Attention-deficit/hyperactivity disorder (ADHD) is the most common mental health condition diagnosed in childhood, is highly heritable, and more common in boys. Although studies have identified perinatal risk factors, no one has investigated perinatal risk factors separately in boys and girls.

Contrary to other studies, low birth weight, postterm pregnancy, low Apgar scores, and fetal distress were not risk factors for ADHD irrespective of gender. Early term deliveries increased the risk of ADHD, and oxytocin augmentation in girls may be protective. (Read the full article)

The demand for donor kidneys for transplantation exceeds supply. En bloc kidney transplantation and donation after determination of circulatory death from pediatric donors increases the potential donor pool.

Newborn infants undergoing elective withdrawal of life support in the NICU are a previously unrecognized source of potential kidney donors. (Read the full article)

Youth are frequent consumers of movies that contain high levels of violence, and violent content in films, especially those rated PG-13, has been increasing over time.

Content analyses seldom examine how violence is portrayed with other health risk behaviors, such smoking, drinking, and sex. This study presents an innovative way to characterize on-screen violent content and demonstrates the extent to which risk behaviors co-occur within films. (Read the full article)

Hypertonic saline (3% and 5%), has been shown to improve clinical severity scores and reduce inpatient length of stay, and was associated with a trend toward lower admission rate in acute bronchiolitis.

We are not aware of any previous data using 7% hypertonic saline in bronchiolitis. Our results suggest that 7% saline does not lower clinical severity of illness, admission rate, or length of stay, when compared with normal saline. (Read the full article)

The incidence of pertussis has significantly increased, and infection can result in severe disease among young children. This highly contagious disease may frequently be transmitted in pediatric health care settings, necessitating effective infection control practices to reduce exposure risk.

Despite institutional guidelines, pediatric health care workers (HCWs) are frequently exposed to pertussis because of delayed or incomplete adherence to infection control practices. Inconsistent reporting may also result in missed HCW exposures, increasing the risk of subsequent transmission to patients. (Read the full article)

Studies assessing the accuracy of brief screening tools for postpartum depression have been conducted among adult women; however, no similar validation studies have been conducted among adolescent mothers. Accurate and valid brief depression screening tools are needed for adolescent mothers.

We found that the 10-item Edinburgh Postnatal Depression Scale (EPDS) and 2 subscales, the EPDS-7 and EPDS-2, are highly accurate at identifying postpartum depression among adolescent mothers. In pediatric settings with limited time and resources, these brief scales have potential to be used as effective depression screening tools. (Read the full article)

Screening for autism spectrum disorders (ASDs) using the Modified Checklist for Autism in Toddlers (M-CHAT) improves early detection and long-term prognosis of ASD. Reducing the false-positive rate may increase implementation of screening for ASDs.

The Modified Checklist for Autism in Toddlers, Revised with Follow-up (M-CHAT-R/F), simplifies wording of the original M-CHAT. The current validation study indicates that the M-CHAT-R/F improves the ability to detect autism spectrum disorders in toddlers screened during well-child care visits. (Read the full article)

Currently, the false-positive rate of appendicitis in children is ≤5%. Abdominal imaging and blood tests (particularly leukocytosis) help minimize the negative appendectomy rate, but appendicitis is not always associated with an elevated white blood cell count.

Reducing the threshold of leukocytosis as a criterion for appendicitis to 8000 to 9000 white blood cells per µL improves specificity (negative appendectomy: <1%) while only marginally decreasing sensitivity. (Read the full article)

Bacille Calmette-Guerin (BCG) vaccination may provide benefits beyond protecting against pediatric tuberculosis. Evidence suggests links between cell-mediated immunity from tuberculosis and bacterial/viral-related pneumonia but the impact of BCG on acute lower respiratory infection is not fully known.

BCG-vaccinated children had a lower risk of suspected acute lower respiratory infection. Protection was amplified when children were vaccinated against diphtheria-tetanus-pertussis (DTP). Number of DTP doses did not modify this effect, but order in which vaccines were received did. (Read the full article)

Systematic health disparities in adults with systemic lupus erythematosus are well documented and are likely driven by biologic as well as modifiable factors. Sociodemographic factors and health care delivery characteristics have been associated with poor outcomes.

In hospitalized children with systemic lupus erythematosus, race and ethnicity were associated with increased risk for ICU admissions, end-stage renal disease, and death. Identification of sociodemographic factors associated with outcomes is important to address the needs of these vulnerable patients. (Read the full article)

Xylitol given as a gum or syrup 5 times daily has been shown to reduce the incidence of acute otitis media in children, but this dosing schedule is unlikely to be feasible for many families.

A regimen of viscous xylitol syrup in a dose of 5 g 3 times daily was ineffective in preventing recurrences of acute otitis media in otitis-prone children. (Read the full article)

Due to reports of unintentional overdoses, in 2011 the US Food and Drug Administration finalized voluntary recommendations for dosing devices included with over-the-counter (OTC) liquid medications. The Consumer Healthcare Products Association previously endorsed similar recommendations for devices and dosing directions.

This study assessed dosing directions and devices for national brand name OTC liquid medications, available after a voluntary FDA guidance, and found high levels of adherence to most recommendations. Further improvement efforts should prioritize recommendations directly addressing potential dosing errors. (Read the full article)

Cognitive rest is recommended for the management of sport-related concussions. There are limited data to support this recommendation.

This study adds empirical data supporting the recommendation for cognitive rest after a sport-related concussion. (Read the full article)

Childhood obesity poses a serious threat to human health. Obesity is caused by genetic and environmental factors and linked to type 2 diabetes and cardiovascular disease. Pediatric obesity cohorts aim at understanding early events in the pathophysiology of obesity-related complications.

Cohort subjects are examined at consecutive visits, including measurements of glucose tolerance and hormones regulating nutrient handling (enhanced glucose tolerance tests) and body composition (MRI and bioimpedance). Mechanisms causing obese children to progress to type 2 diabetes are delineated. (Read the full article)

There is a perception that Gram-negative bacilli (GNB) bloodstream infection is increasing in the NICU, and those infections caused by a multidrug-resistant (MDR) strain are a growing threat to hospitalized patients.

Exposure to broad-spectrum antibiotics is the most important risk factor for MDR GNB bacteremia, which is associated with higher mortality. Neonates with risk factors for bacteremia caused by a MDR GNB strain may benefit from empirical antimicrobial therapy with carbapenem. (Read the full article)

Age-appropriate child safety seat use in the United States is suboptimal, particularly among children older than 1 year. Minority children have higher rates of inappropriate child safety seat use based on observational studies. Explanations for observed differences include socioeconomic factors.

White parents reported greater use of age-appropriate child safety seats for 1- to 7-year-old children than nonwhite parents. Race remained a significant predictor of age-appropriate restraint use after adjusting for parental education, family income, and information sources. (Read the full article)

Celiac disease (CD) often goes undiagnosed. Current guidelines suggest intensified active case-finding, with liberal testing of children with CD-associated symptoms and/or conditions. However, methods for also finding undiagnosed CD cases in the general population should be explored and evaluated.

In a population-based CD screening, information on CD-associated symptoms and conditions, obtained before knowledge of CD status, was not useful in discriminating undiagnosed CD cases from non-CD children. The majority of screening-detected CD cases had no CD-associated symptoms or conditions. (Read the full article)

Tonsillectomy is one of the most commonly performed surgeries in children and is one of the most cumulatively expensive conditions in pediatric hospital care. Little is known about how the quality of tonsillectomy care varies across hospitals.

In a large cohort of low-risk children undergoing same-day tonsillectomy, there was substantial variation in quality measures of process, dexamethasone and antibiotic use, and outcome, revisits to the hospital within the first 30 days after surgery. (Read the full article)

Biomarkers such as C-reactive protein (CRP) and procalcitonin are elevated in children with severe bacterial infections. Children with severe malnutrition are at increased risk of bacterial infections and early markers for the diagnosis of infection in these children are needed.

Despite elevated values in severely malnourished children with invasive bacterial infection or infectious diarrhea, CRP and procalcitonin have limited diagnostic value. CRP could predict death in these children with a good negative predictive value. (Read the full article)

Firearm injuries are the second leading cause of death among American children. Previous estimates of nonfatal injuries have relied on small samples of emergency department visits and do not allow a detailed understanding of these injuries among children and adolescents.

In 2009, there were 7391 hospitalizations for firearm-related injuries in US children and adolescents; 89% of hospitalizations occurred in males. Hospitalization rates were highest for 15- to 19-year-olds and for black males. Deaths in the hospital occurred in 6.1% of children and adolescents. (Read the full article)

The Centers for Disease Control and FITNESSGRAM BMI percentile thresholds are commonly used for obesity screening in youth. It is assumed that these thresholds are predictive of metabolic health risk, but little diagnostic data are available.

Both thresholds are predictive of metabolic syndrome, more so for boys than for girls, although with differing sensitivity and specificity. The diagnostic details of the thresholds can inform clinicians and practitioners about how these standards perform in practice. (Read the full article)

In preterm infants receiving supplemental oxygen, manual control of the inspired oxygen fraction is often difficult and time consuming, which may increase the risk of complications. We developed a system for automatic oxygen control and proved its efficacy in the past.

A multicenter study adds evidence for the proposed automatic oxygen control system to significantly improve oxygen administration to preterm infants receiving mechanical ventilation or nasal continuous positive airway pressure while reducing workload compared with routine manual oxygen control.

Current guidelines recommend renal ultrasound as a screening test after febrile urinary tract infection, with voiding cystourethrogram (VCUG) only if the ultrasound is abnormal. Few studies have evaluated the accuracy of ultrasound as a screening test for VCUG-identified abnormalities.

This study shows that ultrasound is a poor screening test for genitourinary abnormalities identified on VCUG, such as vesicoureteral reflux. Neither positive nor negative ultrasounds reliably identify or rule out such abnormalities. Ultrasound and VCUG provide different, but complementary, information. (Read the full article)

In children with congenital toxoplasmosis, ocular lesions can be detected and may relapse after birth despite pre- and postnatal treatment. Long-term ocular outcome beyond puberty and associated prognostic factors are unknown due to limited follow-up.

Our study in 477 patients with treated congenital toxoplasmosis who were followed up to 22 years indicated that new ocular lesions can be detected well into adolescence (with a cumulative probability at 18 years of almost 50%), but they rarely cause severe visual impairment.

Encephalitis in children can cause significant neurologic sequelae, such as motor and cognitive impairment. Previous reported data are based mostly on questionnaires and clinical assessments.

Significant cognitive impairment, attention-deficit/hyperactivity disorder, and learning disabilities are common after childhood encephalitis. Even children who were considered fully recovered may be significantly affected. Identifiable pathogens, abnormal neuroimaging, and abnormal neurologic examination on discharge are risk factors of poor outcome. (Read the full article)

Preterm (PT) birth is negatively associated with growth. Particularly small for gestational age PT infants are at risk for delays in growth, whereas knowledge about the consequences regarding growth of large for gestational age PT birth is lacking.

During infancy, growth in height, weight, and head circumference of large for gestational age PT infants was well balanced and sufficient. Subsequently, however, weight gain accelerated and resulted in high BMIs compared with the World Health Organization Multicentre Growth Reference Study population. (Read the full article)

Quantitative real-time polymerase chain reaction allows sensitive detection of respiratory viruses. The clinical significance of detection of specific viruses is not fully understood, however, and several viruses have been detected in the respiratory tract of asymptomatic children.

Our results indicate that quantitative real-time polymerase chain reaction is limited at distinguishing acute infection from detection in asymptomatic children for rhinovirus, bocavirus, adenovirus, enterovirus, and coronavirus. (Read the full article)

After mild traumatic brain injury, most youth recover well. A minority of patients report persistent symptoms, which relate to both injury and noninjury factors. In adult studies, validity test performance is 1 noninjury factor that relates to persistent symptoms.

This is the first pediatric study to demonstrate that validity test failure is associated with increased symptoms after mild traumatic brain injury. The findings suggest that some symptoms conceptualized as injury-related "postconcussive" problems are better explained by exaggeration or feigning. (Read the full article)

Concussions in youth are a common injury evaluated in the emergency department (ED). Early recognition and active management of this mild traumatic brain injury are important to safe recovery. Tools to assess and manage concussion in the ED are lacking.

Acute Concussion Evaluation tools, modified for ED use, improved reported follow-up with primary care or concussion specialists and adherence to recommendations. Barriers to follow-up remain and the importance of ongoing outpatient management should be stressed. (Read the full article)

Diarrhea still remains as a significant cause of morbidity and mortality. Intervention to reduce this risk are needed. Evidence on the effect of Lactobacillus reuteri DSM 17938 to prevent diarrhea in children is scarce.

In healthy children attending day care centers, daily administration of L reuteri DSM 17938 had a significant effect in reducing episodes and duration of diarrhea and respiratory tract infections, with consequent cost saving for the community. (Read the full article)

Approximately 50% of children diagnosed with attention-deficit/hyperactivity disorder (ADHD) at <7 years of age in the community do not meet criteria for ADHD over time. There is a need to examine predictors of diagnostic stability in young children with ADHD.

Predictors of diagnostic stability from early to middle childhood include child’s baseline externalizing and internalizing symptoms, parental history of psychopathology, and socioeconomic status. These predictors may guide treatment planning at the time of ADHD diagnosis. (Read the full article)

Childhood attention-deficit/hyperactivity disorder has been associated with both childhood and adult obesity, whereas treatment with stimulants has been associated with delayed child growth. No longitudinal studies with details about dates of diagnosis, treatment, and duration of stimulant use have been published.

Using electronic health record data, this was the first study to evaluate the independent associations of attention-deficit/hyperactivity disorder diagnosis, stimulant treatment, age at first stimulant use, and duration of stimulant use on longitudinal BMI trajectories throughout childhood and adolescence.

The period of transition from childhood to adulthood and the period immediately after transfer of care is a challenging time for young people with kidney failure.

Young patients with kidney failure cared for exclusively in adult-oriented facilities experience increased rates of avoidable hospitalizations during late adolescence and young adulthood. Avoidable hospitalizations increased among pediatric kidney failure patients during the years immediately after transfer to adult care. (Read the full article)

Diabetic ketoacidosis (DKA) is a life-threatening condition and often the presenting symptom of newly diagnosed type 1 or type 2 diabetes in youth. SEARCH previously reported that the prevalence of DKA at diagnosis was 25.5% in 2002–2003.

DKA in youth with type 1 diabetes remains a problem, with almost one-third presenting with DKA. Among youth with type 2 diabetes, DKA was less common and decreased by ~10% per year, suggesting improved detection or earlier diagnosis. (Read the full article)

Many studies have demonstrated that the built environment is related to both collision risk and walking to school. However, little research examines the influence of the built environment on the relationship between walking to school and pedestrian collision risk.

Increased walking was not associated with increased pedestrian collision once the effects of the built environment and socioeconomic status were modeled. Safety was related primarily to the built environment and specifically features related to road crossing. (Read the full article)

One in 4 children with cerebral palsy (CP) have a behavioral disorder. Parenting interventions are an efficacious approach to treating behavioral disorders. There is a paucity of research on parenting interventions with families of children with CP.

This is the first study to demonstrate the efficacy of a parenting intervention in targeting behavioral problems in children with CP. Further, results suggest that Acceptance and Commitment Therapy delivers additive benefits above and beyond established parenting interventions. (Read the full article)

There is growing understanding of the detrimental effect of paternal depression on children. The transition to fatherhood is a unique time for men. Identifying which fathers are at-risk and when will inform effective methods to help men and their families.

Nonresident fathers have the highest depression symptom scores, peaking before entering fatherhood. Although resident fathers’ scores decrease preceding entry into fatherhood, there is a significant increase from 0 to 5 years of their child’s life when key parent–infant attachment occurs.

Inadequate sleep in childhood is associated with poor mental and physical health. Numerous cross-sectional studies reveal associations between television viewing and the presence of a bedroom TV and inadequate sleep in older children and adolescents, but longitudinal research is limited.

More TV viewing, and, among racial/ethnic minority children, bedroom TV, were associated with shorter sleep from infancy to midchildhood. These results raise the possibility that interventions to reduce TV could improve children’s sleep. (Read the full article)

The widely disseminated National Institute on Alcohol Abuse and Alcoholism screening tool for adolescent alcohol use was developed based on epidemiologic data. It has not been validated in a clinical sample and does not screen for tobacco or drug use.

This study found that a measure that expanded the National Institute on Alcohol Abuse and Alcoholism adolescent alcohol use tool to include tobacco and drugs was sensitive and specific for identifying substance use disorders in a pediatric clinic patient population. (Read the full article)

Early establishment of a dental home is critical for addressing the "silent epidemic" of early childhood caries. Physicians and dentists have worked to improve children’s access to dental care, but little is known about caregivers’ role in this context.

Addressing factors that affect the establishment of a child’s dental home, such as caregivers’ dental neglect and problem-driven care-seeking behaviors, is essential. Caregiver engagement seems to be pivotal for increasing use of preventive services while decreasing episodic and problem-initiated care. (Read the full article)

Early preventive dental care is cost-effective and can reduce subsequent restorative or emergency visits. Little is known about the factors distinguishing families who receive dental care in early childhood and those who do not.

Our results suggest that among healthy children seen by primary care providers, those most in need of dental care are least likely to receive it. This highlights the importance of promoting early preventive dental care in the primary care setting. (Read the full article)

Down syndrome is an independent risk factor for severe respiratory syncytial virus infection and subsequent hospitalization.

This observational study suggests that immunoprophylaxis may reduce respiratory syncytial virus-related hospitalization by 3.6-fold (95% confidence interval, 1.5–8.7) in children with Down syndrome overall. (Read the full article)

Children receive only half of recommended health care; disadvantaged children have higher risk of unmet needs. Practice coaching combined with quality improvement using rapid-cycle feedback has potential to help practices meet quality standards and improve pediatric health care delivery.

The Practice-tailored Facilitation Intervention led to large and sustained improvements in preventive service delivery, including substantial numbers of disadvantaged children, and in multiple simultaneous health care domains. Practice-tailored facilitation holds promise as a method to advance pediatric preventive care delivery. (Read the full article)

Although there has been increasing research into the effects of concussion on the developing brain in recent years, little is known about the expected duration and clinical course of individual post-concussive symptoms in children.

Children and adolescents have a significant burden of disease after concussion, with typical patients experiencing physical effects such as headache immediately after the injury, emotional symptoms later in the recovery period, and cognitive symptoms that may be present throughout.

Type 2 diabetes mellitus is one of the fastest growing pediatric chronic illnesses worldwide and disproportionately affects indigenous people from all continents.

These data support the growing body of evidence that peer mentoring is an attractive strategy for teaching health behaviors and improving health outcomes in children. (Read the full article)

It is well-established that parental smoking is associated with adolescent smoking initiation and regular tobacco use. However, we know less about how exposure to specific types of parental smoking affect adolescent smoking and progression to regular smoking in young adulthood.

Among adolescents with parents who are nicotine dependent, each previous year of parental smoking increases the likelihood they will be in a heavy smoking trajectory. Parental smoking cessation early in their children’s life is critical to prevent smoking in families. (Read the full article)

Cotinine assays for dried blood spots have been developed but not deployed in a large sample of newborn specimens.

Cotinine levels consistent with active maternal smoking were detectable in 12% of newborn blood spots, although 41% of the mothers reportedly did not smoke. Data confirm that reported smoking during pregnancy is an imperfect measure of prenatal tobacco smoke exposure. (Read the full article)

Although a number of randomized controlled trials of erythropoietin administration to preterm infants have been performed, few studies have reported 2-year or longer neurodevelopmental outcomes, and no studies have evaluated neurodevelopmental outcomes of infants randomized to receive Darbepoetin.

This is the first prospectively designed study to evaluate the neurocognitive outcomes of preterm infants randomized to receive Darbepoetin or erythropoietin compared with placebo. Infants in the ESA groups had significantly higher cognitive scores compared with the placebo group. (Read the full article)

Quality measures developed by the Pediatric Quality Measures Program are required to assess disparities in performance according to special health care need status. Methods are needed to identify children according to level of medical complexity in administrative data.

The Pediatric Medical Complexity Algorithm is a new, publicly available algorithm that identifies the small proportion of children with complex chronic disease in Medicaid claims and hospital discharge data with good sensitivity and good to excellent specificity. (Read the full article)
