Filter by:The aim of this study is to determine the contribution of genetic factors to the pathogenesis of diseases, including diseases such as Parkinson's disease, Hirschsprung's disease, and autism. Patient-derived cellular models of diseases will be developed, which will require the collection of blood samples from patients and healthy individuals in order to generate induced pluripotent stem cells (iPSCs) for the development of iPSC-derived human cell cultures. These human cellular models will be phenotyped using a variety of methods, including cellular, molecular, and biochemical assays. Because these human cellular models will retain the genetic background from the patients and control subjects, this will allow us to determine the contribution of genetics to disease phenotypes. Such disease-specific pluripotent stem cell lines will be invaluable tools for many basic and translational research applications, including pathophysiological studies in a developmental context, and innovation and screening of small molecule drugs capable of reversing the disease phenotype and potentially leading to a cure for a broad range of diseases, where appropriate in vitro or in vivo disease models do not exist.
Surgical procedures for complex intestinal neonatal and paediatric diseases may require the use of an ostomy, in order to discharge the upper intestine. The traditional loop ileostomy has recently be challenged by ileostomies in continuity, either the Santulli or the Bishop-Koop one, that both decompresses the proximal dilated bowel and allow intestine fluid to pass through the underlying ileal anastomosis. Nevertheless, to date, no evaluation of their indications, complications and potential benefits has been made. The aim of this study is to retrospectively compare the outcomes of loop ileostomies and ileostomies in continuity in a paediatric population. It is thus expected to better define the specific indications for these different types of ileostomies in the paediatric and neonatal population.
The overall aim is twofold: 1) to stretch the borderline regarding the present knowledge of clinical and economic cost-effectiveness of eHealth as an aid for facilitating and supporting self-management in families with long-term childhood illness, and 2) to develop a sustainable multidisciplinary research environment for advancing, evaluating, and implementing models of eHealth to promote self-management for children and their families. A number of clinical studies are planned for, covering different parts of paediatric healthcare. The concept of child-centred care is essential. Experienced researchers from care science, medicine, economics, technology, and social science will collaborate around common issues. Expertise on IT technology will analyse the preconditions for using IT; economic evaluations will be performed alongside clinical studies; and cultural and implementation perspectives will be used to analyse the challenges that arise from the changes in relations among children, family and professionals, which may occur as a result of the introduction of eHealth. Child health is not only important in itself. Investments in child health may also generate significant future gains, such as improved educational and labour market performance. Six complex, long-term and costly challenges in paediatric healthcare are planned for, involving eHealth technology such as interactive video consultation, pictures, on-line monitoring, and textual communication. The research follows an international framework for developing and evaluating complex interventions in healthcare. End-users (families) and relevant care providers (professionals in health and social care) will participate throughout the research process. The overall aim is certainly to analyse eHealth as an aid for facilitating and supporting self-management. However, the plan also includes the research issue whether eHealth at the same time improves the allocation of scarce health care- and societal resources.
This study aims to compare the outcomes of patients with long segment Hirschsprung disease or total colonic aganglionosis who had negative calretinin staining and positive ganglion cells on the proximal resection margins to those who had both positive findings.
Transition from paediatric to adult health care is crucial for preventing deterioration of chronic diseases. At present, transitional care (TC) is not established for patients with the Hirschsprung disease (H) and Anorectal Malformations (ARM). To set up a program for TC and to treat persisting symptoms in adults, data on outcome in adult patients are needed. At present such data are very limited. Therefore, we want to investigate clinical and PROM in H and ARM adolescents and adults. A cross sectional study in all H and ARM patients operated in Norway from 1970-2000 and in all adolescents operated at Oslo University Hospital from 2002-2006 will examine somatic, psychosocial and mental health, and quality of life (QoL). In children operated for H and ARM a large body of evidence shows that bowel problems, reduced QoL and impaired psychosocial and mental health are common. There are papers on sexual and urological impairment in these patients, but large studies on the topic is missing. It is a general assumption among paediatric surgeons that both somatic and mental health problems related to H and ARM improve during adolescence and adult life. Therefore, no standardized guidelines for TC in these patients have been established. Interestingly, very few studies have actually examined H and ARM patients beyond adolescence. Reports from patient organizations showing significant long-term sequels and inadequate understanding of the unique problems of H and ARM patients among health professionals treating adults. Hypothesis:H and ARM adults and adolescents have bowel, urinary and sexual difficulties and reduced QoL, psychosocial and mental health. H and ARM adults receive insufficient treatment of their chronic congenital disease. H and ARM patients with syndromes have particularly bad functional outcome. Anal dilatations and repeated rectal enemas have a negative impact on adolescent psychosocial and mental health. Main aim: Acquire knowledge about long-term bowel, urinary and sexual function, QoL and psychosocial and mental health in adult and adolescent H and ARM patients. Results: from this large study of H and ARM patients will have significant influence on treatment and follow-up, both nationally and internationally. Since very few countries except the Nordic countries have the possibility to follow patients with congenital malformations into adulthood, it is important that studies like this are done.
Background: Intestinal resections are commonly performed in the pediatric population. Perfusion of the bowel is one of the most important factors determining the viability of an intestinal anastomosis. Up to date, no ideal method to assess intestinal perfusion has proven its superiority. Objectives: Primary: The aim of this study is to establish the feasibility and impact of the use of indocyanine green technology on intestinal resection margins during elective and emergency pediatric surgeries. Secondary: The secondary outcomes of interest include collection of adverse events and difficulties encountered with the use of the indocyanine green (ICG) technology. Postoperative surgical complications will also be recorded. Study Design: An open observational clinical study will be performed by using a clinical drug (indocyanine green) and medical device (SPY Fluorescence Imaging) to assess intraoperatively intestinal perfusion in a specific pediatric population.
This study is a multi-centre, international, prospective cohort study of congenital anomalies to compare outcomes between LMICs and high-income countries (HICs) globally.
Hirschsprung's disease (HD) is a rare disease defined as a congenital absence of enteric ganglia, resulting usually in neonatal bowel obstruction. The current treatment is the operative removal of the aganglionic bowel and anastomosis to the ganglionic zone considered as 'healthy'. However, postoperative course remains unpredictable. Functional intestinal disorders are present in up to 45% of patients and can occur in the immediate postoperative period or few weeks/years later. Until now, there are neither predictive factors of postoperative digestive complications nor established treatment for postoperative dysmotility in HD. Abnormalities in enteric nervous system (ENS) phenotype and functions in the 'healthy' ganglionic segment are increasingly suspected to be directly responsible for postoperative intestinal dysfunctions in HD. Therefore, approaches aimed at restoring the nitrergic phenotype could be of major therapeutical interest. Among targets regulating the nitrergic phenotype of ENS are the microbiota and/or derived metabolites. Indeed preclinical animal models deficient in bacterial sensing molecules have a loss of nitrergic neurons and reduced colonic transit. Conversely, microbiota transfer to newborn germ-free mice restored colonic transit time. Alternatively the investigators has shown that bacterial metabolites such as short-chain fatty acids, in particular butyrate, can increase nitrergic phenotype and enhance colonic motility in a gut immaturity animal model. Therefore the investigators hypothesize preoperative butyrate enema will reduce postoperative intestinal complications at short-term and medium/long-term.
Early Check provides voluntary screening of newborns for a selected panel of conditions. The study has three main objectives: 1) develop and implement an approach to identify affected infants, 2) address the impact on infants and families who screen positive, and 3) evaluate the Early Check program. The Early Check screening will lead to earlier identification of newborns with rare health conditions in addition to providing important data on the implementation of this model program. Early diagnosis may result in health and development benefits for the newborns. Infants who have newborn screening in North Carolina will be eligible to participate, equating to over 120,000 eligible infants a year. Over 95% of participants are expected to screen negative. Newborns who screen positive and their parents are invited to additional research activities and services. Parents can enroll eligible newborns on the Early Check electronic Research Portal. Screening tests are conducted on residual blood from existing newborn screening dried blood spots. Confirmatory testing is provided free-of-charge for infants who screen positive, and carrier testing is provided to mothers of infants with fragile X. Affected newborns have a physical and developmental evaluation. Their parents have genetic counseling and are invited to participate in surveys and interviews. Ongoing evaluation of the program includes additional parent interviews.
To test the idea that submucosal endoscopy is effective and safe for endoscopic myotomy, endoscopic submucosal dissection, and access for tissue acquisition and resection. Submucosal endoscopy is a recent innovative addition to gastrointestinal endoscopy. This involves endoscopic maneuvers in the gut wall, by dissection of the submucosal layer of GI tract, thereby allowing endoscopic myotomy (incision of the muscle), endoscopic access for tissue acquisition and therapy, and resection of precancerous and cancerous gastrointestinal tissue. This approach has been a dramatic game-changer for minimally invasive management of various gastrointestinal conditions such as Zenker's diverticulum, Achalasia, Spastic Esophageal Disorders, Gastroparesis, esophageal obstruction, Hirschsprung's Disease, and Gastrointestinal neoplasia. The aim of the proposed study is to prospectively assess technical success, clinical success, and adverse events after submucosal endoscopy. Technical success will be defined as ability to successfully complete the submucosal endoscopic procedure. Clinical success will be defined as symptom relief and objective evaluation which will be assessed with radiologic imaging, repeat endoscopy, gastrointestinal motility studies, and pathology results routinely performed post-procedure for clinical care, as indicated. Adverse events will be recorded per published ASGE criteria. A database/ registry of patients undergoing submucosal endoscopic procedures will be created to demonstrate this.
