In children with suspected acute gastroenteritis there was no significant association with the rate of return visits in those who were sent home with a prescription for ondansetron and those who were not.

Neither droperidol 1.25mg IV nor ondansetron 8mg IV was better than placebo in achieving an 8mm reduction in nausea on visual analog scale (VAS). But ondansetron was slightly better than droperidol and placebo for overall mean nausea reduction and in patients experiencing the desired effect.

Probiotics decrease the risk of C. difficile infection in adults and children taking antibiotics and may reduce overall adverse events like cramping, nausea, or diarrhea.

After almost twenty years as a doctor, constantly reading, it never ceases to amaze me how much I still don't know.  One of the highlights of my job is working with great residents who also teach me.  This week was no exception.  Here are two things I learned from our residents this week.
