Five horses with histories of colic developed signs of myocardial failure and skeletal muscle disease. Necropsy revealed pale areas in the cervical, pectoral, pelvic, and cardiac musculature; histologically, the lesions were indicative of dystrophic myodegeneration. Serum vitamin E concentrations were normal in 2 of the horses but serum selenium concentrations were normal in 2 of the horses, but serum selenium concentrations were low when compared with values obtained from clinically normal horses.

Endocarditis due to the streptococcus Bovis is an affection which is more and more often recognized and whose link with the colic tumor pathology has been well established those last few years and confirmed in this study with a frequency of 60 p. cent. However, few studies have stated the gravity of the heart affection in streptococcus Bovis septicaemias. In this series of 10 streptococcus Bovis septicaemias, the valvular affection is frequent and serious. The vegetations are found in 9 cases out of 10. The aortic affection is slightly more frequent (8 times out of 10), against 7 times out of 10 for the mitral affection (double mitroaortic affection, 6 times). A valve replacement due to sub-acute or chronic cardiac failure was necessary in 6 cases out of 9, that is 66 p. cent. The mortality was nil.

Experimental and clinical experience with compounds containing antimony have shown that the trivalent compounds are generally more toxic than the pentavalent ones. APT can cause severe pain and tissue necrosis and is therefore not given by intramuscular or subcutaneous injection. APT has the actions and uses of AST, but it is less soluble and more irritating than the sodium salt which is therefore more suitable for intravenous use. Trivalent antimony compounds are toxic when used topically. Adverse effects are similar for all trivalent compounds, and include nausea, vomiting, weakness and myalgia, abdominal colic, diarrhoea, and skin rashes, including pustular eruptions. Hypersensitivity reactions also occur. Respiratory symptoms include cough, dyspnoea, and chronic lung changes. Cardiotoxicity is the most important and may produce arrhythmias, myocardial depression and damage, Stokes-Adams attacks, heart failure, and cardiac arrest. Hepatic damage and necrosis, as well as blood dyscrasias, may occur. Toxic effects on the kidney may follow chronic use. Continuous treatment with small doses of antimony may give rise to symptoms of subacute poisoning, similar to those of chronic arsenic poisoning, due to accumulation of antimony in the body, especially if trivalent compounds are used, because of their long biological half-lives. Reproductive disorders and chromosome damage have been reported; antimony compounds are, therefore, potentially toxic to reproduction and have mutagenic, and oncogenic potential. Antimony compounds should, therefore, not be used during pregnancy or in the presence of hepatic, renal, or heart disease. Pentavalent antimony preparations especially the organic compounds, together with non-metallic synthetic preparations, such as the diamidines, have now replaced APT for use in leishmaniasis. Because of the toxicity of antimony compounds, investigations have been undertaken to reduce their adverse effects by combining them with chelating agents. These preparations appear to have reduced the toxic effects of antimony without affecting the efficacy of the preparations. Liposome-encapsulated antimony products have, more recently, been shown to be much less toxic because of the reduced dose of the antimony compound required for effective therapy. The historical uses of antimony were based on the belief that the topical and systemic adverse effects, for example, skin eruptions and diarrhoea and vomiting, were signs that the condition being treated was responding by being brought to the surface to relieve congestion at the diseased area. There is no evidence in topical use, but there is evidence that such use can cause severe reactions.(ABSTRACT TRUNCATED AT 400 WORDS)

Glucagon is an important therapeutic agent in critical care medicine. Although its endogenous hormonal functions have been well described, its clinical uses are rarely discussed. Glucagon is effective in the treatment of hypoglycemia, cardiogenic shock and heart failure, propranolol overdose, esophageal meat impaction, ureteral colic due to calculi, and acute diverticulitis. It may prove useful in the treatment of endotoxin and hypovolemic shock as well as toxicity due to excesses of procainamide, quinidine, or ouabain.

The aim of this study was to examine the results of a policy in the treatment of acute pancreatitis (AP): initial abstention, management in intensive care unit, surgery in cases of complication (infection and/or failure of medical treatment). The modalities of the surgical treatment were guided by CT scan findings: transperitoneal approach for diffuse lesions, posterior approach for localized lesions. From 1986 to 1994, 57 patients (32 males, 25 females, mean age 59.2 years) were referred to our department for AP. Etiology was gallstones in 29 cases, alcohol in 14 cases (Ranson < 3), moderate in 27 cases (Ranson < or = 5) and serious in 12 cases (Ranson > or = 6). According to the initial CT scan findings (56 cases), 9 patients were classified grade A, 11 grade B, 13 grade C, 8 grade D ans 15 grade E. Thirty eight patients were managed conservatively (mean Ranson stage 3.3), while 19 patients underwent surgical treatment (mean Ranson stage 4.6), in emergency for misdiagnosis (4 cases), or secondarily because of failure of medical management (15 cases). Surgery consisted in necrosectomy with active drainage in 13 cases and drainage alone in 6 cases. Associated maneuvers included: cholecystectomy in 8 cases, cholecystostomy in 2 cases, jejunostomy in 7 cases and colic resection for necrosis in 3 cases. Two patients (5%) managed conservatively died (multiple organ failure and cardiac insufficiency) while 4 patients (21%: NS) who underwent surgery died (2 multiple organ failures, 1 septic shock, 1 myocardic infarction). Mortality was correlated with the Ranson score: 42% for serious AP, 3.7% for moderate AP and nil for mild AP (p < 0.01). It was not correlated with CT scan grade, the onset or the type of operation. These results allow us to conclude that surgical treatment should be indicated only in cases of failure of conservative management, the best indication being uncontrolled sepsis. In this situation, active drainage provides good results since only one sepsis recurred among the 14 patients who underwent this procedure.

Acute disorder of mesenteric circulation (ADMC) is an emergency pathology of the abdominal organs. It occurs in 0.2% of general surgery patients. A total of 346 patients with verified (before, during operation and/or on autopsy) diagnosis of ADMC were analyzed retrospectively. There were 217 (62.7%) women and 129 (37.3%) men. The mean age of the patients was 68.4+/-3.6 years. In 50.7% of patients, ADMC was induced by thrombosis of the unpaired visceral branches of the abdominal aorta, in 29.1% -- by embolism of the superior mesenteric artery (SMA), in 7.8% -- by thrombosis of the portomesenteric bed, in 7.5% -- by non-occlusion mesenteric ischemia (NOMI), and in 4.9% by diseases of the parietal vessels of the bowel. The most prevalent risk factors of ADMC were: atherosclerosis of the aorta and its branches, previous reconstructions for occlusion-stenotic arterial lesions, episodes of arterial embolism in the anamnesis, congenital and acquired hemostatic disorders, oral contraception, thromboses of the deep veins and/or pulmonary embolism in the anamnesis, operations on the abdominal organs, different types of acute end chronic heart failure. In SMA thrombosis, occlusion most frequently affects the orifice (93.5%) and initial segment of the great vessel, In embolism it occurs before or at the level of the middle colic artery (in 57.9%). Disseminated bowel necroses are more frequently encountered in occlusions of the arterial bed (87.7% in thromboses and 83.3% emdolism) than in the venous system (8.3%).

Anomalous left coronary artery from pulmonary artery (ALCAPA) is a rare congenital cardiac malformation. It presents predominantly in infancy with features of myocardial ischaemia or cardiac failure and may be mistaken for common paediatric conditions such as colic, reflux or bronchiolitis. With early surgical correction the prognosis is good, but awareness of this condition is essential for prompt diagnosis and referral to a tertiary cardiac centre. In this report we review the five cases that presented during our 5-year study period and discuss the incidence and clinical presentation of ALCAPA among infants. Our observed incidence of 1 in 4243 live births--0.023%--is higher than previously reported. ALCAPA may be more common than previously recognised, and there should be a high index of awareness among paediatricians, paediatric trainees and general practitioners to enable early surgical intervention and improved prognosis for these children.

Tako-Tsubo cardiomyopathy (also known as apical ballooning syndrome) is a relatively new clinical entity characterized by reversible left ventricular dysfunction. Its clinical presentation and electrocardiographic findings are similar to acute myocardial infarction but without significant coronary artery disease. Cardiotoxicity is a major complication of various anticancer drugs; however, only a few cases of Tako-Tsubo cardiomyopathy associated with anticancer drugs, including 5-fluorouracil, have been reported. We describe a 48-year-old man who developed acute coronary syndrome, thought to be similar to Tako-Tsubo syndrome, after receiving a chemotherapy regimen consisting of 5-fluorouracil, oxaliplatin, and calcium folinate (FOLFOX protocol) for colic adenocarcinoma. Approximately 24 hours after receiving his first cycle of chemotherapy, the patient, who did not have a history of cardiovascular disease, developed chest pain, with abnormal electrocardiographic results and a mildly increased troponin T level. Coronary angiography did not show any significant coronary lesions. Echocardiography revealed marked left ventricular dysfunction (left ventricular ejection fraction [LVEF] 15%) with severe hypokinesia in all apical and median segments. The patient was stabilized with the introduction of an intraaortic balloon pump and pressor therapy. One month later, myocardial magnetic resonance imaging confirmed total recovery of left ventricular systolic function. Thus, the second chemotherapy cycle was administered at half the dose-intensity, along with ramipril and diltiazem. The chemotherapy regimen was well tolerated. Two weeks later, at the end of the third chemotherapy cycle, administered using the full-dose regimen, the patient experienced cardiac arrest, necessitating cardiopulmonary resuscitation. After transfer to the cardiology intensive care unit, acute heart failure recurred (LVEF 35%). Normal recovery of left ventricular function occurred a few days later. Chemotherapy was discontinued, and treatment with bisoprolol was started. Four months later, the patient remained completely asymptomatic of any cardiac manifestations. Use of the Naranjo adverse drug reaction probability scale indicated a probable relationship (score of 8) between the patient's development of acute coronary Tako-Tsubo-like syndrome and 5-fluorouracil. Clinicians should be aware of this potential adverse effect when monitoring patients receiving chemotherapy with 5-fluorouracil.
