Several studies have shown that behavioral problems can be associated with defecation and voiding disorders, although few studies have looked directly at a link between a diagnosis of attention-deficit/hyperactivity disorder (ADHD) and constipation or fecal incontinence.

We identified an increased risk for both constipation and fecal incontinence in children with ADHD. In patients with concomitant ADHD and defecation disorders, more aggressive medical and behavioral treatment of the constipation or fecal incontinence may be warranted. (Read the full article)

Children with chronic illnesses tend to be sicker during infections than previously healthy children but are triaged in the same way, even though the validity of triage systems has not yet been evaluated in these chronically sick children.

The performance of the Manchester Triage System was lower for children with a chronic illness than for previously healthy children. Children with cardiovascular illnesses, respiratory illnesses, gastrointestinal illnesses, or other congenital or genetic defects were especially at risk of being undertriaged.

Late-onset sepsis is a frequent complication of prematurity, contributing to morbidity and mortality. Although evidence is accumulating that administration of probiotics to very preterm infants reduces necrotizing enterocolitis (NEC) and all-cause mortality, the effect on late-onset sepsis is less clear.

The probiotic combination Bifidobacterium infantis, Streptococcus thermophilus, and Bifidobacterium lactis reduced NEC in very preterm infants, but not mortality or late-onset sepsis. Probiotics may be of greatest global value in neonatal settings with high rates of NEC. (Read the full article)

Adverse effects of excess weight are likely related to both obesity severity and duration. Little is known about the contribution of adolescent weight status to development of specific comorbid conditions in adults.

Severe obesity at age 18 was independently associated with increased risk of lower extremity venous edema, walking limitation, kidney dysfunction, polycystic ovary syndrome, respiratory conditions, diabetes, and hypertension in adulthood. (Read the full article)

Broad-spectrum antibiotics are frequently used to empirically treat children hospitalized with community-acquired pneumonia despite recent national recommendations to use narrow-spectrum antibiotics.

Narrow-spectrum antibiotics are similar to broad-spectrum antibiotics for the treatment of children hospitalized with community-acquired pneumonia in terms of clinical outcomes and resource utilization. This study provides scientific evidence to support national consensus guidelines. (Read the full article)

Inconsistent results have been reported on the association between sleep duration and blood pressure (BP) in children, likely as a result of inadequate adjustment for confounders and the use of different time frames in assessing sleep duration.

Short sleep duration and poor sleep quality are associated with higher BP in normal-weight adolescents. One night of adequate sleep may partially ameliorate the risk of high BP but cannot completely reverse the effect of chronic sleep insufficiency. (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)

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)

Infant postexposure prophylaxis prevents perinatal hepatitis B (HepB) virus transmission and mortality and morbidity caused by chronic HepB virus infection. The US Perinatal Hepatitis B Prevention Program (PHBPP) identifies and manages infants born to HepB surface antigen–positive women.

It presents the first estimates of the long-term costs and outcomes of postexposure prophylaxis with the PHBPP. It analyzes the effects of the PHBPP, and alternative immunization scenarios, on health and economic outcomes for the 2009 US birth cohort. (Read the full article)

Congenital cytomegalovirus (CMV) infection is a leading cause of sensorineural hearing loss and neurodevelopmental impairment in full-term infants. The incidence of congenital CMV infection in preterm infants and the possible associations with developmental outcomes are unknown.

This study defines the incidence of congenital CMV infection in very low birth weight infants and identifies strong associations of congenital CMV infection with hearing loss and adverse neurodevelopmental outcomes in this population. (Read the full article)

Viral wheezing is common in preschool-aged children. The efficacy of inhaled steroids in preventing viral wheezing is debated. Despite this debate, nebulized beclomethasone is widely prescribed (particularly in a few countries) to children with upper respiratory tract infections.

Findings from this study confirm that inhaled steroids are not effective in preventing viral wheezing. Moreover, no differences were found in the persistence of symptoms (eg, runny nose, sore throat) or in the parental perception of asthma-like symptom severity. (Read the full article)

Maintaining high levels of measles-mumps-rubella immunization is an important public health priority that has been threatened by discredited claims about the safety of the vaccine. Relatively little is known about what messages are effective in overcoming parental reluctance to vaccinate.

Pro-vaccine messages do not always work as intended. The effectiveness of those messages may vary depending on existing parental attitudes toward vaccines. For some parents, they may actually increase misperceptions or reduce vaccination intention. (Read the full article)

Little is known about the epidemiology and pathogenicity of Clostridium difficile infection among children, particularly those aged ≤3 years in whom colonization is common and pathogenicity uncertain.

Young children, 1 to 3 years of age, had the highest Clostridium difficile infection incidence. Considering that clinical presentation, outcomes, and disease severity were similar across age groups, C difficile infection in the youngest age group likely represents true disease and not asymptomatic colonization. (Read the full article)

Young children have multiple upper respiratory infections (URI) annually. Limited health literacy regarding URI can place families at risk for emergency department (ED) visits, inappropriate use of over-the-counter medications, and medication measurement errors.

Few educational interventions for URI have targeted groups with limited health literacy. Integrating an educational intervention into Early Head Start is a novel approach to increasing parental health literacy regarding URI and decreasing ED visits, with potential for wide dissemination.

In the United States, given the high burden of disease, influenza vaccine is recommended for all children from age 6 months. The paucity of vaccine effectiveness data in children <2 years has led some to argue against routine vaccination in this age group.

This study reveals the effectiveness of trivalent influenza vaccine in young children and supports the current Advisory Committee on Immunization Practices recommendation. This study provides the strongest evidence to date confirming the effectiveness of trivalent influenza vaccine in children <2 years of age. (Read the full article)

Urinary tract infection (UTI) is the most common bacterial infection in febrile infants aged 1 to 90 days. It is unclear if urine microscopy offers significant benefit beyond urine dipstick as a screening test for UTI in this population.

Dipstick may be an adequate screening test for UTI in infants aged 1 to 90 days with a negative predictive value (NPV) of 98.7%. Adding microscopy increases the NPV to 99.2% but results in 8 false-positives for every UTI missed by dipstick. (Read the full article)

Central line–associated bloodstream infections (CLABSI) are common types of hospital-acquired infections associated with high morbidity and cost. In recent years, quality improvement initiatives have demonstrated how to reduce the incidence of CLABSI.

This study presents nationally representative estimates of the cost and length of stay attributable to pediatric CLABSI. We make the business case to justify quality improvement prevention initiatives and the adoption of strategies for cost-effective management of CLABSI. (Read the full article)

Primary HHV-7 infection is almost universal by age 5 years and is causally associated with exanthem subitum, febrile seizures, and febrile status epilepticus. The consequences of delayed primary infection are unknown, although encephalitis has been reported in one adult.

Delayed primary HHV-7 infection can cause serious neurologic disease as identified in 3 adolescents, 2 with encephalitis and 1 with Guillain-Barré syndrome. Serologic tests to distinguish primary from past HHV-7 infection are imperative when HHV-7 DNA is present in CSF. (Read the full article)

Inadequate nutrient intake can compromise a child’s nutritional status, which may affect immune function. Improving dietary intake via a follow-up formula may support appropriate immune responses and improve a child’s ability to resist infection.

Children who consumed an experimental follow-up formula had fewer episodes and shorter duration of acute respiratory infections, as well as less antibiotic treatment, and fewer days missed of day care due to illness. (Read the full article)

Studies on adult patients who have Crohn disease have shown a comparative benefit of anti-TNFα versus placebo and thiopurines. These same studies have not been done in children, because of time, cost, and ethical (withholding an efficacious treatment) challenges.

Anti-TNFα therapy administered in routine practice to children with Crohn disease was more effective than usual care at achieving clinical and corticosteroid-free remission. Using data from the ImproveCareNow learning health system for observational research is feasible and produces valuable evidence. (Read the full article)

Delayed diagnosis of critical congenital heart defects (CCHDs) is associated with increased morbidity and mortality.

Despite increasing prenatal diagnosis rates, delayed diagnosis of CCHDs continues to occur, with rates highest among isolated cases and those delivered at nontertiary care hospitals. Better understanding of delayed diagnosis could help to improve screening efforts. (Read the full article)

Lower respiratory tract infections (LRTIs), including pneumonia, are in the top 10 causes of death among children in the United States. In high-income countries, 3% to 14% of LRTI hospitalizations have been reported to require admission to an ICU.

During 2007–2011, approximately 31 289 hospitalizations for severe LRTI occurred in children each year in the United States. Children <1 year of age had the highest rates of severe LRTI and accounted for 30% of severe LRTI hospitalizations. (Read the full article)

Hydroxyurea is a treatment option for young patients with sickle cell disease (SCD). Establishing the safety of hydroxyurea is of paramount importance. The effect of hydroxyurea on immune function and immunizations in SCD has not been studied previously.

Children with SCD receiving hydroxyurea have lower lymphocyte, CD4, and memory T-cell counts compared with those receiving placebo, but still in the range for healthy children. Despite slower response to measles vaccine, measles, mumps, and rubella and pneumococcal vaccines are effective. (Read the full article)

Health care–associated infections are harmful, costly, and preventable, yet there remain limited data as to their population incidence among hospitalized neonates and children in the United States.

Incidence rates of central line–associated bloodstream infections and ventilator-associated pneumonia decreased among critically ill neonates and children during a 5-year period in the United States. National efforts to improve patient safety through decreasing HAIs have been effective. (Read the full article)

Many pediatric acute respiratory tract infections (ARTI) are viral and do not require antimicrobial treatment. Recent estimates of antimicrobial overprescribing for these infections, defined based on the published bacterial disease prevalence among all ARTI, are not available.

Based on the published bacterial prevalence rates for pediatric ARTI, antimicrobial agents are prescribed almost twice as often as expected to outpatients nationally, amounting to an estimated 11.4 million potentially preventable antimicrobial prescriptions annually. (Read the full article)

Continuously aerosolized albuterol been shown to be safe and effective for the treatment of severe status asthmaticus in the emergency department and ICU. Little evidence supports its use in the non–intensive care setting.

With the appropriate resources and support, continuous albuterol may be administered in the non–ICU setting with a low incidence of clinical deterioration and adverse effects. Certain clinical factors may help identify which patients may benefit from higher acuity care. (Read the full article)

Physical activity programs have been shown to have positive implications for children’s cognitive performance and brain structure and function. However, additional randomized controlled trials are needed to determine whether daily physical activity influences executive control and its neural underpinnings.

The randomized controlled trial, designed to meet daily physical activity recommendations, used behavioral and electrophysiological measures of brain function to demonstrate enhanced attentional inhibition and cognitive flexibility among prepubertal children. (Read the full article)

Neurodevelopment can be adversely affected by viral infections. Human herpesvirus-6 (HHV-6) is similar to cytomegalovirus and can cause central nervous system disease. Congenital HHV-6 infection occurs in ~1% of live births, with unknown neurodevelopmental consequences.

HHV-6 congenital infection is associated with lower scores on the Bayley Scales of Infant Development II Mental Development Index compared with control infants at 12 months of age and may have a detrimental effect on neurodevelopment. (Read the full article)

Menu labels depicting physical activity calorie equivalents may lead to ordering of fast food meals totaling fewer calories for adults. The effects of physical activity calorie equivalent labeling on parents’ fast food decisions for their children have not been examined.

Parents shown menus with any type of caloric content label may order fast food meals totaling fewer calories for their children. Menu labels showing physical activity equivalents may be more likely to influence parents to encourage their children to exercise. (Read the full article)

This is the first population-based study regarding the epidemiologic characteristics of pediatric zoster among only those who had contracted varicella.

The herpes zoster (HZ) incidence among only children with varicella infection is higher than previously reported. The HZ incidence increased for children contracting varicella aged <2 years. After a vaccination program, the HZ risk increased for those contracting varicella aged ≥2 years. (Read the full article)

Myxovirus resistance protein A (MxA) is a protein induced during viral infections. A few small-scale studies have suggested that MxA could be used as a marker of viral infection in clinical routine practice.

This study involves the largest patient population thus far and confirms the usefulness of MxA for diagnosing viral infections in children consulting the emergency department in a clinical routine setting. (Read the full article)

Encephalitis is a serious and disabling condition. There are infectious and immune-mediated causes of encephalitis, but many cases remain undiagnosed.

This large single-center study on childhood encephalitis provides insight into the relative frequency and clinicoradiologic phenotypes of infectious, autoantibody-associated, and unknown encephalitis. Risk factors for an abnormal outcome are also defined. (Read the full article)

Collaborative care is known to be an effective system to manage child behavioral health conditions in the primary care setting.

Among urban children with attention-deficit/hyperactivity disorder, using lay care managers to address barriers to engagement with care and challenging child behaviors has the potential to improve the effectiveness of conventional collaborative care. (Read the full article)

Timely immunoprophylaxis and completion of the 3-dose hepatitis B vaccine series represents the cornerstone of perinatal hepatitis B prevention. Immunoprophylaxis for infants born to hepatitis B surface antigen–positive mothers reduces up to 95% of perinatal hepatitis B virus infections.

Despite recommended immunoprophylaxis, perinatal hepatitis B virus infection occurs among ~1% of infants. Infants born to mothers who are younger, hepatitis B e-antigen positive, or who have a high viral load or infants who receive <3 hepatitis B vaccine doses are at greatest risk of infection. (Read the full article)

Otorrhea is common in children with tympanostomy tubes: annually, 2 of 3 children develop 1 or more episodes. Antibiotic-glucocorticoid eardrops are the most effective treatment in both the short- and long-term.

Treatment with antibiotic-glucocorticoid eardrops costs less than oral antibiotics and initial observation in children with tympanostomy tubes who develop otorrhea. Non–health care costs constitute a substantial proportion of the total costs of this condition. (Read the full article)

Although waning immunity with the childhood pertussis vaccination series has been reported, there are limited data on duration of protection of the adolescent pertussis vaccine (Tdap), especially among those who have received only acellular vaccines.

This study reports that protection from Tdap wanes substantially 2 to 4 years after vaccination among adolescents who received all acellular vaccines during childhood. This waning protection is likely contributing to the increase in adolescent pertussis. (Read the full article)

Newborn screening for critical congenital heart defects (CCHDs) has been implemented in many hospitals, yet there is uncertainty about the number of infants with CCHDs that might be detected through universal implementation of newborn CCHD screening in the United States.

We estimated that ~875 infants with CCHDs might be detected, and ~880 missed, annually through universal CCHD screening in the United States. Increases in prenatal diagnosis are unlikely to substantially impact the number of infants detected through CCHD screening. (Read the full article)

Concussion produces a range of symptoms that may impede academic functioning. The need for empirical validation exists, despite growing consensus on the importance of a guided return-to-school process for students recovering from concussion.

This study provides initial evidence of a concussion’s adverse effects on academic learning and performance across all grades, including heightened levels of school-related concern and amplified postinjury academic difficulties experienced by symptomatic students relative to their recovered peers.

The sensitivity of the urinalysis (UA) traditionally has been considered suboptimal in young infants. Whether the finding of a negative UA and a positive urine culture represents a false-negative UA versus a false-positive urine culture remains unclear.

In infants <3 months with bacteremic urinary tract infection, a condition that represents true infection, the UA sensitivity is higher than previously reported for urinary tract infection in general, suggesting that the UA is reliable even in young infants. (Read the full article)

Vesicoureteral reflux is recognized as an important risk factor for recurrent urinary tract infection and renal scarring. Less is known about the contribution of other risk factors to these outcomes.

This study found that information about vesicoureteral reflux and bladder and bowel dysfunction can be used to identify children at low, medium, and high risk of recurrent urinary tract infection, information that clinicians could use to select children for specific preventive therapies. (Read the full article)

The US Preventive Services Task Force recommends primary care clinicians apply fluoride varnish to the teeth of all young children, but no studies have examined the effect of comprehensive preventive oral health services on children’s clinical oral health status.

Comprehensive preventive oral health services delivered by primary care clinicians can help improve the oral health of Medicaid-enrolled children, but more work is needed to link medical and dental offices to ensure the continuity of dental care for these children. (Read the full article)

War-affected youth often suffer from multiple co-occurring mental health problems. The relationship of these conditions to later mental health has yet to be thoroughly investigated. There is a need to explore potential targets for mental health interventions.

After controlling for preexisting conditions and contemporary confounders, internalizing (depression and anxiety) remained the major predictor of future mental health symptoms (internalizing symptoms, prosocial attitudes/behaviors, and posttraumatic stress symptoms). Interventions targeting internalizing in war-affected youth hold promise. (Read the full article)

Biotinidase deficiency (BD) might cause severe and permanent consequences. Cases detected through newborn screening and under treatment are shown to remain asymptomatic. However, some countries, including Spain, do not provide universal BD screening within their national newborn screening programs.

It provides a first estimate of the lifetime costs and health outcomes of a Spanish birth cohort with and without neonatal screening for BD. It shows that newborn screening for BD is likely to be a cost-effective use of resources. (Read the full article)

In adults, there is significant increased length of stay, cost, and/or resource use associated with hospital-acquired conditions. Less is known about the epidemiology and impact of many hospital-acquired conditions in pediatric populations.

We find increased pediatric length of stay and costs due to venous thromboembolism and catheter-associated urinary tract infections. This is essential information for hospital administrators and safety departments who are planning interventions to reduce harm associated with these hospital-acquired conditions.

Poor neurocognitive outcomes are associated with some types of congenital heart defects (CHDs). Guidelines for developmental screening for children with CHDs have been published. Population-based information on special education services needed among children with CHDs is limited.

Children in metropolitan Atlanta with congenital heart defects (CHDs) received special education services more often than children without birth defects. These findings highlight the need for special education services and the importance of developmental screening for all children with CHDs. (Read the full article)

Childhood inflammatory mediators are associated with adult obesity, but the stimuli that initiate and perpetuate chronic inflammation start in early life are largely unknown.

Childhood infection-related hospitalization was independently associated with adverse adult metabolic variables, which suggests that infections and/or their treatment in childhood may contribute to causal pathways leading to adult cardiometabolic diseases. (Read the full article)

Congenital cytomegalovirus infection is the leading infectious cause of neurologic disabilities and sensorineural hearing loss in children. Little is known concerning the frequency and impact of vestibular disorders induced by cytomegalovirus infection.

This study reports on the largest cohort of vestibular assessment of children congenitally infected with cytomegalovirus, demonstrating vestibular damages, and analyzes the correlations between vestibular dysfunction and hearing impairment or severity of infection. Cytomegalovirus infection affects postural development in children. (Read the full article)

The source of infant pertussis infection is typically identified ~50% of the time. Historically, mothers have been identified as the most common source of pertussis transmission to infants.

This analysis of 8 years of enhanced pertussis surveillance data has uncovered a shift in the most common source of infant pertussis infection in the United States from mothers to siblings. (Read the full article)

Sleep disturbances in infants associate with individual differences in temperament. However, little is known about interindividual differences and potential moderating factors, such as genotype.

The results suggest that the cumulative effect of total sleep duration during the first 3 years of life on temperament is moderated by child 5-HTTLPR genotype following a differential susceptibility model. (Read the full article)

Adolescent vaccination rates lag behind other childhood vaccines. Text messaging to improve uptake of adolescent vaccines has been shown to be effective in academic centers but has not been studied in other settings.

This study, done in 5 private and 2 safety-net practices, used a bidirectional text message as a behavioral prompt and showed text messaging was effective at increasing uptake of all adolescent vaccines. Costs were similar to other reminder/recall methods. (Read the full article)
