Since December 2019, the world has been facing the life-threatening disease, named Coronavirus disease-19 (COVID-19), recognized as a pandemic by the World Health Organization. The response of the Emergency Medicine network, integrating "out-of-hospital" and "hospital" activation, is crucial whenever the health system has to face a medical emergency, being caused by natural or human-derived disasters as well as by a rapidly spreading epidemic outbreak. We here report the Pavia Emergency Medicine network response to the COVID-19 outbreak. The "out-of-hospital" response was analysed in terms of calls, rescues and missions, whereas the "hospital" response was detailed as number of admitted patients and subsequent hospitalisation or discharge. The data in the first 5 weeks of the Covid-19 outbreak (February 21-March 26, 2020) were compared with a reference time window referring to the previous 5 weeks (January 17-February 20, 2020) and with the corresponding historical average data from the previous 5 years (February 21-March 26). Since February 21, 2020, a sudden and sustained increase in the calls to the AREU 112 system was noted (+ 440%). After 5 weeks, the number of calls and missions was still higher as compared to both the reference pre-Covid-19 period (+ 48% and + 10%, respectively) and the historical control (+ 53% and + 22%, respectively). Owing to the overflow from the neighbouring hospitals, which rapidly became overwhelmed and had to temporarily close patient access, the population served by the Pavia system more than doubled (from 547.251 to 1.135.977 inhabitants, + 108%). To minimize the possibility of intra-hospital spreading of the infection, a separate "Emergency Department-Infective Disease" was created, which evaluated 1241 patients with suspected infection (38% of total ED admissions). Out of these 1241 patients, 58.0% (n = 720) were admitted in general wards (n = 629) or intensive care unit (n = 91). To allow this massive number of admissions, the hospital reshaped many general ward Units, which became Covid-19 Units (up to 270 beds) and increased the intensive care unit beds from 32 to 60. In the setting of a long-standing continuing emergency like the present Covid-19 outbreak, the integration, interaction and team work of the "out-of-hospital" and "in-hospital" systems have a pivotal role. The present study reports how the rapid and coordinated reorganization of both might help in facing such a disaster. AREU-112 and the Emergency Department should be ready to finely tune their usual cooperation to respond to a sudden and overwhelming increase in the healthcare needs brought about by a pandemia like the current one. This lesson should shape and reinforce the future.

In routine clinical practice, hepatitis C virus-infected patients can prematurely discontinue the prescribed regimen for several reasons. The aim of our study was to investigate sustained virological response (SVR12) rates in patients who prematurely discontinued directly acting antiviral (DAA) regimens and to assess the shortest effective duration of DAA able to lead to SVR12. We retrospectively collected the SVR rates of patients, registered in the NAVIGATORE-Lombardia Network database from January 2015, who discontinued DAAs before the predefined end of treatment. Overall, we included 365 patients, males were the majority (213, 58.4%), mean age was 60.5years, and 53 (14.5%) patients were HIV-co-infected. Liver cirrhosis was observed in 251 (68.8%) subjects, and the most represented genotypes were 1b (n=168, 46%) and 3 (n=59, 16.2%). DAA was discontinued a median of 1 (IQR 1–4) weeks before the predefined EOT, with 164 (44.9%) patients stopping DAAs at least 2weeks before the planned schedule. In patients with F0–F3 liver fibrosis, lower rates of SVR12 were observed in patients treated for

Objective: This study aimed to assess the role of Tocilizumab therapy (TCZ) in terms of ICU admission and mortality rate of critically ill patients with severe COVID-19 pneumonia. Design: Patients with COVID-19 pneumonia were prospectively enrolled in SMAtteo COvid19 REgistry (SMACORE). A retrospective analysis of patients treated with TCZ matched using propensity score to patients treated with Standard Of Care (SOC) was conducted. Setting: The study was conducted at IRCCS Policlinico San Matteo Hospital, Pavia, Italy, from March 14, 2020 to March 27, 2020. Participants: Patients with a confirmed diagnosis of COVID-19 hospitalized in our institution at the time of TCZ availability. Interventions: TCZ was administered to 21 patients. The first administration was 8 mg/kg (up to a maximum 800 mg per dose) of Tocilizumab intravenously, repeated after 12 h if no side effects were reported after the first dose. Main Outcomes and Measures: ICU admission and 7-day mortality rate. Secondary outcomes included clinical and laboratory data. Results: There were 112 patients evaluated (82 were male and 30 were female, with a median age of 63.55 years). Using propensity scores, the 21 patients who received TCZ were matched to 21 patients who received SOC (a combination of hydroxychloroquine, azithromycin and prophylactic dose of low weight heparin). No adverse event was detected following TCZ administration. This study found that treatment with TCZ did not significantly affect ICU admission (OR 0.11; 95% CI between 0.00 and 3.38; p = 0.22) or 7-day mortality rate (OR 0.78; 95% CI between 0.06 and 9.34; p = 0.84) when compared with SOC. Analysis of laboratory measures showed significant interactions between time and treatment regarding C-Reactive Protein (CRP), alanine aminotransferase (ALT), platelets and international normalized ratio (INR) levels. Variation in lymphocytes count was observed over time, irrespective of treatment. Conclusions: TCZ administration did not reduce ICU admission or mortality rate in a cohort of 21 patients. Additional data are needed to understand the effect(s) of TCZ in treating patients diagnosed with COVID-19.

Coronavirus disease 2019 (COVID‐19) diagnosis is based on molecular detection of SARS‐CoV‐2 in respiratory samples such as nasal swab (NS) However, the evidence that NS in patients with pneumonia was sometimes negative raises the attention to collect other clinical specimens SARS‐CoV‐2 was shown in 10 3% rectal swabs (RS), 7 7% plasma, 1% urine, and 0% feces from 143 NS‐positive patients Potential infection by fluids different from respiratory secretion is possible but unlikely [ABSTRACT FROM AUTHOR] Copyright of Pediatric Allergy & Immunology is the property of Wiley-Blackwell and its content may not be copied or emailed to multiple sites or posted to a listserv without the copyright holder's express written permission However, users may print, download, or email articles for individual use This abstract may be abridged No warranty is given about the accuracy of the copy Users should refer to the original published version of the material for the full abstract (Copyright applies to all Abstracts )

We report a case of a newborn, affected by tuberous sclerosis complex, with a prenatally diagnosed giant cardiac rhabdomyoma associated with a large renal angiomyolipoma presenting as a duct-depending lesion not treatable by surgery. After receiving everolimus, a mammalian target of rapamycin inhibitor, we observed a rapid, significant, and durable reduction of both lesions without remarkable side effects.

Objective: Augmentation of pulmonary blood flow is the only surgical treatment to reduce symptoms of cyanosis in patients with cavopulmonary connection unsuitable for Fontan operation. Brachial arteriovenous fistula is a good option to increase pulmonary blood flow. In this report, we analyze its possible consequences on ventricular function. Methods: Six patients considered unsuitable for a Fontan completion because of poor ventricular function underwent brachial arteriovenous fistula. The fistula was performed with the interposition of a 4-mm gore-tex conduit between the brachial vein and the brachial artery. Results: The mean oxygen saturation increased from 76.8 ± 1.9% to 84.1 ± 1.4% (p < 0.01); hemoglobin and hematocrit decreased from 21.13 ± 0.7 g/dL to 18.12 ± 0.5 g/dL (p < 0.01) and from 63.3 ± 2.7% to 54.2 ± 0.7% (p < 0.01), respectively. Mean ejection fraction and shortening fraction increased from 38.6 ± 1.5% to 49.5 ± 2.3% (p < 0.01) and from 23.3 ± 1.8% to 28.8 ± 1.3% (p < 0.01), respectively. A Fontan completion and takedown of the fistula was then accomplished, within six years, with no mortality or major complications. At a mean follow-up of 15 months, all six patients are clinically in good condition. Conclusion: In patients with a cavopulmonary connection and poor ventricular function, the brachial arteriovenous fistula may play a role in increasing oxygen saturation, optimizing ventricular preload, and reducing blood viscosity and pulmonary arteriovenous malformations. This approach might represent an intermediate step to rescue patients previously considered unsuitable or at high risk for Fontan operation. © 2011 Wiley Periodicals, Inc.

Congenital heart diseases are corrected early in life, so the surgical procedure has to maintain the maximum potential for growth. The quest for the ideal material for cardiac tissue repair is still ongoing. Here, we describe our preliminary experience with an extracellular matrix for cardiac and vascular tissue repair. Between August 2009 and April 2011, 26 patients underwent cardiac surgery using the CorMatrix patch for vascular repair (10 pulmonary artery, four ascending aorta, three aortic arch and one right ventricular outflow tract) or for valve reconstruction (five aortic, two tricuspid, one mitral and one pulmonary valve); in four cases, the repair was associated with pericardial closure using the same patch. There were no deaths, and at a mean follow-up of 13.2months, there was no evidence of patch-related complications either in the vascular position or when used for valve repair. The ideal material for cardiac tissue repair should be haemostatic and resistant to tearing and calcification, and possibly one that will not induce an inflammatory cascade. In the last 25months, we used an extracellular matrix for cardiac and vascular tissue repair. The patch is advocated to induce the patient's own tissue regeneration. The early results are encouraging, but a longer follow-up is needed to understand the real potential of this material. © 2011 Published by European Association for Cardio-Thoracic Surgery.

Many surgical techniques have been described either to repair and to replace the aortic valve. Among the paediatric population the potential for growth has to be preserved and valve reconstruction is therefore of great importance. In the last two years 25 consecutive patients, mean age 8.6 years, with aortic valve disease, underwent aortic valve repair for aortic regurgitation (AR) (10 patients), aortic valve stenosis (5 patients) or mixed lesion (10 patients). None of the patients died neither during hospitalization nor at follow-up (median 9.25 months). In the aortic stenosis (AS) group, one patient required reoperation (re-repair). None of the patients in the AR group developed more than mild AS and mild AR during follow-up. Nine out of 10 patients of the mixed lesion group had no or trivial AR at the follow-up. Left ventricular dimension decreased in all patients after repair. With a better understanding of the causes of AS or AR and the adoption of different techniques, often used in multiple association, we believe that aortic valve repair can be achieved in most patients with a normal left ventricular outflow tract. © 2010 Published by European Association for Cardio-Thoracic Surgery.

Objective: Mitral valve prolapse is a rare condition and represents a challenge for cardiac surgeons. Many techniques have been described to treat the wide spectrum of abnormalities causing mitral valve regurgitation but the low incidence of these abnormalities is the cause of the relatively poor experience of many institutions. Methods: From April 2005 to September 2006, five patients underwent isolated mitral valve repair with the edge-to-edge technique for anterior or bileaflet prolapse. Three patients also had a Gore-Tex strip to reinforce the posterior annulus, whereas two had a 26-size soft incomplete ring annuloplasty. Results: There was no death and none of the patients required reoperation. None of the patients had mitral regurgitation more than 1+ at a mean follow-up of 30 months. None of the patients had mitral stenosis or any valve-related event. Conclusion: The edge-to-edge technique is a well tolerated and useful technique for the anterior or bileaflet prolapse of the mitral valve. Although many techniques have been described with good results, in many anatomical settings and in small patients, edge-to-edge is a good option and might not interfere with the growth of the valve. Early results are encouraging but a longer follow-up is needed to evaluate the long-term prognosis. © 2009 Italian Federation of Cardiology.

Plastic bronchitis is a rare complication of a variety of respiratory diseases and congenital heart disease surgery, particularly Fontan procedure. Bronchial casts with rubber-like consistency develop acutely and may cause severe life-threatening respiratory distress. The management of plastic bronchitis is yet not well defined. Early intermittent, self-administered nebulization of tissue plasminogen activator was found to be effective in preventing deterioration of acute respiratory symptoms in a patient with primary ciliary dyskinesia and recurrent cast formation. Further investigation into new therapeutic strategies for this devastating disease is advocated. © 2014 Colaneri et al.; licensee BioMed Central Ltd.
