BACKGROUND Percutaneous lag screw fixation is an alternative treatment for non-displaced or minimally displaced posterior column fractures. This study aims to explore new fluoroscopic views of the acetabulum for safe percutaneous insertion of posterior column lag screws. METHODS Axial computed tomography (CT) scans were taken of sixteen embalmed adult cadavers. The axial CT images at the leve...
PURPOSE The purpose of this study was to determine the potentialof cancer testis (CT) antigens as vaccines for non-Hodgkin's lymphomas (NHLs). EXPERIMENTAL DESIGN Ninety-three specimens of NHLs were analyzed for their composite expression of eight CT genes (MAGE-3, MAGE-4, CT-7, HOM-MEL-40/SSX-2, SSX-1, SSX-4, HOM-TES-14/SCP-1, and HOM-TES-85). Thirty-nine of these specimens were also analyze...
A multicenter clinical study was conducted to evaluate the performance characteristics of the Abbott RealTime CT/NG assay, a multiplex real-time PCR assay, for simultaneous detection of Chlamydia trachomatis and Neisseria gonorrhoeae. The specimens were collected from a total of 3,832 male and female subjects at 16 geographically diverse sites. Specimens included male and female urine samples, ...
The aim of the present study was to compare the porosity characteristics of AH Plus Jet(tm) syringe-mix and the conventional hand-mixed AH Plus root canal sealers by three-dimensional quantitative high-resolution micro-computed tomography (micro-CT). Seven test specimens were prepared from each tested sealer by a single operator following the manufacturer's instructions and poured into pre-lubr...
BACKGROUND Invasive fungal diseases (IFD) are an important cause of morbidity and mortality in immunocompromised patients, and early diagnosis and management are a challenge. We evaluated the clinical utility of computed tomography (CT)-guided percutaneous lung biopsies in diagnosing IFD. METHODS Between 2003 and 2014, we analyzed 2671 CT-guided lung biopsies, from which 157 were IFD associat...
BACKGROUND The compression of the median nerve (MN) in the carpal tunnel (CT) is one of the most common aetiologies of entrapment neuropathy syndromes in clinical practice. The aim of this study was to investigate the relationship of the palpable bony prominences of the distal forearm (radial styloid process [RSP] and ulnar styloid process [USP]) with MN in the CT, in order to determine a safe-...
OBJECTIVE To study the relationship between the pre and post chemotherapy (CT) serum levels of alkaline phosphatase (AP) and lactate dehydrogenase (LDH), and the percentage of tumor necrosis (TN) found in specimens after the pre surgical CT in patients with osteosarcoma. METHODS Series of cases with retrospective evaluation of patients diagnosed with osteosarcoma. Participants were divided in...
We recently reported an increase in dicentric chromosome (DIC) formation after a single computed tomography (CT) scan (5.78-60.27 mSv: mean 24.24 mSv) and we recommended analysis of 2000 metaphase cells stained with Giemsa and centromere-FISH for dicentric chromosome assay (DCA) in cases of low-dose radiation exposure. In the present study, we analyzed the frequency of chromosome translocations...
conclusion the fdg pet/ct showed a high sensitivity and a high negative predictive value for identifying malignancies in thyroid nodules with indeterminate fnab results. therefore, the fdg pet/ct may be a helpful tool in the clinical management of these nodules. when an fdg positive lesion is detected, further examination is recommended. background thyroid nodules with indeterminate fine-needle...
BACKGROUND Sinus fungus ball, an accumulation of fungal dense concretions, is a common disease in practice, and might cause fatal complications or lead to death once converted into invasive type. Early preoperative diagnosis of this disease can lead to appropriate treatment for patients and prevent multiple surgical procedures. Up to now, the diagnostic criteria of sinus fungus ball have been d...
