Using artificial intelligence to prioritize pathology samples: report of a test...
Rienda, Iván; Vale, João; Pinto, João; Polónia, António; Eloy, CatarinaThe digital transformation of pathology, through automation and computational tools, addresses current challenges in the field. This study evaluates Paige Pan Cancer, a novel artificial intelligence tool based on the Virchow foundation model, designed to flag invasive cancer in haematoxylin and eosin-stained slides from 16 primary tissue types. Using 62 cases from the Ipatimup Pathology Laboratory, we found the...
Computacional pathology: What’s new
Coelho, Daniel; Assunção, Teresa; Borrecho, Gonçalo; Geraldes, Mariana; Vinagre, Tiago; Ferreira, Inês; Ferreira, Ana; Fernandes, Ana IsabelThe term computacional pathology (CPath) has become a buzz-word among the digital pathology community. Adances in scanning systems, imaging technologies and storage devices are generating an ever-increasing volume of whole-slide images (WSI) acquired in clinical settings, which can be computacionally analyzed using artificial intelligence (AI), such as deep learning technologies, in a new área of development ca...
Algoritmos de inteligência artificial para diagnóstico do cancro da próstata
Pinho, Bia; Vale, João; Malhão, Fernanda; Silva, ReginaO cancro da próstata (CP) é o segundo tipo de cancro mais incidente nos homens. O diagnóstico histológico está sujeito à subjetividade e variabilidade interobservador pois baseia-se no reconhecimento visual de padrões morfológicos. A Patologia Digital e a aplicação de algoritmos de Inteligência Artificial (IA) às imagens digitais podem auxiliar os patologistas, reduzindo a subjetividade, permitindo um diagnósti...
Optimizing the management of thyroid specimens to efficiently generate whole sl...
Eloy, Catarina; Vale, João; Barros, Mariana; Oliveira, Diana; Mesquita, Morgana; Curado, Mónica; Pinto, João; Polónia, AntónioTransition from optical to digital observation requires an additional procedure in the pathology laboratory, the scanning of glass slides, leading to increased time and digital archive consumption. Thyroid surgical samples often carry the need to collect several tissue fragments that generate many slides to be scanned. This study evaluated the impact of using different inking colours for the surgical margin, se...
Biomarkers in whole slide images stained by: Hemtoxylin-Eosin: A groundbreaking...
Borrecho, Gonçalo; Curado, Mónica; Vale, João; Vinagre, Tiago; Geraldes, Mariana; Assunção, Teresa; Coelho, Daniel; Ferreira, Inês; Ferreira, AnaBiomarkers play a fundamental role in the diagnosis, prognosis and prediction of diseases. The study of biomarkers requires the performance of complementary diagnostic tests, which entails high costs and inevitably leads to an increase in response time, which could have a severe impact on the patient’s outcome. The digital transformation in Pathology Laboratories, accompanied by the wide implementation of slide...
Inking cell blocks improves scanner detection for diagnosis in pathology
Eloy, Catarina; Neves, Beatriz; Vale, João; Campelos, Sofia; Curado, Mónica; Polónia, AntónioCell blocks may be hard to be totally automatically detected by the scanner (ADS),generating incomplete whole slide images (WSIs), with areas that are not scanned,leading to possible false negative diagnosis. The aim of this study is to test if inkingthe cell blocks helps increasing ADS. Test 1: 15 cell blocks were sectioned, one halfinked black (1HB) and the other inked green (1HG). Each of the halves was indi...
Hind-Foot Synovial Sarcoma Treated With Wide Resection and Sural Fasciocutaneou...
Vale, João; Diniz, Sara; Campos Pereira, Eva; Cardoso, Pedro; Oliveira, VâniaSynovial sarcoma comprises about 5% to 10% of soft tissue sarcomas. Initial growth is often slow and a small circumscribed tumour may misleadingly appear to a benign lesion by clinical examination and imaging, occurring in up to 50% of cases. The modalities of treatment of foot malignant conditions depend on histological diagnosis and staging. A radical surgical procedure in the distal region of the lower limb ...
Impact of COVID-19 pandemic and national lockdown in an orthopaedic and traumat...
Ribau, Ana; Vale, João; Xará-Leite, Francisco; Rodrigues-Pinto, RicardoBackground: The coronavirus disease-2019 pandemic has forced health systems to undergo dynamic changes. This study aims to evaluate the impact of the pre-lockdown and of the lockdown period on the surgical activity of a Portuguese Orthopaedic and Traumatology Department and to compare it with the homologous period of 2019. Methods: The surgical activity between March 2 and May 2, 2020 and that of the homologous...
Isolated traumatic posterior dislocation of the radial head in an adult, a rare...
Fonte, Hélder; Rodrigues, Cláudia; Vale, João; Ramos, Joaquim; Costa e Castro, JoséIsolated radial head dislocations are rare in adults with only 23 cases published in 45 years. The diagnosis may be easily missed on radiographs and a CT-scan is often required. If managed promptly patient can restore normal range of motion and elbow function. Authors report a new case of a 67-year-old female presenting a posttraumatic isolated posterior dislocation of the radial head. Treatment consisted of cl...
A generative-oriented model-driven design environment for customizable video su...
Cardoso, Nuno; Rodrigues, Pedro; Vale, João; Garcia, Paulo; Cardoso, Paulo; Monteiro, João L.; Cabral, Jorge; Mendes, José A.; Ekpanyapong, MongkolTo tackle the growing complexity and huge demand for tailored domestic video surveillance systems along with a high demanding time-to-market expectation, engineers at IVV Automação, LDAa are exploiting video surveillance domain as families of systems that can be developed following a pay-as-you-go fashion rather than developing an ex-nihilo new product. Several and different new functionalities are required for...
