Do We Need Routine Postoperative Prophylactic Oral Antibiotics in Elective Foot and Ankle Surgery?

Background: Previous studies about antibiotic prophylaxis in foot and ankle surgery have focused on perioperative intravenous administration, with few studies reporting on the efficiency of postoperative oral antibiotics. The purpose of this study is to investigate differences in the rate of postoperative infection and wound complications between patients with and without postoperative oral antibiotics and to identify independent risk factors for these complications following foot and ankle surgeries.

Methods: A retrospective review of all elective foot and ankle surgeries with at least a 6-month follow-up was performed over a 2-year time span.

Fluid interactions that enable stealth predation by the upstream-foraging hydromedusa Craspedacusta sowerbyi.

Unlike most medusae that forage with tentacles trailing behind their bells, several species forage upstream of their bells using aborally located tentacles. It has been hypothesized that these medusae forage as stealth predators by placing their tentacles in more quiescent regions of flow around their bells. Consequently, they are able to capture highly mobile, sensitive prey.
