Multicenter, Open-Label, Randomized Controlled Trial of Warfarin and Edoxaban Tosilate Hydrate for the Treatment of Deep Vein Thrombosis in Persons with Severe Motor Intellectual Disabilities.

Sudden death in patients with severe motor and intellectual disabilities (SMID) is sometimes caused in part by pulmonary thromboembolism (PTE), and deep venous thrombosis (DVT) has drawn attention as a possible embolic source. Warfarin, which is a conventional therapeutic agent, is not easy to control appropriately, and daily management can be especially difficult in SMID patients. On the other hand, edoxaban tosilate hydrate, which has been newly approved for insurance coverage for the treatment of DVT, is not listed in the Guidelines for the Diagnosis, Treatment and Prevention of Pulmonary Thromboembolism and Deep Vein Thrombosis (DVT-PTE guidelines).

Longterm Outcomes of 188 Japanese Patients with Eosinophilic Granulomatosis with Polyangiitis.

Objective: Patients with eosinophilic granulomatosis with polyangiitis (EGPA) frequently experience relapses, which lead to cumulative organ damage. In this retrospective observational study, we aimed to reveal the risk factors for relapse in EGPA.

Methods: A total of 188 Japanese patients with EGPA diagnosed between 1996 and 2015 were identified from medical records in 10 hospitals.

Comparison of DWIBS/T2 image fusion and PET/CT for the diagnosis of cancer in the abdominal cavity.

Fusion images of diffusion-weighted whole-body imaging with background body signal suppression and T2-weighted image (DWIBS/T2) demonstrate a strong signal for malignancies, with a high contrast against the surrounding tissues, and enable anatomical analysis. In the present study, DWIBS/T2 was compared with F-fluorodeoxyglucose (F-FDG) positron emission tomography/computed tomography (PET/CT) for diagnosing cancer in the abdomen. Patient records, including imaging results of examination conducted between November 2012 and May 2014, were analyzed retrospectively.

Diagnostic accuracy of diffusion-weighted whole-body imaging with background body signal suppression/T2-weighted image fusion for the detection of abdominal solid cancer.

Diffusion-weighted whole-body imaging with background body signal suppression (DWIBS) images show significant contrast for cancer tissues against non-cancerous tissues. Fusion of a DWIBS and a T2-weighted image (DWIBS/T2) can be used to obtain functional, as well as anatomic, information. In the present study, the performance of DWIBS/T2 in the diagnosis of abdominal solid cancer was evaluated.

Abdominal ultrasonography for patients with abdominal pain as a first-line diagnostic imaging modality.

The utility and limitations of abdominal ultrasonography (US) were retrospectively evaluated as a first-line diagnostic imaging modality in patients with abdominal pain. Hospital records from patients subjected to abdominal US as a first-line diagnostic imaging examination at the National Hospital Organization Shimoshizu Hospital (Yotsukaido, Japan) from April 2010 to April 2015 were analyzed. Only those patients who underwent abdominal US to diagnose abdominal symptoms were included in the present study.

Immunosuppressive agents are associated with peptic ulcer bleeding.

Peptic ulcer bleeding can be fatal. Non-steroidal anti-inflammatory drugs (NSAIDs), corticosteroids and immunosuppressive agents are administered for long-term usage. The present study assessed the association between peptic ulcer bleeding and administration of NSAIDs, corticosteroids and immunosuppressive agents.

Diffusion-weighted whole-body imaging with background body signal suppression/T2 image fusion for the diagnosis of colorectal polyp and cancer.

Diffusion-weighted whole-body imaging with background body signal suppression/T2 image fusion (DWIBS/T2) is useful for the diagnosis of cancer as it presents a clear contrast between cancerous and non-cancerous tissue. The present study investigated the limitations and advantages of DWIBS/T2 with regards to the diagnosis of colorectal polyp (CP) or cancer (CRC). The current study included patients diagnosed with CP or CRC following colonoscopy, who were subjected to DWIBS/T2 between July 2012 and March 2015.

Cell death in a co-culture of hepatocellular carcinoma cells and human umbilical vascular endothelial cells in a medium lacking glucose and arginine.

Human primary hepatocytes are able to survive in a medium without glucose and arginine that is instead supplemented with galactose and ornithine (hepatocyte selection medium; HSM). This is because the cells produce glucose and arginine by the action of galactokinase (GALK) and ornithine carbamoyltransferase (OTC), respectively. It was expected that hepatocellular carcinoma (HCC) cells do not survive in HSM.

Clinical Epidemiology and Treatment of Febrile and Afebrile Convulsions With Mild Gastroenteritis: A Multicenter Study.

Background: We investigated features and responses to treatment in patients with febrile and afebrile convulsions with mild gastroenteritis and characterized convulsions with rotavirus and norovirus gastroenteritis.

Methods: We conducted a prospective, observational study to evaluate patients with febrile and afebrile convulsions with mild gastroenteritis who were hospitalized between November 2011 and March 2014 at 13 facilities in the National Hospital Organization. We classified the patients into two groups: presence or absence of fever.

Severity and Diurnal Improvement of Morning Stiffness Independently Associate with Tenosynovitis in Patients with Rheumatoid Arthritis.

Background And Objectives: Although morning stiffness has long been recognized as a characteristic feature of rheumatoid arthritis (RA), it is no more included in the 2010 ACR/EULAR Classification Criteria or in the current major instruments for evaluating disease activity of RA. In this cross-sectional study, we aimed to determine the independent value and the optimal measurement of morning stiffness by clarifying the associations between morning stiffness and synovial inflammation.

Patients And Methods: We enrolled 76 consecutive RA patients who underwent musculoskeletal ultrasound examination and agreed to participate in the study.

Signal Intensity of Superb Microvascular Imaging Correlates with the Severity of Acute Cholecystitis.

Evaluation of the severity of acute cholecystitis is critical for the management of this condition. Superb microvascular imaging (SMI) enables the assessment of slow blood flow of small vessels without any contrast medium. An 84-year-old man visited our hospital with right upper abdominal pain.

Change ratio of hemoglobin has predictive value for upper gastrointestinal bleeding.

The present study aimed to identify novel predictors of upper gastrointestinal (GI) bleeding by assessing change ratios of blood test variables. Records of 1,023 patients (431 men and 592 women) who underwent endoscopy between October 2014 and September 2015 at the National Hospital Organization Shimoshizu Hospital (Yotsukaido, Japan) were retrospectively analyzed. Patients whose blood test variables for the time-point of endoscopy and three months previously were available were enrolled and subsequently categorized into a group with and another one without upper GI bleeding (n=32 and 84, respectively), and the respective change ratios were calculated for each group.

Low hemoglobin levels are associated with upper gastrointestinal bleeding.

Upper gastrointestinal (GI) bleeding can be fatal. Blood test variables were reviewed in search of threshold values to detect the presence of occult upper GI bleeding. The records of 1,023 patients who underwent endoscopy at the National Hospital Organization Shimoshizu Hospital from October 2014, to September 2015, were retrospectively reviewed.

Duodenal Adenocarcinoma Diagnosed from a Biopsy Specimen of a Depressed Lesion Obtained by Magnifying Endoscopy.

Biopsies are necessary for the management of duodenal tumors. However, the most suitable targets for biopsy are not known. An 82-year-old woman who regularly visited our hospital for rheumatoid arthritis underwent abdominal ultrasonography.

Characteristics of colorectal cancer diagnosed with screening abdominal ultrasonography.

Patient records were retrospectively analyzed to elucidate the characteristics of patients with colorectal cancer (CRC) diagnosed with screening abdominal ultrasound (US). Patients diagnosed with CRC using abdominal US [localized irregular wall thickening (W) or a hypoechoic mass with a hyperechoic mass (M)] were enrolled. The patients were subjected to colonoscopy and treated surgically between March, 2010 and January, 2015.

Diffusion-weighted whole-body imaging with background body signal suppression/T2-weighted image fusion of gastrointestinal cancers.

Diffusion-weighted whole-body imaging with background body signal suppression (DWIBS) yields positive results for cancer against the surrounding tissues. The combination of DWIBS and T2-weighted images (DWIBS/T2) in the diagnosis of gastrointestinal tract cancers was retrospectively analyzed in the present study. Patients were subjected to magnetic resonance imaging after cancer was diagnosed through specimens obtained via biopsy or endoscopic mucosal resection.

Elevated C-reactive protein level predicts lower gastrointestinal tract bleeding.

Lower gastrointestinal (GI) bleeding can be caused by colorectal polyps or cancer. The aim of the present study was to identify blood test variables and medications that can predict lower GI bleeding, which would allow for appropriate colonoscopy. The medical records of patients who underwent colonoscopy from September 2014 to September 2015 were retrospectively analyzed.
