Child sexual abuse. Physical examination.

Area of Science:

• Pediatric Forensics
• Child Abuse Research
• Forensic Gynecology

Background:

• Child sexual abuse is a significant public health concern.
• Accurate physical examination is crucial for evidence collection in suspected cases.
• Standardized methods for assessing genital trauma in children are needed.

Purpose of the Study:

• To evaluate a new, simple, and reproducible method for measuring hymenal opening in children.
• To assess physical evidence of trauma in children suspected of sexual abuse.
• To correlate physical findings with historical information to determine the occurrence of sexual abuse.

Main Methods:

• A population-based study involving 41 children (aged 0-17 years) was conducted.
• Twenty-nine children underwent physical examination, including measurement of the hymenal opening using transparent test tubes of known diameters.
• Examinations were performed without anesthesia.

Main Results:

• Physical evidence of trauma or disease, including a dilated hymenal opening, was observed in 19 out of 29 examined children.
• Based on examination findings and anamnestic information, sexual abuse was indicated in 10 cases.
• Convictions were secured in only 3 of the cases where sexual abuse was indicated.

Conclusions:

• The new method for hymenal opening measurement is simple and reproducible.
• Physical evidence of trauma is common in children suspected of sexual abuse.
• Further research is necessary to establish age-related normal variations in genital anatomy to aid in interpretation.
