Assessment of the Prevalence of Olfactory Disorders in Systemic Scleroderma

2019-12-03 23:27:53 | BioPortfolio


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 disease

Assesment of Olfactory Disorders and Performance of a New Olfactory Test in Children With Congenital CMV

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 inve...

Olfactory Dysfunction of Rhinosinusitis

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 loca...

Determinants of Olfactory Dysfunction in Chronic Rhinosinusitis

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 docu...

At-Home Olfactory Training

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 dysf...

Does Olfactory Training Improve Olfaction in a Population With Normal Sense of Smell?

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...

Role of Adult-Born Versus Preexisting Neurons Born at P0 in Olfactory Perception in a Complex Olfactory Environment in Mice.

Olfactory perceptual learning is defined as an improvement in the discrimination of perceptually close odorants after passive exposure to these odorants. In mice, simple olfactory perceptual learning ...

Complex neural representation of odor information in the olfactory bulb.

The most important task of the olfactory system is to generate a precise representation of odor information under different brain and behavioral states. As the first processing stage in the olfactory ...

Characterization of rat glutathione transferases in olfactory epithelium and mucus.

The olfactory epithelium is continuously exposed to exogenous chemicals, including odorants. During the past decade, the enzymes surrounding the olfactory receptors have been shown to make an importan...

Olfactory identification associates with cognitive function and the third ventricle width in patients with relapsing-remitting multiple sclerosis.

Olfactory dysfunction is a known clinical feature of multiple sclerosis (MS). Some studies have shown that odor identification impairment is an essential feature associated with cognitive function in ...

Self-reported mini olfactory questionnaire (Self-MOQ): A simple and useful measurement for the screening of olfactory dysfunction.

Olfactory dysfunction is a common problem. However, too little attention has been paid to questionnaires used to evaluate quantitative olfactory dysfunction. Therefore, the current study aimed to deve...

Medical and Biotech [MESH] Definitions

Set of nerve fibers conducting impulses from olfactory receptors to the cerebral cortex. It includes the OLFACTORY NERVE; OLFACTORY BULB; olfactory tract, olfactory tubercle, anterior perforated substance, and olfactory cortex. The term rhinencephalon is restricted to structures in the CNS receiving fibers from the olfactory bulb.

Neurons in the OLFACTORY EPITHELIUM with proteins (RECEPTORS, ODORANT) that bind, and thus detect, odorants. These neurons send their DENDRITES to the surface of the epithelium with the odorant receptors residing in the apical non-motile cilia. Their unmyelinated AXONS synapse in the OLFACTORY BULB of the BRAIN.

The 1st cranial nerve. The olfactory nerve conveys the sense of smell. It is formed by the axons of OLFACTORY RECEPTOR NEURONS which project from the olfactory epithelium (in the nasal epithelium) to the OLFACTORY BULB.

Ovoid body resting on the cribriform plate of the ethmoid bone where the olfactory nerve terminates. The olfactory bulb contains several types of nerve cells including the mitral cells, on whose dendrites the olfactory nerve synapses, forming the olfactory glomeruli. The accessory olfactory bulb, which receives the projection from the VOMERONASAL ORGAN via the vomeronasal nerve, is also included here.

That portion of the nasal mucosa containing the sensory nerve endings for SMELL, located at the dome of each NASAL CAVITY. The yellow-brownish olfactory epithelium consists of OLFACTORY RECEPTOR NEURONS; brush cells; STEM CELLS; and the associated olfactory glands.
