ABSTRACT
Background: Radiation-induced mucositis and dermatitis are severe side effects and compromise the health of the head-and-neck cancer patient undergoing treatment. Zinc supplementation during the course of the treatment is shown to have protective effects against both radiation-induced mucositis and dermatitis. The aim of this study was to understand whether the level of serum zinc has an effect on the development of mucositis and dermatitis. Materials and Methods: This was noninterventional study where the levels of serum zinc were ascertained before the start of treatment by spectrophotometric methods. The patients were treated every day with no more than one fraction of 2 Gy per day, five times a week without any intended gaps for a planned target dose of 60-70 Gy (6-7 consecutive weeks). The patients were assessed for radiation-induced dermatitis and mucositis in accordance with the standard guidelines. The association between the levels of serum zinc with the development of different grades of mucositis and dermatitis (on the day of development) was ascertained using the Pearson correlation coefficient (r). A statistical value of P < 0.05 was considered to be statistically significant. Results: A total of 52 consecutive patients satisfying the inclusion criteria were enrolled. The results indicate that serum zinc levels showed a significant correlation (r = 0.29; P < 0.038) for Grade 1, while it was insignificant for Grades 2 and 3. For dermatitis, a significant correlation for all the grades (Grade 1 [r = 0.28; P < 0.043]; Grade 2 [r = 0.39; P < 0.006]; and Grade 3 [r = 0.49; P < 0.047]) was observed. Conclusions: For the first time, the results of this pilot study indicate that the serum level of zinc had an inverse association with the early development of mucositis and dermatitis, with better effects seen in dermatitis where it was also effective in Grades 2 and 3.

Viscum album, an infrequently used antihypertensive in homeopathy, is evaluated by 1-group pretest-posttest model in primary hypertension. The drug was administered for 12 weeks at a dosage of 10 drops 3 times a day. Using paired t test, a significant drop in blood pressure (P < .0001) and serum triglyceride (P < .0001) was observed in the treatment group. This dual effect of Viscum album shows promise in optimizing therapy for primary hypertension.
