Perihepatic adhesions: not necessarily pathognomonic of pelvic infection.

Perihepatic adhesions are often considered to be associated with pelvic inflammatory disease and subsequent infertility. Seventeen patients out of 100 undergoing elective laparoscopic sterilization had evidence of perihepatic adhesions. Four of the 17 showed evidence of old pelvic inflammatory disease, but only two gave a history of sexually transmitted disease. All patients had a negative gonorrhea culture and 50 also had a negative chlamydia culture before the procedure. These data suggest that perihepatic adhesions may be observed in otherwise normal fertile women, and its presence does not necessarily imply pelvic inflammatory disease or poor fertility.

Operative laparoscopy in the management of tubal ectopic pregnancy.

One hundred and seventeen consecutive patients with diagnosis of ectopic pregnancy admitted to Temple University Hospital between October 1989 and March 1992 were divided into two groups. Group 1 consisted of 56 patients with operative laparoscopy and Group 2 consisted of 61 patients treated by laparotomy. The two groups were similar for age, race, parity, gestation, presentation, and location of the ectopic gestations. Fifty seven percent of patients in the laparoscopy group were treated by salpingectomy and 43% by salpingostomy, compared to 84% and 16% respectively in the laparotomy group. Mean operative time for laparoscopy was 58 min and 42 min for laparotomy. Complication rates were similar in the two sub-groups. Only two patients in the laparoscopy group required subsequent laparotomy, one to assure hemostasis and one, 5 weeks following surgery, for persistent trophoblastic disease. Operative laparoscopy was associated with a significantly shorter length of hospital stay (1.25 v. 4.39 days). This reflected in a lower cost of hospital stay ($10,105 vs. $13,608). The present data demonstrates that operative laparoscopy is not only safe and effective, but also more economical than open laparotomy in the treatment of ectopic pregnancies. This procedure is expected to replace laparotomy for the treatment of most cases of tubal ectopic pregnancy.

Inhibition of spindle elongation by taxol.

During anaphase B spindle elongation, interzonal microtubules lengthen to accomplish pole-pole separation, while at the same time remaining highly dynamic [Shelden and Wadsworth, J. Cell Sci. 97:273-281, 1990]. To further examine the role of microtubule polymerization and dynamics during spindle elongation, cells have been treated with taxol, which induces microtubule polymerization and stabilizes microtubules. Taxol was added to PtK1 cells 3 minutes after initial chromatid separation, so that the effect on anaphase B could be observed with minimal disruption to anaphase A movement. In 20 microM taxol, the rate and extent of pole-pole separation, measured from time-lapse video records, are reduced to 4% and 9.5% of controls, respectively. The organization of microtubules in taxol treated cells was examined using tubulin immunofluorescence and confocal fluorescence microscopy. Taxol induces a dramatic reorganization of interzonal microtubules resulting in a narrow gap, which is nearly completely lacking in MTs, across the center of the interzone. Furthermore, microtubules in taxol treated cells are resistant to nocodazole induced microtubule disassembly. Our results reveal that taxol rapidly inhibits anaphase B spindle elongation; inhibition is accompanied by a depletion of interdigitated interzonal microtubules and a reduction in microtubule dynamic behavior.

Mesonephric rest hyperplasia. A potential diagnostic pitfall.

A case of mesonephric rest hyperplasia, an incidental finding in the hysterectomy specimen of a 48-year-old woman, was initially misdiagnosed as a well-differentiated cervical adenocarcinoma. We highlight the histologic, histochemical, and immunohistochemical features of this potential diagnostic pitfall and review the relevant literature.
