RESUMO
RESUMEN La COVID -19 afecta predominantemente el sistema respiratorio, pero también se ha descrito compromiso extrapulmonar, incluido la afectación del sistema nervioso. Se describen los casos de dos pacientes con infección por SARS -CoV-2 que desarrollaron el síndrome de Guillain Barré.
SUMMARY COVID-19 predominantly affects the respiratory tract, but extrapulmonary involvement, including the nervous system has been reported. We report two patiets who presented SARS-COV-2 associated of Guillain-Barré syndrome
RESUMO
Algunos síntomas conductuales en personas de la tercera edad, como cambios recientes relacionados a la desinhibición social, podrían representar el estadio inicial de una demencia degenerativa escasamente reconocida por la comunidad médica: la antigua enfermedad de Pick. La degeneración lobar frontotemporal (DLFT) es un desorden neurodegenerativo progresivo que compromete los lóbulos frontal y temporal anterior. Se caracteriza por desórdenes conductuales y del lenguaje. Existen cuatro variantes clínicas: demencia frontotemporal variante conductual (DFTvc), demencia semántica (DS), afasia progresiva no fluente (APNF) y afasia logopénica (AL). La DLFT puede ser confundida con la enfermedad de Alzheimer (EA) o con desórdenes psiquiátricos, especialmente en estadios tempranos. Describimos con detalle las características epidemiológicas, aspectos etiológicos y cuadro clínico, y con especial énfasis, los criterios de diagnóstico y algunas pautas de tratamiento.
Some behavioral symptoms in elderly people, such as recent changes related to social disinhibition, could represent an early stage of a degenerative dementia, barely recognized by medical community: the former Pick's disease. Frontotemporal lobar degeneration (FTLD) is a progressive neurodegenerative disorder that involves the frontal and anterior temporal lobes. It is characterized by prominent behavioral and language disorders. There are four variants of FTLD: behavioral variant of frontotemporal dementia (bvFTD), semantic dementia (SD), progressive non-fluent aphasia (PNFA) and logopenic aphasia (LA). FTLD may be mistaken for Alzheimer's disease (AD) or psychiatric disorders especially in the early stages. We describe in detail epidemiologic characteristics, etiologic aspects, and clinical features; with special emphasis on diagnosis criteria and some treatment guidelines.

Optimum treatment of bronchial asthma requires accurate diagnosis and severity classification. We studied the use of an exercise bronchial challenge in the asthmatic patient as a diagnostic tool. An exercise bronchial challenge test was carried out in 431 asthmatic children and 114 children without a history of asthma in a moderate-altitude environment (2,230 m above sea level/7,314 feet above sea level). Values of peak expiratory flow (baseline and maximum fall) were analyzed through time in each asthma severity group (intermittent, mild persistent, moderate persistent, severe persistent, and nonasthmatic controls). There was a significant difference among responses of asthma severity groups for almost all variables. No difference was found between nonasthmatic and intermittent groups who had similar behavior, except in bronchodilator response. An exercise bronchial challenge helps classify a patient according to asthma severity; it is easy to reproduce and does not require expensive equipment. It allows diagnosing and classifying asthma severity easily and supplementing the clinical evaluation. Based on our results, we propose a fall of PEF >or= 11% as new cutoff point for making a diagnosis of persistent bronchial asthma. A fall of 11-25% indicates mild persistent asthma; from 25-50%, moderate persistent asthma; and a bigger fall, severe persistent asthma.
