title: Acoustic Radiation Force Impulse (ARFI) elastography imaging of equine distal forelimb flexor structures

description: ABSTRACT This study set out to determine normal values for acoustic radiation force impulse (ARFI) elastography of the superficial digital flexor tendon, deep digital flexor tendon, accessory ligament of the deep digital flexor tendon and suspensory ligament in horses. Twenty-four horses were submitted to conventional sonographic assessment and elastography imaging (quantitative ARFI method) of distal forelimb tendons and ligaments at nine anatomical regions. Elastograms depicted tendons and ligaments in orange to red tones consistent with greater stiffness. Shear wave velocity was higher in the longitudinal compared to the cross-sectional plane but did not differ significantly between the left and right forelimbs. The suspensory ligament was stiffer compared to remaining structures in the cross-sectional plane. Ligaments were stiffer than tendons and the deep digital flexor tendon was stiffer than the superficial digital flexor tendon in the longitudinal plane. Target structures were stiffer in male compared to female horses and stiffness tended to increase with age. ARFI elastography proved to be a feasible and reproducible imaging modality for assessment of distal forelimb tendons and ligaments in horses. Qualitative features derived from stiffness quantification in these structures can be applied to horses with musculoskeletal disorders, as well as to other animal species.

title: [Frequency of non Tumor Skin Diseases in Dogs in the City of João Pessoa, Paraíba, Brazil (2014-2016)]

description: ABSTRACT Faced with the lack of studies on the frequency of dermatopathies that affect dogs by geographical region in Brazil, the present study aimed to evaluate the frequency of dermatopathies that affect the canine species in the metropolitan region of João Pessoa, Paraíba, Brazil. Data was collected from dogs that underwent dermatological care from September 2014 to December 2016. In addition to the clinical and dermatological examinations, dogs underwent complementary exams, such as cytological, skin scraping, parasitological skin examination, trichogram, bacteriological, mycological, histopathological and/or polymerase chain reaction. During the study period, 1,083 dogs were examined, in which 18.65% (202 /1,083) had some form of non-tumoral dermatopathy. Of the 202 dogs affected, 51.49% (104/202) were males and 48.51% (98/202) females. Of these 202 dogs, thirteen had two diagnoses, totaling 215 dermatopathies. 62.87% (127/202) of the affected dogs were purebred and 37.13% (75/202) were without a defined breed (WDB). The most frequently observed lesions were alopecia, hypotric, macular, erosive and ulcerative, placoid, erythematous areas, as well as comedones, collaretes and seborrhoea. The parasitic dermatopathies were the most frequent (35.35%; 76/215), followed by bacterial dermatopathies (24,19%; 52/215), allergic dermatopathies (20,00%; 43/215), dermatomycosis (17,21%; 37/215), dermatopathies for other causes (2,32%; 5/215) and autoimmune dermatopathies (0.93%; 2/215). Clinical and dermatological examination, including a detailed anamnesis, accurate clinical history and associated complementary exams are important tools for the diagnosis of dermatopathies in dogs. Available literature present some studies with canine dermatopathies frequencies superior to that obtained in the present study; however, the number of animals examined was smaller. In this survey, it was possible to establish the primary and secondary diagnoses in 100.0% of the non-tumoral dermatopathies in dogs, results higher than in previous studies. Probably, the frequency of canine dermatopathies in this region is higher than that observed, thus requiring additional studies with greater sampling.

title: [Phlebotomine fauna and seroprevalence for canine visceral leishmaniasis in urban area from Central-West region of Brazil]

description: ABSTRACT American visceral leishmaniasis (AVL) is a vector-borne zoonosis in which the dog has an important role in the epidemiology of the disease. In Brazil, a high prevalence of canine infection is directly correlated with an increased risk of occurrence of AVL. The aim of this study was to investigate the phlebotomine fauna and seroprevalence of canine visceral leishmaniasis in Pedra 90 region of Cuiabá municipality. For the entomological survey, CDC traps were used from August 2014 to July 2015. In the serological evaluation of dogs, the immunochromatographic test DPP LVC was employed for screening the samples while enzyme-linked immunosorbent assay (Bio-Manguinhos) was used as a confirmatory assay. The previously unreported phlebotomine species Lu. andersoni, Lu. braziliensis, Lu. bourrouli, and Lu. scaffi were added to the phlebotomine fauna of Cuiabá. In addition, the medically important phlebotomine species Lu. cruzi, Lu. flaviscutellata, and Lu. whitmani were identified. The canine survey revealed the prevalence of 1.14% for canine visceral leishmaniasis in the Pedra 90 region, the region being considered a transmission area.

title: Ex-vivo evaluation of the three-column concept in canine thoracolumbar fractures

description: ABSTRACT Traumatic events such as a motor vehicle accident or falling from heights are very common in veterinary medicine and often lead to vertebral fracture-luxation with concomitant spinal cord injuries, mostly in the thoracolumbar spine. The purpose of this cadaveric biomechanical study was to determine the feasibility of the three-column concept in canine thoracolumbar segments with induced fractures. Eighteen Functional Spinal Units (FSU) of the thoracolumbar segments (T12-L2) were collected from 18 medium-sized adult dog cadavers and were subjected to flexion-extension and lateral bending tests so that range of motion (ROM) was recorded with a goniometer. Fractures were induced by compressive loads applied by a universal testing machine (EMIC®). After this, specimens were screened using computed tomography (CT) and the fractures were graded as affecting one, two or three columns, and divided into groups A, B, and C, respectively. Post-fracture range of motion (ROM) was compared with the previous results. Groups B and C (with fractures in two or three columns) had instability in the two axes evaluated (P&lt;0.05). The outcomes of this study support the applicability of the three-column theory to thoracolumbar spines of dogs, as the FSUs that suffered fractures in two or more columns showed axial instability.

title: Emergence of multidrug-resistant bacteria isolated from surgical site infection in dogs and cats

description: ABSTRACT Surgical site infections (SSIs) and antimicrobial resistance among pathogens causing SSI are a growing concern in veterinary hospitals. One major reason, the widespread use of antimicrobials, has led to increased incidence of SSIs. This study identified bacteria and resistance profiles to antimicrobials in the SSI cases diagnosed at the Surgical Clinic of Small Animals in the Veterinary Hospital, Federal University of Viçosa, Brazil. The main genus identified was Staphylococcus, followed by Escherichia, Enterococcus, Bacillus, Shigella, Citrobacter, Proteus, Morganella, Serratia, Enterobacter, Pseudomonas and Klebsiella were also found, but in small number. The results indicated the predominance of Gram-negative bacteria among the collected samples. Most of isolates identified were resistant to more than one of the following antimicrobials: ampicillin, tetracycline, enrofloxacin, amoxicillin/clavulanic acid and cephalotin. Of the 17 Staphylococcus sp. isolates, two (11.8%) were methicillin-resistant Staphylococcus aureus (MRSA) and 11 (64.7%) of them were methicillin-resistant Staphylococcus pseudintermedius (MRSP). There were bacterial genera identified with resistance to all tested antimicrobials in different proportions. This should alert veterinary hospitals to the emergence of multidrug-resistant bacteria and to the requirement for the revision of surgical protocols with regard to antimicrobial prophylaxis and therapy.

title: [Effects of oxygeninspired fractions and different ventilatory modalities on the age of dogs]

description: ABSTRACT The objective was to evaluate different ventilatory modalities in dogs of different ages submitted to the inspired fraction of oxygen (FiO2) of 40% and 100%. Thirty-six dogs from three age groups (GJ 0-5, GA 5-10 and GG 10-15 years) were used, without standardization of weight, gender, race and surgical procedure. They were premedicated with acepromazine and morphine (0.02 and 0.5mg/kg), induced to general anesthesia with propofol dose/effect, maintenance of the anesthetic plane with isoflurane in 1.3V% and oxygen supply according to FiO2 established for the group. The animals were submitted to 4 different ventilation modalities, spontaneous ventilation (VS), volume-cycled ventilation (VCV), pressure-cycled ventilation (VCP) and pressure-cycled ventilation with PEEP (VCPP) and remained 30 minutes in each modality. The cardiovascular parameters remained stable for all FiO2, ventilatory modalities and ages. Regarding ventilatory parameters, in FiO2 and PaCO2 of 45mmHg and 29% of shunt, in FiO2 100%, PaCO2 of 43mmHg and 13% of shunt were observed. Regarding the different ages, adult and geriatric animals presented higher values of Shunt (26 and 22%) and PaCO2 (44 and 46mmHg). It was concluded that the inspired fraction of 40% and the volume-cycled ventilatory modality were more efficient.

title: [Sequential proposal in the myelographic views for detection of spinal cord compression in dogs with cervical intervertebral disc disease]

description: ABSTRACT The aim of this study was to verify in which of the myelographic views it was possible to identify spinal cord compression in dogs with cervical intervertebral disc disease (IVDD), and to establish a sequence in which myelographic views should be obtained for this region. Four myelographic views (lateral, ventrodorsal, left oblique and right oblique) of 41 patients diagnosed with cervical IVDD were evaluated. In 40 patients (97.5%) it was possible to identify spinal cord compression by lateral view, 22 (53.6%) by the oblique view, and 11 (26.8%) by the ventrodorsal view (P&lt; 0.05). There were lateralized compressions in 22 (53.6%) patients, detected by all oblique views (100%) and by 11 (50%) of the ventrodorsal views. In 10 (24.4%) dogs, more than one compression site was observed, where the ventrodorsal view helped to decide the site in 50% of the cases and oblique in 70%. It can be concluded that all the tested myelographic views allow the identification of spinal cord compressions in dogs with cervical IVDD, the lateral view being the most relevant, followed by the oblique and ventrodorsal view, therefore establishing a sequence of myelographic views should be obtained for this region.

title: Electrophoretic analysis (sds-page) of canine urinary proteins according to the stage of chronic kidney disease

description: ABSTRACT Glomerular proteinuria is characterized by the loss of high-molecular-weight proteins (HMWPs), while tubulointerstitial proteinuria is characterized by the loss of low-molecular-weight proteins (LMWPs). The objective was to assess the molecular weight of urinary proteins (MWUP) in dogs with naturally acquired CKD and determine the proportion of HMWPs and LMWPs according to CKD stage. Twenty-eight dogs with CKD were recruited and divided into 4 groups based on serum creatinine (Cr) levels (group1: Cr&lt;1,4, n=8; group2: 1,45,0, n=5). The control group consisted of 5 healthy dogs. The MWUP was determined by SDS-PAGE. The urinary protein-to-creatinine ratio (UP/C) was used to quantitatively assess proteinuria. The electrophoresis pattern revealed a proportionally greater loss of HMWPthan of LMWP in all groups with CKD and an increased loss of LMWP in group 4 (P&lt;0.05). These results suggest a predominance of glomerular injuries throughout all stages of CKD in these dogs and an increase in tubulointerstitial injury towards the end-stage of the disease. The results of the present study support the recommendation of SDS-PAGE as an effective technique for the qualitative assessment of proteinuria, as well as a method for assessing the severity and location of renal injury.

title: Caudal vena cava collapsibility index in healthy cats by ultrasonography

description: ABSTRACT The objective of this study was to calculate the collapsibility index (CI) in a group of 15 healthy adult mixed breed cats via right hepatic intercostal ultrasound view. The minimal and the maximal diameters of the caudal vena cava (CVC) were obtained during inspiration and expiration, respectively, then CI was calculated. The mean diameter of the CVC was 0.5cm. The mean CI was 28±3% and CI was not significantly associated with gender. As in human medicine, there is a growing need for less invasive monitoring in small animal practice. The CI enables the assessment of estimated volemia without the need for a central venous catheter. This is the first reported study investigating CI in cats.
