Wernicke’s encephalopathy, an acute neuropsychiatric syndrome caused by thiamine (vitamin B1 ) deficiency, is associated with serious clinical disease and can be fatal. It has rarely been reported in infants and children. We report a case of a 3-year-old girl with Wernicke’s encephalopathy. The patient’s diet had been severely unbalanced since the age of 2 years, and for about a month prior to admission to our hospital had consisted almost exclusively of polished white rice and noodles. Her clinical symptoms supported thiamine deficiency-related neuropathy. Brain MRI findings revealed abnormalities consistent with pediatric Wernicke’s encephalopathy with involvement of the putamen. The diagnosis prompted thiamine replacement therapy, to which the patient showed an excellent response.

Purpose: The purpose of this study is to evaluate hangeshashinto rinse for oral discomfort in terminally-ill cancer patients and to compare the effectiveness of hangeshashinto rinse with or without honey rinse. Methods: Patients with oral discomfort were randomized to receive either hangeshashinto rinse or hangeshashinto with honey rinse as first-line treatment. Patients performed oral rinse three to five times a day for 2 weeks. Further, oral wetness, halitosis, oral mucositis, mouth discomfort, compliance of rinse were then evaluated before and after the intervention. Results: 144 patients were enrolled during this period and 22 patients completed the study (hangeshashinto 13 / hangeshashinto with honey 9). After the intervention, oral wetness was improved, and end-tidal concentration of hydrogen sulfide was decreased in both cases. Although there was no statistically significant difference, oral discomfort by subjective and objective evaluations, also and symptom of oral mucositis were improved. Other volatile sulfur compounds decreased. Frequency of rinsing between groups receiving hangeshashinto or hangeshashinto with honey did not differ, however, the acceptability was slightly better in the honey combination group. Conclusion: Both hangeshashinto rinse and hangeshashinto with honey rinse reduced end-tidal concentration of hydrogen sulfide and improved oral wetness. Oral rinse by hangeshashinto or hangeshashinto with honey may be effective for oral discomfort in terminally-ill cancer patients.
