Currently, CEUS (Contrast-Enhanced UltraSound) is used in the evaluation of different organs and systems. It offers valuable information about vascular disease, both on a macro- and a micro-vascular level, and has a series of well-established applications in the monitoring of adult patients; official guidelines and recommendations are also available. Its use in a nephrological setting is constantly growing thanks to the lack of nephrotoxicity of the contrast agent, the absence of ionizing radiation and the possibility of characterizing focal pathologies, for diagnosis and in clinical practice. We describe here 3 clinical cases relating to renal diseases and we review the relevant literature with a specific focus on the use of CEUS in a nephro-urological setting.Considerable efforts have been undertaken to quickly develop COVID-19 vaccines that protect vulnerable adults against severe disease and thus limit the socio-economic and public health impact of the current pandemic. To justify COVID-19 vaccination for the pediatric population, which rarely suffers from severe COVID-19, vaccines will need to have fully demonstrated safety and efficacy in preventing complications and viral transmission. This article summarizes the different vaccine platforms that are currently being tested and discusses practical and ethical aspects of childhood COVID-19 vaccination. It also examines the already deleterious effects of the pandemic on routine childhood vaccine coverage and insists on the imperative to vaccinate all children timely as recommended by national immunization programs.In this article, the authors, a pediatrician/child psychiatrist and two psychiatrists trained in systemic family therapies, share their reflections on the psychological effects of the COVID-19 pandemic on children and family ties. The therapists review the literature, draw upon their clinical experience during the first wave of the pandemic to suggest some guidelines for this second wave. A clinical case illustrates their practice with an example of family resilience. The importance of the healthcare network in strengthening family resilience is also highlighted.Although SARS-CoV-2 infects individuals of all ages, children show less severe symptoms. Nevertheless, the very rare COVID-19 severe cases in paediatrics require our full attention. Much research has been conducted and is still ongoing on effective treatments. On the antiviral front, no molecule has been proven effective yet and the results of several studies on the benefit of monoclonal antibodies and convalescent plasma are pending. On the side of immunomodulators, the benefit of steroids has been demonstrated for patients severely ill. Other molecules are being investigated. However, all these studies focused on adults and paediatric data are warranted.Some uncertainties remain regarding SARS-CoV-2 diagnostic procedures and seroprevalence studies in children. RT-PCR assays conducted on nasopharyngeal (NP) swabs remain the gold standard for SARS-CoV-2 diagnostic in children as in adults. Saliva samples might replace soon NP swabs as similar sensitivities have been reported from both samples in adults, but not yet in children. Rapid antigen testing is currently performed on NP swabs collected from children within 4 days of their symptom onset. Serology testing is an essential diagnostic tool in seroprevalence studies, which might guide in the future public health decisions.Children appeared to be initially spared by the SARS-CoV-2 pandemic, however, in spring 2020, a new clinical entity was described related to the SARS-CoV-2 infection and named multisystem inflammatory syndrome in children (MIS-C) or pediatric inflammatory multisystem syndrome (PIMS). The gravity of this inflammatory syndrome, the time interval between infection and MIS-C, the response to the various immunomodulatory treatments are all suggestive of an immunologic reaction rather than a virus-mediatred phenomenon. The pathophysiological mechanisms and possible risk factors for MIS-C have not been elucidated. In this article, we summarize what is known to date about the immune response to SARS-CoV-2 in children and about the immune response to SARS-CoV-2 in children and about the MIS-C.Children are under-represented in terms of the frequency and severity of COVID-19 disease. Although the proportion of children tested positive remains much lower than that of adults suggesting that they are less susceptible to SARS-CoV-2 infection, seroprevalence studies are contradictory in this regard. CX-5461 nmr With respect to the role of children in transmission of the virus, no biological reason for reduced infectivity has been found. However, in the community, children rarely seem to be the vectors of this infection. With regard to adolescents, epidemiological data and their behavior similar to that of young adults suggest that they contribute to the spread of the virus more effectively than younger children.

The aim of this study was to evaluate the clinical performance of two bulk-fill composite resins in Class II cavities for up to twenty-four months.

In total 75 Class II restorations were made in 25 patients using two nanohybrid bulk-fill resin composites and a microhybrid composite. The restorations were evaluated at baseline and at 6, 12, and 24 months, using U.S. Public Health Service (USPHS) criteria. The restoration groups were compared using the Pearson chi-square test, and the Cochran Q-test was used to compare the changes across different time points within restorative materials (p⟨0.05).

Two patients who did not attend the appointments were excluded from the study, so 23 patients were evaluated with a 92% recall rate; at the end of the two-year follow-up, 66 restorations were evaluated. Three restorations underwent endodontic treatment and were deemed failures. The overall success rate was 96%. There were statistically significant differences between the three restorative resins in terms of color match parameter (p⟨0.05). No differences were observed between the restorative resins in terms of other criteria (p⟩0.05).

During the two-year follow-up period, the three composite resins showed similar clinical performance except for the color match parameter.
