Choroid detachment is a rare disease process that has a multitude of etiologies; usually related to recent ophthalmological surgery, eye trauma, corneal ulcers, or intraocular pressure-lowering agents. Point-of-care ocular ultrasound has high utility and accuracy in diagnosing pathology of the eye. ⋯ We present a case of a patient who presented with vision loss caused by a choroid detachment diagnosed on point-of-care ultrasound because fundoscopic examination was limited due to cataracts. Ultrasound findings based on location and appearance during both static and dynamic evaluation that help differentiate a choroid vs. a retinal detachment are also described. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Choroid detachments have a different sonographic appearance, as well as management, compared to a retinal detachment.

Although colonoscopy is generally a safe procedure, lethal complications can occur. Colonoscopic perforation is one of the most serious complications, and it can present with various clinical symptoms and signs. Aggravating abdominal pain and free air on simple radiography are representative clinical manifestations of colonoscopic perforation. However, unusual symptoms and signs, such as dyspnea and subcutaneous emphysema, which are less likely to be related with complicating colonoscopy, may obscure correct clinical diagnosis. We present two cases of pneumomediastinum, pneumothorax, and subcutaneous emphysema caused by colonoscopic perforation. ⋯ A 75-year-old woman and a 65-year-old man presented with dyspnea, and facial swelling and abdominal pain, respectively. In the first case, symptoms occurred during polypectomy, whereas they occurred after polypectomy in the second case. Chest radiograph and computed tomography scans revealed pneumomediastinum, pneumothorax, and subcutaneous emphysema in the neck. During both operations, an ascending colonic subserosa filled with air bubbles was observed, and laparoscopic right hemicolectomy was performed in the first case. In the second case, after mobilization of the right colon, retroperitoneal colonic perforation was identified and primary repair was performed. The postoperative course was uneventful. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: These cases show the unusual clinical manifestations of colonoscopic perforation, which depend on the mechanism of perforation. Awareness of these less typical manifestations is crucial for prompt diagnosis and management for an emergency physician.

Despite being an effective analgesic for children with fractures, some clinicians may avoid prescribing ibuprofen due to its potentially harmful effect on bone healing. ⋯ Children with extremity fractures who are exposed to ibuprofen do not seem to be at increased risk for clinically important bone healing complications.

Syncope is a transient loss of consciousness that is caused by a brief loss in generalized cerebral blood flow. ⋯ The syncope work-up should be tailored to the patient's presentation. Disposition should be based on the results of the initial evaluation and risk factors for adverse outcomes.

Strychnine is a highly toxic alkaloid found in both naturally occurring compounds and commercial products. Extracts of fruits from the strychnine plant have been used in Southeast Asia as remedies for various illnesses. We describe strychnine poisoning from ingestion of a Southeast Asian herbal supplement quantitatively confirmed by serum and urine analysis. ⋯ A 40-year-old Cambodian woman presented to the emergency department with a complaint of jaw pain and spasms. The patient was staying with a relative and drank 2 oz from an unmarked bottle that she thought contained vodka. She then developed trismus and abdominal cramping, after which a family member said the bottle contained a compound called "slang nut." Her vital signs were as follows: heart rate 102 beats/min, blood pressure 142/72 mm Hg, respiratory rate 20 breaths/min, and oxygen level 100%. The physical examination revealed no significant abnormalities. Serum toxicologic screens were negative except for strychnine levels that revealed a serum concentration of 350 ng/mL and a urine concentration >200 ng/mL. The patient was observed for 2.5 h and discharged with no long-term complications. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Strychnine is a well-known compound that has been used in poisons, rodenticides, and performance enhancing drugs for years. In the Western world, strychnine is a much less common poisoning given that its use has been restricted because of the potential for severe toxicity; however, given its potentially high mortality, it is important to be aware of other sources of exposure, including those from herbal and homeopathic remedies.
