Early pregnancy uninterrupted by laparoscopic bipolar coagulation of uterine vessels.

Laparoscopic bipolar coagulation of uterine vessels (LBCUV) is reported to treat clinically symptomatic myomas that caused severe menorrhagia, but the viability of pregnancy after operation is unknown. A woman with clinically diagnosed uterine myomas, possibly with adenomyosis, had unexpected early pregnancy diagnosed at the time of LBCUV. The procedure resulted in improvement of menorrhagia to normal menstruation and reductions in the volume of both uterus and myomas. The intrauterine pregnancy was terminated at the woman's request. Pregnancy may be possible after LBCUV, although none has been reported.

Rapid enlargement of uterine myomas after laparoscopic bipolar coagulation of uterine vessels.

Degenerative changes occur relatively frequently in uterine leiomyomas. Morphologic changes such as necrosis, hyalinization, and alterations in cellularity are described after uterine artery embolization. A modified method to interrupt the uterine blood supply is laparoscopic bipolar coagulation of uterine vessels (LBCUV). Although the success rate is good, occasional patients require hysterectomy because of complications or continuing symptoms. A woman with symptomatic myomas underwent LBCUV, but required hysterectomy due to rapid enlargement of myomas and intractable symptoms including pelvic pain and pressure, and acute urinary retention. The combination of degenerative and iatrogenic changes resulted in a histologic appearance resembling diffuse hyalinization and hydropic degeneration of the leiomyomas.

Laparoscopic bipolar coagulation of uterine vessels to manage delayed postpartum hemorrhage.

Postpartum hemorrhage (PPH) is a big challenge for obstetricians. Fertility-preserving procedures are encouraged, especially in young women. Bilateral hypogastric (internal iliac) artery ligation, bilateral uterine artery ligation after vaginal delivery or after cesarean delivery, and uterine artery embolization are well documented vascular occlusive methods for treating PPH. To our knowledge, the laparoscopic approach to uterine artery ligation has not been reported. A 29-year-old woman experienced delayed PPH. Although curettage of the uterine cavity to remove retained placenta was performed, bleeding did not stop. We successfully performed a relatively new method--laparoscopic bipolar coagulation of uterine vessels--to stop bleeding and preserve the uterus.

Robust estimators for expression analysis.

MOTIVATION: We consider the problem of estimating values associated with gene expression from oligonucleotide arrays. Such estimates should linearly track concentration, yield non-negative results, have statistical guarantees of robustness against outliers, and allow estimates of significance and variance. RESULTS: A hierarchy of simple models is used to design robust estimators meeting these goals for both stand alone and comparative experiments. This algorithm has been validated against an extensive panel of known spike experiments, and shows comparable performance to existing standards.
