Background: The purpose of the present study was to compare the serum levels of IL6 and CA125 in women with and without endometriosis. They were also compared in mild, moderate and severe cases. Methods: In this case-control study, CA125 and IL6 levels in 76 women with laparoscopic proven endometriosis were compared with 76 women without evidence of endometriosis. Sensitivity, specificity, p...
BACKGROUND The diagnosis of typhoid fever is confirmed by culture of Salmonella enterica serotype Typhi (S. typhi). However, a more rapid, simpler, and cheaper diagnostic method would be very useful especially in developing countries. The Widal test is widely used in Africa but little information exists about its reliability. METHODS We assessed the performance of the Widal tube agglutination...
BACKGROUND To demonstrate the diagnostic accuracy of an integrated approach of blind trans-bronchial needle aspiration (TBNA) and (99m)Tc-2-methoxy-isobutyl-isonitrile single photon emission computed tomography ((99m)Tc-MIBI-SPECT) in diagnosing mediastinal lymph adenopathy. METHODS Sixty one consecutive patients with mediastinal lymph adenopathy undergoing both TBNA and (99m)Tc-MIBI-SPECT we...
Background and purpose: Determining the severity and site of rotator cuff tear (RCT) is very important for choosing a treatment method. In this study, the diagnostic value of indirect magnetic resonance arthrography (I-MRA) and magnetic resonance imaging (MRI) were compared. Materials and methods: This cross-sectional study was performed in 36 patients attending an orthopedic clinic in 2020. P...
OBJECTIVES To determine the optimal threshold of blood and urine neutrophil gelatinase-associated lipocalin (NGAL) to predict moderate to severe acute kidney injury (AKI) and persistent moderate to severe AKI lasting at least 48 consecutive hours, as defined by an adjudication panel. METHODS A multicentre prospective observational study enrolled intensive care unit (ICU) patients and recorded...
Introduction FINDRISC (Finnish Diabetes Risk Score) is a risk assessment tool widely used for the prediction of the development of type 2 diabetes (T2DM), combining a questionnaire with simple anthropometric measurements to identify patients at risk of developing diabetes, with increasing score (0-26) signifying increased risk. A cut off score of 9 has previously been proposed (with drug-treate...
Aim of this study was to evaluate the performance of saline hydrosonography (HSGM) (also known as saline infusion sonography (SIS)) against transvaginal ultrasound scan (TVS) and hysteroscopy in the diagnosis of uterine cavity lesions. Diagnostic hysteroscopy with biopsy is considered as the "gold standard" to diagnose intrauterine abnormalities. The introduction of HSGM has improved the diagno...
OBJECTIVE To validate a revised version of the paediatric South African Triage Scale (SATS) against admission as a reference standard and compare the sensitivity of triage using: (i) clinical discriminators; (ii) an age-appropriate physiological composite score; and (iii) a combination of both. METHODS A prospective cohort study was undertaken validating the revised paediatric SATS against ou...
PURPOSE Large-scale observational studies based on existing medical databases may have an important role in studies of long-term effects of different treatments in prostate cancer patients if the coding of the treatment is valid. We therefore estimated the positive predictive value (PPV) and negative predictive value (NPV) of hospital codes for gonadotropin-releasing hormone (GnRH) agonist trea...
PURPOSE We investigated the effectiveness of tele-mentored ultrasonography between emergency medicine (EM) residents and remote experts in diagnosing acute appendicitis. METHODS This prospective observational study was performed in an academic emergency department. Beginning in June 2014, the EM residents performed the initial ultrasonography for suspected pediatric acute appendicitis; then, ...
