Licorice that has the active ingredient of glycyrrhiza can have serious side effects. Another type of licorice, called DGL or deglycyrrhizinated licorice, doesn't seem to have the same side effects and is sometimes used to treat peptic ulcers, canker sores, and reflux (GERD).
Myelodysplastic syndromes (MDS) can be associated with systemic or autoimmune diseases. Vasculitides (leucocytoclastic, periarteritis nodosa, micropolyangeitis, Wegener's granulomatosis), relapsing polychondritis, and Sweet's syndrome are the most commonly reported.
Myasthenia Gravis is an autoimmune disease in which antibodies damage the acetylcholine receptors and compromise the muscle side of the nerve-muscle communication point. LEMS is an autoimmune disease that affects the nerve and not the muscle. LEMS may be triggered by a lung cancer. An EMG test performed by an experienced neurologist differentiates Myasthenia Gravis from LEMS. Blood tests for certain antibodies may also help with their differentiation.
