It's Not Cyclic Vomiting Syndrome Until Dietl's is Ruled Out: A Case for Point of Care Renal Ultrasound.
Abdominal pain and vomiting are frequent complaints for pediatric patients presenting to the Emergency Department (ED). When a diagnosis such as chronic abdominal pain, cyclic vomiting, or abdominal migraine has previously been made, it can lead to diagnostic momentum and confirmation bias on behalf of the treating physician. Dietl's crisis is a commonly missed diagnosis in the pediatric population that presents with intermittent episodes of pain and vomiting. It can be readily diagnosed at the bedside by the emergency physician (EP) through the employment of point of care ultrasound (POCUS). ⋯ We present two cases of pediatric patients with episodic abdominal pain and vomiting who were previously diagnosed with cyclic vomiting syndrome. In both cases, pediatric gastroenterology evaluations had occurred with negative diagnostic testing having been performed. Both patients also presented to their primary pediatrician and the ED multiple times with each encounter resulting in treatment of symptoms and discharge. Each patient eventually presented to the ED when an EP was present who performed a renal POCUS. In each patient, the POCUS revealed severe unilateral hydronephrosis. Subsequent workup confirmed the diagnosis of Dietl's crisis as the etiology of symptoms. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: In pediatric patients, EPs should be wary of the diagnosis of cyclic vomiting syndrome until ureteral obstruction has been ruled out. A bedside POCUS can rapidly establish this diagnosis and potentially preclude recurrent health care visits, unnecessary diagnostic testing, and permanent loss of renal function.

Case Reports
Delayed Diagnosis of Labial Hair Thread Tourniquet Syndrome in a Postmenarchal Adolescent: A Case Report.
Hair thread tourniquet syndrome occurs when tissue is strangulated by a hair thread. It occurs most commonly in the digits of infants and young children, but can also occur in the genitalia. ⋯ A 13-year-old postmenarchal girl with several days of severe vulvar pain and swelling presented to the emergency department. Diagnosis was unclear and she was referred to pediatric and adolescent gynecology. Pelvic examination under anesthesia revealed a hair thread tourniquet involving the bilateral labia minora. The hair tourniquet and portions of bilateral labia minora were excised. Why Should an Emergency Physician Be Aware of This? Genital hair thread tourniquet syndrome is uncommon but must be considered in patients with severe genital pain and swelling. Prompt diagnosis and treatment are important to prevent tissue necrosis and may be facilitated by means of a pelvic examination with sedation.

Case Reports
A Rare Case of an Adult with Spinal Cord Injury Without Neuroimaging Abnormality (SCIWONA).
Spinal cord injury without radiographic abnormality (SCIWORA) is defined as having clinical symptoms of traumatic myelopathy with no radiographic or computed tomographic features of spinal fracture or instability. An abnormal finding, such as a fracture, subluxation, or abnormal intersegmental motion at the level of the spinal cord injury, excludes SCIWORA as the diagnosis. Prevalence of SCIWORA is highest among children younger than 8 years, and is a diagnosis seen primarily in children, owing to anatomic differences that put children at more risk of this condition. In more recent years, with the increasing use of magnetic resonance imaging in patients with suspected spinal cord injury, a new term, spinal cord injury without neuroimaging abnormality (SCIWONA) has been suggested as a more specific way to describe cases of SCIWORA that have negative neuroimaging. ⋯ Here we describe a case of a woman who presented with symptoms consistent with a spinal cord injury after a traumatic fall. Her presentation and imaging were consistent with SCIWONA. The patient subsequently had rapid and complete recovery of her neurologic function. Why Should an Emergency Physician Be Aware of This? Early recognition of SCIWONA and subsequent medical management is imperative for improved outcomes for these patients. Operative treatment is rare and typically only necessary in patients with consistent spinal cord instability.
