Uso de la ecografía con contraste en el diagnóstico y manejo de la colecistitis aguda gangrenosa
2017
INTRODUCCIÓN La colecistitis aguda gangrenosa es considerada un verdadero reto para el cirujano general, no ya solo por la dificultad diagnóstica de la misma, sino por la necesidad de un tratamiento rápido y agresivo, por lo que en muchas ocasiones está asociado a una mayor morbilidad y mortalidad perioperatoria. La colecistitis gangrenosa es una evolución de la colecistitis aguda y suele observarse cuando se produce un retraso en el diagnóstico desde el inicio de los síntomas. El aumento de la tensión de la pared vesicular secundario a la obstrucción persistente del conducto cístico acarrea una lesión en el epitelio debido a la insuficiencia vascular subyacente. Estos cambios son los causa…
The new version of the pictorial scale of Perceived Movement Skill Competence in Spanish children: Evidence of validity and reliability. [La nueva ve…
2019
The purpose of this study was to i) examine reliability and construct validity of the pictorial scale of Perceived Movement Skill Competence (PMSC) aligned to the third version of the Test of Gross Motor Development (TGMD-3) in a sample of Spanish children; and to ii) analyse the validity of the PMSC and children’s perceived motor competence (MC) according to gender. A convenience sample of 361 children (55.7% boys) between 4 and 11 years-old participated. The pictorial scale of PMSC (19 items) was administered (a random subsample repeated the PMSC twice). Test-retest reliability using Intraclass Correlation Coefficients and construct validity using a Bayesian Structural Equation Modeling a…
Historia del concepto de especie en biología
2021
Resumen basado en el de la publicación Resumen en inglés Se aborda el problema más antiguo y más frustrante en biología, el problema de las especies. Cubre la evolución del concepto de especie en los últimos 2300 años, y sus muchos altibajos de la biología ya desde Aristóteles. Se discute el papel que el concepto moderno de especies biológicas juega en la biología evolutiva, y enfatiza su importancia en la enseñanza de la biología. ESP
Epigenetic involvement in Hutchinson-Gilford progeria syndrome: a mini-review.
2013
Hutchinson-Gilford progeria syndrome (HGPS) is a rare human genetic disease that leads to a severe premature ageing phenotype, caused by mutations in the <i>LMNA</i> gene. The <i>LMNA</i> gene codes for lamin-A and lamin-C proteins, which are structural components of the nuclear lamina. HGPS is usually caused by a de novo <i>C1824T</i> mutation that leads to the accumulation of a dominant negative form of lamin-A called progerin. Progerin also accumulates physiologically in normal ageing cells as a rare splicing form of lamin-A transcripts. From this perspective, HGPS cells seem to be good candidates for the study of the physiological mechanisms of ageing…
Role of Adenosine Receptors in Rare Neurodegenerative Diseases with Motor Symptoms
2021
: The approval of istradefylline, an adenosine 2A receptor (A2AR) antagonist, as an addon treatment in adult patients with Parkinson’s disease by the Food and Drug Administration (FDA) and European Medicines Agency (EMA), is the latest proof of the importance of the adenosinergic system in the nervous system. Adenosine is an endogenous purine nucleoside with a role as a modulator of both neurotransmission and the inflammatory response. As such, the expression pattern of the 4 adenosine receptors (A1R, A2AR, A2BR and A3R) and the extracellular adenosine levels have attracted great interest in the pathogenesis and possible treatment of rare neurodegenerative diseases with motor symptoms. The…
Disfunción endotelial en territorio arterial en pacientes jóvenes con enfermedad tromboembólica venosa
2015
La enfermedad tromboembólica venosa es la patología vascular más frecuente en gente joven, con 70 casos por cada 100.000 habitantes/año. En los últimos años se ha visto asociada al desarrollo de patología arterial, lo que aumenta aún más su morbimortalidad con una amplia repercusión socioeconómica. Este hecho ha sido objeto de diferentes estudios, sin que los mecanismos por los cuales se produce esta asociación entre patología venosa y arterial hayan sido del todo elucidados, sugiriéndose una etiopatogenia común principalmente basada en el estado inflamatorio que subyace en ambas patologías. Por ello, el objetivo del presente trabajo lo ha constituido el estudio de la inflamación vascular a…
A case report of double etiology of ecthyma gangrenosum
2019
Abstract Rationale: Ecthyma gangrenosum is a cutaneous infection, most commonly occurring during sepsis evolution with Pseudomonas aeruginosa on an immunocompromised background. There have been rare case reports in previously healthy children and rarer are the cases with double etiology. Patient concerns: We present the case of a female Caucasian patient, aged 1 year and 8 months, who developed severe sepsis during flu evolution with predominant respiratory and cerebral manifestations. On admission, at skin level, there was noticed a necrotic coccygeal ulceration (with rapid increasing dimensions 0.5/0.5 cm in 24 hours), and with the transformation from a dry necrosis in a sphacelus at the …
Shanghai Fever: Not Only an Asian Disease
2022
Objectives: To describe a case of Shanghai fever disease and to analyze other published reports in non-Asiatic countries, defining clinical characteristics and highlighting that this is not only an Asian disease. Study design: A computerized search without language restriction was conducted using PubMed and Scopus; all references listed were hand-searched to identify any other relevant literature. An article was considered eligible for inclusion in the systematic review if it reported cases with Shanghai fever described in non-Asiatic countries. Our case was also included in the analysis. Results: Ten articles reporting 10 cases of Shanghai fever disease were considered. Fever, diarrhea and…
Cirugía mínimamente invasiva en craneoestenosis
2006
En el presente trabajo se describe la experiencia en craneoestenosis con cirugía mínimamente invasiva, evaluando el diseño y eficacia de un nuevo craneotomo en cadáveres así como su aplicación clínica en un caso de sinostósis sagital con instrumentación endoscópica. Este procedimiento es sin duda un gran recurso en el tratamiento de las craneoestenosis brindando los beneficios de la cirugía mínimamente invasiva, eliminando la necesidad de grandes incisiones, disminuyendo el sangrado quirúrgico, reduciendo estancia hospitalaria y disminuyendo la morbilidad operatoria
Viscario vulgaris-Quercetum petraeae Stöcker (1965) in the Opawskie Mts (Eastern Sudetes)
2015
Abstract Results of phytosociological studies conducted in the southern part of Opole Silesia within the Sudetes mountain range in 2014-2015 are presented. The main aim of our research was to confirm the occurrence of Viscario vulgaris-Quercetum petraeae Stöcker 1965, which had previously been noted in Poland only within the Central Sudetes Foothills in Lower Silesia province. Two additional sites of this extremely rare in Poland plant association were confirmed, located within the Opawskie Mts in Opole province. The association develops on steep slopes, near rocky outcrops, on southern or western expositions at altitudes between 350 and 410 m a.s.l. All plots of the association consists of…
