The Effects of Acetazolamide on Exercise Performance at Sea Level and in Hypoxic Environments: A Review.

Lowlanders rapidly ascending to high altitude (>2500 m) often develop acute mountain sickness (AMS). While acclimatization is the most effective method of reducing symptoms of AMS (ie, headache, fatigue, nausea, gastrointestinal distress, etc.), it may take several days to become fully acclimated.

Enhancement of Cricothyroidotomy Education Using a Novel Technique: Cadaver Autografting.

Background: Cricothyroidotomy is a lifesaving procedure required in up to 2% of emergent airways. Emergency medicine training programs frequently instruct this procedure via cadaver training, but cadaver cost and availability limit the opportunity for all trainees to perform the critical initial skin incision. Cadaver autografting is a novel way to simulate all steps of the procedure.

Is point-of-care ultrasound accurate and useful in the hands of military medical technicians? A review of the literature.

Over the past decade, point-of-care ultrasound (US) use by nonphysician providers has grown substantially. The purpose of this article is to (1) summarize the literature evaluating military medics' facility at US, (2) more clearly define the potential utility of military prehospital US technology, and (3) lay a pathway for future research of military prehospital US. The authors performed a keyword search using multiple search engines.

A blinded, randomized, palatability study comparing variations of 2 popular field water disinfection tablets.

Objective: Halogen-based water disinfection tablets may render an unpleasant taste to treated water. Proposed safe additives such as ascorbic acid may reduce this objectionable taste. We compared the palatability of 2 field water disinfectants: iodine-based tetraglycine hydroperiodide (TGHP) and chlorine-based chlorine dioxide (CD) both with and without the concomitant use of an ascorbic acid taste neutralizer.

10% Povidone-iodine may be a practical field water disinfectant.

Objective: A paucity of data exists regarding the use of iodophores such as povidone-iodine (PVI) to disinfect water. We sought to determine a practical minimal disinfecting concentration of 10% PVI over different contact times and temperatures when added to water inoculated with E. coli.

Lemierre syndrome complicating otitis externa: case report and literature review.

Background: Septic thrombophlebitis of the internal jugular vein, known as Lemierre syndrome, is a rare disorder usually caused by Fusobacterium necrophorum, a Gram-negative anaerobic organism that normally inhabits the oropharynx. Lemierre syndrome usually follows primary oropharyngeal infections and affects previously healthy adolescents and young adults in a characteristic manner, often with fatal results if left untreated. There have been a significantly increasing number of reported cases of Lemierre syndrome, possibly reflecting the trend to withhold antibiotics for initially uncomplicated oropharyngeal infections.

Emergency department presentation of a rare neurological disorder.

The treatment and disposition of patients with neurological disorders is commonplace in the emergency setting, but atypical and uncommon presentations can prove to be especially challenging. In this article we discuss the case of a 31-year-old woman who presented with a rare disorder known as opsoclonus myoclonus syndrome (OMS). OMS is characterized by involuntary, multidirectional movement of the eyes, myoclonus, and truncal ataxia.

A prospective analysis of the treatment of friction blisters with 2-octylcyanoacrylate.

Early military investigations of blister treatment using tissue adhesives have shown promise, finding that these agents provide pain relief, prevent infection, and allow continuation of recruit training. A trial was conducted to compare a 2-octylcyanoacrylate treatment with military standard therapy. Patients were recruited during foot evaluation at the end of a 10-km military road march.

Treatment of imported fire ant stings with mitigator sting and bite treatment--a randomized control study.

Objective: To evaluate the efficacy of the commercially available product Mitigator Sting and Bite Treatment in reducing the pain after imported fire ant stings.

Methods: Twenty-four volunteer subjects were exposed to imported fire ant stings on both fore-arms. The subjects received Mitigator paste on 1 arm and calamine lotion on the opposite arm, in a blinded manner, from 90 seconds to 10 minutes after exposure.
