Randomized Controlled Trial Clinical Trial
Frequency and prevention of symptomless deep-vein thrombosis in long-haul flights: a randomised trial.
The true frequency of deep-vein thrombosis (DVT) during long-haul air travel is unknown. We sought to determine the frequency of DVT in the lower limb during long-haul economy-class air travel and the efficacy of graduated elastic compression stockings in its prevention. ⋯ We conclude that symptomless DVT might occur in up to 10% of long-haul airline travellers. Wearing of elastic compression stockings during long-haul air travel is associated with a reduction in symptomless DVT.

Herpes simplex virus (HSV) is a member of the herpesviridae family. Recognised since ancient Greek times, the virus frequently infects human beings, causing a range of diseases from mild uncomplicated mucocutaneous infection to those that are life threatening. In the past 50 years, substantial advances in our knowledge of the molecular biology of HSV have led to insights into disease pathogenesis and management. This review provides a contemporary interpretation of the biological properties, function, epidemiology, and treatment of HSV diseases.
