Purpose: With previous methods based on only age and location, there are many difficulties in identifying the etiology of acute abdominal pain in children. We sought to develop a new systematic classification of acute abdominal pain and to give some helps to physicians encountering difficulties in diagnoses. Methods: From March 2005 to May 2010, clinical data were collected retrospectively from 442 children hospitalized due to acute abdominal pain with no apparent underlying disease. According to the final diagnoses, diseases that caused acute abdominal pain were classified into nine groups. Results: The nine groups were group I "catastrophic surgical abdomen" (7 patients, 1.6%), group II "acute appendicitis and mesenteric lymphadenitis" (56 patients, 12.7%), group III "intestinal obstruction" (57 patients, 12.9%), group IV "viral and bacterial acute gastroenteritis" (90 patients, 20.4%), group V "peptic ulcer and gastroduodenitis" (66 patients, 14.9%), group VI "hepatobiliary and pancreatic disease" (14 patients, 3.2%), group VII "febrile viral illness and extraintestinal infection" (69 patients, 15.6%), group VIII "functional gastrointestinal disorder (acute manifestation)" (20 patients, 4.5%), and group IX "unclassified acute abdominal pain" (63 patients, 14.3%). Four patients were enrolled in two disease groups each. Conclusion: Patients were distributed unevenly across the nine groups of acute abdominal pain. In particular, the "unclassified abdominal pain" only group was not uncommon. Considering a systemic classification for acute abdominal pain may be helpful in the diagnostic approach in children.

Background: Irritable bowel syndrome (IBS), the most common functional gastrointestinal disorder, is characterized by chronic abdominal pain and bowel habit changes. Although diverse complicated etiologies are involved in its pathogenesis, a dysregulated gut-brain axis may be an important factor. Red ginseng (RG), a traditional herbal medicine, is proven to have anti-inflammatory effects and improve brain function; however, these effects have not been investigated in IBS. Methods: Three-day intracolonic zymosan injections were used to induce post-infectious human IBS-like symptoms in mice. The animals were randomized to receive either phosphate-buffered saline (CG) or RG (30/100/300 mg/kg) for 10 days. Amitriptyline and sulfasalazine were used as positive controls. Macroscopic scoring was performed on day 4. Visceral pain and anxiety-like behaviors were assessed by colorectal distension and elevated plus maze and open field tests, respectively, on day 10. Next-generation sequencing of gut microbiota was performed, and biomarkers involved in gut-brain axis responses were analyzed. Results: Compared to CG, RG significantly decreased the macroscopic score, frequency of visceral pain, and anxiety-like behavior in the IBS mice. These effects were comparable to those after sulfasalazine and amitriptyline treatments. Moreover, RG significantly increased the proliferation of beneficial microbes, including Lactobacillus johnsonii, Lactobacillus reuteri, and Parabacteroides goldsteinii. RG significantly suppressed expression of IL-1β and c-fos in the gut and prefrontal cortex, respectively. Further, it restored the plasma levels of corticosterone to within the normal range, accompanied by an increase in adrenocorticotropic hormone. Conclusion: RG may be a potential therapeutic option for the management of human IBS.

SMAD7 has been identified as a functional candidate gene for colorectal cancer (CRC). SMAD7 protein is a known antagonist of the transforming growth factor beta ($TGF-{\beta}$) signaling pathway which is involved in tumorigenesis. Polymorphisms in SMAD7 may thus alter cancer risk. The aim of this study was to investigate the influence of a SMAD7 gene polymorphism (rs2337107) on risk of CRC and clinicopathological features in an Iranian population. In total, 210 subjects including 105 patients with colorectal cancer and 105 healthy controls were recruited in our study. All samples were genotyped by TaqMan assay via an ABI 7500 Real Time PCR System (Applied Biosystems) with DNA from peripheral blood. The polymorphism was statistically analyzed to investigate the relationship with the risk of colorectal cancer and clinicopathological properties. Logistic regression analysis revealed that there was no significant association between rs2337107and the risk of colorectal cancer. In addition, no significant association between genotypes and clinicopathological features was observed (p value>0.05). Although there was not any association between genotypes and disorder, CT was the most common genotype in this population. This genotype prevalence was also higher in the patients with well grade (54.9%) and colon (72.0%) tumors. Our results provide the first evidence that this polymorphism is not a potential contributor to the risk of colorectal cancer and clinicopathological features in an Iranian population, and suggests the need of a large-scale case-control study to validate our results.

Background/Aims There has been major progress in our understanding of the irritable bowel syndrome (IBS), and novel treatment classes have emerged. The Rome IV guidelines were published in 2016 and together with the growing body of Asian data on IBS, we felt it is timely to update the Asian IBS Consensus. Methods Key opinion leaders from Asian countries were organized into 4 teams to review 4 themes: symptoms and epidemiology, pathophysiology, diagnosis and investigations, and lifestyle modifications and treatments. The consensus development process was carried out by using a modified Delphi method. Results Thirty-seven statements were developed. Asian data substantiate the current global viewpoint that IBS is a disorder of gut-brain interaction. Socio-cultural and environmental factors in Asia appear to influence the greater overlap between IBS and upper gastrointestinal symptoms. New classes of treatments comprising low fermentable oligo-, di-, monosacharides, and polyols diet, probiotics, non-absorbable antibiotics, and secretagogues have good evidence base for their efficacy. Conclusions Our consensus is that all patients with functional gastrointestinal disorders should be evaluated comprehensively with a view to holistic management. Physicians should be encouraged to take a positive attitude to the treatment outcomes for IBS patients.

Purpose: The aim of this study is to investigate the changing prevalence rate of Helicobacter pylori infection in children, of different age groups, with recurrent abdominal pain over a 10-year period. Methods: Children with recurrent abdominal pain who visited the pediatric outpatient clinic at university hospital were screened for H. pylori. Children were divided into 3 age categories of 4-5, 6-11, and 12-16 years. To study the changes in the annual prevalence rates of H. pylori infection, the study period was divided into 3 time periods: 2004-2007, 2008-2010, and 2011-2014. Urea breath test was performed for all children aged 4-16 years, with a cut-off value of 4.0‰ for children aged ${\geq}6$ years and 7‰ for children aged <6 years. Results: A total of 2,530 children (1,191 boys) with a mean age of $10.0{\pm}3.0years$ (range, 4.0-16.9 years) were included in the study. The total prevalence of H. pylori infection was 7.4% (187/2,530). The prevalence rate of H. pylori infection in children with recurrent abdominal pain was 8.0% (70/873) in 2004-2007, 7.7% (51/666) in 2008-2010, and 6.7% (66/991) in the 2011-2014. Nevertheless, a significant difference was observed in the prevalence rate between children <12 years old and ${\geq}12$ years of age (p=0.018). Conclusion: The prevalence of H. pylori infection in Korean children with recurrent abdominal pain was 7.4%, showing no significant decrease in the last 11 years; however, the prevalence rate in children <12 years old was significantly lower than that in those ${\geq}12$ years old.

I. 서 론 : 변비(便秘)는 우리가 임상에서 흔히 접하는 위장관의 증상으로서, 사람들은 배변의 횟수가 너무 적거나, 대변을 힘들게 보는 경우, 대변이 너무 딱딱하거나 양이 적은 경우 혹은 배변이 너무 고통스럽거나 불완전한 배변감이 있는 경우 등과 같이 다양한 형태로서 변비라고 생각하여 병원을 찾게 된다. 그러나 변비는 식이와 사회 및 의료 환경 등의 요인에 의해 많은 영향을 받기 때문에 변비 환자의 진단 및 치료적 접근에 앞서 이러한 다양한 인자 등을 감안하여 객관적인 표준화된 정의를 설정하는데 있어 방사선학적 진단이 유용하고 이에 관한 진단적 접근방법에 대해 알아보고자 한다. II. 본 론 : 대장의 운동기능을 평가하는 검사법 가운데 가장 기본이 되는 검사가 대장통과시간(Colon transit time, CTT) 검사이다. 대장통과시간은 만성 변비증 환자의 병태생리에 따른 유형 분류와 치료 계획의 설정에 커다란 도움을 주고 있다. 방사선 비투과성 표지자(Radiopaque marker)를 이용하는 방법, 다수 표지자 사용법(Multiple marker technique), 신티그라피 측정법(Scintigraphic measurement)이 있다. 배변조영술은 항문 직장의 해부학적 정보뿐만 아니라 배변 시 항문, 직장의 변화와 골반저의 운동상태를 파악할 수 있는 기능적 방사선학 검사이다. 배변 시 항문 직장의 역동적 관찰은 배변이상 환자의 진단 및 치료방침 결정 그리고 추적검사에 도움을 준다. 마지막으로 병력에서 빠뜨려서는 안되는 것이 행동 장애나 정서 장애와 같은 정신심리학적 요인이 동반되어 있는지를 세심하게 판단하는 것이다. 이런 경우에는 이러한 정신과적 문제와 관련된 약물 복용의 유무와 종류에 대해서도 파악을 하여야 한다. III. 결 론 : 변비의 흔한 원인에는 섬유질 섭취가 충분하지 못한 경우, 수분 섭취가 충분하지 못한 경우가 많으며, 변비환자에서의 이러한 검사의 목적은 변비의 기질적 병인을 확인하기 위함으로서, 통상 이러한 방사학적 검사를 통해 결장과 항문직장의 기능에 대한 정보를 얻을 수 있는 것은 아니다. 변비 환자의 병태생리에 따른 유형을 구분하여 향후 검사 및 치료방침을 설정하는 데 중요한 정보를 제공하고 환자의 예후를 예측하는데도 도움이 될 것으로 생각된다.
