INTRODUÇÃO: O nosso objetivo foi avaliar as alterações vasculares coroideias em doentes com coriorretinopatia serosa central (CSC) utilizando tomografia de coerência ótica swept-source de campo alargado (WF SS-OCT) e angiografia de verde de indocianina de campo ultra-alargado (UWF ICGA). MÉTODOS: Estudo observacional prospetivo em doentes com CSC. Todos os doentes foram submetidos a UWF IGCA utilizando uma câma...
INTRODUCTION: Our aim was to assess optic disc structural, vascular and functional parameters in patients with primary Raynaud’s phenomenon (PRP). METHODS: This study enrolled patients with PRP and healthy age-matched controls. Subjects underwent evaluation of intraocular pressure (IOP), anterior chamber angle, optic disc structural and vascular parameters (measured by optical coherence tomography) and visual f...
INTRODUÇÃO : A retinopatia é a manifestação oftalmológica mais frequente da doença de células falciformes (DCF). Os avanços em imagem multimodal retiniana têm revelado a presença de retinopatia em doentes assintomáticos. O presente estudo tem como objetivo caracterizar as alterações retinianas típicas por imagem multimodal numa população pediátrica com DCF, permitindo observar os efeitos vascul...
Actuators using Shape Memory Alloy (SMA) springs could operate in different mechanical systems requiring geometric flexibility and high performance. The aim of the present study is to highlight the potential of these actuators, using their dimensional variations resulting from the phase transformations of NiTi springs (SMA) to make the movements of the system’s mobile components reversible. This reversibility i...
Purpose – The study investigates whether the level of sustainability concerns of Higher Education Institutions (HEIs) in Malaysia and the Philippines is positively associated with accounting students’ intentions to engage in sustainability accounting through its effect on students’ attitude, subjective norm and perceived behavioural control regarding environmental sustainability practices. Design/methodology/ap...
Shape Memory Alloys (SMAs) can play an essential role in developing novel active sensors for self-healing, including aeronautical systems. However, the NiTi SMAs available in the market are almost limited to wires, small sheets, and coatings. This restriction is mainly due to the difficulty in processing NiTi through conventional processes. Thus, the objective of this study is to evaluate the potential of one o...
Purpose: This work aims to study the impact of earnings quality on firms’ financial performance. Design/methodology/approach: An unbalanced panel data of 237 small and medium-sized Portuguese companies from the mold industry, using 2010-2018 yearly data was analyzed. While most studies focus only on earnings management when assessing earnings quality, in this study six proxies for earnings quality are used, nam...
Apresentamos um caso clínico de hipertensão intracraniana (HIC) numa criança com síndrome de Turner sob tratamento com hormona do crescimento (HC). Criança de 14 anos com síndrome de Turner sob terapêutica hormonal com estrogénio e hormona de crescimento (1,6 mg/dia) apresentou-se no serviço de urgência por diminuição da acuidade visual. A fundoscopia revelou edema bilateral da papila, confirmada po...
Introduction: Our purpose was to evaluate the effect of eye rubbing discontinuation on the epithelial thickness profile by spectral-domain AS-OCT (anterior segment optical coherence tomography) in allergic children with no tomographic sign of corneal ectasia. Methods: Right-handed boys (average age 11.2 years, 8-12 years) with history of eye rubbing and relatively normal Pentacam (Oculus; Wetzlar, Germany) ex...
Introdução: O eritema nodoso consiste numa erupção cutânea eritematosa aguda, do tipo nodular, que habitualmente se encontra limitada à face anterior das pernas. As principais causas são as infeções estreptocócicas nas crianças e as infeções estreptocócicas e a sarcoidose nos adultos.Descrição do caso: Os autores apresentam o caso de uma mulher de 33 anos, encaminhada a partir do serviço de urgência por poliart...
