Sinusitus Definition: Sinusitis is an inflammation, or swelling, of the tissue lining the sinuses. Normally, sinuses are filled with air, but when sinuses become blocked and filled with fluid, germs (bacteria, viruses, and fungi) can grow and cause an infection.
Symptoms :Postnasal drip Discolored nasal discharge (greenish in color) Nasal stuffiness or congestion Tenderness of the face (particularly under the eyes or at the bridge of the nose) Frontal headaches Pain in the teeth Coughing Fever Fatigue Bad breath.
Statistics In spite of these problems, some data are available. In the USA the prevalence of sinusitis is estimated to be 14% of the global population.In 1979 Albegger calculated the prevalence of sinusitis in a general population to range from 32% in young children to 5% in adults.In the USA chronic sinusitis accounted for 24 million patient visits in 1992 (an increase of eight million compared with 1989). The primary care physician was the first line practitioner in 85% of cases; 97% of the patients who visited their physicians with sinusitis (in 1992) received a prescription. A total of $200 million was spent on the treatment of chronic sinusitis. It seems that the prevalence of sinusitis is increasing. Between 1990 and 1992 patients with sinusitis in the USA reported approximately 73 million days of restricted activity, an increase from the 50 million days reported between 1986 and 1988.5 In 1998 Beauvillain de Montreuil reported, in a multivariate analysis, that chronic bronchitis, corticosteroids, atopy, occupational rhinitis, and local decongestants were the most important factors influencing the transformation to a chronic form of sinusitis. Patients with particular diseases develop sinusitis more often—for example, 25–30% of allergic patients, 43% of asthmatic patients, 37% of patients with transplants, and 54–68% of patients with AIDS.
