In many respects, this climb defined Hornbein (1930-2023) in the eyes of the international mountaineering community. One aspect of his career in high altitude mountaineering that also reflected his professional interests has received scant attention. This largely overlooked contribution was that of the design and development, in the years and months leading up to the American expedition to Everest, of a more capable and comfortable mask for use with an open-circuit supplemental oxygen system.

This study aimed to characterize injuries sustained in the BWCA.MethodsA single reviewer completed a retrospective chart review of trauma admissions to Essentia Health from January 1, 2014 to February 25, 2023. Patients were included if their injury was documented to have occurred in the BWCA and they had not opted out of research.ResultsEighteen patients were found to have sustained injury in the BWCA. Most were adult males (78%), White (89%), and nonsmokers (94%). Most patients had no alcohol (83.3%) or drug (94.4%) use related to the injury. Seven patients self-extricated out to the BWCA, 6 were transported by ground Emergency Medical Services, and 5 required flight extrication. Median time from notification of injury to Emergency Medical Services arrival was 64 min. Time from notification of injury to hospital arrival was a median of 131 min. Falls were the main mechanism of injury (61%), followed by strike injury (22%) and water injury (17%). A few patients required lifesaving interventions (eg, prehospital intubations, needle thoracostomy, and blood transfusion). Twelve patients required a procedure (eg, <5 chest tubes and 10 surgeries). All 18 patients were alive at discharge.ConclusionThe most common injuries sustained in the BWCA were from falls, strikes, and water injuries. In collaboration with forest ranger stations, we plan to provide this information to backpackers to assist in their preparation for backcountry emergencies.</p>","PeriodicalId":49360,"journal":{"name":"Wilderness & Environmental Medicine","volume":" ","pages":"10806032251351842"},"PeriodicalIF":1.4,"publicationDate":"2025-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144530687","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The patient presented to the emergency department with a laceration caused by a wild boar attack while hunting. Initial assessment revealed a deep laceration over his anterior knee and radiographs demonstrated significant air within the knee joint, consistent with a traumatic knee arthrotomy. The patient was placed on empiric, broad-spectrum antibiotics and underwent urgent surgical irrigation and debridement. Intraoperative cultures were sent, and infectious disease was consulted. Intraoperative cultures obtained grew <i>Aspergillus</i> and <i>Stenotrophomonas maltophilia</i>, although the <i>Aspergillus</i> was ultimately thought to be a contaminant. The patient was then placed on sulfamethoxazole-trimethoprim (SMX-TMP) for targeted antibiotic treatment. The patient responded well to the treatment regimen, with no signs of infection or further complications. Follow-up examinations have demonstrated full, painless knee range of motion and no adverse postoperative events. This case demonstrates a rare but significant injury in a pediatric patient secondary to a wild boar attack. Furthermore, though a systematic review was not conducted, no similar cases were identified in the available literature describing these bacterial isolates from a wild boar tusk within a traumatic arthrotomy. These findings may assist orthopedic surgeons, emergency physicians, and infectious disease specialists in antibiotic selection when these injuries are encountered to prevent subsequent complications.</p>","PeriodicalId":49360,"journal":{"name":"Wilderness & Environmental Medicine","volume":" ","pages":"10806032251347933"},"PeriodicalIF":1.4,"publicationDate":"2025-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144318477","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study reviewed 3 cases of Lyme carditis that presented to a tertiary hospital's emergency department in the northeastern United States during the summer months. The cases involved patients with varying degrees of atrioventricular (AV) block: first-degree, second-degree Type 2, and complete heart block. Case 1 involved a 19-y-old male presenting with syncope and diagnosed with first-degree AV block. He received intravenous (IV) ceftriaxone, resulting in resolution of the AV block. Case 2 was a 22-y-old male who experienced an unresponsive episode with bystander chest compressions. He had discrete erythematous patches and was diagnosed with Type 2 second-degree AV block. IV ceftriaxone followed by doxycycline resolved his condition without further incident. Case 3 described a 32-y-old male with lightheadedness and syncope, diagnosed with complete heart block. A temporary pacing lead and IV ceftriaxone were employed, transitioning to doxycycline, which effectively resolved the heart block. All three patients tested positive for Lyme antibodies with reflex Western blot. Lyme carditis presents variably, often without a clear history of tick exposure or erythema migrans. Prompt recognition and treatment in endemic areas are critical to prevent implantation of unnecessary permanent pacemakers. This paper underscores the importance of high clinical suspicion and reviews appropriate management in the emergency department setting for patients with potential Lyme carditis presenting with unexplained cardiac symptoms.</p>","PeriodicalId":49360,"journal":{"name":"Wilderness & Environmental Medicine","volume":" ","pages":"10806032251349439"},"PeriodicalIF":1.4,"publicationDate":"2025-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144286935","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
