Summary

Scabies and lice occur worldwide. In infants and young children scabies nodules and vesiculopustular lesions on the palms and soles are frequently present in addition to widespread excoriated papules, and secondary staphylococcal or streptococcal impetigo is common. A diagnosis of scabies is established by clinical detection of the characteristic burrows and, if possible, microscopic identification of the mite, eggs and scybala. The current treatment of choice is topical permethrin 5% cream, with oral ivermectin an alternative option for recalcitrant cases. Head lice are found commonly in schoolchildren. Extensive use of insecticide treatment has resulted in selection of lice with resistant mutations. As a consequence, there has been considerable interest in development of alternative and physical treatments. Folliculitis caused by the Demodex mite is primarily seen in children with acute lymphoblastic leukaemia on maintenance chemotherapy. The papulopustular eruption on the face and scalp may be resistant to treatment.
