ABSTRACT
La presentación de abscesos cerebrales relacionados a meningiomas es muy poco frecuente. Usualmente son causados por bacterias comunes, siendo la Nocardia un agente etiológico excepcional. Presentamos la primera descripción en Paraguay de un absceso cerebral a Nocardia Spp asociado a meningioma en un paciente inmunocomprometido por consumo prolongado de corticoides (dexametasona).
The presentation of cerebral abscesses related to meningiomas is very rare. They are usually caused by common bacteria, nocardia being an exceptional etiological agent. We present the first description in Paraguay of a cerebral abscess to Nocardia spp associated meningioma in an immunocompromised patient for prolonged corticosteroid consumption (dexamethasone).

Resumen La nocardiosis es una infección localizada o sistémica que afecta principalmente a pacientes inmunocomprometidos, siendo la localización pulmonar el sitio más frecuente. La transmisión proviene principalmente de la inhalación de esporas o mediante la inoculación directa en la piel y mucosa ocular. Se han descrito más de 90 especies de Nocardia, de éstas más de la mitad son reconocidas como patógenos en humanos. Las especies de importancia médica más conocidas son Nocardia farcinica, Nocardia abscessus, Nocardia nova y Nocardia brasiliensis. En Chile hay casos publicados de infección por Nocardia asteroides y N. farcinica. Nocardia cyriacigeorgica se considera una especie emergente, no habiendo casos descritos previamente en nuestro país. Presentamos el caso clínico de una nocardiosis pulmonar en un paciente con síndrome de inmunodeficiencia adquirida (SIDA).
Abstract Nocardiosis is a localized or systemic infection that mainly affects immunocompromised patients, with pulmonary localization being the most frequent site. The transmission comes mainly from the inhalation of spores or by direct inoculation into the skin and ocular mucosa. More than 90 species of nocardia are described, of which more than half are recognized as pathogens in humans. The best known species of medical importance are Nocardia farcinica, Nocardia abscessus, Nocardia nova y Nocardia brasiliensis. In Chile, there have been published cases of Nocardia asteroides and Nocardia farcinica infections. Nocardia cyriacigeorgica is considered an emerging species, there being no cases previously described in our country. We present a clinical case of pulmonary nocardiosis in an acquired immunodeficiency syndrome (AIDS) patient.

Pulmonary nocardiosis is an uncommon bacterial infection that may lead to severe disease in immunocompromised patients. The disease is rare in immunocompetent patients. Reported cases are few, and the literature is limited because disease recognition is difficult. We present a case report of two patients of pulmonary nocardiosis, who had different clinicoradiological presentations and also responded differently to treatment. Given the rising incidence of cancer, organ transplantation, and use of parenteral steroids, Nocardia is likely to attain a higher place among the causes of pulmonary infections.
ABSTRACT
We present the case of a 62-year-old male with chronic obstructive pulmonary disease and poorly controlled diabetes mellitus who presented with haemoptysis. A radiograph of the chest showed a right lower parahilar opacity which on the contrast enhanced computed tomography was seen to be an irregular, spiculated mass localised to the middle lobe. Considering malignancy as the most probable diagnosis, a bronchoscopic endobronchial biopsy was performed which surprisingly established pulmonary actinomycosis as the diagnosis. The patient was successfully managed with amoxicillin and clavulanic acid and glycaemic control.
ABSTRACT
Resumen La nocardiosis es una rara infección oportunista que afecta principalmente a pacientes con alteración de la inmunidad celular, como pacientes con síndrome de inmunodeficiencia adquirida o postrasplantes. El compromiso del sistema nervioso central es generalmente como absceso y menos frecuentemente como meningitis primaria. El presente artículo hace el reporte de un caso de meningitis primaria por Nocardia en paciente inmunocompetente y revisión de la literatura.
Nocardiosis is a rare opportunistic disease that affects mainly patients with deficient cell-mediated immunity, such as those with acquired immunodeficiency syndrome (AIDS) or transplant recipients. The central nervous system presentation is as cerebral abscesses and less frequently, as primary meningitis. Here, a case of primary nocardia meningitis is described in a patient without a predisposing condition, along with a literature review.

Two strains of Nocardia spp. were isolated from bovine milk of two individual bulk tank. Molecular identification classified the strains as Nocardia farcinica and Nocardia cyriacigeorgica. The thermorresistance to boiling of the isolates was carried out and was observed bacterial growth after boiling. Our findings indicate the potential risk of pathogen transmission to humans through contaminated milk with Nocardia spp.
