A randomized phase III prospective trial of bethanechol to prevent mucositis, candidiasis, and taste loss in patients with head and neck cancer undergoing radiotherapy: a secondary analysis.
(52/131)
The aim of this study was to determine the impact of bethanechol administration concomitant to radiotherapy (RT) on oral mucositis, candidiasis and taste loss. We performed a secondary analysis of a previously conducted prospective randomized trial which evaluated the effect of bethanechol on salivary gland dysfunction before, during, and after RT for head and neck cancer (HNC), in comparison to artificial saliva. Mucositis, candidiasis and taste loss were analyzed in 36 patients. Mucositis was scored using the World Health Organization (WHO) method; candidiasis was diagnosed by means of clinical examination, whereas taste loss was assessed by the patients' subjective report of absence of taste. No significant differences were observed between groups in relation to frequency and severity of mucositis or frequency of candidiasis and taste loss. In conclusion, bethanechol does not appear to reduce the incidence of mucositis, candidiasis, and taste loss when administered during RT. (+info)

Effects of oral care in Down syndrome children with obstructive sleep apnea.
(56/131)
Down syndrome (DS) children with sleep apnea often present with oral breathing associated with nasal obstruction. This causes the oral cavity and pharynx to become dry. We describe the treatment of three DS children with sleep apnea who were treated using products for oral dryness. Snoring disappeared after treatment in two of the children and apnea disappeared in all three. The symptoms of a reddened oral mucosa and coated tongue disappeared in all three DS children. Saliva pH testing demonstrated that the pH value increased in all of the children after treatment. These results indicate that oral care can improve the oral hygiene status of DS children, and that proper oral care can help prevent oral mucosal dryness and thereby reduce sleep apnea symptoms.
