Impact of donor age on survival and fibrosis progression in patients with hepatitis C undergoing liver transplantation using HCV+ allografts.

Studies have suggested that the use of hepatitis C virus (HCV)-positive (HCV+) donor allografts has no impact on survival. However, no studies have examined the effect that HCV+ donor histology has upon recipient and graft survival. We evaluated the clinical outcome and impact of histological features in HCV patients transplanted using HCV+ livers.

Drug injury in the upper gastrointestinal tract: effects of alendronate.

Osteoporosis is a disease characterized by an increase in bone resorption and a decline in bone density, which leads to increased susceptibility to bone fractures. Long-term therapy is needed to increase bone mineral density and maintain bone strength. Safe and well-tolerated medical therapies are required for long-term maintenance.

The effect of dilute vasopressin solution on blood loss during operative hysteroscopy: a randomized controlled trial.

Objective: To assess the effect of intracervical injection of dilute (0.05 U/mL) vasopressin solution on blood loss during operative hysteroscopy.

Methods: In a randomized, double-blind study, dilute vasopressin solution or placebo (normal saline) was injected into the cervical stroma of 106 women before dilation of the cervix in preparation for operative hysteroscopy.

Large cell calcifying Sertoli tumor of the testis. Light microscopic and ultrastructural study.

Large cell calcifying Sertoli tumor of the testis was found in a 16-year-old boy who had presented with gynecomastia. Serum estrogen level, which had been elevated preoperatively, returned to normal following orchiectomy. Charcot-Bottcher crystalloids are demonstrated in the neoplastic Sertoli cells.
