Chronic sinusitis can be a miserable condition that significantly impairs your quality of life.It may or may not be as a result of infection, from bacterial, fungal, viral, allergic or autoimmune issues. Viruses or bacteria - or a combination of both - can cause sinusitis.Newer classifications of sinusitis refer to it as rhinosinusitis, taking into account the thought that inflammation of the sinuses cannot occur without some inflammation of the nose as well (rhinitis).
Due to the unique nature of sinus difficulties, many sinus sufferers get frustrated by failed attempts to end their symptoms. If you have chronic sinusitis, you may have difficulty breathing through the nose, experience frequent headaches and tenderness in the face or aching behind the eyes. You may also have frequent yellow or greenish discharge from your nose or drainage down the back of your throat.Because the symptoms of chronic sinusitis can resemble those of colds or allergies, chronic sinusitis can be difficult to diagnose.
Rhinosinusitis is one of the most common reasons for an office visit. However, studies indicate that it is not always accurately diagnosed and that adequate trials of antibiotic therapy may not occur for bacterial rhinosinusitis. Rhinosinusitis can be classified into three groups ; acute, chronic and recurrent acute. Hemophilus influenzae, Streptococcus pneumoniae and Moraxella catarrhalis were the commonest pathogens detected in 80% of the cases.
It can be particularly difficult to identify sinusitis in children. If your child or you have frequent sinus infections, learn what signs to watch for, and begin home treatment immediately.Symptoms of chronic sinusitis are often vague and may not respond well to treatment. It may take time and patience to find a successful treatment.Rhinosinusitis in children is a multifactorial disease.CT scanning with staging of sinus pathology is crucial for detecting mucosal inflammatory changes, besides morphological variations and anatomical study of the ostiomeatal complex.This self-study activity provides practical guidance to primary care clinicians concerning key aspects of care for rhinosinusitis including:
*Diagnosing acute bacterial rhinosinusitis
*Treatment with antibiotics and ancillary therapies
*Effective radiological imaging
*Appropriate subspecialist consultation
U.S. doctors are consistently overprescribing antibiotics for sinus infections, a new study finds, but even the physician who led the research doesn't see how the problem can be eliminated.
That's because when it comes to treatments for sinus trouble, antibiotics are the best of a bad lot, said Dr. Donald A. Leopold, chairman of the department of otolaryngology at the University of Nebraska Medical Center.
"We as physicians don't have very good medications for chronic rhinosinusitis," he said. "The only other drugs in contention are topical steroids, and they are not great. As a group I suggest we are frustrated at not having good drugs. It would be great if we had better medications for this chronic inflammation."
Another factor is what patients demand, Leopold said. "Many patients call up and ask for specific antibiotics," he said. "The patients know these names. They have been marketed to them, so they know the drugs are available. And antibiotics do give some relief."
According to the report, two national studies show that Americans made more than 17 million visits to health-care facilities for sinus infection between 1999 and 2002. At least one antibiotic was prescribed in nearly 83 percent of cases of acute rhinosinusitis and in nearly 70 percent of cases of the chronic, longer-running version of the condition, in which symptoms persist for at least 12 weeks.
The problem is that antibiotics are effective only against bacteria, but many sinus infections are due to other causes, such as viral infections, allergies or hormonal changes. The often-repeated standard wisdom is that use of antibiotics in such cases should be avoided to reduce the emergence of dangerous resistant bacterial strains.
But it's hard to preach that wisdom to someone with a drippy, hurting sinus who wants immediate relief, Leopold acknowledged. Because more effective drugs are lacking, "patients are desperate, physicians are desperate, and it is not a happy situation," he said.
Consider the case of the working physician called on to treat such a patient, said Dr. Neil L. Kao, vice chairman of the rhinitis/sinusitis committee of the American College of Allergy, Asthma and Immunology. He happens to be just such a working physician, in private practice in Greenville, S.C.
There are ways to determine whether a sinus infection is bacterial, Kao said. One is to do endoscopy, running a tube into the nose to obtain a sample of mucus from the sinus. Another is nasal cytology, examining a swab from the lining of the nose. A third is to take an X-ray.
Ruling out bacterial infection as a cause of sinus inflammation is made difficult by the fact that present protocols detect only the 1% or less of bacteria, fungi and actinomycetes that are able to be grown as monocultures. Better culture techniques and DNA and RNA based techniques to detect "unculturable" bacteria have recently become available. The importance of unculturable bacteria in sinusitis and other diseases is unknown and needs further research.
"The problem with all of these is that they are expensive and time-consuming," Kao said. "The differences between symptoms caused by an allergy, bacterial infection, viral infection and a common cold are few. For us, even specialist doctors, when you see someone with acute nasal symptoms, it is hard to tell the cause. And the truth is that most of the people diagnosed with sinusitis go to primary care doctors."
Public awareness about antibiotic resistance is increasing, but most people suffering from cough, drip, lack of sleep and other sinus symptoms are likely to come in demanding an antibiotic, Kao said.
And so the physician often makes the practical choice of giving what the patient wants, with a chance of relief, over the more abstract issue of antibiotic resistance, he said.
