The main reason for endodontic failure is the presence of some species of bacteria inside the root canal system such as Enterococcus (E.) faecalis. Those bacteria are more resistant to disinfection agents, causing a persistent intra-radicular or extra-radicular infection. The current review aims to compile all the current studies concerning Enterococcus faecalis as a dental root canal pathogen that causes endodontic failure. In this systemic review, two databases, PubMed and Google Scholar, were searched using specific inclusion and exclusion criteria. Among 2943 studies, only 11 met the inclusion criteria and were included in the review for further analysis. The 11 studies give prominence to the high distribution of Enterococcus faecalis within the root canal system. These studies investigated different aspects of Enterococcus faecalis, including its prevalence, resistance mechanisms, characteristics, express survival genes, and treatment. The compiled data observed that most of the studies highlight Enterococcus faecalis as the primary pathogen associated with endodontic treatment. It has characteristic proprieties that make it capable of escaping disinfection means. Furthermore, clinical trials are required to examine E. faecalis and may provide valuable information about novel microbial detection methods to decrease the number of E. faecalis within the root canal system.

In this report, we discuss a patient who sustained blunt abdominal trauma leading to the development of an adrenal hemorrhage and his unexpected sequelae of symptoms. Discovery of the source of the patient's symptoms was delayed secondary to multiple comorbidities in the critical care setting and work-up for other sources such as infection and agitation. Hypertensive urgency was confirmed to be of adrenal etiology with measurement of persistently elevated plasma and urine metanephrines during the hospital course. The patients hypertensive urgency was successfully managed with the use of antisympathomimetics including an esmolol drip, clonidine, and eventually tapered dose of metoprolol. Symptoms improved over time, and repeat CT imaging weeks later showed resolution of the hematoma. Review of literature reveals only one other case of adrenal hemorrhage after blunt force trauma resulting in hemorrhagic psuedotumor. To our knowledge, this is the second such case ever presented. This case is discussed along with the presentation, diagnostic work-up, and treatment of a critically ill patient with an adrenal hemorrhage masked as a pseudotumor.

We sought to analyze the magnitude of misinformation that is being spread on Twitter (Twitter, Inc., San Francisco, CA) regarding the coronavirus epidemic.  Materials and methods We conducted a search on Twitter using 14 different trending hashtags and keywords related to the COVID-19 epidemic. We then summarized and assessed individual tweets for misinformation in comparison to verified and peer-reviewed resources. Descriptive statistics were used to compare terms and hashtags, and to identify individual tweets and account characteristics. Results The study included 673 tweets. ABT-199 cell line Most tweets were posted by informal individuals/groups (66%), and 129 (19.2%) belonged to verified Twitter accounts. The majority of included tweets contained serious content (91.2%); 548 tweets (81.4%) included genuine information pertaining to the COVID-1tion and unverifiable content pertaining to the global COVID-19 epidemic are being propagated at an alarming rate on social media. We provide an early quantification of the magnitude of misinformation spread and highlight the importance of early interventions in order to curb this phenomenon that endangers public safety at a time when awareness and appropriate preventive actions are paramount.

While there are several types of sleep apnea, OSA is the most common. Methodology This descriptive online cross-sectional study assessed knowledge, awareness, and attitudes towards OSA over 30 days in a nonrandomized sample of the general population of the Asir region of Saudi Arabia. Subjects were included if they lived in the Asir region and were aged >18 years. Results Of the respondents who participated in the study, 64% were aware of OSA, whereas 36% were not. Most respondents reported that OSA was dangerous, whereas 24% did not know whether OSA was dangerous. Moreover, 81% of respondents reported that they did not know about methods of diagnosing OSA, and 84% did not know about the methods to treat OSA. Conclusions Subjects living in the Asir region of Saudi Arabia showed a low level of awareness of all aspects of OSA. Their lack of sources of knowledge indicates the need for medical staff to improve awareness and knowledge of OSA.

Our intention was to search, analyze and highlight the effects of spinal cord stimulators on end-organ perfusion. We also looked at vascular diseases of atherosclerotic and nonatherosclerotic nature by examining objective evidence of improved circulation, pain control, limb salvage, and quality of life. We paid specific attention to disease processes such as cerebral hypoperfusion, Chronic-Critical Limb Ischemia, Intractable Angina Pectoris (IAP), Raynaud's syndrome and Thromboangiitis Obliterans. We performed a Medline database search for medical literature relevant to Spinal cord stimulators encompassing the years 1950 to 2019. Search terms included "Spinal cord stimulator," plus one of the following search terms vasculopathy, stroke, cerebral blood flow, angina pectoris, diabetic ulcers, chronic critical leg ischemia, thromboangiitis obliterans and peripheral vascular disease. We included both clinical and experimental human studies that investigated the effect of SCS's on end-organ perfusion. We also investigated the pathophysiological mechanism of action of SCS's on the vasculature. We found 497 articles of which 43 more relevant and impactful articles investigating the hemodynamic effects of SCS and its possible mechanism were selected. Animal studies were excluded from the literature review as they provided heterogeneity. In addition to reporting literature supporting the use of stimulators for currently FDA approved uses, we also actively looked for potential future uses. Spinal Cord stimulators showed improvement in cerebral blood flow, increased capillary recruitment, and better quality of life in many studies. Patients also had increased exercise capacity and a significant reduction in the use of narcotic drug use and daily anginal attacks in patients suffering from IAP. Copyright © 2020, Saini et al.Time-resolved contrast-enhanced magnetic resonance angiography (TRC-MRA) is a contrast-enhanced MRA technique commonly used for the qualitative hemodynamic assessment in digital subtraction angiography. TRC-MRA is a reliable method that seldom shows flow-related false findings which are sometimes observed on noncontrast or single-phase contrast-enhanced MRA techniques. Here we present a case of a patient with large fibroids that showed pseudo-occlusion of common iliac artery in TRC-MRA. Flow alternation can take place depending on patient posture and positioning status, especially in cases with large pelvic mass lesions. This is the first report of false image findings related to pelvic mass observed on TRC-MRA. For patient preparation, coil setting position is important and physicians should be familiar with the potential risk of transient arterial luminal stenosis or even occlusion in patients with large pelvic mass.

Methods A cross-sectional study was conducted at Dr. Ziauddin Hospital Clifton campus, Karachi. Patients visiting the liver clinic with disturbed liver enzymes and a history of alcohol intake after excluding other causes were included. A detailed history, routine investigations, insulin level, abdominal ultrasound, and transient elastography were performed. Results A total of 155 patients were included in the study, 98% of whom were men. The median age was 45.93 years (range 18-78 years). Just over three-fourths of the visiting patients were Muslim (n=119; 76.8%). The median duration of alcohol intake was 5.7 years. All patients admitted to consuming alcohol on an empty stomach before dinner. The most common associated addiction was smoking (n=95; 61.2%). Around two-thirds of patients confessed to binge drinking (n=66dependent. Insulin resistance was observed in a significant number of patients.

With more indications for cardiac implantable electrode devices, the devices themselves have evolved into more complex structures with more leads. The mechanical stress, risk of infection, and decreased blood flow through the superior vena cava (SVC) put patients at risk for SVC obstruction. Herein, we present a rare case of complete SVC obstruction secondary to fibrosis due to pacemaker leads which was treated with venoplasty and showed excellent long-term results. We also review the current literature on different approaches to treating SVC obstruction in this group of patients.

CNS TB is prevalent in the underdeveloped or developing world and is common in malnourished, alcoholics, children, young adults, immunocompromised, and cancer patients. Intracranial tuberculomas (ICT) can present with symptoms and signs of focal neurological deficits with or without systemic manifestations. ICT is the least common presentation of CNS TB. Medical management with anti-TB drugs and steroids is the mainstay of treatment, while surgical intervention is usually reserved for refractory cases. Here, we present the case of a 10-year-old Indian American girl with headaches, diplopia, fever, and neck pain diagnosed with ICT and intramedullary spinal cord tuberculoma.
