Summary
Olfactory function is impaired in mastocytosis patients, with decreased odor detection, discrimination, and identification. This impairment correlates negatively with serum tryptase levels, suggesting it
Area of Science:
- Neurology
- Otorhinolaryngology
- Hematology
Background:
- Mastocytosis is characterized by abnormal mast cell accumulation.
- Olfactory function data in mastocytosis patients is currently unavailable.
Purpose of the Study:
- To assess olfactory function (odor threshold, discrimination, identification) in mastocytosis patients compared to healthy controls.
- To correlate olfactory function with mastocytosis clinical symptoms.
Main Methods:
- Eighty-one participants (41 mastocytosis patients, 40 healthy controls) were enrolled.
- Olfactory function was evaluated using the "Sniffin' Sticks" test.
- Tests included odor detection threshold (OT), odor discrimination (OD), and odor identification (OI).
Main Results:
- Mastocytosis patients exhibited significantly reduced total olfactory function (Threshold-Discrimination-Identification [TDI] score), OT, OD, and OI compared to controls.
- A negative correlation was found between TDI score and serum tryptase concentration.
- No correlation was observed between disease duration and olfactory function measures.
Conclusions:
- Olfactory function is impaired in mastocytosis patients.
- A negative correlation exists between TDI score and serum tryptase levels.
- Olfactory dysfunction is a potential clinical manifestation contributing to the disease burden.

Olfactory Receptors: Location and Structure
10.8K
The process of olfaction, also known as the sense of smell, is a sophisticated chemical response system. The specialized sensory neurons that facilitate this process, known as olfactory receptor neurons, are situated in an upper segment of the nasal cavity, known as the olfactory epithelium. Olfactory sensory neurons are bipolar, with their dendrites extending from the epithelium's apex into the mucus that lines the nasal cavity. Airborne molecules, when inhaled, traverse the olfactory...

Olfaction

The sense of smell is achieved through the activities of the olfactory system. It starts when an airborne odorant enters the nasal cavity and reaches olfactory epithelium (OE). The OE is protected by a thin layer of mucus, which also serves the purpose of dissolving more complex compounds into simpler chemical odorants. The size of the OE and the density of sensory neurons varies among species; in humans, the OE is only about 9-10 cm2.

Physiology of Smell and Olfactory Pathway
11.5K
Humans detect odors with the help of specialized cells located in the upper part of the nasal cavity, called olfactory receptor neurons (ORNs). ORNs possess hair-like structures called cilia, which are receptive to sensations from the inhaled air. When an odorant molecule binds to a specific receptor on the cell of the cilia, it leads to a series of events that ultimately cause the ORN to send electrical signals to the olfactory bulb in the brain through the olfactory nerves.

Taste Buds and Receptors

Gustation, or the sense of taste, is intrinsically linked to the anatomical structures located on the tongue. This organ's surface, along with the entirety of the oral cavity, is adorned with stratified squamous epithelium. Evident on the tongue are elevated structures known as papillae (singular = papilla), which house the mechanisms for the transduction of gustatory stimuli. Four distinct types of papillae exist, each identified by their unique morphological attributes: the circumvallate,...
