BACKGROUND: The antidiabetic drug teneligliptin is a novel dipeptidyl peptidase-4 (DPP-4) inhibitor with a thiazolidine-specific structure. This study aimed to investigate whether teneligliptin can activate PPARγ directly and/or indirectly in cell-based assays. METHODS: Promoter assays using the reporter construct driven under the control of the SV40 promoter and the PPAR response element (PPRE) were performed. Luciferase activity was measured after a 3-day incubation of vector-transduced cells with various concentrations of teneligliptin...

Idiopathic ventricular premature contractions (VPCs), defined as VPCs in the absence of obvious structural heart disease, are one of the common types of arrhythmia in clinical practice. They are sometimes complicated with non-sustained ventricular tachycardia (VT), and/or sustained VT with almost same QRS morphology in 12 leads ECG. Idiopathic VT (IVT) commonly occurs by focal mechanisms and the origins are distributed in a variety of sites in both ventricles. In this article, the clinical characteristics of IVT/IVPCs, the diagnostic algorithm, and how to ablate them will be reviewed...

Sleep-disordered breathing (SDB) is a risk factor for cardiovascular disease including acute coronary syndrome and acute myocardial infarction, and treating SDB prevents their development and recurrence and improves a patient's prognosis. Therefore, SDB is considered a therapeutic target for cardiovascular disease. In 2010, the Japanese Circulation Society published guidelines for the diagnosis and treatment of SDB in patients with cardiovascular disease. However, therapeutic intervention for patients with SDB was recently reported not to suppress the development or deterioration of cardiovascular disease in three middle- to large-sized randomized clinical trials: the SERVE-HF trial, which examined the effects of adaptive servo-ventilation (ASV) on patients with chronic heart failure (CHF) and central sleep apnea; the CAT-HF trial, which examined the effects of ASV therapy on patients with CHF after acute deterioration; and the SAVE study, which examined the secondary preventive effect of continuous positive airway pressure (CPAP) on patients with ischemic heart disease who had mild to moderate obstructive sleep apnea...

We report here a case of systemic lupus erythematosus (SLE) with pulmonary hemorrhage and anti-glomerular basement membrane (anti-GBM) antibodies. A 42-year-old woman was admitted to our hospital with complaints of exanthema, arthralgia, shortness of breath, and hemoptysis. Plain chest computed tomography (CT) scan revealed pericardial effusion, bilateral pleural effusions, and pulmonary hemorrhage. Laboratory findings on admission revealed proteinuria, microscopic hematuria, anemia, leukopenia, hypoalbuminemia, hypocomplementemia, and slightly elevated levels of serum creatinine...

We report on two siblings with early onset lysosomal acid lipase deficiency or Wolman disease. Their parents had a consanguineous marriage. The children showed evidence of abdominal distension and failed to thrive, despite having regular nutrition. At 3-4 months of age, their abdominal distension and jaundice progressed rapidly and they died of liver failure. Sebelipase alfa, a recombinant form of human lysosomal acid lipase has recently been used as an enzyme replacement therapy in patients with later-onset cholesteryl ester storage disease...

More than 6,000 people died in the Great Hanshin (Kobe) Earthquake in 1995, and it was later reported that there were around 500 preventable trauma deaths. In response, the Japanese government developed the helicopter emergency medical service in 2001, known in Japan as the "Doctor-Heli" (DH), which had 46 DHs and 2 private medical helicopters as of April 2016. DHs transport physicians and nurses to provide pre-hospital medical care at the scene of medical emergencies. Following lessons learned in the Great East Japan Earthquake in 2011, a research group in the Ministry of Health, Labour and Welfare developed a command and control system for the DH fleet as well as the Disaster Relief Aircraft Management System Network (D-NET), which uses a satellite communications network to monitor the location of the fleet and weather in real-time during disasters...

A 61-year-old woman was admitted to our hospital because of muscle paralysis and was found to have severe hypokalemia. A gallium-67 scintigram revealed a positive accumulation in the bilateral salivary glands, and a labial minor salivary gland biopsy demonstrated a massive lymphocyte infiltrate around the salivary ducts. She was diagnosed with Sjögren's syndrome (SS) associated with renal tubular acidosis. Renal biopsy revealed tubulointerstitial nephritis with a mild focal infiltration of lymphocytes and plasma cells...

BACKGROUND: Photoreceptors differentiated from somatic cells are a useful tool for transplantation and drug screening. We previously showed that photosensitive cells are differentiated from human fibroblasts by direct reprogramming. In induced pluripotent stem (iPS) cells or embryonic stem (ES) cells, the properties of differentiated cells differ among the source of cell lines. However, whether or not the properties of the photosensitive cells produced by direct reprogramming are controlled by the origin of the cell line remains unknown...

INTRODUCTION: Various innovations for preventing complications and improving a patient's quality of life have been implemented for peritoneal dialysis (PD), which was established in Japan approximately 35 years ago and introduced at our hospital in 1999. Herein, we investigate the outcomes of patients undergoing PD to identify approaches for improving their long-term prognosis. METHODS: This retrospective study included 114 patients who underwent PD between September 1999 and August 2017 and included various parameters such as patient survival rate, technical survival rate, cause (s) of PD withdrawal, incidence of peritonitis, dialysis duration, and change in residual renal function (RRF)...

Medial epicondyle fractures of the humerus account for 11%-20% of all elbow injuries in children. Although intra-articular incarceration of the medial epicondyle occurs in 5%-18% of medial epicondyle fractures associated with an elbow dislocation, the mechanism of intrusion of the fracture fragment is unknown. We report a case of an irreducible elbow fracture and dislocation due to incarceration of the medial epicondyle fragment of the humerus, classified as a Watson-Jones type 3 fracture of the medial epicondyle, and present the mechanism of the intra-articular incarceration of the medial epicondyle fragment...

Purpura fulminans associated with antithrombin 3 (AT 3) deficiency is very rare in adults and neonates. It can be categorized into three principal forms - neonatal, idiopathic and acute infectious. Purpura fulminans has been reported to cause cardiac, pulmonary and renal damage in rare cases. We describe an adult case of purpura fulminans developing in association with AT 3 deficiency without infection following a surgical procedure, and acute kidney injury (AKI) developing secondary to rhabdomyolysis and disseminated intravascular coagulation (DIC)...

Carcinosarcoma (CS) is a rare tumor, consisting of both carcinomatous and sarcomatous components. In this paper, we present a case of CS arising from a pleomorphic adenoma (PA) of the submandibular gland. A 64-year-old Japanese man presented with a left submandibular mass that had developed for 20 years with complaints of pain for the last 3 months. Magnetic resonance imaging showed a lesion involving the left submandibular gland. The patient underwent total dissection of the left submandibular gland and left cervical lymph nodes...

Verrucous carcinoma (VC) is an uncommon, distinct type of well-differentiated squamous cell carcinoma. Here we present two cases of VC, one arising from the lower leg and the other from genital skin. Case 1, a female patient, aged 95 years, had a brownish verrucous plaque on her right lower leg. Histopathologically, epithelial tumor cells grew pushing the stroma, while the basement membrane was intact. No prominent cellular atypia or hyperchromatin was found. Case 2, a male patient, aged 53 years, had a verrucous plaque at the border between his scrotum and inner aspect of his thigh...

PURPOSE: The aim of this study was to identify a useful biomarker to predict the efficacy of polymyxin B-immobilized fiber direct hemoperfusion (PMX-DHP) in patients with septic shock. METHODS: The 44 patients included in this study were divided into two groups. Group A had an increase in systolic blood pressure (SBP) over 30 mmHg after PMX-DHP treatment. Group B had an increase in SBP less than 30 mmHg after PMX-DHP treatment. We evaluated the clinical characteristics and demographics of both groups...

The introduction of the Haemophilus influenzae type b (Hib) vaccine and the 7-valent pneumococcal conjugate vaccine (PCV7) has led to dramatic reductions in cases of invasive H. influenzae disease and invasive pneumococcal disease (IPD). After the introduction of the PCV7 and the 13-valent pneumococcal conjugate vaccine (PCV13), the number of children with IPD markedly decreased in our hospital. However, since 2015, three children with IPD have been admitted to our hospital. We analyzed the serotype, multilocus sequence type, and antimicrobial susceptibility of Streptococcus pneumoniae strains isolated in these newly diagnosed cases...

BACKGROUND AND PURPOSE: It is clinically important to evaluate time course changes in symptomatic middle cerebral artery (MCA) stenotic plaques because of likely recurrence. The objective of this study is to determine whether contrast-enhanced high-resolution magnetic resonance imaging (MRI) is a feasible method for this purpose. METHODS: Contrast-enhanced, high-resolution, 3D turbo spin-echo images with low refocusing flip angle control (3D LOWRAT) applied to 7 patients with symptomatic MCA stenosis were evaluated at the initial (1 month after stroke onset) and follow-up (7 months after stroke onset) stages, and statistical variables, including plaque-to-thalamus signal intensity ratio, degree of stenosis, and stroke recurrence obtained at the 2 stages, were compared...

The incidence of atopic diseases, including atopic dermatitis (AD), food allergies, allergic rhinitis, and asthma, has increased in recent decades, and currently affects approximately 20% of the population. Atopic march is the development of AD in infancy and subsequent food allergies, allergic rhinitis, and asthma in later childhood. Patients with infantile eczema may develop typical symptoms of AD, allergic rhinitis, and asthma at certain ages. Some patients' symptoms persist for several years, whereas others may have resolution with aging...

Anaplastic thyroid carcinoma (ATC) accounts for only 1 to 2% of all thyroid carcinomas, but it is one of the most lethal neoplasms in humans. To obtain further insights into this "orphan disease," we have established the ATC Research Consortium of Japan (ATCCJ) in 2009. It represents a multicenter registry for ATC that have been treated in Japan. To date, 67 institutions have taken part in the collaborative research system and over 1,200 cases have been accumulated in its database. Using this big data, several retrospective studies were carried out to evaluate 1) prognostic factors to determine initial treatment policy, 2) significance of extended radical surgery for Stage IVB cases, 3) characteristics of ATC incidentally found on pathological examination and 4) pathological features of ATC with long-term survival...
