The aim of this project was to develop a detailed, accessible set of reference images of the normal radiographic anatomy of the ovine digit up to and including the metacarpo/metatatarsophalangeal joints. The lower front and hind limbs of 5 Lleyn ewes were radiographed using portable radiography equipment, a digital image processer and standard projections. Twenty images, illustrating the normal radiographic anatomy of the limb were selected, labelled and presented along with a detailed description and corresponding images of the bony skeleton. These images are aimed to be of assistance to veterinary surgeons, veterinary students and veterinary researchers by enabling understanding of the normal anatomy of the ovine lower limb, and allowing comparison with the abnormal.

Background Detection and segmentation of lung tumors on CT scans are critical for monitoring cancer progression, evaluating treatment responses, and planning radiation therapy; however, manual delineation is labor-intensive and subject to physician variability. Purpose To develop and evaluate an ensemble deep learning model for automating identification and segmentation of lung tumors on CT scans. Materials and Methods A retrospective study was conducted between July 2019 and November 2024 using a large dataset of CT simulation scans and clinical lung tumor segmentations from radiotherapy plans.

Background: Hemifacial microsomia (HFM) presentation includes gross distorted ramus, malposition temporomandibular joint, small glenoid fossa, distorted condyle and notch, malformed orbit, cupping ear or absent external ear, and facial nerve palsy. HFM is the second most prevalent congenital deformity of the face, with little literature from the South African population. This retrospective study elucidated the demographic characteristics and clinical presentations of HFM patients in a select South African population and compared it to the literature.

Objectives: Well-differentiated neuroendocrine tumors (NET) are highly vascular tumors characterized by their expression of vascular endothelial growth factor (VEGF). This trial investigated the activity of ramucirumab, a monoclonal antibody that targets VEGF receptor-2 (VEGFR-2) and inhibits activity of VEGF, in combination with somatostatin analog therapy in patients (pts) with advanced extra-pancreatic NET.
Methods: We conducted a single-arm phase II trial enrolling pts with advanced, progressive extra-pancreatic NET.

Radicular cysts are one of the most common cysts of inflammatory origin involving the maxillofacial region that arise from the remnants of Herwig's epithelial root sheath. These are often diagnosed as incidental findings on radiographs, which are seldom symptomatic and are slowly progressive. Decompression could be used as a conservative treatment approach for the management of large radicular cysts in children to have satisfactory healing and minimum damage to adjacent vital structures, simultaneously allowing the eruption of succedaneous tooth.

Aims: Bone preservation is a requirement for long-term stability of dental prostheses, which is all the more important in the posterior mandible, given the particular challenges these areas pose to prosthetic treatment. The objective was to investigate the implications of different prostheses on the atrophy of posterior alveolar bone after tooth loss.
Materials And Methods: A total of 457 treatment cases were retrieved from the medical documentation and information network.
