CT sinography provides limited additional information about the extent of draining tracts compared to pre- and post-IV contrast CT images and did not increase the number of foreign bodies identified.

Infarction of the medulla has been associated with prolongation of the QTc, severe arrhythmia, and sudden cardiac death, yet the precise anatomical substrate remains uncertain. We sought to determine the possible anatomical structures relating to QTc-prolongation in patients with acute medullary infarction. We included 12 subjects with acute ischemic medullary infarction on brain MRI, who presented within 4.5h from the last known well time, with a 90-day follow-up. For an unbiased lesion analysis, medullary infarcts were manually outlined on diffusion weighted MRI and co-registered with an anatomical atlas. Nine out of 12 had QTc-prolongation. Qualitative and semi-quantitative comparisons were made between infarct location and QTc-prolongation. Among patients with QTc-prolongation, the greatest degree of congruence of the infarct location was over the dorsal vagal nucleus (DVN, 8 out of 9). There was a significant correlation between the number of sections showing infarction of the DVN and presence of QTc-prolongation (r=.582, p=.047). Among patients without QTc-prolongation, the maximum lesion overlap included the medial aspect of the gigantocelluar reticular nucleus of the reticular formation. We found that the DVN is a key anatomical substrate related to QTc-prolongation. Further studies with more patients and high-resolution, volumetric MRI are needed to confirm our findings.

Our approach draws inspiration from African ethics and from the characterization of the Covid-19 crisis as a syndemic, a convergence of biosocial forces that interact with one another to produce and exacerbate clinical disease and prognosis. The first section elaborates the twin ideas of syndemic and solidarity. The second section argues that these ideas lend support to global health alliances to distribute vaccines beyond national borders. The third section introduces ethical criteria to guide global distribution, emphasizing priority to low- and middle-income countries, which have the least ability to obtain vaccines on their own. It also justifies giving priority to people at high risk of infection and high risk of severe disease and death. A renewed National Cervical Screening Program (NCSP) was introduced in Australia in December 2017. Under the renewed NCSP, there are limited data to guide the management of discordant colposcopy and biopsy results after a liquid-based cytology (LBC) finding of 'possible high-grade squamous intraepithelial lesion' (pHSIL). This study aims to determine the proportion of women referred with pHSIL who are found to have HSIL, identify influencing factors of women most at risk, and examine the role that cytopathology review plays in management decisions. Two-hundred and thirty-two women presenting to a tertiary women's hospital in Australia with pHSIL since December 2017 were identified. Women with HSIL following colposcopy directed biopsy were referred for treatment. When HSIL was not identified, these patients were referred for multidisciplinary clinicopathological review. Pathological outcomes and treatment recommendations are included. The primary outcome of the study was histological confirmation of HSIL. Pri
