Nomusa 12 year-old female ? Emerging teenager

Withdrawn & uncommunicative Gaining weight

Attended hospital Pregnant Abused over 5 week period Normal genital examination

Lessons - 1

Disclosure is relative & suspicion essential

Normal examination does NOT mean no sex

Pregnancy can occur before menarche

Sarah 3 year old female Abnormal social environment Abnormal behaviour Suspicious examination Angry parents

Allegations of abuse Consent for examination Admission to hospital

EXAMINING CHILDREN

The doctors despair.

PREPARATION

• Set the child at ease• Confirm the nature of his/her problem• Explain your role• Explain the procedure

• Chaperone• Examination

• Drapes - children• adolescents

• Specimen collection

PROCEDURE

• General examination• Tanner staging• Genital examination

NORMAL GENITAL ANATOMY &

DEVELOPMENT

Chaos & confusion!

FEMALE GENITAL DEVELOPMENT

• 3 phases:• Infancy• Childhood• Adolescence

• 3 features:• Oestrogen levels• Size• Mucosal surface

FEATURES OF SEXUAL ABUSE

The prosecutors despair.

Determining factors• Age:

• Oestrogen profile.• Vaginal environment.

• Nature of Abuse:• Rape • Seduction.

• Acute vs chronic.

• Time lapse:• Short.• Long.

Features.• Evidence of genital trauma.

• External genitalia.• Internal genitalia.

• Structural hymenal changes:• Trauma:

• Tears & Clefts / Notches.• “Dilatation”.

• T/V diameter & posterior rim.

• Foreign matter:• Semen.

• Sequelae:• STIs.• Pregnancy.

Sequelae

• Phsyical:• Acute trauma.• Evidence of penetration ~ 30%.• STI similar prevalence to broader

community• Syphilis – 1,8%.

• Pregnancy 1 – 1,5% of post pubertal girls.

INTERPRETATION OF CLINICAL FEATURES

What does it all mean?

CLASSIFICATION OF ANOGENITAL FINDINGS

• Class 1 - Normal• Class 2 - Nonspecific• Class 3 - Suspicious• Class 4 – Suggestive• Class 5 – Clear evidence of penetrating injury

Pediatrics 1994; 94: 311

NORMAL

• Periurethral bands• Intravaginal ridges or columns• Erythema in sulcus• Hymenal tags, mounds or bumps• Elongated hymenal orifice in obese child• Ample posterior hymenal rim (1 – 2 mm)• Oestrogenic changes• Diastasis ani / smooth area in perianal midline• Anal tag / thickened fold in perianal midline

NONSPECIFIC

• Erythema of vestibule• Increased vascularity of vestibule / hymen• Labial adhesions• Rolled hymenal edges• Narrow hymenal edge, at least 1 mm• Vaginal discharge• Anal fissure• Flattened / thickened anal folds• Anal dilatation with visible stool• Venous congestion of perianal tissue (delayed)

SUSPICIOUS

• Enlarged hymenal orifice• Posterior hymenal rim < 1 mm• Acute abrasion or laceration of labia or vestibule• Condylomata accuminata• Immediate anal dilatation with no visible stool• Immediate perianal venous congestion• Distorted, irregular anal folds

SUGGESTIVE

• 2 or more suspicious anal or genital findings• Scar or laceration of posterior fourchette with

sparing of hymen• Scar in perianal area

CLEAR EVIDENCE OF PENETRATING INJURY

• Hymenal notch between 3 and 9 o’clock• Hymenal transection or laceration• Laceration of posterior fourchette extending to

involve hymen• Scar of posterior fourchette with loss of hymenal

tissue between 5 and 7 o’clock• Perianal laceration extending deep to external

anal sphincter

LIKELIHOOD OF SEXUAL ABUSE

• Class 1 – No evidence of abuse• Class 2 – Possible abuse• Class 3 – Probable abuse• Class 4 – Definite evidence of abuse

Pediatrics 1994; 94: 311

NO EVIDENCE OF ABUSE

• Normal examination, no history, no behavioural changes, no witness

• Nonspecific findings with another aetiology and no history or behavioural change

• Child considered at risk for sexual abuse, but gives no history and has nonspecific behavioural changes

POSSIBLE ABUSE

• Class 1, 2 or 3 findings in combination with significant behavioural changes but child unable to give history of abuse

• Condylomata or genital herpes in absence of a history of abuse and otherwise normal examination

• Child has made a statement but this not consistent or detailed

PROBABLE ABUSE

• Child gives clear, consistent and detailed story• Class 4 or 5 findings with no convincing history

of accidental penetrating injury• Culture proven infection with Chlamydia

trachomatis in a prepubertal child over 2 years of age

DEFINITE EVIDENCE OF SEXUAL ABUSE

• Finding sperm of seminal fluid in or on a child’s body

• Witnessed episode of sexual molestation• Nonaccidental, blunt penetrating injury to the

vaginal or anal orifice• Confirmed infection with Neisseria gonorrhoea or
