Purpose: to evaluate the effects of oophorectomy and pinealectomy on the ingestion of water and NaCl solution by adults female rats. Methods: forty-eight adult virgin female rats (Wistar EPM 1) weighing 200 g were kept on routine laboratory care and fed water and Purina rat chow ad libitum. The animals were random by divided into four groups: GI - maintained without manipulation as a control group (n = 20); GII - submitted to bilateral oophorectomy (n = 8); GIII - submitted to pinealectomy (n = 12); GIV - submitted to bilateral oophorectomy and pinealectomy (n = 8). All animals were maintained in individual cages. After three weeks the cycle phase was daily determined by vaginal smears and the volume of water and NaCl (0.25 M) solution was daily recorded for approximately three weeks. Results: the main results were: 1) rats submitted to pinealectomy alone presented a greater frequency of the estrous phase, some of these undergoing persistent estrus; 2) the liquid ingestion (water and saline solution) did not alter during the phases of the estrous cycle; 3) rats submitted to oophorectomy presented greater water ingestion and after pinealectomy water consumption returned to normal levels; 4) the oophorectomized and pinealectomized animals and those only oophorectomized showed reduction in the average consumption of saline solution. Conclusions: the data suggest that the ovaries and the pineal gland could have effects on the ingestion of salt and water in adult rats.

The aim of this study was to evaluate the health aspects of Brazilian women older than 65 years of age.
This was a retrospective study that included 1,001 Brazilian women cared for in the gynecological geriatric outpatient office of our institution. We report a crosssectional analysis of female adults aged over 65 years, including data on demographics, clinical symptoms such as vasomotor symptoms, associated morbidities, physical examination and sexual intercourse. We used the chi-squared test to assess the data.
The age of the patients on their first clinic visit ranged from65 to 98 years, with a mean age of 68.56 ± 4.47 years; their mean age at the time of natural menopause was 48.76 ± 5.07 years. The most frequent clinical symptoms reported during the analyzed period were hot flashes (n = 188), followed by arthropathy, asthenia, and dry vagina. The most frequent associated morbidities after 65 years of age were systemic arterial hypertension, gastrointestinal disturbance, diabetes mellitus, and depression, among others. The assessment of the bodymass index (BMI) found decreases inBMIwith increased age. At the time of the visit, 78 patients reported sexual intercourse. The majority of women reporting sexual intercourse (89.75%, n = 70) were between 65 and 69 years of age, 8.97% (n = 7) were between 70 and 74 years of age, and only 1.28% (n = 1) of those were aged older than 75 years.
Our findings suggested that vasomotor symptoms can persist after 65 years of age. There was a significant decrease in sexual intercourse with increased age. The cardiovascular disturbances in our study are health concerns in these women.

PURPOSE: to compare the results of hysterosonography with those of hysteroscopy and the histopathologic study in postmenopausal women. METHODS: hysterosonography, hysteroscopy and endometrial biopsy were performed in 59 women who had an endometrial echo over 4 mm, age above 40 years and amenorrhea over one year, and whose follicle-stimulating hormone levels were over 35 mIU/mL. Patients using hormones were excluded, as well those in whom it was impossible to perform histerosonography, histeroscopy or endometrial biopsy. The statistical analysis was performed using the nonparametric "G"-Cochran and McNemar tests. In addition, sensitivity and specificity, as well as positive and negative predictive values were determined. The value of 0.05 or 5% for rejection level of the null hypothesis was applied. RESULTS: the agreement rates of hysterosonographic results compared to hysteroscopy and histopatology were 94.8 ande 77.6%, respectively. Sensitivity and specificity of hysterosonographic evaluation of the abnormal endometrial cavity were 98 and 75%, respectively, when compared to hysteroscopy. In addittion, positive and negative predictive values of hysterosonography were 96 and 86%, respectively. When the histopathologic study was used as the gold standard, sensitivity and specificity were 98 and 33%, with positive predictive value of 76% and negative predictive value of 86%, for the detection of the endometrial cavitary changes. One great concern were the histopathologic results of two patients with uterine synechia who showed endometrial hyperplasia. Also, one patient was diagnosed as normal using histerosonography and the histopatological result showed simple hyperplasia. CONCLUSIONS: our data suggest that hysterosonography presented good sensitivity as compared with hysteroscopy. However, uterine synechia is the great limitation of this method as compared with histopathology.
