Characteristics of Spinal Cord Injury Presenting to Tertiary Care Center in Gandaki province of Nepal: A Descriptive Cross-sectional Study.

INTRODUCTION: Spinal cord injury is one of the common injury which causes damage to the spinal cord due to trauma, diseases or degenerations leading to disability and decreasing life expectancy. The study aims to find the characteristics of spinal cord injury presenting at a tertiary care centre. METHODS: A Descriptive hospital based cross-sectional study was conducted at Pokhara, Gandaki Province, from 28th March to 25th September, 2023. 139 participants were interviewed for the study. Structured interview schedule and validated questionnaires were used for data collection. Ethical approval was taken for the study (Reference number: 151/079). RESULTS: A total of 139 cases were observed; most common affected age group was between 25-55 years with a mean age of 48.68 years. Most (66.9%) of the spinal cord injury patients were not enrolled in health insurance program. Most 107 (77.0%) common cause for spinal cord injury was falls from height. Age, gender, occupation and duration of stay in the hospital were statistically significant with mode of treatment. CONCLUSIONS: Spinal cord injury mostly traumatic commonly due to fall from height affecting mainly male population residing in rural areas at their fourth decade of life who are mainly involve in manual work and agriculture. Spinal cord injury is a major health problem at global and local level causing major morbidity.

Acclimatisation in trekkers with and without recent exposure to high altitude.

In mountaineers, recent altitude exposure has been shown to improve climbing performance and clinical outcomes during re-exposure to high altitude. However, the timing of previous altitude exposure has not been clearly reported and previous findings might be driven by individuals who were still acclimatised at the time of re-exposure. Our goal was to determine whether recent altitude exposure would confer an advantage even in individuals who had de-acclimatised for ≥ 1 week before being re-exposure. Low-altitude natives kept a daily trekking log throughout 7- to 8-day trek from Lukla (2,840 m) to Gokyo Ri (5,360 m). Trekkers with recent altitude exposure (re-acclimatisers, RA; n = 20) walked 20% faster (p < 0.01), reported lower acute mountain sickness scores (9 ± 8 vs. 15 ± 13; p = 0.02), and used less medication to treat headache (p < 0.05) compared to trekkers with no recent altitude exposure (initial acclimatisers, IA; n = 30). On Gokyo Ri, S(p)O(2) was significantly higher in RA than IA trekkers (85 ± 6 vs. 78 ± 6; p = 0.01). These data indicate improved functional outcomes and physiological compensation for hypoxia in RA. However, even after de-acclimatisation for 7-30 days, it is possible that RA trekkers began the trek in a more acclimatised state than IA trekkers. RA trekkers might represent a self-selected group that has previously tolerated altitude well and has therefore opted to return. Some findings might also reflect improved psychological altitude tolerance in RA. A direct comparison of the functional and physiological responses to hypoxia throughout an initial and re-acclimatisation to high altitude is needed.

Frostbite in a Sherpa.

Frostbite is frequently seen in high altitude climbers. Many Sherpas, members of an ethnic community living high in the Himalayas in Nepal, help the climbers as a guide or an assistant. They often seem to undertake few precautionary measures thus suffer more from frostbite. A young Sherpa, who had reached the top of Mt Kanchenjunga in March 2009, suffered from deep frostbite in his fingers. Fortunately, he recovered well with generous treatment. Though there is no evidence whether Sherpas are more or less prone to frostbite, simple techniques for adequate prevention of hypoxia, hypothermia and dehydration will benefit any climber to the high altitudes.

Complications of steroid use on Mt. Everest.

Steroids are used for the prevention and treatment of high-altitude illnesses. However, these agents can cause significant side effects. We report a case of altered mental status, gastrointestinal bleeding, skin rash, and avascular necrosis in a climber taking prophylactic dexamethasone prior to an attempt to climb Mt Everest. High-altitude cerebral edema (HACE), steroid toxicity, and acute adrenal crisis can have similar clinical presentations. Differentiating between these life-threatening conditions at high altitude is essential for successful treatment.

Another typhoid patient from Japan.

Typhoid treatment was empirically started in a Japanese patient with undifferentiated fever in Nepal since Japanese tourists, unlike most Americans and Europeans to South Asia, are unable to obtain typhoid vaccination in Japan even for travel to this area of high endemicity. Subsequently, his blood culture grew out Salmonella typhi.
