infection successfully treated with oral administration of minocycline and thermotherapy.

We report a case of a woman presenting with an erythematous finger nodule, with a history of exposure to tropical fish. The erythematous nodules subsequently spread proximally from the finger. Initial treatment with oral amoxicillin-clavulanate was unsuccessful, and she developed a drug eruption.

Early failure is still a poor prognostic factor in patients with relapsed or refractory large B-cell lymphoma in the era of CAR T-cell therapy.

Patients with refractory or relapsed (R/R) large B-cell lymphoma (LBCL) refractory to first-line chemotherapy or with early relapse have poor outcomes. While chimeric antigen receptor (CAR) T-cell therapy has impressive efficacy after two or more lines of chemotherapy, it's still uncertain if these outcomes remain consistent in the context of third-line CAR T-cell therapy. We conducted a retrospective study of 107 R/R LBCL patients.

Material And Methods: A retrospective study was conducted of 32 MD patients and 2 DEH patients treated by MEPT with the EFET01 device from December 2018 to April 2021.

Clinical outcomes in transplant-eligible patients with relapsed or refractory diffuse large B-cell lymphoma after second-line salvage chemotherapy: A retrospective study.

Objective: The prognosis of patients with relapsed or refractory (R/R) diffuse large B-cell lymphoma (DLBCL) is poor. Although patients who fail first-line salvage chemotherapy are candidates for second-line salvage chemotherapy, the optimal treatment strategy for these patients has not yet been established.

Methods: The present, single-center, retrospective study included transplant-eligible patients with R/R DLBCL who received second-line salvage chemotherapy with curative intent.

Hemoglobin-platelet index as a prognostic factor in patients with peripheral T-cell lymphoma.

Peripheral T-cell lymphoma (PTCL) is a heterogeneous group of aggressive lymphomas with a poor prognosis. The International Prognostic Index (IPI) and the Prognostic Index for PTCL-unspecified (PIT) is used to predict the prognosis of PTCL. The hemoglobin-platelet index (HPI), based on anemia and thrombocytopenia status, is associated with the prognosis of diffuse large B-cell lymphoma.

Changes in functional connectivity among vestibulo-visuo-somatosensory and spatial cognitive cortical areas in persistent postural-perceptual dizziness: resting-state fMRI studies before and after visual stimulation.

Introduction: Persistent postural-perceptual dizziness (PPPD) is a functional chronic vestibular syndrome with symptom exacerbation by upright posture, motion, and complex visual stimuli. Among these exacerbating factors, visual exacerbation is the most specific characteristic of PPPD requiring further investigation. We hypothesized that stimulus-induced changes occur in the functional connectivity (FC) rather than simple neural activation that is involved in visual stimulation.

[Polatuzumab vedotin, bendamustine, and rituximab in patients with relapsed/refractory diffuse large B-cell lymphoma, including the outcome as a bridging treatment to CAR-T cell therapy or allogeneic hematopoietic stem cell transplant].

Pola-BR (polatuzumab vedotin, bendamustine, and rituximab) therapy received approval for relapsed/refractory diffuse large B-cell lymphoma (R/R DLBCL) in Japan in March 2021. There have been few reports on the efficacy and safety of Pola-BR therapy in Japanese clinical practice. A retrospective analysis was performed on twenty-nine patients with R/R DLBCL who received Pola-BR therapy at our institution (intent to cellular immunotherapy cohort: 20 patients, stand-alone treatment cohort: nine patients).

Utility of the frailty score for predicting prognosis and individualizing treatment intensity in elderly patients with diffuse large B cell lymphoma.

The optimal dose intensity of chemotherapy for elderly patients with diffuse large B cell lymphoma (DLBCL) remains controversial because of concerns about adverse events and comorbidities related to the patients' frailty. This single-center study retrospectively analyzed patients aged ≥ 70 years who were newly diagnosed with DLBCL and received chemotherapy between 2004 and 2022. Survival outcomes and treatment-related mortality (TRM) were stratified according to geriatric assessment variables, and the influence of chemotherapy dose intensity on outcomes was assessed using the frailty score with a Cox hazards model with restricted cubic spline (RCS) in patients aged 70-79 years.

[Determination of Chlorothalonil Metabolite I in Livestock Products by LC-MS/MS].

An analytical method based on LC-MS/MS was developed for the determination of chlorothalonil metabolite I in livestock products. Chlorothalonil metabolite I in livestock products was extracted with acetone. The crude extracts were defatted by acetonitrile and n-hexane partitioning.

Gaze instability after exposure to moving visual stimuli in patients with persistent postural-perceptual dizziness.

Introduction: Persistent postural-perceptual dizziness (PPPD) is a chronic vestibular syndrome lasting more than 3 months. The core vestibular symptoms are dizziness, unsteadiness, and non-spinning vertigo, which are exacerbated by upright posture or walking, active or passive motion, and exposure to moving or complex visual stimuli. Among these, visual exacerbation is a key feature of PPPD for which the neural mechanisms are unknown.

Locations and Predictive Factors of Hypertrophic Pachymeningitis in Otitis Media With Antineutrophil Cytoplasmic Antigen-Associated Vasculitis.

Study Design: Retrospective study.

Setting: University hospital.

Optimal Diagnostic Criteria and a Staging System for Otogenic Skull Base Osteomyelitis.

 Diagnostic criteria for otogenic skull base osteomyelitis (SBO) have been conflicting among researchers. We aimed to propose clinically useful diagnostic criteria and a staging system for otogenic SBO that is associated with infection control and mortality.  The present study is designed as a retrospective one.

Synchronous multiple primary tumors in patients with malignant lymphoma: a retrospective study.

Background: Synchronous multiple primary malignant tumors (sMPMTs) are sometimes diagnosed in patients with malignant lymphoma. We herein investigated the prognostic impact of sMPMT in lymphoma patients and the optimal treatment strategy.

Methods: Seventy-five patients with sMPMTs (5.

A sheet pocket to prevent cross-contamination of formalin-fixed paraffin-embedded block for application in next generation sequencing.

Formalin-fixed paraffin-embedded (FFPE) blocks are used as biomaterials for next-generation sequencing of cancer panels. Cross-contamination is detected in approximately 5% of the DNA extracted from FFPE samples, which reduces the detection rate of genetic abnormalities. There are no effective methods available for processing FFPE blocks that prevent cells from mixing with other specimens.

Impact of pegfilgrastim approval on relative dose intensity and outcomes of R-CHOP for diffuse large B-cell lymphoma.

Maintaining relative dose intensity (RDI) of rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) improves the prognosis of patients with diffuse large B-cell lymphoma (DLBCL). Pegfilgrastim was approved in Japan in November 2014 to prevent febrile neutropenia (FN) and maintain RDI.In this retrospective study, we reviewed 334 patients with DLBCL who received 6 or more courses of R-CHOP and analyzed the differences in the RDI, overall survival (OS), and progression-free survival between patients whose treatment started after November 2014 (postapproval group) and those whose treatment started before October 2014 (pre-approval group).

Effects of sound source localization of masking sound on perception level of simulated tinnitus.

Tinnitus therapies have been combined with the use of varieties of sound/noise. For masking external sounds, location of the masker in space is important; however, effects of the spatial location of the masker on tinnitus are less understood. We aimed to test whether a masking sound location would affect the perception level of simulated tinnitus.

Chimeric antigen receptor T-cell therapy following autologous transplantation for secondary central nervous system lymphoma: A case report.

Rationale: Chimeric antigen receptor (CAR) T-cell therapy is effective in treating relapsed and refractory B-cell non-Hodgkin lymphoma. However, because of the mortality risk associated with immune effector cell-associated neurotoxicity syndrome and pseudoprogression, patients with central nervous system (CNS) involvement are less likely to receive CAR T-cell therapy.

Patients Concerns: We report a case of a 61-year-old, male patient with intravascular large B-cell lymphoma who suffered a CNS relapse after standard chemotherapy.

Test Batteries and the Diagnostic Algorithm for Chronic Vestibular Syndromes.

To develop a diagnostic algorithm for chronic vestibular syndromes by determining significant items that differ among diagnoses. Two hundred thirty-one patients with chronic vestibular syndromes lasting for >3 months were included. Full vestibular tests and questionnaire surveys were performed: bithermal caloric test, cervical and ocular vestibular-evoked myogenic potential assessment, video head impulse test (vHIT), posturography, rotatory chair test, dizziness handicap inventory, hospital anxiety and depression scale (HADS), and Niigata persistent postural-perceptual dizziness (PPPD) questionnaire (NPQ).

Lemierre's Syndrome Due to Malignant Otitis Externa: Imaging Studies Revealed Its Systemic Dissemination.

Lemierre's syndrome is characterized by internal jugular vein thrombosis and systemic septic embolism; it is a fatal complication of upper respiratory tract infections. To date, it has not been demonstrated how the upper respiratory tract inflammation spreads from the primary infection site to internal jugular vein and systemic thrombosis. We report a very rare case of Lemierre's syndrome derived from malignant otitis externa in which the spread of infection and thrombosis process were identified by imaging.
