Jl. Izquierdoalonso et al., SEVERE UPPER AIRWAY-OBSTRUCTION IN ESSENTIAL TREMOR PRESENTING AS ASTHMA, The European respiratory journal, 7(6), 1994, pp. 1182-1184
A 57 year old man with essential tremor (ET) presented with a 2 year h
istory of paroxysmal attacks of dyspnoea and wheezing. He had been dia
gnosed as having bronchial asthma, and propanolol was excluded from hi
s treatment. Flow-volume loops showed abrupt changes in maximum flows,
with poor reproducibility. A diagnosis of functional upper airway obs
truction was confirmed by fibreoptic bronchoscopy. The importance of e
stablishing the precise diagnosis, in order to provide appropriate tre
atment, is emphasized.
