Application and interpretation of core elements of the 2015 NMOSD diagnostic criteria in routine clinical practice.
Front Immunol
December 2024
Department of Neurology, University of Virginia, Charlottesville, VA, United States.
Background: We evaluated comprehension and application of the 2015 neuromyelitis optica spectrum disorder (NMOSD) criteria core elements by neurologists in Latin America (LATAM) who routinely diagnose and care for NMOSD patients by (i) identifying typical/suggestive NMOSD syndromes, (ii) detecting typical MRI NMOSD lesions and meeting MRI dissemination in space (DIS) criteria, and (iii) evaluating historical symptoms suggestive of NMOSD.
Methods: We conducted an anonymous, voluntary, self-administered web- and case-based survey cross-sectional study from October 2023 to January 2024 of neurologists identified through the LACTRIMS database. Questions were presented first through iterative clinical cases or imaging, followed by questions directly evaluating comprehension of definitions.
MOG-IgG is rare in AQP4-IgG seronegative NMO phenotype in Brazil.

CIEM MS Research Center, Federal University of Minas Gerais Medical School, Belo Horizonte, MG, Brazil.
Background: Neuromyelitis optica spectrum disorder (NMOSD) is a rare autoimmune disease most frequently characterized by a neuromyelitis optica (NMO) phenotype, comprising both simultaneous or sequential optic neuritis (ON) and longitudinally extensive transverse myelitis (LETM). Symptoms of brainstem, diencephalic and cerebral involvement may also occur. While most NMOSD patients test positive for serum aquaporin-4 (AQP4) antibodies, some seronegative patients test positive for oligodendrocyte glycoprotein-IgG (MOG-IgG).

Across studied vertebrates, the medial amygdala (MeA) is a central hub for relaying sensory information with social and/or survival relevance to downstream nuclei such as the bed nucleus of stria terminalis (BNST) and the hypothalamus. MeA-driven behaviors, such as mating, aggression, parenting, and predator avoidance are processed by different molecularly defined inhibitory and excitatory neuronal output populations. Work over the past two decades has deciphered how diverse MeA neurons arise from embryonic development, revealing contributions from multiple telencephalic and diencephalic progenitor domains.

The exposure to aversive experiences during early-life affects brain maturation and induces changes in behavior. Additionally, when these experiences coincide with subtle neurodevelopmental alterations, they may contribute to the emergence of psychiatric disorders, such as schizophrenia. Studies in patients and animal models have identified changes in parvalbumin (PV) expressing inhibitory neurons, highlighting their significance in the etiology of this disorder.

Clin Neuropathol
December 2024
Thyroid transcription factor-1 (TTF-1) is a nuclear protein primarily recognized for its role in the development and differentiation of thyroid, lung, and certain diencephalic tissues. Although well-established as an immunohistochemical marker in thyroid and lung cancers, recent studies have explored its expression and diagnostic value in primary central nervous system (CNS) tumors. This systematic review aims to consolidate current knowledge on TTF-1 immunohistochemistry in primary CNS tumors, assessing its prevalence, diagnostic utility, and clinical implications.
