ABSTRACT

Thirty-five peptides selected from functionally-relevant SARS-CoV-2 spike (S), membrane (M), and envelope (E) proteins were suitably modified for immunising MHC class II (MHCII) DNA-genotyped Aotus monkeys and matched with HLA-DRß1* molecules for use in humans. This was aimed at producing the first minimal subunit-based, chemically-synthesised, immunogenic molecules (COLSARSPROT) covering several HLA alleles. They were predicted to cover 48.25% of the world's population for 6 weeks (short-term) and 33.65% for 15 weeks (long-lasting) as they induced very high immunofluorescent antibody (IFA) and ELISA titres against S, M and E parental native peptides, SARS-CoV-2 neutralising antibodies and host cell infection. The same immunological methods that led to identifying new peptides for inclusion in the COLSARSPROT mixture were used for antigenicity studies. Peptides were analysed with serum samples from patients suffering mild or severe SARS-CoV-2 infection, thereby increasing chemically-synthesised peptides' potential coverage for the world populations up to 62.9%. These peptides' 3D structural analysis (by 1H-NMR acquired at 600 to 900 MHz) suggested structural-functional immunological association. This first multi-protein, multi-epitope, minimal subunit-based, chemically-synthesised, highly immunogenic peptide mixture highlights such chemical synthesis methodology's potential for rapidly obtaining very pure, highly reproducible, stable, cheap, easily-modifiable peptides for inducing immune protection against COVID-19, covering a substantial percentage of the human population.

ABSTRACT

Malaria outbreaks have been reported in recent years in the Colombian Amazon region, malaria has been re-emerging in areas where it was previously controlled. Information from malaria transmission networks and knowledge about the population characteristics influencing the dispersal of parasite species is limited. This study aimed to determine the distribution patterns of Plasmodium vivax, P. malariae and P. falciparum single and mixed infections, as well as the significant socio-spatial groupings relating to the appearance of such infections. An active search in 57 localities resulted in 2,106 symptomatic patients being enrolled. Parasitaemia levels were assessed by optical microscopy, and parasites were detected by PCR. The association between mixed infections (in 43.2% of the population) and socio-spatial factors was modelled using logistic regression and multiple correspondence analyses. P. vivax occurred most frequently (71.0%), followed by P. malariae (43.2%), in all localities. The results suggest that a parasite density-dependent regulation model (with fever playing a central role) was appropriate for modelling the frequency of mixed species infections in this population. This study highlights the under-reporting of Plasmodium spp. mixed infections in the malaria-endemic area of the Colombian Amazon region and the association between causative and environmental factors in such areas.

ABSTRACT

PURPOSE: The objective was to determine the dimensional impact, on the occlusal and articular level, of the gap produced in the lingual plate from symphyseal fractures, correlated with the dimensional change in the posterior mandibular width. MATERIALS AND METHODS: We performed an observational experimental study based on 30 computed tomography scans of patients treated by the Maxillofacial Surgery Service, Hospital Clínico Mutual de Seguridad, Santiago, Chile, between 2012 and 2016. The inclusion criteria were jaws without evidence of fractures or pathology, with an absence of orthodontic appliances, and with complete dentition to the first mandibular molar. By use of Digital Dental Service 3-dimensional planning software (DDS-Pro; Digital Dental Service, London, UK), a vertical mandibular fracture was made, leaving lingual gaps of 1, 2, and 3 mm, and the dimensional changes were recorded with regard to the posterior facial width. RESULTS: The mandibular height did not vary with regard to the lingual gap; the mandibular length was inversely proportional to the lingual gap; and the intermolar, intergonial, and intercondylar distances were directly proportional to increases in the lingual gap. CONCLUSIONS: The larger the lingual gap, the shorter the mandibular length and the larger the mandibular transverse dimensions. Special attention must be paid to the occlusal and articular level.

ABSTRACT

Objetivo. La reducción de la fractura aislada de arco cigomático (FAAC) es, habitualmente, realizada a distancia mediante un abordaje temporal de Gillies. No se recomienda una reducción abierta por la gran morbilidad y complicaciones asociadas. Sin embargo, al realizar una reducción cerrada, es muy difícil precisar si fue satisfactoriamente realizada. El objetivo de este trabajo es determinar si la adquisición de imágenes intraoperatorias con un arco en C para evaluar la reducción de FAAC es una técnica útil en el tratamiento de dichas fracturas. Métodos. Nuestra hipótesis es que utilizar un arco en C para adquirir imágenes intraoperatorias reduce la necesidad de una segunda cirugía. Entre los años 2009 y 2012, 50 pacientes que fueron diagnosticados con FAAC y que requerían tratamiento quirúrgico fueron distribuidos aleatorizadamente en 2 grupos: 25 pacientes en un grupo experimental en que se realizaba reducción de la fractura y corroboración inmediata de un adecuado resultado con arco en C intraoperatoriamente y 25 pacientes en un grupo control en que se realizaba reducción de la fractura con imagen de control posterior a la cirugía. Resultados. Los resultados mostraron que no hubo diferencias significativas entre ambos grupos (p=0,05). Sin embargo, existió la ventaja de poder reducir de nuevo la fractura inmediatamente si el resultado no era satisfactorio en el grupo experimental. Conclusión. A pesar de que los resultados no son estadísticamente significativos, los autores recomiendan realizar imágenes intraoperatorias en aquellas zonas de las que no se tiene certeza de la reducción (AU)


Purpose. Isolated zygomatic arch fractures (IZAF) are habitually reduced at a distance, via a temporal approach. Open reductions are not recommended due to the associated morbidity and complications. However, performing closed reductions makes it difficult to determine whether it was done satisfactorily. This study aims to determine whether the acquisition of intraoperative images with a C-arm to evaluate IZAF reductions is a useful technique in treating such fractures. Methods. Our hypothesis is that acquiring intraoperative images with a C-arm reduces the need for a second surgery. Between 2009-2012, 50 patients who were diagnosed with IZAF requiring surgery were randomly distributed into 2 groups: 25 patients in the experimental group, where fracture reduction was performed and immediately corroborated intraoperatively for an adequate result using a C-arm; 25 patients were assigned to a control group where the fracture reduction was controlled with post-surgery imaging. Results. The results did not reveal significant differences between both groups (P=.05). Nevertheless, the experimental group had the advantage of being able to immediately reduce the fracture again if the result was unsatisfactory. Conclusions. Despite the fact that the results are not statistically significant, the authors recommend undertaking an intraoperative imaging analysis in areas where we are not certain of the reduction (AU)

ABSTRACT

Objetivo. Realizar un análisis retrospectivo de la utilización del acceso retrocaruncular para abordar las reconstrucciones orbitarias de la pared medial. Adicionalmente, la técnica para realizar este acceso es descrita. Material y método. La muestra fue seleccionada de la población derivada al Servicio de Cirugía Maxilofacial del Hospital Clínico Mutual de Seguridad C.Ch.C (Santiago, Chile) para el tratamiento de fracturas orbitarias producto de traumatismo entre el 1 de enero del 2011 y el 31 de diciembre del 2014. Criterios de inclusión: mayores de 18 años con fracturas aisladas de pared medial de órbita o combinadas con piso orbitario, uni o bilaterales, con indicación quirúrgica, abordadas mediante acceso retrocaruncular y con un seguimiento mínimo de 6 meses. Criterios de exclusión: fractura de techo y/o pared lateral de la órbita. Resultados. Ciento sesenta y ocho órbitas fueron operadas durante el periodo indicado; 27 órbitas con fracturas de pared medial abordadas mediante acceso retrocaruncular con extensión transconjuntival y cantotomía lateral fueron incluidas en este estudio; 6 de ellas eran fracturas de pared medial puras y las 21 restantes combinadas con piso. Exceptuando un caso que requirió reconstrucción tardía con implante de titanio customizado, todas las reconstrucciones de órbita fueron exitosas en la primera cirugía. Salvo un paciente que desarrolló un granuloma conjuntival en relación con la carúncula, ningún paciente tuvo complicaciones en relación con el acceso retrocaruncular. Conclusiones. La técnica para el acceso retrocaruncular presentada otorga un seguro, amplio y directo acceso a la pared medial para realizar reconstrucción de la órbita, obteniendo óptimos resultados estéticos y funcionales con mínimas complicaciones (AU)


Objective. To present a retrospective analysis of the use of retrocaruncular approach to access medial orbital wall reconstruction. Additionally, the technique for performing this access is described. Material and method. The sample for this study was chosen from the population of patients referred to the Maxillofacial Surgery Service at the Hospital Clínico Mutual de Seguridad C.Ch.C (Santiago, Chile) for the treatment of orbital fractures between 1st of January 2011 and 31st of December 2014. Subjects eligible for study inclusion had age ≥18, either isolated medial orbital wall fractures or combined with floor fractures, uni or bilateral, with surgical indication, accessed with retrocaruncular approach and 6 month of follow up at least. Exclusion criteria: roof and/or lateral orbital wall fractures. Results. Between January 2011 and December 2014, a total of 168 orbits were treat. 27 orbits with medial wall fractures were accessed with retrocaruncular approach with transconjunctival extension and lateral canthotomy and were included in this study. Of them, 6 were pure medial wall fractures and 21 combined with floor fractures. Except for one case that required delayed reconstruction with customized orbital implant, all orbital reconstructions were successful in the first surgery. Except for a patient who developed a conjunctival granuloma in relation to the caruncle, no patients had complications related to retrocaruncular access. Conclusiones. The retrocaruncular approach presented allows asafe, wide and direct access for repairing medial orbital wall fractures with optimal aesthetics results and minimal functional complication (AU)

ABSTRACT

PURPOSE: Isolated zygomatic arch fractures (IZAFs) are habitually reduced at a distance, via a temporal approach. Open reductions are not recommended due to the associated morbidity and complications. However, performing closed reductions makes it difficult to determine whether it was done satisfactorily. This study aims to determine whether the acquisition of intraoperative images with a C-arm to evaluate IZAF reductions is a useful technique in treating such fractures. METHODS: Our hypothesis is that acquiring intraoperative images with a C-arm reduces the need for a second surgery. Between 2009 and 2012, 50 patients who were diagnosed with IZAF requiring surgery were randomly distributed into two groups: 25 patients were in the experimental group, where fracture reduction was performed and immediately corroborated intraoperatively for an adequate result using a C-arm, and 25 patients were assigned to a control group where the fracture reduction was controlled with post-surgery imaging. RESULTS: The results did not reveal significant differences between both groups (p = 0.5). Nevertheless, the experimental group had the advantage of being able to immediately reduce the fracture again if the result was unsatisfactory. CONCLUSIONS: Despite the fact that the results are not statistically significant (p = 0.5), the authors recommend undertaking an intraoperative imaging analysis in areas where we are not certain of the reduction.

ABSTRACT

Objetivo: Recopilar información del traumatismo maxilofacial, específicamente en pacientes adultos, en el periodo de 3 años en un centro chileno de referencia de traumatismos. Materiales y métodos: Se realizó un estudio descriptivo retrospectivo en todos los casos de fracturas faciales que asistieron al Servicio de Cirugía Maxilofacial del Hospital Clínico Mutual de Seguridad C.Ch.C., Santiago de Chile, en el periodo de 3 años (enero de 2009-diciembre de 2011). Fueron analizadas las variables y distribución de género, edad, tipo, frecuencia de cada fractura y causa del traumatismo. Resultados: La población estudiada consistió en 283 pacientes, 259 (91,5%) hombres y 24 (8,5%) mujeres con un promedio de edad de 40,5 (SD: ± 20,5) años. En 499 sitios de fractura las fracturas cigomáticas fueron la localización más prevalente en ambos géneros (48%), seguidas de las fracturas orbitarias (27,2%) y en tercer lugar las fracturas mandibulares (21,2%). La parte de la cara más afectada fue el tercio medio. Los traumatismos por accidente de tránsito fueron la causa más común (39,2%); la gran mayoría de estos fueron por accidente automovilístico. Discusión: Los resultados mostrados en este artículo están en línea con la literatura, y el análisis de este reporte provee importante información para el diseño de planes de prevención de riesgos, especialmente para desarrollar medidas en el área del tránsito (AU)

ABSTRACT

PURPOSE: Post-traumatic oromandibular dystonia (PTOD) is a disorder whose symptoms can include bruxism, muscle pain, and involuntary muscle contraction, among others. The use of onabotulinumtoxinA (ObT-A) is helpful in controlling the symptoms of patients with PTOD. The aim of this study was to evaluate the use of ObT-A in the treatment of PTOD. MATERIALS AND METHODS: In this prospective case-series study, the population consisted exclusively of patients diagnosed with PTOD, without distinction by age or gender, from January 2007 to December 2010. The patients were diagnosed with PTOD and treated with ObT-A infiltration (primary predictor) at the Department of Maxillofacial Surgery at the Hospital Clínico Mutual de Seguridad (Santiago, Chile). The primary outcome variables were bruxism, muscle pain, and involuntary muscle contraction. The data were obtained through questionnaires registered in tables at each control. Systat 13.1 was used for statistical analysis. The statistical test used to compare patients' evolution over time was the test of signs. RESULTS: Thirty male patients 18 to 65 years old diagnosed with PTOD were treated with ObT-A infiltrations. The signs and symptoms associated with oromandibular dystonia (bruxism, muscle pain, and involuntary muscle contraction) were decreased in all patients after ObT-A infiltrations. CONCLUSIONS: The positive results and the absence of complications recommend the use of the infiltration protocol presented in this study for the treatment of PTOD.

ABSTRACT

Objetivo: El objetivo de este estudio fue ver la prevalencia y la evolución del tratamiento en las fracturas radiculares en pacientes adultos laboralmente activos que sufrieron un trauma dentoalveolar y presentar un protocolo de tratamiento distinto basándose en el pronóstico a largo plazo según nuestros porcentajes de éxito. Materiales y métodos: Se realizó una revisión retrospectiva de los casos de trauma dentoalveolar y específicamente de fracturas radiculares que acudieron a la Unidad de Cirugía Maxilofacial del Hospital Clínico Mutual de Seguridad (Santiago Chile) durante un an˜ o en el periodo de mayo de 2009 hasta mayo de 2010. Resultados: Se registró un total de 894 casos, de los cuales 56 (6,3%) casos tuvieron el diagnóstico de fractura radicular. Hasta el momento de la revisión todos los implantes presentaron una tasa de éxito del 100% a diferencia del tratamiento endodóntico en conjunto con la ferulización semirrígida que mostró un 20% de éxito. El 80% restante resultó en una pérdida dentaria y posterior rehabilitación con implante dental. Conclusiones: Nosotros pensamos que la reposición dentaria después de una fractura radicular mediante implantes dentales es una excelente opción y que debe ser recomendada (AU)


Objective: The aim of this study is to observe the prevalence, etiology, diagnosis, treatment and outcome of root fractures in adult patients who suffered a dentoalveolar trauma. We present a different treatment protocol for root fractures in adult patients, according to our success rates, as well as the prognosis and long-term outcomes. Materials and methods: In a retrospective study was conducted by reviewing the records of all patients with dentoalveolar trauma and root fractures between May 2009 and May 2010 in the Department of Oral and Maxillofacial surgery, Hospital Mutual de Seguridad C.Ch.C., Santiago de Chile. Results: A total of 894 dentoalveolar trauma cases were recorded, of which 56 (6.3%) were root fractures. In terms of outcome, implants had a 100% success rate to the date, instead root canal treatment and flexible splint showed only a 20% of success, because 80% progressed to tooth loss and dental implant. Conclusions: We believe that dental replacement of tooth loss after root fracture by dental implant is an excellent option and should be recommended (AU)

ABSTRACT

Introducción: El Día Mundial del Riñón es una iniciativa de la Sociedad Internacional de Nefrología y la Federación internacional de Fundaciones Renales para disminuir problemas relacionados con la enfermedad renal y crear conciencia sobre este tema. En 2012, el Ministerio de Desarrollo Humano de Formosa, Argentina, organizó una evaluación clínica gratuita dirigida especialmente a quienes supieran que presentaban algún factor de riesgo para enfermedad renal. Método: Durante una semana, en 4 consultorios se entrevistó a los participantes. Se tomó nota de los antecedes, se midieron los siguientes parámetros: presión arterial, circunferencia abdominal, niveles de urea, creatinina y glucemia. Se realizaron ecografía renal y análisis de orina. Los resultados se analizaron estadísticamente. Resultados: Se tomaron los datos de 63 personas. Media de edad; 49.8 ± 14.2. Cuarenta y tres (68.3%) participantes informaron tener antecedentes patológicos. Catorce (22%) muestras de orina y 16 (25%) ecografías renales resultaron con indicadores de patología. Se detectaron 24 personas (38.1%) con HTA, 9 lo desconocían, 2 con diabetes no informada. Treinta y cuatro(54%) sujetos mostraron MDRD <- 80. Treinta y siete (58%) participantes con circunferencia abdominal mayor a los valores recomendados. Diez (15.9%) hombres presentaron creatinina >- 1,40/mg/dl y 3(4.8%) nivel de glucemia >- 126 mg/dI. Conclusión: Treinta y siete pacientes fueron invitados a consultar con un especialista por presentar indicador de insuficiencia renal o factor de riesgo. Se deberían repetir y ampliar estas acciones para diseñar programas sanitarios, detectar la enfermedad renal y crear conciencia sobre hábitos de vida saludable.


World Kidney Day is an initiative of the International Society of Nephrology and the International Federation of Kidney Foundations to reduce the impact of kidney disease and raise awareness about it. In 2012, the Ministry of Human Development of Formosa, Argentina, organized a free screening especially targeted to those who thought could had some risk factor for kidney disease. Methods: During the Kidney week 2012, 3 nephrologists and 1 general physician interviewed the participants. Blood pressure and abdominal circumference were measured; urine and blood samples were evaluated for urea, creatinine and glycaemia levels, and renal echography was performed. Results were statistically analyzed. Results: Data from 63 participants were used in this study. Mean age: 49.8 years ± 14.2. 14 (22%) urine samples showed pathological signs and 16(25%) renal ultrasound tests were pathological. 24(38.1%) presented HTA, 9 people were unaware of this condition. We found 2 cases of uninformed diabetes. 34(54%) participants had MDRD <-80 and 37(58.7%) had abdominal circumference above safe parameters. Ten men (15.9%) had creatinine >- 1,40/mg/dl and 3(4.8%) participants had glucose level >- 126 mg/dl. Conclusion: Thirty seven participants were referred to specialist. Screening should be carried out for early detection of kidney disease, to obtain information for the design and implementation of public health programs and to promote healthy habits.

ABSTRACT

La ley nacional Nº 18.335 señala que: “Toda persona tiene derecho a acceder a una atención integral que comprenda todas aquellas acciones destinadas a la promoción, protección, recuperación, rehabilitaciónde la salud y cuidados paliativos”. Está ampliamente recomendado en la literatura que todos los profesionales de la salud que asisten niños deberían contar con los conocimientos, actitudes y destrezas básicas para ofrecer una atención en clave de cuidados paliativos (CP) a quienes lo necesiten, en todos los escenarios de atención, en forma personal o en equipo. La presente pauta fue elaborada por la Unidad de cuidados paliativos pediátricos del CHPR, en base a las recomendaciones internacionales y a la propia experiencia, con el objetivo de que sirva como guía para el reconocimiento de niños con condiciones de salud pasibles de CP y la identificación de sus principales problemas y necesidades. Se incluye también un capítulo específico para manejo básico del niño condolor y una guía de abordaje y acompañamiento al niño en fase de agonía y a su familia.

Introducción: la ley 18.335 refiere que: ôToda persona tiene derecho a acceder a una atención integral que comprendaà los cuidados paliativosõ. La Organización Mundial de la Salud (OMS) define los cuidados paliativos pediátricos como ôun modelo global de atención tanto al niño con enfermedad que limita y/o amenaza su vida, como a su familiaõ. El Centro Hospitalario Pereira Rossell cuenta con una unidad de cuidados paliativos pediátricos con fines asistenciales y docentes. Objetivo: describir las características principales de los primeros pacientes asistidos por dicha unidad. Material y método: se realizó un estudio descriptivo, retrospectivo, de las características de los niños asistidos entre el 30 de diciembre de 2008 y el 30 de diciembre de 2010, en base a la revisión de las fichas de registro y las historias clínicas de los pacientes. Se incluyeron todos losniños asistidos, hospitalizados en áreas de cuidados moderados del Departamento de Pediatría. Resultados: se asistieron 87 pacientes, 54 niñas. Mediana de edad: 3 años (rango: 28 días a 16 años). Las condiciones de salud por las que requerían cuidados paliativos fueron muy variadas,predominando los niños con afectación neurológica severa no progresiva. La causa más frecuente de hospitalización fueron las infecciones respiratorias, pero además se constataron otros muy variados problemas biológicos, psicológicos y sociales. Fallecieron 25% de los niños, la mayoría en el hospital.Conclusiones: los cuidados paliativos pediátricos son un derecho de la población. Es por tanto necesario que todos los profesionales de la salud que trabajan con niños se familiaricen con losproblemas presentados y se capaciten en su abordaje integral porque es una obligación del sistema de salud garantizar tal derecho.


Introduction: Law 18,335 provides that: ôAll individuals have the right to receive comprehensive health servicesà including palliative careõ. The World Health Organization (WHO) defined pediatric palliative care as ôa globalmodel for health care services both for the child with a disease that limits and/or threatens his life, and his familyõ. Pereira Rossell Hospital Center has created a Pediatric Palliative Care Unit to provide attention and trainprofessionals in these health care services. Objective: to describe the main characteristics of the first patients seen in the above mentioned unit.Method: We conducted a retrospective, descriptive study of the characteristics of the children seen from December30, 2008 through December 30, 2010, based on their files and medical records. All children hospitalized in the intermediate health care in the Department of Pediatrics were included in the study. Results: 87 patients were seen, 54 of them were girls. Median age was three years old (ranging from 28 days until 16 years old). Health conditions requiring palliative care were varied, mainly non-progressive severe neurological disorders. The most frequent cause of hospitalizationwas respiratory infections, although several other biological, psychological and social problems were seen.25% of the children died, most of them in the hospital. Conclusions: pediatric palliative care is a right. Thus,all health professionals working with children must be familiar with the problems presented and receive training for a comprehensive approach of the condition, since it is an obligation of the health system to guarantee this right.

Material e método: um estudo descritivo, retrospectivo, das características das crianças atendidas no período 30 de dezembro de 2008 - 30 de dezembro de 2010, foi realizado baseado na revisão das fichas de registro e dos expedientes médicos dos pacientes. Todas as crianças atendidas e internadas nas áreas de cuidados moderados do Departamento de Pediatria, foram incluídas. Resultados: 87 crianças foram atendidas, sendo 54 do sexo feminino, com uma mediana de idade de 3 anos (intervalo: 28 dias a 16 anos). As condições de saúde pelasquais necessitavam cuidados paliativos foram muito variadas, predominando crianças com afecções neurológicasseveras não progressivas. A causa mais freqüente de internação foram as infecções respiratórias, mas tambémforam identificados outros problemas biológicos, psicológicos e sociais. Vinte e cinco por cento (25%) das crianças faleceram, a maioria estando internada.Conclusões: os cuidados paliativos pediátricos são um direito da população. Por tanto é necessário que todos os profissionais da saúde que trabalham com crianças estejam familiarizados com os problemas apresentados eestejam capacitados para uma abordagem integral porque é uma obrigação do sistema de saúde assegurar esse direito.

ABSTRACT

Se conoce que la estimulación en el ápex del ventrículo derecho produce disincronía ventricular y muchas veces los pacientes desarrollan miocardiopatía dilatada, lo que ha llevado a realizar una estimulación más fisiológica. Con el reciente desarrollo tecnológico de los electrodos para la estimulación selectiva del haz de His (fisiológica), se quiere mostrar la experiencia en el implante de este tipo de electrodos en los dos primeros casos del servicio de electrofisiología de la Clínica Medellín.


Pacing in the right ventricular apex is known to produce ventricular dysynchrony and patients often develop dilated cardiomiopathy. For this reason, a more physiological stimulation has been performed. With the recent technological development of electrodes for selective stimulation of the His bundle, we want to show the experience of this type of implantation in the first two cases made in the electrophysiology laboratory in Medellin

ABSTRACT

En todos los escenarios de atención pediátrica es creciente el número de niños* asistidos con enfermedades o condiciones de salud que amenazan y/o limitan su vida y la de sus familias. De acuerdo a las definiciones internacionales actuales todos estos niños son pasibles de Cuidados paliativos (CP) y deberían beneficiarse de esta estrategia integral de atención. La presente revisión, es la visión de la Unidad de Cuidados Paliativos Pediátricos del C.H.P.R., basada en la literatura, la experiencia recogida y la reflexión sobre las prácticas. El objetivo es que sea de utilidad para aquellos profesionales que en forma personal o en equipos tengan también interés en mejorar la calidad de asistencia y de vida de estos niños y sus familias. En la misma se presentan herramientas para el razonamiento y abordaje clínico según los siguientes capítulos: I) Identificación de niños pasibles de CP; II) Identificación de problemas biológicos, psicológicos, sociales y de comunicación; III) Identificación y respeto de las necesidades, preferencias y valores del niño y la familia; IV) Equipo de trabajo; V) Comunicación; VI) Toma de decisiones. Garantizar el derecho a los CP, implica desafíos personales en capacitación y desafíos organizativos para el sistema de salud que debemos asumir.

ABSTRACT

Introducción: la fibrilación auricular es el disturbio del ritmo cardiaco sostenido más común. La amiodarona es un antiarrítmico que se usa para la conversión a ritmo sinusal, y la dosis que más se emplea reporta una tasa de éxito de 45% a 85% en las primeras veinticuatro horas; sin embargo, no hay consenso en cuanto a la dosis óptima para el tratamiento de la fibrilación auricular. Objetivo: evaluar la eficacia de amiodarona intravenosa durante las primeras setenta y dos horas en la conversión a ritmo sinusal de pacientes con episodios agudos de fibrilación auricular utilizando una modificación de la dosis recomendada. Métodos: estudio descriptivo-retrospectivo de un grupo de pacientes con episodio agudo de fibrilación auricular durante enero de 2000 a junio de 2006, tratados con la dosis propuesta de amiodarona intra-venosa. Resultado: se evaluaron las historias clínicas de 152 pacientes. La edad promedio fue 61,8 ± 16,9 años; 63,2% de los pacientes era de género masculino. La tasa de conversión a ritmo sinusal fue de 70,5%; de éstos, 81,3% lo hicieron en las primeras veinticuatro horas. La presencia de cardiopatía dilatada y fibrilación auricular permanente, y la respuesta ventricular lenta se asociaron al fracaso de conversión a ritmo sinusal, OR 4,7; 11,5 y 10,2 respectivamente (p < 0,05). Tener corazón sano se asoció con el éxito de conversión a ritmo sinusal, observándose como factor protector (OR 0,28 y p= 0,011). Conclusiones: la dosis de amiodarona propuesta mostró ser eficaz y segura por la baja frecuencia de efectos adversos. Además, resultó costo-efectiva al compararse con otros medicamentos antiarrítmicos disponibles en nuestro medio.


Introduction: atrial fibrillation is the most common sustained cardiac arrhythmia. Amiodarone is an antiarrhythmic used for conversion to sinus rhythm. A success rate of 45 to 85% in the first 24 hours is reported for the most commonly used dose. However, there is no consensus as to the optimal dose for treatment of atrial fibrillation. Objetive: to evaluate the efficacy of IV amiodarone during the first 72 hours for conversion to sinus rhythm in patients with acute episodes of atrial fibrillation using a modification of the recommended dose. Methods: descriptive and retrospective study of all patients presenting with acute atrial fibrillation between January 2000 and June 2006 managed with the proposed dose of IV amiodarone. Results: clinical records of 152 patients were evaluated. Average age was 61.8 ± 16.9 years (SD). 63.2% of patients were male. The rate of conversion to sinus rhythm was 70.5%. Of these, 81.3% converted in the first 24 hours. Presence of dilated cardiomyopathy, occurrence of permanent atrial fibrillation and slow ventricular response were associated with treatment failure, OR 4.73, 11.5 and 10.22 respectively (p<0.05). A structurally healthy heart was associated with successful conversion to sinus rhythm as a protective factor OR 0.28%; p=0.011. Conclusions: the proposed dose of amiodarone was shown to be effective for conversion to sinus rhythm and safe due to the low frequency of adverse side effects encountered. It was also shown to be cost-effective when compared to other antiarrythmic drugs available in our area and with electric cardioversion.

ABSTRACT

La amiloidosis cardiaca es una manifestación de un grupo de enfermedades sistémicas que en conjunto se conocen como amiloidosis. Se considera una causa importante de las enfermedades infiltrativas que pueden ser responsables tanto del compromiso cardiaco como de otros órganos. Dado el avance en el entendimiento de la fisiopatología de la enfermedad, el reconocimiento de sus causas primarias y secundarias, y de las nuevas opciones terapéuticas, se describe un caso típico del compromiso cardiaco y posteriormente se hace una revisión del tema que abarca la mayoría de los tópicos que guardan relación con la amiloidosis primaria con compromiso cardiaco.


Cardiac amyloidosis is a manifestation of a group of systemic diseases, known as amyloidosis. It is considered an important cause of infiltrative diseases that may be responsible for both the heart and other organs’ involvement. Given the progress in the understanding of the pathophysiology of the disease, the recognition of its primary and secondary causes and the new therapeutic options, a typical case of cardiac involvement is described and a review of the subject that covers the great majority of topics related to primary amyloidosis with cardiac involvement is made.

ABSTRACT

En este estudio se describe la frecuencia de fenómenos tromboembólicos sistémicos en el primer trimestre post-operatorio, en pacientes sometidos a reemplazo valvular aórtico por bioprótesis y terapia antitrombótica con ácido acetilsalicílico (de su sigla en inglés ASA).De ochenta pacientes estudiados durante el período 1996 a 2002, solamente 2.5 porciento presentaron tromboembolismo sistémico al sistema nervioso central. No se presentaron casos de muerte y no se observó ninguna complicación hemorrágica por el uso de ASA.En conclusión, el uso de ASA en el primer trimestre post-operatorio de reemplazo valvular aórtico por bioprótesis, parece ser eficaz para prevenir los fenómenos tromboembólicos con mínimo riesgo de sangrado.
