Up to 50% of children with attention-deficit/hyperactivity disorder (ADHD) meet criteria for a comorbid anxiety disorder. Despite the high prevalence of anxiety in these children, the impact of anxiety on the lives of children with ADHD has been largely overlooked.

Presence of ≥2 anxiety comorbidities in children with ADHD was associated with poorer child quality of life, daily functioning, and behavior. Multiple anxiety comorbidities were associated with poorer functioning for children with both ADHD-Inattentive and ADHD-Combined presentation. (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)

Adolescents with chronic disease are a diverse population with common needs for transition. Disease-specific interventions have shown promise at improving patient outcomes but with substantial personnel and resource costs. Whether a generic approach across diseases may be useful is unknown.

This study is among the first to evaluate a generic (across disease) approach to transition of adolescents to adult care. The approach demonstrated promise and cost savings due to reduced personnel requirement and use of low-cost technology dissemination methods. (Read the full article)

A limited number of studies have identified distinct patterns of child sleep duration, which appear to have implications for health and well-being.

This article identifies distinct patterns of sleep duration during early childhood and demonstrates that these have important implications for health-related quality of life. (Read the full article)

Parents in disadvantaged households are less likely to book share with their children during early childhood. These children are more likely to enter school with delays in emergent literacy and language skills, apparent as early as the age of 3.

This study examines the effect of parental immigrant status as a predictor of reading and sharing books with children. This research disentangles immigrant status from other variables thought to explain disparities in familial practices related to emergent literacy. (Read the full article)

Poor health in children is associated with exposure to family violence and disruption. Telomere length has been hypothesized to be a lasting biological indicator of exposure to early adversity and potentially predictive of negative health outcomes throughout the life course.

Telomere length reflects exposure to family violence and disruption and may be an early indicator of the biological impact of early adversity. Children exposed to interpersonal violence and family disruptions had significantly shorter telomeres. Gender moderated these associations. (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)

Autism prevalence is reported to be highest among non-Hispanic white children, lower in Hispanic and African American/black children, and highly variable in Asian/Pacific Islanders. More comorbid intellectual disability and delays in expressive language have been observed among Hispanic and African American children.

Maternal nativity is a risk factor for childhood autism in US populations. We observed higher risk of severe autism phenotypes in children of foreign-born black, Central/South American, Filipino, and Vietnamese mothers and US-born African Americans and Hispanics compared with US-born whites.

Early referral of infants with critical congenital heart disease (CCHD) is recommended to reduce mortality. However, few population-based data have been published showing the relationship between CCHD neonatal mortality and timing of cardiac evaluation at a specialty center.

In neonates with CCHD, 35% were not evaluated at a cardiac center by 4 days of age. These cases accounted for a significant number of CCHD deaths. This information enhances the rationale for pulse oximetry screening of neonates for CCHD. (Read the full article)

Invasive pneumococcal disease causes enormous morbidity in children. The spectrum and severity of illness caused by pneumococcal serotypes not present in the current vaccine, and whether the clinical profile and severity of disease have changed, are largely unknown.

Initial data suggest that nonvaccine serotypes are more common in children with underlying conditions, who have greater morbidity from disease. In the post-PCV13 era, a larger proportion of patients are hospitalized, but mortality rates are unchanged. (Read the full article)

Sleep disturbance affects 47% to 60% of children with atopic dermatitis and is a leading cause of impaired quality of life for the patients and their family.

Sleep disturbance in children with atopic dermatitis can be predicted by a Scoring Atopic Dermatitis index of ≥48.7, and lower nocturnal melatonin secretion might play a role in the pathophysiology. (Read the full article)

Mothers of children with neurodevelopmental disabilities often experience poor health, high stress, anxiety, and depression. Highly stressed parents are less effective in their parenting roles, risking their children's developmental progress.

Evidence-based interventions in mindfulness and positive psychology significantly reduce distress in mothers of children with disabilities. Well-trained peer-mentors are effective interventionists. Adult-oriented services are needed for these mothers to improve their mental health and sustain their caregiving over the long-term. (Read the full article)

XY disorders of sex development have a diverse etiology and often present with atypical genitalia in the newborn period. Sex assignment in those cases in whom this is marked genital ambiguity is a rare, challenging situation that requires multidisciplinary input.

An international registry has shown temporal changes over the last 3 decades in the practice of sex assignment with a greater proportion of severely affected infants being raised as boys, raising the need for long-term monitoring of these children. (Read the full article)

Arthropod-borne viruses are important causes of neurologic infections among children in the United States. The epidemiology of these diseases is complex and relates to multiple factors, including vector biology, animal reservoirs, weather, and human behavior.

National surveillance data from 2003 to 2012 will improve understanding of the geographic, temporal, and clinical trends in pediatric neuroinvasive arboviral disease, and will inform decision-making for clinicians, public health authorities, and the general public. (Read the full article)

The prevalence of disability in childhood has been on the rise for the past several decades. Children living in poverty are more likely to have chronic health conditions and experience disabilities.

The percentage of children with disabilities rose 16% between 2001 and 2011. Economically disadvantaged children had the highest rates of disability, but economically advantaged children experienced greater increases in disability. Disability due to neurodevelopmental or mental health conditions rose substantially. (Read the full article)

Exposure to second-hand tobacco smoke during pregnancy and infancy has been linked to development of asthma, rhinitis, and eczema in young children. It is unclear whether these risks persist into adolescence.

Exposure to second-hand smoke in utero or during infancy influences the development of allergic disease up to adolescence. Excess risks for asthma and rhinitis were seen primarily in early childhood, whereas those for eczema occurred at later ages. (Read the full article)

Recent case reports have described acute life-threatening complications in adolescents who present to health services having lost large amounts of weight but who are not underweight. Little is known about the frequency of life-threatening complications in these adolescents.

Over 6 years, we found more than a fivefold increase in the incidence of hospitalized adolescents who, apart from not being underweight, have diagnostic features of anorexia nervosa. This group experienced a similar profile of acute complications of anorexia nervosa. (Read the full article)

Growth impairment in sickle disease has been a consistent finding in published reports. Hydroxyurea (HU) decreases vasoocclusive events and increases hemoglobin levels, which may improve growth. However, HU may adversely affect growth in young children by its effect on DNA synthesis.

Height, weight, and head circumference were normal in HU-treated children in the study as compared with the World Health Organization standards. Height, weight, and BMI z scores were similar in placebo and treatment groups. There were no harmful effects of HU on growth. (Read the full article)

Asymptomatic neonatal subdural hemorrhage (SDH) is common, resolves within 4 weeks, and is typically infratentorial or posterior when supratentorial. Subdural hemorrhages may occur after cardiac surgery in infancy. Some hypothesize a causal relationship between hypoxia and SDH in infancy.

Asymptomatic neonatal SDH is often supratentorial and over the convexities. Small infratentorial SDHs may persist for ≤90 days. In young infants with congenital heart disease, an association between hypoxia and SDH could not be demonstrated. (Read the full article)

Sleep disorders are common in children and adolescents and have a substantial negative impact on daily life and school performance. Long-term evaluations of the efficacy and safety of pharmacologic treatment options for sleep disorders are lacking in pediatric patients.

These 2 studies provide the first evaluation of the effectiveness and safety of eszopiclone in children and adolescents with insomnia associated with ADHD. Data presented here encompass longer-term (up to 1 year) pediatric exposure to eszopiclone. (Read the full article)

The detection of critical congenital heart disease by fetal echocardiography or neonatal physical examination can have limitations. The addition of pulse oximetry screening in the newborn nursery increases the rate of diagnosis of these conditions before hospital discharge.

In a tertiary-care center with comprehensive fetal echocardiography, nearly all newborns with critical congenital heart disease are diagnosed prenatally. Pulse oximetry will identify more infants from settings with lower prenatal detection. Improving access to and training in fetal echocardiography should also improve detection of these conditions.

Most studies of fetal alcohol syndrome and fetal alcohol spectrum disorders (FASD) prevalence in the general population of the United States have been carried out using passive methods (surveillance or clinic-based studies), which underestimate rates of FASD.

Using active case ascertainment methods among children in a representative middle class community, rates of fetal alcohol syndrome and total FASD are found to be substantially higher than most often cited estimates for the general US population. (Read the full article)

Children who suffer abusive head trauma (AHT) have lasting health and development problems. AHT can reduce life expectancy dramatically. AHT’s contribution to the burden of disease has been estimated only as part of a broad category of intentional injury.

The DALY burden of a severe AHT case averages 80% of the burden of death, with most survivors dying before age 21 years. Even mild AHT is extremely serious, with lasting sequelae that exceed the DALY burden of a severe burn. (Read the full article)

Primary ciliary dyskinesia presents in infancy with unexplained neonatal respiratory distress, yet diagnosis is often delayed until late childhood. Earlier diagnosis facilitates earlier onset of therapy, which may help to reduce long-term pulmonary morbidity and mortality.

A diagnostic workup for primary ciliary dyskinesia should be considered in a term infant presenting with unexplained respiratory distress and either lobar collapse, situs inversus, or a prolonged oxygen therapy requirement (>2 days). (Read the full article)

Cesarean delivery has previously been associated with increased risk of specific immune diseases in children. The mechanism remains unknown.

In 1 large population-based cohort, we demonstrate cesarean delivery as a shared risk factor for several immune-related diseases. Such common risk factor suggests early life commonality in the origins of these chronic immune disorders. (Read the full article)

Studies examining early postnatal discharge and readmission for jaundice report conflicting results. Infants born 37 to 38 weeks’ gestation have an increased risk for readmission for jaundice; however, the impact of early discharge on this group has not been investigated.

Early postnatal discharge was significantly associated with readmission for jaundice. Of the infants discharged early, those born 37 to 38 weeks’ gestation, born via vaginal delivery, born to Asian mothers, or were breastfed had the greatest risk for readmission. (Read the full article)

Uptake of rotavirus vaccines has increased steadily since introduction. Despite their demonstrated impact, rotavirus vaccine coverage is lower than for other vaccines recommended in infancy and disease continues to occur.

We observed higher rotavirus detection rates among patients from provider locations with lower rotavirus vaccine coverage; providers who do not offer rotavirus vaccine to age-eligible children may create pockets of susceptible children that serve as reservoirs of ongoing disease transmission.

Meningococcal disease is a serious but rare infectious disease. In 2012, the incidence of meningococcal disease was at a historic low in the United States; however, incidence remained highest among infants aged <1 year.

This report describes the epidemiology and burden of meningococcal disease in infants aged <1 year in the United States and potential risk factors for transmission to this vulnerable group. These data are key to informing future meningococcal disease vaccination strategies. (Read the full article)

Both early and late introduction to gluten has been associated with increased risk for celiac disease (CD) and being breastfed at time of gluten introduction has been associated with a lower risk for CD.

In this prospective multinational study, time to first introduction to gluten-containing cereals is not an independent risk factor for developing CD, by a 5-year follow-up, neither on an overall level nor on country-level comparison. (Read the full article)

In most previous studies, transcutaneous bilirubin measurement has been found to provide an accurate estimate of total serum bilirubin levels. However, most of these studies were conducted in settings that optimized accuracy.

This study provides a "real-world" assessment of the accuracy of transcutaneous bilirubin measurements in multiple clinical settings and identification of sources of discrepancy between transcutaneous and total serum bilirubin measurements. (Read the full article)

Universal use of conjugated pneumococcal vaccines has resulted in dramatic decline in vaccine-type invasive pneumococcal disease. However, disease is not evenly distributed, and children with underlying clinical conditions are disproportionately represented, especially among children >5 years of age.

Invasive pneumococcal disease among children with comorbidity results in higher morbidity and mortality, and a large proportion of disease is due to serotypes not included in current conjugate vaccines. (Read the full article)

Patients with sickle cell disease frequently express dissatisfaction with emergency department treatment of painful crises. Time to opioid administration has been suggested as a quality of care measure for painful crises.

Although not associated with hospital admission, time to opioid administration in sickle cell disease painful crises was associated with secondary outcomes including improvement between the first 2 pain scores, decreased pain score area under the curve at 4 hours, decreased emergency department length of stay, and increased total opioids.

Previous studies have demonstrated racial and ethnic differences in glycemic control even after adjustment for variables such as insulin dosage, diabetes duration, and socioeconomic status. It is controversial whether genetic, physiologic, cultural, socioeconomic, and/or provider-related factors underlie these disparities.

This study in a large, racially/ethnically diverse sample of children with type 1 diabetes demonstrates that racial disparities in insulin treatment methods and diabetes outcomes remain even after adjustment for socioeconomic status. (Read the full article)

Microbial exposure during early life may prevent, or reduce, the risk of allergy development.

Allergic diseases are less common in children whose parents use hand dishwashing instead of machine dishwashing, and we hypothesize that this allergy-preventive effect is mediated via an increased microbial exposure. (Read the full article)

Celiac disease (CD) may develop at any age. Young children with CD are at particular risk for malabsorption and failure to thrive. HLA-DR3-DQ2 homozygotes are at the highest genetic risk and develop CD very early in life.

Most children with CD detected in screening by 4 years of age have no symptoms and normal growth. Symptoms are unrelated to HLA genotype. Autoantibody levels correlate higher with severity of mucosal lesions in symptomatic as compared to asymptomatic children. (Read the full article)

Although there is evidence regarding comorbidity of physical and mental disorders from clinical samples of specific disorders and treatment registries, there is limited evidence from systematic samples of youth with comprehensive information on the full range of mental and physical disorders.

This report is the first study to investigate the specificity of associations between a broad range of mental and physical conditions by using a large, systematically obtained pediatric sample with enriched information from electronic medical records and direct interviews. (Read the full article)

Handheld echocardiography is a more portable and lower-cost alternative to standard echocardiography for rheumatic heart disease screening. Direct comparison of handheld echocardiography and auscultation for the detection of rheumatic heart disease has not been done previously.

Handheld echocardiography significantly improves detection of rheumatic heart disease compared with auscultation alone and may be a cost-effective screening strategy in developing countries. (Read the full article)

Early psychosocial exposures are increasingly recognized as crucial to health throughout life. A possible mechanism is physiologic dysregulation due to stress. Cortisol in hair is a new biomarker assessing long-term hypothalamic-pituitary-adrenal axis activity.

Added early psychosocial exposures seem to increase infant long-term hypothalamic-pituitary-adrenal axis activity and risk of common childhood diseases in a cumulative manner, supporting the model of physiologic dysregulation as a plausible mechanism through which early detrimental exposures determine health outcomes.

Insulin resistance plays a role in obesity. Recently it has been associated with increased risk of AD. Aβ42 and PSEN1 are molecules associated with increased risk of later AD. Patients affected by AD show elevated levels of plasma Aβ42.

Levels of Aβ42 and PSEN1 are significantly elevated in obese adolescents and correlated with the degree of both adiposity and systemic insulin resistance. (Read the full article)

Distribution of infant formula discharge packs to breastfeeding mothers is common practice in maternity care facilities in the United States. Receiving discharge packs is associated with shortened exclusive breastfeeding duration. Many efforts have been made to discourage this practice.

From 2007 to 2013, there has been a marked reduction in distribution of discharge packs containing infant formula to breastfeeding mothers in hospitals and birth centers in the United States. (Read the full article)

Conventional invasive pneumococcal disease (IPD) definition using laboratory confirmation lacks sensitivity. Using a vaccine-probe design, the FinIP trial showed that IPD disease burden and vaccine-preventable disease incidence were fourfold higher when a more sensitive outcome, clinically suspected IPD, was used.

Vaccine-preventable disease incidence (ie, absolute reduction due to PCV10 vaccination) during routine vaccination program was threefold with the more sensitive outcome of clinically suspected IPD compared with the conventional IPD definition. This has major implications for cost-effectiveness of PCVs. (Read the full article)

Associations have been reported between celiac disease (CD) and numerous autoimmune conditions in adults and children. However, current screening guidelines do not consider patients with rheumatic diseases to be at high risk for CD.

The prevalence of CD in children presenting for rheumatology evaluation was found to be 2% by routine serologic screening. The majority of screening-detected CD cases had no CD-associated symptoms. Gluten restriction was found to relieve some musculoskeletal complaints. (Read the full article)

Discharge from the NICU requires coordination and may be delayed for nonmedical reasons. Predicting when patients will be medically ready for discharge can avoid these delays and result in cost savings for the hospital.

We developed a supervised machine learning approach using real-time patient data from the daily neonatology progress note to predict when patients will be medically ready for discharge. (Read the full article)

Prenatal diagnosis may lead to benefits in outcomes for certain forms of critical congenital heart disease. Despite recognized benefits, single-center studies and focused regional efforts suggest that prenatal detection rates for congenital heart disease remain low in the United States.

We describe prenatal detection rates for a large cohort of neonates and infants undergoing heart surgery across a range of congenital heart defects. Additionally, this study adds new information by demonstrating geographic variability of prenatal detection rates across the United States. (Read the full article)

Interactive activities and routines promote early childhood language skills and subsequent educational achievement. Population studies describing parent-child participation in interactive activities and their associations with early child development among vulnerable populations are needed.

Significant disparities exist in parenting practices that promote child development between economically advantaged and disadvantaged parents. Participating in less interactive activities was associated with increased risk of developmental delay among low-income families, suggesting a need to enrich parenting practices.

The value of ultrasound imaging for the diagnosis, prognosis, and surgical planning of cryptorchidism is limited at best.

Ultrasound remains grossly overused by referring physicians throughout Ontario, Canada, which resulted in a 3-month delay to definitive surgery and unnecessary expenditures. (Read the full article)

Making a diagnosis of Kawasaki disease (KD) is often a diagnostic dilemma. This dilemma is confounded when children present with symptoms consistent with known, common respiratory viruses and/or with KD symptoms that could potentially be attributed to a respiratory virus.

Patients with KD commonly have a concurrent respiratory viral infection. Clinicians should not dismiss the diagnosis of KD based on the presence of respiratory symptoms. Furthermore, a positive respiratory virus test result should not be used to exclude the diagnosis of KD. (Read the full article)

Infants born very prematurely or with a very low birth weight are known to have an increased risk of attention-deficit/hyperactivity disorder (ADHD). Results concerning late preterm children are controversial and studies examining fetal growth represented by weight for gestational age are scarce.

We demonstrate that each declining week of gestation increases the risk of ADHD. Also, late preterm infants have an increased risk. Furthermore, as weight for gestational age becomes smaller than 1 SD below the mean, the risk of ADHD increases. (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)

Many studies have suggested that autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD) are commonly co-occuring neurodevelopmental conditions.

In children with co-occurring ASD and ADHD, an initial ADHD diagnosis may be associated with delayed ASD diagnosis and a higher likelihood of ASD diagnosis older than 6 years of age. Clinicians should consider ASD when evaluating young children presenting with ADHD symptoms. (Read the full article)
