Purpose Of Review: One of the strongest arguments for the immune surveillance network of antibodies and sensitized cytotoxic T cells is the extraordinary incidence of lymphoid malignancy in the many types of primary immunodeficiency.
Recent Findings: This review updates the literature that seems to wax and wane on the importance of specific immunity to malignant cell antigens by previous authors. This new survey strongly supports the tenet that immune responses protect from malignant cell growth and development, much like it protects against a hostile microbial world.
Objective: The authors assessed the relationship between traffic accidents and drowsiness.
Material And Method: A self-answered questionnaire survey of 4331 commercial bus/truck drivers was done.
Result: Sixty-nine percent of the drivers reported accidents and one third of these accidents was attributable to drowsiness.
