RESUMEN
OBJECTIVES: In a randomized clinical trial of patients undergoing elective coronary artery bypass grafting, we evaluated the effect of intraoperative whole blood sequestration and autotransfusion on postoperative blood loss and the use of allogeneic blood products. METHODS: Male patients were included if it was possible to obtain at least 500 mL of autologous blood. For patients in group H (heparin autotransfusion, 50 patients; mean age 59 +/- 8 years), an average of 670 +/- 160 mL heparinized blood was drawn before bypass and reinfused after the period of the extracorporeal circulation. For patients in group C (citrate autotransfusion, 48 patients; mean age 60 +/- 10 years), 450 +/- 109 mL of citrate blood, drawn before administration of heparin, was used. Controls (N-group) consisted of 46 patients aged 62 +/- 8 years. Strict transfusion criteria were used, and blood loss and use of allogeneic blood products during the hospital stays of all patients were recorded. Mean differences with their 95% confidence intervals adjusted for potential confounders were obtained by multiple linear regression. RESULTS: The mean difference (95% confidence interval) of blood loss of group H minus N was -93 mL (-307 to 139) and for C minus N was -66 mL (-186 to 179). The mean number of allogeneic blood transfusions for group H was 0.85 +/- 1.74. Group C and group N used 0.94 +/- 1.56 and 0.84 +/- 1.24. CONCLUSION: In coronary artery bypass grafting there is no effect of heparin or citrate intraoperative whole blood sequestration with regard to blood loss or use of allogeneic blood.

In an open uncontrolled study of 3 patients with balanitis xerotica obliterans we have observed significant improvement after long-term systemic antibiotic therapy. Two of the patients noticed softening of the skin as well as disappearance of pruritus, tenderness, and inflammatory changes within 3 weeks of receiving oral and intramuscular penicillin. The third patient experienced the same degree of improvement after a regimen of dirithromycin, 500 mg/day. Stopping the antiobiotic for 1 month resulted in relapse, with improvement again on resumption.

Forty eight private medical practitioners and fifty six pharmacists were interviewed, using a prepared questionnaire in each group, in an attempt to evaluate the awareness and practice in the treatment of acute diarrhoea in children among private medical practitioners and the role of pharmacists in the dispensing of drugs for diarrhoea in children. 83% of the doctors prescribed an antibacterial agent, 56% prescribed loperamide, 19% of them prescribed diphenoxylate plus atropine while 31% prescribed an absorbent in children for the treatment of acute diarrhoea. Of fifty six pharmacists interviewed, 30 of them sold diphenoxylate on their own and 26 of them honoured a doctor's prescription of the same. 80% of pharmacists interviewed dispensed loperamide, more than 50% of them dispensed an antibacterial agent while 14% dispensed a binding agent such as pectin or kaolin for the treatment of acute diarrhoea without a valid prescription from a doctor. We recommend that the pharmaceuticals prominently display the harmful effects in children of drugs such as the antimotility drugs and immediately withdraw from the market, all pediatric preparations of the same.
