Prednisone 0.25 mg/kg per day<br />was administered. The generalized dermatitis regressed<br />in a month (Fig. 2) and patch testing showed delayed<br />sensitization to paraphenylendiamine (PFD) and benzocaine.<br />The final diagnosis was allergic contact dermatitis<br />due to PFD. }, number={1}, journal={European Journal of Pediatric Dermatology}, author={Milano, A. and Bonifazi, E.}, year={2011}, month={Mar.}, pages={ 55} }
