Paediatric computed tomography diagnostic reference levels in Africa: A systematic review

open access: yesJournal of Medical Radiation Sciences, Volume 72, Issue 1, Page 139-147, March 2025.
Improvements in computed tomography (CT) technology have increased its applications in medical imaging. Variations in the paediatric DRLs indicate that harmonisation and standardisation of paediatric CT protocols are essential for the optimisation of paediatric doses. Abstract Introduction Improvements in computed tomography (CT) technology in terms of

Overview of Diagnostic Ultrasound Safety

open access: yesJournal of Ultrasound in Medicine, EarlyView.
Ultrasound is widely regarded as a safe imaging modality; however, emerging ultrasound‐based techniques—such as shear wave elastography and contrast‐enhanced ultrasound—operate with varying acoustic output parameters that may approach or exceed traditional diagnostic limits. As these technologies are increasingly integrated into human research studies,

Lack of evidence for central sensitization in idiopathic, non-traumatic neck pain : a systematic review [PDF]

open access: yes, 2015
Background: Chronic neck pain is a common problem with a poorly understood pathophysiology. Often no underlying structural pathology can be found and radiological imaging findings are more related to age than to a patient's symptoms.

Impact of Environmental and Seasonal Factors on Spontaneous Pneumomediastinum With and Without Pneumorrhachis

open access: yesThe Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Spontaneous pneumomediastinum (SPM) with pneumorrhachis is rare but generally benign and self‐limiting. However, the impact of environmental and seasonal factors on SPM remains unclear. This study investigated their association with SPM onset and clinical outcomes.

Transoral Robotic‐Assisted Removal of a Submucosal Pyriform Sinus Foreign Body

open access: yesThe Laryngoscope, EarlyView.
Submucosal foreign bodies of the medial pyriform sinus represent a challenge given limited visualization and difficult retraction with endoscopic approaches, and risk of injury to the recurrent laryngeal nerve with open approaches. We present a novel case utilizing the Da Vinci SP system for removal of an embedded fishbone from the medial pyriform ...

Ergonomics of In‐Office Nasolaryngoscopy: Comparison Between Conventional and Pistol Grip Techniques

open access: yesThe Laryngoscope, EarlyView.
ABSTRACT Objectives In‐office nasolaryngoscopy in otolaryngology is a short but frequently performed procedure that can lead to substantial ergonomic risk. This study seeks to compare the ergonomic difference between pistol and conventional grip techniques during in‐office nasolaryngoscopy.
