Hodgkin and Reed-Sternberg (HRS) cells, a hallmark of classic Hodgkin lymphoma (CHL), are occasionally detected in non-Hodgkin lymphomas, including adult T-cell leukemia/lymphoma (ATLL), a lymphoid neoplasm caused by human T-cell leukemia virus type 1 (HTLV-1). HRS-like cells associated with ATLL have been described to be of B-cell lineage and infected with Epstein-Barr virus (EBV), not HTLV-1. We herein describe clinicopathological findings in 8 cases (4 males and 4 females; median age, 73 years [range, 55-81 years]) of ATLL with HTLV-1-infected HRS-like cells identified by ultrasensitive RNA in situ hybridization for HTLV-1 basic leucine zipper factor (HBZ-ISH), a specific viral transcript of HTLV-1.

The purpose of this study was to clarify the natural history of unruptured visceral artery aneurysms due to segmental arterial mediolysis and the efficacy of transcatheter arterial embolization. Patients with a pathologic or clinical diagnosis of visceral artery aneurysms due to segmental arterial mediolysis between 2005 and 2015 were enrolled. For patients with clinical diagnoses, images were collected and assessed by central radiologic review.

Article Synopsis
  • - The study investigates genetic changes in adult T-cell leukemia/lymphoma (ATLL) among 89 Okinawan patients, revealing that they have similar mutation profiles to mainland Japanese patients but show distinct variations compared to North American cases.
  • - Okinawan patients frequently exhibit specific mutations (e.g., GATA3 and RHOA) linked to the higher prevalence of the HTLV-1-taxA viral strain, suggesting that this strain may influence mutation rates differently than HTLV-1-taxB found in mainland Japan.
  • - Clinically, the research highlights the negative impact of certain genetic alterations on patient outcomes and emphasizes the need for regional considerations in developing effective therapies for ATLL.

  • The study aimed to explore the link between irregular menstrual cycles and night shift frequency among Japanese female nurses, highlighting a gap in existing research.
  • A survey of 1,249 women revealed that 24.8% of those without night shifts and over 35% of those on two or three rotating shifts experienced irregular cycles.
  • Results showed a dose-response relationship for irregular cycles with night shift frequency, especially in those on two rotating shifts, while the risk of menstrual discomfort increased significantly for those on three rotating shifts.

Introduction: The short-term survival rate after single-stage correction of Taussig-Bing anomaly with aortic arch obstruction remains favorable. However, some cases are encountered occasionally in which single-stage correction was not performed during the neonatal period. Accordingly, we evaluated the midterm outcomes of different surgical strategies.

Childhood, adolescent, and young adult (CAYA) cancer survivors may be at risk for a severe course of COVID-19. Little is known about the clinical course of COVID-19 in CAYA cancer survivors, or if additional preventive measures are warranted. We established a working group within the International Late Effects of Childhood Cancer Guideline Harmonization Group (IGHG) to summarize existing evidence and worldwide recommendations regarding evidence about factors/conditions associated with risk for a severe course of COVID-19 in CAYA cancer survivors, and to develop a consensus statement to provide guidance for healthcare practitioners and CAYA cancer survivors regarding COVID-19.

Although cases with metachronous or synchronous co-occurrence of classic Hodgkin lymphoma (CHL) and B-cell non-Hodgkin lymphoma (B-NHL) have been reported, few reports have analyzed the clonal relationship between both lesions in detail, especially in Epstein-Barr virus (EBV)-positive settings. Here, we report a case of a 38-year-old male with CHL, followed by the recurrence of EBV-positive mucocutaneous ulcers of the large intestine and EBV-positive diffuse large B-cell lymphoma in the liver. Surprisingly, polymerase chain reaction analysis for immunoglobulin heavy chain gene rearrangement revealed that all lesions were clonally distinct.

Histopathological distinction between adult T-cell leukemia/lymphoma (ATLL) and other T-cell neoplasms is often challenging. The current gold standard for the accurate diagnosis of ATLL is the Southern blot hybridization (SBH) assay, which detects clonal integration of human T-cell leukemia virus type I (HTLV-1) provirus. However, SBH cannot be performed with small biopsy or formalin-fixed paraffin-embedded (FFPE) tissue samples because this assay requires a large amount of DNA without degradation.

Although Turner syndrome (TS) is frequently associated with congenital anomalies of the kidney-urinary tract (CAKUT), which is a major cause of pediatric chronic kidney disease, renal function in TS is usually considered normal. The present study aimed to analyze the frequency of renal dysfunction and CAKUT in pediatric patients with TS. Our study included 122 patients with TS between the ages of 2 and 18 years from 30 hospitals across Japan.

X-linked Alport syndrome (XLAS) is a progressive hereditary kidney disease caused by mutations in the COL4A5 gene encoding the type IV collagen α5 chain. To date, 11 cases having somatic mosaic variants in COL4A5 have been reported; however, all of them involved single-nucleotide variations (SNVs). Here, we report a female XLAS patient with somatic mosaicism identified by copy number variation (CNV) in COL4A5.

Aim: To investigate the new risk factors for keloid recurrence after postoperative electron beam radiotherapy (RT) and evaluate the effectiveness of tranilast in combination with electron beam RT by comparing the local control rate.

Background: Identifying patients at high risk of recurrence after postoperative RT for keloids remains a challenge. Besides, no study examined the effectiveness of tranilast in combination with RT after surgery for the prevention of keloids recurrence.

Carnitine-acylcarnitine translocase (CACT) deficiency is a fatty acid ß-oxidation disorder of the carnitine shuttle in mitochondria, with a high mortality rate in childhood. We evaluated three patients, including two siblings, with neonatal-onset CACT deficiency and revealed identical homozygous missense mutations of p.Arg275Gln within the gene.

Osimertinib has demonstrated efficacy against stable or asymptomatic central nervous system (CNS) metastases of epidermal growth factor receptor () mutation-positive non-small-cell lung cancer (NSCLC) in phase 2 and 3 clinical trials that allowed prior CNS radiotherapy. However, the efficacy of osimertinib only or the optimal treatment combination or sequence of radiotherapy has not been investigated.

  • Immune-mediated thrombotic thrombocytopenic purpura (iTTP) is an autoimmune disorder linked to specific HLA alleles, with different associations found in white individuals compared to Japanese individuals.
  • In a study of 52 Japanese iTTP patients, several HLA alleles were identified as predisposing factors, including DRB1*08:03, DRB3/4/5*blank, DQA1*01:03, and DQB1*06:01, which were significantly more frequent in iTTP patients than in controls.
  • The research concluded that the genetic factors influencing iTTP vary between populations, highlighting the unique role of certain HLA alleles in Japanese patients

Anti-complement factor H (CFH) autoantibody (Ab)-associated atypical hemolytic uremic syndrome (aHUS) has a poor prognosis in terms of frequent relapses. Although eculizumab is an effective treatment for this type of aHUS, the method of eculizumab discontinuation is not yet established. Herein, we report a case of anti-CFH Ab-associated aHUS in a 6-year-old boy.

  • The study aims to evaluate different diagnostic methods for detecting Clostridioides difficile infection (CDI) in patients with significant diarrhea across 12 medical facilities in Japan, comparing them to the gold standard of toxigenic culture (TC).
  • Key findings indicated that nucleic acid amplification tests (NAAT) showed higher sensitivity (74%) compared to enzyme immunoassays (EIA) (41%) and performed similarly to the GDH algorithm (71%).
  • Overall, NAAT and the GDH algorithm demonstrated good negative predictive values (92% and 91%, respectively) but highlighted the complexity of choosing the optimal diagnostic approach amid varying performance metrics for CDI detection.
