Large doses of CORTICOSTEROIDS, coupled with IMMUNOSUPPRESSANT treatment, usually curtail the disorder. Recovery occurs in about 50 per cent of cases.... polyarteritis nodosa

a condition in which the hairs break easily. It may be due to a hereditary condition or it may occur as a consequence of repeated physical or chemical injury. The latter condition may follow the use of heat or bleach on the hair or be caused by persistent rubbing.... trichorrhexis nodosa
