Sacrocolpopexy--a report on 262 consecutive operations.

OBJECTIVES: This report analyses the outcome and complications of 262 consecutive sacrocolpopexy procedures for the repair of vaginal vault prolapse and enterocele. METHODS: From March 1994 to February 2001, 262 patients underwent surgical repair using a standardised retroperitoneal technique. Initially dura mater strips were used and from the 19th patient onwards, Gore-tex soft tissue patch was used to suspend the vaginal apex to the anterior sacral ligament. Halban-type occluding sutures were placed in the pouch of Douglas. All patients were followed up and the minimum duration of follow-up was 16 months. RESULTS: Vaginal vault prolapse was successfully managed in 259 of 262 patients giving a success rate of 98.8%. In addition, 4 patients had a repeat enterocele that required surgical repair. The overall surgical complication rate was low. Erosion of the patch through the vaginal vault occurred in 10 patients, necessitating removal of the patch. Prolapse did not recur in any of these patients. CONCLUSION: Abdominal sacrocolpopexy is a very successful and safe surgical management of vaginal vault prolapse.     

Osteoid osteoma. Diagnosis, localization, and treatment

The preoperative insertion of a needle under computed tomographic scan, performed under local anesthesia, is a convenient and important new way to localize the nidus in osteoid osteoma. It necessitates less bone removal, which should reduce the postoperative fracture rate. It should also help to locate the lesion during surgery. Some clinical points and previously unstressed pathologic findings are also discussed.     

The effect of α-amylase on the acrosomal membrane of human sperm

Purpose Sperm capacitation and the acrosome reaction are prerequisites to accomplishing fertilization. The object of this research was to induce capacitation and the acrosome reaction of human sperm, comparing the acrosome status of fertile and infertile men, using -amylase.Methods Acrosome status was measured using indirect immunofluorescence (IIF; monoclonal antibody GB24, Thèramex), hemizona assay (HZA), and transmission electron microscopy (TEM).Results Acrosome-reacted sperm without -amylase treatment was significantly more abundant in the fertile versus the infertile group utilizing IIF, HZA, and TEM. -Amylase-treated spermatozoa from the fertile and infertile groups showed a significant increase in the number of sperm bound to the hemizona (P <0.05).Conclusions The percentage of acrosome-reacted sperm in the infertile group was significantly enhanced by a-amylase, utilizing IIF and TEM.     

2-methoxyestradiol strongly inhibits human uterine sarcomatous cell growth

OBJECTIVES: The objective was to test the hypothesis that uterine sarcomatous cells are hormone-sensitive. We included 2-methoxyestradiol, an endogenous metabolite of estradiol with antiproliferative properties. METHODS: Proliferation assays assessed the effects of estradiol, progesterone, tamoxifen, raloxifen, [D-Trp(6)]leuteinizing hormone-releasing hormone (LHRH), ICI 182,780 (faslodex or fulvestrant), and 2-methoxyestradiol on cell growth of a cell line derived from uterine carcinosarcoma, but consisting solely of mesenchymal cells (SK-UT-1). Morphological changes of SK-UT-1 cells after exposure to 2-methoxyestradiol were evaluated and fluorescence immunohistochemistry for tubulin was used to detect changes in the mitotic spindle. Flow cytometry was used to assess the influence of 2-methoxyestradiol on the SK-UT-1 cell cycle as well as the role of p53 in apoptosis. RESULTS: Cell proliferation analysis revealed that SK-UT-1 cells were stimulated by progesterone, tamoxifen, and [D-Trp(6)]LHRH. Cells were insensitive to estradiol, raloxifen, and ICI 182,780. Inhibition occurred after exposure to 2-methoxyestradiol and was accompanied by a threefold increase in the G2/M population, with a concomitant decrease in the G1 population, as shown by cell cycle analysis. SK-UT-1 cells exposed to 2-methoxyestradiol showed morphological changes indicative of apoptosis. Examination of signaling pathways that mediate 2-methoxyestradiol-induced apoptosis showed p53-independent growth inhibition. The inhibition of SK-UT-1 cell growth by arresting the cells during G2/M progression could be attributed to interference with the microtubule system, as determined by fluorescence immunohistochemistry. CONCLUSIONS: The stimulatory effect of progesterone, tamoxifen, and [D-Trp(6)]LHRH suggests that uterine sarcomatous cells are hormone-sensitive. Our finding that 2-methoxyestradiol-mediated growth inhibition of uterine sarcomatous cells occurred in a p53-independent manner may have considerable clinical significance. The inadequate armature against uterine sarcomas and the limited toxicity of 2-methoxyestradiol may render these observations especially important.     

Fat embolism and the fat embolism syndrome. A double-blind therapeutic study

Fifty-five adults who had sustained a tibial fracture, or a femoral fracture, or both, were subjected to a double-blind randomised study to determine the efficacy of methylprednisolone in treating the fat embolism syndrome. This drug maintained arterial oxygen levels, stabilised or reduced the serum level of free fatty acids, and decreased the risk of the fat embolism syndrome in a statistically significant proportion of patients. Gurd's criteria for the diagnosis of the fat embolism syndrome were found inadequate. Other more sensitive criteria for early diagnosis and effective management were determined. There were no deaths or serious morbidity in our series.     

A properly conducted trial of a ventouse can prevent unexpected failure of instrumental delivery

A retrospective study over a 5-year period reviewed 71 unexpected failures of instrumental delivery and compared them with a group of 21 trials of ventouse to identify causes for failure and their impact on neonatal outcome. There was a statistically significant difference between the two groups in terms of pre-application assessment of fetal size, maternal pelvis and palpable fetal head above the pelvic brim (P less than 0.00001). There was also a significant difference in neonatal morbidity (P less than 0.01). All 5 neonatal deaths occurred in the failure group and were associated with multiple instrumentation.
