Expression of vascular endothelial growth factor and microvascular density assessment in different histotypes of basal cell carcinoma.

Purpose: In this study, we investigated the expression of vascular endothelial growth factor (VEGF) and tumor microvascular density (MVD) in different histotypes of basal cell skin carcinoma (BCC).

Methods: We used a total 101 histological archival specimens, including superficial, nodular, cystic, keratinocytic, adenoid infiltrative types and cases of metatypical BCC. Routine hematoxylin/eosin (H&E) and immunohistochemical ABC method with NOT AE1/AE3, anti VEGF anti CD34 antibodies were used.

Arteriovenous fistulas and digital hypoperfusion ischemic syndrome in patients on hemodialysis.

Aim: To determine survival parameters as well as characteristics of patients with this syndrome.

Methods: The investigation was conducted over a period of eight years, as a prospective, non-randomized, clinical study which included 204 patients, treated by chronic hemodialysis. Most patients received hemodialysis 12 h per week.
