CONFLICT OF INTEREST: NONE DECLAREDIntroductionTeratomas are derived from embryonic tissues that are typically found in the gonadal and sacrococcygeal regions of adults and children. Primary teratomas in the retroperitoneum are very rare in infant and primary adrenal teratomas are extremely rare. Early diagnosis and surgical resection are important for effective treatment.Case reportWe report here the case of a histologically unusual adrenal teratomas detected on computed tomography during the workup of abdominal distension 3-mounth-old male infant. The evaluation and treatment of this condition and a review of the literature are included in this paper.

This study aims to determine and evaluate the learning barriers of high school students in Turkey. These barriers are examined from various emotional and motivational dimensions, such as selfefficacy, self-regulation, deficiency of professional/parental/sibling support and consultancy, learning environment, fear of failure, rejection, criticism and judgment and embarrassment. These dimensions in learning barriers influence all kinds of measurements to be carried on about students. Therefore, describing and revealing them may help handle the measurement outcomes gathered from students in different ways. The study employed a descriptive research methodology to collect data from all regions of Turkey. In this study, six scales were administered to the participants, who are 2175 high school students from the ninth, tenth and eleventh grades attending high schools. The results of the study suggest that students have some difficulty in planning how to study, which is a self-regulative skill. The participants' views mostly show that teacher support can make a strong learning barrier. Parental support is also another learning barrier. Furthermore, it was found out that the learning environment in classrooms did not motivate students to learn.
