Bone loss after total hip arthroplasty.

The aim of the present study is to evaluate periprosthetic bone loss and to compare it with the bone loss in other areas of the body. We also aim to shed light on the course of bone mineral density (BMD) in patients with cemented femoral prosthesis in comparison with those with uncemented ones. We analyzed the BMD using dual-energy X-ray absorptiometry (DEXA) in a consecutively recruited convenience sample of 50 patients with cemented and uncemented total hip arthroplasty (THA).

Pulmonary resection after curative intent radiotherapy (>59 Gy) and concurrent chemotherapy in non-small-cell lung cancer.

Background: Pulmonary resection after chemotherapy and concurrent full-dose radiotherapy (>59 Gy) has previously been associated with unacceptably high morbidity and mortality. Subsequently neoadjuvant therapy protocols have used reduced and potentially suboptimal radiotherapy doses of 45 Gy. We report a series of 40 patients with locally advanced non-small-cell lung cancer who successfully underwent pulmonary resection after receiving greater than 59 Gy radiation and concurrent chemotherapy.
