[Clinical course and prognosis of myocardial infarction].

1000 patients with myocardial infarction between 1975 and june 1991 were admitted in the cardiac unit at the university hospital in Sfax. The mean age is 60 years, with a masculine predominance (86%). The time between, onset admission is long, 47.4% were admitted within 24 h after onset and 16.5% within 6 h after onset. The site of MI was more often in anterior region (58.6%) against 36% in the posterior region. Evolution was favorable in 34.7% of cases, 36.5% cases of left cardiac failure were noted, and 11.7% of cardiogenic shock rhythm disorders were noted in 34.6% of cases (under estimated) and conduction disorders were noted in 22% of cases. Early mortality is about 17.4% occurring more often during the first 3 days.

[Indications for angiographic study of renal arteries in elderly hypertensive subjects].

During a 30 months period, 70 patients (60-84 years old) underwent a renal artery angiographic investigation, either by combined intravenous angiography and pyelography, either by intravenous or intra-arterial digital angiography. Thirty-nine were males, 31 were females. All patients were hypertensive. Thirty-three had a normal renal function and 37 had a renal insufficiency arbitrarily definite as creatinine clearance lower than 60 ml/min (m = 33 +/- 15 ml/min). Eight aortic anevrysms were discovered. Thirteen patients (18.6%) had atherosclerotic renovascular disease. Criteria which led to undertake these investigations and results are listed in the following table. [table; see text] Transluminal percutaneous angioplasty and surgical treatment were performed 7 and 3 times respectively. In one case, nephrectomy was done. In all these patients but one, improvement of hypertension and/or renal function occurred. In patients with renal impairment, difference in size between the two kidneys detected by echography or plain abdominal X-rays were noted in 8 among the 9 patients with renovascular disease; six among them had proteinuria less than 0.5 g/day. In conclusion, in hypertensive patients older than 60, criteria for detection of renovascular disease are the same as in younger patients. When renal function is decreased, difference in size between the two kidneys requires an angiographic evaluation. Proteinuria does not exclude renovascular pathology.

[Brucella endocarditis on Starr aortic valve prosthesis].

The authors report the case of a 22 year old patient with brucella endocarditis on a Starr-Edwards aortic valve prosthesis implanted 5 years previously. Six blood cultures were positive for Brucella melitensis biovar I. Antibiotic therapy associating Rifampicin and Tetracycline and then Rifampicin and Ofloxacine did not prevent abscess formation and valve dehiscence. The poor haemodynamic status and persistent infection led to replacement of the valve prosthesis. Culture of the infected prosthesis grew a colony of brucella melitensis resistant to fluoro-quinolones. Valve replacement and antibiotic therapy led to clinical improvement and constant apyrexia with a 12 month follow-up. Brucella endocarditis on a valve prosthesis is a very rare occurrence. The combination of valve replacement and antibiotic therapy is usually required.

[Comparative study of the University of Wisconsin solution versus Eurocollins in kidney transplant].

UW (University of Wisconsin) solution, formulated by Belzer's team in Madison, has already been proved to increase cold ischemia time in liver and pancreas preservation. A multicentre clinical trial is being conducted to compare renal preservation in human transplantation using two different solutions: UW and Eurocollins (EC). This paper, whose results will be included in the multicentre trial, reports local comparative results between UW and EC perfused Kidneys. The two donor populations UW (28 cases) and EC (47 cases) were not randomized. They were however comparable in renal function prior to harvesting but not in age (35 +/- 13.4 years EC versus 27.7 +/- 12.4 years UW). The two recipient populations (48 EC versus 48 UW) were more homogeneous. Comparative results were significant with better graft function in the UW group: creatinine at one week: 499.2 +/- 296.3 EC versus 277.6 +/- 226.2 mumol/l, p less than 0.0001; creatinine at one month: 228.7 +/- 135 EC versus 159.7 +/- 135.6 mumol/l, p less than 0.02 and a decrease in acute tubular necrosis (39.5% EC versus 14.5% UW) and hospital stay. These results justify the use of UW solution by intraaortic flush especially during multi-organ procurement.
