Epizootic of dolphin morbillivirus on the Catalonian Mediterranean coast in 2007
2011
BETWEEN 1990 and 1992, thousands of striped dolphins (Stenella coeruleoalba) stranded along the Mediterranean coast due to a newly described virus, the dolphin morbillivirus (DMV) (Domingo and others 1990, 1992). DMV is one of the several morbilliviruses that have killed marine mammals worldwide since 1987 (Di Guardo and others 2005). A new DMV epizootic has been recently confirmed from the Mediterranean Spanish and French coasts during 2007 to 2008 (Fernández and others 2008, Raga and others 2008, Keck and others 2010). This short communication describes the pathological findings associated with DMV infection and secondary infections, observed during this epizootic on the Mediterranean coa…
Nitric oxide synthase 2 (NOS2) expression in histologically normal margins of oral squamous cell carcinoma
2014
The activity of Nitric Oxide Synthase 2 (NOS2) was found in oral squamous cell carcinomas (OSCC) but not in normal mucosa. Molecular changes associated to early carcinogenesis have been found in mucosa near carcinomas, which is considered a model to study field cancerization. The aim of the present study is to analyze NOS2 expression at the histologically normal margins of OSCC. Study Design: Eleven biopsy specimens of OSCC containing histologically normal margins (HNM) were analyzed. Ten biopsies of normal oral mucosa were used as controls. The activity of NOS2 was determined by immunohistochemistry. Salivary nitrate and nitrite as well as tobacco and alcohol consumption were also analyzed…
Understanding Discipline in Families of Children with Attention-Deficit/Hyperactivity Disorder: A Structural Equation Model
2009
One hundred and fifty-five mothers of children with attention deficit/hyperactivity disorder (ADHD) completed a semi-structured interview, the Parenting Stress Index Questionnaire (Abidin, 1990), to evaluate parenting stress. The Parenting Scale (Arnold, O’Leary, Wolff & Acker, 1993) was also administered to measure dysfunctional discipline strategies. Structural equation modeling was used to test a model in which the independent variables were the Child’s Characteristics and the Socio-Educational Status of his or her family; intermediate variables were Parenting Stress concerning the Child Domain and concerning the Parent Domain; and the dependent variable was Parental Discipline. The resu…
Seasons and Other Factors Affecting the Quality of Life of Asthmatic Children
2007
Amparo.Escribano@uv.es Objective: To study the effect of seasons on the health-related quality of life (HRQL) of asthmatic children. Methods: Four groups of asthmatic children 7 to 14 years old were recruited by pediatricians during each season of the year. Their HRQL was assessed by means of the Paediatric Asthma Quality of Life Questionnaire (PAQLQ). Other factors surveyed were asthma severity, atopy, medical treatment, immunotherapy, obesity, parental smoking, and anti-allergic measures. Results: The mean (SD) overall PAQLQ score was highest in summer at 6.2 (1.0) and lowest in autumn at 5.5 (1.2). The same trend was found for domains in summer and autumn, respectively: symptoms, 6.2 (1.…
Diagnostic accuracy of nonmydriatic fundus photography for the detection of glaucoma in diabetic patients.
2015
Purpose. To determine the diagnostic accuracy for glaucoma of a set of criteria with nonmydriatic monoscopic fundus photography (NMFP) in diabetics. Methods. Diabetics recruited from a screening program for diabetic retinopathy and diabetic glaucoma patients recruited from our glaucoma unit were included. Any patient with evidence of diabetic retinopathy was excluded. Diabetic patients had to have no visual field defects to be included as controls. Glaucoma patients had to have a glaucomatous field defect in at least one eye to be included. One NMFP was taken per eye for all subjects. These photographs were evaluated by two masked glaucoma specialists for the presence of the following: bila…
La matriz extracelular: morfología, función y biotensegridad (parte I)
2009
La matriz extracelular (MEC) representa una red tridimensional que engloba todos los órganos, tejidos y células del organismo. Constituye un filtro biofísico de protección, nutrición e inervación celular y el terreno para la respuesta inmune, angiogénesis, fibrosis y regeneración tisular. Y representa el medio de transmisión de fuerzas mecánicas a la membrana basal, que a través de las integrinas soporta el sistema de tensegridad y activa los mecanismos epigenéticos celulares. La alteración de la MEC supone la pérdida de su función de filtro eficaz, nutrición, eliminación, denervación celular, pérdida de la capacidad de regeneración y cicatrización y alteración de la transmisión mecánica o …
Miocarditis de células gigantes: caso de evolución rápida y fatal.
2006
La miocarditis de células gigantes (MCG) es una patología extremadamente infrecuente de origen desconocido y evolución fatal, que presenta histológicamente infiltrado inflamatorio miocárdico con presencia de células multinucleadas gigantes, sin apreciarse formación de granulomas. En el estudio inmunohistoquímico, las CGM expresan el marcador propio de la estirpe macrofágica CD68, siendo negativos para los marcadores musculares desmina y actina. La MCG se ha asociado a diversas entidades autoinmunes, infecciones virales, neoplasias y fármacos. Presentamos los resultados obtenidos de la necropsia realizada a un paciente de 55 años, que mostró de forma simultánea MCG, tiroiditis linfocitaria y…

MetAphAs Test. Metalanguage in Aphasia Assessment.
2018
Test MetAphAs: La evaluación del metalenguaje en la afasia (Rosell-Clari & Hernández-Sacristán, 2018) es una versión adaptada y abreviada de Rosell Clari & Hernández Sacristán, 2014). Esta prueba fue desarrollada inicialmente para evaluar las habilidades metalingüísticas naturales en personas con afasia (Hernández-Sacristán, Rosell-Clari, Serra-Alegre y Quiles-Climent, 2012). Las habilidades metalingüísticas naturales se refieren al uso del lenguaje que revela reflexividad (Hockett, 1960); es decir, la distancia perceptiva del hablante con respecto a su propio comportamiento verbal (Werner & Kaplan, 1978). Esta autoconciencia del lenguaje nos permite monitorear nuestros propios comportamien…
Odontogenic tumors in children and adolescents: A 15-year retrospective study in Argentina
2007
There are few studies on bucco-maxillary lesions in children and adolescents, and reports on odontogenic tumors (OT) are scanty. Comparison among the available data is difficult due to differences in the criteria used in each study. The aim of the present work was to perform a retrospective study of OT in patients aged up to 20 years diagnosed at a center specialized in histopathologic diagnosis of oral diseases. All cases diagnosed with OT between 1990 and 2004 were retrieved from the Service archives. The 153 retrieved cases accounted for 7% of total biopsies performed during that period, and to 78.4% of tumors of the jaws. Mean age of the whole population was 12.7 years and the male to f…
