A large osteochondral fragment trapped in the posterolateral compartment of a knee was removed from a posteromedial portal through the trans-septal portal and fixed on an osteochondral defect of the lateral femoral condyle in a 16. year-old boy. When a free body in the posterolateral compartment is so large that enlargement of the portal site is required for removal, doing so from a posteromedial portal is safer and easier than from a posterolateral portal. © 2013 Elsevier B.V.

We tested the hypothesis that uric acid levels predict new-onset hypertension in the Japanese general population. Normotensive individuals who visited our hospital for a yearly health checkup (n=8157, men=61.0% and age=50.7±12.2 years) were enrolled in the present study. After baseline evaluation, participants were followed up for a median of 48.3 months (range 4.9-101.0 months), with the endpoint being the development of hypertension, defined as systolic blood pressure (BP) ≥140 mm Hg, diastolic BP ≥90 mm Hg or the use of antihypertensive medication. The impact of uric acid and other cardiovascular risk factors at baseline on future BP and development of hypertension was assessed. During follow-up, 19.0% of women (n=605) and 29.5% of men (n=1 469) participants developed hypertension. Incident hypertension was increased across the quartiles for baseline uric acid levels (P<0.0001), and multivariate Cox proportional hazards analysis revealed a significant and independent association between the uric acid level and the onset of hypertension in both men and women participants (P<0.05). Furthermore, uric acid was independently and positively correlated with future BP (P<0.05). Thus, uric acid is an independent predictor of new-onset hypertension in both women and men. © 2014 Macmillan Publishers Limited. Source

The present study investigated factors that modify or affect arterial stiffness as assessed by brachial-ankle pulse wave velocity (baPWV) in the general population. Subjects had previously participated in a physical checkup program (n=911), and baPWV and urinary albumin and sodium excretion were also measured. Urine albumin was expressed as the ratio of urine albumin to urine creatinine. Individual salt intake was assessed by estimating 24-h urinary salt excretion and expressed as the ratio of estimated salt intake to body weight. The mean blood pressure and baPWV were 127.1±15.2/77.0±9.5 mm Hg and 15.9±3.3 m s-1, respectively. Univariate analysis demonstrated that baPWV correlated with various factors including age, blood pressure, electrocardiogram voltage (SV 1 +RV 5), urine albumin and salt intake. Multivariate regression analysis revealed that electrocardiogram voltage (P<0.001), systolic blood pressure (P<0.0001), urine albumin (P<0.001) and salt intake (P<0.001), independently correlated with baPWV after adjustment for other possible factors. Similar results were obtained for participants not taking any medication. These results suggest that the baPWV value is independently associated with individual salt intake and cardiac and renal damage, and could be a useful procedure for identifying individuals with concealed risk of cardiovascular disease. © 2012 Macmillan Publishers Limited.

Central blood pressure is more closely associated with cardiovascular events and target organ damage than peripheral blood pressure measured over the brachium using a conventional method. This study was designed to investigate the distribution of central systolic blood pressure values estimated by Omron HEM-9000AI in the Japanese general population. A cross-sectional study were performed in 10 756 subjects without overt cardiovascular disease (male=6574; mean age 55.3±12.5 years, range 20-91 years). Of these, 7348 subjects received no antihypertensive, antidiabetic or lipid-lowering drug treatment, and were used for the present analysis. Estimated central systolic blood pressure was higher than brachial systolic blood pressure and was significantly correlated with age and brachial blood pressure. The central systolic blood pressure values obtained from subjects without cardiovascular risk factors other than hypertension were 125.8±37.2 (mean±2 s.d., n=3760) mm Hg. The values obtained from subjects with no cardiovascular risk factors were 112.6±19.2 (n=1975) mm Hg for optimal and 129.2±14.9 mm Hg for normal brachial blood pressure categories (n=697). This study is the first to show the distribution of central systolic blood pressure values estimated using the Omron HEM-9000AI, marking an important step toward implementing the clinical use of central blood pressure in the diagnosis and management of hypertension. © 2013 The Japanese Society of Hypertension All rights reserved.

Background: B-type natriuretic peptide (BNP) and N-terminal proBNP (NT-proBNP) are useful biomarkers in the management of heart failure. Both peptides are secreted into the circulation after cleavage of their precursor proBNP and excreted from the kidney in the active form or as metabolites. We investigated effects of kidney function on the levels and association of these peptides. Materials and methods: Plasma concentrations of BNP and serum concentrations of NT-proBNP were measured in 229 outpatients of our cardiology department (male/female = 138/91, mean age= 68 years) and 53 hospital outpatients on chronic haemodialysis (30/23, 68 years). Kidney function in nondialysed patients was assessed by estimated glomerular filtration rate (eGFR; mL/min/1·73 m2) and categorised across five stages. Effects of kidney function on BNP, NT-proBNP and their relationship were investigated. Results: Deterioration in kidney function increased BNP and NT-proBNP levels, as well as the NT-proBNP/BNP ratio, and these values were highest in patients on haemodialysis. The eGFR inversely correlated with BNP (r = -0·472), NT-proBNP (r = -0·579), and the NT-proBNP/BNP ratio (r = -0·454, all P < 0·0001). A significant correlation was observed between BNP and NT-proBNP at all stages of kidney function including patients on haemodialysis, but the correlation was significantly affected by kidney function. Conclusions: Although circulating levels of both BNP and NT-proBNP increased with deteriorating kidney function, the impact of kidney function on NT-proBNP was much more pronounced than that on BNP. Kidney function should be taken into account when interpreting data on BNP, NT-proBNP and their relationship. © 2013 Stichting European Society for Clinical Investigation Journal Foundation. Source
