BACKGROUND AND OBJECTIVES: Diabetes is associated with a unique form of cardiomyopathy in the absence of atherosclerosis. The mechanisms of diabetic cardiomyopathy have not been defined, but is associated with early left ventricular (LV) diastolic dysfunction following an altered LV contractile performance. However, less attention has been paid to the right ventricular (RV) diastolic function in diabetes. Therefore, the changes in the RV ans LV filling dynamics, in patients with early type 2 diabetes, were investigated. SUBJECTS AND METHODS: The transtricuspid and trans-mitral flows were assessed by transthoracic Doppler echocardiography, at maximal inspiration and expiration, in 48 subjects (mean age: 62+/-9 years, M:F=16:32) with type 2 diabetes (Type 2 DM group) and 34 normal subjects (control group ; mean age:59+/-9 years, M:F=15:19, ranging from 45-75 years of age) with normal LV systolic function and ECG at rest. Subjects with diabetic complication, nephropathy (Cr >1.5 mg/dL), LVH and COPD were excluded. RESULTS: The mitral E/A ratio and DT (deceleration time) showed no significant difference between the type 2 DM and control groups. The LV and RV systolic functions also showed no significant difference between the two groups. However, the type 2 DM group had a lower tricuspid E/A ratio (0.98+/-0.25 vs. 1.17+/-0.21, p<0.001) and a longer tricuspid DT (241+/-65 msec vs. 208+/-51 msec, p=0.016) than the control group. CONCLUSION: The right ventricular diastolic function is frequently abnormal in early type 2 diabetes. This suggests that right ventricular diastolic dysfunction may be an important predictor for the early detection of diabetic cardiomyopathy.

Background and Objectives: To evaluate the cost-effectiveness of routine hypertension (HTN) screening as a part of the national health-screening program. Methods: Two aspects of cost-effectiveness were examined using the national general healthscreening program. First, the cost of case-finding was computed for 5-year interval age groups. Second, the cost per quality adjusted life years (QALYs) gained were estimated for 12 different scenarios varying examination starting age, pattern and interval compared with no screening. Results: The cost of finding one new HTN case was low as 26,284 Korean won (KRW) (approximately [approx.] United States Dollar 21) for 70–79 years old to as high as 70,552 KRW for 40–44 years old. Compared with no screening, the costs per QALYs of the following screening strategies were below the incremental cost-effectiveness ratio threshold (approx.KRW 30.5 million): first screening examination with the second confirmatory examination in adults aged ≥40 years every 3 years (KRW 10.2 million), every 2 years (KRW 13.2 million), or annually (KRW 19.9 million). One-way sensitivity analyses suggest that the results were mostly influenced by the sensitivity of the first screening examination, followed by the examination rate of the second confirmatory examination. Conclusions HTN screening as a part of routine national health screening program was cost-effective for adults aged 40 years or older. The most cost-effective HTN screening strategy was the first screening examination with the second confirmatory examination in aged 40 years or older every 3 years.

Relapsing polychondritis is a rare disease characterized by widespread destructive inflammatory lesions, involving cartilaginous tissue throughout the body. Commonly involved organs include the external ear, nose, joints, eyes, tracheobronchial tree, cardiovascular system and cutaneous tissues. Erythema nodosum or mesenteric panniculitis have sometimes been described in association with relapsing polychondritis, but cutaneous panniculitis is rarely reported in relapsing polychondritis. We report here a relapsing polychondritis patient who developed cutaneous panniculitis, which was resolved by corticosteroid therapy.

OBJECTIVES: Gallium 67(Ga-67) scintigraphy has been used to diagnose inflammatory and neoplastic diseases. We undertook a study to determine the clinical value of Ga- 67 renal scan in patients with various glomerular diseases. METHODS: Ga-67 scintigraphy was performed in 48 patients with various biopsy proven forms of renal diseases. Renal uptake in 48 patients images was graded as follow: Grade 0 = not visualization at 48 hours: 1 = faintly visualize: 2 = equal to uptake in spine: 3 = greater than over the spine: 4 = greater than activity over the liver. RESULTS: 1) Of the 48 patients, 31 were male, and mean age was 32 years. 11 patients had hypertension and 29 patients had hematuria. 2) Positive scintigram were seen in 40 of 48(83%) cases. In results of renal biopsy, IgA nephropathy(IgAN) was 15 patients, minimal change disease(MCD) was 14, focal segmental glomerulosclerosis (FSGS) was 8, membranoproliferative glomerulonephritis (MPGN) was 3, lupus nephritis(LN) was 3, poststreptococcal glomerulonephritis(PSGN) was 3 and membranous glomerulonephritis(MGN) was 2. 3) In 26 patients (54%) with nephrotic-range proteinuria, Grade 2 or higher renal uptake was observed in 9 (75%) of MCD, 5(100%) of FSGS, 2(100%) of LN and 3(75%) of IgAN. 4) In comparision nephrotics with non-nephrotics at biopsy, renal Ga-67 uptake in who patients had nephrotic-range proteinuria was correlated with clinical severity determined by serum albumin, serum total cholesterol and 24 hours urine protein excretion. CONCLUSIONS: Renal Ga-67 scintigraphy may be able to be a predictor in the assessment for severity of nephrotic syndrome.

The World Health Organization declared that a new strain of novel swine-origin influenza A (H1N1) virus was responsible for the pandemic infection in June 2009. We report a case of encephalitis diagnosed as the H1N1 virus infection. We describe a 17-year-old patient who had a seizure attack, diagnosed with a H1N1 virus infection via real time reverse-transcriptase polymerase chain reaction (RT-PCR). The H1N1 virus infection can be causative of the encephalitis, as with other influenza virus infections. Careful monitoring is essential for reducing complications.

We evaluated the gender differences in the relation of baseline serum gamma-glutamyltransferase (GGT) levels to blood pressure (BP) change during 4 yr. 4,025 normotensive subjects (1,945 men and 2,080 women) who aged 40-69 yr at baseline participated in the Ansung-Ansan cohort of the Korean Genome Epidemiology Study were included. The associations of GGT with baseline BP or 4-yr change of BP were evaluated. GGT levels were associated with systolic blood pressure (SBP) and diastolic blood pressure (DBP) at baseline after adjusting for age, body mass index (BMI), HDL-cholesterol, triglyceride, C-reactive protein (CRP), current smoking status and alcohol intake (SBP, beta=1.28, P<0.001; DBP, beta=1.41, P<0.001). GGT levels were also associated with 4-yr change in BP after adjusting for age, BMI, HDL-cholesterol, triglyceride, CRP, current smoking status, alcohol intake and SBP (SBP, beta=1.08, P=0.001; DBP, beta=0.64, P=0.003). This association was statistically significant in men (SBP, beta=1.82, P<0.001; DBP, beta=1.05, P=0.001), but not in women (SBP, beta=0.38, P=0.466; DBP, beta=-0.37, P=0.304). Remarkably, this association between GGT and BP was significant in men at 40-49 yr of age. In summary, we found positive associations between GGT levels at baseline and the change of BP. The relation of GGT level and the change of BP was only significant in men, not in women, which warrants further studies to elucidate the biologic mechanisms.
