Primary central nervous system post-transplant lymphoproliferative disorder (PCNS-PTLD) is strongly associated with Epstein-Barr virus (EBV). We analysed intrathecal production of EBV viral capsid antigen (VCA) immunoglobulin (Ig)G and IgA and Epstein-Barr nuclear antigen-1 (EBNA-1) IgG in nine patients with PNCS-PTLD and 20 patients with non-inflammatory neurological diseases (NINDs). Intrathecally produced VCA-IgG was detected in 7/9 (78%), VCA-IgA in 6/9 (67%) and EBNA-1-IgG in 2/9 (22%) patients with PCNS-PTLD, but not in NINDs. This exploratory study suggests that intrathecal EBV antibody production might be frequent in PCNS-PTLD. Detecting intrathecally produced VCA-IgG and VCA-IgA could thus potentially be helpful for diagnosing PCNS-PTLD.

Background And Purpose: Clinical manifestations of Lyme borreliosis (LB), caused by Borrelia burgdorferi sensu lato (Bbsl), include erythema migrans, Lyme neuroborreliosis (LNB), carditis, and arthritis. LB is a notifiable disease in Japan with <30 surveillance-reported LB cases annually, predominately from Hokkaido Prefecture. However, LB, including LNB, may be under-diagnosed in Japan since diagnostic tests are not readily available.

Background: Intrathecal baclofen therapy (ITB) is a well-established treatment modality for severe spasticity, but it is burdened by the need for periodic pump refills. The introduction of a new formulation of baclofen with an extended stability of 180 days (Neteka, Nordic Group BV) could decrease the frequency of refills. We aimed at analyzing the clinical and economic impact of Neteka introduction in our outpatient facility.

Aims: Communication within glial cells acts as a pivotal intermediary factor in modulating neuroimmune pathology. Meanwhile, an increasing awareness has emerged regarding the detrimental role of glial cells and neuroinflammation in morphine tolerance (MT). This study investigated the influence of crosstalk between astrocyte and microglia on the evolution of morphine tolerance.

Despite advances in procedural techniques and equipment, postdural puncture headache (PDPH) remains a serious complication of labour epidural analgesia after accidental dural puncture (ADP). Often considered a temporary inconvenience, PDPH can be debilitating in the short term. It can also be associated with chronic manifestations and serious complications.

Article Synopsis
- Elevated levels of activated complement proteins in cerebrospinal fluid (CSF) are linked to increased severity of multiple sclerosis (MS) and correlate with brain imaging and disease biomarkers.
- A study involving 239 patients analyzed various complement components and liquid biomarkers in CSF, finding specific proteins like C4a, Ba, and C3a strongly associated with accelerated brain atrophy and lesion formation.
- Results indicate that higher levels of these complement proteins are predictive of greater brain volume loss and increased development of lesions, suggesting their potential role as biomarkers for disease progression in MS.
