Ovarian cancer-related angiogenesis is a complex process orchestrated by many positive and negative regulators. Many growth factors are involved in the development of the tumor-associated vasculature, and from these, endocrine gland-derived vascular endothelial growth factor (EG-VEGF) seems to play a crucial role. EG-VEGF is the first organ-specific angiogenic factor and its effects are restricted to the endothelial cells of the endocrine glands. Although EG-VEGF was detected in both normal and neoplastic ovaries, its clinical significance remains controversial. In the present study, we analyzed 30 patients with epithelial ovarian cancer, and the immunohistochemical expression of EG-VEGF was compared with the conventional clinico-pathological parameters of prognosis. Neoplastic cells of the ovarian carcinoma expressed EG-VEGF in 73.33% of the cases, as a cytoplasmic granular product of reaction. We found a strong correlation between the expression of EG-VEGF at protein level and tumor stage, grade, and microscopic type. The expression of EG-VEGF was found in patients with stage III and IV, but not in stage II. The majority of serous adenocarcinoma, half of the cases with clear cell carcinoma and two cases with endometrioid carcinoma showed definite expression in tumor cells. No positive reaction was found in the cases with mucinous carcinoma. Our results showed that EG-VEGF expression is an indicator not only of the advanced stage, but also of ovarian cancer progression. Based on these data, we concluded that EG-VEGF expression in tumor cells of the epithelial ovarian cancer is a good marker of unfavorable prognosis and could be an attractive therapeutic target in patients with advanced-stage tumors, refractory conventional chemotherapy.

Extensive burns are devastating traumatic events, with significant potential for development of complex psychosocial problems. The aim of the study was to identify and quantify these difficulties among extensive burns patients. This study was conducted at Clinical Emergency Hospital for Plastic, Reconstructive and Burns Surgery and "Bagdasar-Arseni" Emergency Hospital, in Bucharest, on 43 extensive burn patients. For each patient we developed a statistic sheet with demographic data and medical information. For data collection, subjects completed the following instruments: Hamilton Depression Scale (HAMD) and Satisfaction With Appearance Scale (SWAP). The impact variables evaluated in this study were demographic characteristic of patients, burn injury characteristics, abnormal scarring and visible scars, body image dissatisfaction and depression symptoms. Although performed on a small sample, the results of this pilot study could be a valuable starting point for future larger studies, to achieve more generalizable results on extensive burns survivor's quality of life.
