Study Design: Case report. Objective: To describe a new method of anterior cervical reconstruction with pedicle screws. Summary of Background Data: Anterior reconstruction after multilevel corpectomy is a challenging technique, and there are many reports on its complications. Graft dislodgement is one of the major complications after long cervical fusion. The main cause of failure seems to be a lack of stability in the conventional reconstruction technique. However, pedicle screws for posterior cervical reconstruction show remarkable stability. We describe a new technique of anterior cervical reconstruction with pedicle screws and fibular strut grafting. Methods: Seven patients with multilevel cervical myelopathy were treated with this new reconstruction technique after a 4-level corpectomy. We describe this new technique and review the patients' clinical history, results of radiographical imaging, and outcomes. Clinical outcomes were assessed preoperatively and at 3 months postoperatively. Postoperative radiographs were assessed 3 months and 6 months postoperatively. Results: The mean operative time was 182 minutes and the mean blood loss was 271 mL. The average Japanese Orthopaedic Association score for cervical myelopathy improved from 11.5 points preoperatively to 14.5 points 3 months postoperatively. No patients experienced major complications, such as neurological deterioration, infection, or massive blood loss. There was no case of reconstruction failure, graft dislodgement, migration, or screw displacement. Conclusion: To our knowledge, this is the first description of an anterior cervical reconstruction approach, using pedicle screws and fibular strut grafting after a 4-level corpectomy. It is likely that this technique will result in better clinical outcomes with fewer complications in the treatment of patients with multilevel cervical myelopathy.

The clinical outcomes of nitinol stents for femoropopliteal arterial (FP) disease in patients on hemodialysis were assessed. Endovascular therapy (EVT) is accepted for symptomatic FP disease. However, the clinical outcomes of patients on dialysis are not well known. A multicenter retrospective study was conducted with data between November 2010 and August 2013. A total of 484 consecutive patients who successfully underwent EVT for FP disease with nitinol stents were recruited and analyzed. Patients were categorized into the hemodialysis group (N=161) and non-hemodialysis group (N=323). The primary measure was primary patency verified by duplex ultrasound at a rest peak systolic velocity (PSVR) of >2.5, and secondary measures were freedom from target lesion revascularization (TLR) and major amputation-free survival (AFS). Average follow-up duration was 19.513.5months. The primary patency rate at 3years was significantly lower in the hemodialysis group than the non-hemodialysis group (33.8 vs. 43.7%; p=0.036). Freedom from TLR at 3years was 55.0% in the hemodialysis group and 66.1% in the non-hemodialysis group (p=0.032). The hemodialysis group showed a significantly lower AFS rate at 3years than the non-hemodialysis group (86.4 vs. 58.2%; p<0.001). In hemodialysis patients, nitinol stent use resulted in a lower patency rate, higher TLR rate, and lower AFS rate compared to non-hemodialysis patients. These data suggest that nitinol stent implantation for FP arteries in hemodialysis patient needs to be reconsidered.

A multi-center phase II study was conducted to evaluate the safety and efficacy of neoadjuvant chemotherapy (NAC) with S-1 plus cisplatin for advanced gastric cancer.The eligibility criteria were clinical T3/T4 or N2, not Stage IV. Patients received two 35-day cycles of S-1 plus cisplatin, and then underwent D2 gastrectomy. The primary endpoint was 3-year progression free survival (PFS). Secondary endpoints were ratio of R0 resection, response rate, adverse events, and overall survival. A sample size of 49 was determined to have 80% power for detecting 15% improvement in the 3-year PFS over 55% at a one-sided alpha of 0.1.Among 53 patients enrolled, 44 patients completed two cycles of NAC (83%), and 48 patients underwent R0 resection (91%). Postoperative complications occurred in 13 patients (26%). A pathological response was confirmed in 24 patients (45%), including four complete responses. The 3-year PFS was 50.7%, while the 3-year OS was 74.9%.Although the observed 3-year PFS rate was worse than expected, NAC with S1 plus cisplatin was safe and led to a high rate of R0 resection. A randomized controlled trial is needed to make conclusions about the effectiveness of NAC in Japanese patients undergoing D2 resection.

Various systemic inflammatory response biomarkers are associated with oncological outcome. We evaluated the superiority of prognostic predictive accuracy between neutrophil-lymphocyte ratio (NLR) and lymphocyte-monocyte ratio (LMR), and the prognostic significance of their perioperative change in patients with bladder cancer undergoing radical cystectomy (RC). We retrospectively analyzed 302 patients who had undergone RC in four institutions. Comparison of predictive accuracy between NLR and LMR was performed using receiver operating characteristic curve analysis. Overall survival (OS) and cancer-specific survival (CSS) were assessed with the Kaplan-Meier method and Cox regression analysis. Preoperative and postoperative LMR showed higher predictive accuracy for OS than NLR did (p=0.034). Applying a cutoff of 3.41, change in perioperative LMR stratified patients into three groups (low, intermediate, and high risk), showing a significant difference in OS and CSS (p<0.001, each), and pathological outcomes. Multivariable analyses for OS and CSS showed that poor changes in LMR (high risk) were an independent prognostic factor (hazard ratio 5.70, 95% confidence interval 3.49-9.32, p<0.001; hazard ratio 4.53, 95% confidence interval 2.63-7.82, p<0.001; respectively). Perioperative LMR is significantly associated with survival in patients with bladder cancer after RC, and it is possibly superior to NLR as a prognostic factor.

Context: Although primary aldosteronism (PA) is the most common cause of endocrine hypertension, histopathological methods to reveal the presence and sites of aldosterone overproduction remain to be established. Objective: The objective of the study was to investigate the significance of immunohistochemical staining to detect CYP11B2 and CYP11B1 in adrenal tissue of patients with PA. Design and Patients: Thirty-two patients with PA who underwent unilateral adrenalectomy were studied. Immunohistochemical staining was performed using anti-CYP11B2 and anti-CYP11B1 antibodies on paraffin-embedded sections. We analyzed the expression of each enzyme semiquan-titatively by scoring staining intensity and correlating it with clinical findings. Results: Twenty-two patients showed positive CYP11B2 immunostaining in their tumors (aldosterone producing adenoma, APA). Four patients with CYP11B2-negative unilateral adenomas and 4 patients without tumors on computed tomography showed aldosterone-producing cell clusters (APCCs) with CYP11B2 immunostaining in the zona glomerulosa (multiple APCCs). The remaining 2 patients had unilateral multiple adrenocortical micronodules and diffuse adrenocortical hyperplasia, respectively. In APA, CYP11B2 score adjusted for tumor volume was positively correlated with plasma aldosterone and negatively correlated with serum potassium. The APA group was divided into 3 subgroups based on relative CYP11B2 and CYP11B1 immunostaining levels. The CYP11B2/CYP11B1-equivalent and CYP11B1-dominant APA groups showed significantly higher serum cortisol after 1 mg dexamethasone and larger tumor size than the CYP11B2-dominant APA group. Conclusions: The present study clearly demonstrates that CYP11B2 immunostaining is a powerful tool for histopathological diagnosis of aldosterone overproduction in PA and for subtype classification of APA, multiple APCCs, unilateral multiple adrenocortical micronodules, and diffuse hyperplasia.

To investigate the characteristics of isolated impaired glucose tolerance (IGT) and isolated impaired fasting glucose (IFG), we analyzed the factors responsible for elevation of 2-hour postchallenge plasma glucose (2 h PG) and fasting plasma glucose (FPG) levels.We investigated the relationship between 2 h PG and FPG levels who underwent 75 g OGTT in 5620 Japanese subjects at initial examination for medical check-up. We compared clinical characteristics between isolated IGT and isolated IFG and analyzed the relationships of 2 h PG and FPG with clinical characteristics, the indices of insulin secretory capacity, and insulin sensitivity.In a comparison between isolated IGT and isolated IFG, insulinogenic index was lower in isolated IGT than that of isolated IFG (0.43 0.34 versus 0.50 0.47, resp.; p < 0.01). ISI composite was lower in isolated IFG than that of isolated IGT (6.87 3.38 versus 7.98 4.03, resp.; p < 0.0001). In isolated IGT group, insulinogenic index showed a significant correlation with 2 h PG (r = -0.245, p < 0.0001) and had the strongest correlation with 2 h PG ( = -0.290). In isolated IFG group, ISI composite showed a significant correlation with FPG (r = -0.162, p < 0.0001) and had the strongest correlation with FPG ( = -0.214).We have elucidated that decreased early-phase insulin secretion is the most important factor responsible for elevation of 2 h PG levels in isolated IGT subjects, and decreased insulin sensitivity is the most important factor responsible for elevation of FPG levels in isolated IFG subjects.

Factor XIII (FXIII) is a fibrin-stabilizing factor consisting of catalytic A subunits (FXIII-A) and carrier B subunits (FXIII-B). Congenital FXIII deficiency is a rare bleeding disorder. Acquired FXIII deficiency resulting from FXIII hypo-synthesis and/or hyperconsumption is a relatively common disorder in which patients seldom bleed. On the contrary, 'autoimmune/acquired hemorrhaphilia XIII/13 due to anti-FXIII antibodies (AH13)' is a rare but life-threatening bleeding disorder. Through a nationwide survey of AH13, we diagnosed aggressive AH13 in a 66-year-old woman. She consulted our department because of a spontaneous hematoma in her hand. After 1.5 months, she also developed an intramuscular hematoma but retained approximately half (52%) of the normal FXIII activities. The patient's bleeding symptoms were aggravated to catastrophic massive bleedings in the large abdominal muscles and intrapelvic and intraperitoneal spaces. Two months after the bleeding onset, she died despite undergoing plasma exchange, which was performed because we were deeply suspicious of the presence of an anti-FXIII inhibitor. Seven days after her death, extremely low FXIII activity (6%) and positive data on anti-FXIII inhibitor were reported by a commercial laboratory. Our dot blot assay detected anti-FXIII-A autoantibodies, afterwards. Thus, the diagnosis of aggressive AH13 as early as possible is necessary to save patients' lives. © 2012 Wolters Kluwer Health | Lippincott Williams & Wilkins.

Malignant pleural mesothelioma (MPM), an aggressive malignant tumor of mesothelial origin associated with asbestos exposure, shows a limited response to conventional chemotherapy and radiotherapy. Therefore, the overall survival of MPM patients remains very poor. Progress in the development of therapeutic strategies for MPM has been limited. We recently reported that the calpain inhibitor, calpeptin exerted inhibitory effects on pulmonary fibrosis by inhibiting the proliferation of lung fibroblasts. In the present study, we examined the preventive effects of calpeptin on the cell growth of MPM, the origin of which is mesenchymal cells, similar to lung fibroblasts. Calpeptin inhibited the proliferation of MPM cells, but not mesothelial cells. It also prevented 1) the expression of angiopoietin (Ang)-1 and Tie-2 mRNA in MPM cells, but not mesothelial cells and 2) the Ang-1-induced proliferation of MPM cells through an NF-kB dependent pathway, which may be the mechanism underlying the preventive effects of calpeptin on the growth of MPM cells. These results suggest potential clinical use of calpeptin for the treatment of MPM.

The aim of this study was to investigate the genetic background of familial clustering of diabetes using genome-wide linkage analysis combined with exome sequencing. We recruited a Japanese family with a 3-generation history of diabetes. The family comprised 16 members, 13 having been diagnosed with diabetes. Nine members had been diagnosed before the age of 40. Linkage analysis was performed assuming an autosomal dominant model. Linkage regions were observed on chromosomes 4q34, 5q11-q13, and 12p11-q22 and the logarithm of odds (LOD) scores were 1.80. To identify the susceptibility variants, we performed exome sequencing of an affected family member. We predicted that the familial clustering of diabetes is caused by a rare non-synonymous variant, and focused our analysis on non-synonymous variants absent in dbSNP131. Exome sequencing identified 10 such variants in the linkage regions, 7 of which were concordant with the affection status in the family. One hundred five normal subjects and 67 lean diabetes subjects were genotyped for the 7 variants; the only variant found to be significantly more frequent in the diabetes subjects than in the normal subjects was the N1072K variant of the early endosome antigen 1 (EEA1) gene (0 in normal subjects and 4 in diabetes subjects, p = 0.022). We therefore propose that the N1072K variant of the EEA1 gene is a candidate mutation for susceptibility to diabetes in the Japanese population. © 2013 Elsevier Inc.

AIM: To search for the optimal surgery for gastrinoma and duodenopancreatic neuroendocrine tumors in patients with multiple endocrine neoplasia type 1. METHODS: Sixteen patients with genetically confirmed multiple endocrine neoplasia type 1 (MEN 1) and Zollinger-Ellison syndrome (ZES) underwent resection of both gastrinomas and duodenopancreatic neuroendocrine tumors (NETs) between 1991 and 2009. For localization of gastrinoma, selective arterial secretagogue injection test (SASI test) with secretin or calcium solution was performed as well as somatostatin receptor scintigraphy (SRS) and other imaging methods such as computed tomography (CT) or magnetic resonance imaging (MRI). The modus of surgery for gastrinoma has been changed over time, searching for the optimal surgery: pancreaticoduodenectomy (PD) was first performed guided by localization with the SAST test, then local resection of duodenal gastrinomas with dissection of regional lymph nodes (LR), and recently pancreas-preserving total duodenectomy (PPTD) has been performed for multiple duodenal gastrinomas. RESULTS: Among various types of preoperative localizing methods for gastrinoma, the SASI test was the most useful method. Imaging methods such as SRS or CT made it essentially impossible to differentiate functioning gastrinoma among various kinds of NETs. However, recent imaging methods including SRS or CT were useful for detecting both distant metastases and ectopic NETs; therefore they are indispensable for staging of NETs. Biochemical cure of gastrinoma was achieved in 14 of 16 patients (87.5%); that is, 100% in 3 patients who underwent PD, 100% in 6 patients who underwent LR (although in 2 patients (33.3%) second LR was performed for recurrence of duodenal gastrinoma), and 71.4% in 7 patients who underwent PPTD. Pancreatic NETs more than 1 cm in diameter were resected either by distal pancreatectomy or enucleations, and no hepatic metastases have developed postoperatively. Pathological study of the resected specimens revealed co-existence of pancreatic gastrinoma with duodenal gastrinoma in 2 of 16 patients (13%), and G cell hyperplasia and/or microgastrinoma in the duodenal Brunner's gland was revealed in all of 7 duodenal specimens after PPTD. CONCLUSION: Aggressive resection surgery based on accurate localization with the SASI test was useful for biochemical cure of gastrinoma in patients with MEN 1. © 2011 Baishideng.
