ABSTRACT: BACKGROUND: The B/B Checker, a new portable device for detecting odorous compounds in oral, exhaled, and nasal air, is now available. As a single unit, this device is capable of detecting several kinds of gases mixed with volatile sulfur compounds (VSC) in addition to other odorous gasses. The purpose of the present study was to evaluate the effectiveness of the B/B Checker for detecting the malodor level of oral, exhaled, and nasal air. METHODS: A total of 30 healthy, non-smoking volunteers (16 males and 14 females) participated in this study. The malodor levels in oral, exhaled, and nasal air were measured using the B/B Checker and by organoleptic test (OT) scores. The VSCs in each air were also measured by gas chromatography (GC). Associations among B/B Checker measurements, OT scores and VSC levels were analyzed using Spearman correlation coefficients. In order to determine the appropriate B/B Checker level for screening subjects with malodor, sensitivity and specificity were calculated using OT scores as an identifier for diagnosing oral malodor. RESULTS: In oral and nasal air, the total VSC levels measured by GC significantly correlated to that measured by the B/B Checker. Significant correlation was observed between the results of OT scores and the B/B Checker measurements in oral (r = 0.892, p < 0.001), exhaled (r = 0.748, p < 0.001) and nasal air (r = 0.534, p < 0.001). The correlation between the OT scores and VSC levels was significant only for oral air (r = 0.790, p < 0.001) and nasal air (r = 0.431, p = 0.002); not for exhaled air (r = 0.310, p = 0.096). When the screening level of the B/B Checker was set to 50.0 for oral air, the sensitivity and specificity were 1.00 and 0.90, respectively. On the other hand, the screening level of the B/B Checker was set to 60.0 for exhaled air, the sensitivity and specificity were 0.82 and 1.00, respectively. CONCLUSION: The B/B Checker is useful for objective evaluation of malodor in oral, exhaled and nasal air and for screening subjects with halitosis. Trial registration: ClinicalTrials.gov NCT01139073.

A 7 yr old Labrador retriever initially presented for severe halitosis, mild ptylism, and depigmentation of the nasal planum. Erythema multiforme was diagnosed based on clinical signs and dermatopathology. Treatment was initiated but the condition did not resolve. Six months later, the dog was diagnosed with a mediastinal mass. Trucut biopsy was performed and histopathologic diagnosis was consistent with a thymoma. A median sternotomy was performed, the thymoma was excised, and the dog ... [Abstract] [Full-text] Diagnosis of erythema multiforme associated with thymoma in a dog and treated with thymectomy.

Eur Arch Otorhinolaryngol. A valid measure of oral malodor (halitosis) and associated quality of life is required for the complete assessment of treatment effectiveness. The purpose of this study was to analyze the psychometric and clinimetric validity of the Halitosis Associated Life-quality Test (HALT) questionnaire, a specific 20-item quality-of-life measure for halitosis. The HALT is a de novo designed tool based on patient interviews and literature review. The University Hospital was the setting for the prospective ...
