Background: Although poor oral health is a common comorbidity in individuals with airflow limitation (AFL), few studies have comprehensively evaluated this association. Furthermore, the association between oral health and the severity of AFL has not been well elucidated. Methods: Using a population-based nationwide survey, we classified individuals according to the presence or absence of AFL defined as pre-bronchodilator forced expiratory volume in 1 second/forced vital capacity < 0.7. Using multivariable logistic regression analyses, we evaluated the association between AFL severity and the number of remaining teeth; the presence of periodontitis; the Decayed, Missing, and Filled Teeth (DMFT) index; and denture wearing. Results: Among the 31,839 participants, 14% had AFL. Compared with the control group, the AFL group had a higher proportion of periodontitis (88.8% vs. 79.4%), complete denture (6.2% vs. 1.6%), and high DMFT index (37.3% vs. 27.8%) (P < 0.001 for all). In multivariable analyses, denture status: removable partial denture (adjusted odds ratio [aOR], 1.12; 95% confidence interval [95% CI], 1.04–1.20) and complete denture (aOR, 1.52; 95% CI, 1.01– 2.05), high DMFT index (aOR, 1.13; 95% CI, 1.02–1.24), and fewer permanent teeth (0–19;aOR, 1.32; 95% CI, 1.12–1.52) were significantly associated with AFL. Furthermore, those with severe to very severe AFL had a significantly higher proportion of complete denture (aOR, 2.41; 95% CI, 1.11–3.71) and fewer remaining teeth (0–19; aOR, 2.29; 95% CI, 1.57–3.01). Conclusion Denture wearing, high DMFT index, and fewer permanent teeth are significantly associated with AFL. Furthermore, a reduced number of permanent teeth (0–19) was significantly related to the severity of AFL. Therefore, physicians should pay attention to oral health in managing patients with AFL, such as chronic obstructive pulmonary disease.

The objectives of this study were to assess the clinical outcomes of adults with Ebstein Anomaly (EA) according to their treatment modalities. All adult EA patients diagnosed between October 1994 and October 2014 were retrospectively evaluated by medical record review. Total 60 patients were categorized into 3 groups according to their treatment strategy, i.e. non-operative treatment (Group I, n = 23), immediate operative treatment (Group II, n = 27), and delayed operative treatment (Group III, n = 10). A composite of major adverse cardiac and cerebrovascular events (MACCE) and factors associated with MACCE were assessed in each treatment group. MACCE occurred in 13.0% patients in Group I, 55.6% patients in Group II and 50% in Group III (P = 0.006). Event free survivals at 5 years were 90% in Group I, 52.7% in Group II, 50.0% in Group III (P = 0.036). Post-operatively, most patients showed improvement on clinical symptoms. However, event free survival rate was lower in patients with operation compared to those with non-operative treatment (58.7% vs. 90.9%; P = 0.007). Major arrhythmic event occurred more frequently even after surgical ablation (50.0% vs. 20.0%; P = 0.034). Re-operation was more frequent in patients underwent delayed surgery compared to those with immediate surgery (50.0% vs. 18.5%; P = 0.001). Current guideline to decide patient's treatment strategy appeared to be appropriate in adult patients with EA. However, surgical ablation for arrhythmia was not enough so that concomitant medical treatment should be considered. Therefore, attentive risk stratification and cautious decision of treatment strategy by experienced cardiac surgeon are believed to improve clinical outcome.

BACKGROUND/AIMS: Planned endoscopic submucosal dissection with snaring (ESD-S) is thought to shorten operating time spent on submucosal dissection, but may lead to uncertainty of en bloc resection or to a possible increase in tumor-positive margins. The purpose of the present study is to investigate the feasibility of ESD-S as a planned procedure for gastric adenoma. MATERIALS AND METHODS: The medical records of 99 patients who underwent ESD-S or ESD for gastric adenoma between May 2011 and May 2012 were retrospectively reviewed. We analyzed the differences between the ESD-S and the ESD groups, focusing on rates of en bloc resection and pathologic complete resection, mean operation time, and complications. RESULTS: The mean operation time was significantly lower in the ESD-S group than in the ESD group (19.9+/-11.2 vs. 33.8+/-19.9, P=0.012). Cases with an operation time under 30 minutes were more frequent in the ESD-S group (88.9% vs. 48.1%, OR=8.615, 95% CI=2.949~25.168). There were no significant differences in en bloc resection, histologic complete resection, or complication rates between the two groups. CONCLUSIONS: ESD-S has a time advantage over ESD with a comparable compete resection rate. ESD-S can be considered a planned method for available early gastric adenoma.

BACKGROUND/AIMS: Previous studies have reported that the frequency of re-diagnosing as carcinoma after endoscopic resection of gastric adenoma ranges between 6% and 47%. Therefore, specific endoscopic findings have been used to predict re-diagnosing as carcinoma after endoscopic resection of gastric adenoma at our center. We evaluated whether there is a use for these indicators for predicting carcinoma as a final diagnosis in forceps biopsy-proven adenomas. MATERIALS AND METHODS: We investigated 378 tissue samples from 308 patients. Classification of specimens as adenoma and carcinoma was based on postresection specimen. Endoscopic findings were reviewed for tumor location, size, gross appearance, surface nodularity, central concavity, surface color, and presence of ulcers. These variables were analyzed and compared between the adenoma group (275 cases) and the carcinoma group (103 cases), assigned based on post-resection diagnosis. RESULTS: The mean patient age was 61, and 227 of the patients were male. The mean lesion diameter was 14.9+/-8.1 mm in the adenoma group and 17.9+/-9.3 mm in the carcinoma group. A lesion size of 15 mm or greater, depressed appearance, surface nodularity, central concavity, and presence of high-grade dysplasia were all independently associated with re-diagnosing as carcinoma after endoscopic resection. CONCLUSIONS: Lesion size of 15 mm or greater, depressed-type appearance, central concavity, and nodular surface are feasible predictors of carcinoma as a final diagnosis in forceps biopsy-proven adenomas. Physicians need to recommend immediate endoscopic resection for forceps biopsy-proven adenomas with these four independent features so as not to miss the optimal window for treatment.

Aneurysm of the mitral valve, although uncommon, occurs most commonly in association with infective endocarditis of the aortic valve and true mitral valve aneurysm is a rare cause of mitral regurgitation. We report a case with perforated mitral valve aneurysm in the posterior leaflet without concurrent infective endocarditis initially mistaken diagnosis of cystic mass, which was confirmed at operation with successful mitral valve annuloplasty.

BACKGROUND: The objective of this study was to investigate the association between nonalcoholic fatty liver disease (NAFLD) and carotid artery atherosclerosis beyond metabolic disorders. METHODS: We studied 320 non-diabetic patients with ultrasonographically diagnosed NAFLD and 313 non-diabetic patients without NAFLD who have less than 40 g alcohol/week drinking history. Carotid atherosclerotic burden was assessed by carotid intima-media thickness (IMT) and plaque. All subjects were divided to the metabolic syndrome (MetS) according to International Diabetes Federation criteria. RESULTS: NAFLD patients had a significantly increased mean carotid IMT (0.79 +/- 0.18 vs. 0.73 +/- 0.13 mm; p < 0.001) than those without the condition. The prevalence of increased IMT, defined as IMT > or = 1 mm, and carotid plaque were 52.5% and 34.1% in the patients with NAFLD vs. 35.8% and 18.8% in the patients without this condition (p < 0.001). The difference in IMT and prevalence of plaque was also significant even in patients without MetS as well as those with MetS (all p < 0.05). NAFLD-associated adjusted odds ratio for increased IMT was 1.236 [95% confidence interval (CI), 1.023-1.467, p = 0.016] without MetS and 1.178 (95% CI, 1.059-1.311, p = 0.003) with MetS. NAFLD-associated adjusted odds ratio of carotid plaque was 1.583 (95% CI, 1.309-1.857, p = 0.024) without MetS and 1.536 (95% CI, 0.512-4.604, p = 0.444) with MetS. CONCLUSION: NAFLD is significantly associated with carotid atherosclerosis in non-diabetic outpatients even without MetS. Carotid screening for NAFLD might be beneficial for assessment of future atherosclerotic complications.

BACKGROUND/AIMS: The aim of this study was to identify changes in left ventricular (LV) performance in patients with a myocardial bridge (MB) in the left anterior descending coronary artery during resting and in an inotropic state. METHODS: Myocardial strain measurement by speckle-tracking echocardiography and conventional LV wall-motion scoring was performed in 18 patients with MB (mean age, 48.1 +/- 1.7 years, eight female) during resting and intravenous dobutamine challenge (10 and 20 microg/kg/min). RESULTS: Conventional LV wall-motion scoring was normal in all patients during resting and in an inotropic state. Peak regional circumferential strain increased dose dependently upon dobutamine challenge. Longitudinal strains of the anterior and anteroseptal segments were, however, reduced at 20 microg/kg/min and showed a dyssynchronous pattern at 20 microg/kg/min. Although there were no significant differences in radial strain and displacement of all segments at rest compared with under 10 microg/kg/min challenge, radial strain and displacement of anterior segments at 20 microg/kg/min were significantly reduced compared with posterior segments at the papillary muscle level (44.8 +/- 14.9% vs. 78.4 +/- 20.1% and 5.3 +/- 2.3 mm vs. 8.5 +/- 1.8 mm, respectively; all p < 0.001), and showed plateau (40%) or biphasic (62%) patterns. CONCLUSIONS: Reduced LV strain of patients with MB after inotropic stimulation was identified. Speckle-tracking strain echocardiography identified a LV myocardial dyssynchrony that was not demonstrated by conventional echocardiography in patients with MB.

PURPOSE: Althoughpancreas injury is rare in abdominal trauma,it posesa challengeto the surgeon because its clinicalfeaturesare not prominentand the presence of main duct injurycannot be easily identified by imaging studies. Furthermore, severe pancreas injuries require a distal pancreatectomy or a pancreaticoduodnectomy which are associated considerable morbidity and mortality. We reviewed the clinical features of and outcomes for patients with pancreas injury. METHODS: For 10 years from Jan. 2001 to Dec. 2010, thirty-four patients were diagnosedas having pancreas injury by using an explo-laparotomy. Patients successfully treated bynon-operative management were excluded. Patients were divided into early (n=18) and delayed surgery groups (n=11) based on an interval of 24hours between injury and surgery. The clinical features of and the outcomes for the patients in both groups were compared. RESULTS: Males were more commonly injured (82.4% vs.17.6%). The mean age was 37.2 years. The injury mechanisms included vehicle accidents (62.9%, 22/34), assaults (20%, 7/34), and falls (11.4%, 3/34)). The head and neck of the pancreas was most commonly injured, followed by the body and the tail (16, 12, and 6 cases). Of the 34 patients, 26 (76.5%) patients had accompanying injuries. Grade 1 and 2 occurred in 14 (5 and 9) patients, and grade 3, 4, and 5 occurred in 20 (16, 3, and 1) patients. The early and delayed surgery groups showed no difference in surgical outcomes. Two patients with grade 3 in the early surgery group died after surgery,one due tomassive hemorrhage and the other due to septic shock. Of the five patients initially managed non-operatively,three developed peripancreatic necrosis and two developed pseudocyst. All five patients were successfully cured by surgery. CONCLUSION: All cases of pancreas injury in this study involved blunt injury, and accompanying injury to major vessels or the bowel was the major cause of mortality. Surgery delayed for longer than 24 hours after was not associated with adverseoutcomes.
