Analysis of 105 peripheral and central nervous system complications in 1062 monoclonal gammapathies draws attention to two types of phenomena. The possibility of pure neurological manifestations of IgM monoclonal gammapathies with macroglobulinorachia leads to discussion of their nosological position in relation to Waldenström's disease, Burkitt's lymphoma and Marek's disease. It is suggested that these cases should be reclassified under the heading "secreting neurolymphomatosis". Immunofluorescence and electron microscopy of 10 biopsies of the peripheral nerve showed deposits of monoclonal immunoglobulin whose function in determining peripheral neuropathies is discussed. The simultaneous presence of lymphoid infiltration, amyloid deposits and the monoclonal immunoglobulin (M component) suggests that this immunoglobulin could be the link between the cellular infiltrate secreting it and amyloid infiltration which would be the visible manifestation of it.

Background: Approval of proteasome inhibitors, immunomodulatory drugs, and anti-CD38 monoclonal antibodies (mAbs), such as daratumumab, has reshaped treatment patterns in patients with multiple myeloma (MM) in Japan. This retrospective study evaluated patient characteristics, treatment patterns, and trends in MM patients using Medical Data Vision, the largest electronic health records database in Japan with anonymous inpatient and outpatient health information.
Methods: Patients aged ≥18 years, with ≥2 records of an MM diagnostic and disease code and ≥1 record of MM treatment between 01 April 2008 and 30 June 2023 were included.

Aims: T1 mapping on cardiac magnetic resonance (CMR) imaging is useful for diagnosis and prognostication in patients with light-chain cardiac amyloidosis (AL-CA). We conducted this study to evaluate the performance of T1 mapping parameters, derived from artificial intelligence (AI)-automated segmentation, for detection of cardiac amyloidosis (CA) in patients with left ventricular hypertrophy (LVH) and their prognostic values in patients with AL-CA.
Methods And Results: A total of 300 consecutive patients who underwent CMR for differential diagnosis of LVH were analyzed.

Background: Autoimmune encephalitis associated with anti-GluK2 antibodies is a recently identified condition, typically characterized by cerebellar ataxia. This case report presents a unique clinical manifestation involving involuntary movements and emotional dysregulation, expanding the known phenotype spectrum.
Case Presentation: A 60-year-old woman presented with a two-year history of involuntary movements predominantly affecting her lower limbs and facial muscles, occasionally accompanied by hysterical shouting.

Peripheral nerve injury affects some people with multiple myeloma; this condition can be brought on by the disease itself or by the treatments they receive. Such a complication increases patients' financial burden, causes treatment to be interrupted or delayed, and reduces treatment efficacy. However, opinions regarding the risk factors for peripheral neuropathy are currently divided.
