The differential diagnosis of stridor in the pediatric population is broad and should include hypocalcemia with resultant laryngospasm. We present the case of a breast-fed infant who presented to the pediatric emergency department with profound stridor during the winter months because of hypocalcemia of undiagnosed rickets. The patient responded to intravenous calcium chloride with rapid resolution of symptoms. Emergency physicians should consider obtaining ionized calcium levels in pediatric patients with stridor, especially when standard therapies for more common causes of stridor are ineffective.

Tension hydrothorax is rare, with few cases reported in the literature dating back to the late 1960s. We report a case of tension hydrothorax in a patient with a ventriculopleural shunt who improved dramatically after thoracentesis. The discussion includes a brief review of ventriculopleural shunts and pleural physiology.

Clinical infections of Vibrio vulnificus: a case report and review of the literature.
Vibrio vulnificus is a marine Gram-negative bacillus that is recognized as a cause of fulminant primary septicemia and wound infections. One of the most common bacteria in seawater, V. vulnificus is concentrated in ocean filter feeders (e.g., oysters and clams). Primary septicemia can occur in patients, typically with underlying liver disease, who have acquired the organism through the gastrointestinal tract after recent consumption of raw shellfish. ⋯ Wound infections are seen after injury to the skin in a marine environment or from exposure of preexisting wounds to seawater. Because of the high morbidity and mortality associated with V. vulnificus infections, effective treatment includes preventive measures to educate high-risk individuals, early search for and recognition of the disease, aggressive antibiotic therapy, supportive care, and, in the case of wound infections, aggressive debridement. Review of this subject was prompted by a case of V. vulnificus primary septicemia and fulminant septic shock in a patient with the unusual presentation of pain in the lower extremities.

Pulmonary embolism presenting as an isolated syncopal spell can be a difficult clinical correlation to make. We present three cases of pulmonary embolism-induced syncope and review the pathophysiology and diagnostic considerations in this setting. Pulmonary embolism should be considered in the differential diagnosis of every syncopal event that presents to the emergency department, even in the face of cardiac dysrhythmias and normal pulse oximetry values.

Currently, there are no data that govern the number of procedures that are necessary to promote competence during emergency medicine (EM) training. Nonetheless, the Residency Review Committee requires each program to report the average number of procedures and resuscitations performed by its residents. For 7 years, we have used a computer database to track resuscitation and procedure experience for 42 residents. ⋯ There is no documentation that some residents perform even one of some rare but critical procedures. This tracking system suggests, then, that procedure simulations, or cadaver and animal models, must be developed and used to enhance experience. This program can be modified to track resident experience in any specialty, as well as to document supervision by faculty and support credentialling inquiries.
