The authors describe a case of air embolism that developed during a plane flight in a woman who had a congenital cystic adenomatoid malformation. They review the pathophysiological mechanisms, risk factors, clinical features, and treatment of air embolism.

For several days, a 50-year-old man has had copious green stools, vomiting, and fever. His symptoms began shortly after he was discharged from a regional burn center, where he was treated for full-thickness burns that covered 60% of his body surface.

A 39-year-old woman complained of excruciating pain that radiated from a chronic lesion on the left upper lip to the entire left side of the face. She had AIDS but was not receiving antiretroviral therapy.

SYDNEY -- A novel HIV drug aimed at barring entry of the virus into the cell was safe and had a long half-life in an early trial, lowering viral load for up to two weeks after treatment stopped, a researcher said here.

SYDNEY -- HIV vaccine research is poised to take a step into the unknown -- the use of live but attenuated viruses to create immunity.
