Selections from current literature: the traveller to high altitude.
AMS is a preventable disease about which travellers are frequently uninformed and one which physicians may wrongfully assume is limited to the population of ultra high altitude adventurers. These studies on incidence, while not without flaws, point out the frequency of AMS, as well as its significant incidence at moderate and commonly frequented altitudes. The current literature does not fully answer questions about incidence at moderate altitudes, nor about the full effects of altitude on children. Certainly AMS is not a rare complication of travel to altitudes and may indeed be under-recognized and under-treated. Both acetazolamide and dexamethasone provide adequate prophylaxis, and the choice of medications can be to some extent based on experience and patient profile. The best prophylaxis is a slow stepwise ascent, and the best treatment descent. The availability of medications for the amelioration or prevention of symptoms, and succinct advice on prevention by travel planning will make many of our patients' holidays more enjoyable and business trips more productive.
