Patients who underwent CP treatment in between January 2015 and January 2020 were evaluated retrospectively, using prospectively collected data. The patients were divided into simple and complicated groups. The groups were assigned depending on the number of sinuses and clinical presentation. The groups were compared in terms of age, sex, number of sessions, cost analysis, body mass index (BMI), recurrence, time resolution, cosmetic results, results /improvement, and complications. This study included 54 patients: 28 (52%) girls and 26 (48%) boys. The mean number of sinuses was 2.4. Symptoms included discharge in 50 (92%) patients, and pain in 42 (78%) patients. Fifty (93%) patients experienced mild pain during the procedure, whereas four (7%) patients had moderate pain. The mean number of CP sessions was 2.9; mean numbers of CP sessions were 2.2 and 4.2 in the Simple and Complicated groups. In total, 5 of 54 patients (9%) had recurrence.At the end of treatment, therapeutic success was achieved in 49 of 54 (91%) patients: 31 of 33 (94%) patients in the Simple group and 18 of 21 patients (86%) in the complicated group. The mean treatment cost for the whole cohort was $17.40. One patient (2%) presented with moderate skin burns. Cosmesis was deemed acceptable by patients, although there was evidence of minor skin burns following the procedure. The findings showed that the CP procedure was advantageous for treatment of PSD, because it was minimally invasive, cost-effective, provided good cosmesis, and had a high success rate and low complication rate. Furthermore, it did not require prior examination, and could be performed under local anesthesia. Therefore, the CP procedure may be useful as a first-line treatment option in children with PSD.

Water and reverse salt flux properties of the obtained membrane were investigated by applying pressure in addition to the osmotic forces. Surface characterization of the membrane was carried out by Fourier-transform infrared spectroscopy (FTIR) and scanning electron microscope (SEM) analyses and flux performance tests were performed in both cross flow and submerged membrane setups. Applying pressure from the feed to the concentrate side had significant effects on the water and salt fluxes. Higher pressure differences between the feed and concentrate sides resulted in unexpected high water fluxes up to 500 Lm À2 h À1 (LMH). Besides, the pressure helps to transfer the salt content of feed water into the concentrate side, differently from the osmotic process preventing the salinity build-up at the feed side. PA coated TuEN membrane operated under pressure will exhibit a favorable solution in water/wastewater treatment applications, especially for membrane bioreactors (MBR) in terms of preventing salt accumulation in the bioreactor, decreasing the membrane fouling, increasing the volume of product water, and enabling the concentrate management.

Rats were randomly assigned to 3 groups of 10 rats. The absence of adhesion was confirmed via laparotomy. Adhesion group: The cecum was removed from the abdomen and scraped with a dry gauze bandage until petechial hemorrhagic foci developed. Cordycepin group: The same surgical procedure was performed as in the adhesion group, and 10 mg/kg cordycepin was administered intraperitoneally. After 15 days, the rats were sacrificed humanely via cardiac blood withdrawal under anesthesia. The rats were then analyzed morphologically and histopathologically, and hydroxyproline (OH-p) and malondialdehyde (MDA) levels were measured. Macroscopic analysis revealed significantly less adhesion in the cordycepin group than in the adhesion group (p<0.01). Furthermore, significant histopathological improvement was also evident in the cordycepin group compared to the adhesion group (p<0.0...

Materials and methods: Forty Wistar albino rats were randomly divided into four groups, as follows: group one, control (C); group two, torsion and ischemia (I); group three: detorsion with ischemia-reperfusion (IR); and group four, detorsion/cordycepin. The rats were then analyzed macromorphologically and histopathologically, and blood tests were performed. Specifically, the total oxidant status (TOS) and total antioxidant status (TAS) were determined, and malondialdehyde (MDA), tumor necrosis factor (TNF)-α, interleukin (IL)-6, and IL-1β levels were analyzed. In addition, pyknotic nuclei, spermatozoa, edema, and hemorrhage were assessed. Results: When the IR and cordycepin groups were compared with the other groups, there was a statistically significant decrease in TNF-α and MDA levels (p < 0.05). Increased TAS levels were observed in the cordycepin group compared with the control group. TOS levels were significantly increased in the I and IR groups, but decreased in the cordycepin group (p < 0.05). Similar effects were observed in tissue biochemistry analysis. Histopathological evaluations revealed that the spermatozoa count was decreased in the I and IR groups. However, there was an increase in the cordycepin group, as well as a statistically significant difference between the IR and cordycepin groups (p < 0.01). Finally, edema and inflammation were increased in the I and IR groups, but decreased in the cordycepin group. Conclusions: Histological and biochemical findings revealed that cordycepin protected against IR-induced testicular injury.

METHODS: Thirty rats were divided into three groups and underwent midline laparotomy under 35 mg/kg ketamine and 5 mg/kg xylazine anaesthesia. In group 1 (n=10), the sham operation group, the abdominal walls were closed without any process. In group 2 (n=10), the control group, the antimesenteric border of the ceacum and the corresponding parietal peritoneum were abraded with dry sterile gauze. In group 3 (n=10), the EE group, 2.5 mg/kg dose of EE was administered as intraperitoneally to the rats after abrasion. All rats were sacrificed on postoperative day 15. Samples were obtained RESULTS: The adhesion score was significantly decreased in the EE group (p=0.001) in comparison with the control group. Microscopically, the EE and sham groups were significantly lower than that of the control group (p<0.001 and p=0.000, respectively). Furthermore, the measurement of tissue levels of hydroxyproline was significantly lower in the sham and EE groups compared to the control group (sham group: 47.6 ± 10.6, EE group: 62.9 ± 9.7, Control group: 84.2 ± 22.1 mg /L/g-tissue). CONCLUSION: The grade and severity of abdominal adhesion could be significantly reduced through administered Ecballium elaterium and therefore be a suitable anti-inflammatory agent for the prevention of postoperative peritoneal adhesion in the future.

The aim of this study was to investigate the potential effect of silybin, a potent antioxidant, on L-arginine-induced acute pancreatitis in an experimental rat model. Material/Methods: Forty female Wistar Albino rats were divided into 5 groups as follows: Group 1 (C): control group (n=8), Group 2 (SL): silybin group (n=8), Group 3 (LA): acute pancreatitis group (n=8), Group 4 (SLLA): prophylaxis group (n=8), and Group 5 (LASL): treatment group (n=8). Group C (control) received 2 intraperitoneal (i.p.) injections of physiological saline at an interval of 1 h. Group SL received only a single i.p. injection of silybin. The SLLA group received a single i.p. injection of silybin before the induction of acute pancreatitis with L-arginine, whereas the LASL group received the same injection after the induction of acute pancreatitis with L-arginine. Pancreatic tissues were histopathologically examined. Levels of amylase and oxidative stress markers (total oxidant status and total anti-oxidant status) were determined in the blood samples. Oxidative stress index was calculated. Results: In comparison to the LA, the prophylaxis and treatment groups showed significant improvements in serum oxidative stress parameters (p=0.001 and p=0.005, respectively). Histopathological analysis showed that the treatment group had significant improvements in edema scores only (p=0.006), whereas the prophylaxis group had the same improvements in inflammation and necrosis scores as well as in total scores (p=0.004, 0.006, and 0.004, respectively). Conclusions: When used for prophylactic rather than therapeutic purposes, silybin ameliorates serum oxidative stress parameters and improves histopathological results via its antioxidant and anti-inflammatory properties.

Materials and methods We conducted a retrospective review of the medical records of 96 patients who had been treated for GI perforation between January 2000 and October 2015. Data were collected and organised according to the following categories: general patient information, age, gender, hospitalisation period, trauma mechanisms, concomitant injuries, radiological assessment, diagnosis and treatment methods, treatment forms, and complications. The cases were divided into two groups, blunt and penetrating traumas, and the patients within each group were compared. Colorectal trauma cases were not included in this study. Patients suspected of a GI perforation were assessed by standing plain abdominal radiograph (SPAR) and ultrasound scan (US). Patients who had a normal SPAR, and showed free or viscous fluid in the abdomen on US underwent computed tomography (CT) scanning. Surgery was performed if patients displayed free air in the abdomen on a SPAR or CT scan, showed viscous fluid without any additional injury, provided normal radiological images but displayed signs of peritonitis, or were clinically unstable. The patients were scored according to the Injury Severity Score (ISS) system. Results In total, 96 patients, with an average age of 10.3 ± 4 years (1-17 years) and diagnosed with a GI perforation, were reviewed retrospectively. The patients included 88 (91 %) males and 8 (9 %) females. The presence of free air on SPAR was detected in 42 (52 %) patients, whereas no free air was detected in 39 (48 %) patients. Non-specific significant findings were detected in 45 (76 %) out of 59 patients by USS, and in 78 % of patients by CT (viscous fluid, fluid, free air). The most affected organ was the ileum, which was detected in 37 (39 %) patients. Primary repair was performed on 71 (74 %) patients, while resection was performed on 22 (23 %); 3 (3 %) patients underwent an ostomy. Ten (10 %) patients experienced complications and five (5 %) patients died. The ISS scores for blunt and penetrating traumas were 14, 15 and no significant difference was detected between the scores (p [ 0.05). Conclusions Although the complication rate for patients with penetrating trauma was higher than for those with blunt trauma, the rate of mortality increased in patients with blunt trauma. Free air may not be detected by SPAR even if a GI perforation exists. Since diagnostic challenges may increase the rate of mortality and morbidity in GI perforations, we believe that a combination of radiological imaging and rapid abdominal examination is important in cases where SPAR cannot detect free air.

It has been proposed to reduce the high energy consumption in the conventional MBR, has lower membrane fouling propensity, and produce higher quality water. Moreover, RO process can be used after FOMBR to reconcentrate the diluted DS to be used for FO again. Besides significant advantages, when compared to conventional MBRs; lower water flux, concentration polarization, and salt accumulation because of high retention of FO in the bioreactor still remains as major drawbacks and challenges of FOMBR systems that need to be solved. In the last few years, many advances in development of FOMBR are stated to overcome the drawbacks of the system. The researches focused on manufacturing of high performance FO membranes and orientation, utilizing various different draw solutions providing required osmotic pressure and minimum reverse salt flux, a...

This study investigated the use of radiological and laboratory testing for predicting the development of pancreatic pseudocysts after trauma. Materials and methods The clinical records of all pediatric patients presenting with pancreatic trauma between January 2003 and December 2014 were reviewed retrospectively. Patients with American Association for the Surgery of Trauma (AAST) scores of Grade 3-5 were enrolled. The patients were divided into groups that developed [Group 1 (n = 20)] and did not develop [Group 2 (n = 18)] PC. The patients were evaluated in terms of their baseline characteristics, additional injuries, Injury Severity Score (ISS), pancreatic injury site, blood amylase levels 2 h and 10-15 days after the trauma, clinical presentation, and duration of intensive care unit (ICU) stay. Findings We followed 38 patients. Of the patients in Group 1, 70 % had an injury to the tail of the pancreas. The ISS trauma scores and durations of hospitalization and ICU stay were significantly greater in Group 2 (p \ 0.05
Cases of neonatal gastrointestinal system (GIS) obstruction are quite complex for pediatric surge... more Cases of neonatal gastrointestinal system (GIS) obstruction are quite complex for pediatric surgery clinics. A rare cause of intestinal obstruction is the duplication cyst (DC). A three-day-old male patient presented at our clinic with a history of abdominal distension and bilious vomiting on the second day following birth. Although pathology had not yet been determined from observation and examination, surgery was performed when the patient could not tolerate oral feeding. An ileal DC forming an incomplete obstruction was observed. Ileoileal anastomosis was performed on the patient. Because DCs can present with different clinical symptoms, it is quite difficult to diagnose them in neonate patients. Lacking an imaging method that can provide an exact diagnosis, the diagnostic laparotomy is a suitable approach for both diagnosis and treatment to avoid delays in treatment.

However, when it occurs, it tends to have a high rate of complications. This is a case report of a 3-year-old child who swallowed multiple magnetic toys, subsequently developing jejunoileal perforation and volvulus. This case report indicates that it is best to surgically remove multiple ingested magnets without delay to avoid intestinal perforation, fistula, and other complications such as volvulus.

Materials and methods: Forty Wistar albino rats were randomly divided into four groups, as follows: group one, control (C); group two, torsion and ischemia (I); group three: detorsion with ischemia-reperfusion (IR); and group four, detorsion/cordycepin. The rats were then analyzed macromorphologically and histopathologically, and blood tests were performed. Specifically, the total oxidant status (TOS) and total antioxidant status (TAS) were determined, and malondialdehyde (MDA), tumor necrosis factor (TNF)-α, interleukin (IL)-6, and IL-1β levels were analyzed. In addition, pyknotic nuclei, spermatozoa, edema, and hemorrhage were assessed. Results: When the IR and cordycepin groups were compared with the other groups, there was a statistically significant decrease in TNF-α and MDA levels (p < 0.05). Increased TAS levels were observed in the cordycepin group compared with the control group. TOS levels were significantly increased in the I and IR groups, but decreased in the cordycepin group (p < 0.05). Similar effects were observed in tissue biochemistry analysis. Histopathological evaluations revealed that the spermatozoa count was decreased in the I and IR groups. However, there was an increase in the cordycepin group, as well as a statistically significant difference between the IR and cordycepin groups (p < 0.01). Finally, edema and inflammation were increased in the I and IR groups, but decreased in the cordycepin group. Conclusions: Histological and biochemical findings revealed that cordycepin protected against IR-induced testicular injury.

METHODS: Thirty rats were divided into three groups and underwent midline laparotomy under 35 mg/kg ketamine and 5 mg/kg xylazine anaesthesia. In group 1 (n=10), the sham operation group, the abdominal walls were closed without any process. In group 2 (n=10), the control group, the antimesenteric border of the ceacum and the corresponding parietal peritoneum were abraded with dry sterile gauze. In group 3 (n=10), the EE group, 2.5 mg/kg dose of EE was administered as intraperitoneally to the rats after abrasion. All rats were sacrificed on postoperative day 15. Samples were obtained RESULTS: The adhesion score was significantly decreased in the EE group (p=0.001) in comparison with the control group. Microscopically, the EE and sham groups were significantly lower than that of the control group (p<0.001 and p=0.000, respectively). Furthermore, the measurement of tissue levels of hydroxyproline was significantly lower in the sham and EE groups compared to the control group (sham group: 47.6 ± 10.6, EE group: 62.9 ± 9.7, Control group: 84.2 ± 22.1 mg /L/g-tissue). CONCLUSION: The grade and severity of abdominal adhesion could be significantly reduced through administered Ecballium elaterium and therefore be a suitable anti-inflammatory agent for the prevention of postoperative peritoneal adhesion in the future.

The aim of this study was to investigate the potential effect of silybin, a potent antioxidant, on L-arginine-induced acute pancreatitis in an experimental rat model. Material/Methods: Forty female Wistar Albino rats were divided into 5 groups as follows: Group 1 (C): control group (n=8), Group 2 (SL): silybin group (n=8), Group 3 (LA): acute pancreatitis group (n=8), Group 4 (SLLA): prophylaxis group (n=8), and Group 5 (LASL): treatment group (n=8). Group C (control) received 2 intraperitoneal (i.p.) injections of physiological saline at an interval of 1 h. Group SL received only a single i.p. injection of silybin. The SLLA group received a single i.p. injection of silybin before the induction of acute pancreatitis with L-arginine, whereas the LASL group received the same injection after the induction of acute pancreatitis with L-arginine. Pancreatic tissues were histopathologically examined. Levels of amylase and oxidative stress markers (total oxidant status and total anti-oxidant status) were determined in the blood samples. Oxidative stress index was calculated. Results: In comparison to the LA, the prophylaxis and treatment groups showed significant improvements in serum oxidative stress parameters (p=0.001 and p=0.005, respectively). Histopathological analysis showed that the treatment group had significant improvements in edema scores only (p=0.006), whereas the prophylaxis group had the same improvements in inflammation and necrosis scores as well as in total scores (p=0.004, 0.006, and 0.004, respectively). Conclusions: When used for prophylactic rather than therapeutic purposes, silybin ameliorates serum oxidative stress parameters and improves histopathological results via its antioxidant and anti-inflammatory properties.

Materials and methods We conducted a retrospective review of the medical records of 96 patients who had been treated for GI perforation between January 2000 and October 2015. Data were collected and organised according to the following categories: general patient information, age, gender, hospitalisation period, trauma mechanisms, concomitant injuries, radiological assessment, diagnosis and treatment methods, treatment forms, and complications. The cases were divided into two groups, blunt and penetrating traumas, and the patients within each group were compared. Colorectal trauma cases were not included in this study. Patients suspected of a GI perforation were assessed by standing plain abdominal radiograph (SPAR) and ultrasound scan (US). Patients who had a normal SPAR, and showed free or viscous fluid in the abdomen on US underwent computed tomography (CT) scanning. Surgery was performed if patients displayed free air in the abdomen on a SPAR or CT scan, showed viscous fluid without any additional injury, provided normal radiological images but displayed signs of peritonitis, or were clinically unstable. The patients were scored according to the Injury Severity Score (ISS) system. Results In total, 96 patients, with an average age of 10.3 ± 4 years (1-17 years) and diagnosed with a GI perforation, were reviewed retrospectively. The patients included 88 (91 %) males and 8 (9 %) females. The presence of free air on SPAR was detected in 42 (52 %) patients, whereas no free air was detected in 39 (48 %) patients. Non-specific significant findings were detected in 45 (76 %) out of 59 patients by USS, and in 78 % of patients by CT (viscous fluid, fluid, free air). The most affected organ was the ileum, which was detected in 37 (39 %) patients. Primary repair was performed on 71 (74 %) patients, while resection was performed on 22 (23 %); 3 (3 %) patients underwent an ostomy. Ten (10 %) patients experienced complications and five (5 %) patients died. The ISS scores for blunt and penetrating traumas were 14, 15 and no significant difference was detected between the scores (p [ 0.05). Conclusions Although the complication rate for patients with penetrating trauma was higher than for those with blunt trauma, the rate of mortality increased in patients with blunt trauma. Free air may not be detected by SPAR even if a GI perforation exists. Since diagnostic challenges may increase the rate of mortality and morbidity in GI perforations, we believe that a combination of radiological imaging and rapid abdominal examination is important in cases where SPAR cannot detect free air.

It has been proposed to reduce the high energy consumption in the conventional MBR, has lower membrane fouling propensity, and produce higher quality water. Moreover, RO process can be used after FOMBR to reconcentrate the diluted DS to be used for FO again. Besides significant advantages, when compared to conventional MBRs; lower water flux, concentration polarization, and salt accumulation because of high retention of FO in the bioreactor still remains as major drawbacks and challenges of FOMBR systems that need to be solved. In the last few years, many advances in development of FOMBR are stated to overcome the drawbacks of the system. The researches focused on manufacturing of high performance FO membranes and orientation, utilizing various different draw solutions providing required osmotic pressure and minimum reverse salt flux, a...

This study investigated the use of radiological and laboratory testing for predicting the development of pancreatic pseudocysts after trauma. Materials and methods The clinical records of all pediatric patients presenting with pancreatic trauma between January 2003 and December 2014 were reviewed retrospectively. Patients with American Association for the Surgery of Trauma (AAST) scores of Grade 3-5 were enrolled. The patients were divided into groups that developed [Group 1 (n = 20)] and did not develop [Group 2 (n = 18)] PC. The patients were evaluated in terms of their baseline characteristics, additional injuries, Injury Severity Score (ISS), pancreatic injury site, blood amylase levels 2 h and 10-15 days after the trauma, clinical presentation, and duration of intensive care unit (ICU) stay. Findings We followed 38 patients. Of the patients in Group 1, 70 % had an injury to the tail of the pancreas. The ISS trauma scores and durations of hospitalization and ICU stay were significantly greater in Group 2 (p \ 0.05

A rare cause of intestinal obstruction is the duplication cyst (DC). A three-day-old male patient presented at our clinic with a history of abdominal distension and bilious vomiting on the second day following birth. Although pathology had not yet been determined from observation and examination, surgery was performed when the patient could not tolerate oral feeding. An ileal DC forming an incomplete obstruction was observed. Ileoileal anastomosis was performed on the patient. Because DCs can present with different clinical symptoms, it is quite difficult to diagnose them in neonate patients. Lacking an imaging method that can provide an exact diagnosis, the diagnostic laparotomy is a suitable approach for both diagnosis and treatment to avoid delays in treatment.

However, when it occurs, it tends to have a high rate of complications. This is a case report of a 3-year-old child who swallowed multiple magnetic toys, subsequently developing jejunoileal perforation and volvulus. This case report indicates that it is best to surgically remove multiple ingested magnets without delay to avoid intestinal perforation, fistula, and other complications such as volvulus.

We present the case of a 1-year-old male child with a congenital anterior urethral diverticulum. This condition can lead to obstructive lower urinary tract symptoms and urosepsis. The clinical presentation, diagnosis, and management of this rare condition are discussed in this report. The diagnosis was made using retrograde urethrography. Patient was treated with open diverticulectomy and urethroplasty.

In this article was presented a case of urethral duplication in an 8-month-old male child. The malformation was characterized by the presence of continent hypospadic and normal apical urethra. Retrograde urethrogram through both urethral tracts simultaneously revealed the malformation as Effmann Type II A-2. The accessory ventral urethra was excised without complication.

Although its excision is recommended when found incidentally during inguinal surgical procedures, routine exploration is not indicated for the detection of its presence. Here, we present eight cases of ectopic adrenal tissue in pediatric patients who underwent orchidopexy.
