ABSTRACT
Acute disseminated encephalomyelitis (ADEM) is an inflammatory emyelinating disease of the central nervous system that is usually considered a monophasic disease Post-vaccination ADEM has been associated with several vaccines, however, there is scarce information related to SARS-CoV-2 vaccines. We present the case of a 26- year-old female who suffered from ADEM four weeks after Gam-COVID-Vac administration.
ABSTRACT
Marchiafava-Bignami disease (MBD) is a rare disorder of unknown etiology, strongly associated with alcoholism and malnutrition. MBD causes primary involvement of the corpus callosum, leading to confusion, dysarthria, seizures, and frequent death. We report the case of a 54-year-old male without a history of alcoholism or known malabsorption disease, who presented with altered consciousness and neurologic impairment. Complex B deficiency was addressed. Magnetic resonance imaging (MRI) showed typical corpus callosum lesions. The clinical features and radiologic images suggested spinal cord involvement. Brain histopathologic findings were consistent with MBD. Despite vitamin replacement therapy, he had a poor outcome.
ABSTRACT
El granuloma piógeno de la cavidad oral ocurre entre el 2 y el 5% de las gestantes. En su patogenia se sospecha la acción de irritantes locales sobre un metabolismo tisular alterado por la acción de las hormonas sexuales. Presentamos una paciente de 26 años sin antecedentes patológicos que cursa el octavo mes de gestación. Consulta por presentar una lesión exofítica en gíngiva inferior de 6 meses de evolución. El estudio histopatológico informa compatible con tejido de granulación. Luego de 2 meses posparto se observa una gradual involución del granuloma. Se investigaron receptores de estrógeno y progesterona, los cuales resultaron negativos.
