Introducción: Uno de los aspectos que más interés suscita en lo referente a la distribución geográfica de la mortalidad por cáncer es la formación de conglomerados espaciales. Objetivo: Identificar el patrón espacial de la mortalidad por cáncer, cardiopatía isquémica y enfermedad cerebrovascular isquémica mediante la detección y descripción de con...

Cancer is a serious health problem worldwide. The introduction of an ecological and evolutionary perspective of malignant neoplasms is aimed at a more systemic and objective approach to the nature of this heterogeneous group of diseases. This paper will review current thinking in the ecological-evolutionary perspective of cancer. Cancer is a univer...

Introduction: Lung cancer tops the list of cancer incidence and mortality in men. It is fourth most frequent neoplasm in women, and second cause of death by neoplastic diseases in the female sex. Objectives: To determine the parameters of efficiency and the relationship between predictor variables and the risk of being diagnosed with lung cancer in...

Cancer is a serious health problem worldwide. Estimates, in terms of incidence and mortality, are not at all promising especially for underdeveloped countries. During the last decades, important contributions have been made to the understanding of human carcinogenesis, especially from the ecological and evolutionary perspective. The objectives of t...

Cancer has become the leading cause of morbidity and mortality in many countries. In recent decades there has been a change in the conceptual paradigm of neoplastic diseases, which now focuses on the ecological-evolutionary perspective of these. With the aim of analyzing, with updated elements, the relationship between the evolutionary process of t...

RESUMEN El cáncer constituye un serio problema de salud a nivel mundial. Las estimaciones, en cuanto a incidencia y mortalidad, no son nada halagüeñas, en especial para los países subdesarrollados. Durante las últimas décadas se han realizado importantes contribuciones a la comprensión de la carcinogénesis humana, sobre todo desde la perspectiva ec...

INTRODUCTION: In many countries cancer is or threatens to become the leading cause of death, although incidence and mortality rates differ between high-income and low- and middle-income countries. Developments in evolutionary biology have revealed that carcinogenesis is even more complex than previously thought. Several theories attempt to integrat...

A prospective, descriptive and longitudinal study of 62 patients with community-acquired pneumonias, admitted in "Dr. Joaquín Castillo Duany" Teaching Provincial Hospital in Santiago de Cuba was carried out from January to April, 2014, with the aim of identifying deficiencies in the use of the clinical method for an appropriate classification of th...

A literature survey on the subject was conducted in order to deepen into the physicochemical characteristics, clinical manifestations and action to take in damages caused by neuroparalyzing substances and therapeutic alternatives with the use of traditional medicine as well. Furthermore, algorithms to contribute to a better understanding of the tea...

A retrospective, descriptive and cross-sectional study was conducted in 94 patients with community-acquired pneumonias -- selected by systematic probability sampling -- admitted to "Dr. Joaquín Castillo Duany" Teaching Clinical Surgical Hospital of Santiago de Cuba during 2011 to assess the clinical applicability of the Fine index. In the series ca...

The case of an apparently healthy 40 year-old patient is reported, who was attended in "Dr. Joaquín Castillo Duany" Clinical Surgical Hospital of Santiago de Cuba to present with epigastric abdominal pain for several months, no irradiated and associated with discomfort in anterior chest, breathing difficulty, swelling of the legs, weakness, drowsin...

Advances in the cellular and molecular biology have allowed a better understanding of the meaning of cancer. Many researchers agree about an orderly and sequential occurrence of tumor progression in each of the most frequent human tumors, the presence of "gatekeeper and caretaker genes" that regulate the sense of this development, the adaptative na...

Se presenta el caso clínico de un hombre de 55 años de edad, en quien se diagnosticó en vida una polimiositis como manifestación paraneoplásica; sin embargo, como no mejoró con el tratamiento esteroideo, se complicó y falleció. El resultado de la necropsia confirmó la presencia de una neoplasia gástrica.The clinical case of a man aged 55 undergoing...
