Objective: This study aimed to compare two sampling methods for nasal nitric oxide in healthy individuals and allergic rhinitis patients, and to examine the within-subject reliability of nasal nitric oxide measurement. Methods: The study included 23 allergic rhinitis patients without concomitant asthma and 10 healthy individuals. For all participants, nitric oxide levels were measured non-invasively from the lungs through the mouth (i.e. the oral fractional exhaled nitric oxide) and the nose. Nasal nitric oxide was measured by two different methods: (1) nasal aspiration via one nostril during breath holding and (2) single-breath quiet exhalation against resistance through a tight facemask (i.e. the nasal fractional exhaled nitric oxide). Results: Compared with healthy participants, allergic rhinitis patients had significantly higher average oral and nasal nitric oxide levels. All methods of nitric oxide measurement had excellent reliability. Conclusion: Nasal nitric oxide measurement is a useful and reliable clinical tool for diagnosing allergic rhinitis in patients without asthma in an out-patient setting. © JLO (1984) Limited 2016.

Parapharyngeal tumors account for 0.5% of head and neck tumors. They are difficult to diagnose because they have few symptoms and are surgically inaccessible. This retrospective study included 61 patients with parapharyngeal space tumors, treated in the last 20 years. The data, obtained from the medical records, included symptoms and clinical signs, diagnostic procedures, surgical approach, postoperative complications and histopathological findings. The most common symptoms were dysphagia, foreign body sensation, pain, and symptom-free patients. For precise tumor localization and its relation to adjacent structures, computerized tomography, magnetic resonance imaging and contrast angiography were used. All the patients were treated surgically. The commonest surgical approach was transcervical, followed by transoral and combined transcervical-transoral. Histopathological examination verified that the origin of these tumors was most frequently salivary or neurogenic. © 2010 International Association of Oral and Maxillofacial Surgeons.
