Öğe Diagnostic value of diuretic-enhanced excretory MR urography in patients with obstructive uropathy(ELSEVIER IRELAND LTD, 2004) Karabacakoglu, A; Karakose, S; Ince, O; Cobankara, OE; Karalezli, GPurpose: Ultrasonography and conventional intravenous urography are most common methods in diagnosis of obstructive uropathies. The disadvantage of ultrasonography is inability of visualizing middle and lower one thirds of ureter, while intravenous urography is using radiation, also functionally extra loading effect on kidneys. In this study, the diagnostic value of MR urography on obstructive uropathy were investigated. Materials and methods: Forty five patients who were suffered from obstructive uropathy examined by ultrasonography, intravenous urography and diuretic-enhanced excretory MR urography by using MR-contrast-agent. Results: MR urography established accuracy rate of 92.8% for stone diseases which formed the largest group in this study, however, in other causes of obstructive uropathy, MR urography provide 100% correct diagnosis. Conclusion: MR urography provide high quality images for diagnosing and determining causes of urinary obstruction defining position and severity of dilatations as well as showing localization of the pathology. We think that MR urography should be a primary investigation in patients with obstructive uropathy who have contrast agent and X-ray contrindication. (C) 2003 Elsevier Ireland Ltd.

Two hundred knee MRI examinations were analyzed: 56 male right, 44 male left, 42 female right and 58 female left. Measurements of the intercondylar height (ICH), intercondylar width (ICW), medial condylar width (MCW), lateral condylar width (LCW) and epicondylar width (EW) were obtained. The notch shape index (NSI) was also calculated. Statistical analysis for comparisons was done by Students t-test. Correlations between the parameters studied were calculated by Pearson correlation coefficients. Significant bilateral differences were not found (p > 0.05). In all measurements, males showed significantly greater values than females (p < 0.001). No difference was seen in the NSI between males and females (p > 0.05). Conversely a significant association was obtained between age and all parameters. We conclude that the results of this study may be useful for anatomic evaluation of the distal femur region prior to orthopaedic operations.Öğe The role of hyperbaric oxygen in the management of subarachnoid hemorrhage(SPRINGER, 2004) Kocaogullar, Y; Ustun, ME; Avci, E; Karabacakoglu, A; Fossett, DObjective: To determine the role of hyperoxic and hyperbaric therapy following experimental subarachnoid hemorrhage (SAH). Design: Prospective, randomized, controlled animal study. Subjects: Thirty male Wistar rats. Interventions: Thirty rats were assessed for an initial neurologic status as double-blinded by two different neurosurgeons using a neurologic severity score (NSS) and then underwent an initial angiographic examination. Two days later, 0.3 ml of homologous blood was injected into the cisterna magna to produce a SAH-induced cerebral vasospasm. The NSS and angiographic examination were then repeated. The rats having no spasm or a spasm under 50% (n=8) and 50% or over 50% (n=22) were grouped separately, as groups 1 and 2, respectively. The rats having 50% or more spasm were further divided randomly into group 2A and 2B. The rats in groups 1 and 2A (n= 11) underwent a 60-min course of 100% oxygen at the atmospheric pressure 1 atmosphere absolute (ata), and group 2B (n= 11) received 100% oxygen at 3 ata for I h. Neurologic assessment was repeated on the next day and 7 days later. Measurements and main results: The animals having no spasm or less than 50% spasm had a better NSS and outcome when compared with the animals having 50% or more spasm. But the animals with 50% or more spasm which underwent hyperbaric therapy were shown to have a better outcome compared to the animals having hyperoxic therapy. Conclusion: Exposure to hyperbaric oxygen therapy seemed to accelerate the recovery of neurologic deficits secondary to experimental SAH.Öğe Spontaneous rupture of choledochal cyst presenting in childhood(TURKISH J PEDIATRICS, 2005) Kiresi, DA; Karabacakoglu, A; Dilsiz, A; Karakose, SSpontaneous rupture of coledochal cysts is one of the rare complications, and can sometimes be the initial manifestation. It should be considered in the presence of bile-like fluid. A 10-year-old girl had acute onset of abdominal pain, vomiting, and elevated bilirubin, alkaline phosphatase, glutamic oxaloacetic transaminase and glutamic-pyruvic transaminase levels. There was no trauma in her history. In ultrasonography and computed tomography, dilated common bile duct, cystic mass of 10x6 cm, and free intraperitoneal fluid in abdominal cavity were demonstrated. Radiological methods, especially intraoperative cholangiography, should be performed for evaluation. We report a case of spontaneous rupture of the choledochal cyst with clinical and radiological findings.
