Sudden sensorineural hearing loss (SSNHL) presents as an abrupt onset of hearing loss; 88% of these presentations are idiopathic (ISSHL). Many mechanisms of injury and etiopathologies have been postulated, but they share a common result - hypoxia of the organ of Corti leading to hair cell-cilia fusion, synaptic, dendritic swelling and sustained depolarization. Of all of the various treatments tried, only corticosteroids and hyperbaric oxygen (HBO2) therapy have shown benefit in randomized contro...

Dermatologic conditions are usually nonemergent but occasionally represent a life-threatening condition. This chapter presents an algorithmic approach to the ED patient with a rash. A set of four algorithms are presented dividing rashes into diffuse erythema, maculopapular, vesiculobullous, and petechial or purpuric. For each category, the key distinguishing features are included that help differentiate the common from life-threatening conditions.

Hyperbaric oxygen therapy (HBOT) can be a useful primary or adjunctive therapy for a variety of medical disorders, many of which involve the eye. This chapter will review the effects of oxygen on eye, the literature describing use of HBOT for a variety of conditions and the potential complications of HBOT affecting the eye. The authors recommend the following as ocular indications for HBOT: decompression sickness or arterial gas embolism (AGE) with visual signs or symptoms, central retinal arter...
