To compare ondansetron, metoclopramide, diphenhydramine, and placebo in order to determine which anti-emetic is most efficacious as a "rescue therapy" for pediatric patients ages 3-18 who have post-operative vomiting after a standardized prophylactic regimen of ondansetron and dexamethasone. We hypothesize that anti-emetics with a different mechanism of action than the prophylactic regimen will be the most effective "rescue therapy" in children having surgery in an ambulatory surgery center. 1. Problem: Despite commonly-used anti-emetics for prophylaxis, some children still go on to develop post-operative vomiting (POV). Goal: To determine which anti-emetic--ondansetron, metoclopramide, diphenhydramine, or placebo--is most efficacious for pediatric patients in this situation. 2. Hypothesis: Anti-emetic medications that have a different mechanism of action than the prophylactic regimen will be the most efficacious "rescue therapy." 3. Hypothesis: Metoclopramide at the dose of 0.5 mg/kg (max dose 20 mg) will be more effective than ondansetron, diphenhydramine, or placebo as "rescue therapy."

The goal of this study is to identify the genes that contribute to susceptibility to recurrent/persistent middle ear disease. Five hundred families with at least 2 children who have undergone tympanostomy tube insertion will be enrolled.

This study will adapt Problem Solving Therapy (PST) for individuals with mild cognitive impairment (MCI) as an intervention for preventing major depression (DEP). PST will be modified so as to be provided to both MCI probands as well as their support person. The primary aim is to examine the effectiveness of PST in individuals with MCI and the support person, at preventing DEP over 12 mos. in MCI probands. We also will examine the effect of exercise on preventing depression.
