324). Patients with other neurological disorders had even lower concentrations (21.4±10.6ng/ml) than patients with BPPV (p<0.005), patients with other vestibular disorders (p<0.005) and all patients with vestibular disorders (24.9 ± 10.1ng/ml, p<0.005). Our analysis does not support the theory of a specific relationship between serum 25(OH)D concentration and the occurrence of BPPV or other vestibular disorders.Our analysis does not support the theory of a specific relationship between serum 25(OH)D concentration and the occurrence of BPPV or other vestibular disorders.We report the case of a previously healthy 16-year-old male who developed myopericarditis following the second dose of his Pfizer-BioNTech COVID-19 vaccine, with no other identified triggers. Adolescents and young adults experiencing chest pain after COVD-19 vaccination should seek emergent medical care, and emergency providers should have a low threshold to consider and evaluate for myopericarditis. CldU More data are needed to better understand the potential association between COVID-19 vaccines and myopericarditis. If a true causal link is identified, the risk must also be viewed in context with the millions of patients who have been safely vaccinated and the known morbidity and mortality from COVID-19 infection. As we see widespread vaccine rollout, it is important that all potential adverse reactions are reported as we continue to monitor for more rare but potentially serious side effects not identified in vaccination trials. Dolichoarteriopathies of the extracranial part of the internal carotid artery (ICA) are associated with cerebrovascular events, yet information on their prevalence and risk factors remains limited. The aim of the present study therefore was to study the prevalence and risk factors of dolichoarteriopathies in a sample of patients with cerebrovascular symptoms from the Plaque At RISK (PARISK) study. In a random sample of 100 patients from the PARISK study, multidetector computed tomography angiography (MDCTA) was performed as part of clinical workup. On MDCTA, we evaluated the extracranial trajectory of the ICA by measuring the length (in millimeters), the tortuosity index (TI; defined as the ICA length divided by the shortest possible distance from bifurcation to skull base), and dolichoarteriopathy type (tortuosity, coiling or kinking). Next, we investigated the association between cardiovascular risk factors and these measurements using linear and logistic regression analyses. The mean (standard deviaty of these abnormalities. Recipient site preparation is a crucial step in non-cultured epidermal cell suspension (NCES) as it facilitates proper uptake of the grafted melanocytes. To compare the repigmentation rate of recipient sites prepared with manual dermabrasion (MD) versus electrofulguration-assisted dermabrasion (EF) in patients undergoing NCES for treatment of stable vitiligo. This was a prospective randomized study including 26 patients of stable vitiligo (VIDA 0 or -1), each having two patches of size greater than 3×3cm located symmetrically or at the same site or a single patch of 6×6cm or larger. After randomization of patches in the given patient, MD and EF were performed on recipient areas followed by NCES. The patients were followed up at 4weekly intervals up to 24weeks and assessed for extent of repigmentation and adverse effects if any. Greater than 75% repigmentation was observed in 69.3% of the patches prepared by MD as compared to 73.1% patches prepared by EF at the end of 24weeks (p=0.791). The mean improvement in target VASI was 64.0% in the MD group as compared to 68.8% in the EF group (p=0.21). Patches prepared by EF achieved successful repigmentation earlier as compared to patches prepared by MD (9.4weeks vs 11.4weeks, p=0.12). Both MD and EF have comparable outcomes with respect to all parameters.Both MD and EF have comparable outcomes with respect to all parameters. Emergency departments (ED) interface with large numbers of patients that are often missed by conventional HIV testing approaches. ED-based HIV self-testing (HIVST) is an innovative engagement approach which has potential for testing gains among populations that have failed to be reached. This systematic review and meta-analysis evaluated acceptability and uptake of HIVST, as compared to standard provider-delivered testing approaches, among patients seeking care in ED settings. Six electronic databases were systematically searched (Dates January 1990-May 2021). Reports with data on HIVST acceptability and/or testing uptake in ED settings were included. Two reviewers identified eligible records (κ=0.84); quality was assessed using formalized criteria. Acceptability and testing uptake metrics were summarized, and pooled estimates were calculated using random-effects models with assessments of heterogeneity. Of 5773 records identified, seven met inclusion criteria. The cumulative sample was 1942 subjects, dthe limitations of the reports, additional research is needed to better inform the evidence base. This study investigated whether long-term benzodiazepine use is associated with increased 90-day mortality among patients with sepsis. A retrospective population-based cohort study based on health records obtained from the National Health Insurance Service database in South Korea was conducted. All adult patients (≥18years) admitted to the hospital with a primary diagnosis of sepsis or septic shock during 2010-2018 were included in the study. Sepsis and septic shock were diagnosed based on the International Classification of Diseases (10th revision A40, A41 and R65.2). Benzodiazepine users were defined as individuals who were prescribed regular benzodiazepine continuously for over 6months before admission. A total of 251837 patients with sepsis were included in this study, 16686 of which (6.6%) were benzodiazepine users, and 235151 (93.4%) were non-users. After propensity score (PS) matching, 33370 patients (16685 in both groups) were ultimately included. Moreover, following PS matching, the 90-day morteases, such as depression or anxiety disorder.
