Eighty-one adults with symptoms of acute sinusitis were studied by direct needle puncture and aspiration of the maxillary sinus (105 sinuses). Fifty-nine bacterial strains were isolated in titers of greater than or equal to 10(4) colony-forming units/ml; Streptococcus pneumoniae and Haemophilus influenzae accounted for 64% of the isolates. Other bacteria recovered included anaerobes (12%), Neisseria species (8.5%). Streptococcus pyogenes (3%), alpha-hemolytic Streptococcus (3%), non-group A beta-hemolytic Streptococcus (3%), Staphylococcus aureus (2%), Pseudomonas aeruginosa (2%), and Escherichia coli (2%). Viruses were isolated from 11 sinuses; these isolates included rhinovirus (six), influenza A (H3N2) virus (three), and two types of parainfluenza virus (one each). The efficacy of therapy with orally administered ampicillin, amoxicillin, or trimethoprim-sulfamethoxazole was evaluated by a repeat sinus puncture and culture. Clinical and bacteriologic responses to all three regimens were good.

Twenty-four adults with clinical evidence of sinusitis were studied by 65 needle punctures of the maxillary antrum. Fourteen of 15 sinuses with normal transillumination and 19 of 26 that were dull had normal aspirates, whereas 24 of 24 that were opaque had abnormal aspirates (P less than 0.001). Marked mucosal thickening as determined radiologically (Water's view) was associated with abnormal aspirates whereas lesser mucosal thickening was not (P less than 0.001). In acute sinusitis, there was a strong correlation between high aspirate leukocyte counts (greater than 1000 per cubic millimeter) and infection as manifested by bacterial titers of greater than 10(5) per milliliter or the isolation of virus fungus (P greater than 0.001). Anterior-nasal-swab cultures correlated poorly with direct aspirate culters. Organisms frequently recovered from the sinus included Haemophilus influenzae, Strepto coccus pneumoniae, and anaerobic bacteria. Rhinovirus was recovered twice. Antibiotics were usedful in patients with acute sinusitis if the organism was sensitive in vitro (P less than 0.001).

Haemophilus influenzae is an aerobic pleomorphic gram-negative coccobacillus that requires both X and V factors for growth. It grows poorly, if at all, on ordinary blood agar unless streaked with Staph. aureus. It grows well on chocolate agar. Because this medium is often not used in culturing specimens from adults and because the organism may be overgrown by other bacteria, the frequency of H. influenzae infections has undoubtedly been seriously underestimated. This is aggravated by the failure of many physicians to obtain blood cultures in suspected bacterial infections and the failure of many laboratories to subculture them routinely onto chocolate agar. H. influenzae, along with Streptococcus pneumoniae, is a major factor in acute sinusitis. It is probably the most frequent etiologic agent of acute epiglottitis. It is probably a common, but commonly unrecognized, cause of bacterial pneumonia, where it has a distinctive appearance on Gram stain. It is unusual in adult meningitis, but should particularly be considered in alcoholics; in those with recent or remote head trauma, especially with cerebrospinal fluid rhinorrhea; in patients with splenectomies and those with primary or secondary hypogammaglobulinemia. It may rarely cause a wide variety of other infections in adults, including purulent pericarditis, endocarditis, septic arthritis, obstetrical and gynecologic infections, urinary and biliary tract infections, and cellulitis. Antimicrobial susceptibility testing is somewhat capricious in part from the marked effect of inoculum size in some circumstances. In vitro and in vivo results support the use of ampicillin, unless the organism produces beta-lactamase. Alternatives in minor infections include tetracycline, erythromycin, and sulfamethoxazole-trimethoprim. For serious infections chloramphenicol is the best choice if the organism is ampicillin-resistant or the patient is penicillin-allergic.

We review the literature on orbital involvement in acute sinusitis in children. Because of the potential severity of the disease which may be life threatening a vigorous treatment is required. Hemophilus Influenzae is a major cause of orbital cellulitis followed by Staphylococcus Aureus and group A streptococcus. Because of the emergence of Ampicillin-Resistant H. Influenzae strains in Belgium, chloramphenicol should be included in the initial therapy in combination with a penicillinase resistant semisynthetic penicillin. Therapy is adjusted as soon as the results of bacterial culture are known. Surgical establishment of sinus or abscess drainage is required if the child is severely ill or failed to respond to medical treatment. A treatment protocol is proposed.

Two different studies were performed in order to determine the role of aerobic and anaerobic bacteria in sinusitis. Aerobes: A retrospective study of 331 cases of all types of sinusitis (from 1963 till 1975) showed an increasing occurrence of Haemophilus influenzae during the last three years. Only in the acute sinusitis is Streptococcus pneumoniae more frequently found than Haemophilus influenzae, which exhibits the highest occurrence in chronic and undeterminable cases. We found cultures with pathogenic aerobes in 64% of the acute and 56% of the chronic cases of sinusitis. Anaerobes: A prospective study of 100 sinus secretions from 66 patients with paranasal sinusitis showed the great importance of anaerobes; they were present in 33% of samples, pure anaerobic cultures in 12% and mixed aerobic-anaerobic in 21%. Peptostreptococcus sp. showed the highest occurrence (15%). Anaerobic sinusitis is more frequent in unilateral cases. The presence of anaerobes is not dependent on the patient's age or the duration of the sinusitis. In 76% the anaerobes disappeared after the initial antral irrigation.

Clinical effect of amoxicillin was evaluated in 29 cases of the acute infections of ear, nose and throat: 8 cases of acute purulent otitis media, one case of acute otitis externa, one case of furuncle of the ear, 2 cases of acute sinusitis, 12 cases of acute lacunar tonsillitis, 2 cases of pharyngolaryngitis, one case of acute cervical lymphadenitis, one case of phlegmon of the face and one case of acute gingivitis. The following results were obtained from the clinical and laboratory studies. 1) The therapeutic results were excellent in 18 cases, good in 5 cases, fair in 3 cases and poor in 3 cases. The effect was observed in 79.3% of the patients treated. 2) The causative bacteria were: 3 strains of beta-Streptococcus hemolyticus, 4 strains of Hemophilus, 4 strains of Staphylococcus aureus, one strain of Diplococcus pneumoniae, one strain of Gram-positive Diplococcus and Gram-negative Bacillus. Clinically good results were obtained in patients infected with beta-Streptococcus hemolyticus, Hemophilus and Diplococcus pneumoniae. 3) No side effect was observed with amoxicillin, except slight diarrhea in one case. This side effect disappeared by cessation of the administration. 4) No unfavourable influence was noticed on peripheral blood, liver function nor renal function by administration of amoxicillin. 5) From the results of this series, amoxicillin seems to be useful in the treatment of acute infections of the ear, nose and throat.

Normal mucociliary flow is a significant defense mechanism in the prevention of acute sinusitis. We have undertaken a study to examine the early sinus mucosal and mucociliary changes that occur in response to acute infection. Twenty rabbits were evaluated for 5 days after an obstructed maxillary sinus was inoculated with either Streptococcus pneumoniae, Hemophilus influenzae, Pseudomonas aeruginosa, or a sterile saline solution. Data collected included measurements of sinus mucosal ciliary beat frequency, quantitation of ciliated cell losses, and electron microscopic observations. Results demonstrate statistically significant (p < 0.05) changes in mucosal ciliary beat frequency that were either excitatory or inhibitory, depending both on the length of the infection and the specific organism. No changes in ciliary beat frequency were observed in the control animals (p > 0.55). Control animals likewise demonstrated no loss of ciliated cells from mucosal epithelium; however, dramatic losses of ciliated cells from the sinus mucosa of the experimental groups were observed. These losses occurred at different rates, depending on the infecting organism, but all infected groups demonstrated a > 86% decrease in the number of viable ciliated cells from the sinus mucosa after sinusitis of 5 days duration. We conclude that a significant loss of ciliated cells from sinus mucosa and a corresponding disruption of normal mucociliary flow occurs early after exposure to pathogenic organisms and is a significant predisposing factor in the development of acute sinusitis.

To determine the bacteriologic cause of acute sinusitis, a sample of sinus secretions must be obtained from one of the paranasal sinuses without contamination by normal respiratory or oral flora that colonize mucosal surfaces. When maxillary sinus aspiration is performed on children who have signs and symptoms of acute sinusitis, bacteria are recovered in high density from 70%. In patients with acute, subacute, or chronic sinusitis who are generally well except for persistent respiratory symptoms, of nasal discharge or cough or both, the usual bacterial isolates are Streptococcus pneumoniae, Haemophilus influenzae, an Moraxella catarrhalis. In contrast, anaerobic organisms and staphylococci should be suspected in patients who have very long-standing symptoms or in those whose symptoms are so severe or complicated that sinus surgery is undertaken.

Acute sinusitis is a common complication of upper respiratory tract infections in children. The primary causative bacteria are Haemophilus influenzae, Moraxella catarrhalis, Streptococcus pneumoniae, Streptococcus pyogenes, and alpha-hemolytic streptococci. Concurrent viral infection may confound interpretation of the clinical response to antimicrobial treatment. First-line antimicrobial treatment is usually with amoxicillin. The increase in frequency of beta-lactamase-producing bacteria in some communities, however, may warrant empirical treatment with other drugs such as amoxicillin/clavulanate, trimethoprim-sulfamethoxazole, cefixime, or cefuroxime. With the marketing of newer antimicrobial drugs for treating sinusitis, it is important for physicians to understand the criteria for evaluating the efficacy of each new drug in relation to existing antimicrobial agents. Criteria for clinical and bacteriologic evaluation of new antimicrobial drugs in the treatment of sinusitis in children are described.

In a noncomparative trial, 73 adults with acute sinusitis confirmed by x-ray received cefixime 400mg once daily for approximately 10 days. At the end of treatment, 60 patients (82%) were cured, 2 (2.7%) had improved and 7 (9.6%) had failed therapy; 4 patients were not evaluable. No relapses were observed at follow-up. Haemophilus influenzae, Streptococcus pneumoniae and Branhamella (Moraxella) catarrhalis were the main pretreatment pathogens, accounting for 65% of all bacterial isolates. Overall, 84% of pathogens were eradicated after treatment. Cefixime was well tolerated, moderate gastrointestinal disturbances being the most frequent adverse effects noted (3 of 4 patients with adverse effects). These results are comparable to those obtained with cefixime 400mg administered orally in 2 divided doses.
