RESUMO
Fundamento: la escala de trastorno de ansiedad generalizado es útil para evaluar esta afección psiquiátrica en pacientes con epilepsias; sin embargo, no ha sido adaptada ni lingüística ni culturalmente para pacientes con esta enfermedad en el contexto cubano. Objetivo adaptar lingüística y culturalmente la escala de trastorno de ansiedad generalizado para pacientes con epilepsias en el contexto cubano. Métodos trabajo de desarrollo tecnológico I+D+i, realizado en tres etapas: adaptación lingüística y cultural, evaluación por criterios de expertos en el tema y pilotaje en pacientes con epilepsias. Se combinaron técnicas cualitativas y cuantitativas: consulta a lingüistas y expertos, pilotaje, debriefing, alfa de Cronbach (α) y análisis de eliminación de los ítems. Resultados los lingüistas propusieron cambios semánticos mínimos a dos ítems de la escala. El debriefing arrojó que la escala puede administrarse en menos de cinco minutos, con ítems adecuados e inofensivos. El α = 0,83 del pilotaje evidenció buena fiabilidad del test. No fue necesario eliminar ningún ítem de la escala y las correlaciones ítem total se mantuvieron por encima del nivel mínimo (>0,300). Conclusiones: la adaptación semántica y cultural de la escala al español, como se habla en Cuba, preserva equivalencia con la versión original. Se recomienda comprobar la fiabilidad y validez de la escala GAD-7 en una muestra representativa de pacientes con epilepsias en el contexto cubano.
Foundation: the generalized anxiety disorder scale is useful to evaluate this psychiatric condition in patients with epilepsy; however, it has not been adapted linguistically or culturally for patients with this disease in the Cuban context. Objective: linguistically and culturally adapt the generalized anxiety disorder scale for patients with epilepsy in the Cuban context. Methods: I+D+i technological development work, carried out in three stages: linguistic and cultural adaptation, evaluation by criteria of experts on the subject and trial in patients with epilepsy. Qualitative and quantitative techniques were combined: consultation with linguists and experts, trial, debriefing, Cronbach's alpha (α) and item elimination analysis. Results: the linguists proposed minimal semantic changes to two items of the scale. The debriefing showed that the scale can be administered in less than five minutes, with appropriate and harmless items. The α = 0.83 of the trial showed good reliability of the test. It was not necessary to eliminate any items from the scale and the item-total correlations remained above the minimum level (>0.300). Conclusions: the semantic and cultural adaptation of the scale to Spanish, as spoken in Cuba, preserves equivalence with the original version. It is recommended to verify the reliability and validity of the GAD-7 scale in a representative of patients with epilepsy in the Cuban context.
RESUMO
The purpose of this paper is to obtain an electrophysiological evaluation of visual field defects consecutive to the direct lesion of optic radiations in drug-resistant epileptic patients after a standard electrocorticographically adjusted lobectomy, and to correlate it with conventional perimetric results, and with the volume of resected tissue during surgical treatment. Twenty-four patients with temporal lobe epilepsy defined through long term EEG-video, ictal and interictal SPECT, as well as Magnetic Resonance Imaging were studied. Visual evoked potentials (VEPs) with partial and total visual field stimulation were carried out before and after 6, 12 and 24 months surgical treatment. A control group was also studied. No differences between patients and control subjects were observed during the evaluation of the full-field VEPs. However, there were statistical differences between groups in the half-field VEP recordings and in the VEP recordings of contralateral to resected side superior quadrant (CSQ) before lobectomy and 6 months later (Mann-Whitney's U-test, p<0.05). Significant associations were found between VEP abnormalities and perimetric results in CSQ. A close relationship between perimetry, VEPs and volume of the resected tissue in hippocampus, parahippocampus, medial and lower temporal giri was also found. Visual field defects consecutive to standard temporal lobe resection in epileptic patients could be objectively evaluated by partial stimulation VEPs corresponding to the size of resected tissue.
