Síndromes de la onda J J wave syndromes
Annerys Méndez Rosabal
Revista Cubana de Investigaciones Biom??dicas , 2012,
Abstract: Se realizó una revisión sobre los aspectos más novedosos y polémicos de los síndromes de la onda J, que incluyó el síndrome de repolarización precoz, la fibrilación ventricular idiopática y la muerte súbita nocturna inexplicable. Se enfatiza en las características electrocardiográficas de estos síndromes donde se destaca la presencia de un supradesnivel del ST tipo cóncavo con melladuras o empastamiento del mismo. Se profundiza en las bases genéticas, a veces común a todos ellos, en particular la mutación SCN5A asociada con el supradesnivel del ST y más recientemente la mutación S422L-KCNJ8 como causa de alteración de los canales I K-ATP, lo cual se asocia con mortalidad arrítmica cardíaca. Se concluye que aunque no todos los pacientes con este síndrome estén en riesgo de eventos arrítmicos o de muerte súbita cardíaca, existe un grupo de ellos no despreciable que sí lo están, por lo que el gran desafío de la comunidad médica es desarrollar mejores estrategias de estratificación de riesgo y desarrollar tratamientos más seguros y eficaces para estos. A review was conducted of the newest and most controversial aspects of J wave syndromes, including early repolarization syndrome, idiopathic ventricular fibrillation and sudden unexplained nocturnal death. Emphasis is made on the ECG features of these syndromes, among them the presence of an upwardly concave ST irregularity with notching or slurring. A detailed analysis is made of genetic bases, which are sometimes common to all syndromes, particularly the SCN5A mutation, associated with the ST upwardly irregularity, and more recently the S422L-KCNJ8 mutation causing the alteration in the lK-ATP channels, associated with arrhythmic cardiac mortality. It is concluded that not all patients with this syndrome are at risk of arrhythmic events or sudden cardiac death, but a significant number of them are. Therefore, a great challenge for the medical community is to develop better risk stratification strategies as well as safer and more effective treatments.
Arrhythmogenic right ventricular dysplasia
Marleny Cruz Cardentey,Annerys Méndez Rosabal
Revista Cubana de Cardiología y Cirugía Cardiovascular , 2011,
Abstract: The arrhythmogenic right ventricular dysplasia is a genetic base cardiomyopathy, characterizedby the substitution of the miocardic tissue by an adipose or a fibroadipose one. Itusually affects the right ventricle, but the septum and the left ventricle can also be compromise.It is more frequent in young men and athletes. The most common clinical manifestationare ventricular arrhythmias and frequently the sudden death is the first event. In advancedstages systolic biventricular dysfunction exists. The electrocardiogram is characterizedby alterations in despolarization and in ventricular repolarization in right precordial derivations.The most validated image techniques for their diagnosis are the ecocardiogram,the ventriculography and the nuclear magnetic resonance, these might show global dilationof the right ventricle with systolic disfuntion, segmental wall motility dysfunctions and aneurismsof the wall. The dysplasia risk stratification is guided to prevent the arrhythmic sudden death. The therapeutic options include beta-blocking, group III antiarrhytmic drugs, automaticimplantable desfibrillator, radiofrecuency ablation and heart transplant. The presentreview has the objective to modernize the concepts of the entity, from the genetic, diagnostic,prognostic and therapeutic point of view.

Abstract: the hypertensive disorders of pregnancy are important medical problems that explain a great number of maternal and fetal complications. preeclampsia is the most severe of the hypertensive complications of pregnancy and it may be catastrophic if it is not treated or if it evolves towards eclampsia. the adequate treatment requires to have in mind the normal changes of arterial hypertension and of the intravascular volume taking place during pregnancy. preeclampsia is characterized by an extreme vasoconstriction, increase of the vascular reactivity and decrease of the intravascular volume. the greatest challenge is to face the treatment, due to the fact that two lives are at risk and that no studies of prolonged surveillance have been conducted with the different antihypertensive drugs. in this review, a treatment is proposed and the fundamental therapeutic guidelines are discussed based on the correct utilization of the main milestones of antihypertensive therapy with efficacy and recognized safety, inlcuding methyldopa, hydralazine, a and b blockers (labetalol), calcium antagonists and betablockers.

Fernández Arias,Manuel Antonio; Vázquez Vigoa,Alfredo; Roselló Azcanio,Yamilé; álvarez Batard,Germinal; Martínez Fernández,Liodelvio; Méndez Rosabal,Annerys;
Revista Cubana de Medicina , 2007,
Abstract: here is the case of a man with refractory blood hypertension secondary to aorta coarctation diagnosed at the age of 41 years. this patient had had a history of blood hypertension since he was 19 years-old but he had not managed to get his blood pressure figures under control despite hypertensive therapeutics comprising 3 drugs and one diuretic. on physical exam, there were no femoral, popliteal and pedo bilateral pulses and the fall in blood pressure of lower limbs was marked, so these elements strongly indicated aorta coarctation. comments were made on diagnostic tools like echodoppler applied to the lower limbs, thoracic radiography, echocardiogram, angiography and aortography for the diagnosis of these cases. it was concluded that coarctation of the aorta is a curable cause of secondary blood hypertension that, though rare, should be taken into account in the event of a young patient with high blood pressure and that a detailed physical exam including pulse palpation and blood pressure taking in the lower limbs is almost an imperative in order to make an early diagnosis and avoid potential complications.

Ferrer Santos,Vania; Domínguez Hernández,Mileidys; Méndez Rosabal,Ariadna;
Revista Cubana de Medicina Militar , 2011,
Abstract: introduction: high blood pressure is a major risk factor on the morbidity and mortality of cardiovascular origin according to the death certificate, objective: to assess the repercussion of this risk factor as cause of death. methods: a retrospective and descriptive study was conducted in patients deceased with high blood pressure between 2002 and 2007. study variables were: age, sex, skin color, direct cause of death, basic cause of death, contributing cause of death and clinical/pathological correlation. results: there found that the 9.1 % of deceases were hypertensive, the more involved age group was that of 65-74 years (23.4 %) and the mean age was of 65 years. in 248 deceased there was a total diagnostic coincidence in relation to the direct cause of death (74.6 %) and in 236 deceased in the basic cause of death (71.0 %). high blood pressure was the basic cause of death in the 59.3 % and the contributing cause of death in the 18.97 %. in more than a half of cases, high blood pressure was involved in the death mechanisms through the basic and the contributing cause of death. conclusions: high blood pressure is a causal determinant factor in the mortality and the progression of atherosclerotic vascular damage.

Revista Cubana de Medicina Militar , 2011,
Abstract: Introducción: la hipertensión arterial constituye el factor de riesgo mayor sobre la morbilidad y mortalidad de causa cardiovascular, estimado a través de los certificados de defunción. Objetivo: evaluar la repercusión de este factor de riesgo como causa de mortalidad. Métodos: se realizó un estudio descriptivo, retrospectivo de los pacientes fallecidos con hipertensión arterial entre el 2002 y 2007. Las variables estudiadas fueron: edad, sexo, color de la piel, causa directa de muerte, causa básica de muerte, causa contribuyente de muerte y correlación clínica/patológica. Resultados: se encontró que el 9,1 % de los fallecidos eran hipertensos, el grupo de edad más afectado fue el de 65 a 74 a os (23,4 %) y la edad promedio fue de 65 a os. En 248 fallecidos existió coincidencia diagnóstica total en la causa directa de muerte (74,6 %) y en 236 en la causa básica de muerte (71,0 %). La hipertensión arterial constituyó la causa básica de muerte en el 59,3 % y la causa contribuyente de muerte en el 18,97 %. En más de la mitad de los casos, la hipertensión arterial participó en los mecanismos de muerte a través de la causa básica de muerte y causa contribuyente de muerte. Conclusiones: la hipertensión arterial constituye un determinante causal en la mortalidad y progresión del da o vascular aterosclerótico.

Abstract: the existance of an ascending line of development of the abilities to interview and of the quality of the medical history taken by students on advancing in the medical career is expected. in order to compare the quality of the medical history recently taken by third- and six-year medical students, 19 patients were sequentially interviewed by the same number of students of each year. the newly taken medical histories were compared taking into consideration qualitative and quantitative criteria. generally, the medical history taken by the interns were of better quality, mainly because they got more primary information and established the chronopathogram of the clinical data in a better way, excepting 4 cases in which those of the third year were slightly higher. in the rest of the 15 reviewed medical histories, the quality of the interns was significantly higher in 7 and, fundamentally, in one. in the other 7 there was a mild superiority. emphasis is made on the need to continue teaching and evaluating the abilities to interview at every level of the clinical area and on seeking the most efficient methods to attain it.
Peligros biológicos e inocuidad de alimentos
Alfredo Rodríguez Matos,Emilio Guzmán Torres,Armando Escalona Rosabal,Mario Otero Fernández
REDVET , 2005,
Abstract: I.- Introducción Cuando un consumidor adquiere un alimento, descuenta que la inocuidad o seguridad del mismo está siempre presente, las expectativas y actitudes de los consumidores están dirigidas a exigir el derecho a la protección de la seguridad, la salud y la información básica sobre los alimentos que el mercado pone a su alcance. En opinión de Erro (2002), la inocuidad se transforma entonces en una “necesidad implícita” que obviamente se pretende satisfacer, pero la toma de conciencia de esto se da, lamentablemente, cuando aquella dejó de estar presente. Remitiéndonos a lo expresado por el Codex Alimentarius (1997), indica que las enfermedades de transmisión alimentaria y los da os provocados por los alimentos son, en el mejor de los casos desagradables, y en el peor pueden ser fatales. El deterioro de los alimentos ocasiona pérdidas, es costoso y puede influir negativamente en el comercio y la confianza de los consumidores. Por consiguiente, es imprescindible un control eficaz de la higiene, a fin de evitar los da os ocasionados por los alimentos y por el deterioro de los mismos, para la salud y la economía. Todos, fabricantes, elaboradores, manipuladores y consumidores de alimentos, tienen la responsabilidad de asegurarse de que los alimentos sean inocuos y aptos para el consumo. La responsabilidad del control de los riesgos microbiológicos recae sobre los individuos que intervienen en todas las fases de la cadena alimentaria, desde la explotación agrícola o ganadera hasta el consumidor final. Visto desde esta óptica el análisis de riesgos debería aplicarse dentro de un contexto estratégico, organizativo y operacional reconocido. Si bien en el proceso pueden haber elementos comunes, en el establecimiento de un nivel apropiado de protección los enfoques de esos sectores pueden presentar las máximas diferencias (FAO 2003).
