Parent-reported and clinician-observed autism spectrum disorder (ASD) symptoms in children with attention deficit/hyperactivity disorder (ADHD): implications for practice under DSM-5

BACKGROUND: Children with attention deficit/hyperactivity disorder (ADHD) often present with social difficulties, though the extent to which these clearly overlap with symptoms of autism spectrum disorder (ASD) is not well understood. METHODS: We explored parent-reported and directly-observed ASD symptoms on the Autism Diagnostic Interview-Revised (ADI-R) and the Autism Diagnostic Observation Schedule (ADOS) in children referred to ASD-specialty clinics who received diagnoses of either ADHD (n = 48) or ASD (n = 164). RESULTS: Of the ADHD sample, 21 % met ASD cut-offs on the ADOS and 30 % met ASD cut-offs on all domains of the ADI-R. Four social communication ADOS items (Quality of Social Overtures, Unusual Eye Contact, Facial Expressions Directed to Examiner, and Amount of Reciprocal Social Communication) adequately differentiated the groups while none of the items on the ADI-R met the criteria for adequate discrimination. CONCLUSIONS: Results of this work highlight the challenges that clinicians and researchers face when distinguishing ASD from other disorders in verbally fluent, school-age children

Integrating biodiversity, remote sensing, and auxiliary information for the study of ecosystem functioning and conservation at large spatial scales

Assessing patterns and processes of plant functional, taxonomic, genetic, and structural biodiversity at large scales is essential across many disciplines, including ecosystem management, agriculture, ecosystem risk and service assessment, conservation science, and forestry. In situ data housed in databases necessary to perform such assessments over large parts of the world are growing steadily. Integrating these in situ data with remote sensing (RS) products helps not only to improve data completeness and quality but also to account for limitations and uncertainties associated with each data product. Here, we outline how auxiliary environmental and socioeconomic data might be integrated with biodiversity and RS data to expand our knowledge about ecosystem functioning and inform the conservation of biodiversity. We discuss concepts, data, and methods necessary to assess plant species and ecosystem properties across scales of space and time and provide a critical discussion of outstanding issues

A importância da interação entre odontopediatrias e pediatrias no manejo de dentes natais e neonatais The importance of interaction of pediatric dentists and pediatricians in the management of natal and neonatal teeth

OBJETIVO: Apresentar revisão de literatura sobre dentes natais e neonatais, abordando características clínicas, fatores etiológicos, medidas terapêuticas e a importância do conhecimento desta anomalia, por odontopediatras e pediatras. FONTES DE DADOS: Foram selecionados os artigos mais relevantes sobre o tema, desde 1950 até 2006, pesquisados no Medline e na Bibliografia Brasileira em Odontologia (BBO), além de livros de pertinentes. SÍNTESE DOS DADOS: Os dentes natais e neonatais consistem em uma anomalia de erupção, sendo caracterizados por seu irrompimento na cavidade oral durante o período intra-uterino ou no primeiro mês de vida respectivamente, podendo fazer parte da dentição decídua normal ou supranumerária. Esses dentes, em geral, apresentam bordos cortantes e podem estar relacionados ao aparecimento de ulcerações na base da língua do bebê e/ou no seio materno, comprometendo a amamentação. A fraca implantação óssea desses dentes favorece sua grande mobilidade, tornando-se, assim, um fator de risco à sua aspiração ou deglutição pela criança. A abordagem terapêutica depende da dentição à qual pertence o dente e dos possíveis problemas que este pode causar à saúde da criança ou da mãe. CONCLUSÕES: O conhecimento sobre as características clínicas e os possíveis distúrbios aos quais os dentes natais e neonatais estão relacionados por odontopediatras e pediatras possibilita a interação necessária para o diagnóstico precoce e a abordagem integral da criança.<br>OBJECTIVE: To review available data about natal and neonatal teeth, emphasizing clinical characteristics, etiological factors, treatment, and the importance of the knowledge about this anomaly by pediatric dentists and pediatricians. DATA SOURCES: The most relevant articles published on the subject were selected, from 1950 to 2006, browsed on Medline, Brazilian Bibliografy of Odontology (BBO) and Dentistry books. DATA SYNTHESIS: Natal and neonatal teeth are considered eruption anomalies, characterized by eruption into oral cavity during the intrauterine period or during the first month after birth, respectively, being part of the regular deciduous or the supernumerary dentitions. As these teeth usually present cutting edges, they can be related to traumatic injury to newborn’s tongue and/or to mother’s nipples, compromising breastfeeding. In general, the weak attachment of these teeth to alveolar bone favors a high degree of mobility, which exposes the infant to the risk of aspiration or swallowing them. The management depends on which dentition these teeth belong and/or on complications that may affect either infant’s or mother’s health. CONCLUSIONS: The knowledge about the clinical characteristics and the possible complications related to natal and neonatal teeth by pediatric dentists and pediatricians provides the necessary interaction to early diagnosis and infant general management
