La espasticidad es un desorden motor que hace parte del síndrome de motoneurona superior y se caracteriza por un incremento dependiente de la velocidad del reflejo tónico de estiramiento o de tono muscular; se acompaña de reflejos miotendinosos exagerados e hiperexcitabilidad del reflejo de estiramiento. Es muy frecuente en pacientes con síndrome de motoneurona superior secundario a diversas patologías como ataque cerebrovascular, lesiones medulares, esclerosis múltiple y parálisis cerebral. Un abordaje multidisciplinario e individualizado es fundamental en el tratamiento de los pacientes; e incluye como pilares el manejo no farmacológico, farmacológico, neuroquirúrgico y ortopédico. El presente trabajo pretende realizar una revisión no sistematizada pero actualizada sobre la historia, epidemiología, fisiopatología, abordaje diagnóstico y terapéutico de la espasticidad, tanto en la población adulta como en la pediátrica; así como plantear un algoritmo terapéutico.
Reversible cerebral vasoconstriction syndrome (RCVS) is characterised by severe thunderclap headaches (with or without the presence of acute neurological symptoms) and segmental vasoconstriction of cerebral arteries that resolves spontaneously in a period of three months. Cases have been described in the literature with producing and non-producing masses of metanephrines. Within these reports, associations with cavernous haemangioma, medulloblastoma, colon cancer, paraganglioma, pheochromocytoma, uterine fibroids, among others were found. However, no association with adrenal masses which do not produce metanephrines was found. In this context, we reported the case of a woman with this type of tumour associated with RCVS which provided a treatment challenge, as well as we reviewed the literature on cases of RCVS associated with masses.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
