ABSTRACT

Resumen Introducción: El ángulo QRS-T espacial es la diferencia entre el vector del QRS y la T. Se conoce el valor diagnóstico y pronóstico de este marcador en enfermedades cardíacas. Es prioritario determinar si estas mediciones son reproducibles con confiabilidad en nuestro medio. Métodos: En 30 adultos se obtuvieron electrocardiogramas, independientemente del diagnóstico. Las mediciones las realizaron dos estudiantes de Medicina de quinto año, un médico interno y un cardiólogo, posterior a un reentrenamiento sobre la medición del ángulo por el método de transformación visual. Con identificación cegada, ingresaron en un aplicativo web las mediciones del QRS y la T. El ángulo fue estimado a partir de la plantilla de Cortez y colaboradores. Sobre el 20% de las lecturas se estimó un acuerdo intraobservador y en el 100% de las lecturas un acuerdo interobservador. Los puntos de corte para estimar el acuerdo Kappa fueron < 105s (normal), 105° a 135° (limítrofe) y > 135° (anormal). Resultados: Se excluyó un ECG por calidad deficiente. El rango del ángulo estuvo entre 72.9° y 176.2°. El acuerdo interobservador entre los 4 evaluadores fue kappa = 0.786 (IC95% 0.728-0.823, p < 0.0001) y el intraobservador kappa = 1.0 (p 0.007). Conclusión: Es el primer estudio sobre el ángulo QRS-T espacial realizado en Colombia. Se logró un acuerdo inter- e intraobservador adecuado en la medición del ángulo por el método de transformación visual, en observadores con diferente experticia, con un kappa mayor de 0,75. Este resultado apoya la reproducibilidad de esta medición en estudios posteriores en Colombia.


Abstract Introduction: The spatial QRS-T angle is the difference between the QRS vector and T vector. The diagnostic and prognostic value of this marker in heart disease is well-known. It is essential to determine whether these measurements are reproducible and reliable in Colombia. Methods: Electrocardiograms (ECG) were obtained from 30 adults, regardless of the diagnosis. The measurements were made by two fifth-year medical students, a houseman/ intern, and a cardiologist. They were all re-trained on the measurement of the angle using the visual transformation method. With blinded identification, they entered the QRS and T measurements into a web application. The angle was estimated from the template of Cortez et al. About 20% of the readers showed an intra-observer agreement and an inter-observer agreement in 100%. The cut-off points to estimate the agreement Kappa were < 105° (normal), 105° a 135° (borderline), and >135° (abnormal). Results: One ECG was excluded due to poor quality. The range of the angle was between 72.9° and 176.2°. The inter-observer agreement between the 4 evaluators gave a kappa = 0.786 (95% CI; 0.728-0.823, P < .0001), and the intra-observer agreement a kappa = 1.0 (P = .007). Conclusion: This the first study on the spatial QRS-T angle performed in Colombia. A good inter- and intra-observer agreement was achieved in the measurement of the angle by the visual transformation method by observers with different levels of expertise, with a Kappa greater than 0.75. These results support the reproducibility of this measurement in subsequent studies in Colombia.

ABSTRACT

High blood pressure (BP) is the leading global preventable cause of death and the most common risk factor for cardiovascular disease (CVD). However, due to its asymptomatic nature, the lack of awareness of this condition causes underdiagnosis and low rates of adherence to pharmacological treatment. Looking for practical approaches to increase awareness worldwide, the International Society of Hypertension (ISH) implemented the 2nd May Measurement Month campaign in 2018 (MMM18). In order to contribute to this initiative, Colombia participated as one of the 89 countries involved in this hypertension screening programme. Blood pressure was measured in subjects from 11 departments in Colombia. Under the leadership of the Fundación Oftalmológica de Santander (FOSCAL), 400 volunteers across the country collected the data following the MMM protocol. Measurements from 35 548 participants with a mean age of 41.9 years were obtained. In total, 9475 (26.7%) of the total population studied had hypertension. Of those with hypertension, 69.9% of these subjects were aware of their condition, 65.0% were on antihypertensive medication, and 43.1% had controlled BP. Of those on medication, 66.3% had controlled BP. Hypertension screening, awareness, treatment, and control should be a priority in public health objectives due to its elevated burden of disease and direct association with increased CVD. The MMM campaign provided a positive impact in the diagnosis of hypertension across Colombia. Although efforts are being made to expand treatment capability and adherence, still more are needed to insure a broader coverage of antihypertensive medication in Colombia.

ABSTRACT

El sÝndrome de inmunodeficiencia adquirida es una enfermedad de alta mortalidad causada por el virus de la inmunodeficiencia humana (VIH), el cual se caracteriza por un defecto adquirido aparentemente irreversible en la inmunidad celular, que predispone al huÚsped a infecciones oportunistas severas y/o neoplasias inusuales. Se estima que el VIH infecta a 1000 niños cada dÝa en el mundo, el 90 por ciento se han contaminado durante el embarazo, parto o lactancia, a partir de una madre infectada. La infección perinatal por el VIH deberÝa ser considerada como una enfermedad familiar que requiere el manejo mÚdico multidisciplinario y servicios de atención social. En este trabajo presentamos el caso de un paciente de 3 años de edad infectado por el VIH, cuyos padres tambiÚn estaban infectados. Este niño presentaba una problemßtica bucal de caries rampante. Vale la pena destacar que Úste es el primer caso VIH(+) de nuestro postgrado, el cual se trata bajo anestesia general y fue atendido por un equipo multidisciplinario conformado por mÚdicos, odontólogos y un auxiliar de la Facultad de OdontologÝa de la U.C.V. y de los hospitales J. M. de los RÝos y Universitario de Caracas
