Otolaryngologic emergencies in the outpatient setting.

Disease processes involving the ear, nose, and throat account for millions of office visits to primary care physicians per year. Because of their proximity to the airway as well as critical neurologic and vascular structures, the disease process in each individual case carries the potential for significant complications. Fortunately, improvements in medical care have significantly reduced the prevalence of these complications. As a result of their relative rarity, most physicians may be unfamiliar with the clinical presentation of these entities. This article familiarizes the physician with the pathophysiology and clinical presentation of the more commonly encountered otolaryngologic complications. The physician should seek to rule out the presence of the aforementioned complications in each patient who presents with an otolaryngologic complaint. Any suggestion of their presence should prompt an immediate referral to a subspecialist or an emergency department. It is hoped that continued familiarization with these' disease processes will maintain them as rare entities of medical practice.

Pulmonary considerations in the immunocompromised patient.

The compromised patient who presents to the emergency department with pulmonary complaints is becoming a common occurrence. An immunocompromised state can result from a disease process such as HIV or from medications used to prevent graft rejection in solid organ recipients or to treat conditions such as collagen vascular disease. The emergency department physician should be familiar with the more common complications that can afflict this unique patient group. This article addresses the presentation, evaluation, and treatment of the more common pulmonary complications that can occur in solid organ transplant recipients, cancer patients, patients suffering from collagen vascular disease, and patients with HIV disease.
