Sinusitis. Definition. Sinusitis is inflammation of the sinuses, which are air- filled cavities in the skull. The etiology can be infectious (bacterial, viral, or fungal) or noninfectious (allergic) triggers. This inflammation leads to blockade of the normal sinus drainage pathways (sinus ostia), which in turn leads to mucus retention, hypoxia, decreased mucociliary clearance, and predisposition to bacterial growth. Sinusitis can be divided into the following categories: 1. Acute sinusitis, defined as symptoms of less than 4 weeks’ duration (Fig.
Subacute sinusitis, defined as symptoms of 4 to 8 weeks’ duration; Chronic sinusitis, defined as symptoms lasting longer than 8 weeks (Fig. Recurrent acute sinusitis, often defined as three or more episodes per year, with each episode lasting less than 2 weeks. Back to Top. Prevalence. The prevalence of acute sinusitis is on the rise, based on data from the National Ambulatory Medical Care Survey (from 0. In 2. 00. 1, sinusitis represented 1. U. S.

When sinusitis is considered together with commonly associated comorbid conditions such as allergic rhinitis, asthma, and chronic bronchitis, exacerbation of these diseases affects more than 9. Americans. 5 The socioeconomic impact of this translates to more than $5. Back to Top. Pathophysiology. The most common cause of acute sinusitis is an upper respiratory tract infection (URTI) of viral origin. The viral infection can lead to inflammation of the sinuses that usually resolves without treatment in less than 1.
Sinusitis Insight into sinus problems in adults and children. How are sinusitis symptoms different than a cold or allergy? When does acute sinusitis become chronic?
Symptoms and Complications. Sinusitis has symptoms very different from a cold or the flu. The main symptoms are face pain or pressure, congestion, nasal discharge or. Learn about sinus infection, or sinusitis signs and symptoms like nasal congestion, post-nasal drip, pain in the sinus area, fever, and cough. Are sinus infections.
If symptoms worsen after 3 to 5 days or persist for longer than 1. The inflammation can predispose to the development of acute sinusitis by causing sinus ostial blockage. Although inflammation in any of the sinuses can lead to blockade of the sinus ostia, the most commonly involved sinuses in both acute and chronic sinusitis are the maxillary and the anterior ethmoid sinuses. The anterior ethmoid, frontal, and maxillary sinuses drain into the middle meatus, creating an anatomic area known as the ostiomeatal complex (Fig. The nasal mucosa responds to the virus by producing mucus and recruiting mediators of inflammation, such as white blood cells, to the lining of the nose, which cause congestion and swelling of the nasal passages.
The resultant sinus cavity hypoxia and mucus retention cause the cilia—which move mucus and debris from the nose—to function less efficiently, creating an environment for bacterial growth. If the acute sinusitis does not resolve, chronic sinusitis can develop from mucus retention, hypoxia, and blockade of the ostia.
This promotes mucosal hyperplasia, continued recruitment of inflammatory infiltrates, and the potential development of nasal polyps. However, other factors can predispose to sinusitis (Box 1). Box 1: Conditions that Predispose to Sinusitis. Allergic rhinitis. Nonallergic rhinitis.

The Cleveland Clinic Foundation. When bacterial growth occurs in acute sinusitis, the most common organisms include Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis.
In chronic sinusitis, these organisms, plus Staphylococcus aureus, coagulase- negative Staphylococcus species, and anaerobic bacteria, are the most likely involved organisms. Organisms isolated from patients with chronic sinusitis increasingly are showing antibiotic resistance.
In fact, penicillin resistance rates for S. United States. 1. These resistant organisms commonly occur in patients who have received two or more recent courses of antibiotics.
A distinct entity, allergic fungal sinusitis (AFS), occurs in immunocompetent patients and results from an immunologic reaction to fungi that colonize the sinuses. Most people tolerate exposure to mold spores in the air because they are ubiquitous in our environment. However, people with AFS develop a hypersensitivity reaction involving an intense eosinophilic inflammatory response to the fungus that has colonized the sinuses. Common fungi associated with this syndrome include Bipolaris specifera and Aspergillus, Curvularia, and Fusarium species. This is an allergic noninvasive response to the fungus that should be distinguished from invasive fungal sinusitis, which is more common in diabetic and immunocompromised patients.

When all studies on adults are analyzed the most common cause is post nasal drip. PND), mucus dripping from the nose and/or sinuses into the back of the throat. PND FROM RHINITIS & /OR SINUSITIS IS THE MOST COMMON CAUSE OF CHRONIC COUGH IN. ADULTS. It is not asthma or acid reflux, or pneumonia, or cancer. Also, chronic cough is virtually never a psychological problem.
Various studies show anywhere from 3. In my experience, the higher number for PND (8. The number two cause in various studies. The higher numbers add up to. In these and other studies, more than one cause of chronic cough was.
Given that multiple causes are often present. What about in children? According to Dr. Irwin, the most common cause of chronic cough in children is. PND and then GERD.
See. Irwin RS. Silencing Chronic Cough. Hospital Practice, January 1. Is GERD (gastro- esophageal reflux disease) a common cause of chronic cough? No. In fact, GERD is probably the most over- diagnosed cause of. Note: In Great Britain and other countries the condition. GORD, because it is spelled gastro- oesophageal reflux disease.).

S. The majority of patients with chronic cough have rhinosinusitis. What is the most common cause of rhinosinusitis? By far the most common cause is the same as that for the common cold. Most viral infections, especially the common cold, are not treated. However, bacterial infections are treated with antibiotics.
If. the symptoms are confined to the nasal passages, and are typical of a common cold, and. However, if the symptoms suggest. In truth, doctors can't distinguish. For this. reason virtually all patients diagnosed with 'sinusitis' (acute or chronic). Why is treatment of rhinosinsitis so variable?

It is common for patients with chronic cough to be referred to another physician.
Allergists also get a lot of referrals for this problem. Allergists and. pulmonologists refer cough patients as well, especially to ENT physicians.
And ENT physicians who cannot help a problem through surgical means. The result is that patients with chronic cough of more than. The root problem is that chronic cough can be difficult to both diagnose. What is the relationship of rhinosinusitis and asthma? In a word, complex.
Asthma is a disease manifested by excessive mucus production in the lungs. In fact. most asthmatics also have mucus in their sinuses. Usually this is from a viral infection. Thus patients 'with asthma' will commonly also have inflammation of their sinuses. On the other hand, rhinitis and sinusitis can be the triggers of asthma. That is. patients without any asthma history can develop asthma AS A RESULT OF. Simplistically, this seems to occur from.
The. actual mechanism, however, is unknown.
Allergies or Chronic Sinusitis? Most Get it Wrong, Go Untreated. The pollen count is through the roof and once again, you have a stuffy nose, sinus pain, fatigue and reduced sense of smell and taste.
Oh great, another bad allergy season, you think. And you'd be wrong. These are the hallmarks of a sinus infection, not allergies, though most allergy patients can't tell the difference, according to a recent survey by the Asthma and Allergy Foundation of America. In an online survey of more than 6.
Despite the fact that 7. This study highlights how often people diagnose themselves. We're human. It's a natural response to go online and come up with our own diagnosis, but 1. I get patients coming in convinced they have X, when really they have Y," says Dr. Stacey Silvers, an ear, nose, and throat doctor at Beth Israel Hospital in New York City. For years, New Yorker Dawn Burley, 2. But allergy medication didn't lessen her symptoms, and she hated treating the pain of her migraines without knowing their cause.
She had such severe pressure and pain around her eyes that she would become sensitive to light and had difficulty sleeping. It was really ruining my life. I'd have so many days where I could barely function," she says. It wasn't until she saw Silvers that anyone put her symptoms together and realized she had sinus problems. Though she had been diagnosed with acute sinus infections in the past, no doctor had recognized that Burley had chronic sinusitis because of the way her sinuses were formed.
After undergoing a minimally- invasive, in- office procedure in which a balloon is inflated to open her sinus passageways - - a more extensive treatment than most require - - Burley says she could breathe easier, sleep sounder and had more stamina. I didn't even realize that these things could get better," Burley says. This is not uncommon of those with untreated sinus or allergy problems, Silvers says. I've had patients tell me they didn't know it wasn't normal that their nose was always clogged at night. They didn't realize that most people can breathe out of both sides of their nose. People get used to these things, and they don't think it's abnormal or treatable," she says. Sinus Infection vs.
Allergies - - How Do You Know? Thirty- five million Americans suffer from nasal allergies and 7 million suffer from chronic sinus infections, yet most people can't tell the difference between these two conditions.
There is abundant confusion between cold, sinus and allergy symptoms," says Dr. Clifford Bassett, medical director of the Allergy and Asthma Care of New York.
This means that often these conditions get mistreated or go untreated, which can lead to "chronic nasal congestion and associated symptoms" that can affect quality of life as well as daytime performance, he says. Westlake Mews For Adults 55 Plus. Here's a breakdown of which symptoms belong to which ailments.
The Common Cold - - "Cold and allergy can present similarly," says Silvers, so the defining difference is the length: If your congested nose and breathing difficulty last longer than seven to 1. Most likely, it's allergies, and needs to be treated with an antihistamine, not a decongestant. Seasonal Allergies - - If your sinus congestion is accompanied by watery or itchy eyes and it tends to last several weeks, it's may be allergies, says Silvers. The problem is, many often treat their allergies like a cold, with over- the- counter decongestants, which will work in the short run but are not advisable. When someone is taking a daytime decongestant every day and a nighttime one to sleep, for weeks and weeks, this is not good," she says. Especially when their allergy might be due to an environmental trigger, such as a feather pillow, that could be easily eliminated. Sinusitis or Chronic Sinusitis - - With sinusitis, the nasal passageways become inflamed and the liter or more of mucus created every day by your body gets backed up in the sinuses.
This is when you get patients complaining of headache, pressure or pain in their face and chronic fatigue," Silvers says. A headful of mucus is an exhausted head, one that's hard to lift off the pillow and patients can be irritable and fatigued on most days," says Silvers. If you suffer from facial tenderness, pressure or pain, headache behind the eyes and forehead, or loss of taste or smell and fatigue, you may have sinusitis. If you experience this three or more times a year, you may have chronic sinusitis, like Burley, and should consult with your physician or an ear, nose and throat specialist. What most people don't know, Silvers says, is that you can have sinusitis without having a runny or stuffy nose or difficulty breathing, because the mucus is congested further back in the sinuses. If you suffer from any of the above symptoms and they do not resolve within a week or so (and hence are unlikely to be a cold or flu), you should consider seeing your physician, who may refer you to an allergist or an ear, nose and throat specialist.
