Reports of uterine rupture following surgical abortion are rare but may result in hemorrhage, sepsis, and even death. In this unique case, we describe how a transabdominal pelvic ultrasound performed at the bedside by an emergency department physician identified uterine rupture with retained products of conception and led to an emergent laparotomy and hysterectomy. This case illustrates how bedside ultrasound may be used in patients presenting with abdominopelvic pain following surgical abortion to shorten the time to definitive treatment and ultimately lower the morbidity and mortality associated with a diagnosis of life-threatening uterine rupture. 相似文献

Background
Bodybuilding is a demanding sport, which requires high-volume, high-resistance weight training and augmented nutritional intake, toward an increase of overall body muscle mass accompanied by an overall decrease of body fat percentage and mass. Among bodybuilders, the use of various legal and illegal supplements is common. These supplements may be naturally occurring or man-made.Case Report
We discuss the case of a 30-year-old male bodybuilder presenting with coma due to severe hypoglycemia from unknown cause, necessitating iterative glucose infusions, which was subsequently found to be related to cryptic insulin injections.Why Should an Emergency Physician Be Aware of This?
In strength athletes, especially amateurs, the recourse to performance-enhancement drugs (e.g., insulin) is frequent. Beyond the specificity of care required for surreptitious insulin intoxication, emergency physicians should be alert to the possibility that exogenous insulin has been injected for use as an ergogenic aid by bodybuilders and others seeking to increase their body muscle mass when they encounter a patient with a decreased level of consciousness and treatment-refractory hypoglycemia. Moreover, in case of suspicion of such intoxication, the use of other illegal supplements should be screened, due to potentially associated risks of complication. 相似文献148.
