NSAID analgesics may confound models that require inflammation to mimic disease development in humans. This effect presents a challenge for veterinary staff and investigators, because surgery is often necessary to create mouse models of disease and NSAID are first-line analgesics used to treat postoperative pain. We evaluated robenacoxib, a NSAID highly selective for cyclooxygenase 2, in a carrageenan paw edema (CPE) assay and surgical model of venous thrombosis (VT). We generated a mouse-specific dose-response curve by using the CPE assay for robenacoxib doses of 3...

A 20-month-old female spayed Staffordshire Terrier (22.3 kg) presented to the Orthopedic Surgery Service at North Carolina State University Veterinary Teaching Hospital for evaluation of a 6-week history of toe-touching to nonweight-bearing lameness in the right hind limb. Radiographs of the right stifle revealed a multiloculated lytic lesion of the distal femur, with a large open lytic zone centrally, numerous osseous septations peripherally, and focal areas of cortical thinning and loss. An aspirate of the right distal femoral lesion yielded mildly cloudy serosanguineous fluid...

Case summary: A 10-year-old spayed female American Shorthair cat underwent renal transplantation due to worsening chronic kidney disease secondary to polycystic kidney disease. During transplantation, the right kidney grossly appeared to be more diseased than the left and was firmly adhered to the surrounding tissues. An intraoperative fine-needle aspirate of the right native kidney revealed inflammatory cells but no evidence of neoplasia. To create space for the allograft, a right nephrectomy was performed...

The objective of this study was to evaluate the influence of the dog's long-term separation from its owner in the novel environment on the occurrence of psychogenic and oxidative stress. Group I dogs (n=9) were brought to the veterinary clinic and stayed in a kennel room for 12 hr before the surgery, and group II dogs (n=9) - for 10 min before the surgery. Physiological parameters (heart rate (HR) (beats/min) and respiratory rate (fR ) (breaths/min)) were measured and blood sampling was done 12 hr before the surgery (T0) for group I dogs and 10 min before the surgery (T1) for both groups dogs...

Case summary: A 6-month-old female cat with a history of chronic regurgitation presented with weight loss. CT angiography (CTA) showed severe constriction of the oesophagus due to an aberrant right subclavian artery and Kommerell's diverticulum. The cat was surgically treated and remained clinically normal. More than 1 year after surgery, the general condition of the cat was stable and body weight had increased. Relevance and novel information: This case report describes the clinical findings and surgical management of a cat diagnosed with severe oesophageal constriction caused by an aberrant right subclavian artery with Kommerell's diverticulum (markedly dilated origin of the aberrant right subclavian artery), which are rare vascular anomalies in veterinary medicine and specifically in cats...

Bone sequestration is relatively unknown in New-world camelids in Germany and is frequently wrongly addressed as neoplasia by veterinary practitioners. This clinical case report describes diagnosis and treatment for bone sequestration in alpacas based on 12 cases. The main symptom of the presented alpacas was moderate to severe lameness in one limb. Some of the patients had been treated with nonsteroidal anti-inflammatory drugs by the referring veterinarian. In eight alpacas, palpation of the swelling in the affected leg was painful and in five animals, exudation was observed...

One of the major challenges in surgical oncology is the intraoperative discrimination of tumoural versus healthy tissue. Until today, surgeons rely on visual inspection and palpation to define the tumoural margins during surgery and, unfortunately, for various cancer types, the local recurrence rate thus remains unacceptably high. Near-infrared (NIR) fluorescence imaging is an optical imaging technique that can provide real-time preoperative and intraoperative information after administration of a fluorescent probe that emits NIR light once exposed to a NIR light source...

Neuroanatomy can be challenging to both teach and learn within the undergraduate veterinary medicine and surgery curriculum. Traditional techniques have been used for many years, but there has now been a progression to move towards alternative digital models and interactive 3D models to engage the learner. However, digital innovations in the curriculum have typically involved the medical curriculum rather than the veterinary curriculum. Therefore, we aimed to create a simple workflow methodology to highlight the simplicity there is in creating a mobile augmented reality application of basic canine head anatomy...

The earliest cranial surgery (trepanation) has been attested since the Mesolithic period. The meaning of such a practice remains elusive but it is evident that, even in prehistoric times, humans from this period and from the Neolithic period had already achieved a high degree of mastery of surgical techniques practiced on bones. How such mastery was acquired in prehistoric societies remains an open question. The analysis of an almost complete cow cranium found in the Neolithic site of Champ-Durand (France) (3400-3000 BC) presenting a hole in the right frontal bone reveals that this cranium underwent cranial surgery using the same techniques as those used on human crania...

Here we present a 32-y-old rhesus macaque (Macaca mulatta) with a large recurrent ventral incisional hernia. The initial surgery included midline celiotomy for treatment of endometriosis, in which the animal developed a hernia that was repaired with interposition of mesh. Hernia recurrence at 1 y resulted in a defect measuring 7 × 13 cm, with loss of abdominal domain. Skin breakdown was noted with areas of exposed mesh through the skin with associated acute on chronic infection. Clinically, the animal was lethargic, not eating, and failing to thrive...

Spaceflight results in bone loss like that associated with osteoporosis or decreased weight-bearing (for example, high-energy trauma such as explosive injuries and automobile accidents). Thus, the unique spaceflight laboratory on the International Space Station presents the opportunity to test bone healing agents during weightlessness. We are collaborating with NASA and the US Army to study bone healing in spaceflight. Given the unique constraints of spaceflight, study design optimization was required. Male mice were selected primarily because their femur is larger than females', allowing for more reproducible surgical outcomes...

OBJECTIVES: To describe a technique using bipolar electrosurgical forceps for haemostasis during open ovariectomy of bitches and queens and for castration of dogs and to determine whether these forceps reduced surgical time compared to ligation with suture. MATERIALS AND METHODS: Bipolar electrosurgical forceps were used for haemostasis in 3744 open surgeries including ovariectomies in bitches (n=1406) and queens (n=859) and castrations in dogs (n=1335). The forceps were also used to assist with ovariohysterectomy in bitches (n=89) and queens (n=55)...

Despite the existence of the American College of Veterinary Pathology guidelines for tumour biopsy specimens, anecdotally the authors' have seen inconsistency of reporting of information on the pathology report for canine soft tissue sarcomas (STSs). If crucial aspects are not reported this can result in slower or impeded patient care. This retrospective study evaluated 255 STS histopathology reports submitted from across the United States. Reports were evaluated by a single observer to assess for information contained in 5 main categories: patient history and signalment, gross and microscopic description, grading, histologic margins and the comments section...

Toxocara canis is the helminth causing Toxocariasis, a parasitic disease with medical and veterinary implications. Their final host are members of the family Canidae and as paratenic hosts, most of the mammals are sensitive (man, rat, mouse, among others). It has been reported that a pituitary hormone, prolactin, it is responsible for reactivation and migration of larvae to the uterus and mammary gland during the last third of gestation in bitches. In addition, this hormone has been shown to play an important role in the regulation of the immune response...
