Abstract
OBJECTIVE
To evaluate local temperature differences directly over and adjacent to small intestinal foreign body obstruction (FBO) using infrared thermography (IRT) in dogs.
ANIMALS
49 client-owned dogs were initially enrolled.
METHODS
In a prospective, clinical observational study, IRT was utilized to compare median small intestinal (SI) surface temperature differences at the site of FBO and segments oral and aboral before and after surgical resolution from April 24, 2019, to July 19, 2020. These differences were evaluated for correlation with canine acute patient physiologic and laboratory evaluation fast (APPLEfast) scoring, lactate, foreign body material (hard vs soft), and blood pressure.
RESULTS
There was not a significant surface temperature difference between SI segments at the site of FBO, oral or aboral. After resolution of obstruction, there was a significant decrease in median temperature directly over the FBO (2.4 °C; IQR, −2.55 to 10.6 °C; P = .0043). A decrease in surface temperature of the oral SI segment was appreciated with FBO due to hard material (−1.7 °C; IQR, −5.2 to 3.4 °C), whereas soft material had an increase in SI surface temperature oral to the FBO (+1.1 °C; IQR, 0.3 to 3.2 °C). This difference did not achieve significance (P = .08; Z = 1.75). No correlation was found between APPLEfast, lactate, or blood pressure and SI segment temperatures.
CLINICAL RELEVANCE
IRT may be useful diagnostic modality to identify changes in small intestinal surface temperature relating to FBO. Further evaluation is warranted to determine if IRT may be a clinically useful to evaluate intestinal perfusion.
Abstract
OBJECTIVE
To describe the feasibility and technique for performing laparoscopic ultrasound (LUS) of the liver in dogs.
ANIMALS
12 client-owned dogs presenting for elective laparoscopic surgery from January 1, 2022, to October 31, 2022.
METHODS
Laparoscopic exploration and LUS of the liver were performed in all dogs. Dogs were positioned in reverse Trendelenburg and laterally rotated to facilitate access to all liver lobes. Time to perform laparoscopic exploration and LUS, ability to visualize and access each liver lobe entirely, and any complications were recorded. Each dog underwent an elective laparoscopic procedure. The surgeon completed a National Aeronautics and Space Administration Task Load Index (NASA-TLX) questionnaire after surgery.
RESULTS
Mean body weight was 25.9 kg (SD, ± 4.1 kg; range, 5.7 to 62 kg). All liver lobes were scanned to the level of the hilus in 10/12 dogs. In 2 dogs, the caudate lobe could not be completely imaged. Median time to perform LUS was 9 minutes (IQR, 5 to 16.5 minutes), and median NASA-TLX score was 9/100 (IQR, 6.3 to 20). There was a significantly strong negative correlation between time to perform LUS (r = −0.77; P = .0037) and NASA-TLX score (r = −0.84; P = .0006) with trial number. Minor complications occurred in 2 dogs during laparoscopic exploration. No complications occurred during LUS.
CLINICAL RELEVANCE
LUS was feasible and safe in all dogs. The right lateral and caudate lobes were occasionally challenging to access. Technical demand and time to perform LUS improved with experience, suggesting a learning curve. Evaluation of LUS in dogs with clinical disease is warranted.
Abstract
OBJECTIVE
To describe the clinical presentation, diagnostic imaging findings, surgical technique, histopathological diagnosis, and postoperative outcome in 3 cats with extensive vaginal masses.
ANIMALS
Medical records of cats diagnosed with vaginal masses that had a bilateral pubic and ischial osteotomy and vaginectomy between 2004 and 2022 were retrospectively reviewed. Three cats met the inclusion criteria.
CLINICAL PRESENTATION
Histopathological diagnosis included T-cell–rich B-cell lymphoma (n = 1), mycetoma (1), and vaginal polyp (1). Diagnostic imaging included CT (n = 2) and MRI (1), and tumor length/width/height percentages in relation to the pelvic dimensions were 53% X 62% X 63% (case 1), 50% X 100% X 60% (case 2), and 150% X 120% X 120% (case 3). A bilateral pubic and ischial osteotomy was performed in all 3 cases.
RESULTS
All 3 cases developed mild pelvic-limb splaying postoperatively; all resolved within 8 weeks, and 2 cases fully resolved within 14 days. Two of the 3 cases presented with mild stranguria postoperatively, which resolved fully in both cases.
CLINICAL RELEVANCE
Vaginal neoplasia, either malignant or benign, is infrequently reported in cats in the veterinary literature. Bilateral pubic and ischial osteotomy for resection of vaginal masses in cats is a successful surgical approach, offering good exposure for resection of large vaginal masses, with minimal postoperative complications.
Abstract
Cleft palate is the most common congenital orofacial defect in dogs. Although this topic has been extensively studied in experimental dogs, current literature on clinical patients is limited to case reports and small case series studies with many individual opinions based on experience. This narrative review summarizes the literature of the last 10 years with application to clinical practice, focusing on the preparation of the patient until surgery, options for surgical management, and perioperative complications. Surgical treatment must be performed to obtain separation between the nasal/nasopharyngeal and oral/oropharyngeal passages. This will allow the dog to have independent function and reduce clinical signs associated with food, water, and other foreign material entering the respiratory tract. Surgical treatment has good to excellent outcomes when the procedure is carefully planned and appropriately executed despite the high rates of postoperative oronasal fistula reported.
Abstract
OBJECTIVE
To define cyclic changes in anti-Müllerian hormone (AMH), inhibin-B, and progesterone concentrations and establish statistically valid, population-based clinical reference ranges in queens.
ANIMALS
Cyclic queens (fertile, n = 6; infertile, 6) from an institutional breeding colony were blood sampled longitudinally, each for over 2 months, between November 2021 and February 2022, and residual serum samples from intact (n = 205) and ovariohysterectomized (49) queens from clinical submissions were used to establish reference ranges for intact and spayed females.
METHODS
AMH and inhibin-B were measured using commercially available ELISAs, progesterone was measured using an in-house ELISA, and 90% CIs were calculated from these data.
RESULTS
AMH and inhibin-B fluctuated in a highly correlated, cyclic pattern in 3 queens that did not ovulate immediately, whereas AMH declined as progesterone increased, indicative of ovulation, which occurred spontaneously early in the sampling period in 3 others; statistically valid reference ranges were established in intact and ovariohysterectomized females.
CLINICAL RELEVANCE
Cyclic changes in hormone profiles were defined, providing relevant context for interpreting results in cases seeking to determine gonadal status (presence or absence of gonadal tissue) on the basis of established, population-based reference ranges reported here for cats for the first time.
Abstract
OBJECTIVE
To examine the prevalence and context of one-health conversations between veterinarians and clients in companion animal practice.
SAMPLE
A random selection of 60 companion animal veterinarians; a convenience sample of 917 interactions from Southern Ontario, Canada. Of these, 100 audio-video–recorded interactions including 47 of 60 veterinarians were randomly selected for inclusion in this study.
METHODS
Audio-video recordings were made of veterinarian-client-patient interactions between November 2017 and January 2019. A researcher-generated coding framework was developed and used to assess the prevalence and content of one-health topics communicated during veterinary appointments.
RESULTS
Of the interactions assessed, 60 were preventive care and 40 were health problem appointments. Further, 78% (78/100) included at least 1 discussion related to one health. One-health topics included zoonoses (28% [28/100]), animal behavior (25% [25/100]), illness/disease (20% [20/100]), activity level/exercise (16% [16/100]), nutrition (16% [16/100]), dentistry (6% [6/100]), body weight (3% [3/100]), animal welfare (3% [3/100]), dog/cat bites (2% [2/100]), cannabis (2% [2/100]), and aging (1% [1/100]). Zoonotic diseases were mentioned in 65 appointments, 28 of which evolved into a one-health discussion. Antibiotics were discussed in 27 appointments, none of which were discussed in relation to one health (eg, antimicrobial resistance).
CLINICAL RELEVANCE
Findings suggest that one-health topics are raised within most veterinary appointments. Opportunities exist for more comprehensive one-health conversations between veterinarians and their clients, particularly in relation to zoonotic diseases and antimicrobials.
Abstract
OBJECTIVE
To compare and contrast the views of benefits and general work conditions of participants working in corporate hospitals compared to those working in privately owned hospitals.
SAMPLE
Veterinary members of the Veterinary Information Network (VIN) working as associate veterinarians in corporate- or privately owned hospitals.
METHODS
An electronic survey distributed via the VIN data collection portal.
RESULTS
A total of 896 responses from associate veterinarians working full time were received, of which 286 (31.9%) reported working in private practice and 610 (68.1%) in corporate practice. Fifty-five percent of participants indicated a preference for working in private practice compared to 12% preferring corporate practice. Veterinarians working in corporate practice were more likely to report receiving insurance (health, dental, life, and short-term disability), mental wellness programs (eg, counseling), wellness mobile apps, VIN membership, and continuing education paid by their employer than those working in privately owned practices. However, participants in private practice reported higher satisfaction with feeling known as an individual by upper management, hospital culture, the ability to fire difficult or abusive clients, and mentorship. Those working in corporate practices reported feeling more pressure than those in private practice to generate revenue and see more clients per shift.
CLINICAL RELEVANCE
There are positives and negatives of corporate-owned hospitals when compared to privately owned practices. Corporate hospitals may be well positioned to make large organizational-level changes that can improve work culture and, as a result, the well-being and retention of small animal practitioners.
Abstract
OBJECTIVE
To objectively measure the current demographic makeup of the American College of Veterinary Surgeons (ACVS) diplomates and to develop a survey tool to be used as a metric to measure future changes in the ACVS demographic profile.
SAMPLE
737 ACVS diplomates.
METHODS
A 14-item electronic survey was sent to 2,199 ACVS diplomates between August 25 and September 9, 2021, via email. Survey items included demographic information as well as perceptions about the ACVS and diversity, equity, and inclusion (DEI). Responses were quantitatively and qualitatively analyzed.
RESULTS
The survey response rate was 34% (737/2,199). The median age category among respondents was 45 to 54. The median years in practice as a diplomate was 11 to 15. The majority of respondents identified as white/Caucasian and heterosexual, with male and female respondents being similarly represented. Most respondents identified English as their first language. Few considered themselves first-generation college graduates or identified as disabled. Many respondents considered DEI to be an important initiative to promote in the ACVS.
CLINICAL RELEVANCE
Findings suggested that the majority of ACVS respondents are supportive of DEI efforts. This study also serves as an objective analysis that can be reassessed in the future to determine the success of such initiatives.
