Although acute acalculous cholecystitis (AAC) accounts for less than 10% of acute cholecystitis in the adult population, gangrene and perforation are much more frequent compared to the usual cases of acute cholecystitis (calculus cholecystitis). However, spontaneous biliary-enteric fistula is well recognized in AAC, 90% of which are cholecystoduodenal fistula (CDF) though it is an uncommon disorder. The majority of the CDF are caused by cholelithiasis. As patients are usually associated with complicated clinical illness, the diagnosis is often difficult to make and required surgery is often delayed. We have studied a rare complication of acute acalculous cholecystitis which was presented as intermittent upper gastrointestinal bleeding. Ulceration of the superficial branch of the cystic artery has been observed due to acalculous cholecystitis associated with a cholecystoduodenal fistula. We have performed a transfixing ligation of the bleeding vessel, cholecystectomy and simple closure of the CDF. We have finally made a diagnosis of early gallbladder cancer through a frozen section. There was no serious complication after the operation and the patient has achieved an uneventful recovery.

Syphilitic aortitis, passing out of our mind, is the most common systemic manifestation of late syphilis and is more typically manifestated 10 to 30 years afterward. This diagnosis has been made less frequently in recent decades than in the past, because of public awareness of syphilis and screening program. Treponema pallidum lodge within vasa vasorum, especially ascending aorta cause the histologic changes, which are responsible for the three major forms of symptomatic cardiovascular syphilis, including aortic insufficiency, coronary ostial stenosis, and aortic aneurysm. We experienced a case of syphilitic aortitis with aortic insufficiency and aortic aneurysm in a 48-year-old man presented with progressive dyspnea. Echocardiography, chest CT, and later surgical correction were performed and surgical specimen revealed the histologic finding consistent with syphilitic aortitis. We report this case with a review of the literature.

Recent studies of molecular biology have suggested that infection with human papillomavirus(HPV) is implicated in the pathogenesis of cervical carinoma. HPV infection alone, however, does not appear to be sufficient for the process of maliganant transformation, suggesting the requirement of additional cellular events. The mutation of p53, which is involved in negative control of cell proliferation, may play a role in the carcinogenesis of cervical carcinoma. The present study was designed to clarify the association between infection with HPV and p53 alteration in primary carcinoma of human uterine cervix. We investigated 46 prim-ary cervical carcinomas for the presence of HPV DNA by in situ hybridization(ISH) with probe specific for HPV 16/18, and examined the accumulation of p53 protein by immunohis-tochemistry(IHC) and the p53 alteration by polymerase chain reaction-single strand confor-mation polymorphism(PCR-SSCP) using formalin fixed, paraffin -embedded tissue. HPV DNA 16/18 was detected in 18 cases(39.1%) of 46 cervical carcinomas. The accumulation of p53 was identified in tumor cells: low level 43.5%(20/46) and high level 32.6% difference of positive reaction by IHC method. But there was no statistical significant between the infection of HPV and the accumulation of p53(p=0.847). Mutations in exons 4 through 9, where the vast majority of point mutations were reported in human neoplasms, were screened by PCR-SSCP analysis. Altered mobilities of the PCR product of p53 were also found in 9 cases(26.5%) of 34 cervical carcinoma: one in exon 4, four in exon 5/6, two in exon 7, and two in exon 8/9. The mutation of p53 was observed in 41.1%(19/46) respective of the result of IHC and PCR-SSCP, and there was slightly higher p53 alteration in HPV negative cases(23.8%, 11/46) than in HPV positive cases(17.4%, 8/46) without statistical significance(p=0.729). The conclusion of these observations suggests that HPV infection and alteration of p53 may play a critical role in tumorigenesis of carcinoma of the human uterine cervix independently, ant there is important difference in the tumorigenic pathway between two factors.

BACKGROUND: Perfusion scans are accurate predictors of postoperative lung function. There are few previous studies aimed at predicting the postoperative exercise capacity using the perfusion scanning and those that did reported contradictory results. METHOD: We prospectively studied the preoperative spirometric, exercise tests and perfusion scans from in 49 consecutive patients who were admitted to Inha University Hospital with surgically resectable lung cancer from Jan. 1998 to Jun. 1999 29 patients who had any condition affecting the lung function and exercise capacity, or refused a surgical resection or a follow-up study were excluded. Spirometric and exercise tests were performed 6 months after operation in 20 patients. RESULTS: The predicted postoperative FEV1, FVC and TLC correlated well with the following corresponding postoperative values : γs and p value, 0.809 and 0.000 for the FEV1 ; 0.895 and 0.000 for the FVC ; 0.741 and 0.006 for the TLC, respectively. The measured postoperative exercise values were slightly higher than the postoperative exercise values predicted, VO(2max) and Wr(max), were as 112% of VO(2max) predicted and 119% of WR(max) predicted. The change in FEV1, FVC and TLC had a weak correlation with the change in VO(2max) and WR(max). CONCLUSION: The perfusion scan was a useful tool for predicting the postoperative exercise capacity. However, they had a tendency to underestimate the exercise capacity, especially in the patients who had a pneumonectomy. A weak correlation between the change in lung function and exercise capacity was obseved.

Based on the unexpected Middle East respiratory syndrome (MERS) outbreak in Korea, it was established that the virus can spread easily, MERS exposure in hospitals carries an extreme risk for infection as well as mortality, and the sharing of information was essential for infection control. Although the incidence of exogenous infections related to contaminated endoscopes is very low, the majority of published outbreaks have been caused by various shortcomings in reprocessing procedures, including insufficient training or awareness. Ever since the inauguration of "Clinical Endoscopy" as an English-language journal of the Korean Society of Gastrointestinal Endoscopy in 2011, it has published several articles on disinfection of the endoscope and its accessories. Many Science Citation Index journals have also emphasized high-level disinfection of the gastrointestinal endoscope. Many papers have been produced specifically, since the outbreak of carbapenem-resistant Enterobacteriaceae in 2013. The recent review papers concluded that quality control is the most important issue among all the aspects of procedural care, including the efficiency of the gastrointestinal endoscopy unit and reprocessing room. Thorough reprocessing of endoscopes using high-level disinfection and sterilization methods may be essential for reducing the risk of infection.

Sparganosis is a parasitic infectious disease by sparganum which is a plerocercoid larva of spirometra, a kind of cestode. We experienced a case of intramural sparganosis of cecum presenting as chronic intermittent abdominal pain. A 39 year old man was hospitalized due to intermittent abdominal pain for 6 months and the operation was done under the impreesion of the intestinal tuberculosis or submucosal tumor of cecum after diagnostic work-up. Resected cecum revealed diffuse wall thickening and luminal narrowing. The microscopic findings showed a degenerated larva in the muscle layer with typical tissue reaction which was basically noncaseating cavitary granulomatous inflammation and many calcareous corpuscles which were pathognomonic features of cestode were prominent within the degenerated worm.

Background: Data on the relationship between Parkinson's disease (PD) and stroke have been conflicting, some studies showing a reduced risk of stroke during life because of low prevalence of vascular risk factors, and others indicating an increased risk of strokerelated death. The objective of this study is to determine the frequency of vascular risk factors in PD in relation to an unaffected control group and ischemic stroke patient group. Methods: We performed a case-control study on 206 consecutive PD patients, 207 ischemic strokes patients (served as "Disease" controls) and 138 age and sex matched normal subjects (served as controls), calculating multivariate risk estimates (odd ratio) for a series of established risk factors for vascular disease. Results: We found that (1) cigarette smoking (smoker, 0.078, CI=0.034-0.178; ex-smoker, 0.031, CI=0.011-0.088), and diabetes mellitus (0.340, CI=0.169-0.682) were significant less frequent in PD patients than controls, (2) cigarette smoking (smoker, 0.230, CI= 0.094-0.561; ex-smoker, 0.132, CI=0.050-0.348), hypertension (0.283, CI=0.175-0.459), diabetes mellitus (0.257, CI=0.136-0.486), previous stroke (0.063, CI=0.020-0.191), heart disease (0.344, CI=0.176-0.673) than ischemic stroke patients, respectively. Conclusion: We found the significant negative association of a series of vascular factors with PD, indicating a protective effect of PD against ischemic stroke.

Social networks are useful in the study of relationships between individuals or entire populations, and the ties through which any given social unit connects. Those represent the convergence of the various social contacts of that unit. Consequently, the term "social networking service" (SNS) became extremely familiar. Similar to familiar SNSs, International Digestive Endoscopy Network (IDEN) 2014 was based on an international network composed of an impressive 2-day scientific program dealing with a variety of topics for gastrointestinal (GI) diseases, which connects physicians and researchers from all over the world. The scientific programs included live endoscopic demonstrations and provided cutting-edge information and practice tips as well as the latest advances concerning upper GI, lower GI, and pancreatobiliary endoscopy. IDEN 2014 featured American Society for Gastrointestinal Endoscopy-Korean Society of Gastrointestinal Endoscopy (ASGE-KSGE)-joint sessions prepared through cooperation between ASGE and KSGE. Furthermore, IDEN 2014 provided a special program for young scientists called the 'Asian Young Endoscopist Award Forum' to foster networks, with many young endoscopists from Asian countries taking an active interest and participation.
