RT Journal Article SR Electronic T1 Syngamosis, an unusual cause of asthma: the first reported case in Canada JF Canadian Medical Association Journal JO CMAJ FD Canadian Medical Association SP 269 OP 270 VO 132 IS 3 A1 Leers, W. D. A1 Sarin, M. K. A1 Arthurs, K. YR 1985 UL http://www.cmaj.ca/content/132/3/269.abstract AB The first case of syngamosis in a human in Canada is reported. The patient, a traveller to the Caribbean islands, presented with a chronic dry cough. The nematode Syngamus laryngeus is found in wild and domestic birds and mammals in the tropics and subtropics. Humans are only accidental hosts. The diagnosis of syngamosis is usually made by fibreoptic bronchoscopic examination, which reveals the Y-shaped worms in the bronchi or the characteristic eggs in the sputum or feces. Physicians must be alerted to the possibility of syngamosis in patients with symptoms of asthma who have recently travelled to South America or the Caribbean islands.
