Comparison of the effects of tibolone and estrogen therapy on hemostasis in surgical menopause: a randomized, double-blind, placebo-controlled study.

OBJECTIVE: To examine the effects of unopposed estrogen (E) and tibolone therapy on coagulation and natural anticoagulant systems in surgical menopause. DESIGN: A randomized, double-blind, placebo-controlled study. SETTING: University hospital clinic in Turkey. PATIENT(S): Ninety healthy surgically postmenopausal women. INTERVENTION(S): Ninety surgically postmenopausal women were randomized into three groups: unopposed conjugated ET (0.625 mg/d, group 1), tibolone (2.5 mg/d, group 2), and identical tablets of placebo (group 3). MAIN OUTCOME MEASURE(S): Effects on parameters in the clotting cascade at baseline and after 24 weeks of treatment. RESULT(S): After 6 months, fibrinogen, lipoprotein (a), and factor VIIa were decreased, and activated partial thromboplastin time was increased significantly in the ET group compared with in the placebo group. However, tibolone significantly decreased only the serum levels of factor VIIa and factor IX and prolonged the activated partial thromboplastin time, compared with placebo group. In addition, conjugated ET caused a significantly greater decrease in serum fibrinogen level than did tibolone. CONCLUSION(S): Neither E nor tibolone therapy led to activation of coagulation in the surgically menopausal women. Both preparations changed the overall hemostatic balance to a more fibrinolytic state.

Recurrence and prognostic factors in borderline ovarian tumors.

OBJECTIVE: The purpose of this study was to evaluate the survival estimates and clinico-pathological variables in patients treated for borderline ovarian tumors. METHODS: The patients treated for borderline ovarian tumors were evaluated retrospectively. Data were obtained from hospital records and special gynecologic oncology forms. RESULTS: Overall, 100 patients were evaluated. The mean age at the time of diagnosis was 41.7 (range, 19-84). Seventy one (71%) patients underwent surgical staging including 49 (49%) of them with comprehensive surgical staging, 22 (22%) with fertility-sparing surgery. Only 30 (30%) patients were unstaged. The histopathological diagnosis was serous, mucinous, and the other types of borderline ovarian tumor in 54 (54%), 39 (39%), and 7 (7%) of the patients, respectively. Seventy patients had stage IA (70%), 10 had stage IB (10%), 9 had stage IC (9%), 3 had stage IIIA (3%), and 8 had stage IIIC (8%) disease. The stage of only four patients in which disease confined to ovary was upgraded as stage IIIC following surgical staging procedure. The recurrence rate was found 3% (3). The overall disease-free survival rates of BOT in surgically staged (comprehensive, fertility-sparing surgery) and unstaged patients were 97.92%, 95.00%, and 96.30%, respectively. But, the overall tumor-free survival was significantly found to be decreased in cases of young age (<30 years old), performing fertility-sparing surgery and presence of micropapillary architecture or peritoneal implants. Overall survival rates of BOT in surgically staged (comprehensive, fertility-sparing surgery) and unstaged patients were 97.9%, and 100% and 100%, respectively. CONCLUSION: Low malignant potential ovarian tumors have excellent survival, and the patients can be treated safely by conservative surgery.

Two successful spontaneous pregnancies in a patient with a primary primitive neuroectodermal tumor of the ovary.

OBJECTIVE: To describe a patient with primary primitive neuroectodermal tumor of the ovary with two successful spontaneous pregnancies. DESIGN: Case report. SETTING: Tertiary center for gynecologic oncology. PATIENT(S): A 25-year-old woman with two spontaneous pregnancies 5 months after and 2 years after conservative treatment of International Federation of Gynecology and Obstetrics stage IC primary primitive neuroectodermal tumor of the ovary. INTERVENTION(S): Assessment of extraovarian spread with staging laparotomy. Four courses of BEP (bleomysin, etoposide, cisplatin) and, for recurrent disease, six courses of salvage VIP (vinblastin, iphosphamide, mesna, cisplatin) chemotherapy. MAIN OUTCOME MEASURE(S): Two successful deliveries and no residual ovarian cancer. RESULTS(S): A healthy, normal female infant weighing 3600 g was delivered by cesarean section at 38 weeks' gestation. Sixteen months later another infant, a healthy, normal male weighing 3500 g, was delivered by cesarean section at 38 weeks' gestation. No residual cancer was detected at follow-up 12 months after the last delivery. CONCLUSION(S): Conservative fertility-preserving treatment might be considered in patients with primary primitive neuroectodermal tumor of the ovary. Without any assisted reproductive technologies, spontaneous pregnancies might occur.

Vulvar edema as a rare complication of laparoscopy.

Vulvar edema as a complication of laparoscopy is a rare condition. A 23-year-old woman was admitted with progressive dysmenorrhea and underwent laparoscopic bilateral endometrioma cystectomy. Twenty-seven hours after surgery, unilateral vulvar edema was observed. It resolved with the application of ice packs and insertion of a Foley catheter. We conclude that this is a rare, normally benign condition that is easy to manage.
