varying degrees of parkinsonism. (Adams et al., Principles of Neurology, 6th ed, p1059, pp1067-75)


Hypokalemia, sometimes severe, was observed in some L-dopa-treated parkinsonian patients. The influence of L-dopa on the renal excretion of potassium was studied in 3 patients with hypokalemia and in 5 normokalemic patients by determination of renal plasma flow, glomerular filtration rate, plasma concentration of potassium and sodium as well as urinary excretion of potassium, sodium and aldosterone. L-Dopa intake was found to cause an increased excretion of potassium, and sometimes also of sodium, in the hypokalemic but not in the normokalemic patients. This effect on the renal function could be prohibited by the administration of a peripheral dopa decarbodylase inhibitor. It is not known why this effect occurred in some individuals but not in others, but our results indicate a correlation between aldosterone production and this renal effect of L-dopa.

Hypokalemia Hypokalemias Hypopotassemia Hypopotassemias

Phenytoin encephalopathy as probable idiosyncratic reaction: case report.

5,5-Diphenylhydantoin Antisacer Difenin Dihydan Dilantin Diphenylhydantoin Diphenylhydantoinate Sodium Epamin Epanutin Fenitoin Hydantol Park Davis brand of Phenytoin Pfizer Brand Phizer

An anticonvulsant that is used to treat a wide variety of seizures. It is also an anti-arrhythmic and a muscle relaxant. The mechanism of therapeutic action is not clear, although several cellular actions have been described including effects on ion channels, active transport, and general membrane stabilization. The mechanism of its muscle relaxant effect appears to involve a reduction in the sensitivity of muscle spindles to stretch. Phenytoin has been proposed for several other therapeutic uses, but its use has been limited by its many adverse effects and interactions with other drugs.


Brain Disease Diseases Disorder Disorders CNS Intracranial Central Nervous System Encephalon

Pathologic conditions affecting the BRAIN, which is composed of the intracranial components of the CENTRAL NERVOUS SYSTEM. This includes (but is not limited to) the CEREBRAL CORTEX; intracranial white matter; BASAL GANGLIA; THALAMUS; HYPOTHALAMUS; BRAIN STEM; and CEREBELLUM.


A case of phenytoin (DPH) encephalopathy with increasing seizures and EEG and mental changes is described. Despite adequate oral dosage of DPH (5 mg/kg/daily) the plasma level was very low (2.8 microgramg/ml). The encephalopathy was probably an idiosyncratic and not toxic or allergic reaction. In fact the concentration of free DPH was normal, the patient presented a retarded morbilliform rash during DPH treatment, the protidogram was normal, and an intradermic DPH injection had no local effect. The authors conclude that in a patient starting DPH treatment an unexpected increase in seizures, with EEG and mental changes occurring simultaneously, should alert the physician to the possible need for eliminating DPH from the therapeutic regimen, even if plasma concentrations are low.

NECROSIS of the MYOCARDIUM caused by an obstruction of the blood supply to the heart (CORONARY CIRCULATION).


The effect of exercise on the severity of isoproterenol-induced myocardial infarction was studied in male rats. Ninety-three rats were randomly divided into three groups. The exercise-isoproterenol (E-1) and exercise control (EC) groups exercised daily for thirty days on a treadmill at 1 mph, 2% grade while animals of the sedentary-isoproterenol (S-I) group remained sedentary. Eight animals were assigned to the sedentary control (SC) group which remained sedentary throughout the experimental period. Forty-eight hours after the final exercise period, S-I and E-I animals received a single subcutaneous injection of isoproterenol (250 mg/kg body weight). Animals of the S-I group exhibited significantly (Pp less than 0.05) greater mortality from the effects of isoproterenol than animals of the E-I group. Serum CPK activity for E-I animals was significantly (p less than 0.05) greater than for animals in the S-I and EC groups twenty hours following isoproterenol injection. No statistically significant differences were observed between the two isoproterenol treated groups for severity of the induced lesions, changes in heart weight, or heart weight to body weight ratios. The results indicated that exercise reduced the mortality associated with the effects of large dosages of isoproterenol but had little on the severity of the infarction.

Effect of D-Glucarates on basic antibiotic-induced renal damage in rats.

A sugar acid derived from D-glucose in which both the aldehydic carbon atom and the carbon atom bearing the primary hydroxyl group are oxidized to carboxylic acid groups.


Dehydrated rats regularly develop acute renal failure following single injection of aminoglycoside antibiotics combined with dextran or of antibiotics only. Oral administration of 2,5-di-O-acetyl-D-glucaro-1,4-6,3-dilactone protected rats against renal failure induced by kanamycin-dextran. The protective effect was prevalent among D-glucarates, and also to other saccharic acid, hexauronic acids and hexaaldonic acids, although to a lesser degree, but not to a hexaaldose, sugar alcohols, substances inthe TCA cycle and other acidic compounds. D-Glucarates were effective against renal damage induced by peptide antibiotics as well as various aminoglycoside antibitocis. Dose-responses were observed in the protective effect of D-Glucarates. With a D-glucarate of a fixed size of dose, approximately the same degree of protection was obtained against renal damages induced by different basic antibiotics despite large disparities in administration doses of different antibiotics. D-Glucarates had the ability to prevent renal damage but not to cure it. Rats excreted acidic urine when they were spared from renal lesions by monosaccharides. The reduction effect of D-glucarates against nephrotoxicity of basic antibiotics was discussed.

An antineoplastic antimetabolite with immunosuppressant properties. It is an inhibitor of TETRAHYDROFOLATE DEHYDROGENASE and prevents the formation of tetrahydrofolate, necessary for synthesis of thymidylate, an essential component of DNA.


A patient who developed paraplegia following the intrathecal instillation of methotrexate is discribed. The ten previously reported cases of this unusual complication are reviewed. The following factors appear to predispose to the development of this complication: abnormal cerebrospinal dynamics related to the presence of central nervous system leukemia, and epidural cerebrospinal leakage; elevated cerebrospinal fluid methothexate concentration related to abnormal cerebrospinal fluid dynamics and to inappropriately high methotrexate doses based on body surface area calculations in older children and adults; the presence of neurotoxic preservatives in commercially available methotrexate preparations and diluents; and the use of methotrexate diluents of unphysiologic pH, ionic content and osmolarity. The role of methotrexate contaminants, local folate deficiency, and cranial irradiation in the pathogenesis of intrathecal methotrexate toxicity is unclear. The incidence of neurotoxicity may be reduced by employing lower doses of methotrexate in the presence of central nervous system leukemia, in older children and adults, and in the presence of epidural leakage. Only preservative-free methotrexate in Elliott's B Solution at a concentration of not more than 1 mg/ml should be used for intrathecal administration. Periodic monitoring of cerebruspinal fluid methotrexate levels may be predictive of the development of serious neurotoxicity.

A slowly hydrolyzed cholinergic agonist that acts at both muscarinic and nicotinic receptors.


The pressor response to the intracisternal (i.c.) injection of carbachol (1 mug) in anesthetized rats was analyzed. This response was significantly reduced by the intravenous (i.v.) injection of guanethidine (5 mg), hexamethonium (10 mg) or phentolamine (5 mg), and conversely, potentiated by i.v. desmethylimipramine (0.3 mg), while propranolol (0.5 mg) i.v. selectively inhibited the enlargement of pulse pressure and the tachycardia following i.c. carbachol (1 mug). On the other hand, the pressor response to i.c. carbachol (1 mug) was almost completely blocked by i.c. atropine (3 mug) or hexamethonium (500 mug), and significantly reduced by i.c. chlorpromazine (50 mug) but significantly potentiated by i.c. desmethylimipramine (30 mug). The pressor response to i.c. carbachol (1 mug) remained unchanged after sectioning of the bilateral cervical vagal nerves but disappeared after sectioning of the spinal cord (C7-C8). From the above result it is suggested that the pressor response to i.c. carbachol ortral and peripheral adrenergic mechanisms, and that the sympathetic trunk is the main pathway.

4 Epitetracycline 4-Epitetracycline Achromycin V Hostacyclin Sustamycin Tetrabid Tetracycline Hydrochloride Monohydrochloride Topicycline

A naphthacene antibiotic that inhibits AMINO ACYL TRNA binding during protein synthesis.


Dose-response relationships, biochemical mechanisms, and sex differences in the experimental fatty liver induced by tetracycline were studied in the intact rat and with the isolated perfused rat liver in vitro. In the intact male and female rat, no direct relationship was observed between dose of tetracycline and hepatic accumulation of triglyceride. With provision of adequate oleic acid as a substrate for the isolated perfused liver, a direct relationship was observed between dose of tetracycline and both accumulation of triglyceride in the liver and depression of output of triglyceride by livers from male and female rats. Marked differences were observed between female and male rats with regard to base line (control) hepatic concentration of triglyceride and output of triglyceride. Accumulation of hepatic triglyceride, as a per cent of control values, in response to graded doses of tetracycline, did not differ significantly between male, female and pregnant rat livers. However, livers from female, and especially pregnant female rats, were strikingly resistant to the effects of tetracycline on depression of output of triglyceride under these experimental conditions. These differences between the sexes could not be related to altered disposition of tetracycline or altered uptake of oleic acid. Depressed hepatic secretion of triglyceride accounted only for 30 to 50% of accumulated hepatic triglyceride, indicating that additional mechanisms must be involved in the production of the triglyceride-rich fatty liver in response to tetracycline.

(From AMA Drug Evaluations Annual, 1994, p236)


The effects of progesterone treatment on bupivacaine arrhythmogenicity in beating rat heart myocyte cultures and on anesthetized rats were determined. After determining the bupivacaine AD50 (the concentration of bupivacaine that caused 50% of all beating rat heart myocyte cultures to become arrhythmic), we determined the effect of 1-hour progesterone HCl exposure on myocyte contractile rhythm. Each concentration of progesterone (6.25, 12.5, 25, and 50 micrograms/ml) caused a significant and concentration-dependent reduction in the AD50 for bupivacaine. Estradiol treatment also increased the arrhythmogenicity of bupivacaine in myocyte cultures, but was only one fourth as potent as progesterone. Neither progesterone nor estradiol effects on bupivacaine arrhythmogenicity were potentiated by epinephrine. Chronic progesterone pretreatment (5 mg/kg/day for 21 days) caused a significant increase in bupivacaine arrhythmogenicity in intact pentobarbital-anesthetized rats. There was a significant decrease in the time to onset of arrhythmia as compared with control nonprogesterone-treated rats (6.2 +/- 1.3 vs. 30.8 +/- 2.5 min, mean +/- SE). The results of this study indicate that progesterone can potentiate bupivacaine arrhythmogenicity both in vivo and in vitro. Potentiation of bupivacaine arrhythmia in myocyte cultures suggests that this effect is at least partly mediated at the myocyte level.

Natural product isolated from Streptomyces pilosus. It forms iron complexes and is used as a chelating agent, particularly in the mesylate form.


A patient with transfusion-dependent thalassemia was undergoing home intravenous desferrioxamine (DFX) treatment by means of a totally implanted system because of his poor compliance with the nightly subcutaneous therapy. Due to an accidental malfunctioning of the infusion pump, the patient was inadvertently administered a toxic dosage of the drug which caused renal insufficiency. Given the progressive deterioration of the symptoms and of the laboratory values, despite adequate medical treatment, a decision was made to introduce haemodialytical therapy in order to remove the drug and therapy reduce the nephrotoxicity. From the results obtained, haemodialysis can therefore be suggested as a useful therapy in rare cases of progressive acute renal failure caused by desferrioxamine.

Neuroleptic-associated hyperprolactinemia. Can it be treated with bromocriptine?

Agents Antipsychotic Major Tranquilizing Tranquillizing Neuroleptic Drugs Effect Effects Antipsychotics Tranquilizers Neuroleptics

Agents that control agitated psychotic behavior, alleviate acute psychotic states, reduce psychotic symptoms, and exert a quieting effect. They are used in SCHIZOPHRENIA; senile dementia; transient psychosis following surgery; or MYOCARDIAL INFARCTION; etc. These drugs are often referred to as neuroleptics alluding to the tendency to produce neurological side effects, but not all antipsychotics are likely to produce such effects. Many of these drugs may also be effective against nausea, emesis, and pruritus.


Hyperprolactinaemia Hyperprolactinemia Hyperprolactinemias Hypersecretion Syndrome Prolactin Inappropriate Secretion

A semisynthetic ergotamine alkaloid that is a dopamine D2 agonist. It suppresses prolactin secretion.


Six stable psychiatric outpatients with hyperprolactinemia and amenorrhea/oligomenorrhea associated with their neuroleptic medications were treated with bromocriptine. Daily dosages of 5-10 mg corrected the hyperprolactinemia and restored menstruation in four of the six patients. One woman, however, developed worsened psychiatric symptoms while taking bromocriptine, and it was discontinued. Thus, three of six patients had their menstrual irregularity successfully corrected with bromocriptine. This suggests that bromocriptine should be further evaluated as potential therapy for neuroleptic-associated hyperprolactinemia and amenorrhea/galactorrhea.

Intracerebroventricular injection of ethacrynic acid (50% convulsive dose; 50 micrograms/mouse) accelerated the synthesis/turnover of 5-hydroxytryptamine (5-HT) but suppressed the synthesis of gamma-aminobutyric acid and acetylcholine in mouse brain. These effects were completely antagonized by pretreatment with a glutamate/N-methyl-D-aspartate antagonist, aminophosphonovaleric acid. In ethacrynic acid-induced convulsions, these neurotransmitter systems may be differentially modulated, probably through activation of glutaminergic neurons in the brain.

ZK 112119 abecarnil isopropyl 6-benzyloxy-4-methoxymethyl-beta-carboline-3-carboxylate


In rodents, the effect of the beta-carboline derivative isopropyl-6- benzyloxy-4-methoxymethyl-beta-carboline-3-carboxylate (abecarrnil), a new ligand for benzodiazepine receptors possessing anxiolytic and anticonvulsant properties, was evaluated on the function of central gamma-aminobutyric acid (GABA)A receptor complex, both in vitro and in vivo. Added in vitro to rat cortical membrane preparation, abecarnil increased [3H]GABA binding, enhanced muscimol-stimulated 36Cl- uptake and reduced the binding of t-[35S]butylbicyclophosphorothionate ([35S]TBPS). These effects were similar to those induced by diazepam, whereas the partial agonist Ro 16-6028 (tert-butyl-(S)-8-bromo-11,12,13,13a-tetrahydro-9-oxo-9H- imidazo[1,5-a]-pyrrolo-[2,1-c][1,4]benzodiazepine-1-carboxylate) showed very weak efficacy in these biochemical tests. After i.p. injection to rats, abecarnil and diazepam decreased in a time-dependent and dose-related (0.25-20 mg/kg i.p.) manner [35S]TBPS binding measured ex vivo in the cerebral cortex. Moreover, both drugs at the dose of 0.5 mg/kg antagonized completely the convulsant activity and the increase of [35S]TBPS binding induced by isoniazide (350 mg/kg s.c.) as well as the increase of [35S]TBPS binding induced by foot-shock stress. To better correlate the biochemical and the pharmacological effects, we studied the action of abecarnil on [35S]TBPS binding, exploratory motility and on isoniazid-induced biochemical and pharmacological effects in mice. In these animals, abecarnil produced a paralleled dose-dependent (0.05-1 mg/kg i.p.) reduction of both motor behavior and cortical [35S]TBPS binding. Moreover, 0.05 mg/kg of this beta-carboline reduced markedly the increase of [35S]TBPS binding and the convulsions induced by isoniazid (200 mg/kg s.c.).(ABSTRACT TRUNCATED AT 250 WORDS)

Recurrent myocardial infarction in a postpartum patient receiving bromocriptine.

Cardiovascular Stroke Strokes Infarct Myocardial Infarction Infarctions Infarcts

NECROSIS of the MYOCARDIUM caused by an obstruction of the blood supply to the heart (CORONARY CIRCULATION).


Myocardial infarction in puerperium is infrequently reported. Spasm, coronary dissection, or atheromatous etiology has been described. Bromocriptine has been implicated in several previous case reports of myocardial infarction in the puerperium. Our case (including an inadvertent rechallenge) suggests such a relationship. Although generally regarded as "safe," possible serious cardiac effects of bromocriptine should be acknowledged.

Asterixis induced by carbamazepine therapy.

Abnormal Movement Movements Asterixis Ballismus Dyskinesia Dyskinesias Hemiballism Hemiballismus Involuntary

Abnormal involuntary movements which primarily affect the extremities, trunk, or jaw that occur as a manifestation of an underlying disease process. Conditions which feature recurrent or persistent episodes of dyskinesia as a primary manifestation of disease may be referred to as dyskinesia syndromes (see MOVEMENT DISORDERS). Dyskinesias are also a relatively common manifestation of BASAL GANGLIA DISEASES.


Amizepine Carbamazepine Acetate Anhydrous Dihydrate Hydrochloride L-Tartrate (4:1) Phosphate Sulfate (2:1) Carbazepin Epitol Finlepsin Neurotol Tegretol

An anticonvulsant used to control grand mal and psychomotor or focal seizures. Its mode of action is not fully understood, but some of its actions resemble those of PHENYTOIN; although there is little chemical resemblance between the two compounds, their three-dimensional structure is similar.


There are very few reports about asterixis as a side effect of treatment with psychopharmacologic agents. In this report we present four patients treated with a combination of different psychotropic drugs, in whom asterixis was triggered either by adding carbamazepine (CBZ) to a treatment regimen, or by increasing its dosage. Neither dosage nor serum levels of CBZ were in a higher range. We consider asterixis to be an easily overlooked sign of neurotoxicity, which may occur even at low or moderate dosage levels, if certain drugs as lithium or clozapine are used in combination with CBZ.
