We performed, therefore, a retrospective study 66 children with having mean age 2.85 years, comparing findings those obtained from 57 normal controls, 2.99 years. The data patients used for comparison illness, as well convalescence. performed correlation analysis phase, determining other...
The aim of the present study was to evaluate effect fluid intake on outcome treatment with osmotic laxatives, PEG 4000 and lactulose, in children chronic constipation.Medical records were reviewed, 27 constipation satisfying following criteria enrolled: (i) stable maintenance medication for ≥ 3 months; (ii) no dosage modification or drug change between two periods compared; (iii) clinical events during investigation that could affect outcomes; (iv) good compliance regarding inclusion diaries...
Each ethnic group has a unique life style, including diets. Life style affects bowel movement. The aim of this study is to describe the results colon transit time (CTT) tests in Korean children who had chronic functional constipation based on highly refined data.One hundred ninety (86 males) out 415 performed CTT test under diagnosis according Rome III criteria at Konkuk University Medical Center from January 2006 through March 2015 were enrolled study. Two hundreds twenty-five excluded...
Shwachman-Diamond syndrome (SDS) is an autosomal recessive genetic disorder, consisting of exocrine pancreatic insufficiency, chronic neutropenia, neutrophil chemotaxis defects, metaphyseal dysostosis, short stature, dental caries, and multiple organ involvements. Although SDS the second most common hereditary abnormality pancreas following cystic fibrosis in Western countries, it has rarely been reported Asia. We diagnosed a case 42-month-old girl, analysis including relatives patient...
Translationally controlled tumor protein (TCTP), a repressor for Na,K-ATPase has been implicated in the development of systemic hypertension, as proved by TCTP-over-expressing transgenic (TCTP-TG) mice. Aorta TCTP-TG exhibited hypercontractile response compared to that non-transgenic mice (NTG) suggesting dys-regulation signaling pathways involved vascular contractility TCTP. Because RhoA/Rho kinase pathway is increased contractility, we examined whether TCTP induces alterations RhoA smooth...
Purpose: To compare the clinical features, diagnostic findings, and medications of children with infrequent bowel movements or fecal soiling.Methods: This study enrolled 333 (189 male; age range, 1 month to 18 years) diagnosed functional constipation by Rome III IV criteria.We classified them into 3 groups (infrequent movement without soiling [G3-a], [G3-b], only [G3-c]) 2 subgroups (G2-b) not (G2-a).Retrospective data on characteristics, colon transit time (CTT) test results, were...
