Turkish Journal of Medical Sciences

Background/aim: Epilepsy is a chronic neurological disorder that significantly affects psychosocial functioning, self-perception, and quality of life. Emerging evidence suggests that posttraumatic stress (PTS) symptoms may be more prevalent in individuals with epilepsy than previously recognized, particularly following seizure-related experiences perceived as traumatic. The aim of this study was to evaluate short- and long-term PTS levels in individuals with newly diagnosed epilepsy and examine their associations with anxiety, depression, early maladaptive schemas, and quality of life.

Materials and methods: In this prospective study, 31 individuals with newly diagnosed epilepsy were enrolled. Participants completed a sociodemographic data form, the Post-Traumatic Stress …

Turkish Journal of Medical Sciences

Background/aim: Axillary lymph node (ALN) status is a major prognostic factor in breast cancer and influences both survival outcomes and treatment planning. Noninvasive predictors of nodal metastasis are of clinical interest. Tumor-to-skin distance (TSD) has been proposed as a potential anatomical marker; however, standardized data based on magnetic resonance imaging (MRI) remain limited.

Materials and methods: This retrospective study included 98 female patients with pathologically confirmed breast cancer who underwent preoperative breast MRI between 2020 and 2025. Patients with prior breast or axillary surgery, distant metastasis, multifocal or multicentric disease, or inadequate MRI quality were excluded. TSD was measured on …
