INTRODUCTION: Avalanche risk can be mitigated by adhering to certain safety practices. Previous studies of these practices have focused on western United States and European cohorts. We conducted a survey of backcountry users in the White Mountains of New Hampshire to determine local adherence to 5 previously studied avalanche safety practices. We assessed whether participants were carrying transceiver, probe, and shovel (TPS); had formal avalanche education; had awareness of the day's avalanche danger level; had a route plan; and were traveling in a group...

Reports of paedoptera dermatitis are commonly found in tropical and subtropical regions, while reports in China are rare. In September 2022, an outbreak of paedoptera dermatitis occurred in a minority autonomous county in southwestern China. Here, we report 134 patients with paedoptera dermatitis who were treated at the People's Hospital of Sandu Shui Autonomous County. The skin lesions of these patients were mostly located on the face, neck, trunk, or multiple sites. The skin lesions were mainly distributed in patches and were characterized by vesicular linear or "kissing" lesions...

INTRODUCTION: Casualties with accidental hypothermia are evacuated using multilayer wraps, typically including a chemical heat blanket (CHB), a vapor barrier, and an insulating outer bag. We investigated CHB performance against dry, damp, and wet fabric, in a multilayer wrap, in response to a case report indicating diminished performance when wet. METHODS: We wrapped a torso manikin in a base layer, CHB, vapor barrier, casualty bag, and vacuum mattress, recording CHB panel temperatures at intervals of up to 7 h...

Psychotic symptoms can occur at high altitude. However, most reports are in the mountaineering literature and lack a clear medical assessment and interpretation. Here we report an episode of isolated high-altitude psychosis. It consisted of a "third person" phenomenon involving 2 sensory modalities: somesthetic (felt presence) and visual (the light of 2 flashlights) hallucinations. This episode occurred in a highly experienced climber when he was at an altitude of approximately 7500 m while descending at dusk from the summit of Gasherbrum I (8068 m)...

Microscopic polyangiitis is an important and common component of cytoplasmic antibody-associated vasculitides that can lead to serious morbidity and even death. A clear causative etiology has not been identified. Although silica is well known to produce lung damage, the negative renal effects of silica exposure should not be overlooked. We present a case of renal dysfunction associated with silica exposure, its diagnosis by renal biopsy, and the treatment method used. Environmental or occupational silica exposure can cause microscopic polyangiitis...

Long-distance "thru-hiking" has extraordinary physical demands and has become increasingly popular. This report describes a man (55 y) who thru-hiked the Pacific Crest Trail in 2021 and was at risk of developing the relative energy deficiency in sport (RED-S) syndrome. Hiking distance was 3767 km over 128 d. Eighty-eight days (69%) were full days of hiking, covering 38±8 km/d (mean±SD) in 7.9±1.6 h/d. Exercise energy expenditure above rest (heart rate vs indirect calorimetry regression method) was 2834±1518 kcal/d, total energy expenditure was 5702±1323 kcal/d, and energy intake was 4141 kcal/d...

INTRODUCTION: The importance of providing wet bulb globe temperature (WBGT) heat stress flag category measurements in real time is well recognized by road race directors, and it is bound to become even more important with the rise of extreme weather and pandemic outbreaks. The purpose of this paper is to describe the WBGT index and its components measured during the 125th running of the Boston Marathon on October 11, 2021, for qualitative comparison to measurements made similarly on its traditional April date, 2014 to 2019...

INTRODUCTION: We aim to provide better insights into the demographic, epidemiological, and seasonal characteristics of scorpion envenomation reported in the Rio Doce Valley, Brazil. METHODS: We conducted this monocentric retrospective descriptive study with data on Investigation Forms of Accidents by Venomous Animals, only envenoming cases of scorpion stings, between January 1, 2017 and December 31, 2020, belonging to the compulsory notification system of the Municipal Hospital of Governador Valadares...

INTRODUCTION: The aim of this study was to evaluate different grip positions as a contributing factor for primary periphyseal stress injuries of the finger phalanges in climbing. METHODS: Ultrasound imaging of the proximal interphalangeal joint was performed on 37 asymptomatic adolescent climbers. Longitudinal images were obtained of middle and ring fingers of both hands in different grip positions (open, half-open, and crimp), unloaded and loaded. The translation between the dorsal head of the proximal phalanx and the shaft of the middle phalanx was measured in an unloaded and loaded situation for all grip positions...

INTRODUCTION: The dermatological effects of box jellyfish envenomation among stinging victims in Thailand are not well reported, particularly concerning chronic effects. For first aid, different recommendations indicate the necessity for the removal of tentacles in life-threatening situations. This study aimed to describe the dermatological effects of box jellyfish envenomation and propose recommendations regarding first aid for victims in urgent care or life-threatening situations. METHODS: Surveillance systems and Toxic Jellyfish Networks were established to improve detection and investigation...

INTRODUCTION: Strength training has proved to be an effective way to prevent injuries, but the evidence of the impact of strength training on finger injuries is lacking. A fingerboard is a sport-specific tool used by climbers for strength training of fingers. In this study, we searched for associations between fingerboard training and finger injuries in climbers with different lengths of climbing experience and levels of performance. METHODS: A web-based survey was used to collect information on self-perceived pain or injury in fingers (SPIIF) and regular fingerboard training (RFT)...

INTRODUCTION: The Canadian Frostbite Collaborative project is exploring frostbite patient care needs and current practices in Canada to inform the development of a Canadian frostbite care network (CFCN) as a national quality improvement initiative. METHODS: Using a quantitative and qualitative approach, this study aimed to define the landscape of current frostbite practices, challenges, and interest in future work. RESULTS: Current frostbite care practices were initially assessed through semistructured phone interviews of Canadian healthcare providers...

INTRODUCTION: Compartment syndrome (CS) is a rare but serious complication after crotalid envenomation in the United States. Few data are available regarding the epidemiology and management of these cases. Significant controversy and misunderstanding over best practices, including measurement of compartment pressures and use of fasciotomy, exist for this syndrome. This study aims to describe presentation and management of suspected CS cases after native snakebite reported to the North American Snakebite Registry (NASBR)...
