As representações do feminino em As brumas de Avalon, de Marion Zimmer Bradley

This present work is a theoretical and qualitative research divided into three chapters that aims to demonstrate how the representations of the female in the book The Mists of Avalon (1982), writing by Marion Zimmer Bradley, dialogues and revises the tradition of cavalry novels on the Arthurian legend, particularly Thomas Malory's Le Morte D'Arthur (1485) which brings the female from the images ideologically constructed of angel and monster. Bradley innovate the Matter of Britain when she created a version of the Arthurian myth following a perspective guided on the female. From the analysis of the history of Bradley's writing as well as the historical context of the development of feminism and the feminist criticism in which she wrote will be sought-point as The Mists of Avalon part of the tradition, but reframes the traditional episodes in order to deconstruct the patriarchal sense and the male images about the feminine

Interferon Alpha-2B and liver resection to treat multifocal hepatic epithelioid hemangioendothelioma: A relevant approach to avoid liver transplantation

Background. Hepatic epithelioid hemangioendothelioma is a rare malignant tumor of vascular origin with frequent multifocal appearance. Liver resection may cause tumor spread. Liver transplantation has been indicated for unresectable nodules. We hypothesized that adjuvant interferon treatment is effective to prevent metastasis after liver resection. We report a case of multifocal hepatic epithelioid hemangioendothelioma successfully treated with interferon pulse therapy and bilobar hepatic resection.Methodology. CT scan and magnetic resonance imaging diagnosed three nodules in the liver (segments IV, VI and VII). Histopathology and specific immunostaining of a percutaneous nodule biopsy confirmed the diagnosis of hepatic epithelioid hemangioendothelioma. The treatment protocol included daily interferon alpha 2b 9 weeks before and 1 week after resection of liver segments IV, VI and VII.Results. The postoperative outcome was complicated by a self-limited biliary fistula. The patient remains tumor free at 3 years after liver resection and currently enjoys excellent health.Conclusion. Interferon pulse therapy and hepatic resection was a good option to treat multifocal bilobar hepatic epithelioid hemangioendothelioma; it may prevent metastasis dissemination.

Easiness of use and validity testing of VS-SENSE device for detection of abnormal vaginal flora and bacterial vaginosis

Accessing vaginal pH is fundamental during gynaecological visit for the detection of abnormal vaginal flora (AVF), but use of pH strips may be time-consuming and difficult to interpret. The aim of this study was to evaluate the VS-SENSE test (Common Sense Ltd, Caesarea, Israel) as a tool for the diagnosis of AVF and its correlation with abnormal pH and bacterial vaginosis (BV). The study population consisted of 45 women with vaginal pH ≥ 4.5 and 45 women with normal pH. Vaginal samples were evaluated by VS-SENSE test, microscopy and microbiologic cultures. Comparing with pH strips results, VS-SENSE test specificity was 97.8% and sensitivity of 91%. All severe cases of BV and aerobic vaginitis (AV) were detected by the test. Only one case with normal pH had an unclear result. Concluding, VS-SENSE test is easy to perform, and it correlates with increased pH, AVF, and the severe cases of BV and AV.
