Should the presence of coiled blood flow in the left heart ventricle and aorta be taken into consideration when constructing artificial heart valves?]

This study presented the outcome of 92 EOC patients treated by platinum or platinum analogue with cyclophosphamide from January 1, 1993 to December 31, 1995. There were 77 evaluable patients. The follow-up ranged from 4-42 months (median 14 months). The over all 3-year survival was 64 per cent and the median progression-free interval was 16 months for the whole group. There was no significant difference in survival between patients who received cisplatin and those who received carboplatin (P = 0.093). Patients who underwent optimal debulking surgery had significantly longer progression-free interval (P = 0.001) than those who had sub-optimal surgery. Fifty four per cent of patients with clear cell carcinoma died of the disease. Patients who received cisplatin had a drop out rate while on therapy more often (24% vs 5.3%) than that of carboplatin. Toxicities from chemotherapy were moderate but manageable.     

The role of the Cell Saver autologous transfusion method in preventing the pulmonary distress syndrome during open-heart operations on children

Complex estimation of the state of the lungs at the postperfusion and early postoperative periods based on roentgenological, clinical data, investigations of the parameters of oxygenation and mechanics of respiration was carried out in 32 children with septal defects of the heart, operated upon under conditions of artificial blood circulation with different kinds of the transfusion maintenance including the apparatus "Cell Saver 5" (CS) for the reinfusion of autoerythrocytes. The dynamics of endotoxicosis, hematological parameters during and after operation and requirements in transfusion media were studied. Differences in these indicators were established between the patients operated upon with the use of donor hemocomponents and those who were operated upon with CS. It allowed a conclusion about the role of the method of intraoperative reinfusion of erythrocytes in substantially less frequency and severity of the postperfusional pulmonary complications in this category of patients.
