Recent advances in epidemiology and prevention of atopic eczema
No full textAtopic dermatitis (AD), named also atopic eczema, is a chronic relapsing inflammatory skin disease with a considerable social and economic burden. The primum movens of AD is in most cases a genetic and/or immune-supported defect of the skin barrier, facilitating penetration and sensitization to food or airborne allergens, as well as infections by Staphylococcus aureus, herpes simplex virus, or other microbes. New pathogenetic concepts have generated new approaches to prevention and therapy of AD. In particular, the daily use of emollients in newborns at high risk of AD has shown interesting results, with a reduction in the cumulative incidence of AD ranging from 32% to 50% of the treated infants. On the other hand, the AD preventive efficacy of food and/or inhalant allergen avoidance has been questioned, and supplementation strategies (vitamin D, probiotics, or other compounds) need to be further investigated
Drug rash with eosinophilia and systemic symptoms (DRESS) syndrome in childhood: a narrative review
Full text linkDespite being rare, the Drug Rash with Eosinophilia and Systemic Symptoms (DRESS) syndrome is a serious, possibly fatal condition that may affect both adults and children who may be also burdened by delayed sequelae. It is an adverse drug reaction characterized by widespread skin involvement, fever, lymphadenopathy, visceral involvement, and laboratory abnormalities (eosinophilia, mononucleosis-like atypical lymphocytes). It is more frequently triggered by anticonvulsants, sulphonamides, or antibiotics, the latter being responsible for up to 30% of pediatric cases. The disease typically develops 2-8 weeks after exposure to the culprit medication, with fever and widespread skin eruption; mild viral prodromes are possible. Unfortunately, diagnosis is challenging due to the absence of a reliable test; however, a score by the European Registry of Severe Cutaneous Adverse Reactions (RegiSCAR) allows to classify suspect patients into no, possible, probable, or definite DRESS cases. Moreover, rapid-onset DRESS syndrome has been described in recent years. It affects children more often than adults and differs from the most common form because it appears & LE;15 days vs. >15 days after starting the drug, it is usually triggered by antibiotics or iodinated contrast media rather than by anticonvulsants and has a higher presence of lymphadenopathy. Differential diagnosis between rapid-onset antibiotic-driven DRESS syndrome, viral exanthems, or other drug eruptions may be challenging, but it is mandatory to define it as early as possible to start adequate treatment and monitor possible complications. The present review reports the latest evidence about the diagnosis and treatment of pediatric DRESS syndrome

Atypical forms of hand, foot, and mouth disease: A prospective study of 47 Italian children
No full textBackground: Atypical forms of hand, foot, and mouth disease (HFMD) caused by coxsackievirus A6 have been reported in recent years. High fever and severe cutaneous lesions are common, whereas neurologic complications are rare. Eczematous areas of patients with atopic dermatitis show more lesions. The goal of the current study was to describe the clinical characteristics of children with atypical HFMD and to investigate the involvement of the different enterovirus serotypes associated. Methods: All patients referred to our service for atypical HFMD from January 2012 to February 2014 were enrolled and classified as having the diffuse form (lesions extended to the trunk), the acral form (lesions with a mainly acral distribution), or eczema coxsackium (lesions on preexisting eczematous areas). Results: Data from 47 patients were analyzed (median age 22 months [range 4–84 mos]); viral genotyping was performed in 11 cases. Sixty-two percent of the subjects developed the acral form, 23% eczema coxsackium, and 15% the diffuse form. Most patients had a nonclassical vesicular eruption and moderate to severe extent of cutaneous involvement. Approximately 80% of patients had palmoplantar purpuric macules. Most children younger than 2 years old had the acral form, most patients with eczema coxsackium were age 2 years and older, and the diffuse form was similarly distributed between the two age groups. Coxsackievirus A6 was detected in 9 of 11 genotyped cases. Conclusion: Our prospective study allowed the identification of three HFMD phenotypes differing from the classical form. Clinical care of these patients should include symptomatic treatment of extracutaneous features and, if necessary, hospitalization for complications
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
The first 1000 days: the price of inequalities in high and middle-income countries
Full text linkAbstract: The first 1000 days of human life start from conception until the child turns 2 years of age. This is a unique period in which the foundations of a child’s lifelong health are built. Disadvantaged socioeconomic circumstances and limited access to health care services can globally affect a child’s health outcomes and educational and vocational potential. This article discusses health inequalities over the first 1000 days of life and possible mitigation programs. Governments and politicians should promote fairer health interventions and pediatric healthcare workers should be aware of the main health determinants to advocate for more equitable and child-focused resource allocation. Therefore, the main approaches to contrast health inequalities include cooperation between governments and public health professionals, removing barriers to accessing medical care, and raising staff awareness about health determinants. Finally, pro-equality interventions should include providing services commensurate with the level of need, in adherence to the principle of social justice. Impact: This review aims to elicit a detailed understanding of how inequalities affect early childhood development in different socio-economic contexts, focusing on both the short and long-term consequences. The greatest impact comes precisely from providing valuable tools for both clinicians and public health practitioners to understand and read, in daily practice, the effects produced by health determinants and health inequalities
