Fine Particulate Matter and Gaseous Compounds in Kitchens and Outdoor Air of Di...
Alves, C; Vicente, A; Oliveira, AR; Candeias, C; Vicente, E; Nunes, T; Cerqueira, M; Evtyugina, M; Rocha, F; Almeida, SMPassive diffusion tubes for volatile organic compounds (VOCs) and carbonyls and low volume particulate matter (PM2.5) samplers were used simultaneously in kitchens and outdoor air of four dwellings. PM2.5 filters were analysed for their carbonaceous content (organic and elemental carbon, OC and EC) by a thermo-optical technique and for polycyclic aromatic hydrocarbon (PAHs) and plasticisers by GC-MS. The morpho...
Optical Coeherence Tomography: a Window to Multiple Sclerosis?
Proença, R; Cardigos, J; Costa, L; Vicente, A; Santos, A; Amado, D; Ferreira, J; Cunha, JPIntroduction: Multiple sclerosis (MS) is an inflammatory immune-mediated demyelinating disease that frequently affects the central nervous system. Approximately 20% of patients have optic neuritis has the first manifestation of the disease. Its frequency, heterogeneity and absence of definitive treatment make it a therapeutic and diagnostic challenge for both the patient and the clinician. Material and methods:...
Macular Ganglion Cell Layer and Peripapillary Retinal Nerve Fibre Layer Thickne...
Anjos, R; Vieira, L; Costa, L; Vicente, A; Santos, A; Alves, N; Amado, D; Ferreira, J; Cunha, JPThe purpose of this study is to evaluate the macular ganglion cell layer (GCL) and peripapillary retinal nerve fibre layer (RNFL) thickness in patients with unilateral posterior cerebral artery (PCA) ischaemic lesions using spectral-domain optical coherence tomography (SD-OCT). A prospective, case-control study of patients with unilateral PCA lesion was conducted in the neuro-ophthalmology clinic of Centro Hosp...
Diabetic Choroidopathy: a Review of the Current Literature
Melancia, D; Vicente, A; Cunha, JP; Abegão Pinto, L; Ferreira, JDiabetic retinopathy is an increasingly prevalent disease, and a leading contributor to the burden of all-cause blindness worldwide. In addition to retinal changes, choroidal abnormalities are common in patients with diabetes. The first studies concerning this vascular structure were based on histologic, indocyanine angiography and laser Doppler flowmetry techniques, but the development of new optical coherence...
Correlação entre Espessura Macular e Camada de Fibras Nervosas Peripapilar no G...
Cabugueira, A; Vicente, A; Lemos, V; Anjos, R; Rosa, R; Flores, R; Gomes, T; Reina, MIntrodução: Os autores pretendem analisar a espessura macular e a camada de fibras nervosas peripapilar (CFN) em doentes com glaucoma inicial e com o diagnóstico de hipertensão ocular (HTO). Também propõem um modelo de correspondência da espessura macular de uma dada região do hemisfério superior com a CFN temporal superior (TS) e do hemisfério inferior com a CFN temporal inferior (TI) no glaucoma inicial. Mate...
The Impact of Multifocal Intraocular Lens in Retinal Imaging with Optical Coher...
Dias-Santos, A; Costa, L; Lemos, V; Anjos, R; Vicente, A; Ferreira, J; Cunha, JPMultifocal intraocular lenses (MF IOLs) have concentric optical zones with different dioptric power, enabling patients to have good visual acuity at multiple focal points. However, several optical limitations have been attributed to this particular design. The purpose of this study is to access the effect of MF IOLs design on the accuracy of retinal optical coherence tomography (OCT). Cross-sectional study cond...
Choroidal Thickness in Nonarteritic Anterior Ischaemic Optic Neuropathy: A Stud...
Dias-Santos, A; Ferreira, J; Abegão Pinto, L; Vicente, A; Anjos, R; Cabugueira, A; Flores, R; Cunha, JPNonarteritic anterior ischemic optic neuropathy (NA-AION) is the most common nonglaucomatous optic neuropathy in adults over 50 years of age. It is usually related to cardiovascular risk factors. The primary objective of this study was to evaluate choroidal thickness in patients with chronic NA-AION, and the secondary objective was to evaluate macular thickness in these patients. This cross-sectional study comp...
Optic Nerve Drusen: Find the Differences
Araújo, V; Vicente, A; Paixão, A; Martins, M; Toscano, AIntrodução: Os drusens do disco ótico são anomalias congénitas do desenvolvimento da cabeça do nervo ótico, correspondendo a depósitos hialinos calcificados, localizados anteriormente à lâmina crivosa. O seu diagnóstico é maioritariamente acidental, em doentes normalmente assintomáticos. Material e Métodos: Os autores apresentam 5 casos clínicos de doentes com idades de apresentação compreendidas entre 6 e 12 a...
Queratite por Acantamoeba - Revisão de 6 Casos Clínicos. Centro Hospitalar Lisb...
Anjos, R; Vicente, A; Vieira, L; Maduro, V; Alves, N; Feijão, J; Candelária, P; Trigo, MObjectivo: Determinar os factores de risco, características clínicas e desfecho da queratite por acantamoeba. Métodos: Os autores revêem os casos de queratite por acantamoeba em 6 doentes (3 do sexo masculino e 3 do sexo feminino) com idades compreendidas entre os 18 e os 41 anos, vigiados no Departamento de Córnea do nosso Hospital. As suas características e curso clínicos foram estudados retrospectivamente. R...
Kalirin: a novel genetic risk factor for ischemic stroke
Krug, T; Manso, H; Gouveia, L; Sobral, J; Xavier, J; Albergaria, I; Gaspar, G; Correia, M; Viana-Baptista, M; Simões, R; Pinto, A; Taipa, R; Ferreira, CCerebrovascular and cardiovascular diseases are the leading causes of death and disability worldwide. They are complex disorders resulting from the interplay of genetic and environmental factors, and may share several susceptibility genes. Several recent studies have implicated variants of the Kalirin (KALRN) gene with susceptibility to cardiovascular and metabolic phenotypes, but no studies have yet been perfo...
