BACKGROUND: Helicobacter pylori(H. pylori) has been implicated in the pathogenesis of chronic active gastritis and peptic ulcer disease. All patients with ulcers who are infected with H. pylori receive antimicrobial therapy. Therefore diagnosis of H. pylori infection is imperative for the treatment gastritis or ulcer patients. We evaluated the four diagnostic methods and three culture media for the isolation of H. pylori. MATERIALS AND METHODS: Rapid urease test(CLO test), modified Gram stain, culture, and nested polymerase chain reaction (PCR) were performed with 108 gastroscopic biopsy specimens from patients with peptic ulcer or chronic gastritis. Among them 40 specimens were inoculated onto each of 5% sheep blood agar, e99 Yolk emulsion (EYE) agar, and 7% horse blood agar containing antibiotics. RESULTS: The positive rates were the highest by the PCR(72%), 67% by modified Gram stain, 64% by CLO test, and 57% by culture. Among the three media the horse blood agar (selective medial) gave the highest isolation rate (48%), followed by sheep blood agar (45%), and EYE agar (38%). CONCLUSION: Though PCR was the most sensitive method for the detection H. pylori modified Gram stain was sensitive enough, simple, rapid, and economical as the routine diagnostic method of H. pylori. For the culture of H. pylori combination of sheep blood agar as nonselective media and horse blood agar as selective media would show the highest isolation rate.

Protein-calorie malnutrition is common in CAPD patients and is associated with increase in morbidity and mortality in CAPD patients. There are many causes of malnutrition in CAPD patients, and it is well known that a large amount of protein losses through peritoneal membrane is one of them. To investigate the effect of the peritoneal membrane transport characteristics on the nutritional status in long-term CAPD patients, we conducted a cross- sectional study on clinically stable 115 patients (63 males and 52 females) who have been on CAPD for more than 2 years, and assessed nutritional status by subjective global assessment (SGA), biochemical, anthropometric and urea kinetic parameters. Patients were divided into 4 groups according to the results of standard peritoneal equilibration test (PET). The results were as follows: 1) The patients were divided into 4 groups according to the PET results: high transporter (n=16, 14%), high average transporter (n=38, 33%), low average transporter (n=50, 43%), and low transporter (n=11, 10%). 2) The mean age of the patients was 50.1+/-11.6 years (range, 19-75) with sex ratio (M:F) 1.2:1 and mean duration of dialysis was 57.5+/-27.8 months (range, 24-135). The mean body weight (Bwt) was 59.2+/-8.9kg, percent ideal body weight (%IBW) was 104.7+/-15.6%, %lean body mass (LBM)/Bwt was 82.1+/-11.1%, and malnourished patients by subjective global assessment (SGA) were 32.2% (38/115). 3) The mean BUN, creatinine, total protein, and albumin level of the patients were 54.5+/-13.1mg/dL, 12.3+/-3.0mg/dL, 6.7+/-0.8g/dL, and 3.8+/-0.6g/dL, respectively. 4) There were no significant differences in age, sex ratio, CAPD duration, peritonitis rate, %LBM/ Bwt, and SGA among the 4 groups. 5) Total protein (g/dL) and albumin (g/dL) levels in high transporters were 6.4+/-0.5, 3.5+/-0.4, respectively, and they were significantly lower than those of low transporters (7.2+/-0.6, 4.2+/-0.5) (P<0.05). 6) 24 hour dialysate protein (g/day) and albumin (g/day) losses were significantly higher in high transporters (8.10+/-1.85, 4.19+/-1.23) compared to those of low transporters (5.07+/-1.85, 2.78+/-0.99) (P<0.05). 7) The level of IGF-1 (ng/mL) was significantly lower in high transporters (150.5+/-86.2) compared to that of low transporters (310.3+/-162.1) (P<0.05). 8) The level of BUN (mg/dL), Cr (mg/dL) were also lower in high transporters (45.4+/-13.1, 10.1+/-2.0) than those of low transporters (61.6+/-18, 14.7+/-2.7), but there were no significant differences in Hct, total cholesterol, prealbumin, and transferrin among the 4 groups. 9) There were no statistically significant differences in Kt/Vurea, RRF, NPCR, dietary calorie and protein intakes among the 4 groups. 10) Anthrometric parameters such as TSF, BSF, MAC and LBM measured by three different methods (LBMCr, LBMimp, LBManthro) didn't show any significant differences among the 4 groups. In conclusion, increased peritoneal permeability may not adversely affect SGA and anthropometric status of long-term CAPD patients, although it is associated with lower serum albumin, creatinine, and IGF-1 level. Clinical significance of these findings remains to be elucidated.

OBJECTIVE: The purpose of the current study was to evaluate survival outcome according to the expression status of CD73 in patients with epithelial ovarian cancer. METHODS: A total of 167 patients with epithelial ovarian cancer were enrolled in the current study. For each patient, a retrospective review of medical records was conducted. Immunohistochemical staining for CD73, CD8, FoxP3, and CD68 was performed using tissue microarray made with paraffin embedded tissue block. RESULTS: Among the enrolled patients, 29.9% of patients (n=50) showed negative expression for CD73, whereas 70.1% of patients (n=117) showed positive expression for CD73. The CD73 positive group showed better prognosis compared to the CD73 negative group (5-year overall survival of CD73 positive group, 73.0%; that of CD73 negative group, 50.1%; p=0.023). CD73 was more frequently expressed in mucinous adenocarcinoma and clear cell carcinoma compared to serous or endometrioid adenocarcinoma. In addition, CD73 overexpressions were more frequently detected in patients with known good prognostic factors, i.e., low stage, well/moderate differentiation, negative peritoneal cytology, no lymphovascular involvement, and no macroscopic residual tumor after debulking surgery. There was significantly more infiltration of regulatory T cells in the CD73 negative group compared to the CD73 positive group. CONCLUSION: Good prognosis in patients with overexpression of CD73 may be due to that overexpression of CD73 was more frequently observed in epithelial ovarian cancer patients with known good prognostic factors. Therefore, this result means that favorable differentiation and stage have more influence on survival outcome than adverse effect of CD73 per se.

PURPOSE: The aim of this study was to identify the clinical features and natural history of dietary protein induced proctocolitis (DPIPC) and to detect the causative foods of DPIPC, and to evaluate the effect of elimination of the foods on the course of the disease. METHODS: Between March 2003 and July 2004, data from 30 consecutive patients with DPIPC who were followed for over 6 months, was reviewed. The diagnostic criterion used for DPIPC was an increase in the number of eosinophils in the lamina propria (> or =60 per 10 high-power fields). In breast feeding mothers, 5 highly allergenic foods were eliminated from the maternal diet for 7 days, namely, allergenic food groups such as dairy products, eggs, nuts and soybean, fish and shellfish, and wheat and buckwheat. We observed the disappearance or appearance of hematochezia after elimination or challenge with the offending foods. RESULTS: Before diagnosis infants were breast-fed (93.3%) or formula-fed (6.7%). Mean age at symptom onset was 11.5+/-5.1 (5~24) weeks, and mean age at diagnosis was 17.8+/-9.5 (8~56) weeks. Duration from symptom onset to diagnosis was 6.3+/-6.7 (0~36) weeks. Mean peripheral blood eosinophil count was 478+/-320 (40~1,790)/mm3 and eosinophilia (>250/mm3) was observedin 90.0% of patients. None of patients were found to have an increased serum IgE level. Of 15 patients that received sigmoidoscopy, nodular hyperplasia with erosion was observed in 93.3%. Of 27 patients whose mother ate the diet eliminated the 5 food groups, hematochezia diappeared in 74.1% of patients. Offending foods were identified as dairy products (37.5%), wheat and buckwheat (27.5%), fish and shellfish (20.0%), nuts and soybean (7.5%) and eggs (7.5%). A free maternal diet without patient's clinical symptoms was achieved at 29.4+/-8.7 (9~44) weeks of patient's age, and a free baby diet without blood in stools was achieved at 37.5+/-9.7 (12~56) weeks of age. CONCLUSION: DPIPC commonly occurs in exclusively breast-fed babies. Elimination of the above-mentioned 5 hyper-allergenic food groups from the maternal diet for 7days enables the detection of the offending foods. DPIPC is a transient disorder and 96.0% of patients can tolerate the offending foods at 12 months of age.

PURPOSE: Though caustic injury of the upper digestive tract can lead to severe sequelae, there are few clinical studies on this subject. This study was undertaken to evaluate the clinical characteristics, the endoscopic findings and the risk factors of the upper digestive lesions in patient with caustic ingestion injury. METHODS: We retrospectively reviewed the medical records of 137 patients who ingested caustic materials and who visited to our emergency room from January, 2000 to June, 2009. RESULTS: The most common ingested agent was sodium hypochlorite (44.5%), followed by acetic acid (19.7%), hydrochloric acid (11.7%) and lye (8.0%). Ingestion for suicidal attempt (62.0%) was more frequent than accidental ingestion (30.7%). Grade IIa injury was the most frequent finding on endoscopy of the esophagus and Grade I injury was the most frequent finding on endoscopy of the stomach. For the late sequelae, there were 9 cases (6.6%) of esophageal stricture and 2 cases (1.5%) of gastric outlet obstruction. The initial signs and symptoms did not correlate with the development of stricture, but leukocytosis, and grade III injury were related to the risk of developing stricture. CONCLUSION: Caustic injury of the upper gastrointestinal tract is frequently observed on early endoscopy and it can cause significant late sequelae such as stricture. Therefore, it is necessary to evaluate these patients with regular follow up endoscopic examinations for the management of late sequelae.

Diverticular disease of the colon is frequently involved in Western countries, which in korea, it is regarding as rare disease. In Western the diverticulosis is mainly affected on left side and increasing in according to age and false type is more frequent than ture type. While in oriental countries, the diverticulosis of the colon is mainly affected on right side and it is more frequent in younger patients. Cecal diverticulitis is known to a very rare disease and very difficult to be differenciated from acute scopy has purnished another useful tool in the differential diagnosis of diverticular disease. We experienced a case of cecal diverticultitis which had been diagnosed by colonofiberscopy and reviewed literatures briefly.

PURPOSE: A new classification of gastrointestinal food allergy was published, but the changes of terminology between previously reported terms and the new ones were in a state of disorder. This has resulted in confusion between medical communication and diagnostic and therapeutic approaches. The clinical observations of infants presenting with gastrointestinal cow milk allergy (GI-CMA) were performed, and the changes in the terminology reviewed through the published Korean literature. METHODS: Between March 2003 and July 2003, data from 37 consecutive infants with GI-CMA, aged 2 weeks to 15 months, were reviewed. The challenge and elimination test of cow milk, and the endoscopic and histologic findings, were used for the seven subdivisions of GI-CMA according to a new classification on the basis of patients' ages, clinical manifestations and location of gastrointestinal lesions. RESULTS: The 37 patients had a mean age of 5.4+/-4.8 months, with those observed in 26 (70.3%) of patients being below 6 months of age. The seven final diagnoses were; cow milk protein-induced enterocolitis (CMPIE) in 12 (32.4%), cow milk protein proctitis (PROC) in 12 (32.4%), IgE-mediated (IGE) in 6 (16.2%), gastroesophageal reflux-associated cow milk allergy (GERA) in 5 (13.5%) and eosinophilic gastroenterocolitis in 2 (5.4%). CMPIE was revealed as the typical type in 7 (18.9%) and the atypical type in 5 (13.5%), and all of typical CMPIE revealed cow milk protein-induced enteropathy. The mean age at symptom onset was 4.3+/-0.8 months, and for those with typical and atypical CMPIE, and PROC and GERA were 3.8+/-4.6, 10.4+/-3.8, 3.4+/-3.9 and 7.8+/-5.7 months, respectively (p<0.05). The period from onset of symptom to diagnosis was 2.4+/-3.3 (0.5~12) months, with those observed in atypical CMPIE and GERA being over 3months. Although the birth weights in all patients were within the 10~90 percentile range, the body weights on diagnoses were below the 3 percentile in 48.6%; IGE 16.7%, EOS 0%, typical CMPIE 85.7%, atypical CMPIE 60.0%, PROC 25.0% and GERA 100% (p<0.05). Through the review of the Korean literature, 8 case reports and 14 original articles for GI-CMA were found. CONCLUSION: GI-CMA is not a rare clinical disorder and is subdivided into seven categories on the basis of the patient's age, clinical manifestations and location of the gastrointestinal lesions. The terms for GI-CMA are changing with new classifications, and careful approaches are necessary for medical communications.
