Environmental exposure to pesticides and Amyotrophic Lateral Sclerosis in the South of Spain.

OBJECTIVE: To determine if there is a relationship between environmental exposure to pesticides and the prevalence of Amyotrophic Lateral Sclerosis (ALS) in Andalusia. METHOD: We carried out a case-control study using the logistic regression method to verify the relationship between the prevalence of ALS in the area exposed to pesticides versus the unexposed area, through the Odds Ratio statistical test. RESULTS: The study population consisted of 519 individuals diagnosed with ALS between January 2016 and December 2018 according to the CMBD (Minimum Basic Data Set) as cases. In the control group, we have 8,384,083 individuals obtained from data from the National Institute of Statistics (INE). The Odds Ratio (OR) was used as a measure of association between cases and controls, obtaining an OR between 0.76 and 1.08 for the confidence interval of the CI (95%). CONCLUSIONS: Despite the existence of various studies that suggest a possible association between environmental exposure to pesticides and the risk of Amyotrophic Lateral Sclerosis, our analysis of the Andalusian population did not find significant evidence of this association.

Objetivo: Analizar si existe una relación entre la exposición ambiental a pesticidas y la prevalencia de esclerosis lateral amiotrófica (ELA) en Andalucía. Métodos: Realizamos un estudio de casos y controles con regresión logística para esclarecer la relación entre la prevalencia de ELA en el área expuesta a pesticidas vs. el área sin exposición, mediante el cálculo de razón de probabilidades (odds ratio [OR]). Resultados: Incluimos un grupo de casos, con 519 individuos diagnosticados de ELA entre enero de 2016 y diciembre de 2018, obtenidos del conjunto mínimo básico de datos, y un grupo control con 8.384.083 individuos obtenidos de la base de datos del Instituto Nacional de Estadística. Se utilizó la OR para medir la asociación entre casos y controles, con un intervalo de confianza del 95% de 0,76-1,08. Conclusiones: A pesar de que varios estudios sugieren una posible asociación entre la exposición ambiental a pesticidas y un aumento en el riesgo de ELA, nuestro estudio sobre la población andaluza no halló datos significativos en favor de dicha hipótesis.(AU)

Documento de posicionamiento sobre la incorporación de la ecografía clínica en los servicios de Medicina Interna / Positioning document on incorporating point-of-care ultrasound in Internal Medicine departments

Este documento de posicionamiento describe los aspectos más importantes de la ecografía clínica en el ámbito de la Medicina Interna, desde sus indicaciones fundamentales hasta el período de formación recomendado. Actualmente ya no quedan dudas sobre la gran utilidad de esta herramienta para la práctica clínica habitual del internista en múltiples escenarios clínicos y ámbitos de actuación (urgencias, planta de hospitalización, consulta general y específica y atención domiciliaria). Su uso tiene un impacto relevante en la capacidad de resolución del profesional, al aumentar su fiabilidad y seguridad diagnóstica, además de proporcionar información pronóstica y evolutiva importante. Además, en los últimos años se ha incorporado como una herramienta en la enseñanza pregrado con excelentes resultados. Por tanto, es necesario generalizar su uso y para ello se debe fomentar la formación estructurada y la adquisición de equipos. El documento ha sido elaborado por el Grupo de Trabajo de Ecografía Clínica y avalado por la Sociedad Española de Medicina Interna

This positioning document describes the most important aspects of clinical ultrasonography in the internal medicine setting, from its fundamental indications to the recommended training period. There is no question as to the considerable usefulness of this tool in the standard clinical practice of internists in numerous clinical scenarios and settings (emergencies, hospital ward, general and specific consultations and home care). Ultrasonography has a relevant impact on the practitioner's ability to resolve issues, increasing diagnostic reliability and safety and providing important information on the prognosis and progression. In recent years, ultrasonography has been incorporated as a tool in undergraduate teaching, with excellent results. The use of ultrasonography needs to be widespread. To accomplish this, we must encourage structured training and the acquisition of equipment.

Utilidad diagnóstica de la ecografía de bolsillo en la insuficiencia cardiaca / Diagnostic utility of handheld ultrasonography as an extension of the physical examination of patients with heart failure

Antecedentes y objetivos: La ecocardiografía convencional es la técnica de elección para valorar la función del ventrículo izquierdo y la presencia de cardiopatía estructural en pacientes con insuficiencia cardiaca. El objetivo del estudio ha sido valorar el rendimiento diagnóstico de la ecografía de bolsillo realizada por un médico internista en pacientes con diagnóstico clínico de insuficiencia cardiaca. Pacientes y métodos: Estudio observacional transversal de 212 pacientes con diagnóstico de insuficiencia cardiaca en un centro hospitalario. Un médico internista con formación básica en ecocardiografía realizó una exploración mediante ecografía de bolsillo y valoró, de forma semicuantitativa, diferentes variables. Se valoraron la función sistólica del ventrículo izquierdo, dimensión de cavidades, valvulopatías significativas, derrame pericárdico y el diámetro de la vena cava inferior. Resultados: La exploración mediante ecografía de bolsillo se realizó en menos de 6min. La concordancia entre los diagnósticos del médico internista y el ecocardiografista experto fue muy buena (k>0,81) para el diámetro, hipertrofia y función sistólica del ventrículo izquierdo, regurgitación valvular, derrame pericárdico y el diámetro de la vena cava inferior. Conclusiones: La ecocardiografía de bolsillo realizada por un médico internista, como extensión de la exploración física en pacientes con insuficiencia cardiaca, es una prueba válida y segura y permite incrementar el rendimiento diagnóstico de la historia clínica (AU)

Background and objectives: Conventional echocardiography is the technique of choice for assessing left ventricular function and the presence of structural heart disease in patients with heart failure. The aim of this study was to assess the diagnostic performance of handheld ultrasonography performed by a medical internist on patients with a clinical diagnosis of heart failure. Patients and methods: Cross-sectional observational study of 212 patients diagnosed with heart failure in a hospital center. A medical internist with basic training in echocardiography performed an examination using handheld ultrasonography and semiquantitatively assessed several variables. The patients’ left ventricular systolic function was assessed, along with the cavity dimensions, significant valvular heart disease, pericardial effusion and the diameter of the inferior vena cava. Results: The examination using handheld ultrasonography was conducted in less than 6minutes. The agreement between the diagnoses of the medical internist and the expert echocardiographist was very good (k>0.81) for the diameter, hypertrophy and left ventricular systolic function, valvular regurgitation, pericardial effusion and diameter of the inferior vena cava. Conclusions: Handheld echocardiography performed by a medical internist, as an extension of the physical examination of patients with heart failure, is a valid and safe test that helps increase the diagnostic performance (AU)

La investigación biomédica, el mercado, los clínicos, la seguridad y la responsabilidad social corporativa posfase III: retener la confianza / Biomedical research, the market, clinicians, safety and corporate social responsibility post-phase III: maintaining confidence

Introducción: Los ensayos controlados aleatorios son el gold standar occidental respecto a la toma de decisiones, tanto para los clínicos como para los gestores o responsables de políticas comunitarias. En este poderoso despliegue de esfuerzo investigador existen grados variables de conflictos de intereses y los clínicos, que no somos ajenos a eso, estamos entrando en un mar de dudas acerca de la seguridad, dimensión que emerge como un elemento diacrítico, irrenunciable. El objeto del estudio fue toda evaluación crítica y la selección sobre editoriales, ensayos clínicos o metaanálisis publicados en soporte físico o vía web, acreditados internacionalmente, que resultaran más relevantes y que abordaran como objetivo primario la seguridad de los pacientes. Pacientes y métodos: Investigación evaluativa que se llevó a cabo en el Complejo Hospitalario Torrecárdenas, perteneciente al Servicio Andaluz de Salud. Sistema Sanitario Público de Andalucía, en el contexto de una unidad formativa acreditada (Mejora_F) en 2008, denominada «transferencia del conocimiento biomédico desde la bibliografía». Resultados: Los artículos analizados fueron 170 (el 75% en inglés, con predominio de New England Journal of Medicine [>50%], seguida de Journal Of the American Medical Association, The Lancet, British Medical Journal, Journal of American Geriatrics, Medicina Clínica, Revista Clínica Española e Infectología). De los 170 artículos elegibles, seleccionamos 5 tópicos clave por su impacto como los más representativos por su frecuencia de citación. Representaron, a nuestro juicio, «una bandera roja» de seguridad los siguientes: betaestimulantes de acción larga y aumento de mortalidad en asma; neurolépticos en ancianos y prolongación del intervalo QT asociado a muerte súbita; tiazolidindiona en diabetes de tipo ii y efectos negativos cardiovasculares; potenciación de estatinas-ezetimiba y discutible asociación con mayor mortalidad por cáncer, y tratamiento intensivo en diabetes y probable aumento de mortalidad. Conclusiones: Lo que realmente importa en biomedicina es qué efectos provoca una estrategia dada en los pacientes reales, no en los puntos intermedios. Los clínicos no deberíamos apoyar resultados parciales de diseños basados en datos intermedios -indudablemente menos costosos y más rápidos- sin conocer adecuadamente la seguridad de la estrategia erigida para alcanzarlos. Sólo así nos constituimos en verdaderos garantes de la seguridad, sólo así, y en ausencia de conflictos de intereses, podremos mantener la confianza dada (AU)

Introduction: Randomised controlled trials (RCTs) are the gold standard in the western world for decision making, as much for the clinicians as for the agencies or managers for community policies. In this powerful deployment of investigative effort there are variable degrees of conflict of interests, and the clinicians, not foreign to this, are entering a sea of doubts on safety, a dimension that emerges like a diacritical, inalienable element. The aim of the study was to select and ctically evaluate editorials, clinical trials and/or meta-analyses published on physical support, or the more important internationally credited websites, which has patient safety as their primary objective. Patients and Methods: Evaluative study performed in the Torrecardenas Hospital, of the Andalucian Public Health Service (SSPA), in the context of an accredited training unit (Mejora_F), so called "transference of the biomedical knowledge from the bibliography" from 2008 to 2009. Results: Analyzed articles: 170 (75 % in English, with predominance of N Eng J Med >50 %; followed by Journal Of the American Medical Association, The Lancet, British Medical Journal, Journal of American Geriatrics; Med Clin, Rev Clin Esp.; and Infectología). From 170 eligible articles we selected 5 key topoi due to their impact as the most representative owing to their citation frequency. They represented, in our judgment, "a red flag" of safety: long-acting beta-stimulators or LABS and increase in mortality in asthma; neuroleptics in the elderly and extension of the QT interval associated with sudden death; thiazolidinediones in type II diabetes and negative cardiovascular effects; promotion of statins-ezetimibe and the debatable association with major mortality for cancer, and intensive treatment in diabetes and probable increase in mortality. Conclusions: What really maters in biomedicine is that it leads to a given strategy in real patients, not the intermediate points. Clinicians should not support partial results of designs based on intermediate information -undoubtedly less costly and more rapid- without adequately knowing the safety of the strategy built to reach them. Only in this way we can be real guarantors of safety, and only in this way, and in absence of conflicts of interests we will be able to support the given confidence (AU)

Rose Bengal test: diagnostic yield and use for the rapid diagnosis of human brucellosis in emergency departments in endemic areas.

The aim of the present study was to analyse the diagnostic yield of the rose Bengal test for the rapid diagnosis of human brucellosis in an emergency department in an area where the disease is endemic. The study included 711 patients diagnosed initially with brucellosis and 270 controls. Brucellosis patients were divided into three groups: group I, individuals with no regular exposure to or history of brucellosis; group II, individuals exposed repeatedly to Brucella infection; and group III, individuals infected with Brucella who had received appropriate treatment during the previous 12 months. Blood cultures were positive for 445 (62.6%) brucellosis patients, while the remaining 266 (37.4%) patients were diagnosed according to clinical and serological criteria. The overall sensitivity of the rose Bengal test was 92.9%. The specificities for groups I, II and III were 94.3%, 91.7% and 76.9%, respectively, with positive likelihood ratios of 16.5, 10.4 and 4.2, respectively. The diagnostic gain after the performance of the rose Bengal test was good or very good in patients with no previous exposure to Brucella or history of brucellosis, but poor in patients who were exposed repeatedly to Brucella or had a history of brucellosis and a low pre-test probability. Use of the rose Bengal test as the sole technique for the diagnosis of brucellosis in endemic areas should be considered very carefully in the context of patients who are exposed repeatedly to Brucella or have a history of brucellosis.

[Anticoagulation with bemiparina after intracerebral hemorrhage as complication of bacterial endocarditis on metallic prosthetic valve]. / Anticoagulación con bemiparina tras hemorragia intracerebral como complicación de endocarditis bacteriana sobre válvula protésica metálica.

We present the case of a patient with an intracerebral hemorrhage as complication of an infectious endocarditis (EI) produced by Neisseria sicca on a prosthetic mitral valve. The patient was anticoagulated previously with Acenocumarol as prophylaxis of thrombosis of the prosthetic valve. He was diagnosed as having IE and later he presented neurological symptoms as consequence of several intracerebral hemorrhagic foci. We decided to continue the anticoagulation with sodium heparin followed of Bemiparina and no new hemorrhagic complications nor thrombosis of the valve were observed after three months of the event. We have not found in the literature any case where low molecular weight heparin has been used as method of anticoagulation in these cases beyond two weeks.

Presentamos el caso de un paciente con una hemorragia intracerebral como complicación de una endocarditis infecciosa (EI) producida por Neisseria sicca sobre una válvula mitral metálica. El paciente estaba previamente anticoagulado con Acenocumarol como profilaxis de trombosis de la válvula protésica. Fue diagnosticado de EI y posteriormente presentó síntomas neurológicos como consecuencia de varios focos hemorrágicos intracerebrales. Se decidió continuar la anticoagulación con heparina sódica inicialmente y posteriormente con Bemiparina, no observándose nuevas complicaciones hemorrágicas ni trombosis de la válvula a los tres meses del evento. No hemos encontrado en la literatura ningún caso donde la heparina de bajo peso molecular (HBPM) haya sido utilizada como método de anticoagulación en estos casos más allá de dos semanas (AU)
