Thyroid storm is an often-discussed but rare presentation to emergency departments (EDs). The clinical presentation of a thyroid storm is the result of a hyperthyroid state that may result in significant morbidity or disability, or even death. Typically, patients are aware of their hyperthyroid condition, and may be able to recognize an episode of thyroid storm. However, the first presentation of hyperthyroidism could, in fact, be from thyrotoxic crisis. ⋯ We use this case to emphasize that thyrotoxic crisis should be at least considered in the differential diagnosis of a patient with this presentation, and to highlight how, even with apparently usual and effective treatments, a patient may still decompensate.

Review Case Reports
Hypercapnic coma due to spontaneous pneumothorax: case report and review of the literature.
Hypercapnic coma is a rare differential diagnosis in the unconscious patient. One underlying mechanism may be hypoventilation due to spontaneous pneumothorax. Although hypercapnia is not a typical finding in spontaneous pneumothorax in patients with otherwise healthy lungs, under certain circumstances, hypercapnia may readily develop. ⋯ Although severe hypercapnia is usually due to decompensation of chronic lung disease, pneumothorax potentially may cause hypercapnic coma. Review of the literature suggests that there is no close correlation between arterial pCO(2) (partial pressure of CO(2)) levels and the degree of impairment of consciousness; however, levels exceeding 80 mm Hg are likely associated with significantly impaired consciousness. Hypercapnic coma usually resolves without neurological deficit as arterial pCO(2) tensions decline.

Pulmonary embolism (PE), an uncommon diagnosis in pediatric patients, is a potentially life-threatening condition with significant morbidity and mortality. Improvements in pediatric care have resulted in survival of more chronically and critically ill children and thus, an increased number of pediatric patients at risk for this disease. ⋯ Although there is a significant lack of pediatric-specific literature pertaining to the diagnosis and management of PE, there are clear differences in the emergency approach to these patients, including specific risk factors and the inutility of clinical decision rules and D-dimer. CONCLUSION/SUMMARY: We outline these differences and present rational diagnostic and treatment algorithms.
