There has been some renewed interest in current situations disorders of olfaction. Decreased sense smell can lead to significant impairment quality life, including taste disturbance and loss pleasure from eating with resulting changes weight difficulty avoiding health risks such as spoiled food or leaking natural gas. When validated identification threshold tests are used, its reveal quite a hi...

BACKGROUND Olfaction dysfunction is linked to neurodegenerative diseases, therefore the evaluation of this function is becoming important AIM To evaluate olfaction in healthy participants. MATERIAL AND METHODS We evaluated 44 healthy males and 55 females, aged 21 to 89 years with the Sniffing Sticks battery to determine normal values in Chilean population. During the test, participants must...

BACKGROUND Although combined oral and nasal steroid therapy is widely used in nasal polyposis, a subset of patients show an unfavorable therapeutic outcome. This study aimed to evaluate whether oral prednisolone produces any additive effects on subsequent nasal steroid therapy and to evaluate if any clinical variables can predict therapeutic outcome. METHODS Using a 3:2 randomization ratio, ...

Olfactory involvement is well recognized in patients with Parkinson's disease (PD). The purpose of this study was to examine smell function quantitatively, using different types and concentrations of odorants in PD patients. We aimed to elucidate whether a specific odor can affect the severity and duration of PD patients. A total of 89 nondemented PD patients and 20 age-matched controls partici...

The prefrontal (PFC) and orbitofrontal cortex (OFC) appear to be associated with both executive functions and olfaction. However, there is little data relating olfactory processing and executive functions in humans. The present study aimed at exploring the role of olfaction on executive functioning, making a distinction between primary and more cognitive aspects of olfaction. Three executive ta...

In order to relieve the symptoms of nasal obstruction in patients with inferior turbinate hypertrophy, various surgical methods have been used. Aim of this study was to compare post-operative outcome between radiofrequency and microdebrider-assisted partial turbinoplasty. A prospective study was performed in 268 patients with nasal obstruction and hypertrophied turbinate mucosa refractory to me...
