Tractional retinal detachment after intravitreal injection of bevacizumab in proliferative diabetic retinopathy.

Purpose: To assess the short-term complications of a single dose of intravitreal bevacizumab in patients with proliferative diabetic retinopathy (PDR).

Methods: Retrospective review of 343 patients with PDR who were treated with intravitreal injection of bevacizumab (2.5 mg/0.

Cellular proliferative fraction measured with topoisomerase IIalpha predicts malignancy in endocrine pancreatic tumors.

Context: Endocrine pancreatic tumors (EPTs) are rare lesions with varying biological behavior. Establishing malignancy is a challenge for clinicians and pathologists.

Objective: To establish the role of proliferative, apoptotic, angiogenic, and hormonal markers as predictors of malignancy in EPTs.
