The clinical relevance of right ventricular diastolic function is introduced, with practical guidance for its assessment. Finally, the relatively novel techniques of three-dimensional right ventricular echocardiography and right ventricular speckle tracking imaging are described. Despite these techniques holding considerable promise, issues relating to reproducibility and inter-vendor variation have limited their clinical utility to date. British Society of Echocardiography 2020This guideline presents reference limits for use in echocardiographic practice, updating previous guidance from the British Society of Echocardiography. The rationale for change is discussed, in addition to how the reference intervals were defined and the current limitations to their use. The importance of interpretation of echocardiographic parameters within the clinical context is explored, as is grading of abnormality. Each of the following echo parameters are discussed and updated in turn left ventricular linear dimensions and LV mass; left ventricular volumes; left ventricular ejection fraction; left atrial size; right heart parameters; aortic dimensions; and tissue Doppler imaging. There are several important conceptual changes to the assessment of the heart’s structure and function within this guideline. New terminology for left ventricular function and left atrial size are introduced. The British Society of Echocardiography has advocated a new approach to the assessment of the aortic root, the right heart, and clarified the optimal methodology for assessment of LA size. The British Society of Echocardiography has emphasized a preference to use, where feasible, indexed measures over absolute values for any chamber size. The British Society of Echocardiography 2020Emergency clinicians must be aware of the current diagnostic and therapeutic recommendations for influenza and the available resources to guide management. This comprehensive review outlines the classification of influenza viruses, influenza pathophysiology, the identification of high-risk patients, and the importance of vaccination, with an update on the 2019-2020 influenza season. Seasonal variations of influenza are discussed, as well as the rationale for limiting testing during periods of high prevalence. Differences between strains of influenza are discussed, as well as the challenges in achieving optimal vaccine effectiveness. Recommendations for use of the currently available oral, intranasal, and intravenous antiviral treatments are provided, as well as utilizing shared decision-making with patients regarding risks and benefits of treatment.Prior to the global outbreak of SARS-CoV in 2003, HCoV-229E and HCoV-OC43 were the only coronaviruses known to infect humans. Following the SARS outbreak, 5 additional coronaviruses have been discovered in humans, most recently the novel coronavirus COVID-19, believed to have originated in Wuhan, Hubei Province, China. SARS-CoV and MERSCoV are particularly pathogenic in humans and are associated with high mortality. In this review, the epidemiology, pathophysiology, and management of the recently discovered COVID-19 are reviewed, with a focus on best practices and the public health implications.BACKGROUND The number of women with cosmetic breast implants has increased in recent decades in Norway. We compared the risk of detecting breast cancer and histopathological characteristics of the tumours in women with and without implants. #link# MATERIAL AND METHOD We retrieved information from the Cancer Registry's databases on implants and breast cancer among women who had participated in BreastScreen Norway in the period 1996-2016. Use of the data is pursuant to the Cancer Registry Regulations. We identified 785 706 women, of whom 10 086 (1.3 %) reported that they had an implant. We calculated the incidence rate ratio (IRR) with a 95 % confidence interval (95 % CI) for detected breast cancer and compared histopathological tumour characteristics among women with and without implants with the aid of descriptive analyses. RESULTS The incidence rate ratio for breast cancer was 30 % lower for women with implants than for women without (IRR 0.70 (95 % CI 0.60-0.81)). Women with implants who had cancer detected had tumours with a larger diameter than women without, and several of these women had metastasis to axillary lymph nodes. INTERPRETATION Women with implants who participated in BreastScreen Norway had a lower risk of detection of breast cancer, but more advanced disease upon diagnosis than those without implants. This may be due to the difficulty caused by implants in performing and interpreting the mammograms. find more should be informed about this before undergoing augmentation mammoplasty.Neurogenic bladder dysfunction is the cause of a small proportion of urinary problems in children. Various neurological conditions can result in a change in neural control of the bladder, and also the colon. Some of these conditions are apparent at birth; others are discovered later, and it is important that the primary health service be aware of them, so that targeted treatment can be provided.BACKGROUND Mammography screening has generated considerable professional and public debate. In this study, we investigate whether women receive sufficient information about the benefits and disadvantages of the Norwegian Breast Cancer Screening Program to enable them to make informed, independent choices. MATERIAL AND METHOD Informational material from the Norwegian Breast Cancer Screening Program for 1996, 2003, 2009 and 2017 was analysed and compared with information from the independent inquiry into the mammography screening programme headed by the Research Council of Norway. The criteria that are essential in order to make informed choices are as follows benefit (absolute and relative reduction in mortality), disadvantages (false-positive results, overdiagnosis, overtreatment and anxiety), implementation (following invitation, recall, and findings requiring treatment), and limitations (interval cancer). RESULTS Information provided to women has significantly improved from 1996 to 2017. Nevertheless, the information in 2017 lacks important details regarding the disadvantages of screening, such as overdiagnosis and overtreatment.
