To validate the usefulness of a hepatic fibrosis scoring system fibrosis-4 (FIB-4) index to diagnose liver diseases in rheumatoid arthritis (RA) patients treated with methotrexate (MTX). The FIB-4 index (age(years) × AST(U/L)/platelet (PLT) (10/L) × √ALT(U/L)), proposed as a predictor for liver fibrosis in HIV/HCV coinfection, was evaluated in this study. RA patients on MTX treatment were screened by FIB-4 index values to detect fibrotic change in the liver.

Background: Activated phosphatidylinositol-3-OH kinase δ syndrome type 1 (APDS1) is a recently described primary immunodeficiency syndrome characterized by recurrent respiratory tract infections, lymphoid hyperplasia, and Herpesviridae infections caused by germline gain-of-function mutations of PIK3CD. Hematopoietic stem cell transplantation (HSCT) can be considered to ameliorate progressive immunodeficiency and associated malignancy, but appropriate indications, methods, and outcomes of HSCT for APDS1 remain undefined.

Objective: Our objective was to analyze the clinical manifestations, laboratory findings, prognosis, and treatment of APDS1 and explore appropriate indications and methods of HSCT.

Background: Ganglioneuroblastoma, nodular is defined as a composite tumor of biologically distinct clones. The peripheral neuroblastic tumors in this category are characterized by the presence of grossly visible neuroblastoma nodules coexisting with ganglioneuroblastoma, intermixed, or with ganglioneuroma. Making a correct diagnosis of ganglioneuroblastoma, nodular is often difficult by biopsy or partial tumor resection, because the neuroblastic nodule could be hidden and not sampled for pathological examination.

We herein report a 74-year-old woman who presented with autoimmune hemolytic anemia (AIHA) associated with pleural solitary fibrous tumor (SFT). Her AIHA was initially treated with 1 mg/kg daily of oral prednisolone (PSL) for 2 months, which had a limited effect. However, after surgical tumor resection, the patient showed remarkable improvement of AIHA with normalizations of serum lactate dehydrogenase and bilirubin levels, and we were able to rapidly reduce the PSL dosage.

Unlabelled: We describe a case of giant cell tumor of the proximal tibia with skip bone metastases of the ipsilateral femur in a 20-year-old man. After the neoadjuvant treatment with denosumab, plain radiographs and computed tomography showed marked osteosclerosis and sclerotic rim formation, and 18F-FDG PET/CT showed a decreased standardized uptake value, whereas magnetic resonance imaging showed diffuse enhancement of the tumor, nearly the same findings as those at pretreatment. Pathological findings of the surgical specimen after the denosumab treatment showed benign fibrous histiocytoma-like features with complete disappearance of both mononuclear stromal cells and multinuclear osteoclast-like giant cells.

Article Synopsis
  • MCP-1 enhances the progression of ovarian cancer by increasing the invasion and adhesion of SKOV-3 cells, a type of ovarian cancer cell line.
  • Experiments showed that treating SKOV-3 cells with MCP-1 significantly boosted their migration and attachment compared to untreated cells, with CCR2 playing a key role in this process.
  • The findings suggest that targeting MCP-1 could offer a new therapeutic approach for treating ovarian cancer, as blocking its receptor CCR2 reduced the aggressive behavior of the cancer cells.

Chronic lymphocytic leukemia (CLL) rarely exhibits an aggressive clinical course and its patients often have chromosomal deletions or additions. Furthermore, reciprocal translocations are barely observed in CLL. There have only been a few reports of CLL with t(1;6), and here we report the first Asian case of CLL with reciprocal translocation t(1;6).

Introduction: A prior study with 22-gauge needles recommended more than seven needle passes for endoscopic ultrasound-guided fine-needle aspiration biopsy (EUS-FNA) of solid pancreatic lesions (SPL) without onsite cytopathology for optimal acquisition of cytopathological diagnosis. The feasibility of this recommendation should be re-evaluated considering the later development and popularity of 25-gauge EUS-FNA needles. We aimed to determine the optimal number of needle passes for cytopathological specimen acquisition with 25-gauge needles for EUS-FNA of SPL.

Recently, it was reported that ependymoblastoma and embryonal tumor with abundant neuropil and true rosettes (ETANTR) show 19q13.42 amplification at a high frequency, suggesting that these tumors may constitute a single entity. As ependymoblastic rosettes are the most prominent features in both subtypes, embryonal tumor with multilayered rosettes (ETMR) was proposed, for which 19q13.

Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the gastrointestinal tract that are diagnosed by c-kit staining in most cases. A lysosomal cysteine proteinase termed cathepsin L has been commonly associated with malignancy in several cancer types, but this finding has not been reported for GISTs. We analyzed the cathepsin L mRNA and protein expression in GISTs.

Idiopathic normal pressure hydrocephalus (iNPH) is an elderly dementia caused by abnormal metabolism in the cerebrospinal fluid (CSF). The tap test is the current basis for confirming iNPH, but it shows very low sensitivity, indicating that many patients who might be cured by a shunt operation will be missed. On sodium dodecyl sulfate-polyacrylamide gel electrophoresis, we found two transferrin isoforms: one had a unique N-glycan (Tf-1) whereas the other had N-glycan similar to that of serum transferrin (Tf-2).
