“…95,100 These neoplasms are commonly observed in numerous avian species. 1,2,[95][96][97][98][99][100][101][102][103][104][105][106][107][108] For parrots, our findings were in agreement with previous work, with 4 cases of SCC diagnosed in the uropygial gland and 1 as a dermal mass on the wing. In chickens, SCC occurs infrequently, but there have been reports of dermal lesions on the legs with a benign biological behavior that spontaneously resolve, 19 malignant generalized skin ulceration (avian keratoacanthoma), 109,110 and lesions in the oropharynx and upper gastrointestinal tract.…”

Over a 3.5-year period, tissue samples from 141 companion and aviary birds with clinically suspected, naturally occurring solid neoplasms were collected via surgical biopsy (n = 53) or at necropsy examination (n = 88) from a population of birds presenting to an avian veterinary clinic in Melbourne, Australia. Neoplastic processes were identified in 73.7% (n = 104) of samples, with 83.7% (n = 87) being interpreted as malignant neoplasia and 16.3% (n = 17) being interpreted as benign neoplasia. The overall estimated prevalence of neoplasia in the study population (n = 5125) was 2.45% (95% confidence interval, 2–2.97%). The gastrointestinal and reproductive tracts were the most commonly affected systems. The most common presenting signs were nonspecific and included lethargy, coelomic distension, and inappetence. In 59 cases, fine-needle aspirates (FNAs) and impression smears were also obtained and evaluated cytologically. The accuracy of cytology for detecting neoplasia in birds and for determining whether a neoplastic process was benign or malignant was assessed by using histopathology as the “gold standard.” There was complete agreement between the cytological and histopathological diagnoses in 72.8% (43/59) of cases. Cytology correctly identified 87.5% of these cases (35/40) as malignant neoplasms and 55.6% (5/9) as benign processes. There was no significant difference between the use of cytology and histopathology for the detection of malignant neoplasia in birds (P = 0.185). The accuracies of FNAs and impression smears for examining avian tumors were also compared. Overall, the best cell preservation was obtained by performing impression smears from tissues, with 62.2% (n = 28) returning high cellularity for cytological examination, compared to 53.8% (n = 14) when samples were obtained by FNA. This study provides an overview of the types and prevalence of neoplasms in a captive bird population from Australia, correlates physical examination findings with tumor types, and provides evidence that cytology is a reliable preliminary diagnostic tool for detecting neoplasia in birds.

“…During the observation of the bird in its natural environment, no strange behaviors were observed, which suggests the acceptance by the bird of the 3D printed AFO as part of its own body. Xie et al achieved a similar result in a study on the use of a 3D printed prosthesis for a Great Hornbill (Xie et al, 2019). These positive results suggest great potential in applying these technologies to the treatment of other diseases and malformations in both farmed, domestic, and wild animals.…”

Purpose Chicken orthoses that cover the ankle joint area are not commercially available. Therefore, the main purpose of this study is to fabricate a customised temporary Ankle–Foot Orthosis (AFO) for a chicken with a twisted ankle using computer-aided design (CAD) and three-dimensional (3D) printing. The secondary objective of the paper is to present the specific application of Additive Manufacturing (AM) in veterinary medicine. Design/methodology/approach The design process was based on multiple sketches, photos and measurements that were provided by the owner of the animal. The 3D model of the orthosis was made with Autodesk Fusion 360, while the prototype was fabricated using fused deposition modelling (FDM). Evaluation of the AFO was performed using the finite element method. Findings The work resulted in a functional 3D printed AFO for chicken. It was found that the orthosis made with AM provides satisfactory stiffen and a good fit. It was concluded that AM is suitable for custom bird AFO fabrication and, in some respects, is superior to traditional manufacturing methods. It was also concluded that the presented procedure can be applied in other veterinary cases and to other animal species and other parts of their body. AM provides veterinary with a powerful tool for the production of well-fitted and durable orthoses for animals. Research limitations/implications The study does not include the chicken's opinion on the comfort or fit of the manufactured AFO due to communication issues. Evaluation of the final prototype was done by the researchers and the animal owner. Originality/value No evidence was found in the literature on the use of AM for chicken orthosis, so this study is the first to describe such an application of AM. In addition, the study demonstrates the value of AM in veterinary medicine, especially in the production of devices such as orthoses.

Previous studies have demonstrated evidence that three‐dimensional (3D) visualization techniques can be helpful as learning tools. This prospective randomized control study was designed to test the hypothesis that 3D learning tools would have improved translation into interpreting normal and abnormal canine abdominal radiographic images over traditional learning tools. Sagittal and dorsal plane 3D image scenes were created from CT scans, with canine abdominal organs labeled using virtual reality and 3D visualization software tools. Eighty students from the first‐ and second‐year veterinary classes at a single institution participated in the study. The control group studied canine abdominal anatomy from a textbook and the experimental group studied canine abdominal anatomy using the 3D learning tools for a set time. Each participant then took a three‐part written examination to assess their learning for the following categories: 3D anatomy organ identification, radiographic anatomy organ identification of normal structures and radiographic anatomy organ identification of abnormal structures. All participants were also asked to identify the sex of the test patient from the 3D study. Participants from the experimental group performed statistically better than participants in the control group for all parts of the examination, with the exception of normal radiographic anatomy.
