    Abstract 1122‐000190: Persistent DWI Signal for 18 Months in Ischemic Stroke Patient with Carotid Web

    Introduction: Diagnostic tools for acute ischemic infarcts include the use of DWI sequence on MRI to identify acute infarcts is especially useful since lesions can become hyperintense on this sequence very rapidly (Albers 1998). Over the next 15 days, DWI hyperintensity slowly decreases back to isointense. In some patients, however, there is persistent DWI hyperintensity past 1 month. There are theories that these persistent areas exhibit delayed onset infarct, prolonged ischemia, or perhaps different repair processes (Rivers, et al 2006). To this day, all DWI signals have been known to resolve within a few months even for persistent hyperintensities (Rivers, et al 2006). Carotid webs are a rare form of fibromuscular dysplasia that protrudes from the intimal tissues of carotid arteries. They are shelf‐like projections that grow into the lumen and disrupt normal blood flow (Zhang, et al 2018). These outgrowths are theorized to lead to ischemic strokes due to flow stasis and subsequent embolization of clots that form (Zhang, et al 2018). There is no consensus on the best management of carotid webs, and secondary prevention of recurrent strokes range from medical management to carotid stenting. Methods: This is a case report, and information for the patient was gathered through review of medical records on the EMR. Results: We present a case of ischemic stroke in the right basal ganglia/corona radiata, who presented with left sided weakness. The patient was found to have prediabetes, HTN, and HLD. However, she had recurrence of her symptoms over the next 18 months (figure 1). Repeat MRIs showed persistent DWI hyperintensity that slowly decreased in size and signal intensity over this period but in the same area as the initial infarct. The rest of the work up was only significant for a carotid web in the right internal carotid artery identified on conventional angiography. Ultimately she was managed with medical therapy including aspirin, statin, and antihypertensives. Conclusions: It is unclear whether the carotid web is associated with persistent DWI for such an extended time frame. There is very little research that explores the pathophysiology of ischemic strokes from carotid webs. In addition, there is even less information about the physiology of an evolving infarct that shows persistent DWI signals for such an extended time frame. Further studies that look into carotid webs may help us understand the best long term management in such patients. Future studies that explore the physiology of ischemic strokes that show such persistent DWI signals may elucidate and perhaps expand upon current management options and possibly identify new areas for intervention

    Strike Three Yer Out!? : Examining the Constitutional Limits on the Use of Prior Uncounseled DWI Convictions to Impose Mandatory Prison Sentences on Repeat DWI Offenders

    No full text
    This Comment examines the constitutional implications of using prior uncounseled DWI convictions to incarcerate repeat DWI offenders. The Comment reviews the Supreme Court decisions that established the right to court-appointed counsel for the indigent accused and examines the federal constitutional limitations on the collateral use of prior uncounseled DWI convictions. It also critically evaluates state court decisions involving the collateral use of prior uncounseled DWI convictions. The author concludes that, because an uncounseled conviction is inherently unreliable, it should not be used to mandatorily incarcerate a DWI repeat offender

    The prevention of young driver's DWI (driving while intoxicated) and RWDI (riding with a driver under influence) in Europe: A social-sequential model

    No full text
    Inspired by the 'critical incident technique' of McKnight et al. (1995) who analyzed 12,000 drivers' decisions leading to (or not to) DWI, and indentified the influence of social, motivational, and economic factors, the author has developed a social-sequential model of young drivers' DWI and RWDI prevention

    Matrix is one among math subjects which are considered hard. Matrix is considered hard mainly because there are so many calculations needed to be done. Because of the same reason, finding faults in the calculations is also hard, which makes the learning process that mainly consists of exercises harder. To overcome that, a matrix calculator software which can show the calculation steps was developed. The development produced prototype model which has five main features, which are elementary row operation helper, basic matrix operation calculator, matrix form calculator, matrix determinant calculator using Laplace expansion, and a solver for linear equations using Cramer’s rule. The application had been tested with black box testing for its functionality which shows that every feature was working properly. However, this application has not been tested for its effectivity, so it is still considered a prototype.Matriks adalah salah satu materi matematika yang dianggap sulit. Materi matriks dianggap sulit utamanya karena banyaknya perhitungan yang harus dilakukan. Karena alasan itu pula, mencari kesalahan perhitungan juga sulit, sehingga membuat proses pembelajaran yang sebagian besar adalah pengerjaan latihan soal semakin sulit. Untuk mengatasi itu, dikembangkanlah suatu aplikasi penghitung matriks yang dapat menampilkan langkah-langkah perhitungannya. Pengembangan aplikasi ini menggunakan model prototipe yang memiliki lima fitur utama, yaitu pembantu operasi baris elementer, penghitung operasi matriks, penghitung bentuk-bentuk matriks, penghitung determinan matriks dengan ekspansi Laplace, dan penyelesaian persamaan linear dalam bentuk matriks dengan aturan Cramer. Pengujian aplikasi dilakukan dengan metode black box testing untuk menguji fungsionalitasnya yang menunjukkan bahwa setiap fitur aplikasi berfungsi dengan baik. Akan tetapi, aplikasi ini belum diuji efektivitasnya, sehingga masih dianggap prototipe

    An integrated system approach to characterise a drinking water infrastructure system

    No full text
    The object of this article is the drinking water infrastructure (DWI), a critical societal infrastructure. To make effective decisions it is important to characterise and understand the complexity of DWI systems. DWI systems can be seen as a system of systems, consisting of the social-ecological system and the social-technical system. The social-ecological system determines the location and seize of the water resources, while the social-technical system is about the technical infrastructure. The two systems with different characteristics must align to work effective together in the DWI system. The tension between different lifecycles of the assets and dynamic changes in both systems, the time of change, is important to take into account. The SoPhyTech infra framework was developed based on the two systems and time of change. The advantages of applying the SoPhyTech infra framework is studied in a case comparing two very different DWI systems: Indonesia (Semarang) and the Netherlands (Vitens). The SoPhyTech infra framework was shown to be effective for characterising a DWI system with different interacting lifecycles in different systems and it is expected that it also can be used to characterise other infrastructure systems.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Sanitary Engineerin

    The Use of Serial Non EPI DWI MRI Scans to Determine the Growth of Cholesteatoma

    No full text
    Introduction  It is an established practice to use non-EPI DWI MRI scans to detect the presence of cholesteatoma post operatively.  In the present era of Covid-19 where routine surgery to remove cholesteatoma has been suspended resulting in potentially unprecedented demands on the service, a review of serial MRI scans performed over a 7 year period was undertaken to determine the rate of growth of cholesteatoma. Materials and Methods  A retrospective longitudinal study identified 24 middle ear cholesteatomas in 17 patients with serial non-EPI DWI MRI scans (having excluded those having surgical intervention between scans) for a median period of 33 months (range of 6-91 months).  Cholesteatomas were measured by the first author and by the consultant radiologist. Results   Of 24 cholesteatomas, 1 resolved completely, 5 reduced, 6 stayed the same size, 4 grew slowly and 8 grew significantly. Conclusion   Non-EPI DWI MRI scans to determine cholesteatoma growth in asymptomatic ears is useful in triaging patients in the Covid-19 era
