A multicenter, observational study to evaluate hemostasis following recombinant activated FVII treatment in patients in Japan with congenital factor VII deficiency.

Unlabelled: Reports describing symptoms and treatment of patients with congenital factor VII (FVII) deficiency frequently relate to patients in Europe, while only a small number describe data from Asian countries.This multicenter, prospective observational study (NCT01312636) collected data from 30 sites for 55% of patients registered in 2011 in Japan with congenital FVII deficiency treated with activated recombinant FVII (rFVIIa) for bleeding episodes and/or during surgery.The mean follow-up in 20 eligible patients was 11 months (range 1-49 months).

Solitary pulmonary caseating granulomas: A 5-year retrospective single-center analysis.

Solitary pulmonary caseating granulomas (SPCGs) are a characteristic type of tuberculomas associated with infection with non-tuberculous mycobacteria (NTM) and other microbes; however, their significance remains unclear. The aim of the present study was to describe the clinical characteristics of patients with SPCGs in terms of diagnosis, presence of lung cancer and treatment status. A retrospective analysis of 17 immunocompetent patients with histopathologically confirmed caseating granulomas after undergoing video-assisted thoracoscopic surgery (VATS) was conducted at our center between 2011 and 2015.

[Investigation of the Pathophysiology and Diagnostic Methods Through a Case of Acute HIV Infection in which the Western Blot Method Remained Negative Over the Long Term and the 4th Generation Screening Assay Became Negative for a Certain Period of Time after Initiating Antiretroviral Therapy].

Unlabelled: Confirmatory tests using Western blot (WB) and HIV-1 nucleic acid testing (HIV-1 RNA) following a positive screening test are required for the diagnosis of HIV-1 infection according to the current Japanese guidelines for HIV-1/2 diagnosis. We report herein on a rare case in a patient who remained negative for WB over 10 months in spite of being positive by fourth-generation immunoassays (4thGIA) and who subsequently seroreverted by 4thGIA for three months after initiating antiretroviral therapy.

Case: A man in his early twenties previously visited a hospital because of fever in October 2012.

Successful desensitization therapy involving fluoroquinolone for the treatment of a solitary tuberculoma: A case report and literature review.

The patient was a 31-year-old female with no previous health problems; however, during a health checkup in 2013, a nodule (2.5 cm in diameter) was identified in the S10 area of the left lung. No clinical symptoms were apparent.

Genotypic and phenotypic features of Japanese patients with mild to moderate hemophilia A.

Hemophilia A is the most common inherited bleeding disorder. To better understand the genotypic and phenotypic features of Japanese patients with mild to moderate hemophilia A, we studied 29 unrelated patients with more than 1 % FVIII activity (FVIII:C). Differences were observed in nine of 21 patients in measured FVIII:C levels between the one-stage clotting and chromogenic assays.

[Prevalence of chronic kidney disease among HIV-infected individuals in Japan--a report from two tertiary hospitals].

Background: The improved survival of subjects with human immunodeficiency virus (HIV) has been accompanied by an increased prevalence of chronic kidney disease (CKD). Epidemic of CKD among those with HIV has not yet been evaluated in multiple tertiary hospitals in Japan.

Methods: A cross-sectional study was conducted in 2011 at Tokyo Metropolitan Komagome Hospital (TMKH) and Tokyo Medical University Hospital (TMUH).

[Double mutation, a 2-bp deletion and Val211Ile, in the blood coagulation factor IX gene of a patient with severe hemophilia B].

Hemophilia B is an X-linked bleeding disorder caused by the absence or reduced activity of coagulation factor IX (FIX). Here, we report a double mutation in the FIX gene (F9) in a Japanese patient with severe hemophilia B. FIX activity (FIX:C) was measured with a one-step functional assay.
