    PurposeA positive whirlpool sign (WS) is defined as the presence of a spiral-like pattern when the spermatic cord is assessed during ultrasonography (US), using standard, high-resolution ultrasonography (HRUS) and/or color Doppler sonography (CDS), in the presence of testicular torsion. The objective of this review was to assess the validity and accuracy of this sign by performing a comprehensive systematic literature review and meta-analysis.MethodsIn accordance with the Preferred ...

    Background: There is a high prevalence of paediatric emergency cases in less developed countries. However, prolonged hospital stay at emergency units may further overstretch the facilities.

    Objective: To assess the patterns of presentations, services offered and predictors of a prolonged stay at the Children Emergency Room of a tertiary hospital in Southern Nigeria.

    Methods: This prospective cross-sectional, study was conducted at the University of Calabar Teaching Hospital, Nigeria from ...

    BACKGROUND: Intestinal volvulus is a potentially life-threatening condition that occurs when loops of bowel twist around its supporting mesentery and associated vasculature. Clinicians often rely on various radiological investigations for prompt diagnosis to avoid complications such as bowel infarction. This review assesses the clinical reliability of the ultrasonographic whirlpool sign (WS) in the diagnosis of intestinal volvulus.

    METHODS: In adherence with the PRISMA (Preferred ...

    Introduction: Puberty is an essential physiologic process that is characterized by the appearance of secondary sexual features. Secular changes in puberty occur from one generation to another and need to be documented. The assessment of pubertal stages in a child is only useful if recent and reliable reference data from the same population is available for comparison. The study aimed to profile clinical normative sexual maturity characteristics for children in Calabar, South-South ...

    Introduction: Procedural sedation and analgesia allows the clinician to safely and efficiently administer sedation, analgesia, anxiolysis and sometimes amnesia to facilitate the performance of various procedures in the emergency centre. The aim of this study is to determine current sedation practices, common indications and major obstacles in selected emergency centres across Southern Gauteng, South Africa, with a view to improving future standards and practices.

    Methods: This was a ...

    Presentation to the emergency department with renal colic has been reported as between 6.7 and 27.9 per 1000 emergency department visits. Clinicians rely on various radiological investigations for the prompt and accurate diagnosis of urolithiasis. This review assesses the validity of the colour Doppler ultrasonographic twinkling artefact (TA) sign as a diagnostic tool for the presence of urolithiasis. A systematic search of the Cochrane Database of Systematic Reviews, Embase, PubMed, ...
