Value of the critical flicker frequency in patients with minimal hepatic encephalopathy
Minimal hepatic encephalopathy (MHE) is mainly diagnosed using psychometric tests such as the psychometric hepatic encephalopathy score (PHES). Despite the clinical and social relevance of MHE, psychometric testing is not widespread in routine clinical care. We assessed the usefulness of the critical flicker frequency (CFF), for the diagnosis of MHE and for the prediction of the development of overt episodes of HE. The normal range of PHES in the Spanish population was evaluated in a control group. Subsequently, 114 patients with cirrhosis and 103 healthy controls underwent both PHES and CFF tests. A diagnosis of MHE was made when the PHES was lower than −4 points. Patients were followed-up…
Tablas de normalidad de la población española para los tests psicométricos utilizados en el diagnóstico de la encefalopatía hepática mínima
Fundamento y objetivo La encefalopatia hepatica minima (EHM) ha ganado importancia en la practica clinica porque su presencia se asocia a un claro deterioro de la calidad de vida del paciente cirrotico y a la incapacidad de conducir automoviles, y es la antesala para el desarrollo de episodios de encefalopatia hepatica clinica. La Psychometric Hepatic Encephalopathy Score (PHES), compuesta por el test de conexion numerica A (TCN-A), el test de conexion numerica B (TCN-B), el test de simbolos y numeros (TSN), el test de marcacion seriada (TMS) y el test de la linea quebrada (TLQ), es muy util en el diagnostico de la EHM. El objetivo de este trabajo ha sido disenar las tablas de normalidad de…
