Before and after the trauma bay: the prevention of violent injury among youth.

Despite a decline in the incidence of homicide in recent years, the United States retains the highest youth homicide rate among the 26 wealthiest nations. Homicide is the second leading cause of death overall and the leading cause of death for male blacks aged 15 to 24 years. High rates of health care recidivism for violent injury, along with increasing research that demonstrates the effectiveness of violence prevention strategies in other arenas, dictate that physicians recognize violence as a complex preventable health problem and implement violence prevention activities into current practice rather than relegating violence prevention to the criminal justice arena. The emergency department (ED) and trauma center settings in many ways are uniquely positioned for this role. Exposure to firearm violence doubles the probability that a youth will commit violence within 2 years, and research shows that retaliatory injury risk among violent youth victims is 88 times higher than among those who were never exposed to violence. This article reviews the potential role of the ED in the prevention of youth violence, as well as the growing number of ED- and hospital-based violence prevention programs already in place.

Evaluation of poststreptococcal illness.

Group A beta-hemolytic streptococcal pharyngitis, scarlet fever, and rarely asymptomatic carrier states are associated with a number of poststreptococcal suppurative and nonsuppurative complications. As in streptococcal pharyngitis, acute rheumatic fever, pediatric autoimmune neuropsychiatric disorders associated with streptococcal infection, and poststreptococcal glomerulonephritis most often occur in children. The hallmarks of rheumatic fever include arthritis, carditis, cutaneous disease, chorea, and subsequent acquired valvular disease. Pediatric autoimmune neuropsychiatric disorders encompass a subgroup of illnesses involving the basal ganglia in children with obsessive-compulsive disorders, tic disorders, dystonia, chorea encephalitis, and dystonic choreoathetosis. Poststreptococcal glomerulonephritis is most frequently encountered in children between two and six years of age with a recent history of pharyngitis and a rash in the setting of poor personal hygiene during the winter months. The clinical examination of a patient with possible poststreptococcal complications should begin with an evaluation for signs of inflammation (i.e., complete blood count, erythrocyte sedimentation rate, C-reactive protein) and evidence of a preceding streptococcal infection. Antistreptolysin O titers should be obtained to confirm a recent invasive streptococcal infection. Other important antibody markers include antihyaluronidase, antideoxyribonuclease B, and antistreptokinase antibodies.
