Magnetic resonance imaging safety in Asia-Oceania: call for action.

Magnetic Resonance Imaging (MRI) safety is a critical concern in the Asia-Oceania region, as it is elsewhere in the world, due to the unique and complex MRI environment that demands attention. This call-for-action outlines ten critical steps to enhance MRI safety and promote a culture of responsibility and accountability in the Asia-Oceania region. Key focus areas include strengthening education and expertise, improving quality assurance, fostering collaboration, increasing public awareness, and establishing national safety boards.

Implementation of Public Funded Genome Sequencing in Evaluation of Fetal Structural Anomalies.

With the advancements in prenatal diagnostics, genome sequencing is now incorporated into clinical use to maximize the diagnostic yield following uninformative conventional tests (karyotype and chromosomal microarray analysis). Hong Kong started publicly funded prenatal genomic sequencing as a sequential test in the investigation of fetal structural anomalies in April 2021. The objective of the study was to evaluate the clinical performance and usefulness of this new service over one year.

Embolisation of an aneurysmal high-flow renal arteriovenous fistula in a paediatric patient: simultaneous arterial and venous approach.

Background: A large aneurysmal renal arteriovenous fistula (AVF) can cause hypokalaemic hypertension due to activation of renin-aldosterone system due to steal effect from renal parenchyma. In comparison to nephrectomy, endovascular embolisation of renal AVF is minimally invasive and can be nephron sparing, thus preserving renal function. However, such embolisation is technically challenging and can be associated with high risk of embolic migration.

Vertical gaze palsy and intraoral numbness in a patient with neuro-psychiatric systemic lupus erythematosus: A case report and literature review.

We report, to the best of our knowledge, the first case of neuropsychiatric systemic lupus erythematosus with clinical presentation of bilateral upward gaze palsy and intraoral numbness. Magnetic resonance imaging of the brain was able to identify the pathogenic lesion at the left side of midbrain, involving the vertical gaze center and sensory pathways for innervating the buccal and hard palate mucosa. A course of aggressive immunosuppressive treatment resulted in prompt resolution of gaze palsy and the midbrain lesion.

Simple clinical tests may predict severe oropharyngeal dysphagia in Parkinson's disease.

Objective: To determine if simple screening tests can predict severe oropharyngeal dysphagia in subjects with Parkinson's disease.

Methodology: Forty-five subjects (26 females) of average age 75 (range: 65-94) who were classified as Modified Hoehn and Yahr stages 2 to 5 were enrolled. The presence of oropharyngeal dysphagia was assessed by a symptom questionnaire, 50 ml water swallowing test and videofluroscopic swallowing study.
