Pulmonary nocardiosis in heart transplant recipients: treatment and outcome.

Background: Nocardial infections typically affect patients receiving immunosuppressants, occurring early after surgery in 3% to 40% of heart transplant (HTx) recipients. The emergence of antibiotic resistance and occurrence of disease recurrences in AIDS population has engendered controversy about the treatment for immunodepressed HTx patients.

Methods: We present a retrospective study of the diagnosis, treatment and outcome of 560 HTx recipients between 1984 and 2002.

[Aspergillosis in pulmonary transplantation].

Background: Fungal infections are a frequent cause of morbidity an mortality in transplant recipients. Aspergillus spp. is an ubiquitous fungus capable of producing diverse clinical entities with varying severity.

[Septic arthritis caused by Streptococcus pneumoniae].

Background: Streptococcus pneumoniae is an uncommon agent of infective arthritis. In this report three cases of pneumococcal arthritis are described.

Methods: Retrospective review of synovial fluids processed in our laboratory yielding bacteria.

[Infections in lung transplantation].

Lung transplantation has become the therapeutic hope of terminal respiratory patients. Infections are among the main causes of morbidity and mortality in these patients. We therefore analyze infections suffered after lung transplants performed at Clínica Puerta de Hierro over a two-year period.

[Pyogenic liver abscess. A descriptive study of 35 cases].

Thirty-five patients with pyogenic hepatic abscess (PHA) attended over 13 years in a general hospital were studied. The aim of the study was to know the usefulness of the performance of opaque enema in patients with cryptogenic PHA and the prognosis of the patients treated with only antibiotics. The most frequent clinical and analytical manifestations were fever and leukocytosis.

[Bacteremia associated with mycotic aneurysm of the transversal aortic arch and myocarditis caused by Salmonella enteritidis].

A 60-year-old male with diabetes mellitus had Salmonella enteritidis bacteremia associated with mycotic aneurysm of the transverse aortic arc and myocarditis. Antibiotic therapy with ampicillin and chloramphenicol was ineffective despite the fact that the microorganism was sensitive in vitro to those antimicrobials, and the patient had a progressive clinical deterioration which culminated in death.

Activity of cefotaxime and amikacin against 14,272 gram-negative bacteria from clinical samples in the period 1980 to 1985.

The sensitivity to cefotaxime and amikacin of 14,272 Gram-negative bacilli (Enterobacteriaceae and non-fermenting Gram-negative bacilli) isolated from clinical samples was studied during the period 1980 to 1985. The minimum inhibitory concentration (MIC) was determined by means of diffusion in agar. Strains were considered resistant to cefotaxime and amikacin if the MIC values were greater than 16 mg/L and greater than 8 mg/L, respectively.
