Retrospective study on the possibility of an SFTS outbreak associated with undiagnosed febrile illness in veterinary professionals and a family with sick dogs in 2003.

Introduction: Severe fever with thrombocytopenia syndrome (SFTS) is an emerging tick-born disease and its animal-to-human transmission has come to attention recently. During our sero-survey of SFTS virus (SFTSV) among veterinary professionals in 2018, a veterinarian and his assistant working in an animal hospital were tested positive by enzyme-linked immunosorbent assay (ELISA). An additional survey implied a cluster of SFTS cases in which four more people, a family who brought two sick dogs to the animal hospital in 2003, were involved.

Efficacy of combined androgen blockade therapy in patients with metastatic hormone-sensitive prostate cancer stratified by tumor burden.

Objective: To determine the effect of combined androgen blockade with a first-generation anti-androgen on the prognoses of metastatic hormone-sensitive prostate cancer patients stratified by tumor burden.

Methods: We retrospectively analyzed the cases of metastatic hormone-sensitive prostate cancer patients who were treated with androgen deprivation therapy in 2008-2017 at 30 institutions in Japan. To compare the overall survival and progression-free survival rates of the patients treated with castration monotherapy and combined androgen blockade, we carried out a Cox proportional hazards regression analysis using both inverse probability of treatment weighting and instrumental variables methods.

Guide sheath non-guide sheath method for endobronchial ultrasound-guided biopsy of peripheral pulmonary lesions: a multicentre randomised trial.

Background: Guide sheaths (GSs) have been widely used during radial probe endobronchial ultrasound-guided transbronchial biopsy (rEBUS-TBB) of peripheral pulmonary lesions. However, it remains unknown whether a GS enhances the diagnostic yield. We compared the diagnostic yields of small peripheral pulmonary lesions between rEBUS-TBB with and without a GS.

Duplications in the G3 domain or switch II region in HRAS identified in patients with Costello syndrome.

Costello syndrome (CS) is an autosomal-dominant disorder characterized by distinctive facial features, hypertrophic cardiomyopathy, skeletal abnormalities, intellectual disability, and predisposition to cancers. Germline variants in HRAS have been identified in patients with CS. Intragenic HRAS duplications have been reported in three patients with a milder phenotype of CS.

[A Cohort Study on the Prognosis of Patients with Urothelial Carcinoma Using the Miyazaki Urological Cancer Database (MUCD)].

Miyazaki Urological Cancer Database (MUCD) is a web-based database containing background, treatment, and prognosis of patients with prostate, renal, and urothelial cancers diagnosed in Miyazaki. We entered information on patients diagnosed with urothelial carcinoma from 2014 to 2018 at 4 of the 17 facilities that diagnose urothelial carcinoma in Miyazaki Prefecture. We analyzed the overall survival for bladder cancer and upper urinary tract cancer, and examined its correlation with the presence of symptoms, urine cytology, and clinical TNM classification.

Reduced urinary release of AQP1- and AQP2-bearing extracellular vesicles in patients with advanced chronic kidney disease.

Although several studies have shown that release of water channel proteins, aquaporin 1 (AQP1) and AQP2 in urinary extracellular vesicles (uEV-AQP1 and -AQP2), were altered in experimental kidney injury models, their release in human chronic kidney disease (CKD) has been largely unexplored. The aim of the present study was to clarify whether the release of uEV-AQP1 and -AQP2 is altered in patients with CKD. Urine samples were collected from 15 healthy volunteers (normal group) and 62 CKD patients who were categorized into six glomerular filtration rate (GFR) categories (G1, G2, G3a, G3b, G4, and G5) in between 2005 and 2016 at Miyazaki Prefectural Miyazaki Hospital, Japan.

Clinical Outcomes of Mixed Response to Pembrolizumab in Advanced Urothelial Carcinoma After Platinum-based Chemotherapy.

Background/aim: Despite the presence of a mixed response (MR) in patients with urothelial carcinoma (UC) who receive immune checkpoint inhibitors, the clinical outcome of these patient has not been reported. We evaluated the clinical outcome of MR to pembrolizumab for advanced UC.

Patients And Methods: Advanced UC patients who received pembrolizumab after platinum-based chemotherapy failure with measurable disease in multiple organs were retrospectively analyzed.

Serial evaluation of the pharmacokinetics of ponatinib in patients with CML and Ph + ALL.

Although tyrosine kinase inhibitors (TKIs) play a crucial role in the treatment of chronic myeloid leukemia (CML) and Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph + ALL), intolerance and resistance to TKIs have been serious problems. Due to a lack of research, the importance of the pharmacokinetics (PK) of TKIs is currently unclear. We examined the PK of the third-generation TKI ponatinib to monitor side effects and efficacy during treatments for one patient with CML-chronic phase (CP-CML) and two who received allogeneic hematopoietic stem cell transplantation (allo-HSCT), one for CML-blastic crisis (BC-CML) and one for Ph + ALL.

Laparoscopic repositioning of an aberrant right hepatic artery and hepaticojejunostomy for pediatric choledochal cyst: A case report.

Acquired Thrombotic Thrombocytopenic Purpura Without Anti-ADAMTS13 Antibody Caused by Influenza A (H1N1) Virus Successfully Treated by Plasma Exchange: A Case Report.

BACKGROUND Thrombotic microangiopathy, characterized by microangiopathic hemolytic anemia, thrombocytopenia, and organ damage by microvascular thrombosis, has a high mortality rate; therefore, early diagnosis and treatment are important. Thrombotic thrombocytopenic purpura is caused by a deficiency of a disintegrin-like and metalloproteinase with thrombospondin type 1 motifs 13 (ADAMTS13), and results in thrombotic microangiopathy. Influenza virus causes thrombotic thrombocytopenic purpura by inducing immunoglobulin G autoantibodies against ADAMTS13.

Tracheal Mucoepidermoid Carcinoma Mimicking Deteriorated Bronchial Asthma during Pregnancy.
