Diabetic ketoacidosis (DKA) is a common and serious first manifestation of diabetes mellitus in children. During initial evaluation, the venous blood pH is frequently used to make the diagnosis and classify the severity of DKA.

This study demonstrates that the serum bicarbonate concentration is a simple and accurate predictor of DKA and its severity and can be used in lieu of venous pH measurement, especially in resource-poor settings where access to pH measurement is limited. (Read the full article)

Weak recommendations exist to guide emergent neuroimaging decisions in children with first, unprovoked seizures. The prevalence of and risk factors associated with clinically relevant abnormalities on neuroimaging have not been well defined in prospective studies.

Clinically relevant intracranial abnormalities on neuroimaging occur in 11% of children with first, unprovoked seizures. Emergent/urgent abnormalities, however, occur in <1%, suggesting that most of these children do not require emergent neuroimaging. Specific clinical findings identify patients at higher risk.

Prior studies have found a positive relationship between macro-level indicators of home foreclosure and child maltreatment rates. The extent to which home foreclosure may be associated with child protective services involvement at the micro level is largely unknown.

Foreclosure filings are positively associated with child protective services involvement. However, this is true of the periods before and after a filing, which are characterized by economic and other stress, which may drive this association more than the filing itself. (Read the full article)

Stevens-Johnson syndrome (SJS) is a rare and severe immunologic phenomenon characterized by rash and mucous membrane disease. SJS may be triggered by medications and, less commonly, by infections such as Mycoplasma pneumoniae (Mp). Outbreaks of SJS are exceedingly rare.

We describe the largest SJS outbreak reported in children, which was also Mp-associated. In the first case-control study of this disease, we identify predictors of Mp-associated SJS versus non–Mp-associated SJS, including fewer skin lesions, pneumonia, and elevated erythrocyte sedimentation rate.

Electronic cigarette (e-cigarette) use in adolescence is increasing. E-cigarette use has been associated with cigarette use, but there has been little study of other psychosocial risk factors for e-cigarette use and their relationship with cigarette use.

Approval and use of e-cigarettes and cigarettes among friends and family were strongly associated with cigarette and e-cigarette use in a cohort of adolescents in southern California. (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 routine childhood immunization schedule is crowded during the first 2 years, leading to deferred doses and limiting the addition of new vaccines. Combination vaccines can reduce the "shot burden" and improve coverage rates and timeliness.

Antibody response rates to antigens contained in an investigational hexavalent vaccine (DTaP5-IPV-Hib-HepB) were noninferior to licensed comparator vaccines when given as a 3-dose infant series. The safety profile was similar to control except for increased rates of mild-to-moderate, self-limited fever. (Read the full article)

Small-for-gestational-age neonates are at risk for thrombocytopenia during the first days and weeks after birth. However, the incidence, duration, severity, responsible mechanism, value of platelet transfusions, and risk of death from this variety of neonatal thrombocytopenia are unknown.

Ten percent of thrombocytopenic small-for-gestational-age neonates have a recognized cause for low platelets (aneuploidy, extracorporeal membrane oxygenation, disseminated intravascular coagulation); they have a high mortality rate (65%). Ninety percent have a moderate, transient (2 weeks), hyporegenerative thrombocytopenia with a low mortality rate (2%). (Read the full article)

Street youth demonstrate elevated mortality compared with the general adolescent and young adult population. Suicide is a leading cause of death among street youth. Many street youth have experienced childhood maltreatment, including abuse and neglect.

In this prospective cohort of street youth, self-reported attempted suicide and history of childhood maltreatment were common. Individuals who experienced childhood physical abuse, emotional abuse, or emotional neglect were at highest risk of attempting suicide. (Read the full article)

Attention is a prerequisite for neurocognitive and behavioral functioning, having a crucial role in academic and social child development. Children with traumatic brain injury have pronounced deficits in attention, but the nature and consequences of these deficits remain unclear.

Lapses of attention represent a core attention deficit after pediatric mild traumatic brain injury with risk factors for complicated traumatic brain injury, or moderate/severe traumatic brain injury. Importantly, lapses of attention explain the relation between intelligence and parent-rated attention problems. (Read the full article)

Previous studies have shown that concomitant administration of the quadrivalent human papillomavirus vaccine with MCV4 and Tdap was generally well tolerated and did not interfere with the immune responses to the respective vaccines.

Concomitant administration of the novel 9-valent human papillomavirus vaccine with MCV4 and Tdap, 2 vaccines that are currently recommended for routine vaccination of adolescents, did not compromise the safety, tolerability, and immunogenicity of the individual vaccines. (Read the full article)

Selective eating is a common, burdensome eating pattern in young children. A significant subset remain selective eaters at least until adolescence and, for some, adulthood. The question is whether selective eating is a serious enough developmental pattern to warrant intervention.

This study examines whether selective eating, at 2 levels of severity, is associated with current and future psychological problems. Because moderate levels of selective eating were associated with impairment, selective eating falls within the diagnosis of avoidant/restrictive food intake disorder. (Read the full article)

The American Academy of Pediatrics recommends parent-child reading from infancy through at least kindergarten, the span of maximal brain growth. Home literacy environment, including reading behaviors and access to books, has been shown to promote oral language and print concepts.

Home reading environment is positively associated with activation of brain areas supporting narrative comprehension and mental imagery in preschool children. This offers novel insight into the neurobiological foundations of emergent literacy and potential effect of shared reading during early childhood. (Read the full article)

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)

In response to growing demand from trainees, many pediatric residency programs offer global health (GH) experiences for their residents. There is diversity in what is offered at programs across the country.

This is the most comprehensive assessment of US pediatric residency training opportunities in GH. These opportunities are prevalent and increasingly formalized as tracks. However there remain gaps in universal pretravel preparation and coordination across GH partnerships nationally. (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.

Rudeness is routinely experienced by hospital-based medical teams. Individuals exposed to mildly rude behavior perform poorly on cognitive tasks, exhibit reduced creativity and flexibility, and are less helpful and prosocial.

Rudeness had adverse consequences on diagnostic and procedural performance of members of the NICU medical teams. Information-sharing mediated the adverse effect of rudeness on diagnostic performance, and help-seeking mediated the effect of rudeness on procedural performance. (Read the full article)

Late preterm infants, compared with full-term infants, have less proficiency in reading and math at school age, with increased need for individualized educational plans and special education services. They also have lower cognitive performance on standardized IQ exams.

Late preterm infants have worse outcomes at school entry, and development is variable during the preschool years, so socioeconomic status, language spoken in the home, maternal education, maternal race, and being a late preterm infant have a large impact. (Read the full article)

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)

Unmet health care need in adolescence is associated with poor contemporaneous health outcomes. Adolescence is increasingly recognized as an important stage of the life-course, when there may be a significant opportunity for health care interventions to improve later health outcomes.

The odds of adverse adult health outcomes were 13% to 52% higher among subjects who had reported unmet health care need in adolescence, compared with subjects with similar adolescent health outcomes, insurance coverage, and sociodemographic background but no unmet need. (Read the full article)

High bilirubin levels are associated with sensorineural hearing loss. Exchange transfusions are recommended when bilirubin levels reach certain thresholds. However, the relative and excess risks of hearing loss in infants with bilirubin levels at/above exchange transfusion thresholds are unknown.

In this Northern California population of term and late preterm infants, elevated bilirubin levels were not associated with an increased risk of sensorineural hearing loss unless the levels were at least 10 mg/dL above exchange transfusion thresholds. (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)

Research has shown that parent feeding practices are associated with adolescent weight status and dietary intake. It is unknown whether certain factors such as parent and child weight status concordance or discordance influence parents’ use of specific feeding practices.

Findings from the current study suggest that parents use the highest levels of pressure-to-eat feeding practices when parents and adolescents are both nonoverweight and the highest levels of food restriction when parents and adolescents are both overweight/obese. (Read the full article)

Historically, children with end-stage renal disease who initiated chronic dialysis during the first year of life were far less likely to survive or successfully receive a kidney transplant compared with those who initiated chronic dialysis at older ages.

In recent years, survival has improved markedly among children who initiate chronic peritoneal dialysis at <1 year of age. Among those infants who initiate dialysis after the neonatal period and later undergo kidney transplantation, graft survival has improved as well. (Read the full article)

Embryonal tumors occur almost exclusively in children. The group is heterogeneous and includes relatively common pediatric tumors as well as rare tumors. The incidence rate for hepatoblastoma has been increasing in some countries.

This population-based study is the first comprehensive study on embryonal tumors in German children. Incidence rates, trends, and survival for 1991 through 2012 are presented. A statistically significant increasing trend for hepatoblastoma was detected for the first time in Europe. (Read the full article)

Concern of the risk of malignancy from ionizing radiation has prompted many to advocate for judicious use of computed tomography (CT) and as low as necessary radiation doses administered per scan. Recent analysis has shown a decline in CT utilization.

We identified decreases in CT utilization between 2004 and 2012 for the 10 most common diagnostic groups receiving CT. Decreases were typically associated with increases in alternate imaging modalities. We provide a possible reason for the decrease in CT utilization. (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)

Increasing percentages of youth are living with chronic medical conditions. Although adolescents face peak risks for onset and intensification of alcohol and marijuana use, we know little about these behaviors and their associations with treatment adherence among chronically ill youth.

This study quantifies alcohol and marijuana use behaviors among a heterogeneous sample of chronically ill youth in aggregate and by condition, and measures associations between alcohol use/binge drinking and knowledge about alcohol interactions with medications/laboratory tests and also treatment nonadherence.

Subjective social status (SSS), a person’s sense of their or their family’s position in the socioeconomic hierarchy, is strongly related to adult health but is not a robust predictor of adolescent health. Developmental trajectories of SSS underlying this discrepancy are unknown.

Five SSS trajectories are present in adolescence/emerging adulthood. Four stably reflect objective socioeconomic status. The fifth represents a subset of socially disadvantaged youth with "rose-colored glasses" early on. Lower SSS and membership in the fifth trajectory increase health risk. (Read the full article)

Adding second-stage automated auditory brainstem response (ABR) testing for infants who failed the initial OAE test in a two-stage neonatal hearing screening has been shown to reduce false referrals to the hearing clinic.

Infants with hearing loss may be missed by a 2-stage hearing screening because they pass the automated ABR test. In our study, a significant number of infants with hearing loss >45 decibel hearing level passed screening with automated ABR. (Read the full article)

Electronic cigarette use among youth is rising exponentially. Among other concerns, modified electronic cigarettes can be used to vaporize cannabis. However, no scientific data have been published on the rates of using electronic cigarettes to vaporize cannabis among youth.

This study presents rates of vaporizing cannabis among a sample of high school students (N = 3847). Rates of vaporizing cannabis were high among lifetime e-cigarette users (18.0%), lifetime cannabis users (18.4%), and lifetime dual cannabis and e-cigarette users (26.5%). (Read the full article)

Preschool language delay predicts poorer academic performance, employment opportunities, and social relationships. Language for Learning, a systematic, population-based intervention for 4-year-olds with low language, is feasible, acceptable and has short-term benefits, but long-term benefits are unknown.

Population ascertainment at age 4 followed by a yearlong, one-on-one home program benefited phonological skills (an important literacy determinant) at age 6, but not the primary language outcomes. To be cost-effective, future follow-up would need to demonstrate lasting academic benefits. (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)

Unsupervised medication exposures increased during the previous decade, despite child-resistant packaging and caregiver education. To achieve the Healthy People 2020 objective of reducing emergency department visits for unintentional pediatric medication overdoses, targeted interventions including improved safety packaging may be needed.

Since 2010, emergency department visits for unsupervised medication exposures started to decrease. Most visits involved solid dose medications, typically for adult use. Most liquid medication exposure visits involved 4 over-the-counter pediatric products and may be more readily amenable for interventions. (Read the full article)

Intervention strategies are needed to reduce underage drinking. Meta-analyses of youth alcohol brief interventions (BIs) conclude that therapist-delivered BIs are efficacious; however, to maximize public health impact, recommendations include using technology to streamline intervention delivery, for which evidence is lacking.

A single-session BI, delivered by a computer or therapist in the emergency department, shows promise for underage drinkers. Findings for the stand-alone computer BI are particularly appealing given the ease of future implementation. (Read the full article)

Choosing career paths can be a difficult decision for residents contemplating fellowship training. Limited resources are available to residents to help guide their choices.

This article provides additional descriptions and insight into actual lifestyle and workplace environments for pediatric residents who choose fellowship training compared with those who do not. (Read the full article)

Two prospective studies of children with septic arthritis have shown that the addition of dexamethasone to antibiotic therapy contributes to clinical and laboratory improvement. Nevertheless, the mainstay of treatment remains antibiotics alone.

This study, which was conducted outside a randomized controlled trial, demonstrates that children with septic arthritis treated early with a short course of adjuvant dexamethasone show earlier improvement in clinical and laboratory parameters than children treated with antibiotics alone.

Use of a standard treatment protocol with stringent weaning guidelines for infants with neonatal abstinence syndrome supports improved outcomes including shorter duration of opioid exposure and length of hospital stay.

We demonstrate generalizability of a protocol-driven weaning strategy for improvement in hospital outcomes for neonatal abstinence syndrome. After adoption, adherent protocol-adopting centers improved outcomes and eliminated differences in outcomes compared with centers with preexisting stringent weaning protocols.

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)

Previous studies found that 2010–2011 trivalent inactivated influenza vaccine (TIV) and 13-valent pneumococcal conjugate vaccine (PCV13) were associated with statistically significant increased risks of febrile seizures (FS) in the United States.

Estimated FS relative risks after TIV or PCV13 adjusted for DTaP were >1, although not statistically significant and lower than previous estimates. Same-day administration of TIV and PCV13 did not result in more FS compared with separate-day vaccination. (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)

Infants with neonatal abstinence syndrome are hospitalized for longer after birth and are more likely to be from highly vulnerable families. Determining long-term outcomes is difficult because this is a large and chaotic population.

Tricycle riding is a common activity in children. In calendar year 2012, tricycle accidents were the most common cause of reported toy-related deaths in children. Little research has been conducted regarding tricycle-related injuries and how to counsel parents appropriately.

This study uses nationally representative data to investigate various characteristics of tricycle-related injuries in children to better counsel parents. This study highlights the importance of helmet and elbow pad use and parental supervision. (Read the full article)

Although nonphysician reentry transitions have been characterized in the literature, little is known about the reentry of residents after either short-term (1-month elective) or long-term (12-month training) global health experiences abroad.

Reverse culture shock may be a useful conceptual framework for understanding the range of emotions felt by pediatric residents when they reenter residency after global health experiences, particularly if these experiences were long term. (Read the full article)

Minimal parent supervision and early pubertal maturation independently forecast alcohol misuse among adolescent girls. It is not known if pubertal timing amplifies risks associated with inadequate supervision during the formative years when youth are first exposed to alcohol.

Early maturing girls who enter secondary school with high levels of behavioral autonomy report a dramatic increase in alcohol abuse. The etiology of their problems with alcohol can be traced, in part, to heightened risks arising from low parent supervision. (Read the full article)

Hypoplastic left heart syndrome (HLHS) is a critical congenital heart defect with high mortality. With advances in surgical intervention in recent years, survival of infants with HLHS has improved, but information on long-term survival using population-based data is limited.

In this population-based study, survival to adolescence of children with HLHS has significantly improved in recent years. Among infant survivors, >90% survived up to 18 years. Gestational age, birth weight, and neighborhood poverty may affect survival. (Read the full article)

The vitamin D concentration in breast milk of women taking 400 IU vitamin D per day is relatively low, leading to vitamin D deficiency in breastfeeding infants. As a result, the American Academy of Pediatrics recommends breastfeeding infant vitamin D supplementation within days after birth.

Maternal vitamin D supplementation alone with 6400 IU/day safely supplies breast milk with adequate vitamin D to satisfy the requirement of her nursing infant and offers an alternate strategy to direct infant supplementation. (Read the full article)

Urethral catheterization is a painful, yet common procedure to obtain a sterile urine sample in young children. There are conflicting results regarding the effectiveness of lidocaine to reduce pain, and it is unclear if it should be routinely used.

In young children, combined topical and intraurethral lidocaine does not reduce pain during urethral catheterization and is associated with more pain than nonanesthetic lubricant during instillation. Clinicians should use noninvasive methods of analgesia during this painful procedure. (Read the full article)

Premature infants are at risk for medical and neurodevelopmental sequelae. Close monitoring is an important role for primary care providers. Premature infants have high use of health care services; however, little is known about the role of health supervision visits.

This study explores the utilization and value of health supervision visits for premature infants. Fewer than half were found to be fully adherent to the health supervision visit schedule, resulting in preventive care gaps and immunization delays. (Read the full article)
