Head and neck manifestations of eosinophilia-myalgia syndrome.

Abstract

Eosinophilia-myalgia syndrome (EMS) is a multisystemic disease that occurs in patients who have consumed products containing L-tryptophan. Prominent features include incapacitating myalgias, arthralgias, neuropathies, and eosinophilia. Despite the frequent association of dysphagia, dyspnea, and the potential for aspiration, the otolaryngology literature is devoid of information on EMS. In order to determine the frequency of otolaryngic symptoms, questionnaires were distributed to patients with EMS in 33 different US states. Among the 28 various head and neck manifestations studied, 70% of EMS patients complained of generalized muscle spasms, 66% xerostomia, 62% dyspnea, and 56% dysphagia. In addition, the epidemiology, clinical presentation, diagnostic criteria, and treatment options are discussed. This paper assesses the frequency of otolaryngic manifestations of EMS, as well as introduces this syndrome to the otolaryngologist-head and neck surgeon. It is important for the otolaryngologist to be aware of EMS and its manifestations and treatments so that patients with this potentially lethal disease can receive appropriate evaluation and expeditious treatment.
