Differential Handling of Toxic Chemicals by Stress Shock Algae

Toxic shock syndrome: broadening the differential diagnosis.

BACKGROUND Toxic shock syndrome is a rare but potentially fatal toxin-mediated febrile illness. Although classically associated with tampon use, it is now known that many nonmenstrual conditions are related to this syndrome. Serious morbidity and mortality can occur if this syndrome is not promptly recognized. METHODS MEDLINE was searched from 1978 to the present using the phrase "toxic shock...

Contaminants may be of natural or of technological origin: and technological contaminants may be direct or i...
