Follow up study eight years after diagnosis of sexual abuse.

AIM: To study the outcome over an eight year period of children determined by paediatricians in 1989 as definitely or probably sexually abused. METHOD: Information was obtained on 140 of 148 children diagnosed in 1989 when aged 7 or less. Sources were hospital medical records and school health records. School health records of a comparison group of 83 children were also examined. RESULTS: A variety of problematic characteristics were found significantly more often in the abused group than the comparison group. These included surname changes (30% v 2%), removal from home (25% v 1%), number of home addresses (2.8 v 1.4), and schools attended (3.4 v 2.2). Other significant findings included further abuse (35% v 0%), adverse behaviours (60% v 16%), educational problems (24% v 5%), chronic health problems (54% v 36%), and involvement of mental health services (32% v 1%).

Abuse of children in foster and residential care.

OBJECTIVE: There have recently been many debates in the UK about how to provide good care for children placed away from home. Professionals have realized that the level of child abuse in foster care and children's homes is high. This research examines the characteristics of physical and sexual abuse of children in foster and residential care in a city in England. The number of cases of abuse reported by pediatricians in this group was compared to the number reported by the same pediatricians for the population of Leeds as a whole. METHOD: This is a retrospective study of 158 children, fostered or in residential care who were involved in 191 episodes of alleged physical and/or sexual abuse assessed and reported by pediatricians over a 6 year period from 1990 to 1995 in Leeds, England. Details of the child including the reason for placement in care, their physical and mental health, abuse characteristics, including perpetrator and case management were studied. RESULTS (see Table 1): 158 incidents of abuse in 133 children in foster/residential care are described. In foster care, 42 children were physically abused, 76 were sexually abused, and 15 experienced both forms of abuse. In residential care, 12 children were physically abused, 6 were sexually abused, and 6 experienced both forms of abuse. In foster care 60% of sexual abuse involved girls and 60% of physical abuse involved boys. In residential care almost twice as many boys as girls were reported to be abused. Foster carers perpetrated the abuse for 41%, natural parents on contact for 23%, and children 20% of incidents. A significant proportion of abuse was severe with 1 death, 8 children with burns, 18 with genital, and 34 with anal penetration. Long-standing emotional, behavioral and learning difficulties were common. Most children (80%) had been abused prior to entry into care. Foster children were 7-8 times and children in residential care 6 times more likely to be assessed by a pediatrician for abuse than a child in the general population. CONCLUSIONS: Children in foster or residential care form an at risk group for maltreatment. Their special needs include additional measures to protect them from abuse.

Disturbed anal sphincter function following vaginal delivery.

BACKGROUND: Recently interest in idiopathic (neurogenic) faecal incontinence has swung from denervation of the external anal sphincter to the internal sphincter. AIMS: To evaluate the effects of vaginal delivery on the internal sphincter. SUBJECTS: 1372 mothers were studied antenatally and 1202 were accepted into the study. METHODS: Sphincter pressures were measured antenatally, in the early postnatal period, and six to 10 weeks later in selected patients. RESULTS: 755 of 1202 subjects assessed antenatally were primiparous women and 447 multiparous women. Some 320 previous spontaneous vaginal deliveries (SVD) (mean 59 mm Hg) and 67 previous forceps deliveries (mean 58 mm Hg) had lower resting pressures than 755 primiparous women (mean 66 mm Hg) (p < 0.01). A total of 493 subjects were reassessed postnatally. There were 372 SVDs, 47 vacuum extractions, 20 forceps, and 54 caesarean deliveries. All vaginal deliveries but not caesarean sections dropped their resting anal pressures from antenatal values (p < 0.001). Some 227 first SVDs had a much greater fall than 145 subsequent SVDs. In 162 subjects who had undergone their first vaginal delivery and who were followed up there was some recovery but the resting pressures were still lowered at six to 10 weeks post partum. CONCLUSIONS: The first vaginal delivery causes a permanent lowering of resting anal pressures. The possible reasons for this are discussed.

Colposcopic genital findings in prepubertal girls assessed for sexual abuse.

After the introduction of the colposcope for the examination of children suspected of being sexually abused in Leeds, a study was undertaken to describe the findings in detail. A total of 109 consecutive prepubertal girls, mean age 70.4 months were assessed including colposcopic genital and anal examination, and peer group review of reports and photographs. Fifty nine children had signs consistent with blunt force penetrating trauma (hymenal transection/major notch, scar, or hymenal attenuation). Transections were encountered most commonly at 6 o'clock (directly posterior). In 46 the hymenal orifice was gaping with thigh abduction only and in 47 the hymenal orifice transverse diameter was greater than 4 mm on labial separation. Overall, physical findings were commonly present and in only two cases were no signs recorded. Non-specific and frequent findings included patterns of labial and introital reddening. Supportive hymenal signs including swelling, rounding of edge, thickening, distortion, and loss of symmetry were common. Labial fusion was present in 20. Urethral dilatation with labial separation was noted in 14. Physical findings including normality are consistent with abuse and even minor anogenital signs as well as negative findings should be documented. Colposcopy and photography are valuable tools in peer review, teaching, and case management.

Severe amoebic colitis requiring colonic resection.

A 54 year old Australian man presented with fulminant amoebic colitis. Although the amoebae were eradicated, his colonic function did not recover. Colectomy was required. Situations where the surgeon may encounter amoebiasis are discussed.

Evaluating the pelvic floor in obstetric patients.

Up to 40% of vaginal deliveries lead to pelvic floor denervation. This has been linked causally with the later occurrence of urinary incontinence, faecal incontinence and vaginal prolapse. Pelvic floor position, anal sphincter pressures and anal electrosensitivity were evaluated in 72 volunteers as simple screening tests for detecting patients who might benefit from neurological assessment. A lower perineum and reduced voluntary sphincter pressures were found antenatally in parous women when compared with nulliparas. The tests were repeated postnatally 24 to 72 hours after delivery. When compared with antenatal readings, the perineum was lower and sphincter pressures were reduced in subjects delivered vaginally. Forty one subjects were reexamined after 6-8 weeks and partial recovery was found. Anal squeeze pressures and pelvic floor position when straining were the results most consistently changed. On the basis of this study it is suggested that 28% of multiparas seen anrenatally and between 25% to 30% of all women who deliver vaginally may be eligible for more detailed neurological study.

The sexually abused battered child.

A total of 130 children were identified in whom both evidence of sexual abuse and non-accidental, non-genital physical injuries (bruises, fractures, scratches, burns and scalds, including failure to thrive) were found. There were 77 girls and 53 boys with mean ages 5.7 and 6.8 years respectively and the peak age between the second and seventh birthdays; this reflects previous reports indicating that physical and sexual abuse predominantly involves young children. Patterns of injury that suggested sexually motivated assault included bruises, scratches, and burns around the lower trunk and genitalia, thighs, buttocks, and upper legs including knees. Pinch and grip marks were found where the child was held. The sexual abuse often involved attempted or achieved penetration of mouth, vagina, or anus, and physical signs were seen relatively more often than in sexually abused children as a whole. Four children died and sexual aggression and child death in the domestic setting may be linked. One in six of 769 physically abused children (16.9%) and one in seven of 949 sexually abused children (13.6%) have suffered both forms of abuse.
