Trichotillomania in Children.

Area of Science:

• Pediatric dermatology
• Child psychology
• Behavioral science

Background:

• Trichotillomania (hair-pulling disorder) is frequently underdiagnosed in children.
• Limited data exists on the specific characteristics of pediatric trichotillomania.
• Understanding childhood trichotillomania is crucial for early identification and intervention.

Purpose of the Study:

• To characterize pediatric trichotillomania by analyzing patient demographics, clinical presentation, and potential triggers.
• To enhance clinical awareness and diagnostic capabilities for this condition in children.
• To provide a foundation for future research into childhood trichotillomania.

Main Methods:

• Retrospective analysis of an electronic database from a tertiary children's hospital.
• Systematic classification of patient data using the '5 Ws and 1 H' framework (Who, What, When, Where, Why, How).
• Inclusion of data on patient demographics, clinical signs, observed triggers, and diagnostic tests.

Main Results:

• 33 patients diagnosed with trichotillomania (28 female, 5 male), with a peak age of 3-4 years.
• Scalp hair pulling was most common; nail biting co-occurred in 5 patients.
• Parents noticed hair pulling in only 51.5% of cases; hair found on bedding was a common clue. Triggers included appearance, family, school, and illness. The hair pull test was negative in all patients.

Conclusions:

• A structured questioning approach based on '5 Ws and 1 H' aids in diagnosing unexplained nonscarring hair loss in children.
• This method assists clinicians, especially those unfamiliar with trichotillomania, in gathering essential information.
• Increased clinician awareness of trichotillomania characteristics can improve diagnosis and management of this condition.
