WebbEaton-Lambert syndrome is due to impaired acetylcholine release from presynaptic nerve terminals. Repetitive nerve testing at rapid rates (20 to 50 hertz [Hz]) or a single supramaximal stimulation before and after 10 seconds of maximal isometric exercise shows an incremental response of up to 400%. WebbAesthetic treatments are increasingly in demand, particularly in western countries, these can be divided into treatments such as fillers, botulinum toxin or laser therapy ( Table 1 ). Dermatological consequences are among the greatest stresses in cancer patients because they are a persistent sign of cancer ( Table 2 ).
