“…The enteric string test, typically used to diagnose intestinal parasites, consists of ingestion of a small, dissolvable gelatin capsule containing a string that absorbs stomach fluids [ 12 ]. Because the string could also absorb sputum that has been swallowed, it has been proposed as a technique for obtaining lower respiratory specimens for tuberculosis testing in children.…”

BackgroundThe enteric string test can be used to obtain a specimen for microbiological confirmation of tuberculosis in children, but it is not widely used for this. The aim of this analysis to evaluate this approach in children with tuberculosis symptoms.MethodsWe conducted a cross-sectional study to assess children’s ability to complete the test (feasibility), and self-reported pain (tolerability). We examined caregivers’ and children’s willingness to repeat the procedure (acceptability) and described the diagnostic yield of cultures for diagnostic tools. We stratified estimates by age and compared metrics to those derived for gastric aspirate (GA).ResultsAmong 148 children who attempted the string test, 34% successfully swallowed the capsule. Feasibility was higher among children aged 11–14 than in children 4–10 years (83% vs 22% respectively, p < 0.0001). The string test was better tolerated than GA in both age groups; however, guardians and older children reported higher rates of willingness to repeat GA than the string test (86% vs. 58% in children; 100% vs. 83% in guardians). In 9 children with a positive sputum culture, 6 had a positive string culture. The one children with a positive gastric aspirate culture also had a positive string culture.ConclusionAlthough the string test was generally tolerable and accepted by children and caregivers; feasibility in young children was low. Reducing the capsule size may improve test success rates in younger children.

Child Sexual Abuse Evaluations

Accurate estimates of true and false child sexual abuse evades researchers and the determination of whether sexual abuse has occurred is a complex problem. In recent years, the research community has been polarized over whether child victims of sexual abuse or nonabuse are grossly misidentified, to what degree children are suggestible, and whether false positive or false negative errors create the greatest harm. This chapter describes the scientific‐practitioner model for evaluating allegations of child sexual abuse, a model previously proposed by the author. According to this model, conclusions regarding child sexual abuse are based upon empirically established relationships between data and the behavior in question, rather than on subjective opinions. To address critical issues in these assessments, this chapter reviews two sources for information: published research and the law. Child sexual abuse is defined, focusing on risk factors for abuse and the meaning of symptoms. Studies citing the incidence and prevalence of child sexual abuse are reviewed. Topics include early memories, the impact of stress on memory, and the development of autobiographical memory. Since recall is subjected to the effects of suggestibility, research on this topic is considered. The structure of the assessment interview and a review of the research on the three most frequently used evaluation tools (anatomical dolls, projective instruments, and drawings) is described.
