    Abstract La esclerosis múltiple (EM) es una enfermedad autoinmune del sistema nervioso central (SNC) que se puede presentar de formas muy variadas y progresa generando discapacidad. Menos del 5% de los casos son pediátricos, y aún menos frecuentes son los casos de EM de formas agresivas o de alta actividad. Presentamos el caso de un adolescente de 13 años que en seis meses tuvo tres brotes, cada vez más agresivos, con una alta carga de lesión evidenciada en la resonancia magnética y rápida progresión de su discapacidad. Discutimos la aproximación diagnóstica de la EM en la edad pediátrica, su forma de presentación y la valoración de formas de EM con alta actividad.

    Title translation Productivity, visibility and citation analysis of the Revista Peruana de Medicina Experimental y Salud Pública, 2002-2009.
    Abstract Biomedical journals are the most used and important venue to disseminate and interchange scientific information, and evaluation is an important component. A bibliometric study was conducted on the productivity, visibility and citation analysis of the Revista Peruana de Medicina Experimental y Salud Pública (RPMESP), from 2002 to 2009. During this period, the RPMESP published about 62 documents per year, 55.3% were research articles. The visibility of RPMESP, determined among three databases (SISBIB-UNMSM, SciELO-Peru, and REDALYC), was irregular, increasing on July 2006, with the highest access on October 2009 (117,618 hits). 43.0% of publications were cited. The calculated impact factor in ISI journals was 0.04 in 2009. In conclusion, the citation of RPMESP shows a slowly growing during the period 2002-2009. It is hoped that the RPMESP increase its visibility and impact after its inclusion in MEDLINE.

    Abstract Background: There are several ecological studies, but few studies of the prevalence of SARS-COV-2 at high altitude. We aimed to estimate the population-based seroprevalence of SARS-COV-2 in three settings of Cusco at the end of the first wave among adults.
    Methods: A population-based survey was conducted in September 2020, in three settings in the region of Cusco: (1) Cusco city at 3,300 meters above the sea level (m.a.s.l.), (2) the periphery of Cusco (Santiago, San Jerónimo, San Sebastián, and Wanchaq) at 3,300 m.a.s.l., and (3) Quillabamba city, located at 1,050 m.a.s.l. People aged ≥ 18 years within a family unit were included. The diagnosis of SARS-CoV-2 infection was based on identifying anti- SARS-CoV-2 total antibodies (IgM and IgG) in serum using the Elecsys Anti-SARS-CoV-2 chemiluminescence test.
    Results: We enrolled 1924 participants from 712 families. Of the total, 637 participants were anti-SARS-CoV-2 seropositive. Seroprevalence was 38.8% (95% CI [33.4%-44.9%]) in Cusco city, 34.9% (95% CI [30.4%-40.1%]) in the periphery of Cusco, and 20.3% (95% CI [16.2%-25.6%]) in Quillabamba. In 141 families (19.8%; 95% CI [17.0%-22.8%]) the whole members were positive to the test. Living with more than three persons in the same house, a positive COVID-19 case at home, and a member who died in the last five months were factors associated with SARS-COV-2 seropositivity. Dysgeusia/dysosmia was the symptom most associated with seropositivity (aPR = 2.74, 95% CI [2.41-3.12]); whereas always wearing a face shield (aPR = 0. 73; 95% CI [0.60-0.89]) or a facial mask (aPR = 0.76, 95% CI [0.63-0. 92) reduced that probability.
    Conclusions: A great proportion of Cusco's city inhabitants presented anti-SARS-CoV-2 antibodies at the end of the first wave, with significant differences between settings. Wearing masks and face shields were associated with lower rate of seropositivity; however, efforts must be made to sustain them over time since there is still a high proportion of susceptible people.

    Abstract Las revistas biomédicas son el medio más usado e importante para la difusión e intercambio de información científica y la evaluación es un componente importante dentro de su gestión. Se realizó un estudio bibliométrico de la producción, visibilidad y citación de la Revista Peruana de Medicina Experimental y Salud Pública (RPMESP), de 2002 a 2009. En tal periodo, la RPMESP publicó en promedio 62 documentos por año, siendo 55,3% artículos de investigación. La visibilidad de la RPMESP, determinada al cuantificar las solicitudes a través de tres indizadoras (SISBIB-UNMSM, SciELO-Perú, y REDALYC), fue irregular, incrementándose a partir de julio 2006, con una máxima de 117618 solicitudes en octubre 2009. Se citó el 43,0% de las publicaciones. El factor de impacto calculado en revistas ISI fue de 0,04 para el 2009. En conclusión, la citación de la RPMESP muestra un crecimiento lento durante el periodo 2002-2009. Se espera que la RPMESP incremente su visibilidad e impacto luego de su inclusión en MEDLINE.
