The healing process of vertebral body fracture in Wistar rats
Moura, Diogo Lino; Casal, Diogo; Alves, Sara; Almeida, Rui; PAIS, DIOGO; Casanova, José; Bernardes, AntónioPublisher Copyright: Copyright © 2025 AME Publishing Company. All rights reserved.; Background: Although recognition of avascular necrosis of the vertebral body in post-traumatic cases has increased, it remains underdiagnosed and is one of the most unpredictable and challenging complications in spinal trauma. Vertebral arterial supply may play a key role in fracture healing, yet this remains unproven and is not...
Functional shoulder girdle reconstruction in paediatric desmoid tumour
Albuquerque, Maria; Constantino, Cláudia; Martins, Pedro; Casal, DiogoPublisher Copyright: © The Author(s) 2025. Published by Oxford University Press and JSCR Publishing Ltd.; Desmoid tumours are rare fibroblastic neoplasms that, although benign, may be locally aggressive, invasive, and disabling. In children with Gardner syndrome, they typically arise in the abdominal wall, whereas scapular involvement is uncommon and surgically challenging because of the risk of scapular wingin...
L1 vertebral body replacement using 3D-printed polylactic acid bioimplants
Moura, Diogo Lino; Casal, Diogo; Reis, Rodrigo; Gonçalves, Luís; Alves, Sara; Pinto, Dora; Novo, Manuela; Fontinha, Guilherme; Almeida, RuiBackground: The vertebral body plays a crucial role in supporting compressive loads and maintaining spinal biomechanics. An ideal biomaterial for total vertebral body replacement should combine biological and mechanical properties, yet no current material fulfills all criteria. This pilot study explores the use of a novel three-dimensional (3D)-printed porous polylactic acid (PLA) implant for total L1 vertebral...
Impact of Infrasound Exposure and Streptozotocin-Induced Glucose Intolerance on...
Zagalo, Luísa; Pereira, Gonçalo; Casal, Diogo; Gonçalves, Luísa L; Zagalo, Carlos; Oliveira, Maria João; Oliveira, Pedro; Brito, José A AThe elemental composition of chemical elements can vary between healthy and diseased tissues, providing essential insights into metabolic processes in physiological and diseased states. This study aimed to evaluate the calcium (Ca) and phosphorus (P) levels in the bones of rats with/without streptozotocin-induced diabetes and/or exposure to infrasound. X-ray fluorescence spectroscopy was used to determine the c...

Ensino de Anatomia em Colaboração com a Radiologia no Mestrado Integrado de Med...
Bilhim, Tiago; Casal, Diogo; Mateus Marques, Rui; Pais, DiogoOs principais desafios ao ensino de anatomia e radiologia no mestrado integrado de medicina (MIM) prendem-se com o tempo limitado e o enorme volume de informação. Para fazer face as estas limitações, as reformas do MIM levaram a que o ensino de anatomia e radiologia fosse fundido em muitas faculdades de medicina. Na NOVA medical school, o ensino de anatomia clínica e radiológica foi estruturado numa unidade cur...

Case Report: Dermatofibrosarcoma Protuberans of the Foot: What Steps Can We Take?
Matias, Miguel; Veríssimo, Miguel; Barbosa, Raquel; Casal, DiogoIntroduction and importance: Dermatofibrosarcoma protuberans (DFSP) is a rare soft tissue sarcoma affects mainly the trunk and proximal limbs. Clinically, it typically presents as an asymptomatic plaque or nodular-like lesion that progresses slowly before entering a rapid growth phase. DFSP exhibits a low potential for metastasis, mainly in cases where fibrosarcomatous transformation occurs, but it has a high r...
Review of Piezoelectrical Materials Potentially Useful for Peripheral Nerve Repair
Casal, Diogo; Casimiro, Maria; Ferreira, Luís; Leal, João; Rodrigues, Gabriela; Lopes, Raquel; Moura, Diogo; Gonçalves, Luís; Lago, João; Pais, DiogoIt has increasingly been recognized that electrical currents play a pivotal role in cell migration and tissue repair, in a process named “galvanotaxis”. In this review, we summarize the current evidence supporting the potential benefits of electric stimulation (ES) in the physiology of peripheral nerve repair (PNR). Moreover, we discuss the potential of piezoelectric materials in this context. The use of these ...
Retrospective Study of 114 Free Flaps for Head and Neck Oncological Reconstruct...
Silva, Andreia; Caixeirinho, Patrícia; Vilares, Miguel; Semedo, Carina; Martins, Mariluz; Zagalo, Carlos; Casal, DiogoIntroduction: The Portuguese experience in microsurgical reconstruction of the head and neck after oncological surgery is scantly described. The primary aim of this study was to characterize the use of microvascular reconstruction after head and neck tumor resection in a Portuguese tertiary oncological centerMaterial and Methods: The authors retrospectively evaluated 114 microvascular free flap procedures perfo...
