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.

Summary: 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. © 2015, Kurume University School of Medicine. All rights reserved. Source

BACKGROUND 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. METHODS 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). RESULTS 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. CONCLUSIONS 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. © 2015 American Cancer Society.

Background and Aim: Kupffer cell (KC) function and CD14 expression contributes to pathogenesis of non-alcoholic steatohepatitis (NASH). However, these relationships remain unclear. We investigated the relationship of KC function with superparamagnetic iron oxide-enhanced magnetic resonance imaging (SPIO-MRI), histopathological severity of NASH, and number of CD14-positive KCs in NASH. Methods: This retrospective study included 32 patients (24 with NASH and eight with simple steatosis) who had previously undergone SPIO-MRI with T2-weighted gradient-recalled echo sequence. All subjects were diagnosed pathologically and were evaluated for necroinflammation grade, fibrosis stage, and number of CD14-positive KCs. Patients with NASH and simple steatosis were compared by using the Mann-Whitney test to determine differences in percent reduction of liver-to-muscle signal intensity ratio (reduction-%LMR), as a surrogate parameter of KC function, and number of CD14-positive KCs. Kruskal-Wallis test and Pearson's correlation coefficient were used to analyze relation among reduction-%LMR, histopathological severity and number of CD14-positive KCs. Results: There were statistically significant differences in reduction-%LMR and number of CD14-positive KCs between NASH and simple steatosis patients (Mann-Whitney test, P<0.001 for all comparisons). Reduction-%LMR decreased with an increase in necroinflammation grade or fibrosis stage. The number of CD14-positive KCs increased with an increase in necroinflammation grade and fibrosis stage (Kruskal-Wallis test, both, P<0.001). A high correlation was seen between number of CD14-positive KCs and reduction-%LMR (Pearson r=0.81; P<0.001). Conclusions: KC phagocytic function evaluated with SPIO-MRI correlated with histopathological severity and number of CD14-positive KCs. These results support the concept that KC phagocytic dysfunction contributes to the pathogenesis of NASH. © 2011 Journal of Gastroenterology and Hepatology Foundation and Blackwell Publishing Asia Pty Ltd.

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. © 2016 Arthroscopy Association of North America.
