[Blood transfusion from cadavers].

Most of the transplant programs in our days are based on cadaveric donation; blood has been not recovered from dead bodies, except by some Soviet groups. We selected 16 subjects, eight with brain death and eight with "biological" death (heart arrest) that were considered as ideal donors. From them we obtained 23 units of whole blood, either by surgical dissection of the internal jugular vein, by puncture of the femoral artery or by puncture of a peripheral arm vein. Twelve were not used due to bacterial growth, HBsAg positivity or hemolysis. Of the remaining, we obtained 10 packed red cells and 10 units of plasma, one unit was transfused as whole blood. Three plasma units were discharged due to "turbidity". Sixteen patients for whom it was difficult to get a voluntary donor were transfused with some of the products and followed for as long as they remained in hospital. None showed adverse reactions due to the procedure. We conclude that the organization of any program related to the transplantation of organs is not a simple matter, but that blood is easily recovered and that this should be done always as part of the "total use" of a donating body; cadaveric blood transfusion is harmless provided donors are carefully selected and that the sterility of the product is confirmed by culture.

Factors associated with use of the contraceptive sponge.

A study of 264 current sponge users, 266 pill users and 45 diaphragm users shows that women who adopted the sponge were older, more educated and more likely to be married, to have higher incomes and to have had more pregnancies and children than were women who had used oral contraceptives. Compared with diaphragm users, sponge users were more likely to be never-married, had had fewer children and were more likely to be Protestant. Users of all three methods cited physicians as being the greatest source of influence in the decision to adopt their current method; however, sponge users were the least likely to cite physicians, and they were more likely to have been favorably influenced by the media than were pill or diaphragm users. Sponge users were more likely than pill users to have ever relied on other contraceptive methods and to have correctly answered more questions on contraceptive knowledge. Sponge users and diaphragm users were similar in the range of methods they had ever used and in contraceptive knowledge. However, sponge users reported more consistent use than did diaphragm users.

Advantages of a 400 speed image receptor system for cast radiography.

By using a faster intensifying screen as opposed to the traditional extremity system for cast radiography, one can reduce the dose to the patient significantly while maintaining quality cast radiographs. In this study a 400 speed Lanex Regular, TMG film system was compared to a 100 speed Lanex Fine, TMG film system. The findings suggest that slow speed, high resolution systems are unnecessary for cast radiography. Evidence demonstrated reduced patient exposure and suggested decreased motion and increased tube life as a result of shorter exposures.
