Introduction: While it can be difficult to categorize thyroid lesions, employing ultrasound may enable correct diagnosis, classification, and therapy of nodules, particularly papillary carcinoma the thyroid, assist save unneeded biopsy. Objective: Taking histopathology as gold standard, assessing diagnostic precision in identification cancer nodule patients. Study design: Cross sectional study ...

BACKGROUND Hyaluronic acid (HA) serum levels correlate with the histological stages of liver fibrosis in hepatitis C virus (HCV) monoinfected patients, and HA alone has shown very good diagnostic accuracy as a non-invasive assessment of fibrosis and cirrhosis. The aim of this study was to evaluate serum HA levels as a simple non-invasive diagnostic test to predict hepatic fibrosis in HIV/HCV-co...

Advances in medical imaging, together with the development of many new minimally invasive diagnostic and therapeutic techniques, have had a huge impact on the practice of neurosurgery. Image-guided, minimally invasive methods that use microinstruments, lasers, catheters, and endoscopes are achieving results comparable to or better than those obtained with traditional surgical resection. Better ...

Ultrasonography is the main non-invasive technique for screening of ureterocele, but presents some difficulties for its diagnosis. Other supplementary diagnostic methods have the disadvantage of being invasive or using ionizing radiation. Magnetic resonance (MR) has a high sensitivity for diagnosing urinary tract malformations in adults and children. We report one case of ureterocele in a 1-yea...

Background: Obscure gastrointestinal bleedings accounting for 5%-30% of all continue to be a challenge and usually originate from the small bowel. Clinical case: We present case female patient hospitalized with signs bleeding three times within 3 months. could not identify source using standard methods, such as abdominal computed tomography ultrasonography, esophagogastroduodenoscopy, colonosco...

There are no definitive diagnostic tests for early detection, diagnosis and staging of Parkinson’s disease (PD). Available methods have thus far failed to yield high accuracy, are expensive, and can be highly invasive to the patient. The use of serum biomarkers for the diagnosis of early-stage PD has the potential to provide an accurate, inexpensive, and non-invasive alternative to conventional...

The US Centers for Disease Control and Prevention lists Brucella as a potential bioterrorism threat requiring enhanced diagnostic capacity and surveillance (http://emergency.cdc.gov/bioterrorism/). Successful treatment and management of patients after exposure to biological threat agents depends on accurate and timely diagnosis, but many biothreat agents present with similar, vague clinical sig...

Differentiation of wide QRS complex tachycardias on surface electrocardiograms is difficult for physicians and computers due in part to their inability to identify atrial activity, specifically atrioventricular (AV) dissociation. We studied 20 examples ofAV associated rhythms and 17 examples ofAV dissociated ventricular tachycardia. We applied an algorithm consisting of subtraction of a mean be...

Recognition of acute rejection after heart transplantation has been based mainly on invasive methods until now. In this study we analyzed two well-defined surface electrocardiographic recordings by fast Fourier transform (FFT) (Blackman Harris window, 512 points) after low-noise, high-gain amplification (filter setting 0.5 to 300 Hz) each day for 4 weeks after cardiac transplantation in 27 pati...
