Prevention and management of osteoporosis in men receiving androgen deprivation therapy: a survey of urologists and radiation oncologists.

Objectives: To determine the current practice of clinicians in the diagnosis and management of osteoporosis among men taking androgen deprivation therapy (ADT), because ADT leads to decreased bone mineral density (BMD) and fractures.

Methods: We sent out a survey to Canadian urologists and radiation oncologists. The survey included questions about BMD testing, treatment practices, referral patterns, and risk of osteoporosis.

A model cochlear partition involving longitudinal elasticity.

This paper addresses the issue of longitudinal stiffness within the cochlea. A one-dimensional model of the cochlear partition is presented in which the resonant sections are coupled by longitudinal elastic elements. These elements functionally represent the aggregate mechanical effect of the connective tissue that spans the length of the organ of Corti.
