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)

Late-onset hypocalcemia is common in neonates, often presents with seizures or tetany, and is often attributed to transient hypoparathyroidism.

Late-onset hypocalcemia in neonates is often a sign of coexisting vitamin D deficiency and hypomagnesemia and is readily managed with therapy of limited duration, and neonates presenting with tetany or seizures due to hypocalcemia are unlikely to benefit from neuroimaging studies.

The rapidly rising prevalence of overweight and obesity among children and adolescents over the past 4 decades is a significant public health concern. Experts urge pediatric health care providers to provide routine obesity screening and counseling.

We provide the first nationally representative estimates of the rate of screening and counseling for adolescent obesity by pediatric health professionals. We also examine how socioeconomic factors and access to health care affect whether adolescents receive these services. (Read the full article)

Preterm infants from 33 gestational weeks can detect specific shape features (prism and cylinder) by touch (without visual control), and remember them; however, nothing is known about such abilities earlier in development.

The preterm infant, even when very immature (from 28 gestational weeks), is endowed with tactile sensory abilities: the exploration and memorization of an object by touch, the discrimination of a novel object, and the recognition of a familiar object after interference. (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)

Increased computed tomography (CT) use among adults and children presenting to emergency departments has spawned concern about associated radiation exposure. The risks and benefits of CT use for certain conditions, such as abdominal pain, among general pediatric populations remains unclear.

This study analyzes emergency department radiology trends between 1998 and 2008 among children with abdominal pain, highlighting a dramatic increase in CT use. Factors associated with CT ordering include older age, non-black race, and hospital admission. (Read the full article)

Tobacco smoke exposure is associated with increased morbidity in children, and exposure in cars can be particularly intense. The American Academy of Pediatrics policy statement recommends that pediatricians assist families in adopting smoke-free car policies.

In this study, few smoking parents had a strictly enforced smoke-free car policy. Low rates of pediatric health care providers addressing smoking in the car highlights the need for improved pediatric interventions to protect children from tobacco smoke toxins. (Read the full article)

When research involving children is determined to present greater than minimal risk but no potential for direct benefit, permission is required from both parents, unless one is not reasonably available. These requirements are variably understood and applied, and guidance is lacking.

In a study on newborn screening, a sizeable percentage of fathers were not reasonably available, reflecting complexities of parental status and family relations. Guidelines developed in this project may provide tools for researchers and institutions to apply in other contexts. (Read the full article)

Although it is known that relatively minor abusive injuries sometimes precede more severe physical abuse, the prevalence of these previous injuries in infants evaluated for abuse was not known.

A history of bruising or oral injury in a precruising infant evaluated for abuse should heighten the level of suspicion because these injuries are common in abused infants and rare in infants found not to be abused. (Read the full article)

Violence involving firearms is a leading cause of death among US youth ages 14 to 24. The emergency department is the primary medical setting for care of assault-injured youth and an underused but important setting for violence-prevention programs.

Among assault-injured youth seeking emergency department care, firearm possession rates are high, most obtained outside of legal channels. Higher rates of negative retaliatory attitudes and substance use among those youth with firearms increases risk of future lethal violence. (Read the full article)

Age-appropriate child safety seat use in the United States is suboptimal, particularly among children older than 1 year. Minority children have higher rates of inappropriate child safety seat use based on observational studies. Explanations for observed differences include socioeconomic factors.

White parents reported greater use of age-appropriate child safety seats for 1- to 7-year-old children than nonwhite parents. Race remained a significant predictor of age-appropriate restraint use after adjusting for parental education, family income, and information sources. (Read the full article)

Sibship size has been negatively associated with children’s language, cognitive, and academic outcomes. This phenomenon is often explained in terms of resource dilution, wherein more children in the home is associated with fewer parental resources allocated to each child.

The current study identifies a moderator of this relationship. Specifically, if children’s next-in-age older siblings exhibit high levels of cognitive sensitivity then sibship size is not significantly related to children’s vocabulary. (Read the full article)

Pulse oximeter is better than skin color assessment in the initial minutes of life. After sensor application, a delay occurs in the display of reliable saturation and heart rate. An appropriate method of sensor placement can minimize the delay.

Attaching sensor first to oximeter and then to neonate picked up signal faster than attaching it to the neonate first and then to the equipment. However, the time from birth to display of reliable signal was similar between the methods. (Read the full article)

Approximately 20% of US child passenger deaths involve an alcohol-impaired driver, typically in the child’s own vehicle. The higher the blood alcohol concentration of a driver, the more likely his or her child passenger was unrestrained in the fatal crash.

The risk of a child passenger dying while being transported with an alcohol-impaired driver varies meaningfully across states. These state-specific rates may help to inform renewed prevention efforts. (Read the full article)

Hookah use is increasing dramatically among US adolescents. Many consider it a safer alternative to cigarettes. Existing studies often use nonrepresentative local populations to assess prevalence and correlates of hookah use.

This study used a nationally representative sample of US high school seniors. It confirmed some previously found correlates and determined that adolescents of higher socioeconomic status were at high risk for hookah use. (Read the full article)

Passive or opt-out consent has been successfully used to recruit subjects in several investigational studies. However, institutional review boards are often inconsistent in their application of federal regulations regarding passive consent.

This study documented the variability among 24 local institutional review boards in their application of federal regulations regarding passive consent and parental acceptance of a passive consent strategy in a multicenter pediatric study. (Read the full article)

A previous study suggested that spine and pelvis views may be omitted from the follow-up skeletal survey protocol for suspected child abuse, when these views are normal on the initial skeletal survey, without limiting the sensitivity of the study.

This multicenter study provides estimates of the risk of missing occult fractures in the evaluation of suspected child abuse with omission of spine and pelvis views from the follow-up skeletal survey protocol. Results may be used to update practice recommendations. (Read the full article)

Movie ratings designed to warn parents about violence and sexual content have permitted increasing amounts of each in popular films. One potential explanation for this "ratings creep" is parental desensitization to this content as it becomes more prevalent in movies.

This study adds experimental evidence that parents become desensitized to movie violence and sex and are more willing to allow children to view such content. (Read the full article)

Delivering competent oral case presentations is an important clinical communication skill, yet effective means of improving trainees’ presentations have not been identified.

Oral presentation feedback sessions facilitated by faculty by using an 18-item competency-based evaluation form early in pediatric clerkships improved medical students’ subsequent oral presentations. Medical schools should consider implementing this evidence-supported practice. (Read the full article)

Off-label prescription of inhaled nitric oxide (iNO) to neonates <34 weeks’ gestation has increased during the past decade. In early 2011, the National Institutes of Health determined that the available evidence did not support iNO use in this population.

Use of iNO among neonates <34 weeks’ gestation has increased since 2011, entirely from greater use in extremely preterm neonates. Off-label prescription of this drug now accounts for nearly half of all iNO use in American NICUs. (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)

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)

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)

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)

Deferral of consent avoids delaying emergency interventions while ensuring consent to ongoing participation and use of data. Deferred consent is particularly important for enabling trials in pediatric settings, where many medicines and devices are unlicensed and untested for use.

Approaches for seeking deferred consent should balance the potential burden of obtaining consent against risk of bias due to outcome-related attrition. Ethics committees could consider approving data use when best efforts to obtain deferred consent are met with no response. (Read the full article)

Several injuries have been suggested to be disproportionately associated with abuse in young children, but rates of abuse among children with these injuries are not currently known.

Abuse is diagnosed commonly in children with sentinel injuries, including the majority of children <24 months with rib fractures. (Read the full article)

Recent studies highlight the abundance of commensal coagulase-negative staphylococci (CoNS) on healthy skin. Evidence suggests that CoNS actively shape the skin immunological and microbial milieu to resist colonization or infection by opportunistic pathogens, including methicillin resistant Staphylococcus aureus (MRSA), in a variety of mechanisms collectively termed colonization resistance. One potential colonization resistance mechanism is the application of quorum sensing, also called the Accessory Gene Regulator (agr) system, which is ubiquitous among staphylococci. Common and rare CoNS make autoinducing peptides (AIPs) that function as MRSA agr inhibitors, protecting the host from invasive infection. In a screen of CoNS spent media we found that Staphylococcus simulans, a rare human skin colonizer and frequent livestock colonizer, released potent inhibitors of all classes of MRSA agr signaling. We identified three S. simulans agr classes, and have shown intraspecies cross-talk between non-cognate S. simulans agr types for the first time. The S. simulans AIP-I structure was confirmed, and the novel AIP-II and AIP-III structures were solved via mass spectrometry. Synthetic S. simulans AIPs inhibited MRSA agr signaling with nanomolar potency. S. simulans in competition with MRSA reduced dermonecrotic and epicutaneous skin injury in murine models. Addition of synthetic AIP-I also effectively reduced MRSA dermonecrosis and epicutaneous skin injury in murine models. These results demonstrate potent anti-MRSA quorum sensing inhibition by a rare human skin commensal, and suggest that cross-talk between CoNS and MRSA may be important in maintaining healthy skin homeostasis and preventing MRSA skin damage during colonization or acute infection.
