Pruritus ani.

BACKGROUND

Pruritus ani is a common presenting problem in general practice, one that is particularly distressing to patients. However, there is little available research on which to base management

OBJECTIVE

This article discusses the causes and management of this distressing symptom based on thecurrent available evidence.

DISCUSSION: Perianal itch probably arises from localised inflammation. This may be the result of anorectal disease, skin disorders, excessive cleaning, application of local irritants or other causes. In children, perianal itch may be caused by intestinal hermetic Infection such as pinworm. Whatever the initial cause, the problem may at times become chronic, with scratching inflaming the area and more itching resulting. Avoiding trauma from excess washing, toilet paper and topical agents is important. Treatments likely to be effective are emollients such as sorbolene, a short course of topical hydrocortisone cream and capsaicin cream.
