Computer-assisted evaluation of Mandibular Cortical Width (MCW) index as an indicator of osteoporosis.

Background: To assess the diagnostic accuracy of mandibular cortical width (MCW) as an indicator of the presence of osteoporosis.

Materials And Methods: The study included 343 women between 45-75 years of age. After informed consent, all subjects underwent dual energy X-ray absorptiometry (DXA) of the hip and the lumbar spine (L1 to L4) in order to establish a gold standard diagnosis of osteoporosis and an orthopantomogram (OPG).

[Testicular microlithiasis and Leydig cell proliferation in Wistar rats underwent Fowler-Stephens procedure].

Objectives: The present study investigates the outcome of Fowler-Stephens operation in prepubertal Wistar rats focused on microlithiasis and Leydig cell hyperplasia development.

Methods: Thirty-eight (38) animals underwent laparoscopic Fowler-Stephens operation on the right testis (8 of them formed the control group) and 6 of them additional contra-lateral orchectomy. The testes were examined histological 9,30,70 and 90 days later, while ultrasound study was perfomed a day earlier.
