Review Case Reports
Toothpick injury mimicking renal colic: case report and systematic review.
We describe a case of a patient with left flank pain that was caused by a perforation in the splenic flexure of the colon by a toothpick. We conducted a systematic review of the literature to examine the nature of injuries caused by ingested toothpicks. Articles were analyzed for the following outcome variables: presenting complaint, site of injury, recollection of toothpick ingestion, time to presentation, findings from imaging studies, and mortality. ⋯ The definitive diagnosis was most commonly made at laparotomy (53%), followed by endoscopy (19%). Overall mortality was 18%. Ingested toothpicks may cause significant gastrointestinal injuries, and must be treated with caution.

To determine the accuracy of the Esophageal Detector Bulb (EDB) in the aeromedical setting, we conducted a prospective, observational study of all intubated patients transported by an aeromedical program over two years. Flight personnel recorded the results of the EDB, clinical examination, pulse oximetry, and capnography (ETCO(2)). Endotracheal tube position was confirmed by prehospital ETCO(2) or by the receiving emergency physician. ⋯ The EDB correctly identified four of five esophageal intubations and 96 of 99 tracheal intubations. The sensitivity and specificity of the EDB in the detection of an esophageal intubation were 80% (95% CI, 38-96%) and 97% (95% CI, 92-99%), respectively, and the overall accuracy was 96% (95% CI, 90-98%). The EDB augments the ability of an aeromedical crew to determine endotracheal tube position, but its results must be carefully interpreted in the context of other available means of confirmation of endotracheal tube position.

Emergency Medical Services (EMS) agencies are increasingly being held to an ambulance response time (RT) criterion of responding to a medical emergency within 8 min for at least 90% of calls. This recommendation resulted from one study of outcome after nontraumatic cardiac arrest and has never been studied for any other emergency. This retrospective study evaluates the effect of exceeding the 8 min RT guideline on patient survival for victims of traumatic injury treated by an urban paramedic ambulance EMS system and transported to a single Level I trauma center. ⋯ After controlling for other significant predictors, there was no difference in survival after traumatic injury when the 8 min ambulance RT criteria was exceeded (mortality odds ratio 0.81, 95% CI 0.43-1.52). There was also no significant difference in survival when patients were stratified by injury severity score group. Exceeding the ambulance industry response time criterion of 8 min does not affect patient survival after traumatic injury.

A prior study evaluated the efficacy of a dog laboratory to teach residents chest tube thoracostomy. This study evaluated a similarly structured program using human cadavers. A prospective repeat measure study of chest tube thoracostomy placement training was performed in a university laboratory setting using human cadavers. ⋯ The written test scores improved for every participant. Mean times for procedure completion improved from 86 sec to 34 sec during the first session, and remained stable over 4 attempts from 30 sec to 32 sec during the second session. This approach to teaching clinical procedures should be considered for Emergency Medicine residency programs and for continuing education courses that emphasize procedural skills.

This study sought to determine if obtaining an unenhanced abdominopelvic computed tomography (UHCT) scan alters the disposition of patients presenting to the Emergency Department (ED) with signs and symptoms of acute appendicitis. A convenience sample of 101 patients presenting with a clinical picture suggestive of appendicitis were prospectively enrolled. Emergency physicians (EPs) and general surgeons independently recorded their anticipated disposition of each patient as: discharge, admit for observation, or admit for appendectomy. ⋯ CT scan revealed alternative diagnoses in 20 patients (19.8%). UHCT scanning significantly alters patient disposition, and significantly increases the number of operative interventions performed in patients with suspected appendicitis. UHCT scanning may also identify alternate pathology that clinically mimics appendicitis.
