La mortalidad de la neumonía adquirida en la comunidad (NAC), en especial la neumocócica, es de alrededor de 5%; cuando se evidencia bacteriemia, hasta 20%; y, en casos de meningoencefalitis, 30%. Sin embargo, la mortalidad de la neumonía neumocócica puede llegar hasta 80% en pacientes inmunocomprometidos, esplenectomizados y ancianos.

En esta revisión actualizada presentamos los principales aspectos históricos, epidemiológicos, clínicos, terapéuticos y medidas de control y prevención de esta nueva enfermedad conocida como SRAS ( Síndrome Respiratorio Agudo Severo), que se ha considerado como la primera enfermedad infecciosa de origen viral epidémica del siglo XXI afectando principalmente áreas de China, incluyendo Taiwán y Hong Kong, así como Vietnam, Singapur y Canadá (Toronto). El agente viral causante de esta enfermedad es un nuevo coronavirus. El tratamiento mas efectivo aun no ha sido definido.

Introduction: enlargement of superficial lymph nodes is a frequent clinical finding which may be among the first evidences of a significant illness or of a specific clinical syndrome.Objective: exploring clinico-pathological relationships in patients consulting for the first time with a clinically detectable lymphadenopathy and no defined diagnosis.Materials and Methods: cross sectional prospective study including patients with clinically detectable lymphadenopathy (nodes over 1 cm in diameter) and often also suspicion of tuberculosis. Lymph node biopsies, fine needle aspirations, and other contributing diagnostic tests were performed. A histopathological classification was structured to arrange the information on the patients and to correlate laboratory findings with clinical ones.Results: patients recruited were 154; 55 (45.5%) out of 70 patients who had a tentative diag...
