A U-Shaped Association Between Intensity of Internet Use and Adolescent Health

Internet use has rapidly become a commonplace activity, especially among adolescents. Poor mental health and several somatic health problems are associated with heavy Internet use by adolescents.

Results of this study provide evidence of a U-shaped relationship between intensity of Internet use and poorer mental health of adolescents. Heavy Internet users were also confirmed to be at increased risk for somatic health problems in this nationally representative sample of adolescents. (Read the full article)

Cigarette Advertising and Teen Smoking Initiation

It has been well documented that exposure to tobacco marketing is a risk factor for smoking initiation among youth. However, few studies have tested the specificity of this association.

This study extends findings from other studies and shows (from a longitudinal design) that exposure to cigarette advertising is significantly associated with youth smoking initiation, whereas exposure to advertising for other commercial products is not. (Read the full article)

Nonurgent Emergency-Department Care: Analysis of Parent and Primary Physician Perspectives

Many patient and family demographic characteristics are well-known risk factors for nonurgent emergency-department use. No previous study has examined the primary care physician perspective on parental decisions regarding specific nonurgent emergency-department visits by children.

When discussing specific instances when families in their practices sought nonurgent care for children in the emergency department, physicians believed that parents acted appropriately. Neither parents nor primary care physicians saw nonurgent emergency-department visits as a significant enough problem to warrant change. (Read the full article)

Hearing Screening in a Well-Infant Nursery: Profile of Automated ABR-Fail/OAE-Pass

Combined auditory brainstem response/otoacoustic emission testing is used to screen for auditory neuropathy spectrum disorder (ANSD), which leads to failure to develop normal auditory behavior and oral language. Prevalence estimates have been obtained for infants in NICUs.

ANSD risk in well-infant nurseries has not been examined. This study contributes ANSD prevalence estimates for infants admitted to well-infant nurseries and compares the costs of 2 different 2-technology screening protocols. (Read the full article)

Impact of Rotavirus Vaccination on Hospital-Acquired Rotavirus Gastroenteritis in Children

Approximately 27% of children with rotavirus in the hospital acquire it while hospitalized for another condition. Pediatric rotavirus vaccination greatly decreased the number of children hospitalized with rotavirus from 2007 to 2008.

Routine community-based rotavirus infant vaccination protects hospitalized children from acquiring rotavirus. Thus, community-based vaccination efforts should be encouraged as a strategy to decrease hospital-acquired rotavirus. (Read the full article)

Noninvasive Ventilation for Respiratory Distress Syndrome: A Randomized Controlled Trial

Nasal continuous positive airway pressure (NCPAP) has been the initial respiratory support for many preterm infants with respiratory distress syndrome (RDS). Nasal intermittent positive-pressure ventilation (NIPPV) seems to increase the beneficial effects of NCPAP by combining it with ventilatory inflations.

This study suggests that NIPPV, as an intial respiratory support for preterm infants with RDS, is feasible and safe and may have beneficial effects, when compared with NCPAP. (Read the full article)

Current Referral Patterns and Means to Improve Accuracy in Diagnosis of Undescended Testis

Primary care providers (PCPs) identify patients with undescended testis (UDT) and refer them to surgical specialists. Referral beyond the recommended times for orchiopexy has been reported, and PCPs' accuracy in identifying and distinguishing UDTs from retractile testes has been questioned.

We describe 3 observations that are strongly correlated with UDT, that is, birth history of UDT, prematurity, and visible scrotal asymmetry. UDT diagnoses are best made by 8 months of age, to reduce confusion with testicular retraction and to facilitate timely orchiopexy. (Read the full article)

Prospective Assessment of Practice Pattern Variations in the Treatment of Pediatric Gastroenteritis

Although gastroenteritis guidelines describe the need to perform oral rehydration, it remains underused, resulting in excessive use of intravenous rehydration. Other interventions, such as antiemetic administration, vary according to location, often resulting in differences in cost and outcomes.

In this nationwide cohort, intravenous rehydration use varied dramatically. Use was associated with the institution providing care and an increase in the need for future health care provider visits. Use of ondansetron also varied significantly across Canada. (Read the full article)

Chlamydia Screening Among Young Women: Individual- and Provider-Level Differences in Testing

Chlamydia testing among adolescents and young women without symptoms is recommended by the US Preventive Services Task Force, but only approximately one-half of eligible young women presenting for health care are screened appropriately.

Biases in chlamydia screening may contribute to higher reported rates of chlamydia among minority and poor young women. (Read the full article)

A Parent-Led Family-Focused Treatment Program for Overweight Children Aged 5 to 9 Years: The PEACH RCT

Targeting parents only, a 10% relative weight loss is achievable in moderately obese preadolescent children and can be maintained 2 years from baseline, which justifies an investment in treatment as a secondary obesity-prevention strategy. (Read the full article)
