Breech presentation after cesarean section: Always a section?

Article Abstract:

The delivery of a breech pregnancy, where the feet, knees or buttocks are in position to come out first, is controversial and is often delivered by cesarean section (removal of the baby through an abdominal incision). Cesarean sections have considerable complications, however, including blood loss and maternal infections, which increase the possibility of the mother's death. A study was conducted between Jan 1977 and Dec 1987 to examine 71 women with previous cesarean section and singleton breech presentation to determine the need for repeat sections. Of the 71, 47 were offered a trial of labor. A trial of labor is a form of labor which is induced in order to determine the appropriateness of permitting delivery by normal means. Of the 47 women permitted to labor, 37 had successful vaginal deliveries. Infant outcome was not influenced by the method of delivery. Women delivered by cesarean had more infections. Selected breech pregnancies can have favorable results when delivered vaginally, an option which has less risk than repeat cesarean section.

RhD genotype determination by single sperm cell analysis

Article Abstract:

Testing for the presence of antibodies to the D antigen of the Rh factor in men may improve predictions of fetal Rh blood type. Researchers used polymerase chain reaction analysis to amplify the DNA of single sperm cells to identify RhD blood type. Correct RhD status was analyzed in single sperm cells from all 10 men participating. Men who have both RhD positive genes may produce only RhD positive children, even if their female partners are RhD negative. Men who have just one RhD positive gene may produce either RhD positive or RhD negative children. RhD positive fetuses whose blood is incompatible with their RhD negative mothers often experience anemia or death. Analyzing sperm cell DNA is accurate and less costly than other techniques.

Inhibitors that target protein kinases for the treatment of ovarian carcinoma

Article Abstract:

Four experimental drugs belonging to a class of drugs called tyrphostins can inhibit the growth of ovarian cancer cells in a laboratory. The drugs are AG1478, PP2, AGL2592, and AG490. All of the drugs affect enzymes called protein tyrosine kinases either directly or indirectly.
