About This Presentation

Description : Check out this medical PowerPoint presentation titled "Nonallergic Rhinitis and Acute and Chronic Sinusitis" by Marilene B. Wang, MD, FACS.

This medical PowerPoint presentation is about nonallergic rhinitis and sinusitis, two different conditions that can affect the nasal passages and sinuses.

Nonallergic rhinitis refers to a condition where the nasal passages become inflamed and irritated, causing symptoms such as runny nose, stuffy nose, postnasal drip, and sneezing. This condition is not caused by an allergic reaction, but rather by irritants such as smoke, pollution, strong odors, or changes in temperature and humidity.

Sinusitis, on the other hand, refers to inflammation of the sinuses, which are air-filled spaces located in the bones of the face and skull. Acute sinusitis is a short-term condition that is typically caused by a bacterial or viral infection. Symptoms include facial pain, headache, nasal congestion, and fever. Chronic sinusitis is a long-term condition that can last for months or even years. It is usually caused by inflammation rather than infection and is associated with symptoms such as nasal congestion, postnasal drip, facial pain, and decreased sense of smell.

The treatment for nonallergic rhinitis and sinusitis varies depending on the cause and severity of the condition. Nonallergic rhinitis can be managed with over-the-counter nasal decongestants, antihistamines, and saline nasal sprays. Avoiding irritants that trigger symptoms can also help. Acute sinusitis is usually treated with antibiotics, nasal corticosteroids, and decongestants. Chronic sinusitis may require a more comprehensive treatment plan, including prolonged courses of antibiotics, nasal corticosteroids, and in some cases, surgery.

It is important to see a healthcare provider if you experience symptoms of nonallergic rhinitis or sinusitis. Your provider can help determine the underlying cause of your symptoms and develop a treatment plan that is tailored to your needs.

Slide 1-

Nonallergic Rhinitis (Ch.46)Acute and Chronic Sinusitis (Ch. 47) Marilene B. Wang, MD, FACS Professor UCLA Department of Head Neck Surgery Chief of Otolaryngology VA Greater Los Angeles Healthcare System
Slide 2-

1. Nonallergic rhinitis Is more common in males Incidence increases with age May occur in conjunction with allergic rhinitis B and c All of the above
Slide 3-

2. Innervation of the nasal mucosa Parasympathetic nerves are the primary component of the efferent nasal reflex arc. Parasympathetic nerves release vasoactive intestinal peptide Parasympathetic nerves cause nasal decongestion C fibers are efferent nerves that react to pain, changes in temperature, osmolarity and irritants. All of the above
Slide 4-

3. Nasal provocation testing Can differentiate between allergic and non-allergic rhinitis Done with histamine is specifically for allergic rhinitis Done with capsaicin is specifically for nonallergic rhinitis Done with histamine causes decreased vascular permeability, sneezing, and nasal obstruction Done with methacholine leads to increased rhinorhea
Slide 5-

4. Nonallergic rhinitis with eosinophilia Occurs in response to common allergens such as dust, pollen, mold Symptoms are exacerbated by weather changes Occurs in over half of patients with nonallergic rhinitis Involves mast cells and Ig-A positive cells in the nasal mucosa Does not occur with nasal polyps
Slide 6-

5. Rhinitis of pregnancy Occurs more frequently in pregnant women who smoke Affects the majority of pregnant women Occurs in response to estrogen-induced vascular smooth muscle relaxation Severity of symptoms parallels blood progesterone levels All of the above
Slide 7-

6. Medication-induced rhinitis can be found from use of the following medications: Aspirin Oral contraceptives Amitryptiline Hydralazine All of the above
Slide 8-

7. Atrophic rhinitis Is most commonly associated with infection from Klebsiella pneumoniae Can occur after aggressive nasal surgery Is most common in young adults Results in changes in nasal mucosa from squamous epithelium to ciliated respiratory epithelium Can be treated effectively with antibiotics
Slide 9-

8. Idiopathic rhinitis Is also known as vasomotor rhinitis Occurs rarely Involves autonomic nervous system dysfunction A and c All of the above
Slide 10-

9. Diagnosing nonallergic rhinitis Requires a thorough history Requires acoustic rhinomatry Requires a sinus CT scan All of the above None of the above
Slide 11-

10. Treatment of nonallergic rhinitis a. May include nasal steroids, antihistamines, and anticholinergics b. Septoplasty and/or turbinate reduction may be of benefit c. Vidian neurectomy can provide relief of rhinorrhea d. A and c e. All of the above

Major Healthcare Problem Problem One of most common healthcare problems in U.S. Over 31 million Americans affected annually 18-22 million physician office visits annually
Slide 14-

Definition of rhinosinusitis Group of disorders characterized by inflammation of the mucosa of the nose and paranasal sinuses Acute, subacute, chronic

Slide 16-

Paranasal Sinus Function Lining – pseudostratified ciliated columnar epithelium Mucous and serosanguinous glands Parasympathetic and sympathetic innervation
Slide 17-

Paranasal Sinus Function Mucous blanket renewed every 10-15 minutes Warm and humidify air Secrete immunoglobulins, interferons, inflammatory cells
Slide 18-

Paranasal Sinus Function Cilia beat 10-15 times/second Cilia function varies with environment, allergies, etc. Mucociliary system—cleanse sinus, immunoprotective Move mucous to natural ostia of sinuses
