Prevalence and Associations of Xerostomia in Older Adults in Southern Brazil

OBJECTIVES

This study investigated the prevalence and associations of xerostomia in older adults in southern Brazil.

METHODS

A cross-sectional study was carried out in Pelotas, Brazil, during 2014. A representative sample of the city's older adult population (60+) was selected. The dependent variable was self-reported feeling of dry mouth in the past 6 months. Covariates included socio-economic status, schooling, gender, age, tobacco and alcohol consumption, polypharmacy, hypertension, diabetes, arthritis, depression, dentition status and use of removable dental prostheses. Descriptive analysis was carried out, and Poisson regression was used to obtain prevalence ratios and 95% confidence intervals. Analyses used STATA 15.1.

RESULTS

Most of the 1451 participants were female (63.3%). The prevalence of xerostomia was 36.7% (95% CI 34.3-39.1). Adjusted analysis showed that xerostomia was significantly more common among females (PR 1.44, 95% CI 1.22-1.74), those with less schooling (PR 1.31, 95% CI 1.10-1.51), those exposed to polypharmacy (PR 1.22, 95% CI 1.05-1.37), people with arthritis (PR 1.42, 95% CI 1.23-1.61) and those with depression symptoms (PR 1.45, 95% CI 1.23-1.70).

CONCLUSION

Xerostomia is common among older adults. Health workers need to pay attention to its associated factors for early identification and promotion of appropriate interventions, particularly the rational use of medicines.

Periodontal disease in seropositive rheumatoid arthritis: scoping review of the epidemiological evidence

The link between periodontal disease (PD) and rheumatoid arthritis (RA) has been hypothesized to lie in the anti-cyclic citrullinated protein antibody (ACPA) molecules present in seropositive RA. This review aimed to discuss how RA and specifically ACPA-positive RA link to PD, and appraise the epidemiological evidence on the relationship between ACPA-positive RA and PD. Articles were searched following the PRISMA guideline across the MEDLINE, Web of Science, Scopus and Cochrane Library databases. A total of 21 articles met the inclusion criteria of reporting the epidemiological data on the different ACPA status of the subjects with RA and PD (or periodontitis) parameters. A discrepancy is noted in the epidemiological evidence on the difference in the prevalence and severity of PD between ACPA-positive and ACPA-negative RA patients. Although the link between RA and PD is mostly discussed in terms of ACPA, reports on the different manifestations of PD between the two RA subsets remains inconclusive.

Prevalence of signs of dysphagia and associated risk factors in geriatric patients admitted to an acute medical unit

BACKGROUND AND AIMS

Dysphagia is a prevalent disorder among the older persons. Despite this, signs of dysphagia often go unnoticed in hospital settings. This cross-sectional study aimed at investigating the prevalence of signs of dysphagia among patients aged 65 or older in a Danish acute care setting.

METHODS

We studied 334 patients aged 65 years or older admitted to the acute medical unit (AMU) at Aalborg University Hospital, Denmark. Signs of dysphagia were assessed using bedside screening tools including the Eating Assessment Tool (EAT-10), a 30 mL Water Swallowing Test (WST) and the Gugging Swallowing Screen tool (GUSS). Other risk factors were assessed using the Eastern Cooperative Oncology Group Performance Status (ECOG-PS), the Nutritional Risk Screening 2002 (NRS), and the Charlson's Comorbidity Index (CCI).

RESULTS

Signs of dysphagia were identified in 144 of 334 (43.1%) patients. Geriatric patients with signs of dysphagia were significantly older (79.5 years [74; 85] vs. 77 years [72; 84], p = 0.025) and had higher CCI scores (3 points [2; 4] vs. 2 points [1; 4], p = 0.001) than those with normal swallowing capacity. Furthermore, a multivariate logistic regression model found signs of dysphagia to be independently associated with nutritional risk (OR = 2.169, 95% CI 1.313-3.582, p = 0.002), cerebrovascular disease (OR = 2.209, 95% CI 1.235-3.953, p = 0.008), chronic pulmonary disease (OR = 2.276, 95% CI 1.338-3.871, p = 0.002) and rheumatic disease (OR = 2.268, 95% CI 1.099-4.683, p = 0.027). Age was not independently associated with signs of dysphagia among the geriatric patients.

CONCLUSION

Signs of dysphagia were common among patients aged 65 or older in the acute care setting. Signs of dysphagia were associated with nutritional risk, higher CCI scores and specific comorbidities. These findings could indicate a need for systematic screening for dysphagia in acute geriatric patients, yet further investigation is needed to assess clinical outcomes associated with dysphagia within this population.

Temporomandibular Disorders and Oral Features in Systemic Lupus Erythematosus Patients: An Observational Study of Symptoms and Signs

Aims: Systemic Lupus Erythematosus (SLE) is a connective tissue disease characterized by a wide range of pleomorphic pictures, including mucocutaneous, renal, musculoskeletal and neurological symptoms. It involves oral tissues, with hyposalivation, tooth decay, gingivitis, angular cheilitis, ulcers and glossitis. Temporomandibular disorders represent a heterogeneous group of inflammatory or degenerative diseases of the stomatognatic system, with algic and/or dysfunctional clinical features involving temporomandibular joint (TMJ) and related masticatory muscles. The aim of this study was to investigate the prevalence of oral manifestations and temporomandibular disorders (TMD) in SLE patients (Lp) compared with a control group. Methods: Fifty-five patients (9 men and 46 women) with diagnosed Lupus were recruited in the study group. A randomly selected group of 55 patients, matched by sex and age, served as control group. The examination for TMD symptoms and signs was based on the standardized Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) through a questionnaire and clinical examination. Results: Lupus patients complained more frequently (95.8%) of oral and TMJ symptoms (dysgeusia, stomatodynia, masticatory muscle pain during function, neck and shoulder muscles pain and presence of tinnitus) but only xerostomia (χ2=4,1548 p=0,0415), temple headache (χ2=4,4542 p=0,035) and the sensation of a stuck jaw (Mid-p-test p=0,043) were significant. About signs, cheilitis (p=0,0284) oral ulcers (χ2=4,0104 p=0,045) and fissured tongue are significantly more frequent in study group. The salivary flow was significantly decreased in the study group respect to the control one (p<0.0001). As regard to the oral kinematics, restricted movements (RM) in protrusion and left lateral movement were significantly different between study group and controls. In particular, 85,2% of Lp showed limited protrusion versus 56,4% of controls (χ2= 10,91 p<0,001); 59,3% of Lp had also a limitation during left lateral movement versus 47,3% of controls (T=2,225 p=0,0282). About bruxism, only the indentations on the lateral edges of the tongue were found in Lp group (72,7%), with a significant difference respect to controls (χ2=7,37 p=0,007). Conclusions: While masticatory muscles have an overlapping behavior in both groups, the findings collected show a more severe TMJ kinematic impairment in Lp than in controls, with protrusion and left lateral movements significantly different. In addition, a remarkable reduction of salivary flow has been detected in Lp compared to controls. In conclusion, this autoimmune disease seems to play a role in oral manifestations and TMJ disorders, causing an increase in orofacial pain and an altered chewing function.

[Oral health in patients with systemic sclerosis]

The aim of this study was to conduct literature review about oral manifestations of scleroderma. Systemic sclerosis is a multisystem autoimmune disorder characterized by widespread fibrosis, vascular alterations and inflammation. Systemic sclerosis mainly affects people in age from 30 to 50 years, but the onset of disease can occur in any age. The disturbance of microcirculation with the activation and proliferation of endothelium and smooth muscle cells plays an important role in pathogenesis of sclerodrma. These changes lead to sclerosis and fibrosis of various part in human body. Orofacial manifestations of scleroderma include: reduced mouth opening, widening of periodontal ligament, teleangiectasia, bone lesions. Systemic scleroderma is often accompanied by Sjogren's syndrome. Oral manifestations of Sjogren's syndrome are recurrent parotitis, angular cheilitis, xerostomia and multiple caries. Sjogren's syndrome leads to negative impact on patients health and mental status. Orofacial manifestations of systemic sclerosis are still poorly known, that is why more researches should be made to improve dental treatment of patients with systemic sclerosis.

The Prevalence of Oropharyngeal Dysphagia in Adults Presenting with Temporomandibular Disorders Associated with Rheumatoid Arthritis: A Systematic Review and Meta-analysis

Temporomandibular disorders (TMDs) are the most frequent non-dental orofacial pain disorders and may be associated with rheumatoid arthritis (RA), resulting in oropharyngeal dysphagia (OD). However, clinicians' understanding of involvement with OD caused by RA-related TMDs is limited and the methodological quality of research in this field has been criticised. Therefore, the aim of this study was to systematically review the prevalence of oral preparatory and oral stage signs and symptoms of OD in adults presenting with TMDs associated with RA. A systematic review of the literature was completed. The following electronic databases were searched from inception to February 2016, with no date/language restriction: EMBASE, PubMed, CINAHL, Web of Science, Elsevier Scopus, Science Direct, AMED, The Cochrane Database of Systematic Reviews, and ProQuest Dissertations and Theses A & I. Grey literature and reference lists of the included studies were also searched. Studies reporting the frequency of OD in adults presenting with TMD and RA were included. Study eligibility and quality were assessed by three independent reviewers. Methodological quality was assessed using the Down's and Black tool. The search yielded 19 eligible studies. Typical difficulties experienced by RA patients included impaired swallowing (24.63%), impaired masticatory ability (30.69%), masticatory pain (35.58%), and masticatory fatigue (21.26%). No eligible studies reported figures relating to the prevalence of weight loss. Eligible studies were deemed on average to be of moderate quality. Study limitations included the small number of studies which met the inclusion criteria and the limited amount of studies utilising objective assessments. Valid and reliable prospective research is urgently required to address the assessment and treatment of swallowing difficulties in RA as TMJ involvement may produce signs and symptoms of OD.
