Impact of Screening and Co-located Parent Coaching Within Pediatric Primary Care on Child Health Care Use: A Stepped Wedge Design.

Childhood adversity and toxic stress have been associated with poor mental and physical health. This study examined if Parent Connext, a program that integrates adversity screening and parent coaching by co-located specialists within pediatric primary care, had an impact on health care utilization. This stepped wedge cluster randomized controlled trial evaluated Parent Connext across six pediatric primary care practices. All practices (clusters) were in the control period during year 1. Three practices were randomized to begin the Parent Connext intervention in year 2, and three practices were randomized to begin in year 3. Medical records of all patients under age 8 treated at these practices during these 3 years were queried retrospectively for participant-level primary outcomes (sick visits, emergency department visits, hospitalizations) and secondary outcomes (well-child and immunization adherence, referrals). The study sample included 27,419 patients followed for an average 1.39 (SD = 0.66) years in the control period and 1.07 (SD = 0.60) years in the intervention period. During the intervention period, patients had significantly fewer sick visits (IRR = 0.91, p < 0.001) which aligned with our hypothesis, decreased odds of well-child visit adherence (OR = 0.88, p < 0.001) which was unexpected, and increased odds of receiving a referral (OR = 1.45, p < 0.001). The odds of an emergency department visit, hospitalization, and 2-year immunization adherence did not differ between periods. Parent Connext resulted in a significant reduction in child sick visits, highlighting the potential benefit of two-generation approaches to pediatric care for child health.

Identification of Initial and Subsequent Injury in Young Infants: Opportunities for Quality Improvement in the Evaluation of Child Abuse.

METHODS: Six children's hospitals identified infants with an initial injury and recurrent injury over a 1-year period using 2 methods: (1) diagnostic code method - infants 6 months or younger presenting with at least 1 diagnostic code for injury were tracked for 12 months to determine the frequency of recurrent injury, and (2) consult method - all available medical records of children 18 months or younger seen for an inpatient consultation for suspected child abuse were reviewed to identify history of a first injury at 6 months or younger. RESULTS: Using the diagnostic code method, 682 unique infants were identified with initial injuries, most commonly fractures (37.0%), bruising/ecchymosis (35.9%), and superficial injuries (28.3%). Forty-two infants (6.2%) returned with a second injury, and no demographic factors were significantly associated with the likelihood of a second injury. Using the consult method, 37 of 342 consults (10.8%) were identified as having a history of at least 1 initial injury. Of the initial injuries identified, the most common was bruising/ecchymosis (64.9%). The number of injuries identified with either method varied significantly across hospitals, as did completion of skeletal surveys for infants with bruising (range, 4.5%-71.1%; P < 0.001) and any injury (range, 4.4%-62.7%; P < 0.001). CONCLUSIONS: Our study demonstrates that young infants who experience 1 injury often experience a second injury. There exists significant variability in the identification of injury and the completion of skeletal surveys across a network of 6 children's hospitals. A standardized quality improvement approach may improve identification of injury and reduce the variability in practice observed.

Providers' Ability to Identify Sentinel Injuries Concerning for Physical Abuse in Infants.

OBJECTIVES: The objectives of this study were to assess the ability of pediatric health care providers and social workers to recognize sentinel injuries in infants under 6 months of age and to determine what factors influence their decision to evaluate for physical abuse. METHODS: A statewide collaborative focused on sentinel injuries administered a survey to pediatric health care providers and social workers in the emergency department, urgent care, and primary care. The survey contained 8 case scenarios of infants under 6 months of age with an injury, and respondents were asked if they would consider the injury to be a sentinel injury requiring a physical abuse evaluation. Respondents were then presented with several factors and asked how much each influences the decision to perform a physical abuse evaluation. RESULTS: A total of 565 providers completed the survey. Providers had moderate interrater reliability on their classification of the cases as sentinel injuries or not (κ = 0.57). Nearly all respondents (97%) recognized genital bruising as a sentinel injury, whereas 77% of respondents recognized intraoral injuries. Agreement was highest among social workers (κ = 0.76) and physicians with categorical pediatrics training and pediatric emergency medicine fellowship (κ = 0.63) and lowest among nurse practitioners (κ = 0.48) and residents (κ = 0.51). Concern over missing the diagnosis of abuse had the greatest influence on the decision to perform a physical abuse evaluation. CONCLUSIONS: Sentinel injuries are not uniformly recognized as potential signs of child abuse requiring further evaluation by pediatric health care providers. Additional evidence and education are needed regarding sentinel injuries.

Co-located Parent Coaching Services Within Pediatric Primary Care: Feasibility and Acceptability.

INTRODUCTION: This project assessed the feasibility and acceptability of Parent Connext, a positive parenting program that integrates screening and co-located parent coaching within pediatric primary care. METHOD: Eleven practices implemented Parent Connext in phases between November 1, 2016, and July 31, 2019. Screening and surveillance for parenting and family psychosocial concerns were performed during patient visits. Providers responded with brief motivational interviewing and referral. Parenting Specialists provided individualized parent coaching to referred caregivers. RESULTS: Screens were completed at 13,346 (65%) targeted visits, with 26% positive for concerns. Parent coaching was provided to 1,301 of 2,711 (48%) referred families (average 2.2 sessions per family). Providers and staff felt significantly more supported, confident, and knowledgeable about addressing parenting and family psychosocial concerns after implementing Parent Connext and felt the program improved their relationships with families and quality of care. DISCUSSION: Co-located parent coaching was found to be a feasible and worthwhile addition to pediatric primary care.

Chlamydia Conjunctivitis in 2 Prepubertal Children: An Uncommon Presentation of Child Sexual Abuse.

Sexually transmitted infection as the result of child sexual abuse in prepubertal children is uncommon. Chlamydia trachomatis conjunctivitis is an even less common entity in prepubertal children outside the newborn period. This report details the presentation of 2 children with conjunctivitis who were subsequently diagnosed as having C. trachomatis conjunctivitis. One child was also diagnosed as having rectal and pharyngeal C. trachomatis infection, and the other also had genital C. trachomatis infection. Even with multisite C. trachomatis infection as an indication of sexual abuse, neither child gave a detailed disclosure of abuse to account for their infections. The absence of a clear disclosure is not uncommon. Previous literature reports that a disclosure in these circumstances occurs in less than half of cases. In this report, we review the recommendations for diagnosis of C. trachomatis using nucleic acid amplification testing and culture as well as treatment. Specific clinical features should alert the clinician to C. trachomatis conjunctivitis and lead to timely diagnosis and protection of the child from further sexual abuse.

Parental Adverse Childhood Experiences and Pediatric Healthcare Use by 2 Years of Age.

OBJECTIVE: To determine whether maternal and paternal exposure to adverse childhood experiences (ACEs) has an association with offspring healthcare use by 2 years of age. STUDY DESIGN: A retrospective cohort study was performed on 454 patients at a large suburban pediatric primary care practice whose mother (n = 374) or father (n = 156) or both (n = 123) completed an ACE survey between October 2012 and June 2014. The association between self-reported parental ACEs and healthcare use by 2 years of age, including number of missed well-child visits, sick visits, and delayed or missed immunizations, was modeled using multivariable negative binomial regression. All analyses adjusted for child sex, payer source, and preterm birth. RESULTS: Maternal, but not paternal, ACE exposure was significantly associated with missed well-child visits by 2 years of age. For each additional maternal ACE, there was a significant 12% increase in the incidence rate of missed well-child visits (relative risk, 1.12; 95% CI, 1.03-1.22; P = .010). Maternal and paternal ACE scores were not significantly associated with increased sick visits or delayed or missed immunizations. CONCLUSIONS: The ACE exposure of mothers is negatively associated with adherence to preventive healthcare visits among their children early in life. Future research is needed to elucidate the mechanisms of this association and to develop and implement family-based intervention strategies.

Caution Is Required When Using Non-Food and Drug Administration-Cleared Assays to Diagnose Sexually Transmitted Infections in Children.

Nucleic acid amplification testing is the gold-standard for Chlamydia trachomatis and Neisseria gonorrhoeae testing in adults. We present 3 pediatric cases in which testing resulted in probable false-positive results. Clinicians should avoid tests without clearance from a regulatory agency and should maintain consistent communication with laboratories.

Integration of the Safe Environment for Every Kid (SEEK) Model Across Primary Care Settings.

This project sought to assess the generalizability, barriers, and facilitators of implementing the Safe Environment for Every Kid (SEEK) model for addressing psychosocial risk factors for maltreatment across multiple primary care settings, including a pediatric practice, federally qualified health center, and family medicine practice. The SEEK model includes screening caregivers for psychosocial risk factors at well-child visits age 0 to 5 years, brief intervention incorporating principles of motivational interviewing to engage caregivers, and referral to treatment. All practices successfully implemented SEEK, with screening completion rates from 75% to 93% and brief intervention rates from 61% to 81%. Major parental stress (14%) and food insecurity (11%) were the most common risk factors. Providers found SEEK worthwhile for improving their knowledge, skills, and ability to address psychosocial concerns and provide whole person care. Barriers included limited time and resources, incomplete resource knowledge, and lack of follow-up. Facilitators included on-site support staff to assist with communication and referrals.

Parental Adverse Childhood Experiences and Offspring Development at 2 Years of Age.

OBJECTIVES: The study objective was to determine if maternal and paternal exposure to adverse childhood experiences (ACEs) have a significant association with negative offspring development at 24 months of age in a suburban pediatric primary care population. METHODS: A retrospective cohort study was conducted of 311 mother-child and 122 father-child dyads who attended a large pediatric primary care practice. Children were born from October 2012 to June 2014, and data were collected at the 2-, 4-, and 24-month well-child visits. Multivariable Poisson regression with robust error variance was used to model the relationship between self-reported parental ACEs and the outcomes of suspected developmental delay at 24 months and eligibility for early intervention services. RESULTS: For each additional maternal ACE, there was an 18% increase in the risk for a suspected developmental delay (relative risk: 1.18, 95% confidence interval: 1.08-1.29). A similar trend was observed for paternal ACEs (relative risk: 1.34, 95% confidence interval: 1.07-1.67). Three or more maternal ACEs (versus <3 ACEs) was associated with a significantly increased risk for a suspected developmental delay that affected multiple domains. Similar effects were observed for early intervention services. CONCLUSIONS: Parental ACE exposures can negatively impact child development in multiple domains, including problem solving, communication, personal-social, and motor skills. Research is needed to elucidate the psychosocial and biological mechanisms of intergenerational risk. This research has implications for the value of parental ACE screening in the context of pediatric primary care.

Extraovarian gonadotropin negative feedback revealed by aromatase inhibition in female marmoset monkeys.

Whereas the ovary produces the majority of estradiol (E2) in mature female primates, extraovarian sources contribute to E2 synthesis and action, including the brain E2-regulating hypothalamic gonadotropin-releasing hormone. In ovary-intact female rodent models, aromatase inhibition (AI) induces a polycystic ovary syndrome-like hypergonadotropic hyperandrogenism due to absent E2-mediated negative feedback. To examine the role of extraovarian E2 on nonhuman primate gonadotropin regulation, the present study uses letrozole to elicit AI in adult female marmoset monkeys. Sixteen female marmosets (Callithrix jacchus; >2 yr) were randomly assigned to ovary-intact or ovariectomy (OVX) conditions and subsequently placed on a daily oral regimen of either ~200 µl vehicle alone (ovary-intact Control, n = 3; OVX, n = 3) or 1 mg ⋅ kg-1 ⋅ day-1 letrozole in vehicle (ovary-intact AI, n = 4; OVX + AI, n = 6). Blood samples were collected every 10 days, and plasma chorionic gonadotropin (CG) and steroid hormone levels were determined by validated radioimmunoassay and liquid chromatography/tandem mass spectrometry, respectively. Ovary-intact, AI-treated and OVX females exhibited elevated CG (P < 0.01, P = 0.004, respectively) compared with controls, and after 30 days, OVX + AI females exhibited a suprahypergonadotropic phenotype (P = 0.004) compared with ovary-intact + AI and OVX females. Androstenedione (P = 0.03) and testosterone (P = 0.05) were also elevated in ovary-intact, AI-treated females above all other groups. The current study thus confirms in a nonhuman primate that E2 depletion and diminished negative feedback in ovary-intact females engage hypergonadotropic hyperandrogenism. Additionally, we demonstrate that extraovarian estrogens, possibly neuroestrogens, contribute to female negative feedback regulation of gonadotropin release.

Maternal Interpersonal Trauma and Child Social-Emotional Development: An Intergenerational Effect.

BACKGROUND: Evidence suggests that maternal interpersonal trauma can adversely affect offspring health, but little is known about potential transmission pathways. We investigated whether interpersonal trauma exposure had direct and indirect associations with offspring social-emotional development at 12-months of age in an at-risk, home visited population. METHODS: A retrospective cohort study was conducted of 1172 mother-child dyads who participated in a multi-site, early childhood home visiting program. Children were born January 2007 to June 2010 and data were collected at enrolment (prenatal/birth) through 12-months of age. Multivariable path analyses were used to examine the relationship between maternal interpersonal trauma, subsequent psychosocial mediators (maternal depressive symptoms, social support, and home environment), and the outcome of child social-emotional development measured with the Ages and Stages Questionnaire: Social-Emotional (ASQ:SE). Maternal interpersonal trauma was characterized as any previous exposure, the level of exposure, and type (e.g. abuse) of exposure. RESULTS: The prevalence of maternal interpersonal trauma exposure was 69.1%, and exposures ranged from 1 type (19.3%) to 7 types (2.3%). Interpersonal trauma was associated with a 3.6 point (95% confidence interval 1.8, 5.4) higher ASQ:SE score among offspring and indicated greater developmental risk. An estimated 23.4% of the total effect was mediated by increased maternal depressive symptoms and lower social support. Differential effects were observed by the level and type of interpersonal trauma exposure. CONCLUSION: Maternal interpersonal trauma exposures can negatively impact child social-emotional development, acting in part through maternal psychosocial factors. Future research is needed to further elucidate the mechanisms of intergenerational risk.

ERα Signaling Is Required for TrkB-Mediated Hippocampal Neuroprotection in Female Neonatal Mice after Hypoxic Ischemic Encephalopathy(1,2,3).

Male neonate brains are more susceptible to the effects of perinatal asphyxia resulting in hypoxia and ischemia (HI)-related brain injury. The relative resistance of female neonatal brains to adverse consequences of HI suggests that there are sex-specific mechanisms that afford females greater neuroprotection and/or facilitates recovery post-HI. We hypothesized that HI preferentially induces estrogen receptor α (ERα) expression in female neonatal hippocampi and that ERα is coupled to Src family kinase (SFK) activation that in turn augments phosphorylation of the TrkB and thereby results in decreased apoptosis. After inducing the Vannucci's HI model on P9 (C57BL/6J) mice, female and male ERα wild-type (ERα(+/+)) or ERα null mutant (ERα(-/-)) mice received vehicle control or the selective TrkB agonist 7,8-dihydroxyflavone (7,8-DHF). Hippocampi were collected for analysis of mRNA of ERα and BDNF, protein levels of ERα, p-TrkB, p-src, and cleaved caspase 3 (c-caspase-3) post-HI. Our results demonstrate that: (1) HI differentially induces ERα expression in the hippocampus of the female versus male neonate, (2) src and TrkB phosphorylation post-HI is greater in females than in males after 7,8-DHF therapy, (3) src and TrkB phosphorylation post-HI depend on the presence of ERα, and (4) TrkB agonist therapy decreases the c-caspase-3 only in ERα(+/+) female mice hippocampus. Together, these observations provide evidence that female-specific induction of ERα expression confers neuroprotection with TrkB agonist therapy via SFK activation and account for improved functional outcomes in female neonates post-HI.

Updated Guidelines for the Medical Assessment and Care of Children Who May Have Been Sexually Abused.

The medical evaluation is an important part of the clinical and legal process when child sexual abuse is suspected. Practitioners who examine children need to be up to date on current recommendations regarding when, how, and by whom these evaluations should be conducted, as well as how the medical findings should be interpreted. A previously published article on guidelines for medical care for sexually abused children has been widely used by physicians, nurses, and nurse practitioners to inform practice guidelines in this field. Since 2007, when the article was published, new research has suggested changes in some of the guidelines and in the table that lists medical and laboratory findings in children evaluated for suspected sexual abuse and suggests how these findings should be interpreted with respect to sexual abuse. A group of specialists in child abuse pediatrics met in person and via online communication from 2011 through 2014 to review published research as well as recommendations from the Centers for Disease Control and Prevention and the American Academy of Pediatrics and to reach consensus on if and how the guidelines and approach to interpretation table should be updated. The revisions are based, when possible, on data from well-designed, unbiased studies published in high-ranking, peer-reviewed, scientific journals that were reviewed and vetted by the authors. When such studies were not available, recommendations were based on expert consensus.

High fat diet decreases beneficial effects of estrogen on serotonin-related gene expression in marmosets.

The administration of estradiol-17ß (E) to animal models after loss of ovarian steroid production has many beneficial effects on neural functions, particularly in the serotonin system in nonhuman primates (NHPs). E also has anorexic effects, although the mechanism of action is not well defined. In the US, obesity has reached epidemic proportions, and blame is partially directed at the Western style diet, which is high in fat and sugar. This study examined the interaction of E and diet in surgically menopausal nonhuman primates with a 2×2 block design. Marmosets (Callithrix jacchus; n=4/group) were placed on control-low fat diet (LFD; 14%kcal from fat) or high fat diet (HFD; 28%kcal from fat) 1month prior to ovariectomy (Ovx). Empty (placebo) or E-filled Silastic capsules were implanted immediately following Ovx surgery. Treatments extended 6months. The established groups were: placebo+LFD, E+LFD, placebo+HFD, or E+HFD. At necropsy, the brain was flushed with saline and harvested. The midbrain was dissected and a small block containing the dorsal raphe nucleus was processed for qRT-PCR using Evagreen (Biotinum). Genes previously found to impact serotonin neural functions were examined. Results were compared with 2-way ANOVA followed by Bonferroni post-hoc tests or Cohen's D analysis. There was a significant effect of treatment on tryptophan hydroxylase 2 (TPH2) across the groups (p=0.019). E stimulated TPH2 expression and HFD prevented E-stimulated TPH2 expression (p<0.01). Treatment differentially affected monoamine oxidase B (MAO-B) across the groups (p=0.05). E increased MAO-B with LFD, and this stimulatory effect was prevented by HFD (p<0.05). There was a significant difference between treatments in corticotrophin releasing factor-receptor 2 (CRF-R2) expression (p=0.012). E increased CRF-R2 and this stimulatory effect was blocked by HFD (p<0.01). Regardless of diet, E increased Fev mRNA (p=0.028) and decreased CRF-receptor 1 (CRF-R1) mRNA (p=0.04). HFD suppressed urocortin 1 (UCN1; stresscopin) expression (p=0.045) but E treatment had no effect. Monoamine oxidase A (MAO-A) was different due to treatment across the groups (p=0.028). MAO-A was increased in the E+HFD group (p<0.01) whereas previous studies showed E suppressed MAO-A in macaques. The serotonin reuptake transporter (SERT), the serotonin 1A receptor (5HT1A), estrogen receptor beta (ERß) and progestin receptor (PR) expressions were not different between groups. Estrogen receptor alpha (ERα) was undetectable. In summary, the data indicate that important actions of hormone therapy in the serotonin system may be lost in the context of a HFD.

Utility of hepatic transaminases in children with concern for abuse.

OBJECTIVE: Routine testing of hepatic transaminases, amylase, and lipase has been recommended for all children evaluated for physical abuse, but rates of screening are widely variable, even among abuse specialists, and data for amylase and lipase testing are lacking. A previous study of screening in centers that endorsed routine transaminase screening suggested that using a transaminase threshold of 80 IU/L could improve injury detection. Our objectives were to prospectively validate the test characteristics of the 80-IU/L threshold and to determine the utility of amylase and lipase to detect occult abdominal injury. METHODS: This was a retrospective secondary analysis of the Examining Siblings To Recognize Abuse research network, a multicenter study in children younger than 10 years old who underwent subspecialty evaluation for physical abuse. We determined rates of identified abdominal injuries and results of transaminase, amylase, and lipase testing. Screening studies were compared by using basic test characteristics (sensitivity, specificity) and the area under the receiver operating characteristic curve. RESULTS: Abdominal injuries were identified in 82 of 2890 subjects (2.8%; 95% confidence interval: 2.3%-3.5%). Hepatic transaminases were obtained in 1538 (53%) subjects. Hepatic transaminases had an area under the receiver operating characteristic curve of 0.87. A threshold of 80 IU/L yielded sensitivity of 83.8% and specificity of 83.1%. The areas under the curve for amylase and lipase were 0.67 and 0.72, respectively. CONCLUSIONS: Children evaluated for physical abuse with transaminase levels >80 IU/L should undergo definitive testing for abdominal injury.

Prevalence of abusive injuries in siblings and household contacts of physically abused children.

OBJECTIVE: Siblings and other children who share a home with a physically abused child are thought to be at high risk for abuse, but rates of injury in these contact children are unknown and screening of contacts is highly variable. Our objective was to determine the prevalence of abusive injuries identified by a common screening protocol among contacts of physically abused children. METHODS: This is an observational, multicenter cross-sectional study of children evaluated for physical abuse, and their contacts, by 20 US child abuse teams who used a common screening protocol for the contacts of physically abused children with serious injuries. Contacts underwent physical examination if they were <5 years old, physical examination and skeletal survey (SS) if they were <24 months old, and physical examination, SS, and neuroimaging if they were <6 months old. RESULTS: Protocol-indicated SS identified at least 1 abusive fracture in 16 of 134 contacts (11.9%, 95% confidence interval [CI] 7.5-18.5) <24 months of age. None of these fractures had associated findings on physical examination. No injuries were identified by neuroimaging in 19 of 25 eligible contacts (0.0%, 95% CI 0.0-13.7). Twins were at substantially increased risk of fracture relative to nontwin contacts (odds ratio 20.1, 95% CI 5.8-69.9). CONCLUSIONS: SS should be obtained in the contacts of injured, abused children for contacts who are <24 months old, regardless of physical examination findings. Twins are at higher risk of abusive fractures relative to nontwin contacts.

Hypothalamic expression of Eap1 is not directly controlled by ovarian steroids.

A gene termed EAP1 (enhanced at puberty 1) was recently identified as a transcriptional regulator of female neuroendocrine reproductive function. We have now used in vivo and in vitro assays, and the female rat as an animal model, to determine whether Eap1 gene expression is regulated by ovarian steroids. Eap1 mRNA abundance decreases in both the hypothalamus and cerebral cortex during the infantile-juvenile phases of development, but it increases selectively in the hypothalamus at puberty, suggesting that in contrast to the general decline in expression observed in immature animals, the region-specific increase in Eap1 mRNA levels that occurs at puberty might be elicited by ovarian steroids. This is, however, not the case, because hypothalamic Eap1 mRNA levels increase at the expected time of puberty in rats ovariectomized at the beginning of the juvenile period. Although a subpopulation of EAP1-containing cells in the medial basal hypothalamus (MBH) and preoptic area express estrogen receptor-alpha (ERalpha), the 5'-flanking region of the rat Eap1 (rEap1) gene does not contain a complete estrogen-responsive element, and no such estrogen-responsive element is detected within 100 kb of the rEap1 locus. Functional promoter assays showed that neither estradiol (E(2)) alone nor a combination of E(2) plus progesterone increases rEap1 gene transcription. Likewise, E(2) administered to ovariectomized immature rats elicited a robust surge of LH but increased neither preoptic area nor MBH Eap1 mRNA levels. E(2)/progesterone-treated rats showed a massive elevation in plasma LH but only a modest increase in Eap1 mRNA levels, limited to the MBH. These results indicate that hypothalamic Eap1 expression is not directly controlled by ovarian steroids and suggest that Eap1 expression increases at puberty driven by ovary-independent, centrally initiated events.

Has this prepubertal girl been sexually abused?

CONTEXT: The legal and social sequelae of interpreting genital findings as indicative of sexual abuse are significant. While the absence of genital trauma does not rule out sexual abuse, the physical examination can identify genital findings compatible with sexual abuse. OBJECTIVES: To determine the diagnostic utility of the genital examination in prepubertal girls for identifying nonacute sexual abuse. DATA SOURCES: Published articles (1966-October 2008) that appeared in the MEDLINE database and were indexed under the search terms of child abuse, sexual or child abuse and either physical examination; genitalia; female, diagnosis; or sensitivity and specificity; and bibliographies of retrieved articles and textbooks. STUDY SELECTION: Three of the authors independently reviewed titles of articles obtained from MEDLINE and selected articles for full-text review. DATA EXTRACTION: Two authors independently abstracted data to calculate sensitivity, specificity, and likelihood ratios for the diagnosis of nonacute genital trauma caused by sexual abuse in prepubertal girls. RESULTS: Data were not pooled due to study heterogeneity. The presence of vaginal discharge (positive likelihood ratio, 2.7; 95% confidence interval, 1.2-6.0) indicates an increased likelihood of sexual abuse. In the posterior hymen, hymenal transections, deep notches, and perforations prompt concerns for genital trauma from sexual abuse, but the sensitivity is unknown. Without a history of genital trauma from sexual abuse, the majority of prepubertal girls will not have a hymenal transection (specificity close to 100%). CONCLUSIONS: Vaginal discharge as well as posterior hymenal transections, deep notches, and perforations raise the suspicion for sexual abuse in a prepubertal girl, but the findings do not independently confirm the diagnosis. Given the broad 95% confidence intervals around the likelihood ratios for the presence of findings along with the low or unknown sensitivity of all physical examination findings evaluated, the physical examination cannot independently confirm or exclude nonacute sexual abuse as the cause of genital trauma in prepubertal girls.

Guidelines for medical care of children who may have been sexually abused.

BACKGROUND: Children who may have been sexually abused are examined in many different settings by medical providers with variable levels of education and experience in this special area of practice. Therefore, there is a need for a consistent evidence-based approach that is agreed upon by medical experts. OBJECTIVES: To develop and provide guidelines and recommendations for performing and interpreting findings of the medical evaluation of children referred for sexual abuse medical evaluations, and to provide guidelines for the education, oversight, and peer review process for clinicians who provide assessments for suspected child sexual abuse. METHODS: Participation from medical providers was solicited through postings on the Internet list-serves administered by Cornell University (Special Interest Group in Child Abuse), and by the Ray E. Helfer Society, an honorary society for physician specialists in child abuse diagnosis and treatment. The guidelines were developed through review and critique of published research studies, discussions in focus group meetings at child abuse medical conferences, and ongoing communication leading to revision of draft documents. RESULTS: Groups of 10 to 40 physician experts met at child abuse conferences between January 2002 and January 2005 to revise the table summarizing the interpretation of physical and laboratory findings in suspected child sexual abuse and to develop guidelines for medical care for sexually abused children. Between January and December 2005, the guidelines were expanded and revised. CONCLUSIONS: The guidelines presented here reflect the current knowledge, recommended clinical approaches, and required competencies in the field of child sexual abuse medical evaluation.
