OBJECTIVE: Persistent infection of HPV increases the chance of carcinoma in situ of cervix through stages of cervical intraepithelial neoplasia (CIN) 1, 2, and 3, and finally progresses into cervical cancer. We aimed to explore the safety and efficacy of BLS-M07 which is orally administered agent expressing human papillomavirus (HPV) 16 E7 antigen on the surface of Lactobacillus casei in patients with CIN 3. METHODS: Patients with CIN 3 were recruited in our clinical trial. Reid Colposcopic Index (RCI) grading and serum HPV16 E7 specific antibody production were used to evaluate efficacy of BLS-M07. In phase 1, BLS-M07 was administered orally, 5 times a week, on weeks 1, 2, 4, and 8 with dosages of 500 mg, 1,000 mg, and 1,500 mg. In phase 2a, patients were treated with 1,000 mg. The primary endpoints were the safety and the pathologic regression on colposcopic biopsy. RESULTS: Nineteen patients were enrolled in the CIN 3 cohort. In phase 1, no patients experienced dose limiting toxicity. No grade 3 or 4 treatment-related adverse events or deaths were observed. At 16 weeks after treatment, RCI grading was improved and serum HPV16 E7 specific antibody production increased (p<0.05). Six of 8 (75%) patients with CIN 3 were cured in phase 2a. CONCLUSIONS: Oral immunization with BLS-M07 increases production of serum HPV16 E7 specific antibody which induces protective humoral immunity. The safety of this oral vaccine was proved and could be a competitive non-surgical therapeutic agent of CIN 3. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT02195089

PURPOSE: The aims of this study were as follow: 1) to de scribe the expression status of estrogen receptor-alpha and -beta mRNAs in five gastric carcinoma cell lines; 2) to evaluate in vitro the effects of 17beta-estradiol and estrogen receptor antagonists on the proliferation of the cell lines. MATERIALS AND METHODS: Detection of estrogen receptor-alpha and estrogen receptor-beta mRNA in five human gastric cancer cell lines (AGS, KATO III, MKN28, MKN45 and MKN74) was made by the reverse transcription-polymerase chain reaction system. To evaluate the effect of 17beta-estradiol and estrogen receptor antagonists on the proliferation of gastric cancer cell line, the cell lines which expressed both es trogen receptors were chosen and treated with 17beta-estradiol and estrogen receptor antagonists (methyl-piperidino-pyrazole and pyrazolo [1,5-a] pyrimidine). Cell proliferation was assessed with the methylthiazol tetrazolium test. RESULTS: Estrogen receptor-alpha and estrogen receptor-beta mRNAs were expressed in three (KATO III, MKN28 and MKN45) and all of the five gastric cancer cell lines, respectively. At higher concentrations, 17beta-estradiol inhibited cell growth of MKN28, MKN45 and KATO III cell lines. Neither estrogen receptor-alpha nor estrogen receptor-beta antagonist blocked the anti-proliferative effect of 17beta-estradiol. CONCLUSIONS: Our results indicate that estrogen receptor-beta mRNAs are preferentially expressed in gastric cancers and also imply that hormone therapy rather than estrogen receptor blockers may be a useful strategy for the treatment of estrogen receptor-beta positive gastric cancer. Its therapeutic significance in gastric cancer are, however, limited until more evidence of the roles of estrogen receptors in the gastric cancer are accumulated.

Endoscopic retrograde cholangiopancreatography (ERCP) is an essential technique for the diagnosis and treatment of pancreatobiliary diseases. However, ERCP-related complications such as pancreatitis, cholangitis, hemorrhage, and perforation may be problematic. For a successful and safe ERCP, preprocedural evaluations of the patients and intervention-related risk factors are needed. Furthermore, in light of the recent population aging and increase in chronic cardiopulmonary diseases in Korea, precautions including endoscopic sedation and prevention of cardiopulmonary complications should be considered. In this literature review, we describe these risk factors and the use of endoscopic sedation. In addition, we reviewed the commonly available guidewires, including their materials and options, used as a basic accessory for ERCP procedures.

Iatrogenic duodenal perforation associated with endoscopic retrograde cholangiopancreatography (ERCP) is a very uncommon complication that is often lethal. Perforations during ERCP are caused by endoscopic sphincterotomy, placement of biliary or duodenal stents, guidewire-related causes, and endoscopy itself. In particular, perforation of the medial or lateral duodenal wall usually requires prompt diagnosis and surgical management. Perforation can follow various clinical courses, and management depends on the cause of the perforation. Cases resulting from sphincterotomy or guidewire-induced perforation can be managed by conservative treatment and biliary diversion. The current standard treatment for perforation of the duodenal free wall is early surgical repair. However, several reports of primary endoscopic closure techniques using endoclip, endoloop, or newly developed endoscopic devices have recently been described, even for use in direct perforation of the duodenal wall.

Endoscopic palliative biliary drainage is considered as a gold standard treatment in advanced or inoperable hilar cholangiocarcinoma. Also, metal stents are preferred over plastic stents in patients with >3 months life expectancy. However, the endoscopic intervention of advanced hilar obstruction is often more challenging and complex than that of distal malignant biliary obstructions. In this literature review, we describe the issues commonly encountered during endoscopic unilateral (single) versus bilateral (multiple) biliary stenting for malignant hilar obstruction. Also, we provide technical guidance to improve the technical success rates and patient outcomes, focusing on bilateral metallic stenting techniques such as stent-in-stent or side-by-side deployment.

BACKGROUND: The relationship of lifestyle and socioeconomic factors with weight change over 4 years in Korean middle-aged group was assessed. METHODS: A total of 1,167 men, aged 40~59 years, were selected from the Health Promotion Center of Ulsan University Hospital during the period of Jan. 2000 through Mar. 2000. Including anthropometric measures, designed questionnaires were administered concern lifestyle behavior topics with cigarette smoking, exercise, alcohol consumption, dairy product consumption and socioeconomic factors of monthly income and education. The subjects were divided into three groups by body mass index (BMI: kg/m(2)); normal (<23 kg/m(2)), overweight, and obesity (> or =25 kg/m(2)). After 4 years of follow-up, the men were classified into weight change categories; 1) stable weight group (from normal to normal, from overweight to overweight) and 2) weight gain group (from normal to overweight/obesity, from overweight to obesity). RESULTS: The weight gain group were 18.4% (n=215) and the stable overweight group were 81.6% (n=952). Adjusted for age, the frequency of dairy product consumption, the frequency of alcohol drinking, the regularity of exercise, education and monthly income, the smokers (> or =10/day) had significantly high incidence rates of increase in weight (odds ratio=1.77, 95% CI 1.07~2.90). The increased dairy consumers (> or =4/week) had significantly low incidence rates of increase in weight (odds ratio=0.43, 95% CI 0.20~0.93). Otherwise, there were no significant relationships in weight change. CONCLUSION: Smoking and decreased dairy product consumption were related to the increase in weight.

8.Optimal Use of Wire-Assisted Techniques and Precut Sphincterotomy.
Clinical Endoscopy 2016;49(5):467-474
Various endoscopic techniques have been developed to overcome the difficulties in biliary or pancreatic access during endoscopic retrograde cholangiopancreatography, according to the preference of the endoscopist or the aim of the procedures. In terms of endoscopic methods, guidewire-assisted cannulation is a commonly used and well-known initial cannulation technique, or an alternative in cases of difficult cannulation. In addition, precut sphincterotomy encompasses a range of available rescue techniques, including conventional precut, precut fistulotomy, transpancreatic septotomy, and precut after insertion of pancreatic stent or pancreatic duct guidewire-guided septal precut. We present a literature review of guidewire-assisted cannulation as a primary endoscopic method and the precut technique for the facilitation of selective biliary access.

BACKGROUND: Diastolic function can be assessed by Doppler-derived left ventricular(LV) filling patterns. E/A ratio<1 and prolongation of isovolumic relaxation time(IVRT) are diagnostic of impaired relaxation of left ventricle during diastole. In early stage of acute myocardial infarction, myocardial stiffness can normalize the E/A ratio and mask the Doppler indexes of abnormal relaxation in patients with acute myocardial infarction. METHODS: LV filling patterns were studied with Doppler echocardiography in 10 healthy subjects and 27 patients with recent acute myocardial infarction. Cardiac catherterization was performed in the 11+/-2 days after onset of acute myocardial infarction and left ventricular end-diastolic pressure(LVEDP) and myocardial stiffiness index(MSI) were studied. RESULTS: In patients with acute myocardial infarction, IVRT was significantly prolonged ; E/A ratio and deceleration time were decreased but not significantly different from those of normal subjects. In the patient's group of E/A>1,IVRT and atrial filling fraction(AFF) were significantly shortened, and LVEDP was significantly increased, compared to those of the patient's group of E/A<1. But ejection fraction was similar in both groups. In the patients with acute myocardial infarction, E/A ratio and LVEDP showed good correlation(r=0.64, p<0.05). MSI was increased in the patient's group of E/A>1 and also was well correlated with LVEDP(r=0.8, p<0.05). CONCLUSIONS: Thus we conclude that normal of increased E/A ratio in recent acute myocardial infarction may reflect increased LVEDP due to increased myocardial stiffness.

Journal of the Korean Academy of Family Medicine 2004;25(6):462-468
BACKGROUND: This study was done to examine the relationship between distorted self-perception of body weight and some sociodemographic factors in Korean adults. METHODS: This study was conducted among 14,621 adults (men 10,833, women 3,788), who visited Ulsan University Hospital Health Promotion Center to take a routine health examination. The objective body weight status was classified as underweight, normal, overweight, and obesity by body mass index. We compared the self- perception of body weight with in objective body weight status. We used multiple logistic regression to assess the odds ratio for distorted self-perception of body weight by age, marital status, monthly income, and level of education. RESULTS: Among the total 72.8% of obese men had a distorted self-perception of being slightly excess, 48% of overweight men considered themselves as just about right, and 39.5% of men with normal body weight as underweight. In women, 36.5% with normal body weight had a distorted self-perception of being slightly excess or very excess. In both men and women who were overweight or obesity, the distorted self-perception of being just about right was increased with higher age and lower education. The odds ratio of distorted self-perception in normal as being slightly excess or very excess was higher in women with higher income and higher education. CONCLUSION: In both men and women, many people had a distorted self-perception of Body weight. Some sociodemographic factors were found to be related to the self- perception of body weight.
