Review Case Reports
Soft tissue injection of hydrocarbons: a case report and review of the literature.
Hydrocarbon injection, while commonly seen in domestic accidents or attempted suicide, is not extensively addressed in the literature. This article comprises a review of the various complications of intravascular and soft tissue injection of petroleum distillates, and provides recommendations for patient management. An illustrative case involving the subcutaneous injection of dripless oil, a mixture of mineral oil, nonionic detergents, and petroleum naphtha, is presented.

Randomized Controlled Trial Comparative Study Clinical Trial
Cricothyrotomy technique: standard versus the Rapid Four-Step Technique.
Standard cricothyrotomy technique uses a tracheal hook cephalad to the opening to stabilize the trachea during endotracheal (ET) tube passage. A newly described Rapid Four-Step Technique (RFST) uses the tracheal hook caudal to the opening to stabilize the trachea during ET tube passage. This experimental crossover trial compared standard cephalad tracheal hook traction to caudad traction as recommended by RFST in a cadaver model of cricothyrotomy. ⋯ There was no significant difference between maximal ET tube sizes for standard technique (median size 7.0, mean 6.95 mm internal diameter) versus RFST (median size 7.0, mean 6.82 mm internal diameter). We conclude that RFST may be associated with a higher incidence of complications than standard technique as demonstrated by our cadaver model of cricothyrotomy. We were unable to demonstrate a difference between the two techniques with regards to size of ET tube able to be passed.

Carbon monoxide (CO) poisoning continues to be a significant health problem both in the United States and in many other countries. CO poisoning is associated with a high incidence of severe morbidity and mortality. Epidemics of CO poisoning commonly occur during winter months and sources include: smoke from fires, fumes from heating systems burning fuels, and exhaust fumes from motor vehicles. ⋯ The clinical presentation is non-specific and may range from nausea and headache to profound central nervous system dysfunction. The mainstay of therapy for CO poisoning is supplemental oxygen, ventilatory support, and monitoring for cardiac dysrhythmias. This article reviews up-to-date information of this potentially devastating exposure.

Oral ingestion of baking soda (sodium bicarbonate) has been used for decades as a home remedy for acid indigestion. Excessive bicarbonate ingestion places patients at risk for a variety of metabolic derangements including metabolic alkalosis, hypokalemia, hypernatremia, and even hypoxia. ⋯ We present two cases of severe metabolic alkalosis in patients with unsuspected antacid overdose. The presentation and pathophysiology of antacid-related metabolic alkalosis is reviewed.

Thyrotoxic periodic paralysis is a rare endocrine disorder most prevalent among individuals of Asian descent that presents as proximal muscle weakness, hypokalemia, and signs of hyperthyroidism. We present the case report of a patient with previously undiagnosed hyperthyroidism, protracted muscle weakness with transient exacerbations, and nocturnal onset of periodic paralysis affecting the upper and lower limbs.
