Incidence and circumstances of nonfatal firearm-related injuries among children and adolescents.

OBJECTIVE: To describe the incidence and circumstances of nonfatal firearm-related injuries among children and adolescents treated in US emergency departments. DESIGN: Data were obtained from the Firearm Injury Surveillance Study, 1993-1997; data were collected through medical record review at hospitals participating in the National Electronic Injury Surveillance System. SETTING: The hospitals participating in National Electronic Injury Surveillance System are a stratified probability sample of all US hospitals. MAIN OUTCOME MEASURES: Numbers and population rates for nonfatal firearm-related injuries among children and adolescents younger than 20 years old. RESULTS: An estimated 115,131 (95% confidence interval, 76,769-153,493) children and adolescents were treated for a nonfatal gunshot wound during the study period. The estimated annual rates of injury (per 100,000) were 2.0 (children 0-4 years old), 2.2 (children 5-9 years old), 15.4 (children 10-14 years old), and 106.5 (adolescents 15-19 years old). The ratios of nonfatal to fatal firearm-related injuries were 4.0 (children 0-4 years old), 4.4 (children 5-9 years old), 5.0 (children 10-14 years old), and 4.4 (adolescents 15-19 years old). An additional estimated 103,814 children (95% confidence interval, 69,223-138,405) were shot with a nonpowder firearm (BB or pellet gun). Boys 5 to 9 and 10 to 14 years old had the highest rates of injury related to nonpowder firearms, an estimated 36.2 and 99.8 per 100,000, respectively. Fifty-six percent of those 15 to 19 years old were assault victims. An estimated 48% of children and adolescents with powder firearm-related gunshot wounds and an estimated 4% with nonpowder firearm injuries were admitted to the hospital. CONCLUSIONS: Nonfatal injuries related to powder firearms and nonpowder firearms (BB or pellet guns) are an important source of injury among US children and adolescents. Ongoing surveillance of nonfatal firearm-related injury among children and adolescents is needed.

New approaches to the treatment of group A streptococcal pharyngitis.

An orally administered antimicrobial regimen for the treatment of pharyngitis caused by group A beta-hemolytic streptococci that could be given once daily and for less than 10 days would be convenient and might improve compliance, decrease cost, and result in fewer side effects compared with a regimen given multiple times daily for 10 days. Previous attempts to administer oral penicillin once daily or for less than 10 days were not successful. Several cephalosporins and azithromycin have been reported to be effective when administered once daily or for less than 10 days. However, large, comprehensive studies have not been performed. In addition, the spectra of these cephalosporins and azithromycin are much broader than that of penicillin, and, even when they are administered for short courses, they are more expensive. Therefore, these novel regimens cannot be endorsed and should not supplant penicillin as the agent of choice. In contrast, once-daily amoxicillin therapy appears to be effective, is inexpensive, and has a narrower spectrum of antimicrobial activity; if these findings are confirmed by additional investigations, it could become an alternative regimen for the treatment of pharyngitis caused by group A beta-hemolytic streptococci.

Cycling injuries treated in emergency departments: need for bicycle helmets among preschoolers.

OBJECTIVES: To describe the incidence, circumstances, and severity of bicycle-related injuries among children treated in US emergency departments (EDs) and to compare injuries in children aged 1 to 4 years (young children) with those in children and adolescents aged 5-9 and 10-14 years (intermediate-age and older children, respectively). DESIGN: Emergency department survey from the National Center for Health Statistics National Hospital Ambulatory Medical Care Survey for January 1, 1992, through December 31, 1997. PATIENTS: National probability sample of patients who sought care in EDs; data for children 1 to 14 years old were used. OUTCOME MEASURES: Incidence and description of bicycle-related injuries among children grouped by age treated in US EDs. RESULTS: The 6-year weighted estimate of bicycle-associated injuries was 2,176,173. Young children had 270,098 ED visits; their average annual incidence was 45,016, a rate of 28.8 per 10,000 (95% confidence interval [CI], 19.1-38.5). Children in the intermediate-age and older groups had an incidence of 82.0 (95% CI, 66.6-97.4); and 86.4 (95% CI, 70.4-102.4) per 10,000, respectively. The highest rates of bicycle-related injuries were observed among boys in the intermediate-age (108.3 per 10,000 per year) and older groups (123.8 per 10,000 per year). Few injured children were involved in collisions with motor vehicles (<1% of young and 4% of intermediate-age groups). The annual incidence of head trauma was 4.0 per 10,000 (95% CI, 0.4-7.5) for young children, 9.3 per 10,000 (95% CI, 4.3-14.2) for intermediate-age children, and 8.1 per 10,000 (95% CI, 3.5-12.8) for older children. Children aged 5 to 9 years had the highest rates of face trauma (estimated 29.8 per 10,000). The incidence of extremity fractures (range, 6.9-17.6 per 10,000) was similar for all groups. CONCLUSIONS: Although boys in the intermediate-age and older groups have the highest incidence of bicycle-related injuries, young children are also commonly injured. The anatomic sites of injury among young cyclists (head and face trauma and extremity fractures) are similar to those observed in both other groups. Bicycle helmets are indicated for the youngest children as well.

Convenient schedules and short course treatment of acute streptococcal pharyngitis.

A number of options exist for reducing the frequency of antibiotic dosing and shortening the course of treatment of GAS pharyngitis. All oral agents are more costly than oral penicillin and have a broader spectrum of antimicrobial activity. These issues must be weighed against the convenience of these treatment regimens. At this time penicillin remains the drug of choice for acute streptococcal pharyngitis. Oral penicillin V can be given twice daily for 10 days. Intramuscular benzathine penicillin is inexpensive and obviates any concerns about compliance. For penicillin-allergic patients, twice daily erythromycin for 10 days is preferred but azithromycin once a day for 5 days is a reasonable (but expensive) alternative.

Tykes and bikes: injuries associated with bicycle-towed child trailers and bicycle-mounted child seats.

OBJECTIVES: To describe the incidence, type, and severity of injuries related to the use of bicycle-towed trailers for transporting children and to compare them with injuries associated with the use of child seats mounted on adult bicycles. DESIGN: A retrospective analysis of data from the National Electronic Injury Surveillance System of the US Consumer Product Safety Commission for 1990 to 1998. RESULTS: There were 49 injuries to children during the 9-year study period (estimated 2338 injuries; 95% confidence interval [CI], 1121-3555): 6 were associated with the use of bicycle-towed trailers (an estimated 322 injuries; 95% CI, 158-486) and 43 were related to the use of bicycle-mounted child seats (an estimated 2015 injuries; 95% CI, 988-3042). The mean age of injured children was 2.4 years and 51% were male. A collision with a motor vehicle accounted for 2 (33%) of the injuries associated with bicycle-towed trailers; 3 (50%) of the injuries were the result of falls. A motor vehicle was involved in 4 injuries (9%) related to the use of bicycle-mounted child seats (Fisher exact test, P<.13 vs bicycle-towed trailers); 31 (72%) were the result of falls (Fisher exact test, P<.26 vs bicycle-towed trailers). Contact with a bicycle wheel or spokes was the mechanism of 1 injury associated with the use of a bicycle-towed trailer (17%) and the mechanism for 8 (19%) of the injuries associated with the use of a bicycle-mounted child seat (Fisher exact test, P<.69). The head or face was the most common site of injury, accounting for 5 (83%) injuries among those riding in bicycle-towed trailers and 21 (49%) injuries among children in bicycle-mounted child seats (Fisher exact test, P<.12). All 6 children injured in bicycle-towed trailers had contusions/ abrasions or lacerations; 22 (51%) children injured using bicycle-mounted child seats had contusions/abrasions or lacerations and 9 (21%) had fractures. Two children (33%) injured in bicycle-towed trailers and 2 (5%) injured in bicycle-mounted child seats were admitted to the hospital (Fisher exact test, P<.06). CONCLUSIONS: When compared with bicycle-mounted child seats, there were fewer reported injuries to children associated with the use of bicycle-towed trailers. Motor vehicle involvement and need for hospital admission were similar among injured children in both groups, and the head or face was the most common site of injury. These data imply that ongoing surveillance efforts to identify injuries associated with use of bicycle-towed child trailers are warranted and that bicycle helmets should be worn by children riding in bicycle-towed child trailers and in bicycle-mounted child seats.

Injury prevention education using pictorial information.

BACKGROUND: Written materials used in pediatric public health settings often exceed the reading skills of caretakers. OBJECTIVE: To compare a pictorial anticipatory guidance (PAG) sheet requiring limited reading skills to a TIPP (The Injury Prevention Program) sheet for providing injury prevention information to low-income urban families. DESIGN AND SETTING: A convenience sample of families with children treated at an urban pediatric clinic affiliated with a teaching hospital. Methods. Parents of children

Potential mechanisms for failure to eradicate group A streptococci from the pharynx.

OBJECTIVE: To investigate the relative efficacy of orally administered cefadroxil and penicillin V in the treatment of group A streptococcal (GABHS) pharyngitis and the mechanism(s) responsible for failure of antimicrobial therapy to eradicate GABHS from the pharynx. STUDY DESIGN: A prospective, randomized clinical trial was conducted in four pediatric offices in which 462 patients with acute pharyngitis and positive culture for GABHS were randomly assigned to receive cefadroxil (n = 232) or penicillin V (n = 230). RESULTS: Bacteriologic treatment success rates for patients in cefadroxil and penicillin groups were 94% and 86%, respectively. However, among patients classified clinically as likely to have bona fide GABHS pharyngitis, there was no difference in bacteriologic treatment success rates in cefadroxil and penicillin groups (95% and 94%, respectively). Among patients classified clinically as likely to be streptococcal carriers, bacteriologic treatment success rates in cefadroxil and penicillin groups were 92% and 73%, respectively. The presence of beta-lactamase and/or bacteriocin-producing pharyngeal flora had no consistent effect on bacteriologic eradication rates among patients in either penicillin or cefadroxil treatment groups or among patients classified as having either GABHS pharyngitis or streptococcal carriage. CONCLUSIONS: Neither beta-lactamase nor bacteriocin produced by normal pharyngeal flora are related to bacteriologic treatment failures in GABHS pharyngitis. Cefadroxil seems to be more effective than penicillin V in eradicating GABHS from patients classified as more likely to be streptococcal carriers. However, among patients we classified as more likely to have bona fide GABHS pharyngitis, the effectiveness of cefadroxil and penicillin V seems to be comparable.

Child and adolescent injury and death from urban firearm assaults: association with age, race, and poverty.

OBJECTIVE: To describe rates and trends in the incidence of non-fatal and fatal firearm assault among children (16 years old or younger) over an 11 year period in Chicago, Illinois and to identify the socioeconomic characteristics of community areas where assaults are common. METHODS: The Chicago Police Department (CPD) records from 1986 through 1996 were reviewed for children assaulted with a firearm. United States census data for 1990 for Chicago were used to calculate incidence rates; census data were also used for community area (defined by census tract) socioeconomic descriptions. RESULTS: The CPD recorded 11,163 pediatric firearm assaults during the study period: 10,571 non-fatal and 592 (5%) fatal. From 1986 through 1996 non-fatal assaults more than doubled, with the highest rates in 1994; fatal assaults tripled, with rates peaking in 1993-94. Significant increases in non-fatal firearm assaults occurred among black and Hispanic males and females. In 1994, compared with white males, the relative risk of non-fatal assault was 7.0 (95% confidence interval (CI) 5.3 to 9.1) for black males and 3.3 (95% CI 2.5 to 4.4) for Hispanic males; the relative risk was 1.5 (95% CI 1.1 to 2.1) for black females. A handgun was the firearm used in most assaults (88% of non-fatal and 84% of fatal). Within community areas, the correlation between non-fatal and fatal assault incidence was strong (r=0.80, p<0.001). The proportion of families with income below the 1989 poverty level ($12,674) and the per cent black race in the community area together accounted for 70% of the variance in assault rates. CONCLUSIONS: From 1986 to 1994 there were significant increases in both non-fatal and fatal firearm assaults, usually by handguns; thereafter, rates declined. Urban children who were victims of non-fatal firearm assault appear to come from the same population as those who suffer fatal assaults. Black and Hispanic youth living in poverty were at particular risk.
