A household survey was conducted to compare the patterns of morbidity and medical care utilization between medical aid beneficiaries and medical insurance beneficiaries. The study population included 285 medical aid beneficiaries that were completely surveyed and 386 medical insurance benficiaries selected by simple random sampling from a Dong(Township) in Taegu. Well-trained surveyers mainly interviewed housewives with a structured questionnaire. The morbidity rates of acute illness during the 15-day period, were 63 per 1,000 medical aid beneficiaries and 62 per 1,000 medical insurance beneficiaries. The rates for chronic illness were 123 per 1,000 medical aid beneficiaries and 73 per 1,000 medical insurance beneficiaries. The most common type of acute illness in medical aid and medical insurance beneficiaries was respiratory disease. In medical aid beneficiaries, musculoskeletal disease was most common, but in medical insurance beneficiaries, gastrointestinal disease was most common. The mean duration of acute illness of medical aid beneficiaries was 3.8 days and that of medical insurance beneficiaries was 6.8 days. During the one year period, mean duration of medical aid beneficiaries chronic illnesses was 11.5 months which was almost twice as long compared to medical insurance beneficiaries. Pharmacy was most preferrable facility among the acute illness patient in medical aid beneficiaries, but acute cases of medical insurance beneficiaries visited the clinic most commonly. Chronic cases of both groups visited the clinic most frequently. There were some findings suggesting that much unmet need existed among the medical aid beneficiaries. In acute cases, the average number of days of medical aid users utilized medical facilities was less than medical insurance users. On the other hand, the length of medical care utilization of chronic cases was reversed. Geographical accessibility was the most important factors in utilization of medical facilities. Almost half of the study population answered the questions about source of funds on medical security correctly. Most respondents considered that the objective of medical security was afford ability. The chief complaint on hospital utilization was the complicated administrative procedures. These findings suggest that there were some problems in the medical aid system, especially in the referral system.
Inflammatory bowel disease is an immune disorder associated with chronic mucosal inflammation and severe ulceration in the gastrointestinal tract. Antibodies against proinflammatory cytokines, including TNF${\alpha}$, are currently used as promising therapeutic agents against the disease. Stabilization of the transcript is a crucial post-transcriptional process in the expression of proinflammatory cytokines. In the present study, we assessed the expression and histological distribution of the HuR protein, an important transcript stabilizer, in tissues from experimental animals and patients with Crohn's disease. The total and cytosolic levels of the HuR protein were enhanced in the intestinal epithelia from dextran sodium sulfate (DSS)-treated mice compared to those in control tissues from normal mice. Moreover, the expression of HuR was very high only in the mucosal and glandular epithelium, and the relative localization of the protein was sequestered in the lower parts of the villus during the DSS insult. The expression of HuR was significantly higher in mucosal lesions than in normal-looking areas. Consistent with the data from the animal model, the expression of HuR was confined to the mucosal and glandular epithelium. These results suggest that HuR may contribute to the post-transcriptional regulation of proinflammatory genes during early mucosal insults. More mechanistic investigations are warranted to determine the potential use of HuR as a predictive biomarker or a promising target against IBD.

Background: Helicobacter pylori (H.pylori) is associated with chronic gastritis, peptic ulcers, gastric adenocarcinomas and mucosa associated tissue lymphomas. Cytotoxin associated gene A (CagA) is one of the virulence factors of H.pylori. It is hypothesized that reactive oxygen species (ROS) play roles in H.pylori associated disease especially in development of gastric adenocarcinoma. Individuals infected with H.pylori bearing CagA produce more ROS than others. 8-hydroxydeoxyguanosine (8OHdG) is an in vitro marker of DNA damage and oxidative stress. The aim of this study was to investigate the relationship between 8OHdG level, H.pylori infection and CagA and alterations of serum 8OHdG level after H.pylori eradication. Materials and Methods: Patients admitted with dyspeptic complaints and upper gastrointestinal endoscopy were assessed. H.pylori was determined from histopathology of specimens. Serum 8OHdG levels of three groups (H.pylori negative, H. pylori positive CagA negative and H.pylori positive CagA positive) were compared. Patients with H.pylori infection received eradication therapy. Serum 8OHdG levels pretreatment and posttreatment were also compared. Results: In total, 129 patients (M/F, 57/72) were enrolled in the study. Serum 8OHdG level of H.pylori negative, H. pylori positive CagA negative and H.pylori positive CagA positive groups were significantly different ($5.77{\pm}1.35ng/ml$, $5.43{\pm}1.14ng/ml$ and $7.57{\pm}1.25ng/ml$ respectively, p=0.05). Furthermore, eradication therapy reduced serum 8OHdG level ($6.10{\pm}1.54ng/ml$ vs $5.55{\pm}1.23ng/ml$, p=0.05). Conclusions: Individuals infected with H.pylori bearing CagA strains have the highest serum 8OHdG level and eradication therapy decreases the serum 8OHdG level. To the best of our knowledge this is the first study that evaluated the effect of CagA virulence factor on serum 8OHdG level and the effect of eradication therapy on serum 8OHdG levels together. Eradication of CagA bearing H.pylori may prevent gastric adenocarcinoma by decreasing ROS. 8OHdG level may thus be a good marker for prevention from gastric adenocarcinoma.
A 12-year-old castrated male Shih-tzu dog presented with vomiting, anorexia, and weight loss. The patient's medical history and hematological, radiographic, ultrasonographic, and endoscopic findings were used for diagnosis. The patient's medical history showed that he was being treated for chronic kidney disease since a few weeks. The serum biochemical analysis showed moderate azotemia. However, abdominal radiographic and ultrasonographic findings showed the presence of a mass in the pylorus area of the stomach. On gastrointestinal endoscopic examination, the proliferative mass was found in the pyloric antrum. The histopathological results of the endoscopic biopsy specimen indicated that it was strongly suspected a gastric adenoma; therefore, we surgically excised the pyloric outflow region via a Y-U pyloroplasty. The histopathological examination of the surgically excised specimen also indicated that the mass was a gastric adenoma. After surgical treatment, the patient's condition improved gradually, and the clinical symptoms diminished in approximately 3 weeks after surgery. The patient's condition was well controlled until recently, i.e., 18 months after surgery. This case report describes the clinical findings, imaging characteristics, endoscopic findings, and histopathological features of a gastric adenoma in the pyloric outflow tract of a dog.

Objectives : The purpose of this study was to assess physical illnesses, psychological difficulties, and daily life function of victims' family members one year after the Sewol ferry disaster, in order to establish a basis of strategies to promote their mental health and resilience. Methods : We statistically analyzed self-reported data collected from a survey conducted between March 22 and 28, 2015 with 139 family members of victims. Results : All respondents complained about one or more psychological difficulties, and 95.4% of them had newly diagnosed or exacerbated physical illnesses. An increased number of psychological difficulties was associated with a greater tendency to present physical illnesses including chronic headache, gastrointestinal, musculoskeletal, obstetrico-gynecological, genitourinary, and cardiovascular disease. In addition, the majority of respondents reported a decrease in life functioning. Specifically, 71.9% reported interpersonal avoidance and 63.9% reported difficulty in returning to work. Conclusions : Not only psychological trauma but also physical illness and daily functioning should be evaluated in detail and actively addressed in the bereaved family members after a catastrophe.
The purpose of the study was to assess the morbidity pattern and the medical care utilization behavior of the urban residents in the poor area. The study population included 2,591 family members of 677 households in the poor area of Daemyong 8 Dong, Nam-Gu, Taegu and 2,686 family members of 688 households, near the poor area in the same Dong, were interviewed as a control group. On this study the household interview method was applied. Well-trained interviewers visited every household in the designated area and individually interviewed heads of households or housewives for general information, morbidity condition, and medical care utilization with a structured questionnaire. Individuals were interviewed from 1 to 30 December 1988. The major results were summarized as follows : The proportion of the people below 5 years of age was 4.2% of the total study population and 5.5% were above 65 years of age in the poor area. This was slightly higher than in the control area. The average monthly income of a household in the poor area was 403,000 won versus 529,000 won in the control area. Fifty-eight percent of the residents in the poor area and sixty-one percent in the control area were medical security beneficiaries, but the proportion of medical aid beneficiaries was 7.8% in the poor area and 4.6% in the control area. The 15-day period morbidity rate of acute illnesses was 57.1 per 1,000 in the poor area and 24.2 per 1,000 in the control area. Respiratory disease is the most common acute illness in both areas. The most frequently utilized medical facility was the pharmacy among the patients with acute illnesses in the poor area. Among them 58.1% visited pharmacy initially while 38.4% of the patients in the control area visited a clinic. Among persons with illnesses during the 15 days 8.8% in the poor area and 4.6% in the control area did not seek any medical facility. Mean duration of utilization of medical facilities was 3.5 days in the poor area and 3.3 days in the control area. Initially of the medical facilities in Daemyong 8 Dong, The pharmacy in the poor area and the clinic in the control area were most commonly utilized. The most common reason for visiting the hospital was 'regular customers' in the poor area and 'geographical accessibility' in the control area. The one year period morbidity rate of chronic illness in the poor area was 83.0 per 1,000 population and 28.0 per 1,000 in the control area. Disease of nervous system was the most common chronic illness in the poor area while cardiovascular disease in male and gastrointestinal disease in female were most prevalent in the control area. The most frequently utilized medical facility was the pharmacy among the patients with chronic illnesses in the poor area. Among them 24.2% visited the pharmacy initially while 34.7% of the patients in the control area visited the out-patient department of the hospital within a 15-day period. Among the patients with chronic illnesses 34.9% in the poor area and 16.0% in the control area did not seek any medical facility. Mean duration of utilization of medical facilities was 9.2 days in the poor area and 9.9 days in the control area within a 15-day period. Initially of the medical facilities in Daemyong 8 Dong, the pharmacy in the poor area and the hospital in the control area were most commonly utilized. The most common reason for visiting the hospital, clinic, health center or pharmacy in the poor area was 'geographical accessibility' while the reason for visiting herb clinic was 'good result' and 'reputation' in both areas.
Purpose : Helicobacter pylori infection is one of the most common gastrointestinal infections worldwide; it almost invariably causes chronic gastritis. Pediatric studies may provide important insights into the mucosal immune response of H. pylori-infection, as children are not submitted to environmental factors such as alcohol, tobacco and anti-inflammatory medication. The aim of the present study was to investigate the mucosal immune response against H. pylori in clinically well-defined groups: H. pylori-positive (divided into peptic ulcer disease and gastritis) and H. pylori-negative control. Methods : Antral biopsies were obtained from 45 children undergoing an upper GI endoscopy for dyspeptic symptoms. T cells (CD3+, CD4+, CD8+) and B cells (CD20+) were analyzed by quantitative immunohistochemistry. The correlation of lymphocyte subsets of gastric mucosa with histology was evaluated. Results : T cells (CD3+, CD4+, CD8+) and B cells (CD20+) were significantly increased in the lamina propria of H. pylori-positive group (P<0.01). CD8+ T cells were significantly increased in the lamina propria of the H. pylori-positive peptic ulcer disease (P<0.01). Within the epithelium, only CD4+ T cells were significantly increased in the H. pylori-positive group (P<0.01). Gastric histological parameters had a closer correlation with lymphocytes in the lamina propria than intraepithelial lymphocytes. Conclusion : This study suggests that both T cells and B cells in the lamina propria play important roles in the local immune response of H. pylori-infected children. Furthermore, it remains to be elucidated whether CD8+ T cells in the lamina propria may contribute to peptic ulcer formation in H. pylori-infected children.
This study was carried out to analyze the food intake and associated factors of the urban poor elderly by comparing poor district, Unbong rental apartment in Bansong 2 dong with other areas in Pusan. 135 elderlies(men 36, women 99) in Unbong rental apartment, 136 elderlies(men 45, women 91) in the other areas were investigated during the period of March to August in 1994. The assumption that the study area represented poor district was satisfied because the age and sex distribution was not significantly different, and the income of the study area was significantly lower than that of the control area. The variables of hospitalized in previous 12 month, gastrointestinal problem, alcohol drinking, cigarette smoking did not differ significantly. But the variables of chronic disease, take medicine, perceived health, vitamin supplement differed significantly between two groups. Therefore some factors associated with health state in the study area are worse than those of the control area. At most of all variables, nutrients intake of the study area did not reach the recommended dietary allowances(RDA) for Koreans, and that nutrient intakes of the study area were significantly lower than those of the control area. The hypothesis of this study that nutrient status depends on economical status was proved. As for the score of nutritional knowledge, the study area was significantly lower than the control area. But as for the score of nutritional behavior, two areas were not significantly different. The latter is counter result of our hypothesis, owing to the effect of the confounding factors including education etc. As for the correlation of variables, not only economic status and educational level, but the score of nutritional knowledge effects strongly on nutrient status in the study area, the poor district. Therefore, adequate nutritional education to the elderly in e poor district should be considered.
