Skin deformation analysis for pre-operative planning of DIEAP flap reconstructi...
Timóteo, Rafaela; Pinto, David; Martinho, Marta; Gouveia, Pedro; Lopes, Daniel Simões; Mavioso, Carlos; Cardoso, Maria JoãoDeep inferior epigastric artery perforator (DIEAP) flap reconstruction surgeries can potentially benefit from augmented reality (AR) in the context of surgery planning and outcomes improvement. Although three-dimensional (3D) models help visualize and map the perforators, the anchorage of the models to the patient's body during surgery does not consider eventual skin deformation from the moment of computed tomo...
3D breast volume estimation
Gouveia, Pedro; Oliveira, Hélder P.; Monteiro, João P.; Teixeira, João F.; Silva, Nuno L.; Pinto, David; Mavioso, Carlos; Anacleto, JoãoIntroduction: Breast volume estimation is considered crucial for breast cancer surgery planning. A single, easy, and reproducible method to estimate breast volume is not available. This study aims to evaluate, in patients proposed for mastectomy, the accuracy of the calculation of breast volume from a low-cost 3D surface scan (Microsoft Kinect) compared to the breast MRI and water displacement technique. Materi...
Breast cancer surgery with augmented reality
Gouveia, Pedro; Costa, Joana; Morgado, Pedro; Kates, Ronald; Pinto, David; Mavioso, Carlos; Anacleto, João; Martinho, Marta; Lopes, Daniel SimõesIntroduction: Innovations in 3D spatial technology and augmented reality imaging driven by digital high-tech industrial science have accelerated experimental advances in breast cancer imaging and the development of medical procedures aimed to reduce invasiveness. Presentation of case: A 57-year-old post-menopausal woman presented with screen-detected left-sided breast cancer. After undergoing all staging and pr...
Presentation of "ShappList"
Pinto, David; Chuva, Henrique; Correia, Pedro; Machado, RicardoShapplist was created with the purpose of providing customers a simple and intuitive way to create shopping lists, while having the ability to share these with friends, co-workers or family members through an invite system. The available products are of equal importance, as these are collected from the main supermarkets in the country – Pingo Doce, Continente and Jumbo – allowing users to check which supermarke...

Composição e abundância de macrófitas num troço do rio Ovelha
Andrade, Alexandre; Azevedo, Francisca; Bessa, Catarina; Brás, Maria João; Carneiro, Tomás; Cerqueira, Maria Margarida; Geraldes, Inês; Leal, SofiaAs macrófitas fluviais são um grupo relevante para a avaliação ecológica dos rios. Numa amostragem realizada num troço de 100 m do rio Ovelha, localizado a 217 m de altitude, na freguesia de Fornos, Marco de Canaveses, estudou-se a abundância, composição e distribuição das macrófitas. Verificou-se que o troço estudado é pobre em macrófitas, apresentando uma riqueza específica baixa, o que poderá estar relaciona...
Metastização gástrica e entérica de Carcinoma Lobular Invasivo da Mama
Pinto, David; Morgado, Carolina; Foreid, Susan; Vera-Cruz, Soraya; Coimbra, João; Andrade, DavidO carcinoma lobular invasivo (CLI) representa 5-15% dos casos de cancro invasivo da mama, diferindo do carcinoma ductal invasivo (CDI), o tumor invasivo mais frequente da mama, quer na forma de apresentação clínica, quer nos aspectos imagiológicos e histológicos, assim como no padrão de metastização. O objectivo deste artigo passa pelo relato clínico de um padrão atípico de metastização de cancro da mama. Mulhe...
Prevalence and determinants of atypical presentation of acute coronary syndrome.
Pinto, David; Lunet, Nuno; Azevedo, AnaKnowledge of the characteristics of patients with atypical presentation of acute coronary syndromes may contribute to increased sensitivity in diagnosis in a given population. The purpose of this study is to quantify the prevalence of atypical presentation, to identify its determinants, and to describe the presenting symptoms in cases of acute coronary syndrome at the emergency department of Hospital São João, ...
