The cause of depression in adolescence: peer bullying.

OBJECTIVE: Depression affects adolescents worldwide and often predicts more serious disease manifestations in later lifetimes. Peer victimization or bullying, another form of child abuse, increases symptoms of depression. In this paper, the relationship between peer bullying and depression in adolescence was investigated. SUBJECTS AND METHODS: Each adolescent who was admitted to the adolescent unit completed forms referred to as the 'Depression Scale For Children' and the 'Multidimensional Peer Victimization Scale'. Sociodemographic features and results of the scales' evaluation were studied. SPSS 16.0 program was used for statistical analysis. The p-value below 0.05 was considered statistically significant. RESULTS: 239 adolescents, 120 of whom were male, were investigated. A positive relationship was determined among total and sub-scale scores of peer victimization-determining scale and depression scale scores. A negative relationship was determined between height, weight, age of the child, and sub-scale score of threat/intimidation. Both the total score of the peer victimization-determining scale and sub-scale scores of ridicule, open attack, and relational attack pertaining to patients with depression proved to be significantly higher than in those without depression. CONCLUSIONS: The awareness of educators and parents, notably adolescents, must be raised in regard to peer victimization, and activities for increasing the communicative skills of adolescents and for allowing them to be able to express their emotions should also be performed. Identifying and preventing peer victimization, one of the causes of depression, and launching the treatment process for this are the first steps to be taken in terms of a healthy adulthood.

Protective effects of Silymarin on testicular torsion/detorsion in rats.

OBJECTIVE: The present research aimed to study the possible protective effects of Silymarin on testicular I/R injury in a rat model evaluated through histopathology and biochemical parameters. MATERIALS AND METHODS: This research investigated the impact of Silymarin on IR damage in male Wistar albino rats. Animals were divided into three groups: group 1 (sham), group 2 (IR), and group 3 (IR+Silymarin). RESULTS: There were no notable differences in the levels of malondialdehyde (MDA), myeloperoxidase (MPO), and glutathione (GSH) across the three groups (p=0.260, p=0.486 and p=0.803, respectively). Contrarily, the total antioxidant status (TAS) levels exhibited significant variations between groups (p=0.001). The total oxidant status (TOS) levels also differed significantly between groups (p=0.004). The tissue evaluations uncovered substantial differences in the Johnson score, which is used to gauge testicular damage. A distinct contrast was seen between Group 1 and Group 2, and also between Group 2 and Group 3, with an all-encompassing p-value lower than 0.01. The same significant disparities were found for the percentages of Bax and Annexin V immunostaining (p<0.01 for each), reflecting the inflammation and apoptosis brought about by ischemia-reperfusion and the protective effects of the treatment. CONCLUSIONS: The outcomes of the current investigation showed that Silymarin could be a valuable agent for reducing testicular tissue damage following I/R injury.

Is testicular fixation to the scrotum necessary in patients with undescended testis? A comparative study.

OBJECTIVE: This study aimed to compare the outcome of undescended testicle patients with and without transparenchymal sutures. PATIENTS AND METHODS: Patients were divided into two distinct groups for evaluation: Group 1 (Testicular Fixation +): this group comprised 41 patients who underwent a procedure that involved testicular fixation. Group 2 (Testicular Fixation -): this group included 47 patients who had not undergone any testicular fixation. RESULTS: The age difference between these groups was not statistically meaningful (p>0.05). As for the presence of hypospadias, 2 patients (4.8%) in Group 1 and 3 patients (6.4%) in Group 2 were affected, showing no significant difference (p>0.05). Post-surgical local infection was evident in 9.8% of Group 1 and 8.5% of Group 2 patients, showcasing no significant difference (p>0.05). When assessing recurrence, both groups bore almost identical rates, 7.3% for Group 1 and 6.4% for Group 2 (p>0.05). Atrophy was observed in 2.4% of Group 1 and 2.1% of Group 2, with no marked distinction (p>0.05). CONCLUSIONS: Both groups exhibited similar outcomes, suggesting that no fixation method was also a good option.

A novel scarless laparoscopic method for morgagni hernia repair.

Background: Morgagni hernia (MH) is a rare congenital defect of the diaphragm. Although the various surgical method has been proposed, there is no surgical consensus. Aim: In this study, we aimed to report the outcome of the patients that underwent surgery which is completed using a single port laparoscopic-assisted transabdominal closure of MH. Patients and Methods: This is a retrospective analysis of 18 pediatric patients who underwent novel laparoscopic MH repair at a single tertiary pediatric hospital between March 2018 and December 2020. Results: Of the 18 patients, 72% (n = 13) were male and 28% (n = 5) were female. The symptoms at admission included repeated chest infection (39%), dyspnea (33%), vomiting (17%), and abdominal pain (22%). The colon (78%) was the most frequently herniated organ. Hernias were bilateral, on the left, and on the right in seven, four, and seven cases, respectively. All surgical interventions were completed within 25-50 min. All patients started enteral feeding within 24 hours. All patients were discharged within 1-3 days without any complications. The mean follow-up period was 27 months. Conclusions: In conclusion, our method is characterized by a shorter operation time, early return to feeding, early discharge, excellent cosmetic results, low cost, and low recurrence rate. Further prospective trials are needed to compare our novel scarless technique to other methods.

Progressive transmission of images using MAP detection over channels with memory.

We propose a new maximum a posteriori (MAP) detector, without the need for explicit channel coding, to lessen the impact of communication channel errors on compressed image sources. The MAP detector exploits the spatial correlation in the compressed bitstream as well as the temporal memory in the channel to correct channel errors. We first present a technique for computing the residual redundancy inherent in a compressed grayscale image (compressed using VQ). The performance of the proposed MAP detector is compared to that of a memoryless MAP detector. We also investigate the dependence of the performance on memory characteristics of the Gilbert-Elliott channel as well as average channel error rate. Finally, we study the robustness of the proposed MAP detector's performance to estimation errors.
