Epidemiology of Work-Related Traumatic Brain Injury and COVID-19 Pandemic Lockdown Consequences: Experience in a Reference Center in Chile.

Introduction: Work-related traumatic brain injury is a frequent cause of chronic morbidity, mortality, and high treatment costs. Its causes are highly environmentally determined and were affected by COVID-19 pandemic lockdowns.

We report a 50-year-old woman with a history of celiac disease, who presented with lumbar pain and progressive flaccid tetraparesis 48 hours after the inoculation of the first dose of CoronaVac inactivated SARS-CoV-2 vaccine. CSF was normal and electrodiagnostic studies showed an axonal motor polyneuropathy. No other triggers were identified, and other etiologies were ruled out.
