STUDY OBJECTIVE To evaluate the accuracy of positron emission tomography (PET) in determining the presence of malignancy in patients presenting with new lung findings, either as an incidental finding or after treatment of a primary carcinoma. DESIGN A retrospective review of the PET database of our hospital from April 29, 1997, to March 20, 1999, identified 196 patients referred for the evalu...

OBJECTIVES To determine the utility of hematuria testing in a large series of patients with suspected renal colic using unenhanced helical computed tomography (CT) as the reference standard. METHODS A retrospective review of the CT reports of all patients who underwent unenhanced helical CT for suspected renal colic at one institution during a 3.5-year period and who also underwent a formal m...

Introduction: Different imaging modalities are used to evaluate salivary gland diseases, including tumors. Ultrasonography (US) is the preferred method on account of its ease of use, affordability, safety profile, and good tolerance among patients. The aim of this study was to evaluate the role of US in differentiating malignant from benign parotid tumors, in the context of previous controversy...

  Abstract   Background: Squamous cell carcinoma (SCC) constitutes the main oral malignancy .   Parallel to better understanding of molecular and genetic patterns of tumor behavior, more precise correlation of tumor markers such as Epidermal Growth Factor (EGF) and Laminin-5 are sought to estimate macroscopic and microscopic tumor status .   Methods: We conducted a cross-sectional study collect...

Background Objective: To evaluate the utility of specific cut-off values for C- reactive protein (CRP) and immature-to-total neutrophil ratio (I/T) as screening tests for meningitis in culture negative early onset sepsis (EOS). Materials and Methods Retrospective chart review of 97 newborns with culture negative sepsis who had lumbar puncture performed as part of the sepsis evaluation in a l...

BACKGROUND AND PURPOSE A screening test is required to improve the diagnosis of poststroke cognitive impairment. The Montreal Cognitive Assessment (MoCA), a newly designed screening test, has been found to be more sensitive than Mini-Mental State Examination (MMSE), but its clinical value has not been established by means of a comprehensive neuropsychological battery. This study was designed to...

BACKGROUND AND PURPOSE Isocitrate dehydrogenase (IDH) has been shown to have both diagnostic and prognostic implications in gliomas. The purpose of this study was to examine whether DWI and DSC-PWI combined with conventional MR imaging could noninvasively predict IDH mutational status in World Health Organization grade II and III astrocytomas. MATERIALS AND METHODS We retrospectively reviewed...

OBJECTIVE To evaluate the utility of N terminal pro brain natriuretic peptide (NT-proBNP) as a diagnostic marker for diastolic dysfunction or failure, systolic dysfunction, and significant valve disorders in patients over 75 years. DESIGN Cohort study. SETTING Outpatient echocardiography service in a district general hospital. PARTICIPANTS 100 consecutive patients. MAIN OUTCOME MEASURES...

Mortality due to cardiovascular complications (CVC) in patients with end stage renal disease (ESRD) is 20 fold higher than in general population. Adiponectin (ADPN) hormone from adipose tissues accumulation in serum is attributed to reduced renal clearance. The aim of this study was to investigate the possible role of ADPN as a predictor of CVC in adult patients with ESRD on hemodialysis (HD), ...

OBJECTIVE To find out the predictive value of the ΣΔST/ΔHR index for restenosis after percutaneous coronary intervention (PCI). METHOD Subjects of this research were patients who participated in a cardiac rehabilitation (CR) program as six to eight weeks of a hospital-based program after receiving PCI to treat acute coronary syndrome (ACS). The patients received coronary angiography (CAG) at ...
