The case of a 40-year-old patient who underwent an unsuccessful cadaver kidney transplantation and was treated with ethambutol and isoniazid is reported. A bilateral retrobulbar neuropathy with an unusual central bitemporal hemianopic scotoma was found. Ethambutol was stopped and only small improvement of the visual acuity followed. Isoniazid was discontinued later, followed by a dramatic improvement in the visual acuity. The hazards of optic nerve toxicity due to ethambutol are known. We emphasize the potential danger in the use of ethambutol and isoniazid.

Progestational agents and blood coagulation. VII. Thromboembolic and other complications of oral contraceptive therapy in relationship to pretreatment levels of blood coagulation factors: summary report of a ten-year study.

Hemorrhagic and thrombotic disorders that occur as a consequence of abnormalities in blood coagulation due to a variety of factors such as COAGULATION PROTEIN DISORDERS; BLOOD PLATELET DISORDERS; BLOOD PROTEIN DISORDERS or nutritional conditions.


Obstruction of a blood vessel (embolism) by a blood clot (THROMBUS) in the blood stream.

Compounds, usually hormonal, taken orally in order to block ovulation and prevent the occurrence of pregnancy. The hormones are generally estrogen or progesterone or both.


During a ten-year period, 348 women were studied for a total of 5,877 patient months in four separate studies relating oral contraceptives to changes in hematologic parameters. Significant increases in certain factors of the blood coagulation and fibrinolysin systems (factors I,II,VII,VIII,IX, and X and plasminogen) were observed in the treated groups. Severe complications developed in four patients. All four had an abnormal blood coagulation profile, suggesting "hypercoagulability" before initiation of therapy. Some of these findings represented the most extreme abnormalities seen in the entire group of patients; some increased further during therapy. One of these patients developed a myocardial infarction before receiving any medication, shortly after the base-line values were obtained. One patient developed retinopathy 19 months after she began therapy, and another developed thrombophlebitis after 27 months of therapy. The fourth patient developed thrombophlebitis 14 days after initiation of contraceptive therapy. All four patients were of the A or AB blood group. Previous studies suggested the possiblility of increased propensity for thromboembolic episodes in patients possessing the A antigen. It appears from these data that hematologic work-ups may be useful in women who are about to start long-term oral contraceptive therapy.

Athetoid Cerebral Palsy Atonic CP (Cerebral Palsy) Palsies Dyskinetic Dystonic-Rigid Monoplegic Congenital Diplegic Infantile Dystonic Rigid Hypotonic Mixed Quadriplegic Rolandic Type Spastic Diplegia Diplegias Little Disease Little's

A heterogeneous group of nonprogressive motor disorders caused by chronic brain injuries that originate in the prenatal period, perinatal period, or first few years of life. The four major subtypes are spastic, athetoid, ataxic, and mixed cerebral palsy, with spastic forms being the most common. The motor disorder may range from difficulties with fine motor control to severe spasticity (see MUSCLE SPASTICITY) in all limbs. Spastic diplegia (Little disease) is the most common subtype, and is characterized by spasticity that is more prominent in the legs than in the arms. Pathologically, this condition may be associated with LEUKOMALACIA, PERIVENTRICULAR. (From Dev Med Child Neurol 1998 Aug;40(8):520-7)

Clonidine is a frequently administered alpha2-adrenergic agonist which can decrease heart rate and blood pressure. We present a case of a 5-year-old child with cerebral palsy and seizure disorder, receiving clonidine for restlessness, who presented for placement of a baclofen pump. Without the knowledge of the medical personnel, the patient's mother administered three doses of clonidine during the evening before and morning of surgery to reduce anxiety. During induction of anesthesia, the patient developed bradycardia and hypotension requiring cardiac resuscitation. There are no previous reports of clonidine-associated cardiac arrest in a child undergoing induction of anesthesia.


Aura Auras Awakening Epilepsy Cryptogenic Epilepsies Epileptic Seizure Seizures Disorder Disorders Single

A disorder characterized by recurrent episodes of paroxysmal brain dysfunction due to a sudden, disorderly, and excessive neuronal discharge. Epilepsy classification systems are generally based upon: (1) clinical features of the seizure episodes (e.g., motor seizure), (2) etiology (e.g., post-traumatic), (3) anatomic site of seizure origin (e.g., frontal lobe seizure), (4) tendency to spread to other structures in the brain, and (5) temporal patterns (e.g., nocturnal epilepsy). (From Adams et al., Principles of Neurology, 6th ed, p313)

Effects of UMB24 and (+/-)-SM 21, putative sigma2-preferring antagonists, on behavioral toxic and stimulant effects of cocaine in mice.


3-alpha-tropanyl-(2-Cl)-acid phenoxybutyrate SM 21 maleate salt (3(S)-endo)-isomer SM(21) SM-21


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.


Earlier studies have demonstrated that antagonism of sigma1 receptors attenuates the convulsive, lethal, locomotor stimulatory and rewarding actions of cocaine in mice. In contrast, the contribution of sigma2 receptors is unclear because experimental tools to selectively target this subtype are unavailable. To begin addressing this need, we characterized UMB24 (1-(2-phenethyl)-4-(2-pyridyl)-piperazine) and (+/-)-SM 21 (3alpha-tropanyl-2-(4-chorophenoxy)butyrate) in receptor binding and behavioral studies. Receptor binding studies confirmed that UMB24 and (+/-)-SM 21 display preferential affinity for sigma2 over sigma1 receptors. In behavioral studies, pretreatment of Swiss Webster mice with UMB24 or (+/-)-SM 21 significantly attenuated cocaine-induced convulsions and locomotor activity, but not lethality. When administered alone, (+/-)-SM 21 produced no significant effects compared to control injections of saline, but UMB24 had locomotor depressant actions. Together, the data suggest that sigma2 receptor antagonists have the potential to attenuate some of the behavioral effects of cocaine, and further development of more selective, high affinity ligands are warranted.

A thioureylene antithyroid agent that inhibits the formation of thyroid hormones by interfering with the incorporation of iodine into tyrosyl residues of thyroglobulin. This is done by interfering with the oxidation of iodide ion and iodotyrosyl groups through inhibition of the peroxidase enzyme.


Cholestatic Jaundice Mechanical Obstructive

Jaundice, the condition with yellowish staining of the skin and mucous membranes, that is due to impaired BILE flow in the BILIARY TRACT, such as INTRAHEPATIC CHOLESTASIS, or EXTRAHEPATIC CHOLESTASIS.


Methimazole is a widely used and generally well-tolerated antithyroid agent. A 43-year-old woman had severe jaundice and itching 1 month after receiving methimazole (10 mg tid) and propranolol (20 mg tid) for treatment of hyperthyroidism. The patient continued treatment for another 4 days after the appearance of jaundice until she finished both medications. When seen at the emergency department 2 weeks later, she still had severe icterus, pruritus, and hyperbilirubinemia, formed mainly of the conjugated fraction. Methimazole-induced cholestasis was diagnosed, and propranolol therapy was resumed. Over the following 9 days, the symptoms improved and plasma bilirubin levels were normal after 12 weeks without methimazole. In rare cases within the first few weeks of therapy, this drug can cause severe and reversible cholestatic jaundice. Physicians and patients should be aware of this adverse effect so that, upon occurrence, they can discontinue methimazole therapy and avoid unnecessary invasive procedures.


A clinical manifestation of HYPERBILIRUBINEMIA, characterized by the yellowish staining of the SKIN; MUCOUS MEMBRANE; and SCLERA. Clinical jaundice usually is a sign of LIVER dysfunction.

Interstitial Nephritides Nephritis Tubulointerstitial

Inflammation of the interstitial tissue of the kidney. This term is generally used for primary inflammation of KIDNEY TUBULES and/or surrounding interstitium. For primary inflammation of glomerular interstitium, see GLOMERULONEPHRITIS. Infiltration of the inflammatory cells into the interstitial compartment results in EDEMA, increased spaces between the tubules, and tubular renal dysfunction.


Acquired Autoimmune Hemolytic Anemia Agglutinin Disease Cold Diseases Antibody Idiopathic Anemias

Acquired hemolytic anemia due to the presence of AUTOANTIBODIES which agglutinate or lyse the patient's own RED BLOOD CELLS.


Ciprofloxacin has been associated with several side effects including interstitial nephritis and hemolytic anemia. The combination of both side effects is extremely rare. In this report, we describe a case of ciprofloxacin-induced interstitial nephritis and autoimmune hemolytic anemia. Hemolytic anemia improved after stopping the drug and initiation of steroid therapy. Unfortunately, acute interstitial nephritis was irreversible and the patient developed end-stage renal disease.


Acquired Hemolytic Anemia Microangiopathic

A fatty acid with anticonvulsant properties used in the treatment of epilepsy. The mechanisms of its therapeutic actions are not well understood. It may act by increasing GAMMA-AMINOBUTYRIC ACID levels in the brain or by altering the properties of voltage dependent sodium channels.


syndrome of inappropriate secretion of antidiuretic hormone

ADH Syndrome Inappropriate Antidiuretic Hormone Secretion Vasopressin SIADH Schwartz Bartter Schwartz-Bartter of (SIADH)

A condition of HYPONATREMIA and renal salt loss attributed to overexpansion of BODY FLUIDS resulting from sustained release of ANTIDIURETIC HORMONES which stimulates renal resorption of water. It is characterized by normal KIDNEY function, high urine OSMOLALITY, low serum osmolality, and neurological dysfunction. Etiologies include ADH-producing neoplasms, injuries or diseases involving the HYPOTHALAMUS, the PITUITARY GLAND, and the LUNG. This syndrome can also be drug-induced.


We report the case of a 62-year-old man who was administered sodium valproate (VPA) and who subsequently developed the syndrome of inappropriate secretion of antidiuretic hormone (SIADH). He had been taking VPA for treatment of idiopathic generalized tonic-clonic convulsions since he was 56 years old. After substituting VPA with zonisamide, the serum sodium level returned to normal. We consider this episode of SIADH to be the result of a combination of factors including a weakness of the central nervous system and the long-term administration of VPA.


Convulsion Disorder Tonic-Clonic Disorders Syndrome Syndromes Grand Mal Tonic Clonic Convulsions Cryptogenic Epilepsy Epilepsies Seizure Familial Symptomatic Major Motor

A generalized seizure disorder characterized by recurrent major motor seizures. The initial brief tonic phase is marked by trunk flexion followed by diffuse extension of the trunk and extremities. The clonic phase features rhythmic flexor contractions of the trunk and limbs, pupillary dilation, elevations of blood pressure and pulse, urinary incontinence, and tongue biting. This is followed by a profound state of depressed consciousness (post-ictal state) which gradually improves over minutes to hours. The disorder may be cryptogenic, familial, or symptomatic (caused by an identified disease process). (From Adams et al., Principles of Neurology, 6th ed, p329)

Vasopressin in the treatment of milrinone-induced hypotension in severe heart failure.

American Pharmaceutical Brand of Vasopressin Regent Antidiuretic Hormones Monarch Parke-Davis (USP) Pitressin Vasopressins beta Hypophamine beta-Hypophamine

Antidiuretic hormones released by the NEUROHYPOPHYSIS of all vertebrates (structure varies with species) to regulate water balance and OSMOLARITY. In general, vasopressin is a nonapeptide consisting of a six-amino-acid ring with a cysteine 1 to cysteine 6 disulfide bridge or an octapeptide containing a CYSTINE. All mammals have arginine vasopressin except the pig with a lysine at position 8. Vasopressin, a vasoconstrictor, acts on the KIDNEY COLLECTING DUCTS to increase water reabsorption, increase blood volume and blood pressure.

A positive inotropic cardiotonic agent with vasodilator properties. It inhibits cAMP phosphodiesterase type 3 activity in myocardium and vascular smooth muscle. Milrinone is a derivative of amrinone and has 20-30 times the inotropic potency of amrinone.


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


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

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


The use of phosphodiesterase inhibitors such as milrinone in the treatment of severe heart failure is frequently restricted because they cause vasodilation and hypotension. In patients with decompensated heart failure with hypotension after treatment with milrinone, low doses of vasopressin restored blood pressure without inhibiting the inotropic effect of milrinone.


Halogenated anesthetics form liver adducts and antigens that cross-react with halothane-induced antibodies.

1,1,1-Trifluoro-2-Chloro-2-Bromoethane Fluothane Ftorotan Halothane Narcotan

A nonflammable, halogenated, hydrocarbon anesthetic that provides relatively rapid induction with little or no excitement. Analgesia may not be adequate. NITROUS OXIDE is often given concomitantly. Because halothane may not produce sufficient muscle relaxation, supplemental neuromuscular blocking agents may be required. (From AMA Drug Evaluations Annual, 1994, p178)


Two halogenated anesthetics, enflurane and isoflurane, have been associated with an allergic-type hepatic injury both alone and following previous exposure to halothane. Halothane hepatitis appears to involve an aberrant immune response. An antibody response to a protein-bound biotransformation product (trifluoroacetyl adduct) has been detected on halothane hepatitis patients. This study was performed to determine cross-reactivity between enflurane and isoflurane with the hypersensitivity induced by halothane. The subcellular and lobular production of hepatic neoantigens recognized by halothane-induced antibodies following enflurane and isoflurane, and the biochemical nature of these neoantigens was investigated in two animal models. Enflurane administration resulted in neoantigens detected in both the microsomal and cytosolic fraction of liver homogenates and in the centrilobular region of the liver. In the same liver, biochemical analysis detected fluorinated liver adducts that were up to 20-fold greater in guinea pigs than in rats. This supports and extends previous evidence for a mechanism by which enflurane and/or isoflurane could produce a hypersensitivity condition similar to that of halothane hepatitis either alone or subsequent to halothane administration. The guinea pig would appear to be a useful model for further investigations of the immunological response to these antigens.

Cancer of Liver the Hepatic Hepatocellular Cancers Neoplasm Neoplasms


Groups of male and female inbred Leeds strain rats were fed diets containing either 0.5% or 1.0% paracetamol by weight for up to 18 months. At the 1.0% dosage level, 20% of rats of both sexes developed neoplastic nodules of the liver, a statistically significant incidence. These rats also showed gross enlargement of their livers and an increase in foci of cellular alteration, the latter also being observed in the low dosage male rats. Papillomas of the transitional epithelium of the bladder developed in all paracetamol-treated groups, and three rats bore bladder carcinomas. However, significant yields of bladder tumours were only obtained from low dosage females and high dosage males. Additionally, 20 to 25% of paracetamol-treated rats developed hyperplasia of the bladder epithelium, which was not coincident with the presence of bladder calculi. A low yield of tumours at various other sites also arose following paracetamol feeding. An electron microscope study of the livers of paracetamol-treated rats revealed ultrastructural changes in the hepatocytes that resemble those that result from exposure to a variety of known hepatocarcinogens.

Local anesthetics that are commonly used in ophthalmic surgery (0.75% bupivacaine hydrochloride, 2.0% mepivacaine hydrochloride, and 2.0% lidocaine hydrochloride plus 1:100,000 epinephrine) were injected into the retrobulbar area of rat eyes. Controls were injected with physiological saline. All three anesthetics produced massive degeneration of the extraocular muscles. Muscle degeneration is followed by regeneration of the damaged muscle fibers. In addition to muscle damage, severe damage was also seen in harderian glands, especially after exposure to mepivacaine and lidocaine plus epinephrine. With these findings in rats, it is hypothesized that the temporary diplopia sometimes seen in patients after ophthalmic surgery might be due to anesthetic-induced damage to the extraocular muscles.

Reversal of neuroleptic-induced catalepsy by novel aryl-piperazine anxiolytic drugs.

Anochlesia Anochlesias Catalepsies Catalepsy Cerea Flexibilitas Flexibilities Waxy Flexibility

A condition characterized by inactivity, decreased responsiveness to stimuli, and a tendency to maintain an immobile posture. The limbs tend to remain in whatever position they are placed (waxy flexibility). Catalepsy may be associated with PSYCHOTIC DISORDERS (e.g., SCHIZOPHRENIA, CATATONIC), nervous system drug toxicity, and other conditions.


The novel anxiolytic drug, buspirone, reverses catalepsy induced by haloperidol. A series of aryl-piperazine analogues of buspirone and other 5-hydroxytryptaminergic agonists were tested for their ability to reverse haloperidol induced catalepsy. Those drugs with strong affinity for 5-hydroxytryptamine1a receptors were able to reverse catalepsy. Drugs with affinity for other 5-HT receptors or weak affinity were ineffective. However, inhibition of postsynaptic 5-HT receptors neither inhibited nor potentiated reversal of catalepsy and leaves open the question as to the site or mechanism for this effect.

3-(2-Aminoethyl)-1H-indol-5-ol 5 Hydroxytryptamine 5-HT 5-Hydroxytryptamine Enteramine Hippophaine Serotonin

A biochemical messenger and regulator, synthesized from the essential amino acid L-TRYPTOPHAN. In humans it is found primarily in the central nervous system, gastrointestinal tract, and blood platelets. Serotonin mediates several important physiological functions including neurotransmission, gastrointestinal motility, hemostasis, and cardiovascular integrity. Multiple receptor families (RECEPTORS, SEROTONIN) explain the broad physiological actions and distribution of this biochemical mediator.

Bradyarrhythmia Bradyarrhythmias Bradycardia Bradycardias

Cardiac arrhythmias that are characterized by excessively slow HEART RATE, usually below 50 beats per minute in human adults. They can be classified broadly into SINOATRIAL NODE dysfunction and ATRIOVENTRICULAR BLOCK.


The effects of diazepam on cardiovascular function were assessed in conscious rats. Intravenous administration of diazepam (1-30 mg kg-1) produced a dose-dependent decrease in both the mean arterial pressure and the heart rate. Also, reflex bradycardia was produced in rats by intravenous infusion of adrenaline (1.25-2.5 micrograms kg-1). Intravenous pretreatment of the rats with diazepam, although causing no change in the adrenaline-induced pressor effect, did enhance the adrenaline-induced reflex bradycardia. However, the diazepam enhancement of adrenaline-induced reflex bradycardia was antagonized by pretreatment of rats with an intravenous dose of picrotoxin (an agent blocks chloride channels by binding to sites associated with the benzodiazepine-GABA-chloride channel macromolecular complex). The data indicate that diazepam acts through the benzodiazepine-GABA-chloride channel macromolecular complex within the central nervous system to facilitate reflex bradycardia mediated through baroreceptor reflexes in response to an acute increase in arterial pressure.


A noncompetitive antagonist at GABA-A receptors and thus a convulsant. Picrotoxin blocks the GAMMA-AMINOBUTYRIC ACID-activated chloride ionophore. Although it is most often used as a research tool, it has been used as a CNS stimulant and an antidote in poisoning by CNS depressants, especially the barbiturates.

Auditory Seizure Seizures Clonic Convulsion Non Epileptic Non-Epileptic Convulsions Convulsive Focal Generalized Gustatory Jacksonian Motor Olfactory Sensory Somatosensory Tonic Tonic-Clonic Vertiginous Vestibular Visual

Clinical or subclinical disturbances of cortical function due to a sudden, abnormal, excessive, and disorganized discharge of brain cells. Clinical manifestations include abnormal motor, sensory and psychic phenomena. Recurrent seizures are usually referred to as EPILEPSY or "seizure disorder."


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.


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


The effects of carbamazepine (CBZ) treatment on local anesthetic-kindled seizures and lethality were evaluated in different stages of the kindling process and under different methods of CBZ administration. Chronic oral CBZ inhibited the development of both lidocaine- and cocaine-induced seizures, but had little effect on the fully developed local anesthetic seizures. Chronic CBZ also decreased the incidence of seizure-related mortality in the cocaine-injected rats. Acute CBZ over a range of doses (15-50 mg/kg) had no effect on completed lidocaine-kindled or acute cocaine-induced seizures. Repeated i.p. injection of CBZ (15 mg/kg) also was without effect on the development of lidocaine- or cocaine-kindled seizures. The differential effects of CBZ depending upon stage of seizure development suggest that distinct mechanisms underlie the development versus maintenance of local anesthetic-kindled seizures. The effectiveness of chronic but not repeated, intermittent injections of CBZ suggests that different biochemical consequences result from the different treatment regimens. The possible utility of chronic CBZ in preventing the development of toxic side effects in human cocaine users is suggested by these data, but remains to be directly evaluated.

Circumscribed Scleroderma Dermatosclerosis Frontal Linear en Coup de Sabre Localized Morphea Morpheas Sclerodermas

A term used to describe a variety of localized asymmetrical SKIN thickening that is similar to those of SYSTEMIC SCLERODERMA but without the disease features in the multiple internal organs and BLOOD VESSELS. Lesions may be characterized as patches or plaques (morphea), bands (linear), or nodules.


Localized scleroderma has no recognized internal organ involvement but may be disfiguring and disabling when the cutaneous lesions are extensive or affect children. There is no accepted or proven treatment for localized scleroderma. Case reports of 11 patients with severe, extensive localized scleroderma who were treated with D-penicillamine are summarized in this article. This drug was judged to have a favorable effect on the disease course in 7 (64%) of 11 patients. Improvement began within 3 to 6 months and consisted of cessation of active cutaneous lesions in all 7 patients, skin softening in 5, and more normal growth of the affected limb in 2 of 3 children. Joint stiffness and contractures also improved. The dose of D-penicillamine associated with a favorable response was as low as 2 to 5 mg/kg per day given over a period ranging from 15 to 53 months. D-Penicillamine caused nephrotic syndrome in 1 patient and milder reversible proteinuria in 3 other patients; none developed renal insufficiency. These data suggest that D-penicillamine may be effective in severe cases of localized scleroderma.

Corlopam Fenoldopam Hydrobromide Mesylate SK&F 82526 82526J SK&F-82526 SK&F-82526J SK&F82526 SK&F82526J SKF SKF-82526 SKF-82526J SKF82526 SKF82526J

A dopamine D1 receptor agonist that is used as an antihypertensive agent. It lowers blood pressure through arteriolar vasodilation.


The introduction of drugs that could induce hypotension with different pharmacological actions would be advantageous because side effects unique to a specific drug could be minimized by selecting appropriate therapy. Specific dopamine-1, (DA1) and dopamine-2 (DA2) receptor agonists are now under clinical investigation. Fenoldopam mesylate is a specific DA1 receptor agonist that lowers blood pressure by vasodilatation. The hypothesis that fenoldopam could be used to induce hypotension and preserve blood flow to the kidney was tested. Systemic aortic blood pressure and renal blood flow were measured continuously with a carotid arterial catheter and an electromagnetic flow probe respectively, in order to compare the cardiovascular and renal vascular effects of fenoldopam and sodium nitroprusside in ten dogs under halothane general anaesthesia. Mean arterial pressure was decreased 30 +/- 8 per cent from control with infusion of fenoldopam (3.4 +/- 2.0 micrograms.kg-1.min-1) and 34 +/- 4 per cent with infusion of sodium nitroprusside (5.9 micrograms.kg-1.min-1) (NS). Renal blood flow (RBF) increased during fenoldopam-induced hypotension 11 +/- 7 per cent and decreased 21 +/- 8 per cent during sodium nitroprusside-induced hypotension (P less than 0.01). Sodium nitroprusside is a non-selective arteriolar and venous vasodilator that can produce redistribution of blood flow away from the kidney during induced hypotension. Fenoldopam is a selective dopamine-1 (DA1) receptor agonist that causes vasodilatation to the kidney and other organs with DA1 receptors and preserves blood flow to the kidney during induced hypotension.

2-(2,2-diphenylcyclopropyl)-2-imidazoline Cipralan Exacor cibenzoline succinate cifenline (S)-isomer


Arrhythmia Cardiac Arrhythmias Arrythmia Dysrhythmia

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


Antiarrhythmic effects of (+)-cibenzoline and (-)-cibenzoline were examined using two canine ventricular arrhythmia models. Digitalis arrhythmia, which is suppressed by Na channel blockers, was induced by intermittent intravenous (i.v.) injection of ouabain in pentobarbital-anesthetized dogs. Adrenaline arrhythmia, which is suppressed by Ca channel blockers, was induced by adrenaline infusion in halothane-anesthetized dogs. Ten and 5 mg/kg i.v. (+)-cibenzoline suppressed digitalis- and adrenaline-induced arrhythmias, respectively. The minimum effective plasma concentrations of (+)-cibenzoline for digitalis- and adrenaline-induced arrhythmias were 1.4 +/- 0.4 and 2.0 +/- 0.6 micrograms/ml, respectively (mean +/- SD, n = 6). A lower dose of 1 mg/kg i.v. of (-)-cibenzoline suppressed the digitalis-induced arrhythmia, whereas 5 mg/kg i.v. was needed to suppress adrenaline-induced arrhythmias. The minimum effective plasma concentrations of (-)-cibenzoline for digitalis- and adrenaline-induced arrhythmia were 0.06 +/- 0.04 and 0.7 +/- 0.1 micrograms/ml, respectively (mean +/- SD, n = 6). The stronger antiarrhythmic effect of (-)-cibenzoline indicates that (-)-isomer may have an effect nearly 5-20 times stronger in suppressing Na channels, but effects of both drugs on Ca channels may be almost equipotent.

Raunervil Raupasil Rausedil Rausedyl Reserpine Serpasil Serpivite V Serp V-Serp Vangarde Brand of Vitarine

An alkaloid found in the roots of Rauwolfia serpentina and R. vomitoria. Reserpine inhibits the uptake of norepinephrine into storage vesicles resulting in depletion of catecholamines and serotonin from central and peripheral axon terminals. It has been used as an antihypertensive and an antipsychotic as well as a research tool, but its adverse effects limit its clinical use.


Effect of methanolic extract of Hibiscus rosa sinensis (100-300 mg/kg) was studied on reserpine-induced orofacial dyskinesia and neurochemical alterations. The rats were treated with intraperitoneal reserpine (1 mg/kg, ip) for 3 days every other day. On day 5, vacuous chewing movements and tongue protrusions were counted for 5 min. Reserpine treated rats significantly developed vacuous chewing movements and tongue protrusions however, coadministration of Hibiscus rosa sinensis roots extract (100, 200 and 300 mg/kg, per orally) attenuated the effects. Biochemical analysis of brain revealed that the reserpine treatment significantly increased lipid peroxidation and decreased levels of superoxide dismutase (SOD), catalase (CAT) and glutathione reductase (GSH), an index of oxidative stress process. Coadministration of extract significantly reduced the lipid peroxidation and reversed the decrease in brain SOD, CAT and GSH levels. The results of the present study suggested that Hibiscus rosa sinensis had a protective role against reserpine-induced orofacial dyskinesia and oxidative stress.

(Dictionary of Visual Science, 4th ed)


PURPOSE: Topical beta-blocker treatment is routine therapy in the management of patients with glaucoma. Therapy results in systemic absorption, however, the degree of reduction of resting and peak heart rate has not been quantified. DESIGN: This trial evaluated the effect of placebo, 0.5% aqueous timolol (timolol solution) and a 0.5% timolol suspension that forms a gel on application to the conjunctiva (timolol gellan) on the 24-hour heart rate in patients currently being treated for glaucoma to quantify the reduction in mean heart rate. METHODS: Forty-three Caucasian patients with primary open-angle glaucoma or ocular hypertension with a mean (+/-SD) age of 63 (+/-8) years were randomized and crossed over in a double-masked manner to 14 days of treatment with placebo (morning and evening in both eyes), timolol solution (morning and evening in both eyes), or timolol gellan (morning in both eyes with placebo in the evening). On the 13th day of each period, heart rate was recorded continuously during a typical, ambulant 24-hour period. RESULTS: Both timolol solution and timolol gellan reduced the mean 24-hour heart rate compared with placebo (P < or = .001), and this reduction was most pronounced during the daytime (-7.5% change in mean heart rate, -5.7 beats/min). Timolol gellan showed a numerically but not significantly smaller reduction in 24-hour heart rate, compared with timolol solution. During the night, the mean 12-hour heart rate on placebo and timolol gellan were both significantly less than on timolol solution; the difference between solution and gellan treatments was statistically significant (P = .01). CONCLUSIONS: Both timolol solution and timolol gellan decrease the mean 24-hour heart rate compared with placebo. This response was most pronounced during the active daytime period. These data quantify the modest bradycardia associated with ophthalmic beta-blocker therapy in a typical patient population on therapy for glaucoma. Although exercise performance was not assessed in this trial, reductions of this magnitude should not have substantial clinical consequences.

Apical Ballooning Syndrome Broken Heart Cardiomyopathy Stress Tako-tsubo Takotsubo Left Ventricular Syndromes Tako tsubo Transient

A transient left ventricular apical dysfunction or ballooning accompanied by electrocardiographic (ECG) T wave inversions. This abnormality is associated with high levels of CATECHOLAMINES, either administered or endogenously secreted from a tumor or during extreme stress.


The apical ballooning syndrome (ABS) is a recently described stress-mediated acute cardiac syndrome characterized by transient wall-motion abnormalities involving the apex and midventricle with hyperkinesis of the basal left ventricular (LV) segments without obstructive epicardial coronary disease. Cardiotoxicity is not an uncommon adverse effect of chemotherapeutic agents. However, there are no reports of ABS secondary to chemotherapeutic agents. We describe the case of a woman who developed the syndrome after chemotherapy for metastatic cancer. A 79-year-old woman presented with typical ischemic chest pain, elevated cardiac enzymes with significant ST-segment abnormalities on her electrocardiogram. She underwent recent chemotherapy with fluorouracil for metastatic colorectal cancer. Echocardiography revealed a wall-motion abnormality involving the apical and periapical segments which appeared akinetic. Coronary angiography revealed no obstructive coronary lesions. The patient was stabilized with medical therapy. Four weeks later she remained completely asymptomatic. Echocardiogram revealed a normal ejection fraction and a resolution of the apical akinesis. Pathogenetic mechanisms of cardiac complications in cancer patients undergoing chemotherapy include coronary vasospasm, endothelial damage and consequent thrombus formation. In our patient, both supraphysiologic levels of plasma catecholamines and stress related neuropeptides caused by cancer diagnosis as well as chemotherapy may have contributed the development of ABS.

BACKGROUND: Pain on injection of propofol is unpleasant. We hypothesized that propofol infusion pain might be prevented by infusing remifentanil before starting the propofol infusion in a clinical setting where target-controlled infusions (TCI) of both drugs were used. A prospective, randomized, double-blind, placebo-controlled trial was performed to determine the effect-site concentration (Ce) of remifentanil to prevent the pain without producing complications. METHODS: A total of 128 patients undergoing general surgery were randomly allocated to receive normal saline (control) or remifentanil to a target Ce of 2 ng ml(-1) (R2), 4 ng ml(-1) (R4), or 6 ng ml(-1) (R6) administered via TCI. After the target Ce was achieved, the infusion of propofol was started. Remifentanil-related complications were assessed during the remifentanil infusion, and pain caused by propofol was evaluated using a four-point scale during the propofol infusion. RESULTS: The incidence of pain was significantly lower in Groups R4 and R6 than in the control and R2 groups (12/32 and 6/31 vs 26/31 and 25/32, respectively, P<0.001). Pain was less severe in Groups R4 and R6 than in the control and R2 groups (P<0.001). However, both incidence and severity of pain were not different between Groups R4 and R6. No significant complications were observed during the study. CONCLUSIONS: During induction of anaesthesia with TCI of propofol and remifentanil, a significant reduction in propofol infusion pain was achieved without significant complications by prior administration of remifentanil at a target Ce of 4 ng ml(-1).

RATIONALE: Fluoxetine is a selective serotonin reuptake inhibitor antidepressant widely used by pregnant women. Epidemiological data suggest that fluoxetine exposure prenatally increases the prevalence of persistent pulmonary hypertension syndrome of the newborn. The mechanism responsible for this effect is unclear and paradoxical, considering the current evidence of a pulmonary hypertension protective fluoxetine effect in adult rodents. OBJECTIVES: To evaluate the fluoxetine effect on fetal rat pulmonary vascular smooth muscle mechanical properties and cell proliferation rate. METHODS: Pregnant rats were treated with fluoxetine (10 mg/kg) from Day 11 through Day 21 of gestation. MEASUREMENTS AND MAIN RESULTS: Fetuses were delivered by cesarean section. As compared with controls, fluoxetine exposure resulted in fetal pulmonary hypertension as evidenced by an increase in the weight ratio of the right ventricle to the left ventricle plus septum (P = 0.02) and by an increase in pulmonary arterial medial thickness (P < 0.01). Postnatal mortality was increased among experimental animals, and arterial oxygen saturation was 96 +/- 1% in 1-day-old control animals and significantly lower (P < 0.01) in fluoxetine-exposed pups (79 +/- 2%). In vitro, fluoxetine induced pulmonary arterial muscle contraction in fetal, but not adult, animals (P < 0.01) and reduced serotonin-induced contraction at both ages (P < 0.01). After in utero exposure to a low fluoxetine concentration the pulmonary arterial smooth muscle cell proliferation rate was significantly increased in fetal, but not adult, cells (P < 0.01). CONCLUSIONS: In contrast to the adult, fluoxetine exposure in utero induces pulmonary hypertension in the fetal rat as a result of a developmentally regulated increase in pulmonary vascular smooth muscle proliferation.

BACKGROUND: Methadone is prescribed to heroin addicts to decrease illicit opioid use. Prolongation of the QT interval in the ECG of patients with torsade de pointes (TdP) has been reported in methadone users. As heroin addicts sometimes faint while using illicit drugs, doctors might attribute too many episodes of syncope to illicit drug use and thereby underestimate the incidence of TdP in this special population, and the high mortality in this population may, in part, be caused by the proarrhythmic effect of methadone. METHODS: In this cross-sectional study interview, ECGs and blood samples were collected in a population of adult heroin addicts treated with methadone or buprenorphine on a daily basis. Of the patients at the Drug Addiction Service in the municipal of Copenhagen, 450 (approximately 52%) were included. The QT interval was estimated from 12 lead ECGs. All participants were interviewed about any experience of syncope. The association between opioid dose and QT, and methadone dose and reporting of syncope was assessed using multivariate linear regression and logistic regression, respectively. RESULTS: Methadone dose was associated with longer QT interval of 0.140 ms/mg (p = 0.002). No association between buprenorphine and QTc was found. Among the subjects treated with methadone, 28% men and 32% women had prolonged QTc interval. None of the subjects treated with buprenorphine had QTc interval >0.440 s((1/2)). A 50 mg higher methadone dose was associated with a 1.2 (95% CI 1.1 to 1.4) times higher odds for syncope. CONCLUSIONS: Methadone is associated with QT prolongation and higher reporting of syncope in a population of heroin addicts.


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.

A derivative of the opioid alkaloid THEBAINE that is a more potent and longer lasting analgesic than MORPHINE. It appears to act as a partial agonist at mu and kappa opioid receptors and as an antagonist at delta receptors. The lack of delta-agonist activity has been suggested to account for the observation that buprenorphine tolerance may not develop with chronic use.

The central nervous system toxicity of high-dose cytosine arabinoside is well recognized, but the toxicity of cytosine arabinoside in the peripheral nervous system has been infrequently reported. A 49-year-old Japanese man was diagnosed with acute myeloid leukemia. After he achieved complete remission, he received high-dose cytosine arabinoside treatment (2 g/m2 twice a day for 5 days; total, 20 g/m2) as consolidation therapy. The first course of high-dose cytosine arabinoside resulted in no unusual symptoms, but on day 21 of the second course of treatment, the patient complained of numbness in his right foot. Electromyogram and nerve-conduction studies showed peripheral neuropathy in both peroneal nerves. This neuropathy was gradually resolving; however, after the patient received allogeneic bone marrow transplantation, the symptoms worsened, with the development of graft-versus-host disease, and the symptoms subsequently responded to methylprednisolone. Although the mechanisms of peripheral neuropathy are still unclear, high-dose cytosine arabinoside is a therapy that is potentially toxic to the peripheral nervous system, and auto/alloimmunity may play an important role in these mechanisms.

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.


To assess the antioxidant effects of atorvastatin (atorva) on dexamethasone (dex)-induced hypertension, 60 male Sprague-Dawley rats were treated with atorva 30 mg/kg/day or tap water for 15 days. Dex increased systolic blood pressure (SBP) from 109 +/- 1.8 to 135 +/- 0.6 mmHg and plasma superoxide (5711 +/- 284.9 saline, 7931 +/- 392.8 U/ml dex, P < 0.001). In this prevention study, SBP in the atorva + dex group was increased from 115 +/- 0.4 to 124 +/- 1.5 mmHg, but this was significantly lower than in the dex-only group (P' < 0.05). Atorva reversed dex-induced hypertension (129 +/- 0.6 mmHg, vs. 135 +/- 0.6 mmHg P' < 0.05) and decreased plasma superoxide (7931 +/- 392.8 dex, 1187 +/- 441.2 atorva + dex, P < 0.0001). Plasma nitrate/nitrite (NOx) was decreased in dex-treated rats compared to saline-treated rats (11.2 +/- 1.08 microm, 15.3 +/- 1.17 microm, respectively, P < 0.05). Atorva affected neither plasma NOx nor thymus weight. Thus, atorvastatin prevented and reversed dexamethasone-induced hypertension in the rat.

Cellcept Mycophenolate Sodium Myfortic RS 61443 RS-61443 mycophenolate mofetil hydrochloride mycophenolic acid morpholinoethyl ester


Calcineurin inhibitors, such as cyclosporine and tacrolimus, have been available for almost 20 years. Although these drugs are highly effective and represent the mainstay of transplant immunosuppression, they are associated with acute and chronic nephrotoxicity. Acute nephrotoxicity, which occurs in the early period after transplantation, leads to a higher rate of dialysis, and chronic nephrotoxicity may eventually result in graft loss. Acute and chronic nephrotoxicity is becoming more common as the use of marginal kidneys for transplantation increases. Two recently available immunosuppressive agents, mycophenolate mofetil and sirolimus (rapamycin), have no nephrotoxicity. The use of these drugs in combination with other agents has led to the development of new paradigms of immunosuppressive therapy. This paper reviews the results of clinical trials that have investigated these new approaches to immunosuppression in renal transplant recipients.

Benign Neoplasm Neoplasms Cancer Cancers Neoplasia Tumor Tumors

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


The aim of this study was to examine the impact of anemia prevention by recombinant human erythropoietin (rHuEPO) treatment on the cytotoxicity of cyclophosphamide in solid experimental tumors. Anemia was induced using a single dose of carboplatin (50 mg/kg i.v.) resulting in a long-lasting reduction (30%) of the hemoglobin concentration. In a second group, the development of anemia was prevented by rHuEPO (1000 IU/kg) administered s.c. three times/week starting 7 days before carboplatin application. Four days after carboplatin treatment, tumors (DS-sarcoma of the rat) were implanted s.c. onto the hind food dorsum. Neither carboplatin nor rHuEPO treatment influenced tumor growth rate per se. When tumors were treated with a single dose of cyclophosphamide (60 mg/kg i.p.) 5 days after implantation, a growth delay with a subsequent regrowth of the tumors was observed. In the anemia group, the growth delay was significantly shorter compared with nonanemic controls (13.3 days versus 8.6 days). In the group where anemia was prevented by rHuEPO treatment, growth delay was comparable with that of nonanemic controls (13.3 days). These results suggest that chemotherapy-induced anemia reduces cytotoxicity of cyclophosphamide in tumors, whereas correction of anemia by rHuEPO treatment (epoetin alpha) increases the sensitivity, probably as a result of an improved oxygen supply to tumor tissue.

The effects of N-nitro-L-arginine-methyl ester (L-NAME) a nitric oxide (NO) synthase inhibitor and L-arginine, a NO precursor, were investigated on lidocaine-induced convulsions. In the first experiment, four groups of mice received physiological saline (0.9%), L-arginine (300 mg/kg, i.p.), L-NAME (100 mg/kg, i.p.) and diazepam (2 mg/kg), respectively. Thirty minutes after these injections, all mice received lidocaine (50 mg/kg, i.p.). In the second experiment, four groups of mice received similar treatment in the first experiment, and 30 min after these injections, all mice received a higher dose of lidocaine (80 mg/kg). L-NAME (100 mg/kg, i.p.) and diazepam (2 mg/kg) significantly decreased the incidence of lidocaine (50 mg/kg)-induced convulsions. In contrast, the L-arginine treatment increased the incidence of lidocaine (80 mg/kg, i.p.)-induced convulsions significantly. These results may suggest that NO is a proconvulsant mediator in lidocaine-induced convulsions.

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).


STUDY OBJECTIVE: To determine the effect of metoprolol on dobutamine stress testing with technetium-99m sestamibi single-photon emission computed tomography imaging and ST-segment monitoring, and to assess the impact of intravenous glucagon on metoprolol's effects. DESIGN: Randomized, double-blind, placebo-controlled trial. SETTING: Community hospital. PATIENTS: Twenty-two patients with known reversible perfusion defects. INTERVENTION: Patients underwent dobutamine stress tests per standard protocol. Before dobutamine was begun, no therapy was given during the first visit, and patients were randomized on subsequent visits to receive metoprolol or metoprolol plus glucagon 1 mg. Metoprolol was dosed to achieve a resting predobutamine heart rate below 65 beats/minute or a total intravenous dose of 20 mg. MEASUREMENTS AND MAIN RESULTS: Metoprolol reduced maximum heart rate 31%, summed stress scores 29%, and summed difference scores 43% versus control. Metoprolol plus glucagon also reduced the maximum heart rate 29% versus control. Summed stress and summed difference scores were not significantly reduced, although they were 18% and 30% lower, respectively, than control. No significant differences were found in any parameter between metoprolol and metoprolol-glucagon. CONCLUSION: During dobutamine stress testing, metoprolol attenuates or eliminates evidence of myocardial ischemia. Glucagon 1 mg, although somewhat effective, does not correct this effect to the extent that it can be administered clinically.
