OBJECTIVETo determine the prevalence of functional gastrointestinal disorders in children in Shanghai.

METHODThis study was conducted on the infants and young children who were below 24 months of age recruited consecutively from April 2008 to June 2008 from the 12 communities in Minhang district in Shanghai. The questionnaire on gastrointestinal symptoms and growth was sent to 5030 children < 24 months old. The age distribution of the 5030 children was: < 6 months: 1922 infants (38.2%), 6 - < 12 months: 1933 (38.4%) infants; 12 - < 18 months: 811 (16.1%) children; 18 - < 24 months: 364 (7.2%) children.

RESULTAmong the 5030 children, 1909 had gastrointestinal disorders (38.0%). There was no significant difference in the rate of the disorders between sexes (P = 0.06). Regurgitation was found in 899 (17.9%) infants/children, constipation in 690 (13.7%), 619 (12.3%) infants/children suffered from diarrhea and only 71 (1.4%) suffered from colic. The incidence of gastrointestinal disorders was significantly different among different age groups. The incidence of constipation and regurgitation decreased and the incidence of diarrhea increased with growth (P < 0.01). Infants growth parameters in the group with gastrointestinal disorders especially in those with regurgitation were lower than those without gastrointestinal disorders, the difference is statistically significant. The hospital visit rate of infants with diarrhea was 62.68%, which was higher than the rate of the other three symptoms (4.45% - 16.90%).

CONCLUSIONGastrointestinal disorders are common in infants and young children in Shanghai and may have a great impact on growth. Early management could relieve the disorders and ensure infants to get normal growth and development.

OBJECTIVETo explore prodromes of chemotherapy-induced vomiting (CIV) and their association with CIV in lung cancer patients.

METHODSThe prodromes of CIV in 250 lung cancer patients were analyzed. Logistic regression was used to determine the symptoms most likely correlated with CIV. One hundred fifty-seven patients received medical interventions. The development of correlative symptoms and occurrence of CIV between the intervention and non-intervention groups was analyzed.

RESULTSAmong the 250 patients with the prodromes of CIV, the incidence rate of CIV was 67.2%. Logistic regression indicated that nausea, constipation, insomnia, hiccups, anorexia, and history of drinking were correlated with CIV (P < 0.05 for all). Among the 20 symptoms observed in this study, the incidence rates of relatively common symptoms were nausea (72.0%), anorexia (68.4%), taste changes (48.8%), constipation (45.6%), abdominal distension (45.6%), stomach distension(40.4%), and insomnia (40.0%). The incidence rats of all symptoms except hiccups before and after intervention had significant difference (P < 0.05 for all). The incidence rates of CIV were 30.0% in the intervention group and 50.6% in the non-intervention group, with a significant difference between the two groups (P = 0.009).

CONCLUSIONSProdromes of CIV are closely related to the occurrence of CIV. Timely intervention for prodromes of CIV can reduce the incidence rate of CIV during chemotherapy in lung cancer patients.

Human astrovirus (HAstV) is a major cause of acute diarrhea among children, resulting in outbreaks of diarrhea and occasionally hospitalization. Improved surveillance and application of sensitive molecular diagnostics have further defined the impact of HAstV infections in children. These studies have shown that HAstV infections are clinically milder (diarrhea, vomiting, fever) than infections with other enteric agents. Among the 8 serotypes of HAstV identified, serotype 1 is the predominant strain worldwide. In addition to serotype 1, the detection rate of HAstV types 2 to 8 has increased by using newly developed assays. HAstV is less common compared with other major gastroenteritis viruses, including norovirus and rotavirus; however, it is a potentially important viral etiological agent with a significant role in acute gastroenteritis. A better understanding of the molecular epidemiology and characteristics of HAstV strains may be valuable to develop specific prevention strategies.

BACKGROUND/AIMS: Gastrointestinal (GI) symptoms are common among patients with non-insulin dependent diabetes mellitus (NIDDM). Our aim was to investigate the frequency of chronic GI symptoms in Korean patients with NIDDM. METHODS: A cross-sectional survey, using a reliable and valid questionnaire, was performed in diabetes clinics from seven hospitals of the Catholic University of Korea. RESULTS: A total of 608 patients (249 males and 359 females, mean age 53.7+/-10.9 years) were investigated. The frequencies of weekly heartburn and acid regurgitation (esophageal symptoms) were 7.1% (95% confidence interval [CI], 5.0 to 9.2) and 4.4% (95% CI, 2.8 to 6.1), respectively. The frequency of dyspepsia was 13.2% (95% CI, 10.5 to 15.8). The frequencies of constipation and diarrhea were 15.0% (95% CI, 12.2 to 18.0) and 5.3% (95% CI, 3.5 to 7.1), respectively. Nausea and the use of manual maneuvers to facilitate defecation were more prevalent in women than in men. Constipation and fecal incontinence were more common in diabetes patients with long duration (>10 years). Fecal incontinence and using laxatives were more frequent in the complicated diabetes group. Using laxatives was more frequent in the uncontrolled diabetes group. CONCLUSIONS: Two-thirds of diabetic patients experienced GI symptoms. The prevalence of GI symptoms was more common in patients who had diabetic complications and a long duration of diabetes.

OBJECTIVES: This study was carried out to investigate the sources of infection and modes of transmission of an outbreak of shigellosis that occurred among students of B middle and high school in Bonghwa, Korea from May 1 to 21, 1999. METHODS: We conducted questionnaires to 468 students, 38 staffs and 9 food handlers twice times (May 6, May 21) for follow up and secondary attack rate. Personal details and history of illness and exposure to particular foods were sought. And we conducted rectal swab for culture to 243 students, 33 staffs and 9 food handlers. Bacteriological examinations of water in the school were done. Cases were identified as subjects who had diarrhea (two or more loose stools in a 24-hour periods) on or after May 1. RESULTS: A total of 307 cases (attack rate: 59.6%) of 515 subjects were identified, including 50 confirmed (46 students and 4 staffs) by S. sonnei. All 9 food handlers denied illness and were had rectal swab for culture at May 6 that were negative for S. sonnei. 146 of 307 reported fever, 156 had tenesmus, 44 reported vomiting, and only 5 of 307 reported blood in the stool. The median duration of diarrhea was 4 days (range: 1-18 days). The mean incubation period until onset of diarrhea was 63 hours (range: 16-144 hours) and the secondary attack rate was 2.8% (43 cases of 1,561 family members). Risk for illness was higher among students who had eaten watered kimchi at March 30 than among those who did not [301(72.7%) of 417 versus 5(9.6%) of 52; RR=7.51; 95% CI=3.26-17.31]. CONCLUSION: The source of infection was estimated to be contaminated watered kimchi by one or two food handler who is presumed to be carrier.

OBJECTIVETo investigate the epidemiological and clinical characteristics of norovirus infection on diarrhea patients from the enteric clinics in Beijing.

METHODSFrom April 2013 to March 2014, 1 892 fecal specimens and related epidemiological information were collected among diarrhea patients visiting the enteric clinics in Beijing. Norovirus was detected by real time RT-PCR, and data was analyzed under the descriptive epidemiological method.

RESULTSA total of 269 positive cases were found among 1 892 diarrhea patients, with a positive rate as 14.2%. Norovirus caused diarrhea mainly occurred in seasons with lower temperature. Higher positive rates of norovirus were found in northwest mountainous area. Norovirus diarrhea was more commonly seen in children between 6 month and 5 years old, with differences between the two groups statistically significant (P = 0.006). Compared with other occupation, a higher infection rate was identified in children, with differences between the two groups statistically significant (P = 0.025). Nausea and vomiting appeared more common in diarrhea patients with norovirus infection, with differences between the two groups statistically significant (P < 0.05).

CONCLUSIONNorovirus was an important pathogen which causing diarrhea in patients visiting the enteric clinics in Beijing. The virus was seen more in patients aged between 6 months and 5 years old. Nausea and vomiting were the common symptoms seen in patients with norovirus diarrhea.

Objective: To understand the epidemiologic characteristics of outbreaks, caused by norovirus-GⅡ.2、GⅡ.17 and GⅡ.4/Sydney in Guangdong Province from 2013 to 2017 and to provide scientific evidence for epidemic prevention and control. Methods: Incidence data of norovirus outbreaks in Guangdong from January 1(st) 2013 to November 30(th) 2017 were collected from Public Health Emergency Management Information System. RT-PCR was performed for every case of each outbreak to detect norovirus nucleic acid and gene sequencing was conducted to identify the genotype of norovirus. Characteristics of norovirus GⅡ.2, GⅡ.17 and GⅡ.4/Sydney outbreaks were analyzed. Directly standardized method was used to calculate the proportion of symtoms as diarrhea and vomitting. Results: From January 1(st) 2013 to November 30(th) 2017, a total of 167 norovirus outbreaks were reported in Guangdong, and 115 outbreaks were caused by norovirus GⅡ.2, GⅡ.17 and GⅡ.4/Sydney respectively. The outbreaks caused by norovirus GⅡ.2 accounted for 39.68% (25/63) in primary schools, 28.57% (18/63) in child care settings, 25.40% (16/63) in middle schools and 6.35% (4/63) in universities. Outbreaks caused by norovirus GⅡ.17 accounted for 41.03% (16/39) in middle schools, 20.51% (8/39) at workplaces, 15.38% (6/39) in primary schools, 12.82% (5/39) in universities, 5.13% (2/39) in communities and child care settings respectively. The outbreaks caused by norovirus GⅡ.4/Sydney accounted for 53.85% (7/13) in universities, 15.38% (2/13) in child care settings and at workplaces respectively, 7.69%(1/13) in primary schools and middle schools respectively. The outbreaks caused by norovirus GⅡ.2 had 77.78% (49/63) of contact transmission, 17.46% (11/63) of food-borne transmission. The outbreaks caused by norovirus GⅡ.17 showed 53.85% (21/39) of food-borne transmission, 15.38% (6/39) of contract transmission, 12.82% (5/39) of water-borne transmission. The outbreaks caused by norovirus GⅡ.4/Sydney had 53.85% (7/13) of food-borne transmission, 38.46% (5/13) of the contact transmission. In terms of the clinical manifestations, the standardized proportion of vomit was 73.76% and the proportion of diarrhea was 42.85% in cases infected with norovirus GⅡ.2, the proportion of standardized of vomit was 76.37% and the proportion of diarrhea was 51.40% in cases infected with norovirus GⅡ.17, with the standardized proportion of vomit was 54.10% and the proportion of diarrhea was 55.95% in cases infected with norovirus GⅡ.4/Sydney. Conclusions: The outbreaks caused by norovirus GⅡ.2 through contact transmission mainly occurred in primary schools, child care settings and middle schools. The outbreaks caused by norovirus GⅡ.17 through food-borne transmission mainly occurred in middle schools and at workplaces. The outbreaks caused by norovirus GⅡ.4/Sydney food-borne transmission and contact mainly occurred in universities.

BACKGROUND/AIMS: Migraine is frequently accompanied by symptoms consistent with functional gastrointestinal disorders (FGIDs). This study evaluated the prevalence of functional gastrointestinal symptoms and assessed the symptoms' relationship with the concomitant functional symptoms of anxiety, depression, and headache-related disability. METHODS: This prospective study included 109 patients with migraine who were recruited from a headache clinic at a teaching hospital. The participants completed a self-administered survey that collected information on headache characteristics, functional gastrointestinal symptoms (using Rome III criteria to classify FGID), anxiety, depression, and headache-related disability. RESULTS: In total, 71% of patients met the Rome III criteria for at least one FGID. In patients with FGID, irritable bowel syndrome was the most common symptom (40.4%), followed by nausea and vomiting syndrome (24.8%) and functional dyspepsia (23.9%). Depression and anxiety scores were significantly higher in patients meeting the criteria for any FGID. The number of the symptoms consistent with FGID in individual patients correlated positively with depression and anxiety. CONCLUSIONS: FGID symptoms defined by the Rome III criteria are highly prevalent in migraine. These symptoms correlate with psychological comorbidities, such as depression and anxiety.
