Human papillomavirus (HPV) infection is believed to be the central cause of cervical cancer, although most of the epidemiological evidence has come from retrospective, case-control studies, which do not provide information on the dynamics of cumulative or persistent exposure to HPV infection. ⋯ A strong relationship exists between persistent HPV infections and SIL incidence, particularly for HPV types 16 and 18.

Adolescents who kill themselves invariably have an underlying psychiatric disorder. Biological markers are not yet clinically useful for identifying adolescents at risk, and there is a paucity of research data on the effectiveness of behavioral intervention for suicidal teenagers. ⋯ The importance of screening adolescent patients for depression is emphasized. Although teenage suicide is rare and hard to predict, identifying and treating adolescents at risk is essential to further reduce teenage suicide.

Suicide is a leading cause of death in the United States, but identifying persons at risk is difficult. Thus, the US surgeon general has made suicide prevention a national priority. An expanding body of research suggests that childhood trauma and adverse experiences can lead to a variety of negative health outcomes, including attempted suicide among adolescents and adults. ⋯ A powerful graded relationship exists between adverse childhood experiences and risk of attempted suicide throughout the life span. Alcoholism, depressed affect, and illicit drug use, which are strongly associated with such experiences, appear to partially mediate this relationship. Because estimates of the attributable risk fraction caused by these experiences were large, prevention of these experiences and the treatment of persons affected by them may lead to progress in suicide prevention.
