Adolescent risk taking and self-reported injuries associated with substance use.

Objective: To examine the incidence of adolescent substance use at the time of injury and its relation to risk-taking behavior.

Method: A total of 643 male and 782 female 9th through 12th grade students at three high schools anonymously completed surveys on any injuries that had occurred in the prior 6 months associated with substance use and risk-taking behavior.

Results: Males reported a higher incidence of injuries related to alcohol or other drugs than females (17.

Relationship between substance use and self-reported injuries among adolescents.

High school students (n = 1983), 14-18 years olds, were surveyed regarding the incidence of injury and substance use at the time of the injury in the prior 6 months. Alcohol or other drugs were reported particularly often for falls, cuts, and gun and assault injuries. Alcohol or other drugs were reported to be involved in a substantial proportion of injuries resulting in medical care, most notably for gunshots (70%), pedestrian injuries (42%) and physical fights (38%).

Risk taking, reported injury, and perception of future injury among adolescents.

Investigated the relationships among self-reported injury, risk taking, and perception of injury risk in a sample of 1,426 adolescents, 14 to 18 years old. Both risk taking and injury were higher in males than females across age groups. Having a friend injured the same way was the strongest predictor of injury, accounting for 28% of the variance.

Autosensitization to connective tissue elements and endogenous adaptation hormones in mycobacterioses.

The contribution of some adaptation hormones to the process regulating production of autoantibodies to collagen (Abc) and elastin (Abe) was studied in leprosy (37 patients) and tuberculosis (31 patients). In both mycobacterioses the Abc and Abe titers were increased and inversely correlated with endogenous cortisol levels. In leprosy the antibody titers directly correlated with the triiodothyronine (T3) levels which were significantly higher than the values in healthy controls.
