A Pilot Study on the Efficacy of a Single Intra-Articular Administration of Triamcinolone Acetonide, Hyaluronan, and a Combination of Both for Clinical Management of Osteoarthritis in Police Working Dogs.

To describe and compare the use and effectiveness of a single intra-articular injection (IA) of triamcinolone acetonide (TA), hyaluronan (HA), and a combination of both (TA+HA) in police working dogs with natural occurring hip osteoarthritis (OA). Prospective, randomized, single-blinded study. Thirty animals with naturally occurring hip OA.

Thermographic imaging of police working dogs with bilateral naturally occurring hip osteoarthritis.

Background: Digital thermal imaging is a physiologic, non-invasive, contactless, and non-radiating diagnostic tool that can assess a wide range of musculoskeletal conditions, including hip osteoarthritis (HOA). Fifty police working dogs were evaluated to compare the dorsoventral (DV) and lateral (LT) thermographic images in dogs with naturally occurring bilateral HOA. A DV, and left and right lateral LT images were obtained for each animal in six different moments.

Clinical and diagnostic imaging findings in police working dogs referred for hip osteoarthritis.

Background: Osteoarthritis (OA) is the most commonly diagnosed joint disease in veterinary medicine, with at least 80% of the cases of lameness and joint diseases in companion animals being classified as OA. Sporting and working animals are more predisposed to develop OA since they are exposed to chronic fatigue injuries, leading to bone and muscular tissue damage and failure, resulting in clinical signs. To characterize the clinical signs and diagnostic findings of Police working dogs presenting with bilateral hip OA at the time of diagnosis.

A report on the use of a single intra-articular administration of autologous platelet therapy in a naturally occurring canine osteoarthritis model - a preliminary study.

Background: Osteoarthritis (OA) represents a significant burden to societies, as it affects quality of life, performance and poses a large healthcare cost. We aimed to describe the use of a single intra-articular (IA) injection of an autologous platelet therapy in the management of osteoarthritis (OA) in a naturally occurring canine model.

Methods: Fifteen police working dogs with bilateral hip OA were treated with 3 ml of platelet concentrate per hip joint, produced with the V-PET kit.

Using Bronson Equation to Accurately Predict the Dog Brain Weight Based on Body Weight Parameter.

The study used 69 brains ( = 69) from adult dog cadavers, divided by their skull type into three groups, brachi (B), dolicho (D) and mesaticephalic (M) ( = 23 each), and aimed: (1) to determine whether the Bronson equation may be applied, without reservation, to estimate brain weight (BW) in brachy (B), dolicho (D), and mesaticephalic (M) dog breeds; and (2) to evaluate which breeds are more closely related to each other in an evolutionary scenario. All subjects were identified by sex, age, breed, and body weight (bw). An oscillating saw was used for a circumferential craniotomy to open the skulls; the brains were removed and weighed using a digital scale.

A Pilot Study Exploring the Plasma Potassium Variation in Dogs Undergoing Steroid Therapy and Its Clinical Importance.

In most situations in veterinary medicine, glucocorticoids are the drugs of choice used, that is, to reduce the inflammatory response or limit an inappropriate immune response. Their use in long-term therapy may cause side effects that may weaken the patient. The aim of the study was to evaluate possible variations in the plasma potassium concentrations and their clinical relevance in dogs undergoing steroid therapy with methylprednisolone in anti-inflammatory doses.

Insight of Dogs' Inner Mandible Anatomy using Mathematical Models.

This study was performed in a sample of 20 dogs (n = 20) and aimed to: (1) characterize the mandible height (Mh), mandibular canal height (MCh) and distance between the inter-dental alveolar margin and the mandibular canal (dIAM-MC) dimensions, and (2) to develop mathematical models that express the insight's mandible anatomy of those important mandible structural elements allowing the prediction of their dimensions using physical parameters such as patient body weight (Wg) and the canine tooth width at the free gingival margin level-(wCGM). Lateral-view X-rays of both sides of the skull were taken for all the individuals. Three mathematical prediction models were developed to calculate Mh, MCh and dIAM-MC.

Relationship Between Gender, Age, and Weight and the Serum Ionized Calcium Variations in Dog Periodontal Disease Evolution.

To analyze the relationships between gender, age, weight, and variations in the levels of serum ionized calcium ([iCa(2+)]) during periodontal disease (PD) evolution. In this study, dogs (n = 50) were divided into 5 groups according to the stage of PD: G0 (no PD), G1 (gingivitis), G2 (initial periodontitis), G3 (moderate periodontitis), and G4 (severe periodontitis). Statistically significant correlations were observed between age, [iCa(2+)] levels, and PD stage.

Serum Ionized Calcium Quantification for Staging Canine Periodontal Disease: A Preliminary Study.

Periodontal diseases (PD) are infectious, inflammatory, progressive diseases of the oral cavity affecting people and dogs. PD takes 2 forms: gingivitis and periodontitis. Diagnosing or staging PD can be achieved only with dental x-rays and periodontal probing, both of which require the use of general anesthesia in dogs.

Morphological Variations in the Transverse Venous Sinus Anatomy of Dogs and its Relationship to Skull Landmarks.

We characterized the anatomical morphology of the transverse venous sinus (TVS) of 69 canine adult cadavers belonging to three groups: brachycephalic (B), dolichocephalic (D) and mesaticephalic (M). In addition, we outlined its path over the skull using five classic human craniometric points (CPs): the asterion (ast), the bregma (b), the glabella (g), the stephanion (st) and the pterion (pt). The study aimed to establish anatomical differences in the TVS between groups and in the relationship between the TVS and skull.

Serum and synovial fluid C-reactive protein level variations in dogs with degenerative joint disease and their relationships with physiological parameters.

Degenerative joint disease (DJD) is a progressive, chronic joint disease with an inflammatory component promoting an acute phase protein (APP) response. C-reactive protein (CRP) is one of the most important APPs, used as an inflammation marker in human, but not veterinary medicine. The study was developed in a sample of 48 dogs (n = 48) with DJD and aimed to: 1) identify and quantify the synovial fluid CRP (SFCRP) in these specimens using a validated ELISA test for serum CRP (SCRP) detection and quantification; and 2) to study the possible relationship between SCRP and SFCRP levels variations in DJD patients evaluating the influence of some physical parameters such as gender, body weight, pain level, DJD grade, and the physical activity (PA) of the patients.

Longitudinal Cerebral Fissure Anatomy Variations in Brachy-, Dolicho- and Mesaticephalic Dogs and Their Importance to Brain Surgery.

The study used a sample of 69 formalin-fixed brains from adult dog cadavers (n = 69) and aimed (1) to characterize the longitudinal cerebral fissure (LCF) anatomy in brachy-(B), dolicho-(D) and mesaticephalic-(M) dogs and their potential differences, and (2) to establish cranioencephalic relationships between the LCF and five classical craniometric points(cp): asterion(ast), bregma(b), stephanion(st), glabella(g), and pterion(pt). Anatomical records were collected using a digital caliper, and for statistical analysis P-values < 0.05 were considered significant.

Anatomical Variations in the Pseudosylvian Fissure Morphology of Brachy-, Dolicho-, and Mesaticephalic Dogs.

The purpose of the study is the following: (1) to anatomically characterize the right and the left pseudosylvian fissure (Psf) morphology; (2) to determine Psf variations between both hemispheres and between the three considered groups; and (3) to understand how these variations may influence brain surgery for dogs. Also we sought to determine whether there are any potential differences between brachy- (B), dolicho- (D), and mesaticephalic (M) dogs. The present study considered 138 brain hemispheres (N = 138) from 69 adult dog cadavers and used bregma craniometric point (b- the junction of coronal and sagittal cranial vault sutures) to characterize the Psf location on the superolateral brain surface.
