Digital rectal examination (DRE) is a simple clinical method to diagnose anorectal disorders. High-resolution antorectal manometry (HRAM) based on spatiotemporal plot expected promote improved diagnostic accuracy. However, there are no reports comparing the effectiveness of DRE and HRAM. The aim our study was therefore evaluate value compared with HRAM.A total 309 consecutive patients chronic constipation (n=268) or fecal incontinence (n=41) who underwent standardized DRE, HRAM, balloon...
Cardiovascular disease (CVD) is one of the main causes mortality worldwide, and dyslipidemia a major risk factor for CVD. Ginseng has been widely used in clinic to treat Ginsenoside Rg3, active components ginseng, reported exhibit antiobesity, antidiabetic, cardioprotective effects. However, effect ginsenoside Rg3 on hepatic lipid metabolism remains unclear. Therefore, we investigated whether would regulate with AMP-activated protein kinase (AMPK) activation HepG2 cells. significantly...
Mobile health (mHealth), a term used for healthcare delivery via mobile devices, has gained attention as an innovative technology better access to and support performance of workers in the global context. Despite large expansion mHealth across sub-Saharan Africa, regional collaboration scale-up not made progress since last decade.As groundwork strategic planning collaboration, study attempted identify spatial patterns implementation Africa using exploratory data analysis. In order obtain...
Background and aims: No previous large-scale studies have evaluated the prognosis of ulcerative colitis (UC) over a period three decades in non-Caucasian population. The aims this study were to update current information on natural course UC sizable cohort Korean patients evaluate changes treatment paradigms time. Methods: We retrospectively analyzed 2802 who visited Asan Medical Center. divided subjects into groups based year diagnosis (cohort 1: 1977–1999; 2: 2000–2006; 3: 2007–2013)....
In South Korea, tuberculosis (TB) is still prevalent, but its incidence has been decreasing.On the other hand, and prevalence of Crohn's disease (CD) increasing as in many Asian countries.In this paper, we demonstrated inverse trends misdiagnosis rates between CD intestinal TB (ITB) over last two decades.That is, cases misdiagnosed initially ITB have decreasing, whereas increasing.More attention needed for correct diagnosis or ITB, which could improve patients' outcomes with proper management.
The objective of this study was to assess the validity and reliability Korean version chronic obstructive pulmonary disease assessment test (CAT) Dyspnea-12 Questionnaire for patients with bronchiectasis or tuberculous destroyed lung.For 62 37 lung patients, 3 questionnaires including St. George's Respiratory Questionnaires (SGRQ), CAT, were obtained, in addition spirometric measurements. To CAT Dyspnea-12, correlation SGRQ evaluated. Cronbach's α coefficient calculated.The mean ages...
Objective. Limited data are available on the incidence and risk factors of colorectal cancer (CRC) in Asian patients with inflammatory bowel disease (IBD). Material methods. Information 5212 Korean IBD (2414 Crohn's [CD] 2798 ulcerative colitis [UC]) was retrieved from registry Asan Medical Center. Data CRC for entire population were derived Statistical Service. Results. During 39,951 person-years follow-up (17,679 CD 22,272 UC), 30 (12 18 UC) developed CRC. The standardized ratio (SIR) 6.0...
Background: The object of this study was to assess the validity and reliability Korean versions chronic obstructive pulmonary disease assessment test (CAT) Dyspnea-12 Questionnaire for patients with (COPD).Methods: For 127 COPD patients, we obtained 3 questionnaires being tested: St George's Respiratory (SGRQ), CAT, spirometric measurements.To CAT Dyspnea-12, their correlation SGRQ evaluated.To Cronbach's alpha coefficient evaluated.Results: mean age patient participants 68.6±7.5 years;...
Background/Aims We attempted to investigate the prognosis of signet-ring cell carcinoma (SRC) patients who underwent curative surgery by comparing them with age-, sex-, and stage-matched non-mucinous adenocarcinoma (NMAC) patients. Methods Between January 2003 December 2011, 19 primary SRC colorectum surgery. Four under age 40 were excluded, clinicopathological data 15 (7 men; median age, 56 years) reviewed compared 75 NMAC matched sex, pathologic stage. Results The follow-up duration was...
Abstract Background Recently mobile health (mHealth) has been implemented in Kenya to support family planning. Our objectives were investigate disparities phone ownership and examine the associations between exposure planning messages through mHealth (stand-alone or combined with other channels such as public forums, informational materials, workers, social media political/religious/community leaders’ advocacy) contraceptive knowledge use. Methods Logistic Poisson regression models used...
No previous studies have evaluated the long-term outcomes of acute severe ulcerative colitis (ASUC) in non-Caucasian populations. The purposes this study were to evaluate short- and Korean patients with ASUC.We retrospectively analyzed 99 ASUC who satisfied criteria given by Truelove Witts between 1999 2005. short-term outcome parameter was colectomy rate during index hospitalization, parameters rates rehospitalization after discharge from hospitalization.During 16 (16.2%) underwent...
Appendectomy protects against the development of ulcerative colitis (UC). However, relationship between appendectomy and clinical course UC is complex, could be impacted by a number variables. The aim this study was to compare appendectomized patients nonappendectomized in Korea.Data on 2648 were retrieved from Inflammatory Bowel Disease registry at Asan Medical Center. This retrospective cohort compared 68 who received an before their diagnosis 2544 did not receive procedure. A nested...
As an innovative solution to poor access care in low- and middle-income countries (LMICs), m-health has gained wide attention the past decade.Despite enthusiasm from global health community, LMICs have not demonstrated high uptake of promoting policies or public investment.To benchmark current status, this study compared policy readiness scores between sub-Saharan Africa high-income Organization for Economic Cooperation Development (OECD) using independent two-sample t test. In addition,...
Endoscopic ultrasound-guided fine needle aspiration and/or biopsy (EUS-FNA/B) have been used to diagnose subepithelial tumors (SETs) and extraluminal lesions in the gastrointestinal tract. Our group previously reported usefulness of EUS-FNA/B for rectal perirectal lesions. This study reports our expanded experience with terms diagnostic accuracy safety. We also included new EUS-FNB using recently introduced ProCore needle.From April 2009 March 2014, was performed 30 consecutive patients....
