Hospital cost of treating early dislocation following hip arthroplasty.

Dislocation is a frequent and costly complication of hip arthroplasty. The purpose of this study was to assess the financial impact on the treating institution of this complication in patients with primary hemiarthroplasty (HA), total hip arthroplasty (THA) and revision surgery (RTHA). Between October 2001 and August 2009, 2014 consecutive hip arthroplasties were performed at our institution, of which 87 (18 HA, 44 THA and 25 RTHA) dislocated within 6 weeks of the primary operation.

Uniportal video-assisted thoracic surgery for primary spontaneous pneumothorax: clinical and economic analysis in comparison to the traditional approach.

We aimed to verify the clinical and economic effects of uniportal video-assisted thoracic surgery (VATS) in patients with primary spontaneous pneumothorax (PSP) compared to traditional three-port VATS technique. We analyzed 51 consecutive patients (23 three-port VATS and 28 uni-port VATS), treated by bullectomy and pleural abrasion, to detect differences between the two groups with regard to intraoperative management, postoperative course, pain, paraesthesia and costs. Data about pain and paraesthesia were collected by telephonic interview within a minimum follow-up period of six months.

Responsiveness of Dupuytren's disease fibroblasts to 5 alpha-dihydrotestosterone.

Purpose: We recently showed that androgen receptors are expressed in Dupuytren's contracture. The aim of the present work was to test the responsiveness of Dupuytren's fibroblasts to 5 alpha-dihydrotestosterone (5 alpha-DHT), the active form of testosterone.

Results: Cultured palmar fascia cells from 10 patients with Dupuytren's contracture and 4 normal subjects were exposed to 5 alpha-DHT (10 or 100 ng/mL) for 1, 3, 7, and 15 days.
