Radiologic Predictors of Visual Outcome in Myelin Oligodendrocyte Glycoprotein-Related Optic Neuritis.

Purpose: This study aimed to determine whether magnetic resonance imaging (MRI) biomarkers are associated with visual prognosis in myelin oligodendrocyte protein (MOG)-associated optic neuritis (ON).

Design: Cross-sectional analysis.

Participants: Patients meeting 2023 international diagnostic criteria for MOG antibody-associated disease who were seen for first episodes of MOG-associated ON at 3 tertiary neuro-ophthalmology practices between January 2017 and July 2023 were enrolled.

Assessment of Reversibility of Transverse Venous Sinus Stenosis in Patients With Papilledema.

Background: Bilateral transverse venous sinus stenosis (TVSS) or stenosis of a dominant venous sinus has been found to be very sensitive radiological findings in patients with intracranial hypertension (IH), yet there is still an ongoing debate whether they constitute reversible or permanent phenomena. Thus, the purpose of this study was to investigate the reversibility of TVSS in patients with IH, including conservatively treated patients with signs of IH as defined by the presence of papilledema.

Methods: This was a retrospective chart review of all patients diagnosed with IH between 2016 and 2022, assessed from 2 tertiary university-affiliated neuro-ophthalmology practices.

The presence of pachymeningeal hyperintensity on non-contrast flair imaging in patients with spontaneous intracranial hypotension.

Purpose: Traditionally, in the work-up of patients for spontaneous intracranial hypotension, T1 post-contrast imaging is performed in order to assess for pachymeningeal enhancement. The aim of this study is to assess whether pachymeningeal hyperintensity can be identified on a non-contrast FLAIR sequence in these patients as a surrogate sign for pachymeningeal enhancement.

Methods: The patient cohort was identified from a prospectively maintained database of patients with a clinical diagnosis of intracranial hypotension.

Standardised aspiration first approach reduces materials used and cost of thrombectomy procedure in anterior circulation large vessel occlusion stoke.

Purpose: The aim of this study is to compare the volume of equipment and equipment costs in a cohort of consecutive patients with anterior circulation large vessel occlusion treated with a standardised aspiration first approach to those treated with a stent retriever first approach.

Methods: The equipment used in each case was recorded from a prospectively maintained equipment log. We then compared the volume of equipment used in each group.

Is CT thorax, abdomen and pelvis a useful test in patients with weight loss?

Introduction: Unintentional weight loss is an important clinical problem. The role of CT is not firmly established in the workup of these patients. The aim of this study is to determine the diagnostic yield of CT Thorax, Abdomen and Pelvis (CT TAP) in patients with unexplained weight loss and to determine whether clinical or laboratory variables are associated with positive CT findings.

Derivation of a Clinical Score for Prediction of Recurrence Following Evacuation of Chronic Subdural Hematoma: A Retrospective Cohort Study at a National Referral Centre.

Background: Chronic subdural hematoma (cSDH) is a common pathology, and recurrence is a common complication, which may be predicted by certain patient and radiologic factors. Empiric radiologic surveillance has been shown to convey no benefit.

Methods: A retrospective review of a prospectively collated database was performed.

Improving endovascular access to the target vessel for thrombus aspiration -Use of the wedge device to overcome anatomic hurdles.

Background And Purpose: Aspiration is a successful technique used in thrombectomy for acute stroke. It is contingent upon the appropriate position of the aspiration catheter, so that it is in contact with the thrombus. However, navigating the craniocervical vasculature is challenging is some patients.

Role of routine post-operative CT brain following evacuation of extradural haematoma in children: a single-centre experience.

Purpose: Extradural haematoma (EDH) is a serious neurosurgical emergency in children, which confers significant morbidity and mortality rates. The objective of this study was to retrospectively evaluate the role of post-operative imaging in children with EDH who were managed surgically in a national paediatric neurosurgical unit over a 9-year period (January 2008 to December 2016).

Methods: A retrospective case review of paediatric patients who underwent surgical evacuation of extradural haematoma between January 2008 and December 2016 was performed.

Medical device patents-a review of contemporary global trends with an Irish comparison.

Introduction: Trends in medical technology patents provide an objective comparison of research and development between countries and over time. An analysis of these trends can benchmark innovation within Ireland in a worldwide context. By identifying and examining leading countries, domestic educational, infrastructural, regulatory and fiscal planning may be optimised.

Breast screening in symptomatic women over 35 years of age: improvements in service efficiency.

Introduction: The rationalization of cancer services in Ireland saw all women with symptomatic breast problems referred to one of the eight regional cancer centers. A pilot triaging system was introduced in St Vincent's University Hospital to streamline these services. Women over 35 years who do not meet urgent referral criteria are referred for a mammogram prior to a clinic appointment ("image first").
