Revista Brasileira de Ginecologia e Obstetrícia , 2012, DOI: 10.1590/S0100-72032012000200009
Abstract: purpose: to characterize patients with indeterminate values of hyperprolactinemia (peg test for the identification of macroprolactinemias with recovery between 30 and 65%) (prli) or macroprolactinemia (prlm), in relation to clinical characteristics, such as the presence or absence of symptoms, as well as their intensity and variation, and the presence or absence of central nervous system tumors. methods: this is a cross-sectional retrospective survey of records of 24 patients with hyperprolactinemia, in reproductive ages, with prolactin >25 ng/dl. eleven women with prlm and 13 with prli were included. records from the two groups were extracted for analysis: age, parity, body mass index, presence of galactorrhea, infertility, and central nervous system tumor. anthropometrics data were expressed as mean and standard deviation. to compare groups regarding the presence of central nervous system tumor, galactorrhea, as well as infertility we used the student's t-test. results: galactorrhea was more prevalent in patients with prli (p=0.01). seventy percent of women with prli presented pituitary tumor (microprolactinoma), whereas this finding was evident in 17% of the prlm group (p=0.04). among the patients with and prlm prli, nine were not investigated with the image of the central nervous system because they have low levels of prolactin (five carriers and four prlm prli). there were no significant differences regarding the occurrence of infertility or irregular menstrual cycles between groups. discussion: women with intermediate hyperprolactinemia present more galactorrhea symptoms as well as central nervous system tumors than women with macroprolactinemia.

Abstract: objective: verify the relation between hpv 16/18 antibodies and the association with cervical cytology findings in adolescents and young women. methods: a cross sectional study with 541 healthy and sexually active women from 15 to 25 years of age was carried on from september to november 2000. at gynecological examination, a cervical sample on liquid-base for cytology-testing and a bblood sample for elisa identification of hpv 16 and 18 antibodies were collected and sent to a reference laboratory in belgium. statistical analysis estimated the prevalence and prevalence ratio with a 95% confidence interval. results: of these young women, 150 (27.7%) were seropositive: 79 (14.6%) to hpv 16 antibody; 35 (6.4%) to hpv 18 antibody and 36 (6.6%) to both hpv 16/18 antibodies. cytological abnormalities were detected in 107 cases (20.5%): 63 presented with atypical squamous cells of undetermined significance (ascus), 41 were suggestive of low grade squamous intra-epithelial lesion (lgsil) and 3 of high grade squamous intra-epithelial lesion (hgsil). prevalence of abnormal cytology with a positive serology was only 1.75 times that of prevalence of abnormal cytology with a negative serology. detection of abnormal cytology was not correlated with positive serology. conclusion: results of this study indicate a high prevalence of hpv 16 and 18 in young healthy women which showed no relation to the abnormal findings of cytology smears.

Abstract:

Introduction: Pelvic exenteration can cure recurrent gynecological malignancies. However, treatment morbidity is over 50% in radiated pelves. We evaluated the outcome, the morbidity and the quality of life after exenteration. Methods: Patients who underwent an exenteration for recurrent cervical or endometrial cancer in our institution between 1999 and 2011 were retrieved. Survival rates were calculated according to Kaplan-Meier method and compared using the logrank test. The EORTC QLQ-C30 and QLQ-CX24 questionnaires were sent to patients alive in January 2012. Results: We identified 25 patients: 17 (68%) had cervical cancer and 8 (32%) endometrial cancer. 92% of them had received radiotherapy previously. All patients had a central pelvic recurrence, within a median time of 30 months [4 - 384] from initial treatment. Early complications requiring a re-laparotomy occurred in 9 patients (36%). Late complications included 2 (8%) fistulas, 2 (8%) occlusion and 1 (4%)

ureteral stenosis. Complete resection was obtained in 92% of patients. Disease Free and Overall survival rates were better in cervical rather than in endometrial cancer (median DFS in months 17 [2 - 145] vs 9.5 [3 - 21], p = 0.064, median OS in months 20 [2 - 145] vs 13 [4 - 42], p = 0.019). 69% of patients answered the quality of life questionnaires. Mean global quality of life score was 45 on a scale of 0 - 100, none of the patients had a sexual activity. Conclusions: Morbidity of exenteration remains high and quality of life is altered. Endometrial cancer is associated with a poorer prognosis. In those patients, exenteration should be put in balance with best supportive care.

Open Journal of Endocrine and Metabolic Diseases (OJEMD) , 2013, DOI: 10.4236/ojemd.2013.31005
Abstract:

Background: This study aims to understand the relationship between menopausal status and the presence of Metabolic Syndrome in women from 40 to 65 years, as well as to describe the distribution of each component of Metabolic Syn- drome according to sample characteristics. Methods: A cross-sectional study was conducted with 551 women treated at a clinic in southern Brazil. MetS and its components were defined according to NCEP-ATP III and menopausal status as pre, peri, and post-menopause. Prevalences of menopausal status and of MetS and its components were calculated. Estimates of prevalence ratios crude and adjusted with confidence intervals of 95% were calculated by Poisson Regression with robust variance. Demographic, socioeconomic, behavioral, and reproductive characteristics were considered as potential confounding factors in multivariable models based on a conceptual framework of MetS determination. Results: The prevalence of Metabolic Syndrome in the sample was 56.1% (CI95%: 51.9 to 60.2), being more common among older women (56 to 65 years), with low education, menarche < 11 years old, with three or more pregnancies and in the post-menopausal period. In multivariate analysis, there was an increase of prevalence ratios when comparing perimenopause and post-menopause with pre-menopause; however, the confidence intervals include the unit. Regarding the analysis of isolated components in the sample, the most prevalent altered components were: hypertension (84.8%; CI95%: 81.7 to 87.8), waist circumference (66.4%; CI95%: 62.5 to 70.4) and HDL cholesterol (51.7%; CI95%: 47.5 to 55.9). There was a linear increase on mean blood glucose through menopausal status. Conclusions: Our study indicates variation on the distribution of MetS and each component according to menopausal status and other women characteristics. Future studies on MetS should also have foresight to use this type of approach to improve understanding and targeting of actions and programs focusing on women in this period of life.

Physical transport properties of marine microplastic pollution

Biogeosciences Discussions , 2012, DOI: 10.5194/bgd-9-18755-2012
Abstract: Given the complexity of quantitative collection, knowledge of the distribution of microplastic pollution in many regions of the world ocean is patchy, both spatially and temporally, especially for the subsurface environment. However, with knowledge of typical hydrodynamic behavior of waste plastic material, models predicting the dispersal of pelagic and benthic plastics from land sources into the ocean are possible. Here we investigate three aspects of plastic distribution and transport in European waters. Firstly, we assess patterns in the distribution of plastics found in fluvial strandlines of the North Sea and how distribution may be related to flow velocities and distance from source. Second, we model transport of non-buoyant preproduction pellets in the Nazaré Canyon of Portugal using the MOHID system after assessing the density, settling velocity, critical and depositional shear stress characteristics of such waste plastics. Thirdly, we investigate the effect of surface turbulences and high pressures on a range of marine plastic debris categories (various densities, degradation states and shapes tested) in an experimental water column simulator tank and pressure laboratory. Plastics deposited on North Sea strandlines varied greatly spatially, as a function of material composition and distance from source. Model outputs indicated that such dense production pellets are likely transported up and down canyon as a function of tidal forces, with only very minor net down canyon movement. Behaviour of plastic fragments under turbulence varied greatly, with the dimensions of the material, as well as density, playing major determining roles. Pressure was shown to affect hydrodynamic behaviours of only low density foam plastics at pressures ≥ 60 bar.
