Background and purposePhysical abuse of children, i.e., nonaccidental injury (NAI) including abusive head trauma (AHT) is experienced by up to 20% of children; however, only 0.1% are diagnosed. Healthcare professionals issue less than 20% of all reports suspecting NAI to the responsible authorities. Insufficient knowledge concerning NAI may partly explain this low percentage. The risk of NAI is heightened during health and socioeconomic crises such as COVID-19 and thus demands increased awareness. This review provides an overview and educational material on NAI and its clinical presentation.MethodsWe combined a literature review with expert opinions of the senior authors into an educational paper aiming to help clinicians to recognize NAI and act appropriately by referral to multidisciplinary child protection teams and local authorities.ResultsDespite the increased risk of NAI during the current COVID-19 crisis, the number of reports suspecting NAI decreased by 42% during the lockdown of the Danish society. Healthcare professionals filed only 17% of all reports of suspected child abuse in 2016.InterpretationThe key to recognizing and suspecting NAI upon clinical presentation is to be aware of inconsistencies in the medical history and suspicious findings on physical and paraclinical examination. During health and socioeconomic crises the incidence of NAI is likely to peak. Recognition of NAI, adequate handling by referral to child protection teams, and reporting to local authorities are of paramount importance to prevent mortality and physical and mental morbidity.

Physical abuse of children, i.e., non-accidental injury (NAI) including abusive head trauma (AHT), is experienced by up to 20% of children; however, only 0.1% are diagnosed with the ICD-10 code: T74.1 physical abuse (Christoffersen 2010, Stoltenborgh et al. 2013, Oldrup et al. 2016).During the current COVID-19 crisis some European countries have reported an alarming increase in domestic violence by one-third (Delaleu 2020). Likewise, the risk of NAI is heightened during health and socioeconomic crises (Baird 2020, Peterman et al. 2020). Therefore, a Joint Leaders’ statement by the World Health Organization, UNICEF, Save the Children International, and SOS Children’s Villages International among others, highlights the acute risk of violence against children due to COVID-19 and calls for increased awareness (World Health Organization 2020).The vast majority of NAI is reported by staff working at institutions (daycares, kindergartens, schools), which are temporarily closed during the COVID-19 pandemic. Healthcare professionals issue less than 20% of reports regarding suspected maltreatment to the responsible child protection authorities (Christoffersen 2010, Oldrup et al. 2016). Failure to recognize NAI due to insufficient knowledge among healthcare professionals may partly explain this low percentage (Villadsen et al. 2015).Healthcare professionals need to be aware of the increased risk of NAI during COVID-19 and future health and socio-economic crises in order to act appropriately based on current knowledge of the issue. Only then can they begin to recognize patterns of NAI from the medical history and objective findings, and act appropriately through immediate consultation and referral to multidisciplinary child protection teams, who can clarify the suspicion and ensure child protection.  相似文献

In this 14‐year retrospective study we analyzed samples collected from 101 adopted children originating from developing countries in search of dermatophytosis; a dermatophyte was isolated in 44 children. We demonstrated that dermatophytoses often have a silent clinical presentation (16%) and in approximately 20% of cases cause family member contamination. This study highlights the importance of the clinical examination of children and families as well as systematic sampling of children to avoid dermatophyte transmission to other family members.  相似文献

ABSTRACT

Introduction

Individuals with autism spectrum disorder (ASD) and intellectual disability (ID) seem to be at increased risk for post-traumatic stress disorder (PTSD), but knowledge is sparse regarding its identification in this population. Previous research indicates that certain symptoms of PTSD may be more easily recognized, and that identifying reexperiencing and avoidance is particularly challenging.  相似文献

Circulating tumor DNA (ctDNA) refers to the fraction of cell‐free DNA in a patient's blood originating from tumor cells. Increased knowledge about tumor genomics, improvements in targeted therapies, and accompanying advances in DNA‐sequencing technologies have increased the interest in using ctDNA as a minimally invasive tool in cancer diagnostics and treatment. Especially, early tumor detection including identification of minimal residual disease and stratification of adjuvant therapy are promising approaches. Also, ctDNA showed to be reliable in treatment monitoring and can be used to assess therapy resistance due to the broad variety of tumor subclones captured in ctDNA. Therefore, using ctDNA in the clinical setting has the potential to improve therapeutic outcomes. In the present review, we summarize the status of ctDNA in oncology with focus of being an alternative to tissue biopsies in early detection and treatment monitoring.  相似文献
