An 11-year-old boy was admitted with mildly painful swallowing. His parents mentioned he had had bad breath for 4 months. He had presented with the same complaint several times at medical centres, and some antibiotics and analgesics were given. During examination, bad breath (halitosis) was noted (figure 1). There was no cervical and submandibular lymphadenopathy and fever. edpract;archdischild-2018-315509v1/F1F1F1Figure 1Oropharyngeal examination on admission.

Frequent or persistent malodor (halitosis) represents a considerable embarrassment to those affected. French pine bark extract, Pycnogenol® (PYC), has displayed antibacterial activity against a broad range of bacterial species. In the present study, anticipated benefits of PYC on diminishing halitosis were investigated. Ten healthy males and 11 females, aged 40.1±12.3 y, were recruited based on threshold breath sulfur compounds presence, diagnosed by portable gas chromatography. Subjects were randomly assigned to either sugar-free gums, or gums bearing an additional 2.5 mg PYC per piece. The subjects were required to consume two pieces of PYC or placebo gum six times daily for 15 min. The levels of volatile sulfur compounds (VSCs), measured by OralChromaTM, and tongue-coating score were recorded at baseline, 2, and 4 wk. Hydrogen sulfide-producing bacteria in saliva were cultured on Brucella blood agar plates containing 0.05% cysteine, 0.12% glutathione, and 0.02% lead acetate. The group consuming PYC chewing gum reduced exhaled hydrogen sulfide, methyl mercaptan and dimethyl sulfide significantly (p<0.01) after 2 wk versus baseline. Continuation of daily PYC-gum consumption for 4 wk remarkably lowered the tongue-coating score and exhaled hydrogen sulfide was significantly decreased compared to the placebo group. PYC chewing gum significantly reduced hydrogen sulfide-producing bacteria in saliva after 4 wk (p<0.01), with no effects observed in the placebo control. The results suggest that PYC chewing gum is effective in reducing oral malodor by decreasing the accumulation of tongue coating and the number of hydrogen sulfide-producing bacteria in saliva.

- JBJ Breath Res 2018 Jun 27
- CONCLUSIONS: Probiotics may be beneficial in treating intra-oral halitosis. However, due to limited data and the heterogeneity of the studies, the efficacy of probiotics remains unclear. Studies with more subjects and standardised protocols need to be designed.

Esophageal diverticulum is a rare entity with symptoms that include dysphagia, halitosis, chest pain, and regurgitation. Indications for surgery include the presence of any of these symptoms and a diverticulum larger than 3 cm because of the increased risk of malignancy and aspiration. Treatment is open or minimally invasive surgery performed from the transhiatal or transthoracic approach.

Bimodally meso- (2-50 nm) and macroporous (>50 nm) WO3 microbelts (MBs) functionalized with sub-3 nm Pt catalysts were fabricated via the electrospinning technique followed by subsequent calcination. Importantly, apoferritin (Apo), tea saponin and polystyrene colloid spheres (750 nm) dispersed in an electrospinning solution acted as forming agents for producing meso- and macropores on WO3 MBs during calcination. Particularly, mesopores provide not only numerous reaction sites for effective chemical reactions, but also facilitate gas diffusion into the interior of the WO3 MBs, dominated by Knudsen diffusion. The macropores further accelerate gas permeability in the interior and on the exterior of the WO3 MBs. In addition, Pt nanoparticles with mean diameters of 2.27 nm were synthesized by using biological protein cages, such as Apo, to further enhance the gas sensing performance. Bimodally porous WO3 MBs functionalized by Pt catalysts showed remarkably high hydrogen sulfide (H2S) response (Rair/ Rgas = 61 @ 1 ppm) and superior selectivity to H2S against other interfering gases, such as acetone (CH3COCH3), ethanol (C2H5OH), ammonia (NH3), and carbon monoxide (CO). These results demonstrate a high potential for the feasibility of catalyst-loaded meso- and macroporous WO3 MBs as new sensing platforms for the possibility of real-time diagnosis of halitosis.

Lead(II) acetate [Pb(Ac)2] reacts with hydrogen sulfide to form colored brownish precipitates of lead sulfide. Thus far, in order to detect leakage of H2S gas in industrial sectors, Pb(Ac)2 has been used as an indicator in the form of test papers with a detection limit only as low as 5 ppm. Diagnosis of halitosis by exhaled breath needs sensors able to detect down to 1 ppm of H2S gas. In this work, high surface area and porous Pb(Ac)2 anchored nanofibers (NFs) that overcome limitations of the conventional Pb(Ac)2-based H2S sensor are successfully achieved. First, lead(II) acetate, which melts at 75 °C, and polyacrylonitrile (PAN) polymer are mixed and stirred in dimethylformamide (DMF) solvent at 85 °C, enabling uniform dispersion of fine liquid droplets in the electrospinning solution. During the subsequent electrospinning, Pb(Ac)2 anchored NFs are obtained, providing an ideal nanostructure with high thermal stability against particle aggregation, numerous reactions sites, and enhanced diffusion of H2S into the three-dimensional (3D)-networked NF web. This newly obtained sensing material can detect down to 400 ppb of H2S at a relative humidity of 90%, exhibiting high potential feasibility as a high-performance colorimetric sensor platform for diagnosis of halitosis.

Herein, we incorporated dual biotemplates, i.e., cellulose nanocrystals (CNC) and apoferritin, into electrospinning solution to achieve three distinct benefits, i.e., (i) facile synthesis of a WO3 nanotube by utilizing the self-agglomerating nature of CNC in the core of as-spun nanofibers, (ii) effective sensitization by partial phase transition from WO3 to Na2W4O13 induced by interaction between sodium-doped CNC and WO3 during calcination, and (iii) uniform functionalization with monodispersive apoferritin-derived Pt catalytic nanoparticles (2.22 ± 0.42 nm). Interestingly, the sensitization effect of Na2W4O13 on WO3 resulted in highly selective H2S sensing characteristics against seven different interfering molecules. Furthermore, synergistic effects with a bioinspired Pt catalyst induced a remarkably enhanced H2S response (Rair/ Rgas = 203.5), unparalleled selectivity (Rair/ Rgas < 1.3 for the interfering molecules), and rapid response (<10 s)/recovery (<30 s) time at 1 ppm of H2S under 95% relative humidity level. This work paves the way for a new class of cosensitization routes to overcome critical shortcomings of SMO-based chemical sensors, thus providing a potential platform for diagnosis of halitosis.
