Successful maintenance therapy with tocilizumab for severe acute liver failure associated with adult-onset still's disease.

Elevated liver enzymes are commonly observed among adult-onset Still's disease (AOSD), but severe acute liver failure is extremely rare. Although severe acute liver failure associated with AOSD poses a life-threatening condition, the appropriate treatment is unclear. Some case reports have demonstrated the efficacy of high-dose prednisolone (PSL) and cyclosporin A (CyA), although the adverse effects of CyA led certain patients to cease its use.

In-depth proteomics reveals the characteristic developmental profiles of early lung adenocarcinoma with epidermal growth factor receptor mutation.

Introduction: Lung adenocarcinoma progresses stepwise from atypical adenomatous hyperplasia to adenocarcinoma in situ (AIS), followed by minimally invasive adenocarcinoma (MIA), and then obvious invasive adenocarcinoma. In this study, we examined the protein expression profiles of early and epidermal growth factor receptor (EGFR) mutation-positive lung adenocarcinomas.

Methods: Fifteen cases of small and EGFR mutation-positive adenocarcinomas were collected, including AIS, MIA, and small invasive adenocarcinoma (SIA).

Usefulness of malignant pleural effusion for early cytological diagnosis of mesothelioma : A case report.

Mesothelioma (MIS) is defined as a preinvasive mesothelioma that forms a single layer of mild atypical mesothelial cells lining on the serosa surface of pleura. The atypical mesothelial cells present loss of BRCA-1 associated protein-1 (BAP-1) and/or methylthioadenosine phosphorylase as examined by immunohistochemistry (IHC) and/or homozygous deletion of cyclin-dependent kinase inhibitor 2A/p16 as examined by fluorescence hybridization. It is difficult to diagnose because of the unremarkable clinical findings except for pleural effusion.

Impact of sleep-related hypoventilation in patients with pleuroparenchymal fibroelastosis.

Background: Pleuroparenchymal fibroelastosis (PPFE) is a rare fibrosing lung disease with a predilection for the upper lobe and its progression causes hypoventilation, resulting in hypercapnia. Even though the association between sleep-related hypoventilation (SRH) and chronic obstructive pulmonary disease was well documented, its impact in patients with PPFE was not evaluated. The aim of this study is to clarify the impact of SRH on prognosis in PPFE.

A Case of Pulmonary Metastasis of Breast Cancer 23 Years after Surgery Accompanied with Non-Tuberculous Mycobacterium Infection.

Recurrence of oestrogen receptor (ER)-positive breast cancer rarely occurs postoperatively after a long period. Breast cancer cells survive and settle in distant organs in a dormant state, a phenomenon known as "tumour dormancy." Here, we present a 66-year-old woman with recurrence of ER-positive breast cancer in the left lung 23 years after surgery accompanied with non-tuberculous mycobacterium infection (NTM).

A population-based study of outcomes in patients with surgically resected non-small cell lung cancer with anaplastic lymphoma kinase-rearranged mutations: A matched-pair study.

The present study aimed to evaluate clinical outcomes in patients with surgically resected non-small cell lung cancer (NSCLC) with anaplastic lymphoma kinase (ALK)-rearranged mutations. A matched-pair analysis in completely resected ALK-rearranged NSLC patients and those with neither ALK nor epidermal growth factor receptor (EGFR) mutations diagnosed at 11 institutes was performed between April 2008 and March 2019. A total of 51 patients with surgically resected ALK-rearranged NSCLC were included.

CLIF-C Organ Failure Score and Liver Volume Predict Prognosis in Steroid-Treated Severe Acute Autoimmune Hepatitis.

Controversies and debates remain regarding the best management of severe acute-onset autoimmune hepatitis (SA-AIH) due to the lack of useful outcome or complication prediction systems. We conducted this clinical practice-based observational study to clarify whether Chronic Liver Failure Consortium Organ Failure scores (CLIF-C OFs) and the computed tomography-derived liver volume to standard liver volume (CTLV/SLV) ratio at admission to a tertiary transplant center can predict outcomes and complications due to infection. Thirty-four consecutive corticosteroid-treated patients with SA-AIH from 2007 to 2018 were included.

A case of Marfan syndrome with massive haemoptysis from collaterals of the lateral thoracic artery.

Background: Marfan Syndrome (MFS) is a heritable connective tissue disorder with a high degree of clinical variability including respiratory diseases; a rare case of MFS with massive intrathoracic bleeding has been reported recently.

Case Presentation: A 32-year-old man who had been diagnosed with MFS underwent a Bentall operation with artificial valve replacement for aortic dissection and regurgitation of an aortic valve in 2012. Warfarin was started postoperatively, and the dosage was gradually increased until 2017, when the patient was transported to our hospital due to sudden massive haemoptysis.

Liver Fibrosis Markers Improve Prediction of Outcome in Non-Acetaminophen-Associated Acute Liver Failure.

A prognostic system for acute liver failure (ALF) with a higher predictive value is urgently needed. The role of extracellular matrix (ECM) remodeling in ALF has not been fully elucidated. We hypothesized that serologic fibrosis markers, which reflect ECM remodeling, are predictive of ALF outcome at first presentation.

Detection of bacterial DNA by in situ hybridization in patients with decompensated liver cirrhosis.

Background: Spontaneous bacterial peritonitis (SBP) is often difficult to diagnose because bacteria in ascites cannot be detected accurately by conventional culture. In situ hybridization (ISH) was previously developed for rapid detection of genes from bacteria phagocytized by neutrophils. SBP may develop after bacteria enter into the systemic circulation following bacterial translocation.

[CLINICAL UTILITY OF T-SPOT.TB ASSAY WITH T-Cell Xtend REAGENT FOR ACTIVE TUBERCULOSIS DIAGNOSIS IN THE FIELD TEST AT OUR HOSPITAL].

Background: T-SPOT.TB (T-SPOT), an interferon-gamma release assay, has shown promise as a diagnostic tool for active tuberculosis (TB), and its use is expanding. Addition of the T-Cell Xtend (TCX) reagent may allow delayed processing, and this characteristic is important for using this test in the field.

Dimethylarginine dimethylaminohydrolase 2 promotes tumor angiogenesis in lung adenocarcinoma.

Although embryonal proteins have been used as tumor marker, most are not useful for detection of early malignancy. In the present study, we developed mouse monoclonal antibodies against fetal lung of miniature swine, and screened them to find an embryonal protein that is produced at the early stage of malignancy, focusing on lung adenocarcinoma. We found an antibody clone that specifically stained stroma of lung adenocarcinoma.

Genotype-Associated Differential NKG2D Expression on CD56+CD3+ Lymphocytes Predicts Response to Pegylated-Interferon/Ribavirin Therapy in Chronic Hepatitis C.

Hepatitis C virus (HCV) genotype 1 infections are significantly more difficult to eradicate with PEG-IFN/ribavirin therapy, compared to HCV genotype 2. The aim of this work is to investigate the difference of immunological impairments underlying this phenomenon. Pre-treatment NKG2D expression on peripheral CD56+CD3+ lymphocytes and CD56+CD3- NK cells from cases of chronic hepatitis C were analyzed and assessed by treatment effect.

Beneficial effect of an omega-6 PUFA-rich diet in non-steroidal anti-inflammatory drug-induced mucosal damage in the murine small intestine.

Aim: To investigate the effect of a fat rich diet on non-steroidal anti-inflammatory drug (NSAID)-induced mucosal damage in the murine small intestine.

Methods: C57BL6 mice were fed 4 types of diets with or without indomethacin. One group was fed standard laboratory chow.

Pregnant woman with non-comatose autoimmune acute liver failure in the second trimester rescued using medical therapy: A case report.

We present the case of a 25-year-old woman at 16 weeks of gestation who presented with non-comatose autoimmune acute liver failure and was at high risk of developing fulminant hepatitis. Predictive formulas indicated a high probability of developing fulminant hepatitis. Unenhanced computed tomography showed marked hepatic atrophy and broadly heterogeneous hypoattenuating areas.

Modified bowel preparation regimen for use in second-generation colon capsule endoscopy in patients with ulcerative colitis.

Background And Aim: We have reported that second-generation colon capsule endoscopy (CCE-2) might be feasible for assessing the severity of mucosal inflammation in ulcerative colitis (UC). However, because of the low rate (69%) of complete evaluation of the colon and owing to inadequate cleansing. We believe that the method of bowel preparation could be improved by reducing volume.

Acyl-CoA:cholesterol acyltransferase 1 mediates liver fibrosis by regulating free cholesterol accumulation in hepatic stellate cells.

Background & Aims: Acyl-coenzyme A: cholesterol acyltransferase (ACAT) catalyzes the conversion of free cholesterol (FC) to cholesterol ester, which prevents excess accumulation of FC. We recently found that FC accumulation in hepatic stellate cells (HSCs) plays a role in progression of liver fibrosis, but the effect of ACAT1 on liver fibrosis has not been clarified. In this study, we aimed to define the role of ACAT1 in the pathogenesis of liver fibrosis.

ECT2 amplification and overexpression as a new prognostic biomarker for early-stage lung adenocarcinoma.

Genetic abnormality in early-stage lung adenocarcinoma was examined to search for new prognostic biomarkers. Six in situ lung adenocarcinomas and nine small but invasive adenocarcinomas were examined by array-comparative genomic hybridization, and candidate genes of interest were screened. To examine gene abnormalities, 83 cases of various types of lung carcinoma were examined by quantitative real-time genomic PCR and immunohistochemistry.

The influence of serum sodium concentration on prognosis in resected non-small cell lung cancer.

Background: Hyponatremia is the most common electrolyte disorder and is a negative prognostic factor in several kinds of cancer. However, few reports have referred to hyponatremia in non-small cell lung cancer (NSCLC). In the present study, the authors examined the influence of preoperative serum sodium concentration on survival in completely resected NSCLC.

Differences in the prognostic implications of vascular invasion between lung adenocarcinoma and squamous cell carcinoma.

Objectives: Vascular invasion (VI) has been accepted as a universally important prognostic factor for patients with lung carcinoma. However, the clinical significance of VI in each of the histological subtypes has been unclear. The aim of the present study was to investigate differences in the clinicopathological implications of VI between adenocarcinoma and squamous cell carcinoma.

Free cholesterol accumulation in hepatic stellate cells: mechanism of liver fibrosis aggravation in nonalcoholic steatohepatitis in mice.

Unlabelled: Although nonalcoholic steatohepatitis (NASH) is associated with hypercholesterolemia, the underlying mechanisms of this association have not been clarified. We aimed to elucidate the precise role of cholesterol in the pathophysiology of NASH. C57BL/6 mice were fed a control, high-cholesterol (HC), methionine-choline-deficient (MCD), or MCD+HC diet for 12 weeks or a control, HC, high-fat (HF), or HF+HC diet for 24 weeks.
