The 2019 coronavirus infection (called SARS-CoV-2) began in Wuhan, spread rapidly throughout the world. In many countries the exponential growth of Covid-19 cases is overwhelming health care systems with overcrowding of hospitals and overflowing Intensive Care Units. While people must stay at home to reduce the spread of this virus health-care workers do the exact opposite. In some countries doctors are working with insufficient protection and are constantly at risk of contracting Covid-19. Health-care workers should be constantly monitored because if they are infected they may spread the virus to colleagues, hospitalized patients and even family members. Increased rates of infection in health-care workers could cause the health-care system to collapse and a further worsening of the pandemic; if there are too few doctors it will be even more difficult to manage.

Background Abdominal aortic aneurysm (AAA) is a complex multi-factorial disease with life-threatening complications. AAA is typically asymptomatic and its rupture is associated with high mortality rate. Both environmental and genetic risk factors are involved in AAA pathogenesis. Aim of this study was to investigate telomere length (TL) and oxidative DNA damage in paired blood lymphocytes, aortic endothelial cells (EC), vascular smooth muscle cells (VSMC), and epidermal cells from patients with AAA in comparison with matched controls.MethodsTL was assessed using a modification of quantitative (Q)-FISH in combination with immunofluorescence for CD31 or α-smooth muscle actin to detect EC and VSMC, respectively. Oxidative DNA damage was investigated by immunofluorescence staining for 7, 8-dihydro-8-oxo-2′-deoxyguanosine (8-oxo-dG).Results and ConclusionsTelomeres were found to be significantly shortened in EC, VSMC, keratinocytes and blood lymphocytes from AAA patients compared to matched controls. 8-oxo-dG immunoreactivity, indicative of oxidative DNA damage, was detected at higher levels in all of the above cell types from AAA patients compared to matched controls. Increased DNA double strand breaks were detected in AAA patients vs controls by nuclear staining for γ-H2AX histone. There was statistically significant inverse correlation between TL and accumulation of oxidative DNA damage in blood lymphocytes from AAA patients. This study shows for the first time that EC and VSMC from AAA have shortened telomeres and oxidative DNA damage. Similar findings were obtained with circulating lymphocytes and keratinocytes, indicating the systemic nature of the disease. Potential translational implications of these findings are discussed.

Retronychia represents proximal ingrowth of the nail that occurs when the nail embeds backwards into the proximal nail fold. It is suspected when there is a persistent paronychia, particularly in the setting of trauma. Important clinical criteria for diagnosis are inflammation of the proximal nail fold, granulation tissue emerging from under the nail fold, thickening of the proximal portion of the nail plate and interruption of nail growth. The condition is rarely diagnosed and often misinterpreted, and is therefore unnecessarily treated with systemic antibiotics and antifungals. Avulsion of the nail confirms the diagnosis and it is the curative treatment. Conservative treatment with an adhesive technique is a valid option in early cases. We report 20 cases of retronychia diagnosed in our department between 2010 and 2013.

Despite numerous measures to contain the infection and limit its spread, cases of SARS-CoV-2 infections acquired in hospitals have been reported consistently. In this paper, we will address issues of hospital-acquired COVID-19 in hospitalized patients as well as medico-legal implications. After having conducted a literature search, we will report on papers on hospital-acquired SARS-CoV-2 infections. Ten scientific papers were selected and considered suitable for further analysis. According to several reports, the SARS-CoV-2 hospital-acquired infection rate is 12–15%. Hospital-acquired COVID-19 represents a serious public health issue, which is a problem that could create reluctance of patients to seek hospital treatment for fear of becoming infected. Healthcare personnel should do all that is necessary to address the problem and prevent further spreading, such as rigorous compliance with all procedures for containing the spread. From a medical-legal point of view, multiple aspects must be considered in order to understand whether the infection is a result of “malpractice” or an inevitable condition.
