Revolución digital en salud: ¿están los pacientes con accidente cerebrovascular preparados? / Digital revolution in healthcare: are stroke patients ready?

Background: The digital revolution is creating opportunities and challenges in the field of medicine and the Digital Hospital could be a benefit for patients, if they are able to use the Internet. Aim: Identify the barriers that limit Internet use among stroke patients treated in a public hospital in Santiago. Material and Methods: Sociodemographic, clinical and functional variables that could influence the use of the Internet were collected in 107 patients with stroke. Results: Seventy five percent of patients had access to the Internet, but only 29% knew how to use it before their hospitalization. Seventy five percent were older adults, 74% had a low level of education, 78% had an income below the minimum Chilean salary and 56% were discharged with a severe disability (modified Rankin Scale 4 or 5). There was a significant relationship between Internet use and the level of education, income and age. Conclusions: Income levels, age, schooling and stroke related disability limit Internet use in this population.

Encefalitis autoinmune reversible y anticuerpos anti-receptores de N-metil-D-aspartato: Report of one case / Limbic encephalitis with positive anti-N-methyl-D-aspartate antibodies

Background: Limbic encephalitis is a subacute syndrome characterized by memory impairment, confusion, seizures, hypothalamic dysfunction and psychiatric symptoms. It has been associated to tumors located outside of the central nervous system. In 2007, anti-N-methyl-D-aspartate receptors (NMDAr) antibodies were found in serum and CSF of patients with this particular type of encephalitis. We report a 25-year-old female who, following upper respiratory tract symptoms, developed serious behavioral and consciousness impairment that progressed to coma. Cerebrospinal fluid (CSF) analysis showed a lymphocyte pleocytosis, the electroencephalogram was altered with a slow encephalopathic rhythm and a brain magnetic resonance imaging was normal. Infectious etiologies were ruled out. CSF and serum anti NMDA receptors antibodies were positive.

Glioma multifocal multicéntrico / Multifocal multicentric glioma

El glioblastoma multiforme es el más habitual y agresivo de los tumores gliales del sistema nervioso central, sin embargo, infrecuentemente se expresa con lesiones múltiples que pueden definirse como multifocales o multicéntricas, en relación a su origen y capacidad de propagación. Esta presentación intenta analizar las peculiaridades clínicas y los hallazgos imagenológicos de un paciente portador de un glioblastoma multiforme con lesiones supra e infratententoriales, de aparición sincrónica y metacrónica. Llamó la atención en él, que importantes masas tumorales de la protuberancia y mesencéfalo no comprometieran los pares craneales. También fue significativa la visualización en el cuerpo calloso de la propagación selectiva del glioma a través de fibras de conexión. Se concluye que las manifestaciones tanto clínicas como imagenológicas de este paciente son excepcionales por la ausencia de signología esperable por la localización de las múltiples lesiones infra y supratentoriales del tumor, y la visualización del modo de propagación.

Glioblastoma multiforme is the most common and most aggressive glial tumor of central nervous system, however it is infrequently expressed with multiple lesions that can be defined as multifocal or multicentric, relative to their origin, and spread capacity. This presentation makes an effort to analyze clinical peculiarities and radiographic findings of a patient suffering from a glioblastoma multiforme with supra and infratentorial lesions, that appeared synchronic and metachronically. In this case, drew our attention that important tumor masses at pons and midbrain did not compromise cranial nerves. Also, it was significant the visualization at corpus callosum of glioma's selective spreading through connection fibers. It is concluded that both clinical and radiographic manifestations from this patient are exceptional, because of the absence of expected signology from the multiple infra and supratentorial lesions, and the visualization of the way of spreading.

Oftalmoplejia aguda sin ataxia de carácter recurrente / Recurrent acute ophthalmoplegia without ataxia

Pueden mostrar aumento de anticuerpos anti-GQ1b los síndromes de Miller Fisher, Guillain-Barré con Oftalmoplegia, Rombencefalitis de Bickerstaff y Oftalmoplejia Aguda sin Ataxia, llamadas síndromes anti-GQ1b. Presentamos hombre de 72 años que ingresa por diplopía, oftalmoplejia de instalación aguda y dolor retro-ocular. Tuvo un episodio semejante hace cinco años, recuperado. Al ingreso mostraba oftalmoplejia completa bilateral sin ptosis, miosis y leve enoftalmo del ojo derecho. Potencia muscular conservada, arreflexia osteotendinea, sin compromiso cerebeloso ni sensitivo. LCR y electromiografía normales. RM de cerebro mostraba captación e hiperintensidad (T2) de los pares tercero y sexto. RM de medula espinal no mostró cambio de las raíces espinales. Aumento de GQ1b de 46.2/ 25 en el suero. Mejoró sin tratamiento. Treinta días después, quedaba solo paresia de los sextos pares. El anti-GQ1b es un marcador que identifica las neuropatías con compromiso oculomotor. Las oftalmoplejias agudas sin ataxia tienen reflejos conservados, el 30 por ciento tiene arreflexia. Sólo existen reportes de Síndrome de Guillain-Barré y Miller-Fisher recurrentes con anti-GQ1b. Sería el primer caso descrito de Oftalmoplejia aguda sin ataxia anti-GQ1b, recurrente.

They may exhibit increased anti-GQ1b antibodies in Miller Fisher syndrome, Guillain-Barre syndrome with ophthalmoplegia, Bickerstaff Rhombencephalitis, and Acute Ophthalmoplegia without ataxia , the so called anti-GQ1b syndromes. We report a 72 years old man who was admitted because of diplopia, acute onset ophthalmoplegia and retro-ocular pain. He had a similar episode five years ago, fully recovered. At admission he showed complete bilateral ophthalmoplegia without ptosis, miosis and slight enophthalmos of the right eye. Preserved muscle strength, deep tendon areflexia, without sensory or cerebellar commitment. CSF and electromyography were normal. Brain MRI showed uptake and T2 hyperintensity of the third and sixth cranial nerves. Spinal cord MRI showed no change in the spinal roots. Serum anti-GQ1b increase of 46.2 / 25. He improved without treatment. Thirty days later, paresis was only the sixth pair. The anti-GQ1b is a marker that identifies neuropathies with oculomotor commitment. The acute ophthalmoplegia without ataxia have normal reflex, 30 percent had areflexia. There are only Guillain-Barré and Miller-Fisher syndromes recurrent case reports with anti-GQ1b. It would be the first case of recurrent anti-GQ1b-positive acute ophthalmoplegia without ataxia.
