Review Case ReportsAirway compromise after first rattlesnake envenomation.
The purpose of this report is to describe an unusual presentation of anaphylaxis after first-time rattlesnake envenomation. A patient on a medical toxicology inpatient service is presented who had signs of anaphylaxis, including airway compromise, after first-time rattlesnake envenomation. ⋯ The patient's recovery was prolonged. In conclusion, rattlesnake envenomation may result in rapidly progressive airway compromise, possibly caused by anaphylaxis in patients with previous dermal or gastrointestinal exposure to snake proteins.

Epidemiology of wilderness search and rescue in New Hampshire, 1999-2001.
To describe the epidemiology of wilderness search and rescue in a region with easily accessible, heavily used wilderness areas. ⋯ The most prevalent demographic group requiring search-and-rescue efforts in New Hampshire was men aged 30 to 40 years who were hiking and who resided within a 4-hour drive of the area where they encountered difficulty. To decrease the number of people involved in most search and rescue, efforts should be focused on preventing wilderness users from getting lost and preventing lower extremity musculoskeletal injuries. Wilderness deaths may be prevented by focusing attention on cardiac health in wilderness users older than 50 years and on water safety.

Biography Historical Article Classical ArticleThe immersion foot syndrome. 1946.
1. Prolonged exposure of the extremities to cold insufficient to cause tissue freezing produces a well-defined syndrome. 'Immersion foot' is one of the descriptive but inaccurate terms applied to this syndrome. The clinical features, aetiology, pathology, prevention, and treatment of immersion foot are considered in detail. ⋯ During the period of the study, one of us (R. L. R.) was in receipt of a personal grant from the Medical Research Council.

Randomized Controlled Trial Clinical TrialLack of effect of Rhodiola or oxygenated water supplementation on hypoxemia and oxidative stress.
This study investigated the effects of 2 potentially "oxygen promoting" dietary supplements on hypoxia and oxidative stress at a simulated altitude of 4600 m. ⋯ The 2 dietary supplements investigated did not have a significant effect on blood oxygenation after 60 minutes of sedentary hypoxic exposure. Hypoxia-induced oxidative stress was observed in the control group only. Both supplements appeared not to increase oxidative stress and may decrease free radical formation after hypoxic exposure compared with the control.
