High-altitude retinopathy and altitude illness
Ophthalmology, 1999To determine the relationship between high-altitude retinopathy (HAR) and other altitude-related illnesses and establish a classification system for HAR.Observational case series.All 40 climbers among 3 Himalayan expeditions who ascended to altitudes between 16,000 and 29,028 feet above sea level (summit of Mt.

We examined the effect of altitude up to 5200 m on marathon (42,195 m) performances.Eight elite and four good runners participated in a marathon at 4300-m altitude (A1), and five elite runners participated both in A1 and in a marathon at 5200-m altitude (A2).

Altitude poses physiological challenges to the sports participant in excess of those encountered at sea level. The main problem is hypoxia and the reduction in oxygen transport capacity, which is linked to the fall in alveolar oxygen tension. Training at altitude is imperative as preparation for competing there in aerobic events. The acute adaptations

Current Pain and Headache Reports, 2013
High altitude headache (HAH) has been defined by the International Headache Society as a headache that appears within 24 hours after ascent to 2,500 m or higher [1••]. The headache can appear in isolation or as part of acute mountain sickness (AMS), which has more dramatic symptoms than the headache alone.

In order to study the prevalence of hypertension and some of the factors relevant to its natural history, cross-sectional surveys were performed during the period 1967 to 1973 in five small Peruvian communities, two located at sea level and three above 13,000 feet of altitude.

Abstract The William P. Yant Memorial Award was established shortly after the death of Dr. Yant and was presented for the first time in 1965. The 1966 Yant Award, the second such presentation, was given to Dr. Alberto Hurtado, Research Director of the High Altitudes Research Institute, Peruvian University of Medical and Biological Sciences.

Emergency Medicine Clinics of North America, 1984
Altitude illness is a group of synergistic physiologic disturbances, each of which may occur alone but which more commonly occur together, with one dominating the clinical picture. Treated promptly, altitude illness is readily reversible with full recovery; procrastination may lead to death or disability.

High altitude retinopathy (HAR) was first described in 1969 as engorgement of retinal veins with occasional papilloedema and vitreous hemorrhage. Since then various studies have attempted to define the incidence, etiology and significance of this phenomenon, usually with small numbers of subjects. Recently studies on relatively large groups of subjects

High Alt Med Biol. 25:342-344, 2024.-Autoimmune myasthenia gravis (MG) is a condition commonly caused by the production of antibodies that block acetylcholine receptors. Until recently, gastrointestinal (GI) symptoms were considered rare in myasthenia gravis, but are now being proposed as an ...

Evidence frorn physiological studies indicates that hypoxia may act as a stress that reduces fecundity; and in human populations resident at high altitude there is evidence of reduced fe~i1ity (James, 1966). In this paper the fertility ofhigh Andean populations is described with reference to the ecological and social contexto An analysis of high Andean
