REVIEW
Ryan J Herringa
PURPOSE OF REVIEW: PTSD in youth is common and debilitating. In contrast to adult PTSD, relatively little is known about the neurobiology of pediatric PTSD, nor how neurodevelopment may be altered. This review summarizes recent neuroimaging studies in pediatric PTSD and discusses implications for future study. RECENT FINDINGS: Pediatric PTSD is characterized by abnormal structure and function in neural circuitry supporting threat processing and emotion regulation...

OBJECTIVE: The bare spot (BaS) is a central, well-circumscribed focal defect in the glenoid articular surface, with reported adult incidence of 1-2%. We aimed to reassess MRI features of BaS in the pediatric population and determine its etiology. MATERIALS AND METHODS: A retrospective search of our database from June 2014 to October 2015 was performed for shoulder MRI in patients between 5 and 25 years and then subdivided into four groups: group 1, 5-10 years; group 2, 10-15 years; group 3, 15-18 years; group 4, 20-25 years...

OBJECTIVE: Psychotropic medications are frequently prescribed to children with autism spectrum disorder (ASD), but little is known about the prescribing practices of developmental-behavioral pediatricians (DBPs). Our objective was to determine whether clinical site, age, insurance, or comorbidities influenced DBPs prescribing psychotropic medication for children with ASD. METHODS: A retrospective analysis was performed using electronic health record data of all patients with ASD seen at 3 academic developmental-behavioral pediatrics (DBP) clinical programs from January 2010 to December 2011...

OBJECTIVE: Studies of early child development in sickle cell disease (SCD) have found modest associations between disease-related risks and developmental status in infants and toddlers, but such associations are evident by early elementary school. We screened 4-year-old children with SCD using 2 screening strategies to assess if biomedical risk factors for neurologic disease are related to developmental screening outcomes at this intermediate age. METHODS: Seventy-seven 4-year-old children with SCD (M = 4...

BACKGROUND AND OBJECTIVES: Given the nature of FMR1 gene expansions, most biological mothers, and often multiple other family members of children with fragile X syndrome (FXS), will have a premutation, which may increase individual and family vulnerabilities. This article summarizes important gaps in knowledge and notes potential implications for pediatric providers with regard to developmental and medical risks for children and adolescents with an FMR1 premutation, including possible implications into adulthood...

Effective rehabilitation of children with cerebral palsy (CP) requires intensive task-specific exercise but many in this population lack the motor capabilities to complete the desired training tasks. Providing robotic assistance is a potential solution yet the effects of this assistance are unclear. We combined a novel exoskeleton and exercise video game (exergame) to create a new rehabilitation paradigm for children with CP. We incorporated high density electroencephalography (EEG) to assess cortical activity...

This paper presents a modular, computationally-distributed "multi-robot" cyberphysical system designed to assist children with developmental delays in learning to walk. The system consists of two modules, each assisting a different aspect of gait: a tethered cable pelvic module with up to 6 degrees of freedom (DOF), which can modulate the motion of the pelvis in three dimensions, and a two DOF wearable hip module assisting lower limb motion, specifically hip flexion. Both modules are designed to be lightweight and minimally restrictive to the user, and the modules can operate independently or in cooperation with each other, allowing flexible system configuration to provide highly customized and adaptable assistance...

BACKGROUND: Adolescents can be vulnerable to diminished dignity in the hospital because young people have significantly different healthcare needs than children and adults. They like to cooperate with caregivers only when they get respectful and dignified care. Care without considering dignity can adversely influence the adolescents' recovery. However, many studies have been conducted on exploring the concept of the patients' dignity from the adult patients and fewer studies still have explored the dignity of young people...

INTRODUCTION: Several studies have shown that early identification of childhood hearing loss leads to better language outcomes. However, delays in the confirmation of hearing loss persist even in the presence of well-established universal newborn hearing screening programs (UNHS). The objective of this population-based study was to document the proportion of children who experienced delayed confirmation of congenital and early onset hearing loss in a UNHS program in one region of Canada...

Hydrocephalus (HC) is a common, debilitating neurological condition that requires urgent clinical decision-making. At present, neurosurgeons rely heavily on a patient's history, physical examination findings, neuroimaging, and clinical judgment to make the diagnosis of HC or treatment failure (e.g., shunt malfunction). Unfortunately, these tools, even in combination, do not eliminate subjectivity in clinical decisions. In order to improve the management of infants and children with HC, there is an urgent need for new biomarkers to complement currently available tools and enable clinicians to confidently establish the diagnosis of HC, assess therapeutic efficacy/treatment failure, and evaluate current and future developmental challenges, so that every child has access to the resources they need to optimize their outcome and quality of life...

REVIEW

The assessment of a child is quite different from that of adults and requires knowledge of normal variations in anatomy and physiology with growth and development. An important part of initial assessment includes triage and recognizing children with emergency signs so that they can be managed at the earliest to prevent death and referred timely to the specialist. After ruling out emergency signs, the children with priority signs require prompt assessment, management and referral to the specialist. In addition to normal history as in adults, prenatal and birth history, developmental history, immunization history, feeding history and social history are important for complete assessment of the child...

The craniovertebral junction (CVJ) has attracted more attention in pediatric medicine in recent years due to the progress in surgical technologies allowing a direct approach to the CVJ in children. The CVJ is the site of numerous pathologies, most originating in bone anomalies resulting from abnormal CVJ development. Before discussing the surgical approaches to CVJ, three points should be borne in mind: first, that developmental anatomy demonstrates age-dependent mechanisms and the pathophysiology of pediatric CVJ anomalies; second, that CT-based dynamic simulations have improved our knowledge of functional anatomy, enabling us to locate CVJ lesions with greater certainty; and third, understanding the complex structure of the pediatric CVJ also clarifies the surgical anatomy...

BACKGROUND: In humans, the heterochronic cascade composed of the RNA-binding protein LIN28 and its major target, the let-7 family of microRNAs (miRNAs), is highly regulated during human erythroid ontogeny. Additionally, down-regulation of the let-7 miRNAs in cultured adult CD34(+) cells or the over-expression of LIN28 in cultured erythrocytes from pediatric patients with HbSS genotype causes increased levels of fetal hemoglobin (HbF) in the range of 19-40% of the total. Therefore, we hypothesized that focused targeting of individual let-7 miRNA family members would exhibit regulatory effect on HbF expression in human adult erythroblasts...

Natural killer (NK) cells are critical in immune defense against infected, stressed or transformed cells. Their function is regulated by the heterogeneous expression of a wide array of surface receptors that shape its phenotypic diversity. Although NK cells develop in the bone marrow and secondary lymphoid tissues, substantive differentiation is apparent in the peripheral blood including known age-related variation. In order to gain greater insight into phenotypic and functional variation within peripheral blood NK cells across age groups, we used multi-parametric, polyfunctional flow cytometry to interrogate the NK cell variability in 20 healthy adults and 15 5-10, 11-15 and 16-20 year-old children...

REVIEW
Kendall S Frazier
The developing kidney is sensitive to both morphological and functional disturbances during the gestational and postnatal phases of growth and differentiation. Exposure to drugs or chemicals during these critical windows of renal development can result in aplasia, dysplasia, polycystic kidney disease, hydronephrosis, or other features characteristic of nephrotoxicity, including tubule dilation, necrosis, or mineralization. Functional effects can occur without associated morphological abnormalities. Differences in the timing of nephrogenesis and morphologic renal development among species help to explain specific phenotypes of various gestational and postnatal teratogens and nephrotoxins...

Parental opioid use is affecting the physical, developmental, and mental health of the pediatric population nationwide and raises questions of safety when these children remain in the care of opioid-addicted parents. Pediatric providers face many barriers to identifying and caring for children beyond the neonatal period who have been affected by parental opioid abuse both in utero and in the home. These barriers include communication between providers and services, identification of intrauterine exposure, parental opioid abuse screening, and knowledge of child protective services involvement...
