Clinical findings and treatment Five cats had presented with injuries associated with road traffic accidents. These included three cats with abdominal hernias that required surgical management. At a median of 15 days after the accident, cats represented with lethargy, the presence of an abdominal mass or with lower urinary tract symptoms and in all cats contrast diagnostic imaging showed proximal unilateral TUR with associated para-ureteral urinoma. Four cats received subcutaneous ureteral bypass (SUB) device placement and one had ureteral anastomosis over a stent. Unilateral cyst-like retroperitoneal fluid consistent with para-ureteral urinoma was observed in all cats and a diffuse retroperitoneal haematoma was noticed in four cats. No immediate major complications occurred, and all cats had post-operative serum creatinine concentration within the reference interval. The cat that had received a ureteral stent subsequently required placement of a SUB following stent encrustation 15 months after surgery. Median follow-up time was 34 (min 28, max 58) months and renal function was normal in all cats at the last follow-up. Clinical relevance Urinary diversion procedures provided long-term stable renal function following proximal TUR in these five cats. Delayed, subtle non-specific clinical signs subsequent to high-energy blunt trauma causing abdominal hernia and associated diffuse retroperitoneal haematoma, should raise suspicion of TUR.

Fetal maceration is commonly seen in domestic species but rarely in the mare (Burns and Card 1998; Imani and Vosough 2018; McNaughten and Wallace 2019). Depending on the cause of in utero fetal death, the outcome may be abortion, maceration or mummification. Abortion (pregnancy loss between 35 and 330 days of gestation) occurs in 7–14.2% of mares (Sanderson and Allen 1987; Morris and Allen 2002). A small study conducted in the Waikato region of New Zealand recorded a pregnancy loss of 3% between day 42 of gestation and term (Hanlon et al. 2012). Mummification occurs when endocrine support to maintain the pregnancy is present. When endocrine support is lost, abortion (fetus is expelled) or maceration (fetus is retained) occurs. Failure to expel the dead fetus can be caused by uterine inertia, fetal malpositioning, inadequate cervical dilation or other pathological processes (Vézina et al. 1975). Surprisingly, and unlike retention of fetal membranes, uterine retention of a macerated fetus rarely causes systemic illness in the mare despite the presence of bacteria and purulent material. It has been proposed that the lack of systemic illness is due to the quick healing of the endometrium after placental separation, which prevents the absorption of toxic material and bacteria into the mare’s systemic circulation (Burns and Card 1998). Despite this, fetal bones may embed in the uterine wall, which can increase leakage of toxins into the bloodstream, causing a serious health risk (Imani and Vosough 2018). Here we describe a further case of fetal maceration in a mare to add to the available information on the clinical presentation and treatment of this unusual condition. A 14-year-old maiden, pregnant Stationbred mare in a remote region of New Zealand was presented with purulent vulvar discharge at 276 days since the last service date (LSD). Upon clinical examination, her vital parameters were within normal limits and examination of the external genitalia revealed no mammary gland development, normal perineal conformation and a moderate amount of purulent discharge at the ventral aspect of the vulva and on her tail. With a recommendation to bring the mare to a nearby facility with stocks where vaginal and rectal examination could be conducted safely, the mare was started on 12 mg/kg procaine penicillin (Ilium; Troy Laboratories Pty Ltd., Glendenning, Australia) I/M twice daily for 3 days and 2 mg/kg phenylbutazone (Caledonian Holdings, Auckland, NZ) orally twice daily for 3 days. Once the course of procaine penicillin was completed, the mare was continued on 3 g trimethoprim and 15 g sulfadimidine (Trimsulp powder; PhoenixPharm, Auckland, NZ) orally twice daily for 20 days. Ten days later transrectal examination was performed.

Quain","doi":"10.1080/00480169.2022.2105804","DOIUrl":"https://doi.org/10.1080/00480169.2022.2105804","url":null,"abstract":"With the rise of medical humanities, narrative medicine is becoming established in the human medical field, but there has been scant literature on narrative veterinary medicine. In this book, Karen Fine, a holistic, integrative practitioner, argues that narrative veterinary medicine will not only improve communication with clients, but also the care of veterinary patients and the wellbeing of veterinary team members. The first section provides an overview of narrative medicine, drawing primarily on medical literature to explain the emergence and conceptual basis of this field. In short, in veterinary practice, the client presents a patient or patients, and brings to the consultation a particular narrative. The client narrative yields insights into the client’s world view, which impacts the nature of the human-animal relationship, the decisions made on behalf of that animal, who they trust with the animal’s care, their expectations and “problems in parantheses” (deeper concerns that clients may struggle to articulate). With the veterinary team, a new narrative (including a plan) is co-created with the client. Fine explains how the stories we tell ourselves can impact our own perceptions and approaches to clients, and even our wellbeing. I was reminded of the work of Alf Wight, better known by his pen-name James Herriot. According to the biography written by his son Jim, Wight struggled with mental illness and often worked in difficult circumstances. Were Herriot’s stories an attempt to reframe his work and professional identity? The second section is structured around the veterinary consultation, including narratives of veterinary team members, obtaining a history, making a plan and recording the narrative. To paraphrase Rachel Naomi Remen, veterinarians cure with their expertise but heal with their experience and attention. The third section highlights issues Fine identifies as “unique” to the veterinary profession, including euthanasia, while the fourth focuses on the stories of veterinary team members. It introduces tools for reflective practice, including parallel charts (the story of the patient that isn’t included in medical records, but enables the clinician to develop their own narrative), and personal loss timelines (documentation of our own losses, and how these may inform our interaction with clients and patients). It incorporates narrative case studies throughout. Fine claims that burnout can be decreased by emphasising the unique stories of patients and clients rather than just focusing on diagnosis and treatment, while compassion fatigue can be reduced through reflective practice, and narrative boundary-setting. Whether and how this is the case remains to be seen, as there is a dearth of research in this field. It may be that narrative veterinary medicine reduces burnout and compassion fatigue by increasing engagement and interest. Given concerns about the wellbeing of veterinary team members, it is important that such questions are ","PeriodicalId":19322,"journal":{"name":"New Zealand veterinary journal","volume":"70 1","pages":"358 - 358"},"PeriodicalIF":1.4,"publicationDate":"2022-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46772807","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pain may be inevitable, but suffering is optional. Our ubiquitous negativity bias may have many in caregiving roles around the world focused on the negative impacts of compassion fatigue syndrome and/or of burnout in the workplace, particularly over the last 2.5 years since the COVID-19 pandemic impacted every aspect of our lives. However, do you know about compassion satisfaction or about eudaimonia? Keep reading. Veterinary professionals are some of the most intellectually curious, generous, and intuitively caring individuals. Choosing a profession with rigorous and stressful admission criteria and training to then focus their life’s work on caring for non-human species’ health and well-being demonstrates a commitment to compassionate community service. However, the majority of veterinary caregivers would admit that the community they feel compassion for and wish to focus their healing energy on is the veterinary patient, not necessarily the inevitable humans that come with the equation. Herein lies the conundrum: the emotional, physical, and psychological challenges that come with working as a veterinary caregiver are compounded by these necessary human interactions. Preparation and strategies to skilfully navigate these interactions have been historically sparse, but fortunately are growing in curricula, in training programmes, and through professional literature and resource sharing. There is a psychosocial concept that when utilised can support self-efficacy of caregivers during difficult emotional and psychological circumstances: “Name it to tame it.” The human medical community has been actively exploring and researching the myriad of caregiving challenges and potential impacts on caregivers for over 40 years. It is understood that just as the wellbeing of individuals and teams may be compromised by detrimental work factors, so may be the quality of patient care and professional fulfilment for medical professionals. Many of the same work-related concerns such as moral distress, secondary traumatic stress, compassion fatigue, and caregiver burnout experienced by medical workers are recognised in veterinary professionals as well. However, it is only in the last 10 years that the awareness and subsequent conversations that “name” these concerns are being investigated as they pertain to veterinary work and environments. With that, novel approaches to support caregiver well-being and cultural shifts that support growth, safety, and flourishing in practice environments are being discussed globally. Fortunately, there is an abundance of resources, tools, and approaches that have been identified and developed to support the health and quality of professional life for humane caregivers that can be drawn upon and applied to the many veterinary ecosystems.

Although deer were introduced into New Zealand in the nineteenth century (Husheer et al. 2003), commercial deer farming itself only became legal in New Zealand in 1969 following the introduction of the New Zealand government’s Noxious Animals Amendment Act 1967 and the Deer Farming Regulations 1969 (Challies 1991). Interest in deer farming increased rapidly in the early 1970s (Pollard and Wilson 2002), with exports of venison, antler, and by-products now worth around NZD$240 million for the year ended September 2020 (B+LNZ 2021). Most of the deer farmed in New Zealand are Cervus elaphus, including the European red deer, North American wapiti, and their hybrids, with a smaller number of fallow deer (Dama dama) also farmed (Mason 1994). There have been a small number of reports of musculoskeletal problems in New Zealand deer including fractures (Wilson 1981; Audigé et al. 2001), osteochondrosis secondary to copper deficiency (Thompson et al. 1994; Audigé et al. 1995), angular limb deformities (Beatson et al. 2011), epiphysitis and osteomyelitis (Badger 1982), foot abscesses (Wilson 1981), polydactyly in red and sika deer (Daniel 1967; Davidson 1971) and outbreaks of lameness associated with Bacteroides nodosus (Skerman 1983) and Fusobacterium necrophorum (Ingram and Gill 2010). However, there have been no reports of bone sequestra in deer in New Zealand, and a literature search conducted using the search terms “deer AND sequestrum AND lameness” in Web of Science on 12 January 2022, found no further results from overseas. On 13 August 2021 a rising 1-year-old (R1) red deer hind weighing 86 kg with a body condition score (BCS) of 2.5/5 presented with severe lameness of the right rear leg. The hind was part of a group of 55 weaned R1 deer, grazing at pasture. Examination of the leg identified a soft, painful swelling on the medial aspect of the metatarsal bone, mid-way between the hock and fetlock. The swelling was not freely movable and seemed adherent to the underlying bone, no crepitus or mobility was noticed on palpation or manipulation of the metatarsus. Differential diagnoses included osteomyelitis with or without bone sequestration, incomplete fracture, and neoplasia although this was less likely due to the patient’s signalment. Radiographic imaging of the leg was sought to confirm the diagnosis. However, the SARS-CoV-2 lockdown response mandated by the New Zealand Government (https://www.health.govt.nz/) meant this had to be postponed until after restrictions were lifted.
