Atrial fibrillation (AF) is the most frequently observed arrhythmia in milking cows. About 50% of AF-affected cows have a history of ketosis, suggesting a relationship between AF and ketosis. Clinical signs of AF include a sudden decrease in milk production and an unstable appetite. Oral administration of quinidine is effective in the treatment of AF. AF in the pig has been observed only in one breeding animal. The clinical signs included anorexia and abnormal heart sounds. The AF was successfully terminated by the administration of 10 mg/kg quinidine every 8 h. AF in dogs and cats appears as a sign of cardiac failure, although AF may also be observed in large dogs without any underlying cardiac disease. Direct current defibrillation is effective in the treatment of these animals.

Two adolescent patients referred for evaluation of severe "hepatitis" were found to have clinically unsuspected cardiac failure. Clinical profiles were characterized by anorexia, malaise, right upper quadrant pain, mild jaundice, initially predominantly indirect hyperbilirubinemia, profound elevations of transaminases, and prolonged prothrombin time. Left ventricular failure and low cardiac output were documented by clinical examination, echocardiography, and measurements of pulmonary capillary wedge pressure and cardiac index. Acute and chronic intrinsic liver disease was ruled out by appropriate tests. At autopsy, pathologic lesions of centrilobular necrosis characteristic of hepatic hypoxia were noted, and there was evidence of marked myocardial degeneration. These two cases emphasize the need for careful cardiac examination when evaluating acute hepatitis.

An autopsy case of primary systemic amyloidosis with severe cardiac amyloidosis in a 75-year-old Japanese man is reported. The initial signs were dyspnea and cough, followed by general fatigue and loss of appetite. Heart failure, pleural effusion, and liver cysts were found on physiological examination. Autopsy findings were primary systemic amyloidosis with severe diffuse cardiac amyloidosis and cardiac hypertrophy (585 g). Focal necrosis by infarction was found in the liver and spleen. The cause of amyloidosis was unknown.

Excessive numbers of moderator bands bridging the left ventricular septum and free wall and entangling papillary muscles were associated with heart failure and death in 21 cats. Clinical findings included dyspnea, anorexia, hypothermia, cardiomegaly, pleural effusion, plumonary edema, heart murmurs, gallop rhythm, electrocardiographic abnormalities (especially conduction disturbances), increased left ventricular end-diastolic pressure, angiocardiographic evidence of left ventricular restriction, and aortic thromboembolism. Pathologic changes included a morphologically distinct network of abnormal numbers of moderator bands in the left ventricle, left ventricular hypertrophy (younger cats--mean age, 4 years) or dilatation (older cats--mean age, 8.7 years), left atrial enlargement and hypertrophy, and pulmonary edema with heart failure cells in the alveoli. Heart weights of affected cats were significantly less than those of cats with congestive, hypertrophic, and restrictive cardiomyopathy (endocardial fibrosis), but were not significantly less than heart weights of clinically normal cats. Pathologic changes were characteristic of the syndrome grossly and histologically, but clinical findings were not clearly definable.

To evaluate the potential benefit of MDL 17043, a new inotrope-vasodilator agent, in the short- and long-term management of severe heart failure, its hemodynamic effects were determined after both intravenous (cumulative average dose 3.7 mg/kg) and oral (average 18.4 mg/kg) administration in 38 patients with severe intractable heart failure. After both intravenous and oral therapy, cardiac index increased from a control value of 2.1 +/- 0.4 to 3.6 +/- 0.9 liters/min per m2, p less than 0.001 (intravenous) and from 2.2 +/- 0.5 to 3.4 +/- 0.6 liters/min per m2, p less than 0.001 (oral). Pulmonary capillary wedge pressure decreased from 26 +/- 6 to 14 +/- 7 mm Hg (p less than 0.001) and from 26 +/- 7 to 18 +/- 8 mm Hg (p less than 0.001) after intravenous and oral routes, respectively. Stroke volume index and stroke work index increased, and right atrial and pulmonary arterial pressures and systemic vascular resistance decreased by similar magnitude after both intravenous and oral MDL 17043 (all p less than 0.001). The hemodynamic effects persisted during 4 hours of observation. Thirty-seven patients were discharged while receiving MDL 17043 therapy and were followed up for a mean of 5.6 months (range 0.5 to 13). Thirty-three of the 37 patients had short-term improvement clinically by at least one New York Heart Association functional class. Undesirable effects, including nausea (35%), anorexia (27%), fluid retention (24%) and thrombocytopenia (less than 1%), necessitated discontinuation of therapy in 11 patients (30%) who were receiving multiple drug therapy.(ABSTRACT TRUNCATED AT 250 WORDS)

Sulmazol (AR-L 115 BS) is a new positively inotropic drug with arterial and venous vasodilating properties. We studied the effects of sulmazol (three-day infusion) on clinical tolerance, hemodynamics, and blood gas levels in ten patients with severe chronic heart failure. The hemodynamic monitoring included a Swan-Ganz catheter in the pulmonary artery and a radial catheter. Blood gas levels were determined on samples of arterial and mixed venous blood. After 24 hours of infusion, there was a significant increase in cardiac index (2 to 2.5 L/min/sq m; p less than 0.005) and a significant decrease in pulmonary wedge pressure (28 to 19 mm Hg; p less than 0.001) and in right atrial pressure (7 to 4 mm Hg; p less than 0.001) without significant changes in heart rate and systolic blood pressure. These beneficial effects lasted during the three days of infusion. Oxygen delivery was significantly increased (350 to 443 ml/min/sq m; p less than 0.005) without significant change in arterial oxygen tension. The side effects included nausea, vomiting, anorexia, and mild thrombocytopenia. We conclude that sulmazol is a potent drug which may improve severely deteriorated left and right ventricular function in patients with chronic refractory heart failure without affecting the heart rate and the systolic blood pressure.

A 9-year-old boy presented with increasing fatigue, anorexia, weight loss, fever, and absolute eosinophilia (48,000/microL). Pulmonary infiltrates occurred 3 months later. A murmur of mitral regurgitation was heard 5 months after onset of illness, and heart failure soon followed. Despite corticosteroid therapy the eosinophilia persisted intermittently until 1 month before death. The patient died within 9 months of the onset of illness. At necropsy there was cardiomegaly with subendocardial fibrosis in the right and left ventricles. Thrombi were present in the left ventricular apex and behind the posterior mitral leaflet. The findings in 12 previously reported pediatric cases are reviewed. The etiopathogenesis of the hypereosinophilic syndrome is discussed: half of the cases in children are associated with leukemia.

In guinea-pigs, the oral and subcutaneous LD50 values were very similar (cf. 0,173 mg/kg over 48 h with 0,116 mg/kg over 24 and 48 h). When dosed subcutaneously, a cumulative effect was observed. Intravenous administration of cotyledoside to anaesthetized guinea-pigs resulted in: dyspnoea, increased heart rates and blood pressures, and electrocardiagraphic changes typical of cardiac glycoside poisoning. A positive cardiac inotropic effect was succeeded by a positive chronotropic one. In sheep, acute and subacute intoxication resulted in ruminal, respiratory and cardiac changes. The signs included ruminal stasis, cyanosis, cardiac arrhythmia, ectopic foci and AV dissociation, followed by hypotension and progressive respiratory and cardiac failure. The skeletal muscles were affected in only 1 sheep vide infra. In chronically intoxicated sheep typical clinical signs of "krimpsiekte" developed, e.g. weakness, reluctance to stand, unsteadiness on feet, tremor and paresis of hindquarter muscles, paresis of the neck, arching of the back and standing with the feet close together. Respiratory function was affected in all 3 cases; ruminal stasis, with concomitant loss of appetite occurring in one, and a transient change in heart function in another. The syndrome induced by acute cotyledoside poisoning is similar to that of other cardiac glycosides, but the paretic signs of chronic intoxication resemble "krimpsiekte", a disease associated only with intoxication with the plants of the family Crassulaceae.

Since its discovery in 1982, neuropeptide Y (NPY) has been shown to have numerous effects mediated by a growing number of NPY receptors in both the CNS and peripheral nervous system. Perhaps best appreciated is the role of NPY in the control of systemic blood pressure, together with its effects on feeding, anxiety and memory. However, recent evidence increasingly supports an important role for NPY in mediating analgesia and hyperalgesia by distinct central and peripheral mechanisms. In this review we concentrate on this important aspect of NPY pharmacology and consider mechanisms controlling the expression of NPY and its receptors. In addition, we also present the more recent data describing the other possible roles for NPY-NPY agonists and antagonists may be useful in the treatment of conditions as varied as anorexia, epilepsy, anxiety, depression, hypertension and heart failure.

A phase II study of chemoradiotherapy for advanced squamous cell carcinoma of the thoracic esophagus was carried out cooperatively by nine Japanese institutions. Forty-five patients with thoracic advanced squamous cell carcinoma, who had T4 tumor or distant lymph node metastasis (M1(LYM)), were enrolled in the study for treatment with cisplatin (70 mg/m2) on days 1 and 36, and 5-fluorouracil infusion (700 mg/m2) on days 1-4 and 36-39 sandwiched around external beam irradiation (60 Gy over 6 weeks). Of the 45 evaluable patients, 37 (84.1%) completed the treatment. The overall response rate was 64.4%, and the complete response rate 8.9%. The median duration of response was 125.0 days for patients who achieved complete and partial response. The 50% median survival time was 215 days. There was one toxicity-related death due to radiation pneumonitis. The major form of toxicity exceeding grade 2 was myelosuppression and anorexia, but grade 4 toxicity was also observed (2 pulmonary, 1 severe hypoxemia, 1 severe cardiac failure and 1 mental disturbance). The results showed that this form of chemoradiotherapy had a satisfactory effect and might be useful for treatment of inoperable advanced esophageal cancer.
