Pediatric Non-alcoholic Fatty Liver Disease.

Childhood obesity has reached epidemic proportions, and by 2012, more than one third of American children were overweight or obese. As a result, increasingly, children are developing complications of obesity including liver disease. In fact, non-alcoholic fatty liver disease is the most common form of chronic liver disease seen in children today. Recently, there has been a burgeoning literature examining the pathogenesis, genetic markers, and role of the microbiome in this disease. On the clinical front, new modalities of diagnosing hepatic steatosis and hepatic fibrosis are being developed to provide non-invasive methods of surveillance in children. Lastly, the mainstay of treatment of pediatric non-alcoholic fatty liver disease (NAFLD) has been largely through lifestyle interventions, namely, dieting and exercise. Currently, there are a number of clinical trials examining novel lifestyle and drug therapies for NAFLD that are registered with the US National Institutes of Health ClinicalTrials.gov website.

Implementing a Novel Quality Improvement-Based Approach to Data Quality Monitoring and Enhancement in a Multipurpose Clinical Registry.

OBJECTIVE: To implement a quality improvement based system to measure and improve data quality in an observational clinical registry to support a Learning Healthcare System. DATA SOURCE: ImproveCareNow Network registry, which as of September 2019 contained data from 314,250 visits of 43,305 pediatric Inflammatory Bowel Disease (IBD) patients at 109 participating care centers. STUDY DESIGN: The impact of data quality improvement support to care centers was evaluated using statistical process control methodology. Data quality measures were defined, performance feedback of those measures using statistical process control charts was implemented, and reports that identified data items not following data quality checks were developed to enable centers to monitor and improve the quality of their data. PRINCIPAL FINDINGS: There was a pattern of improvement across measures of data quality. The proportion of visits with complete critical data increased from 72 percent to 82 percent. The percent of registered patients improved from 59 percent to 83 percent. Of three additional measures of data consistency and timeliness, one improved performance from 42 percent to 63 percent. Performance declined on one measure due to changes in network documentation practices and maturation. There was variation among care centers in data quality. CONCLUSIONS: A quality improvement based approach to data quality monitoring and improvement is feasible and effective.

Eosinophilic Gastroenteritis and Colitis: a Comprehensive Review.

Eosinophilic gastrointestinal disorders, including eosinophilic esophagitis, gastroenteritis, and colitis, refer to a spectrum of clinical diseases that present with variable degrees of infiltration of the gastrointestinal tract by eosinophils in the absence of other known causes of tissue eosinophilia. Clinical symptoms and laboratory findings are usually non-specific and may or may not be accompanied by peripheral blood eosinophilia. The extent of eosinophilic infiltration of the gastrointestinal wall varies from mucosal to transmural and serosal involvement. Diagnosis requires presence of gastrointestinal symptoms, demonstration of gastrointestinal eosinophilia by biopsy, and exclusion of other known causes of tissue eosinophilia. Many studies have pointed toward the eosinophil as the major offender; however, the exact functional role of the eosinophil in the pathogenesis of eosinophilic gastrointestinal disorders remains unclear. The roles of T-helper-2 cytokines and other mediators, such as eotaxin-1 and interleukin-5, have gained significant importance in the pathobiology of eosinophilic gastrointestinal disorders. Current understanding of treatment is based on case reports and a few case series, as there is a lack of large prospective studies. Steroids are currently the mainstay of therapy, but the roles of other drugs such as leukotriene inhibitors, mast cell stabilizers, interleukin-5 inhibitors, and anti-immunoglobulin E, along with other targets in the immune pathway, are currently being explored.
