BACKGROUND/AIMS: In Korea, the prevalence of pancreatic cancer (PC) in general population has been reported as 7 in 100,000. However, that in diabetes mellitus (DM) has not been elucidated yet. This study was designed to estimate the prevalence of PC among DM patients, and characterize and compare the patients with DM with and without PC. METHODS: 5,082 patients (4,890 DM without PC, 78 PC with DM, and 114 PC without DM) were enrolled from Korea University Guro Hospital during a period of 4 years between January 2004 and January 2008. RESULTS: The prevalence of PC in DM patients was 1.6% and that of DM in PC patients was 40.6%. No significant differences in the clinical characteristics except HbAIc and ALP were observed between PC patients with DM and without DM. Among 78 PC patients with DM, DM was diagnosed in 19 (29.4%) and 29 (37.1%) patients concomitantly or within 2 years prior to the diagnosis of PC, respectively. Among the cases with recent onset DM (less than 2 years' duration), the disease duration of DM before the diagnosis of PC was less than 1 year in 14 patients (17.9%) and 1 to 2 years in 15 patients (19.2%). DM patients with PC were found to have significantly higher ALT, total bilirubin, and ALP levels than in DM patients without PC. CONCLUSIONS: The prevalence of PC in DM patients was 1.6% and was higher than in the general population. Recent onset DM was frequent in PC patients (less than 2 years' duration). We recommend close follow-up for at least 2 years in new-onset diabetes.

Evidence suggests that diabetes mellitus (DM) is associated with idiopathic pulmonary fibrosis (IPF). According to the new IPF guidelines, high-resolution computed tomography (HRCT) is an essential means of diagnosing IPF. We investigated the relationship between IPF and DM in patients treated between 2003 and 2007. Newly diagnosed IPF patients in large university teaching hospitals in Korea were enrolled from January 2003 to December 2007. We retrospectively analyzed 1,685 patients using the interstitial lung disease (ILD) registry. In total, 299 IPF patients (17.8%) also had DM. The mean age of our subjects was 68.0 +/- 9.4 yr. HRCT showed significantly more reticular and honeycomb patterns in IPF patients with DM than in IPF patients without DM (P = 0.014, P = 0.028, respectively). Furthermore, significantly higher incidences of hypertension, cardiovascular diseases, and other malignancies (except lung cancer) were found in IPF patients with DM than in IPF patients without DM. In conclusion, IPF patients with DM are more likely to have the usual interstitial pneumonia (UIP) pattern, including reticular and honeycomb patterns, on HRCT than are those without DM.

OBJECTIVETo observe the clinical characteristics, treatment options and outcome of diabetic patients with non-ST elevation acute coronary syndromes (NSTEACS).

METHODSConsecutive patients admitted with NSTEACS from 38 centers in north China were enrolled. Medical histories, clinical characteristics, treatments and outcomes were evaluated and follow-up was made at 6, 12, and 24 months after their initial hospital admission. Cumulative event rates were compared between diabetic and non-diabetic patients.

RESULTSThere were 420 diabetic patients out of 2294 NSTEACS patients (18.3%). Diabetic patients were older [(64.9 ± 6.7) years vs. (62.3 ± 8.6) years, P < 0.01], more often women (48.1% vs. 35.3%, P < 0.05) and were associated with higher baseline comorbidities such as previous hypertension, myocardial infarction, congestive heart failure and stroke than non-diabetic patients. The incidence of antiplatelet therapy (92.1% vs. 95.0%, P < 0.05), coronary angiography (30.0% vs. 36.3%, P < 0.05) and revascularization (12.1% vs.18.8%, P < 0.05) was lower in patients with diabetes than non-diabetic patients. In hospital and 2-year mortality as well as the incidence of congestive heart failure and composite outcomes of myocardial infarction, stroke, congestive heart failure and death were substantially higher in diabetic patients compared with non-diabetic patients. Multivariate Cox regression analysis revealed that age ≥ 70 years, diabetes, previous myocardial infarction, previous congestive heart failure, systolic blood pressure less than 90 mm Hg (1 mm Hg = 0.133 kPa) and heart rate more than 100 bpm at admission were risk factors for 2-year death.

CONCLUSIONIn NSTEACS, diabetes is associated with higher rate of in-hospital and 2-year death, congestive heart failure and composite outcomes of myocardial infarction, stroke, congestive heart failure and death. Diabetes mellitus is a major independent predictor of 2-year mortality post NSTEACS. Status of antiplatelet therapy, coronary angiography and revascularization should be improved for diabetic patients with NSTEACS during hospitalization.

This study was done to evaluate prospectively the clinical significance of colonic diverticulosis. In the 1,030 consecutive outpatients undergoing colonoscopy, the information on the demographics, the patterns of bowel symptoms, and the prevalence of colon polyp were analyzed according to the presence of colonic diverticulosis. The mean age of 1,030 patients were 52.2 yr and 59.3% were male. The prevalence of diverticulosis was 19.7% (203/1,030). Of 203 diverticulosis patients 85.2% were in proximal group, 5.4% in distal group and 9.4% in both group. Six (3.0%) patients were found to have diverticulitis. Multivariate logistic regression analysis showed that an old age, diabetes and the presence of polyp were significant factors associated with proximal or both diverticulosis. A significant difference was demonstrated between the patients of distal diverticular group and the controls for the symptom frequency scores within the previous 4 weeks. The items, which showed difference, were hard stool, urgency, flatus, chest discomfort and frequent urination. In conclusion, old age, diabetes and the presence of colon polyp were associated with proximal diverticulosis. The temporal symptoms were more frequent in distal diverticulosis than in proximal diverticulosis in the study subjects.

INTRODUCTIONThis study aims to evaluate the results of foot screening performed in a study population of 2137 diabetics (3926 feet) screened from 2006 to 2008 by the National University Hospital (NUH) multi-disciplinary team for diabetic foot problems.

MATERIALS AND METHODSA standardised protocol was designed. Foot screening consisted of detailed history taking and clinical examination including assessment for sensory neuropathy by Semmes Weinstein monofilament (SWMF) and neurothesiometer and assessment of vasculopathy by ankle-brachial index (ABI) and total body irradiation (TBI). The foot screening was performed by a trained staff nurse. All patients were classified according to King's College Classification.

RESULTSMajority of the patients were in the fifth (27.9%) and sixth (30.0%) decades of life. Two thousand sixty-four had type II diabetes, and only 73 had type I diabetes. Neuropathy was found in 1307 (33.3%) feet based on 5.07 SWMF. Vasculopathy was recorded in 510 (13.0%) and 546 (13.9%) feet based on ABI <0.8 and TBI <0.7. According to King's Classification, 1069 (50.0%) were Stage 1: Normal and 615 (28.8%) were Stage 2: At-Risk.

CONCLUSIONFoot screening should be performed as early as possible to detect "At-Risk" feet and prevent the development of diabetic foot complications, thereby further reducing the risk of major amputations.

BACKGROUND: Most of the known risk factors associated with ischemic heart disease are based on studies from Western countries; there is only limited information on Korean populations. This study was designed to analyze age related differences in epidemiologic and clinical characteristics in patients who were admitted for coronary angiography for the evaluation of ischemic heart disease. METHODS: As part of the multicenter KCAR (Korean Coronary Artery disease Registry) Study, the clinical data of 6,549 patients, who were evaluated at the cardiac catheterization laboratory by coronary angiography, at seven university hospitals in Korea from March 1999 to December 2005, were registered into the KCAR database and analyzed. All patients were divided into three groups according to age: age < or =40, age 41-70 and age > or =71. All demographic and coronary angiographic features were analyzed for the different groups. RESULTS: The demographic data showed that compared to the older patients young patients < or =40 had a higher prevalence of males and smokers, but a lower prevalence of hypertension, diabetes and prior history of stroke and myocardial infarction. For the lipid profiles, the younger patients had much higher levels of total cholesterol, triglycerides and LDL-cholesterol than the older groups; however, there was no difference in the HDL-cholesterol levels among the three age groups. The most common component of the metabolic syndrome was obesity (79%) in the younger patients and hypertension (92%) in the older patients. The most common reason for presentation was ST-segment elevated myocardial infarction in the younger patients and unstable angina in the older patients. CONCLUSIONS: Ischemic heart disease in younger adults < or =40 had different demographic characteristics and clinical presentation than older patients.

BACKGROUND/AIMS: Patients with diabetes mellitus (DM) are more likely to have a pyogenic liver abscess with gas formation, which is associated with higher morbidity and mortality. The morbidity and mortality in pyogenic liver abscess are also higher in DM patients than in non-DM patients. This study evaluated the morbidity, mortality, and clinical features in patients with gas-forming liver abscesses associated with DM. METHODS: Among 379 cases of pyogenic liver abscess excluding malignancy from January 2001 through December 2009, 25 patients treated for pyogenic-gas-forming liver abscesses were reviewed retrospectively. We compared the morbidity, mortality, and clinical findings in patients with pyogenic-gas-forming liver abscesses between DM and non-DM patients. RESULTS: Gas formation was present in 25 (6.6%) of 379 cases with pyogenic liver abscess. DM was combined with gas-forming liver abscesses in 19 cases (76%). The most common organism responsible for the gas formation was Klebsiella pneumoniae (82%). Complications were present in 23 cases (92%) of gas-forming liver abscesses, with pulmonary complications (especially pleural effusion) being the most common (n=14, 61%). Four patients (16%) died of sepsis. CONCLUSIONS: Gas-forming liver abscesses are not uncommon in cases of pyogenic liver abscesses and are associated with high morbidity and mortality rates. The clinical manifestations and complications do not differ significantly between DM and non-DM patients.

Previous epidemiologic studies have shown the clinical association between non-alcoholic fatty liver disease (NAFLD) and cardiovascular disease (CVD). However, there is only limited information about the effect of NAFLD on the development of hypertension. Accordingly, we investigated the clinical association between NAFLD and prehypertension. A prospective cohort study was conducted on the 11,350 Korean men without prehypertension for 5 yr. The incidences of prehypertension were evaluated, and Cox proportional hazard model was used to measure the hazard ratios (HRs) for the development of prehypertension according to the degree of NAFLD (normal, mild, moderate to severe). The incidence of prehypertension increased according to NAFLD states (normal: 55.5%, mild: 63.7%, moderate to severe: 70.3%, P<0.001). Even after adjusting for multiple covariates, the HRs (95% confidence interval) for prehypertension were higher in the mild group (1.18; 1.07-1.31) and moderate to severe group (1.62; 1.21-2.17), compared to normal group, respectively (P for trend <0.001). The development of prehypertension is more potentially associated with the more progressive NAFLD than normal and milder state. These findings suggest the clinical significance of NAFLD as one of risk factors for prehypertension.
