Lower oesophageal sphincter supersensitivity to gastrin I and cholinergic stimulation has recently been described in patients with achalasia. To determine the pathogenesis of this finding, the lower oesophageal sphincter was tested to a cholinesterase inhibitor, edrophonium chloride. Edrophonium chloride significantly increased the lower oesophageal sphincter pressure both in normal subjects and in patients with achalasia. The preservation of this response in the presence of denervation supersensitivity suggested intact postganglionic cholinergic nerves and, thus, a preganglionic site of denervation in achalasia.

A patient was a fifty-year-old man, who had a 35 year-history of facioscapulohumeral muscular dystrophy (FSHD). He was admitted to our hospital because of acute progressive weakness involving his lower extremities without any fluctuation in the recent 3 weeks. We clinically followed him for 30 years and he was able to do all daily activities, walked alone, drove a car and climbed stairs with a handrail. His 76-year-old mother had about 60 year-history of FSHD and could walk with support. On admission, neurological examination revealed moderate to marked muscle weakness and atrophy of the face, limb-girdle and all extremities, predominantly in the upper proximal limbs. He could hardly stand and needed a stick for walking. He had no blepharoptosis or ocular movement disturbance, and did not complain of difficulties in swallowing and chewing. CK values and other laboratory data were normal, and serum anti-Jo-1 antibody, anti-SSA/Ro antibody and anticardiolipin IgG antibody were negative. Because EMG examination revealed myopathic changes and an X-ray examination of the lumbar spine was normal. Thus, polymyositis and neurologenic disorders were ruled out. Disturbance in chewing and swallowing, that were uncommon in FSHD, appeared about a month after admission. Repetitive stimulation test revealed typical waning pattern. Edrophonium chloride injection was effective for decreased waning and the clinical symptoms. The titer of serum anti-ACh receptor antibody was 97 nmol/l, confirming the diagnosis of myasthenia gravis. Because of fluctuated dyspnea, thymectomy was done and his condition gradually relieved after administration of corticosteroid and choline esterase inhibitor. From this experience, we learned that we have to consider other neuromuscular disorders, even rare ones, if there existed unusual weakness of underlying muscular dystrophy.
