Addition of a metoclopramide constant rate infusion to prevent ptyalism, regurgitation and vomiting in brachycephalic dogs undergoing spinal surgery.

OBJECTIVE: To assess whether adding metoclopramide to a protocol of maropitant and pantoprazole would reduce incidence of ptyalism, vomiting and regurgitation in brachycephalic dogs undergoing thoracolumbar spinal surgery. STUDY DESIGN: Randomized blinded controlled trial. ANIMALS: A total of 43 brachycephalic dogs undergoing thoracolumbar spinal surgery. METHODS: In addition to a standardized anaesthetic regimen, dogs were randomized to be administered either a 2 mg kg-1 day-1 metoclopramide constant rate infusion (CRI) or a saline solution at an equivalent infusion rate, started after anaesthetic induction and discontinued 5 hours after tracheal extubation. The presence of vomiting, regurgitation and pytalism, and short form of the Glasgow Composite Pain Scale pain scores were assessed by a blinded observer hourly for 4 hours, starting 1 hour postextubation. RESULTS: Regurgitation occurred in six dogs postoperatively; three dogs were in the placebo group and three in the metoclopramide group. The odds ratio (OR) of regurgitation after surgery did not differ between groups [OR: 0.76, 95% confidence interval (CI): 0.13-4.3, p = 0.76]. The odds of observing ptyalism at 3 and 4 hours was approximately 15 times less than 1 hour postoperatively (both OR: 15.4, 95% CI: 1.8-130.7, p = 0.012) and did not differ based on the addition of metoclopramide (OR: 0.73, 95% CI: 0.07-8.0, p = 0.79). The odds of observing pain did not change over time and did not differ based on the addition of metoclopramide (OR: 0.71, 95% CI: 0.12-4.2, p = 0.71). Vomiting did not occur during the study (0.0%, 95% CI: 0.0-8.2%). No adverse effects were observed during the study period in either group. CONCLUSIONS AND CLINICAL RELEVANCE: The addition of a metoclopramide CRI to maropitant and pantoprazole did not result in a significant reduction in ptyalism or regurgitation in brachycephalic dogs undergoing thoracolumbar spinal surgery.

Third-generation cephalosporin resistant Escherichia coli in dogs and cats in Germany in 2019-2021.

OBJECTIVES: Antimicrobial resistance (AMR) poses a worldwide challenge, threatening global health. The objective of this research was to determine the 3rd generation cephalosporin resistance (3GCR) proportion in Escherichia (E.) coli isolated from clinical samples of dogs and cats in Germany. METHODS: The study utilized result data from antimicrobial susceptibility testing (AST) of isolates obtained from diagnostic samples collected from dogs and cats send in for bacterial examination. Data includes AST results from 3,491 veterinary practices in Germany spanning the years 2019 to 2021, representing 33.1% of practices and clinics nationwide. Out of 175,171 clinical samples, a total of 25,491 E. coli strains (14,6%) were evaluated for their susceptibility to antimicrobials, in particular the 3rd generation cephalosporin cefovecin, but also aminoglycosides (gentamicin, GEN), fluoroquinolones (enrofloxacin, ENR), tetracyclines (doxycycline), phenicols (chloramphenicol), folate pathway inhibitors (sulfamethoxazole + trimethoprim), and nitrofurans (nitrofurantoin). RESULTS: The cefovecin resistance proportion was 11.6% in the study period. Geographical analysis showed local variations in 3GCR in E. coli of ±3%. Regarding all E. coli isolates investigated, resistance proportions were observed as follows: 12% for sulfamethoxazole-trimethoprim, 7% for enrofloxacin, 8% for chloramphenicol and 4% for gentamicin. Notably, 3GCR E. coli showed significantly higher resistance proportions, specifically 30% for sulfamethoxazole-trimethoprim, 28% for chloramphenicol, 18% for enrofloxacin and 14% for gentamicin. CONCLUSIONS: This study represents the first of its kind to utilize an extensive dataset encompassing dogs and cats across Germany. Companion animals have close contact to their owners and transmission of 3GCR between them is likely as well as acquisition from other environmental sources. Resistance proportions (6.7%) against the antibiotic ceftazidime as reported by the German AMR surveillance for human medicine were lower than in our veterinary data. Our study provides an overview of the current 3GCR resistance proportion in Germany and demonstrates the importance of integrated AMR monitoring.

Whole-genome sequence analysis of canine parvovirus reveals replacement with a novel CPV-2c strain throughout India.

Canine parvovirus (CPV) infection causes severe gastroenteritis in canines, with high mortality in puppies. This virus evolved from feline panleukopenia virus by altering its transferrin receptor (TfR), followed by the emergence of CPV-2 variants in subsequent years with altered immunodominant amino acid residues in the VP2 protein. While previous studies have focused on the VP2 gene, there have been fewer studies on non-structural protein (NS1 and NS2) genes. In the present study, CPV genome sequences from clinical samples collected from canines throughout India in 2023, previous Indian CPV isolates from 2009-2019, and the current Indian CPV vaccine strain were compared. The study showed that the CPV-2c (N426E) variant had almost completely replaced the previously dominant CPV-2a variant (N426) in India. The Q370R mutation of VP2 was the most common change in the recent CPV-2c strain (CPV-2c 370Arg variant). Phylogenetic analysis showed the existence of three clades among the recent CPV-2c strains, and sequence analysis identified several new sites of positive selection in the VP1 (N-terminus), VP2, NS1, and NS2 protein-encoding genes in recent CPV strains, indicating the emergence of new CPV-2c variants with varied antigenic and replication properties. The predominant 'CPV-2c 370Arg variants' were grouped with the Chinese and Nigerian CPV-2c strains but were separate from the CPV vaccine strain and earlier isolates from our repository. VP2 epitope analysis predicted nine amino acid variations (including two new variations) in four potential linear B-cell epitopes in the CPV-2c 370Arg variants that might make vaccine failure more likely. This pan-Indian study lays the foundation for further research concerning the dynamics of virus evolution and understanding genetic mutations.

Neolithic Yersinia pestis infections in humans and a dog.

Yersinia pestis has been infecting humans since the Late Neolithic (LN). Whether those early infections were isolated zoonoses or initiators of a pandemic remains unclear. We report Y. pestis infections in two individuals (of 133) from the LN necropolis at Warburg (Germany, 5300-4900 cal BP). Our analyses show that the two genomes belong to distinct strains and reflect independent infection events. All LN genomes known today (n = 4) are basal in the phylogeny and represent separate lineages that probably originated in different animal hosts. In the LN, an opening of the landscape resulted in the introduction of new rodent species, which may have acted as Y. pestis reservoirs. Coincidentally, the number of dogs increased, possibly leading to Y. pestis infections in canines. Indeed, we detect Y. pestis in an LN dog. Collectively, our data suggest that Y. pestis frequently entered human settlements at the time without causing significant outbreaks.

Veterinary perspectives on the urbanization of leishmaniosis in Morocco.

BACKGROUND: Leishmaniosis caused by Leishmania infantum, L. major and L. tropica is endemic in Morocco. Growing evidence of both human and canine Leishmania infections in urban centres has been reported. Since many forms of the disease are zoonotic, veterinarians play an important role in leishmaniosis control by intervening at the parasite host level. This study aimed to bring together One Health principles to connect canine and feline leishmaniosis epidemiology within urban centres of Morocco (Rabat and Fez) and assess the level of awareness of Moroccan veterinarians about facing this threat. METHODS: A molecular survey was conducted for Leishmania DNA detection in canine (n = 155) and feline (n = 32) whole-blood samples. Three conventional polymerase chain reaction (PCR) protocols were implemented. The first PCR aimed at identifying infected animals by targeting Leishmania spp. kinetoplast minicircle DNA (kDNA). The second and third PCR targeted the Leishmania internal transcribed spacer region (ITS-1) and the Leishmania small subunit ribosomal RNA (SSUrRNA) gene, respectively, aiming at identification of the infecting species after Sanger sequencing-positive amplicons. Total immunoglobulin G (IgG) against Leishmania spp. was evaluated in 125 dogs by enzyme-linked immunosorbent assays (ELISA) using an in-house protocol, including three Leishmania-specific antigens (SPLA, rKDDR and LicTXNPx). Sera from 25 cats were screened for total IgG to Leishmania spp. by an indirect immunofluorescence antibody test (IFAT). An online questionnaire was presented to Moroccan veterinarians addressing their knowledge and practices towards animal leishmaniosis. RESULTS: Overall, 19.4% of the dogs tested positive for Leishmania kDNA and ITS-1 and sequencing revealed infection with L. infantum among PCR-positive dogs. These animals presented a wide range of ELISA seropositivity results (16.7%, 34.9% and 51.6%) according to the tested antigens (rKDDR, SPLA and LicTXNPx, respectively). Use of kDNA-PCR revealed 12.5% cats positive to Leishmania spp. otherwise found to be seronegative by IFAT. CONCLUSIONS: A considerable prevalence of infection was identified in dogs from urban centres of Morocco. Additionally, this is the first report of feline infection with Leishmania spp. in this country and in urban settings. Moroccan veterinarians are aware that animal leishmaniosis is endemic in Morocco, representing a public health threat, and are knowledgeable about canine leishmaniosis diagnosis and treatment.

The PB2 I714S mutation influenced mammalian adaptation of the H3N2 canine influenza virus by interfering with nuclear import efficiency and RNP complex assembly.

Avian influenza viruses (AIVs) are the origin of multiple mammal influenza viruses. The genetic determinants of AIVs adapted to humans have been widely elucidated, however, the molecular mechanism of cross-species transmission and adaptation of AIVs to canines are still poorly understood. In this study, two H3N2 influenza viruses isolated from a live poultry market (A/environment/Guangxi/13431/2018, GX13431) and a swab sample from a canine (A/canine/Guangdong/0601/2019, GD0601) were used to investigate the possible molecular basis that determined H3N2 AIV adapting to canine. We found that GD0601 exhibited more robust polymerase activity in cells and higher pathogenicity in mice compared with its evolution ancestor H3N2 AIV GX13431. A series of reassortments of the ribonucleoprotein (RNP) complex showed that the PB2 subunit was the crucial factor that conferred high polymerase activity of GD0601, and the substitution of I714S in the PB2 subunit of GD0601 attenuated the replication and pathogenicity in mammal cells and the mouse model. Mechanistically, the reverse mutation of I714S in the PB2 polymerase subunit which was identified in AIV GX13431 reduced the nuclear import efficiency of PB2 protein and interfered with the interactions of PB2-PA/NP that affected the assembly of the viral RNP complex. Our study reveals amino acid mutation at the position of 714 in the nuclear localization signal (NLS) area in PB2 plays an important role in overcoming the barrier from poultry to mammals of the H3N2 canine influenza virus and provides clues for further study of mammalian adaptation mechanism of AIVs.

In sickness and health - a questionnaire based study regarding immune mediated diseases and neoplasia in Swedish Nova Scotia Duck Tolling Retrievers.

BACKGROUND: The Nova Scotia Duck Tolling Retriever (NSDTR) has previously been highlighted as a breed at risk for developing immune mediated diseases and cancer. The immune response is of great importance for the development of neoplastic disease and a dysregulated immune response may predispose to cancer. Two of the commonly seen immune mediated diseases in NSDTRs are immune mediated rheumatic disease (IMRD), which bears similarities to systemic lupus erythematosus (SLE) affecting humans, and steroid-responsive meningitis-arteritis (SRMA), which is a non-infectious inflammation of the meninges and the leptomeningeal vessels. The aim of this survey study was to investigate the lifetime prevalence of immune mediated diseases and tumors among Swedish NSDTRs based on owners' information. The study design was cross-sectional. A questionnaire was sent to 4102 persons who owned or had previously owned a NSDTR. The questions concerned information about the dog and its overall health status as well as specific diseases. RESULTS: The response rate was 30%, including 935 live NSDTRs, corresponding to approximately 20% of the current population registered in Sweden (n = 4564), and 177 dead dogs. The surveyed dogs were spread over different ages and sex and corresponded to the typical demographic profile of the general dog population. Of the 935 individuals that were alive, 28 dogs (3%) were reported as previously diagnosed with IMRD and 33 dogs (3.5%) were reported as previously diagnosed with SRMA, one dog was reported to have been diagnosed with both SRMA and IMRD. There were 129 dogs (14%) reported to have or have had a neoplasia of some kind. For the dead dogs (n = 177), almost 40% of the owners reported neoplasia as the main reason for death/euthanasia. CONCLUSION: This study reports an estimated lifetime prevalence of IMRD and SRMA, in the studied population of Swedish NSDTRs, of 3.0 and 3.5% respectively. In this study, 14% of the living dogs (n = 935) were reported to have a neoplasia of some kind and almost 40% of the deceased dogs (n = 177) were euthanized due to neoplasia or suspicion of it.

Detection and Molecular Characterization of Kobuviruses: An Agent of Canine Viral Diarrhea.

Clarifying the etiology of diarrhea cases of unknown cause is important in the fight against enteric infections. In this study, we aimed to investigate the role of canine kobuvirus (CaKoV), in cases of diarrhea of unknown origin in dogs. A total 121 swab samples from dogs with diarrhea were collected. Molecular analyses of the samples were performed. For this purpose, after the sequence reaction, a phylogenetic tree was created, and bioinformatics analyses were performed. The prevalence rate of CaKoV in the sampled population was determined as 16.5% (20/121). The presence of parvovirus and coronavirus, which are common viral agents in CaKoV-positive dogs, was determined as 35% (7/20) and 10% (2/20), respectively. The rate of dogs with only CaKoV detected was 65% (13/20). Phylogenetic analysis of CaKoV strains clustered together closely related to reference strains. There are very limited studies on the role of CaKoV in the etiology of diarrhea cases of unknown cause in dogs around the world. So far, only one study has been done on CaKoV in Turkey. In this report which includes molecular characterization and epidemiological data on CaKoV determined the importance of CaKoV in cases of diarrhea of unknown origin. More comprehensive studies are needed to better understand the pathogenesis, epidemiology, and biology of CaKoV and to determine effective strategies to combat it.

Standardization of quantitative PCR (qPCR) method to detect the level of parasitaemia in Babesia gibsoni infected dogs.

The present investigation aimed to quantitatively assess the level of parasitemia in dogs using qPCR.The dogs selected for this study were infected with the haemoprotozoan parasite Babesia gibsoni. In the study, dogs diagnosed with babesiosis were divided into two groups (n = 12) and subjected to distinct treatment strategies. The first group received clindamycin-metronidazole-doxycycline (CMD) therapy, while the second group was treated with a combination of buparvaquone-azithromycin (BPV-AZM). The level of parasitemia in the infected dogs was determined using an absolute quantification-based qPCR method. This assessment was conducted both prior to initiating the treatment and on the 10th day following the commencement of the treatment protocols. On the tenth day after the initiation of treatment, the CMD group exhibited a lower level of parasitemia in comparison to the BPV-AZM group. In the CMD treated groups, the mean parasitemia decreased from 4.9E + 06 to 3.4E + 06, indicating a reduction in parasitic load. Conversely, in the BPV-AZM treatment groups, the mean parasitemia increased from 1.62E + 06 to 2.87E + 06, suggesting an increase in parasitic load. On the 10th day, the CMD-treated group demonstrated a statistically significant decline in the level of parasitemia, with a P-value of ≤0.001. This indicates a strong and significant reduction in parasitic load following the CMD treatment. Therefore, the absolute quantification-based qPCR method could effectively assess the initial treatment response by measuring the level of parasitemia.

Prevalence and antimicrobial resistance trends among vaginal bacteria isolates from pregnant bitches.

Many of the reproductive tract infections in the bitches are caused by bacteria that can normally be present on the vaginal mucosa. These bacteria also might have an important role as the cause responsible for pregnancy loss and fetal deaths. The choice of antibiotic therapy for the pregnant animal is narrow and represents a severe problem in veterinary practice, especially due to increased antimicrobial resistance. Due to incorrect antimicrobials use in breeding kennels, the aim of the present study was to assess the occurrence of the bacterial flora isolated from the pregnant bitches and their antibiotic sensitivity. The study was carried out at the private Veterinary clinic in Novi Sad, Serbia. The vaginal swabs were taken from 60 bitches diagnosed with pregnancy and were sent to be laboratory tested. Based on the results, the most common isolated pathogens were Staphylococcus pseudintermedius (20%) and beta-hemolytic streptococci (18.33%). Furthermore, significant resistance to antibiotics from beta-lactams group was detected. It is of particular importance that antimicrobial treatment be evidence based in order to reduce the overuse of antimicrobials due to increased concern regarding antimicrobial resistance.

Cutaneous and visceral phaeohyphomycosis in an immunocompetent golden retriever.

A 3-year-old castrated male golden retriever was presented for evaluation of 2 cutaneous masses along the abdominal midline and a 6-month history of progressive lethargy and inappetence. Two years earlier, the dog underwent a gastrotomy to retrieve a foreign object and recovered uneventfully. Fluid aspirated from the lesions was culture-negative for aerobic and anaerobic bacterial growth. Abdominal ultrasound demonstrated a large intra-abdominal mass with apparent communication with the cutaneous lesion, along with gossypiboma from the previous laparotomy. Neoplasia or a sterile abscess were suspected. Exploratory laparotomy was performed and revealed that the intra-abdominal mass was adhered to the abdominal midline and the greater curvature of the stomach. The masses and affected portions of the body wall and stomach were resected and histopathology was consistent with phaeohyphomycosis. Antifungal therapy with voriconazole (6.3 mg/kg, PO, q12h) was initiated. At 1 mo after surgery, all clinical signs had resolved. At 4 and 7 mo after surgery, the dog continued to thrive despite 2 small masses, seen on abdominal ultrasound imaging on the intra-abdominal midline, suggestive of reoccurrence. Continued voriconazole therapy was administered in lieu of further surgical excision. One year after surgery, the masses were no longer present on ultrasonographic evaluation. Phaeohyphomycosis is a rare, opportunistic fungal infection that typically affects the dermis and subcutis of immunocompromised dogs. This is the first report of phaeohyphomycosis in an immunocompetent dog and involving the dermis, subcutis, and abdominal viscera. Key clinical message: This case adds to the very limited literature on phaeohyphomycosis in dogs and illustrates that surgery could be a risk factor for infection, even in dogs with no known underlying disease or immunodeficiency.

Phéohyphomycose cutanée et viscérale chez un golden retriever immunocompétentUn golden retriever mâle castré de 3 ans a été présenté pour évaluation de 2 masses cutanées le long de la ligne médiane abdominale et d'un historique de léthargie et d'inappétence progressive depuis 6 mois. Deux ans plus tôt, le chien avait subi une gastrotomie pour récupérer un objet étranger et s'était rétabli sans incident. Le liquide aspiré des lésions était négatif en culture pour la croissance bactérienne aérobie et anaérobie. L'échographie abdominale a mis en évidence une masse intra-abdominale importante avec une communication apparente avec la lésion cutanée, ainsi qu'un gossyibome issu de la laparotomie précédente. Un néoplasme ou un abcès stérile ont été suspectés. Une laparotomie exploratoire a été réalisée et a révélé que la masse intra-abdominale adhérait à la ligne médiane abdominale et à la grande courbure de l'estomac. La masse et les parties affectées de la paroi corporelle et de l'estomac ont été réséquées et l'histopathologie était compatible avec une phaeohyphomycose. Un traitement antifongique par voriconazole (6,3 mg/kg, PO, toutes les 12 heures) a été instauré. Un mois après l'intervention chirurgicale, tous les signes cliniques avaient disparu. À 4 et 7 mois après l'intervention chirurgicale, le chien a continué à bien allé malgré 2 petites masses, observées à l'échographie abdominale sur la ligne médiane intra-abdominale, évocatrices d'une réapparition. La poursuite du traitement par le voriconazole a été administrée au lieu d'une nouvelle excision chirurgicale. Un an après l'intervention chirurgicale, les masses n'étaient plus présentes à l'évaluation échographique. La phaeohyphomycose est une infection fongique rare et opportuniste qui affecte généralement le derme et le sous-cutané des chiens immunodéprimés. Il s'agit du premier rapport de phaeohyphomycose chez un chien immunocompétent et impliquant le derme, le tissu sous-cutané et les viscères abdominaux.Message clinique clé :Ce cas s'ajoute à la littérature très limitée sur la phaeohyphomycose chez le chien et illustre que la chirurgie pourrait être un facteur de risque d'infection, même chez les chiens sans maladie sous-jacente ou immunodéficience connue.(Traduit par Dr Serge Messier).

Ultrasound- and fluoroscopy-guided percutaneous transhepatic shunt attenuation using a vascular plug in a complex canine intrahepatic portosystemic shunt.

A 5-month-old Pembroke Welsh corgi dog was presented with a 3-month history of lethargy, inappetence, polyuria/polydipsia, and neurological signs. A diagnosis of a complex multiple intrahepatic portosystemic shunt (IHPSS) configuration was obtained by computed tomography angiogram, abdominal ultrasonography, and perioperative fluoroscopic angiography. The IHPSS was successfully attenuated by shunt embolization with a vascular plug, using a direct percutaneous hepatic approach under ultrasonographic and fluoroscopic guidance. Long-term (4 y) follow-up revealed resolution of all clinical signs. The owner elected to continue dietary modification and lactulose treatment indefinitely and the outcome was considered good. Key clinical message: Direct percutaneous hepatic approach could be considered for IHPSS attenuation in select cases where traditional transvenous approach access is considered challenging.

Atténuation percutanée trans-hépatique guidée par échographie et fluoroscopie d'un shunt porto-systémique intrahépatique canin complexe à l'aide d'un bouchon vasculaireUn chien Pembroke Welsh corgi âgé de 5 mois a été présenté avec des antécédents de léthargie, d'inappétence, de polyurie/polydipsie et de signes neurologiques depuis 3 mois. Un diagnostic de configuration complexe de shunt porto-systémique intrahépatique multiple (IHPSS) a été obtenu par angiographie par tomodensitométrie, échographie abdominale et angiographie fluoroscopique périopératoire. L'IHPSS a été atténué avec succès par embolisation du shunt avec un bouchon vasculaire, en utilisant une approche hépatique percutanée directe sous guidage échographique et fluoroscopique. Un suivi à long terme (4 ans) a révélé une résolution de tous les signes cliniques. Le propriétaire a choisi de poursuivre indéfiniment la modification du régime alimentaire et le traitement au lactulose et le résultat a été considéré comme bon.Message clinique clé :Une approche hépatique percutanée directe pourrait être envisagée pour l'atténuation de l'IHPSS dans certains cas où l'accès par voie trans-veineuse traditionnelle est considéré comme difficile.(Traduit par Dr Serge Messier).

Intestinal duplication in a miniature Schnauzer dog.

A 9-week-old miniature Schnauzer dog was brought to a veterinary clinic because of an acute onset of vomiting. A 2 to 3-centimeter, round, firm structure in the mid-abdomen was palpated with a repeatable pain response. An exploratory laparotomy revealed a grossly cystic-appearing mass on the distal ileum. Resection and anastomosis were conducted. The histopathology report concluded the structure was an intestinal duplication, a rare congenital abnormality, with the structure sharing an outer muscular layer with the normal intestine. The resection was considered completely excised. The puppy recovered well and was clinically normal on follow-up examinations. The findings from this case suggest congenital abnormalities should always be included on a differential diagnosis list for all young animals, regardless of the presenting complaint.

Duplication intestinale chez un Schnauzer miniatureUn Schnauzer miniature âgé de 9 semaines a été présenté à une clinique vétérinaire pour cause d'apparition de vomissements aigus. Une structure ferme et ronde, de 2 à 3 cm de diamètre au milieu de l'abdomen était palpée avec une réponse à la douleur répétée. Une laparotomie exploratoire a révélé la présence d'une masse d'apparence kystique sur l'iléon distal. Une résection et une anastomose ont été effectuées. Le rapport d'histopathologie concluait que la structure était une duplication intestinale, une anomalie congénitale rare, et que la structure partageait une couche musculaire externe avec l'intestin normal. La résection a été considérée comme complètement excisée. Le chiot a bien récupéré et était cliniquement normal lors des examens de suivi. Les trouvailles dans le cas présent suggèrent que les anomalies congénitales devraient toujours être incluses dans la liste des diagnostics différentiels pour les jeunes animaux, indépendamment de la raison pour la consultation.(Traduit par Dr Serge Messier).

Internet-based survey on diagnosis and treatment recommendations for medial shoulder syndrome and instability in dogs.

Objective: The aim of this study was to document perceived frequency of medial shoulder syndrome and instability (MSS/MSI) among dogs, and preferred diagnostic and treatment options related to the condition, among American or European Colleges of Veterinary Surgeons (ACVS/ECVS) diplomates, American College of Veterinary Sports Medicine and Rehabilitation (ACVSMR) diplomates, and dual diplomates of ACVS/ECVS and ACVSMR (double-Boarded diplomates). Procedure: An invitation to complete an online survey was sent to diplomates via email listservs. Results: The known response rate for the survey was 15.8% (160 of 1014 email addresses). There was a difference (P = 0.006) among groups in number of cases of MSS/MSI seen, with ACVS/ECVS diplomates and double-Boarded diplomates seeing 0 to 5 cases per year (80.7 and 72.7%, respectively) and ACVSMR diplomates (32% of total respondents) seeing 11 to 26+ cases annually. The majority of all respondents (56.4%) felt the likely cause of MSS/MSI to be chronic/repetitive strain. Diagnostically, most respondents (78%) relied on shoulder abduction angles; however, most felt it was a questionable or somewhat accurate diagnostic test. The ACVSMR diplomates (88%) relied on musculoskeletal ultrasound as their preferred diagnostic modality, compared to only 35% of ACVS/ECVS diplomates and 45% of double-Boarded diplomates. Preferred treatment was rehabilitation with surgery for unresponsive cases, as reported by 86.9% of all respondents. Preferred surgical treatment was prosthetic ligament reconstruction (62.7%). Conclusion: Despite the low known response rate of this survey, there were significant differences among specialties regarding frequency of MSS/MSI cases seen per year and preferred diagnostic modalities. However, there were no differences among specialties regarding the suspected underlying causes of MSS/MSI and initial treatment strategies.

Enquête en ligne sur le diagnostic et les recommandations thérapeutiques pour le syndrome et l'instabilité médiale de l'épaule chez le chien. Objectif: Le but de cette étude était de documenter la fréquence perçue du syndrome et de l'instabilité médiale de l'épaule (MSS/MSI) chez les chiens, ainsi que les options de diagnostic et de traitement préférées liées à cette maladie, parmi les spécialistes des collèges américains ou européens de chirurgiens vétérinaires (ACVS/ECVS), les spécialistes de l'American College of Veterinary Sports Medicine and Rehabilitation (ACVSMR) et les spécialistes doubles ACVS/ECVS et ACVSMR. Procédure: Une invitation à répondre à un sondage en ligne a été envoyée aux spécialistes via des listes de diffusion de courrier électronique. Résultats: Le taux de réponse connu pour l'enquête était de 15,8 % (160 sur 1 014 adresses courriel). Il y avait une différence (P = 0,006) entre les groupes dans le nombre de cas de MSS/MSI vus, les spécialistes de l'ACVS/ECVS et les spécialistes doubles voyant 0 à 5 cas par an (respectivement 80,7 et 72,7 %) et les spécialistes de l'ACVSMR (32 % du total des répondants) voient 11 à 26+ cas par an. La majorité de tous les répondants (56,4 %) ont estimé que la cause probable du MSS/MSI était une tension chronique/répétitive. Sur le plan diagnostique, la plupart des répondants (78 %) se sont appuyés sur les angles d'abduction de l'épaule; cependant, la plupart estimaient qu'il s'agissait d'un test diagnostique douteux ou quelque peu précis. Les spécialistes de l'ACVSMR (88 %) ont eu recours à l'échographie musculosquelettique comme modalité diagnostique privilégiée, contre seulement 35 % des spécialistes de l'ACVS/ECVS et 45 % des spécialistes doubles. Le traitement préféré était la réadaptation chirurgicale pour les cas qui ne répondaient pas, comme l'ont indiqué 86,9 % de tous les répondants. Le traitement chirurgical préféré était la reconstruction ligamentaire prothétique (62,7 %). Conclusion: Malgré le faible taux de réponse à cette enquête, il existe des différences significatives entre les spécialités concernant la fréquence des cas de MSS/MSI observés par an et les modalités de diagnostic préférées. Cependant, il n'y avait aucune différence entre les spécialités concernant les causes sous-jacentes suspectées de MSS/MSI et les stratégies de traitement initiales.(Traduit par Dr Serge Messier).

Acute respiratory distress syndrome associated with a pheochromocytoma in an adult dog.

A 16-year-old castrated male shih tzu dog was brought to the emergency service because of an acute (24 h) history of gagging, coughing, and lethargy. Physical examination revealed dyspnea concurrent with diffuse, bilateral, pulmonary crackles and wheezes. Oxygen saturation, measured with a pulse oximeter, was < 95%. Thoracic radiographs revealed a multifocal alveolar pattern superimposed over a diffuse interstitial pattern with normal heart size. The dog continued to be dyspneic despite oxygen therapy. In accordance with the radiographic findings, further supportive care was recommended. Due to the unknown prognosis and financial constraints, the owner elected humane euthanasia. Necropsy confirmed a pheochromocytoma and lung changes without evidence of congestive heart failure. Findings were consistent with diffuse alveolar damage. These findings correlated with the dog's clinical diagnosis of acute respiratory distress syndrome (ARDS). No other disease processes associated with ARDS were identified. The purpose of this case report is to describe an unusual presentation of ARDS likely associated with a pheochromocytoma and confirmed by necropsy. Acute respiratory distress syndrome associated with a pheochromocytoma has been described in medical literature but has never been reported in veterinary medicine. Key clinical message: Pheochromocytomas should be added to the list of risk factors associated with ARDS in dogs. Dogs with a suspected diagnosis of pheochromocytoma whose owners elect against surgical removal should be closely monitored for an acute onset of respiratory distress, which could suggest the development of ARDS.

Syndrome de détresse respiratoire aiguë associé à un phéochromocytome chez un chien adulteUn chien shih tzu mâle castré de 16 ans a été amené aux services d'urgence en raison d'antécédents aigus (24 heures) de haut-le-coeur, de toux et de léthargie. L'examen physique a révélé une dyspnée concomitante à des crépitements et des respirations sifflantes diffuses, bilatérales et pulmonaires. La saturation en oxygène, mesurée avec un oxymètre de pouls, était < 95 %. Les radiographies thoraciques ont révélé un motif alvéolaire multifocal superposé à un motif interstitiel diffus avec une taille cardiaque normale. Le chien est resté dyspnéique malgré l'oxygénothérapie. Conformément aux résultats radiographiques, des soins de soutien supplémentaires ont été recommandés. En raison du pronostic inconnu et des contraintes financières, le propriétaire a opté pour l'euthanasie sans cruauté. La nécropsie a confirmé un phéochromocytome et des modifications pulmonaires sans signe d'insuffisance cardiaque congestive. Les résultats concordaient avec des lésions alvéolaires diffuses. Ces résultats étaient en corrélation avec le diagnostic clinique du syndrome de détresse respiratoire aiguë (ARDS) du chien. Aucun autre processus pathologique associé à l'ARDS n'a été identifié. Le but de ce rapport de cas est de décrire une présentation inhabituelle de l'ARDS probablement associée à un phéochromocytome et confirmée par la nécropsie. Le syndrome de détresse respiratoire aiguë associé à un phéochromocytome a été décrit dans la littérature médicale mais n'a jamais été rapporté en médecine vétérinaire.Message clinique clé:Les phéochromocytomes doivent être ajoutés à la liste des facteurs de risque associés à l'ARDS chez le chien. Les chiens avec un diagnostic suspecté de phéochromocytome dont les propriétaires choisissent de ne pas procéder à l'ablation chirurgicale doivent être étroitement surveillés pour détecter l'apparition aiguë d'une détresse respiratoire, ce qui pourrait suggérer le développement d'un ARDS.(Traduit par Dr Serge Messier).
