Primary Intraosseous Squamous Cell Carcinoma Arising from a Dentigerous Cyst of the Maxillary Wisdom Tooth.

The World Health Organization defines primary intraosseous squamous cell carcinoma (PIOSCC) as a squamous cell carcinoma (SCC) arising primarily within the jaws and having no connection with the oral mucosa. Here, we report a case of PIOSCC in which it was difficult to differentiate the condition from pericoronitis of an impacted maxillary wisdom tooth. The patient was a 27-year-old pregnant woman with a pain in the right maxillary wisdom tooth.

Predicting American Indian adolescent substance use trajectories following inpatient treatment.

This study examined the effects of psychopathological, peer, family, and cultural predictors of American Indian adolescents' drug use following inpatient treatment. Data regarding lifetime, 90 days prior to treatment, and 1-year posttreatment substance use were collected using interviews, questionnaires, and observations of 57 American Indian adolescents and their families. Trajectories of days-used measures were subjected to semiparametric trajectory analysis.

An ecological approach to promoting early adolescent mental health and social adaptation: family-centered intervention in public middle schools.

This study examined the impact of the Family Check-Up (FCU) and linked intervention services on reducing health-risk behaviors and promoting social adaptation among middle school youth. A total of 593 students and their families were randomly assigned to receive either the intervention or middle school services as usual. Forty-two percent of intervention families engaged in the service and received the FCU.

Cascading peer dynamics underlying the progression from problem behavior to violence in early to late adolescence.

This study examined the peer dynamics linking early adolescent problem behavior, school marginalization, and low academic performance to multiple indices of late adolescent violence (arrests, parent report, and youth report) in an ethnically diverse sample of 998 males and females. A cascade model was proposed in which early adolescent risk factors assessed at age 11 to 12 predict gang involvement at age 13 to 14, which in turn, predicts deviancy training with friends at age 16 to 17, which then predicts violence by age 18 to 19. Each construct in the model was assessed with multiple measures and methods.

Weight loss and PTSD symptom severity in former POWs.

To determine the relationship between weight loss suffered by former prisoners of war during captivity during World War II and the Korean Conflict and current posttraumatic stress disorder (PTSD) symptoms, the Clinician-Administered PTSD Symptom Scale, a lifetime stressor checklist, and the Structured Clinical Interview for DSM-IV were administered to 102 former prisoners of war. Preconfinement and postconfinement weights and length of confinement were obtained from military medical records. Percentage of body weight lost during captivity was significantly higher in those subjects with PTSD and correlated with current PTSD symptom severity.
