Purpose: Evaluation of the efficacy and safety of sublingual drug administration in palliative care patients lacking the ability to swallow as well as other drug administration routes. Methods: Buprenorphine, 0.1∼0.2mg/dose (n=15) and fentanyl, 0.05∼0.2mg/dose (n=26) were administered sublingually for cancer pain, and midazolam, 0.1mg/kg (n=16) for insomnia respectively. Results: The three drugs were all rapidly absorbed by the oral cavity and showed efficacy in about 90% of patients. No adverse events were observed other than drowsiness, nausea and over production of sputum in patients suffering from dysphagia. Conclusion: Sublingual administration is a viable alternative for maintaining the quality of life of patients not accessible through conventional administration routes in the palliative setting.

BACKGROUND: We aimed to examine the association of exposure to environmental tobacco smoke with dental caries among preschool children. Exposure to environmental tobacco smoke was assessed in terms of urinary cotinine concentrations and pack-years of exposure to smoking by parents and other family members at home. METHODS: This cross-sectional study included 405 preschool children aged 3-6 years from two preschools in Japan in 2006. Information on the smoking habits of family members living with the child was obtained from parent-administered questionnaires. Dental examination was conducted to assess dental caries, that is, decayed and/or filled teeth. Urinary cotinine levels were measured using first-void morning urine samples. RESULTS: Overall, 31.1% of the children had dental caries, and 29.5% had decayed teeth. Exposure to current maternal and paternal smoking was positively associated with the presence of dental caries after controlling for covariates. More than three pack-years of exposure to maternal smoking and more than five pack-years of exposure to smoking by all family members were significantly associated with the presence of dental caries as compared with no exposure (odds ratio [OR] = 5.55, 95% confidence interval [CI] = 2.17-14.22, P for trend < 0.001 and OR = 2.00, 95% CI = 1.12-3.58, P for trend = 0.004, respectively). These exposure variables were similarly associated with the presence of decayed teeth (OR = 2.92, 95% CI = 1.23-6.96, P for trend = 0.01 and OR = 1.75, 95% CI = 0.96-3.20, P for trend = 0.03, respectively). As compared with lowest tertile of the urinary cotinine level, the highest tertile of the urinary cotinine level was significantly associated with the presence of dental caries as well as decayed teeth; the ORs for the highest vs. lowest tertile of urinary cotinine levels were 3.10 (95% CI = 1.71-5.63, P for trend = 0.012) and 2.02 (95% CI = 1.10-3.70, P for trend = 0.10), respectively. CONCLUSIONS These data suggest that exposure to tobacco smoke may have a dose-dependent influence on the development of caries.
