Objectives: We examined the efficacy of tolvaptan, an orally effective nonpeptide vasopressin V2 receptor antagonist, in a Japanese clinical study in patients with intractable ascites and/or lower limb edema associated with decompensated liver cirrhosis. Methods: Tolvaptan was orally administrated at titrated doses of 15, 30, and 60 mg once daily after breakfast for 3 days at each dose to 18 liver cirrhosis patients with persistent ascites and/or lower limb edema despite receiving oral furosemide at 40 mg/day or higher. Results: Decreased body weight and abdominal circumference and improvement of ascites and edema were observed following tolvaptan administration beginning from 15 mg. Composite ascites/edema improvement rate was 88.2% at individual maximum doses and 64.7, 80.0, and 90.9%, respectively, after 3-day administration at 15, 30, and 60 mg. Changes in body weight after 3-day administration at 15, 30, and 60 mg were -1.6 ± 0.9, -2.6 ± 1.2, and -3.4 ± 2.1 kg (mean ± SD), respectively, and decreases of 1 kg or more were seen from day 2 (24 h after first dosing). Changes in abdominal circumference ranged from -2.8 to -6.0 cm. Cumulative 24-h urine volumes after 3-day administration at 15, 30, and 60 mg were, respectively, 3240.3 ± 1014.5, 3943.3 ± 1060.6, and 4537.4 ± 1621.3 mL/day (mean ± SD). Urine osmolarity was markedly decreased and remained decreased until the end of treatment. Conclusion: Tolvaptan dose-dependently decreased body weight and abdominal circumference and improved ascites and edema beginning from 15 mg, demonstrating a potent aquaretic effect. © 2010 Springer.

Mammary analogue secretory carcinoma (MASC) with an ETS variant gene 6 (ETV6)-neurotrophic tyrosine kinase receptor type 3 (NTRK3) translocation is a newly described type of salivary gland cancer. It is known that overexpression of signal transducer and activator of transcription 5a (STAT5a) occurs in secretory carcinoma of the breast and MASC, and STAT5a expression may be related to the ETV6-NTRK3 translocation. It was hypothesized that phosphorylated signal transducer and activator of transcription 5 (p-STAT5) might be specifically expressed in MASC of the salivary gland.The expression of p-STAT5 and mammaglobin (MMG) was examined with immunohistochemistry (IHC)/immunocytochemistry (ICC) in tissue sections from 58 salivary gland cancers (8 MASCs and 50 other salivary gland cancers) and in cytological smears from 17 salivary gland cancers (7 MASCs with paired histologic samples and 10 other salivary gland cancers).p-STAT5 IHC was clearly increased in MASC versus normal salivary gland tissue and other salivary gland cancers. p-STAT5 expression was found in 7 of 8 MASCs (87.5%) and in none of the 50 other salivary gland cancers (0%) by IHC. On cytology, p-STAT5 expression was found in all cases of MASC (7 of 7 or 100%) but in none of the 10 other salivary gland cancers (0%) by ICC. The expression rate of MMG by histology and cytology was higher than that of p-STAT5 in the other salivary gland cancers.p-STAT5 might be useful as a detection marker of MASC in the differential diagnosis of salivary gland cancers, and initial screening with p-STAT5 IHC/ICC, combined with auxiliary fluorescence in situ hybridization confirmation, is a reliable, economical approach to identifying MASC of the salivary gland.

Background: Diabetes mellitus is frequently seen in hepatitis C patients and is often treated with antidiabetic agents that increase serum insulin levels. Because insulin is a growth-promoting hormone, antidiabetic agents could pose a risk for hepatocellular carcinoma (HCC). Aim: The aim of this study was to investigate an association between antidiabetic therapies and the incidence of HCC in hepatitis C patients with diabetes mellitus. Methods: A nested case-control study was conducted. Participants were recruited from a cohort study, in which patients with hepatitis C were consecutively registered. Participants were assigned to an HCC group (n=138) or a non-HCC group (n=103). To identify independent factors, variables including use of antidiabetic agents were analysed by logistic regression analysis. Results: Besides ageing, being male, cirrhosis and hypoalbuminaemia, use of exogenous insulin and a second-generation sulphonylurea were significant independent factors associated with an incidence of HCC [odds ratio (OR) 2.969, 95% confidence interval (CI) 1.293-6.819, P<0.0103 and OR 6.831, 95% CI 1.954-23.881, P<0.0026 respectively). In stratified analyses, the impact of these antidiabetic agents was more evident in patients who were non-cirrhotic than in those who were cirrhotic. Conclusions: Exogenous insulin and a second-generation sulphonylurea were independent variables associated with an incidence of HCC in hepatitis C patients with diabetes mellitus. This association was evident in patients who were non-cirrhotic. To verify a causal relationship between these antidiabetic agents and the development of HCC, a prospective cohort study is required. © 2009 John Wiley & Sons A/S.

We studied the efficacy of sitagliptin in type 2 diabetic patients of our outpatient clinics. Since December in 2009, 164 patients have been treated by sitagliptin for their management of diabetes. HbA1c decreased by 0.8% in all patients without any change in mean body weight after 3 months. However, actually HbA1c did not decrease in 30 patients, and more than half of patients showed weight gain to some extent. Patients were classified according to the reduction of HbA1c and analyzed based on this category. Baseline characters such as age, gender, duration of diabetes, BMI, concomitantly used oral hypoglycemic agents and the score for life-style assessment were not related to glucose-lowering effect of sitagliptin. Ninety eight patients whose HbA1c had decreased after 3 months were further followed-up for another 3 months. Among them 45 patients showed some relapsing of HbA1c after 6 months, and they were compared with 53 patients without relapsing. More cases had been switched from α-glucosidase inhibitor (α-GI) and the score for life-style assessment was lower in relapsing patients compared to those in patients without relapsing. In conclusion, clinicians should keep the fact in mind that the individual variation of glucose-lowering effects and the possibility of relapsing exist during sitagliptin treatment, and that concern about life-style is still a quite important issue to prevent weight gain and the relapsing of blood glucose control. © The Japan Endocrine Society.

Background: Guidelines recommend chronic obstructive pulmonary disease (COPD) assessment tests (CATs) for evaluation of symptoms and management risks. To investigate whether CAT can predict moderate or severe exacerbations in Japanese COPD patients, a single-blinded prospective study was performed. Methods: A 123 Japanese COPD patients were classified into high-CAT (n=64) and low-CAT (n=59) groups. The frequencies and periods of moderate or severe exacerbation and hospitalization were compared between the two groups. Multivariate logistic regression analysis was performed to investigate whether CAT could predict exacerbations. A receiver operating characteristic (ROC) curve analysis was employed to find an appropriate CAT score for exacerbation. Results: The high-CAT group was significantly older, had a lower body mass index, and had a lower airflow obstruction as compared to the low CAT group. The frequency of moderate or severe exacerbation (1.3±1.3 events per patient per year, p<0.0001) and hospitalizations (0.2±0.4, p=0.0202) in the high-CAT group was significantly higher than in the low-CAT group (0.4±0.7 and 0.0±0.1, respectively). Multivariate logistic regression analysis showed that both high CAT score and low airflow obstruction were independently predictive of frequent moderate or severe COPD exacerbation. ROC analysis showed that the best cut-off CAT score for moderate or severe COPD exacerbation was 8 points. Conclusion: Our present results indicate that COPD Japanese patients showing high CAT scores have a poor prognosis, and that the CAT score is able to predict exacerbation in Japanese COPD. © 2014 The Japanese Respiratory Society.

Background: The prognosis of Japanese patients with COPD who suffer repeated exacerbations is unclear, although Westerners with such episodes have a poor prognosis. Materials and methods: We conducted a 1-year prospective observational trial involving 90 Japanese patients with COPD: 58 nonexacerbators, 12 infrequent exacerbators, and 20 frequent exacerbators classified on the basis of exacerbation frequency (zero, one, and two or more exacerbations/year), respectively, during the previous year were observed prospectively for 1 year. The characteristics of frequent exacerbators, the frequency of exacerbation, and the period until the first event were then compared among the groups. Results: A total of 78 patients completed the study. Frequent exacerbators had a significantly higher risk of frequent exacerbation in the following year than the case for nonexacerbators (odds ratio [95% confidence interval] 2.94 [1.21-7.17], P=0.0340), but not in comparison with infrequent exacerbators (1.51 [0.49-4.63], P>0.05). The mean annual frequency of exacerbations in the following year was significantly (P=0.0020) higher in the frequent exacerbators (1.4 exacerbations/year) than in the nonexacerbators (0.4), but not in the infrequent exacerbators (0.9, P>0.05). The mean period until the first exacerbation was significantly shorter in the frequent exacerbators than in the infrequent or nonexacerbators (P=0.0012). Independent risk factors for future frequent exacerbation included the presence of gastroesophageal reflux disease, more severe airflow obstruction, and use of inhaled corticosteroids. Conclusion: Our present results indicate that Japanese COPD patients suffering frequent exacerbation have a poor prognosis. The characteristics of Japanese and Western COPD patients suffering frequent exacerbation are similar. © 2016 Tomioka et al.

Controlling blood pressure is essential for prevention of events after acute aortic dissection (AAD). However, in some instances a cardiac event occurs despite controlled blood pressure, and its prediction is difficult. We continuously monitored C-reactive protein (CRP) in patients receiving medical treatment for AAD and retrospectively examined the utility of CRP measurement for prediction of in-hospital events. Five hundred and eight patients were diagnosed as having AAD between 1993 and 2009, 240 of whom underwent antihypertensive medical therapy. These subjects were 156 males and 84 females, average age 67.4 years, with 68 cases of Stanford type A and 172 cases of Stanford type B. C-reactive protein was measured in all patients daily until a peak; subsequently, CRP was measured 2-3 times per week following the peak until discharge. In the event-free group CRP demonstrated a peak on the 4th day after the onset (average 13.7 mg/dl), then gradually decreased to an average of 4.6 mg/dl 4 weeks later, displaying a "gradual decay" pattern. Despite controlled systolic arterial pressure of approximately 120 mmHg, 7 of 68 Stanford A cases (10.3 %) and 8 of 172 Stanford B cases (4.7 %) developed cardiovascular events. The group characterized by events exhibited a CRP pattern distinct from that of the event-free group, i.e., prolonged elevation and/or re-elevation. We demonstrated that the CRP pattern could provide information regarding prediction of cardiovascular events. Prolonged elevation or re-elevation of CRP may indicate the necessity of (1) application of computed tomography or magnetic resonance imaging, (2) more rigorous blood pressure management, or (3) early surgical intervention. © 2012 Springer.

There is controversy about the treatment for unstable full radial posterior lateral meniscus tears, particularly that involving the posterior root. Some surgeons have advocated repairing these types of meniscus tears using various techniques, but their methods are somewhat technical. We developed the technique for an all-inside repair for full radial posterior lateral meniscus tears using the Meniscal Viper (Arthrex, Naples, FL). A doubled thread is passed through 1 edge of the radial tear by the Meniscal Viper and is kept in place without tying the knot. The Meniscal Viper is used again to set a new thread, repeating the same procedure to another edge of the tear. At this step, 2 doubled threads are passed through each stump of the tear, and both a loop end and 2 free ends of each thread are located outside of the joint. Then, 2 doubled threads pass the third thread into its own loop, pulling it out. Finally, the third thread becomes the mattress suture over the radial tear site and is fastened by sliding knot techniques. This procedure makes it easy to strictly, smoothly, and less invasively shorten the gap by drawing each stump of the meniscus in the direction of the circumference.

Double-bundle anterior cruciate ligament (ACL) reconstruction using hamstring tendon grafts is a standard procedure for ACL injury. However, its clinical effectiveness is not always satisfactory. One cause of this was problems with the graft-tunnel healing of the posterolateral bundle (PLB) on the femur. To solve this problem, we devised a new anatomic ACL reconstruction technique to improve the graft-tunnel healing of the femoral PLB by using a single-bundle with one bone tunnel on the femoral side and a double-bundle on the tibial side. We have performed 40 procedures with excellent results and no cases of intra- or postoperative complication. This procedure can help improve the graft-tunnel healing around the femoral bone tunnel aperture for the PLB.

The aim of this study was to evaluate the efficacy of daclatasvir plus asunaprevir therapy in patients infected with hepatitis C virus and determine its relevance to resistant variants.A total of 629 consecutive patients infected with hepatitis C virus genotype 1 were assessed. Daclatasvir (60 mg/day) plus asunaprevir (200 mg/day) was given for 24 weeks. The virological responses and resistance-associated substitutions of hepatitis C virus mutants were examined by the direct sequence and cycleave methods were evaluated.Overall, 89.4% (555/621) of patients exhibited a sustained virological response (SVR). The SVR rates in the patients with wild type, mixed, and mutant type Y93 by direct sequencing were 92.5% (520/562), 70.3% (26/37), and 42.9% (9/21), respectively. The SVR rates in the patients with 100%, 90%, 80%-30%, and 20%-0% Y93 wild by the cycleave method were 93.4% (456/488), 88.2%(30/34), 56.0%(14/25), and 36.8%(7/19), respectively. In contrast, the SVR rates for the wild type and mixed/mutant type L31 by direct sequencing were 90.2% (534/592) and 72.4% (21/29), respectively. In the multivariate analyses, the wild type Y93, no history of simeprevir therapy, the wild type L31, and low HCV RNA level were independent factors of SVR.NS5A resistance-associated substitutions, especially Y93H, were major factors predicting the SVR. Although direct sequencing can predict the SVR rate, the cycleave method is considered to be more useful for predicting the SVR when used in combination.
