Chamomile Gel versus Urea Cream to Prevent Acute Radiation Dermatitis in Head and Neck Cancer Patients: Results from a Preliminary Clinical Trial.

We assessed safety and potential efficacy of a chamomile gel compared with urea cream to prevent acute radiation dermatitis in head and neck cancer patients. We assessed safety and potential efficacy of the chamomile gel in escalating concentrations of 2.50%, 5.00% and 8.35% of chamomile. Concentration of 8.35% was chosen for a randomized trial comparing chamomile gel (8.35%) with urea cream (n = 24 per group), for potential efficacy to delay or prevent radiation dermatitis in these patients. Preliminary results demonstrate a delayed onset of dermatitis, with onset of Grade 2 dermatitis at 5.1 (1.3) weeks in the chamomile group and 4.5 (1.3) weeks in the urea group (effect size of 0.46). Itching, burning and hyperpigmentation were more frequently reported in the urea group. Results indicates a potential efficacy of the chamomile gel. Further studies are needed to confirm the effect of the chamomile gel in reducing or delaying the occurrence of radiation dermatitis.

Effectiveness of topical interventions to prevent or treat intravenous therapy-related phlebitis: A systematic review.

AIMS AND OBJECTIVES: To evaluate the effectiveness of topical interventions in the prevention or treatment of intravenous therapy-related phlebitis. BACKGROUND: Phlebitis is a severe inflammatory reaction that can be caused by intravenous therapy with hyperosmolar drugs. Although a variety of interventions are performed in several different countries, the most efficient method is yet to be established. DESIGN: A systematic review of randomised controlled trials (RCTs) was conducted. METHODS: Following the PRISMA checklist, we conducted a literature search using seven different databases using an individual strategy adapted for each. Studies in which any topical intervention was applied to prevent or treat intravenous therapy-related phlebitis which were published between 1998 and 2019 were analysed. RESULTS: Data were collected of 13 RCTs, which in total collected data from 2,015 patients during hospital treatments with different types of intravenous therapies, such as fluid replacement, antibiotics, chemotherapy and antiarrhythmic drugs. The effectiveness of different topical interventions such as the application of nonsteroidal anti-inflammatory drugs, Sesame indicum oil, heparin sodium formulations, Chamomilla recutita tea and ointment, and Rosmarinus officinalis ointment were identified. RELEVANCE TO CLINICAL PRACTICE: Although the studies suggest a potential to use phytotherapy agents as topical interventions, pharmaceutical preparations, main substrate, and pharmaceutical or phytotherapeutic origins are very different between studies. There are insufficient data to build a solid conclusion that lead us to recommend a specific topical intervention in the prevention or treatment of intravenous therapy-related phlebitis.
