Materials and Methods A cohort of client-owned dogs was included in this prospective observational study. After induction of general anaesthesia and hair clipping, culture samples were collected from the incisional site of healthy dogs before orthopaedic surgery. The isolated colonies were identified. The susceptibility pattern of staphylococcal isolates was determined using Clinical and Laboratory Standard Institute standards. The staphylococcal susceptibilities to amoxicillin/clavulanic acid and cefpodoxime were compared with cefazolin using two-sided equality of proportions test. Results A total of 391 bacterial isolates were identified in 115 dogs. Bacillus spp. (n = 200) and Staphylococcus spp. (n = 95) were the most common bacteria isolated. Coagulase- positive and -negative staphylococci were isolated in 44 and 38% of dogs respectively. Cefazolin, amoxicillin/clavulanic acid and cefpodoxime staphylococcal susceptibilities were 68, 77 and 76% respectively. There were no significant differences in Staphylococcus spp. susceptibility between amoxicillin/clavulanic acid or cefpodoxime and cefazolin (p = 0.19, p = 0.25). Thirty-six per cent of coagulase-negative staphylococci and 6% of coagulase-positive staphylococci isolated were methicillin resistant. Conclusion Cefazolin, amoxicillin/clavulanic acid and cefpodoxime had similar susceptibilities for staphylococcal isolates. Routine use of amoxicillin/clavulanic acid or cefpodoxime in replace of cefazolin should be practiced with caution.","PeriodicalId":443672,"journal":{"name":"VCOT Open","volume":"03 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129671655","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

All dogs showed a temporary resolution of clinical signs of surgical site infection. Two dogs that received linezolid at the previously reported dose developed drug-associated side effects. The side effects were anorexia, nausea, vomiting and regenerative anaemia. All side effects resolved after the discontinuation of linezolid. Surgical site infection recurred in two dogs 52 and 177 days after discontinuing linezolid respectively. Clinical significance Adverse drug events occurred in dogs receiving oral linezolid at the dosage of 10 to 20 mg/kg. Oral linezolid therapy failed to resolve deep orthopaedic surgical site infections in two out of four dogs. As a tertiary antimicrobial, linezolid should only be used in carefully selected cases while monitoring for drug-associated side effects.","PeriodicalId":443672,"journal":{"name":"VCOT Open","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126624832","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods Two different screw configurations were compared for the NHTP and LCP, modelling short (configuration 1) and long working length (configuration 2). Constructs were tested in compression, perpendicular and tension four-point bending and torsion. Plate surface strain was measured at 12 regions of interest using three-dimensional digital image correlation. Stiffness and strain were compared. Results The LCP was stiffer than the NHTP in all three planes of bending (p < 0.05). The NHTP was stiffer than the LCP in torsion (p < 0.05). The NHTP had greater strain than the LCP during compression bending and torsion (p < 0.0005). The short working length NHTP was stiffer in all three planes of bending and in torsion (p < 0.05) than the longer working length. The short working length LCP was stiffer in compression bending and in torsion (p < 0.05) than the longer working length. The long working length showed greater strain than the short working length at multiple regions of interest. Conclusion In this experimental model of a compressed transverse fracture with a juxta-articular 9 mm fragment, a 2.0 mm LCP with two hybrid screws in the short fragment was stiffer than a 2.0 mm NHTP with three locking screws in the short fragment in three planes of bending but not torsion. Extending the working length of each construct reduced construct stiffness and increased plate strain.","PeriodicalId":443672,"journal":{"name":"VCOT Open","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134354809","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Study Design Goniometric evaluation was performed in triplicate using a universal goniometer. CD dogs were categorized into miniature, small, medium, large and giant sizes, whereas NCD dogs were allocated to small- and medium-size groups. Hence, each of the seven subgroups comprised 11 clinically healthy dogs. For data analysis, the Levene test was used to evaluate homoscedasticity. The means of each joint angle with the means in each group as well as the PROM between the CD and NCD groups was compared by the Student's t-test; meanwhile, the means of the joint angles and ROM among the sizes were compared by analysis of variance, followed by the Tukey test. In those cases, when no homogeneity variance was observed, the Bonferroni test was used. In every case, p ≤ 0.05 was considered significant. Results The articular angles and PROM differed according to the dog size and type, that is, CD or NCD. Conclusion The goniometric values and PROM of dogs depend on the joint type, dog size and chondrodystrophy status. Further studies are necessary to increase the accuracy of the results and to establish the predominant factors governing the differences discovered.","PeriodicalId":443672,"journal":{"name":"VCOT Open","volume":"183 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114146599","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Materials and Methods Open reduction of the tarsal joint was performed followed by combined (1) internal repair (tibial/ fibular malleolar osteosynthesis or primary ligament suture and/or prosthetic ligament repair) and (2) temporary TESF. Stability of the tarsus was determined at short-term follow-up (4–8 weeks postoperatively). Short-term complications were evaluated and midterm outcome assessed by an owner telephone questionnaire. Results Fourteen cats were included of which nine had open TCI. Median time for frame removal was 47 days. Eleven patients had satisfactory stability of the tarsus at short-term follow-up. Catastrophic complications occurred in three cats consisting of extensive skin necrosis of the paw with subsequent hindlimb amputation in two and multiple digit amputations in one cat. Major complications occurred in one cat with persistent TCI requiring pantarsal arthrodesis. Nine cat owners indicated a ‘full or acceptable’ outcome at midterm (median, 1.5 years). Conclusion Close monitoring in the postoperative period until TESF removal is important for early identification of complications. Despite good joint stability at short-term, persistent or recurrent lameness at midterm can occur.","PeriodicalId":443672,"journal":{"name":"VCOT Open","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122822378","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Following intramuscular injection of melarsomine dihydrochloride based on manufacturers' guidelines, two dogs developed acute, progressive, nonambulatory paraparesis or paraplegia. Magnetic resonance imaging was suggestive of epidural steatitis, resulting in compression of the spinal cord and spinal cord oedema. In one dog, emphysematous myositis throughout the lumbar paravertebral muscles was present. Hemilaminectomy with the intent of achieving spinal cord decompression and obtaining specimens for microbiological and histopathological evaluation was performed in both dogs. One dog partially regained function postoperatively whereas the other was euthanatized intraoperatively. Histologically, epidural steatitis was observed in the surviving dog and epidural steatitis, myonecrosis and grey and white matter changes in the spinal cord were observed in the euthanatized dog. Microbiological testing failed to identify bacteria from the affected tissues. Both cases highlight the potential for the development of extensive epidural steatitis and consequent spinal cord compression following intramuscular administration of melarsomine dihydrochloride. Further investigation into the optimal therapeutic intervention in dogs experiencing neurological complications following melarsomine administration is warranted.","PeriodicalId":443672,"journal":{"name":"VCOT Open","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128771895","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
