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.

Patients with acute laryngitis following an upper respiratory tract infection are often treated with antibiotics for their voice complaints, although, to our knowledge, the effect of such therapy has not been examined. In the present study, comprising 100 adults with laryngitis, the rate of resolution of vocal symptoms, as estimated from voice recordings or subjectively by the patients, was the same in patients who received penicillin V (pcV) as in those who received placebo. Similarly, the degree of rhinorrhea/nasal congestion and cough was not significantly influenced by pcV treatment. At the acute visit, nasopharyngeal cultures revealed Branhamella catarrhalis in 50%, Hemophilus influenzae in 15% and Streptococcus pneumoniae in 1% of the patients; the rate of elimination of these bacteria was the same in the pcV as in the placebo group. Thus, while suggesting that B catarrhalis and H influenzae are important for the pathogenesis of the disorder, our results do not provide support for the use of pcV in acute laryngitis.

This review examines the issues surrounding short-course antibiotic therapy of acute sinusitis. Acute bacterial sinusitis is a common community-acquired infection defined as inflammation of one or more paranasal sinuses, most often the maxillary sinus. It is estimated that 0.5-5% of colds are complicated by acute sinusitis. Up to 1 in 20 upper respiratory tract infections is complicated by bacterial sinusitis, most often caused by Streptococcus pneumoniae, Haemophilus influenzae, Moraxella catarrhalis and Staphylococcus aureus. Early diagnosis and appropriate antibiotic therapy, in combination with agents that relieve nasal congestion, are important factors in preventing suppurative complications. Left untreated, it could lead to the development of chronic sinusitis or epidural or subdural empyema, brain abscess, or cavernosus sinus thrombosis. Isolation of the causal organism is often lacking in the community setting. Empiric antibiotic therapy should provide adequate coverage against the most important pathogens. Guidelines from different specialist societies based on current scientific knowledge are helpful in making the decision on which drug to use. Recommendations for duration of treatment of acute sinusitis are inconsistent between different guidelines but usually a 10- to 14-day treatment course is recommended.Recognition that the 10- to 14-day duration of therapy is not derived from a strong scientific or medical rationale has led some clinicians to call for shortening the duration of antibiotic therapy for patients with upper respiratory tract infections. Accumulating evidence suggests that short-course (< or =5 days) antibiotic therapy may have equivalent or superior efficacy compared with traditional longer (10-14 days) therapies and offers a number of advantages. Results of a number of clinical trials investigating 5-day therapy with oral cephalosporins, new quinolones or ketolides in acute (presumed) bacterial sinusitis in comparison with traditional 10-day treatment courses have been published demonstrating equivalent efficacy of 5-day and 10-day regimens. The evidence reviewed in this article strongly supports reduction of the traditional 10-day course of antibacterial therapy to a 5-day course for uncomplicated acute maxillary sinusitis in adults. Further research related to the duration of antibacterial therapy for sinusitis is needed in children and in adult patients with frontal, ethmoidal and sphenoidal sinusitis.
