Kawasaki disease is an acute vasculitis of infancy and early childhood characterized by high fever, rash, mucositis, lymphadenopathy and coronary artery damage. The failure to indentify a causative organism using convetional culture and serological techniques, and the lack of response to antibiotics indicate that the disorder is probably not due to any known bacterial or viral pathogens. During the acute phase of the disease, the alterations of T and B cell functions, changes of cytokine and immunoglobulin levels have been reported. This study was performed to investigate the changes of immunoglobulins levels in patients with Kawasaki disease. IgG, IgA, IgM and IgG subclasses were measured using immunoprecipitation and EIA in the sera of patients with Kawasaki disease. The results were as follows: 1) Acute phase reactants such as CRP and ESR were significantly increased in Kawasaki patients compared to those in control patients(p<0.01). 2) Serum IgG levels in Kawasaki disease were markedly increased than those in control patients, while serum IgA and IgM levels showed no significant changes (P: No Significance). 3) IgG1 and IgG4 were predominantly increased increased in the sera of Kawasaki patients, while IgG2 and IgG3 were not significantly increased (P: No Significance). With these results, unidentified infectious organism with abnormal immune response could be suggested as an etiologic factor of Kawasaki disease.

Metabolic acidosis (MA) is associated with increased proteolysis, increased osteoclast activity and blunted cardiac muscle response, but the effect of MA on various clinic al parameters in CAPD patients is not well known. To evaluate the effects of MA on serum albumin level and other nutritional parameters in CAPD patients, we studied 106 CAPD patients retrospectively who have had monthly biochemical measurement and urea kinetic studies every 6 months for more than 2 years. The patients were divided into three groups according to their mean total CO2 (tCO2) level of the 2-year follow-up (Group l; mean tCO2 < 22mM/L, Group ll; 22mM/L < or = mean tCO2 < 26mM/L, and Group lll; mean tCO2 > or = 26mM/L), and the clinical, biochemical, and urea kinetic data were compared among the three groups. 1)The mean age of the subjects was 46.9+/-12.2 years with a sex ratio of 1.2:1, the mean CAPD duration 28.3+/-21.8 months, mean body weight (Bwt) 59.0+/-8.9kg, %Bwt/IBW 104.1+/-11.5%, %LBM/Bwt 75.5+/-11.1% and well-nourished patients by subjective global assessment (SGA) were 65%. 2)The mean BUN, creatinine, total protein and albumin of all patients were 55.6+/-13.6mg/dL, 12.3+/-3.5mg/dL, 6.6+/-0.7g/dL and 4.0+/-0.4g/dL, respectively. In urea kinetic study, the mean NPCR, weekly Kt/ Vurea, SCCr and RRF were 0.96+/-0.16g/kg/day, 2.02+/-0.37, 63.7+/-18.4L/week/1.73m2, and 0.99+/-1.32ml/ min, respectively. 3)The mean age was significantly higher in group l (51.0+/-10.8) than those of group ll (47.0+/-12.4) and lll (42.6+/-11.4) (P<0.05). %Bwt/IBW of group l (114.4+/-15.8%) was also significantly higher than those of group ll (104.6+/-12.6%) and lll (103.5+/-13.7 %) (P<0.05), but there were no significant differences in sex ratio, CAPD duration, %LBM/Bwt, and SGA among the three groups. 4)The mean tCO2 in group l, group ll, and group lll were 20.6+/-1.2mM/L, 23.9+/-1.1mM/L, and 27.3+/-0.8mM/L, respectively. Compared to group lll, group l had significantly higher BUN (61.1+/-14.3 vs. 46.1+/-7.2mg/dL, P<0.05) and serum albumin (4.04+/-0.31 vs. 3.75+/-0.39g/dL, P<0.05), in spite of comparable dialysis dose and albumin loss into dialysate. 5)NPCR (1.02+/-0.21g/kg/day vs. 0.88+/-0.14g/kg/ day, P<0.05) and ultrafiltration volume (1.4+/-0.4 vs. 1.0+/-0.3, P<0.05) were significantly higher in group l than those of group lll. But there were no significant differences in Kt/Vurea, SCCr, RRF, and 24-hour dialysate loss of protein/albumin among the three groups. 6)No differences were observed among the three groups in the changes of body weight, %Bwt/IBW, %LBM/Bwt, BUN, albumin, NPCR, and RRF from the baseline values after the 2-year follow-up. 7)There were significant inverse correlations between the mean tCO2 level and NPCR (r=-0.33, P<0.001), %Bwt/IBW (r=-0.32, P<0.001), RRF (r=-0.29, P<0.005), and serum albumin level (r=-0.24, P<0.05). But, creatinine, %LBM/Bwt, and Kt/Vurea did not show any correlation with the mean tCO2 level. 8)Using stepwise multiple regression analysis, NPCR (beta=-0.3491, P<0.001), %Bwt/IBW (beta=-0.046, P<0.001), and ultrafiltration volume (beta=-0.0012, P< 0.005) were independent factors affecting the mean tCO2 level. In conclusion, low total CO2 level in long-term CAPD patients may reflect increased protein intake and mild to moderate degree of metabolic acidosis may not affect the nutritional status of well-dialyzed CAPD patients.

Since coronary arteriovenous fistula(CAVF) was first reported by Krause in 1865, more than 400 cases have been reported. It is relatively rare disease and originates more commonly in the right than in the left coronary artery. We report a case of CAVF between right coronary artery and right ventricular inflow tract with significant left to right shunt in a 34-year old female who was admitted for the cardiomegaly on routine chest X-Ray. It was detected by transthoracic and transesophageal echocardiography, and confirmed by cardiac catheterization and coronary angiography. The opening of the fistula draining into the right ventricle was obliterated with sutures. There was no significant shunt in postoperative cardiac catheterization and coronary angiography.

The angiotensin-converting enzyme (ACE) gene DD homozygote has been suggested to be a significant risk factor for the progression of diabetic nephropathy. We analyzed clinical parameters and ACE genotype distribution between type 2 diabetic patients at the extremes of renal risk, i.e. an end-stage renal failure (ESRF) group (n = 103, group 1) who were on dialysis therapy due to progression of diabetic nephropathy, and a no progression group (n = 88, group 2) who had maintained normal renal function and normoalbuminuria for more than 15 years. There were no significant differences in age, sex, body mass index, HbA1c level, or lipid profiles between the two groups (p > 0.05). Group 1 had a significantly higher prevalence of hypertension [group 1: 82.5% (85/103) vs. group 2: 50.0% (44/88), p < 0.05] and diabetic retinopathy [group 1: 103/103 (100%) vs. group 2: 28/88 (31.8%), p < 0.05] than group 2. Daily urinary albumin excretion was also higher in group 1 than in group 2 [group 1: 2873 +/- 2176 mg/day vs. 12 +/- 7 g/day, p < 0.05]. The frequencies of the DD, ID, and II genotypes of the ACE gene in group 1 and group 2 were 26.2%, 47.6%, and 26.2%, and 7.9%, 57.9%, and 34.2%, respectively. The ACE genotype frequencies between the two groups were significantly different according to a chi-square test with Bonferroni's correction (p = 0.004). The presence of the DD genotype increased the risk of ESRF 4.286-fold compared to the II genotype [odds ratio 4.286, 95% CI 1.60- 11.42, p = 0.005]. The frequency of the D-allele was higher in both male and female patients in group 1 compared to group 2, but reached statistical significance only in males [male, group 1: 50.8% vs. group 2: 35.0%, p = 0.018, female, group 1: 48.8% vs. group 2: 39.5%, p = 0.231]. This study, although limited by sample size, showed that type 2 diabetic ESRF patients more frequently expressed the DD genotype. These findings may substantiate the previously noted relationship between the ACE DD genotype and the progression of diabetic nephropathy in Korean type 2 diabetic patients.

BACKGROUND: Recent restriction enclonuclease analysis studies hsve revealed that MCV DNA can be classified into two major types, designated MCV-1 and MCV-2, by th:ir restriction enzyme cleavsge patterns. In earlier reports of MCV DNA analysis, MCV-2 was the main virus type found in genital lesions. However many recent studies cienied the relationship between virus type and anatomical distribution. OBJECTIVE: The purpose of this study was to examine the ratio of MCV-l to MCV-2 in Korean isolates of MCV DNA and the relationship between MCV subtypes and with clinical features such as anatomical location, age, sex, numiber of lesions, and atopic dermatitis. METHODS: MCV DNA extrated from 112 cases of Korean patients waa examined by restriction endonuclease analysis using Brtm HI. RESULTS: 1. MCV-1 was found in 108 of 112 (96.4%) patients and MCV-2 in of 112 (3.6%) patients. The ratio of MCV-1 to MCV-2 wss 28:1. 2. There was no significant ciprrelation between MCV subtypes and the age, sex, number of lesions, atopic dermatitis, and anatoimic loction. 3. Lesions induced by MCV-1 MCV-2 were indistinguishable on the brsis of size and form. CONCLUSION: This study showis that the ratio of MCV-1 to MCV-2 was 28:1 in Korean molluscum contagiosum patients and there was no relationship between MCV subtyies and lesional morphology or snatomical distribution.

PURPOSE: The conventional trocar and cannula method in peritoneal dialysis (PD) catheter insertion has its limitation in clinical setting. The aim of this study was to compare a modified method for percutaneous PD catheter insertion with the conventional method, and demonstrate advantages of the modified method. MATERIALS AND METHODS: Patients at a single center who had percutaneous PD catheters inserted by nephrologists from January 2006 until September 2012, using either a modified method (group M) or the conventional trocar and cannula method (group C), were retrospectively analyzed, in terms of baseline characteristics, complications experienced up to 3 months after the procedure, and the suitability of the procedure for patients. RESULTS: Group M included 82 subjects, while group C included 66 cases. The overall early complication rate in group M (1.2%) was significantly lower than that in group C (19.7%) (p<0.001). The catheter revision rate during timeframe for early complications was significantly lower in group M (0%) than in group C (6.1%) (p=0.024). When comparing Procedure time (1 h 3 min+/-16 min vs. 1 h 36 min+/-19 min, p<0.01), immediate post-procedural pain (2.43+/-1.80 vs. 3.14+/-2.07, p<0.05), and post-procedure days until ambulation (3.95+/-1.13 days vs. 6.17+/-1.34 days, p<0.01), group M was significantly lower than group C. There was no significant difference in total hospitalization period (14.71+/-7.05 days vs. 13.86+/-3.7 days). CONCLUSION: Our modified PD catheter insertion method shows its advantages in early complication rate, early complications revision rate, and the patients' conveniences.

In this study, almost complete genomic sequences of PPV1 and PPV4 circulating in commercial pig farms in South Korea were obtained and analyzed. Important mutations that may be precursors to host changes, such as premature stop codons of PPV1 and frameshift mutations of PPV4, were observed in these sequences. A 27a-like strain of PPV1, known to show a lack of cross-neutralization against existing commercial vaccine strains, was identified by phylogenetic analysis. Given the active genetic evolution, the additional precursors to host changes and emerging new genotypes of PPVs need to be monitored through continuous sampling and genetic analysis.

Ruptured aneurysm of sinus of Valsalva is an uncommon congenital lesion, which was first reported in 1840 by Thurman. Its incidence is representing up to 3.5% of patients undergoing congenital heart disease surgery. Predominant symptoms are dyspnea, palpitation, and chest pain, present above the half. An early diagnosis is helpful because of the favorable surgical prognosis. Echocardiography remains useful in detecting abnormalities, and provides important information prior to cardiac catheterization and surgery. Cardiac catheterization and angiography are necessary for diagnosis of receiving chamber and associated lesions such as ventricular septal defect, aortic regurgitation, and other congenital abnormalities. The effective treatment is surgery. Without operation, cause of death are heart failure or bacterial endocarditis. We report two cases of asymptomatic ruptured aneurysm of sinus of Valsalva, confirmed by transesophageal echocardiography, and cardiac catheterization. The corrective surgery was performed without complication.

PURPOSE: Smoking reportedly exerts deleterious effects on renal function; however, its effects on histology have not been clarified in patients with IgA nephropathy (IgAN). MATERIALS AND METHODS: Renal histology was evaluated in a cohort of 397 patients diagnosed with IgAN according to smoking status and dose in relation to renal function. RESULTS: Among the study cohort, which was predominantly male (88.5%), 52 patients (13%) were current smokers. These current smokers demonstrated more frequent hypertension and higher serum creatinine levels than non/ex-smokers at the time of diagnosis, which was apparent with increased smoking dose. The percentages of global glomerulosclerosis and arteriolar hyalinosis increased with increased smoking dose, whereas tubulointerstitial fibrosis or arterial intimal thickening did not. Glomerular mesangial alpha-smooth muscle actin expression were similar between current and non/ex-smokers matched for age, gender, hypertension, and histologic severity, although the number of glomerular CD68+ cells was significantly fewer in smokers. Initial serum creatinine level, estimated glomerular filtration rate (eGFR), and global glomerulosclerosis were found to be risk factors of serum creatinine doubling in both smokers and non/ex-smokers by univariate analysis during a mean follow-up of 3.8 years. CONCLUSION: In addition to dose dependent renal functional decline and hypertension, smoking contributes to renal disease progression by eliciting microvascular injury in IgAN patients.
