This study is the first in the field of pharmacogenetics in Greek psoriasis patients. Further, larger studies are required to validate our findings and replicate them in various populations.
BackgroundIncobotulinumtoxinA (Xeomin Cosmetic®) has been used previously in the management of masseteric hypertrophy. However, a standardized injection technique has not been established. The goal of the present study was to evaluate the efficacy and safety of two injection techniques in the management of masseteric hypertrophy using incobotulinumtoxinA.MethodsThirty female patients with masseteric hypertrophy were recruited and evenly randomized to receive bilateral treatments of either a single-injection technique (SIT) or a multiinjection technique (MIT). Improvement of masseteric hypertrophy was assessed at week 16 using standardized measurements and photographs. Patients completed a 5-point satisfaction questionnaire while physicians completed the Global Aesthetic Improvement Scale (GAIS) and 10-point photonumeric masseter prominence rating scale.ResultsThere were no significant differences in physician ratings on the photonumeric scale and GAIS between the SIT and MIT groups. Results of the standardized measurements also revealed no significant difference between injection techniques. Majority of patients at every visit reported being “satisfied” with treatment results. Clinically, the number and severity of adverse events were similar between groups.ConclusionThis study supports the noninferiority of both SIT and MIT with regard to efficacy and safety in the management of masseteric hypertrophy, using incobotulinumtoxinA.
Gender distribution, type of psoriasis, and body area affection is almost the same as in adults. Most of the patients presented with mild disease of little extent, possibly indicating the favorable effect of sun in a Mediterranean country. The most often prescribed treatment for the majority of patients was topical.
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.
