Total anomalous pulmonary venous return (TAPVR) is an uncommon congenital heart defect. Obstructed forms are more severe, and typically present earlier in life, usually in the immediate newborn period, with symptoms of severe cyanosis and respiratory failure. ⋯ A 13-day-old boy presented to the emergency department (ED) with respiratory extremis. He appeared cyanotic and limp, and was found to have significant hypoxia with oxygen saturation of 40%. He had no improvement of oxygenation with bag-valve-mask ventilation despite a fraction of inspired oxygen near 100%. This gave clear indication that the hypoxia was caused by a shunt and not by hypoventilation, a ventilation/perfusion mismatch, or a barrier to diffusion. Next, the patient was intubated emergently. Broad spectrum antibiotics and fluid resuscitation with normal saline were initiated. A chest radiograph showed evidence of pulmonary edema vs. diffuse interstitial disease. Cardiology was consulted and evaluated the child with an echocardiogram, which revealed TAPVR with infradiaphragmatic obstructed veins. Once stabilized, he was transferred for definitive surgical repair. This is, to our knowledge, the first reported case of TAPVR with infradiaphragmatic obstruction presenting to the ED with hemodynamic and respiratory compromise beyond the first week of life. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Despite improvements in antenatal and newborn screening, congenital heart disease often remains an elusive diagnosis. Some patients with these critical lesions are discharged home before the manifestation of their disease becomes apparent. Once symptomatic, these patients often present to the ED in extremis. We conclude that it is important to recognize this presentation to ensure proper evaluation and early diagnosis. If misdiagnosed, many of the usual therapies for other diseases could be detrimental.

Acute flaccid myelitis (AFM) is increasing in incidence in the United States and presenting to emergency departments (EDs) across the country. This clinical entity presents as acute paralysis, with magnetic resonance imaging changes in the gray matter only in children younger than 21 years of age. The etiology is unknown, although preceding viral illnesses are common. There are no consensus guidelines regarding treatment. ⋯ A 4-month-old girl presented with decreased bilateral arm movement. The history consisted of a recent upper respiratory illness and abrupt decline in movement. She was found to have truncal and peripheral hypotonia, while maintaining her airway. Magnetic resonance imaging found gray matter hyperintensity at C2-C6, with no white matter changes. The patient was positive for enterovirus. Intravenous steroids and intravenous immunoglobulin were given, with slight improvement prior to discharge to an inpatient rehabilitation center. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: AFM was largely nonexistent in the United States after implementation of the polio vaccine, but the incidence has recently increased. Pediatric patients are now presenting to EDs with acute hypotonia, and emergency physicians must recognize how to differentiate this emerging diagnosis from other causes of acute flaccid paralysis. The clinical course of AFM does not seem to change acutely, in stark contrast to disease entities like botulism, which can change in hours. Patients with AFM do not need aggressive ED diagnostic evaluation, but rather transfer to a pediatric hospital for further care. Therefore, discerning the etiology of pediatric hypotonia with history and physical examination alone is important.

Sudden cardiac arrest accounts for approximately 15% of deaths in developed nations, with poor survival rate. The American Heart Association states that epinephrine is reasonable for patients with cardiac arrest, though the literature behind its use is not strong. ⋯ Epinephrine may improve return of spontaneous circulation, but it does not improve survival to discharge or neurologic outcome. Timing of epinephrine may affect patient outcome, but Basic Life Support measures are the most important aspect of resuscitation and patient survival.

Osteochondroma is the most common benign tumor of the bone. It is usually asymptomatic, but complications may result from mechanical injury to adjacent anatomic structures, such as the diaphragm and lung, when located intrathoracically. ⋯ We report the unusual occurrence of a large hemothorax and lacerated right diaphragm in a 41-year-old woman caused by vertebral osteochondroma affecting the eleventh thoracic vertebra. Thoracoscopic exploration with resection of the osteochondroma and repair of the diaphragm was performed. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Spontaneous hemothorax is a potential life-threatening condition when the initial diagnosis is postponed and hemodynamic instability and hypovolemic shock occurs. Osteochondroma as a cause of spontaneous hemothorax is uncommon but may require urgent surgical intervention with video-assisted thoracoscopic surgery of thoracotomy to control the hemorrhage and prevent recurrence.
