Filter by:The study will be a randomized controlled trial, involving patients with hyposmia/anosmia of onset immediately after an upper respiratory viral illness, assigned to three distinct study arms. Nasal irrigations will be prescribed to all three groups (BID). In addition, one arm will receive a paper hand-out about post-viral anosmia with instructions to smell common household items (current care) and act as a control group. The second group will receive an essential oil retraining kit, whereas the third group will receive the same olfactory training kit and a prescription to use budesonide with the nasal irrigations. Olfactory scores will be tested at the enrollment, 3 months and at 6 months.
Cancer patients are at high risk of undernutrition, which is generally more pronounced for solid tumours (upper digestive tract, Ear Nose and Throat (ENT), bronchial tubes). This undernutrition leads to major weight loss and cachexia, and may represent the first sign of a call for a diagnosis of cancer. Cancer-related undernutrition is multi-factorial origins and has multiple consequences. Chemotherapy treatments can induce various adverse effects in patients, including sensory disturbances at the beginning of treatment in addition to disturbances that may already be present before any treatment. The alteration of taste and odour, observed in 86% of patients, can induce a change in food preferences, promote the development of aversions, and therefore, lead to a significant reduction in the pleasure of eating. Loss of appetite, decreased food intake and the development of aversions to certain foods are situations experienced by a large proportion of patients treated with chemotherapy. The assessment of taste disorders in patients treated with chemotherapy is established through the use of questionnaires, interviews and taste tests. Changes in the perception and identification of salty, sweet, bitter and sour flavours are common in patients treated with chemotherapy. As regards food products, patients report developing olfactory hypersensitivity mainly for food of animal origin, in particular for odours of fish, frying, cheese and eggs. The CANUT project aims to study the effect of pathology and chemotherapy on gustatory and olfactory mechanisms, and in particular on interindividual differences in the perception and appreciation of food. In order to monitor the evolution of patients' eating habits over time, the diet-related quality of life questionnaire (CANUT-QVA) was constructed from items selected from the Well-being related to Food questionnaire (WELLBFQ) after eliminating questions that were too general or expressed in terms of importance to use perception-related responses as a priority. After this part, an evaluation of the 9 dimensions of the CANUT-QVA questionnaire will be performed.
A prospective, controlled, single blinded study was planned. 20 patients with Acromegaly (Acromegaly Group) and 20 healthy subjects (Control Group) were planned to include in the study. Connecticut Chemosensory Clinical Research Center (CCCRC) test was applied to evaluate olfactory functions. Olfactory bulb(OB) volumes were measured with a 1.5 T General Electric Signa Excite MRI scanner.
This study evaluates the efficacy and safety of nasal theophylline irrigation in treating smell loss related to a viral respiratory infection. Half the participants will undergo nasal theophylline irrigation treatment while the other half will undergo placebo nasal irrigation with saline alone. All participants will have their sense of smell tested before and after 6 weeks of treatment. All participants will also be regularly asked about any potential side effects related to treatment. In addition, the first 10 participants will have their blood drawn to measure their theophylline level after 1 week of starting treatment to ensure it is not abnormally elevated.
The purpose of this study is to determine the impact of a twice daily at-home olfactory training program with a twenty scent, essential oil-based smell test in patients with olfactory dysfunction.
About One to 2 percent of the North American population below the age of 65 years experience olfactory loss to a significant degree. It can result from advanced age, Post-infestious/inflammatory disorders, Obstructive disorders (e.g. nasal polyposis, tumors), posttraumatic (head trauma) and neurodegenerative disorders. Only a few studies have shown benefits of specific therapy for olfactory loss. Vitamin has shown promise from both animal and human studies. However, none has studied the benefits of topical application of vitamin A. This study will be the first to examine this effect.
The purpose of this research study is to examine the efficacy of a 12-week smell training intervention for participants with olfactory dysfunction following an infection of the upper respiratory tract.
The purpose of this study is to determine the normal distribution of nasal tissue cathelicidin antimicrobial peptides (cAMP) levels in subjects with normal smell and subjects with smell dysfunction. The investigators will also look at the effect of nasal saline irrigation on olfaction and cAMP levels and if nasal irrigation is capable of harvesting olfactory cilia. The investigators hypothesize that nasal saline will have no effect on olfaction and will be inadequate to harvest olfactory cilia.
