The SWIFT Model for Lichen Sclerosus Among Premenarchal Girls

Area of Science:

• Pediatric Dermatology
• Gynecology
• Clinical Diagnostics

Background:

• Childhood lichen sclerosus (LS) diagnosis is often delayed.
• Efficient evaluation tools are needed for timely risk stratification.
• Pediatric vulvovaginal complaints require accurate diagnostic methods.

Purpose of the Study:

• To develop a prognostic tool for rapid risk stratification of LS in premenarchal girls.
• To create an efficient evaluation tool to ameliorate diagnostic delays in childhood LS.
• To establish an accurate model for identifying LS in young females.

Main Methods:

• Retrospective chart review of premenarchal girls with vulvovaginal complaints.
• Development of a predictive model for LS using 18 signs and symptoms in a pilot study (69 patients).
• Validation and refinement of the model using cluster-based analytics on a larger dataset (105 additional patients).

Main Results:

• The SWIFT (Soreness, Whitening, Urinary incontinence, Fissures, Thickening of the clitoral hood) model was developed.
• The refined model demonstrated >97% accuracy in predicting LS among 174 patients.
• Key predictors identified include soreness, whitening, urinary incontinence, fissures, and clitoral hood thickening.

Conclusions:

• The SWIFT model provides accurate prediction of clinical LS diagnosis in premenarchal girls.
• This tool can significantly aid in the timely diagnosis and treatment of LS in pediatric patients.
• Further replication in diverse patient populations is recommended to confirm generalizability.
