RESUMO

Congenital hemangiopericytoma (HPC) is a rare mesenchymal tumor with less aggressive behavior and a more favorable prognosis than similar tumors in adults. Multifocal presentation is even less common than isolated HPC and hence its clinical and histologic recognition may be challenging. A newborn infant with multifocal congenital HPC causing severe deformity but with a favorable outcome after chemotherapy and surgical removal is reported.

RESUMO

BACKGOUND/OBJECTIVES: The objective of the current study was to determine the relationship between serum vitamin D levels and the severity of atopic dermatitis (AD) in a Brazilian population. METHODS: This was a cross-sectional study of patients younger than 14 years of age seen from April to November 2013. All patients fulfilled the Hanifin and Rajka Diagnostic Criteria for AD diagnosis. Disease severity was determined using the SCORing Atopic Dermatitis index and classified as mild (<25), moderate (25-50), or severe (>50). Serum vitamin D levels were classified as sufficient (≥30 ng/mL), insufficient (29-21 ng/mL), or deficient (≤20 ng/mL). RESULTS: A total of 105 patients met the inclusion criteria. Mild AD was diagnosed in 58 (55.2%) children, moderate in 24 (22.8%), and severe in 23 (21.9%). Vitamin D deficiency was observed in 45 individuals (42.9%). Of these, 24 (53.3%) had mild AD, 13 (28.9%) moderate, and 8 (17.7%) severe. Insufficient vitamin D levels were found in 45 (42.9%) individuals; 24 (53.3%) had mild AD, 9 (20.0%) moderate, and 12 (26.7%) severe. Of the 15 individuals (14.2%) with sufficient vitamin D levels, 10 (60.7%) had mild AD, 2 (13.3%) moderate, and 3 (20.0%) severe. The mean vitamin D level was 22.1 ± 7.3 ng/mL in individuals with mild AD, 20.8 ± 6.5 ng/mL in those with moderate AD, and 21.9 ± 9.3 ng/mL in those with severe AD. Variables such as sex, age, skin phototype, season of the year, and bacterial infection were not significantly associated with vitamin D levels. CONCLUSION: Levels of 25-hydroxyvitamin D were deficient or insufficient in 85% of the children, but serum vitamin D concentrations were not significantly related to AD severity.

RESUMO

Nappy (diaper) rash is a common cutaneous disorder of infancy, and diverse dermatoses may affect this region. To perform a differential diagnosis can be challenging. We present four cases to emphasise the importance of clinical diagnosis.

RESUMO

Fusarium oxysporum has been described as a pathogen causing onychomycosis, its incidence has been increasing in immunocompetent and disseminated infection can occur in immunosuppressed individuals. We describe the first case of congenital onychomycosis in a child caused by Fusarium oxysporum. The infection being acquired in utero was proven by molecular methods with the identification of the fungus both in the nail and placenta, most probably as an ascending contamination/infection in a HIV-positive, immunosuppressed mother.

RESUMO

Não há consenso sobre quais são os valores ideais da vitamina D em crianças saudáveis. Porém, níveis séricos altos ou baixos parecem ter influência na fisiopatologia das doenças alérgicas. Há dados na literatura atual que demonstram os potenciais efeitos da vitamina D em aumentar a atividade dos peptídeos antimicrobianos e suprimir a resposta inflamatória, apontando uma relação inversa entre os níveis de vitamina D e a gravidade da dermatite atópica. O objetivo do presente trabalho foi revisar artigos publicados sobre a relação entre níveis séricos de vitamina D e dermatite atópica, uma vez que a vitamina D tem sido implicada em várias ações imunomoduladoras e alguns estudos têm descrito sua influência na gravidade da dermatite atópica, porém com resultados conflitantes. Este estudo baseou-se em revisão de artigos originais, artigos de revisão e consensos publicados nos últimos 10 anos, obtidos a partir da pesquisa dos termos “vitamin D” e “atopic dermatitis”, nos bancos de dados online. Concluímos que a suplementação da vitamina D pode trazer benefícios no tratamento da dermatite atópica. No entanto, mais pesquisas são necessárias para determinar se existe alguma relação entre os níveis de vitamina D e a gravidade da dermatite atópica.


There is no consensus about optimal values of vitamin D in normal children. However, high or low serum levels seem to influence the pathophysiology of allergic diseases. There is evidence supporting the potential effects of vitamin D on increasing the activity of antimicrobial peptides and suppressing the inflammatory response, indicating an inverse relationship between vitamin D levels and the severity of atopic dermatitis. Our objective was to review published articles on the relationship between serum vitamin D levels and atopic dermatitis, as vitamin D has been implicated in several immunoregulatory actions, and some studies have reported an influence on the severity of atopic dermatitis, with conflicting results. The present study reviewed original articles, review articles, and consensus documents published in the past 10 years, retrieved in online databases using the keywords “vitamin D” and “atopic dermatitis.” We conclude that vitamin D supplementation may be beneficial in the treatment of atopic dermatitis. However, more research is needed to determine whether there is any relationship between vitamin D levels and atopic dermatitis severity.
