High altitude pulmonary edema (HAPE) in a Himalayan trekker: a case report.

Introduction: High altitude pulmonary edema is a non-cardiogenic form of pulmonary edema that develops in unacclimatized individuals at altitudes over 2500 m. Early recognition of symptoms and immediate descent are important for successful treatment. Despite early signs and symptoms of high altitude illness, many trekkers tend to push themselves to the maximum limit.

Cerebral venous sinus thrombosis at high altitude.

Cerebral venous sinus thrombosis (CVST) is a rare but potentially life-threatening medical condition. We describe a case of a 47-year-old woman who presented with headache, speech defects, and visual disturbances, and was later diagnosed with cerebral venous sinus thrombosis. The article describes a possible risk of such thrombotic events with exposure to high altitude environment in patients with coagulation defects such as Factor V Leiden mutation.
