Cocaine-induced myocardial infarction: clinical observations and pathogenetic considerations.

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.


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).


Clinical and experimental data published to date suggest several possible mechanisms by which cocaine may result in acute myocardial infarction. In individuals with preexisting, high-grade coronary arterial narrowing, acute myocardial infarction may result from an increase in myocardial oxygen demand associated with cocaine-induced increase in rate-pressure product. In other individuals with no underlying atherosclerotic obstruction, coronary occlusion may be due to spasm, thrombus, or both. With regard to spasm, the clinical findings are largely circumstantial, and the locus of cocaine-induced vasoconstriction remains speculative. Although certain clinical and experimental findings support the hypothesis that spasm involves the epicardial, medium-size vessels, other data suggest intramural vasoconstriction. Diffuse intramural vasoconstriction is not consistent with reports of segmental, discrete infarction. Whereas certain in vivo data suggest that these effects are alpha-mediated, other in vitro data suggest the opposite. The finding of cocaine-induced vasoconstriction in segments of (noninnervated) human umbilical artery suggests that the presence or absence of intact innervation is not sufficient to explain the discrepant data involving the possibility of alpha-mediated effects. Finally, the contribution of a primary, thrombotic effect of cocaine has not been excluded.

Diseases of the BASAL GANGLIA including the PUTAMEN; GLOBUS PALLIDUS; claustrum; AMYGDALA; and CAUDATE NUCLEUS. DYSKINESIAS (most notably involuntary movements and alterations of the rate of movement) represent the primary clinical manifestations of these disorders. Common etiologies include CEREBROVASCULAR DISORDERS; NEURODEGENERATIVE DISEASES; and CRANIOCEREBRAL TRAUMA.


Agents Antidepressive Antidepressant Drugs Antidepressants Thymoanaleptics Thymoleptics

Mood-stimulating drugs used primarily in the treatment of affective disorders and related conditions. Several MONOAMINE OXIDASE INHIBITORS are useful as antidepressants apparently as a long-term consequence of their modulation of catecholamine levels. The tricyclic compounds useful as antidepressive agents (ANTIDEPRESSIVE AGENTS, TRICYCLIC) also appear to act through brain catecholamine systems. A third group (ANTIDEPRESSIVE AGENTS, SECOND-GENERATION) is a diverse group of drugs including some that act specifically on serotonergic systems.


The rabbit syndrome is an extrapyramidal side effect associated with chronic neuroleptic therapy. Its occurrence in a patient being treated with imipramine is described, representing the first reported case of this syndrome in conjunction with antidepressants. Repeated cerebral perfusion SPECT scans revealed decreased basal ganglia perfusion while the movement disorder was present, and a return to normal perfusion when the rabbit syndrome resolved.

A methyl xanthine derivative from tea with diuretic, smooth muscle relaxant, bronchial dilation, cardiac and central nervous system stimulant activities. Theophylline inhibits the 3',5'-CYCLIC NUCLEOTIDE PHOSPHODIESTERASE that degrades CYCLIC AMP thus potentiates the actions of agents that act through ADENYLATE CYCLASE and cyclic AMP.


Airflow Obstruction Chronic Obstructions COAD COPD Obstructive Airway Disease Lung Pulmonary

A disease of chronic diffuse irreversible airflow obstruction. Subcategories of COPD include CHRONIC BRONCHITIS and PULMONARY EMPHYSEMA.


The bronchodilator effects of a single dose of ipratropium bromide aerosol (36 micrograms) and short-acting theophylline tablets (dose titrated to produce serum levels of 10-20 micrograms/mL) were compared in a double-blind, placebo-controlled crossover study in 21 patients with stable, chronic obstructive pulmonary disease. Mean peak forced expiratory volume in 1 second (FEV1) increases over baseline and the proportion of patients attaining at least a 15% increase in the FEV1 (responders) were 31% and 90%, respectively, for ipratropium and 17% and 50%, respectively, for theophylline. The average FEV1 increases during the 6-hour observation period were 18% for ipratropium and 8% for theophylline. The mean duration of action was 3.8 hours with ipratropium and 2.4 hours with theophylline. While side effects were rare, those experienced after theophylline use did involve the cardiovascular and gastrointestinal systems. These results show that ipratropium is a more potent bronchodilator than oral theophylline in patients with chronic airflow obstruction.

Irreversible damage to the medullary interstitium in experimental analgesic nephropathy in F344 rats.

Pathological processes of the KIDNEY or its component tissues.


Renal papillary necrosis (RPN) and a decreased urinary concentrating ability developed during continuous long-term treatment with aspirin and paracetamol in female Fischer 344 rats. Renal structure and concentrating ability were examined after a recovery period of up to 18 weeks, when no analgesics were given, to investigate whether the analgesic-induced changes were reversible. There was no evidence of repair to the damaged medullary interstitial matrix, or proliferation of remaining undamaged type 1 medullary interstitial cells after the recovery period following analgesic treatment. The recovery of urinary concentrating ability was related to the length of analgesic treatment and the extent of the resulting inner medullary structural damage. During the early stages of analgesic treatment, the changes in urinary concentrating ability were reversible, but after prolonged analgesic treatment, maximum urinary concentrating ability failed to recover. This study shows that prolonged analgesic treatment in Fischer 344 rats causes progressive and irreversible damage to the interstitial matrix and type 1 interstitial cells leading to RPN. The associated urinary concentrating defect is reversible only during the early stages of structural damage to the inner medulla.

Kidney Papillary Necrosis Renal Medullary Necrotizing Papillitides Papillitis

A complication of kidney diseases characterized by cell death involving KIDNEY PAPILLA in the KIDNEY MEDULLA. Damages to this area may hinder the kidney to concentrate urine resulting in POLYURIA. Sloughed off necrotic tissue may block KIDNEY PELVIS or URETER. Necrosis of multiple renal papillae can lead to KIDNEY FAILURE.

Less frequent lithium administration and lower urine volume.

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


OBJECTIVE: This study was designed to determine whether patients maintained on a regimen of lithium on a once-per-day schedule have lower urine volumes than do patients receiving multiple doses per day. METHOD: This was a cross-sectional study of 85 patients from a lithium clinic who received different dose schedules. Patients were admitted to the hospital for measurement of lithium level, creatinine clearance, urine volume, and maximum osmolality. RESULTS: Multiple daily doses of lithium were associated with higher urine volumes. The dosing schedule, duration of lithium treatment, and daily dose of lithium did not affect maximum osmolality or creatinine clearance. CONCLUSIONS: Urine volume can be reduced by giving lithium once daily and/or by lowering the total daily dose. Lithium-induced polyuria seems to be related to extrarenal as well as to renal effects.

New abnormal growth of tissue. Malignant neoplasms show a greater degree of anaplasia and have the properties of invasion and metastasis, compared to benign neoplasms.


Thermal enhancement of Adriamycin-mediated antitumor activity and normal tissue toxicities by whole body hyperthermia were compared using a F344 rat model. Antitumor activity was studied using a tumor growth delay assay. Acute normal tissue toxicities (i.e., leukopenia and thrombocytopenia) and late normal tissue toxicities (i.e., myocardial and kidney injury) were evaluated by functional/physiological assays and by morphological techniques. Whole body hyperthermia (120 min at 41.5 degrees C) enhanced both Adriamycin-mediated antitumor activity and toxic side effects. The thermal enhancement ratio calculated for antitumor activity was 1.6. Thermal enhancement ratios estimated for "acute" hematological changes were 1.3, whereas those estimated for "late" damage (based on morphological cardiac and renal lesions) varied between 2.4 and 4.3. Thus, while whole body hyperthermia enhances Adriamycin-mediated antitumor effect, normal tissue toxicity is also increased, and the potential therapeutic gain of the combined modality treatment is eroded.

Involuntary discharge of URINE as a result of physical activities that increase abdominal pressure on the URINARY BLADDER without detrusor contraction or overdistended bladder. The subtypes are classified by the degree of leakage, descent and opening of the bladder neck and URETHRA without bladder contraction, and sphincter deficiency.


A case of genuine stress incontinence due to prazosin, a common antihypertensive drug, is presented. Prazosin exerts its antihypertensive effects through vasodilatation caused by selective blockade of postsynaptic alpha-1 adrenergic receptors. As an alpha-blocker, it also exerts a significant relaxant effect on the bladder neck and urethra. The patient's clinical course is described and correlated with initial urodynamic studies while on prazosin and subsequent studies while taking verapamil. Her incontinence resolved with the change of medication. The restoration of continence was accompanied by a substantial rise in maximum urethral pressure, maximum urethral closure pressure, and functional urethral length. Patients who present with stress incontinence while taking prazosin should change their antihypertensive medication before considering surgery, because their incontinence may resolve spontaneously with a change in drug therapy.

A 78-year-old with healed septal necrosis suffered a recurrent myocardial infarction of the anterior wall following the administration of isosorbide dinitrate 5 mg sublingually. After detailing the course of events, we discuss the role of paradoxical coronary spasm and hypotension-mediated myocardial ischemia occurring downstream to significant coronary arterial stenosis in the pathophysiology of acute coronary insufficiency.

The pathological process occurring in cells that are dying from irreparable injuries. It is caused by the progressive, uncontrolled action of degradative ENZYMES, leading to MITOCHONDRIAL SWELLING, nuclear flocculation, and cell lysis. Distinguish it from APOPTOSIS which is a normal, regulated cellular process.


Ciliary Body Spasm Spasms Generalized Muscle Muscular

An involuntary contraction of a muscle or group of muscles. Spasms may involve SKELETAL MUSCLE or SMOOTH MUSCLE.


Abnormally low BLOOD PRESSURE that can result in inadequate blood flow to the brain and other vital organs. Common symptom is DIZZINESS but greater negative impacts on the body occur when there is prolonged depravation of oxygen and nutrients.


Disease Ischemic Heart Diseases Ischemia Myocardial Ischemias

A disorder of cardiac function caused by insufficient blood flow to the muscle tissue of the heart. The decreased blood flow may be due to narrowing of the coronary arteries (CORONARY ARTERY DISEASE), to obstruction by a thrombus (CORONARY THROMBOSIS), or less commonly, to diffuse narrowing of arterioles and other small vessels within the heart. Severe interruption of the blood supply to the myocardial tissue may result in necrosis of cardiac muscle (MYOCARDIAL INFARCTION).


Narrowing or constriction of a coronary artery.


An episode of MYOCARDIAL ISCHEMIA that generally lasts longer than a transient anginal episode that ultimately may lead to MYOCARDIAL INFARCTION.


Fluoxetine-induced akathisia: clinical and theoretical implications.

Acathisia Drug Induced Drug-Induced Akathisia Tardive Pseudoakathisia

A condition associated with the use of certain medications and characterized by an internal sense of motor restlessness often described as an inability to resist the urge to move.


Five patients receiving fluoxetine for the treatment of obsessive compulsive disorder or major depression developed akathisia. The typical fluoxetine-induced symptoms of restlessness, constant pacing, purposeless movements of the feet and legs, and marked anxiety were indistinguishable from those of neuroleptic-induced akathisia. Three patients who had experienced neuroleptic-induced akathisia in the past reported that the symptoms of fluoxetine-induced akathisia were identical, although somewhat milder. Akathisia appeared to be a common side effect of fluoxetine and generally responded well to treatment with the beta-adrenergic antagonist propranolol, dose reduction, or both. The authors suggest that fluoxetine-induced akathisia may be caused by serotonergically mediated inhibition of dopaminergic neurotransmission and that the pathophysiology of fluoxetine-induced akathisia and tricyclic antidepressant-induced "jitteriness" may be identical.


Anankastic Personalities Personality Disorder Obsessive-Compulsive Disorders Neuroses Neurosis Obsessive Compulsive

Acute Cerebrovascular Accident Accidents Stroke Strokes Apoplexy Brain Vascular CVA (Cerebrovascular Accident) CVAs Cerebral

A group of pathological conditions characterized by sudden, non-convulsive loss of neurological function due to BRAIN ISCHEMIA or INTRACRANIAL HEMORRHAGES. Stroke is classified by the type of tissue NECROSIS, such as the anatomic location, vasculature involved, etiology, age of the affected individual, and hemorrhagic vs. non-hemorrhagic nature. (From Adams et al., Principles of Neurology, 6th ed, pp777-810)


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.


We describe eight patients in whom cocaine use was related to stroke and review 39 cases from the literature. Among these 47 patients the mean (+/- SD) age was 32.5 +/- 12.1 years; 76% (34/45) were men. Stroke followed cocaine use by inhalation, intranasal, intravenous, and intramuscular routes. Intracranial aneurysms or arteriovenous malformations were present in 17 of 32 patients studied angiographically or at autopsy; cerebral vasculitis was present in two patients. Cerebral infarction occurred in 10 patients (22%), intracerebral hemorrhage in 22 (49%), and subarachnoid hemorrhage in 13 (29%). These data indicate that (1) the apparent incidence of stroke related to cocaine use is increasing; (2) cocaine-associated stroke occurs primarily in young adults; (3) stroke may follow any route of cocaine administration; (4) stroke after cocaine use is frequently associated with intracranial aneurysms and arteriovenous malformations; and (5) in cocaine-associated stroke, the frequency of intracranial hemorrhage exceeds that of cerebral infarction.


Aneurysm Anterior Cerebral Artery Communicating Basilar Berry Brain Giant Intracranial Mycotic Middle Posterior Aneurysms

Abnormal outpouching in the wall of intracranial blood vessels. Most common are the saccular (berry) aneurysms located at branch points in CIRCLE OF WILLIS at the base of the brain. Vessel rupture results in SUBARACHNOID HEMORRHAGE or INTRACRANIAL HEMORRHAGES. Giant aneurysms (>2.5 cm in diameter) may compress adjacent structures, including the OCULOMOTOR NERVE. (From Adams et al., Principles of Neurology, 6th ed, p841)


Abnormal formation of blood vessels that shunt arterial blood directly into veins without passing through the CAPILLARIES. They usually are crooked, dilated, and with thick vessel walls. A common type is the congenital arteriovenous fistula. The lack of blood flow and oxygen in the capillaries can lead to tissue damage in the affected areas.


Angiitis Central Nervous System Cerebral Granulomatous Arteritis Postzoster CNS Vasculitis Primary Secondary

Inflammation of blood vessels within the central nervous system. Primary vasculitis is usually caused by autoimmune or idiopathic factors, while secondary vasculitis is caused by existing disease process. Clinical manifestations are highly variable but include HEADACHE; SEIZURES; behavioral alterations; INTRACRANIAL HEMORRHAGES; TRANSIENT ISCHEMIC ATTACK; and BRAIN INFARCTION. (From Adams et al., Principles of Neurology, 6th ed, pp856-61)


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).


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.


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.


Brain Hemorrhage Hemorrhages Intracranial Posterior Fossa

Bleeding within the SKULL, including hemorrhages in the brain and the three membranes of MENINGES. The escape of blood often leads to the formation of HEMATOMA in the cranial epidural, subdural, and subarachnoid spaces.


Daonil Diabeta Euglucon 5 N Glibenclamide Glybenclamide Glyburide HB 419 420 HB-419 HB-420 HB419 HB420 Maninil Micronase Neogluconin

An antidiabetic sulfonylurea derivative with actions similar to those of chlorpropamide.


Drug-induced hepatotoxicity, although common, has been reported only infrequently with sulfonylureas. For glyburide, a second-generation sulfonylurea, only two brief reports of hepatotoxicity exist. Two patients with type II diabetes mellitus developed an acute hepatitis-like syndrome soon after initiation of glyburide therapy. There was no serologic evidence of viral infection, and a liver biopsy sample showed a histologic pattern consistent with drug-induced hepatitis. Both patients recovered quickly after stopping glyburide therapy and have remained well for a follow-up period of 1 year. Glyburide can produce an acute hepatitis-like illness in some persons.


Adult-Onset Diabetes Mellitus Adult Onset Ketosis Resistant Ketosis-Resistant Maturity Maturity-Onset Non Insulin Dependent Non-Insulin-Dependent Noninsulin Noninsulin-Dependent Slow Slow-Onset Stable Type 2 II MODY NIDDM

A subclass of DIABETES MELLITUS that is not INSULIN-responsive or dependent (NIDDM). It is characterized initially by INSULIN RESISTANCE and HYPERINSULINEMIA; and eventually by GLUCOSE INTOLERANCE; HYPERGLYCEMIA; and overt diabetes. Type II diabetes mellitus is no longer considered a disease exclusively found in adults. Patients seldom develop KETOSIS but often exhibit OBESITY.

Abbott Brand of Sodium Nitroprusside Bayer Cyanonitrosylferrate Disodium Salt Faulding Fides Ecopharma Ketostix Naniprus Nipride Nipruton Nitriate Nitroferricyanide Nitropress Nitroprussiat Dihydrate Roche SERB

A powerful vasodilator used in emergencies to lower blood pressure or to improve cardiac function. It is also an indicator for free sulfhydryl groups in proteins.


Abnormally low BLOOD PRESSURE that can result in inadequate blood flow to the brain and other vital organs. Common symptom is DIZZINESS but greater negative impacts on the body occur when there is prolonged depravation of oxygen and nutrients.


The systolic pressure variation (SPV), which is the difference between the maximal and minimal values of the systolic blood pressure (SBP) after one positive-pressure breath, was studied in ventilated dogs subjected to hypotension. Mean arterial pressure was decreased to 50 mm Hg for 30 minutes either by hemorrhage (HEM, n = 7) or by continuous infusion of sodium nitroprusside (SNP, n = 7). During HEM-induced hypotension the cardiac output was significantly lower and systemic vascular resistance higher compared with that in the SNP group. The systemic, central venous, pulmonary capillary wedge pressures, and heart rates, were similar in the two groups. Analysis of the respiratory changes in the arterial pressure waveform enabled differentiation between the two groups. The SPV during hypotension was 15.7 +/- 6.7 mm Hg in the HEM group, compared with 9.1 +/- 2.0 mm Hg in the SNP group (P less than 0.02). The delta down, which is the measure of decrease of SBP after a mechanical breath, was 20.3 +/- 8.4 and 10.1 +/- 3.8 mm Hg in the HEM and SNP groups, respectively, during hypotension (P less than 0.02). It is concluded that increases in the SPV and the delta down are characteristic of a hypotensive state due to a predominant decrease in preload. They are thus more important during absolute hypovolemia than during deliberate hypotension.


Hypovolemia Hypovolemias Hypovolemic Hypovolemics

An abnormally low volume of blood circulating through the body. It may result in hypovolemic shock (see SHOCK).


Drug-induced arterial spasm relieved by lidocaine. Case report.

A local anesthetic and cardiac depressant used as an antiarrhythmia agent. Its actions are more intense and its effects more prolonged than those of PROCAINE but its duration of action is shorter than that of BUPIVACAINE or PRILOCAINE.


Following major intracranial surgery in a 35-year-old man, sodium pentothal was intravenously infused to minimize cerebral ischaemia. Intense vasospasm with threatened gangrene arose in the arm used for the infusion.

Abnormal outpouching in the wall of intracranial blood vessels. Most common are the saccular (berry) aneurysms located at branch points in CIRCLE OF WILLIS at the base of the brain. Vessel rupture results in SUBARACHNOID HEMORRHAGE or INTRACRANIAL HEMORRHAGES. Giant aneurysms (>2.5 cm in diameter) may compress adjacent structures, including the OCULOMOTOR NERVE. (From Adams et al., Principles of Neurology, 6th ed, p841)


Cerebral blood flow and cerebral metabolic rate for oxygen were measured during isoflurane-induced hypotension in 10 patients subjected to craniotomy for clipping of a cerebral aneurysm. Flow and metabolism were measured 5-13 days after the subarachnoid haemorrhage by a modification of the classical Kety-Schmidt technique using xenon-133 i.v. Anaesthesia was maintained with an inspired isoflurane concentration of 0.75% (plus 67% nitrous oxide in oxygen), during which CBF and CMRO2 were 34.3 +/- 2.1 ml/100 g min-1 and 2.32 +/- 0.16 ml/100 g min-1 at PaCO2 4.1 +/- 0.1 kPa (mean +/- SEM). Controlled hypotension to an average MAP of 50-55 mm Hg was induced by increasing the dose of isoflurane, and maintained at an inspired concentration of 2.2 +/- 0.2%. This resulted in a significant decrease in CMRO2 (to 1.73 +/- 0.16 ml/100 g min-1), while CBF was unchanged. After the clipping of the aneurysm the isoflurane concentration was reduced to 0.75%. There was a significant increase in CBF, although CMRO2 was unchanged, compared with pre-hypotensive values. These changes might offer protection to brain tissue during periods of induced hypotension.

A drug that is used in the management of inflammatory bowel diseases. Its activity is generally considered to lie in its metabolic breakdown product, 5-aminosalicylic acid (see MESALAMINE) released in the colon. (From Martindale, The Extra Pharmacopoeia, 30th ed, p907)


Three infants, born of two mothers with inflammatory bowel disease who received treatment with sulphasalazine throughout pregnancy, were found to have major congenital anomalies. In the singleton pregnancy, the mother had ulcerative colitis, and the infant, a male, had coarctation of the aorta and a ventricular septal defect. In the twin pregnancy, the mother had Crohn's disease. The first twin, a female, had a left Potter-type IIa polycystic kidney and a rudimentary left uterine cornu. The second twin, a male, had some features of Potter's facies, hypoplastic lungs, absent kidneys and ureters, and talipes equinovarus. Despite reports to the contrary, it is suggested that sulphasalazine may be teratogenic.

An octapeptide analog of angiotensin II (bovine) with amino acids 1 and 8 replaced with sarcosine and alanine, respectively. It is a highly specific competitive inhibitor of angiotensin II that is used in the diagnosis of HYPERTENSION.


The role of the renin--angiotensin system in the maintenance of blood pressure during halothane anesthesia and sodium nitroprusside (SNP)-induced hypotension was evaluated. Control rats received halothane anesthesia (1 MAC) for one hour, followed by SNP infusion, 40 microgram/kg/min, for 30 min, followed by a 30-min recovery period. A second group of rats was treated identically and, in addition, received an infusion of saralasin (a competitive inhibitor of angiotensin II) throughout the experimental period. In each group, SNP infusion resulted in an initial decrease in blood pressure from 86 torr and 83 torr, respectively, to 48 torr. During the SNP infusion the control animals demonstrated a progressive increase in blood pressure to 61 torr, whereas the saralasin-treated animals showed no change. Following discontinuation of SNP, blood pressure in the control animals rebounded to 94 torr, as compared with 78 torr in the saralasin-treated rats. This study indicates that with stable halothane anesthesia, the partial recovery of blood pressure during SNP infusion and the post-SNP rebound of blood pressure can be completely blocked by saralasin. This demonstrates the participation of the renin--angiotensin system in antagonizing the combined hypotensive effects of halothane and SNP.

6-benzyl-2-thiouracil Basdène Hexaspray benzylthiouracil


OBJECTIVE: This study was conducted to assess the occurrence of hepatic adverse effects encountered with antithyroid drugs. METHODS: Retrospective review of medical records of 236 patients with hyperthyroidism admitted in our department (in- or out-patients) from 1986 to 1992. RESULTS: Four patients (1.7%) were identified with toxic hepatitis which could reasonably be attributed to the use of antithyroid agent. Two patients had a cholestatic hepatitis induced by carbimazole (N  omercazole). Two others had a mixed (cholestatic and cytolytic) hepatitis following carbimazole. One of the latter two patients further experienced a cytolytic hepatitis which appeared after Benzylthiouracil (Basd  ne) had replaced carbimazole. Biological features of hepatitis disappeared in all cases after cessation of the incriminated drug, while biliary, viral and immunological searches were negative. Only 2 patients of our retrospective study experienced a mild or severe neutropenia. CONCLUSION: Toxic hepatitis is a potential adverse effect of antithyroid drugs which warrants, as for haematological disturbances, a pre-therapeutic determination and a careful follow-up of relevant biological markers. Moreover, hepatotoxicity may not be restricted to one class of antithyroid agents.

A dideoxynucleoside compound in which the 3'-hydroxy group on the sugar moiety has been replaced by an azido group. This modification prevents the formation of phosphodiester linkages which are needed for the completion of nucleic acid chains. The compound is a potent inhibitor of HIV replication, acting as a chain-terminator of viral DNA during reverse transcription. It improves immunologic function, partially reverses the HIV-induced neurological dysfunction, and improves certain other clinical abnormalities associated with AIDS. Its principal toxic effect is dose-dependent suppression of bone marrow, resulting in anemia and leukopenia.


A prospective, randomized study was conducted to evaluate the role of vitamin B12 and folinic acid supplementation in preventing zidovudine (ZDV)-induced bone marrow suppression. Seventy-five human immunodeficiency virus (HIV)-infected patients with CD4+ cell counts < 500/mm3 were randomized to receive either ZDV (500 mg daily) alone (group I, n = 38) or in combination with folinic acid (15 mg daily) and intramascular vitamin B12 (1000 micrograms monthly) (group II, n = 37). Finally, 15 patients were excluded from the study (noncompliance 14, death 1); thus, 60 patients (31 in group I and 29 in group II) were eligible for analysis. No significant differences between groups were found at enrollment. During the study, vitamin B12 and folate levels were significantly higher in group II patients; however, no differences in hemoglobin, hematocrit, mean corpuscular volume, and white-cell, neutrophil and platelet counts were observed between groups at 3, 6, 9 and 12 months. Severe hematologic toxicity (neutrophil count < 1000/mm3 and/or hemoglobin < 8 g/dl) occurred in 4 patients assigned to group I and 7 assigned to group II. There was no correlation between vitamin B12 or folate levels and development of myelosuppression. Vitamin B12 and folinic acid supplementation of ZDV therapy does not seem useful in preventing or reducing ZDV-induced myelotoxicity in the overall treated population, although a beneficial effect in certain subgroups of patients cannot be excluded.

A 61-year-old man was treated with combination chemotherapy incorporating cisplatinum, etoposide, high-dose 5-fluorouracil (2,250 mg/m2/24 hours) and folinic acid for an inoperable gastric adenocarcinoma. He developed acute neurologic symptoms of mental confusion, disorientation and irritability, and then lapsed into a deep coma, lasting for approximately 40 hours during the first dose (day 2) of 5-fluorouracil and folinic acid infusion. This complication reappeared on day 25 during the second dose of 5-fluorouracil and folinic acid, which were then the only drugs given. Because folinic acid was unlikely to be associated with this condition, neurotoxicity due to high-dose 5-fluorouracil was highly suspected. The pathogenesis of 5-fluorouracil neurotoxicity may be due to a Krebs cycle blockade by fluoroacetate and fluorocitrate, thiamine deficiency, or dihydrouracil dehydrogenase deficiency. High-dose 5-fluorouracil/folinic acid infusion therapy has recently become a popular regimen for various cancers. It is necessary that both oncologists and neurologists be fully aware of this unusual complication.

Desitin brand of oxcarbazepine GP 47680 Novartis Timox Trileptal


Carbamazepine was switched to its 10-keto analogue oxcarbazepine among six difficult-to-treat schizophrenic or organic psychotic patients using concomitantly haloperidol, chlorpromazine or clozapine. This change resulted within 2-4 weeks in the 50-200% increase in the plasma levels of these neuroleptics and the appearance of extrapyramidal symptoms. None of the patients showed any clinical deteriotation during the following 3-6 months. The results of this case report support the idea that in contrast with carbamazepine oxcarbazepine does not induce the hepatic microsomal enzyme systems regulating the inactivation of antipsychotic drugs.

OBJECTIVE: To report a case of erythema multiforme and hypersensitivity myocarditis caused by ampicillin. CASE SUMMARY: A 13-year-old boy was treated with ampicillin and gentamicin because of suspected septicemia. Medications were discontinued when erythema multiforme and congestive heart failure caused by myocarditis occurred. The patient was treated with methylprednisolone and gradually improved. Macrophage-migration inhibition (MIF) test with ampicillin was positive. DISCUSSION: After most infections causing erythema multiforme and myocarditis were ruled out, a drug-induced allergic reaction was suspected. Positive MIF test for ampicillin showed sensitization of the patient's lymphocytes to ampicillin. CONCLUSIONS: Hypersensitivity myocarditis is a rare and dangerous manifestation of allergy to penicillins.

A broad-spectrum semisynthetic antibiotic similar to AMPICILLIN except that its resistance to gastric acid permits higher serum levels with oral administration.


A large group of patients with suspected allergic reactions to beta-lactam antibiotics was evaluated. A detailed clinical history, together with skin tests, RAST (radioallergosorbent test), and controlled challenge tests, was used to establish whether patients allergic to beta-lactam antibiotics had selective immediate allergic responses to amoxicillin (AX) or were cross-reacting with other penicillin derivatives. Skin tests were performed with benzylpenicilloyl-poly-L-lysine (BPO-PLL), benzylpenicilloate, benzylpenicillin (PG), ampicillin (AMP), and AX. RAST for BPO-PLL and AX-PLL was done. When both skin test and RAST for BPO were negative, single-blind, placebo-controlled challenge tests were done to ensure tolerance of PG or sensitivity to AX. A total of 177 patients were diagnosed as allergic to beta-lactam antibiotics. We selected the 54 (30.5%) cases of immediate AX allergy with good tolerance of PG. Anaphylaxis was seen in 37 patients (69%), the other 17 (31%) having urticaria and/or angioedema. All the patients were skin test negative to BPO; 49 of 51 (96%) were also negative to MDM, and 44 of 46 (96%) to PG. Skin tests with AX were positive in 34 (63%) patients. RAST was positive for AX in 22 patients (41%) and to BPO in just 5 (9%). None of the sera with negative RAST for AX were positive to BPO. Challenge tests with AX were performed in 23 subjects (43%) to establish the diagnosis of immediate allergic reaction to AX, and in 15 cases (28%) both skin test and RAST for AX were negative. PG was well tolerated by all 54 patients. We describe the largest group of AX-allergic patients who have tolerated PG reported so far. Diagnosis of these patients can be achieved only if specific AX-related reagents are employed. Further studies are necessary to determine the exact extent of this problem and to improve the efficacy of diagnostic methods.

33 A 74 Atracurium Besilate Besylate Dibesylate BW 33A BW-33A BW33A Glaxo Wellcome Brand of Pisa Relatrac Tracrium

A non-depolarizing neuromuscular blocking agent with short duration of action. Its lack of significant cardiovascular effects and its lack of dependence on good kidney function for elimination provide clinical advantage over alternate non-depolarizing neuromuscular blocking agents.


Neuromuscular blocking agents (NMBAs) are often used for patients requiring prolonged mechanical ventilation. Reports of persistent paralysis after the discontinuance of these drugs have most often involved aminosteroid-based NMBAs such as vecuronium bromide, especially when used in conjunction with corticosteroids. Atracurium besylate, a short-acting benzylisoquinolinium NMBA that is eliminated independently of renal or hepatic function, has also been associated with persistent paralysis, but only when used with corticosteroids. We report a case of atracurium-related paralysis persisting for approximately 50 hours in a patient who was not treated with corticosteroids.

Chronic Kidney Failure Renal Disease End-Stage ESRD End Stage

The end-stage of CHRONIC RENAL INSUFFICIENCY. It is characterized by the severe irreversible kidney damage (as measured by the level of PROTEINURIA) and the reduction in GLOMERULAR FILTRATION RATE to less than 15 ml per min (Kidney Foundation: Kidney Disease Outcome Quality Initiative, 2002). These patients generally require HEMODIALYSIS or KIDNEY TRANSPLANTATION.


A phenylacetamide that was formerly used in ANALGESICS but nephropathy and METHEMOGLOBINEMIA led to its withdrawal from the market. (From Smith and Reynard, Textbook of Pharmacology,1991, p431)


Six epidemiologic studies in the United States and Europe indicate that habitual use of phenacetin is associated with the development of chronic renal failure and end-stage renal disease (ESRD), with a relative risk in the range of 4 to 19. As a result of these and other studies, phenacetin has now been withdrawn from the market in most countries. However, three case control studies, one each in North Carolina, northern Maryland, and West Berlin, Germany, showed that habitual use of acetaminophen is also associated with chronic renal failure and ESRD, with a relative risk in the range of 2 to 4. These studies suggest that both phenacetin and acetaminophen may contribute to the burden of ESRD, with the risk of the latter being somewhat less than that of the former. This apparent difference in risk may not be due to differences in nephrotoxic potential of the drugs themselves. A lower relative risk would be expected for acetaminophen if the risk of both drugs in combination with other analgesics was higher than the risk of either agent alone. Thus, acetaminophen has been used both as a single agent and in combination with other analgesics, whereas phenacetin was available only in combinations. The possibility that habitual use of acetaminophen alone increases the risk of ESRD has not been clearly demonstrated, but cannot be dismissed.

Diabetic Glomerulosclerosis Kidney Disease Diseases Nephropathies Nephropathy Nodular Intracapillary Kimmelstiel Wilson Syndrome Kimmelstiel-Wilson

KIDNEY injuries associated with diabetes mellitus and affecting KIDNEY GLOMERULUS; ARTERIOLES; KIDNEY TUBULES; and the interstitium. Clinical signs include persistent PROTEINURIA, from microalbuminuria progressing to ALBUMINURIA of greater than 300 mg/24 h, leading to reduced GLOMERULAR FILTRATION RATE and END-STAGE RENAL DISEASE.


Heparan sulphate-associated anionic sites in the glomerular basement membrane were studied in rats 8 months after induction of diabetes by streptozotocin and in age- adn sex-matched control rats, employing the cationic dye cuprolinic blue. Morphometric analysis at the ultrastructural level was performed using a computerized image processor. The heparan sulphate specificity of the cuprolinic blue staining was demonstrated by glycosaminoglycan-degrading enzymes, showing that pretreatment of the sections with heparitinase abolished all staining, whereas chondroitinase ABC had no effect. The majority of anionic sites (74% in diabetic and 81% in control rats) were found within the lamina rara externa of the glomerular basement membrane. A minority of anionic sites were scattered throughout the lamina densa and lamina rara interna, and were significantly smaller than those in the lamina rara externa of the glomerular basement membrane (p<0.001 and p<0.01 for diabetic and control rats, respectively). Diabetic rats progressively developed albuminuria reaching 40.3 (32.2-62.0) mg/24 h after 8 months in contrast to the control animals (0.8 (0.2-0.9) mg/24 h, p<0.002). At the same time, the number of heparan sulphate anionic sites and the total anionic site surface (number of anionic sites x mean anionic site surface) in the lamina rara externa of the glomerular basement membrane was reduced by 19% (p<0.021) and by 26% (p<0.02), respectively. Number and total anionic site surface in the remaining part of the glomerular basement membrane (lamina densa and lamina rara interna) were not significantly changed. We conclude that in streptozotocin-diabetic rats with an increased urinary albumin excretion, a reduced heparan sulphate charge barrier/density is found at the lamina rara externa of the glomerular basement membrane.

Effect of some anticancer drugs and combined chemotherapy on renal toxicity.


The nephrotoxic action of anticancer drugs such as nitrogranulogen (NG), methotrexate (MTX), 5-fluorouracil (5-FU) and cyclophosphamide (CY) administered alone or in combination [MTX + 5-FU + CY (CMF)] was evaluated in experiments on Wistar rats. After drug administration, creatinine concentrations in the plasma and in the urine of the rats were determined, as well as creatinine clearance. Histopathologic evaluation of the kidneys was also performed. After MTX administration a significant increase (p = 0.0228) in the plasma creatinine concentration and a significant (p = 0.0001) decrease in creatinine clearance was noted compared to controls. After the administration of NG, 5-FU and CY neither a statistically significant increase in creatinine concentration nor an increase in creatinine clearance was observed compared to the group receiving no cytostatics. Following polytherapy according to the CMF regimen, a statistically significant decrease (p = 0.0343) in creatinine clearance was found, but creatinine concentration did not increase significantly compared to controls. CY caused hemorrhagic cystitis in 40% of rats, but it did not cause this complication when combined with 5-FU and MTX. Histologic changes were found in rat kidneys after administration of MTX, CY and NG, while no such change was observed after 5-FU and joint administration of MTX + 5-FU + CY compared to controls. Our studies indicate that nephrotoxicity of MTX + 5-FU + CY administered jointly is lower than in monotherapy.
