Almirall Brand of Amlodipine Besilate Besylate Maleate (1:1) (+-)-Isomer (R)-Isomer (S)-Isomer Amlodis Amlor Astudal Eczacibasi besilate Istin Mack Norvasc Pfizer

A long-acting dihydropyridine calcium channel blocker. It is effective in the treatment of ANGINA PECTORIS and HYPERTENSION.


A very rare side-effect of amlodipine is dysguesia. A review of the literature produced only one case. We report a case about a female with essential hypertension on drug treatment with amlodipine developed loss of taste sensation. Condition moderately improved on stoppage of the drug for 25 days. We conclude that amlodipine can cause dysguesia. Here, we describe the clinical presentation and review the relevant literature on amlodipine and dysguesia.

Rhabdomyolysis in association with simvastatin and dosage increment in clarithromycin.

Necrosis or disintegration of skeletal muscle often followed by myoglobinuria.


MK 733 MK-733 MK733 Simvastatin Synvinolin Zocor

A derivative of LOVASTATIN and potent competitive inhibitor of 3-hydroxy-3-methylglutaryl coenzyme A reductase (HYDROXYMETHYLGLUTARYL COA REDUCTASES), which is the rate-limiting enzyme in cholesterol biosynthesis. It may also interfere with steroid hormone production. Due to the induction of hepatic LDL RECEPTORS, it increases breakdown of LDL CHOLESTEROL.


6-O-Methylerythromycin A 56268 A-56268 A56268 Biaxin Clarithromycin TE 031 TE-031 TE031

A semisynthetic macrolide antibiotic derived from ERYTHROMYCIN that is active against a variety of microorganisms. It can inhibit PROTEIN SYNTHESIS in BACTERIA by reversibly binding to the 50S ribosomal subunits. This inhibits the translocation of aminoacyl transfer-RNA and prevents peptide chain elongation.


Clarithromycin is the most documented cytochrome P450 3A4 (CYP3A4) inhibitor to cause an adverse interaction with simvastatin. This particular case is of interest as rhabdomyolysis only occurred after an increase in the dose of clarithromycin. The patient developed raised cardiac biomarkers without any obvious cardiac issues, a phenomenon that has been linked to rhabdomyolysis previously. To date, there has been no reported effect of rhabdomyolysis on the structure and function of cardiac muscle. Clinicians need to be aware of prescribing concomitant medications that increase the risk of myopathy or inhibit the CYP3A4 enzyme. Our case suggests that troponin elevation could be associated with statin induced rhabdomyolysis, which may warrant further studies.

Characterization of a novel BCHE "silent" allele: point mutation (p.Val204Asp) causes loss of activity and prolonged apnea with suxamethonium.

A transient absence of spontaneous respiration.


Anectine Bromide Suxamethonium Celocurine Dibromide Succinylcholine Dichloride Diiodide Diperchlorate Ditilin Listenon Lysthenon Myorelaxin Quelicin Succicuran Chloride Di H2O Di-H2O Iodide Succinyldicholine

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


Butyrylcholinesterase deficiency is characterized by prolonged apnea after the use of muscle relaxants (suxamethonium or mivacurium) in patients who have mutations in the BCHE gene. Here, we report a case of prolonged neuromuscular block after administration of suxamethonium leading to the discovery of a novel BCHE variant (c.695T>A, p.Val204Asp). Inhibition studies, kinetic analysis and molecular dynamics were undertaken to understand how this mutation disrupts the catalytic triad and determines a "silent" phenotype. Low activity of patient plasma butyrylcholinesterase with butyrylthiocholine (BTC) and benzoylcholine, and values of dibucaine and fluoride numbers fit with heterozygous atypical silent genotype. Electrophoretic analysis of plasma BChE of the proband and his mother showed that patient has a reduced amount of tetrameric enzyme in plasma and that minor fast-moving BChE components: monomer, dimer, and monomer-albumin conjugate are missing. Kinetic analysis showed that the p.Val204Asp/p.Asp70Gly-p.Ala539Thr BChE displays a pure Michaelian behavior with BTC as the substrate. Both catalytic parameters Km = 265 uM for BTC, two times higher than that of the atypical enzyme, and a low Vmax are consistent with the absence of activity against suxamethonium. Molecular dynamic (MD) simulations showed that the overall effect of the mutation p.Val204Asp is disruption of hydrogen bonding between Gln223 and Glu441, leading Ser198 and His438 to move away from each other with subsequent disruption of the catalytic triad functionality regardless of the type of substrate. MD also showed that the enzyme volume is increased, suggesting a pre-denaturation state. This fits with the reduced concentration of p.Ala204Asp/p.Asp70Gly-p.Ala539Thr tetrameric enzyme in the plasma and non-detectable fast moving-bands on electrophoresis gels.

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 present study was designed to investigate the cardioprotective effects of betaine on acute myocardial ischemia induced experimentally in rats focusing on regulation of signal transducer and activator of transcription 3 (STAT3) and apoptotic pathways as the potential mechanism underlying the drug effect. Male Sprague Dawley rats were treated with betaine (100, 200, and 400 mg/kg) orally for 40 days. Acute myocardial ischemic injury was induced in rats by subcutaneous injection of isoproterenol (85 mg/kg), for two consecutive days. Serum cardiac marker enzyme, histopathological variables and expression of protein levels were analyzed. Oral administration of betaine (200 and 400 mg/kg) significantly reduced the level of cardiac marker enzyme in the serum and prevented left ventricular remodeling. Western blot analysis showed that isoproterenol-induced phosphorylation of STAT3 was maintained or further enhanced by betaine treatment in myocardium. Furthermore, betaine (200 and 400 mg/kg) treatment increased the ventricular expression of Bcl-2 and reduced the level of Bax, therefore causing a significant increase in the ratio of Bcl-2/Bax. The protective role of betaine on myocardial damage was further confirmed by histopathological examination. In summary, our results showed that betaine pretreatment attenuated isoproterenol-induced acute myocardial ischemia via the regulation of STAT3 and apoptotic pathways.


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).


Cardiac Remodeling Ventricular Remodelings Left Ventricle Myocardial

The cells may be uniform or markedly pleomorphic, or form GIANT CELLS. Several classification schemes have been suggested.


OBJECTIVE: Quetiapine is a dibenzothiazepine derivative, similar to clozapine, which has the highest risk of causing blood dyscrasias, especially neutropenia. There are some case reports about this side effect of quetiapine, but possible risk factors are seldom discussed and identified. A case of a patient with hepatocellular carcinoma that developed neutropenia after treatment with quetiapine is described here. CASE REPORT: A 62-year-old Taiwanese widow with bipolar disorder was diagnosed with hepatocellular carcinoma at age 60. She developed leucopenia after being treated with quetiapine. After quetiapine was discontinued, her white blood cell count returned to normal. CONCLUSIONS: Although neutropenia is not a common side effect of quetiapine, physicians should be cautious about its presentation and associated risk factors. Hepatic dysfunction may be one of the possible risk factors, and concomitant fever may be a diagnostic marker for adverse reaction to quetiapine.


A tricylic dibenzodiazepine, classified as an atypical antipsychotic agent. It binds several types of central nervous system receptors, and displays a unique pharmacological profile. Clozapine is a serotonin antagonist, with strong binding to 5-HT 2A/2C receptor subtype. It also displays strong affinity to several dopaminergic receptors, but shows only weak antagonism at the dopamine D2 receptor, a receptor commonly thought to modulate neuroleptic activity. Agranulocytosis is a major adverse effect associated with administration of this agent.

Most steroids also have two methyl groups and an aliphatic side-chain attached to the nucleus. (From Hawley's Condensed Chemical Dictionary, 11th ed)


BACKGROUND AND OBJECTIVES: This report aimed to present a case of lateral antebrachial cutaneous neuropathy (LACNP) that occurred after a steroid injection in the lateral epicondyle to treat lateral epicondylitis in a 40-year-old woman. MATERIAL AND METHOD: A 40-year-old woman presented with decreased sensation and paresthesia over her right lateral forearm; the paresthesia had occurred after a steroid injection in the right lateral epicondyle 3 months before. Her sensation of light touch and pain was diminished over the lateral side of the right forearm and wrist area. RESULTS: The sensory action potential amplitude of the right lateral antebrachial cutaneous nerve (LACN) (6.2 uV) was lower than that of the left (13.1 uV). The difference of amplitude between both sides was significant because there was more than a 50% reduction. She was diagnosed with right LACNP (mainly axonal involvement) on the basis of the clinical manifestation and the electrodiagnostic findings. Her symptoms improved through physical therapy but persisted to some degree. CONCLUSION: This report describes the case of a woman with LACNP that developed after a steroid injection for the treatment of lateral epicondylitis. An electrodiagnostic study, including a nerve conduction study of the LACN, was helpful to diagnose right LACNP and to find the passage of the LACN on the lateral epicondyle.

An element with atomic symbol O, atomic number 8, and atomic weight [15.99903; 15.99977]. It is the most abundant element on earth and essential for respiration.


The potential protective effect of the dietary antioxidant curcumin (120 mg/Kg/day for 6 days) against the renal injury induced by maleate was evaluated. Tubular proteinuria and oxidative stress were induced by a single injection of maleate (400 mg/kg) in rats. Maleate-induced renal injury included increase in renal vascular resistance and in the urinary excretion of total protein, glucose, sodium, neutrophil gelatinase-associated lipocalin (NGAL) and N-acetyl b-D-glucosaminidase (NAG), upregulation of kidney injury molecule (KIM)-1, decrease in renal blood flow and claudin-2 expression besides of necrosis and apoptosis of tubular cells on 24 h. Oxidative stress was determined by measuring the oxidation of lipids and proteins and diminution in renal Nrf2 levels. Studies were also conducted in renal epithelial LLC-PK1 cells and in mitochondria isolated from kidneys of all the experimental groups. Maleate induced cell damage and reactive oxygen species (ROS) production in LLC-PK1 cells in culture. In addition, maleate treatment reduced oxygen consumption in ADP-stimulated mitochondria and diminished respiratory control index when using malate/glutamate as substrate. The activities of both complex I and aconitase were also diminished. All the above-described alterations were prevented by curcumin. It is concluded that curcumin is able to attenuate in vivo maleate-induced nephropathy and in vitro cell damage. The in vivo protection was associated to the prevention of oxidative stress and preservation of mitochondrial oxygen consumption and activity of respiratory complex I, and the in vitro protection was associated to the prevention of ROS production.

OBJECTIVE: Diazinon, a common organophosphate insecticide with genotoxic properties, was previously associated with lung cancer in the Agricultural Health Study (AHS) cohort, but few other epidemiological studies have examined diazinon-associated cancer risk. We used updated diazinon exposure and cancer incidence information to evaluate solid tumour risk in the AHS. METHODS: Male pesticide applicators in Iowa and North Carolina reported lifetime diazinon use at enrolment (1993-1997) and follow-up (1998-2005); cancer incidence was assessed through 2010(North Carolina)/2011(Iowa). Among applicators with usage information sufficient to evaluate exposure-response patterns, we used Poisson regression to estimate adjusted rate ratios (RRs) and 95% CI for cancer sites with >10 exposed cases for both lifetime (LT) exposure days and intensity-weighted (IW) lifetime exposure days (accounting for factors impacting exposure). RESULTS: We observed elevated lung cancer risks (N=283) among applicators with the greatest number of LT (RR=1.60; 95% CI 1.11 to 2.31; Ptrend=0.02) and IW days of diazinon use (RR=1.41; 95% CI 0.98 to 2.04; Ptrend=0.08). Kidney cancer (N=94) risks were non-significantly elevated (RRLT days=1.77; 95% CI 0.90 to 3.51; Ptrend=0.09; RRIW days 1.37; 95% CI 0.64 to 2.92; Ptrend=0.50), as were risks for aggressive prostate cancer (N=656). CONCLUSIONS: Our updated evaluation of diazinon provides additional evidence of an association with lung cancer risk. Newly identified links to kidney cancer and associations with aggressive prostate cancer require further evaluation.

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)


OBJECTIVE: This study describes associations of ozone and fine particulate matter with Parkinson's disease observed among farmers in North Carolina and Iowa. METHODS: We used logistic regression to determine the associations of these pollutants with self-reported, doctor-diagnosed Parkinson's disease. Daily predicted pollutant concentrations were used to derive surrogates of long-term exposure and link them to study participants' geocoded addresses. RESULTS: We observed positive associations of Parkinson's disease with ozone (odds ratio = 1.39; 95% CI: 0.98 to 1.98) and fine particulate matter (odds ratio = 1.34; 95% CI: 0.93 to 1.93) in North Carolina but not in Iowa. CONCLUSIONS: The plausibility of an effect of ambient concentrations of these pollutants on Parkinson's disease risk is supported by experimental data demonstrating damage to dopaminergic neurons at relevant concentrations. Additional studies are needed to address uncertainties related to confounding and to examine temporal aspects of the associations we observed.

A methylxanthine naturally occurring in some beverages and also used as a pharmacological agent. Caffeine's most notable pharmacological effect is as a central nervous system stimulant, increasing alertness and producing agitation. It also relaxes SMOOTH MUSCLE, stimulates CARDIAC MUSCLE, stimulates DIURESIS, and appears to be useful in the treatment of some types of headache. Several cellular actions of caffeine have been observed, but it is not entirely clear how each contributes to its pharmacological profile. Among the most important are inhibition of cyclic nucleotide PHOSPHODIESTERASES, antagonism of ADENOSINE RECEPTORS, and modulation of intracellular calcium handling.


UNASSIGNED: Our previous study has indicated that prenatal caffeine exposure (PCE) could induce intrauterine growth retardation (IUGR) of offspring. Recent research suggested that IUGR is a risk factor for glomerulosclerosis. However, whether PCE could induce glomerulosclerosis and its underlying mechanisms remain unknown. This study aimed to demonstrate the induction to glomerulosclerosis in adult offspring by PCE and its intrauterine programming mechanisms. A rat model of IUGR was established by PCE, male fetuses and adult offspring at the age of postnatal week 24 were euthanized. The results revealed that the adult offspring kidneys in the PCE group exhibited glomerulosclerosis as well as interstitial fibrosis, accompanied by elevated levels of serum creatinine and urine protein. Renal angiotensin II receptor type 2 (AT2R) gene expression in adult offspring was reduced by PCE, whereas the renal angiotensin II receptor type 1a (AT1aR)/AT2R expression ratio was increased. The fetal kidneys in the PCE group displayed an enlarged Bowman's space and a shrunken glomerular tuft, accompanied by a reduced cortex width and an increase in the nephrogenic zone/cortical zone ratio. Observation by electronic microscope revealed structural damage of podocytes; the reduced expression level of podocyte marker genes, nephrin and podocin, was also detected by q-PCR. Moreover, AT2R gene and protein expressions in fetal kidneys were inhibited by PCE, associated with the repression of the gene expression of glial-cell-line-derived neurotrophic factor (GDNF)/tyrosine kinase receptor (c-Ret) signaling pathway. These results demonstrated that PCE could induce dysplasia of fetal kidneys as well as glomerulosclerosis of adult offspring, and the low functional programming of renal AT2R might mediate the developmental origin of adult glomerulosclerosis.

UNASSIGNED: Epidemiological studies of 1,3-butadiene have suggest that exposures to humans are associated with chronic myeloid leukemia (CML). CML has a well-documented association with ionizing radiation, but reports of associations with chemical exposures have been questioned. Ionizing radiation is capable of inducing the requisite CML-associated t(9:22) translocation (Philadelphia chromosome) in appropriate cells in vitro but, thus far, chemicals have not shown this capacity. We have proposed that 1,3-butadiene metabolites be so tested as a reality check on the epidemiological reports. In order to conduct reliable testing in this regard, it is essential that a positive control for induction be available. We have used ionizing radiation to develop such a control. Results described here demonstrate that this agent does in fact induce pathogenic t(9:22) translocations in a human myeloid cell line in vitro, but does so at low frequencies. Conditions that will be required for studies of 1,3-butadiene are discussed.

Cancer incidence and metolachlor use in the Agricultural Health Study: An update.


UNASSIGNED: Metolachlor, a widely used herbicide, is classified as a Group C carcinogen by the U.S. Environmental Protection Agency based on increased liver neoplasms in female rats. Epidemiologic studies of the health effects of metolachlor have been limited. The Agricultural Health Study (AHS) is a prospective cohort study including licensed private and commercial pesticide applicators in Iowa and North Carolina enrolled 1993-1997. We evaluated cancer incidence through 2010/2011 (NC/IA) for 49,616 applicators, 53% of whom reported ever using metolachlor. We used Poisson regression to evaluate relations between two metrics of metolachlor use (lifetime days, intensity-weighted lifetime days) and cancer incidence. We saw no association between metolachlor use and incidence of all cancers combined (n = 5,701 with a 5-year lag) or most site-specific cancers. For liver cancer, in analyses restricted to exposed workers, elevations observed at higher categories of use were not statistically significant. However, trends for both lifetime and intensity-weighted lifetime days of metolachor use were positive and statistically significant with an unexposed reference group. A similar pattern was observed for follicular cell lymphoma, but no other lymphoma subtypes. An earlier suggestion of increased lung cancer risk at high levels of metolachlor use in this cohort was not confirmed in this update. This suggestion of an association between metolachlor and liver cancer among pesticide applicators is a novel finding and echoes observation of increased liver neoplasms in some animal studies. However, our findings for both liver cancer and follicular cell lymphoma warrant follow-up to better differentiate effects of metolachlor use from other factors.

Mechanisms Underlying Latent Disease Risk Associated with Early-Life Arsenic Exposure: Current Research Trends and Scientific Gaps.

A shiny gray element with atomic symbol As, atomic number 33, and atomic weight 75. It occurs throughout the universe, mostly in the form of metallic arsenides. Most forms are toxic. According to the Fourth Annual Report on Carcinogens (NTP 85-002, 1985), arsenic and certain arsenic compounds have been listed as known carcinogens. (From Merck Index, 11th ed)


BACKGROUND: Millions of individuals worldwide, particularly those living in rural and developing areas, are exposed to harmful levels of inorganic arsenic (iAs) in their drinking water. Inorganic As exposure during key developmental periods is associated with a variety of adverse health effects including those that are evident in adulthood. There is considerable interest in identifying the molecular mechanisms that relate early-life iAs exposure to the development of these latent diseases, particularly in relationship to cancer. OBJECTIVES: This work summarizes research on the molecular mechanisms that underlie the increased risk of cancer development in adulthood that is associated with early-life iAs exposure. DISCUSSION: Epigenetic reprogramming that imparts functional changes in gene expression, the development of cancer stem cells, and immunomodulation are plausible underlying mechanisms by which early-life iAs exposure elicits latent carcinogenic effects. CONCLUSIONS: Evidence is mounting that relates early-life iAs exposure and cancer development later in life. Future research should include animal studies that address mechanistic hypotheses and studies of human populations that integrate early-life exposure, molecular alterations, and latent disease outcomes.

On the antiarrhythmic activity of one N-substituted piperazine derivative of trans-2-amino-3-hydroxy-1, 2, 3, 4-tetrahydroanaphthalene.

1,4-piperazine Pripsen piperazine diacetate dihydrochloride hexahydrate hydrate hydrobromide hydrochloride monohydrochloride phosphate (1:1) salt sulfate tartrate (R-(R*,R*))-isomer piperazinium oleate


The antiarrhythmic activity of the compound N-(trans-3-hydroxy-1,2,3,4-tetrahydro-2-naphthyl)-N-(3-oxo-3-phenyl-2-methylpropyl)-piperazine hydrochloride, referred to as P11, is studied on anaesthesized cats and Wistar albino rats, as well as on non-anaesthesized rabbits. Four types of experimental arrhythmia are used--with BaCl2, with chloroform-adrenaline, with strophantine G and with aconitine. The compound P11 is introduced in doses of 0.25 and 0.50 mg/kg intravenously and 10 mg/kg orally. The compound manifests antiarrhythmic activity in all models of experimental arrhythmia used, causing greatest inhibition on the arrhythmia induced by chloroform-adrenaline (in 90 per cent) and with BaCl2 (in 84 per cent). The results obtained are associated with the beta-adrenoblocking and with the membrane-stabilizing action of the compound.

A heterogeneous group of inherited MYOPATHIES, characterized by wasting and weakness of the SKELETAL MUSCLE. They are categorized by the sites of MUSCLE WEAKNESS; AGE OF ONSET; and INHERITANCE PATTERNS.


We are still a long way from discovering an unequivocal pathogenetic interpretation of progressive muscular dystrophy in man. Noteworthy efforts have been made in the experimental field; a recessive autosomic form found in the mouse seems to bear the closest resemblance to the human form from the genetic point of view. Myopathy due to lack of vitamin E and myopathy induced by certain viruses have much in common anatomically and pathologically with the human form. The authors induced myodystrophy in the rat by giving it a diet lacking in vitamin E. The pharmacological characteristics of vitamin E and the degenerative changes brought about by its deficiency, especially in the muscles, are illustrated. It is thus confirmed that the histological characteristics of myopathic rat muscle induced experimentally are extraordinarily similar to those of human myopathy as confirmed during biopsies performed at the Orthopaedic Traumatological Centre, Florence. The encouraging results obtained in various authoratative departments in myopathic patients by using anabolizing steroids have encouraged the authors to investigate the beneficial effects of one anabolizing agent (Dianabol, CIBA) at high doses in rats rendered myopathic by a diet deficient in vitamin E. In this way they obtained appreciable changes in body weight (increased from 50 to 70 g after forty days at a dose of 5 mg per day of anabolizing agent), but most of all they found histological changes due to "regenerative" changes in the muscle tissue, which however maintained its myopathic characteristics in the control animals that were not treated with the anabolizing agent. The authors conclude by affirming the undoubted efficacy of the anabolizing steroids in experimental myopathic disease, but they have reservations as to the transfer of the results into the human field, where high dosage cannot be carried out continuously because of the effects of the drug on virility; because the tissue injury too often occurs at an irreversible stage vis-a-vis the "regeneration" of the muscle tissue; and finally because the dystrophic injurious agent is certainly not the lack of vitamin E but something as yet unknown.

An anticoagulant that acts by inhibiting the synthesis of vitamin K-dependent coagulation factors. Warfarin is indicated for the prophylaxis and/or treatment of venous thrombosis and its extension, pulmonary embolism, and atrial fibrillation with embolization. It is also used as an adjunct in the prophylaxis of systemic embolism after myocardial infarction. Warfarin is also used as a rodenticide.


Two mothers with heart valve prosthesis were treated with warfarin during pregnancy. In the first case a caesarean section was done one week after replacement of warfarin with heparin. The baby died of cerebral and pulmonary hemorrhage. The second mother had a male infant by caesarean section. The baby showed warfarin-induced embryopathy with nasal hypoplasia and stippled epiphyses (chondrodysplasia punctata). Nasal hypoplasia with or without stippled epiphyses has now been reported in 11 infants born to mothers treated with warfarin during the first trimester, and a causal association is probable. In view of the risks to both mother and fetus in women with prosthetic cardiac valves it is recommended that therapeutic abortion be advised as the first alternative.

Blood Pressure High Pressures Hypertension

Persistently high systemic arterial BLOOD PRESSURE. Based on multiple readings (BLOOD PRESSURE DETERMINATION), hypertension is currently defined as when SYSTOLIC PRESSURE is consistently greater than 140 mm Hg or when DIASTOLIC PRESSURE is consistently 90 mm Hg or more.


A 6-week open study of the introduction of isradipine treatment was conducted in general practice in Hong Kong. 303 Chinese patients with mild to moderate hypertension entered the study. Side effects were reported in 21% of patients and caused withdrawal from the study in 3 patients. The main side-effects were headache, dizziness, palpitation and flushing and these were not more frequent than reported in other studies with isradipine or with placebo. Supine blood pressure was reduced (P less than 0.01) from 170 +/- 20/102 +/- 6 mmHg to 153 +/- 19/92 +/- 8, 147 +/- 18/88 +/- 7 and 144 +/- 14/87 +/- 6 mmHg at 2, 4 and 6 weeks respectively in evaluable patients. Similar reductions occurred in standing blood pressure and there was no evidence of postural hypotension. Normalization and responder rates at 6 weeks were 86% and 69% respectively. Dosage was increased from 2.5 mg b.d. to 5 mg b.d. at 4 weeks in patients with diastolic blood pressure greater than 90 mmHg and their further response was greater than those remaining on 2.5 mg b.d.

A form of bronchial disorder with three distinct components: airway hyper-responsiveness (RESPIRATORY HYPERSENSITIVITY), airway INFLAMMATION, and intermittent AIRWAY OBSTRUCTION. It is characterized by spasmodic contraction of airway smooth muscle, WHEEZING, and dyspnea (DYSPNEA, PAROXYSMAL).


High doses of inhaled salbutamol produce substantial improvements in airway response in patients with asthma, and are associated with dose-dependent systemic beta-adrenoceptor responses. The purpose of the present study was to investigate whether tachyphylaxis occurs during prolonged treatment with high dose inhaled salbutamol. Twelve asthmatic patients (FEV1, 81 +/- 4% predicted), requiring only occasional inhaled beta-agonists as their sole therapy, were given a 14-day treatment with high dose inhaled salbutamol (HDS), 4,000 micrograms daily, low dose inhaled salbutamol (LDS), 800 micrograms daily, or placebo (PI) by metered-dose inhaler in a double-blind, randomized crossover design. During the 14-day run-in and during washout periods, inhaled beta-agonists were withheld and ipratropium bromide was substituted for rescue purposes. At the end of each 14-day treatment, a dose-response curve (DRC) was performed, and airway (FEV1, FEF25-75) chronotropic (HR), tremor, and metabolic (K, Glu) responses were measured at each step (from 100 to 4,000 micrograms). Treatment had no significant effect on baseline values. There were dose-dependent increases in FEV1 and FEF25-75 (p less than 0.001), and pretreatment with HDS did not displace the DRC to the right. DRC for HR (p less than 0.001), K (p less than 0.001), and Glu (p less than 0.005) were attenuated after treatment with HDS compared with PI. There were also differences between HDS and LDS for HR (p less than 0.001) and Glu (p less than 0.05) responses. Frequency and severity of subjective adverse effects were also reduced after HDS: tremor (p less than 0.001), palpitations (p less than 0.001).(ABSTRACT TRUNCATED AT 250 WORDS)

A methylxanthine naturally occurring in some beverages and also used as a pharmacological agent. Caffeine's most notable pharmacological effect is as a central nervous system stimulant, increasing alertness and producing agitation. It also relaxes SMOOTH MUSCLE, stimulates CARDIAC MUSCLE, stimulates DIURESIS, and appears to be useful in the treatment of some types of headache. Several cellular actions of caffeine have been observed, but it is not entirely clear how each contributes to its pharmacological profile. Among the most important are inhibition of cyclic nucleotide PHOSPHODIESTERASES, antagonism of ADENOSINE RECEPTORS, and modulation of intracellular calcium handling.


A type of anxiety disorder characterized by unexpected panic attacks that last minutes or, rarely, hours. Panic attacks begin with intense apprehension, fear or terror and, often, a feeling of impending doom. Symptoms experienced during a panic attack include dyspnea or sensations of being smothered; dizziness, loss of balance or faintness; choking sensations; palpitations or accelerated heart rate; shakiness; sweating; nausea or other form of abdominal distress; depersonalization or derealization; paresthesias; hot flashes or chills; chest discomfort or pain; fear of dying and fear of not being in control of oneself or going crazy. Agoraphobia may also develop. Similar to other anxiety disorders, it may be inherited as an autosomal dominant trait.


The effects of oral administration of caffeine (10 mg/kg) on behavioral ratings, somatic symptoms, blood pressure and plasma levels of 3-methoxy-4-hydroxyphenethyleneglycol (MHPG) and cortisol were determined in 17 healthy subjects and 21 patients meeting DSM-III criteria for agoraphobia with panic attacks or panic disorder. Caffeine produced significantly greater increases in subject-rated anxiety, nervousness, fear, nausea, palpitations, restlessness, and tremors in the patients compared with healthy subjects. In the patients, but not the healthy subjects, these symptoms were significantly correlated with plasma caffeine levels. Seventy-one percent of the patients reported that the behavioral effects of caffeine were similar to those experienced during panic attacks. Caffeine did not alter plasma MHPG levels in either the healthy subjects or patients. Caffeine increased plasma cortisol levels equally in the patient and healthy groups. Because caffeine is an adenosine receptor antagonist, these results suggest that some panic disorder patients may have abnormalities in neuronal systems involving adenosine. Patients with anxiety disorders may benefit by avoiding caffeine-containing foods and beverages.

Human and canine ventricular vasoactive intestinal polypeptide: decrease with heart failure.

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

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


Vasoactive intestinal polypeptide (VIP) is a systemic and coronary vasodilator that may have positive inotropic properties. Myocardial levels of VIP were assayed before and after the development of heart failure in two canine models. In the first, cobalt cardiomyopathy was induced in eight dogs; VIP (by radioimmunoassay) decreased from 35 +/- 11 pg/mg protein (mean +/- SD) to 5 +/- 4 pg/mg protein (P less than 0.05). In six dogs with doxorubicin-induced heart failure, VIP decreased from 31 +/- 7 to 11 +/- 4 pg/mg protein (P less than 0.05). In addition, VIP content of left ventricular muscle of resected failing hearts in 10 patients receiving a heart transplant was compared with the papillary muscles in 14 patients (five with rheumatic disease, nine with myxomatous degeneration) receiving mitral valve prostheses. The lowest myocardial VIP concentration was found in the hearts of patients with coronary disease (one patient receiving a transplant and three receiving mitral prostheses) (6.3 +/- 1.9 pg/mg protein). The other patients undergoing transplantation had an average ejection fraction of 17% +/- 6% and a VIP level of 8.8 +/- 3.9 pg/mg protein. The hearts without coronary artery disease (average ejection fraction of this group 62% +/- 10%) had a VIP concentration of 14.1 +/- 7.9 pg/mg protein, and this was greater than in hearts of the patients with coronary disease and the hearts of patients receiving a transplant (P less than 0.05). Myocardial catecholamines were also determined in 14 subjects; a weak correlation (r = 0.57, P less than 0.05) between the tissue concentrations of VIP and norepinephrine was noted.(ABSTRACT TRUNCATED AT 250 WORDS)

Interstrain variation in acute toxic response to caffeine among inbred mice.

A methylxanthine naturally occurring in some beverages and also used as a pharmacological agent. Caffeine's most notable pharmacological effect is as a central nervous system stimulant, increasing alertness and producing agitation. It also relaxes SMOOTH MUSCLE, stimulates CARDIAC MUSCLE, stimulates DIURESIS, and appears to be useful in the treatment of some types of headache. Several cellular actions of caffeine have been observed, but it is not entirely clear how each contributes to its pharmacological profile. Among the most important are inhibition of cyclic nucleotide PHOSPHODIESTERASES, antagonism of ADENOSINE RECEPTORS, and modulation of intracellular calcium handling.


Acute toxic dosage-dependent behavioral effects of caffeine were compared in adult males from seven inbred mouse strains (A/J, BALB/cJ, CBA/J, C3H/HeJ, C57BL/6J, DBA/2J, SWR/J). C57BL/6J, chosen as a "prototypic" mouse strain, was used to determine behavioral responses to a broad range (5-500 mg/kg) of caffeine doses. Five phenotypic characteristics--locomotor activity, righting ability, clonic seizure induction, stress-induced lethality, death without external stress--were scored at various caffeine doses in drug-naive animals under empirically optimized, rigidly constant experimental conditions. Mice (n = 12 for each point) received single IP injections of a fixed volume/g body weight of physiological saline carrier with or without caffeine in doses ranging from 125-500 mg/kg. Loss of righting ability was scored at 1, 3, 5 min post dosing and at 5 min intervals thereafter for 20 min. In the same animals the occurrence of clonic seizures was scored as to time of onset and severity for 20 min after drug administration. When these proceeded to tonic seizures, death occurred in less than 20 min. Animals surviving for 20 min were immediately stressed by a swim test in 25 degrees C water, and death-producing tonic seizures were scored for 2 min. In other animals locomotor activity was measured 15 or 60 min after caffeine administration. By any single behavioral criterion or a combination of these criteria, marked differences in response to toxic caffeine doses were observed between strains. These results indicate that behavioral toxicity testing of alkylxanthines in a single mouse strain may be misleading and suggest that toxic responses of the central nervous system to this class of compounds are genetically influenced in mammals.

Precursor of an alkylating nitrogen mustard antineoplastic and immunosuppressive agent that must be activated in the LIVER to form the active aldophosphamide. It has been used in the treatment of LYMPHOMA and LEUKEMIA. Its side effect, ALOPECIA, has been used for defleecing sheep. Cyclophosphamide may also cause sterility, birth defects, mutations, and cancer.


A 47-year-old woman with right hydroureteronephrosis due to ureterovesical junction obstruction had gross hematuria after being treated for five years wtih cyclophosphamide for cerebral vasculitis. A right nephroureterectomy was required for control of bleeding. The pathology specimen contained clinically occult invasive carcinoma of the renal pelvis. Although the ability of cyclophosphamide to cause hemorrhagic cystitis and urine cytologic abnormalities indistinguishable from high grade carcinoma is well known, it is less widely appreciated that it is also associated with carcinoma of the urinary tract. Twenty carcinomas of the urinary bladder and one carcinoma of the prostate have been reported in association with its use. The present case is the first carcinoma of the renal pelvis reported in association with cyclophosphamide treatment. It is the third urinary tract cancer reported in association with cyclophosphamide treatment for nonmalignant disease. The association of the tumor with preexisting hydroureteronephrosis suggests that stasis prolonged and intensified exposure of upper urinary tract epithelium to cyclophosphamide. Patients who are candidates for long-term cyclophosphamide treatment should be routinely evaluated for obstructive uropathy.

Abnormal enlargement or swelling of a KIDNEY due to dilation of the KIDNEY CALICES and the KIDNEY PELVIS. It is often associated with obstruction of the URETER or chronic kidney diseases that prevents normal drainage of urine into the URINARY BLADDER.

OBJECTIVE: To determine the maximum tolerated dose (MTD) of carbetocin (a long-acting synthetic analogue of oxytocin), when administered immediately after vaginal delivery at term. MATERIALS AND METHODS: Carbetocin was given as an intramuscular injection immediately after the birth of the infant in 45 healthy women with normal singleton pregnancies who delivered vaginally at term. Dosage groups of 15, 30, 50, 75, 100, 125, 150, 175 or 200 microg carbetocin were assigned to blocks of three women according to the continual reassessment method (CRM). RESULTS: All dosage groups consisted of three women, except those with 100 microg (n=6) and 200 microg (n=18). Recorded were dose-limiting adverse events: hyper- or hypotension (three), severe abdominal pain (0), vomiting (0) and retained placenta (four). Serious adverse events occurred in seven women: six cases with blood loss > or = 1000 ml, four cases of manual placenta removal, five cases of additional oxytocics administration and five cases of blood transfusion. Maximum blood loss was greatest at the upper and lower dose levels, and lowest in the 70-125 microg dose range. Four out of six cases with blood loss > or = 1000 ml occurred in the 200 microg group. The majority of additional administration of oxytocics (4/5) and blood transfusion (3/5) occurred in the dose groups of 200 microg. All retained placentae were found in the group of 200 microg. CONCLUSION: The MTD was calculated to be at 200 microg carbetocin.


A nonapeptide hormone released from the neurohypophysis (PITUITARY GLAND, POSTERIOR). It differs from VASOPRESSIN by two amino acids at residues 3 and 8. Oxytocin acts on SMOOTH MUSCLE CELLS, such as causing UTERINE CONTRACTIONS and MILK EJECTION.

A catecholamine derivative with specificity for BETA-1 ADRENERGIC RECEPTORS. It is commonly used as a cardiotonic agent after CARDIAC SURGERY and during DOBUTAMINE STRESS ECHOCARDIOGRAPHY.


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.


Pressure, burning, or numbness in the chest.


STUDY OBJECTIVE: Chest pain in the setting of cocaine use poses a diagnostic dilemma. Dobutamine stress echocardiography (DSE) is a widely available and sensitive test for evaluating cardiac ischemia. Because of the theoretical concern regarding administration of dobutamine in the setting of cocaine use, we conducted a pilot study to assess the safety of DSE in emergency department patients with cocaine-associated chest pain. METHODS: A prospective case series was conducted in the intensive diagnostic and treatment unit in the ED of an urban tertiary-care teaching hospital. Patients were eligible for DSE if they had used cocaine within 24 hours preceding the onset of chest pain and had a normal ECG and tropinin I level. Patients exhibiting signs of continuing cocaine toxicity were excluded from the study. All patients were admitted to the hospital for serial testing after the DSE testing in the intensive diagnostic and treatment unit. RESULTS: Twenty-four patients were enrolled. Two patients had inadequate resting images, one DSE was terminated because of inferior hypokinesis, another DSE was terminated because of a rate-related atrial conduction deficit, and 1 patient did not reach the target heart rate. Thus, 19 patients completed a DSE and reached their target heart rates. None of the patients experienced signs of exaggerated adrenergic response, which was defined as a systolic blood pressure of greater than 200 mm Hg or the occurrence of tachydysrhythmias (excluding sinus tachycardia). Further suggesting lack of exaggerated adrenergic response, 13 (65%) of 20 patients required supplemental atropine to reach their target heart rates. CONCLUSION: No exaggerated adrenergic response was detected when dobutamine was administered to patients with cocaine-related chest pain.

An antianginal and class III antiarrhythmic drug. It increases the duration of ventricular and atrial muscle action by inhibiting POTASSIUM CHANNELS and VOLTAGE-GATED SODIUM CHANNELS. There is a resulting decrease in heart rate and in vascular resistance.


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


The authors present a case of early (within 4 days) development of torsade de pointes (TdP) associated with oral amiodarone therapy. Consistent with other reports this case of TdP occurred in the context of multiple exacerbating factors including hypokalemia and digoxin excess. Transient prolongation of the QT during bladder irrigation prompted the episode of TdP. It is well known that bradycardia exacerbates acquired TdP. The authors speculate that the increased vagal tone during bladder irrigation, a vagal maneuver, in the context of amiodarone therapy resulted in amiodarone-induced proarrhythmia. In the absence of amiodarone therapy, a second bladder irrigation did not induce TdP despite hypokalemia and hypomagnesemia.


Hypokalemia Hypokalemias Hypopotassemia Hypopotassemias

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.

Amyloid - primary Amyloidosis Primary amyloidosis


BACKGROUND: Patients with primary systemic amyloidosis (AL) have a poor prognosis. Median survival time from standard treatments is only 17 months. High-dose intravenous melphalan followed by peripheral blood stem cell transplant (PBSCT) appears to be the most promising therapy, but treatment mortality can be high. The authors have noted the development of acute renal insufficiency immediately after melphalan conditioning. This study was undertaken to further examine its risk factors and impact on posttransplant mortality. METHODS: Consecutive AL patients who underwent PBSCT were studied retrospectively. Acute renal insufficiency (ARI) after high-dose melphalan was defined by a minimum increase of 0.5 mg/dL (44 micromol/L) in the serum creatinine level that is greater than 50% of baseline immediately after conditioning. Urine sediment score was the sum of the individual types of sediment identified on urine microscopy. RESULTS: Of the 80 patients studied, ARI developed in 18.8% of the patients after high-dose melphalan. Univariate analysis identified age, hypoalbuminemia, heavy proteinuria, diuretic use, and urine sediment score (>3) as risk factors. Age and urine sediment score remained independently significant risk factors in the multivariate analysis. Patients who had ARI after high-dose melphalan underwent dialysis more often (P = 0.007), and had a worse 1-year survival (P = 0.03). CONCLUSION: The timing of renal injury strongly suggests melphalan as the causative agent. Ongoing tubular injury may be a prerequisite for renal injury by melphalan as evidenced by the active urinary sediment. Development of ARI adversely affected the outcome after PBSCT. Effective preventive measures may help decrease the treatment mortality of PBSCT in AL patients.


A group of sporadic, familial and/or inherited, degenerative, and infectious disease processes, linked by the common theme of abnormal protein folding and deposition of AMYLOID. As the amyloid deposits enlarge they displace normal tissue structures, causing disruption of function. Various signs and symptoms depend on the location and size of the deposits.


A condition in which albumin level in blood (SERUM ALBUMIN) is below the normal range. Hypoalbuminemia may be due to decreased hepatic albumin synthesis, increased albumin catabolism, altered albumin distribution, or albumin loss through the urine (ALBUMINURIA).

INTRODUCTION: The ability to read facial expressions is essential for normal human social interaction. The aim of the present study was to conduct the first investigation of facial expression recognition performance in recreational cocaine users. MATERIALS AND METHODS: Three groups, comprised of 21 cocaine naive participants (CN),  30 occasional cocaine (OC), and 48 regular recreational cocaine (RC) users, were compared. An emotional facial expression (EFE) task consisting of a male and female face expressing six basic emotions (happiness, surprise, sadness, anger, fear, and disgust) was administered. Mean percent accuracy and latencies for correct responses across eight presentations of each basic emotion were derived. Participants were also assessed with the "Eyes task" to investigate their ability to recognize more complex emotional states and the Symptom CheckList-90-Revised to measure psychopathology. RESULTS: There were no group differences in psychopathology or "eyes task" performance, but the RC group, who otherwise had similar illicit substance use histories to the OC group, exhibited impaired fear recognition accuracy compared to the OC and CN groups. The RC group also correctly identified anger, fear, happiness, and surprise, more slowly than CN, but not OC participants. The OC group was slower than CN when correctly identifying disgust. The selective deficit in fear recognition accuracy manifested by the RC group cannot be explained by the subacute effects of cocaine, or ecstasy, because recent and less recent users of these drugs within this group were similarly impaired. Possible parallels between RC users and psychopaths with respect to impaired fear recognition, amygdala dysfunction, and etiology are discussed.

Corneal Ulcer Keratitides Ulcerative Keratitis

Loss of epithelial tissue from the surface of the cornea due to progressive erosion and necrosis of the tissue; usually caused by bacterial, fungal, or viral infection.


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.


PURPOSE: We report 4 cases of corneal ulcers associated with drug abuse. The pathogenesis of these ulcers and management of these patients are also reviewed. METHODS: Review of all cases of corneal ulcers associated with drug abuse seen at our institution from July 2006 to December 2006. RESULTS: Four patients with corneal ulcers associated with crack cocaine use were reviewed. All corneal ulcers were cultured, and the patients were admitted to the hospital for intensive topical antibiotic treatment. Each patient received comprehensive health care, including medical and substance abuse consultations. Streptococcal organisms were found in 3 cases and Capnocytophaga and Brevibacterium casei in 1 patient. The infections responded to antibiotic treatment. Two patients needed a lateral tarsorrhaphy for persistent epithelial defects. CONCLUSIONS: Aerosolized crack cocaine use can be associated with the development of corneal ulcers. Drug abuse provides additional challenges for management. Not only treatment of their infections but also the overall poor health of the patients and increased risk of noncompliance need to be addressed. Comprehensive care may provide the patient the opportunity to discontinue their substance abuse, improve their overall health, and prevent future corneal complications.

OBJECTIVE: To assess pharmacokinetics, efficacy, and tolerability of oral levetiracetam administered as an adjunct to phenobarbital treatment in cats with poorly controlled suspected idiopathic epilepsy. DESIGN-Open-label, noncomparative clinical trial. ANIMALS: 12 cats suspected to have idiopathic epilepsy that was poorly controlled with phenobarbital or that had unacceptable adverse effects when treated with phenobarbital. PROCEDURES: Cats were treated with levetiracetam (20 mg/kg [9.1 mg/lb], PO, q 8 h). After a minimum of 1 week of treatment, serum levetiracetam concentrations were measured before and 2, 4, and 6 hours after drug administration, and maximum and minimum serum concentrations and elimination half-life were calculated. Seizure frequencies before and after initiation of levetiracetam treatment were compared, and adverse effects were recorded. RESULTS: Median maximum serum levetiracetam concentration was 25.5 microg/mL, median minimum serum levetiracetam concentration was 8.3 microg/mL, and median elimination half-life was 2.9 hours. Median seizure frequency prior to treatment with levetiracetam (2.1 seizures/mo) was significantly higher than median seizure frequency after initiation of levetiracetam treatment (0.42 seizures/mo), and 7 of 10 cats were classified as having responded to levetiracetam treatment (ie, reduction in seizure frequency of >or=50%). Two cats had transient lethargy and inappetence. CONCLUSIONS AND CLINICAL RELEVANCE: Results suggested that levetiracetam is well tolerated in cats and may be useful as an adjunct to phenobarbital treatment in cats with idiopathic epilepsy.

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.
