Gait Acquisition with a Quadrilateral Socket after Ultra-short Transfemoral Amputation because of Staphylococcal Toxic Shock Syndrome.

Background: Streptococcal toxic shock syndrome (STSS) is a notifiable disease under Japan's Infectious Disease Control Law and has become a pandemic following COVID-19. STSS often leads to necrotizing fasciitis, with a mortality rate exceeding 30%. Even in surviving patients, limb amputations are common.

Repertoire analysis of memory T-cell receptors in Japanese patients with inflammatory bowel disease.

Background And Aim: The T-cell receptor (TCR) repertoire was assessed in response to various antigens and was considered to be associated with the pathogenesis of inflammatory bowel disease (IBD). Thus, we performed TCR repertoire analysis to examine the pathology of IBD from changes in the TCR repertoire of memory T cells in the intestinal lamina propria mononuclear cells (LPMCs) and peripheral blood mononuclear cells (PBMCs) of patients with IBD.

Methods: LPMCs in the surgical specimens and PBMCs were isolated from 12 patients with IBD (5 patients with ulcerative colitis [UC] and 7 patients with Crohn's disease [CD]).

An Integrated Genomic and Transcriptomic Analysis Reveals Candidates of Susceptibility Genes for Crohn's Disease in Japanese Populations.

Expression quantitative trait locus (eQTL) analyses have enabled us to predict the function of disease susceptibility SNPs. However, eQTL for the effector memory T cells (TEM) located in the lamina propria mononuclear cells (LPMCs), which play an important role in Crohn's disease (CD), are not yet available. Thus, we conducted RNA sequencing and eQTL analyses of TEM cells located in the LPMCs from IBD patients (n = 20).

Genetic Analysis of Ulcerative Colitis in Japanese Individuals Using Population-specific SNP Array.

Background: To clarify the genetic background of ulcerative colitis (UC) in the Japanese population, we conducted a genome-wide association study (GWAS) using a population-specific single nucleotide polymorphism (SNP) array.

Methods: We performed a GWAS and replication study including 1676 UC patients and 2381 healthy controls. The probability of colectomy was compared between genotypes of rs117506082, the top hit SNP at HLA loci, by the Kaplan-Meier method.

Correction to: High-resolution melt analysis enables simple genotyping of complicated polymorphisms of codon 18 rendering the NUDT15 diplotype.
