Abstract: the common diagnostic methods to know primary hemostasis have been classified as invasive, depending on the operator, difficult to reproduce and at times not very reliable. thus, different systems have been proposed to assess bleeding time, one of them being the pfa-100 device, which we present in this paper. objective: compare specificity between the traditional ivy method with the pfa-100 system to measure bleeding time. material and method: we obtained a sample of 33 patients between the age of 24-80 years receiving anti-platelet treatment who needed to undergo oral surgery. bleeding time was obtained by the ivy method, an inr by an analysis done on the same day and a coagucheck one hour before surgery as well as measurement of bleeding time with the pfa-100 system. results: mean value of bleeding time through the ivy method was 406.36 sec.. mean bleeding time with the pfa-100 system for the collagen/epinephrine cartridge was 226.91 sec. and for the collagen/adp cartridge was 110.27 sec.. all these values were within normality. we observed very high standard deviations with the ivy method and more regular ones for the pfa-100 system, indicating its greater specificity. we also obtained a large correlation between collagen/epinephrine cartridge and acetylsalicylic acid. conclusions: we found greater specificity of the analyzer of pfa-100 platelet function for the measurement of bleeding time in relationship with the traditional ivy method.

Cuadernos Dieciochistas , 2013,
Abstract: Estudio de las modalidades de venta de vino en la provincia de León en el siglo XVIII, fijándonos en la importancia de los productores de vino, gremios de cosecheros , a la hora de controlar y monopolizar el comercio del vino, sobre todo el que se vende al por menor. Donde los cosecheros tienen menor presencia se establece el sistema de los obligados abastecedores, como ocurre en la ciudad de Astorga y las localidades rurales próximas. Además, también se han analizado los conflictos que se producen entre los cosecheros y los poderes municipales, motivados por la venta de vino al por menor, los cuales son más frecuentes en la villa de Ponferrada y sobre todo en la ciudad de León. Wine trade in the province of León in the Eighteenth Century: types and problems. Study of the types of the wine sales in the province of León in the Eighteenth Century, focusing on the importance of wine producers, wine producers’ guilds and how they controlled this trade, especially retail sales. The study also includes other kinds of wine trade organized with forced suppliers such as those in the of Astorga and its surroundings. We have also analyzed the conflicts which happened between the producers and the local authorities, caused by the retail sale which were more frecuent in the cities of Ponferrada and León.

Abstract: fat embolism syndrome (fes) is an uncommon entity characterized by a difficult clinical diagnosis and high morbi-mortality in polytrauma patients. it is the clinical manifestation of the presence of fatty cells in the systemic circulation and it is mainly characterized by the development of respiratory failure, neurologic symptoms and petechial rash. although it has been largely associated with long-bone fractures, it may be caused by other types of pathologies. clinical findings have been classically used for the diagnosis. therefore, we report on four cases where brain magnetic resonance imaging (mri) had a key role in the diagnosis.

Abstract: the pathophysiology of spinal cord injury (sci) is complex and still not fully elucidated. primary and secondary processes determine sci. the initial injury is produced by the transmission of the mechanical energy of the trauma to the spinal cord and neural structures. the secondary injury acts on those structures that were spared by the initial trauma, affecting microvascular perfusion and ionic concentrations, inducing the liberation of free radicals and neurotransmitters and activating lipid peroxidation, thus producing cellular death. recent research in the treatment of sci is focused on the development of timely therapeutic interventions that could attenuate the effects of these secondary pathophysiological mechanisms. among the pharmacological interventions, methyl-prednisolone, gangliosides and antagonists of opiod, glutamate receptor and ionic channels have been used, advocating their theoretical protective effect in the neurological prognosis of patients with sci. nevertheless, none of these interventions has yet significantly modified this prognosis.

Abstract: Uno de los problemas nutricionales más graves e importantes que afecta a la humanidad es la deficiencia de vitamina A. Este trabajo se desarrolló con el objetivo de establecer si hay relación entre el estado de deficiencia de vitamina A y la sepsis urinaria durante el embarazo. Se realizó un estudio ambispectivo con el dise o de casos y controles y bajo la hipótesis de que uno de los factores etiológicos en la sepsis urinaria de la gestante es el déficit de vitamina A. Se estudiaron 40 embarazadas ingresadas en el Hospital Ginecoobstétrico "Mártires de Girón" de Cienfuegos, 20 de ellas con el diagnóstico de sepsis urinaria, y un grupo control. Se estudió la edad, antecedentes patológicos personales, anemia, e ingestión de vitaminas. A todas se les realizó el test de impresión conjuntival para diagnosticar el déficit de vitamina A. Los datos fueron procesados mediante el sistema computadorizado SPSS y se utilizó el estadígrafo Chi cuadrado como prueba de inferencia estadística. Se encontró una elevada asociación entre sepsis urinaria y déficit de vitamina A. La enfermedad estudiada predominó entre las embarazadas más jóvenes, con un elevado número de antecedentes patológicos personales y anemia. Fue contradictorio el hecho de que se encontrara déficit de vitamina A, a pesar de tener una alta ingestión de vitaminas.

UN ACERCAMIENTO AL SENTIMIENTO DEL MIEDO Y SU INCIDENCIA EN LA RECONFIGURACIóN DE LOS ESPACIOS SOCIALES
José Juan Méndez Ramírez,Alberto J. Villar Calvo,Teresa Becerril Sánchez
Urbano , 2009,
Abstract: Para desarrollar el presente trabajo, se partió del siguiente supuesto, el sentimiento del miedo está influenciando la configuración de los espacios sociales, al presentar construcciones encerradas, privatizando espacios que tradicionalmente habían sido considerados como públicos, como es el caso de calles, parques, jardines, sólo por mencionar algunos. En los espacios cerrados se hace presente fuertes dispositivos de seguridad, que van desde el pago de seguridad policíaca con carácter privada, hasta la construcción de altas murallas, la electrificación de bardas, la constante presencia de rejas en puertas y ventanas, como un sinónimo de seguridad y protección de su persona, familia y pertenencias de posibles ladrones o delincuentes. En torno a este supuesto, giran los argumentos que a continuación se presentan.
Does Tamarix dalmatica (Tamari caceae) occur in Spain?
Villar, José Luis,Alonso, María ángeles,Juan, Ana,Crespo, Manuel B.
Anales del Jardín Botánico de Madrid , 2012,
Abstract: The presence of Tamarix dalmatica in the Iberian Peninsula, and its confusion in Spain with the native species T. boveana and T. africana, is discussed. A morphological comparison between these three species, and a critical study of the causes for the confusion between them, is presented. This includes an analysis of the variability in some morphological characters used for the identification of these species, together with clarifications of some discrepancies between the original descriptions and our observations of the type material. As a conclusion, T. dalmatica is excluded from the Iberian and Balearic floras. Se discute la presencia de Tamarix dalmatica en la Península Ibérica e Islas Baleares. Se pone de manifiesto la frecuente confusión de esta especie, en el territorio peninsular, con las nativas T. boveana y T. africana. Se realiza una comparación morfológica entre las tres especies y un estudio crítico de las causas que han provocado dicha confusión. Así mismo, se discute la variabilidad existente en algunos caracteres morfológicos utilizados para la identificación de estas especies, así como algunas discrepancias entre las descripciones originales publicadas y el material tipo. Como conclusión se descarta la presencia de T. dalmatica en la flora ibero-balear.

Abstract: Objective: to analyse the characteristics of colorectal cancer in elderly patients and to assess the outcomes of treatment. Material and methods: the study included 1,924 patients diagnosed with colorectal cancer during a 22 year period (1985-2007). We analysed patient clinical and demographic characteristics as well as their treatment and its outcome. Results: there was an increase in emergency surgery with age, increasing from 13% among patients under 80 years of age to 47% in those over 90 years of age (p = 0.0001). On the other hand, the overall percentage of patients who underwent surgical treatment decreased from 96% in patients younger than 80 years of age, to 85% and 59% in octogenarians and nonagenarians, respectively (p = 0.0001), and there was a similar pattern in the rates of curative surgery among patients who underwent surgery. The overall mortality of patients who underwent surgery was 8% (141 out of 1,769), increasing from 4% in patients younger than 70 years of age to 25% in those over 90 (p = 0.0001). Multivariate analysis showed that the factors associated with mortality were the emergency nature of the surgery (p = 0.001), the ASA grade (p = 0.0001), and the presence of systemic complications (p = 0.0001), the weight of age decreasing significantly with respect to the univariate analysis (p = 0.013). Conclusions: there is an increase in the rate of complicated forms of colorectal cancer with increasing age of patients. In addition, there is a dramatic decrease in the rate of curative tumour resection with increasing age. Intraoperative mortality for colorectal cancer in octogenarians and nonagenarians is more closely related to the nature and intent of the surgery (elective or emergency; palliative or curative), the perioperative risk (ASA grade), and severe systemic complications, than to age. Objetivo: analizar las características del cáncer colorrectal en pacientes ancianos y evaluar los resultados de su tratamiento. Material y métodos: 1.924 pacientes diagnosticados por cáncer colorrectal un periodo de 22 a os (1985-2007). Se analizan parámetros del paciente, clínicos, tratamiento y resultados del mismo. Resultados: hay un incremento de la cirugía de urgencia con la edad, pasando del 13% en pacientes menores de 80 a os al 47% en pacientes mayores de 90 (p = 0,0001). El porcentaje de pacientes sometidos a tratamiento quirúrgico desciende del 96% en los pacientes menores de 80 a os, al 85% en los octogenarios y al 59% en los nonagenarios (p = 0,0001), así como de la tasas de cirugía curativa entre los pacientes sometidos a tratamien
