Prospective monocentric study of patients with systemic sclerosis disease. The primary outcome is to define the prevalence of olfactory disorders (hyposmia and anosmia) in systemic sclerosis disease. The secondary outcomes are: - To assess the correlation of olfaction disorders with clinical and biological and factors related to systemic sclerosis patients. - To estimate the frequency of sinonasal disorders in patients with systemic sclerosis dis...
CMV lesions were found in the olfactory system of children with congenital CMV infection but no study has hitherto examined the impact of congenital CMV infection on olfaction. So the investigators propose in this study to assess the proportion of children with olfactory deficits among children with congenital CMV infection. Second this study will also evaluate performances of a new olfactory test, based on discrimination of binary odorant mixtures.
During the past three decades, researchers have paid particular attention to the study of olfactory disorders in depression. Recent studies have shown that depression is characterized by a change in olfactory and emotional perception resulting in a decrease of the perception of positive stimuli (odors and facial expressions) and an increase in perception of negative stimuli (odors). Moreover, it has also been shown in healthy subjects that the presence of minor depressive sympt...
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 s...
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.
For twenty years research has shown a strong link between olfactory disorders and Alzheimer's disease. The focus is on the very early alteration of the olfaction which acts as a harbinger of the disease since it is detectable in its asymptomatic phase. In addition, olfactory involvement is a precursor to the transformation of mild cognitive impairment into MA. Indeed the anatomical structures the first lesions are located in the transentorhinal region of the temporal lobe and e...
Analyze the behavioral response of patients with disorders of consciousness through olfactory stimulation, compare the response of olfactory stimulation in patients with different consciousness, and analyze the impact of olfactory stimulation on diagnosis; After the first, third, and sixth months of initial enrollment, the recovery of prognosis was tracked by the Coma Recovery Scale-Revision (CRS-R).
Olfactory dysfunction is a cardinal symptom of chronic rhinosinusitis, a disease which affects 12.5% of the adult population across all racial and ethnic groups. Previous research has documented olfactory deficit in 68% of patients with chronic rhinosinusitis and 20% with complete anosmia, suggesting that olfactory dysfunction affects over 25 million individuals in the United States with chronic rhinosinusitis. This proposed investigation will be used to predict olfactory outco...
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.
To obtain olfactory bulbs from brain stem dead patients who undergo organ donation. Aims: 1. Optimisation of olfactory bulb collection and olfactory ensheathing cell culture and storage. 2. Study of the effects of patient diagnosis, age, cause of death and co-morbidities on cell survival and regenerative function. 3. In future studies, the olfactory ensheathing cells may be injected into patients with spinal cord injuries.
Awareness of the sense of smell in the western population has been low. Most people do not think about the consequences of absence of smell (anosmia). Reduction in sense of smell (hyposmia) can influence everyday life. In situations of stress anosmia can be life threatening for example when there is a fire. Cooks may lose their job. Not being able to enjoy food and drink interferes with quality of life. The causes of olfactory dysfunction (OD) vary. Most often OD is associated ...
The objective of our study is to determine which factors affect willingness to participate in gynecologic oncology clinical trials. Women with a diagnosis of gynecologic malignancy will be approached to complete a survey assessing willingness to participate in clinical trials. The validated Attitudes and Randomized Trials Questionnaire (ARTQ) will be used to assess willingness to participate.
The aim of the study is to see whether patients with chronic smell impairment after brain injury benefit from a treatment that consists of corticosteroids, and then olfactory training in 3 months.
The study aimed to determine the emotional reactivity of depressed patients to visual and olfactory stimuli in comparison with healthy volunteers.
Signal processing in the olfactory neuron could be influenced by inhibition of enzymes like phosphodiesterase. Pentoxifylline is a unspecific phosphodiesterase inhibitor. The hypothesis is that pentoxifylline could lead to increased sensitivity to odors.
Nasal polyposis (NP) is a disease affecting 4% of the population. This disease is frequently accompanied by olfactory disorders (41%-84% of patients) that affect patients' quality of life. The aim of this study is to show brain activity differences in olfactory areas before and after surgery in each patient and between patient groups (normosmic, hyposmic and anosmic one) using functional Magnetic Resonance Imaging (fMRI). Brain activity will be measured by the intensity ...
To study the correlation of POCD with olfactory function. To explore whether enhanced olfactory stimuli can reduce the risk of POCD as a preventive strategy.
In this project the investigators aim to evaluate olfactory and non-olfactory function in patients within the first 24h following a mild traumatic brain injury (acute mTBI) and compare their results to a group of age and sex matched control patients suffering from an orthopedic injury 24h prior to testing. The investigators then aim to follow them up 1 year after the trauma
The purpose of this research is to improve understanding of the molecular and functional properties of the human olfactory system. The specific aims are: - to determine the location of AC3 and Golf proteins in the human olfactory epithelium from freshly harvested nasal/sinus tissue of surgical patients - to perform objective functional studies on fresh human nasal/sinus tissue using an electro-olfactogram (EOG) whic measures the electrical activity of o...
The primary aim of the study is to test the feasibility and efficacy of, a manual based, Internet-delivered, cognitive behaviour therapy (CBT) for Olfactory Reference Syndrome (ORS). The secondary aim is to investigate smell sensitivity and body odor in ORS-patients.
In the literature the use of olfactory dimension in the treatment of anorexia has not been verified experimentally. The investigator hypothesize that the therapeutic use of a dietary nature olfactory stimuli in anorexia nervosa promotes food recovery. The team propose a prospective study over a period of 12 months in which we use the Body Mass Index (BMI) as the primary endpoint of the state of anorexia nervosa patients.
The purpose of this study is to pilot the "ToPIC" tool, a communication tool to facilitate clinical trial decision making conversations between oncologists and patients.
This within-subject crossover experiment uses one night of acute sleep restriction (4h) vs normal sleep (8h) to study state-dependent changes in olfactory processing. Odor-evoked blood oxygen level dependent (BOLD) responses will be measured in olfactory brain regions using functional magnetic resonance imaging (fMRI). Food intake will be measured at a buffet.
The purpose of this experimental therapy is to evaluate the safety and efficacy of transplantation of autologous olfactory ensheathing cells (OECs) and olfactory nerve fibroblasts (ONFs) obtained from the olfactory bulb with simultaneous reconstruction of the posttraumatic spinal cord gap with peripheral nerve grafts, in patients with chronic complete spinal cord injury. The treatment will be performed in two patients that have sustained an anatomically complete spinal cord tra...
Glaucoma is one of the leading causes of blindness worldwide. The key feature of glaucoma is damage to the optic nerve head with loss of retinal ganglion cells and local tissue remodeling. Neuronal cell death in glaucoma occurs by apoptotic mechanisms1. Apoptosis of neurons also plays a major role in neurodegenerative diseases, such as Alzheimer's or Parkinson's disease. An association between glaucoma and these disorders has been described 2-4. Furthermore, it has been reporte...
