Immunoglobulin G4-related sclerosing cholangitis (IgG4-SC) is rare disease which is steroid-responsive and often associated with IgG4 related systemic disease such as autoimmune pancreatitis. It is characterized by increased serum IgG4 and IgG4-positive lymphoplasmacytic infiltration in bile ducts. It is often difficult to distinguish IgG4-SC to hilar cholangiocarcinoma if it manifests as an isolated bile duct. We report a case of 79-year-old woman with IgG4-SC which was difficult to distinguish hilar cholangiocarcinoma due to similar clinical and radiologic findings, showing good therapeutic effect after a 2-week steroid trial.

This study attempted to calculate and investigate the incidence of hospitalized acute myocardial infarction (AMI) and stroke in Korea. Using the National Health Insurance claim data, we investigated patients whose main diagnostic codes included AMI or stroke during 2006 to 2010. As a result, we found out that the number of AMI hospitalized patients had decreased since 2006 and amounted to 15,893 in 2010; and that the number of those with stroke had decreased since 2006 and amounted to 73,501 in 2010. The age-standardized incidence rate of hospitalized AMI, after adjustment for readmission, was 41.6 cases per 100,000-population in 2006, and had decreased to 29.4 cases in 2010 (for trend P < 0.001). In the case of stroke was estimated at 172.8 cases per 100,000-population in 2006, and had decreased to 135.1 cases in 2010 (for trend P < 0.001). In conclusion, the age-standardized incidence rates of both hospitalized AMI and stroke in Korea had decreased continuously during 2006 to 2010. We consider this decreasing trend due to the active use of pharmaceuticals, early vascular intervention, and the national cardio-cerebrovascular disease care project as the primary and secondary prevention efforts.

BACKGROUND: Sleep is an essential restorative physiologic phenomenon. Impaired sleep results in significant negative effect to the health. Symptoms like sleep initiation difficulty, frequent awakening, severe snoring have related to poor sleep quality. We studied frequency and compared the characteristics of common sleep disorders at family practice. METHODS: We surveyed patients over 18 years of age and their guardians who visited 16 familial practices for 6 days. We investigated sleep characteristics, frequency of sleep disorder and associated factors by questionnaires and analyzed by frequency analysis, Spearman's correlation coefficient, multiple logistic regression. RESULTS: We enrolled 1,117 participants. Older participants were more likely to report early sleep onset and off time, short sleep duration. Mean number of awakening during a typical night is 1.69. Female complained difficulties in initiation and maintenance of sleep more than male. A total of 32.5% had these insomnia symptoms and related to hypertension, stroke, stress, arthralgia, depression, urological disorder. 31.1% had excessive daytime sleepiness, related to stress, arthralgia, depression. Loud snoring and gasp for breath showed positive correlation between male, high BMI. Disrupted sleep over 3 times was related to old age, female, diabetes, hypertension, stroke, stress, arthralgia, depression. Restless leg syndrome were high in elderly, high BMI, stress, arthralgia and depression. CONCLUSION: About one in three who visit in primary medical practice have sleep disorder symptoms like insomnia, daytime fatigue, snoring. 3% of them have gasp for breath, 8% have restless leg syndrome.

BACKGROUND/AIMS: De novo colorectal carcinoma shows more aggressive behavior including submucosal invasiveness. Both p53 and cyclo-oxygenase-2 (COX-2) have been shown to be involved in colon carcinogenesis, progression from adenoma to carcinoma, and submucosal invasion by tumor. We performed this study to evaluate the expression of p53 and COX-2 protein in de novo carcinoma, compared with ex-adenoma carcinoma. METHODS: Twenty three flat adenomas, 19 ex-adenoma carcinomas, 6 de novo carcinomas were included in this study. The expression of p53, COX-2 and Ki-67 were examined immunohistochemically. RESULTS: Both ex- adenoma carcinomas and de novo carcinomas showed similar size and shape. Positive staining for p53 was detected in 3 of 23 (13%) flat adenomas, in 11 of 19 (57.8%) ex-adenoma carcinomas (p<0.05), and in 1 of 6 (16.6%) de novo carcinomas. Increased numbers of COX-2 positive tumor cells were observed in 1 of 23 (4.3%) flat adenomas, in 2 of 19 (10.5%) ex-adenoma carcinomas, and in 3 of 6 (50%) de novo carcinomas. COX-2 positive expression showed increased tendency in de novo carcinoma (p=0.073). There was no correlation between COX-2, p53, and Ki-67 expression. CONCLUSION: De novo carcinoma shows increased tendency of COX-2 expression, but decreased p53 expression when compared to ex-adenoma carcinoma. These immunohistochemical findings are in accordance with the fact that de novo carcinoma has no preceding adenoma, with more frequent submucosal invasion despite the small lesion size.

BACKGROUND: This study compared the bronchodilator efficacy and safety of tiotropium inhalation capsules (18microgram once daily) with a ipratropium metered dose inhaler (2 puffs of 20microgram q.i.d.) in patients with chronic obstructive pulmonary disease (COPD). METHOD: After the initial screening assessment and a two-week run-in period, patients received either tiotropium 18microgram once daily or ipratropium 40microgram four times daily over a period of 4 weeks in a double blind, double dummy, parallel group study. The outcome measures were the lung function, the daily records of the peak expiratory flow rate (PEFR), the patients' questionnaire, and the use of concomitant salbutamol. The forced expiratory volume in one second (FEV1) and the forced vital capacity (FVC) were measured 5 minutes before inhalation, and 0.5, 1, 2 and 3 hours after inhaling the study drug on days 0, 14 and 28. RESULT: In 16 centers, 134 patients with a mean (SD) age of 66 (7) years and a predicted FEV1 of 42 (12)% were analyzed. The trough FEV1 response was significantly higher in the tiotropium group than in the ipratropium group after a four-week treatment period. The weekly mean morning PEFR of the tiotropium group was consistently higher than that of the ipratropium group during the 4-week treatment period with differences ranging from 12.52 to 13.88 l/min, which were statistically significant. Tiotropium was well tolerated by the COPD patients during the 4-week treatment period and had a similar safety profile to ipratropium. CONCLUSION: This study shows that tiotropium administrated once daily has a superior bronchodilator effect with a similar safety profile in treating COPD patients compared with ipratropium, inhaled four times daily.

The purpose of this prospective study was to determine whether using magnetic resonance imaging (MRI) for early screening for brain metastases (BM) can improve quality of life, survival in patients with non-small cell lung cancer (NSCLC). The study group comprised 183 patients newly diagnosed with NSCLC. All patients underwent limited brain MRI and routine workups. The control group comprised 131 patients with NSCLC who underwent limited brain MRI only if they had neurologic symptoms. The incidence of BM was 20.8% (38/183) in the study group and 4.6% (6/131) in the control group. The rate of upstaging based on the MRI data was 13.5% (15/111) overall and 15.9% (11/69) in patients that had been considered initially to be resectable surgically. There was no significant difference in survival outcome between the groups. Patients who had BM alone had a greater overall survival time (49 weeks) than those who had multiple systemic metastases (27 weeks; p=0.0307). In conclusions, limited brain MRI appears to be a useful, costeffective method to screen for BM at the time of initial staging. And it may facilitate timely treatment of patients with NSCLC and improve their survival and quality of life.

Dieulafoy's lesion is a very rare cause of gastrointestinal bleeding that occurs after rupture of an exposed submucosal artery. The majority of lesions are found in the stomach, but rarely it has also been identified in the duodenum, small bowel, colon and rectum. We describe a 78-year-old female with chronic renal failure who presented with melena and was subsequently found to have a Dieufaloy-like lesion in the stomach. The bleeding was successfully managed by endoscopic hemoclipping. During the follow-up, massive gastrointestinal bleeding was developed by a Dieulafoy-like lesion in the rectum. This lesion was managed by endoscopic band ligation, but there was recurrent bleeding from the ulcer site. The ulcer site was locally excised and primary closure was carried out.

BACKGROUND: The long-term results of combined mitral valve repair and aortic valve replacement (AVR) have not been well evaluated. This study was performed to investigate the early and long-term results of mitral valve repair with AVR. MATERIAL AND METHOD: We retrospectively reviewed 45 patients who underwent mitral valve repair and AVR between September 1990 and April 2002. The average age was 47 years; 28 were men and 17 women. Twelve patients had atrial fibrillation and three had a previous cardiac operation. The mitral valve disease consisted of pure insufficiency (MR) in 34 patients, mitral stenosis (MS) in 3, and mixed lesion in 8. Mitral valve disease was due to rheumatic origin in 24 patients, degenerative in 11, annular dilatation in 8, and ischemia or endocarditis in 2. The functional anatomy of mitral valve was annular dilatation in 31 patients, chordal elongation in 19, leaflet thickening in 19, commissural fusion in 13, chordal fusion in 10, chordal rupture in 6, and so on. Aortic prostheses used included mechanical valve in 32 patients, tissue valve in 12, and pulmonary autograft in one. The techniques of mitral valve repair included annuloplasty in 32 patients and various valvuloplasty of 54 techniques in 29 patients. Total cardiopulmonary bypass and aortic cross clamp time were 204+/-62 minute and 153+/-57 minutes, respectively. RESULT: Early death was in one patient due to low output syndrome (2.2%). After follow up of 57+/-37 months, late death was in one patient and the actuarial survival at 10 years was 96+/-4%. Recurrent MR developed grade II or III in 11 patients and moderate MS in 3. Three patients required reoperation for valve-related complications. The actuarial freedom from recurrent MR, MS, and reoperation were 64+/-11%, 86+/-8%, and 89+/-7% respectively. CONCLUSION: Combined mitral valve repair with AVR offers good early and long-term survival, and adequate techniques and selection of indication of mitral valve repair, especially in rheumatic disease, are prerequisites for better long-term results.

In off-pump coronary artery bypass grafting (CABG), multiple proximal anastomosis may increase the risk of cerebral embolism (air, debris) and aortic injury (dissection, pseudoaneurysm). Radial artery (RA) has no intraluminal valve such as saphenous vein. We applied Cabrol technique using aortic root replacement for proximal anastomosis in off-pump CABG. Cabrol technique using RA graft can reduce numbers of proximal anastomosis and reduce number of aortic manipulation in off-pump CABG. We report a Cabrol technique for proximal anastomosis in off-pump CABG with RA graft.

BACKGROUND: This study was undertaken to analyze the outcome of composite valve graft replacement(CVGR) for the treatment of aneurysms of the ascending aorta involving the aortic root. MATERIAL AND METHOD: Between April 1995 and June 2001, 56 patients had replacement of the ascending aorta and aortic root with a composite graft valve and were reviewed retrospectively. Aortic regurgitation was present in 50 patients(89%), Marfan's syndrome in 18 patients(32%), and bicuspid aortic valve in 7(12.5%). The indications for operation were annuloaortic ectasia(AAE) in 30 patients(53.6%), aortic dissection in 13(23.2%), aneurysms of the ascending aorta involving aortic root in 11(19.6%), and aortitis in 2(3.6%). Cardiogenic shock due to the aortic rupture was present in 2 patients. Nine patients(16%) had previous operations on the ascending aorta or open heart surgery. The operative techniques used for CVGR were the aortic button technique in 51 patients(91%), the modified Cabrol technique in 4, and the classic Bentall technique in 1. The concomitant procedures were aortic arch replacement in 24 patients(43%), coronary artery bypass graft in 8(14.3%), mitral valve repair in 2, redo mitral valve replacement in 1, and the others in 7. The mean time of circulatory arrest, total bypass, and aortic crossclamp were 21+/-14 minutes, 186+/-68 minutes, and 132+/-42 minutes, respectively. RESULT: Early mortality was 1.8%(1/56). The postoperative complications were left ventricular dysfunction in 16 patients(28.6%), reoperation for bleeding in 7(12.5%), pericardial effusion in 2, and the others in 7. Fifty-three patients out of 55 hospital survivors were followed up for a mean of 23.2+/-18.7 months(1-75 months). There were two late deaths(3.8%) including one death due to the traumatic cerebral hemorrhage, and CVGR-related late mortality was 1.9%. The 1- and 6-year actuarial survival was 98.1+/-1.9% and 93.2+/-5.1%, respectively. Two patients required reoperation for complication of CVGR(3.8%) and two other patients required subsequent operations for dissection of the remaining thoracoabdominal aorta. The 1- and 6-year actuarial freedom from reoperation was 97.8+/-2.0% and 65.3+/-26.7%, respectively. CONCLUSION: This study suggests that aortic root replacement with a composite valve graft for a variety of aneurysms of the ascending aorta involving the aortic root is a safe and effective therapy, with good early and intermediate results. Careful follow-up of all patients following composite graft root replacement is important to long-term survival.
