Acupuncture ameliorated vasomotor symptoms during menopausal transition: single-blind, placebo-controlled, randomized trial to test treatment efficacy.

OBJECTIVES: This study aimed to evaluate the effects of acupuncture on women with vasomotor symptoms during the menopausal transition with the aid of the Kupperman-Blatt Menopausal Index. METHOD: Crossover, single-blind, sham-controlled trial with 100 women randomly divided into two groups of 50 participants each: G1 and G2. During the first 24 weeks of treatment, the G1 women received acupuncture and the G2 women were given sham acupuncture. The crossover was then applied: the G1 participants were given sham acupuncture, and the G2 participants received acupuncture for 24 more weeks. RESULTS: The mean score of hot flashes of the group who first experienced acupuncture (G1) was statistically higher than that of the group that started with sham acupuncture (G2, P = 0.020). Also, both groups had similar mean scores in the middle of the study (both were receiving acupuncture). During the last 6 months of the study, after crossover, the values of G2 (acupuncture) were lower than those of G1 (sham acupuncture). CONCLUSIONS: Acupuncture treatment may mitigate hot flashes and other climacteric symptoms during the menopausal transition.

The clinical, structural, and biological features of neovaginas: a comparison of the Frank and the McIndoe techniques.

OBJECTIVE: To compare two methods of neovagina construction, the Frank and McIndoe techniques, in terms of structural and biological aspects. STUDY DESIGN: A total of 55 subjects were included in this retrospective study: 43 underwent the Frank technique (FT) and 12 underwent the McIndoe technique (MT). A clinical evaluation and a comparison of the structural (color, shine, presence of hair, and histology) and biological (bacteriological, pH, and hormonal determinations) features were performed. Statistical analysis was performed using the Fisher and Mann-Whitney tests. RESULTS: The time to achieve a functional neovagina using the FT was longer than when using the MT (9.8±5.3 versus 5.8±2.9 months) (p=0.01). The neovaginal wall of the MT skin grafts was more rigid and drier, and it did not exhibit a shine in the way that the FT skin grafts did. The lining of the cavity formed by the FT in all subjects was similar to that of vaginal mucosa, whereas the lining formed by the MT persisted as a skin graft in 83.3% of the cases. The pH was lower for the FT (p<0.01), and Döderlein bacilli were present in 90% of the FT neovaginas but absent from the MT neovaginas. In the latter, flora with anaerobic bacteria was present. Hormonal cytology showed estrogen activity in 100% of the FT neovaginas, but there was no such activity in the MT neovaginas. CONCLUSIONS: Our data suggest that the FT may be clinically, structurally, and biologically superior to the MT for the creation of neovaginas and is also less costly.

Effects of estrogen therapy and aerobic training on sympathetic activity and hemodynamics in healthy postmenopausal women: a double-blind randomized trial.

OBJECTIVE: The aim of this study was to evaluate the isolated and associated effects of aerobic training and estrogen therapy on sympathetic nerve activity and hemodynamics in healthy postmenopausal women. METHODS: Forty-five postmenopausal women (mean [SD] age, 51 [3] y) were randomly divided into four groups: sedentary-placebo (SED-PLA; n = 11), sedentary-estrogen therapy (SED-ET; n = 14), aerobic training-placebo (AT-PLA; n = 12), and aerobic training-estrogen therapy (AT-ET; n = 8). The ET groups received oral estradiol valerate (1 mg/d), whereas the PLA groups received placebo. The AT groups performed aerobic exercise three times a week on a cycle ergometer for 50 minutes, whereas the SED groups remained sedentary. All participants were evaluated before and after 6 months. Muscle sympathetic nerve activity (MSNA; microneurography), forearm blood flow (plethysmography), blood pressure (oscillometry), and heart rate (HR) were measured at rest for 10 minutes. Data were analyzed by three-way analysis of variance. RESULTS: Estrogen administration itself did not change any of the studied parameters. AT improved forearm blood flow (AT-PLA, 2.02 [0.85] vs 2.92 [1.65] mL min(-1) 100 mL(-1), P = 0.03; AT-ET, 1.68 [1.11] vs 2.27 [0.76] mL min(-1) 100 mL(-1), P = 0.03), reduced MSNA in the AT-PLA group (39 [6] vs 34 [5] bursts/min(-1), P = 0.01), and decreased HR in the AT-ET group (65 [8] vs 62 [7] beats/min, P = 0.01). CONCLUSIONS: AT reduces sympathetic nerve activity and improves muscle blood flow in healthy hysterectomized postmenopausal women. Moreover, AT decreases HR when combined with ET. However, ET abolishes the reducing effect of AT on MSNA.

Normal sonographic anatomy of the abdomen of coatis (Nasua nasua Linnaeus 1766).

BACKGROUND: The use of ultrasound in veterinary medicine is widespread as a diagnostic supplement in the clinical routine of small animals, but there are few reports in wild animals. The objective of this study was to describe the anatomy, topography and abdominal sonographic features of coatis. RESULTS: The urinary bladder wall measured 0.11 ± 0.03 cm. The symmetrical kidneys were in the left and right cranial quadrant of the abdomen and the cortical, medullary and renal pelvis regions were recognized and in all sections. The medullary rim sign was visualized in the left kidney of two coatis. The liver had homogeneous texture and was in the cranial abdomen under the rib cage. The gallbladder, rounded and filled with anechoic content was visualized in all coatis, to the right of the midline. The spleen was identified in the left cranial abdomen following the greater curvature of the stomach. The parenchyma was homogeneous and hyperechogenic compared to the liver and kidney cortex. The stomach was in the cranial abdomen, limited cranially by the liver and caudo-laterally by the spleen. The left adrenal glands of five coatis were seen in the cranial pole of the left kidney showing hypoechogenic parenchyma without distinction of cortex and medulla. The pancreas was visualized in only two coatis. The left ovary (0.92 cm x 0.56 cm) was visualized on a single coati in the caudal pole of the kidney. The uterus, right adrenal, right ovary and intestines were not visualized. CONCLUSIONS: Ultrasound examination of the abdomen of coatis may be accomplished by following the recommendations for dogs and cats. It is possible to evaluate the anatomical and topographical relationships of the abdominal organs together with the knowledge of the peculiarities of parenchymal echogenicity and echotexture of the viscera.

Dyslipidemia in women with polycystic ovary syndrome: incidence, pattern and predictors.

One hundred forty-two women with polycystic ovary syndrome (PCOS) with an average body mass index (BMI) of 29.1 kg/m(2) and average age of 25.12 years were studied. By BMI, 30.2% were normal, 38.0% were overweight and 31.6% were obese. Thirty-one eumenorrheic women matched for BMI and age, with no evidence of hyperandrogenism, were recruited as controls. The incidence of dyslipidemia in the PCOS group was twice that of the Control group (76.1% versus 32.25%). The most frequent abnormalities were low high-density lipoprotein cholesterol (HDL-C; 57.6%) and high triglyceride (TG) (28.3%). HDL-C was significantly lower in all subgroups of women with PCOS when compared to the subgroups of normal women. No significant differences were seen in the total cholesterol (p = 0.307), low-density lipoprotein cholesterol (LDL-C; p = 0.283) and TGs (p = 0.113) levels among the subgroups. An independent effect on HDL-C was detected for glucose (p = 0.004) and fasting insulin (p = 0.01); on TG for age (p = 0.003) and homeostatic model assessment insulin resistance (p = 0.03) and on total cholesterol and LDL-C for age (p = 0.02 and p = 0.033, respectively). In conclusion, dyslipidemia is common in women with PCOS, mainly due to low HDL-C levels. BMI has a significant impact on this abnormality.

Low-dose estrogen therapy does not change postexercise hypotension, sympathetic nerve activity reduction, and vasodilation in healthy postmenopausal women.

The aim of this study was to determine whether estrogen therapy enhances postexercise muscle sympathetic nerve activity (MSNA) decrease and vasodilation, resulting in a greater postexercise hypotension. Eighteen postmenopausal women received oral estrogen therapy (ET; n=9, 1 mg/day) or placebo (n=9) for 6 mo. They then participated in one 45-min exercise session (cycle ergometer at 50% of oxygen uptake peak) and one 45-min control session (seated rest) in random order. Blood pressure (BP, oscillometry), heart rate (HR), MSNA (microneurography), forearm blood flow (FBF, plethysmography), and forearm vascular resistance (FVR) were measured 60 min later. FVR was calculated. Data were analyzed using a two-way ANOVA. Although postexercise physiological responses were unaltered, HR was significantly lower in the ET group than in the placebo group (59+/-2 vs. 71+/-2 beats/min, P<0.01). In both groups, exercise produced significant decreases in systolic BP (145+/-3 vs. 154+/-3 mmHg, P=0.01), diastolic BP (71+/-3 vs. 75+/-2 mmHg, P=0.04), mean BP (89+/-2 vs. 93+/-2 mmHg, P=0.02), MSNA (29+/-2 vs. 35+/-1 bursts/min, P<0.01), and FVR (33+/-4 vs. 55+/-10 units, P=0.01), whereas it increased FBF (2.7+/-0.4 vs. 1.6+/-0.2 ml x min(-1) x 100 ml(-1), P=0.02) and did not change HR (64+/-2 vs. 65+/-2 beats/min, P=0.3). Although ET did not change postexercise BP, HR, MSNA, FBF, or FVR responses, it reduced absolute HR values at baseline and after exercise.

Effect of sildenafil on clitoral blood flow and sexual response in postmenopausal women with orgasmic dysfunction.

OBJECTIVE: To analyze the effects of sildenafil citrate on clitoral blood flow and sexual response in postmenopausal women with orgasmic dysfunction. METHOD: In this randomized, double-blind, placebo-controlled trial 22 women received a 50-mg dose of sildenafil (n=11) or placebo (n=11) daily for 15 days. The Golombok Rust Inventory of Sexual Satisfaction (GRISS) was used for subjective evaluation of the sexual-response cycle. Clitoral blood flow was measured by color and pulse Doppler at baseline, after 1 hour of taking the first dose, and after 15 days of treatment. RESULTS: Blood flow was significantly more improved in the sildenafil than in the placebo group (P<0.05), and a positive correlation between Doppler values and GRISS scores was noted in the sildenafil group after only 15 days of treatment. CONCLUSION: Sildenafil may improve clitoral blood flow and increase the GRISS scores in postmenopausal women with orgasmic dysfunction.

A randomized, placebo-controlled trial of the effects of physical exercises and estrogen therapy on health-related quality of life in postmenopausal women.

OBJECTIVE: The purpose of this study was to evaluate the isolated and associated effects of estrogen therapy (estradiol valerate 1 mg/d orally) and physical exercise (moderate aerobic exercise, 3 h/wk) on health-related quality of life (HRQOL) and menopausal symptoms among women who had undergone hysterectomy. DESIGN: A 6-month, randomized, double-blind, placebo-controlled clinical trial with 44 postmenopausal women who had undergone hysterectomy. The interventions were physical exercise and hormone therapy (n = 9), being sedentary and hormone therapy (n = 14), physical exercise and placebo (n = 11), and being sedentary and placebo (n = 10). HRQOL was assessed by a Brazilian standard version of the Medical Outcome Study Short-Form Health Survey and symptoms by Kupperman Index at baseline and after 6 months. RESULTS: There was a decrease in symptoms in all groups, but only groups who performed physical exercise showed an increase in quality of life. Analysis of variance showed that changes in physical functioning (P = 0.001) and bodily pain (P = 0.012) scores over the 6-month period differed significantly between women who exercised and women who were sedentary, regardless of hormone therapy. Hormone therapy had no effect, and there was also no significant association between physical exercise and hormone therapy in HRQOL. CONCLUSIONS: Physical exercises can reduce menopausal symptoms and enhance HRQOL, independent of whether hormone therapy is taken.

The FMR1 premutation as a cause of premature ovarian failure in Brazilian women

The loss-of-function mutation of the FMR1 gene due to expansion of the 5' UTR CGG repeat causes the fragile X syndrome, the most frequent form of inherited mental retardation. On the other hand, the FMR1 premutation, which is transcriptionally active and produces the protein, confers an increased risk for premature ovarian failure (POF) to carrier females. Among 41 unrelated Brazilian women with idiopathic POF, we found three carriers of premutations (CGG expansionse > 59 repeats) and two carriers of high-intermediate alleles (50-55 repeats). Two premutations and two intermediate alleles were detected among the 16 familial POF cases, and one premutated woman, among the 25 sporadic cases. The premutation frequency among the familial cases (12.5 percent) differed significantly from that found in a control group of 96 unrelated Brazilian women aged > 47 years, who had not experience POF and in which no premutations or high-intermediate alleles were detected. In the search for factors influencing the probability of a premutation carrier presenting POF, another 20 unrelated premutated women with POF, from fragile X families, were included in the study. The analysis of the FMR1-linked loci DXS548 and FRAXAC1 did not indicate any association of a particular haplotype with the occurrence of POF. An effect of X-inactivation skewing was not apparent in blood cells, and POF-associated premutations showed a wide range of repeat sizes, from 59, the smallest known to expand to full mutations upon transmission to offspring, to approximately 200.

Avaliaçäo do endometrio em pacientes climatéricas / Valuation of the endometrium of climacteric patients

No período compreendido entre junho de 1986 a junho de 1988, foram estudadas na Clínica Ginecológica da Faculdade de Medicina da Universidade de Säo paulo 81 pacientes climatéricas cujas idades variaram de 40 a 55 anos (média etária 50,3 anos) as quais näo faziam uso de medicaçäo hormonal, a fim de se avaliar o tipo de endométrio de acordo com o tempo decorrido da última menstruaçäo. As pacientes foram divididas em quatro grupos: Grupo A) constituído de 50 pacientes na fase pré-menopausal com irregularidades menstruais; Grupo B) dez pacientes com um anos a um ano e onze meses de menopausa; Grupo C) 14 pacientes com dois anos a cinco anos e 11 meses de menopausa; Grupo D) sete pacientes com 6 a 15 anos de menopausa. Em todas foram realizadas biópsias múltiplas do endométrio com a cureta de Novak. Em 30 pacientes foi administrada terapêutica hormonal por quatro meses e realizado novo estudo do endométrio no quarto mês de tratamento. Os resultados revelalram: Grupo A) endométrio proliferativo, atrófico, secretor com insuficiência lútea, secretor, menstrual, hiperplásico sem atipia, hiperplásico com atipia em 18, 8, 9, 8, 1, 2, 1 casos, respectivamente; Grupo B) sete casos com endométrio atrófico, dois casos proliferativos, e, um caso com pólipo endometrial; Grupos C e D) oito e cinco casos de endométrio atrófico, respectivamente. O material foi insuficiente para diagnóstico em dois casos no Grupo D. Houve dificuldades técnicas na realizaçäo da biópsia em um, três e um caso do Grupo A, C, e D, respectivamente. Concluem os autores da importância do estudo do endométrio antes de se iniciar a terapêutica hormonal a fim de que a mesma seja adequada
