The effects of sexual abuse on female adolescent brain structures.

Objective: Sexual abuse (SA) is known for its effects on brain structures in adolescents. We aimed to explore if SA has any effect on limbic and prefrontal cortex (PFC) structures. We hypothesized that children with SA would have a thinner PFC with larger amygdala and hippocampus that lead to aberrations in threat detection, orientation and response circuit; that would be highly adaptive in a dangerous environment in the short term. Method: We included 57 SA and 33 healthy control (HC) female participants. In addition to psychiatric evaluation, we acquired 3 T MR images from all participants. We compared prefrontal cortical thicknesses, hippocampus and amygdala volumes between groups. Results: The age and education levels of study groups were matched, however, IQ scores and socioeconomic status (SES) scores of the SA group were lower than the controls. Total CTQ scores of the SA group were higher than the HC. Nevertheless, the mean value of sexual abuse scores was above the cut-off scores only for the SA participants. SA participants had larger right and left hippocampus and right amygdala volumes than the controls. SA group had reduced inferior frontal gyrus cortical thickness (T=3.5, p<0.01, cluster size=694 mm2, x=51 y=-30 z=6) than HC group. None of the structural findings were correlated with total or sexual abuse CTQ scores. Conclusion: Children with SA history has structural abnormalities in threat detection, orientation and response circuit. SA victims with no psychiatric diagnosis have a high probability of psychiatric problems with a possible contribution of these aberrations. SA cases that do not have a diagnosis must not be overlooked as they may have structural changes in emotion related brain regions. Careful follow-up is needed for all of all SA cases.

[Relationship between the Psychiatric Symptoms in Expecting Parents and Postpartum Depression and Infantile Colic: A Multicenter Follow up Study]. / Anne ve Baba Adaylarinda Psikiyatrik Belirtiler ile Dogum Sonrasi Depresyon ve Infantil Kolik Arasi Iliski: Çok Merkezli Bir Takip Çalismasi.

OBJECTIVE: The aim of this study is to evaluate the relationship between postpartum depression (PPD), infantile colic (IC) and different psychosocial variables, psychiatric symptoms, attachment style and perceived social support in expecting parents. METHOD: Two hundred forty five expecting mothers and 150 expecting fathers were first interviewed between the 22-34 weeks of pregnancy. Sociodemografic data form, Adult Attachment Style Scale (AASS), State Anxiety Inventory (SAI), Edinburgh Postnatal Depression Scale (EPDS), Multidimensional Scale of Perceived Social Support (MSPSS) and Brief Symptom Inventory (BSI) were filled out by each expecting parent. Second interview was conducted between the postpartum 4-24 weeks. Data form consisting health, nutrition, sleep and crying problems of the infant and EPDS and SAI were filled out by mothers and SAI by fathers. RESULTS: One in every four mothers had PPD symptoms above the threshold on EPDS. Maternal and paternal insecure attachment style, maternal psychiatric symptoms and postpartum anxiety level were found to be the predictors of PPD. One in every five infants had IC and maternal education level, hostility score and PPD symptoms along with paternal insecure attachment style and psychiatric symptoms were the main predictors of IC. CONCLUSION: Results about PPD and IC regarding maternal variables are consistent with the literature. In addition, paternal insecure attachment style is found to be an important risk factor for both PPD and IC. Fathers should also be included in further studies exploring PPD or IC.
