Adult intussusception is an uncommon cause of abdominal pain and poses diagnostic challenges for emergency physicians due to its varied presenting symptoms and time course. We report a case of chronic colocolic intussusception secondary to a lead point submucosal lipoma. Dedifferentiating intussusception with or without a lead point is important in determining appropriate management.

Studies suggest that there is an association between weather and cardiovascular disease (CVD) related visits in emergency departments (ED). ⋯ We found an association between rapid weather changes on the day before ED admission and ED visits due to CVD. In conclusion, a drop in temperature and an increase or decrease in atmospheric pressure and relative humidity are associated with a slight increase in CVD admissions. However, the observed significant effects seem to be too small to draw any conclusions in terms of ED capacity due to weather changes.

It is unclear if additional computerized tomography (CT) imaging is warranted after injuries are identified on CT in blunt trauma patients. The objective of this study was to determine the incidence and significance of injuries identified on secondary CT imaging after identification of injuries on initial CTs in blunt trauma patients. ⋯ While a significant proportion of patients (18%) had injuries on secondary CT, only 1.7% of patients had a resultant major management change. Future research is warranted to determine the need for additional CT imaging after an initial selective imaging strategy in blunt trauma patients.

Catamenial hemothorax is a rare manifestation of thoracic endometriosis syndrome. It is commonly seen associated with pelvic endometriosis in nulliparous reproductive-age women. Most cases are minor and self-limiting. We present a case of a 32-year-old woman who presented with prolonged worsening dyspnea and was found to have a massive hemothorax on evaluation.

Randomized Controlled Trial Comparative Study
Comparison of high-flow nasal cannula oxygen therapy and conventional reserve-bag oxygen therapy in carbon monoxide intoxication: A pilot study.
High-flow nasal cannula oxygen (HFNC) creates a positive pressure effect through high-flow rates compared to conventional oxygen therapy. The purpose of this human pilot study is to compare the effects of HFNC and conventional oxygen therapy on the rate of carbon monoxide (CO) clearance from the blood in patients with mild to moderate CO poisoning. ⋯ In this pilot randomized controlled trial study, HFNC therapy did not reduce fCOHbt1/2 compared to NBO2 therapy but could be beneficial in maintaining a constant fCOHbt1/2 as well as in reducing fCOHbt1/2 in mild CO poisoning patients compared to conventional NBO2 therapy. However, further studies with a larger number of patients are needed to establish HFNC therapy as an alternative therapy for CO poisoning patients.
