Action of aromatase inhibitor for treatment of uterine leiomyoma in perimenopausal patients

Objective: To assess the effect of the aromatase inhibitor on patients with leiomyoma in the reproductive stage regarding reduction of uterine volume and control of symptoms. Design: Clinical study. Setting: Academic clinical practice. Patient(s): Twenty patients, over 35 years of age, with symptomatic uterine leiomyoma. Intervention(s): Anastrozol, 1 mg/day for 12 weeks. Main Outcome Measure(s): Measurement of uterine volume, assessment of symptoms related to uterine leiomyoma, serum assay of follicle stimulating hormone (FSH), and estradiol. Results: Average reduction of uterine volume of 9.32%, attaining up to 32%, and reduction of symptoms of uterine leiomyoma (menstrual volume, duration of menstruation, and dysmenorrhea). No significant change in serum levels of FSH and estradiol during use of the medication were observed. Conclusion(S): Anastrozol proved to be effective in reducing the volume of the uterus-leiomyoma structure, leading to the control of symptoms connected with the disorder without changes in serum FSH and estradiol.

Prevalência de sintomas depressivos na perimenopausa

OBJETIVO: realizar revisão sistemática de estudos de prevalência dos sintomas depressivos na perimenopausa.MÉTODO: A pesquisa foi efetuada a partir das bases de dados MEDLINE e EMBASE. Foram incluídos estudos transversais originais com populações adultas (idade de 40 a 55 anos), no período de 1996 a 2006, que estimaram a prevalência de sintomas depressivos na perimenopausa nos idiomas: inglês, francês, espanhol e português. A seleção dos estudos pela estratégia de busca foi feita de forma independente por dois avaliadores. Foram incluídos os estudos que preencheram os seguintes critérios metodológicos: características epidemiológicas, definições de perimenopausa, instrumentos válidos utilizados para sintomas depressivos.RESULTADOS: Após a avaliação de 1.345 artigos, restaram apenas cinco que caracterizaram uma população de 11.020 mulheres com idades entre 40 e 60 anos. Constatamos que a prevalência de sintomas depressivos na perimenopausa variou entre 19% e 73%.CONCLUSÃO: A presente revisão sistemática mostrou expressiva variação na prevalência de sintomas depressivos na perimenopausa; ademais, não foi possível caracterizar se a sintomatologia depressiva na perimenopausa decorreu exclusivamente de flutuações hormonais observadas neste estágio da vida ou de antecedentes prévios de depressão

The effects of topical isoflavones on postmenopausal skin: Double-blind and randomized clinical trial of efficacy

Objective: The aim of this study was to evaluate the effects of estrogen and isoflavones on postmenopausal skin morphological parameters. Study design: A randomized, double-blind, estrogen-controlled trial was performed on postmenopausal women treated in the Gynecology Department of the Federal University of Sao Paulo. This study was designed to analyze the effects of topical administration of estradiol and isoflavones on facial skin for 24 weeks. The participants were divided into two groups: G1-17-betaestradiol 0.01% (n = 18) and G2-isoflavones 40% (genistein 4%, n = 18). Skin biopsies were performed on each patient before and after the treatment. The skin samples were processed for histological analysis, stained with haematoxylin and eosin, and examined using light microscopy. Results: After 24 weeks of treatment, the estradiol group had a significant increase in skin parameters analyzed compared to the isoflavone group and to the baseline measurements: epidermal thickness (a 75% increase in the estrogen group and 20% in the isoflavone group), number of dermal papillae (a rise of 125% with estrogen, no significant gain with isoflavones), fibroblasts (a 123% accretion with estradiol, no significant gain with isoflavones), and vessels (a 77% increase with estrogen and 36% with isoflavones). Conclusion: Our data suggest that estrogens may have a stronger effect on histomorphometrical parameters than isoflavones. (C) 2009 Elsevier Ireland Ltd. All rights reserved.

Consumption of a Flaxseed-Rich Food Is Not More Effective Than a Placebo in Alleviating the Climacteric Symptoms of Postmenopausal Women

Our objective in this work was to test the effects of daily intake of bread produced with partially defatted ground flaxseed on the climacteric symptoms and endometrial thickness of postmenopausal women. A double-blind, placebo-controlled, randomized clinical trial was performed with 38 women who had been postmenopausal for 1-10 y and consumed 2 slices of bread containing 25 g of flaxseed (46 mg lignans) or wheat bran (<1 mg lignans; control) every day for 12 consecutive weeks. The outcome variables were the daily number of hot flashes, the Kupperman Menopausal Index (KMI), and endometrial thickness. The plasma lipid profile (total cholesterol and HDL, LDL, and VLDL cholesterol fractions and triglycerides) and the hormones estradiol, follicle-stimulating hormone, thyroid-stimulating hormone, and free thyroxine also were measured. Food intake was evaluated by means of 2 24-hrecalls, before and after the treatment. Twenty patients in the study group and 18 in the control group completed the study. The general characteristics did not differ between the 2 groups at the start of the study. Both had significant, but similar, reductions in hot flashes and KMI after 3 mo of treatment. Moreover, endometrial thickness was not affected in either group. Our findings clearly show that although flaxseed is safe, its consumption at this level (46 mg lignans/d) is no more effective than placebo for reducing hot flashes and KMI. J.
