Isolement du sérotype 0:5,27 de Yersinia enterocolitica à partir d'une langue porcine au Maroc

Une souche de Yersinia enterocolitica sérotype 0:5,27, isolée à partir d'une langue de porc apparemment saine, a été étudiée pour ses caractéristiques biochimiques, antibiotiques et de pathogénicité. La souche de biotype 3 répond à toutes les épreuves de virulence utilisées. Du point de vue antibiogramme, elle s'est averée sensible à de nombreux antibiotiques

Factors associated with violence against children in low- and middle-income countries:A systematic review and meta-regression of nationally representative data

Background: This systematic review and meta-regression sought to identify the relative importance of factors associated with physical, emotional, and sexual violence against children in low- and middle-income countries. Understanding of factors associated with violence is important for targeted programming and prevention on the population level. Methods: We searched 17 electronic databases from 1989 to 2018 and reports from child violence surveys. Nationally representative studies that described evidence on potential factors associated with violence against children under 18 years old were included. The search was restricted to the English language. Factors were synthesized quantitatively using robust variance estimation, with 95% confidence intervals, for each violence type. Results: We identified 8,346 unduplicated studies, and 103 publications met our eligibility criteria. The data distribution was uneven across region, country income status, factors, and violence types. Of the 94 eligible studies quantitatively synthesized, no specific factors were significant for physical violence. Lower household socioeconomic status, being a girl, and primary education of mothers and adults in the household were associated with emotional violence, and being a girl was associated with sexual violence. Conclusion: A broad spectrum of factors merit consideration for physical violence policy and prevention among the general population of children in low- and middle-income countries. Conversely, a tailored approach may be warranted for preventing emotional and sexual violence. Information is unequally distributed across countries, factors, and violence types. Greater emphasis should be placed on collecting representative data on the general population and vulnerable subgroups to achieve national reductions in violence against children. </jats:sec

Gastric Syphilis Mimicking Adenocarcinoma: A Case Report

Syphilis is an unexpected diagnosis in the stomach, and the reduced incidence of syphilis has made its clinical presentation less widely appreciated. We report a 43-yr-old man suffering from epigastric tenderness with an initial diagnosis of gastric carcinoma; gastric syphilis was confirmed by demonstrating spirochetes in a gastric biopsy specimen by silver impregnation. Excessive lymphoplasmacytic infiltration with diffuse thickening of gastric rugae should raise suspicion of gastric syphilis, which should be considered in the differential diagnosis of diffuse erosive gastritis and infiltrative lesions of the stomach

Left atrial myxofibrosarcoma: Diagnostic approach through imaging techniques

AbstractPrimary cardiac sarcomas are rare. A 63-year-old woman presented with progressive symptoms of fatigue, palpitations, and dyspnea. Transthoracic echocardiography detected a mass in the left atrium, fixed and probably attached to the interatrial septum suggestive of myxoma. Transesophageal echocardiography confirmed the existence of a large lobulated mass in the left atrium measuring 45mm×25mm in diameter. Subsequent cardiac magnetic resonance imaging showed a mass of heterogeneous appearance, with broad base of implantation on the posterior wall of the left atrium. The extension study with multidetector computed tomography showed superficial infiltration of the atrial wall, without involvement of the mitral valve or pulmonary veins and no extension to other extracardiac structures. The patient underwent surgery resecting a bilobed mass, smooth and yellowish, strongly attached to the posterior wall of left atrium. The pathologic study was consistent with the diagnosis of myxofibrosarcoma.<Learning objective: Primary cardiac tumors are among the most challenging disease entities to diagnose because of their rarity and highly variable and usually nonspecific clinical presentation. Although the definitive diagnosis of a cardiac tumor, whether benign or malignant and the tumor type is provided by histological examination, imaging techniques are essential for confirming the existence of a cardiac mass and characterizing the tumor before obtaining a sample for pathologic examination.

Aprender a usar la biblioteca

Actualmente, la competencia lingüística de los estudiantes es cada vez más baja.Por ello, el objetivo principal de esta experiencia didáctica es potenciar el uso de la biblioteca por parte del alumnado del centro y acercarles a la lectura. El objetivo final es lograr tener una biblioteca en la que se complemente la tarea que se realiza en el aula, que esté bien surtida de libros y organizada y en la que resulte fácil buscar la información necesaria. La actividad está dirigida a los alumnos de primero y segundo de ESO a los que se les enseña a usar la biblioteca. Para ello se les pide que realicen un trabajo de investigación buscando información en los fondos de la biblioteca. El proyecto se realiza a lo largo del tercer trimestre y se le dedica una hora semanal de trabajo guiado en el aula. Se realiza una visita al lugar objeto de estudio, donde los alumnos realizan fotografías del lugar para ilustrar sus propios trabajos. Además, los alumnos tienen que realizar un trabajo individual de documentación consultando todo tipo de bibliografía. Finalmente se ponen los trabajos en común y se realiza una autoevaluación. Se adjuntan fichas-guía utilizadas por los alumnos.Madrid (Comunidad Autónoma). Consejería de Educación. Dirección General de Ordenación AcadémicaMadridMadrid (Comunidad Autónoma).
