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.

Abstract:

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.

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.

A new Korean culturefriendly olfactory function test, the YSK olfactory function test (YOF test, Kimex Co.), uses safe odorants, such as phenyl-ethyl alcohol (PEA) (not n-butanol), for the threshold test.

In multivariable linear regression models, higher FA in several regions was associated with better olfaction, with the strongest association in the stria termina

Abstract:

While measures to detect psychophysical olfactory ability are a crucial part of clinicians’ assessment of potential olfactory loss, it gives no indication of how olfaction is experienced by the patient and these different aspects often deviate substantially. To ensure quality and reproducibility of subjectively reported olfactory experience and significance, the Importance of Olfaction Questionnaire (IO-Q) was introduced around a decade ago, and while initial validations have produced promising results, important aspects remain nearly unexamined. For example, the test-retest reliability has ra

Abstract:

A growing body of literature suggests a close link between olfaction and social expertise. The current study examines whether mentalizing skills are related to olfactory discrimination performance. In order to assess their mentalizing ability, 21 women and 20 men completed the “Reading the Mind in the Eyes” test (RMET). Here, the participants have to infer other persons’ mental state from photographs of eye regions. Odor discrimination was assessed using the “Düsseldorf Odour Discrimination Test” (DODT). The DODT consists of 15 items, each containing mixtures of four monomolecular substances.

Abstract:

A detailed preoperative and postoperative examination of the olfactory function of 111 patients with chronic polypoid ethmoiditis was carried out. Eighty-seven patients required a complete endoscopic endonasal sphenoethmoidectomy. In 24 patients an endoscopic partial resection of the ethmoidal cell system was performed. Before surgery a normosmia was ascertained in 39 patients (35%). Thirty-four patients (31%) were hyposmic, and 38 patients (34%) suffered from anosmia. In the postoperative olfactory function test 89 patients (80%) had a normal sense of smell; 13 patients (12%) showed hyposmia,

Abstract Poor olfaction may be associated with cardiovascular health in older adults, but empirical evidence is limited. We evaluated the association of olfactory status with risk of coronary heart disease (CHD) among 5142 participants free of CHD from the ARIC Neurocognitive Study (75.4±5.1 years, 62.9% female, and 23.9% Black participants). Olfaction was assessed in 2011-2013 using the 12-item Sniffin’ Sticks odor identification test, and defined as good (score 11-12), moderate (9-10), and poor (0-8).

Loss of olfactory function is one of the main symptoms in patients with chronic rhinosinusitis. This prospective, non-randomized interventional study reports five years results of olfaction of patients with chronic rhinosinusitis who underwent endoscopic sinus surgery in conjunction with topical medical treatment. Forty-five patients with chronic rhinosinusitis who underwent endoscopic sinus surgery were evaluated preoperatively, after three months and 34 (76%) of them after five years.

Abstract:

Little is known about the olfactory capabilities of extinct basal (non-neornithine) birds or the evolutionary changes in olfaction that occurred from non-avian theropods through modern birds. Although modern birds are known to have diverse olfactory capabilities, olfaction is generally considered to have declined during avian evolution as visual and vestibular sensory enhancements occurred in association with flight. To test the hypothesis that olfaction diminished through avian evolution, we assessed relative olfactory bulb size, here used as a neuroanatomical proxy for olfactory capabilities

Abstract:

The opacification of the olfactory cleft (OC) has been associated with birhinal orthonasal olfaction in patients with chronic rhinosinusitis (CRS). The aim of this study was to determine the associations between monorhinal and birhinal orthonasal, and retronasal olfaction with radiological markers of the OC in a cohort of patients with CRS. Results were analyzed in a CRS-cohort including 13 patients with nasal polyposis (CRSwNP) and 12 patients with non-eosinophilic CRS (non-eCRS). Monorhinal and birhinal orthonasal olfactory function, and OC-air volume were higher in non-eCRS compared CRSwNP.

Abstract:

Decades before the existence of anything resembling an artificial intelligence system, Alan Turing raised the question of how to test whether machines can think, or, in modern terminology, whether a computer claimed to exhibit intelligence indeed does so. This paper raises the analogous issue for olfaction: how to test the validity of a system claimed to reproduce arbitrary odours artificially, in a way recognizable to humans. Although odour reproduction systems are still far from being viable, the question of how to test candidates thereof is claimed to be interesting and non-trivial, and a n

Dopamine depletion is a major neuropathological feature of Parkinson’s disease (PD); however, 15% of patients with a clinical PD diagnosis have neuroimaging evidence of intact dopaminergic function. Recent work has suggested that patients with SWEDD are at a greater risk of cognitive impairment relative to t
