Extensive Recontouring of the Femoral Head with Osteochondral Allografting: A Case Report with Histological and MicroCT Analysis.

Morphological abnormalities such as cam deformity or growth disturbances can have a detrimental effect on the smooth function of the hip joint. This case reports an attempt to salvage the hip joint of a young patient with a posttraumatic growth disturbance of the femoral head using a fresh osteochondral allograft. This treatment has been used very rarely in the femoral head due to the presumed tenuous blood supply of the head and the perceived risk of nonunion or progressive avascular necrosis.

Granular cell tumor of the urinary bladder with pseudoepitheliomatous hyperplasia and colocalization with adenocarcinoma.

Granular cell tumor of the bladder is exceptionally rare, with only 11 cases reported in the published reports. Pseudoepitheliomatous hyperplasia of the overlying squamous epithelium has been observed in non-bladder granular cell tumors. We herein report the first case of bladder granular cell tumor to exhibit pseudoepitheliomatous hyperplasia.

Occult pretransplantation systemic inflammation and posttransplantation vascular changes in a primate arterial allograft model.

Background: Occult systemic inflammation, as manifested by increased levels of C-reactive protein (CRP), identify patients at increased risk for renal allograft rejection. The mechanisms linking occult systemic inflammation to these adverse outcomes remain unclear. The purpose of this study was to examine the anatomic and physiologic effects of occult pretransplantation systemic inflammation on posttransplantation allograft outcome in a nonhuman primate model.
