OBJECTIVE: To report a case of persistent hiccups associated by azithromycin therapy. CASE SUMMARY: A 76-year-old man presented with persistent hiccups after beginning azithromycin for the treatment of pharyngitis. Hiccups were persistent and exhausting. Discontinuation of azithromycin and therapy with baclofen finally resolved hiccups. No organic cause of hiccups was identified despite extensive investigation. DISCUSSION: Pharmacotherapeutic agents have been uncommonly associated with hiccups. Corticosteroids (dexamethasone and methylprednisolone), benzodiazepines (midazolam) and general anaesthesia have been the specific agents mentioned most frequently in the literature as being associated with the development of hiccups. Few cases of drug-induced hiccups have been reported related to macrolide antimicrobials. Using the Naranjo adverse effect reaction probability scale this event could be classified as possible (score 5 points), mostly because of the close temporal sequence, previous reports on this reaction with other macrolides and the absence of any alternative explanation for hiccups. Our hypothesis is that a vagal mechanism mediated by azithromycin could be the pathogenesis of hiccups in our patient. CONCLUSIONS: Diagnosis of drug-induced hiccups is difficult and often achieved only by a process of elimination. However, macrolide antimicrobials have been reported to be associated with hiccups and vagal mechanism could explain the development of this side-effect.

Acute Onset Aura Migraine Basilar Artery Migraines Type Basilar-Type Classic Classical Complicated Familial Hemiplegic Hemiplegic-Ophthalmoplegic without Headache with Auras Prolonged Typical

A subtype of migraine disorder, characterized by recurrent attacks of reversible neurological symptoms (aura) that precede or accompany the headache. Aura may include a combination of sensory disturbances, such as blurred VISION; HALLUCINATIONS; VERTIGO; NUMBNESS; and difficulty in concentrating and speaking. Aura is usually followed by features of the COMMON MIGRAINE, such as PHOTOPHOBIA; PHONOPHOBIA; and NAUSEA. (International Classification of Headache Disorders, 2nd ed. Cephalalgia 2004: suppl 1)


Migraine with aura and migraine without aura have the same pain phase, thus indicating that migraine with aura and migraine without aura share a common pathway of nociception. In recent years, increasing evidence has suggested that the messenger molecule nitric oxide (NO) is involved in pain mechanisms of migraine without aura. In order to clarify whether the same is true for migraine with aura, in the present study we examined the headache response to intravenous infusion of glyceryl trinitrate (GTN) (0.5 microg/kg/min for 20 min) in 12 sufferers of migraine with aura. The specific aim was to elucidate whether an aura and/or an attack of migraine without aura could be induced. Fourteen healthy subjects served as controls. Aura symptoms were not elicited in any subject. Headache was more severe in migraineurs than in the controls during and immediately after GTN infusion (p=0.037) as well as during the following 11 h (p = 0.008). In the controls, the GTN-induced headache gradually disappeared, whereas in migraineurs peak headache intensity occurred at a mean time of 240 min post-infusion. At this time the induced headache in 6 of 12 migraineurs fulfilled the diagnostic criteria for migraine without aura of the International Headache Society. The results therefore suggest that NO is involved in the pain mechanisms of migraine with aura. Since cortical spreading depression has been shown to liberate NO in animals, this finding may help our understanding of the coupling between cortical spreading depression and headache in migraine with aura.

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.


Amfetamine Amphetamine Sulfate (2:1) Centramina Desoxynorephedrin Fenamine Levoamphetamine Miquel Brand of Mydrial Phenamine Phenopromin Thyramine l l-Amphetamine levo levo-Amphetamine

A powerful central nervous system stimulant and sympathomimetic. Amphetamine has multiple mechanisms of action including blocking uptake of adrenergics and dopamine, stimulation of release of monamines, and inhibiting monoamine oxidase. Amphetamine is also a drug of abuse and a psychotomimetic. The l- and the d,l-forms are included here. The l-form has less central nervous system activity but stronger cardiovascular effects. The d-form is DEXTROAMPHETAMINE.


The association of cocaine and amphetamine use with hemorrhagic and ischemic stroke is based almost solely on data from case series. The limited number of epidemiologic studies of stroke and use of cocaine and/or amphetamine have been done in settings that serve mostly the poor and/or minorities. This case-control study was conducted in the defined population comprising members of Kaiser Permanente of Northern and Southern California. We attempted to identify all incident strokes in women ages 15-44 years during a 3-year period using hospital admission and discharge records, emergency department logs, and payment requests for out-of-plan hospitalizations. We selected controls, matched on age and facility of usual care, at random from healthy members of the health plan. We obtained information in face-to-face interviews. There were 347 confirmed stroke cases and 1,021 controls. The univariate matched odds ratio for stroke in women who admitted to using cocaine and/or amphetamine was 8.5 (95% confidence interval = 3.6-20.0). After further adjustment for potential confounders, the odds ratio in women who reported using cocaine and/or amphetamine was 7.0 (95% confidence interval = 2.8-17.9). The use of cocaine and/or amphetamine is a strong risk factor for stroke in this socioeconomically heterogeneous, insured urban population.

Prevention of breast cancer with tamoxifen: preliminary findings from the Italian randomised trial among hysterectomised women. Italian Tamoxifen Prevention Study.

Breast Cancer Carcinoma Neoplasm Neoplasms Tumor Tumors of the Human Mammary Carcinomas Malignant


Citrate Tamoxifen ICI 46,474 46474 47699 ICI-46,474 ICI-46474 ICI-47699 ICI46,474 ICI46474 ICI47699 Nolvadex Novaldex Savient brand of Soltamox Tomaxithen Zitazonium

One of the SELECTIVE ESTROGEN RECEPTOR MODULATORS with tissue-specific activities. Tamoxifen acts as an anti-estrogen (inhibiting agent) in the mammary tissue, but as an estrogen (stimulating agent) in cholesterol metabolism, bone density, and cell proliferation in the ENDOMETRIUM.


BACKGROUND: Tamoxifen is a candidate chemopreventive agent in breast cancer, although the drug may be associated with the development of endometrial cancer. Therefore we did a trial in hysterectomised women of tamoxifen as a chemopreventive. METHODS: In October, 1992, we started a double-blind placebo-controlled, randomised trial of tamoxifen in women (mainly in Italy) who did not have breast cancer and who had had a hysterectomy. Women were randomised to receive tamoxifen 20 mg per day or placebo, both orally for 5 years. The original plan was to follow the intervention phase by 5 years' follow-up. In June, 1997, the trialists and the data-monitoring committee decided to end recruitment primarily because of the number of women dropping out of the study. Recruitment ended on July 11, 1997, and the study will continue as planned. The primary endpoints are the occurrence of and deaths from breast cancer. This preliminary interim analysis is based on intention-to-treat. FINDINGS: 5408 women were randomised; participating women have a median follow-up of 46 months for major endpoints. 41 cases of breast cancer occurred so far; there have been no deaths from breast cancer. There is no difference in breast-cancer frequency between the placebo (22 cases) and tamoxifen (19) arms. There is a statistically significant reduction of breast cancer among women receiving tamoxifen who also used hormone-replacement therapy during the trial: among 390 women on such therapy and allocated to placebo, we found eight cases of breast cancer compared with one case among 362 women allocated to tamoxifen. Compared with the placebo group, there was a significantly increased risk of vascular events and hypertriglyceridaemia among women on tamoxifen. INTERPRETATION: Although this preliminary analysis has low power, in this cohort of women at low-to-normal risk of breast cancer, the postulated protective effects of tamoxifen are not yet apparent. Women using hormone-replacement therapy appear to have benefited from use of tamoxifen. There were no deaths from breast cancer recorded in women in the study. It is essential to continue follow-up to quantify the long-term risks and benefits of tamoxifen therapy.

Disorder Paranoid Disorders Paranoia Paranoias Psychoses

Chronic mental disorders in which there has been an insidious development of a permanent and unshakeable delusional system (persecutory delusions or delusions of jealousy), accompanied by preservation of clear and orderly thinking. Emotional responses and behavior are consistent with the delusional state.


Cocaine-induced paranoia (CIP) remains an important drug-induced model of idiopathic paranoia for which no psychophysiologic marker has yet emerged. Measures of pupillary oscillation were able to significantly distinguish a group of abstinent crack cocaine abusers endorsing past CIP (n = 32) from another group of crack addicts who denied past CIP (n = 29).


The purified, alkaloidal, extra-potent form of cocaine. It is smoked (free-based), injected intravenously, and orally ingested. Use of crack results in alterations in function of the cardiovascular system, the autonomic nervous system, the central nervous system, and the gastrointestinal system. The slang term "crack" was derived from the crackling sound made upon igniting of this form of cocaine for smoking.

A histamine congener, it competitively inhibits HISTAMINE binding to HISTAMINE H2 RECEPTORS. Cimetidine has a range of pharmacological actions. It inhibits GASTRIC ACID secretion, as well as PEPSIN and GASTRIN output.


The H2-histamine receptor antagonists ranitidine and cimetidine were compared for their abilities to control gastric acid hypersecretion on a short- and long-term basis in 22 patients with gastric acid hypersecretory states. Nineteen patients had Zollinger-Ellison syndrome, one patient had systemic mastocytosis, and two patients had idiopathic hypersecretion. The rates of onset of the action of cimetidine and ranitidine were the same. The actions of both drugs were increased by anticholinergic agents, and there was a close correlation between the daily maintenance dose of each drug needed to control acid secretion. However, ranitidine was threefold more potent than cimetidine both in acute inhibition studies and in the median maintenance dose needed (1.2 g per day for ranitidine and 3.6 g per day for cimetidine). Sixty percent of the males developed breast changes or impotence while taking cimetidine and in all cases these changes disappeared when cimetidine was replaced by ranitidine. Treatment with high doses of cimetidine (one to 60 months; median, 11 months) or ranitidine (two to 31 months; median, 14 months) was not associated with hepatic or hematologic toxicity or alterations of serum gastrin concentrations, but ranitidine therapy was associated with a significantly lower serum creatinine level than seen with cimetidine therapy. The results show that both drugs can adequately inhibit acid secretion in patients with gastric hypersecretory states. Both are safe at high doses, but ranitidine is threefold more potent and does not cause the antiandrogen side effects frequently seen with high doses of cimetidine.

Adult Reye Syndrome Reye's Fatty Liver with Encephalopathy Johnson Like Reye's-Like Reye-Johnson Reye-Like

A form of encephalopathy with fatty infiltration of the LIVER, characterized by brain EDEMA and VOMITING that may rapidly progress to SEIZURES; COMA; and DEATH. It is caused by a generalized loss of mitochondrial function leading to disturbances in fatty acid and CARNITINE metabolism.


Twenty-six cases of Reye syndrome from The Children's Hospital, Camperdown, Australia, occurring between 1973 and 1982 were reviewed. Of these, 20 cases met the US Public Health Service Centers for Disease Control criteria for the diagnosis of Reye syndrome. Aspirin or salicylate ingestion had occurred in only one of the 20 cases (5%), and paracetamol (acetaminophen) had been administered in only six of the cases (30%). Pathologic confirmation of the diagnosis of Reye syndrome was accomplished in 90% of the cases. The incidence of Reye syndrome in New South Wales, Australia, is estimated from this study to be approximately nine cases per 1 million children compared with recent US data of ten to 20 cases per 1 million children and three to seven cases per 1 million children in Great Britain. The mortality for these Reye syndrome cases in Australia was 45% as compared with a 32% case-fatality rate in the United States. In Australia, the pediatric usage of aspirin has been extremely low for the past 25 years (less than 1% of total dosage units sold), with paracetamol (acetaminophen) dominating the pediatric analgesic and antipyretic market. Reye syndrome may be disappearing from Australia despite a total lack of association with salicylates or aspirin ingestion, since there were no cases found at The Children's Hospital in 1983, 1984, or 1985.

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

Coretal Hydrochloride Oxprenolol Koretal Slow Trasicor Tevacor

A beta-adrenergic antagonist used in the treatment of hypertension, angina pectoris, arrhythmias, and anxiety.


The time course and concentration-effect relationship of terbutaline-induced hypokalemia was studied, using computer-aided pharmacokinetic-dynamic modeling. Subsequently we investigated the efficacy of oxprenolol in antagonizing such hypokalemia, together with the pharmacokinetic interaction between both drugs. Six healthy subjects were given a 0.5 mg subcutaneous dose of terbutaline on two occasions: 1 hour after oral administration of a placebo and 1 hour after 80 mg oxprenolol orally. In the 7-hour period after terbutaline administration, plasma samples were taken for determination of plasma potassium levels and drug concentrations. The sigmoid Emax model offered a good description of the relation between terbutaline concentrations and potassium effects. Oxprenolol caused decreases of 65% and 56% of terbutaline volume of distribution and clearance, respectively, and an increase of 130% of its AUC. In spite of higher terbutaline concentrations after oxprenolol pretreatment, the hypokalemia was almost completely antagonized by the beta 2-blocking action.

An alpha-2 adrenergic agonist that has both central and peripheral nervous system effects. Its primary clinical use is as an antihypertensive agent.


Previous experiments in this laboratory have shown that microinjection of methyldopa onto the ventrolateral cells of the B3 serotonin neurons in the medulla elicits a hypotensive response mediated by a projection descending into the spinal cord. The present experiments were designed to investigate the role of the midline cells of the B3 serotonin neurons in the medulla, coinciding with the raphe magnus. In spontaneously hypertensive, stroke-prone rats, microinjection of methyldopa into the area of the midline B3 serotonin cell group in the ventral medulla caused a potent hypotension of 30-40 mm Hg, which was maximal 2-3 h after administration and was abolished by the serotonin neurotoxin 5,7-dihydroxytryptamine (5,7-DHT) injected intracerebroventricularly. However, intraspinal injection of 5,7-DHT to produce a more selective lesion of only descending serotonin projections in the spinal cord did not affect this hypotension. Further, 5,7-DHT lesion of serotonin nerves travelling in the median forebrain bundle, one of the main ascending pathways from the B3 serotonin cells, did not affect the fall in blood pressure associated with a midline B3 serotonin methyldopa injection. It is concluded therefore that, unlike the ventrolateral B3 cells which mediate a methyldopa-induced hypotension via descending projections, the midline serotonin B3 cells in the medulla contribute to the hypotensive action of methyldopa, either by way of an ascending projection which does not pass through the median forebrain bundle, or through a projection restricted to the caudal brainstem.

Arousal Disorders Sexual Aversion Disorder Psychosexual Orgasmic Dysfunction Psychological Dysfunctions Frigidity Hypoactive Desire

Disturbances in sexual desire and the psychophysiologic changes that characterize the sexual response cycle and cause marked distress and interpersonal difficulty. (APA, DSM-IV, 1994)


BACKGROUND: Preclinical and clinical studies suggest that yohimbine facilitates sexual behavior and may be helpful in the treatment of male impotence. A single case report suggests that yohimbine may be used to treat the sexual side effects of clomipramine. This study evaluated yohimbine as a treatment for the sexual side effects caused by serotonin reuptake blockers. METHOD: Six patients with either obsessive compulsive disorder, trichotillomania, anxiety, or affective disorders who suffered sexual side effects after treatment with serotonin reuptake blockers were given yohimbine on a p.r.n. basis in an open clinical trial. Various doses of yohimbine were used to determine the ideal dose for each patient. RESULTS: Five of the six patients experienced improved sexual functioning after taking yohimbine. One patient who failed to comply with yohimbine treatment had no therapeutic effects. Side effects of yohimbine included excessive sweating, increased anxiety, and a wound-up feeling in some patients. CONCLUSION: The results of this study indicate that yohimbine may be an effective treatment for the sexual side effects caused by serotonin reuptake blockers. Future controlled studies are needed to further investigate the effectiveness and safety of yohimbine for this indication.

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.


OBJECTIVE: To assess lymphocyte reactivity to dilevalol and to serum containing putative ex vivo dilevalol antigens or metabolites in a case of dilevalol-induced liver injury. PATIENT: A 58-year-old woman with a clinical diagnosis of dilevalol-induced liver injury. METHODS: Peripheral blood mononuclear cells collected from the patient were cultured in the presence of a solution of dilevalol and also with sera collected from a volunteer before and after dilevalol intake. A similar protocol was performed with lymphocytes from a healthy subject. RESULTS: No lymphocyte proliferation was observed either in the patient or in the healthy volunteer in the presence of dilevalol solutions. A significant proliferative response to serum collected after dilevalol intake was observed in the case of the patient compared with the proliferative response to the serum collected before the drug intake. No reactivity was found when lymphocytes from the healthy subject were tested under similar conditions. CONCLUSIONS: The methodology used allowed the detection of lymphocyte sensitization to sera containing ex vivo-prepared dilevalol antigens, suggesting the involvement of an immunologic mechanism in dilevalol-induced liver injury.


Reversible myocardial hypertrophy induced by tacrolimus in a pediatric heart transplant recipient: case report.

Anhydrous Tacrolimus Cilag Brand of FK 506 FK-506 FK506 FR 900506 FR-900506 FR900506 Fujisawa Janssen Prograf Prograft

A macrolide isolated from the culture broth of a strain of Streptomyces tsukubaensis that has strong immunosuppressive activity in vivo and prevents the activation of T-lymphocytes in response to antigenic or mitogenic stimulation in vitro.


Tacrolimus is a potent immunosuppressant that is frequently used in organ transplantation. However, adverse effects include cardiac toxicity. Herein we describe transient myocardial hypertrophy induced by tacrolimus after heart transplantation. The hypertrophy caused no clinical symptoms but was noted because of elevation of plasma brain natriuretic peptide concentration and confirmed at echocardiography. Initially, allograft rejection was feared; however, myocardial biopsy samples revealed only interstitial edema and mild myocardial hypertrophy; neither cellular nor humoral rejection was detected. The blood tacrolimus concentration was higher than usual at that time; thus, tacrolimus dosage was reduced. Myocardial hypertrophy completely resolved upon reducing the target concentration of tacrolimus and did not recur, as confirmed at echocardiography and myocardial biopsy. Thus, we conclude that tacrolimus induces reversible myocardial hypertrophy. In patients receiving tacrolimus therapy, blood concentration should be carefully controlled and extreme attention paid to cardiac involvement.

Comparison of unilateral pallidotomy and subthalamotomy findings in advanced idiopathic Parkinson's disease.

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)


A prospective, randomized, double-blind pilot study to compare the results of stereotactic unilateral pallidotomy and subthalamotomy in advanced idiopathic Parkinson's disease (PD) refractory to medical treatment was designed. Ten consecutive patients (mean age, 58.4 +/- 6.8 years; 7 men, 3 women) with similar characteristics at the duration of disease (mean disease time, 8.4 +/- 3.5 years), disabling motor fluctuations (Hoehn _ Yahr stage 3-5 in off-drug phases) and levodopa-induced dyskinesias were selected. All patients had bilateral symptoms and their levodopa equivalent dosing were analysed. Six patients were operated on in the globus pallidus interna (GPi) and four in the subthalamic nucleus (STN). Clinical evaluation included the use of the Unified Parkinson's Disease Rating Scale (UPDRS), Hoehn_Yahr score and Schwab England activities of daily living (ADL) score in 'on'- and 'off'-drug conditions before surgery and 6 months after surgery. There was statistically significant improvement in all contralateral major parkinsonian motor signs in all patients followed for 6 months. Levodopa equivalent daily intake was significantly reduced in the STN group. Changes in UPDRS, Hoehn _ Yahr and Schwab England ADL scores were similar in both groups. Cognitive functions were unchanged in both groups. Complications were observed in two patients: one had a left homonymous hemianopsia after pallidotomy and another one developed left hemiballistic movements 3 days after subthalamotomy which partly improved within 1 month with Valproate 1000 mg/day. The findings of this study suggest that lesions of the unilateral STN and GPi are equally effective treatment for patients with advanced PD refractory to medical treatment.

Pathological processes of the KIDNEY without inflammatory or neoplastic components. Nephrosis may be a primary disorder or secondary complication of other diseases. It is characterized by the NEPHROTIC SYNDROME indicating the presence of PROTEINURIA and HYPOALBUMINEMIA with accompanying EDEMA.


We investigated the effects of antithrombin, a plasma inhibitor of coagulation factors, in rats with puromycin aminonucleoside-induced nephrosis, which is an experimental model of human nephrotic syndrome. Antithrombin (50 or 500 IU/kg/i.v.) was administered to rats once a day for 10 days immediately after the injection of puromycin aminonucleoside (50 mg/kg/i.v.). Treatment with antithrombin attenuated the puromycin aminonucleoside-induced hematological abnormalities. Puromycin aminonucleoside-induced renal dysfunction and hyperlipidemia were also suppressed. Histopathological examination revealed severe renal damage such as proteinaceous casts in tubuli and tubular expansion in the kidney of control rats, while an improvement of the damage was seen in antithrombin-treated rats. In addition, antithrombin treatment markedly suppressed puromycin aminonucleoside-induced apoptosis of renal tubular epithelial cells. Furthermore, puromycin aminonucleoside-induced increases in renal cytokine content were also decreased. These findings suggest that thrombin plays an important role in the pathogenesis of puromycin aminonucleoside-induced nephrotic syndrome. Treatment with antithrombin may be clinically effective in patients with nephrotic syndrome.


A condition characterized by severe PROTEINURIA, greater than 3.5 g/day in an average adult. The substantial loss of protein in the urine results in complications such as HYPOPROTEINEMIA; generalized EDEMA; HYPERTENSION; and HYPERLIPIDEMIAS.

Amfetamine Amphetamine Sulfate (2:1) Centramina Desoxynorephedrin Fenamine Levoamphetamine Miquel Brand of Mydrial Phenamine Phenopromin Thyramine l l-Amphetamine levo levo-Amphetamine

A powerful central nervous system stimulant and sympathomimetic. Amphetamine has multiple mechanisms of action including blocking uptake of adrenergics and dopamine, stimulation of release of monamines, and inhibiting monoamine oxidase. Amphetamine is also a drug of abuse and a psychotomimetic. The l- and the d,l-forms are included here. The l-form has less central nervous system activity but stronger cardiovascular effects. The d-form is DEXTROAMPHETAMINE.


Transient left ventricular apical ballooning syndrome was first described in Japan as "Takotsubo cardiomyopathy." This syndrome has been identified in many other countries. Many variations of this syndrome have been recently described in the literature. One of the rarest is the reverse type of this syndrome, with hyperdynamic apex and complete akinesia of the base (as opposed to the classic apical ballooning). In this article, we report an interesting case of a young woman who presented with this rare type of reverse apical ballooning syndrome occurring after amphetamine use. This report is followed by review of the literature.


Attenuated disruption of prepulse inhibition by dopaminergic stimulation after maternal deprivation and adolescent corticosterone treatment in rats.

An adrenocortical steroid that has modest but significant activities as a mineralocorticoid and a glucocorticoid. (From Goodman and Gilman's The Pharmacological Basis of Therapeutics, 8th ed, p1437)


The development of schizophrenia may include an early neurodevelopmental stress component which increases vulnerability to later stressful life events, in combination leading to overt disease. We investigated the effect of an early stress, in the form of maternal deprivation, combined with a later stress, simulated by chronic periadolescent corticosterone treatment, on behaviour in rats. Acute treatment with apomorphine caused disruption of prepulse inhibition (PPI) in controls and in rats that had undergone either maternal deprivation or corticosterone treatment, but was surprisingly absent in rats that had undergone the combined early and late stress. Amphetamine treatment significantly disrupted PPI in both non-deprived groups, but was absent in both maternally deprived groups. The serotonin-1A receptor agonist, 8-OH-DPAT, induced a significant disruption of PPI in all groups. Amphetamine-induced locomotor hyperactivity was similar in all groups. These results show an inhibitory interaction of early stress, caused by maternal deprivation, combined with 'adolescent' stress, simulated by corticosterone treatment, on dopaminergic regulation of PPI. The altered effects of apomorphine and amphetamine could indicate differential changes in dopamine receptor signalling leading to functional desensitisation, or altered modulation of sensory gating in the nucleus accumbens by limbic structures such as the hippocampus.

Loss of functional activity and trophic degeneration of nerve axons and their terminal arborizations following the destruction of their cells of origin or interruption of their continuity with these cells. The pathology is characteristic of neurodegenerative diseases. Often the process of nerve degeneration is studied in research on neuroanatomical localization and correlation of the neurophysiology of neural pathways.


Iron accumulation is considered to be involved in the pathogenesis of Parkinson's disease. To demonstrate the relationship between peripheral iron overload and dopaminergic neuron loss in rat substantia nigra (SN), in the present study we used fast cyclic voltammetry, tyrosine hydroxylase (TH) immunohistochemistry, Perls' iron staining, and high performance liquid chromatography-electrochemical detection to study the degeneration of dopaminergic neurons and increased iron content in the SN of iron dextran overloaded animals. The findings showed that peripheral iron dextran overload increased the iron staining positive cells and reduced the number of TH-immunoreactive neurons in the SN. As a result, dopamine release and content, as well as its metabolites contents were decreased in caudate putamen. Even more dramatic changes were found in chronic overload group. These results suggest that peripheral iron dextran can increase the iron level in the SN, where excessive iron causes the degeneration of dopaminergic neurons. The chronic iron overload may be more destructive to dopaminergic neurons than the acute iron overload.

Erythema elevatum diutinum Extracellular cholesterosis Leukocytoclastic vasculitis


Skin reactions associated with oral coumarin-derived anticoagulants are an uncommon occurrence. Leukocytoclastic vasculitis (LV) is primarily a cutaneous small vessel vasculitis, though systemic involvement may be encountered. We report 4 patients with late-onset LV probably due to warfarin. All 4 patients presented with skin eruptions that developed after receiving warfarin for several years. The results of skin lesion biopsies were available in 3 patients, confirming LV Cutaneous lesions resolved in all patients after warfarin was discontinued. In 2 of the 4 patients, rechallenge with warfarin led to recurrence of the lesions. LV may be a late-onset adverse reaction associated with warfarin therapy.

Cord Ischemia Spinal Ischemias Experimental Ischemic Myelopathies Myelopathy

Reduced blood flow to the spinal cord which is supplied by the anterior spinal artery and the paired posterior spinal arteries. This condition may be associated with ARTERIOSCLEROSIS, trauma, emboli, diseases of the aorta, and other disorders. Prolonged ischemia may lead to INFARCTION of spinal cord tissue.


We investigated the relationship between the degeneration of spinal motor neurons and activation of N-methyl-d-aspartate (NMDA) receptors after neuraxial morphine following a noninjurious interval of aortic occlusion in rats. Spinal cord ischemia was induced by aortic occlusion for 6 min with a balloon catheter. In a microdialysis study, 10 muL of saline (group C; n = 8) or 30 mug of morphine (group M; n = 8) was injected intrathecally (IT) 0.5 h after reflow, and 30 mug of morphine (group SM; n = 8) or 10 muL of saline (group SC; n = 8) was injected IT 0.5 h after sham operation. Microdialysis samples were collected preischemia, before IT injection, and at 2, 4, 8, 24, and 48 h of reperfusion (after IT injection). Second, we investigated the effect of IT MK-801 (30 mug) on the histopathologic changes in the spinal cord after morphine-induced spastic paraparesis. After IT morphine, the cerebrospinal fluid (CSF) glutamate concentration was increased in group M relative to both baseline and group C (P < 0.05). This increase persisted for 8 hrs. IT MK-801 significantly reduced the number of dark-stained alpha-motoneurons after morphine-induced spastic paraparesis compared with the saline group. These data indicate that IT morphine induces spastic paraparesis with a concomitant increase in CSF glutamate, which is involved in NMDA receptor activation. We suggest that opioids may be neurotoxic in the setting of spinal cord ischemia via NMDA receptor activation.

Sodium channel beta-subunits modulate channel gating, assembly, and cell surface expression in heterologous cell systems. We generated beta2(-/-) mice to investigate the role of beta2 in control of sodium channel density, localization, and function in neurons in vivo. Measurements of [(3)H]saxitoxin (STX) binding showed a significant reduction in the level of plasma membrane sodium channels in beta2(-/-) neurons. The loss of beta2 resulted in negative shifts in the voltage dependence of inactivation as well as significant decreases in sodium current density in acutely dissociated hippocampal neurons. The integral of the compound action potential in optic nerve was significantly reduced, and the threshold for action potential generation was increased, indicating a reduction in the level of functional plasma membrane sodium channels. In contrast, the conduction velocity, the number and size of axons in the optic nerve, and the specific localization of Na(v)1.6 channels in the nodes of Ranvier were unchanged. beta2(-/-) mice displayed increased susceptibility to seizures, as indicated by reduced latency and threshold for pilocarpine-induced seizures, but seemed normal in other neurological tests. Our observations show that beta2-subunits play an important role in the regulation of sodium channel density and function in neurons in vivo and are required for normal action potential generation and control of excitability.

Screening for stimulant use in adult emergency department seizure patients.


OBJECTIVE: The objective of this study was to determine the prevalence of positive plasma drug screening for cocaine or amphetamine in adult emergency department seizure patients. METHODS: This prospective study evaluated consecutive eligible seizure patients who had a plasma sample collected as part of their clinical evaluation. Plasma was tested for amphetamine and the cocaine metabolite benzoylecgonine using enzyme-mediated immunoassay methodology. Plasma samples with benzoylecgonine greater than 150 ng/mL or an amphetamine greater than 500 ng/mL were defined as positive. Patient demographics, history of underlying drug or alcohol-related seizure disorder, estimated time from seizure to sample collection, history or suspicion of cocaine or amphetamine abuse, results of clinical urine testing for drugs of abuse, and assay results were recorded without patient identifiers. RESULTS: Fourteen of 248 (5.6%, 95% CI 2.7%-8.5%) plasma samples were positive by immunoassay testing for benzoylecgonine and no samples (0%, 95% CI 0-1.2%) were positive for amphetamine. Positive test results were more common in patient visits where there was a history or suspicion of cocaine or amphetamine abuse (p < 0.0005). CONCLUSIONS: During this study period, routine plasma screening for cocaine and amphetamines in adult seizure patients had a low yield. As a result, routine plasma screening would yield few cases of stimulant drug in which there was neither a history nor suspicion of drug abuse in this population.

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.

Abuse Drug Substance Abuses Addiction Dependence Disorder Use Habituation Disorders Organic Mental Induced Substance-Induced Substance-Related


The objective of this study was to explore the functional anatomy of the globus pallidus internus (GPi) by studying the effects of unilateral pallidotomy on parkinsonian 'off' signs and levodopa-induced dyskinesias (LID). We found significant positive correlations between the preoperative levodopa responsiveness of motor signs and the levodopa responsiveness of scores in timed tests (Core Assessment Program for Intracerebral Transplantations) in the contralateral limbs and the improvement in these scores after surgery, whereas there was no correlation with the improvement in LID. We also found a highly significant correlation (P: < 0.0001, r = 0.8) between the volume of the ventral lesion in the GPi and the improvement in LID in the contralateral limbs, whereas there was no correlation between the ventral volume and the improvement in parkinsonian 'off' signs. The volumes of the total lesion cylinder and the dorsal lesion did not correlate with the outcome of either dyskinesias or parkinsonian 'off' signs. The differential predictive value of levodopa responsiveness for the outcome of parkinsonian 'off' signs and LID and the different correlations of ventral lesion volume with dyskinesias and parkinsonian 'off' signs indicate that different anatomical or pathophysiological substrates may be responsible for the generation of parkinsonian 'off' signs and dyskinesias. Whereas cells in a wider area of the GPi may be implicated in parkinsonism, the ventral GPi seems to be crucial for the manifestation of LID. We suggest that our observations are additional proof of the functional somatotopy of the systems within the GPi that mediate parkinsonism and dyskinesias, especially along the dorsoventral trajectory used in pallidotomy. The outcome of pallidotomy in which the lesion involves the ventral and dorsal GPi could be the net effect of alteration in the activity of pathways which mediate different symptoms, and hence could be variable.

A synthetic opioid that is used as the hydrochloride. It is an opioid analgesic that is primarily a mu-opioid agonist. It has actions and uses similar to those of MORPHINE. (From Martindale, The Extra Pharmacopoeia, 30th ed, p1082-3)


Providing pain management for known opioid abusers is a challenging clinical task, in part because little is known about their pain experience and analgesic requirements. This study was designed to describe pain tolerance and analgesic response in a sample of opioid addicts stabilized in methadone-maintenance (MM) treatment (n = 60) in comparison to matched nondependent control subjects (n = 60). By using a placebo-controlled, two-way factorial design, tolerance to cold-pressor (CP) pain was examined, both before and after oral administration of therapeutic doses of common opioid (hydromorphone 2 mg) and nonsteroidal anti-inflammatory (ketorolac 10 mg) analgesic agents. Results showed that MM individuals were significantly less tolerant of CP pain than control subjects, replicating previous work. Analgesic effects were significant neither for medication nor group. These data indicate that MM opioid abusers represent a pain-intolerant subset of clinical patients. Their complaints of pain should be evaluated seriously and managed aggressively.

BACKGROUND: Although an indicator of renal tubular dysfunction, an increased urinary N-acetyl-beta-D-glucosaminidase (NAG) activity might reflect increased lysosomal activity in renal tubular cells. METHODS: Puromycin aminonucleoside (PAN) was administered to Sprague Dawley rats to induce proteinuria. Total protein, albumin, NAG activity and protein electrophoretic pattern were assessed in daily urine samples for 33 days. The morphological appearance of the kidneys was examined on days three, four, six, eight and thirty three and the NAG isoenzyme patterns on days zero, four, eight and thirty three. RESULTS: Following intravenous PAN urine volume and urine NAG activity increased significantly by day two, but returned to normal by day four. After day four all treated animals exhibited a marked rise in urine albumin, total protein excretion and NAG activity. Electrophoresis showed a generalised increase in middle and high molecular weight urine proteins from day four onwards. Protein droplets first appeared prominent in tubular cells on day four. Peak urine NAG activity and a change in NAG isoenzyme pattern coincided with both the peak proteinuria and the reduction in intracellular protein and NAG droplets (day six onwards). CONCLUSIONS: This animal model demonstrates that an increase in lysosomal turnover and hence urine NAG activity, occurs when increased protein is presented to the tubular cells. Urine NAG activity is thus a measure of altered function in the renal tubules and not simply an indicator of damage.

Estrogens, which have been associated with several types of human and animal cancers, can induce tumor angiogenesis in the pituitary of Fischer 344 rats. The mechanistic details of tumor angiogenesis induction, during estrogen carcinogenesis, are still unknown. To elucidate the role of estrogen in the regulation of tumor angiogenesis in the pituitary of female rats, the density of blood vessels was analysed using factor VIII related antigen (FVIIIRAg) immunohistochemistry and the expression of vascular endothelial growth factor/vascular permeability factor (VEGF/VPF) was examined by Western blot and immunohistochemical analysis. The expression of VEGF receptor (VEGFR-2/Flk-1/KDR) was also examined by immunohistochemistry. The results demonstrated that 17beta-estradiol (E2) induces neovascularization, as well as the growth and enlargement of blood vessels after 7 days of exposure. The high tumor angiogenic potential was associated with an elevated VEGF/VPF protein expression in the E2 exposed pituitary of ovariectomized (OVEX) rats. VEGF/VPF and FVIIIRAg immunohistochemistry and endothelial specific lectin (UEA1) binding studies, indicate that the elevation of VEGF protein expression initially occurred in both blood vessels and non-endothelial cells. After 15 days of E2 exposure, VEGF/VPF protein expression, in the non-endothelial cell population, sharply declined and was restricted to the blood vessels. The function of non-endothelial-derived VEGF is not clear. Furthermore, immunohistochemical studies demonstrated that VEGFR-2 (flk-1/KDR), expression was elevated significantly in the endothelial cells of microblood vessels after 7 days of E2 exposure. These findings suggest that over expression of VEGF and its receptor (VEGFR-2) may play an important role in the initial step of the regulation of estrogen induced tumor angiogenesis in the rat pituitary.

Muscle Disorder Disorders Muscular Disease Diseases Myopathic Condition Conditions Myopathies Myopathy

Acquired, familial, and congenital disorders of SKELETAL MUSCLE and SMOOTH MUSCLE.


A case of acute inflammatory myopathy associated with the use of pravastatin, a new hydrophilic 3-hydroxy-3 methylglutaril coenzyme A reductase inhibitor, is reported. The patient, a 69-year-old man was affected by non-insulin-dependent diabetes mellitus and hypertension. He assumed pravastatin (20 mg/day) because of hypercholesterolemia. He was admitted with acute myopathy of the lower limbs which resolved in a few days after pravastatin discontinuation. A previously unknown hypothyroidism, probably due to chronic autoimmune thyroiditis, was evidenced. Muscle biopsy (left gastrocnemius) revealed a perimysial and endomysial inflammatory infiltrate with a prevalence of CD4+ lymphocytes. While lovastatin and simvastatin have been associated with toxic myopathy, pravastatin-associated myopathy could represent a distinct, inflammatory entity.

Cardiomyopathies Primary Secondary Cardiomyopathy Disease Myocardial Diseases Myocardiopathies Myocardiopathy

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


The cardiomyopathy (CM) produced by the anticancer drug doxorubicin (DXR) (Adriamycin) provides a unique opportunity to analyze dose-effect and structure-function relationships during development of myocardial disease. We measured the degree of morphologic damage by ultrastructural examination of endomyocardial biopsy and the degree of performance abnormally by right heart catheterization in patients receiving DXR. Morphologic damage was variable but was proportional to the total cumulative DXR dose between 100 and 600 mg/m2. Performance abnormalities correlated weakly with dose, exhibited a curvilinear relationship, and had a "threshold" for expression. Catheterization abnormalities correlated well with morphologic damage (r = 0.57 to 0.78) in a subgroup of patients in whom exercise hemodynamics were measured, and this relationship also exhibited a curvilinear, threshold configuration. In DXR-CM myocardial damage is proportional to the degree of cytotoxic insult (DXR dose) while myocardial function is preserved until a critical dose or degree of damage is reached, after which myocardial performance deteriorates rapidly.
