AT PRESENT most dermatologists consider roentgen epilation the most efficient form of treatment for tinea capitis, particularly for the type caused by Microsporon audouini. In the last few years this fungus has been the predominant causative agent of the prevailing tineal infections of the scalp of children in the eastern and central parts of the country.
