Prochlorperazine maleate versus placebo for the prevention of acute mountain sickness: study protocol for a randomized controlled trial.

Background: Acute mountain sickness (AMS) is a debilitating condition that individuals may develop on ascent to high altitude. It is characterized by headache, nausea, vomiting, dizziness, and fatigue with the potential to progress to fatal disease. Although the pathophysiology of AMS remains unclear, proposed mechanisms are hypothesized to be similar to migraine.

Mode of transportation of out-of-hospital cardiac arrest patients, the role of community actions and interventions.

The Emergency Medical Services constitutes a critical component in treating patients with out-of-hospital cardiac arrest (OHCA). Activating the EMS system is the first important step in deploying resources, but community involvement in the care of emergent patients is multifaceted and complex. How does the public access EMS services versus other modes of transport remains under investigated; and if the public opts for a different mode of transport to the hospital, how does this affect outcomes?

Wilderness Medical Society Clinical Practice Guidelines on Anaphylaxis.

The Wilderness Medical Society convened a panel to review the literature and develop evidence-based clinical practice guidelines on the treatment of anaphylaxis, with an emphasis on a field-based perspective. The review also included literature regarding the definition, epidemiology, clinical manifestations, and prevention of anaphylaxis. The increasing prevalence of food allergies in the United States raises concern for a corresponding rise in the incidence of anaphylaxis.

Epidemiology of Ice Climbing Injuries Among Recreational Ice Climbers at the 2019 Ouray Ice Climbing Festival.

Introduction: As a close relative to the sports of mountaineering and rock climbing, water ice climbing has been traditionally considered "high risk." There is little data to support or refute this assertion. Prior estimates of the injury rate range from 4.

Clinical staging of accidental hypothermia: The Revised Swiss System: Recommendation of the International Commission for Mountain Emergency Medicine (ICAR MedCom).

Clinical staging of accidental hypothermia is used to guide out-of-hospital treatment and transport decisions. Most clinical systems utilize core temperature, by measurement or estimation, to stage hypothermia, despite the challenge of obtaining accurate field measurements. Recent studies have demonstrated that field estimation of core temperature is imprecise.

Effort Thrombosis Presenting as Unilateral "Pumped" Arm in a Climber.

Upper extremity injuries are common among the growing population of climbers. Although conditions affecting musculoskeletal structures are the most common causes of symptoms, a comprehensive differential diagnosis is necessary to avoid the misdiagnosis of high-morbidity conditions in this patient population. We present a case of a climber with acute edema, erythema, and pain of the entire right upper extremity.

Subarachnoid Mirage: A Case of Pseudosubarachnoid Hemorrhage.

A 22-year-old man with a history of intravenous methamphetamine use presented with severe headache for 5 days, was afebrile, and had nuchal rigidity. Computed tomography and magnetic resonance imaging results were interpreted as revealing acute subarachnoid hemorrhage. Twenty-four hours later, he developed acute neurologic deterioration.

[Limitation of life-sustaining treatment. A prospective study in a clinical ward].

The purpose of this study is to describe the limiting life-sustaining treatment process of patients admitted to a general ward. A prospective descriptive study was designed. The setting was the general ward of universitary hospital.
