Abstract
BACKGROUND Sinonasal carcinomas (SNC) constitute about 3% of all head and neck carcinomas, squamous cell carcinoma being the most common histologic subtype. Some geographical patterns in incidence are observed, as occupational exposure to wood dust is associated with intestinal-type adenocarcinoma (ITAC). AIMS This study aims to describe the prevalence and characteristics of sinonasal ITAC cases in a region of northern Portugal with a robust wood industry. METHODS A retrospective study of all sinonasal malignancies diagnosed over 5 years, in a tertiary hospital, primarily focused on ITAC subtypes. Data on sociodemographic and clinical variables were collected through electronic medical records and telephonic assessments. RESULTS Of all 33 cases, 85% were ITAC. ITAC predominantly affected males (96%) with a mean age of 66.2 years. Most patients diagnosed with sinonasal ITAC had occupational wood dust exposure (96%), particularly to hardwoods. Initial symptoms included unilateral nasal obstruction (75%) and epistaxis (71%). Despite a median time of 3 months from symptoms to consultation, 50% presented at an advanced stage, with a 29% mortality rate. CONCLUSIONS Sinonasal ITAC is an occupational hazard of woodworkers and represents the vast majority of SNC in the region. This study advocates for targeted community interventions, emphasizing occupational safety measures and healthcare awareness to reduce morbimortality associated with this occupational cancer.

Chlorhexidine Improves Hygiene Reducing Oral Polymorphonuclear Leukocytes with Antimicrobial Effects at Distinct Microenvironments amongst Subjects Stratified by Health Status. Antibiotics (Basel) 2022; 11:antibiotics11050603. [PMID: 35625248 PMCID: PMC9137765 DOI: 10.3390/antibiotics11050603] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/08/2022] [Revised: 04/26/2022] [Accepted: 04/26/2022] [Indexed: 11/30/2022] Open
Abstract
Oral conditions such as gingivitis and oral malodor are commonly reported globally. Objective: This investigation clinically stratified subjects to healthy, malodor and gingivitis groups and enumerated oral polymorphonuclear leukocytes (PMN) as a measure of inflammation prior to and after rinsing with a chlorhexidine (CHX) mouthwash. The study also assessed clinical outcomes (dental plaque and gingival bleeding indices), malodor (halimeter scores, organoleptic and tongue coat index and microbiological parameters (anaerobic and malodor organisms of dental plaque, tongue surface and saliva) for a comprehensive assessment of the oral inflammatory burden. Methods: Consenting adults were stratified into control (n = 17), gingivitis (n = 19) and halitosis (n = 17) groups based on clinical criteria. At baseline, oral samples were examined for PMN in addition to microbiological analysis of dental plaque, saliva and tongue scrapings for anaerobic and malodor bacteria. Subjects were issued a commercially available fluoride toothpaste and a chlorhexidine mouthwash for two-week use prior to post-treatment assessments identical to baseline. Results: At baseline, PMN were lowest in the control that increased amongst the halitosis subjects, with the gingivitis group registering the highest levels (p < 0.05) with these outcomes corresponding with clinical parameters (p < 0.05). CHX use improved outcomes with a 56−61% reduction in PMN with significant differences between groups (p < 0.05). Dental plaque and bleeding indices were lower by 57−78% with oral malodor, demonstrating reductions of 33−59% (p < 0.05). Significant reductions in anaerobic and malodor organisms ranging from 78−96% and 76−94%, respectively, were noted after CHX use (p < 0.05). Conclusions: At study enrollment, PMN scores were lowest in healthy subjects, with increasing numbers amongst halitosis followed by gingivitis. Amongst all subject groups, CHX use significantly reduced oral PMN and corroborated with corresponding decreases in clinical, malodor and bacterial outcomes. Together, these results demonstrate the significant reductions in the oral inflammatory burden following CHX use.

Airway inflammatory profile among cleaning workers from different workplaces. BMC Pulm Med 2022; 22:170. [PMID: 35488256 PMCID: PMC9052628 DOI: 10.1186/s12890-022-01949-5] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2021] [Accepted: 04/11/2022] [Indexed: 01/01/2023] Open
Abstract
Background Cleaning workers represent a significant proportion of the active population worldwide, with poor remuneration, particularly in developing countries. Despite this, they remain a relatively poorly studied occupational group. They are constantly exposed to agents that can cause symptoms and respiratory problems. This study aimed to evaluate upper airway inflammation in professional cleaning workers in three different occupational settings by comparing nasal cytology inflammation and clinical profiles. Methods We performed a cross-sectional study on the prevalence of upper airway inflammation and symptoms of asthma/rhinitis related to cleaning work, according to workplace. A total of 167 participants were divided into four groups: hospital, university, housekeeper and control. A nasal swab was collected for upper airway inflammation evaluation. Clinical profiles and respiratory symptom employee evaluations were performed using specific questionnaires (European Community Respiratory Health Survey—ECRS and the International Study of Asthma and Allergies in Childhood—ISAAC). Results Cleaning workers showed increased neutrophils and lymphocytes; the hospital and university groups showed increased macrophages compared to the housekeeper and control groups. The hospital and housekeeper groups showed increased eosinophils when they performed cleaning services for up to one year and reported having more asthma symptoms than the control group. Cleaning workers showed increased rhinitis symptoms. The university group showed increased rhinitis symptoms aggravated by the workplace compared with the hospital and housekeeper groups. Cleaning workers showed an increased affirmative response when directly asked about rhinitis symptoms compared to the control group. Conclusions Cleaning workers showed airway inflammation, asthma symptoms and rhinitis, regardless of the occupational environment to which they were exposed, as well as showed increased rhinitis and asthma symptoms. Hospital cleaning workers showed increased macrophages, lymphocytes and eosinophils compared to the others. The length of time spent performing cleaning work was not related to nasal inflammation or respiratory symptoms in this population. However, there were differences in workplaces. Registered on ClinicalTrials.gov. Trial registration number: NCT03311048. Registration date: 10.16.2017. Retrospectively registered.

Abstract
This investigation evaluated clinical parameters and the levels of polymorphonuclear leukocytes [PMN] collected in an oral rinse amongst subjects who refrained from dental hygiene for a period of 12 days. Methods Study enrolled consenting adults and assigned to a non-prophy group [n = 16] and a separate prophy group [n = 27]. Both groups underwent clinical evaluations and sampling for PMN at baseline and on days 3,6,9 and 12 of study initiation. The prophy group underwent supragingival prophylaxis at the conclusion of the no-hygiene phase and recalled for a final clinical evaluation and PMN assessment 1 week later. Results Progressive increases in oral PMN were noted due to abstinence from oral hygiene (p < 0.05). Subjects registered PMN increases ranging from 20% recorded three days following abstinence of hygiene to the highest value of 298% at the 12-day evaluation (p < 0.05). One week after prophylaxis, average PMN scores were 22% lower than baseline (p < 0.05). Abstinence from dental hygiene led to progressive increases in clinical parameters for dental plaque, gingival inflammation and bleeding. Dental plaque, gingival index and gingival bleeding scores recorded increases of 59%, 64% and 126% respectively at the conclusion of the no-hygiene phase. Prophylaxis resulted in marked reductions in all clinical parameters. Conclusions Abstinence from dental hygiene corresponded with increasing scores for dental plaque, gingival inflammation and bleeding in conjunction with increasing oral PMN. These effects were irrespective of age or gender and were reversed by supragingival prophylaxis.

Abstract
OBJECTIVE Assessment of the nasal cytology in revealing early nasal mucosa alteration of workers exposed to benzene. METHODS Nasal cytology was compared among non-exposed and exposed workers to benzene. A comparison of the two groups was performed considering rhino-cytological features. RESULTS In the exposed group neutrophils count range was 14 to 70, compared to 2 to 5 in control group. Ciliated cells ratio range was respectively 0.28 to 2.8 and 0.25 to 0.31. In subjects exposed to benzene >10 years, nasal mucosa showed an inflammatory status and an ongoing mucipar metaplasia, defined by an alteration of mucipar/ciliated cells ratio. CONCLUSIONS Nasal cytology may be a useful research tool for the health surveillance of workers exposed to benzene and may be applied to study the effects of other upper airways chemicals irritants.

Abstract
OBJECTIVE To assess the effects of workplace exposure to hardwood dust on lung function and determine a prevalence of respiratory symptoms among wood workers. STUDY DESIGN Cross-sectional observational study. SETTING Tertiary referral center. SUBJECTS AND METHODS Two hundred seventy-six, non-smoker male wood workers and equal number of non-smoker male office workers, referred to pulmonology clinic included in this study. Evaluation of study participants included completion of a questionnaire regarding respiratory symptoms and baseline spirometry was measured according to the actual recommendations. RESULTS Respiratory symptoms including cough, phlegm, chest tightness, and wheezing were significantly higher in wood workers than office workers (40.2% versus 29.3% for cough, p = 0.0073; 40.6% versus 23.6% for phlegm, p<0.0001; 38.0% versus 23.1% for chest tightness, p = 0.0001; 25.3% versus 14.5% for wheezing, p = 0.0014). No statistically significant differences were observed for Dyspnea, and upper respiratory tract symptoms among wood workers compared to office workers. While wood workers were more likely to require spirometry test than office workers (21.4% versus 5.4%, p<0.001) the obstructive changes were more prevalent on spirometry test in wood workers (71.4% obstructive pattern versus 28.6% restrictive pattern). Spirometry test revealed the mean values of FEV1 and FEV1/FVC ratio were significantly lower in the wood workers, compared to their mean values in the control group. CONCLUSION Respiratory symptoms associated with work, are more prevalent among wood workers than office workers. Our data revealed that workplace exposure to hardwood dust may compromise respiratory function, indicating the importance and the need for optimizing preventive measures in workplace to protect the respiratory health among exposed workers. Obstructive changes on pulmonary function test is a dominant pathologic pattern in pulmonary function test among wood workers. Further investigation is required by current available tools such as nasal cytology to detect influence of wood dust exposure on the upper respiratory airway.

Abstract
OBJECTIVES The aim of the present study was to measure nasal mucociliary clearance (NMC) time in the patients with MS and to compare the findings with healthy population. METHODS Totally 97 individuals including 47 patients with relapsing-remitting multiple sclerosis and 50 healthy volunteers were enrolled into the study. Saccharin clearance test was performed on both groups and NMC time was measured. Data analysis was performed by SPSS version 24.0 statistics program (SPSS Inc., Chicago, Illinois, USA). Statistical tests were interpreted at p < 0.05 significance level. RESULTS The NMC time averages in MS patients and healthy control group were 12.43 ± 4.05 min and 8.14 ± 2.87 min, respectively; the difference between the groups was significant (p < 0.001). There was a statistically strong association between NMC time values and Expanded Disability Status Scale (EDSS) values in MS patients (r = 0.817, p < 0.001). CONCLUSION We found nasal mucociliary transport time longer in MS patients than healthy population in the present study. To the best of our knowledge, there is not any study conducted about this topic in the literature. We believe that our findings would shed a light on further studies.

Abstract
Background The nasal cycle is the spontaneous congestion and decongestion of nasal mucosa that happens during the day. Classically, 4 types of nasal cycle patterns have been described: (1) classic, (2) parallel, (3) irregular, and (4) acyclic. Hypothalamus has been considered as the central regulator even if several external factors may influence its activity. Objective The aim of the study was to evaluate the presence of a correlation between nasal cycle pattern, nasal cytology and nasal symptoms. Methods Thirty healthy volunteers have been enrolled in the study. All subjects completed a Sino-Nasal Outcome Test-22 questionnaire and a Visual Analog Scale (VAS) for nasal obstruction. The nasal cycle was studied by means of peak nasal inspiratory flow. Nasal cytology has been used to evaluate the presence of local nasal inflammation. Results Nineteen subjects showed a parallel nasal cycle pattern, while 11 showed a regular one. A parallel pattern was present in 60% of asymptomatic subjects and in 67% of the symptomatic one ( P = 1). VAS for nasal obstruction did not show a significant difference between the 2 patterns of the nasal cycle ( P = .398). Seventeen subjects had a normal rhinocytogram, while 13 volunteers showed a neutrophilic rhinitis; 53.8% of the subjects with a neutrophilic rhinitis showed a parallel pattern, while the remaining 46.2% had a regular one. In the case of a normal cytology, 70.6% of the volunteers had a parallel pattern and 29.4% had a regular one. Differences between the 2 groups were not statistically significant ( P = .575). Conclusion Rhinitis with neutrophils seems to not influence the nasal cycle pattern. Based on the present results, the pattern of nasal cycle does not influence subjective nasal obstruction sensation.

Abstract
Background Workers in pathology and anatomy laboratories may be exposed to formaldehyde. An evaluation of the early effects of this substance is, therefore, paramount. This preliminary study was conducted to evaluate if nasal cytology could be used as a tool to detect changes in nasal mucosa in workers exposed to formaldehyde. Aims To assess whether nasal cytology was able to reveal any alteration of nasal mucosa in workers exposed to formaldehyde compared to unexposed subjects, and to ascertain whether a specific pattern of alterations correlated with years of exposure in order to evaluate long-term occupational exposure effects. Methods The study included a group of workers exposed to formaldehyde and a group of non-exposed workers. All subjects underwent clinical examination, followed by nasal cytology. Pathological indices from each rhinocytograms were compared between the two groups. Results Nasal cytology revealed a chronic inflammatory non-allergic condition in the exposed group. Qualitative analysis of data distribution of neutrophils and mucous-secreting/ciliated cells ratio showed data clustering with a cut-off set at 15 years of exposure. The mean formaldehyde concentrations ranged from <0.04 to 0.15 parts per million (ppm). The maximum levels of formaldehyde concentrations ranged from 0.2 to 0.67 ppm. Conclusions Our data indicate that nasal cytology may be a promising tool for the health surveillance of workers exposed to formaldehyde and may also represent a useful research tool for the study of the health effects of other chemicals irritants for the upper airways.

Abstract
Aim. To investigate the role of dental malocclusion treatment in the outcomes of Recurrent Acute Otitis Media (RAOM). Materials and Methods. The clinical outcome (number of acute recurrences in 12 months) of 61 consecutive children treated medically for RAOM was analysed. Children underwent an odontostomatologic evaluation, a fiberoptic endoscopy, and skin-prick tests. Results. 32 children (group A) were diagnosed with dental malocclusion and treated with a mandibular repositioning plate. Dental malocclusion was ruled out in the other 29 patients with RAOM, and they were used as controls (group B). The two groups were homogeneous in terms of sex, exposure to RAOM risk factors, skin test results, and adenoid hypertrophy, while age was significantly higher in group A. Age, sex, exposure to RAOM risk factors, adenoid hypertrophy, and skin test results were not associated with RAOM outcome. Children in group A treated for dental malocclusion were strongly associated with a lower number of acute episode recurrences at both univariate (p < 0.0001) and multivariate analysis (p = 0.001). Conclusions. RAOM showed better outcomes in children with dental malocclusion wearing a mandibular repositioning device. Dental malocclusion in children with RAOM may play a role in the pathogenesis of Eustachian tube dysfunction.
