Zhengwei Li, Qingzeng Sun, Yingchun Shi
Paediatric high-grade glioma (HGG), including diffuse intrinsic pontine glioma (DIPG) are highly aggressive tumours with no effective cures. Lack of understanding of the molecular biology of these tumours, in part due to lack of well-characterized pre-clinical models, is a great challenge in the development of novel therapies. Recent studies have shown that paediatric HGG short-term cell cultures retain many of the tumour characteristics in vivo and at present one of the best choices for in-vivo experimental studies...

The aim of this work is to study pediatric pneumatic ventricle (PVAD) performance, versus VAD rate (VADR) and native heart rate (HR) ratio Rr (VADR/HR). The study uses a hybrid model of the cardiovascular system (HCS). HCS consists of a computational part (a lumped parameter model including left and right ventricles, systemic and pulmonary arterial and venous circulation) interfaced to a physical part. This permits the connection of a VAD (15 mL PVAD). Echocardiographic and hemodynamic data of a pediatric patient (average weight 14...

OBJECTIVE: Viral oral ulcers are common presentations in pediatric clinics. Although self-limiting, painful ulcerative lesions and inflamed mucosa can decrease oral intake and lead to dehydration. Despite the widespread use of Chinese herbal medicine (CHM) for pediatric upper respiratory disease in Taiwan, there is little evidence for its effectiveness as an antipyretic or in aiding ulcer healing for children with viral oral ulcers. We report two cases of children who presented with viral oral ulcers to illustrate the potential efficacy of CHM treatment in recovery from herpangina (HA) and herpetic gingivostomatitis (HGS)...

Sickle Cell Disease (SCD) is associated with episodes of severe vasocclusive pain beginning in infancy with a subset of patients with SCD transitioning to chronic pain. Response to experimental pain using Quantitative Sensory Testing (QST) in these patients suggest altered pain processing. The objectives of this study were to characterize sensitivity to multiple modalities of experimental pain stimuli and to interrogate the relationship of psychological covariates, clinical pain burden and pain-related outcomes to experimental pain sensitivity in children with SCD as compared to healthy individuals of similar age and sex...

In part 1 of this series, we discussed the historical, ethical, and legal background that provides justification for the current system of protection of subjects of human experimentation. We also discussed briefly the implementation of those principles in institutional review board (IRB) operations. In part 2, we focus on legislation dealing with pediatric research, the rules and ethics of assent, and then turn our attention to minimal-risk studies. To that end, we discuss the minimal-risk threshold and the process of balancing benefit and risk in IRB decisions for pediatric studies...

REVIEW
Carlos D Rose
As human experimentation continues to grow into an ever more complex and sophisticated endeavor, the relevant ethical and regulatory structures become more intricate. When pediatricians and general practitioners are invited by pharmaceutical companies to enroll their offices in a clinical trial or a multicenter observational study or when they develop their own research questions, they frequently find themselves at a loss in the human research environment. The legal and regulatory complexity may have an unintended deterring effect at a time when office-based high quality pediatric research is urgently needed to support evidence-based medicine...

OBJECTIVES: ATP-binding cassette subfamily C member 4 (ABCC4) encoding MRP4 protein is involved in pediatric acute lymphoblastic leukemia (ALL) drug resistance. The nonsynonymous single nucleotide polymorphism (SNP) rs2274407 (G912T; K304N) is located in the 3' splice acceptor site of exon 8 of ABCC4 pre-mRNA. The aim of this study was to investigate the prognostic value of rs2274407 in childhood ALL and its possible functional effect on MRP4. METHODS: ABCC4 G912T SNP was genotyped in 145 Iranian Philadelphia-negative (Ph(-)) children with ALL using modified tetra-primer ARMS PCR and evaluated for possible association with 3-year disease-free survival (3DFS)...

Despite extensive research in the international arena into pain and its management, there is, as yet, little research on the topic of pain in children in Saudi Arabia and in the Gulf countries generally. A systematic review was conducted to explore the impact of education programs on factors affecting paediatric nurses' postoperative pain management practice. This was done in order to advise the creation of an educational program for nurses in Saudi Arabia. Knowledge about pain, attitudes towards pain, beliefs about children's pain, perceptions of children's reports of pain, self-efficacy with regard to pain management, and perceptions of barriers to optimal practice were all considered to be relevant factors...

BACKGROUND: Diffuse intrinsic pontine gliomas (DIPGs) and high-grade astrocytomas (HGA) continue to have dismal prognoses. The combination of cetuximab and irinotecan was demonstrated to be safe and tolerable in a previous pediatric phase 1 combination study. We developed this phase 2 trial to investigate the safety and efficacy of cetuximab given with radiation therapy followed by adjuvant cetuximab and irinotecan. METHODS: Eligible patients of age 3-21 years had newly diagnosed DIPG or HGA...

Myelin oligodendrocyte glycoprotein (MOG), a member of the immunoglobulin (Ig) superfamily, is a myelin protein solely expressed at the outermost surface of myelin sheaths and oligodendrocyte membranes. This makes MOG a potential target of cellular and humoral immune responses in inflammatory demyelinating diseases. Due to its late postnatal developmental expression, MOG is an important marker for oligodendrocyte maturation. Discovered about 30 years ago, it is one of the best-studied autoantigens for experimental autoimmune models for multiple sclerosis (MS)...

Background and Objective. Anxiety/pain are experiences that make dental treatment difficult for children, especially during the time of anesthesia. Hypnosis is used in pediatric clinical situations to modify thinking, behavior, and perception as well as, recently, in dentistry; therefore the aim of this study was to evaluate the effectiveness of hypnosis combined with conventional behavior management techniques during infiltration anesthetic. Methods. Anxiety/pain were assessed with the FLACC scale during the anesthetic moment, as well as heart rate variability and skin conductance before and during the anesthetic moment, between the control and experimental group...

Neuroblastoma (NBL) is an embryonal cancer of the sympathetic nervous system (SNS), which causes 15% of pediatric cancer deaths. High-risk NBL is characterized by N-Myc amplification and segmental chromosomal gains and losses. Owing to limited disease models, the etiology of NBL is largely unknown, including both the cell of origin and the majority of oncogenic drivers. We have established a novel system for studying NBL based on the transformation of neural crest cells (NCCs), the progenitor cells of the SNS, isolated from mouse embryonic day 9...
