[RS3PE syndrome: An update on its treatment using the presentation of a case].

The present study was undertaken in order to try to clarify certain aspects of RS3PE syndrome, for which there is no unanimity of opinion in the current literature. An attempt will be made to clarify the best and most suitable drug for treatment, and the dosage duration. In order to do this, a literature search was performed, and a review is presented of the 108 cases collected. In 95% cases glucocorticoids were the most used, with prednisone in being used in 68.5% of cases. Although there is no unanimity criteria regarding the dosage and duration, 73.8% cases were treated with a prednisone dose from 15 to 20 mg/day (median 18.2 mg/day, SD 8.9). Two-thirds (66.1%) of cases were treated for 3 to 6 months (median 5.3 months, SD 3.8). A case is presented that serves as a common thread of these observations.
