[Thrombolysis in acute myocardial infarction in the aged. A greater risk of cardiac rupture?].

OBJECTIVE: To evaluate age group and i.v. thrombolytic therapy (TT) influences on cardiac rupture complicating acute myocardial infarction (AMI). CONCEPTION: Retrospective analysis of patients (pts) admitted during 1988-89 to an Intensive Care Unit of a Terciary Hospital (UCIM) with AMI. POPULATION: 430 pts were admitted with AMI. During this period 89 pts were submitted to TT (25% age greater than or equal to 65 years). Eighty four pts died during hospital stay and 42 had autopsy study (50%). Only 7 of nonautopsied pts died of undetermined cause. Dead pts had age m +/- SD 72 +/- 11 years old (yo) (37% female, 63% male and 74% age greater than or equal to 65 yo). RESULTS: Nineteen pts died of cardiac rupture (CR) (23%). CR prevalence was 1.4% (3/218) in pts less than 65 yo and 7.5% (16/212) in pts greater than or equal to 65 yo (p less than 0.01). CR prevalence in pts submitted to TT (4.5%) 4/89, was similar to pts not submitted to TT (4.4%) 15/341 (n.s.). Pts less than 65 yo had nonsignificant differences in CR wether submitted or not to TT (0% vs 2%). Elderly pts (greater than or equal to 65 yo) CR prevalence was 18% (4/22) in those submitted to TT vs 6% (12/190) in those not submitted to TT (p less than 0.05). CONCLUSIONS: Thrombolytic therapy may carry an additional risk for cardiac rupture in elderly patients (greater than or equal to 65 yo).

Combined approach to the differential diagnosis of cholestatic jaundice with endoscopic retrograde cholangiopancreatography, percutaneous transhepatic cholangiography, ultrasonography, and liver biopsy.

A prospective study of 33 patients with cholestatic jaundice was performed with combined use of endoscopic retrograde cholangiopancreatography (ERCP), percutaneous transhepatic cholangiography (PTC), ultrasonography, and liver biopsy. A higher rate of success with PTC in 25 cases of extrahepatic cholestasis was offset by the better score of ERCP in 8 cases of intrahepatic cholestasis and its wider diagnostic scope. The procedures were complementary in 10 cases. Ultrasonic imaging of intrahepatic bile ducts proved useful for selecting the first cholangiographic technique. Liver biopsy established etiology in intrahepatic cholestasis. Our combined approach allowed us to develop through objective criteria a diagnostic flow chart of cholestasis.

[A cost-benefit evaluation of prenatal diagnosis performed at a referral center with a population with a genetic or abnormality risk].

Prenatal diagnosis (PND) has assistencial, psychological and economical consequences; it is very important to evaluate cost effectiveness for the population. A prospective study was done (longitudinal and descriptive) on a population referred to Maternidade Dr. Alfredo da Costa, divided into two groups. Group one with PND performed on proper time and second group a PND procedure performed on a adequate time. The general characterization, indications for reference and consequences were evaluated. The conclusions are that the indications for reference were correct and the diagnosis was effective in 17% of patients. Social, economical levels and multiparity were the most important factors affecting adequate PND. However concerning the results, the termination of pregnancy was more performed on the group 1 and more abnormalities were seen on the newborns of group 2.
