Right VI palsy revealing nasopharyngeal cancer (UCNT)

VI paralysis is a frequent and classic pathology in the clinical consultation of ophthalmology. The main difficulty is the diagnostic process (for the etiology). In young adults, be aware of the possibility of a tumor with the correlation of rapid imaging. UCNT is frequent in Morocco, its neurological symptoms are misleading because we do not always think of examining the nasopharynx properly in the event of damage to the cranial pairs. Improving the prognosis for this cancer requires early diagnosis.

Exploiting spatio-spectral aberrations for rapid synchrotron infrared imaging

The Infrared Microspectroscopy Beamline at the Australian Synchrotron is equipped with a Fourier transform infrared (FTIR) spectrometer, which is coupled with an infrared (IR) microscope and a choice of two detectors: a single-point narrow-band mercury cadmium telluride (MCT) detector and a 64 × 64 multi-pixel focal plane array (FPA) imaging detector. A scanning-based point-by-point mapping method is commonly used with a tightly focused synchrotron IR beam at the sample plane, using an MCT detector and a matching 36× IR reflecting objective and condenser (NA = 0.5), which is time consuming. In this study, the beam size at the sample plane was increased using a 15× objective and the spatio-spectral aberrations were investigated. A correlation-based semi-synthetic computational optical approach was applied to assess the possibilities of exploiting the aberrations to perform rapid imaging rather than a mapping approach.

97 What Are the Main Delays to Surgery After A Patient Presents with An Acute Type A Aortic Dissection?

Introduction Acute-aortic-dissection (AAD) represents a serious cardiovascular emergency, with an associated mortality of 1-2% per hour after symptom onset. It is known that the relative infrequency of AAD and plausible differentials can negatively impact on a timely diagnosis. Female sex, absence of typical features and high-risk examination findings (hypotension/pulse deficits) shown to delay diagnosis. In UK, services for AAD are centralised, working on established volume/outcome relationships. However, this has the potential to introduce delays in rapidly diagnosing patients without on-site specialist support and in the logistics of transferring patients across large distances. This study aims to report on time taken for patients to receive surgery after first presentation at local hospital and identify points that contribute to maximal delay. Method Retrospective analysis of all operated type-A-aortic-dissections at our hospital in 2019. Hospital database used to identify patients, and local/referring hospital documentation reviewed to establish times. Results Mean time from A&E presentation to surgery is 8-hours-and-30 minutes (4:16–13:43). Largest contributor to delay is time from A&E admission to CT scan. Conclusions Our findings suggest greatest impact on improving times from presentation to surgery is to increase awareness of AAD in regional, non-specialist hospitals and to encourage rapid imaging.

Development of 1,8-Naphthalimide dyes for a rapid imaging of subcellular compartments in plants

Here, we report the installation of 1,8-naphthalimide dyes in live cell imaging of plants. We developed a series of 1,8-naphthalimide-based probes that illuminate different subcellular compartments by altering their spectroscopic...
