Case Reports
Morel-Lavallée Lesion Diagnosed by Point-of-Care Ultrasound: A Case Report and Review of Treatment Strategies.
Morel-Lavallée lesions, also known as an internal degloving injuries, occur hours to months after high-speed shearing trauma, usually in the peri-trochanteric region. These are uncommon injuries, and are often missed as part of the trauma examination. Failure to diagnose or treat these lesions may result in complications, such as infected seromas, chronic cosmetic deformities, capsule formation, or skin necrosis. There are no formalized societal guidelines for management, but smaller studies have recommended compression alone for asymptomatic lesions, aspiration for small symptomatic lesions, and open debridement for large lesions. ⋯ A young woman presented with swelling, fluctuance, and paresthesia to her right hip after falling off her bicycle 1 week earlier. Physical examination showed a fluctuant and hypoesthetic area over the greater trochanter and point-of-care ultrasound showed a hypoechoic and compressible fluid collection between a fascial layer and a subcutaneous layer, confirming the diagnosis of a Morel-Lavallée lesion (internal degloving injury). Symptoms did not improve with compression alone, but did improve after fluid aspiration. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Morel-Lavallée lesions are frequently missed traumatic injuries. Morel-Lavallée lesions can be diagnosed quickly and cost-effectively in the emergency department through the combination of a thorough history, physical examination, and bedside ultrasound. Although there are no formal societal guidelines, limited studies suggest management strategies, including compression, aspiration, and open debridement, with treatments varying by symptom severity and lesion size.

Randomized Controlled Trial
Is Lateral Decubitus or Upright Positioning Optimal for Lumbar Puncture Success in a Teaching Hospital?
Lumbar puncture is a common procedure performed by emergency physicians and trainees. The optimal patient positioning for lumbar puncture procedures has not been studied adequately. ⋯ Lateral decubitus and upright positioning for emergency lumbar puncture yielded equal success rates in emergency physicians and trainees.

Trauma patients present to the emergency department with various injuries. Few injuries can be easily missed during the evaluation of polytrauma patients. We report one such rare injury in a trauma patient. ⋯ We report the case of a 67-year-old man who presented to the emergency department with an alleged history of trauma. He reported severe pain in the lower abdomen, right hip, and right thigh. An x-ray study did not reveal any bony injury, and an extended focused assessment with sonography in trauma was also negative. Point-of-care ultrasound of his right thigh revealed the presence of a Morel-Lavallée lesion. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Morel-Lavallée lesions are post-traumatic, closed, degloving injuries that go unnoticed in many polytrauma patients. Emergency physicians should be mindful of this lesion because delay in diagnosis can result in significant complications.

Chemotherapy-induced febrile neutropenia (FN) is one of the more common oncological emergencies. Despite evidence in the oncology literature suggesting that low-risk cases of FN can be managed safely at home, most patients with FN who present to the emergency department (ED) are admitted. FN risk stratification methods, such as Multinational Association for Supportive Care in Cancer (MASCC) and Clinical Index of Stable Febrile Neutropenia (CISNE) scores, may be useful when considering patient disposition. We sought to address whether the existing body of literature is adequate to support the use of these methods when treating patients with FN in the ED. ⋯ FN risk stratifications tools, such as MASCC and CISNE scores, are supported by the existing literature and may be included as part of the decision-making process when considering patient disposition.

Refocused national HIV testing initiatives include a geographic focus. ⋯ EDs in priority counties affiliated with teaching hospitals are major sources of health care in California. These EDs more often serve populations disproportionately impacted by HIV. These departments are efficient targets to direct testing efforts. Increasing testing in these EDs could reduce the burden of undiagnosed HIV in California.
