[Febrile syndrome of unknown etiology].
The results of the analysis of 114 patients with fever over 38 degrees C with minimal duration of one week, are reported. There were no data from the physical examination to produce a nosological diagnosis. The greater number of age groups were for infants (43%) and school children (35%). There was a predominance in males (62.3%). There were histories of potential usefulness for the diagnosis in 39 patients, but only in 7 cases was it possible to establish a relationship with the illness. In 70 patients (61.4%) it was not possible to determine exactly the cause of fever. In the remaining cases, a distribution into three etiological groups was made: infectious or parasitic, collagenous disease and malignant neoplasia. Considerations are made on these groups and on the usefulness, for the diagnosis, of the type of fever graph. The course is analyzed and conclusions are established.
