Rhinosinusitis

Abstract
The author designed a study to assess the healing properties of platelet-rich plasma (PRP) after endoscopic sinus surgery in 30 patients with bilateral and symmetrical chronic rhinosinusitis that was refractory to medical management. At the conclusion of each operation, PRP was introduced into the middle meatus of a randomly chosen side, while the other side was treated normally and served as a control. Patients were followed until both sides healed. After 13 operations, follow-up evaluations demonstrated no benefit to the use of PRP, and the study was terminated early. In general, both sides healed quickly and uneventfully as expected. There appears to be no advantage to the use of PRP in endoscopic sinus surgery.

Abstract
We evaluated the efficacy of a new pharmacokinetically enhanced formulation of amoxicillin/clavulanate (2,000/125 mg) twice daily for the treatment of acute bacterial rhinosinusitis (ABRS) caused by Streptococcus pneumoniae, particularly penicillin-resistant S pneumoniae (PRSP; penicillin minimum inhibitory concentrations [MICs]: ≥2 µg/ml. A total of 2,482 patients received study medication (safety population). Of these, 2,324 were clinically evaluable (efficacy population), and 1,156 of them had at least one pathogen isolated at screening (bacteriology population). S pneumoniae was isolated from 371 patients in the bacteriology population, including 37 with PRSP. Follow-up in the bacteriology population on days 17 through 28 revealed that amoxicillin/clavulanate therapy was successful in 345 of 371 patients with S pneumoniae infection (93.0%) and in 36 of 37 patients with PRSP infection (97.3%), including 7 of 8 patients (87.5%) whose amoxicillin/clavulanic acid MICs were 4/2 µg/ml or higher. Pharmacokinetically enhanced amoxicillin/clavulanate was generally well tolerated, as only 2.2% of patients withdrew because of adverse events. This agent represents a valuable new therapeutic option for the empiric treatment of ABRS, particularly in areas where antimicrobial-resistant pathogens (including β-lactamase'positive organisms) are prevalent, and for the treatment of patients who are at increased risk of infection with PRSP.

 

Associations between fatigue and medication use in chronic rhinosinusitis

Abstract
We conducted a prospective study of 586 adults to determine if associations exist between fatigue symptom scores and three classes of medications prescribed for the treatment of chronic rhinosinusitis (CRS): prescription nonsedating antihistamines, topical nasal steroids, and antibiotics. Patients were assessed with the assistance of the Rhinosinusitis Symptom Inventory and Likert-scale fatigue symptom scores. On multivariate analysis and correcting for disease severity, we found that significantly higher fatigue symptom scores were associated with the use of nonsedating antihistamines (mean Likert score: 2.75 vs. 2.27 for patients not taking a nonsedating antihistamine; p = 0.029). Higher fatigue scores were also associated with a greater number of antibiotic courses and more total weeks of antibiotic use (p < 0.001 in both cases). No association was seen between fatigue scores and the use of topical nasal steroids (mean Likert score: 2.65 vs. 2.24; p = 0.658). We recommend that long-term use of a nonsedating antihistamine be scrutinized in CRS patients who report symptoms of fatigue.

Does Helicobacter pylori play a role in upper respiratory tract inflammation? A case report

Abstract
Persistent isolated inflammation of the sphenoid sinus, an entity that is not diagnosed very often, poses a challenge to clinicians and researchers alike. Its features tend to suggest that its etiopathogenesis is different from that of more common forms of chronic rhinosinusitis. We report the case of a 54-year-old woman who had a history of distressing chronic postnasal drip and a globus sensation with opacification of the sphenoid sinus. She was diagnosed with gastroesophageal reflux, and Helicobacter pylori was detected in her gastric contents and in the inflamed mucosa of the sphenoid sinus, as well. Complete symptom relief was achieved only after she had undergone surgical sphenoidotomy and treatment with anti'H pylori medication. We discuss the potential for this ubiquitous gastric bacterium to play a role in at least some forms of chronic sinonasal inflammation.
