Allergic rhinitis in children is often complicated by bacterial sinusitis, which can lead to chronic illness and dysfunction. Sinus disease manifests differently in children than in adults, with cough, rhinorrhea, and middle ear disease being common and pain, headache, and fever being uncommon. Sinusitis may exacerbate asthma, and as many as 70% of children with allergy and chronic rhinitis have abnormal findings on sinus x-ray studies. Nasal cytologic specimens showing large numbers of polymorphonuclear cells with intracellular bacteria are also evidence of sinusitis. Obstruction of the nasal airways by allergic rhinitis or enlarged adenoids can lead to deviations in facial growth, specifically increased facial length. With the removal of the obstruction and a return to nasal breathing, facial length may become more normal. Sinusitis in children is treated with antibiotics, usually for 3 to 4 weeks, to eliminate the infection. Adjunctive therapy with antihistamines, decongestants, cromolyn, and corticosteroids may also be helpful. Topical steroids, such as flunisolide and beclomethasone, can be very useful in pediatric patients. These steroids decrease edema and prevent the release of allergic mediators that may be responsible for an environment favoring the bacterial infection causing sinusitis.

Upper respiratory tract infection and allergic inflammation are recognized as the important risk factors for acute sinusitis, with upper respiratory tract infection being most common. In children with acute or chronic sinusitis, the respiratory symptoms of nasal discharge, nasal congestion and cough are usually prominent. Radiography has traditionally been used to determine the presence or absence of sinus disease. The radiographic findings most diagnostic of bacterial sinusitis are diffuse opacification, mucous membrane thickening or an air-fluid level. The predominant organisms include Streptococcus pneumoniae, Branhamella catarrhalis and nontypable Haemophilus influenzae. Several viruses including adenovirus and parainfluenzae have also been recovered. Clinical improvement is prompt in nearly all children treated with an appropriate antimicrobial agent.

We sought to correlate the clinical, radiographic, and bacteriologic findings in maxillary sinusitis in 30 children who had both upper-respiratory-tract symptoms and abnormal maxillary radiographs. Cough, nasal discharge, and fetid breath were the most common signs, but fever was present inconsistently. Facial pain or swelling and headache were prominent symptoms in older children. Bacterial colony counts of greater than or equal to 10(4) colony-forming units per milliliter were found in 34 of 47 sinus aspirates obtained from 23 children. The most common species recovered were Streptococcus pneumoniae, Haemophilus influenzae, and Branhamella catarrhalis. No anaerobic bacteria were isolated. Viruses were isolated from only two sinus aspirates. There was a poor correlation between the predominant species of bacteria recovered from either the nasopharyngeal or throat culture and the bacteria isolated from the sinus aspirate. This study demonstrates that children with both upper-respiratory-tract symptoms and abnormal sinus radiographs are likely to harbor bacteria in their sinuses, suggesting that such children have bacterial sinusitis.

Acute bacterial sinusitis (ABS) is an extremely common problem in both children and adults. There are three clinical presentations of acute sinusitis: (1) onset with persistent symptoms (nasal symptoms or cough or both for > 10 but < 30 d without evidence of improvement); (2) onset with severe symptoms (high fever and purulent nasal discharge for 3-4 consecutive days); and (3) onset with worsening symptoms (respiratory symptoms, with or without fever, which worsen after several days of improvement). Images to confirm the presence of acute sinusitis are necessary in older children (> 6 years) and adults to enhance the certainty of diagnosis. The predominant bacterial species that are implicated in acute sinusitis are Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis in children. In the last decade, there has been an increasing prevalence of penicillin-resistant S. pneumoniae, and beta-lactamase-producing H. influenzae and M. catarrhalis. Although there has been some controversy in the literature regarding the effectiveness of antibiotics in the treatment of ABS, most studies in which the diagnosis of acute bacterial sinusitis is confirmed with images and appropriate anti-biotics are prescribed show superior outcomes in recipients of antibiotics. Therapy may be initiated with high-dose amoxicillin or amoxicillin-clavulanate. In penicillin-allergic patients or those who are unresponsive to amoxicillin, amoxicillin-clavulanate is appropriate. Alternatives include cefuroxime, cefpodoxime, or cefdinir. In cases of serious drug allergy, clarithromycin or azithromycin may be prescribed. The optimal duration of therapy is unknown. Some recommend treatment until the patient becomes free of symptoms and then for an additional 7 d.
