Acute cholecystitis in the emergency department.

Acute cholecystitis is a frequent consideration in patients presenting to the emergency department with the challenging complaint of upper abdominal pain. It is estimated that 20% of American adults have gallstones, and of these a large percentage (about one-third) will at some point develop acute cholecystitis. The epidemiology and associated risk factors of acute cholecystitis are briefly reviewed along with the pathogenesis and clinical presentation of the disease. Finally, an approach to the diagnosis in the emergency department and suggested management is discussed including a comparison of the strengths and weaknesses of ultrasonography and hepatobilary scintigraphy.

Arterial injury from a high pressure water jet: case report.

We report the case of a patient who sustained a high-pressure water jet injury to the thigh while cleaning industrial piping. The patient presented with a puncture wound to the anterior thigh and a pulseless foot. Emergency arteriography was performed that revealed complete disruption of the superficial femoral artery. The patient underwent surgical exploration and debridement, and a successful repair of the disrupted artery was performed with a prosthetic arterial graft. A discussion of high-pressure water jet injuries and their management is presented.

Deep venous thrombosis of the upper extremity: diagnosis and treatment.

Deep vein thrombosis of the upper extremity was long thought to be a benign disease, rarely complicated by pulmonary embolism and associated with minimal long-term morbidity. More recent observations have demonstrated however, that a significant number of patients will continue to have disabling symptoms after treatment with conservative measures and standard anticoagulation therapy, and that pulmonary embolism can occur in the course of the disease. Because of its significant morbidity and increasing incidence, an aggressive emergency department approach to diagnosis and early consideration of fibrinolytic therapy are recommended.

Raynaud's phenomenon in the emergency department.

Raynaud's phenomenon manifests as triphasic color changes of the digits, induced by exposure to low temperature or emotional stress. It is a relatively common disorder, estimated to affect 5% to 10% of the general population and 25% to 30% of otherwise healthy women. Although usually self-limiting, it can be severely painful and debilitating, and complicated by ulcerations and tissue necrosis. For the emergency physician treating a patient with an acute presentation of the phenomenon, the main challenges are to achieve adequate pain control, reverse vasospasm, and maintain viable tissue. Emergency treatment can also extend to patient education and arrangement of appropriate referrals and follow-up care.

Secondary acute angle closure glaucoma: a complication of AIDS.

A 58-year-old man with advanced AIDS presented to the emergency department complaining of headache and decreased vision bilaterally. On evaluation, he was found to have intraocular pressures of 69 and 65 mm Hg. After topical treatment with miotics and apraclonidine, he was given intravenous acetazolamide (Diamox) and peripheral iridotomy was performed. The pressures did not improve significantly. Secondary acute angle closure glaucoma was diagnosed. Emergency physicians should consider this diagnosis when evaluating AIDS patients with visual complaints.

Cerebral ventricular shunts.

Cerebral ventricular shunts are siphoning devices used to treat hydrocephalus. They are placed within cerebral ventricles and peripheral cavities such as the ventricular atrium or peritoneal cavity. Complications include obstruction of cerebral spinal fluid (malfunction) and infection. Morbidity and mortality rates are high when shunt malfunction and infection are not treated emergently. This report summarizes the physical examination of patients with ventricular shunts, reviews the type of shunts commonly used, discusses shunt malfunctions (causing overshunting or undershunting of cerebrospinal fluid) and infections, and makes recommendations concerning empiric antibiotic therapy for shunt infection. The technique of tapping a shunt is presented for management of patients with elevated intracranial pressure that does not respond to non-invasive maneuvers to lower the pressure.

Reengineering the emergency evaluation of chest pain.

This article presents strategies for enhancing the emergency department care delivered to patients with chest pain and suspected acute myocardial infarction. It also describes the planning and implementation of an emergency department reengineering project at a university medical center. The establishment of chest pain evaluation centers within emergency departments has been associated with improved clinical outcomes and cost control. Creating such a center requires careful revamping of diagnostic and treatment algorithms, a process that must be based on information from all departments affected by the changes.
