Pediatric brain tumors are the most common solid tumors in children and are also a leading culprit of cancer-related fatalities in children. Pediatric brain tumors remain hard to treat. In this study, we demonstrated that medulloblastoma, pediatric glioblastoma, and atypical teratoid rhabdoid tumors express significant levels of acid ceramidase, where levels are highest in the radioresistant tumors, suggesting that acid ceramidase may confer radioresistance. More importantly, we also showed that acid ceramidase inhibitors are highly effective at targeting these pediatric brain tumors with low IC50 values (4...

Despite the high incidence of Down syndrome (DS) in Arab countires, the incidence and outcomes of myeloid leukemia of DS (ML-DS) have not been studied. We evaluated 206 pediatric acute myeloid leukemia (AML) patients diagnosed between 2005 and 2012 and identified 31 (15%) ML-DS. The incidence of ML-DS was 48 per 100,000 compared to 0.6 per 100,000 for AML in non-DS children. Thus, patients with DS had 80-fold increased risk of ML-DS compared to AML in non-DS children. The median age at diagnosis was 1.8 years, male/female ratio was 1...

BACKGROUND: Post-transplant malignancy (PTM) remains a concern among pediatric kidney transplant (PKT) recipients. STUDY DESIGN: Between 1963 and 2015, 884 pediatric (age: 0-17 years old) recipients received 1055 PKTs at our institution. Cox proportional hazards models were constructed to identify risk factors for PTM after PKT with time-to-first-PTM as a primary outcome. Secondly, the hazard of death or graft loss was calculated in patients who developed PTM. RESULTS: Median patient survival was 33 years (interquartile range [IQR]: 18...

Hereditary Multiple Exostoses (HME) is a rare pediatric disorder caused by loss-of-function mutations in the genes encoding the heparan sulfate (HS)-synthesizing enzymes EXT1 or EXT2. HME is characterized by formation of cartilaginous outgrowths-called osteochondromas- next to the growth plates of many axial and appendicular skeletal elements. Surprisingly, it is not known whether such tumors also form in endochondral elements of the craniofacial skeleton. Here, we carried out a retrospective analysis of cervical spine MRI and CT scans from 50 consecutive HME patients that included cranial skeletal images...

BACKGROUND: We aimed to describe newborn body composition and identify which anthropometric ratio (weight/length; BMI; or ponderal index, PI) best predicts fat mass (FM) and fat-free mass (FFM). METHODS: Air-displacement plethysmography (PEA POD) was used to estimate FM, FFM and body fat percentage (BF%). Associations between FFM, FM and BF% and weight/length, BMI and PI were evaluated in 1,019 newborns using multivariate regression analysis. Charts for FM, FFM and BF% were generated using a prescriptive sub-sample (n=247)...

Despite advances in psychological interventions for pediatric chronic pain, there has been little research examining mindfulness meditation for these conditions. This study presents data from a pilot clinical trial of a six-week manualized mindfulness meditation intervention offered to 20 adolescents aged 13-17 years. Measures of pain intensity, functional disability, depression and parent worry about their child's pain were obtained at baseline and post-treatment. Results indicated no significant changes in pain or depression, however functional disability and frequency of pain functioning complaints improved with small effect sizes...

Brow dermoids are benign pediatric neoplasms. Endoscopic resection requires incisions placed within the temporal hairline, which is often difficult to reliably locate in infants. The authors studied adult and pediatric patients to define the location of the hairline in relationship to simple facial landmarks. Adult and pediatric patients who were seen in preoperative consultation for facial surgical procedures were identified and included in the study. Patients with a history of facial trauma, surgery, or congenital anomalies were excluded...

Hand, foot, and mouth disease (HFMD) is a common pediatric disease caused by enterovirus infection. It typically presents as a fever along with flat, discolored spots and bumps on the hands, feet, and mouth. Compared with other viruses, enterovirus 71 (EV71)-induced HFMD is more prone to cause severe complications in children, such as brainstem encephalitis, cardiopulmonary disorders, and even death. More in-depth studies are still necessary to understand the characteristics of EV71-induced HFMD, although some related research has been reported so far...

BACKGROUND: Vitamin D and the vitamin D receptor (VDR) are important in the metabolic processes that affect bone mineral density (BMD). However, the effect of VDR BsmI polymorphism on BMD in pediatric patients is still unclear. METHODS: Eligible studies were identified from the following electronic databases: PubMed, Embase, the Cochrane Library, and the Chinese CNKI and Wanfang databases before October 1, 2016. Data were extracted from the eligible studies, and associations between VDR BsmI polymorphism and BMD in pediatric patients were estimated with weighted mean differences (WMDs) and 95% confidence intervals (CIs)...

OBJECTIVES: Sepsis is a life-threatening condition that arises when the response of the body to infection injures its own tissues and organs. The early prediction of sepsis by current clinical and laboratory methods remains inadequate. Serum neutrophil gelatinase-associated lipocalin level is increased in sepsis irrespective of renal dysfunction. Therefore, we aimed to correlate the serum neutrophil gelatinase-associated lipocalin value determined at admission with clinical progression and severity of disease in critically ill children and to declare its role as a potential diagnostic and prognostic marker for sepsis in critically ill children in the emergency department...

PURPOSE: Pediatricians' education debt has been increasing. Less is known about the pace of their debt repayment. The authors examined patterns of debt repayment for pediatricians who completed residency from 2002-2004. METHOD: The authors analyzed weighted 2013 survey data from the American Academy of Pediatrics Pediatrician Life and Career Experience Study. They categorized participants based on education debt level at residency completion ($0; $1-$49,999; $50,000-$99,999; $100,000-$149,999; ≥ $150,000) and explored debt repayment and well-being by starting debt group using multivariable logistic regression...

PURPOSE OF REVIEW: Refractive surgery procedures have been performed on children since the early 1980s. This article will review this history as well as current thoughts on treating children with large refractive errors. RECENT FINDINGS: Pediatric refractive surgery has developed slowly as very few children fit the criteria for treatment. For this reason, practice patterns are varied and publications are rare. Publications in recent years have focused on intraocular procedures over laser refractive surgery...

Thiopurines [e.g. mercaptopurine (MP)] are widely used as chemotherapeutic agents in the treatment of pediatric acute lymphoblastic leukemia with dose-limiting hematopoietic toxicity. Recently, germline variants in NUDT15 have been identified as a major genetic cause for MP-related bone marrow suppression, and there is increasing interest in the clinical implementation of NUDT15 genotype-guided MP dose individualization. Therefore, we sought to evaluate the effects of NUDT15 on thiopurine metabolism and identify pharmacologic markers to inform NUDT15 genotype-guided MP dosing...

The growing number of Spanish speakers in the United States poses communication challenges for healthcare providers. Language barriers in pediatric acute care have been associated with an increased risk for adverse events, longer hospital stays, and decreased quality of care. In addition, clinicians' usage of interpreter services is inconsistent. In fact, nurses often lack interpreter support during daily bedside care. Nursing staff at a pediatric children's hospital in the southeastern United States identified bedside communication with Spanish-speaking patients and families as a clinical challenge...
