Cefprozil is a beta-lactamase-stable oral cephalosporin with an antimicrobial spectrum that includes gram-positive and gram-negative pathogens commonly associated with acute bacterial sinusitis, one of the most common upper respiratory tract infections among adults. We conducted a multicenter, open-label study to compare the efficacy and safety of cefprozil and amoxicillin/clavulanate in the treatment of adults with severe acute bacterial sinusitis diagnosed by clinical and radiographic criteria. A total of 278 patients entered the study, 140 (59 males, 81 females) in the cefprozil group and 138 (69 males, 69 females) in the amoxicillin/clavulanate group. Patients were randomized to 10 days of treatment with either cefprozil 500 mg BID or amoxicillin/clavulanate 500 mg/125 mg TID. Clinical severity was assessed at study entry, and patients were stratified based on symptom grade. Efficacy was evaluated using a 10-point questionnaire administered during, at the end of, and 2 weeks after completing therapy. At the end of treatment, 84.5% (71/84) of patients with severe sinusitis treated with cefprozil had a satisfactory clinical response, which was not significantly different from the 89.9% (80/89) of patients in the amoxicillin/clavulanate group who had a satisfactory clinical response. Two weeks after completing treatment, 80.8% (63/78) of cefprozil-treated patients and 81.0% (64/79) of amoxicillin/clavulanate-treated patients with severe sinusitis had a satisfactory response. Relapse was more common among amoxicillin/clavulanate patients (6/70; 8.6%) than among cefprozil patients (2/65; 3.1%), but the difference was not statistically significant. Significantly more amoxicillin/clavulanate-treated patients experienced adverse events compared with cefprozil-treated patients (P < 0.001), including diarrhea (P < 0.001), nausea (P < 0.042), and rash (P < 0.035). Three times as many amoxicillin/clavulanate patients discontinued treatment because of adverse events. Cefprozil demonstrated comparable clinical efficacy to amoxicillin/clavulanate in the treatment of adults with severe sinusitis; however, cefprozil was associated with a significantly lower incidence of diarrhea, nausea, and rash.

The activity, pharmacokinetics, pharmacodynamics, efficacy, safety, drug interactions, and dosage and administration of moxifloxacin are reviewed. Moxifloxacin is an oral 8-methoxyquinolone antimicrobial approved in December 1999 for use in the treatment of acute bacterial sinusitis, acute bacterial exacerbations of chronic bronchitis, and community-acquired pneumonia. This fluoroquinolone is active against common community-acquired respiratory pathogens (Streptococcus pneumoniae, Haemophilus influenzae, Moraxella catarrhalis), atypical pathogens, and many anaerobes. Moxifloxacin has an absolute bioavailability of 90% after oral administration and a mean elimination half-life of 12 hours. The drug is not a substrate or inhibitor of the hepatic cytochrome P-450 isoenzyme system thereby avoiding many potential drug interactions. Moxifloxacin has limited phototoxic potential. In clinical trials, moxifloxacin had clinical success rates of 88-97% and bacteriologic eradication rates of 90-97%. Reported adverse effects were primarily gastrointestinal (nausea, diarrhea) and were mild to moderate in severity. Moxifloxacin prolongs the QT interval by a mean + S.D. of 6 +/- 26 milliseconds above baseline and should be used with caution in patients with proarrhythmic conditions and avoided in patients receiving antiarrhythmia agents, such as quinidine, procainamide, amiodarone, and sotalol. The standard oral dosage is 400 mg once a day. Dosage adjustment is unnecessary in patients with renal dysfunction or mild to moderate hepatic dysfunction. Moxifloxacin is a safe and effective antimicrobial that will be useful for treating acute sinusitis, acute bacterial exacerbations of chronic bronchitis, and community-acquired pneumonia.

Respiratory tract infections (RTIs), the most common indication for outpatient antimicrobial therapy, impose a heavy medical and societal burden and present a difficult therapeutic challenge in the face of increasing pathogen resistance worldwide. Gatifloxacin is a new broad-spectrum fluoroquinolone with excellent activity against prevalent respiratory bacteria, including penicillin-resistant Streptococcus pneumoniae and atypical pathogens. A multicenter, open-label, noncomparative surveillance study carried out in Mexico evaluated the safety and efficacy of oral gatifloxacin 400 mg once daily in 17,923 adult outpatients with community-acquired pneumonia (CAP) (n = 3322), acute exacerbations of chronic bronchitis (AECB) (n = 5885), and acute bacterial sinusitis (n = 8716). Voluntary, unpaid physician participation contributed to an unbiased study design. Physician-assessed global rate of cure or improvement was 96.3%; efficacy was 95.8% in CAP, 96.1% in AECB, and 96.4% in sinusitis. The incidences of relapse (1.5%) and therapeutic failure (0.7%) were low. The most commonly reported adverse events, nausea (2.76%), headache (2.20%), and dizziness (1.33%), were generally mild and self-limited. Oral gatifloxacin 400 mg once daily is effective and safe for patients with CAP, AECB, and acute sinusitis.

Telithromycin, the first member of the ketolide antibacterials, has good activity against community-acquired respiratory pathogens, including multiple-drug-resistant strains of Streptococcus pneumoniae. Telithromycin 800 mg once daily has been US FDA approved for the treatment of acute bacterial sinusitis (ABS; treatment duration 5 days), acute bacterial exacerbations of chronic bronchitis (AECB; 5 days) and mild-to-moderate community-acquired pneumonia (CAP; 7-10 days). In patients with CAP, telithromycin was as effective as amoxicillin 1000 mg three times daily for 10 days, clarithromycin 500 mg twice daily for 10 days or trovafloxacin 200 mg once daily for 7-10 days. In patients with AECB, telithromycin was as effective as a 10-day regimen of amoxicillin/clavulanic acid 500/125 mg three times daily, cefuroxime axetil 500 mg twice daily or clarithromycin 500 mg twice daily. In patients with ABS, telithromycin was as effective as a 10-day course of amoxicillin/clavulanic acid 500/125 mg three times daily or cefuroxime axetil 250 mg twice daily. Telithromycin was generally well tolerated and most adverse events were of mild-to-moderate severity and transitory. The most common adverse events with telithromycin were diarrhoea and nausea (10.8% and 7.9% of 2702 patients in clinical trials); these events occurred in 8.6% and 4.6% of 2139 comparator-treated patients.

The prompt identification of sepsis in children is challenging, but once sepsis is identified, initiation of care and determination of proper disposition may be insufficient to ensure optimal outcomes. The best opportunity for full recovery also requires rapid identification and treatment of the infectious source. Acute bacterial sinusitis is common in the pediatric population, and although intracranial complications of sinusitis are rare, they are associated with significant morbidity and mortality. History and physical examination may be imperfectly sensitive for the presence of acute bacterial sinusitis and its intracranial complications. We present a case of pediatric sepsis in which the diagnosis of intracranial extension of bacterial sinusitis was not made during the first phase of care and describe complications that followed. Emergency physicians should consider subdural empyema in patients presenting with fever, nausea and headache with worrisome vital signs and laboratory values suggestive of a severe infection.

Approximately 0.5-2% of upper viral infections are com-licated by secondary acute bacterial sinusitis and may in rare cases evolve into more serious complications such as meningitis and intracranial abscess. Symptoms are often subtle and nonspecific as fever, headache, scalp tenderness, nausea and altered mental status. In this case report of a 12-year-old boy with an epidural abscess secondary to sinusitis we intend to increase the knowledge to these rare, but potentially life-threatening complications to ensure the optimal and timely treatment.
