Mitral regurgitation.

Mitral regurgitation (MR) involves systolic retrograde flow from the left ventricle into the left atrium. While trivial MR is frequent in healthy subjects, moderate to severe MR constitutes the second most prevalent valve disease after aortic valve stenosis. Major causes of severe MR in Western countries include degenerative valve disease (myxomatous disease, flail leaflet, annular calcification) and ischaemic heart disease, while rheumatic disease remains a major cause of MR in developing countries. Chronic MR typically progresses insidiously over many years. Once established, however, severe MR portends a poor prognosis. The severity of MR can be assessed by various techniques, Doppler echocardiography being the most widely used. Mitral valve surgery is the only treatment of proven efficacy. It alleviates clinical symptoms and prevents ventricular dilatation and heart failure (or, at least, it attenuates further progression of these abnormalities). Valve repair significantly improves clinical outcomes compared with valve replacement, reducing mortality by approximately 70%. Reverse LV remodelling after valve repair occurs in half of patients with functional MR. Percutaneous, catheter-based to mitral valve repair is a novel approach currently under clinical scrutiny, with encouraging preliminary results. This modality may provide a valuable alternative to mitral valve surgery, especially in critically ill patients.

Grado de pérdida de capacidad laboral asociada a la comorbilidad de los desórdenes músculo esqueléticos en la junta de calificación de invalidez regional Huila, 2009-2012

Resumen: Los desórdenes músculo esqueléticos son entidades que generan un efecto en la salud relacionados con la calidad de vida, dado al impacto global en la condición física, el bienestar psicológico y funcional. Estas entidades generan un gran número de indemnizaciones y en algunas oportunidades según el grado de pérdida de capacidad laboral la invalidez. Objetivo: Determinar la asociación del grado de perdida de la capacidad laboral con la comorbilidad de los desórdenes músculo esqueléticos y otros factores asociados. Materiales y métodos: Se realizó un estudio de corte transversal, basado en registros e historias clínicas. Los registros iniciales fueron 1427 casos, de los cuales 513 presentaban diagnóstico de DME y de estos 240 solicitaron la pérdida de capacidad laboral a la junta de invalidez regional Huila en el periodo comprendido del 2009 al 2012. Resultados: La distribución del grado de la pérdida de capacidad laboral generada de los DME por incapacidad permanente parcial fue del 73,3% y por invalidez el 26,7%. Se encontró una asociación significativa con respecto a la edad (p=0,002), donde el rango de 50-65 años presento mayor pérdida de capacidad laboral; con el género (p=0,047), siendo el femenino más prevalente la invalidez (34,7%) que en el masculino (23,2%) y la comorbilidad (p=0,019), donde los desórdenes músculo esqueléticos y los trastornos depresivos generaron mayor pérdida de capacidad laboral. No se encontró asociación significativa con la escolaridad (p=0,167), oficio (p=0,442) y actividad económica (p=0,118). En el análisis multivariado se encontró asociación significativa con el origen común (OR=4.028, IC 95%: 2.010, 8.072), el sexo femenino (OR=2.565, IC 95%: 1.140, 5.771), y el nivel de escolaridad técnico (OR=12.208, IC 95%: 1.372, 108.634). Conclusiones: La comorbilidad generó mayor pérdida de capacidad laboral, aunque los factores que en conjunto mostraron asociación fueron la edad avanzada, el género femenino, el origen común y el menor nivel educativo.

Evaluación de la validez de la escala llanto para el dolor en neonatos y menores de cinco años

Introducción: La escala LLANTO para dolor es una escala que hasta la fecha ha sido solo validada en población infantil española, actualmente no se conocen datos en población colombiana. Se pretende validar la escala de dolor LLANTO en pacientes neonatos y menores de 5 años, a través de su aplicación en pacientes atendidos en una de tres instituciones, además comparándola con las escalas FLACC y PIPP dependiendo de edad del paciente. Metodología: Se incluyeron niños con cualquier tipo de dolor, clasificándolos en dos grupos por edad: 1) neonatos y 2) niños entre 1 mes y 5 años de edad, que asistieron a la Fundación Cardioinfantil, Clínica Infantil Colsubsidio o al Hospital Universitario Mayor. Las escalas fueron aplicadas por dos residentes de pediatría y una enfermera especializada en el cuidado de población infantil. Para la prueba piloto se diseñó un cuestionario determinar dificultades en la aplicación de la escala LLANTO. Una vez corregidos los problemas identificados se procederá a la validación de la escala. Resultados: Se presentan los datos de la prueba piloto. Se incluyeron 8 neonatos y 8 niños entre 1 mes y 5 años, esta muestra fue obtenida en un periodo de un mes, con la encuesta se evaluó la aceptación y entendimiento de la escala LLANTO por parte de los evaluadores. La prueba piloto mostró resultados favorables en el 100% de los encuestados. Discusión: Se considera que la escala LLANTO no requiere cambios para continuar con su validación.

Factores asociados a mortalidad en pacientes colombianos con enfermedades autoinmunes en la unidad de cuidado intensivo, de un hospital de tercer nivel en Bogotá Colombia

Antecedentes: El interés en las enfermedades autoinmunes (EA) y su desenlace en la unidad de cuidado intensivo (UCI) han incrementado debido al reto clínico que suponen para el diagnóstico y manejo, debido a que la mortalidad en UCI fluctúa entre el 17 – 55 %. El siguiente trabajo representa la experiencia de un año de nuestro grupo en un hospital de tercer nivel. Objetivo: Identificar factores asociados a mortalidad particulares de los pacientes con enfermedades autoinmunes que ingresan a una UCI, de un hospital de tercer nivel en Bogotá, Colombia. Métodos: El uso de análisis de componentes principales basado en el método descriptivo multivariado y análisis de múltiple correspondencia fue realizado para agrupar varias variables relacionadas con asociación significativa y contexto clínico común. Resultados: Cincuenta pacientes adultos con EA con una edad promedio de 46,7 ± 17,55 años fueron evaluados. Los dos diagnósticos más comunes fueron lupus eritematoso sistémico y esclerosis sistémica, con una frecuencia de 45% y 20% de los pacientes respectivamente. La principal causa de admisión en la UCI fue la infección seguido de actividad aguda de la EA, 36% y 24% respectivamente. La mortalidad durante la estancia en UCI fue del 24%. El tiempo de hospitalización antes de la admisión a la UCI, el choque, soporte vasopresor, ventilación mecánica, sepsis abdominal, Glasgow bajo y plasmaféresis fueron factores asociados con mortalidad. Dos fenotipos de variables fueron definidos relacionadas con tiempo en la UCI y medidas de soporte en UCI, las cuales fueron asociadas supervivencia y mortalidad. Conclusiones: La identificación de factores individuales y grupos de factores por medio del análisis de componentes principales permitirá la implementación de medidas terapéutica de manera temprana y agresiva en pacientes con EA en la UCI para evitar desenlaces fatales.

Caracterización epidemiológica de la artritis idiopática juvenil y refractariedad a dmard en una institución en Bogotá

La artritis idiopática juvenil (AIJ) es la enfermedad reumatológica crónica más común de la infancia con repercusiones importantes en la calidad de vida del paciente y su familia; las alteraciones físicas presentadas pueden ocasionar ausentismo escolar. Los tratamientos de uso crónico utilizados hacen que la adherencia al mismo en la población infantil y adolescente sea todo un reto. A esto se adiciona la refractariedad a DMARDs (Disease – Modifying – Antirheumatic – Drugs) que conlleva al inicio de terapia biológica y a cambios en el pronóstico de la enfermedad. Materiales y métodos: Estudio observacional retrospectivo mediante la revisión de las historias clínicas de pacientes con diagnóstico de artritis idiopática juvenil que consultaron a la Fundación Cardioinfantil desde enero del 2008 a septiembre de 2015. Se obtuvieron datos como edad, sexo, edad de diagnóstico, manejo actual, remisión, seguimiento, tratamiento, cambios realizados en el mismo y refractariedad a DMARD. Resultados: De 108 registros clínicos evaluados, 90 cumplieron los criterios de elegibilidad. Se diagnosticó con mayor frecuencia en el sexo femenino con un 57.8%, media de edad de 7.88 años. El subtipo poliarticular con Factor Reumatoideo negativo se presentó con una frecuencia con 31,1 %. El tiempo transcurrido entre el inicio de la sintomatología en meses, previo a realizar el diagnóstico, osciló entre 1 y 60 meses con una media de 10,6 meses. Se usaron con mayor frecuencia: AINES (61,1%), metotrexate (47,8%) y corticoides (42,2%). De los 90 pacientes, solo un 11.1% de la población presentó complicaciones, siendo la más frecuente la obesidad en un 3,3 % y la menos frecuente la uveítis con un 1,1%. Discusión: Es importante el entendimiento de la Artritis idiopática juvenil como una entidad de carácter sistémica, lo cual hace necesario el conocimiento de la epidemiología para establecer estrategias de manejo y seguimiento adecuadas. El género femenino continúa siendo afectado en mayor porcentaje. Se observaron leves cambios respecto al subtipo de mayor frecuencia comparado con estudios previos. Se necesitan más estudios de caracterización epidemiológica en la población Colombiana para realización de políticas de salud pública

Consenso de imunização para crianças e adolescentes com doenças reumatológicas

Crianças e adolescentes com doenças reumatológicas apresentam maior prevalência de doenças infecciosas quando comparados com a população em geral, em decorrência de atividade da doença, possível deficiência imunológica secundária à própria doença, ou uso de terapia imunossupressora. A vacinação é uma medida eficaz para a redução da morbidade e mortalidade nesses pacientes. O objetivo deste artigo foi realizar um consenso de eficácia e segurança das vacinas em crianças e adolescentes com doenças reumatológicas infantis baseadas em níveis de evidência científica. Imunização passiva para os pacientes e orientações para as pessoas que convivem com doentes imunodeprimidos também foram incluídas. Os 32 pediatras reumatologistas membros do Departamento de Reumatologia da Sociedade de Pediatria de São Paulo (SPSP) e/ou da Comissão de Reumatologia Pediátrica da Sociedade Brasileira de Reumatologia elaboraram o consenso, sendo que alguns desses profissionais estão envolvidos em pesquisas e publicações científicas nesta área. A pesquisa dos termos eficácia e/ou segurança das diferentes vacinas em crianças e adolescentes com doenças reumatológicas foi realizada nas bases de Medline e Scielo, de 1966 até março de 2009, incluindo revisões, estudos controlados e relatos de casos. O grau de recomendação e o nível científico de evidências dos estudos foram classificados em quatro níveis para cada vacina. de um modo geral, as vacinas inativadas e de componentes são seguras nos pacientes com doenças reumatológicas, mesmo em uso de terapias imunossupressoras. Entretanto, vacinas com agentes vivos atenuados são, em geral, contraindicadas para os pacientes imunossuprimidos.

Prática de vacinação em crianças com doenças reumáticas

INTRODUÇÃO/OBJETIVOS: Avaliar a prática clínica com relação à verificação do cartão vacinal e à indicação de vacinas específicas em pacientes com doenças reumáticas pediátricas em uso de diferentes drogas, e evidenciar a possível associação entre frequência de vacinação e tempo de prática clínica dos reumatologistas pediátricos do estado de São Paulo. MATERIAL E MÉTODOS: Um questionário foi enviado para os reumatologistas pediátricos do Departamento de Reumatologia da Sociedade de Pediatra de São Paulo. Esse instrumento incluiu questões sobre tempo de prática em Reumatologia Pediátrica, vacinação de pacientes com Lúpus Eritematoso Sistêmico Juvenil (LESJ), artrite idiopática juvenil (AIJ), dermatomiosite juvenil (DMJ) e imunização de acordo com os tratamentos utilizados. RESULTADOS: Cartão de vacinação foi visto por 100% dos profissionais na primeira consulta e por 36% anualmente. Vacinas de agentes vivos não foram recomendadas para pacientes com LESJ, AIJ e DMJ em 44%, 64% e 48%, respectivamente. Os profissionais foram divididos em dois grupos: A (< 15 anos de prática, n = 12) e B (> 16 anos, n = 13). Nenhuma diferença estatística foi observada no uso de vacinas de agentes vivos e vacinas de agentes inativos ou componentes proteicos em relação ao tratamento nos dois grupos (P > 0,05). Além disso, os grupos foram similares em relação à opinião sobre a gravidade de imunossupressão em pacientes com LESJ, AIJ e DMJ com ou sem atividade e a terapêutica utilizada (P > 0,05). CONCLUSÕES: A frequência de vacinação por reumatologistas pediátricos de São Paulo é baixa, especialmente após a primeira consulta, e não é influenciada pelo tempo de prática profissional.

Abuso sexual, transtornos mentais e doencas fisicas

Objective: to review and describe the different organic and psychic consequences of sexual abuse. Methodology: 71 papers were sorted in a ten-year literature search (1987-1997) in MedLine and Lilacs (South American Literature Index), besides 14 books in the subject. Results: sexual abuse is much less frequent (or less reported) in Brazil: 7% of the population, while in the USA the prevalence is 12.9% to 28% of women and 2% to 9% of men. Results showed women being more frequently sexually abused but less differences in physical abuse were found between genders. There was a significant association between sexual abuse and the following: eating disorders, depression, irritable bowel, chronic pain (mainly pelvic), neurological, rheumatic and venereal disorders. This association was not observed in chronic constipation, Chron disease and dissociative disorders. Conclusions: although it is important to think of sexual/physical abuse as a predisposing factor to several illnesses, caution is necessary specially in cultures with different moral and ethical values. Research in this subject in Brazil should be conducted with patients in treatment, using control groups, in order to take advantage of the existing rapport. It would be also quite important to separate acute and chronic abuse effects, as well as getting to know the meaning of the experienced abuse to each person.

Composição do óleo essencial de rubim (Leonurus sibiricus L. - Lamiaceae)

The essential oils are found in a great number of Lamiaceae family species, but few researches were carried out on this subject. This work had as a goal to identify the Leonurus sibiricus L. (rubim) essential oil composition. Rubim leaves and flowers in infusion are able to avoid vomit, diarrhea, and are also indicated in cold, cough, bronchitis and rheumatisms cases. In order to know what are the phytochemical compositions involved, it was used the gas chromatography techniques with mass spectrometry (GC-MS) as methodology. The results showed 70% volatility compound by trans-cariophylene, alpha-humulene and germacrene-D. Other substances like gamacadinene, beta-bourborene and alpha-copaene were found like compounds of this essential oil species.

Juvenile localized scleroderma: Clinical and epidemiological features in 750 children. An international study

Objective. Juvenile localized scleroderma (JLS) includes a number of conditions often grouped together. With the long-term goal of developing uniform classification criteria, we studied the epidemiological, clinical and immunological features of children with JLS followed by paediatric rheumatology and dermatology centres. Methods. A large, multicentre, multinational study was conducted by collecting information on the demographics, family history, triggering environmental factors, clinical and laboratory features, and treatment of patients with JLS. Results. Seven hundred and fifty patients with JLS from 70 centres were enrolled into the study. The disease duration at diagnosis was 18 months. Linear scleroderma (LS) was the most frequent subtype (65%), followed by plaque morphea (PM) (26%), generalized morphea (GM) (7%) and deep morphea (DM) (2%). As many as 15% of patients had a mixed subtype. Ninety-one patients (12%) had a positive family history for rheumatic or autoimmune diseases; 100 (13.3%) reported environmental events as possible trigger. ANA was positive in 42.3% of the patients, with a higher prevalence in the LS-DM subtype than in the PM-GM subtype. Scl70 was detected in the sera of 3% of the patients, anticentromere antibody in 2%, anti-double-stranded DNA in 4%, anti-cardiolipin antibody in 13% and rheumatoid factor in 16%. Methotrexate was the drug most frequently used, especially during the last 5 yr. Conclusion. This study represents the largest collection of patients with JLS ever reported. The insidious onset of the disease, the delay in diagnosis, the recognition of mixed subtype and the better definition of the other subtypes should influence our efforts in educating trainees and practitioners and help in developing a comprehensive classification system for this syndrome. © 2006 Oxford University Press.

Risk-assessment algorithm and recommendations for venous thromboembolism prophylaxis in medical patients

The risk for venous thromboembolism (VTE) in medical patients is high, but risk assessment is rarely performed because there is not yet a good method to identify candidates for prophylaxis. Purpose: To perform a systematic review about VTE risk factors (RFs) in hospitalized medical patients and generate recommendations (RECs) for prophylaxis that can be implemented into practice. Data sources: A multidisciplinary group of experts from 12 Brazilian Medical Societies searched MEDLINE, Cochrane, and LILACS. Study selection: Two experts independently classified the evidence for each RF by its scientific quality in a standardized manner. A risk-assessment algorithm was created based on the results of the review. Data synthesis: Several VTE RFs have enough evidence to support RECs for prophylaxis in hospitalized medical patients (eg, increasing age, heart failure, and stroke). Other factors are considered adjuncts of risk (eg, varices, obesity, and infections). According to the algorithm, hospitalized medical patients ≥40 years-old with decreased mobility, and ≥1 RFs should receive chemoprophylaxis with heparin, provided they don't have contraindications. High prophylactic doses of unfractionated heparin or low-molecular-weight-heparin must be administered and maintained for 6-14 days. Conclusions: A multidisciplinary group generated evidence-based RECs and an easy-to-use algorithm to facilitate VTE prophylaxis in medical patients. © 2007 Rocha et al, publisher and licensee Dove Medical Press Ltd.

Intervention to reduce C-reactive protein determination requests for acute infections at an emergency department

Introduction C-reactive protein (CRP) levels rise during inflammatory processes and have been ordered for rheumatic disease follow-up since the 1950s. The number of tests ordered in the emergency setting has increased, but without evident improvement in medical care quality. Objective To determine the pattern of CRP determinations in the emergency department (ED) of a university hospital in Sao Paulo, Brazil, and to evaluate the effect of an intervention with staff and students about the best use of the test in the ED. Methods Data regarding CRP testing requests, related diagnoses and the number of monthly consultations in the hospital ED were analysed before and after the intervention. Because of an increase in CRP measurement requests from 2007 to 2009, the author started discussing the role of CRP determinations in the medical decision-making process in early 2010. Staff and faculty members openly discussed the pattern of requests in the hospital and related current medical literature. During 2010, the medical staff worked as multipliers to change the behaviour of new students and residents. The results of the first 4 months after the intervention were presented at another general meeting in July 2010. Results From 2007 to 2009, there were 11 786 CRP measurement requests with a clear exponential trend. After the intervention, during the calendar year 2010, there was a 48% reduction in adjusted annual CRP requests. Pneumonia, fever and urinary tract infections were the most common reasons for CRP requests. Discussion Inexpensive, well-directed, interactive educational interventions may affect professional behaviour and curb rates of laboratory tests.

TNF blockers show distinct patterns of immune response to the pandemic influenza A H1N1 vaccine in inflammatory arthritis patients

Methods. One hundred and twenty patients (RA, n = 41; AS, n = 57; PsA, n = 22) on anti-TNF agents (monoclonal, n = 94; soluble receptor, n = 26) were compared with 116 inflammatory arthritis patients under DMARDs and 117 healthy controls. Seroprotection, seroconversion (SC), geometric mean titre, factor increase in geometric mean titre and adverse events were evaluated 21 days after vaccination. Results. After immunization, SC rates (58.2% vs 74.3%, P = 0.017) were significantly lower in SpA patients receiving anti-TNF therapy, whereas no difference was observed in RA patients receiving this therapy compared with healthy controls (P = 0.067). SpA patients receiving mAbs (infliximab/adalimumab) had a significantly lower SC rate compared with healthy controls (51.6% vs 74.3%, P = 0.002) or those on DMARDs (51.6% vs 74.7%, P = 0.005), whereas no difference was observed for patients on etanercept (86.7% vs 74.3%, P = 0.091). Further analysis of non-seroconverting and seroconverting SpA patients revealed that the former group had a higher mean age (P = 0.003), a higher frequency of anti-TNF (P = 0.031) and mAbs (P = 0.001) and a lower frequency of MTX (P = 0.028). In multivariate logistic regression, only older age (P = 0.015) and mAb treatment (P = 0.023) remained significant factors for non-SC in SpA patients. Conclusion. This study revealed a distinct disease pattern of immune response to the pandemic influenza vaccine in inflammatory arthritis patients receiving anti-TNF agents, illustrated by a reduced immunogenicity solely in SpA patients using mAbs.
