Strategies to improve the quality of hospital care are needed if ongoing gains in child health and survival are to be made. We previously reported on improvements in the quality of case management in hospitals following a guideline-based intervention in Lao PDR, with variation in the degree of change achieved between clinical conditions. This study aims to understand the factors that influenced the uptake of the guideline-based intervention, and its impact on care. This qualitative study was embedded in a mixed-methods evaluation of guideline implementation in nine hospitals in Lao PDR...

Neuroblastoma (NB) is the most common extracranial pediatric solid tumor. Around 70% of patients with metastatic disease at diagnosis present bone-marrow infiltration, which is considered a marker of poor outcome; however, the mechanism underlying this specific tropism has to be elucidated. Tumor-derived exosomes may support metastatic progression in several tumors by interacting with the microenvironment, and may serve as tumor biomarkers. The main objective of this study was to identify an exosomal signature associated with NB metastatic bone-marrow dissemination...

BACKGROUND: Historically, the options for mechanical circulatory support in infants, particularly those with single-ventricle physiology, have been limited and outcomes have generally been poor. We report a new approach implemented for long-term support in a series of such patients. METHODS: This study is a single-center case series of 7 patients with single-ventricle physiology after stage 1 palliation supported with mechanical circulatory support using a novel technique, between May 2014 and September 2015...

BACKGROUND: Unexplained wrist pain is a common presentation in children. To our knowledge, no studies have explored the clinical utility of magnetic resonance imaging (MRI) in the diagnostic workup of pediatric patients. METHODS: We retrospectively reviewed 307 consecutive wrist MRIs ordered at a tertiary-care pediatric hospital. Demographic data and the indication for imaging were recorded and grouped into admitting categories. The final impression of each MRI was scored with regard to potential impact on future treatment (0 = normal, 1 = minimal, 2 = moderate, 3 = high)...

OBJECTIVE: Juvenile idiopathic arthritis (JIA) is the most common childhood rheumatic disease and has a strong genomic component. To date, JIA genetic association studies have had limited sample sizes, used heterogeneous patient populations, or included only candidate regions. This study focuses on identifying new associations among oligoarticular and polyarticular rheumatoid factor negative (RF(-) ) JIA, which are clinically similar and the most prevalent JIA disease subtypes. METHODS: Three cohorts totaling 2,751 oligoarticular and polyarticular RF(-) JIA cases were genotyped on the Affymetrix Genome-Wide SNP Array 6...

OBJECTIVE: To assess the prevalence of congenital heart disease (CHD) in Germany in relation to phenotypes, severity and gender. DESIGN: Cross-sectional registry study. SETTING: We analyzed data from patients with CHD born between 1996 and 2015. PATIENTS: A total of 26 630 patients, registered with the NRCHD, were born between 1996 and 2015. 10 927 patients were excluded from the current analysis due to prior registration with the NRCHD under the German PAN Prevalence Study, which showed a potential bias in the inclusion of this patient population (proportion of mild cardiac lesions was comparatively high due to improved diagnostic capability for earlier identifying minor lesions)...

Recurrent somatic mutations of H3F3A in aggressive pediatric high-grade gliomas generate K27M or G34R/V mutant histone H3.3. H3.3-G34R/V mutants are common in tumors with mutations in p53 and ATRX, an H3.3-specific chromatin remodeler. To gain insight into the role of H3-G34R, we generated fission yeast that express only the mutant histone H3. H3-G34R specifically reduces H3K36 tri-methylation and H3K36 acetylation, and mutants show partial transcriptional overlap with set2 deletions. H3-G34R mutants exhibit genomic instability and increased replication stress, including slowed replication fork restart, although DNA replication checkpoints are functional...

Once incision and drainage of fascial space abscess is performed, irrigation of deep spaces with saline and antibiotic solution should be done daily for effective elimination or reduction of infection. Various advocated aids for irrigation into deeper areas are: small pediatric nasogastric feeding tubes, French catheter, polyethylene irrigation tubes and scalp vein infusion set. All these aids have major inherent disadvantages like, they tend to kink inside the deep spaces limiting the reach of irrigating solution into deeper spaces, are not readily available in dental departments and have to be discarded after every use...

Antipsychotic drug prescriptions for pediatric populations have increased over the past 20 years, particularly the use of atypical antipsychotic drugs such as risperidone. Most antipsychotic drugs target forebrain dopamine systems, and early-life antipsychotic drug exposure could conceivably reset forebrain neurotransmitter function in a permanent manner that persists into adulthood. This study determined whether chronic risperidone administration during development modified locomotor responses to the dopamine/norepinephrine agonist, D-amphetamine, in adult rats...

Pediatric chronic pain is a challenging entity to evaluate and treat as it encompasses a wide variety of presentations often with overlapping psychosocial implications. Chronic pain may have significant effects upon a child's involvement in academic, athletic, and social participation. If unrecognized, it may have deleterious effects upon family interactions and stability. The treatment of pediatric chronic pain is focused on not only providing analgesia, but also on assisting the child and family with reintegrating into a more functional lifestyle...

A third of all pediatric fractures involve the growth plate and can result in impaired bone growth. The growth plate (or physis) is cartilage tissue found at the end of all long bones in children that is responsible for longitudinal bone growth. Once damaged, cartilage tissue within the growth plate can undergo premature ossification and lead to unwanted bony repair tissue, which forms a "bony bar." In some cases, this bony bar can result in bone growth deformities, such as angular deformities, or it can completely halt longitudinal bone growth...

OBJECTIVE: In neurotrauma care, a better understanding of treatments following traumatic brain injury (TBI) has led to a significant decrease in morbidity and mortality in this population. TBI represents a significant medical problem, and complications following TBI are associated with the initial injury and post-event intracranial processes such as elevated intracranial pressure (ICP) and brain edema. Consequently, appropriate therapeutic interventions are required to reduce brain tissue damage and improve cerebral perfusion...

Although transcatheter arrhythmia ablation (TCA) has been performed in children for over two decades, guidelines for routine use of post-ablation transthoracic echocardiography (TTE) are absent. We sought to determine the efficacy of TTE after apparently uneventful TCA procedures in detecting adverse findings and identify predisposing factors. A retrospective review of clinical and procedural data on patients who underwent TCA for supraventricular arrhythmias from 2000 to 2015 was performed. Pre- and post-ablation TTE data were reviewed...
