Is the decremental pattern in Lambert-Eaton syndrome different from that in myasthenia gravis?
When the decrement becomes progressively greater during low frequency RNS, the patient is more likely to have LEMS than MG, and in MG, is more likely to have MuSK antibodies.
The findings suggest that H pylori may play a role in the advanced stages of carcinogenesis. It will be of interest to investigate if the relative small proportion of type III metaplasias that actually progress to carcinoma show persistence of H pylori.
