RESUMO
BACKGROUND: Since the introduction of cephalic replacement for shoulder dystocia, the management of failures has not been addressed. The purpose of this report is to describe abdominal hysterotomy as an alternative approach to the resolution of shoulder dystocia. CASE: A 21-year-old woman, gravida 1, experienced severe shoulder dystocia following partial delivery of a 4320-g infant. Classical maneuvers as well as cephalic replacement were unsuccessful before and after general anesthesia. A low transverse hysterotomy permitted manual rotation of the anterior shoulder to the oblique diameter and further descent of the posterior shoulder. Delivery of the posterior arm was then completed without difficulty. CONCLUSION: Persistent failed cephalic replacement, especially after general anesthesia, can be successfully resolved with a hysterotomy using a low transverse uterine incision.

The aim of this study was to verify the presence of androgen receptors (AR) in human colorectal adenomas and in normal adjacent mucosa, and to determine whether there is any difference in AR tissue content between females and males. Our data show higher levels of nuclear AR in normal mucosa than in adenomas (p less than 0.001). A significant difference was also present in males between normal and pathological tissue both in cytosolic (p less than 0.05) and nuclear receptors (p less than 0.01). In female subjects this difference was also evident, but not significant. Our results seem to support the hypothesis of protective effects of androgens in colonic mucosa.
