We report a 5-week-old patient who developed a tracheal-wall dehiscence after a slide(More)
Patients with myasthenia gravis (MG) have increased tolerance to the neuromuscular blocking properties of suxamethonium (SCh) and decamethonium (C10) and exhibit a reversal of the C10-induced block by neostigmine. The effects of these drugs were compared in forelimb flexor digitorum longus muscle from normal rats and from rats with experimental autoimmune(More)
