Excessive axillary hyperhidrosis is a socially embarrassing condition which severely reduces quality of life and may result in psychological disturbance. Available treatment strategies do not resolve the problem in all cases. Intracutaneous injections of botulinum A toxin have been shown to be effective in patients with local sweating disorders. We performed a randomized, double-blind, within-group comparison in 13 individuals (nine women and four men) with severe axillary hyperhidrosis resistant to conventional treatment, to study the effect of intracutaneous injections of botulinum toxin on sweating. A total dose of 200 mouse units of botulinum A toxin (Dysport(R)) was injected into six different sites in one axilla, whereas the other was injected with sterile saline. Objective quantification of sweat production was performed using digitized ninhydrin-stained sheets. Three weeks after treatment, the mean difference in ninhydrin staining between botulinum-treated and placebo-treated axillae was -34.5% (P < 0.001), after 8 weeks -36.9% (P < 0.001) and after 13 weeks -28.4% (P < 0.001). Subjective rating of sweat production was evaluated on a visual analogue scale (0, no sweating, to 100, most severe sweating). Three weeks after treatment the difference between the botulinum-treated and placebo-treated axillae was -56.5% (P < 0.001), after 8 weeks -67.4% (P < 0.001) and after 13 weeks -62.5% (P < 0.001). No serious side-effects were observed.
In this paper we describe a new approach for the detection of clones in source code, which is inspired by the concept of frequent itemsets from data mining.The source code is represented as an abstract syntax tree in XML. Currently, such XML representations exist for instance for Java, C++, or PROLOG. Our approach is very flexible; it can be configured easily to work with multiple programming languages.
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.
