Summary
Post-infectious olfactory dysfunction (PIOD) management focuses on olfactory training as the primary treatment. Systemic corticosteroids are not recommended due to insufficient evidence for treating PIOD.
Area of Science:
- Neurology
- Otolaryngology
- Infectious Diseases
Background:
- Post-infectious olfactory dysfunction (PIOD) is a common sequela of viral infections, including COVID-19.
- Persistent PIOD is associated with reduced frontal lobe perfusion.
Purpose of the Study:
- To review current understanding of PIOD.
- To establish a consensus on evidence-based management strategies for PIOD.
Main Methods:
- Critical review of available management options for PIOD.
- Evidence-based approach to consensus building.
Main Results:
- Olfactory training is identified as the first-line management for PIOD.
- Systemic corticosteroids lack strong evidence for PIOD treatment and are not recommended.
Conclusions:
- Olfactory training is the most recommended management for PIOD.
- Further research is needed to clarify the role of other interventions.

01:03Olfactory Receptors: Location and Structure
9.4K
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...

01:20Physiology of Smell and Olfactory Pathway
9.2K
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.

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.

Managing Chronic Obstructive Pulmonary Disease (COPD) involves a multifaceted approach to reduce symptoms, prevent exacerbations, improve overall health status, and slow disease progression. Key strategies include lifestyle modifications, pharmacotherapy, supportive therapies, and, in some cases, surgery. Here is an overview of the primary COPD management strategies:

Chronic obstructive pulmonary isease (COPD) involves a group of progressive lung disorders characterized by persistent airflow limitation and chronic respiratory symptoms. Asthma-COPD Overlap Syndrome (ACOS), encompassing features of both asthma and Chronic obstructive pulmonary disease (COPD), is a group of progressive lung disorders that includes chronic bronchitis, emphysema, and refractory (non-reversible) asthma. ACOS leads to complex clinical presentations that combine the inflammatory...
