Background and Objective:There is no validated instrument to assess the clinical severity of striae distensae. Here, we aimed to develop a striae distensae severity scale.
Material and Methods:After a Delphi-based consensus, 15 items related to striae severity were assessed in 110 areas (breasts, abdomen, and buttocks) from 45 participants. The items were analyzed through a partial least squares model to select the most important variables. To assess the reliability of the scale, 43 areas were retested.Results: Of the 110 areas evaluated, 34 were breasts, 24 abdomens, and 52 buttocks.Striae were considered mild in 30% of the evaluations, moderate in 33%, severe in 21%, and extremely severe in 16%. The final model was composed by: width of the widest striae, width of the striae with the most frequent pattern, atrophy, number of affected quadrants, distribution (multiple or isolated), hypo or hyperchromia and topography. The scores of the scale demonstrated a high correlation with the clinical classification (rho = 0.77). There was a high agreement in the scores from the reassessed areas (intraclass correlation coefficient = 0.90).
Conclusion:An objective and reliable scale to assess the clinical severity of striae distensae on the breasts, abdomen, and buttocks was developed.
Pyoderma gangrenosum is a rare neutrophilic dermatosis of unknown etiology, of
which the most frequent clinical manifestations are ulcers. The diagnosis
difficulty is, among other things, to rule out other causes of ulcers, since it
is considered a diagnosis of exclusion. Skin ulcerations may also occur in the
iliac vein compression syndrome, which, like pyoderma gangrenosum, mainly
affects young women. Because they have such similar characteristics, the
presence of vascular disease may hinder the diagnosis of concurrent pyoderma
gangrenosum. Because of the clinical relevance of ulcerated lesions and scars,
the early diagnosis and treatment of this condition is considered extremely
important. We report a case in which the two diseases were associated, hampering
the diagnosis of pyoderma gangrenosum.
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.
