ABSTRACT: To evaluate the levels of thrombin-activatable fibrinolysis inhibitor (TAFI) activity and also its relationship with other homeostasis markers in breast cancer patients.
Forty-two female patients with breast cancer and 24 healthy women (controls) were enrolled in the study and fasting blood samples of all cases were drawn from a large antecubital vein for assay of TAFI and other homeostasis tests.
The TAFI levels were 79.5 ± 15.5 and 39.3 ± 12.1 in patients and controls, respectively, and the difference was statistically significant (p < 0.001). In the patient group, the serum fibrinogen level was 504.9 ± 224.8, while in the control group it was 393.9 ± 100.5, and the difference was also statistically significant (p < 0.001).
The data showed that increased levels of TAFI are a contributing factor of thrombotic disorders in breast cancer patients.

ABSTRACT: To compare the success and immediate complication rates of the anatomical landmark method (group 1) and the radiologically (combined real-time ultrasound and fluoroscopy) guided technique (group 2) in the placement of central venous catheters in emergent hemodialysis patients.
The study was performed prospectively in a randomized manner. The success and immediate complication rates of radiologically guided placement of central venous access catheters through the internal jugular vein (n=40) were compared with those of the anatomical landmark method (n=40). The success of placement, the complications, the number of passes required, and whether a single or double-wall puncture occurred were also noted and compared.
The groups were comparable in age and sex. The indication for catheter placement was hemodialysis access in all patients. Catheter placement was successful in all patients in group 2 and unsuccessful in 1 (2.5%) patient in group 1. All catheters functioned adequately and immediately after the placement (0% initial failure rate) in group 2, but 3 catheters (7.5% initial failure rate) were non-functional just after placement in group 1. The total number of needle passes, double venous wall puncture, and complication rate were significantly lower in group 2.
Percutaneous central venous catheterization via the internal jugular vein can be performed by interventional radiologists with better technical success rates and lower immediate complications. In conclusion, central venous catheterization for emergent dialysis should be performed under both real-time ultrasound and fluoroscopic guidance.

ABSTRACT: Methylmalonic acidemia (MMA) is an inborn disorder of amino acid metabolism, often presenting with neurological symptoms. We present the results of magnetic resonance imaging (MRI) and diffusion-weighted imaging (DWI) of the brain in a 16-month-old male patient with classic neurological and laboratory findings for MMA. MRI demonstrated the hyperintensity within globi pallidi both on T2-weighted image and DWI during the acute episode of metabolic acidosis.

ABSTRACT: Lhermitte-Duclos disease (LDD) is a rare cerebellar disorder of uncertain pathogenesis characterized by enlargement of cerebellar folia. Magnetic resonance imaging is the diagnostic modality of choice and usually distinguishes the LDD by its characteristic "striated or laminated pattern" appearance. Various additional abnormalities have been reported in association with LDD. We report a case of LDD coexisting with neurofibromatosis type 1 (NF-1) and non-ossifying fibroma.

ABSTRACT: The aim of this study was to investigate the utility of table-moving contrast-enhanced three-dimensional MR angiography in the evaluation of lower extremity peripheral arterial bypass grafts. Twenty-two lower extremity peripheral arterial grafts (13 autologous saphenous vein, 7 polytetrafluoroethylene and 2 Dacron) in 18 patients were evaluated. Preoperative diagnosis were occlusive arterial segments in 14 cases, 4 aneurysms in 2 cases (3 aneurysms in one case) and traumatic femoral artery injury in 2 cases. 1.5T superconductive magnet was used with torso-phase and whole body coil system on MRI examinations. Lower extremity peripheral arterial grafts were evaluated and anastomosis sites were classified into five groups as normal, insignificant stenosis (< 50%), significant stenosis (> 50%), occlusion and ectatic or aneurysmatic appearance. Contrast-enhanced MR angiography imaging of 66 segments of 22 graft patients were of high quality. No difficulties were confronted in the radiological evaluation of peripheral bypass grafts. Graft stenosis as detected in five grafts. Stenotic segments were at the proximal (n = 4) and distal (n = 3) anastomosis sites. Total occlusion was shown in three grafts. Ectasia or aneurysm was seen in only one graft. In lower extremity peripheral bypass graft patients, table-moving contrast enhanced MR angiography can be used in the evaluation and follow-up of the vascular lesions.

ABSTRACT: Compression of the left main coronary artery by a dilated pulmonary artery can be a life-threatening condition. It can present with angina, symptoms of left ventricular dysfunction, and sudden death. Diagnosis and treatment of this condition is very important. We demonstrate significant compression of the left main coronary artery on coronary angiography and thorax CT examinations.

ABSTRACT: Left atrial and dural calcification in chronic renal failure is very rare. Massive atrial calcification can lead to arrhythmia and diagnosis of this condition is important to take prophylactic measures in dialysis patients. Noninvasive diagnosis of left atrial calcification is also important as it can complicate valvular surgery. We report on a patient with chronic renal failure presenting with arrhythmia in whom left atrial calcification involving interatrial septum is diagnosed by thorax CT examination.

ABSTRACT: We describe a case of an oncocytoma occurring in the adrenal gland, a rare location, and describe US and CT findings of this tumor in our patient. The mass was well marginated but heterogeneous on both CT and US and unfortunately the imaging findings of the tumor are non-specific.

ABSTRACT: The objective of the study was to determine the value of spiral computerized tomography (CT) in detecting urolithiasis in pediatric patients and compare its efficacy with ultrasound (US). Twenty-nine infants aged between 2 to 94 months with clinical presentation suggestive of urolithiasis and a negative or indeterminate plain film were included in the study. Abdominal US and spiral CT were performed in all patients. Presence, size and localization of stones were noted for each patient on both CT and US. The diagnosis of urolithiasis was confirmed by passage of stones spontaneously, extracorporeal shockwave lithotripsy (ESWL), surgery, or clinical follow-up. Presence of stones was confirmed in 23 of 29 patients (79%). Eight patients had single stone and the remaining 15 had multiple stones either in a single localization (single kidney or single ureter) or multiple localizations. Spiral CT detected 57 stones (45 renal and 12 ureteral). US detected 34 stones (59.6%) in 18 (78.2%) patients. US was able to localize 31 stones (68.8%) in 21 kidneys (75%), and 3 stones (25%) in 11 ureters (27.2%). Spiral CT is very effective in the diagnosis of pediatric urolithiasis. Spiral CT is more efficient than US in imaging pediatric patients with symptoms and signs of urolithiasis, when KUB is inconclusive.

ABSTRACT: A case of hepatobiliary cystadenoma with mesenchymal stroma and a case of biliary cystadenocarcinoma are presented. Hepatobiliary cystadenoma and cystadenocarcinoma are rare liver lesions that are difficult to diagnose preoperatively. Regardless of the diagnostic modalities used these two pathologies cannot be differentiated with accuracy. The preoperative diagnosis of biliary cystadenoma and cystadenocarcinoma was suggested due to the radiological detection of vascularity in the septa and the invasion of the thoracoabdominal wall. The surgeon was informed in both of the cases. Pathologic examination confirmed the diagnosis in both of our patients. The radiological features of these pathologies are discussed in detail together with a brief review of the literature.
