Radiation-induced trismus has a significant impact on the quality of life of patients receiving radiotherapy for head and neck cancers. Pentoxifylline has immunomodulatory activities that downregulate certain cytokines that have been implicated as mediators of fibrogenic reactions after radiation. A pilot study was therefore conducted to evaluate the efficacy of pentoxifylline in the treatment of radiation-induced trismus. Twenty patients with severe trismus (dental gap < or = 25 mm) after receiving radiotherapy for nasopharyngeal carcinoma were enrolled onto the study. Four patients were excluded from analysis because of poor drug compliance. The remaining 16 evaluable patients completed an 8-week course of pentoxifylline at a dose of 400 mg two to three times daily. Changes in dental gap were recorded by measuring the distance between left upper and lower incisor before and after treatment. At the end of treatment, 10 patients had a measured increase in dental gap ranging from 2 to 25 mm. Six patients had an increment of 5 mm or more. The mean dental gap before treatment was 12.5 mm compared with 16.5 mm at the end of treatment (p = 0.023). The mean difference in dental gap was 4 mm, with a 95% confidence interval of 0.6 to 7.4 mm. The drug pentoxifylline appears to exert a modest therapeutic effect in patients with radiation-induced trismus, although our findings need to be confirmed by a randomized placebo-controlled study. While awaiting more evidence from clinical studies, a therapeutic trial of pentoxifylline is worth considering in patients experiencing radiation-induced trismus.

Flunitrazepam in 2-mg and 4-mg doses was compared with flurazepam 30 mg and nitrazepam 10 mg for hypnotic efficacy in a double-blind, multiple cross-over trial involving 41 psychiatric in-patients. In the vast majority of comparisons involving a number of sleep parameters differences did not reach significance level. Flunitrazepam 4 mg tended to produce the shortest latency time and the longest duration of sleep but also the most side-effects. Nitrazepam 10 mg appeared to have a slight advantage over the other drugs in terms of patient preference. For severe sleep disturbance flunitrazepam 2 mg tended to be the most satisfactory drug in terms of efficacy and paucity of side-effects.

Family psychoeducation (FPE) has been recommended as a major component in the treatment of psychosis. Many previous studies have implemented an intensive program design that often only emphasized improvements in patients’ illness outcomes but the benefits for caregivers were limited. There have been calls for a time-limited but cost-effective FPE program to mitigate the looming reality of the suffering of people with psychosis and their families. A Brief Mindfulness-Based Family Psychoeducation for psychosis program is developed to reduce caregivers’ burden and promote young adult’s recovery. A randomized controlled trial will be conducted to compare this intervention with an ordinary FPE intervention. Both arms will involve six sessions, with a total contact time of 12 h. 300 caregivers of young adults who have experienced first episode psychosis within last 3 years will be recruited. Program effectiveness will be assessed by comparing outcomes measuring the caregivers’ burden, mental health symptoms, positive well-being, and the young adult’s mental health symptoms during the study and at 9-month post-randomization. The role of expressed emotions, interpersonal mindfulness, and non-attachment in mediating these outcomes will be explored. An additional qualitative approach Photovoice is selected to explore the complex family experiences and the benefits of mindfulness from the caregivers’ personal perspectives.Trial Registration: The trial is registered with the United States Clinical Trials Registry (ClinicalTrials.gov): NCT03688009.
