This was a clinical trial study to aid the recovery of elderly female alcoholic liver disease patients by providing a balanced nutritional supplement comprising soymilk. All patients gave their consent before enrolling. The average demographics of the subjects were age 81.57 years, height 150.43 cm, weight 52.67 kg, and body mass index 24.15 kg/m2 . An increase in the daily consumption of fruits and fruit juice was observed after the patients had started taking the balanced meal as compared to before. Intakes of vitamin A, vitamin C, vitamin E, and cholesterol decreased after consuming soymilk, whereas vitamin B 12, niacin, folic acid, and dietary fiber significantly increased (P<0.05). Blood cholesterol and BUN levels showed a decreasing tendency.Our results indicate that consuming soymilk in a balanced diet for female patients afflicted with alcoholic liver disease helps improve their nutritional status by increasing the nutrients lacking in the body.

Fecal microbiota transplantation (FMT) is a highly efficacious and safe modality for the treatment of recurrent or refractory Clostridioides difficile infection (CDI), with overall success rates of 90%. Thus, FMT has been widely used for 10 years. The incidence and clinical characteristics of CDI, the main indication for FMT, differ between countries. To date, several guidelines have been published. However, most of them were published in Western countries and therefore cannot represent the Korean national healthcare systems. One of the barriers to performing FMT is a lack of national guidelines. Accordingly, multidisciplinary experts in this field have developed practical guidelines for FMT. The purpose of these guidelines is to aid physicians performing FMT, which can be adapted to treat CDI and other conditions.

Background/Aims: The mucoprotective drug rebamipide is used to treat gastritis and peptic ulcers. We compared the efficacy of Mucosta Ⓡ (rebamipide 100 mg) and its new formulation, AD-203 (rebamipide 150 mg), in treating erosive gastritis. Methods: This double-blind, active control, noninferiority, multicenter, phase 3 clinical trial randomly assigned 475 patients with endoscopically proven erosive gastritis to two groups: AD-203 twice daily or Mucosta Ⓡ thrice daily for 2 weeks. The intention-to-treat (ITT) analysis included 454 patients (AD-203, n=229; Mucosta Ⓡ , n=225), and the per-protocol (PP) analysis included 439 patients (AD-203, n=224; Mucosta Ⓡ , n=215). The posttreatment assessments included the primary (erosion improvement rate) and secondary endpoints (erosion and edema cure rates; improvement rates of redness, hemorrhage, and gastrointestinal symptoms). Drug-related adverse events were evaluated. Results: According to the ITT analysis, the erosion improvement rates (posttreatment) in AD-203-treated and Mucosta Ⓡ -treated patients were 39.7% and 43.8%, respectively. According to the PP analysis, the erosion improvement rates (posttreatment) in AD-203-treated and Mucosta Ⓡ -treated patients were 39.3% and 43.7%, respectively. The one-sided 97.5% lower limit for the improvement rate difference between the study groups was −4.01% (95% confidence interval [CI], –13.09% to 5.06%) in the ITT analysis and −4.44% (95% CI, –13.65% to 4.78%) in the PP analysis. The groups did not significantly differ in the secondary endpoints in either analysis. Twenty-four AD-203-treated and 20 Mucosta Ⓡ -treated patients reported adverse events but no serious adverse drug reactions; both groups presented similar adverse event rates. Conclusions The new formulation of rebamipide 150 mg (AD-203) twice daily was not inferior to rebamipide 100 mg (Mucosta Ⓡ ) thrice daily. Both formulations showed a similar efficacy in treating erosive gastritis.

Methanol poisoning is a medical emergency that requires rapid elimination of the toxin and its metabolites for recovery. The danger of methanol results from the accumulation of its toxic metabolite formic acid. This accumulation may result in the development of metabolic acidosis, visual impairment, and damage to the basal ganglia. Extracorporeal treatment is recommended in severe cases of methanol poisoning with coma, seizure, new vision deficits, metabolic acidosis, high serum anion gap, elevated methanol concentrations or impaired kidney function. Although the serum methanol concentration is helpful in determining the use of extracorporeal treatment, methanol assays are not standard laboratory tests in Korea. Herein, we report a case of methanol poisoning in which the patient's clinical improvement was confirmed using serum and urine methanol levels.

BACKGROUND/AIMS: Establishment of a colonoscopy reporting system is a prerequisite to determining and improving quality. This study aimed to investigate colonoscopists' opinions and the actual situation of a colonoscopy reporting system in a clinical practice in southeastern area of Korea and to assess the factors predictive of an inadequate reporting system. METHODS: Physicians who performed colonoscopies in the Daegu-Gyeongbuk province of Korea and were registered with the Korean Society of Gastrointestinal Endoscopy (KSGE) were interviewed via mail about colonoscopy reporting systems using a standardized questionnaire. RESULTS: Of 181 endoscopists invited to participate, 125 responded to the questionnaires (response rate, 69%). Most responders were internists (105/125, 84%) and worked in primary clinics (88/125, 70.4%). Seventy-one specialists (56.8%) held board certifications for endoscopy from the KSGE. A median of 20 colonoscopies (interquartile range, 10–47) was performed per month. Although 88.8% of responders agreed that a colonoscopy reporting system is necessary, only 18.4% (23/125) had achieved the optimal reporting system level recommended by the Quality Assurance Task Group of the National Colorectal Cancer Roundtable. One-third of endoscopists replied that they did not use a reporting document for the main reasons of "too busy" and "inconvenience." Non-endoscopy specialists and primary care centers were independent predictive factors for failure to use a colonoscopy reporting system. CONCLUSIONS: The quality of colonoscopy reporting systems varies widely and is considerably suboptimal in actual clinical practice settings in southeastern Korea, indicating considerable room for quality improvements in this field.

PURPOSE: Stem cell-based therapies represent new promises for the treatment of urinary incontinence. This study was performed to assess optimized cell passage number, cell dose, therapeutic efficacy, feasibility, toxicity, and cell trafficking for the first step of the pre-clinical evaluation of human amniotic fluid stem cell (hAFSC) therapy in a urinary incontinence animal model. MATERIALS AND METHODS: The proper cell passage number was analyzed with hAFSCs at passages 4, 6, and 8 at week 2. The cell dose optimization included 1x10(4), 1x10(5), and 1x10(6) cells at week 2. The in vivo cell toxicity was performed with 0.25x10(6), 0.5x10(6), and 1x10(6) cells at weeks 2 and 4. Cell tracking was performed with 1x10(6) cells at weeks 2 and 4. RESULTS: The selected optimal cell passage number was smaller than 6, and the optimal cell dose was 1x10(6) for the mouse model. In our pre-clinical study, hAFSC-injected animals showed normal values for several parameters. Moreover, the injected cells were found to be non-toxic and non-tumorigenic. Furthermore, the injected hAFSCs were rarely identified by in vivo cell trafficking in the target organs at week 2. CONCLUSION: This study demonstrates for the first time the pre-clinical efficacy and safety of hAFSC injection in the urinary incontinence animal model and provides a basis for future clinical applications.

Despite recent advances in understanding of the pathobiology and targeted treatments of pulmonary arterial hypertension (PAH), epidemiologic data from large populations have been limited to western countries. The aim of the Korean Registry of Pulmonary Arterial Hypertension (KORPAH) was to examine the epidemiology and prognosis of Korean patients with PAH. KORPAH was designed as a nationwide, multicenter, prospective data collection using an internet webserver from September 2008 to December 2011. A total of 625 patients were enrolled. The patients' mean age was 47.6 +/- 15.7 yr, and 503 (80.5%) were women. The diagnostic methods included right heart catheterization (n = 249, 39.8%) and Doppler echocardiography (n = 376, 60.2%). The etiologies, in order of frequency, were connective tissue disease (CTD), congenital heart disease, and idiopathic PAH (IPAH) (49.8%, 25.4%, and 23.2%, respectively). Patients with WHO functional class III or IV at diagnosis were 43.4%. In total, 380 (60.8%) patients received a single PAH-specific treatment at the time of enrollment, but only 72 (18.9%) patients received combination therapy. Incident cases during the registry represented 297 patients; therefore, the incidence rate of PAH was 1.9 patients/yr/million people. The 1st-, 2nd-, and 3rd-yr estimated survival rates were 90.8%, 87.8%, and 84.4%, respectively. Although Korean PAH patients exhibited similar age, gender, and survival rate compared with western registries, they showed relatively more CTD-PAH in the etiology and also systemic lupus erythematosus among CTD-PAH. The data suggest that earlier diagnosis and more specialized therapies should be needed to improve the survival of PAH patients.

PURPOSE: Upper gastrointestinal bleeding (UGIB) is one of the most common causes of emergency department (ED) presentation which can lead to a fatal condition. Many clinical scoring systems intended to predict the prognosis of UGIB patients were developed and validated, including Glasgow-Blatchford score (GBS) and Rockall score (RS). In particular, GBS has shown its superiority in prediction of mortality, the necessity of endoscopic intervention and admission, compared with other scoring systems, in recent studies. However, GBS does not include the age of the patient as its component and has clearly shown its efficacy only in subjects under age 70. Hence, we aimed to assess whether GBS could also be used in old age UGIB patients as a useful risk stratifying method as in younger age. METHODS: UGIB patients who visited our ED for one year were retrospectively enrolled in the analysis. Medical records of the subjects were reviewed, and their GBS and clinical RS were calculated. Receiver-operating characteristics (ROC) curve of each score in prediction of high risk UGIB was drawn and area under curve (AUC) was calculated. Correlation analysis of each score and hospital length of stay was also performed. To assess the validity of each score for use in old age patients, all analyses were also performed in subgroups of age over 60 years, and under that. RESULTS: ROC curves suggest that GBS has significant detecting power for high risk UGIB in overall subjects, subgroups of age over 60 and under (p=<0.001 for all, AUC=0.919, 0.935, 0.901, respectively). Otherwise, clinical RS only showed significant results in overall group and subgroup of age over 60 with lower AUC. CONCLUSION: GBS may also be used safely as an initial risk stratifying method in old age UGIB patients visiting the ED, as in other age groups.

BACKGROUND/AIMS: Advances in endoscopic submucosal dissection (ESD) techniques have led to the development of expanded criteria for endoscopic resection of early gastric cancer (EGC). The aim of this study was to evaluate the short- and long-term outcomes for ESD using indication criteria. METHODS: A total of 1,105 patients underwent ESD for EGC at six medical centers. The patients were classified into the following two groups based on the lesion size, presence of ulceration and pathological review: an absolute criteria group (n=517) and an expanded criteria group (n=588). RESULTS: The curative resection rates (91.1% vs 91.3%, p=0.896) were similar in the absolute criteria group and the expanded criteria group. The en bloc resection rates (93.4% and 92.3%, respectively; p=0.488) and complete resection rates (98.3% and 97.4%, respectively; p=0.357) did not differ between the groups. The cumulative disease-free survival rates and the overall survival rates were similar between the groups (p=0.778 and p=0.654, respectively). Independent factors for the curative resection of EGC included tumor location (upper vs middle and lower, 2.632 [1.128-6.144] vs 3.497 [1.560-7.842], respectively) and en bloc resection rate 12.576 [7.442-21.250]. CONCLUSIONS: The expanded criteria for ESD in cases of EGC is comparable with the widely accepted pre-existing criteria.
