Abstract:
In this study, the effect on olfaction of surgical procedures, performed distant to the nose, was analyzed. Twenty-three patients planned for surgery of minor or moderate degree under general anaesthesia were examined before surgery for evaluation of sense of smell with the University of Pennsylvania Smell Identification Test and a smell threshold test (Olfacto-Labs). Reexamination was performed 24–48 hours postoperatively. Both tests demonstrated significant improvement in olfaction following surgery. The improvement was more obvious in younger patients and in patients undergoing moderate sur

Abstract:
In patients with chemosensory complaints, a head-to-head comparison of unilateral olfaction threshold testing with the Phenyl Ethyl Alcohol Smell Threshold Test (PEA) and the OLFACT-RL Odor Threshold Test (OLFACT-RL) was undertaken. The charts of 23 consecutive patients presenting with chemosensory complaints seen at the Smell and Taste Treatment and Research Foundation were reviewed and information extracted per Institutional Review Board guidelines. All patients had undergone olfactory testing with the PEA test and the OLFACT-RL test in accordance with their published administration manuals.

This work aims to advance understanding of the differentiation of mushroom species through electronic devices that use sensors of various technologies and techniques for pattern recognition, comparing mainly volatile substances that emanate from them. In this first phase, the capacity of human olfaction to differentiate between the smell released by different wild mushrooms of the genus Amanita was analyzed by means of a triangular sensory test, comparing later the data to those obtained for the same samples with an electronic nose in a similar test.

Participants completed the Brief Smell Identification Test at the year 3 clinic visit in 1999-2000. Olfaction was defined as good (test score 11-12), moderate (9-10), hyposmia (7-8), or anosmia (0-6). Cognitive function was assessed using the Modified Mini-Mental State examination (3MS) up to 5 times at clinic visits in ye

Abstract:
Aims: Peculiar characteristics of migraine headaches include the arousal of olfaction during the attacks and osmophobia. We performed an olfactory test to evaluate the association between olfaction and migraines. Methods: We evaluated olfactory dysfunction in 80 migraine patients (31 experienced migraines with aura (MWA), 49 migraine without aura (MWOA)) and 30 healthy controls. Participants were assessed for concurrent osmophobia. Olfaction was evaluated using an odour stick identification test (OSIT), in which participants were asked to identify various odours during a migraine-free period.

Moreover, although to some extent smell remains a mystery, the chapter emphasizes that scents have always been an integral part of peoples' lives, possessing distinctive and often shared meanings. For example, odor has been intimately associated with notions of identity. Although denigrated and regarded with suspicion, smell
