Prolonged severe cytopenia followed by fatal CAR T-cell-mediated encephalitis in a patient with acute lymphoblastic leukemia.

Immune effector cell-associated neurotoxicity syndrome usually occurs within the first four weeks of chimeric antigen receptor (CAR)-T cell therapy. In addition, prolonged cytopenia is a long-term adverse effect following the use of CAR T-cell therapies. Here, we present a case of prolonged severe cytopenia followed by fatal CAR T-cell-mediated encephalitis.

A Rare Case of Cocklebur Foreign Body in the Larynx.

Plant foreign matter in the larynx is rare. Only three cases of a cocklebur foreign body in the larynx have been previously reported. A 55-year-old man accidentally swallowed cocklebur fruit.

Efficacy of Vinblastine and Methotrexate in a Childhood Patient with Progressive Desmoid Fibromatosis of the Lower Jaw: A Case Report.

Desmoid fibromatosis (DF) is defined as a borderline tumor of the soft tissues with a low malignant potential. The most common tumor sites are the extremity, trunk, abdominal cavity, and head and neck. Surgical resection has been the standard treatment for DF.

Endoscopic Approach to Postoperative Maxillary Cysts Ensuring Infraorbital Nerve Safety With Direct Approach to the Anterior and Lateral Part of the Maxillary Sinus With an Endoscope (DALMA): A Case Report.

Postoperative maxillary cysts (POMCs) present significant challenges, especially when located laterally or when the infraorbital nerve's course is unclear on imaging. Traditional endoscopic approaches are often limited by a high risk of recurrence and potential nerve injury. Here, we report a case of a 72-year-old woman with a right maxillary cyst, which caused pain and swelling.

Allogeneic stem cell transplantation for inherited metabolic disorders: 35 years' experience at a single institution.

Hematopoietic stem cell transplants for inherited metabolic disorders performed at Tokai University Hospital between June 5, 1986, and May 28, 2021, were analyzed and compared between the period before 2007 and the period from 2007 onward based on availability of medical resources. Transplants were performed for 38 patients with mucopolysaccharidosis, 33 with adrenoleukodystrophy, and 16 with another disorder. Before 2007, oral busulfan-based regimens were mainly used.

Assessment of eosinophilic rhinosinusitis cases that required secondary treatment (biologics or reoperation) during long-term postoperative courses.

Objective: Endoscopic sinus surgery (ESS) is selected as the primary treatment for eosinophilic chronic rhinosinusitis (ECRS). Biologics or reoperation are sometimes required as secondary treatment after ESS. The present study examined the long-term postoperative courses of ECRS cases treated according to the current treatment concept, the frequency of secondary treatment, and its predictive factors.

Retrospective evaluation of the improvement in the urinary status-related quality of life after robot-assisted radical prostatectomy.

Objectives: This study aimed to investigate the characteristics of patients who report improvement in quality of life (QOL) related to urinary status after undergoing robot-assisted radical prostatectomy (RARP) for localized prostate cancer.

Methods: We retrospectively reviewed the patients who underwent RARP between May 2010 and May 2021 at our institution and were preoperatively unsatisfied with their urinary status. Patients were grouped as Group 1 (improved patients: "satisfied" with urinary status based on international prostate symptom score QOL [IPSS-QOL] = 0-2 at 12 months after RARP) and Group 2 (unimproved group: "unsatisfied"-IPSS-QOL 3-6).

[LOWER RESPIRATORY TRACT SCREENING USING FRACTIONAL EXHALED NITRIC OXIDE IN PATIENTS WITH EOSINOPHILIC CHRONIC RHINOSINUSITIS].

Background: It is known that eosinophilic chronic rhinosinusitis is often associated with adult-onset bronchial asthma, and undiagnosed bronchial asthma is also known to be included. The purpose of this study is to screen patients with eosinophilic chronic rhinosinusitis using fractional exhaled nitric oxide, and to examine its usefulness in detecting undiagnosed bronchial asthma.

Methods: We retrospectively examined the data of patients with eosinophilic chrnoic rhinosinusitis who underwent surgical treatment at Kagawa University from April 2015 to July 2022.

A Boy Presenting with a Fever and Pancytopenia Diagnosed with Systemic Lupus Erythematosus without a Positive Anti-ds-DNA Antibody Result or Hypocomplementemia: A Case Report.

Background: Hematological involvement, including anemia, leukopenia, lymphopenia, and thrombocytopenia, is one of the most common manifestations of childhood-onset systemic lupus erythematosus (cSLE). Specifically, relatively severe forms of hematological involvement, such as macrophage activation syndrome (MAS) and thrombotic microangiopathy, occur in the course of the disease. Positivity for anti-double stranded-DNA (ds-DNA) antibody and hypocomplementemia are important as not only criteria of diagnosing cSLE but also in the determination of the disease activity.

Invasive Pulmonary Aspergillosis Successfully Treated with Granulocyte Transfusions Followed by Hematopoietic Stem Cell Transplantation in a Patient with Severe Childhood Aplastic Anemia.

Granulocyte transfusions (GTX) have been used in patients with neutropenia or neutropenia associated with invasive fungal infection. An 11-year-old girl with severe aplastic anemia (SAA) received immunosuppressive therapy (IST) with rabbit antithymocyte globulin, cyclosporine, and granulocyte colony-stimulating factor. However, IST was not effective and her condition became complicated with life-threatening invasive pulmonary aspergillosis.

Breath sound analyses of infants with respiratory syncytial virus acute bronchiolitis.

Introduction: The reliability of a breath sound analysis using an objective method in infants has been reported.

Objective: Breath sounds of infants with respiratory syncytial virus (RSV) acute bronchiolitis were analyzed via a breath sound spectrogram to evaluate their characteristics and examine their relationship with the severity.

Subjects And Methods: We evaluated the inspiratory and expiratory breath sound parameters of 33 infants diagnosed with RSV acute bronchiolitis.

A highly specific recurrent pleomorphic adenoma of the nasal septum.

A 90-year-old woman presented with the sudden onset of visual loss. She previously underwent surgery to treat a right septal pleomorphic adenoma (PA) at 77 years old. She initially presented to our hospital with severe nasal obstruction at 83 years old.

Early postoperative endoscopic score can predict the long-term endoscopic outcomes in eosinophilic chronic rhinosinusitis (ECRS) patients.

Objective: Eosinophilic Chronic Rhinosinusitis (ECRS) is refractory and recurrent, requiring long-term follow-up after Endoscopic Sinus Surgery (ESS). Endoscopic evaluation is common during postoperative assessment, but how the findings vary over time in postoperative ECRS patients who were treated by the recent standardized management is unclear. We assessed the long-term change in postoperative endoscopic score in ECRS patients using a novel endoscopic scoring system (Escore).

Novel antiangiogenic therapy targeting biglycan using tumor endothelial cell-specific liposomal siRNA delivery system.

Tumor blood vessels play important roles in tumor progression and metastasis. Targeting tumor endothelial cells (TECs) is one of the strategies for cancer therapy. We previously reported that biglycan, a small leucine-rich proteoglycan, is highly expressed in TECs.

Gradually progressive cholangiolocellular carcinoma: a case report.

Background: Cholangiolocellular carcinoma (CoCC) is a relatively rare primary liver tumor. We present a literature review and case report of a patient who presented with a slow-growing CoCC that was completely resected after a 5-year follow-up period.

Case Presentation: The patient was a 66-year-old man with a history of inflammatory thoracic and intra-abdominal pseudo-tumors.

miRNA-1246 in extracellular vesicles secreted from metastatic tumor induces drug resistance in tumor endothelial cells.

Tumor endothelial cells (TECs) reportedly exhibit altered phenotypes. We have demonstrated that TECs acquire drug resistance with the upregulation of P-glycoprotein (P-gp, ABCB1), contrary to traditional assumptions. Furthermore, P-gp expression was higher in TECs of highly metastatic tumors than in those of low metastatic tumors.

Successful combination chemotherapy involving clofarabine, cyclophosphamide, and etoposide for pediatric relapsed acute myeloid leukemia: A case report.

Limited salvage chemotherapies are available for relapsed/refractory acute myeloid leukemia. Herein, we described successful reinduction chemotherapy, involving a combination of clofarabine, cyclophosphamide, and etoposide, in a 12-year-old male with relapsed acute myeloid leukemia prior to allogeneic bone marrow transplantation from his father. Although treatment with a combination of fludarabine, cytarabine, granulocyte colony-stimulating factor, idarubicin, and gemtuzumab ozogamicin had no positive effects, the aforementioned clofarabine-based chemotherapy induced complete remission and allowed the transplantation to go ahead.

Anticoagulation treatment and prophylactic edoxaban for cerebral sinus venous thrombosis in an adolescent with acute lymphoblastic leukemia.

Pediatric acute lymphoblastic leukemia regimens include large L-asparaginase dosages and steroids, which are associated with an increased risk of venous thromboemboli in adolescents and young adults. Herein, we report the case of an 18-year-old male with acute lymphoblastic leukemia, who was treated with the pediatric regimen, in which edoxaban was employed as a prophylaxis against cerebral sinus venous thrombosis. The event happened on day 20 of induction therapy, when brain magnetic resonance imaging demonstrated a cerebral sinus venous thrombosis in the superior sagittal sinus.
