Objective: To compare reactive oxygen species (ROS) and antioxidants in internal spermatic vein tissue of men with varicocele and a control group with inguinal hernia. Also to compare the levels of oxidants and antioxidants in infertile and fertile men with varicocele. Patients and Methods: 48 varicocele patients and 12 non-varicocele inguinal hernia patients participated in this study. The varicocele group was again divided into two groups – fertile men with varicocele and infertile men with varicocele. Internal spermatic vein tissue samples were obtained. The level of the malondialdehyde (MDA), an indicator of oxidative stress, and the activities of antioxidant enzymes (defense systems) against oxidative stress such as superoxide dismutase (SOD) and catalase (CAT) were estimated in these tissue samples. Results: The mean level of MDA in the varicocele group was significantly higher than in the hernia group, whereas the levels of antioxidants (SOD and CAT) were significantly lower in the varicocele group than in the hernia group. When compared with the subgroups of the varicocele group, the MDA levels and SOD and CAT activities were significantly higher in the infertile varicocele group than in the fertile varicocele group. Conclusions: Antioxidant enzyme levels generally decrease due to a high consumption in varicocele patients. On the contrary, in our study both MDA and antioxidant enzymes increased in the internal spermatic venous wall of infertile varicocele patients. This situation may be explained by an adaptation against oxidative stress in varicocele, which could be defined as a chronic process.

Background: Clinical experiences emphasize the possible role of parental attitudes and behaviours in shaping stuttering behaviors however, the number of studies in this area is still insufficient. Objective: Our aims were to compare parental attitudes in children with and without stuttering and to determine the effect of parental attitudes on stuttering severity. Methods: We used an age and gender matched case control design with 24 children with stuttering and 22 healthy school children. Demographic information form and Parental Attitude Research Instrument (PARI) were enrolled by the mothers. Results: According to our results; there was a statistically significant difference in parental attitudes of children with and without stuttering. Our results showed that excessive maternal control of the child and the expectations of obedience from the child more frequently observed in parents of the children with stuttering. Also there was a significant positive correlation with the severity of stuttering and excessive maternal control of the child, the expectations of obedience from the child and marital conflict. Discussion: In conclusion, there was an important difference in parental styles of study group and this difference was related to the severity of stuttering. Clinicans should address parental attitudes in this samples.
