It is important to pay attention to the indirect effects of the social distancing implemented to prevent the spread of coronavirus disease 2019 (COVID-19) pandemic on children and adolescent health. The aim of the present study was to explore impacts of a reduction in physical activity caused by COVID-19 outbreak in pediatric patients diagnosed with obesity. This study conducted between pre-school closing and school closing period and 90 patients aged between 6- and 18-year-old were included. Comparing the variables between pre-school closing period and school closing period in patients suffering from obesity revealed significant differences in variables related to metabolism such as body weight z-score, body mass index z-score, liver enzymes and lipid profile. We further evaluated the metabolic factors related to obesity. When comparing patients with or without nonalcoholic fatty liver disease (NAFLD), only hemoglobin A1c (HbA1c) was the only difference between the two time points (p < 0.05). We found that reduced physical activity due to school closing during COVID-19 pandemic exacerbated obesity among children and adolescents and negatively affects the HbA1C increase in NAFLD patients compared to non-NAFLD patients.
Intestinal lymphangiectasia is a rare disease which is causing protein-losing enteropathy. Treatment of intestinal lymphangiectasia can be a challenge for clinicians because of the lack of specific guidelines regarding pharmacological indications. We sought to introduce a diagnostic approach and suggest guidelines for treatment. After exclusion of secondary intestinal lymphangiectasia, magnetic resonance lymphangiography is a promising tool for the assessment of abnormal lymphatic lesions in primary intestinal lymphangiectasia. Determining the extent of the lesion provides direction for treatment options. Focal short-segment intestinal lymphangiectasia can be treated via intestinal resection or radiologic embolization after dietary therapy failure. Diffuse intestinal lymphangiectasia and extensive lymphangiectasia should be treated with several drugs with a full understanding of their mechanisms.
In pediatric Crohn’s disease (CD) patients, it is important to define the disease phenotype at diagnosis for stratifying risk. In this retrospective study, we aimed to assess the disease phenotype compared to EUROKIDS registry and analyze disease outcome of pediatric CD patients according to upper gastrointestinal (GI) tract involvement. A total of 312 patients were included. The median age at diagnosis was 13.7 years and 232 patients (74.4%) were identified to have upper GI involvement at diagnosis. In Korean pediatric CD patients, there were significant differences in male predominance (72.8% vs. 59.2, p < 0.001), proportion of upper GI involvement (74.4% vs. 46.2%, p < 0.001), and perianal disease (62.1% vs. 8.2%, p < 0.001) compared to data in the EUROKIDS registry. Younger age (OR 2.594, p = 0.0139) and ileal involvement (OR 2.293, p = 0.0176) at diagnosis were associated with upper GI involvement. There were no significant differences in disease outcomes between patients with and without upper GI tract involvement. This study revealed that upper GI involvement is more prevalent in Korean patients with pediatric Crohn’s disease than in European patients, and the disease outcome did not appear to differ according to upper GI tract involvement.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
