Problem: Your patient is a 10-month-old child Poppy who has eczema in the cubital fossa of their knees and elbows; they also have infected nappy rash caused by Candida albicans. Poppy's parents have been applying a prescribed topical eczema medication (Betamethasone dipropionate 0.05%) to the nappy rash hoping it will work the same way as it did on the eczema.
Explain how the mechanism of action of this medication has led to an infected nappy rash.
