The Clinical Spectrum of Staphylococcus aureus Pulmonary Infection

Pneumonia estafilocócica adquirida na comunidade

“…(14,15) The percentage found in this study sample is in accordance with the variation shown in other studies. (1)(2)(3)(4)(5)(6)(16)(17)(18)(19) The infection typically affects elderly individuals with preexisting chronic pathologies such as COPD, cardiovascular diseases, alcoholism and diabetes mellitus, as well as hemodialysis patients with chronic kidney disease. (2,4,6) Young or previously healthy individuals can also be affected, principally when they present predisposing factors such as skin infections (impetigo, abscess, cellulitis, furunculosis or infected wound) or infections of the genital tract associated with septic abortion, all of which represent hematogenous dissemination of the infection.…”

“…(1)(2)(3)(4)(5)(6) In 55% of cases, infection results from aspiration of naso-oropharyngeal secretions colonized by Staphylococcus …”

“…(8,9) Its presentation is typically severe, with a clinical course that varies from subacute to fulminant, regardless of the previous health status of the patient. (2,10) There have been few case-series studies that exclusively address community-acquired staphylococcal pneumonia. (4,6,7) The objective of this study was to describe the clinical, radiological and epidemiological characteristics of staphylococcal pneumonia in a study of 24 cases diagnosed in immunocompetent patients, nonusers of intravenous drugs, from the community and requiring hospitalization.…”

Neumonías en el inmunocomprometido: perspectiva desde el diagnóstico por imágenes, e inferencia Bayesiana

“…Kaye y cols. (1990) 32 , comunicaron consolidaciones multilobares en 60% y 39% con compromiso bilateral. Los abscesos son comunes, en 15 a 30% y el neumatocele en 50% de los niños y 15% de los adultos.…”

“…Los abscesos son comunes, en 15 a 30% y el neumatocele en 50% de los niños y 15% de los adultos. La efusión pleural ocurre en 30 a 50% de los pacientes y cerca de la mitad de éstos con carácter de empiema 31,32 . En hospederos inmunocomprometidos, la neumonía por S. aureus puede seguir el patrón clásico, por ejemplo en pacientes con SIDA, receptores de trasplantes sólidos e inmunocomprometidos leves 15 .…”
