Laparoscopic Nissen fundoplication effectively relieves symptoms in patients with laryngopharyngeal reflux.

Introduction: The utility of laparoscopic Nissen fundoplication in the treatment of laryngopharyngeal reflux symptoms remains controversial. We hypothesized that a carefully selected population with these symptoms would benefit from antireflux surgery.

Materials And Methods: Sixty-one consecutive patients have undergone antireflux surgery for laryngopharyngeal reflux at a single institution.

Immunomodulatory effects of dehydroepiandrosterone in proestrus female mice after trauma-hemorrhage.

Studies indicate that administration of the adrenal steroid dehydroepiandrosterone (DHEA) after trauma-hemorrhage in male mice improved cellular immune functions and reduced mortality rates from subsequent sepsis. There is evidence, however, that DHEA is converted to estrogens in males and that estrogens are immunoprotective after trauma-hemorrhage (TH). In contrast, DHEA in females can be converted to testosterone that has deleterious effects on immune functions.
