The coronavirus disease 2019 (COVID-19) outbreak was first identified in Wuhan in December 2019, which was declared a pandemic virus by the world health organization on March 11 in 2020. COVID-19 is an infectious disease and almost leads to acute respiratory distress syndrome. Therefore, the virus epidemic is a big problem for humanity healthy and can lead die in special people with background diseases such as chronic obstructive pulmonary diseases, chronic heart failure, diabetes mellitus, and kidney failure. Different medical, social, and engineering methods have been proposed to face the disease include treatment, detection, prevention, and prediction approaches. We propose a taxonomy tree to investigate the disease confronting methods and their negative and positive effects. Our work consists of a case study and systematic literature review (SLR) to evaluate the proposed methods against the virus outbreak and disease epidemic. Our experimental results and observations demonstrate the impact of the proposed medical, prevention, detection, prediction, and social methods for facing the spread of COVID-19 from December 2019 to July 2020. Our case study can help people have more information about the disease and its impact on humanity healthy and illustrate effective self-caring methods and therapies.Our case study can help people have more information about the disease and its impact on humanity healthy and illustrate effective self-caring methods and therapies. A challenging situation lies in front of every surgeon to perform emergency surgeries in a pandemic scenario. Gunshot injuries in a COVID-19 affected individual increases the chances of post-operative morbidity and mortality. Such cases require multidisciplinary approach with an advanced COVID care for the satisfactory outcome. We present a case of 30-year-old male with an alleged history of an accidental fire arm injury. His rapid antigen for COVID was positive. Contrast enhanced computed tomogram (CECT) abdomen was suggestive of multiple bowel injuries. Emergency exploratory laparotomy confirmed multiple bowel perforations with no associated solid organ injury. Perforated sites were sealed by primary repair and loop ileostomy was performed. Patient was discharged on post-operative Day 17 with satisfactory clinical improvement. Deleterious effects of COVID-19 has questioned the reliance on health care system across the globe. Pulmonary complications affect the post-operative course in patients undergoing surgery. However not every patient with peri operatively detected COVID-19 will have complicated post-operative course. Managing such patients with perioperative COVID-19 is an uphill task. Hemodynamic instability and clinical signs of peritonitis mandates the operative management. Multidisciplinary approach with advanced post-operative COVID care is required for satisfactory outcome. Management of patients undergoing emergency procedure with peri-operative COVID 19 is challenging for the attending surgeon. Consider all surgical emergencies as COVID positive unless proved otherwise. Multidisciplinary approach for management of COVID-19 infection along with good post-operative care is required.Management of patients undergoing emergency procedure with peri-operative COVID 19 is challenging for the attending surgeon.

E-cigarette, or Vaping, Product Use-Associated Lung Injury (EVALI) is a disease entity related to the use of battery-operated or superheating devices that create an aerosolized form of nicotine and tetrahydrocannabinol (THC) and/or other substances for inhalation. We performed a literature review to document epidemiology, pathogenesis and risk factors, diagnosis, clinical presentation, evaluation and management of EVALI. In the summer of 2019, an outbreak of EVALI cases brought this disease entity into the national spotlight. Since being recognized as a serious pulmonary disease with public health implications, more than 2600 cases have been reported to CDC with 68 deaths as of February 2020. The pathophysiology of EVALI remains unknown. Substances such as Vitamin E acetate have been implicated as a possible causes of lung injury. The CDC has established case definitions of "confirmed EVALI" cases to help guide identification of the disease and assist in surveillance. While clinical judgement by healthcare providers is imperative in the identification of EVALI cases, the heterogeneous presentations of EVALI make this difficult as well. Ultimately most investigative studies should be aimed at ruling out other disease processes that can present similarly. Treatment is centered around removing the offending substance and providing supportive care. EVALI is a serious pulmonary disease with public health implications. Diagnosis requires a high degree of suspicion to diagnose and exclusion of other possible causes of lung disease. It may be beneficial to involve a pulmonary specialist early in the management of this disease which is generally supportive care.EVALI is a serious pulmonary disease with public health implications.

This letter concisely outlines our response to the coronavirus pandemic, including the standard operating procedure we introduced and, at a trust level, the changes made to clozapine monitoring. We were surprised by the expectations of our patients during the pandemic we found that unwell patients or their carers would contact our service first, ahead of 111, primary care or emergency services for advice and treatment. Marimastat in vitro In response, we took on a deliberative first-responder role. Perhaps this is to be expected for a specialty that provides holistic long-term care to its patients. We think this is of interest to other mental health teams, primary care, community psychiatry teams and the lay reader.
