RESUMO
BACKGROUND: Smartphone apps have been successfully used to help adults prepare for colonoscopies. However, no study to date has investigated the effect of a smartphone app on pediatric colonoscopy preparation. OBJECTIVE: The aim of this study is to determine if an app (SB Colonoscopy Prep) designed to educate and guide patients through their colonoscopy preparation will yield benefits over paper-based instructions and information. METHODS: In total, 46 patients aged 5-18 years received either app-based or written material with instructions on how to take their prep medications as well as information about the colonoscopy procedure. Prep quality, the number of calls to the gastroenterology service, and patient arrival time were recorded. After the procedure, a questionnaire was given to each patient through which they graded their knowledge of the procedure both before and after receiving the app or written material. RESULTS: App users had higher mean Boston scores versus control subjects receiving written instructions (7.2 vs 5.9, P=.02), indicating better colonoscopy preps. In total, 75% (15/20) of app users and 41% (9/22) of written instruction users had preps categorized as "excellent" on the Boston scale. We found no significant differences in knowledge about the procedure (app users: 10/20 [50%], written instruction users 8/22 [36%]; P=.37), phone calls to the gastroenterology clinic (n=6 vs n=2; P=.27), or arrival times at the endoscopy suite (44 min vs 46 min before the scheduled procedure time; P=.56). CONCLUSIONS: Smartphone app use was associated with an increased number of colonoscopy preps classified as "excellent" on the Boston scale. There was no significant difference between app users and the control group regarding the number of calls to the gastroenterology clinic, patient arrival time, or patient knowledge about the procedure.

RESUMO
Foot drop has many etiologies. One rarely mentioned and often neglected reason for foot drop is an acute inversion sprain of the ankle. Over the past 14 years, a collection of 32 cases of foot drop have been compiled in our orthopaedic and physiatric practices. All cases had appropriate evaluations, including electrodiagnostic studies (electromyography and nerve conduction studies) to determine the location and type of injury. Treatment and follow-up are also discussed. Of the 32 case studies, four were caused by a straightforward acute inversion sprain of the ankle. These cases are described with the electrodiagnostic evaluations, treatments, and outcomes. Proposed mechanisms for this type of foot drop are discussed, including traction and compression of the common peroneal nerve as it winds around the neck of the fibula, and possible compression by hematoma. Surgical versus conservative treatment is described. The functional impairment associated with foot drop is detailed.
