Fiebre en el viajero: actuación en urgencias / Fever in a traveller: what to do in the Emergency ward

El aumento de los viajes internacionales ha incrementado el número de casos de enfermedad asociada a los viajes. La fiebre es uno de los motivos de consulta más frecuentes de los viajeros, y estos pueden acudir en primera instancia a un Servicio de Urgencias Hospitalario (SUH). El médico de urgencias debe reconocer las enfermedades de elevada morbimortalidad y las que representan un peligro para la salud pública. Aunque la lista de causas de fiebre en el viajero (FV) es larga, un método de trabajo basado en restringir las posibilidades diagnósticas en función de la clínica, el período de incubación y la zona visitada, permite orientar la mayoría de los casos. La malaria es la causa más frecuente de FV y su mortalidad es relevante, por lo que debe ser el diagnóstico por defecto. El dengue es una enfermedad reemergente que debe considerarse después de la malaria en el diagnóstico diferencial de la FV (AU)

Salmonella endocarditis presenting as cerebral hemorrhage.

The case of a 35-year-old male with cerebral hemorrhage as a presenting complication of infective endocarditis of the aortic valve, caused by Salmonella typhimurium, is described. We emphasize the infrequent etiology and review the mechanisms of intracranial hemorrhage in infective endocarditis.

[Coronary transluminal angioplasty using 6-french diagnostic catheters. A preliminary study]. / Angioplastie transluminale coronaire avec des cathéters-guides 6 french. Etude préliminaire de faisabilité.

This preliminary study was undertaken to assess the potential indication and limitations of the use of 6 French guiding catheters for percutaneous transluminal coronary angioplasty (PTCA). Between September 1992 and October 1993, 100 consecutive patients with an average age of 64 +/- 11 years underwent 6 F angioplasty for: stable angina (38.7%), unstable angina (32.4%), non Q-wave or infarction recanalized by thrombolytic therapy (18%), and acute myocardial infarction (10.8%). Eighty per cent of the pTCAs were performed immediately after diagnostic coronary angiography. Single vessel disease accounted for 93.7% of cases. Of the 118 lesions treated, 46.6% were types A or B1, 44.9% were type B2 and 8.4% were type C. The success rate of 6 F PTCA was 96.4% using an average of 1.08 guides and 1.25 balloon catheters per patient. Stenosis decreased from 83 +/- 10% to 26 +/- 16%. There were 4 technical failures: in 1 case it was not possible to pass a chronic occlusion, in 1 case coronary dissection was complicated by infarction, and in 2 cases a 7 F guiding catheter was required for successful PTCA. No patients required emergency coronary bypass surgery and there were no fatalities during the procedure. Four patients required perfusing balloon catheters and 8 were stented with a Palmaz-Schatz endoprosthesis with the 6 F catheter. These results are comparable to those obtained with larger diameter guiding catheters. In view of the good coronary ostial tolerance, the lower rate of local complications at the site of arterial puncture and the possibility of earlier mobilisation of patients after the procedure, the indications for 6 F PTCA should increase.
