Drugs containing ergotamine are commonly used in the treatment of migraine. Hypersensitivity to these drugs may be triggered off even with intake of recommended doses, inducing peripheral ischemia. Contributing factors to ergotism are concurrent fever, liver disease and drugs such as erythromycin or
OBJECTIVE
To compare the effects of the ergot alkaloid ergovaline with effects of ergotamine on blood pressure, heart rate, respiratory rate, and body temperature in conscious sheep.
METHODS
3 sheep with indwelling arterial catheters.
METHODS
Ergotamine and ergovaline were injected IV (20 nmol/kg),
Ergot alkaloids are considered causative agents of fescue toxicosis, a syndrome experienced by cattle consuming tall fescue (Festuca arundinacea) infected with the fungal endophyte Neotyphodium coenophialum. One sign of fescue toxicosis in cattle is severe hyperthermia. This study assessed hormonal
Tongue necrosis is a rare complication in arteritis temporalis. Our case is a 74-year-old patient who presented with weight loss, tiredness and fever during a 2-3-month period after ingestion of 2 mg ergotamine to treat her migraine. Tongue necrosis then occurred after ingestion of another 2 mg of
A 67-year-old female was evaluated in the out-patient clinic because of shortness of breath on exertion and regular spells of fever. She had been taking ergotamine tartrate to treat migraine for more than 30 years. The patient had undergone aortic-valve replacement for aortic insufficiency three
A 83-year-old woman was admitted to hospital with chest pain, fever, dry cough and palpitations. Chest X-ray revealed a pleural effusion, assumed to be caused by cardiac failure and respiratory infection. Despite treatment with antibiotics and diuretics, the pleural effusion increased on chest X-ray
Anticonvulsant hypersensitivity syndrome (AHS) is a rare, potentially fatal, idiosyncratic drug reaction characterized by fever, morbilliform rash, lymphadenopathy, hepatitis, and hematologic abnormalities. Aromatic antiepileptic agents, such as phenytoin, carbamazepine, and phenobarbital are the
The many changes in classification of cardiovascular disease during the twentieth century reflect changing etiology of diseases, clinical comprehension and technological advances. In particular, the etiology of valvular heart disease has changed dramatically in the last five decades. The significant
Molds are ubiquitous throughout the biosphere of planet earth and cause infectious, allergic, and toxic diseases. Toxic diseases arise from exposure to mycotoxins produced by molds. Throughout history, there have been a number of toxic epidemics associated with exposure to mycotoxins. Acute
Outbreaks of clinical disease caused by the ingestion of ergotized Lolium rigidum (annual ryegrass), which resulted in a substantial loss in production, have been reported. A number of outbreaks of a hyperthermia syndrome in cattle, characterized by severe loss in milk production, loss of body mass
Sporadic and familial hemiplegic migraines (SHM and FHM) are rare paroxysmal disorders characterized by motor aura and headache. The distinction is based on whether other family members are affected. The majority of FHM families have a mutation in one of the ion channels CACNA1A, ATP1A2 and SCN1A.
Although several studies have reported on valve abnormalities among users of fenfluramine or dexfenfluramine, detailed information on these subjects has not been provided, limiting the ability to understand who may be at risk for valve abnormalities and to generate hypotheses about the etiology and
1. The effect on rectal temperature of adrenoceptor blocking agents, injected through a cannula chronically implanted into a lateral cerebral ventricle, was examined in unanaesthetized rabbits, cats and rats, kept at room temperature (19-22 degrees C).2. In rabbits, the alpha-adrenoceptor blocking
