Enterococcus spp. and Streptococcus spp. bloodstream infections: epidemiology and therapeutic approach.

Streptococcus spp. and Enterococcus spp. are frequent etiologies of bloodstream infection and endocarditis. In recent years, the incidence of Enterococcus spp. has been increasing, especially with nosocomial involvement, and with a high mortality rate. In this entity, the risk of endocarditis and its relationship with colorectal neoplastic pathology remains to be clarified, in order to establish indications for echocardiography and colonoscopy. In the case of Streptococcus spp., the risk of endocarditis depends on the species and the mortality rates are usually lower. Finally, in recent years, the treatment of endocarditis has been directed towards oral consolidation regimens and new long-term antibiotic treatments.

Infección por Nocardia en pacientes trasplantados cardiacos / Nocardia infection in heart transplant recipients

Introducción. La incidencia de la infección por Nocardia en pacientes trasplantados oscila entre el 0,7–3% y conlleva una mortalidad elevada (26–63%). Este artículo pretende precisar las características epidemiológicas, clínicas y evolutivas de los pacientes con transplante cardiaco que desarrollan nocardiosis en nuestro medio. Métodos. Cohorte retrospectiva de 570 pacientes trasplantados cardiacos. Se revisan las historias clínicas de aquellos en los que se realizó el diagnóstico de infección por Nocardia durante el seguimiento y se registraron datos demográficos, antecedentes personales, régimen de inmunosupresión, profilaxis antibiótica, episodios de rechazo, infecciones asociadas, así como, lugar de la infección por Nocardia, tratamiento administrado y evolución. Resultados. Se identificaron 4 casos con nocardiosis (incidencia del 0,73%), siendo en 2 de ellos diseminada. En todos hubo afectación pulmonar. La mortalidad fue elevada (2 de los 4 pacientes). Conclusión. En pacientes trasplantados cardiacos la infección por Nocardia es poco frecuente y conlleva una elevada mortalidad. Sería necesario un diagnostico precoz para instaurar un tratamiento adecuado(AU)

Introduction. The incidence of Nocardia infection in transplant patients ranges between 0.7 and 3% with a high mortality (26–63%). This fact, together with a median time to diagnosis in about two weeks ago that the state of alertness is of vital clinical importance. Methods. From a cohort of 570 cardiac transplant patients, we reviewed the medical records of those who underwent the diagnosis of Nocardia infection during follow-up. Results. We identified four cases (incidence 0.73%), two scattered. In all, had pulmonary involvement. Mortality was high (2 of 4 patients). Conclusion. In cardiac transplant patients Nocardia infection is rare but has a high mortality, being necessary an early diagnosis to establish an appropriate treatment(AU)

Mucormycosis of the paranasal sinuses.

Between 1989 and 1992 we had two cases of mucormycosis. The first patient presented with left hemiplegia: radiologic studies showed a right sphenoidal sinus mass, cerebral ischaemic infarction and occlusion of the right carotid artery. The second patient was seen with an abscess of the hard palate after long term steroid therapy. CT scan showed a soft-tissue mass occupying the maxillary sinus, which had eroded its walls and spread to palate, orbit and ethmoidal cells. We have emphasised the presence of hyperglycemia in both cases, the marked tendency of this lesion to invade blood vessels, and the good results obtained by combining liposomal amphotericin B with radical surgical debridement.

Contribution of one case of spontaneous bilateral perirenal haematoma (SBPH) in a patient infected with the human immunodeficiency virus (HIV). The haematoma etiology was a nodose panarteritis (NPA). Etiological diagnosis was established by arteriography, but abdominal computerized tomography (CT) and renal ultrasound scans were useful diagnostic tools. A relationship between human immunodeficiency virus and NPA pathoetiology is suggested and commented upon.
