“…Concerning the effect of smoking on olfaction, literature suggests that smoking has a negative effect on olfactory sensitivity, making smokers less capable to recognize and discriminate flavors and also making them have a lower intensity perception 22 . Furthermore, the negative impact of smoking on olfactory functions is comparable for both active and passive smokers 33 . Chronicity and level of dependence on smoking is proposed to be associated with the rates of alterations in the sense of smell 23 .…”

INTRODUCTION We evaluated the tobacco odor intensity of cigarettes based on a large consumer panel and explored the differences of odor intensity perception based on sex, age and smoking habits. METHODS The perceived intensity of tobacco odor of cigarettes was evaluated using a consumer group method. A consumer panel of 240 volunteers (80 smokers, 80 ex-smokers and 80 non-smokers) was asked to smell eleven unlit cigarettes and then report their tobacco odor intensity in a specific questionnaire. RESULTS All volunteers clearly determined the presence of tobacco odor in all cigarettes. There is a general decrease of the perceived odor intensity with age, for both males and females. Moreover, tobacco odor perceived intensity, among all volunteer groups (smokers, non-smokers, ex-smokers), was higher for females than for males. Non-smokers declared the highest perceived tobacco odor intensities, followed by ex-smokers and smokers, who recorded the lowest perceived odor intensity. Perceived odor intensity decreased with age, with a higher rate for females compared to males, but independently of the smoking habits. CONCLUSIONS Regular and untrained consumers confirmed that a tobacco odor of different intensity can be perceived during the smelling of unlit cigarettes. This perceived intensity depends on sex, age and smoking habits.

“…Factors contributing to age-related olfactory loss include degeneration of olfactory epithelium, conductive loss due to nasal obstruction, and central nervous system disorders 13 . Smoking is also a factor, with passive and active smoking negatively affecting olfaction, particularly olfactory threshold, recognition, and discrimination 14 . Gender is another factor, with women generally having better odor recognition abilities than men.…”

Objectives This study explores how nasal structure and mucosal contractility in CRSsNP patients relate to and potentially affect their olfactory function.. Design and Setting The subjective olfactory function of the patients was assessed using the Sniffin’ Stick test. Patients with an olfactory total score of ≤27 were classified into the olfactory disorder group, while those with an olfactory total score of >27 were classified into the normal olfactory function group. Participants Patients diagnosed with Chronic Rhinosinusitis without Nasal Polyps (CRSsNP) at our hospital’s Department of Otorhinolaryngology-Head and Neck Surgery. Main outcome measures Acoustic Rhinometry (AR) was employed to assess the patients’ nasal cavity structure and nasal mucosal contractility. Results No significant differences were found in gender, age, smoking history, and nasal function indicators between the normal olfaction and olfactory disorder groups (P > 0.05). After controlling for age, olfaction was negatively correlated with nasal mucosal contractility (ΔNV2-5). In the normal olfaction group, olfactory threshold was positively correlated with ΔNV2-5 (P < 0.01), while no significant correlation was observed in the olfactory disorder group. Multiple linear regression analysis revealed that age and NV2-5 were negatively correlated with total olfactory score. Conclusions The reduction of olfaction in CRSsNP patients does not affect the contractility and relaxation functions of the nasal mucosa.As the nasal cavity volume increases, the sensitivity of olfaction in CRSsNP patients actually decreases.The relative stability of the nasal mucosa in CRSsNP patients allows their olfactory cognitive ability to reach its optimal state.

Introduction.Many neurodegenerative disorders are associated with olfactory dysfunction (OD), but little is known about OD in Wilson's Disease (WD). We evaluated olfactory function in patients with WD.Material and methods. OD was examined in 68 patients with WD and 70 sex-and age-matched healthy controls using subjective testing with 'Sniffin Sticks' . Threshold discrimination identification (TDI) score and its three components (odour detection threshold, discrimination, and identification) were assessed.Results. Compared to controls, patients with WD had a significantly weaker sense of smell in terms of TDI (p < 0.01), odour discrimination (p < 0.01), and identification (p < 0.01), but not in terms of odour detection threshold (p = 0.27). Patients with predominantly neurological symptoms were characterised by greater OD by TDI (p < 0.01), odour detection threshold (p = 0.01), and discrimination (p = 0.03). The presence of pathological lesions (p = 0.04) in brain magnetic resonance imaging and generalised brain atrophy (p = 0.02) predisposed to worse TDI.In the WD group, weak inverse correlations between age and TDI score (r = -0.27), odour detection threshold (r = -0.3), and discrimination (r = -0.3) were found. Male gender was a risk factor for abnormal TDI in both WD and controls (both p = 0.02). Conclusions.Patients with WD, particularly older individuals, more frequently had OD than healthy volunteers. Predominantly neurological symptoms, and the presence of typical brain MRI changes, predisposed patients with WD to smell disorders.
