ABSTRACT
The oil spill at the La Pampilla refinery, managed by REPSOL, will have strong environmentalimpacts on the Peruvian coast, damaging marine life and other biological elements. This study seeks toanalyze the population's perception of the oil spill at the La Pampilla Refinery through a nonexperimental quantitative-descriptive method. The people who participated in the survey, composed of 7items, amounted to 1554 individuals, considering it a representative sample for the study's purpose. The results show that more than 90% of the population identifies REPSOL as responsible for the oil spill. Inaddition, they consider that this environmental disaster will have severe consequences for theenvironment, causing the disappearance of some marine species. Likewise, they conclude that thecontamination will take between two to five years to be eradicated due to the toxic components of thehydrocarbon. (AU)
El derrame ocurrido, en la refinería La Pampilla, administradas por la empresa REPSOL, dejaráfuertes impactos ambientales en la costa peruana, dañando la vida marina y otros componentes bióticos.El estudio analiza la percepción de la población sobre el derrame de petróleo en la Refinería La Pampillaa través de un método de tipo cuantitativo-descriptivo no experimental. La población que participó en laencuesta, compuesta por 7 ítems, ascendió a un total de 1554 personas, considerándose una muestrarepresentativa para el objeto del estudio. Los resultados muestran que la población identifica comoresponsable del derrame petrolero a la empresa REPSOL, con más 90%. Consideran que este desastreambiental acarreará consecuencias muy graves al medio ambiente, ocasionando la desaparición dealgunas especies marinas. Asimismo, concluyen que la contaminación tardará entre dos a cinco años paraser erradicada, debido a los componentes tóxicos del hidrocarburo. (AU)

Miliary metastasis to the central nervous system (CNS) is a rare presentation of metastasis mainly found in primary adenocarcinoma of the lung. Its association with breast cancer is even less frequent. We present the case of a 50-year-old female patient diagnosed in 2010 with stage IIA infiltrating ductal breast cancer RE (-), RP (+), HER 2 (-), HER2 NEU (+). She was treated with modified radical left breast mastectomy, radiation therapy, and chemotherapy. Her condition began presenting oppressive frontal headache without irradiation, predominantly in the evening, intensity 8/10, which decreased when sleeping and was exacerbated with stressful situations, in addition to progressive cognitive deterioration. Simple and contrasted computed tomography (CT) of the skull and thoracoabdominal were requested, showing multiple micronodular lesions with calcium density in the brain parenchyma, left pleural effusion, hypo and hyperdense lesions in the liver parenchyma, as well as osteoblastic lesions in the lumbar spine. Simple and contrasted magnetic resonance imaging (MRI) of the skull showed multiple supra and infratentorial intra-axial lesions. The most frequent associated symptom with miliary metastasis is cognitive impairment. Miliary metastasis, confirmed by imaging studies and histopathology, requires the ruling out of other causes of this calcification pattern, such as neurocysticercosis, due to specific treatment for each pathology.
ABSTRACT
Introducción:El cáncer de la próstata se ha convertido en una patología muy estudiada en los últimos años, debido al incremento de la tasa de mortalidad, que lo ha posicionado en el segundo lugar de causas de decesos en el hombre, después del cáncer de pulmón (1), siendo muchas las técnicas complementarias se encuentran a disposición para tratar de identificarlo, actualmente, el diagnóstico precoz del cáncer prostático se asienta sobre las herramientas clásicas que constituyen un trípode conformado por el tacto rectal (TR), el antígeno prostático específico en suero (PSA) y el examen con ecografía transrectal (ETR), seguido por la biopsia transrectal (BTR), mas no existe un acuerdo generalizado acerca de la indicación precisa para efectuar la biopsia. Objetivos: Determinar la utilidad del valor predictivo de la relación PSA libre/PSA total en el diagnóstico diferencial entre hiperplasia benigna de próstata y carcinoma prostático.Material y métodos: Nivel de Investigación observacional, tipo analítico, prospectivo y transversal. Realizado mediante chi2, curva de ROC y regresión lineal. Resultados: Corte de relación de PSA libre/total en 15%, con una sensibilidad de 83% y una especificidad de 69%, VPP de 51% y un VPN 91% para el diagnóstico de cáncer de próstata. (AU)
Introduction: Prostate cancer has become a very studied pathology in recent years, due to the increase in the mortality rate, which has positioned it in the second place of causes of death in man, after lung cancer (1 ), Many complementary techniques are available to try to identify it, currently the early diagnosis of prostate cancer is based on the classic tools that constitute a tripod formed by rectal examination (TR), prostate-specific antigen in serum ( PSA) and transrectal ultrasound (RTE), followed by transrectal biopsy (BTR), but there is no general agreement about the precise indication for biopsy. Objetive: To determine the usefulness of the predictive value of the free PSA / total PSA ratio in the differential diagnosis between benign prostatic hyperplasia and prostatic carcinoma. Materials and Methods: Level of observational research, analytical, prospective and cross-sectional type. Performed using chi2, ROC curve and linear regression. Results: PSA F/T ratio cut by 15%, with a sensitivity of 83% and a specificity of 69%, PPV of 51% and a 91% NPV for the diagnosis of prostate cancer. (AU)

Desde su establecimiento en la selva central peruana, hacia la década de 1920, los misioneros adventistas han reportado constantemente la permanencia de una serie de manisfestaciones rituales tradicionales entre los conversos asháninkas, las cuales, a pesar de la constante crítica y prédica misionera, siguen teniendo gran vitalidad hasta nuestros días. Entre estas, las que han sido mayormente denunciadas -y enfrentadas por la acción evangelizadora y pastoral- han sido las prácticas de shamanismo y las acusaciones de hechicería. En los últimos años este tema ha despertado un notorio interés dentro de la antropología amazónica; por eso el artículo propone una reflexión sobre las apreciaciones y juicios generados desde la perspectiva misionera acerca de estos fenómenos. A la vez anota cómo la cosmovisión de los indígenas conversos al adventismo, más allá de generar un rompimiento con su religiosidad tradicional y la aceptación de una explicación doctrinal cristiana sobre el origen del mal y la enfermedad, ha generado una interpretación compleja donde tienen vigencia concepciones tradicionales y > para entender el principio y al presencia del mal y el demonio en el mundo.
Since is establishment in the central jungle of Peru, to the 1920's, Adventist missionaries have constantly reported the permanency of a series of traditional rituals among the converted Asháninkas, which despite hard and constant criticism and missionary preaching, retain great vitality to the present day. Among these, the one that has been mainly reported -and then confroted by evangelization and pastoral action- has been the practice of "shamanism" and accusations of witchcraft accusat Understanding that this issue tin the recent years has provoked interest within the Amazonian anthropology, we propose a reflection about the trials generated from the missionary perspective about this phenomena, noting how the worldview of indigenous converts to Adventism, beyond generating a break with their traditional religion and the acceptance of a Christian doctrinal explanation about the origins of the evil and disease, it has generated a complex interpretation of modern and traditional concepts to understand the principle and the presence of evil and the devil in the world.
