“PURPOSE: To analyze the expression of hypoxia inducible factor 1 alpha (HIF1A) and its correlation with clinical outcome in men with localized prostate cancer (PC) treated with dose escalation radiotherapy (RT) and androgen deprivation (AD). METHODS: Between 1996 and 2004, 129 PC patients who had diagnostic

biopsies pre-treatment and 24-36 months following RT were enrolled in this study. Median follow-up was 129 months. Suitable archival diagnostic tissue was obtained from 86 patients. Correlation analysis was done to assess association between HIF1A expression and clinical outcome. RESULTS: HIF1A expression was observed in 25/86 (29%) of diagnostic biopsies, and in 5/14 (36%) of post-RT biopsies. No significant association was noted between HIF1A expression and clinical and treatment

S63845 parameters. We also failed to show a significant correlation between HIF1A overexpression and outcome. A borderline significant relationship was observed between expression of HIF1A and overall survival (OS) (HR 0.03, p = 0.08). CONCLUSION: To our knowledge this is the first study assessing the pattern of change of HIF1A staining in biopsies of patients prior and following treatment. While we did not find significant variations in the expression of HIF1A following radio-hormone therapy, a high HIF1A expression was unexpectedly associated with a borderline improved OS.”
“Purpose: The purpose of this report was to describe a case of choroidal detachment after an uneventful intravitreal injection using a 30-gauge needle.\n\nMethods: An 88-year-old patient with ATM inhibitor SRT2104 acute onset of neovascular age-related macular degeneration developed a choroidal detachment after an uneventful intravitreal injection in the infero-temporal aspect of the fundus.\n\nResults: The patient described no symptoms related to the chorioretinal detachment. Additional intravitreal injections were required to treat an active subfoveal

choroidal neovascularization. These injections were placed at the contralateral side in the supero-nasal quadrant. She was closely watched on a 2-week follow-up schedule. The choroidal detachment remained asymptomatic for the patient and resolved spontaneously, and the best corrected visual acuity improved from 0.2 to 0.63 during a 6-month follow-up. A mild hyperpigmentation remained at this location.\n\nConclusion: Asymptomatic choroidal detachments may occur after intravitreal injection. Although treatment was not needed, additional injections should be avoided in the same quadrant until the detachment has resolved.”
“Background and aim: Subtle changes in hypothalamic-pituitary-adrenal (HPA) axis of subjects with non-functioning adrenal adenoma may be associated with endothelial alterations. We sought to investigate endothelial function, visceral adiposity and osteoprotegerin (OPG) and interleukin-18 (IL-18) levels in subjects with non-functioning adrenal adenomas.
