    The purpose of this study was to examine the relationship between school principals’ power styles and teacher alienation. The participants were a total of 582 teachers working in elementary, middle and high schools located in Karabuk, Turkey. This study used a correlational survey research design. The data were gathered through the Teacher Alienation Scale and Power Type Scale. The arithmetic mean, the Pearson product-moment correlation coefficient and regression analysis were used for data analysis. The results showed that school principals’ reward power and school principals’ personality power were negatively correlated with teacher alienation. School principals’ coercive power and legitimate power were positively related with teacher alienation. It was found that school principals’ reward power predicted teacher alienation negatively and significantly. Also, school principals’ coercive power predicted teacher alienation positively and significantly

    BACKGROUND: Abdominal aortic aneurysm formation is among the arterial complications of Behcet's disease. Weakness and fragility of aortic walls leads to the development of arterial complications like pseudoaneurysms. CASE PRESENTATION: A case of huge saccular abdominal aortic aneurysm in a young Behcet patient who was successfully treated with endovascular stent graft placement is reported, diagnostic and interventional procedures are discussed, and mid-term follow-up results are presented. CONCLUSIONS: Endovascular treatment of abdominal aortic aneurysm complications of young Behcet patients who are not suitable for open surgery and need intervention could be an alternative treatment modality even without performing preprocedural angiography

    PURPOSEBiliary complications develop at a higher rate in living donor liver transplantation (LDLT) compared with cadaveric liver transplantation. Almost all studies about biliary complications after LDLT were made with the right lobe. The aim of this study was to determine the frequency of biliary complications developing after adult left lobe LDLT and to evaluate the efficacy of the algorithm followed in diagnosis and treatment, particularly percutaneous radiological treatment.METHODSA total of 2185 LDLT operations performed in our center between May 2009 and December 2019 were retrospectively reviewed and patients receiving left lobe LDLT were analyzed regarding biliary complications and treatments. Biliary complications were treated via percutaneous drainage under ultrasound (US) guidance, endoscopic retrograde cholangiopancreatography (ERCP), and percutaneous transhepatic cholangiography (PTC)/ percutaneous transhepatic biliary drainage (PTBD). Patient demographics, ERCP procedures before percutaneous treatment, and percutaneous treatment indications were analyzed.RESULTSA total of 69 adult patients received left lobe LDLT. Biliary complications requiring endoscopic and/or percutaneous treatment developed in 28 patients (40%). Of these patients, 4 had bile leakage (14%), 20 had anastomosis stricture (72%), and 4 had both leakage and anastomosis stricture (14%). External drainage treatment under ultrasound guidance was sufficient for 2 of 4 patients with bile leakage, and these cases were accepted as minor bile leakage (7%). Overall, 26 patients underwent ERCP; of these, 8 were referred for PTC/PTBD because the guidewire and/or balloon-stent could not pass the anastomosis stricture (n=7) and common bile duct cannulation could not be obtained because of duodenal diverticulum (n=1). Diagnostic PTC was performed in 10 patients, 8 were referred after inadequate/failed ERCP procedure and two were referred directly without ERCP. Anastomosis stricture was found in 7 patients and anastomosis stricture and bile leakage in 3. In 7 patients determined to have stricture, balloon dilatation was applied and then biliary drainage was performed. In 3 patients who had leakage and anastomosis stricture, balloon dilatation was applied for stricture; after dilatation, an IEBD catheter was placed through the leakage region in 2 patients, while a covered metallic stent passing through the leakage region was placed in one patient.CONCLUSIONGenerally, ERCP is the first preferred method in biliary complications of LDLT; however, in cases where a response cannot be obtained by endoscopic treatment or require complex and/or aggressive treatment, percutaneous radiological treatment should be the treatment of choice before surgery in left lobe LDLT

    PURPOSEActive bleeding due to abdominal trauma is an important cause of mortality in childhood. The aim of this study is to demonstrate the advantages of early percutaneous transcatheter arterial embolization (PTAE) procedures in children with intra-abdominal hemorrhage due to blunt trauma.METHODSChildren with blunt abdominal trauma were retrospectively included. Two groups were identified for inclusion: patients with early embolization (EE group, n=10) and patients with late embolization (LE group, n=11). Both groups were investigated retrospectively and statistically analyzed with regard to lengths of stay in the intensive care unit and in the hospital, first enteral feeding after trauma, blood transfusion requirements, and cost.RESULTSThe duration of stay in the intensive care unit was greater in the LE group than in the EE group (4 days vs. 2 days, respectively). The duration of hospital stay was greater in the LE group than in the EE group (14 days vs. 6 days, respectively). Blood transfusion requirements (15 cc/kg of RBC packs) were greater in the LE group than in the EE group (3 vs. 1, respectively). The total hospital cost was higher in the LE group than in the EE group (4502 USD vs. 1371.5 USD, respectively). The time before starting enteral feeding after first admission was higher in the LE group than in the EE group (4 days vs. 1 day, respectively).CONCLUSIONEarly embolization with PTAE results in shorter intensive care and hospitalization stays, earlier enteral feeding, and lower hospital costs for pediatric patients with intra-abdominal hemorrhage due to blunt trauma

    Effects of testicular microlithiasis on Doppler parameters: report of three cases

    Get PDF
    BACKGROUND: Testicular microlithiasis is a rare, usually asymptomatic, non-progressive disease of the testes associated with various genetic anomalies, infertility and testicular tumors. According to our literature search, there is no specific data about Doppler findings in this disease. CASE PRESENTATION: Doppler findings of three cases of testicular microlithiasis during last two years in our institution are presented. CONCLUSIONS: Although our hypothesis was to find increased Doppler parameters due to intratesticular arterial compression, our findings suggest that there are no Doppler findings specific to testicular microlithiasis

    Mevcut çalışma, doğal steroid saponin kaynağı olarak yeme ilave edilen Yucca schidigera tozunun yumurta tavuklarında verim, yumurta kalitesi ve kolesterol içeriği üzerine etkisini belirlemek amacıyla yürütülmüştür. Denemede hayvan materyali olarak kullanılan 28 hafta yaşlı 60 Beyaz Hyline yumurtacı tavuklar, deneme başında benzer canlı ağırlık ve verim düzeyine sahip ve herbirinde 15 hayvanın bulunduğu 4 yemleme grubuna ayrılmışlardır. Denemede temel yem materyali olarak 1. dönem kafes tavuğu yumurta yemi kullanılmış ve deneme yemleri, temel yem materyaline Ö, 30,60 ve 120 ppm düzeylerinde yucca tozu katkısı ile oluşturulmuştur. Denmede elde edilen bulgulara göre rasyona Yucca schidigera tozu katkısının, özellikle 60 veya 120 ppm düzeyinde, istatistik! olarak önemli (P>0.05) düzeyde olmasa da yumurta verimini artırdığı, yemden yararlanma düzeyini iyileştirdiği, yem tüketimi, canlı ağırlık kazancı ve kırık-çaîlak yumurta oranını azalttığı, yumurta akı, şansı ve kabuk ağırlıklarını, şekil endeksini ve kabuk kalınlığını ise değiştirmediği gözlenmiştir. Öte yandan, rasyona yucca tozu katkısı yumurta kolesterol içeriğini önemli (P0.05) on egg shell, white and yolk weights, shell thickness, shape index. However, it was observed that yucca supplementation significantly (<0.05) reduced yolk cholesterol content in a dose related manner. The reduction in yolk cholesterol content was also found to be time dependent (<0.01), as the longer periods the birds received Yucca schidigera powder, the lower the egg cholesterol content they exhibited

    BACKGROUND: The aim of this study was to evaluate frequency and severity of kidney involvement with some clinical, ultrasonography and color Doppler measurements in patients with Behçet disease. MATERIAL AND METHODS: This study was including 32 patients with Behçet disease and 32 healthy sex and age-matched control subjects. Patients were divided into two groups as period of disease 0-6 years and 7 years and above to evaluate effect of duration of disease. We evaluated some biochemical tests in both blood and urine related to renal functions, blood pressure values. Gray scale and color Doppler findings were noted. RESULTS: Renal artery volume flow in patients with a duration of 7 years or above was significantly decreased compared to control group (p<0.05). However, gray scale ultrasound and color Doppler measurements reveal there was not statistically significant change compared to control group. There was no biochemical abnormalities in any patient. Four patients had elevated blood pressure but mean blood pressure values were not statistically different compared to volunteers. CONCLUSIONS: Renal involvement ratios varies in different studies but not common. End stage renal failure can be seen very rare. Furthermore, vasculitic changes can lead renal artery narrowness and can result to decrease in renal blood flow. It has a potential to activate renin angiotensin aldosterone cascade to elevate blood pressure. We must be aware about blood pressure of patients with Behçet disease, especially with long term follow up
