Evaluation of Incest Cases: 4-Years Retrospective Study

Analysis of aborted fetal material using autosomal STR markers in forensic cases of sexual assault

Sexual violence represents a widespread social problem associated with serious lifelong consequences. In many cases, an outcome of sexual violence is the victim's unwanted pregnancy, usually ended in an abortion. The objective of this paper is to report five rape cases, including rapes of a minor and young woman, two incest cases and a case of human trafficking for sexual exploitation, where every case resulted in the victim's pregnancy. In each case, pregnancy was terminated in the first trimester or at the beginning of the second trimester in the relevant medical center or clinic. Fresh fetal blood or aborted tissue samples were delivered to our laboratory in order to perform paternity testing for the purpose of proving the crime. DNA extraction using Qiagen Dneasy™ Tissue Kit was optimized according to the sample type. Amplification of autosomal STR (Short Tandem Repeat) markers was performed using the PowerPlex®16 System. In two cases, mixtures of maternal and fetal DNA in the aborted fetal material were found. Using the LRmix Studio v.2.1.5 Software for interpreting DNA mixtures based on a probabilistic model, the likelihoods of maternal contribution and presence of fetal allelic variants inherited from the alleged father/suspect were calculated. Based on these results, we confirmed the presence of assumed fetal fractions (determined before software analysis) in the mixtures. In all cases, positive paternity proved the crime (probabilities of paternity >99.9999%). This cases report once again pointed out the importance of DNA analysis in the process of clarifying and solving forensic cases and demonstrated that the LRmix Studio v.2.1.5 Software can deal with complex cases such as sexual assaults.

An examination of the sociodemographic and psychiatric characteristics of children who have suffered penetrative and non-penetrative sexual abuse in Malatya, Eastern Turkey

Penetrative and nonpenetrative sexual abuse can cause short- and long-term psychiatric problems in victims. This study aimed to examine the sociodemographic characteristics and psychiatric diseases of children in Malatya, eastern Turkey, according to whether the abuse was penetrative or nonpenetrative. A retrospective examination was conducted on the records of 115 cases of sexual abuse that had been referred to judicial authorities from January 1, 2012-July 30, 2019. The subjects were evaluated by a committee formed of 5-7 separate specialized department faculty members. It was determined that 51.3% (n = 59) of the cases had suffered nonpenetrative sexual abuse, and 48.7% (n = 56) had suffered penetrative sexual abuse. The majority of the perpetrators were known to the child from their close environment. A psychiatric diagnosis was made by the committee in 20.3% (n = 12) of the nonpenetrative cases and in 42.9% (n = 24) of the penetrative cases. There was a significant difference between penetrative and nonpenetrative sexual abuse in terms of psychiatric diagnoses. Of the cases of penetrative sexual abuse, 87.5% (n = 14) had attempted suicide. As a result, early diagnosis of sexual abuse, which has devastating effects on mental health in the early and late periods before it penetrates, can reduce the devastating effects on the child. For this reason, it is crucial for doctors, psychologists, social workers, and teachers who work with children to be informed about this issue.

Incestuous childhood sexual abuse between siblings resulting in pregnancy without sexual intercourse

Victims of incest are usually women and children who are mostly girls. The abuse between siblings may remain hidden because of the family's fear of social stigma, though it may result in pregnancy. This article presents a case of incestuous childhood sexual abuse between siblings resulting in pregnancy without intercourse, an event rarely reported in the literature. An 11-year-old girl was brought to the hospital because of a stomachache and was detected pregnancy from examinations. Forensic medicine experts determined that the girl's hymen was still intact and non-elastic in the genital examination. Gynecology and Obstetrics Department confirmed the pregnant compatibility with 14 weeks, 4 days; after ultrasonographic monitoring. She was abused by her 14-year-old brother by rubbing for 1 year and this resulted in pregnancy. During the psychiatric examination, her attitude was negative and symptoms of post-traumatic stress disorder emerged. Medical abortion was applied after psychiatric and gynecological examinations. The girl's brother was confirmed as the biological father after the DNA paternity test was conducted on the fetus. Based on this case, this article aimed to examine the medical, social, and legal problems caused by incestuous childhood sexual abuse and contribute to the literature by emphasizing what forensic medicine and preventive medicine approaches should consider in such cases.
