Osseointegration assessment of multi‐material Ti6Al4V‐β TCP implants: an experi...
Costa, Mafalda M.; Miranda, Alice; Bartolomeu, Flávio; Carvalho, Óscar; Matos, Sérgio; Silva, Filipe Samuel; Miranda, GeorginaIn the present study, mono- and multi-material laser textured Ti6Al4V implants are manufactured and characterized in vivo to explore their applicability in orthopedic implants. Laser surface texturing is used for manufacturing grooved Ti6Al4V implants while a pressure-assisted sintering technique is employed to impregnate beta-tricalcium phosphate into grooves for an improved bioactivity. After implantation int...
Serotonin regulates prostate growth through androgen receptor modulation
Dias, Emanuel Carvalho; Miranda, Alice; Martinho, Olga; Mota, Paulo; Costa, Ângela Margarida Amorim; Nogueira-Silva, Cristina; Moura, Rute S.Serotonin regulates prostate growth through androgen receptor modulation; Aging and testosterone almost inexorably cause benign prostatic hyperplasia (BPH) in Human males. However, etiology of BPH is largely unknown. Serotonin (5-HT) is produced by neuroendocrine prostatic cells and presents in high concentration in normal prostatic transition zone, but its function in prostate physiology is unknown. Previous e...
Resection of sentinel lymph nodes by an extraperitoneal minilaparoscopic approa...
Ferreira, Hélder; Silva, Cristina Isabel Nogueira; Miranda, Alice; Correia-Pinto, JorgeBackground. The sentinel lymph node (SLN) concept might minimize surgical aggressiveness in cervical and endometrial malignancies. The aim of the study was to test the feasibility and reliability of minilaparoscopic extraperitoneal SLN excision after indocyanine green (ICG) cervical injection using a high-definition near infrared (NIR) imaging system in an in vivo porcine model. The same procedure was performed...
Sparing internal thoracic vessels in thoracoscopic or submuscular correction of...
Pinheiro, Ruben Lamas; Mitzman, Francesca; Miranda, Alice; Coelho, Tiago Henriques; Costa, José Estevão; Correia-Pinto, JorgeSupplementary data to this article can be found online at http://dx. doi.org/10.1016/j.jpedsurg.2015.07.023.; Background: External compression is used for pectus carinatum (PC) treatment, but many patients are noncompliant. Costal cartilage resection (CCR) has been described as an alternative, but these approaches sacrifice the internal thoracic arteries (ITA). We aim to assess the feasibility of CCR sparing IT...
IMMUNE RECONSTITUTION INFLAMMATORY SYNDROME: A POTENTIAL PITFALL IN THE MANAGEM...
Ladeira de Oliveira, Felipe; Sírio, Deborah Maria Brito; Cerutti, Gisele; de Natividade, Natalia Barreiros; de Menezes, Vinicius Martins; Miranda, AliceThe variety of immune reconstitution inflammatory syndrome’s (IRIS) clinical presentations makes this syndrome a challenge, in that it is difficult to manage opportunistic infections and other serious clinical conditions related to the manifestation of this syndrome. The relevance of immune reconstitution inflammatory syndrome – associated with Kaposi sarcoma (IRIS-KS) after initiation of highly active antiretr...
Hybrid endoscopic thymectomy : combined transesophageal and transthoracic appro...
Miranda, Alice; Rolanda, Carla; Pinto, Jorge Correia; Pinto, João Moreira; Ferreira, AníbalBACKGROUND: Video-assisted thoracoscopic surgery thymectomy has been used in the treatment of Myastenia Gravis and thymomas (coexisting or not). In natural orifice transluminal endoscopic surgery, new approaches to the thorax are emerging as alternatives to the classic transthoracic endoscopic surgery. The aim of this study was to assess the feasibility and reliability of hybrid endoscopic thymectomy (HET) usin...
Minilaparoscopy and sentinel lymph node in uterine cancer
Ferreira, Hélder; Silva, Cristina Isabel Nogueira; Miranda, Alice; Correia-Pinto, JorgeCRSLS MIS Case Reports from SLS.org.; Background: The sentinel lymph node (SLN) concept might minimize surgical aggressiveness in gynecological oncology, namely in cervical and endometrial malignancies. Therefore, we assessed the feasibility of SLN identification, dissection, and harvesting by using minilaparoscopic surgical instruments in an animal model. We compared the minilaparoscopic approach, which is kno...
Transthoracic single port with peroral assistance : an animal experiment to ass...
Coelho, Tiago Henriques; Soares, T. R.; Miranda, Alice; Pinto, João Moreira; Pinto, Jorge CorreiaProva tipográfica.; Thoracoscopic repair of esophageal atresia has becoming the gold standard in many centers since it allows a better cosmetic result and avoids the musculoskeletal sequelae of a thoracotomy. Natural Orifices Transluminal Endocopic Surgery (NOTES) is a new surgical paradigm and its human application was already started in some procedures. In the present study, we explore the feasibility to perf...
Transesophageal pulmonary lobectomy with single transthoracic port assistance: ...
Pinto, João Moreira; Ferreira, Aníbal; Miranda, Alice; Rolanda, Carla; Pinto, Jorge CorreiaBACKGROUND AND STUDY AIMS: Thoracoscopic pulmonary lobectomy is being performed in an increasing number of patients. The aims of the current study were to assess natural orifice transluminal endoscopic surgery (NOTES) as an alternative to transthoracic endoscopic surgery, and to test the feasibility of peroral transesophageal right upper pulmonary lobectomy with the assistance of a single transthoracic trocar. ...
Epidemiological survey of dermatophytosis in meat rabbits with alopecia in Port...
Moreira, Fernando; Miranda, Alice; Coelho, Adosinda; Monteiro, José Manuel; Coelho, Ana; Pinto, Maria; Matos, ManuelaAn epidemiological dermatophytosis survey was carried out in farmed rabbits with alopecia in Northern and Central Portugal. Between August and October 2008, samples from suspected clinical cases of alopecia in meat rabbits on industrial farms were collected and cultured by conventional methods. Effects on the prevalence of several variables, such as breed, age, month of sample collection, configuration of the l...
