Khaki Drill and Skin Irritation

Sir,?The following facts may possibly be of interest to your readers and of use in cases similar to my own. For several years I suffered from an irritating skin disease which, without pathological examination of scrapings, was diagnosed variously as " tinea" or "lichen." Various doctors prescribed various ointments ?chrysarobin, benzoic, resorcin, salicylic, etc., etc., and iodine liniment, all of which were ineffectual. I had also a good deal of X-ray treatment, which was perhaps successful in certain parts, certainly unsuccessful in others. Early in the course of the affliction I noticed a close connection between it and sweating?it often recrudesced after violent exercise, especially in damp hot weather. Recently I noticed a recurrence after wearing khaki drill or twill clothing when I had been sweating very little or not at all, and I have accordingly made experiments which to my satisfaction establish the fact that the rash was caused by khaki not by sweating, for I have sweated profusely wearing other material than khaki, both rough and smooth, without a recurrence of the rash. My original belief that the sweating caused the rash is due to the fact that I generally wear khaki (as most people do in the East) when shooting or hill climbing or riding. I shall be glad to answer any question you may care to put to me if my doing so would be of any use.?Yours, etc., H. WILKINSON, ext., i.c.s., British Envoy at the Court of Nepal.
