High Altitude De-acclimatization Syndrome: A Case Report.

High altitude de-acclimatization syndrome (HADAS) is a clinical entity that arises when individuals return abruptly from high-altitude environments to lower altitudes without undergoing the necessary acclimatization processes. While altitude-related illnesses have been extensively studied, HADAS remains relatively underreported and may pose diagnostic challenges due to its varied and nonspecific clinical presentation. This case report aims to shed light on the importance of recognizing HADAS as a potential consequence of inadequate acclimatization, emphasizing the need for a thorough understanding of altitude-related disorders in individuals with a history of rapid altitude changes.

Pregnancy and non-valvular heart disease--anesthetic considerations.

Non-valvular heart disease is an important cause of cardiac disease in pregnancy and presents a unique challenge to the anesthesiologist during labor and delivery. A keen understanding of the underlying pathophysiology, in addition to the altered physiology of pregnancy, is the key to managing such patients. Disease-specific goals of management may help preserve the hemodynamic and ventilatory parameters within an acceptable limit and a successful conduct of labor and postpartum period.
