Serum nitric oxide concentration in generalized chronic and aggressive periodontitis in the Mexican population is not related to the severity of the disease / La concentración de óxido nítrico en suero de pacientes con periodontitis agresiva y crónica generalizada no está relacionada con la gravedad de la enfermedad

Introduction: Periodontitis is an inflammatory disease that affects the supporting tissues of teeth, the effects of excess of nitric oxide, may contribute to the symptoms of periodontitis. Objective: To determine the serum nitric oxide concentration in generalized chronic and aggressive periodontitis patients and to compare it with a healthy subject group from the Mexican population. Materials and methods: A case and control study was performed. Sixty-nine individuals were recruited from the Clínica de Posgrado de Periodoncia of the Centro Universitario de Ciencias de la Salud, Universidad de Guadalajara, México. Patients with clinical features of generalized chronic periodontitis (GCP group, n=19), generalized aggressive periodontitis (GAP group, n=11), and a group of healthy subjects (HS group, n=39) were included in the study. Informed consent was obtained from each subject, and serum nitric oxide concentration was measured by an enzyme-linked immunosorbent assay. Results: Nitric oxide concentration in the study groups was greater in the GCP group (462.57 ± 16.57 µmol/L) than in the GAP group (433.84 ± 18.61 µmol/L) and the HS group (422.46 ± 12.07 µmol/L). A comparison using Student's t-test (one-tailed) between healthy subjects and generalized chronic periodontitis showed borderline significance (p<0.04), whereas no significant differences were observed in HS and GAP groups, with a p-value of 0.64, and the GAP vs. GCP p-value was 0.33. Conclusion: The serum nitric oxide concentration observed in the present study suggests that nitric oxide plays a major role in the inflammatory process, which cannot necessarily be linked to the severity of the disease and periodontal tissue destruction.

Introducción. La periodontitis es una enfermedad inflamatoria que afecta los tejidos de soporte dental; los efectos del exceso de óxido nítrico pueden contribuir a los síntomas de la periodontitis. Objetivo. Determinar la concentración de óxido nítrico en el suero de los pacientes con periodontitis agresiva y crónica generalizada, y compararla con la de individuos sanos de población mexicana. Materiales y métodos. Se trata de un estudio de casos y controles. Se incluyeron 69 individuos de la Clínica de Posgrado de Periodoncia del Centro Universitario de Ciencias de la Salud de la Universidad de Guadalajara. Se dividieron en tres grupos: pacientes con periodontitis crónica generalizada (GCP, n=19), pacientes con periodontitis agresiva generalizada (GAP, n=11) e individuos sanos periodontalmente (HS, n=39). Se obtuvo el consentimiento informado de todos los participantes. Se utililizó la prueba ELISA para medir la concentración de óxido nítrico en suero. Resultados. Las concentraciones de óxido nítrico observadas fueron mayores en el grupo GCP (462,57 ± 16,57 µmol/L) que en los grupos GAP (433,84 ± 18,61 µmol/L) y HS (422,46 ± 12,07 µmol/L). La comparación entre HS y GCP mediante la prueba estadística t de Student (una cola), mostró diferencias significativas (p<0,04), y no se observaron diferencias entre los grupos HS y GAP (p=0,64), ni entre GAP y GCP (p=0,33). Conclusiones. La concentración de óxido nítrico en suero, observada en el presente estudio, sugiere que el óxido nítrico desempeña un importante papel en el proceso inflamatorio, lo que no necesariamente está ligado a la gravedad de la enfermedad ni a la destrucción del tejido periodontal.

A Brazilian case of IFAP syndrome with severe congenital ichthyosis and limb malformations caused by a rare variant in MBTPS2 / Um caso brasileiro de síndrome IFAP com ictiose congênita grave e malformações de membros causadas por uma variante rara em MBTPS2

Abstract Objective: The classic triad, which defines IFAP syndrome, is ichthyosis follicularis, alopecia, and photophobia. It is a rare X-linked genetic disorder characterized by multiple congenital anomalies with variable severity, caused by pathogenic variants in the MBTPS2 gene, which encodes a zinc metalloprotease that is essential for normal development. This study aimed to report a case of a Brazilian patient with IFAP syndrome presenting skeletal anomalies, which is a rare finding among patients from different families. Case description: We describe a male proband with IFAP syndrome showing severe ichthyosis congenita, cryptorchidism, limb malformation, and comprising the BRESHECK syndrome features. Using whole-exome sequencing, we identified a rare missense variant in hemizygosity in the MBTPS2 gene, which had not been identified in other family members. Comments: This is the first diagnosis of IFAP syndrome in Brazil with a molecular investigation. The present case study thus expands our knowledge on the mutational spectrum of MBPTS2 associated with IFAP syndrome.

RESUMO Objetivo: A clássica tríade de ictiose folicular, alopecia e fotofobia dá nome a uma síndrome rara de origem genética com herança ligada ao cromossomo X (síndrome IFAP, do inglês Ichthyosis Follicularis, Alopecia, and Photophobia). Esta é uma síndrome caracterizada por múltiplas anomalias congênitas de expressividade variável, causada por variantes patogênicas no gene MBTPS2, que codifica uma zinco-metaloprotease essencial para o desenvolvimento normal humano. O objetivo deste estudo é apresentar o relato de caso de um paciente brasileiro com síndrome IFAP que apresentou anomalias esqueléticas, um achado raro entre os pacientes de diferentes famílias. Descrição do caso: Apresentamos um probando do sexo masculino com síndrome IFAP, com ictiose congênita grave, criptorquidia, malformação de membros e as características da síndrome de BRESHECK. Por meio do sequenciamento do exoma completo, identificamos uma variante rara do tipo missense, em hemizigose, no gene MBTPS2, não identificada em outros membros da família. Comentários: Este é o primeiro diagnóstico de síndrome IFAP no Brasil com investigação molecular. A análise molecular e a descrição de uma variante rara no gene MBPTS2 expandem nosso conhecimento sobre o espectro mutacional desse gene associado à síndrome IFAP.

"¿Qué opción les queda a las personas, más que nosotros?": Las funciones de los consultorios adyacentes a farmacias en la pandemia de covid-19 / "What choice do people have other than us?": The role of doctors' offices adjacent to private pharmacies in the Covid-19 pandemic

RESUMEN Con la llegada del coronavirus a México, los consultorios adyacentes a farmacias desempeñaron un rol preponderante en el diagnóstico, atención y prevención del covid-19. De acuerdo a las encuestas nacionales, entre el 11,7% y el 23% de las personas con síntomas de covid-19 se atendieron en uno. Por ello, este artículo busca identificar el papel de los consultorios adyacentes a farmacias (CAF) como sistema de salud privado que atendió a personas con síntomas de covid-19 en la ciudad de Oaxaca y describir y analizar los factores que influyeron en su utilización. Desde una metodología cualitativa, entre septiembre de 2020 y agosto de 2022 se entrevistó a 12 médicos y médicas y se aplicó un cuestionario a 59 personas usuarias de los consultorios adyacentes a farmacias del municipio de Oaxaca de Juárez. Asimismo se hizo una recopilación y análisis de fuentes secundarias. Entre los hallazgos, se describen sus funciones como frente de atención al covid-19 y a otras necesidades de salud que emergieron con la crisis sanitaria y se analizan los factores determinantes en las trayectorias de atención de personas usuarias de estos consultorios, como son el incremento en la percepción del riesgo y la desconfianza hacia los servicios públicos o hacia las estrategias implementadas por el gobierno federal.

ABSTRACT With the arrival of coronavirus in Mexico, doctors' offices adjacent to private pharmacies (DAPPs) played a major role in the diagnosis, care, and prevention of Covid-19, providing treatment for 11.7% to 23% of people with Covid-19 symptoms according to national surveys. Therefore, this article seeks to identify the role of DAPPs as a private health system providing care for patients with Covid-19 symptoms in the city of Oaxaca, and to describe and analyze the factors that influenced their utilization. Using a qualitative methodology, twelve physicians were interviewed and 59 users responded to a questionnaire at doctors' offices adjacent to pharmacies in the municipality of Oaxaca de Juárez between September 2020 and August 2022. Secondary data were also collected. Among the findings, the function of these offices at the front line of care for Covid-19 and other health needs that emerged with the public health crisis is described, and the determining factors in care trajectories of users that sought care there are analyzed, such as the increase in perception of risk and mistrust towards public services or strategies implemented by the federal government..

Cuidados paliativos: la visión del neurólogo en Uruguay / Palliative care from a neurologist's perspective in Uruguay / Cuidados paliativos: a visão do neurologista no Uruguai

Introducción: los cuidados paliativos (CP) han incluido en su abordaje patologías no oncológicas, sin embargo los criterios de inclusión de pacientes con enfermedades neurológicas avanzadas es aún un desafío. Objetivo: conocer la percepción de los neurólogos, residentes y posgrados sobre los CP. Método: se aplicó una encuesta en línea, ad hoc. Se exploró la percepción del profesional en cuatro áreas: experiencia de trabajo conjunto, enfermedades neurológicas pasibles de CP, criterios de derivación y autopercepción de la formación en CP. Resultados: se obtuvieron 60 respuestas, 73% de los neurólogos tenían más de 5 años de ejercicio. El 83% de los encuestados refirió haber compartido pacientes con profesionales de CP, el 87% afirmó que su experiencia fue positiva o muy positiva. El 53% consideró que la esclerosis lateral amiotrófica siempre debe recibir CP y alrededor de 80% evaluó la derivación de otras enfermedades sólo en etapas avanzadas. El principal criterio de derivación evocado fue la toma de decisiones anticipadas (66%), independientemente de los años de ejercicio. En relación a la autopercepción de la capacitación en el manejo del paciente con enfermedad neurológica avanzada al final de la vida, el 62% se percibió muy capacitado o aceptablemente capacitado. Conclusión: en esta primera aproximación de la perspectiva de los neurólogos del Uruguay con respecto a los CP, se destaca la necesidad de desarrollar guías de derivación y estrategias de trabajo conjunto para la asistencia integral de pacientes con enfermedades neurológicas pasibles de ser beneficiados por el enfoque de cuidados paliativos.

Introduction: palliative care (PC) has included non-oncologic conditions among its scope although inclusion criteria for patients with advanced neurological diseases continues to be challenging. Objective: to learn about the perception of neurologists, residents and postgraduates on palliative care. Method: an online, ad hoc survey was conducted. The survey explored the perception of professional in four areas: work experience in collaborative work, neurological conditions that could qualify for PC, criteria for referral and self-perception of palliative care training. Results: 60 replies were obtained. 73% of participants in the survey were neurologists with over 5 years of practice. 83% of surveyed physicians stated they had shared patients with PC professionals; 87% affirmed their experience had been positive or very positive. 53% found amyotrophic lateral sclerosis must receive PC in all cases and 80% considers the appropriateness of referring patients with other conditions only in advanced stages of the disease. The main criteria for referral mentioned was the making of anticipated decisions (66%), regardless of the years of practice. As to their self-perception of training in the handling of patients with advanced neurological disease at the end of life, 62% see themselves as very well prepared or satisfactorily prepared. Conclusions: in this first approach to the perspective of neurologists in Uruguay on palliative care, we stand out the need to create referral guidelines and strategies for collaborative work for the comprehensive handling of patients with neurological conditions that could qualify for benefiting from palliative care.

La gestión del conocimiento en instituciones de atención primaria de salud en el noroeste de México

Introducción: La búsqueda de la eficiencia en la atención a la salud de la población representa una prioridad para cada uno de los niveles de atención, por lo que es vital identificar los elementos que permitan una mejora continua en las instituciones. La gestión del conocimiento es utilizada para tal fin y se ha estudiado a la par de otras variables como: la cultura organizacional, el liderazgo y la disponibilidad y el uso de tecnologías de la información y comunicación. Objetivo: El objetivo del estudio fue analizar la relación de la gestión del conocimiento con estas variables en centros de atención primaria a las adicciones del noroeste de México. Métodos: Se aplicó un cuestionario (α = .977) a 80 profesionales de la salud que laboraban en esas instituciones. Se encontraron relaciones positivas, grandes y significativas entre la gestión del conocimiento y el liderazgo (r = .816, p <. 001) y entre la gestión del conocimiento y la cultura organizacional (r =. 802, p <. 001). Sin embargo, se encontró una correlación positiva y moderada con la variable tecnologías de la información y comunicación. Conclusiones: Se concluye que en los centros de atención primaria a las adicciones del noroeste de México la cultura organizacional y el liderazgo se consideran los factores más importantes para contribuir al éxito de la gestión del conocimiento, principalmente en la adquisición y la transferencia del conocimiento. Es importante considerar en estudios futuros los beneficios sociales y económicos de emplear la gestión del conocimiento en la toma de decisiones organizacionales.

Introduction: The search for efficiency in health care for the population signifies a priority for each level of care, so it is vital to identify the elements allowing continuous improvement in institutions. Knowledge management is used for this purpose and it has been studied along with other variables such as organizational culture, leadership and the availability and use of information and communication technologies. Objective: The objective of the study was to analyze the relationship of knowledge management with these variables in primary addiction care centers in Northwest Mexico. Methods: A questionnaire (α = .977) was applied to 80 health professionals who worked in these institutions. Positive, large and significant relationships were found among knowledge management and leadership (r = .816, p < .001) and among knowledge management and organizational culture (r = .802, p < .001). However, positive and moderate correlation was found with the information and communication technologies variable. Conclusions: It is concluded that in primary addiction care centers in Northwest Mexico, organizational culture and leadership are considered the most important factors to contribute to the success of knowledge management, mainly in the acquisition and transfer of knowledge. It is important to consider in future studies the social and economic benefits of using knowledge management in organizational decision making.

DNA methylation analysis identifies key transcription factors involved in mesenchymal stem cell osteogenic differentiation

BACKGROUND: Knowledge about regulating transcription factors (TFs) for osteoblastogenesis from mesenchymal stem cells (MSCs) is limited. Therefore, we investigated the relationship between genomic regions subject to DNA-methylation changes during osteoblastogenesis and the TFs known to directly interact with these regulatory regions. RESULTS: The genome-wide DNA-methylation signature of MSCs differentiated to osteoblasts and adipocytes was determined using the Illumina HumanMethylation450 BeadChip array. During adipogenesis no CpGs passed our test for significant methylation changes. Oppositely, during osteoblastogenesis we identified 2462 differently significantly methylated CpGs (adj. p < 0.05). These resided outside of CpGs islands and were significantly enriched in enhancer regions. We confirmed the correlation between DNA-methylation and gene expression. Accordingly, we developed a bioinformatic tool to analyse differentially methylated regions and the TFs interacting with them. By overlaying our osteoblastogenesis differentially methylated regions with ENCODE TF ChIP-seq data we obtained a set of candidate TFs associated to DNA-methylation changes. Among them, ZEB1 TF was highly related with DNA-methylation. Using RNA interference, we confirmed that ZEB1, and ZEB2, played a key role in adipogenesis and osteoblastogenesis processes. For clinical relevance, ZEB1 mRNA expression in human bone samples was evaluated. This expression positively correlated with weight, body mass index, and PPARγ expression. CONCLUSIONS: In this work we describe an osteoblastogenesis-associated DNA-methylation profile and, using these data, validate a novel computational tool to identify key TFs associated to age-related disease processes. By means of this tool we identified and confirmed ZEB TFs as mediators involved in the MSCs differentiation to osteoblasts and adipocytes, and obesity-related bone adiposity.

Conclusions: The prevalence of electrocardiographic abnormalities in hospitalized patients with the new coronavirus was higher compared to other series. History of ischemic heart disease and diabetes mellitus, in addition to age, were identified as independent predictors of electrocardiographic abnormalities in patients severely affected by the new coronavirus disease 2019.

La esquizofrenia: una mirada desde la ciencia, la tecnología y la sociedad

RESUMEN La esquizofrenia es probablemente el trastorno más enigmático y trágico que tratan los psiquiatras, y quizás, el más devastador. Se manifiesta en la juventud, por lo que los pacientes esquizofrénicos normalmente viven muchos años después del inicio de la enfermedad y continúan padeciendo sus efectos sin poder llevar una vida completamente normal. Se realizó una revisión bibliográfica para la cual se emplearon los recursos disponibles en Infomed, específicamente en las bases de datos EBSCO, SCIELO y libros de textos de autores cubanos y extranjeros. Se aplicó el método analítico-sintético y se revisaron 18 artículos científicos. Se expusieron los elementos que abordan el desarrollo histórico- cultural de la esquizofrenia desde la perspectiva de la ciencia, la tecnología y la sociedad. Se realizó esta revisión con el objetivo de contribuir al conocimiento sobre el desarrollo histórico cultural de la esquizofrenia, teniendo en cuenta las teorías que ha desarrollado el hombre a través de la ciencia para explicar la aparición de la enfermedad y la importancia de los factores sociales en la aparición, evolución y rehabilitación de este padecimiento.

ABSTRACT Schizophrenia is probably the most enigmatic and tragic disorder that psychiatrists treat, and perhaps the most devastating. It manifests itself in youth, so schizophrenic patients usually live many years after the onset of the disease and continue to suffer from its effects without being able to lead a completely normal life. A bibliographic review was carried out using the resources available in Infomed, specifically in the EBSCO and SCIELO databases and textbooks by Cuban and foreign authors. The analytical-synthetic method was applied and 18 scientific articles were reviewed. The elements that address the historical-cultural development of schizophrenia from the perspective of science, technology and society were exposed. This review was carried out with the aim of contributing to the knowledge about the historical cultural development of schizophrenia, taking into account the theories that man has developed through science to explain the appearance of the disease and the importance of social factors in the appearance, evolution and rehabilitation of this condition.

Práctica Basada en Evidencia en Adicciones: Conocimientos y Habilidades de Psicoterapeutas del Noroeste de México / Evidence-Based Practice in Addictions Area: Knowledge and Skills of Therapists from Northwestern Mexico

Resumen La Práctica Basada en Evidencia (PBE) es un proceso que inicia con el conocimiento de las evidencias disponibles y concluye con la selección de la mejor intervención para su implementación en escenarios clínicos lo cual impacta la efectividad de las intervenciones. Objetivo. Caracterizar el perfil de los terapeutas que laboran en 17 centros de tratamiento ambulatorio en adicciones del noroeste de México, además de sus conocimientos y habilidades en el uso de la PBE (fuentes de consulta, uso de manuales) y percepción de su autoeficacia. Método. Participaron 102 terapeutas, se contemplaron dos etapas: cuantitativa basada en la aplicación del CUTEA y cualitativa con aplicación de entrevista semi-estructurada, buscando contrastar las respuestas. Resultados. La mayoría de los participantes tuvo dificultad para describir el concepto de PBE, solo el 37.25% logró una adecuada definición sin embargo, reportaron altos niveles (95.91%) de autoeficacia para implementarla. En relación a las fuentes de consulta el 50% reportó utilizar cualquier buscador comercial en internet, mientras que el 46.08% referían usar los manuales de la institución. Al ingreso a su trabajo, no contaban con capacitación en adicciones ni en el área clínica. Discusión. Se aborda la necesidad del entrenamiento en la PBE y no solo en la implementación de tratamientos específicos.

Abstract Introduction. Evidence-Based Practice (EBP) is a process which starts with the knowledge of available evidence and concludes with the evaluation and selection of the best intervention for the implementation in clinical settings, this process impact the efficacy of the interventions. The variables which can impact on the EBP could be: personal and institutional variables and therapist skills and variables of the interventions. However, to make decisions in the clinical context, it has prevailed a position based on the risks and needs of the clients, which would justify using any treatment, regardless of its effectiveness, which makes the professional psychologist a passive subject who is dedicated only to implementing interventions that institutions request. Therefore, EBP demands that the psychologist be critical of the research and this allows the identification of the best evidence available and also must have the skills to adapt that evidence to their particular context. The objective is to characterize the profile of therapists working in 17 outpatient treatment centers in Mexico, as well as the skills related to the use of EBP (sources of consultation and use of manuals, transfer of knowledge to the population and other therapists) and perception of their self-efficacy. Method. This is a cross-sectional research in which 102 therapists participated. Two stages were considered: quantitative, based on the application of a questionnaire, and the second was qualitative, seeking to contrast the responses. Results. Most of the participants had difficulties in explaining EBP, but reported high levels of self-efficacy to implement it. At the beginning of their work, they had no training in addictions or in the clinical area. Discussion. The need for training in EBP from undergraduate studies is addressed so that future therapists will find it more natural to implement it in clinical settings, through the analysis of scientific articles and, if possible, its application.

Tromboelastografía para cirugía general / Thromboelastography for general surgery

Resumen: Las pruebas convencionales de coagulación evalúan el tiempo en que los factores de coagulación se activan en el plasma sanguíneo, el cual carece de componentes celulares, como enzimas y plaquetas que intervienen en el desarrollo de la hemostasia. La tromboelastografía (TEG) realiza un análisis in vitro de la relación entre plaquetas, enzimas, fibrinógeno y otros elementos de la coagulación de manera integral; por lo que se utiliza con mayor frecuencia en cirugías cardíacas, trasplantes y cirugías de malformaciones arteriovenosas, donde la pérdida sanguínea esperada es mayor a 40% del volumen sanguíneo circulante. La inclusión de la TEG en la valoración preanestésica permite evaluar la actividad plaquetaria en los pacientes que utilizan antiagregantes, como clopidogrel o ácido acetilsalicílico, a través del mapeo plaquetario (Platelet Mapping®). Cuando se presenta hemorragia en el período transanestésico, la TEG permite identificar de manera específica el tipo de tratamiento necesario para mejorar la coagulación o la transfusión de elementos formes de la sangre. La TEG permite realizar protocolos más sofisticados de terapia transfusional, lo que implica una disminución de las complicaciones asociadas con la politransfusión y, por ende, la disminución de costos, por lo que estos beneficios justifican el uso rutinario de la TEG para cualquier cirugía general.

Abstract: Conventional coagulation tests evaluate the time in which the coagulation factors are activated in the blood plasma, which lacks cellular components such as enzymes and platelets that are involved in the development of hemostasis. Thromboelastography (TEG) performs an in vitro analysis of the relationship between platelets, enzymes, fibrinogen, and other coagulation elements in an integral way; reason why it is used more frequently in cardiac surgeries, transplants, and surgeries of arteriovenous malformations, where the expected blood loss is greater than 40% of the circulating blood volume. The inclusion of TEG in the pre-anesthetic evaluation allows evaluating platelet activity in patients who use antiplatelets therapy, such as clopidogrel or acetylsalicylic acid, through platelet mapping (Platelet Mapping®). When bleeding occurs in the trans-anesthetic period, TEG specifically identifies the type of treatment necessary to improve coagulation or transfusion of formed blood elements. The TEG allows more sophisticated transfusion therapy protocols to be carried out, which implies a decrease in complications associated with polytransfusion and a reduction in costs, so these benefits justify the routine use of TEG for any general surgery.

Increase in direct costs for health systems due to lupus nephritis: the case of Colombia

ABSTRACT Objective Lupus nephritis is one of the most severe complications of systemic lupus erythematosus and it has been estimated that can occur in up to 60% of patients. Direct costs of lupus nephritis have not been studied in developing countries. This study aimed to describe lupus nephritis direct costs in Colombia. Methods Administrative data from two Colombian health maintenance organizations for 2014 and 2015 was obtained. An algorithm based on the International Statistical Classification of Diseases and Related Health Problems 10th revision codes was developed to identify patients with lupus nephritis and lupus nephritis under study. Results The average annual per-patient, all-claims, all-cause direct cost for lupus nephritis was US$ 12,624, 7.5 times higher than the average lupus patient without lupus nephritis. For lupus nephritis cases under study, estimated direct cost was US$ 3,664, 2 times higher than average lupus patient in Colombia. Difference in lupus nephritis patients is mainly accounted for the cost and frequency of procedures, exceeding by a factor of 5 the cost for durable medical equipment and the cost for drugs, respectively. Conclusion Lupus patients who progress to lupus nephritis stage increased seven-fold the average annual per-patient, all-claims, and all-cause direct cost for the Colombian health system.

La expresión del valor de la competitividad en la formación físico-deportiva del fútbol escolar / A expressão do valor da competitividade na formação físico-desportiva do futebol escolar / The expression of the value of competitiveness in the physical-sports training of school soccer

Resumen La competitividad suele considerarse un valor inherente a la sociedad en la que vivimos y se puede promover deliberadamente en el deporte escolar. Este estudio tiene por objetivo conocer las expresiones competitivas que implica en el fútbol escolar, mediante la observación participante, como reflexión al valor formativo que tiene la actividad. Se acompañan 10 equipos durante dos cursos escolares. El análisis de los resultados muestra que existen contradicciones entre la promoción de aprendizajes deportivos en condiciones de equidad y los resultados deportivos, que dependen de las aptitudes y capacidades individuales. Los niños capitalizan la rivalidad como la necesidad de ganar al oponente, lo que genera paradojas entre los apriorismos del deporte escolar, la socialización y sus aprendizajes. Este estudio concluye con la necesidad de promover sensibilidad educativa por los aprendizajes pedagógicamente deseables en complicidad con la participación de familias y agentes formativos.

Resumo A competitividade é geralmente considerada um valor inerente à sociedade em que vivemos e pode ser deliberadamente promovida nos esportes escolares. O objetivo deste estudo é conhecer as expressões competitivas que isso implica no futebol escolar, por meio da observação participante, como reflexo do valor educacional da atividade. Dez equipes são acompanhadas durante dois anos letivos. A análise dos resultados mostra que existem contradições entre a promoção da aprendizagem desportiva em condições justas e os resultados desportivos, que dependem das aptidões e capacidades individuais. As crianças capitalizam a rivalidade como necessidade de vencer o adversário, o que gera paradoxos entre os apriorismos do esporte escolar, socialização e seu aprendizado. Este estudo conclui com a necessidade de promover a sensibilização educacional para uma aprendizagem pedagogicamente desejável em cumplicidade com a participação das famílias e dos agentes formadores.

Abstract Competitiveness is often considered an inherent value in the society in which we live, and it can be deliberately promoted in school sports. This study aims to know the competitive expressions involved in school soccer as a reflection of the formative value of the activity, through participant observation. Ten teams are accompanied during two school years. The analysis of the results shows that there are contradictions between the promotion of equitable sports learning and sports results, depending on individual skills and abilities. Children capitalize on sports rivalry as the need to win against the opponent, which generates paradoxes between the apriorisms of school sports, socialization and their learning. This study concludes with the need to promote educational awareness of pedagogically desirable learning in complicity with the participation of families and training agents.

Anomalía de Ebstein y preeclampsia, asociación infrecuente: reporte de caso y revisión de la literatura / Ebstein's anomaly and preeclampsia, a rare association: case report and literature review

Resumen Se presenta el caso de una gestante con cardiopatía congénita no estudiada que acudió al servicio de urgencias en la semana 25 + 4 por palpitaciones, con evidencia de hipertensión arterial desde el ingreso. Los estudios diagnósticos revelaron anomalía de Ebstein, con gran compromiso de cavidades derechas y asociado a comunicación interauricular. También se documentó preeclampsia lejos del término, con restricción grave del crecimiento intrauterino. Durante la estancia hospitalaria, y ante negativa de la paciente a finalizar la gestación, desarrolló síntomas de congestión pulmonar por sobrecarga. Una vez falleció el feto in utero y después de inducir el parto, remitieron los síntomas cardiovasculares y se controló la hipertensión.

Abstract We present the case of a pregnant woman with previously undiagnosed congenital heart disease, who presented to the emergency department at week 25 + 4 due to palpitations, with evidence of arterial hypertension from admission. Diagnostic studies revealed Ebsteins anomaly, with great involvement of the right cavities and associated with atrial septal defect. Preeclampsia was also documented far from term, associated with severe intrauterine growth restriction. During the hospital stay and due to the refusal of the patient to end the pregnancy, she developed symptoms of pulmonary congestion due to overload, once the fetus died in utero and after inducing labor, the cardiovascular symptoms remitted and hypertension was controlled.

Trombosis muy tardía de stent metálico convencional: Un suceso inesperado

RESUMEN La trombosis muy tardía de stent es un fenómeno de baja frecuencia, pero de elevada morbilidad y mortalidad. Dentro de sus factores predisponentes se encuentran parámetros clínicos, anatómicos y relacionados con el procedimiento. Múltiples son los mecanismos fisiopatológicos que se plantean como responsables de la trombosis de stent. El tratamiento de esta complicación consiste en intentar restaurar el flujo del vaso lo antes posible. Se presenta el caso de un paciente con el diagnóstico de infarto agudo de miocardio con elevación del segmento ST secundario a trombosis muy tardía de stent metálico convencional (20 meses), tratado exitosamente mediante intervencionismo coronario percutáneo con dos stents liberadores de sirolimus.

ABSTRACT Very late stent thrombosis is a rare complication but with high morbidity and mortality. Predisposing factors include clinical, anatomical and procedure-related parameters. Many pathophysiological mechanisms are considered to be responsible for stent thrombosis. The treatment of this complication consists of attempting to restore blood flow as soon as possible. We present the case of an individual diagnosed with ST-segment elevation myocardial infarction after very late thrombosis of conventional bare metal stent (20 months). The patient was successfully treated by percutaneous coronary intervention with two sirolimus-eluting stents.

Nevo lipomatoso cutáneo superficial / Superficial cutaneous lipomatous nevus

RESUMEN El nevo lipomatoso cutáneo superficial es un nevo o hamartoma del tejido conectivo, idiopático, caracterizado por tumoraciones lobuladas del color de la piel, únicas o múltiples, con cierta predilección por la cintura pélvica; su aparición es poco frecuente. Histológicamente se destaca la presencia de células grasas maduras localizadas ectópicamente en la dermis. Se presentó un paciente de 40 años de edad con lesión en la piel de la región glútea derecha desde niño. Al examen dermatológico presentaba lesiones papulonodulares múltiples, de color de la piel, de tamaño variable, de consistencia blanda, localizadas en la nalga derecha. Se le realizó exéresis y biopsia de piel de lesión papulonodular de mayor tamaño, con diagnóstico histopatológico de nevo lipomatoso cutáneo superficial.

ABSTRACT A superficial cutaneous lipomatous nevus is an idiopathic connective tissue nevus or hamartoma characterized by single or multiple lobulated skin-colored tumors with a certain predilection for the pelvic girdle; its appearance is rare. Histologically, the presence of mature fat cells located ectopically in the dermis stands out. We present a 40-year-old male patient with a skin lesion of the right gluteal region since he was a child. On dermatological examination, he had multiple, skin-colored, papulonodular lesions of variable size and soft consistency located on the right buttock. Exeresis and skin biopsy of a larger papulonodular lesion were performed, with histopathological diagnosis of superficial cutaneous lipomatous nevus.

Tumor-like herpes simplex infection in an HIV patient

Abstract A 56-year-old male, HIV-positive, presented with a 3-day history of multiple indurated erythematous nodules with superficial and well-defined erosions on his right gluteus. Skin biopsy showed ballooning-necrotic keratinocytes and cultures were positive for herpes simplex 2. Genital herpes simplex infection recurrences may not be restricted to the anterior part of the genitalia and clinical presentation in the lumbar area or gluteus must be differentiated from varicella-zoster virus infection. Tumor-like presentation is a very rare manifestation of HSV cutaneous infection. It is important to take this morphological variant into consideration not to delay the diagnosis of a viral infection, especially in an immunosuppressed patient.
