Sirs: The blink reflex (BR) test evaluates the integrity of the trigeminalfacial arc. Unilateral electrical stimulation of the supraorbital nerve evokes two separate contractile responses in the orbicularis oculi muscle. The early (R1) component is evoked only on the side of stimulation as a pontine reflex, whereas the late (R2) component is recorded bilaterally and is presumed to be relayed through polysinaptic pathways of the pons and the lateral medulla. We report a case of trigeminal hypoesthesia with abnormalities in the BR demonstrative of a pontine lesion which was correlated with the lesion identified by magnetic resonance imaging (MRI).A 38-year-old woman was diagnosed as suffering from myasthenia gravis. She had a positive tensilon test, decremental response to repetitive stimulation of the cubital nerve, positive single-fiber electromyography in the extensor digitorum communis muscle, and positive anti-acetylcholine receptor antibodies. Her clinical evolution showed tactile hypoesthesia with dysesthesias in the three branches of the right trigeminal nerve to the vertex. Examination showed a tactile sensory deficit in the territory of this nerve with absent corneal reflex. There was no motor involvement. The remainder of the neurological examination was normal. The following neurophysiological tests were carried out: BR, somatosensory evoked potentials (SEPs) on both trigeminal nerves and brainstem auditory evoked potentials (BAEPs). BR recordings (Fig. 1) showed an absent R1 component to right supraorbital nerve stimulation, with normal R2 components latencies bilaterally and a normal latency of R1, R2I, and R2, C components to left supraorbital nerves stimulation. The SEP of the left trigeminal nerve was normal (P1:20 ms). No response to stimulation of the right side was be recorded. BAEPs showed a 0.4-ms relative prolongation of the III-V interpeak latency to right ear stimulation. Based on the results of the electrophysiological tests a subsequent cranial MRI was performed which showed an area of high signal intensity approximately 4.2 mm in diameter in the caudal part of the right pontine tegmentum (Fig. 2). This lesion corresponded to the location of the principal trigeminal sensory nucleus and spared the intra-axial mixed sensory and motor trigeminal nerve fascicles. This is a case of Kimura's third pattern [7]. The restriction of the BR abnormality to the R1 component in-LETTER TO THE EDITORS Fig. 1 A, B Blink reflex.

<p> Introducción: Según el informe de 2008 del Sistema Nacional de Salud, existe un 4,7% de los usuarios que opina que el sistema sanitario debería rehacerse por completo y casi un 27%, que es necesario introducir cambios importantes para su mejora.<br />Hipótesis: El desarrollo de un programa específico de control de peso para pacientes obesos en Atención Primaria mejora la calidad de la actuación percibida por el paciente de Atención Primaria.<br />Objetivos: Valorar la influencia de un proyecto de mejora de calidad de Atención Primaria en los resultados globales de una encuesta de satisfacción de los usuarios de dicha Zona Básica de Salud.<br />Material y Métodos: Estudio prospectivo de intervención cuasiexperimental centrado en el tratamiento de la obesidad en Atención Primaria realizado desde Enero de 2012 a Diciembre 2013, en cuya evaluación final se realizó una encuesta autoadministrada de Satisfacción de los usuarios y se comparó con los resultados obtenidos con el mismo cuestionario por el Servicio Aragonés de Salud en dicha Zona Básica de Salud. Para el análisis estadístico de estos datos se empleó el programa informático SPSS.15.<br />Resultados principales: Se observa un aumento destacable en los apartados “Interés del personal de enfermería”, “Satisfacción de los cuidados sanitarios” (medicina y enfermería) y “Solución dada a problemas”. No hubo aspectos negativos y el 100% de los encuestados expresó una satisfacción general y un 88% destacó el aspecto de la paciencia del profesional hacia los pacientes.</p><p>Conclusión: El proyecto de mejora de calidad realizado con pacientes crónicos de la consulta de enfermería de Atención Primaria, ha sido valorado muy satisfactoriamente, llegando a mejorar la puntuación de los resultados globales del Sistema Aragonés de Salud en esta Zona Básica de Salud.</p><p> </p>
