Pravastatin prevents colitis-associated carcinogenesis by reducing CX3CR1 M2-like fibrocyte counts in the inflamed colon.

Colorectal cancer (CRC) resulting from chronic inflammation is a crucial issue in patients with inflammatory bowel disease (IBD). Although many reports established that intestinal resident CX3CR1 macrophages play an essential role in suppressing intestinal inflammation, their function in colitis-related CRC remains unclear. In this study, we found that colonic CX3CR1 macrophages, which were positive for MHC-II, F4/80 and CD319, promoted colitis-associated CRC.

A case of ulcerative colitis with a variety of autoimmune diseases including ankylosing spondylitis, type 2 autoimmune pancreatitis, and primary sclerosing cholangitis.

Ankylosing spondylitis (AS), primary sclerosing cholangitis (PSC), and autoimmune pancreatitis (AIP) are known as extraintestinal manifestations (EIMs) of ulcerative colitis (UC). A 74-year-old Japanese man visited our hospital because of white stool. He had been diagnosed with AS when he was 30 years old, and he was HLA-B27-positive.

Protocol for the nationwide registry of patients with polycystic kidney disease: japanese national registry of PKD (JRP).

Background: Autosomal dominant polycystic kidney disease (ADPKD) and autosomal recessive polycystic kidney disease (ARPKD) are major genetic polycystic kidney diseases that can progress to end-stage kidney disease (ESKD). Longitudinal data on the clinical characteristics associated with clinical outcomes in polycystic kidney disease (PKD), including the development of ESKD and cardiovascular disease (CVD) are lacking in Japan. To address this unmet need the authors are establishing a novel, web-based, Nationwide Cohort Registry Study-the Japanese Registry of PKD (JRP).

Prognostic value of a mandibular canal staging system for primary lesions in patients with lower gingival squamous cell carcinoma: a multicenter, retrospective study.

Background: The Union for International Cancer Control and American Joint Committee on Cancer tumor staging system is used globally for treatment planning. As it may be insufficient for tumor staging of lower gingival carcinomas, we proposed the mandibular canal tumor staging system. In this study, we aimed to compare the two systems for such tumor staging and to identify prognostic markers.

[A case of aortic thrombus during chemotherapy for esophageal cancer].

A 59-year-old man presented to our hospital with a chief complaint of epigastric pain. Pertinent history included a distal gastrectomy for gastric cancer and alcohol dependence. He underwent contrast-enhanced computed tomography (CT) and esophagogastroduodenoscopy, which led to a diagnosis of esophageal cancer (cT2N2M1, stage IVb).

The Diagnosis of Esophageal Tuberculosis through an Endoscopic Ultrasound-guided Fine-needle Aspiration Biopsy.

A 54-year-old woman presented with an elevated esophageal lesion. Computed tomography (CT) and magnetic resonance imaging revealed a mass in the pancreatic head. Endoscopic ultrasound (EUS) showed a well-defined, round, hypoechoic mass, which was considered lymph node enlargement.

Renal Medullary Angiitis Associated with Cutaneous Leukocytoclastic Vasculitis.

Renal medullary angiitis is characterized by interstitial hemorrhaging in the medulla with neutrophil infiltration. An 81-year-old man presented with a fever, kidney dysfunction, and purpura of the legs, which was diagnosed as leukocytoclastic vasculitis. Proteinase 3 antineutrophil cytoplasmic antibodies were weakly positive.

Association of eye strain with dry eye and retinal thickness.

Purpose: The purpose of this cohort study was to investigate the association between the prevalence of abnormal ocular examination results and the common visual symptoms of eye strain, blurred vision and photophobia.

Methods: Consecutive first-visit outpatients with best-corrected visual acuity better than 20/30 in both eyes were enrolled and those with a history of intra-ocular lens implantation and glaucoma were excluded. Dry eye-related examinations and retinal thickness measurement were conducted.

Positive Ascites Cytology, Postoperative Chemotherapy and Prognosis of Stage I Ovarian Clear Cell Carcinoma.

Background/aim: Ovarian clear cell carcinoma (CCC) is associated with a poor prognosis and is resistant to chemotherapy. The aim of this study was to investigate the prognosis of CCC in Mie prefecture and to identify poor prognostic factors.

Patients And Methods: In this multi-center retrospective study, we analyzed the data of patients with CCC between February 2012 and December 2020.

Public support for patients with intractable diseases in Japan: impact on clinical indicators from nationwide registries in patients with autosomal dominant polycystic kidney disease.

Background: Clinical practice guidelines recommend antihypertensive and tolvaptan therapies for patients with autosomal dominant polycystic kidney disease (ADPKD) in Japan. However, tolvaptan therapy may pose an economic burden. The Japanese Ministry of Health, Labour and Welfare supports patients with intractable diseases.

Efficacy of Endoscopic Resection for Rectal Neuroendocrine Tumors Smaller than 15 mm.

Background: Local resection, including endoscopic resection, is recommended for rectal neuroendocrine tumors (NETs) < 15 mm in patients without risk factors for metastasis, though the short- and long-term outcomes are unclear.

Aims: This study investigates the efficacy of endoscopic resection for rectal NETs < 15 mm.

Methods: The short- and long-term outcomes of patients with rectal NETs < 15 mm who underwent endoscopic resection and the outcomes of each endoscopic technique were analyzed.

Central sensitization as a predictive factor for the surgical outcome in patients with lumbar spinal stenosis: a multicenter prospective study.

Purpose: The impact of central sensitization (CS) on neurological symptoms and surgical outcomes in patients with lumbar spinal stenosis (LSS) remains unknown. This study aimed to investigate the influence of preoperative CS on the surgical outcomes of patients with LSS.

Methods: A total of 197 consecutive patients with LSS (mean age 69.

Multicenter retrospective study of the prognosis and the effect of postoperative adjuvant therapy in Japanese oral squamous cell carcinoma patients with close margin.

Background: The purpose of this retrospective study was to investigate the prognosis of patients with oral cavity cancer with positive margin (PM) or close margin (CM) divided into pN- and pN+ groups.

Methods: The evaluated endpoints were local control and disease-specific survival (DSS) rates.

Results: Higher T classification, lymphovascular space invasion (LVSI), and older age were significant risk factors for DSS in the pN- groups.

Mutation Analysis of Autosomal-Dominant Polycystic Kidney Disease Patients.

Autosomal-dominant polycystic kidney disease (ADPKD) is characterized by bilateral kidney cysts that ultimately lead to end-stage kidney disease. While the major causative genes of ADPKD are and , other genes are also thought to be involved. Fifty ADPKD patients were analyzed by exome sequencing or multiplex ligation-dependent probe amplification (MLPA), followed by long polymerase chain reaction and Sanger sequencing.

Sporadic Myotonic Dystrophy Type 2 in a Japanese Patient.

We herein report a Japanese patient with myotonic dystrophy type 2 (DM2), which is rare in Japan. A 64-year-oldman had proximal muscle weakness and grip myotonia. Electromyography showed myotonic discharges, but dystrophia-myotonica protein kinase (DMPK) was negative for CTG repeats.
