Social and Structural Influences on Multiracial Identification and Health: a Public Health Mandate to Precisely Measure, Theorize, and Better Understand Multiracial Populations.

There is a growing group of adolescents and young adults in the USA who identify as multiracial. However, very little research, especially health research, focuses on understanding multiracial identification and health and behavioral outcomes for multiracial populations in comparison to their single-race counterparts. Understanding the intersectional influences on this identification process is critical to updating the literature on racial and ethnic identity and health with more accurate identifications and categories. It is especially critical that there is an explicit focus on understanding the impact of structural racism and discrimination when studying the process of racial identification and the impact on health. This review takes an interdisciplinary approach relying on a review of multiple research literatures: the historical literature on race, racism and categorization, psychological and adolescent medicine literatures on adolescent development, the sociological literature on racial and ethnic identification, and the limited public health research beginning to disentangle multiracial health outcomes. An empirically testable conceptual framework is offered to frame the organization of this review-demonstrating the multiple spheres of influence on racial and ethnic identification and the implication for health outcomes.

Prevention of suicide in adolescents.

Suicide is a major public health problem in the United States. Suicide and attempted suicide are important causes of morbidity and mortality in adolescents. Epidemiologic trends in adolescent suicide point to increasing rates of suicide and increasing access to lethal attempts, particularly firearms. It is important for clinicians to recognize risk factors for suicide, but it is even more important to screen all adolescents for suicidal thoughts and feelings. This article highlights important publications from the past year (April 2000 to April 2001) regarding adolescent suicidal behavior, with particular focus on risk factors, recognition, and management.

Selective use of ultrasonography for acute appendicitis in children.

BACKGROUND: To evaluate the role of ultrasonography in children with equivocal signs of acute appendicitis, and correlate with initial clinical impression and pathological findings. METHODS: This is a prospective evaluation of all children presenting with a possible diagnosis of appendicitis during a 14-month study period. Patients with unequivocal clinical signs of appendicitis underwent appendectomy without ultrasonography. Patients with equivocal signs had documentation of the clinical impression and subsequent abdominal ultrasound. Statistical analysis of results was performed using the chi-square test (P <0.05 significant). RESULTS: Two hundred fifteen consecutive children were enrolled. Signs were unequivocal in 116 and equivocal in 99. Seven patients in the first group had a normal appendix at operation. Of the 99 patients with equivocal signs, there were 28 true positives, 3 false positives, 64 true negatives, and 4 false negatives. In equivocal cases, sensitivity of the initial clinical impression versus ultrasound was 50% and 88%, respectively (P <0.05). Specificity was 85% and 96%, respectively. The positive and negative predictive values improved from 63% to 90% and 78% to 94%, respectively, with the use of ultrasonography. CONCLUSIONS: The low false positive rate (6%) in clinically obvious cases of appendicitis does not, in our opinion, warrant ultrasonography. In clinically equivocal cases, ultrasonography is a fast, sensitive, and specific diagnostic modality to diagnose or rule out appendicitis, avoiding the need for prolonged observation and/or hospitalization.
