Chronic graft versus host disease (cGVHD) remains a major problem for long survivors after allogeneic hematopoietic stem cell transplantation (HSCT). Currently, corticosteroid therapy is effective for cGVHD as the first line therapy. However, prolonged therapy with corticosteroids causes various severe adverse events. To develop the new therapeutic strategy of cGVHD, we have launched a multicenter phase I/IIa clinical trial of low dose subcutaneous interleukin-2 (IL-2) for treatment of steroid refractory cGVHD, which is constituted of 2 sequential phases (induction phase and maitanance phase)...

Docetaxel is a standard treatment for patients with advanced or recurrent breast cancer. The recommended dose is 60 to 100 mg/m2. Previous study have shown that the tumor response rates of patients who received docetaxel monotherapy at doses of 60, 75, and 100 mg/m2 were 22.1% , 23.3% , and 36.0% , respectively, and there was a significant relationship between the dose and response. In Europe and the United States, docetaxel is approved at a dose of 100 mg/m2, and Japanese guidelines also recommend a dose of 100 mg/m2...

Stent placement is an essential treatment for airway diseases. Although self-expandable metallic stents and silicone stents are commonly applied for the treatment of airway diseases, these stents are unsuitable for the treatment of small airway diseases encountered in pediatric patients and lung transplant recipients with airway complications. Currently, only vascular balloon-expandable metallic stents are available for the treatment of small airway diseases; however, little research has been conducted on the use of these stents in this field...

Although accurate bracket placement is essential for orthodontic treatment, many practitioners apply brackets indiscriminately with direct or indirect bonding techniques. Nonetheless, there have been few prospective clinical comparisons of the 2 techniques. We will therefore conduct a single-center, randomized control trial in 100 patients aged 12 years and diagnosed with malocclusion. All patients will receive orthodontic treatment using brackets with direct or indirect bonding techniques. The primary endpoints will be the total treatment time, occlusal index, discomfort at bonding, and oral hygiene after bonding...

Chronic graft-versus-host disease (GVHD) is a major cause of late death and morbidity following allogeneic hematopoietic cell transplantation (HSCT). Retinoic acid (tamibarotene) exerts multiple effects on cell differentiation and is clinically used for the treatment of acute promyelocytic leukemia. Tamibarotene down-regulates both Th1 and Th17 differentiation in donor T cells after allogeneic HSCT, resulting in attenuation of experimental chronic GVHD. Based on preclinical data, we have launched a phase II study of tamibarotene in patients with steroid-refractory chronic GVHD...

Although intermittent pneumatic compression (IPC) has become common as perioperative prophylaxis for venous thromboembolism (VTE) consisting of pulmonary thromboembolism (PE) and deep vein thrombosis (DVT), the prophylactic effect against VTE, especially lethal PE, is not yet satisfactory. Therefore, pharmacologic prophylaxis, such as with enoxaparin, is desirable. While the efficacy and safety of enoxaparin have been proven in several clinical trials, concern about bleeding with longterm (at least 7 days) use have potentially decreased its widespread adoption...

We report a case of a granulocyte colony-stimulating factor (G-CSF)-producing gallbladder tumor associated with fever in a middle-aged female. Preoperative blood analysis showed leukocytosis with elevated levels of C-reactive protein and G-CSF. We resected the liver at S4a+S5, with regional lymph node dissection and partial resection of the duodenum. Histology revealed undifferentiated carcinoma with spindle and giant cells and papillary adenocarcinoma. Immunohistochemistry revealed Stage IIIB G-CSF-producing gallbladder cancer...

Advances in critical care medicine have made it possible to sustain vital organ systems in brain-dead patients. One clinical scenario besides donor organ retrieval in which a benefit may be gained from continuing life support is pregnancy. A pregnant woman in her late 30's at 23 weeks gestation exhibiting worsening depression was referred to the Department of Psychiatry. One day after admission she attempted suicide by hanging and suffered a cardiopulmonary arrest. A fetal heart beat and fetal motion was confirmed immediately after resuscitation...

Kikuchi-Fujimoto disease (KFD) is a benign cause of self-limiting subacute necrotizing lymphadenitis. KFD is rarely complicated with reactive hemophagocytic lymphohistiocytosis (HLH), and the clinical features of the simultaneous occurrence of these conditions are uncertain. A 30-year-old Japanese man with a persistent fever and sore throat presented to our hospital for treatment. Laboratory analysis showed bicytopenia, and radiological studies showed systemic lymphadenopathy accompanied by splenomegaly. A bone marrow examination showed hemophagocytic macrophages, suggesting HLH...

A 71-year-old man presented with a high fever, polyarthralgia, petechiae and palpable purpura accompanied by livedoid change on his legs and feet. Histopathological findings of the purpura revealed perivascular infiltration of neutrophils, mononuclear cells, and nuclear debris, and extravasation of red cells mainly in the upper dermis: all signs consistent with leukocytoclastic vasculitis. Small vessel thrombi, which are characteristic features of septic vasculopathy, were also observed. Direct immunofluorescence showed negative results...

Methylguanidine (MG) is a known nephrotoxin and neurotoxin, and an intracisternal injection of MG can induce convulsions in experimental animals. In this in vitro study, we examined the inhibitory effects of the antiepileptic agent zonisamide (ZNS) on hydroxyl radicals (•OH) generated from MG by using an electron spin resonance (ESR) technique. ZNS scavenged •OH generated from MG in a dose-dependent manner through direct scavenging during the auto-oxidation of MG. The rate constant of ZNS reacting with the •OH was at a near diffusion-controlled rate...

Sarcopenia following liver surgery has been reported as a predictor of poor prognosis. Here we investigated predictors of outcomes in patients with hepatocellular carcinoma (HCC) and attempted to establish a new comprehensive preoperative assessment protocol. We retrospectively analyzed the cases of 254 patients who underwent curative hepatectomy for HCC with Child-Pugh classification A at our hospital between January 2007 and December 2013. Sarcopenia was evaluated by computed tomography measurement. The influence of sarcopenia on outcomes was evaluated...

In a longitudinal study, we examined the link between changes in physical activity and changes in health-related quality of life (HRQOL) in patients on chronic hemodialysis. Seventy-one patients (43 males, 28 females; aged 70.9±10.6 years) on chronic hemodialysis in September 2013 were enrolled. The data of the 43 patients whose complete measurements were taken again in September 2014 were used for the longitudinal analysis. Clinical parameters including age, height, dry weight, duration of hemodialysis, blood pressure (BP), blood triglyceride and HDL cholesterol levels, physical activity, and HRQOL were evaluated...

Although a 0.3 Bangerter filter, which reduces visual acuity, is frequently used for treating moderate amblyopia, the effects on gross stereopsis are not well known. This study quantitatively evaluated whether gross stereopsis is degraded by a Bangerter filter. Seven healthy subjects (median age: 29 years) participated in this psychophysical study. Targets with crossed disparities of 1°, 2°, 3°, 4°, and 5° were randomly presented on a three-dimensional television display. The subjects indicated the point at which the targets popped out from the television screen (matching method)...

In recent years, it has become evident that molecular hydrogen is a particularyl effective treatment for various disease models such as ischemia-reperfusion injury; as a result, research on hydrogen has progressed rapidly. Hydrogen has been shown to be effective not only through intake as a gas, but also as a liquid medication taken orally, intravenously, or locally. Hydrogen's effectiveness is thus multifaceted. Herein we review the recent research on hydrogen-rich water, and we examine the possibilities for its clinical application...

A study to evaluate the effect of metformin on the immune system was commenced in July 2014. Metformin is one of the most commonly prescribed drugs for type 2 diabetes, and previous studies have reported that metformin has an anti-tumor effect. The aim of this study is to evaluate the efficacy of metformin on the immune system in human cancer patients in vivo. The primary outcome parameter will be the rate change in the population of CD8+ T cells, which produce multiple cytokines.
