BACKGROUND AND OBJECTIVE: Drug-induced anaphylaxis is an unpredictable and potentially fatal adverse drug reaction. The aim of this study was to identify the causes of drug-induced anaphylaxis in Portugal. METHODS: During a 4-year period a nationwide notification system for anaphylaxis was implemented, with voluntary reporting by allergists. Data on 313 patients with drug anaphylaxis were received and reviewed....
ResumoAs doenças pulmonares intersticiais (DPI) crónicas caracterizam-se por persistência ou recorrência de dispneia e/ou tosse, de desenvolvimento insidioso e duração superior a um mês, pela presença de infiltrados pulmonares bilaterais e por alterações das trocas gasosas. A prevalência na idade pediátrica é muito baixa e o diagnóstico etiológico e o tratamento são, em regra, difíceis. Em 1995, Katzenstein e c...

O hipertiroidismo é raro na idade pediátrica, aumentando a sua incidência na puberdade, sobretudo no sexo feminino. Uma das suas causas mais frequentes é a doença de Graves, cujo tratamento é ainda objecto de grande controvérsia, em todos os grupos etários, mas de forma ainda mais intensa na infância.Os autores fazem uma revisão dos cinco casos clínicos observados na Unidade de Endocrinologia Pediátrica do Hosp...
As raças Merina Branca e Merina Preta apresentam um potencial de produção de carne assinalável, aliado a características de rusticidade, longevidade e resistência a doenças. Animais explorados em regimes extensivos, muitas vezes associados ao ecossistema montado, poderão ter um papel importante no âmbito dos novos modos de produção sustentada (Programa de conservação / Melhoramento Genético, 2007). As estrongil...
Introdução: A fasceíte plantar (FP) constitui a causa mais frequente de dor no retropé. Está recomendada uma prova terapêutica inicial conservadora. Objetivos: Caraterizar fatores demográficos e sintomáticos, terapêutica prévia e resultados de monoterapia com laser. Material e Métodos: Estudo observacional retrospetivo (12 meses). O tratamento aplicado foi laser infravermelho (AsGa 904nm; densidade de energia 2...
The isolation of various two-dimensional (2D) materials, and the possibility to combine them in vertical stacks, has created a new paradigm in materials science: heterostructures based on 2D crystals. Such a concept has already proven fruitful for a number of electronic applications in the area of ultrathin and flexible devices. Here we expand the range of such structures to photoactive ones by utilizing semico...
In this work, three different natural fibers were studied and characterized, using optical and SEM microscopy. Woven fabrics of those reinforcement fibers were used to reinforce polyester and epoxy matrices and produce composite plates by vacum lay-up. Also, using an experimental piston blender equipment, long fiber reinforced PLA (LFT) composites were manufactured by hot compression molding. All different obta...
In this work, different natural fibres were studied and characterized, using optical and SEM microscopy. Those fibres were used to reinforce polyester and epoxy matrices and produce composite plates by hand lay-up. A vacuum bag was then used to allow improving the fibre impregnation, establishing a controlled pressure atmosphere. All different obtained composite plates were submitted to mechanical testing, in o...
Chloroanisoles, namely 2,4,6-trichloroanisole, are pointed out as the primary responsible of the development of musty off-flavours in bottled wine, due to their migration from cork stoppers, which results in huge economical losses for wine industry. A prevention step is the detection of these compounds in cork planks before stoppers are produced. Mass spectrometry gas chromatography is the reference method used...
