Xerostomia, the perception of general and oral health and health risk behaviours in people over 65 years of age.

BACKGROUND: This study investigated the association between xerostomia and health risk behaviours, general and oral health and quality of life. METHODS: A cross-sectional study involving 800 adults over 65 years of age residing in Spain using a computer-assisted telephone questionnaire. The severity of xerostomia was assessed through the Xerostomia Inventory (XI). Both univariate and adjusted multinomial logistic regression were used to determine the risk (OR) of xerostomia. RESULTS: The sample comprised of 492 females (61.5%) and 308 males, with a mean age of 73.7 ± 5.8 years. Some, 30.7% had xerostomia: 25.6% mild, 4.8% moderate and 0.3% severe, the majority being female (34.8% vs 24%; p = 0.003). The mean XI was 24.6 ± 6.3 (95% CI 19.2-24.8) for those with poor health, whereas it was 17.4 ± 6.3 (95%CI 16.1-18.6) in those reporting very good health (p < 0.001). This difference was also observed in terms of oral health, with the XI mean recorded as 14.7 ± 10.7 for very poor oral health and 6.4 ± 5.4 for those with very good health (p = 0.002). Logistic regression showed that the highest OR for xerostomia was observed among adults with poor general health (2.81; 95%CI 1.8-4.3; p < 0.001) and for adjusted model the OR was still significant (2.18; 95%CI 1.4-3.4; p = 0.001). Those who needed help with household chores had 2.16 higher OR (95%CI 1.4-3.4; p = 0.001) and 1.69 (95%CI 1.1-2.7; p = 0.03) in the adjusted model. Females had a higher risk of suffering from xerostomia than males. CONCLUSION: The strong association between xerostomia and the general and oral health status of older adults justifies the need for early assessment and regular follow-up.

Oral leiomyosarcoma: the importance of early diagnosis.

OBJECTIVE: Present a case clinic of leimyosarcoma. BACKGROUND: Leiomyosarcomas (LMSs) are malignant mesenchymal tumours of smooth muscle differentiation that grow rapidly and whose prognosis is dependent upon the tumour site and disease stage. Their location in the oral cavity is considered extremely rare due to the lack of smooth muscle tissue in that area. MATERIALS AND METHODS: We present an LMSs case of the buccal mucosa in an elderly patient patient with a follow-up of 4 years. CONCLUSION: Early diagnosis and treatment play a key role in a better prognosis.

Malignant transformation of oral lichen planus by a chronic inflammatory process. Use of topical corticosteroids to prevent this progression?

BACKGROUND: Oral lichen planus is a potentially malignant disorder with a capacity, although low, for malignant transformation. Of all the factors related to the process of malignant transformation, it is believed that the chronic inflammatory process plays a key role in the development of oral cancer. This inflammatory process is capable of providing a microenvironment based on different inflammatory cells and molecules that affect cellular growth, proliferation and differentiation. OBJECTIVES: The objectives of our study are: to review the available evidence about the possible relationship between the chronic inflammatory process present in oral lichen planus and its malignant transformation, to discuss the potential therapeutic implications derived from this relationship and to study the role that topical corticosteroids play in the control of oral lichen planus inflammation and its possible progression to malignant transformation. CONCLUSION: The maintenance of a minimum dose of topical corticosteroids could prevent the inflammatory progression of oral lichen planus to oral cancer.
