Three rare presentations of high-altitude pulmonary edema at a high-altitude clinic in the Everest region (4371 m): A case series.

Diagnosis of HAPE can be challenging when the presentation deviates from usual natural history. Point of care ultrasonography serves as a great diagnostic tool in such settings. An umbrella treatment could be beneficial during such scenarios.

Morbidity Among Athletes Presenting for Medical Care During 3 Iterations of an Ultratrail Race in the Himalayas.

INTRODUCTION: Although ultratrail races are increasing in popularity, there is a dearth of data regarding illnesses and medical care at these events. Data about injuries and illnesses for races taking place in the Himalayas, where the nearest medical facility can be hundreds of miles away, are even harder to find. This study aimed to describe the injuries and illnesses befalling the participants of a 7-stage 212 km (132 mi) trail race at high altitude. METHODS: Ethical approval was obtained from Nepal Research Health Council. A retrospective study of the record of medical encounters among the 100 participants competing in the Manaslu trail race in Nepal from 2014 to 2016 was performed. Diagnoses were classified into various categories. Informed consent was taken from all participants. RESULTS: Acute diarrhea was the most common ailment reported among the participants (18%), followed closely by musculoskeletal problems (17%). Altitude illness made up 6% of care provided. Approximately 35% of the athletes were using acetazolamide as prophylaxis for high altitude illnesses. The 1 case needing evacuation in the 3 iterations was high altitude pulmonary edema. CONCLUSIONS: Ultratrail races at high altitude pose a challenge in terms of provision of medical care in a remote setting with limited resources. However, most of the illnesses are minor in nature and easily managed by the race doctor. Knowledge of common illnesses among travelers to the area can help aid in preparation and provision of proper care, especially in remote settings with limited resources.

A Review of Medical Problems in Himalayan Porters.

Porters have accompanied trekkers and climbers to high altitude since the earliest expeditions in the Himalayas. As the existing body of knowledge on high-altitude medicine expands, the focus remains on trekkers or climbers. And published literature on medical problems in the large porter population remains sparse. It is well known that porters working at high altitude in the Nepal Himalayas are often lowland dwellers and are as prone to high-altitude illnesses such as acute mountain sickness, high-altitude pulmonary edema, and high-altitude cerebral edema as the trekkers are. Other illnesses such as diarrhea, respiratory illnesses, and infections also occur in this population. In this review, studies reporting these findings will be discussed along with the local context of socioeconomic barriers to adequate health care for these porters.

Friction Blister by Climbing Harness: A Case Report.

An experienced 24-y-old climber on Mount Everest presented to the Base Camp medical clinic with a friction blister on his right flank. The blister was filled with clear fluid and was located about 3 cm posterior and 3 cm superior to the highest point of the right iliac crest, the site where a climbing harness would support the climber while hanging. A diagnosis of friction blister caused by a climbing harness used while traversing between Camp 2 and Camp 3 of Mount Everest was made. The blister was managed with hydrocolloid dressing, and the patient resumed climbing after 1 wk. The lesion healed with scarring at 2 wk. Friction blisters of the feet are common in climbers wearing ill-fitting shoes, but friction blisters caused by climbing harnesses are unusual and have not been reported in the literature as far as the authors are aware. All existing guidelines for blister management pertain to blisters of the feet, and there are inconsistencies in recommendations made by various authors. This unusual case in an extreme environment provides a good learning opportunity.

Successful Summit of Two 8000 m Peaks After Recent High Altitude Pulmonary Edema.

There is little information in the literature on the safety of reascent to high altitude shortly after resolution of severe acute altitude illness, including high altitude pulmonary or cerebral edema. We present a case of a 52-y-old male climber who was diagnosed with high altitude pulmonary edema during the 2018 Everest spring climbing season, descended to low altitude for 9 d, received treatment, and returned to continue climbing with a very rapid ascent rate. Despite a very recent history of high altitude pulmonary edema and not using pharmacologic prophylaxis over a very rapid reascent profile, the climber successfully summited Mt. Everest (8848 m) and Lhotse (8516 m) without any problems.

Posterior reversible encephalopathy syndrome (PRES) in a patient with late postpartum eclampsia.

Posterior reversible encephalopathy syndrome (PRES) is a reversible neurological entity characterised by seizure, headaches, visual symptoms, impaired consciousness and other focal neurological findings. It is caused by a wide variety of causes ultimately leading to a vasogenic cerebral oedema of occipital and parietal lobes of the brain. We present here a young woman with headache, generalised tonic-clonic seizures and cortical blindness in a late postpartum stage. Reversibility of the symptoms and characteristic imaging findings led us to a diagnosis of PRES in our patient.
