Acquired Syphilis by Nonsexual Contact in Childhood

Interpretation of medical findings in suspected child sexual abuse: An update for 2023

Health care professionals who examine children who may have been sexually abused need to be able to recognize, and photo-document any physical signs, and to have access to expert reviewers, particularly when signs concerning for sexual abuse are found. Although the general consensus among practitioners is that children will show few signs of sexual abuse on examination, there is considerable variability and rates of positive exam findings among practitioners of different professions, practice settings, and countries. This review will summarize new data and recommendations regarding the interpretation of medical findings and sexually transmitted infections (STIs); assessment and management of pediatric patients presenting with suspected sexual abuse or assault; and testing and treating patients for STIs. Updates to a table listing an approach to the interpretation of medical findings are presented, and reasons for changes are discussed.

Secondary syphilis in a 14-month-old girl and child-to-mother transmission

Syphilis cases in childhood are usually associated with congenital transmission. Acquired transmission is uncommon, and primarily related to sexual abuse or close contact/nursing with infected family members. We here describe a case of syphilis in a 14-month-old girl resulting from intrafamilial infection, with a subsequent transmission to her mother.

Multilocus sequence typing of Treponema pallidum pallidum in children with acquired syphilis by nonsexual contact

Background: There are scarce data of Treponema pallidum subsp. pallidum (TPA) characterization in children with syphilis. Nonsexually acquired transmission (NSAT) of TPA is possible in infants through close contact. Methods: A descriptive study in five families with NSAT of syphilis was conducted. Polymerase chain reaction detection of TPA in pediatric index cases (n = 6) and their relatives (n = 44) were conducted followed by multilocus sequence typing (MLST). Results: TPA was detected in swab samples in 16 cases and 12 were characterized by MLST. Nichols lineage was identified in two of five families and SS14-lineage in three of five. In four families, MLST profiles linked index cases to relatives. Conclusion: This is the first report of TPA characterization in children infected by NSAT.
