Autism is widely considered a heterogeneous disorder in terms of etiology and phenotype. Although autism is usually a lifelong disorder, little is known about the rate or timing of how children develop regarding their communication and social functioning.

Utilizing annual evaluations for a large population of children with autism, we describe the 6 most common trajectories from diagnosis through age 14 years. Trajectories revealed considerable variation, and high socioeconomic status children were more likely to experience rapid improvement. (Read the full article)

Although developmental care in NICUs reduces the stress experienced by preterm infants, the actual level of developmental care may vary and little is known about how the level of developmental care relates to preterm infants’ neurobehavioral performance.

The study demonstrates the relationship between variations in developmental care in NICUs and the neurobehavior of preterm infants. Infants from NICUs with high-quality developmental care compared with infants from units with low quality of care evidenced a better neurobehavioral profile. (Read the full article)

Studies have found that the degree of detail with which palliative care is described and the order in which options are presented can affect end-of-life decisions. None of these studies, though, involved decisions regarding very premature infants.

Unlike other end-of-life decisions, those regarding extremely premature infants are influenced neither by the degree of detail nor order of presentation of management options. Deep-seated values embodied in the reasons given for these choices suggest why they are so robust. (Read the full article)

Preterm, growth-restricted infants are at high risk of necrotizing enterocolitis (NEC). NEC occurs most frequently in infants who have received enteral feeds. It is common practice to delay introduction of enteral feeds in these infants.

Early introduction of enteral feeds results in earlier achievement of full enteral feeding. Early feeding is not associated with a higher risk of NEC. Delayed feeding is associated with a higher risk of cholestasis. (Read the full article)

Although all residents progressively assume responsibility for clinical skills under the teaching and supervision of attending physicians, senior residents also assume responsibility for teaching and supervising. This leads to a dynamic negotiation of responsibilities, particularly on clinical work rounds.

A better understanding of how attending physicians and senior residents negotiate shared responsibilities for teaching and supervising, and the context in which this negotiation occurs, may clarify assumptions and set expectations for resident training. (Read the full article)

Diabetes during pregnancy has been associated with general development impairments in offspring; however, associations between autism and maternal diabetes have been inconsistent. Few studies have examined related conditions accompanied by underlying increased insulin resistance and their association with developmental outcomes.

This population-based study in young children provides evidence that maternal metabolic conditions are a risk factor for autism, developmental delay without autistic symptoms, and impairments in several domains of development, particularly expressive language, after adjusting for sociodemographic and other characteristics.

Estimates of youth participation in strangulation activity, commonly referred to as the "choking game," range from 5% to 11%. Previous studies have documented correlations between youth choking game participation and health risks such as substance use and mental health issues.

Among Oregon eighth-graders surveyed, >6% had ever participated in the choking game. Participation was linked to poor nutrition and gambling among females, exposure to violence among males, and sexual activity and substance use among both genders. (Read the full article)

Cross-sectional imaging can reduce the negative appendectomy rate (NAR) in children being evaluated for suspected appendicitis; however, the ability of diagnostic imaging to decrease NAR may vary by age and gender.

Cross-sectional imaging leads to a significant reduction in NAR for children younger than 5 years and girls older than 10 years. For boys older than 5 years being evaluated for uncomplicated appendicitis, advanced imaging appears to have limited value. (Read the full article)

Valid parental permission requires that the decision be both informed and voluntary. Previous research has focused on the informational components of decision-making (eg, disclosure and understanding), with little empirical attention to the voluntariness of decisions.

We address this gap by examining the voluntariness of parents making research or treatment decisions in pediatric oncology. We identify demographic and contextual correlates of voluntariness and highlight the clinical implications of the findings for physicians and investigators. (Read the full article)

Evaluating dehydration severity is a challenging task. Clinical dehydration scores that combine multiple clinical findings are promising. One clinical dehydration scale score has been developed and subsequently evaluated; however, few participants in the derivation and validation studies were significantly dehydrated.

In children requiring intravenous rehydration, the dehydration scale displayed moderate reliability and weak associations with objective measures. Thus, although the scale can assist in assessing dehydration, it should not be used in isolation to dictate interventions (eg, intravenous rehydration, hospitalization). (Read the full article)

Disparities are known to exist in the prescription of opioid analgesics among racial and ethnic groups in the management of postoperative, cancer, and emergency department pain in patients across all ages, including children.

Race is associated with an unequal burden of perioperative pain and opioid adverse effects in children. Relatively, African American children had higher postoperative pain, and Caucasian children had higher incidences of opioid related adverse effects. (Read the full article)

Although several randomized trials have examined the efficacy of serotonin receptor inhibitors in the treatment of repetitive behaviors, there still remains clinical uncertainty as to whether these agents are effective in treating such behaviors in children and adults with autism spectrum disorders.

The goal of this meta-analysis was to examine randomized trials of serotonin receptor inhibitors for treating repetitive behaviors in autism spectrum disorders. Although a small but significant effect of these agents was observed, this effect is likely due to the selective publication of trial results. (Read the full article)

Following a rapid increase from 1980 to 2001, the prevalence of obesity among school-age children and adolescents in the United States has plateaued. Few studies have examined obesity trends among younger children in the past decade, and findings are inconsistent.

Among children aged <6 years at this multisite pediatric practice, the prevalence of obesity was fairly stable during 1999–2003, but substantially decreased during 2004–2008. This decrease was smaller among children insured by Medicaid than children insured by non-Medicaid health plans. (Read the full article)

Assessing for adequacy of supervision in the clinical setting is challenging and may result in significant variability in care. Clinicians must quickly decide if a child and family necessitate direct counseling, further intervention, or require reporting to state agencies.

This study identified the most important characteristics for the evaluation of the adequacy of supervision of a young child. A standardized scale using these characteristics may result in an efficient means to reduce variability in care. (Read the full article)

Rates of coverage for recommended vaccinations in adolescents are substantially lower than Healthy People 2010 goals. Reminder/recall is an evidence-based strategy that is proven to increase immunization rates in both adults and young children.

This study shows that reminder/recall is effective in increasing adolescent immunization rates. Practices may also benefit financially from conducting reminder/recall in this age group if they are able to generate additional well visits and keep supply costs low. (Read the full article)

Conflicting results exist concerning long-term outcome in healthy infants with metabolic acidosis at birth.

Neonates who appear well after perinatal metabolic acidosis do not have an increased risk of neurologic or behavioral problems in need of referral actions or pedagogic arrangements at the age of 6.5 years. (Read the full article)

More than one-tenth pediatric patients use complementary and alternative medicines (CAM) for their medial conditions in the United States. Traditional Chinese medicine (TCM) is the most commonly used CAM in East Asia but large-scale epidemiologic studies are lacking.

In comparing TCM and non-TCM users among children in Taiwan, children’s age and parental TCM use were strongly associated with TCM use. Additionally, dyspepsia and allergic rhinitis were positively related to increasing TCM use. (Read the full article)

Omega-3 fatty acids (O3FA) are commonly used as complementary treatments in pediatric psychiatric disorders, including Tourette’s disorder (TD), and are well known to have anti-inflammatory properties. However, no studies to date have examined the effects of O3FA on pediatric TD.

This is the first double-blind, placebo-controlled clinical trial of O3FA in pediatric TD. The results indicate that O3FA supplementation may be beneficial in the reduction of tic-related impairment for some children and adolescents with TD, but not tics per se. (Read the full article)

Batteries, especially button batteries, are an important source of pediatric injury. Recent reports suggest that fatal and severe button battery ingestions are increasing.

An estimated 3289 battery-related ED visits occurred annually among US children <18 years of age, averaging 1 visit approximately every 3 hours. The number and rate of visits increased significantly during the 20-year study period, driven by increases during the last 8 study years. (Read the full article)

Despite recommendations and a universal immunization program, a recent survey reported suboptimal influenza vaccination coverage in children aged 6 to 23 months in Ontario. Little is known about predictors of coverage in young children to target immunization strategies.

Full influenza vaccination coverage in young children in Ontario is <10% and declining since the 2006–2007 season. Medically high-risk children including low birth weight infants are more likely to be immunized, but maternal and health services characteristics remain important. (Read the full article)

Previous research has identified low rates of employment and postsecondary education for youth with autism, but generalizability has been limited by small samples.

Using national data, the authors of this study found that youth with autism are at high risk for no postsecondary education or employment, especially in the first 2 years after high school. Findings highlight the need for improved transition planning. (Read the full article)

Isolated methylmalonic acidemia, one of the most common inborn errors of organic acid metabolism, is known to be associated with variably impaired intellectual functioning and severe biochemical and clinical abnormalities. However, the neurocognitive outcomes have yet to be fully described.

This research defines the neurocognitive phenotype of isolated methylmalonic acidemia and identifies processing speed as a specific impairment. Clinical, biochemical, and molecular genetic covariates were explored. A history of hyperammonemia at diagnosis was found to correlate with poorer cognitive outcomes. (Read the full article)

The hypothesis that maternal prenatal folic acid lowers risk for childhood malignancy in offspring is supported by experimental and epidemiologic evidence, including 2 Canadian ecologic studies that showed inverse associations for some cancer types in the very young.

Examining Surveillance Epidemiology and End Results Program data, a decrease in the incidence of some childhood cancers (Wilms tumor, primitive neuroectodermal tumors) was observed in those <5 years after mandatory US folic acid fortification, with stronger effects detected in infants.

Although soy protein–based infant formula is known to support physical growth equal to that of infants fed cow's milk–based formula, data are lacking on developmental status of infants fed soy formula compared with breast milk or milk formula.

Infants fed soy protein–based formula scored within normal limits on standardized developmental testing and did not differ from infants fed cow’s milk–based formula. Breastfed infants have a slight advantage on cognitive development compared with formula-fed infants. (Read the full article)

Numerous studies report disparate use of dental services among poor children. National estimates vary based on the data source, and little is known about how age, race, and health plan affect use of dental services among Medicaid-enrolled children.

Based on of Medicaid claims, dental services improved since 2002 but varied substantially by state, age, and type of insurance. Children entering school had the highest prevalence of care as did children in primary care case management and health maintenance organizations. (Read the full article)

Although many children are treated in general emergency departments, many such facilities have limited pediatric capabilities. Transfer to academic centers improves outcomes for critically ill patients, but transfers of noncritically ill children have not been well studied.

Although more than half of these patients are seriously ill, many transferred patients are discharged directly from the emergency department or are admitted for less than 24 hours. Orthopedic problems, gastrointestinal conditions, and traumatic head injury are the most common complaints. (Read the full article)

In 2011, the Accreditation Council on Graduate Medical Education increased restrictions on resident duty-hours. Further changes have been considered, including greater work-hour restrictions and lengthening residency. Residents’ views about these policies are unclear.

This is the first systematic, national inquiry into resident opinions on reduced work-hours and longer residency. More pediatric residents support than oppose reduced hours, and a minority would add a year to residency to achieve them. (Read the full article)

Adherence to guidelines has generally been shown to improve patient care and reduce the cost of care. Current understanding of the varying reasons why clinicians deviate from guidelines is based on surveys and retrospective reviews.

We examined clinician deviations from guidelines in a prospective fashion and attempted to categorize those deviations. Better elucidation of clinician reasoning behind deviations may inform care improvement and help define strategies to eliminate unjustifiable deviations. (Read the full article)

Fetal factors that predispose infants to necrotizing enterocolitis (NEC) have been extensively studied. Maternal factors that may affect future risk for NEC are less clear.

We hypothesized that maternal factors were the primary cause of NEC. Through a case-control design we determined that maternal smoking predisposes infants to the development of NEC. Our results highlight the importance of smoking cessation in pregnancy. (Read the full article)

Neonatal hearing screening occasionally fails because of several perinatal and neonatal factors. However, the effect of mode of delivery on hearing screening has not yet been established.

We show significantly more failures on hearing screening in cesarean delivery infants. Hence, the timing of screening after cesarean delivery should preferably be postponed beyond 48 hours to improve success rate, minimize maternal anxiety, and decrease costs. (Read the full article)

There are limited cross-sectional data from observational studies of adolescents showing that regular participation in physical activity is associated with a higher quality of life status, whereas time spent in screen-based entertainment is associated with a poorer quality of life.

Adolescents who were physically active (particularly engaging in outdoor activity) over a 5-year period had higher quality of life than their less active peers. Conversely, high levels of screen-based entertainment over 5 years negatively affected quality of life status. (Read the full article)

Providers who speak Spanish, regardless of their proficiency level, may use Spanish for clinical care without seeking professional interpretation. Failure to use professional interpretation increases the risk for miscommunication and can lead to patient harm.

Providing residents with objective feedback on Spanish language proficiency decreased willingness to use Spanish in straightforward clinical scenarios. Language proficiency testing, coupled with institutional policies requiring professional interpretation, may improve care for patients with limited English proficiency. (Read the full article)

Early speech and language delays are risk factors for later developmental and social difficulties. It is easier to identify them retrospectively than prospectively. Population characteristics and prevalence rates make screening problematic.

Using data from a birth cohort, this study identifies predictors of language performance at 5 years and 4 patterns of change between 3 and 5 years, comparing those who change with those whose profile remains low across time points. (Read the full article)

Literature about polymorphic expression of an apparent life-threatening event (ALTE), particularly that concerning discrimination between ALTE with evident cause and idiopathic ALTE, is scarce. Relationships between SIDS and ALTEs have been supposed but data are still controversial and no genetic data are available.

Genetic analysis (5HTT and MAOA) on ALTEs and idiopathic ALTEs discriminated the 2 syndromes and found a link between the idiopathic form and SIDS. Consequently, we hypothesized that the 2 latter syndromes could be different phenotype expressions of a common genetic base. (Read the full article)

Prevalence estimates for neurologic and neurodevelopmental disorders in children vary widely, and there is uncertainty as to what extent the individual disorders overlap. Most previous prevalence studies have been based on survey data and not on specialist-confirmed diagnoses.

This study used nationwide register data to determine the proportions of Norwegian children diagnosed with autism spectrum disorder, attention-deficit/hyperactivity disorder, epilepsy, and cerebral palsy and to study how the disorders overlap. All diagnoses were specialist-confirmed. (Read the full article)

Febrile infants in the first 90 days may have life-threatening serious bacterial infection. Well-appearing febrile infants with serious bacterial infections cannot be distinguished from those without by examination alone. Variation in care resulting in both undertreatment and overtreatment is common.

The systemwide implementation of an evidence-based care process model for the care of febrile infants in Intermountain Healthcare was associated with increased delivery of evidence-based care, improved infant outcomes, and lower costs. This model adopted nationally can improve value. (Read the full article)

Adherence to Pediatric Advanced Life Support resuscitation guidelines for children with sepsis is low; however, few studies have been conducted in the tertiary care emergency department setting.

Adherence to septic shock guidelines in a tertiary care pediatric emergency department is low. Adherence to fluid guidelines and the entire PALS algorithm was associated with a shorter hospital length of stay. (Read the full article)

Various studies have documented marked racial/ethnic disparities in children’s receipt of dental services at single time points or brief periods.

This study reveals significant improvements in children’s receipt of dental care overall, as well as a dramatic narrowing of African American/white disparities in children’s receipt of dental services over the last 40 years in the United States. (Read the full article)

Late preterm infants are at risk for a variety of developmental impairments; however, little is known about developmental differences among children born within the term range of 37 to 41 weeks’ gestation.

This study links comprehensive birth record data from 128 050 term births to children’s school records 8 years later. Analyses establish that, even among the "normal term" range, gestational age is an important independent predictor of academic achievement. (Read the full article)

Sudden cardiac death in young athletes is an uncommon but devastating event. Addition of routine electrocardiogram (ECG) screening to standard preparticipation care may reduce the number of sudden deaths. Lack of data regarding effectiveness and costs has prevented widespread implementation.

Adding ECG screening to current preparticipation evaluation is not cost-effective. Cost is driven primarily by the evaluation of the large number of false-positive findings. An ECG-only screening strategy is more cost-effective. (Read the full article)

Physical punishment is associated with aggression, delinquency, and internalizing conditions in childhood, as well as a range of Axis I mental disorders in adulthood. More research is needed on the possible long-term relationship between physical punishment and mental health.

To our knowledge, this is the first nationally representative examination of physical punishment and a range of Axis I and II disorders, gender interactions, and proportion of mental disorders in the general population that may be attributable to physical punishment. (Read the full article)

Moderately preterm-born children (32–35^6/7 weeks’ gestation) are at risk for both neonatal morbidities after birth and developmental delays in early childhood. It is unknown whether neonatal morbidities contribute to the developmental delays of this particular group.

Of all neonatal morbidities commonly seen in moderately preterm-born children, only hypoglycemia increased the risk of developmental delay after moderately preterm birth. A concerted effort to prevent hypoglycemia after birth might enhance developmental outcome in this group. (Read the full article)

Clinical trials have demonstrated that prophylactic human papillomavirus (HPV) vaccines are highly effective in preventing HPV infection, but the impact of vaccination on HPV prevalence rates in real-world, community settings is uncertain.

This study provides evidence of a substantial decrease in the prevalence of vaccine-type HPV among young women and evidence of herd protection in a community only 4 years after the quadrivalent HPV vaccine was licensed. (Read the full article)

Data suggest that delivery at high-volume, high-technology hospitals reduces neonatal mortality. No study has examined other complications or compared the effects in multiple states by using a study design to control for unmeasured differences in case mix.

The survival benefit to delivering at a high-level NICU between 1995 and 2005 is larger than previously reported and varies between states. The survival benefits affect both extremely and moderately preterm infants. Complication rates were similar between hospital types. (Read the full article)

Dental composites composed of bisphenol A (BPA) derivatives are common alternatives to amalgam, but may release BPA. Gestational BPA exposure has been associated with poorer behavior in children. A safety trial of amalgam found worse psychosocial outcomes for children randomized to composites.

In the trial, greater exposure to bisphenol-A-glycidyl-methacrylate-based dental composite in children aged 6 to 10 years was associated with worse self-reported psychosocial functioning at 5-year follow-up. There were no such associations with exposure to dental amalgam or urethane-dimethacrylate-based polyacid-modified composite (compomer). (Read the full article)

Eating disorder not otherwise specified (EDNOS) is the most common eating disorder diagnosis. Binge eating disorder, 1 type of EDNOS, is associated with obesity among adults. Little is known about the health outcomes associated with other types of EDNOS.

This is the first study to evaluate the prospective association of full and subthreshold bulimia nervosa, binge eating disorder, purging disorder, and other EDNOSs with specific mental and physical health outcomes. (Read the full article)

Many drugs are not approved for use in pediatric patients and there is limited evidence on their safety and efficacy in children. Furthermore, there is concern that the quality of pediatric trials is inferior compared with adult trials.

For conditions with a high disease burden in children, only a small proportion of clinical drug trials study pediatric patients. Most pediatric trials are not funded by industry, and the deficiency of evidence is largest in developing countries. (Read the full article)

The American Academy of Pediatrics prioritized detection of mental illness in children presenting to emergency departments (ED) by using standardized clinical tools. Only a minority of ED physicians indicate that they use evidence-based screening methods to assess mental health concerns.

This study presents the psychometrics of the HEADS ED (home, education, activities/peers, drugs/alcohol, suicidality, emotions/behavior, discharge resources), a brief, standardized screening tool for pediatric EDs. This tool ensures key information is obtained for decision-making, determining acuity level, and areas of need. (Read the full article)

To date, 4 small to moderate sized studies have revealed conflicting results on the clinically important question whether thrombocytopenia contributes to persistent patent ductus arteriosus (PDA) in very immature, preterm infants.

Thrombocytopenia in the first 24 hours after birth was not associated with the incidence of PDA at postnatal day of life 4 to 5 in a large cohort of preterm infants with <1500 g birth weight. Platelet dysfunction, rather than platelet number, might play a role in ductus arteriosus patency. (Read the full article)

Since the introduction of effective vaccines in the United States, the incidence of invasive Haemophilus influenzae type b (Hib) disease in children aged <5 years has decreased by 99%. In 2007, in response to limited vaccine supply, Hib booster doses were deferred for 18 months.

This review found no significant change in the incidence of invasive Hib disease in the United States during the booster dose deferral period, suggesting that booster dose deferral is a reasonable approach to Hib vaccine shortages in the short-term. (Read the full article)
