Evaluation of the patient with sore throat, earache, and sinusitis: an evidence based approach

Community-Based Treatment of Acute Uncomplicated Bacterial Rhinosinusitis with Gatifloxacin

OBJECTIVE: We sought to evaluate gatifloxacin in adults with acute uncomplicated bacterial rhinosinusitis.

STUDY DESIGN: TeqCES was an open-label, multicenter, noncomparative study of the safety and efficacy of gatifloxacin. More than 11,000 adult patients with acute uncomplicated rhinosinusitis received gatifloxacin 400 mg once daily for 10 days.

RESULTS: Moraxella catarrhalis (91% β-lactamase producers), Haemophilus influenzae (28% β-lactamase producers), Streptococcus pneumoniae (18% intermediately resistant and 14% fully resistant to penicillin), and Staphylococcus aureus were the predominant pathogens isolated from purulent nasal discharge. More than 99% of rhinosinusitis pathogens isolated from the nasopharynx of patients meeting the clinical criteria for rhinosinusitis were susceptible to gatifloxacin. Among 10,353 patients whose clinical response could be determined, 91.6% were cured. Clinical cure rates exceeded 90% for the major pathogens. Gatifloxacin was well tolerated; drug-related adverse events that occurred in 1% or more of patients were nausea (4.4%), dizziness (1.8%), diarrhea (1.4%), and headache (1.0%).

CONCLUSION: Gatifloxacin is effective for patients with acute bacterial rhinosinusitis in the community.!

Earache

Earache, a common emergency department presentation, may be caused by a variety of conditions, some distant from the ear. This article discusses the diagnosis and treatment of acute otitis media, otitis media with effusion, otitis externa, otitis media with ruptured tympanic membrane or tympanostomy tubes, malignant otitis externa, mastoiditis and petrositis, traumatic ruptured tympanic membrane, cerumen impactions, and foreign bodies in the ears.

Otalgia

The patient presenting with otalgia poses a diagnostic challenge for which orderly and diligent evaluation and management is needed. The etiology of otalgia can be either primary or referred, and a detailed history and physical examination with directed studies as indicated can elucidate the cause of the pain.

Diagnosis and management of acute otitis media in the urgent care setting

The prevalence of otitis media is increasing, which affects health care resource utilization across all segments, including the urgent care setting. One of the greatest challenges in the management of acute otitis media (AOM) is the effective treatment of cases caused by pathogens that are resistant to commonly used antibiotics. Whereas the production of beta-lactamases among strains of Haemophilus influenzae and Moraxella catarrhalis is an important consideration for antimicrobial therapy, the high prevalence of resistance to penicillin and other classes of antibiotics among strains of Streptococcus pneumoniae represents a greater clinical concern. The Centers for Disease Control and Prevention (CDC) recently convened the Drug Resistant S. pneumoniae Therapeutic Working Group to develop evidence-based recommendations for the treatment of AOM in an era of prevalent resistance. The recommendations from this group included amoxicillin as the preferred first-line drug because of the demonstrated activity against penicillin-intermediate and -resistant strains of S. pneumoniae, using higher dosages of up to 90 mg/kg per day in certain settings. For patients in whom initial treatment is unsuccessful after 3 days, the recommended agents included high-dose amoxicillin-clavulanate (for activity against beta-lactamase-producing pathogens), clindamycin, cefuroxime axetil, or 1 to 3 doses of intramuscular ceftriaxone. The principles set forth in these guidelines can assist the therapeutic decisionmaking process for practitioners in the urgent care setting.

Appropriate use of antibiotics for common infections in an era of increasing resistance

In many respects, antibiotics have changed medicine forever. Countless lives have been enhanced and saved with antibiotic use. Unfortunately, the medical community has opened Pandora's box through the casual distribution of outpatient antibiotics. Society will indeed suffer, as well as the medical profession, if antibiotics are not used judiciously. To date, the rate of penicillin resistance has steadily risen in North America and in many other areas of the world. Much of the increase in resistance has been caused by the distribution of antibiotics for viral infections (e.g., bronchitis, colds, or purulent nasal discharge) as well as nonstreptococcal throat infections. Parental pressure for physicians to prescribe antibiotics also has contributed to the rise in antibiotic resistance. The authors have discussed many common pediatric ED infections and have illustrated the key points for making the diagnosis of each. In addition, the authors also recommend the appropriate choice of antibiotics for each disease process, with an emphasis on narrow-spectrum, first-line antimicrobials. Physicians, as the "holders of the prescription pad," should be aware of the problems with increasing bacterial resistance especially ED practitioners who work on the front line. In addition, families and patients should be educated about the harm of inappropriate antibiotic use. The AAP publishes pamphlets for parents that discuss these issues. It is believed, as was seen in Finland and Japan, that judicious use of antibiotics leads to a decrease in resistant bacteria and prolong antibiotic usefulness. This is an issue of great importance to the long-term health of patients. What Benjamin Rush stated in 1789 is true today: "Do not condemn, or oppose, unnecessarily, the simple, prescriptions of your patients. Yield to them in matters of little consequence but maintain an inflexible authority over matters that are essential to life."
