    The degree of fluid absorption during hysteroscopic surgery in patients pretreated with goserelin
    (Journal Amer Assoc Gynecologic Laparoscopists, 1996) Taskin, O; Yalcinoglu, A; Kucuk, S; Burak, F; Ozekici, U; Wheeler, JM
    Study Objective. To assess the effects of pretreatment with the gonadotropin-releasing hormone analog goserelin on fluid absorption in patients undergoing hysteroscopic endometrial ablation. Design. Prospective, randomized, placebo-controlled study. Setting. A university-based clinic. Patients. Thirteen women with dysfunctional uterine bleeding who were scheduled for electrosurgical hysteroscopic ablation. interventions. Seven women were randomized to receive luteal phase goserelin 3.75 mg and six saline in the menstrual cycle approximately 10 weeks before surgery. Operative hysteroscopy was carried out with glycine 1.5% mixed with 2% alcohol medium under constant pressure as an irrigant. The amount of irrigant used, irrigant deficit, blood levels of albumin and ethanol, hematocrit, hemoglobin, changes in sodium levels, and central venous pressure were compared between the groups. Measurements and Main Results. All of the patients had an unsuccessful course of medical therapy for at least 3 months and a normal endometrial biopsy. The age, weight, and uterine size were similar between the groups. The mean volume of irrigant used and operating time were similar in both groups (4.18 +/- 0.2 vs 4.5 +/- 0.5 L, and 33.7 +/- 1.5 vs 37 +/- 2.1 min). Although operating time, volume deficit, decrease in protein level, and hematocrit were less in the goserelin than in the saline group, the differences were not statistically significant (p >0.05). The ethanol levels in blood, decrease in Na+, and irrigant deficit were significantly lower in the goserelin than in the saline group (17.4 +/- 3.8 vs 25.3 +/- 4.2 mg/ml, 6.7 +/- 1.2 vs 9.1 +/- 0.9 mEq/L, and 0.49 +/- 0.08 vs 0.66 +/- 0.05 L, respectively; p <0.05). Conclusion. Based on these results we conclude that in women undergoing hysteroscopic endometrial ablation, pretreatment with goserelin may decrease the absorption of hysteroscopic medium, prevent fluid overload, and improve the outcome possibly by causing hypovascularity and decreased endometrial growth.

    Placebo-controlled cross-over study of effects of tibolone on premenstrual symptoms and peripheral ?-endorphin concentrations in premenstrual syndrome
    (Oxford Univ Press, 1998) Taskin, O; Gökdeniz, R; Yalcinoglu, A; Buhur, A; Burak, F; Atmaca, R; Ozekici, U
    Central nervous system hormones have been linked to premenstrual syndrome (PMS) and beta-endorphin (beta-EP) is thought to be involved in the pathophysiology. We have tested the efficacy of the synthetic steroid Org OD 14 (tibolone) in the treatment of PMS, This prospective, randomized, placebo-controlled, double-blind cross-over study included 18 ovulatory women with PMS as ascertained by a visual linear analogue scale (VLAS), The women in each group received either 2.5 mg per day Org OD 14 (n = 9) or a multi-vitamin pill as placebo (n = 9) for 3 months. Treatments were then crossed over to a placebo for a further 3 months, VLAS ratings were evaluated at the end of each menstrual cycle throughout the study. Peripheral beta-EP concentrations were determined by radioimmunoassay on days 7 and 25 of each menstrual cycle. Changes in VLAS score and beta-EP concentrations from baseline were calculated and analysed by Student's paired t-test, Improvements in VLAS scores and beta-EP concentrations were evident during the second and third months of tibolone treatment. At the end of the third month, there was a significant improvement in VLAS scores of all symptom categories compared with pretreatment and placebo during treatment with tibolone (P < 0.05), Similar results were obtained in the first placebo group when switched to tibolone, beta-EP concentrations were not significantly different between the study groups at the initial cycle (15.9 +/- 3.6 versus 17.2 +/- 2.3 pg/ml), The increase in beta-EP concentration was significantly greater on day 25 of the menstrual cycle in women treated with tibolone compared with baseline and placebo group (22.5 +/- 4.4 versus 15.9 +/- 3.6 and 17.2 +/- 2.3 pg/ml respectively, P < 0.05). Our data confirm the clinical efficacy of tibolone in PMS-related symptoms, as well as its effects on serum beta-EP concentrations in patients with PMS.
