In a consecutive series of 26 previously operated patients diagnosed with cerebral glioma, magnetic resonance spectroscopy (MRS), 2-((18)F) fluoro-2-deoxy-D-glucose positron emission tomography (FDG-PET), and perfusion MRI (MRP), were performed at follow-up to distinguish recurrence from radiation necrosis, and to identify tumour upgrading. Discrepancy between techniques was observed in 9 cases...
abstract background: abnormal uterine bleeding (aub) is one of the most common complains in women of any age seeking gynecologic health care and needs early diagnosis and proper management due to its impacts on the quality of life. this study was conducted to investigate the cut-off value of endometrial thickness (et) by trans-vaginal ultra-sonography (tvus) and evaluate its accuracy in the dia...
Objective. To evaluate the performance of ultrasound in pediatric appendicitis and the integration of US with the pediatric appendicitis score (PAS) and C-reactive protein (CRP). Method. An institution-based, retrospective study of children who underwent abdominal US for suspected appendicitis between 2012 and 2015 at a tertiary pediatric surgery center. US results were dichotomized, with a non...
Background and Objective: This study was undertaken to assess the ability of standard urinalysis (UA) and hemocytometer white blood cell (WBC) counts for the diagnosis of urinary tract infection (UTI) in patients with urinary symptoms. Materials and Methods: A total of 600 patients with symptoms of urina...
OBJECTIVE To assess the effectiveness of the Veress needle puncture in the left hypochondrium and the accuracy of the tests described for the intraperitoneal correct positioning of the tip of the Veress needle in an unselected population. METHODS Ninetyone patients consecutively scheduled for Videolaparoscopy had the abdominal wall punctured in the left hypochondrium. There were no exclusion ...
OBJECTIVE To analyze the contribution of multiparametric MRI and PCA3 assay, predecision of initial biopsy in PSA level between 3-10 ng/mL patients with normal digital rectal examination(DRE). MATERIALS AND METHODS PSA level 3-10 ng/mL, patients, with normal DRE results and no previous prostate biopsy history, were included in this study. Each patient underwent multiparametric MRI one week be...
background: according to age, history and physical examination findings, there are different diagnoses including anatomic lesions for abnormal uterine bleeding (aub). in these conditions, hysteroscopy can be performed as a diagnostic and therapeutic procedure. objective: the aim of this study was defining the diagnostic value of hysteroscopy in evaluating uterine cavity in patients with aub com...
BACKGROUND Combined testing of high-sensitivity cardiac troponin T (hs-cTnT) and copeptin at presentation provides a very high-although still imperfect-negative predictive value (NPV) for the early rule-out of acute myocardial infarction (AMI). We hypothesized that a second copeptin measurement at 1 h might further increase the NPV. METHODS In a prospective diagnostic multicenter study, we me...
BACKGROUND High-risk human papillomavirus (hrHPV) testing has higher sensitivity but lower specificity than cytology for cervical (pre)-cancerous lesions. Therefore, triage of hrHPV-positive women is needed in cervical cancer screening. METHODS A cohort of 1,100 hrHPV-positive women, from a population-based screening trial (POBASCAM: n = 44,938; 29-61 years), was used to evaluate 10 triage st...
Background: Iron deficiency (ID) is the most common micronutrient deficiency in the world. If left untreated, ID will lead to iron deficiency anemia (IDA) and other irreversible consequences. The American Academy of Pediatrics recommended reticulocyte hemoglobin content (Ret-He) as an alternative laboratory examination to screen and detect ID. We aimed to compare Ret-He with other laboratory pa...
