The effect of changes in Medicare reimbursement on the practice of office and hospital-based endoscopic surgery for bladder cancer.

Background: Procedures performed in the office offer potential cost savings. Recent analyses suggest, however, that a fee-for-service system may incentivize subscale operations and, thus, contribute to excessive spending. The authors of this report sought to characterize changes in the practice of office-based and hospital-based endoscopic bladder surgery after 2005 increases in Medicare reimbursement.

Skin preparation for the prevention of surgical site infection: which agent is best?

Clomiphene citrate and enclomiphene for the treatment of hypogonadal androgen deficiency.

Hypogonadism has a number of important clinical consequences related to androgen deficiency and impaired spermatogenesis. The cause of this condition is multifactorial and can result from hypothalamic, pituitary or gonadal dysfunction as well as factors that affect hormonal signaling along the hypothalamic-pituitary-gonadal axis. While testosterone replacement is the most common treatment, it can paradoxically lead to infertility, and may be a less physiologic therapy for patients with secondary hypogonadism due to pituitary dysfunction.
