[Autochthonous mycetoma caused by Petriellidium boydii (author's transl)]. / Micetoma autóctono por Petriellidium boydii.

A case of authochthonous mycetoma with Petriellidium boydii as the causal agent, located in the third distal of the lower left leg is reported. The patient was a 35 year old male without any associated pathology. It is assumed that the infecting organism entered the tissues through a lesion caused a few years previously during a traffic accident. On admittance patient was found to have two fistulas on the upper part of the external malleolus from which pus with small yellow granules measuring 1 to 1.5 mm in diameter discharged. Fungus was repeatedly isolated in pure culture in all media in which is was sown. Mycological study of the isolated fungus and histopathology of the lesion are presented. The fungus proved in vitro to be sensitive to miconazole nitrate with minimal inhibitory concentration and minimal fungicide concentration values of less than 0.1 microgram/ml. The third distal of the peroneal bone was excised and arthrodesis of the ankle practiced as conservative treatment and miconazole administered intravenously, Eighteen months later clinical evolution is satisfactory.

[Urinary infection in patients with short-term bladder catheterization]. / Estudio de la infección urinaria en pacientes con sondaje vesical de corta duración.

BACKGROUND: The aim of the study was to assess the number of urinary tract infections, the time between catheterization and the development of bacteriuria, the route taken by the microorganisms and the clinical relevance of infection in patients with bladder catheterization during a short time. METHODS: 83 patients were evaluated by urine culture from the bladder, urethra, the connection of the catheter and the collecting system, and the collecting bag, on a daily basis during the 5 initial days, with clinical and microbiological follow up to 7 days after the removal of the catheter. RESULTS: 32% of patients developed bacteriuria. The mean interval between catheterization and the development of bacteriuria was 4.1 days. 45% of them were detected within 48 hours after catheter insertion. In 50% the causative organisms were detected in the urethra at least 24 hours previously. In no case the microorganism isolated from the connection between the catheter and the collecting system was subsequently isolated form bladder urine. Bacteriuria disappeared spontaneously in 27% of cases. Antibiotic therapy was necessary in 42%. CONCLUSIONS: In the study population most urinary infections were due to previous urethral colonization and subsequent dragging into the bladder, in many cases at the same time of catheterization. A non-negligible number of bacteriurias disappeared spontaneously.
