Oncologic reconstructive surgery of the talus with structural allograft: Case report.

Introduction And Importance: Introduction and importance: Bone tumors of the foot constitute 3 % of all bone tumors, within these, the location in the talus constitutes between 8 and 23 % of bone tumors. Within the oncological management of these lesions, preservation surgery has had a great boom in the last 10 years, however, the use of massive structural allograft is not a conventional surgery and there is little literature on its use, which is why we consider important to document clinical cases.

Case Presentation: we document 2 clinical cases of bone tumor in the talus that were surgically managed with tumor resection plus reconstruction with total and partial talus allograft.

Proximal femur alloprosthesis in a pediatric patient with Ewing sarcoma: Case report.

Introduction And Importance: Ewing sarcoma is a primary malignant tumor of bone and, to a lesser extent, soft tissues. Within oncological management, surgery with extensive local control and reconstruction is the most accepted option, however, the size, extension of the tumor, the age of the patient and distant involvement can make this option difficult.

Case Presentation: We present a clinical case of a 3-year-old infant with Ewing sarcoma in the proximal femur, who was managed with wide resection of the tumor plus proximal humerus allograft, which acted as a proximal femur for 2 years and then presented joint failure due to what was done was the application of a cemented stem over the remnant of the allograft to save the hip.

Deep Learning Application to Detect Glaucoma with a Mixed Training Approach: Public Database and Expert-Labeled Glaucoma Population.

Introduction: Artificial intelligence has real potential for early identification of ocular diseases such as glaucoma. An important challenge is the requirement for large databases properly selected, which are not easily obtained. We used a relatively original strategy: a glaucoma recognition algorithm trained with fundus images from public databases and then tested and retrained with a carefully selected patient database.
