Added value of lymphocyte subpopulations in the classification of Sjögren's syn...
Barcelos, F; Brás-Geraldes, C; Martins, C; Papoila, AL; Monteiro, R; Cardigos, J; Madeira, N; Alves, N; Vaz-Patto, J; Cunha-Branco, J; Borrego, LMSjögren's Syndrome (SjS) is a chronic systemic immune-mediated inflammatory disease characterized by lymphocytic infiltration and consequent lesion of exocrine glands. SjS diagnosis and classification remains a challenge, especially at SjS onset, when patients may have milder phenotypes of the disease or uncommon presentations. New biomarkers are needed for the classification of SjS, thus, we aimed to evaluate ...

Corneal Sub‐Basal Nerve Plexus Assessment and its Association with Phenotypic F...
Barcelos, F; Hipólito‐Fernandes, D; Martins, C; Ângelo‐Dias, M; Cardigos, J; Monteiro, R; Alves, N; Vaz‐Patto, J; da Cunha‐Branco, J; Borrego, LMlPurpose: To assess and compare corneal sub-basal nerve plexus morphology with circulating lymphocyte subsets, immunologic status and disease activity in Sjögren syndrome (SjS) patients. Methods: Fifty-five SjS patients, 63 Sicca patients (not fulfilling SjS criteria), 18 rheumatoid arthritis (RA) patients and 20 healthy controls (HC) were included. Systemic disease activity in SjS was assessed with the ESSDAI s...
Association between EBV serological patterns and lymphocytic profile of SjS pat...
Barcelos, F; Martins, C; Monteiro, R; Cardigos, J; Prussiani, T; Sítima, M; Alves, N; Vaz-Patto, JA; Cunha-Branco, J; Borrego, LMSjögren's syndrome (SjS) is characterized by lymphocytic infiltration of exocrine glands, i.e. autoimmune epithelitis. Lymphocytes are central in SjS pathogenesis, with B-cell hyperactivity mediated by T-cells. B-cells are main targets of Epstein-Barr virus (EBV) infection, a frequently-suggested trigger for SjS. We aimed to evaluate how the EBV infection modulates B and T-cell subsets in SjS, including as cont...
Lymphocyte Subpopulations in Sjögren’s Syndrome Are Distinct in Anti-SSA-Positi...
Barcelos, F; Martins, C; Madeira, N; Dias, M; Cardigos, J; Alves, N; Vaz-Patto, J; Cunha-Branco, J; Borrego, LMObjectives: Sjögren's syndrome (SjS) patients exhibit great phenotypical heterogeneity, reinforced by the positiveness of anti-SSA antibody. We aimed to evaluate lymphocyte subpopulations in SSA-positive (SSA+SjS) and SSA-negative (SSA-SjS) SjS patients, Sicca patients, and healthy controls (HC), and to investigate associations between lymphocyte subpopulations and disease activity in SjS. Methods: According to...
Nanotechnology-Ocular Devices for Glaucoma Treatment: A Literature Review
Cardigos, J; Ferreira, Q; Crisóstomo, S; Coelho, N; Cunha, JP; Abegão Pinto, L; Ferreira, JNanotechnology enabled the development of materials and devices with great utility in different fields of medicine. By using engineered-based nano-devices and structures, human biological systems may be controlled and repaired at a molecular scale, ultimately leading to a biological benefit. In particular, in the field of glaucoma treatment, nanotechnology may, for example, enhance drug residence time on the oc...
Bilateral Metastases to the Extraocular Muscles From Small Cell Lung Carcinoma
Crisóstomo, S; Cardigos, J; Hipólito Fernandes, D; Luís, ME; Neri Pires, G; Duarte, AF; Magriço Boavida, ABilateral orbital metastases restricted to the extraocular muscles (EOMs) are exceedingly rare. We report a case of bilateral extraocular muscle metastases from a small cell lung carcinoma and provide a review of the relevant literature. A 56-year-old smoker presented with proptosis, motility changes, and a relative afferent pupillary defect of the left eye, with a previous history of a small cell lung carcinom...
Choroidal Binarization Analysis: Clinical Application
Crisóstomo, S; Cardigos, J; Hipólito Fernandes, D; Luís, ME; Figueiredo, R; Moura-Coelho, N; Cunha, JP; Abegão Pinto, L; Tavares-Ferreira, JIntroduction: Image processing of optical coherence tomography scans through binarization techniques represent a non-invasive way to separately asses and measure choroidal components, in vivo. In this review, we systematically search the scientific literature regarding binarization studies published so far. Methods: A systematic research was conducted at PubMed database, including English literature articles fo...
Association Between Memory B-Cells and Clinical and Immunological Features of P...
Barcelos, F; Martins, C; Papoila, A; Geraldes, C; Cardigos, J; Nunes, G; Lopes, T; Alves, N; Vaz-Patto, J; Branco, J; Borrego, LMB-cells play a pivotal role in primary Sjögren's syndrome (pSS) pathogenesis. We aim to (1) evaluate the distribution of B-lymphocyte subpopulations in pSS and Sicca patients, (2) establish cut-off points that discriminate pSS from controls, (3) evaluate the association between memory B-cells and phenotypic features in pSS. We included 57 pSS patients, 68 Sicca and 24 healthy controls. Circulating B-cells were ...
A Morfologia Endotelial e a Espessura Central da Córnea em Idade Pediátrica
Cardigos, J; Neri, G; Crisóstomo, S; Paixão, A; Martins, M; Marques, M; Toscano, AIntrodução: O estudo morfológico e funcional do endotélio corneano é essencial para a criação de bases normativas de comparação, com utilidade na prática clínica e investigação científica. O objectivo deste estudo é a avaliação da morfologia endotelial e espessura central da córnea (ECC) em crianças saudáveis entre os 5 e os 15 anos, avaliando a sua variação segundo a idade. Métodos: Estudo de coorte transversa...
