Massive edema of the ovary: a case report and review of the pertinent literature.

BACKGROUND: Massive edema of the ovary is a rare entity affecting mainly young women. It is often misdiagnosed for a malignancy, posing the young patient at risk for over-treatment with resultant loss of hormonal function and fertility. CASE: A 13-year-old premenarchal girl presented with a large solid pelvic mass after recurrent episodes of self-limited abdominal pain. With a working diagnosis of malignant ovarian tumor, an exploratory laparotomy was done in which a twisted ovarian mass was found and excised completely. Pathological examination of the mass revealed massive edema of the ovary with hemorrhagic necrosis. CONCLUSION: After extensive review of the literature, it seems most cases were over-treated, as was ours. This entity should be suspected in women at the fertile age range with solid enlargement of the ovary and definite treatment should be undertaken only after confirmed pathological diagnosis. Conservative treatment is feasible and should be the rule in these cases, where fertility preservation is mandatory

Portal hypertension is associated with modulation of regulatory T cells

Background: Portal hypertension is a complication of liver cirrhosis. The portal vein drains the spleen and the intestines, which are both rich in inflammatory mediators. Portal hypertension- induced stress within these organs that may result in pro-inflammatory changes. The association of these changes with regulatory T cells was not addressed before. Aim: Our aim is to investigate the involvement of some subsets of regulatory T cells in portal hypertension. Methods: In the current study we used the partial portal vein ligation model to demonstrate differences in the distribution of regulatory T cells within the portal vein and the inferior vena cava associated with portal hypertension. Results: We show that CD4+CD25+FoxP3+ regulatory T cells are significantly ( P <0.05) increased only in the inferior vena cava of partial portal vein ligation-rats. The development of portal hypertension was associated with the reversal of the distribution patterns in the portal vein and inferior vena cava for both CD4+ and CD8+ cells. We further show that in naïve rats CD4+IL17+ cells were significantly ( P <0.05) and specifically enriched in inferior vena cava compared to the portal vein. Conclusions: These novel findings support the involvement of regulatory T cells in the inflammatory signals accompanied with acute portal hypertension
