Study on relationship between self-recognition of voice disorder and mental health status: Korea National Health and Nutrition Examination Survey.

Background: The voice has been thought to be associated with emotions, but conducting large-scale research on this relationship has some limitations. To overcome these limitations, questionnaires have been utilized as a research tool.

Methods: A population-based cross-sectional study was done.

Volume of hospital is important for the prognosis of high-risk patients with nonvariceal upper gastrointestinal bleeding (NVUGIB).

Background And Aim: Nonvariceal upper gastrointestinal bleeding (NVUGIB) is a potentially life-threatening hospital emergency requiring hemodynamic stabilization and resuscitation. This study is carried out to determine whether hospital volume can influence outcome in patients with NVUGIB.

Method: This is a retrospective study with a prospective cohort database (KCT 0000514.

Progressive loss of nigrostriatal dopaminergic neurons induced by inflammatory responses to fipronil.

Inflammatory responses are involved in mechanisms of neuronal cell damage in the pathogenesis of neurodegenerative diseases such as Parkinson's disease (PD). We investigated the mechanisms whereby inflammatory responses contribute to loss of dopaminergic neurons in fipronil (FPN)-treated rats. After stereotaxic injection of FPN in the substantia nigra (SN), the number of tyrosine hydroxylase (TH)-positive neurons and the levels of TH expression in the SN decreased at 7days, and a significant decrease was observed at 14days with a subsequent reduction in striatal TH expression.

The Novel Scoring System for 30-Day Mortality in Patients with Non-variceal Upper Gastrointestinal Bleeding.

Background: Although the mortality rates for non-variceal upper gastrointestinal bleeding (NVUGIB) have recently decreased, it remains a significant medical problem.

Aim: The main aim of this prospective multicenter database study was to construct a clinically useful predictive scoring system by using our predictors and compare its prognostic accuracy with that of the Rockall scoring system.

Methods: Data were collected from consecutive patients with NVUGIB.

[Comparison between Endoscopic Therapy and Medical Therapy in Peptic Ulcer Patients with Adherent Clot: A Multicenter Prospective Observational Cohort Study].

Background/aims: The optimal management of bleeding peptic ulcer with adherent clot remains controversial. The purpose of this study was to compare clinical outcome between endoscopic therapy and medical therapy. We also evaluated the risk factors of rebleeding in Forrest type IIB peptic ulcer.

[Comparison on Endoscopic Hemoclip and Hemoclip Combination Therapy in Non-variceal Upper Gastrointestinal Bleeding Patients Based on Clinical Practice Data: Is There Difference between Prospective Cohort Study and Randomized Study?].

Background/aims: Endoscopic hemoclip application is an effective and safe method of endoscopic hemostasis. We conducted a multicenter retrospective study on hemoclip and hemoclip combination therapy based on prospective cohort database in terms of hemostatic efficacy not in clinical trial but in real clinical practice.

Methods: Data on endoscopic hemostasis for non-variceal upper gastrointestinal bleeding (NVUGIB) were prospectively collected from February 2011 to December 2013.

Comparison of scoring systems for nonvariceal upper gastrointestinal bleeding: a multicenter prospective cohort study.

Background And Aim: The Glasgow-Blatchford score (GBS) and Rockall score (RS) are widely used to assess risk in patients with upper gastrointestinal bleeding (UGIB). We compared both scoring systems and evaluated their clinical usefulness.

Methods: Between February 2011 and December 2013, 1584 patients with nonvariceal UGIB were included in the study.

Meloxicam inhibits fipronil-induced apoptosis via modulation of the oxidative stress and inflammatory response in SH-SY5Y cells.

Oxidative stress and inflammatory responses have been identified as key elements of neuronal cell apoptosis. In this study, we investigated the mechanisms by which inflammatory responses contribute to apoptosis in human neuroblastoma SH-SY5Y cells treated with fipronil (FPN). Based on the cytotoxic mechanism of FPN, we examined the neuroprotective effects of meloxicam against FPN-induced neuronal cell death.

A case of intrapancreatic accessory spleen mistaken as a pancreatic mass due to different enhancing pattern from normal spleen.

Most cases of accessory spleen show similar features as normal spleen in imaging studies. However, some accessory spleen has unusual scan feature which can be misdiagnosed. We present a case of intrapancreatic accessory spleen that was discovered incidentally during a workup for abdominal pain in a 47-year-old woman.

Appropriate indications for endoscopic submucosal dissection of early gastric cancer according to tumor size and histologic type.

Background: Endoscopic submucosal dissection (ESD) is increasingly being performed for early gastric cancers (EGCs) that are larger than 2 cm and those that are not intestinal-type (IT) cancers by Lauren's classification. The technical feasibility of ESD for these EGCs has not been fully evaluated.

Objective: To identify appropriate expanded indications for ESD of EGC.

Inter-observer agreement on the interpretation of capsule endoscopy findings based on capsule endoscopy structured terminology: a multicenter study by the Korean Gut Image Study Group.

Objective: Capsule endoscopy (CE) is a novel investigation for the diagnosis of small-bowel disease but its interpretation is highly subjective. We studied the inter-observer agreement and accuracy of the interpretation of CE findings based on capsule endoscopy structured terminology (CEST).

Material And Methods: Fifty-six CE video clips were collected from eight university hospitals in South Korea and were independently reviewed by 13 gastroenterology experts and 10 trainees.
