Clinician agreement on physical findings in child sexual abuse cases.

OBJECTIVE: To measure agreement among experienced clinicians regarding the interpretation of physical findings in child sexual abuse cases and to determine whether knowledge of clinical history affects the interpretation of the physical findings. DESIGN: Experienced clinicians rated colposcopic photographs on a scale of 1 to 5 with 1 being normal and 5 being clear evidence of penetrating injury. To answer an additional study question of whether clinical history affected interpretation, 4 clinicians rated 69 cases in which they were blinded to the patients' histories and 70 cases in which the patients' histories were available. The other 3 clinicians then rated the same cases with the presence or absence of history reversed. SETTING: All clinicians involved perform child sexual abuse examinations at tertiary care centers. PATIENTS: A total of 139 girls with Tanner stage 1 or 2 genitalia who were referred to a general pediatric clinic at an academic medical center for examination of possible sexual abuse. RESULTS: Half of the photographs were interpreted as indicating little or no evidence of abuse. Of those photographic sets that both readers could interpret, 39% were in perfect agreement and 77% disagreed by 1 category or less. Perfect agreement across all possible pairs of readers was 34.5%. Agreement was better when the patient's clinical history was unknown (29.3% vs 38.9%, P = .005). The kappa, a measure of interrater reliability, indicated poor agreement among clinicians. The combined kappa for the first group of clinicians was 0.22 without knowledge of clinical history and 0.11 with knowledge of clinical history. For the second group of clinicians, the kappa was 0.31 without knowledge of clinical history and 0.15 with knowledge of clinical history. The overall kappa across all 7 clinicians disregarding clinical history was 0.20. Agreement was best for categories 1 (normal, kappa = 0.28) and 5 (clear evidence of a penetrating injury, kappa = 0.39). CONCLUSIONS: Clinicians educated and experienced in assessing child sexual abuse do not agree perfectly on the interpretation of photographs of genital findings in girls with Tanner stage 1 or 2 genitalia. Clinicians agree less when a patient's clinical history is available. Efforts should be directed at standardizing physical findings and avoiding overemphasis on physical findings in child sexual abuse cases.

Cervical-vaginal and intraanal human papillomavirus infection of young girls with external genital warts.

To expand information regarding the epidemiology of genital human papillomavirus (HPV) infection in young girls, girls with external genital warts were examined for the prevalence of cervical-vaginal or intraanal HPV infection. Cervical-vaginal wash specimens and biopsies of external lesions were examined for HPV genotypes 1, 2, 4, 6, 11, and 16 using Southern transfer hybridization with restriction endonuclease fragment length analysis. Exfoliated cells from cervical-vaginal and intraanal canals were processed for cytologic study. Of 18 girls, 8 (44%) had cytologic or genomic evidence (or both) of cervical-vaginal or intraanal HPV infection. Five had cervical-vaginal wash specimens that were positive for HPV genome and showed mild dysplasia. As is true for adults, young girls with external anal-genital warts are also frequently infected with HPV at internal mucosal sites. Determining the immediate and long-term prognosis of infected children and those with intraepithelial neoplasia will require appropriate prospective studies.

Sexual abuse of human immunodeficiency virus-positive children. Outcomes for perpetrators and evaluation of other household children.

OBJECTIVE: To obtain the following data that pertain to programs for the prevention of sexual abuse and sexual transmission of human immunodeficiency virus (HIV) to children: (1) to determine the prevalence of sexual abuse among siblings and other children cohabiting with sexually abused HIV-positive children, and (2) to determine if programs designed to restrain identified perpetrators from further acts of child sexual abuse were instituted. DESIGN: Case series. SETTING: Households of previously described sexually abused HIV-infected children. PATIENTS AND OTHER PARTICIPANTS: Twenty-two siblings or other children who lived in the homes of 14 previously described HIV-infected sexually abused children. Eight perpetrators of the abuse were identified. MAIN OUTCOME MEASURES: Sexual abuse of cohabiting children was confirmed with disclosure interviews, witness by other persons, diagnosis of another sexually transmitted disease, or an abnormal physical examination result that was highly suggestive of sexual abuse. Telephone contact with the Department of Social Services, county sheriff or police, and district attorney provided data regarding reports, criminal indictments, trials, convictions, and plea-bargain arrangements for the identified perpetrators. RESULTS: Eleven (50%) of the 22 cohabiting children were confirmed to have been sexually abused and four (18%) were suspected of having been sexually abused. Seven (32%) of the cohabiting children could not be examined and it was not known if they had been sexually abused. No assailant was tried for a criminal offense, required to participate in offender therapy, or prohibited from unsupervised visitation of children. CONCLUSION: Programs for the prevention of sexual abuse and sexual transmission of HIV to children require means of ensuring the safety of children exposed to perpetrators and require adequate supervision of perpetrators and their adherence to therapy.

Evaluation of sexually abused and nonabused young girls for intravaginal human papillomavirus infection.

OBJECTIVE: The objective of this study was to compare the prevalence of intravaginal human papillomavirus-associated disease in two groups of girls to develop information regarding the means of transmission of anal-genital human papillomavirus disease. DESIGN: A pair of parallel studies of prevalence of human papillomavirus infections in two populations of prospectively enrolled girls. PATIENTS: Index patients consisted of 15 consecutive girls aged 11 years or younger who were confirmed to have been sexually abused, had signs or symptoms of vaginal disease, and required generalized anesthesia for evaluation. Selection of nonabused control patients was based on negative findings from screening evaluations and physical examinations. MAIN OUTCOME MEASURES: Prevalences of cervical-vaginal human papillomavirus infections in the two populations were compared. Vaginal wash samples from index and control patients were assayed for human papillomavirus 1, 2, 4, 6, 11, and 16 by reverse-blot and Southern transfer hybridization methods. Papanicolaou smears were examined from index patients. RESULTS: Vaginal wash samples from five (33%) of 15 index patients were positive for human papillomavirus 6, 11, or 16, compared with none of 17 controls. The presence or absence of external anal-genital warts was not correlated with results from the assay of intravaginal samples. Blinded readings of vaginal exfoliative cytologic findings of the index patients showed koilocytosis, atypia, or inflammatory reactions in four of five human papillomavirus-positive girls, and normal cytologic findings in one human papillomavirus-positive girl. CONCLUSION: These findings support other studies that indicate that sexual contact is a major route in the transmission of anal-genital human papillomavirus-related disease in children. Evaluation of intravaginal specimens was required to identify human papillomavirus-infected girls since the results of the wash samples were not correlated with the presence or absence of external anal-genital warts.

Human immunodeficiency virus transmission by child sexual abuse.

During 1987-1989, 14 (14.6%) of the 96 children who tested positive for the human immunodeficiency virus (HIV) and were followed up by the Duke University (Durham, NC) pediatric acquired immunodeficiency syndrome team were confirmed to have been sexually abused. Every sexually abused child was evaluated for each of five modes of HIV transmission, and in nine children the pathway was identified. Four of the study children acquired HIV from child sexual abuse and in six, abuse was a possible source. Transmission by child sexual abuse was the most frequent of the proven modes of acquisition of HIV in this population. The other proven modes of acquisition were vertical transmission (n = 3) and HIV-contaminated blood transfusion (n = 2). Twelve males were identified (n = 8) or suspected (n = 4) of being perpetrators. Three knew themselves to have HIV at the time of an assault and eight were aware that the child had HIV at the time of an assault. There was no indication from any child that "safe sex" precautions had been observed. Children with HIV infection had multiple risk factors for abuse or neglect. The sociological descriptors of the lives of the 14 abused children showed multiple known risk factors for sexual abuse that also overlapped with known risk factors for or sequelae of the acquisition of HIV infection. These included drug abuse and alcoholism in the home, prostitution of a parent, lack of parenting, poverty, and chronic illness of the child. Prevention efforts should recognize that children as well as adults are at risk for sexually transmitted HIV infection.
