Background/Aims Functional dyspepsia (FD) is one of the most common gastrointestinal disorders, and FD imposes social and economic burden worldwide. The aim of this study is to identify the prevalence and risk factors of FD in health check-up population in tertiary centers in Korea. Methods A nationwide multicenter prospective study was performed at 9 tertiary healthcare centers in Korea between September 2016 and June 2017. A total of 2525 subjects were investigated based on endoscopic findings and questionnaires with the Rome III criteria, and Helicobacter pylori serology (IgG). Results A total of 1714 subjects without organic disease were enrolled. The mean (${\pm}SD$) age was 51.5 (${\pm}12.7$) years, and 917 patients (53.5%) were female. The proportion of H. pylori seropositivity was 51.0% (874/1714). The prevalence of FD was 10.3% (176/1714), and the subtypes of postprandial distress syndrome alone, epigastric pain syndrome alone, and postprandial distress syndromeepigastric pain syndrome overlap were 4.8%, 3.0%, and 2.5%, respectively. Multivariate analysis showed that female gender (OR, 1.58; 95% CI, 1.14-2.21) and education below college level (OR, 1.45; 95% CI, 1.01-2.07) were related to FD. Multivariate analysis based on age 60 showed female gender as a significant (OR, 2.90; 95% CI, 1.06-7.94) factor in the group ${\geq}60$ years. Conclusions The prevalence of FD was 10.3% in the health check-up population in Korea. Female sex and education below college level were risk factors for FD. Female sex is a risk factor for FD in old age, underscoring the need for close attention in this age group.

스트레스가 위장관 기능을 변화시키며 이에는 interleukin과 시상하부-뇌하수체-부신피질 축이 관여한 다고 알려져 있다. 한편 우울증이 기능성 위장관 장애 및 interleukin과 연관성을 지닌다. 본 연구에서는 IL-$1\beta$, IL-2, IL-6의 혈청 농도를 기능성 위장관 장애 환자에서 측정하고, 혈청 cortisol 및 우울증과 스트레스의 정도를 조사하여 기능성 위장관 장애에 있어서 interleukin의 역할과 우울증 및 스트레스와의 상관성을 살펴보고자 하였다. 방법: 기능성 위장관 장애의 진단을 위한 로마기준 II에 따라 진단된 환자 20명과 건강한 대조군 20명을 대상으로 하였다. 채취한 혈액에서 혈청을 분리한 다음 Enzyme-linked Immunosorbent Assay 방법으로 혈청 IL-$1\beta$, IL-2, IL-6 농도를 측정하고 Fluorescence Polarization Immunoassay 방법으로 혈청 cortisol 농도 를 측정하였다. 우울증상의 정도를 Hamilton Rating Scale for Depression을 이용하여 평가하고, Schedule of Recent Experience를 이용하여 최근 일년간의 스트레스 생활사건의 양을 측정하여 비교하였다. 결과는 다음과 같다. 결과: 1) 기능성 위장관 장애 환자들의 혈청 IL-$1\beta$, IL-2 농도는 대조군에 비해 유의하게 낮았으나 혈청 IL-6 농도는 차이가 없었다. 2) 기능성 위장관 장애 환자군의 혈청 cortisol 농도는 대조군에 비해 유의하게 높았고, 우울증상도 유의하게 더 심하였으며, 스트레스 생활사건의 양 또한 유의하게 더 많았다. 3) 기능성 위장관 장애에서 우울증상의 정도와 혈청 cortisol 간에는 유의한 정상관관계가 있었다. 정도는 IL-$1\beta$와 역상관하는 경향이 있고, IL-2와는 정상관하였다. 스트레스 생활사건의 양파 혈청 cortisol 농도는 IL-6 와 유의하게 정상관하였다 대조군을 포함한 전 집단에서 IL-$1\beta$는 우울 정도, 스트레스 생활사건의 양, 혈청 cortisol 등과 유의하게 역 상관하였다. IL-6와 의하게 정상관하였다. 결론: 기능성 위장관 장애는 우울증 및 스트레스와 연관되며, 우울증, 스트레스가 심할수록 혈청 cortisol이 높았다. 기능성 위장관 장애 환자들에서 IL-$1\beta$, IL-2가 감소되어 있었지만, IL-6는 변화가 없었다. 상대적으로 증가된 혈청 cortisol이 IL의 변화와 관련될 수 있다고 생각된다.

연구목적: 구조적 변화를 동반하는 염증성장질환(inflammatory bowel disease)과 이를 동반하지 않는 기능성위장관질환(functional gastrointestinal disorder)의 정신병리를 비교하기 위한 많은 연구가 진행되어 왔으며, 최근에는 감정표현불능증과 이들 질환과의 관련성에 대한 많은 연구가 있었으나, 지금까지의 비교 연구는 타당도가 인정된 척도의 부족과 기능성위장관질환의 진단의 혼란으로 결과의 분석에 한계가 있었다. 따라서 본 연구에서는 이 두 가지 문제점을 보완하여 감정표현불능증의 정도를 비교 분석하고, 전반적 인격적 특성이나 기타 정신병리도 비교 분석하고자 하였다. 방 법: 경북대학교 병원 내과에서 대장 내시경과 조직 검사를 통해서 확진되어 치료중인 궤양성대장염 환자 28명과, 기능성위장관질환의 국제 분류(Rome II Classification)의 진단 기준에 부합하는 과민성대장증후군 환자 27명과, 대조군 30명을 대상으로 타당도가 증명된 한국판 20항목 Toronto 감정표현불능증 척도(Korean Version of the 20-Item Alexithymia Scale, 이하 TAS-20K), Rorschach 검사, MMPI 검사를 실시하였다. 결 과: 조사된 궤양성대장염 환자의 25%와 과민성대장증후군환자의 22%에서 감정표현불능증이 있는 것으로 보였으나 대조군에서는 모두 정상 범위에 속했다. Rorschach 검사 결과 색채반응의 가중치총합(weighted Sum C)과 경험실제(EA)수치가 과민성대장증후군 환자에서 높았다. MMPI 검사 결과 궤양성대장염 환자와 과민성대장증후군 환자에서 대조군에 비해 다양한 임상 척도의 증가와 낮은 자아강도 척도를 보였으나 두 질환 군 사이에 통계적으로 유의한 차이는 없었다. 결 론: 궤양성대장염환자와 과민성대장증후군 환자 두 군 모두 대조군에 비해 감정표현불능증의 유병률이 높으며 전반적인 정신병리의 수준이 높고 낮은 자아강도를 보이나, 이들 두 군 사이의 차이는 없었다.

Lactic acid bacteria had been widely utilized in fermented foods such as fermented dairy products, traditional sauces, kimchi, fermented sausages, medicines or probiotic feed additives for a long time. LAB are also widely distributed in the mammalian gastrointestinal tracts, oral cavity, vagina, and various foods or soils. The most familiar examples of using LAB would be the fermented milk products, and those had become one of the favorite foods in Korea f3r more than 34 years of history. The main benefits of the fermented milk products were originally the improvement of the balance of intestinal flora to control diarrhea and congestion disorders, and gradually, they were chosen by the consumer preference of the taste. The very beginning of the fermented milk products in Korea was the Yakult type products in 1971, and it was the commencement of the solid foundation of the dairy industry and the understanding beneficial effect of probiotic yogurt. After middle of 80's, stirred type fermented milk products had been firstly produced, and it was the time that the domestic dairy industry took root in Korea. From 90's, functional fermented milk products were produced, and drink type yogurt sales a mount increased drastically, and these products began to be chosen not only with the values of nutrition but also with physiological functions. The health claims are classified into intestinal health, gastric health and hepatic health. The prospects for the Korean market are as follows; The majority of leading products would be the premium functional yogurt products as it was last year. It is because the sales of lower cost products shows slow-down, and industries tend to increase the commercial advertisements of premium functional yogurt products through mass media. These tendencies would make the market situation become more competitive.

Purpose: Clinical symptoms associated with Clostridium difficile infection (CDI) can vary widely. Carrier state without apparent symptoms is relatively common during infancy. The objective of this study was to determine the association of C. difficile colonization with bowel habit change and the effect of C. difficile colonization treatment on restoration of normal bowel habit. Methods: Between 2006 and 2014, infants at 1 to 12 months of age with diarrhea for more than 2 weeks who did not improve with conservative care were recruited from Gachon University Gil Medical Center. Infants who were followed up for at least 7 days were included. The presence or absence of C. difficile colonization, effect of metronidazole, and other medical records were reviewed. To determine the association between CDI and bowel habit change, logistic regression analysis was used. Results: Of a total of 126 infants, 74 (58.7%) were male patients. Of the 126 patients, 27 (21.4%) had C. difficile colonization. Significant (p<0.05) risk factors for C. difficile colonization included artificial milk feeding (odds ratio [OR], 4.310; 95% confidence interval [CI], 1.564-11.878), prior rotavirus vaccination (OR, 4.322; 95% CI, 1.018-18.349), and antibiotic use (OR, 4.798; 95% CI, 1.430-16.101). There was improvement in bowel habit after metronidazole therapy (OR, 0.34; 95% CI, 0.15-0.79; p<0.05), regardless of the presence or absence of C. difficile colonization, Conclusion: There was no significant correlation between bowel habit change and C. difficile colonization during infancy. However, metronidazole can be used as an optional method to manage functional gastrointestinal disorders.

Purpose: Infant regurgitation is associated with other functional gastrointestinal disorders and signs and symptoms that have a major impact on the quality of life of infants and their families. This study evaluated the safety, tolerance, and real-world effectiveness of an anti-regurgitation formula containing locust bean gum (LBG), prebiotics, and postbiotics to alleviate digestive symptoms beyond regurgitation. Methods: This 3-month study involved infants with regurgitation requiring the prescription of an anti-regurgitation formula according to usual clinical practice. Outcomes included evaluation of the evolution of stool consistency and frequency; occurrence of colic, constipation, and diarrhea; and assessment of regurgitation severity. Infant crying, parental assessment of infant well-being, and parental satisfaction with the stool consistency were also evaluated. Results: In total, 190 infants (average age: 1.9±1.1 months) were included. After three months, stool frequency and consistency remained within the normal physiological range, with 82.7% of infants passing one or two stools per day and 90.4% passing loose or formed stools. There was no significant increase in the number of infants with diarrhea, whereas a decrease was observed in the number of infants with constipation after 1 month (p=0.001) and with colic after both 1 and 3 months (p<0.001). Regurgitation severity and crying decreased and parental satisfaction with stool consistency, formula acceptability, infant well-being, and sleep quality increased. Monitoring of adverse events did not reveal any safety concerns. Conclusion: Formulas containing LBG, prebiotics, and postbiotics were well tolerated and provided an effective strategy for managing infant regurgitation and gastrointestinal discomfort.

목 적: H. pylori는 만성 위염의 중요한 원인균으로서 이에 대한 많은 연구가 진행되었지만 이와 관련된 기능성 소화불량과의 관계나 위 운동에 미치는 영향에 대한 연구는 특히 소아에서 많지 않다. 이에 본 연구자들은 소아 및 청소년의 기능성 소화불량 환자에서 H. pylori 감염이 위전도 검사 결과에 미치는 영향을 평가하고자 하였다. 방 법: 2006년 8월부터 2008년 12월까지 복통을 주소로 가천의대 길병원과 인하대병원 소아청소년과에 소화불량을 주소로 내원한 소아 및 청소년 중 상부 위장관 내시경 검사와 함께 조직검사 혹은 요소호기 검사를 시행한 환아 중 기능성 소화불량 환자를 대상으로 위전도 검사를 시행하였다. 이 중 조직검사를 통해 만성 위염이 확인되고 만성 질환자를 제외한 63예를 대상으로 H. pylori 양성군과 음성군으로 나누어 위전도 검사 결과를 비교 분석하였다. 결 과: H. pylori 양성군은 25명(40%)이었으며 음성군은 38명(60%)이었다. H. pylori 양성군에서 음성군보다 식, 전후 정상리듬의 비율이 비교적 낮았다(80% vs. 65%, 80% vs. 68%). 또한 주 힘은 식후 검사상 H. pylori 양성군에서 유의하게 낮았으며(8.18${\pm}$22.36 dB, 32.20${\pm}$24.18 dB, p<0.01), 식후 주 힘의 변화(${\delta}P$)도 유의하게 적었다(-1.28${\pm}$6.18 vs. +4.62${\pm}$5.93, p<0.01). 그러나 다른 변수들은 유의미한 차이를 보이지 않았다. 결 론: H. pylori 감염은 위의 운동에 영향을 미치는 것으로 생각되며, 따라서 H. pylori 감염과 함께 위 운동 이상이 있을 경우 H. pylori 감염률이 낮은 지역에서는 H. pylori 제균 치료를 고려할 수도 있을 것으로 생각한다.

Although functional gastrointestinal disorders (FGIDs) are very common in pediatric patients, there is a scarcity of published epidemiologic data, characteristics, and management patterns from Saudi Arabia, which is the 2nd largest Arabic country in terms of area and the 6th largest Arabic country in terms of population, with 10% of its population aged <5 years. Functional constipation (FC) is an FGID that has shown a rising prevalence among Saudi infants and children in the last few years, which urges us to update our clinical practices. Nine pediatric consultants attended two advisory board meetings to discuss and address current challenges, provide solutions, and reach a Saudi national consensus for the management of pediatric constipation. The pediatric consultants agreed that pediatricians should pay attention to any alarming signs (red flags) found during history taking or physical examinations. They also agreed that the Rome IV criteria are the gold standard for the diagnosis of pediatric FC. Different therapeutic options are available for pediatric patients with FC. Dietary treatment is recommended for infants with constipation for up to six months of age. When non-pharmacological interventions fail to improve FC symptoms, pharmacological treatment with laxatives is indicated. First, the treatment is aimed at disimpaction to remove fecal masses. This is achieved by administering a high dose of oral polyethylene glycol (PEG) or lactulose for a few days. Subsequently, maintenance therapy with PEG should be initiated to prevent the re-accumulation of feces. In addition to PEG, several other options may be used, such as Mg-rich formulas or stimulant laxatives. However, rectal enemas and suppositories are usually reserved for cases that require acute pain relief. In contrast, infant formulas that contain prebiotics or probiotics have not been shown to be effective in infant constipation, while the use of partially hydrolyzed formula is inconclusive. These clinical practice recommendations are intended to be adopted by pediatricians and primary care physicians across Saudi Arabia.

Purpose: This article provides an update and overview of a nursing research program focused on understanding the pathophysiology and management of irritable bowel syndrome (IBS). Methods: This review includes English language papers from the United States, Europe, and Asia (e.g., South Korea) from 1999 to 2013. We addressed IBS as a health problem, emerging etiologies, diagnostic and treatment approaches and the importance of a biopsychosocial model. Results: IBS is a chronic, functional gastrointestinal disorder characterized by recurrent episodes of abdominal pain and alterations in bowel habit (diarrhea, constipation, mixed). It is a condition for which adults, particularly women ages 20-45, seek health care services in both the United States and South Korea. Clinically, nurses play key roles in symptom prevention and management including designing and implementing approaches to enhance the patients' self-management strategies. Multiple mechanisms are believed to participate in the development and maintenance of IBS symptoms including autonomic nervous system dysregulation, intestinal inflammation, intestinal dysbiosis, dietary intolerances, alterations in emotion regulation, heightened visceral pain sensitivity, hypothalamic-pituitary-adrenal dysregulation, and dysmotility. Because IBS tends to occur in families, genetic factors may also contribute to the pathophysiology. Patients with IBS often report a number of co-morbid disorders and/or symptoms including poor sleep. Conclusion: The key to planning effective management strategies is to understand the heterogeneity of this disorder. Interventions for IBS include non-pharmacological strategies such as cognitive behavior therapy, relaxation strategies, and exclusion diets.
