Case ReportsGenetic and clinical characteristics of korean patients with isolated hypoparathyroidism: from the Korean hypopara registry study.
Isolated hypoparathyroidism (IH) shows heterogeneous phenotypes and can be caused by defects in a variety of genes. The goal of our study was to determine the clinical features and to analyze gene mutations in a large cohort of Korean patients with sporadic or familial IH. We recruited 23 patients. ⋯ Besides, heterozygous gain-of-function mutations in the CASR gene were found in other subjects; D410E and P221L. We also found one single nucleotide polymorphism (SNP) in the prepro-PTH gene, five SNPs in the CASR gene, and four SNPs in the GCMB gene. The current study represents a variety of biochemical phenotypes in IH patients with the molecular genetic diagnosis of IH.

Epidemiology of hemorrhagic fever with renal syndrome in Korea, 2001-2010.
This study describes the epidemiology of hemorrhagic fever with renal syndrome (HFRS) in the past 10 yr (2001-2010) in Korea. During this period, a total of 3,953 HFRS patients and an average prevalence rate of 0.81 per 100,000 population were recorded, with a total of 40 fatal cases, corresponding to a case fatality rate of 1.01%. More HFRS cases were found in men than in women (57% vs 43%), and a higher prevalence rate of HFRS was observed in patients older than 40 yr (82.1%). ⋯ More HFRS cases occurred in the western part than in the eastern part of Korea (68.9% vs 31.1%). The incidence of HFRS was significantly higher (P < 0.001) in rural areas than in urban areas (80.3% vs 19.7%). HFRS still occurs commonly among men, in autumn, and in western rural area of Korea.

Chronic kidney disease, hemodynamic instability, and endoscopic high-risk appearance are associated with 30-day rebleeding in patients with non-variceal upper gastrointestinal bleeding.
The results of studies that evaluated predictive factors for rebleeding in non-variceal upper gastrointestinal bleeding are inconsistent. The aim of this study was to investigate predictive factors for 30-day rebleeding in these patients. A consecutive 312 patients presenting symptoms and signs of gastrointestinal bleeding were enrolled in this prospective, observational study. ⋯ However, neither Rockall nor Blatchford scores showed statistically significant relationships with 30-day rebleeding in a multivariate analysis. CKD, hemodynamic instability during hospitalization, and an endoscopic high-risk appearance are significantly independent predictors of 30-day rebleeding in patients with non-variceal upper gastrointestinal bleeding. These factors may be useful for clinical management of such patients.

Case ReportsA case of extrinsic compression of the left main coronary artery secondary to pulmonary artery dilatation.
Extrinsic compression of the left main coronary artery (LMCA) secondary to pulmonary artery dilatation is a rare syndrome. Most cases of pulmonary artery hypertension but no atherosclerotic risk factors rarely undergo coronary angiography, and hence, diagnoses are seldom made and proper management is often delayed in these patients. ⋯ Follow-up coronary angiography showed patent stent in the LMCA in the proximity of the dilated main pulmonary artery. This case reminds us that coronary angiography and percutaneous coronary intervention should be considered in pulmonary hypertension patients presenting with angina or left ventricular dysfunction.

Patients with persistent new-onset diabetes after transplantation have greater weight gain after kidney transplantation.
The purpose of the present study was to evaluate the difference in BMI pattern between patients with persistent new-onset diabetes after transplantation (P-NODAT) and without new-onset diabetes after transplantation (N-NODAT) in a retrospective matched case-control (1:3) analysis. Thirty-six patients who developed P-NODAT were identified among 186 adult renal transplant recipients with no evidence of pretransplant diabetes mellitus who underwent kidney transplantation from September 1997 to March 2008 and were treated with a triple regimen including tacrolimus. The controls were selected to match the patients for pretransplant BMI, age at transplantation (± 5 yr), and date of transplantation (± 12 months). ⋯ The mixed-model analysis showed that patients with P-NODAT exhibited a faster increase in BMI. P-NODAT is associated with posttransplant weight gain. The risk of P-NODAT should be considered in patients with rapid weight gain after transplantation.
