Purpose: This study identified sociodemographic characteristics, health status, health care utilization and related factors of Asian immigrant women in Korea. Methods: Data were collected from 465 immigrant women from China, Vietnam, the Philippines, and other Asian countries using standardized questionnaires. Descriptive statistics and $X^2$-test were performed utilizing SPSS version 17. A p-value <.05 was considered statistically significant. Results: Subjects had relatively good subjective health. The most prevalent conditions were, in order, anemia, gastrointestinal diseases, gynecological diseases, and depression. Subjects utilized mostly hospitals or clinics when sick. There were significant relationships between health care utilization and factors including residence, time since immigration and economic status. The rate of non-treatment in hospitals or clinics was 30.1% during the previous year, with significant relationships between non-treatment and factors including time since immigration and economic status. The major reasons for non-treatment were the burden of hospital expenses followed by communication difficulty. Conclusion: Public health efforts should be targeted to Asian immigrant women to improve their health status and support health care utilization.

Escherichia coli are the predominant facultative bacteria found in the gastrointestinal tract of animals and humans. Some strains of E. coli that acquire virulence factors and cause foodborne and waterborne diseases in humans are called pathogenic E. coli and can be divided into five pathotypes according to the virulence mechanism: EAEC, EHEC, EIEC, EPEC, and ETEC. Although selective media have been developed to detect E. coli, distinguishing pathogenic strains from non-pathogenic ones is difficult because of their similar biochemical properties. Therefore, it is very important to find a new and effective diagnostic method to identify pathogenic E. coli. With recent advances in molecular biology and whole genome sequencing, the use of polymerase chain reaction (PCR) is increasing rapidly. In this review paper, we provide an overview of pathogenic E. coli and present a review on PCR detection methods that can be used to diagnose pathogenic E. coli. In addition, the possibility of real-time PCR incorporating IAC is introduced. Consequently, this review paper will contribute to solving the current challenges related to the detection of pathogenic E. coli.

The prognosis for pancreatic cancer patient is very poor. Patients with locally advanced disease have a median survival time of 8 to 12 months, and patients with distant metastases have significantly worse outcomes, with a median survival time of only 3 to 6 months. Approximately 30% of patients with pancreatic cancer present with locally advanced disease defined as unresectable pancreatic cancer without evidence of distant metastatic disease. Primary treatment options in locally advanced pancreatic cancer include chemotherapy and radiotherapy. Here, we reported a patient with locally advanced pancreatic cancer who does not want further chemotherapy because of chemotherapy induced nausea and vomiting. Irreversible electroporation was performed. Irreversible electroporation was well tolerated in this case, and may be a therapeutic modality for selected patients with locally advanced pancreatic cancer.

Background: Colorectal cancer (CRC) is the most common gastrointestinal malignancy and is a significant cause of mortality. Its incidence is generally increasing in Asia. Reports from the West have indicated that the incidence of rectal cancer is increasing in the younger population. This study assessed the time trend of CRC in Brunei Darussalam specifically assessing the different age groups at which the incidences start to increase. Materials and Methods: The National Cancer registry was reviewed (1991 to 2014). The age standardized rate (ASR) and the age specific incidence rates (ASIRs) for three time periods (1991-1998), (1999-2006) and (2007-2014) were calculated. Results: The mean age of diagnosis was $59.3{\pm}14.6$ years old, incidences being slightly higher amongst men (57.6%) and Malays (67.1%). The most common tumor type was adenocarcinoma (96.4%). Rectal cancers accounted for 35.2% (n=372/1,056) of all cancers of the large bowel; more men were affected than women. The proportion of rectal cancer was also high among the indigenous group. In the three time periods, the ASR for CRC increased from 16 per 100,000 (1991-1998) to 19.6 per 100,000 (1999-2006) and 24.3 per 100,000 (2007-2014). The ASIRs for CRC increased markedly between the time periods 1998-2006 and 2007-2014, beginning in the 40-44 years age group. For rectal cancers, the ASIRs started to increase in the 25-29 age group onward whereas for colon cancers, the increase was observed at a later age, starting from the 45-49 age group. Conclusions: Our study showed an increase in the incidence of CRC including in the younger age groups. The increase was seen earlier in rectal cancer compared to colon cancer. These data mirror the trends reported from the West.

Objective: This work aims to investigate the therapeutic regimen of brain metastatic cancers and the relationship between clinical features and prognosis. Methods: Clinical data of 184 patients with brain metastatic cancers were collected and analysed for the relationship between survival time and age, gender, primary diseases, quantity of brain metastatic foci, their position, extra cranial lesions, and therapeutic regimens. Results: The average age of onset was 59.1 years old. The median survival time (MST) was 15.0 months, and the patients with breast cancer as the primary disease had the longest survival time. Females had a longer survival time than males. Patients with meningeal metastasis had extremely short survival time. Those with less than 3 brain metastatic foci survived longer than patients with more than 3. The MST of patients receiving radiotherapy only and the patients receiving chemotherapy only were all 10.0 months while the MST of patients receiving combination therapy was 16.0 months. Multiple COX regression analysis demonstrated that gender, primary diseases, and quantity of brain metastatic foci were independent prognostic factors for brain metastatic cancers. Conclusions: Chemotherapy is as important as radiotherapy in the treatment of brain metastatic cancer. Combination therapy is the best treatment mode. Male gender, brain metastatic cancers originating in the gastrointestinal tract, more than 3 metastatic foci, and involvement of meninges indicate a worse prognosis.

Purpose: The aim of this study was to evaluate the correlation among descriptions regarding one's stool, Bristol stool form scale and colon transit time (CTT) in children with gastrointestinal symptoms, along with the clinical significance of Bristol stool form scale. Methods: 489 patients treated in the pediatric department of Severance hospital with gastrointestinal symptoms between May 2002 to May 2004 were included. We analyzed their age, sex, verbal descriptions of stool, Bristol stool form types, and CTT measured by Metcalf's method. Results: 116 children were under 5 years of age, 202 children between 5.1~10, and 171 children 10 years of age or older. Their mean age was $8.2{\pm}3.9years$. Stools were described as loose in 65 children (13.3%), normal in 221 (45.2%), hard in 188 (38.4%), and mixed (loose+hard) in 15 (3.1%). According to Bristol stool form scale, 57 children(11.7%) were classified as type 1, 66 (13.5%) as type 2, 203 (41.5%) as type 3, 109 (22.3%) as type 4, 36 (7.4%) as type 5, 18 (3.7%) as type 6, and 1 (0.2%) as type 7. Their mean CTT was checked $35.9{\pm}19.5hours$. Though no significant relationship was observed between age and CTT (p=0.4), a significant relationship was noted among patient's stool description, Bristol stool form scale and CTT (p<0.001). However, concordance between stool description and Bristol stool form was relatively low in the loose stool group (29%) and normal stool group (37%) while high in the hard stool group (87%). Conclusion: Bristol stool form scale could be used in the estimation of CTT in clinical practice.

Background: Esophageal cancer in Iran is the sixth most common cancer and is particularly important in east Azerbaijan. The aim of this study was to calculate survival rates and define prognostic factors in esophageal cancer patients. Methods: In this study, all patients with esophageal cancer registered in the Radiation Therapy Center, during March 2006 to March 2011, were analyzed and followed up for vital status. Data were analyzed using the Kaplan-Meier method and the Cox proportional hazard models. Results: Out of 532 patients, survival information was available for 460, including 205 (44/ 5%) females and 255 (55/4%) males. The mean age was $65.8{\pm}12.2$, ranging from 29 to 90 years at the time of diagnosis. 1-, 3- and 5-year survival rates after diagnosis were 55%, 18% and 12%, respectively, with a median survival time of $13.2{\pm}.7$ (CI 95% =11.8-14.6) months. In the univariate analysis, age (P=0/001), education (P=0/001), smoking status (P= 0/001), surgery (P= 0/001), tumor differentiation (P= 0/003) and tumor stage (P= 0/001) were significant prognostic factors. Tumor morphology, sex, place of residence, tumor histology and tumor location did not show any significant effects on the survival rate. In multivariate analysis, age (P = 0/003), smoking (P= 0/01) and tumor stage (P= 0/001) were significant independent predictors of survival. Conclusion: In summary, prognosis of esophageal cancer in North West of Iran is poor. Therefore, reduction in exposure to risk factors and early detection should be emphasized to improve survival.

Purpose: Fatigue is one of the most common complaints of cancer patients. In this study, we analyzed the change of fatigue level and general symptoms as time go by, so that, we could explain more on the mechanism and change of fatigue in relation with treatment, and explore the influencing factors. Method: The subjects of this study were 50 GI cancer patients who have visited the cancer center of A hospital in Suwon. We measured fatigue by using the Revised Piper Fatigue Scale(RPFS) at the time of starting and finishing induction chemotherapy, and starting the 2nd cycle of chemotherapy. Results: 1) The fatigue score was 2.81, 3.73, and 3.82 in a 10 point scale at the time of starting and finishing induction chemotherapy, and starting the 2nd chemotherapy, respectively. This means fatigue persisted until after the treatment. 2) Fifty two percent of participants complained of some kinds of symptoms when starting the treatment, and the proportion increased up to 92% when finishing the treatment. 3) Fatigue scores were significantly high in patients with fatigue-related symptoms than for patients without those symptoms. 4) Fatigue scores showed significant differences according to patients' general characteristics such as age, educational level, economic status, occupation, diagnosis, hematocrit, weight, and amount of sleepy. Conclusion: We have to develop intervention strategies to reduce fatigue in cancer patients in the consideration of influencing factors.

Effects of very low level of lead in diet and exposure time on the accumulation and distribution in organs and tissues was investigated with growing rats. 21 days old Sprague-Dawley rats were exposed to lead for 7, 14 and 21 days by feeding of 0.03, 0.42, 0.92 and 1.46mg/kg Pb as Pb-acetate containing diet, respectively. Lead concentrations in blood, liver, kidney and bone exhibit a linear relationship with lead levels in diet. After 7 days of exposure, the greatest dose dependent accumulation of lead was found in kidney and followed in bone. However, after 14 and 21 days, the dose dependent accumlation of lead in bone was about two fold greater than that in kidney. The accumulation of lead in liver and blood was relatively low. As continuous exposure to lead, the concentrations of lead in liver, kidney, blood and intestinal tracts were rather not increased with exposure time. However, bone lead concentration was increased with exposure time by feeding of 0.92 and 1.46mg/kg Pb in diet, but not 0.42mg/kg. The lead concentration in gastrointestinal tracts tends also to increasing with lead levels in diet after 7 and 14 days of exposure. However, by 21 days of exposure the lead concentration revealed relatively constant value regardless of the dietary lead levels. It is concluded that the binding capacity of the lead in blood, liver, kidney and bone seems to be increased with increasing lead levels in diet. The lead concentration in these organs, with the exception of the lead in bone, seems, however, to be standing under steady state regulation by continued exposure with the same dietary lead level. Therefore, by chronic exposure condition with environmental relevant lead level bone might be a principle targe organ for lead and blood lead repesents better the current lead exposure than the lead body burden.

Purpose: The clinical presentations of inflammatory bowel disease (IBD) prior to diagnosis are so diverse or vague that many of them waste time before final diagnosis. This study was undertaken to know the medical history of the pediatric patients until the final diagnosis could be reached. Methods: The medical records of all pediatric patients who were diagnosed with IBD (Crohn's disease [CD] in 14 children, ulcerative colitis [UC] in 17) during the last 13 years were reviewed. We investigated the length of the diagnostic time lag, chief clinical presentation, and any useful laboratory predictor among the routinely performed examinations. Indeterminate colitis was not included. Results: The mean ages of children at the final diagnosis was similar in both diseases. As for the pre-clinical past history of bowel symptoms in CD patients, 5 were previously healthy, 9 had had 1-3 gastrointestinal (GI) symptoms, weight loss, bloody stool, anemia and rectal prolapse. With UC, 9 were previously healthy, 8 had had 1-3 GI symptoms, bloody stool, anorexia. The average diagnostic time lag with CD was 3.36 months, and with UC 2.2 months. Body mass index (BMI) and the initial basic laboratory data (white blood cell, hemoglobin, mean corpuscular volume, serum albumin, and serum total protein) were lower in CD, statistically significant only in BMI. Conclusion: IBD shows diverse clinical symptoms before its classical features, making the patients waste time until diagnosis. It is important to concern possibility of IBD even in the mildly sick children who do not show the characteristic symptoms of IBD.
