A rare complication of pediatric liver transplantation: Post-transplant diaphragmatic hernia.

AIM: Acquired post-transplant diaphragmatic hernia (PTDH) is a rare complication of liver transplantation (LT) in children. We aimed to present our experience in PTDH, and a possible causative background is discussed. METHODS: Medical records of patients who had undergone diaphragmatic repair following LT between 2015 and 2023 were reviewed. Demographic information, details of primary diseases necessitating LT, transplantation techniques, and clinical findings associated with PTDH were evaluated. RESULTS: There were seven patients with PTDH. Median age at transplantation was 69 (range: 9-200) months. Five patients received a left lateral sector, one patient had a right lobe, and one had a left lobe graft. Time between LT and PTDH was 9 (2-123) months. One patient who was diagnosed in the postoperative 10th year was asymptomatic. Respiratory distress and abdominal pain were the main symptoms among all. All patients underwent laparotomy, and primary repair was performed in six patients, and one patient required mesh repair because of a large defect. Small intestine herniated in most cases. There were two complicated cases with perforation of the stomach and colonic volvulus. There is no recurrence or long-term complications for the median 60 (20-119) month follow-up period. CONCLUSION: PTDH is a rare but serious complication. Majority of symptomatic cases present within the first postoperative year, whereas some late-presenting cases may not be symptomatic. Inadvertent injury to the inferior phrenic vasculatures due to excessive use of cauterization for control of hemostasis may be a plausible explanation in those cases.

Evaluation of surgical strategies and long-term outcomes in pediatric hepatocellular carcinoma.

PURPOSE: Hepatocellular carcinoma (HCC), the second most common pediatric malignant liver tumor after hepatoblastoma, represents 1% of all pediatric tumors. METHODS: A retrospective study was conducted on children with HCC treated at our center from March 2002 to October 2022, excluding those with inadequate follow-up or records. Demographic data, initial complaints, alpha-fetoprotein (AFP) values, underlying disease, size and histopathological features of the masses, chemotherapy, and long-term outcomes were analyzed. RESULTS: Fifteen patients (8 boys, 7 girls) with a mean age of 11.4 ± 4.1 years (0.8-16.4 years) were analyzed. The majority presented with abdominal pain, with a median AFP of 3.9 ng/mL. Hepatitis B cirrhosis in one patient (6.6%) and metabolic disease (tyrosinemia type 1) in two patients (13.3%) were the underlying diseases. Histopathological diagnoses were fibrolamellar HCC (n:8; 53.3%), HCC (n:6; 40%). Four of the 15 patients underwent liver transplantation, and 9 underwent surgical resection. Due to late diagnosis, two patients were considered inoperable (13.3%). The survival rate for the four patients who underwent liver transplantation was found to be 75%. CONCLUSION: Surgical treatment of various variants of HCC can be safely performed in experienced centers with a multidisciplinary approach, and outcomes are better than in adults.

Transanal endorectal or transabdominal pull-through for Hirschsprung's disease; which is better? A systematic review and meta-analysis.

AIM: Hesitations concerning the long-term results of transanal endorectal pull-through (TEPT) due to prolonged anal stretching and resultant stricture and continence problems has been started to be questioned. This meta-analysis intended to compare long-term results between TEPT and transabdominal (TAB) pull-through techniques in the surgical management of Hirschsprung's disease. METHODS: All publications between the years 1998-2021 in the PubMed, Medline, Google Scholar, Cochrane databases were reviewed. Retrospective and prospective comparative studies for TEPT, TAB as well as Laparoscopic-assisted TEPT (LTEPT) were included. Data included age at operation, postoperative constipation, enterocolitis, incontinence, stricture, and soiling rates. RESULTS: Eighteen publications met the inclusion criteria for TAB and TEPT, and six for TEPT and LTEPT. Patients who underwent TEPT had significantly younger operation age than patients with TAB (SMD - 1.02, 95%Cl - 1.85 to - 0.18, p: 0.0168). Postoperative constipation (OR 0.39, 95% Cl 0.25-0.61 p < 0.0001) and enterocolitis (OR 0.65, 95% Cl 0.46-0.90, p: 0.0108) rates were significantly lower in TEPT groups. Postoperative incontinence (OR 1.06, 95% Cl 0.56-2.01, p: 0.8468), stricture (OR 1.97, 95% Cl 0.81-4.80, p: 0.1352) and soiling rates were similar between the two groups. Furthermore, when TEPT and LTEPT results were compared, incidence of incontinence (OR 7.01, 95% Cl 0.75-65.33, p: 0.0871), constipation (OR 1.95, 95% Cl 0.70-5.37, p: 0.199), enterocolitis (OR 3.16, 95% Cl 0.34-29.55 p: 0.3137), stricture (OR 1.33, 95% Cl 0.29-6.15, p: 0.7188) and soiling (OR 1.57, 95% Cl 0.57-4.31, p: 0.3778) were similar for both techniques. DISCUSSION: TEPT is superior to TAB in terms of constipation and enterocolitis. Contrary to concerns, postoperative incontinence rates are not statistically different. However, further publications about long-term LTEPT results are necessary for more reliable conclusions.

Long-term surgical outcomes in pediatric ovarian neoplasms: 20-year single-center experience.

PURPOSE: The management of pediatric ovarian neoplasms (ON) is based on finding a balance between adequate surgical treatment and future reproductive capacity. We aimed to evaluate long-term results of patients who underwent surgery for ON. METHODS: A retrospective cohort study design was used. Medical records of patients with ON were reviewed. They were invited to participate in a telephone-based survey assessing complaints, menstrual status, and post-surgical recurrence. RESULTS: Eighty-five patients were operated for ON between 1995 and 2015. Median age at surgery was 14.7 years. 62.4% of patients had ovary-sparing surgery (OSS). Median tumor size in oophorectomy group was significantly larger than OSS group (p = 0.029). Median length of follow-up was 5.1 years. Recurrent/metachronous disease was not significantly different between OSS and oophorectomy groups (p = 1.000). In OSS group, irregular menses (p = 0.004) and painful menses (p = 0.002) were significantly higher than oophorectomy group. CONCLUSION: The main goal of treatment in pediatric ON is to find the right balance between adequate and appropriate tumor resection and maximal effort for fertility preservation. Our results showed no difference between oophorectomy and OSS in the terms of recurrence. Although irregular and painful menses were found to be significantly higher in the OSS group, longer follow-up and prospective studies are needed to clarify this issue.

Diffusion tensor imaging in anorectal malformations: a pilot study for the evaluation of lumbosacral plexus.

INTRODUCTION: Neurogenic bladder with anorectal malformations (ARM) is a well-known yet understudied topic. Diffusion tensor imaging (DTI) is a special usage of MRI that can evaluate peripheric nerves. The aim of this study is to evaluate the lumbosacral plexuses of patients with ARM using DTI. PATIENTS AND METHODS: Patients with ARM willing to participate were included. Patient files were reviewed, a questionnaire was made, and DTI was performed. Fractional anisotropy (FA) and apparent diffusion coefficient (ADC) were computed for the right and left lumbosacral plexuses. RESULTS: There were 18 patients and 12 controls. Groups were similar in terms of sex (p = 0.232) and age (p = 0.853). There was a significant difference only for ADC of the left plexus. There was visible asymmetry in tractographies and DTI parameters of two patients with severely deformed pelvises (image 1) but also in another patient with a normal sacrum. In addition, despite asymmetry, FA and ADC were similar to controls also in these patients. CONCLUSION: This is the first study presenting quantitative data about the lumbosacral plexus in ARM. We think the most interesting finding of this study was observing the normal values even in the patients with severely malformed sacrum which is yet to be validated with further studies.

General complications after surgery for anorectal malformations.

The introduction of posterior sagittal anorectoplasty (PSARP) by deVries and Peña in the early 80s has impacted to the treatment of patients with anorectal malformations (ARM). It gained great recognition worldwide in a very short time, and since then, surgeons dealing with the treatment of this complex malformation could achieve tremendous progress in contemporary management of this anomaly. Despite the growing experience and body of information globally, the treatment of ARMs continues to be a challenge to the pediatric surgeons due to the nature and the variability of the anomaly, and short- and long-term problems continue to exist even after nearly 40 years of the PSARP era. Today, knowing more about it, pediatric surgeons are committed to do more for their ARM patients to have them as physically and socially healthy individuals.

Intracellular localization of beta-catenin expression plays a possible prognostic role on the outcome of hepatoblastoma patients.

PURPOSE: Wnt/Beta-catenin pathway plays an essential role in liver development and regeneration. Abnormal activation in this pathway leads to development of hepatoblastoma (HB). Although its importance has invoked attention, its prognostic role is debatable. We aimed to evaluate the significance of intracellular localization of beta-catenin (BC) expression in the outcome of hepatoblastoma patients. METHODS: Medical records of HB patients between 2004 and 2018 were reviewed. Patients were grouped according to intracellular localization of BC expression by immunohistochemistry as being cytoplasmic or nuclear. Demographics, radiological images, PRETEXT classifications, vascular involvement, risk groups, chemotherapy responses, and survival rates were analyzed and compared between groups. RESULTS: There were 41 patients. Thirteen patients were excluded for unavailability of records in four, negative/unclear BC expressions in seven. Cytoplasmic expression of BC was observed in 17 patients whereas 13 patients displayed nuclear expression. Demographics were similar in both groups. Cytoplasmic BC expression was associated with poor chemotherapy response (p = 0.001) and increased vascular involvement (p = 0.0162) requiring more extensive surgeries (p = 0.039). CONCLUSION: Although the numbers are limited in our series, the intracellular localization of BC expression has been found to be a promising determining factor for hepatoblastoma prognosis. With larger patient series, more reliable results can be achieved.

Laparoscopic Treatment of Median Arcuate Ligament Syndrome: A Rare Cause of Chronic Severe Abdominal Pain.

Median arcuate ligament syndrome is a rare disorder characterized by chronic postprandial abdominal pain and weight loss caused by compression on celiac artery. A 17-year-old girl with chronic severe abdominal pain and weight loss was referred to our clinic. Other causes of chronic abdominal pain were investigated and excluded. The compression on celiac artery was detected on Doppler ultrasound and diagnosis was confirmed by computed tomography angiography. The patient underwent laparoscopic release of median arcuate ligament. There were no intraoperative complications; however, partial pain response was observed postoperatively that necessitated para-spinal ganglion blockage. The patient is symptom-free in 1-year follow-up period.

Acquired right diaphragmatic hernia following pediatric living donor orthotopic liver transplantation.

ADH following OLT is a rare entity. Herein, we report a case of Alagille syndrome who developed ADH secondary to OLT, and possible etiological causes are discussed in light of the literature.

Propranolol as the first-line therapy for infantile hemangiomas: preliminary results of two centers.

AIM: Despite a mostly self-limiting course, infantile hemangiomas can cause severe functional and/or cosmetic problems. The aim of this study was to determine the efficiency of propranolol treatment on infantile hemangiomas. METHODS: Sixty-seven infantile hemangioma patients were included in propranolol protocol in two institutions from 2009 to 2011. Participants included 36 boys and 31 girls. An associate protocol with radiology and pediatric cardiology was constructed for appropriate patient selection. Patients received a dose of 2 mg/kg/day, and all were admitted for the first 24 hours of therapy. RESULTS: Sixty-seven patients were included in the study. Mean age at the initiation of therapy was 7 months (1 to 24 months), and eleven patients were older than 12 months of age when propranolol was started. All patients showed improvement with varying responses. No side effects were detected during the treatment. CONCLUSION: Previously defined treatments for hemangiomas were efficient, yet had a limited usage because of side effects. Propranolol, with a high efficacy (not as total involution but stabilization and regression) and feasibility deserves to be the first line therapy for infantile hemangiomas even after the proliferation phase.

The Role of Surgery in Antenatal Ovarian Torsion: Retrospective Evaluation of 28 Cases and Review of the Literature.

STUDY OBJECTIVE: Antenatal ovarian torsion (AOT) is rare and requires differentiating from other congenital cystic masses of the abdomen and pelvis in neonates. In this study, it was aimed to evaluate the prenatal characteristics and postnatal outcomes of AOT. DESIGN, SETTING, PARTICIPANTS, INTERVENTIONS, AND MAIN OUTCOME MEASURES: Hospital records of patients (n = 28) with diagnosis of AOT between 2004 and 2020 were reviewed and their prenatal characteristics, postnatal examination, imaging, operative, and histopathological findings were evaluated. RESULTS: There were 28 patients during the study period. In most of the patients (25/28; 89.3%) AOTs were detected prenatally. All were term babies with a mean birth weight of 3010 ± 466.6 g. Mean maternal age was 25.75 ± 3.65 years. Prenatal history was event-free in all and none had additional anomalies. Physical examination revealed mobile intra-abdominal cystic lesions in 16 (57.1%) patients. AOTs mimicked other pathologies as intestinal duplication cyst or mesenteric cyst (n = 7), complex ovarian cyst (n = 3), mature cystic teratoma (n = 3), simple renal cyst (n = 1), and ectopic kidney (n = 1) in 15 (53.6%) patients in postnatal ultrasonography. Elective laparoscopic surgery was performed in 26 (92.8%) patients. The other 2 patients required emergency open surgery because of acute symptoms. Ovaries were autoamputated in 17 (60.7%) patients. Histopathological examination revealed necrosis and dystrophic calcification in all specimens. There was neoplastic involvement in 2 patients (serous cystadenoma and gonadoblastoma). No complication occurred in the early follow-up period (mean: 73.9 ± 46.8 months). CONCLUSION: AOTs can be detected easily during the antenatal period. Neoplastic involvement with AOTs is rare but possible. Although AOTs might mimic other cystic pathologies, it should be one of the first diagnoses to be considered, in the presence of a palpable intra-abdominal mass and complex cystic lesion in infant girls. It can be efficiently and safely managed using minimally invasive techniques.

A rare cause of refractory ascites in a child: familial Mediterranean fever.

Familial Mediterranean fever (FMF) is hereditary episodic febrile syndrome characterized by acute attacks of fever and serosal inflammation, generally lasting 1-3 days and resolves spontaneously. Apart from abdominal pain, patients may present with variety of abdominal manifestations such as acute peritonitis, mechanical intestinal obstruction, diarrhea, bowel infarction, amyloidosis and small amounts of peritoneal fluid during the acute attacks. A 6-year-old boy was admitted with massive ascites. After extensive laboratory investigations, no causative agent could be identified. On subsequent days, he developed fever and skin eruptions. Acute-phase reactants were increased. A second tomography revealed cystic fluid collection near the anterior side of spleen that invades the stomach. An exploratory was performed and histopathological examination of the all resected specimens revealed mix inflammatory cell infiltrate associated with severe myofibroblast proliferation suggesting chronic inflammatory process on the mesenteric region. A diagnosis of FMF was suspected based on the clinical, laboratory and histopathological findings, and a trial of colchicine therapy initiated. Ascites and other serosal inflammations improved within 1 week without any recurrence during the next 12-month period on colchicine treatment. Atypical presentations of FMF have been increasingly reported. Pediatricians should keep FMF in mind in the differential diagnosis of massive ascites especially in regions where hereditary inflammatory disease are common.

Infections developing in patients undergoing liver transplantation: Recipients of living donors may be more prone to bacterial/fungal infections.

BACKGROUND/AIMS: Despite surgical advances in liver transplantation and effective prophylactic strategies, posttransplant infections are the most important cause of morbidity and mortality. Diagnosis and management of infections because of developing immunosuppression is difficult and adversely affects mortality. This study aimed to review bacterial and fungal infections in patients after liver transplantation and to reveal the resistance rates. MATERIALS AND METHODS: A total of 107 patients who underwent liver transplantation between January 2017 and February 2018 were evaluated retrospectively with regard to demographic characteristics, causes of transplantation, conditions that may lead to infection, postoperative infections, pathogens, and resistance patterns. RESULTS: Of the 107 patients who underwent liver transplantation, 48 (44.8%) had an infection. Bacterial infections were detected in 41% of the patients, and fungal infections were found in 13%. When we compared living and cadaveric transplants in terms of infection development, these rates were found to be 53% and 33%, respectively (p=0.034). No statistically significant results could be obtained when evaluating conditions such as sex, presence of underlying primary disease, Model for End-Stage Liver Disease MELD score, diabetes status, total parenteral nutrition, and risk factors for infection. CONCLUSION: After liver transplantation, infections are often seen in the first month of the postoperative period. Knowing the most common pathogens and resistance states in this process reduces infection-related deaths by providing appropriate treatment regimens at the right time.

Excision of the atrial Wilms` tumor thrombus without sternotomy, atriotomy and cardiovascular By-pass.

Tekin A, Yagmur I, Ergün O, Ayik MF, Atay Y, Ulman I, Avanoglu A. Excision of the atrial Wilms` tumor thrombus without sternotomy, atriotomy and cardiovascular By-pass. Turk J Pediatr 2019; 61: 436-439. The treatment of atrial-extention Wilms` tumor thrombus is surgical excision after chemotherapy. Atriotomy with cardiovascular by-pass is the one of the most common method for this procedure. Herein, we aimed to present a case of Wilms` tumor with a tumor thrombus extending into the right atrium totally excised with retrohepatic cavatomy. A 3.5 year-old girl was admitted with the symptom of dysuria. The examinations revealed a mass consistent with Wilms` tumor in the middle and lower poles of the left kidney. Doppler ultrasound and Echocardiographic examinations showed a tumor thrombus extending into the right atrium and some pulmonary nodules which were interpreted to be metastasis. Wilms` tumor was histopathologically diagnosed by an open biopsy. After three courses of chemotherapy imaging studies revealed that the atrial axtention of the tumor thrombus persisted. The tumor thrombus was found to be fibrotic on the magnetic resonance imaging scan of the patient. Therefore, nephroureterectomy along with the excision of the tumor thrombus from the inferior vena cava was done with intraoperative continuous trans-esophageal echocardiography (TEE). The suprarenal and retrohepatic vena cava were exposed by dissecting and ligating all short hepatic veins and completely mobilizing the right lobe of the liver. The thrombus was dissected out via Vertical cavatomy at the retrohepatic level. TEE confirmed complete removal of the thrombus from the atrium; Vena cava was then repaired. There was no need for a blood transfusion, or cardiovascular by-pass (CPB) during the operation. Total exposure of the retrohepatic and subdiaphragmatic vena cava using transplantation techniques is an effective method for the excision of a tumor thrombus without sternotomy, atriotomy and CPB, avoiding possible intra- and postoperative complications in selected cases of Wilms` tumor with intraatrial thrombus extension. The case emphasises the importance of multidisciplinary communication and collaboration.

A rare complication of central catheter in an infant with intestinal failure.

OBJECTIVE: To report the successful percutaneous transcatheter removal of a snapped intracardiac fragment of the central vein catheter in an infant. CLINICAL PRESENTATION AND INTERVENTION: A 3-month-old infant with short bowel syndrome who required long-term parenteral nutrition via portacath central catheter was hospitalized. Two months after the insertion of the second catheter, the distal tip of the catheter snapped and became tangled in the heart. The catheter fragment was removed by a percutaneous femoral vein approach using a 10-mm diameter snare-loop catheter (Amplatz). The procedure was performed under fluoroscopy; the fragment was removed after being released into the right ventricle by pulling the proximal tip with a pigtail catheter. No complications were observed and the patient was transported back to the intensive unit in stable condition. CONCLUSION: Central catheter-related complications may cause difficulties in patients with short bowel syndrome prior to intestinal transplantation. The percutaneous retrieval of the fragmented catheter using a snare-loop catheter is a safe and reliable technique and may be used instead of surgery especially in small infants.

A simplified cell culture model for research on intestinal inflammation

Background/aim: The aim of this study was to combine some easy and economical defined methods and constitute a comprehensive cell culture model to use in the bowel diseases characterized by inflammation. Materials and methods: Induction of inflammation was performed using lipopolysaccharide (LPS) or a cytokine mixture (TNF-α: 10 ng/mL; IFN-γ: 100 ng/mL; IL-1ß: 1 ng/mL). IEC-6 cells were grown to confluence and serum-starved, wounds were constituted, and progress of cell migration into the wounds was photographed at 0, 2, 4, 6, 8, 10, 12, and 24 h in the presence or absence of an inflammatory environment. Cells were then grown and multiple scratches were performed to replicate the conditions of migration assay. Nitric oxide synthase-2 (iNOS) and cyclooxygenase-2 (COX-2) protein expressions were assessed. Results: Cells covered 88% of the initial wound at 24 h in the control group, 54% in the LPS group, and 35% in the cytokine mixture group. LPS and the cytokine mixture were also found to independently increase iNOS and COX-2 expressions. Conclusion: Our study, being inexpensive and practical, describes a model that integrates some methods to constitute a basic model for bowel diseases characterized by inflammation. It can be integrated as a preliminary experiment for etiopathogenesis and drug research studies.

The Role of Familial Mediterranean Fever Gene Mutation in Treatment of Infantile Colitis With Resistant Perianal Fistula.

Symptoms of infantile inflammatory bowel disease (I-IBD) can be life-threatening and associated with poor prognosis. The presence of Mediterranean fever (MEFV) gene mutations play an important role in treatment of I-IBD. In this article, we describe a case of I-IBD with a resistant fistula, in which remission occurred following colchicine therapy. The patient was a six-month-girl with complaints of bloody diarrhea and a perianal abscess of three months duration. Laboratory tests revealed elevated inflammatory parameters, hypoalbuminemia, and anemia. Results of repeated viral, bacterial and parasitic analyses were negative. Endoscopic and histopathological examinations confirmed a diagnosis of I-IBD. Although diarrhea episodes decreased following intensive conventional treatment with immunosuppressive therapy and anti-tumor necrosis factor, the perianal abscess and fistula did not resolve. Molecular genetic analysis to identify causes of infantile disease revealed the MEFV gene mutation. Thus, colchicine was added to the treatment regimen. Following treatment with colchicine, defecation returned to normal, and the fistula resolved. The MEFV gene mutation should be investigated in children with infantile colitis and resistant fistulas, particularly in Mediterranean countries. In patients with infantile colitis who have the MEFV gene mutation, colchicine treatment may be an alternative to intensive immunosuppressive therapy.

Retrospective Multivariate Analysis of Data from Children with Suspected Appendicitis: A New Tool for Diagnosis.

BACKGROUND: Decision-making for management may sometimes be difficult in acute appendicitis (AA). Various diagnostic scoring systems exist, but their sensitivity and specificity rates are far from ideal. In this study, the determination of the predictors and the effect of radiological data and developing a new scoring system were aimed. METHODS: Medical records of patients who were hospitalized for AA between February 2012 and October 2016 were retrospectively reviewed. All data were compared between patients with and without appendicitis. The multivariate analysis was performed to define significant variables and to examine the sensitivity and specificity of each group of predictors including radiological data. A new scoring system (NSS) was formed and was compared with two existing scoring systems: pediatric appendicitis score (PAS) and Alvarado scoring system (ASS) by using reclassification method. RESULTS: Negative appendectomy rate was 11.3%. Statistical analysis identified 21 independently significant variables. The heel drop test had the highest odds ratio. Sensitivity and specificity rates of clinical predictors were 84.6% and 94.8%, respectively. Radiological predictors increased the sensitivity rate to 86.9%. Sensitivity and specificity rates for PAS, ASS, and NSS were 86.8% and 83.9%, 84.7% and 81.6%, and 96.8% and 95.6%, respectively. The "re-assessed negative appendectomy rate" was 6.2% and false positive results were remarkably more common in patients with duration of symptoms less than 24 hours. CONCLUSION: Radiological data improves the accuracy of diagnosis. Containing detailed clinical and radiological data, NSS performs superiorly to PAS and ASS, regarding sensitivity and specificity without any age limitation. The efficiency of NSS may be enhanced by determining different predictors for different phases of the inflammatory process.

Abernethy Malformation Type 2 and Biliary Atresia Coexistence: A Rare Cause of Infantile Liver Transplant.

INTRODUCTION: Abernethy malformation is a very rare condition in which mesenteric venous blood is drained into systemic circulation by an extra hepatic portosystemic shunt. Here we present a case of a female in infantile period who is a liver transplant candidate with biliary atresia and ventricular septal defect (VSD) accompanying Abernethy malformation type 2. CASE REPORT: The patient who underwent Kasai operation at postnatal day 35 was identified as a liver transplant candidate in the postnatal month 6 due to growth retardation in the infantile period, insufficient weight gain and liver failure (portal hypertension and massive gastrointestinal bleeding). CONCLUSION: Abernethy malformation is divided into two groups as type 1 and type 2; type 2 shunts, which are less common, but more common in males, are not accompanied by other congenital anomalies. Due to the female gender, having biliary atresia and VSD, the development of liver failure at an early stage despite undergoing Kasai operation at the appropriate time, our case differs from the literature. In conclusion, this case is presented in order to indicate the proper and effective use of imaging methods in neonatal cholestasis cases.How to cite this article: Ergon EY, Ermis N, Colak R, Polat B, Ozdemir S, Yildiz M, Kulali F, Ecevit C, Ergun O, Calkavur S.
