Coexisting primary Sjögren’s syndrome and sarcoidosis: coincidence, mutually ex...

Herein, we describe a 44-year-old female diagnosed with histologically proven coexistence of primary Sjögren's syndrome and sarcoidosis with pulmonary and muscular involvement. The differential diagnosis may be difficult, but this is not an exceptional case, which highlights the need to critically revise the consideration of sarcoidosis as an exclusion for primary Sjögren's syndrome, as established in current c...

Amyand’s hernia: a case report

Amyand’s hernia, first described, in 1735, by Claudius Amyand, consists of an inguinal hernia with the appendix in its sac. It is a rare unknown disease, diagnosed mostly during surgery for treatment of the inguinal hernia. The authors present a case of a 38 year-oldman, who went to the emergency room, with an inguinal inflammatory tumor. He was diagnosed a strangulated inguinal hernia and proposed surgical tre...

Meningite a Meningococcus — Com esta Evolução?

A infecção por Neisseria meningitidis pode ter uma evolução atípica. A apresentação da doença sob a forma de gastroenterite aguda,numa criança de 6 anos, com evolução posterior para um quadro de cefaleias, sinais meníngeos e lateralização da marcha, motivaramo internamento ao 3° dia de doença. Os exames complementares realizados, Tomografia axial computorizada (TAC) cranio-encefálica epunção lombar (PL) foram n...

Structural, mechanical and dielectric properties of Ba0.6Sr0.4TiO3—The benefits...

This paper reports on the benefits gathered from a proper colloidal dispersion/deagglomeration of a Ba0.6Sr0.4TiO3 (BST) powder in water followed by spraying the aqueous suspension against liquid nitrogen to obtain homogeneous granules. The density of green compacts derived from the freeze granulated (FG) powder was compared with that of compacts prepared from the same starting BST powder but non-granulated (NG...

Impact strength of composites with nano-enhanced resin after fire exposure

Composite materials have been widely used in several engineering applications. However, there are very few studies about the effects of nanoclays on the impact strength of laminates after exposure to the fire. Therefore, this paper intends to study this subject and the impact performance was analysed by low velocity impact tests carried out at different incident impact energy levels. For better dispersion and i...

Descrição, factores, preditores e prognóstico dos derrames parapneumónicos

Resumo Introdução: A infecção pleural é um problema comum na prática clínica. Uma porção significativa das infecções no espaço pleural representa um processo progressivo que leva à transformação de um derrame simples em complicado. A maioria dos autores sugere que a decisão terapêutica depende do estadio de evolução da doença. Objectivos: Descrever e caracterizar os derrames parapneumónicos quanto à forma de ap...
