[EX Q]: Abstract: The effect of thrombolysis in acute myocardial infarction on enzymatic infarct size, left ventricular function, and early mortality was studied in subsets of patients in a randomized trial. Early thrombolytic therapy with intracoronary streptokinase (152 patients) or with intracoronary streptokinase preceded by intravenous streptokinase (117 patients) was compared with conventional treatment (264 patients). All 533 patients were admitted to the coronary care unit within 4 hr after onset of symptoms indicative of acute myocardial infarction. Four hundred eighty-eight patients were eligible for this detailed analysis, and 245 of these were allocated to thrombolytic therapy and 243 to conventional treatment. Early angiographic examinations were performed in 212 patients allocated to thrombolytic therapy. Patency of the infarct-related artery was achieved in 181 patients (85%). Enzymatic infarct size, as measured from cumulative alpha-hydroxybutyrate dehydrogenase release, was smaller in patients allocated to thrombolytic therapy (median 760 vs 1170 U/liter in control patients, p = .0001). Left ventricular ejection fraction measured by radionuclide angiography before discharge from the hospital was higher after thrombolytic therapy (median 50% vs 43% in control patients, p = .0001). Three month mortality was lower in patients allocated to thrombolytic therapy (6% vs 14% in the control group, p = .006). With the use of multivariate regression analysis, infarct size limitation, improvement in left ventricular ejection fraction, and three month mortality were predicted by sum of the ST segment elevation, time from onset of symptoms to admission, and Killip class at admission. Thrombolysis was most effective in patients admitted within 2 hr after onset of symptoms and in patients with a sum of ST segment elevation of 1.2 mV or more. On the other hand, no beneficial effects of streptokinase on enzymatic infarct size, left ventricular function, or mortality were observed in the subset of patients with a sum of ST segment elevation of less than 1.2 mV who were admitted between 2 and 4 hr after onset of symptoms.

[EX Q]: Abstract: In a retrospective study I assessed operative mortality in patients with biopsy-proven chronic hepatitis. Most patients had no symptoms from their liver disease. All patients were considered to have a viral cause of their chronic hepatitis--five were hepatitis-B surface antigen positive. Seven patients had chronic persistent hepatitis, and 13 had chronic active hepatitis (including four with cirrhosis). Twenty patients underwent 34 operative procedures, including 28 general endotracheal anesthesia and six spinal anesthesia. Although two patients who had preoperative bilirubin levels of 2.5 mg/dl or greater sustained further increases in serum bilirubin postoperatively, the serum liver chemistries of the entire group did not significantly worsen postoperatively. There was no anesthesia-related liver failure or operative mortality. Patients with asymptomatic chronic hepatitis tolerate surgical procedures well.

[EX Q]: Abstract: We describe a patient with hypertrophic osteoarthropathy secondary to regional enteritis, and review the literature on their association. The apparent different distribution of hypertrophic osteoarthropathy secondary to other causes may be artifactual and related to inadequate radiological investigation. Hypertrophic osteoarthropathy does not appear to be related to regional enteritis activity.
