In intermediate- and high-risk prostate cancer patients, focal dose escalation integrated with standard EBRT did not result in an increase in GU and GI toxicity when compared to the standard treatment up to two years after treatment. This suggests that the described focal dose escalation technique is safe and feasible.
The evidence for the benefit of intranasal corticosteroids on symptom relief in adult patients with recurrent acute rhinosinusitis is rather limited (ie, 3 trials are available; the best evidence is derived from 1 low risk of bias trial providing moderate directness of evidence that intranasal corticosteroids may speed up relief of symptoms in patients with recurrent acute rhinosinusitis). A large methodologically rigorous randomized trial in antibiotic-naïve patients is needed to provide a more definite recommendation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
