RESUMO

RESUMEN Reportamos un caso de una mujer de 28 años, con síndrome nefrótico debido a glomerulonefritis por cambios mínimos 48horas después de la administración de la vacuna contra SARS-CoV2 de AstraZeneca. La paciente tuvo síndrome nefrótico idiopático en la infancia tratado empíricamente con corticoides y ciclosporina, en remisión completa desde los 9 años. Algunos reportes sugieren que determinadas enfermedades glomerulares podrían asociarse infrecuentemente a las vacunas.


ABSTRACT We report a case of a 28-year-old woman with minimal change disease secondary nephrotic syndrome 48 hours after the administration of the AstraZeneca SARS-CoV2 vaccine. The patient had suffered idiopathic nephrotic syndrome in childhood treated empirically with corticosteroids and cyclosporine, in complete remission from the age of 9. Some reports suggest that glomerular disease might appear infrequently associated to some vaccines.

RESUMO

Abstract Introduction: In high-volume trauma centers, especially in developing countries, penetrating cardiac box injuries are frequent. Although many aspects of penetrating chest injuries have been well established, video-assisted thoracoscopy is still finding its place in cardiac box trauma and algorithmic approaches are still lacking. The purpose of this manuscript is to provide a streamlined recommendation for penetrating cardiac box injury in stable patients. Methods: Literature review was carried out using PubMed/MEDLINE and Google Scholar databases to identify articles describing the characteristics and concepts of penetrating cardiac box trauma, including the characteristics of tamponade, cardiac ultrasound, indications and techniques of pericardial windows and, especially, the role of video-assisted thoracoscopy in stable patients. Results: Penetrating cardiac box injuries, whether by stab or gunshot wounds, require rapid surgical consultation. Unstable patients require immediate open surgery, however, determining which stable patients should be taken to thoracoscopic surgery is still controversial. Here, the classification of penetrating cardiac box injury used in Colombia is detailed, as well as the algorithmic approach to these types of trauma. Conclusion: Although open surgery is mandatory in unstable patients with penetrating cardiac box injuries, a more conservative and minimally invasive approach may be undertaken in stable patients. As rapid decision-making is critical in the trauma bay, surgeons working in high-volume trauma centers should expose themselves to thoracoscopy and always consider this possibility in the setting of penetrating cardiac box injuries in stable patients, always in the context of an experienced trauma team.

RESUMO

Resumen: Con la introducción de las vacunas de rotavirus Rotarix (RV1) o RotaTeq (RV5) en programas nacionales de vacunación de diversos países, surgió la preocupación de que la presión inmune generada condujera al aumento en la prevalencia de genotipos virales no incluidos en las vacunas, o bien del surgimiento de nuevas cepas que pudieran escapar a la respuesta inmune protectora inducida por la vacunación. La variación natural de los rotavirus ha hecho que sea muy difícil distinguir si el cambio en las cepas circulantes se debe a la presión selectiva impuesta por las vacunas o bien a la fluctuación natural de las cepas. Si acaso ha habido una presión selectiva, ésta ha sido hasta ahora baja. Sin embargo, es importante mantener la vigilancia epidemiólogica y poner atención al surgimiento de cepas resistentes a la inmunidad, en particular en países en desarrollo en los que se ha descrito una mayor diversidad viral.


Abstract: With the introduction of rotavirus vaccines Rotarix (RV1) or RotaTeq (RV5) in the immunization programs of an increasing number of countries, there is concern that the immune selection pressure induced will cause an increase in the prevalence of virus genotypes not included in the vaccine formulation, or to the appearance of novel rotavirus strains that could evade the protective immune response. The natural fluctuation of rotaviruses makes it difficult to distinguish if the change in the circulating strains is due to the vaccine selective pressure or to the natural diversity fluctuation of viruses. If there has been a selective pressure, it has been low so far. However, it is important to keep an epidemiological surveillance and pay attention to the emergence of strains that are resistant to the vaccine, in particular in those countries where the viral diversity has been shown to be higher.

RESUMO

El artículo presenta una estrategia de intervención sobre la violencia intrafamiliar a partir de una resignificación conceptual de la noción de violencia y el planteamiento de su función y sentido. La violencia se entiende como una fuerza de carácter simbólico inherente al sistema familiar, que cumple la función de mantener, modificar o sustituir los vínculos, teniendo como efecto su reorganización. El sentido es abordado bajo las acepciones de significación, propósito y orientación que constituyen el carácter discursivo bajo el cual se manifiesta la violencia. La intervención tiene como base un modelo analítico que privilegia la palabra de los sujetos. Mediante el análisis, ellos comprenderán de qué manera su historia familiar, los lugares y funciones de sus integrantes, el modo de desempeñarlos y sus expectativas sobre aquellos, favorecen la expresión de la violencia como un modo de hacer frente a la falla propia de todo sistema familiar.


The article presents a strategy for interventions on family violence, starting from a conceptual resignification of the notion of violence and a proposition regarding its function and meaning. Violence is conceived as a force of symbolic nature that is inherent to the family system and has the function of maintaining, modifying or substituting the bonds, thus resulting in their reorganization. Its sense is approached under the connotations of meaning, purpose, and orientation, that constitute the discursive nature which violence entails given its symbolic quality. The intervention is supported in an analytical model that privileges the subjects' words. Through the analysis, subjects will understand how their family history, the places and functions of its members, the way these are carried out, and their expectations about them, favor the expression of violence as a means of facing the failure of every familiar system.

RESUMO

Introducción Las fracturas pélvicas se asocian a sangrado arterial y/o venoso, ocasionando mortalidad elevada. El objetivo del estudio es diseñar, implementar y evaluar un protocolo para el tratamiento de fracturas pélvicas Materiales y métodos estudio prospectivo observacional, de pacientes con fractura pélvica que ingresaron a la clínica Medical. Variables: edad, sexo, arteria comprometida, lesión unilateral o bilateral, tipo de fractura pélvica (clasificación de Tile), indicación de la arteriografía, acceso uni o bilateral, éxito angiográfico, complicaciones del procedimiento, lesiones asociadas, mortalidad a 30 días, mecanismo de trauma, días de estancia en cuidado intensivo. Resultados 56 pacientes con fractura pélvica, 17 pacientes se llevaron a arteriografía pélvica por sospecha de sangrado, 14 pacientes tenían sangrado arterial, promedio de 36 años, las arterias más comúnmente lesionadas fueron la arteria hipogástrica, arteria sacra lateral y la arteria obturatriz. la mayoría de sangrados se asociaron a fracturas tipo C, las lesiones asociadas se encontraron en un 34% de casos, la indicación de la arteriografía fue inestabilidad hemodinámica al momento del ingreso, el control del sangrado se logró en el 86% de casos, la punción fue única en el 100% de casos, se requirió empaquetamiento pélvico 12% de casos. Discusión El trauma pélvico asociado a accidentes de motocicleta es común, el manejo multidisciplinario y la oportuna intervención del cirujano vascular es decisiva para el diagnóstico y tratamiento temprano de las lesiones vasculares pélvicas; la realización de un protocolo de manejo con un algoritmo de embolización mostró ser efectivo y seguro para el control del sangrado pélvico. Nivel de Evidencia: III


Background Pelvic fractures are frequently associated with arterial and / or venous bleeding, leading to high mortality (10 and 50%). Aim of study is to show our experience, based on an institutional protocol developed for the management of the patient with major pelvic trauma. Methods We conducted a prospective observational study for a 3 years period of time. The variables analyzed were: age, sex, artery involved, unilateral or bilateral lesion, type of pelvic fracture (Tile classification), indication of arteriography, unilateral or bilateral access, angiographic success, complications of the procedure, associated injuries, mortality at 30 days, trauma mechanism, days of stay in ICU and floor. Results We found 56 patients with pelvic fracture, 17 patients were taken to pelvic arteriography due to suspected bleeding, 14 patients had arterial bleeding, with an average age of 36 years, the arteries most commonly injured were the hypogastric artery, lateral sacral artery and the obturator artery, 50% of cases the bleeding was bilateral, the majority of bleeds were associated with type C fractures, associated lesions were found in 34% of cases, the indication of arteriography was hemodynamic instability at the time of admission, control of bleeding was achieved in 86% of cases (n: 15), the puncture was unique in 100% of cases (n: N: 14), pelvic packing was required in 2 patients (12%) Discussion Pelvic embolization for pelvic fracture is a safe and feasible procedure. A multidisciplinary approach and a high suspicion of pelvic arterial injury must be always in mind. Mortality in our trial was very low comparative with previous reports. Evidence Level: III

RESUMO

Resumen El objetivo del presente trabajo es analizar en Colombia las políticas públicas (leyes) relacionadas con la intervención de la violencia intrafamiliar (VIF) a partir de las concepciones de función y sentido de la violencia en la familia. Se hace una revisión crítica de las leyes (políticas públicas) sobre la VIF más importantes en el ámbito nacional colombiano, con el fin de identificar las características más comunes que impiden o dificultan un mejor abordaje del fenómeno violento y se esbozan alternativas que podrían superarlas. Se concluye que la forma en que se ha concebido la violencia intrafamiliar y la intervención que se ha derivado de ella ha dificultado comprender la función y el sentido que tiene la violencia dentro de los vínculos familiares y ha impedido intervenciones más eficientes en el interior de las familias.


Abstract The goal of this paper is to analyze the Colombian public policies (laws) related to the intervention on the interdomestic violence (IDV), starting for the conceptions of function and the meaning of domestic violence. The first section contains a critical review on legislation (public policies) about the IDV, more importantly in the national ambit of Colombia: law 294 of 1996 of the IDV law (reformed for the law 575 of 2000), and law 1257 of 2008, from which several laws have developed, regarding sensitization, prevention and sanction of different ways of violence and discrimination against women. Also, the penal code and the penal procedure were also reformed, and law 294 of 1996 and other dispositions were dictated. This public policies are reviewed critically, with the final purpose of identifying the common features that prevent or make the approach of the violent phenomenon more difficult. In this sense, the weaknesses of the public policies that exist in Colombia for the intervention on the IDV are found to be: 1.- state actions (public policies) imply the traditional conception that violence equals aggression; 2.- it is necessary and possible to eradicate the violence from the family ties. 3.- derived from the above, a sanction and penal emphasis are made as the best way to eradicate IDV; 4.- it is considered that the principal victim f this phenomenon it is the women, whence, in the public politics it is predominant the conception of a single gender, both in its conception and in its intervention; 5.- the conciliation processes are used as the best mechanism for supervision of the IDV, and finally, 6.- in public politics it is first the informative perspective, characterized for show a traditional conception of violence through psychosocial interventions, trainings and educational material; it concludes, in this section, that the understanding, explanation and intervention of the violent phenomenon has been dominated for a traditional conception of violence that, matching it with aggression or pretending its eradication, sustains the public politics strategies in the intervention of IDV of Colombia. In the second part f this paper work, and with the finality of showing the implication of the way that is conceived the violence present in the characteristics of the public politics here addressed is conceived the family as a composite system for elements of symbolic character that are articulated each from certain structure principles; said principles are: incompleteness of the system, lack of identity of the elements, covariance of the elements and dynamism of the system. The above, offers the basis for pointing the possible consequences of the law, that, as a public policies promote a particular way of contextualize and intervene IDV and allow to analyze the implications of the public policies from a renewed way of understanding the function and the sense of the violent phenomenon inside the family. This implications allow to consider: the consequences about public policies and its impact on IDV the compare violence and aggression, the impossibility of eradicate the IDV, it is consider that the penal sanction is insufficient in the IDV intervention, the consequences of the primacy of the perspective of a single gender in public policies on IDV, it is reflected that the conciliation processes do not allow to understand the complex role played by the IDV, and finally, it is considered necessary to overcome the merely informative perspective on the IDV; At the same time, alternatives are outlined that could overcome these weaknesses. It is concluded that the way in which IDV has been conceived and the intervention that has derived from it, has made it difficult to understand the function and meaning of violence within family ties and has prevented more efficient interventions within the family.

RESUMO

The exponential increase in the request for laboratory tests of 25-Hydroxyvitamin D or [25 (OH) D has ignited the alarms and generated a strong call for attention, since it may reflect deficiencies in the standardization of clinical practice and in the use non-systematic scientific evidence for decision-making in real life, which allows to analyze the indications of the test, its frequency, interpretation and even to assess the impact for health systems, especially when contrasted with the minimum or almost. No effects of the strategy of screening or supplying indiscriminately to the general population, without considering a comprehensive clinical assessment of risks and needs of people. From a purely public health impact point of view, the consequence of massive and unspecified requests is affecting most of the health systems and institutions at the global level. The primary studies that determined average population intake values have been widely used in the formulation of recommendations in Clinical Practice Guidelines, but unfortunately misinterpreted as cut points to diagnose disease and allow the exaggerated prescription of nutritional substitution. The coefficient of variation in routine tests to measure blood levels of 25 (OH) D is high (28%), decreasing the overall accuracy of the test and simultaneously, increasing both the falsely high and falsely low values. The most recent scientific evidence analyzes and seriously questions the usefulness and the real effect of the massive and indiscriminate practice of prescribing vitamin D without an exhaustive risk analysis. The available evidence is insufficient to recommend a general substitution of vitamin D to prevent fractures, falls, changes in bone mineral density, incidence of cardiovascular diseases, cerebrovascular disease, neoplasms and also to modify the growth curve of mothers' children. They received vitamin D as a substitute during pregnancy. The recommendations presented in the document are based on the critical analysis of current evidence and the principles of good clinical practice and invite to consider a rational use of 25 (OH) D tests in the context of a clinical practice focused on people and a comprehensive assessment of needs and risks. The principles of good practice suggest that clinicians may be able to justify that the results of the 25 (OH) D test strongly influence and define clinical practice and modify the outcomes that interest people and impact their health and wellness. Currently there is no clarity on how to interpret the results, and the relationship between symptoms and 25 (OH) D levels, which may not be consistent with the high prevalence of vitamin D deficiency reported. For this reason, it is suggested to review the rationale of the request for tests for systematic monitoring of levels of 25 (OH) D or in all cases where substitution is performed. Consider the use of 25 (OH) D tests within the comprehensive evaluation of people with suspicion or confirmation of the following conditions: rickets, osteomalacia, osteoporosis, hyper or hypoparathyroidism, malabsorption syndromes, sarcopenia, metabolic bone disease.

RESUMO

RESUMEN El descubrimiento de las acuaporinas, que constituyen una familia de proteínas integrales de membrana, ha supuesto un cambio con respecto a la comprensión del transporte de agua en las membranas biológicas. La más importante es la aquaporina 4 (AQP4) en la que nos centraremos a continuación, aunque existen otras dos acuaporinas la 1y la 9. Estas acuaporinas tienen una gran importancia en la fisiología del control del volumen celular y los mecanismos de control osmótico de las células. También en el control del flujo de glicerol y otros solutos. Además, las alteraciones en su funcionamiento se han relacionado con distintas enfermedades del sistema nervioso central como la neuromielitis óptica, el edema cerebral, la hipertensión intracraneal idiopática o la hidrocefalia crónica del adulto entre otras. Se realiza una revisión sobre este tema.


ABSTRACT The discovery of aquaporins, which constitute a family of integral membrane proteins, has meant a change with respect to the understanding of water transport in biological membranes. The most important is aquaporin 4 (AQP4) which we will focus on below, although there are two other aquaporins, 1 and 9. These aquaporins are of great importance in the physiology of cell volume control and osmotic control mechanisms of the cells. Also in the control of the flow of glycerol and other solutes. In addition, alterations in its functioning have been related to various diseases of the central nervous system such as neuromyelitis optics, cerebral edema, idiopathic intracranial hypertension or chronic hydrocephalus of the adult among others. A review is made on this topic.

RESUMO

Resumen La obesidad es un problema de salud pública mundial con un crecimiento alarmante para el cual no se han encontrado respuestas concluyentes en relación con sus causas. Entre las múltiples hipótesis que intentan explicar la epidemia, se encuentra la del genotipo ahorrador, propuesta por James V. Neel en 1962. Neel propone que las variaciones genéticas en comunidades cazadoras-recolectoras que fueron selectivamente favorables en el pasado -ya que permitieron enfrentar episodios de hambruna-, se convierten en una desventaja en la actualidad cuando los alimentos se han vuelto abundantes y son relativamente constantes. A pesar de tener muchos críticos, la conjetura de Neel permanece vigente. En este artículo se argumenta que la hipótesis del genotipo ahorrador apoya un enfoque explicativo basado en el determinismo biológico. Esta postura, al igual que la del determinismo social, subestiman el papel del individuo como un ente libre y responsable. Se hace la consideración de que la pandemia de obesidad no podrá ser explicada ni resuelta en tanto no ocurra un cambio drástico en el marco teórico prevalente en el que se incorpore el enfoque de que el individuo es un agente independiente, libre y responsable de sí mismo, con la capacidad potencial de colocarse por encima de su herencia biológica y del ambiente que lo rodea. No se rechaza la influencia de la biología y el entorno social en la conducta, pero se propone que esta se deriva de manera primordial de decisiones fundadas en el libre albedrío, el cual no está determinado ni biológica ni socialmente.


Abstract Obesity is a global public health problem with a concerning increasing rate and no conclusive answer related to its causes. The thrifty genotype, proposed by James V. Neel in 1962, is one of the many hypotheses that intend to explain the epidemic. Neel proposed that genetic variations in hunter-gatherer communities-which were selectively favorable in the past since they allowed to confront famine-are currently a disadvantage because food is plentiful and relatively constant. This conclusion remains valid despite being highly criticized. This review discusses that the hypothesis of the thrifty genotype supports an explicative approach based on biological determinism. This approach, such as social determinism, underestimates the role of individuals as free entities responsible for their own behavior. While a drastic change in the current theoretical framework occurs, in which individuals are considered as independent, free and self-responsible agents with the ability to overcome their heredity and their environment, the idea that the obesity pandemic cannot be explained or solved will be present. Although the influence of these elements in behavior is not rejected, it is proposed that behavior potentially and mainly comes from free will, which is neither biologically nor socially determined.

RESUMO

Introducción Las lesiones vasculares asociadas con fracturas por los accidentes de motocicleta son de alta energía y representan un desafío para los servicios de traumatología. El objetivo fue determinar el tipo de lesiones vasculares asociadas con accidentes de motocicleta, su tratamiento e implicaciones. Materiales y métodos Estudio retrospectivo descriptivo, en el cual se seleccionaron pacientes que tuvieron accidentes de motocicleta y solicitaron interconsulta al Servicio de Cirugía Vascular por sospecha de lesión en extremidades superiores o inferiores, en la Clínica Medical Proinfo de Bogotá, entre enero de 2015 y agosto de 2016. Se analizaron variables demográficas del tipo de lesión ortopédica, tipo de lesión vascular, arteria lesionada, tratamiento, indicación y complicaciones de la arteriografía, amputación y mortalidad. Resultados De los 81 pacientes, 32 presentaron lesión vascular mayor (39%), 21 (25%) se trataron con puente en injerto autológo, 5 por métodos intravasculares (6,1%), 7 requirieron amputación mayor por el traumatismo (8,6%) y hubo mortalidad en 3 pacientes (3,7%). Se encontró relación entre la lesión arterial y la amputación del miembro (p=0,02), el riesgo de amputación por la existencia de lesión vascular fue cinco veces más alto, comparado con los pacientes que no presentaron lesión vascular (OR: 6,6; IC95%: 1,7-25,3). Discusión Las lesiones vasculares asociadas con traumatismo por accidente de motocicleta corren un riesgo más alto de amputación mayor; el uso de arteriografía no mostró complicaciones asociadas ni retrasó el diagnóstico de los pacientes. El tratamiento integral del paciente es muy. importante para disminuir la morbimortalidad. Nivel de evidencia clínica Nivel IV.


Background Given the increase in motor vehicles in Bogota city in recent years, caused by lack of effective means of transportation and adequate roads; associated with recklessness of motorcyclists, a new type of patient has emerged, all members of trauma response must be coordinated to save the patient's life and injured limb. Motorcycle accidents are high energy traumas that in most cases affect limbs and acute vascular injuries that lead to amputation or late complications are frequent. Early diagnostic arteriography is very important to detect complex lesions and allows us a therapeutic planning. The aim of the study is to determine the type of vascular injuries associated with motorcycle accidents and their treatment. Materials and methods We performed a retrospective descriptive study, analyzing the patients who had motorcycle accidents. Variables were analyzed: Age, sex, type of orthopedic lesion, type of associated vascular lesion, lesioned artery, surgical or endovascular management, need for fasciotomies, indication and complications of arteriography, amputation and mortality at 30 days. Results A total of 81 patients, with 32 patients with major vascular injury (39%), 21 patients (25%) with a graft-graft, 5 patients by methods endovascular (6%), 7 patients required major amputation due to trauma (8.6%), mortality in 3 patients (3.7%). Discussion Early detection and specialized management of vascular injuries associated with motorcycles accidents is key for limb salvage. The incidence of amputation in spite of serious injuries is low. The integral management of the patient is very important to reduce morbidity and mortality. Level of evidence IV.

RESUMO

Resumen La otitis media aguda (OMA) es una enfermedad con alta prevalencia a nivel mundial principalmente en pacientes en edad pediátrica, debido a factores de riesgo propios del grupo etario, como los factores anatómicos y condiciones ambientales (asistencia a guardería, ausencia de lactancia materna y exposición al humo del tabaco, entre otros). El diagnóstico de certeza de la OMA es clínico y se basa en el inicio súbito del padecimiento, signos y síntomas de otitis media y líquido en el oído medio. El método más certero para evaluar la integridad de la membrana timpánica es la otoscopia simple, aunque la variante neumática es la más efectiva para establecer el compromiso en la movilidad de la membrana timpánica. Para la elección del tratamiento adecuado de la OMA se deben considerar diversos factores, entre ellos la edad del paciente, el estadio clínico, si existen tratamientos previos y el tiempo de evolución. La estrategia "esperar y ver" acompañada de analgésicos sistémicos por 48 a 72 horas disminuye la tasa de prescripción innecesaria de antibióticos en los casos de enfermedad no grave. El tratamiento antibiótico de primera línea, en el caso de que no haya mejoría con la primera estrategia o en forma directa es la amoxicilina a dosis de 80-90 mg/kg, y la combinación de amoxicilina con ácido clavulánico es el siguiente escalón cuando hay falla terapéutica con el primero, y una cefalosporina como la ceftriaxona, cuando se ha tenido falla terapéutica con amoxicilina y otro antimicrobiano previo. El tratamiento recomendado en pacientes alérgicos a la penicilina es claritromicina. La incidencia de complicaciones de la OMA es baja, éstas pueden ser: otitis media recurrente, hipoacusia conductiva, mastoiditis, parálisis del nervio facial, meningitis y absceso cerebral. Se recomienda realizar un seguimiento 3 a 6 meses después de un episodio sin complicaciones.


Abstract Acute otitis media (AOM) is a highly prevalent disease worldwide, primarily in pediatric patients due to the inherent risk factors in their age group, anatomical and environmental conditions such as day care attendance, lack of breastfeeding and exposure to cigarette smoke, among others. The definitive diagnosis of AOM is clinical and is based on a sudden onset of the disease, signs and symptoms of otitis media and fluid in middle ear. The most accurate method to evaluate the integrity of the patient's tympanic membrane is a simple otoscopy, although its pneumatic variant is the most effective tool to determinate loss of tympanic membrane mobility. Several factors, including the patient's age, clinical stage, previous treatment and time evolution should be considered in order to choose the right treatment for AOM. The "wait-and-see prescription" in addition to systemic analgesics for 48-72 hours reduces unnecessary antibiotic prescription in non-severe cases. Amoxicillin 80-90 mg/kg is the first-line antibiotic in case of no improvement with the first strategy. A combination of amoxicillin and clavulanate is the next step when first antibiotic therapy fails. A cephalosporin like Ceftriaxone is indicated in treatment failure with amoxicillin in addition to other previous antimicrobial. The recommended treatment in patients allergic to penicillin is clarithromycin. The incidence of complications of AOM is low, these include: recurrent otitis media, conductive hearing loss, mastoiditis, facial nerve paralysis, meningitis and brain abscess. Monitoring 3-6 months after an episode without complications is recommended.

RESUMO

Los tumores del estroma gastrointestinal (GIST) constituyen el tipo más frecuente de neoplasia mesenquimal del estroma gastrointestinal. Los casos que presentan características similares clínico-patológicas y moleculares que los GIST se ubican en los tejidos blandos del abdomen, y han sido denominados tumores del estroma extragastrointestinal (EGIST). Son infrecuentes y conocemos poco acerca de su pronóstico y manejo más adecuado. Presentamos el caso de una paciente diagnosticada de EGIST de localización en mesocolon con una evolución atípica. Este tipo de situaciones plantea un reto al diagnóstico diferencial a lo largo de todo el proceso y enfatiza la importancia de un manejo multidisciplinar.


Gastrointestinal stromal tumours (GIST) are the most common mesenchymal tumours of the gastrointestinal tract. Those GIST arising outside the gastrointestinal tract are called extra-gastrointestinal stromal tumours (EGIST) and share clinical, pathological and molecular features. They are very rare and very little is known about the correct management and prognosis of these neoplasms. The case is presented of a patient with a mesenteric EGIST and an unusual outcome. Its differential diagnosis is difficult, and the need for a multidisciplinary team approach is emphasised.

RESUMO

Gastric (GC) and breast (BrC) cancer are two of the most common and deadly tumours. Different lines of evidence suggest a possible causative role of viral infections for both GC and BrC. Wide genome sequencing (WGS) technologies allow searching for viral agents in tissues of patients with cancer. These technologies have already contributed to establish virus-cancer associations as well as to discovery new tumour viruses. The objective of this study was to document possible associations of viral infection with GC and BrC in Mexican patients. In order to gain idea about cost effective conditions of experimental sequencing, we first carried out an in silico simulation of WGS. The next-generation-platform IlluminaGallx was then used to sequence GC and BrC tumour samples. While we did not find viral sequences in tissues from BrC patients, multiple reads matching Epstein-Barr virus (EBV) sequences were found in GC tissues. An end-point polymerase chain reaction confirmed an enrichment of EBV sequences in one of the GC samples sequenced, validating the next-generation sequencing-bioinformatics pipeline.

RESUMO

Objetivo: Evaluar el comportamiento de diferentes factores deriesgo y del score de Framingham con la disminución de peso obtenida a través de cirugía bariátrica al año postoperatorio, en una clínica de obesidad durante los años 2008 y 2011. Se evaluaron las modificaciones en los factores de riesgo y riesgo global con el score de Framingham al año postoperatorio, de una cohorte retrospectiva de 209 pacientes de la clínica de obesidad en un hospital universitario; los cambios se expresan como porcentajes de disminución respecto al valor prequirúrgico, en las variables nominales. Resultados: El peso y el índice de masa corporal tuvieron una reducción del 48% y 38%, respectivamente; el score de Framingham se redujo de 12,4 a 7,6 (35%), es decir, pasó de riesgo intermedio a bajo (menor al 10%). Así mismo, se observó disminución en los valores de hemoglobina glicosilada (14,7%), colesterol total (11,59%), colesterol-LDL (7%) y triglicéridos (31,4%), elevación del colesterol-HDL (15,3%), suspensión del uso de insulina (18%), disminución del 20% del valor de la glucosa y la HbA1c, a menos de 5,7 en un 23% de pacientes con glicemia alterada en ayunas, y finalmente, reducción de la presión arterial sistólica (9,2%) y diastólica. Conclusiones: La cirugía bariátrica es una herramienta válida en pacientes en quienes han fallado otros métodos clínicos para disminuir de peso e índice de masa corporal. Con ésta, además, se logra una disminución en el score de Framingham y se mejora el control de comorbilidades.


Objective: To assess the behaviour of different risk factors and Framingham score with weight loss, obtained with bariatric surgery one year after surgery, in an obesity clinic during 2008 and 2011.Modifications of risk factors and global risk of the Framingham score one year after surgery, of a retrospective cohort of 209 patients of the obesity clinic at a University hospital. Changes are expressed as percentages of the decrease with regard to the pre-surgical values, in nominal values. Results: A 48% weight loss and 38% body mass index loss was observed, with a reduction of the Framingham score from 12.4 to 7.6 (35%), moving from an intermediate risk to a low risk (below 10%). A decrease of 14.7% in values of glycohemoglobin, 11.59% in total cholesterol, 7% of LDL cholesterol levels and 31.4% of triglycerides was observed, as well as a 15.3% raise in HDL cholesterol levels. 18% of patients with altered fasting glycaemia stopped taking insulin, glucose levels were reduced by 20% and A1c hemoglobin values were below 5.7 in 23% of the cases. Systolic pressure was reduced by 9.2%, same as the diastolic blood pressure. Conclusions: Surgery is a valid tool for patients were other clinical methods have failed, in order to lose weight and lower the body mass index, as well as reducing the Framingham score and improving the control of comorbidities.

RESUMO

Resumen:En la práctica médica pediátrica es frecuente encontrar a pacientes en circunstancias que representan un dilema ético para los profesionales de la salud. Un dilema corresponde a una situación en la que los preceptos morales o las obligaciones de similar obligatoriedad ética se encuentran en conflicto, de forma que cualquier solución posible al dilema es moralmente intolerable.Una revisión de la literatura permitió identificar diferentes modelos que abordan esta clase de dilemas. Se localizaron artículos utilizando las bases de datos Ebsco Host, ProQuest, Ovid e InMex, así como metabuscadores como metacrawler. Algunos de los modelos analizados fueron los siguientes: el Modelo de Anne Davis, el Método de Nijmegen, el Método de Diego Gracia, el Método Integral, el Modelo del Centro de Ética Médica de Bochum, el Modelo de Brody y Payton, el Modelo de Curtin y Flaherty, el Modelo de Thompson y Thompson, la Fórmula SAD, el Modelo de Javier Morata, el Modelo de Elaine Congress, el Modelo IFSW, el Modelo de Loewenberg y Dolgoff, el Modelo de la Ley Social, el Método DOER, el Modelo de Brommer, el Modelo de Corey y Callanan, el Modelo de Pope y Vasquez, el Modelo de Bush, Connell y Denney, el Modelo de Ferrell, Gresham y Fraedrich y el Modelo de Hunt y Vitell.Los criterios compartidos entre los diferentes modelos fueron los siguientes: a) la especificación del dilema ético; b) la descripción de los hechos a considerar; c) la definición de valores, principios y la postura ética que será tomada en consideración; y d) la toma de decisiones con la identificación de alternativas de solución. De acuerdo con la literatura revisada, se explican algunos modelos con el fin de identificar y ejemplificar elementos críticos que pudieran ser utilizados de manera práctica por los Comités de Ética Clínica u Hospitalaria en las instituciones de salud pediátrica en México.


Abstract:In pediatric medical practice it is common to encounter situations that represent a dilemma for health professionals. A dilemma occurs when ethical problems found in professional practice cause serious internal conflicts because they imply actions that contradict their colleagues, employees, or their own personal values and are classified as personal value conflicts, conflicts with other professionals, conflicts with clients and with organizations.A literature review allowed identifying different models to debate these types of dilemmas. The present work is a review of the search of scientific articles using databases such as Ebsco Host, ProQuest, Ovid, and InMex as well as metasearch tools such as metacrawler. The models found are as follows: Model of Anne Davis, Nijmegen method, Method of Diego Gracia, Integral method, Bochum Center Ethics model, Model of Brody and Payton, Model of Curtin and Flaherty, Model of Thompson and Thompson, SAD method, Model of Javier Morata, Model of Elaine Congress, IFSW model, Model of Loewenberg and Dolgoff, Ley Social Model, DOER method, Model of Brommer, Model of Corey and Callanan, Model of Pope and Vasquez, Model of Bush, Connell and Denney, Model of Ferrell, Gresham and Fraedrich, and Model of Hunt and Vitell.The key criteria shared in the different models are a) specifying the ethical dilemma, b) description of the facts, c) value definition, moral code and facts, decision making and d) identifying alternative solutions. In order to review the literature, some models are explained with the purpose of identifying and representing critical elements that clinical ethics committees could use in a practical manner in pediatric health institutions in Mexico.

RESUMO

La disección aórtica clásica es el síndrome aórtico más habitual. El común denominador de los síndromes aórticos agudos es la disrupción de la capa media, la presencia de hemorragia dentro de la pared (hematoma intramural), la separación extensa y progresiva de las capas en forma longitudinal (disección aórtica) y la disrupción de la pared debido a una placa ateromatosa que se ulcera (úlcera aterosclerótica penetrante). Los factores de riesgo asociados con mayor frecuencia son la hipertensión arterial (72%), la aterosclerosis (31%) y el antecedente de cirugía cardíaca previa. La clasificación de la disección aórtica aguda depende del sitio anatómico donde se encuentra el daño intimal y del segmento aórtico afectado. Las dos clasificaciones más usadas son los sistemas de DeBakey y Standford. El síntoma más común es el dolor torácico. En diferentes algoritmos se han usado la combinación de signos clínicos, herramientas no imaginológicas (electrocardiograma, los biomarcadores y la radiografía de tórax), y técnicas diagnósticas como el ecocardiograma, la tomografía axial computarizada, la aortografía y la resonancia magnética nuclear. Los síndromes aórticos agudos que comprometen la aorta ascendente son emergencias quirúrgicas. Conclusiones: la disección aórtica continúa siendo una enfermedad vascular catastrófica, a pesar del manejo con técnicas quirúrgicas y el advenimiento de nuevas intervenciones endovasculares. La sospecha clínica y la consulta al especialista en cirugía cardiovascular son pilares fundamentales en el abordaje terapéutico temprano de los pacientes afectados por los síndromes aórticos agudos.


Classic aortic dissection is the most common aortic syndrome. The common denominator of acute aortic syndromes is the disruption of the middle layer, the presence of hemorrhage within the aortic wall (intramural hematoma), longitudinal extensive and progressive separation of the layers (aortic dissection) and disruption of the wall due to ulceration of an atheromatous plaque (penetrating atheromatous ulcer). The risk factors most frequently associated with aortic dissection are hypertension (72%), atherosclerosis (31%) and a history of previous cardiac surgery. The classification of acute aortic dissection depends on the anatomical site of the intimal damage and the affected aortic segment. The two most widely used classifications are the DeBakey and Stanford systems. The most common symptom is chest pain. The combination of clinical signs, non-imaginological tools (electrocardiogram, biomarkers and chest radiography), and diagnostic techniques such as echocardiography, computed tomography, aortography and MRI have been used in different algorithms. Acute aortic syndromes that involve the ascending aorta are surgical emergencies. Conclusions: aortic dissection remains a catastrophic vascular disease, despite surgical management techniques and the advent of new endovascular interventions. Clinical suspicion and consultation with a cardiovascular surgeon are cornerstones in the early therapeutic approach for patients affected by acute aortic syndromes.

RESUMO

Introducción. La planta Solanum nudum es ampliamente usada en la medicina tradicional del Pacífico colombiano para tratar las fiebres y la malaria, o paludismo, y se ha convertido en una fuente de nuevas moléculas promisorias. Objetivo. Evaluar el efecto citotóxico y daño genético de extractos estandarizados de S. nudum en diferentes modelos celulares. Materiales y métodos. A 66 extractos estandarizados de S. nudum se les evaluó la actividad anti- Plasmodiumin vitro en dos cepas de Plasmodium falciparum, una sensible (NF54) y otra resistente (FCB2) a la cloroquina, y la citotoxicidad en células U937 y HepG2. Se seleccionaron los extractos que presentaron actividad anti- Plasmodium y baja toxicidad, y se les estimó su efecto hemolítico en eritrocitos sanos O + , el efecto mutagénico en las cepas TA98 y TA100 de Salmonella Typhimurium y el efecto genotóxico en células U937. Resultados. Se seleccionaron cinco extractos como promisorios (28MA1, 29MA1, 51MA1, 55MA1 y 61MA1), los cuales fueron activos en las cepas de P. falciparum con concentración inhibitoria 50 (CI 50 ) entre 9,8 y 54,8 µg/ml. El extracto 29MA1 fue el más selectivo para Plasmodium, con índice de selectividad de 4,4 y 14,5 para las células U937 y HepG2, respectivamente. En ningún extracto se observó efecto hemolítico a 250 µg/ml, no causaron mutaciones en las cepas TA98 y TA100 de S.Typhimurium, ni generaron efectos genotóxicos en células U937. Conclusiones. La utilización de extractos estandarizados de S. nudum contribuye con los trabajos encaminados al desarrollo de una nueva formulación farmacéutica para tratar la malaria a partir de productos naturales.


Introduction. The plant Solanum nudum (Solanaceae) is extensively used for the treatment of malaria-related symptoms in traditional medicine practices in the Colombian Pacific. Recently, it has become a significant source of promising new molecules for developing a pharmaceutical malaria treatment. Objective. This research aimed to evaluate the cytotoxic effect and the genetic damage of standardized extracts of S. nudumon different cells. Materials and methods. Sixty six standardized S. nudum extracts were used, evaluating cytotoxicity in U937 and HepG2 cells and the antiplasmodial activity using both a chloroquine-sensitive (NF54) and a chloroquine-resistant (FCB2) strain. The hemolytic effect on healthy O + erythrocytes, the mutagenic effect on S.Typhimurium TA98 and TA100 strains and the genotoxic effect on U937 cells were evaluated. The extracts that displayed both antiplasmodial activity and low toxicity were selected. Results. Five extracts were selected: 28MA1, 29MA1, 51MA1, 55MA1 and 61MA1. These extracts were active against P. falciparum with IC 50 between 9.8 and 54.8 µg/ml and selectivity indexes were calculated between 0.9 and 4.4, the latter for 29MA1. Also, no hemolytic effects in healthy O + erythrocytes were shown at a concentration of 250 µg/ml, nor did they cause mutations in the TA98 and TA100 strains or generate genotoxic effects in U937cells. Conclusion. The use of standardized extracts of S. nudum could contribute to the body of work aimed at developing a new pharmaceutical treatment for malaria using natural products.
