Objective: In this study with the experimental model of primary repair of esophageal atresia(EA), we investigated the effects of the epidermal growth factor(EGF) on wound healing in the anastomosis of EA. Materials and methods: Forty rabbits that were performed a resection of a 1-cm segment of the cervical esophagus followed by the end-to-end anastomosis were divided into four groups. Group I (7-day group) and III (21-day group), the control groups, had no EGF applied to the anastomosis. In group II (7-day group) and group III (21-day group), all around the anastomoses were locally covered with 100 mu g/kg EGF. Group 1, 2 and 3, 4 were sacrificed on the 7th and 21st day, respectively. We investigated and compared with bursting pressure, vascularization around the anastomotic line by histopathology, inflammation, and fibroblast granulation as well as hydroxyproline level by biochemical. Results: No significant difference was found at vascularization and inflammation between all of the groups (p > 0.05). Considering the critical parameters of the groups, at bursting pressure difference was found between group 1 and 2 as well as 3 and (p < 0.05). At fibroblast granulation and hydroxyproline level, no difference was found between group 1 and 2 (p > 0.05) but the difference between group 3 and 4 (p < 0.05). Conclusion: EGF might be useful in preventing anastomotic leakage of esophageal atresia in primary anastomosis of esophageal atresia by accelerating wound healing process and increasing the stability of the anastomotic line.

Objective: The aim of our study was to investigate subclinical cardiac disturbances in patients with symptoms due to adenotonsillar hypertrophy (ATH) and the impact of adenotonsillectomy (AT) using conventional and novel echocardiographic measures. Material and methods: Thirty patients with grade 3 or 4 ATH (mean age: 7.86 ± 3.83 years; 10 females) and 30 healthy, age- and sex-matched volunteers (mean age, 8 ± 2.77; 14 females) were enrolled in the study. In addition to conventional two-dimensional and Doppler echocardiographic parameters, tissue Doppler parameters, including myocardial performance indices (MPIs) of both the right (RV) and left ventricle (LV), were studied. The severity of obstructive sleep apnea (OSA) was determined using the OSA-18 health quality questionnaire. The OSA-18 questionnaire and echocardiographic examination were repeated after AT in patients with ATH. Results: The total OSA-18 scores for the control, preoperative, and postoperative groups were 39.56 ± 19.98, 80.63 ± 22.32, and 44.10 ± 20.31, respectively. Conventional parameters were not different among the groups. The mean pulmonary artery pressure estimated using the Mahan formula was increased in the ATH group compared with that in the control group (21.72 ± 4.25 vs. 12.43 ± 3.83, respectively; p < 0.001) and significantly improved after AT (21.72 ± 4.25 vs. 16.09 ± 4.53; p < 0.001). The RV MPI was significantly different between the control and ATH groups (0.322 ± 0.052 vs. 0.383 ± 0.079, respectively; p= 0.001). Both the LV and RV MPI significantly improved (0.515 ± 0.066 vs. 0.434 ± 0.052, p < 0.001; and 0.383 ± 0.079 vs. 0.316 ± 0.058, p= 0.018, respectively) after surgery for ATH. Conclusions: Our study revealed that the patients with OSA-specific symptoms due to ATH had higher pulmonary artery pressure and impaired RV function according to novel echocardiographic parameters. Surgery for ATH seems to have an important effect on both LV and RV function.

Objective: This study was semi-experimentally conducted in order to determine knowledge levels of child development students about foreign body aspiration and to explore the effect of the training given to these students about foreign body aspiration upon their knowledge levels. Methods: The research was conducted with a total of 231 students who studied at the department of child development of two high schools and one vocational higher school in Erzincan Province located in the east of Turkiye between May 2011 and February 2012. The data were gathered using a questionnaire form of 38 questions. The training on foreign body aspiration (Power point presentation, video presentation and practice on a dummy) was provided in three phases. For the data evaluation; percentages, chi-square test and Mc Nemar test were used. Results: It was found out in the study that 91.8% of the students did not take any training/course about foreign body aspiration and 55% confronted situations of foreign body aspirations (ear, nose, airway).After the training about foreign body aspiration; it was noted that the number of the students who knew risky behaviors for foreign body aspiration increased and the increase in the number of the students was at the highest level among high schools (p<0.05). It was seen that the training was most effective among the university students in terms of knowing first-aid intervention in case a foreign body would obstruct airway among the children aged. <1 year (p<0.05). Conclusion: It was noted that the training which was applied on the dummy by using visual aids about foreign body aspiration increased the knowledge level of the students. Based on this finding, it may be recommended that nurses should perform their counseling and educator roles more actively for the families and those who are responsible for the baby care about foreign body aspiration by playing a more active role in the health care team.
