Lyme disease is still a clinical diagnosis. Still no agreement from the CDC that Master's and Lyme diseases are one and the same. The possibility that they are both clinically indistinguishable but caused by variants of similar organisms exists. The borrelia found is not typical of North American forms described so far. Differentiation of EM vs. brown recluse spider bite was demonstrated.
Spider bite is extremely painful.
The bite is not usually in the center of the lesion. The first known locally acquired case of Lyme arthritis in B.C. was described. Comment was made that compared to other areas there are few cases of arthritis caused by Lyme disease in British Columbia. No explanation is yet offered. First, second and third degree heart block are described with third degree being most common.
