Differentiating Familial Neuropathies from Guillain-Barré Syndrome

A Comprehensive Review on Navigating the Neurological Landscape of COVID-19: Insights Into Etiopathogenesis and Clinical Management

The coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has emerged as a global health crisis with significant neurological implications. While initially characterized by respiratory symptoms, COVID-19 has been increasingly recognized for its diverse neurological manifestations, including encephalopathy, stroke, peripheral neuropathies, and neuropsychiatric disorders. Understanding the neurological landscape of COVID-19 is essential for elucidating its pathophysiology, optimizing clinical management, and improving patient outcomes. This comprehensive review provides insights into the etiopathogenesis, clinical manifestations, diagnostic approaches, management strategies, and prognostic implications of neurological involvement in COVID-19. Mechanistic insights highlight the multifactorial nature of neurological complications involving direct viral invasion, immune-mediated mechanisms, and thrombotic events. Diagnostic challenges underscore the importance of a multidisciplinary approach to patient care, while management strategies emphasize early recognition and appropriate intervention. Long-term neurological sequelae and prognostic factors are also examined, emphasizing the need for comprehensive follow-up and rehabilitation services. Finally, recommendations for future research prioritize efforts to elucidate underlying mechanisms, identify biomarkers, and evaluate rehabilitative interventions. By addressing these challenges, we can better understand and mitigate the neurological consequences of the ongoing COVID-19 pandemic.

The genetic counseling in a patient affected by congenital polyneuropathy after a “diagnostic odyssey” recently solved with WES approach

Counseling after WES/WGS presents challenges for healthcare providers as the availability of consumer-driven is rapidly increasing. The present report uncovers an extremely rare homozygous nonsense mutation c. 1639C>T (p.Gln547Ter) in PRX gene of a patient with heterogeneous manifestation of Charcot-Marie-Tooth. Such studies can help to conduct genetic counseling and subsequently more accurate support to individual cases with neuro-genetic conditions and solved through whole genome/exome-wide screening.

Porfiria intermitente aguda como desencadenante de síndrome de Guillain-Barre

Introducción. La porfiria es un conjunto de enfermedades metabólicas que tienen como base fisiopatológica la acumulación de precursores tóxicos. Su similitud clínica con enfermedades como el síndrome de Guillain-Barre puede retrasar el diagnostico, aumentando la posibilidad de complicaciones.Presentación del caso. Paciente femenino quien presentó síntomas inespecíficos de porfiria y síndrome de Guillain-Barre. La mujer fue evaluada de manera integral y recibió tratamiento para ambas patologías, respondiendo de manera inusual.Conclusión. La respuesta farmacológica atípica encontrada y la relación causa-efecto entre ambas entidades se justifica a la luz de sus procesos fisiopatológicos y la respuesta inmune desencadenada por los mismos.
