Adherence to infant feeding recommendations in the United States is low. The prevalence of early introduction of solid foods (<4 months of age) in the United States has been estimated to range from 19% to 29%.

Mothers’ most commonly cited reasons for early solid food introduction include perception of readiness, hunger, wanting to feed something in addition to breast milk or formula, perception of interest in solids, advice from a clinician, and to improve infant’s sleep. (Read the full article)

Varicella vaccine is known to be highly effective, with added benefit from a second dose.

This study demonstrates the lasting effectiveness of varicella vaccine and the benefit of the second dose. Breakthrough varicella occurred soon after vaccination, varicella rates did not increase over 14 years, and there was no increase in zoster in the cohort. (Read the full article)

A gap exists with lack of programs to help mothers breastfeed. The 2012 American Academy of Pediatrics' "Policy Statement on Breastfeeding and the Use of Human Milk" re-emphasized breastfeeding as an important public health initiative rather than a lifestyle choice.

Families who receive care in a primary care setting that has implemented a "breastfeeding-friendly" office protocol may have increased rates of exclusive breastfeeding. This study evaluated an accepted clinical protocol in a large, diverse pediatric primary care setting. (Read the full article)

Previous studies have suggested that health care providers, family members, friends, and others play a role in shaping parents’ vaccination decisions. Other research has suggested that the media can influence whether parents decide to vaccinate their children.

Through the application of social network analysis, this study formally examines and quantifies how parents are influenced by the people and sources around them. Its findings suggest that social networks are important, particularly for parents who do not completely vaccinate. (Read the full article)

Pulse oximetry testing in newborns can detect asymptomatic cases of critical congenital heart defects and has been added to the US Recommended Uniform Screening Panel. However, the impact that earlier diagnosis may have on survival in this population is unclear.

One-year survival for infants with critical congenital heart defects has been improving over time, yet mortality remains high. Survival has been greatest for those diagnosed after 1 day of age and may increase more with screening using pulse oximetry. (Read the full article)

Survival of children with spinal muscular atrophy type 1 is determined by treatment choice: tracheostomy with mechanical ventilation, noninvasive mechanical ventilation, or a palliative approach. Few data are available on life expectancies with different approaches.

The present study provides data comparing therapeutic strategies that affect life expectancy. Clinicians involved in the care of patients with spinal muscular atrophy type 1 should be aware of survival trends while awaiting more definitive therapeutic strategies. (Read the full article)

Perforation in the setting of retained esophageal foreign body is rare, but can be catastrophic. The role of imaging in screening for injury after removal has not previously been studied.

The rate of esophageal injury among children with retained esophageal foreign body is 1.3%. Intraoperative findings suggestive of injury are predictive of perforation. Routine chest radiography is not warranted in those who do not meet this criterion. (Read the full article)

The Ages and Stages Questionnaires (ASQ) has been validated in many countries and translated into numerous languages. In most publications, it has been reported that the ASQ is accurate in detecting true problems in apparently healthy children and even in children with biological risk factors.

This report compares the third version of the ASQ and the Bayley Scales of Infant and Toddler Development, Third Edition, assessments. Psychometric properties showed a tendency to improve with testing age and when comparing term versus extremely preterm children. (Read the full article)

Despite proven health benefits, human papillomavirus (HPV) vaccination rates are among the lowest of all routine immunizations. No previous large-scale trial has compared the benefit of automated decision support directed at clinicians, families, or both in any context.

We found that a clinician-focused intervention was most effective for initiating the HPV vaccine series, whereas a family-focused intervention supported completion. Decision support directed at both clinicians and families most effectively promotes HPV vaccine series receipt. (Read the full article)

A low-level risk of intussusception after rotavirus vaccines, ~1 to 2 cases per 100 000 vaccinees, exists in some settings. In the United States, a risk of 1 in 65 000 was excluded, but lower risk could exist.

A persistent clustering of intussusception events 3 to 6 days after dose 1 indicates the possibility of a low-level risk of intussusception of ~0.8 cases per 100 000 vaccinees. The documented benefits of rotavirus vaccine far outweigh this low-level risk of intussusception. (Read the full article)

Hospitalizations under observation status are presumed to be shorter and less resource-intensive, but utilization for pediatric observation-status stays has not been studied.

Children’s hospitals use observation status with great variation. Resource utilization for pediatric patients under observation status overlaps substantially with inpatient-status utilization, calling into question the utility of segmenting pediatric patients according to billing status. (Read the full article)

The American Academy of Pediatrics recommends that all preterm infants receive human milk; however, little is known about the use of human milk in US advanced care neonatal units.

Routine use of human milk and use of donor milk in neonatal advanced care units increased from 2007 to 2011, particularly among units providing intensive care. There is geographic variation in the use of human milk in these units. (Read the full article)

Blood lead levels well below 10 µg/dL are now recognized as causing adverse cognitive effects, including lower scores on standardized reading and math tests.

This is the first study to show that reading readiness early in kindergarten is independently associated with blood lead levels well below 10 µg/dL. Results suggest that lead exposure may have a larger impact on urban education than national estimates suggest. (Read the full article)

Self-medication with antibiotics available without prescription is among the main causes of antibiotic misuse in the developing world and is associated with antibiotic resistance. Inappropriate antibiotic prescription is common in children. Patient expectations seem to influence physicians’ advice.

This study demonstrates that even in places where antibiotics are unregulated, improving physician prescribing habits could reduce irrational use overall and also future caregiver-driven misuse. Physician training in adequate antibiotic prescription could be a cost-effective intervention in these settings. (Read the full article)

The United States switched from whole-cell to acellular pertussis vaccines during the 1990s. Whether pertussis risk during a California outbreak differed between teenagers who previously received whole-cell or acellular pertussis vaccines early in life has not been reported.

We evaluated pertussis risk in 10 to 17 year olds at Kaiser Permanente Northern California during a recent pertussis outbreak. Those given whole-cell pertussis vaccines in childhood were more protected than those given acellular pertussis vaccines. (Read the full article)

Excessive weight gain over the first 18 months of life may have consequences for later body size. However, the relationship of weight gain in this period to atherogenic risk factors in later childhood is not well characterized.

Early postnatal weight gain from birth to 18 months is independently associated with childhood overweight and obesity, excess central adiposity, and greater arterial wall thickness at age 8 years. (Read the full article)

Introduction of the pneumococcal conjugate vaccine was associated with decreased invasive pneumococcal disease (IPD) in children. Few data exist on the impact in infants aged 1 to 90 days, who are too young to be fully immunized.

The incidence and proportion of IPD in Utah infants aged 1–90 days remained stable after vaccine introduction. IPD caused by PCV7 serotypes decreased significantly in the post-vaccine period. Serotype 7F emerged as the predominant serotype and commonly resulted in meningitis. (Read the full article)

Atherosclerotic cardiovascular diseases are rooted in childhood. Vascular intima-media thickness (IMT) and elasticity are early surrogate markers of atherosclerosis. In adults, cardiorespiratory fitness is associated with enhanced arterial elasticity and decreased IMT.

Fitness was favorably associated with aortic IMT and elasticity in adolescents. The association was independent of several cardiometabolic risk factors. In fit adolescents, the increase in IMT during the preceding 6 years was smaller compared with low-fit peers. (Read the full article)

Although concussion is increasingly being diagnosed in the pediatric population, little is known about what factors lead to prolonged postconcussive symptoms in children. In particular, the effect of previous history of concussion on recovery from a repeat injury is unclear.

Children with a history of previous concussion, particularly recent or multiple concussions, are at increased risk for prolonged symptoms after concussion. This suggests that repeat concussion, particularly within a vulnerable time window, may lead to longer duration of symptoms. (Read the full article)

Elevated blood pressure (BP) has long-term influence on the atherosclerotic process. The relative predictive ability of the standard BP definition endorsed by the National High Blood Pressure Education Program and the recently proposed 2 simplified definitions has not been studied.

Simplified pediatric BP tables predict risk of high adult arterial stiffness as well as the complex table does. These simple screening tools could be used for identifying pediatric subjects at risk and for intervening to improve adult cardiovascular outcomes. (Read the full article)

Uric acid (UA) is associated with hypertension in children, after body weight adjustment. Whether the whole spectrum of variables, such as visceral adiposity, insulin resistance, puberty, and renal function, influence the relationship between UA and blood pressure is unknown.

In a cohort of children at relatively high cardiovascular risk, the association between UA and blood pressure levels is independent of several well-known factors implicated in the development of hypertension, such as insulin resistance, pubertal status, and renal function. (Read the full article)

Monovalent rotavirus vaccine was introduced for infants in the United States in 2008. Previous US evaluations have not specifically assessed the performance of this vaccine under routine use.

Using the same methodology and covering the same time period, high effectiveness (~90%) was demonstrated for the monovalent and the pentavalent rotavirus vaccine series against rotavirus disease resulting in emergency department/inpatient care, in children up to 2 years of age. (Read the full article)

Screening for hypertension in asymptomatic children and adolescents occurs during routine care. For those with elevated blood pressure, a repeat measurement within 1 to 2 weeks is recommended. However, little is known about patterns of care after an incident elevated blood pressure.

In a population of 72 625 children and adolescents, 6108 (8.4%) had an incident elevated blood pressure. Among these, 1275 (20.9%) had their blood pressure measurement repeated within 1 month. However, few individuals with an incident elevated blood pressure subsequently developed hypertension. (Read the full article)

Pneumococcal conjugate vaccines are effective in preventing pneumococcal disease but are also costly. Although the current US immunization schedule recommends 4 doses, many countries have adopted 3-dose schedules that have worked well, but may provide less protection against pneumococcal disease.

Changing the US 13-valent pneumococcal conjugate vaccine schedule from 3 to 2 primary doses while keeping a booster dose would save $412 million annually but might lead to moderate increases in pneumococcal disease, especially otitis media and pneumonia. (Read the full article)

Obstacles to vaccine delivery, including poverty, reduced access to medical care, and incomplete understanding of vaccine safety and importance, result in suboptimal coverage rates in some populations, allowing for disease outbreaks. Multicomponent interventions are successful in increasing immunization coverage rates.

We show that collaboration with local resources, including the county health department and a large community-based organization, effectively increases immunization coverage rates in low-income, resource-poor children. (Read the full article)

There is wide variation in testing and treatment of children hospitalized with pneumonia. Limited data are available on diagnostic testing patterns and the association of test utilization with disposition outcomes for children with pneumonia evaluated in the emergency department (ED).

Significant variation exists in testing for pediatric pneumonia. EDs that use more testing have higher hospitalization rates. However, ED revisit rates were not significantly different between high- and low-utilizing EDs, suggesting an opportunity to reduce testing without negatively affecting outcomes. (Read the full article)

Diabetic ketoacidosis (DKA) is a short-term complication of type 1 diabetes and is a major cause of preventable hospitalization in children. Hospital resource utilization and readmission rates for DKA across the US are not known.

Readmission for DKA within a year of hospitalization is common, accounting for one-fifth of all DKA admissions. Resource use, hospital length of stay, and readmission rates vary widely across major US children’s hospitals, even after adjusting for hospital differences in patients. (Read the full article)

The evaluation of blunt head trauma in children who undergo cranial computed tomography will occasionally reveal incidental findings. These findings may require further evaluation or intervention. The prevalence of incidental findings has previously been described using small cohorts, limiting generalizability.

This study is the largest pediatric multicenter description of the prevalence of incidental findings on cranial computed tomography. Incidental findings are categorized by urgency to describe the spectrum of abnormalities, providing a context for clinicians faced with these unexpected results. (Read the full article)

Variation in the emergency department (ED) use of radiographs for asthma, bronchiolitis, and croup exists. Unnecessary radiographs contribute to higher costs of care, decreased ED efficiency, and increased radiation in children.

Despite no changes in guidelines to support routine use, there is a significant upward trend in the use of radiographs for children with emergency department visits for asthma. Pediatric-focused EDs use significantly fewer radiographs for asthma, bronchiolitis, and croup. (Read the full article)

Blood cultures are a common investigation in children admitted to the hospital with skin and soft tissue infections. The yield of blood cultures in this condition is unknown.

Blood cultures are not useful in children admitted to the hospital with uncomplicated skin and soft tissue infections, and they may be associated with increased length of hospital stay. (Read the full article)

Preterm and low birth weight infants are at increased risk of hospitalization due to rotavirus gastroenteritis, and rotavirus vaccine is immunogenic and well tolerated among these infants when provided at or after discharge from the NICU.

Many preterm infants with a birth weight of ≤1500 g are not eligible to receive rotavirus vaccination because they remain in the NICU beyond the upper age limit recommended for immunization. New strategies are needed. (Read the full article)

Evaluating for elevations in alanine aminotransferase (ALT) is a common screening test for the presence of nonalcoholic fatty liver disease (NAFLD). NAFLD is less common among non-Hispanic blacks. Better predictors of NAFLD are needed to identify individuals in most need of screening.

Relative to other ethnicities, metabolic syndrome and insulin resistance performed poorly at identifying non-Hispanic black adolescents with ALT elevations. The presence of metabolic syndrome may therefore not be an adequate trigger for NAFLD screening. Triglyceride elevations performed similarly between groups in identifying ALT elevations.

The Faces Pain Scale–Revised and Color Analog Scale are self-report pain scales that are commonly used for children in the clinical and research settings.

The Faces Pain Scale–Revised and Color Analog Scale overall demonstrate strong psychometric properties in children 4 to 17 years of age, including within subgroups of age, sex, and ethnicity. Convergent validity, however, is questionable in children <7 years old. (Read the full article)

Pediatric early warning scores (PEWS) for hospital inpatients have been developed to identify patients at risk for deterioration. Beyond triage, similar systems that identify ill patients and predict requirements for a higher level of care are needed in the emergency department.

The validity of the different PEWS in pediatric emergency care patients has never been evaluated. This study showed that PEWS are capable of detecting children in need of ICU admission. (Read the full article)

Unintentional injuries lead to a significant number of children suffering from long-lasting posttraumatic stress symptoms. Therefore, early identification of individuals at risk is crucial to provide preventative interventions. However, currently, no early screener has been evaluated in preschool-aged children.

Good sensitivity (85%) and acceptable specificity (63%) were found for an early screening measure for preschool-aged children after accidental injury. Hence, the 21-item Pediatric Emotional Distress Scale–Early Screener, a reliable and valid early screening instrument, is suggested for use within a stepped-care model. (Read the full article)

Invasive methicillin-resistant Staphylococcus aureus (MRSA) in children is associated with high morbidity and mortality. Although reductions in health care–associated MRSA infection among adults are documented, it is unclear if a similar trend is occurring among children.

Data from population-based surveillance were analyzed to assess changes in invasive MRSA infection incidence over time. This analysis describes the epidemiology and trends of invasive MRSA infections among children in 9 US metropolitan areas and estimates national burden. (Read the full article)

Previous studies have shown that nonmedical exemptions (NMEs) to immunization cluster geographically and contribute to outbreaks of vaccine-preventable diseases such as pertussis. The 2010 pertussis resurgence in California has been widely attributed to waning immunity from acellular pertussis vaccines.

This study provides evidence of spatial and temporal clustering of NMEs and clustering of pertussis cases and suggests that geographic areas with high NME rates were also associated with high rates of pertussis in California in 2010. (Read the full article)

The 1-dose childhood varicella vaccination program in the United States resulted in dramatic declines in varicella incidence, hospitalizations, and deaths. There is little information on the impact of the 2006 recommendation for 2-dose varicella vaccination of children on varicella epidemiology.

In the first 5 years of the 2-dose varicella vaccination program, declines in varicella incidence were seen in all age groups, including infants who are not eligible for varicella vaccination, providing evidence of the benefit of high population immunity. (Read the full article)

Several studies have been published evaluating the impact of 2011 Accreditation Council for Graduate Medical Education duty hour regulations. Although resident quality of life may be improved, it appears that resident education and patient care may be worse.

This is the first study to evaluate pediatric program director approval of 2011 Accreditation Council for Graduate Medical Education Common Program Requirements and the perceived impact of the regulations on patient care, resident education, and quality of life. (Read the full article)

Obesity and overweight can seriously affect health outcomes. Many obesity prevention interventions have been proposed, but few have been effective. Motivational interviewing in primary care seems promising, but results in BMI control are controversial and require further investigation.

This is the first study to demonstrate the effectiveness of pediatrician-led motivational interviewing for BMI control in overweight children aged 4 to 7 years. Nevertheless, no effect was observed in boys or when the mother’s education level was low. (Read the full article)

School outbreak investigation in Quebec, Canada suggested that adolescents previously vaccinated with 2 doses of measles vaccine beginning at 12 months of age were at greater measles risk than those whose first dose was given at ≥15 months of age.

Greater measles risk among earlier first-of-2-dose vaccine recipients was replicated as a generalized provincial finding during the 2011 epidemic in Quebec, Canada. The mechanism remains unknown, but the findings warrant additional evaluation in the context of measles elimination efforts. (Read the full article)

An increasing number of parents have concerns about childhood vaccines. Parents consistently cite their child’s provider as influential in their vaccine decision-making. Little is known about how providers communicate with parents about vaccines and which communication strategies are important.

How providers initiate the vaccine recommendation at health supervision visits appears to be an important determinant of parent resistance. Also, when providers pursue their original vaccine recommendations in the face of parental resistance, many parents subsequently agree to vaccination. (Read the full article)

To prevent asthma exacerbations, asthma guidelines recommend ongoing monitoring of patients’ asthma symptoms to promote timely adjustments of therapy to achieve and maintain optimal control. Existing tools, validated for ongoing monitoring, have significant limitations in children.

Our study established longitudinal validation of the Asthma Symptom Tracker, a novel tool designed for use by children or their parents to facilitate ongoing monitoring of patients’ asthma symptoms and proactive medical decision-making to prevent acute exacerbations. (Read the full article)

Global health is of increasing interest and relevance to North American pediatric trainees. Opportunities for resident global health training and exposure are most often limited to electives or trainees in dedicated global health tracks.

A series of short, structured, participatory global child health modules improved knowledge and were well received and integrated within academic programs. Such modules enable global health learning for all residents, including those who never intend to practice overseas. (Read the full article)

Vaso-occlusive episodes (VOEs) are a common complication of sickle cell disease, resulting in morbidity. Magnesium is a vasodilator and has been shown to improve red blood cell hydration. Previous small studies have suggested that treatment with magnesium may decrease VOEs.

Intravenous magnesium sulfate is well tolerated in relatively high doses but had no effect on the length of stay in hospital, pain scores, or cumulative analgesia used in children admitted with painful VOEs in sickle cell disease. (Read the full article)

Pediatric surgery is performed in a variety of hospital types. General surgeons as well as fellowship-trained pediatric surgeons and surgical subspecialists perform inpatient operative procedures on infants and children. The distribution of procedures between specialists is not well characterized.

This study describes the demographics of pediatric surgery: the hospital type, the surgical procedures, and the quantity of inpatient pediatric surgery in the U.S. today. By implication, the data has much to inform health care about hospital and practitioner workforce. (Read the full article)

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

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

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)

Although appendicitis is the most common surgical cause of abdominal pain in pediatrics, its diagnosis remains elusive. When evaluated independently, clinical scoring systems and ultrasonography have been shown to have low to moderate sensitivity in the diagnosis of appendicitis.

Our study evaluated the accuracy of a clinical practice guideline combining the Samuel’s pediatric appendicitis score and selective ultrasonography as the primary imaging modality for children with suspected appendicitis. Our clinical pathway demonstrated high sensitivity and specificity. (Read the full article)

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

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