Aims: To evaluate the prognosis of horses treated surgically for open joint injuries. Methods: The medical records of horses admitted for surgical treatment of a wound in communication with a joint were reviewed. A telephone questionnaire was used for the long term evaluation. Fisher’s exact tests were used for the statistical analyses. Results: Twenty two horses were included in the study with the following distribution of lesions: 6 carpi, 6 fetlocks, 4 tibiotarsal joints, 2 proximal and 3 distal interphalangeal joints, 1 elbow. The duration of the injury before referral ranged from 3 hours to 10 days. Surgical treatment consisted of 1-3 joint lavages. Of the 22 horses, 4 were euthanatized during hospitalization and 18 were discharged. After discharge, 3 horses died due to colic, 2 were lost and 13 were still alive. The survival was not influenced by the duration of the wound. All horses with cutaneous defects less than 5 cm and all horses affected in the lower limb (below the level of the canon) were discharged. Having an affected joint proximal to the canon was significantly associated to the need of multiple surgeries (OR: 17.5; p= 0.024). Conclusions: Even if the prognosis remains guarded for open joint injuries, a long delay between injury and treatment should not be systematically associated with a bad prognosis for survival. Open joint injuries of the lower limb were associated with survival. They required less often multiple articular lavages than open joint injuries of the upper limb, warranting thus a better prognosis. [less ▲]

Alfaxalone, a synthetic neuroactive steroid, has been shown to induce smooth general anesthesia in wild and companion rabbits. The aim of the study was to test the effect of alfaxolone in experimental rabbits without concomitant oxygen supplementation.Respiratory status was assessed by measuring the duration of the post-induction apnea, the respiratory rate, the oxygen saturation of hemoglobin in the peripheral blood (SpO2) and the end-tidal CO2 (EtCO2) Cardiac function was assessed by monitoring heart rate using a pulse oximeter. The degree of anesthesia was monitored by evaluating ear and paw pinch reflex, as well as ocular signs such as nystagmus, exophtalmia and the loss of palpebral and corneal reflexes. [less ▲]

Introduction: Les kératomes, masses hyperplasiques de kératine, croissent entre la phalange distale (P3) et la paroi du sabot et provoquent des boiteries chez le cheval. La littérature comporte de nombreux rapports de cas isolés mais peu de séries cliniques. Matériel et méthodes: Les dossiers cliniques des cas de kératomes présentés depuis 2004 à la faculté de médecine vétérinaire de Liège ont été revus. Résultats: Vingt-trois kératomes ont été diagnostiqués sur 19 chevaux boiteux. Un cheval présentait 2 kératomes sur le même pied et 3 chevaux présentaient 2 kératomes sur des pieds différents. Sur les 22 pieds atteints, les lésions observées étaient: un abcès, souvent récidivant (18 cas), une déformation de la muraille (6 cas), une déviation de la ligne blanche (6 cas) et une seime (3 cas). Un kératome était situé sous la sole et 22 sous la muraille. La durée des symptômes variait de 2 semaines à 15 ans (plus d'un an sur 12 pieds). Sur les radiographies, une lyse par compression de P3 était visible en regard de 20 kératomes. Le cheval présentant 2 kératomes sur le même pied a été euthanasié. Trois kératomes ont été traités de manière conservative. Dix-huit kératomes (chez 16 chevaux) ont été excisés chirurgicalement dont 16 par avulsion complète de muraille, 1 par avulsion partielle de muraille et 1 par curetage d'une portion de sole. Aucune complication postopératoire n'a été observée dans 7/18 cas (39%). Les complications rencontrées étaient: une granulation excessive (10 cas), une douleur importante pendant plusieurs jours (5 cas), une légère infection (4 cas), un enfoncement de P3 en regard de la zone avulsée (2 cas) et une récidive (2 cas, dont 1 a été réopéré avec succès ultérieurement). Un cheval est encore en convalescence au moment de cette étude. Le suivi à long terme d’un cheval a été perdu. Des 14 chevaux repris dans l'évaluation postopératoire, 1 a été euthanasié pour une autre raison que le kératome, 3 chevaux ont gardé une boiterie résiduelle au trot et 10 chevaux ont récupéré leur niveau d'activité. Discussion: La littérature décrit les kératomes comme rares1. Or, 21% des chevaux de cette étude (4 chevaux sur 19) présentaient plusieurs kératomes. De plus, dans 54 % des cas, les symptômes duraient depuis plus d’un an. Dès lors, il apparait que les kératomes sont sous diagnostiqués ou le sont souvent tardivement. La chronicité et l’étendue des kératomes de cette étude n’a que très rarement permis leur résection par avulsion partielle de muraille, technique de choix dont les complications postopératoires sont moindres². Un diagnostic précoce par inspection minutieuse des sabots, particulièrement en cas d’abcès de pied récidivant permettrait une excision par une technique moins invasive, qui diminuerait la convalescence et les complications postopératoires.

Background Pulsed wave (PW) Doppler echocardiography has become a routine non invasive cardiac diagnostic tool in most species. However, evaluation of intracardiac blood flow requires reference values, which are poorly documented in goats. The aim of this study was to test the repeatability, the variability, and to establish the reference values of PW measurements in healthy adult Saanen goats. Using a standardised PW Doppler echocardiographic protocol, 10 healthy adult unsedated female Saanen goats were investigated three times at one day intervals by the same observer. Mitral, tricuspid, aortic and pulmonary flows were measured from a right parasternal view, and mitral and aortic flows were also measured from a left parasternal view. The difference between left and right side measurements and the intra-observer inter-day repeatability were tested and then the reference values of PW Doppler echocardiographic parameters in healthy adult female Saanen goats were established. Results As documented in other species, all caprine PW Doppler parameters demonstrated a poor inter-day repeatability and a moderate variability. Tricuspid and pulmonary flows were best evaluated on the right side whereas mitral and aortic flows were best obtained on the left side, and reference values are reported for healthy adult Saanen goats. Conclusions PW Doppler echocardiography allows the measurement of intracardiac blood flow indices in goats. The reference values establishment will help interpreting these indices of cardiac function in clinical cardiac cases and developing animal models for human cardiology research. [less ▲]

Echocardiography has become a routine non invasive cardiac diagnostic tool in most species. Accurate measurement of cardiac dimensions requires reference values, which are poorly documented in goats. The aim of this study was to test the inter-day repeatability and to establish the reference values of two-dimensional (2D-) and time-motion (M-) mode echocardiographic variables in healthy adult Saanen goats. Six goats were investigated three times by the same observer at one day interval using a standardized 2D- and M-mode echocardiographic protocol. The intra-observer inter-day repeatability was tested using analysis of variance, calculation of the coefficient of variation and confidence intervals. A single echocardiographic examination was performed in 6 other goats, and values obtained in the 12 goats were used to establish the 2D- and M-mode echocardiographic reference values in healthy adult female Saanen goats. Statistical analysis revealed a good inter-day repeatability of the echocardiographic cardiac measurements. Echocardiographic reference values obtained in healthy adult Saanen goats seemed slightly higher than those reported in healthy Swedish domestic goats and were similar to those reported in healthy adult sheep.

The objective of this study was to compare the sedative and peripheral hemodynamic effects of acepromazine (ACP) and promethazine (PTZ) in the standing healthy horse. Nine healthy Warmblood horses randomly received either intravenous ACP at 0.1 mg/kg or PTZ at 0.1, 0.2, and 0.3 mg/kg. A sedation score based on clinical examination was recorded, and systolic arterial blood pressure was noninvasively evaluated using a Doppler flow detector at the tail, just before and every 15 minutes until 60 minutes after drug injection. Hemodynamics of the median artery of the left forelimb was studied using Doppler ultrasonography just before and 45 minutes after injection of the drug, which allowed calculation of surface (SURF), diameter (DIAM), and circumference (CIRC) of the vessel and peak systolic velocity (PSV), end diastolic velocity (EDV), mean velocity (MV), volumetric flow (VF), and resistivity index (RI) of the blood flow. Regardless of the dose used, PTZ had lesser sedative and hypotensive effects than ACP at 0.1 mg/kg and did not induce significant variations in SURF, DIAM, CIRC, PSV, EDV, MV, VF, and RI of the studied standing horses. Conversely, the vasodilatory properties of ACP were illustrated by a significant increase in SURF, DIAM, CIRC, PSV, EDV, MV, and VF and a significant reduction of the RI. Unlike ACP, PTZ did not induce alterations on the morphology of the Doppler waveform. PTZ appears to have less sedative and peripheral vasodilator effects than ACP, thus it could be safer than ACP in patients suffering from hypotension. [less ▲]

Introduction Le défaut du septum interventriculaire ou communication interventriculaire (CIV) est l’anomalie congénitale la plus fréquente chez le cheval. Le diagnostic et le pronostic de cette pathologie sont réalisés au moyen de l’échocardiographie Doppler pulsé. Cette étude a pour but de décrire les cas observés entre 1998 et 2008 à la clinique équine de l’Université de Liège, mais aussi de déterminer leur devenir à long terme. Matériel et méthodes Sept chevaux présentant une CIV ont été présentés en clinique. Leur race, âge, sexe, symptômes, et le motif de la consultation ont été notés puis une échocardiographie Doppler pulsé a été effectuée. Un suivi téléphonique a aussi été mis en place en 2011 pour connaître leur évolution à long terme. Résultats Les 7 chevaux présentés avaient entre 1 mois et 11 ans. Six chevaux étaient des demi-sang et le septième était un poney islandais. Tous les chevaux présentaient un souffle bilatéral holo- ou pan-systolique de grade égale ou supérieur à 5/6, plus intense à droite en région tricuspide. Cinq chevaux étaient référés pour souffle sans symptôme associé tandis que les 2 autres présentaient des œdèmes, de l’intolérance à l’effort et de la dyspnée. A l’échocardiographie, toutes les CIV étaient localisées à la base du septum dans sa partie membraneuse. Cependant, pour le premier cheval, examiné en 1998, une communication atypique entre le ventricule gauche (VG) et l’oreillette droite (OD) fut observée. La taille des CIV variait entre 0,5 et 6,6cm et la vitesse du shunt, toujours dirigé de gauche à droite, était comprise entre 2,5 et 5,5 m/s. Le premier cheval, référé en clinique en 1998, était en insuffisance cardiaque très sévère et présentait une dilatation des 2 ventricules et des 2 oreillettes, une fibrillation auriculaire et une insuffisance mitrale et tricuspide sévères. Le 2ème cheval avec des signes d’insuffisance cardiaque était un poulain d’1 mois avec une CIV de grande taille (2,6 cm) associé à un début de dilatation du ventricule droit sans autre anomalie cardiaque. Enfin, 3 des 5 chevaux asymptomatiques présentaient différentes insuffisances valvulaires mais seulement légères à modérées et une sténose pulmonaire a été observé chez l’un d’entre eux. Discussion et conclusions Les résultats de cette étude sont en accord avec la littérature. Les CIV sont associées à un souffle bilatéral holo- ou pan-systolique important et sont majoritairement localisés dans la partie membraneuse du septum. Une vitesse élevée du shunt est associée à une CIV de petite taille et à un pronostic vital et sportif bon. Par contre, en cas de CIV associé à d’autres anomalies graves comme des insuffisances valvulaires sévères, le pronostic est sombre. [less ▲]

Background: Despite the recent advances in this area, colic remains a major cause of morbidity and death in horses. Neutrophilic activation and degranulation may play a key role in the postoperative complications. Activated neutrophils release enzymes like proteases and myeloperoxidase (MPO). MPO concentrations in plasma and tissue are considered as a marker of neutrophil activation. (McConnico et al. 1999; Hoy et al. 2002). When freed in the tissue, active MPO is able to oxidize, nitrate and chlorate most organic molecules (Klebanoff 2005). Objectives: The aim of this study was 1) to determine the time trends of blood leukocyte and neutrophil counts as well as of plasmatic MPO concentrations in the perioperative period of horses undergoing colic surgery and 2) to relate these time trends to the location of the pathology, the severity of postoperative complications and to the outcome of the patients. Methods: Fifty two horses undergoing colic surgery at the Equine Teaching Hospital of the University of Liege were included in this study. The location of the predominant lesion of the intestine, the severity of the postoperative complications and the outcome were recorded for each horse. Total leukocyte and neutrophil counts were performed in all of the horses while plasmatic myeloperoxidase levels were determined in 16 of them. The blood samplings were realized before and during the surgery (after correction of the intestinal lesion), during the recovery and every 4 hours during the first 4 days (from day 0 until day 4) and then every 12 hours until day 6 (150th hour after the first blood sampling) or until euthanasia. Hematologic analyses were performed at the time of sampling by use of the Medonic CA 530 (Menarini, Zaventem, Belgium). The blood was then centrifuged and the plasma was aliquoted and frozen at -20° C until assayed. MPO was assayed with a specific enzyme-linked immunosorbent assay (Equine MPO-ELISA kit, BiopTis, Liège, Belgium). A mixed model was used to analyze the time trends of leukocytes, neutrophils and MPO. All computations were done with the SAS (Statistical Analysis System) procedure Proc Mixed, with Satterthwaite degrees of freedom. The significance level was set at p=0.05. Results: The main pathology was found in the large intestine in 30 horses (58%) and the small intestine in 22 horses (42%). Forty horses (77%) survived to discharge from the clinic. Twelve horses were euthanized during the postoperative period. Their survival time varied from 0.5 day to 20 days with a mean of 7.8 days. Twenty-two horses (42%) showed none or mild complications, 12 horses (23%) showed moderate complications and 18 horses (35%) suffered from severe complications. Time trends for leukocytes and neutrophils were similar to each other (p= 0.7205) and significantly different (p< 0.0001) from the MPO time trend, which increased during the first hours, while the neutrophil time trend decreased immediately after the admission. The time trend of neutrophils was higher in large intestinal than in small intestinal pathologies and the time trend of MPO was lower in large intestinal than in small intestinal pathologies. The time trends of neutrophils were significantly different between the degrees of complications (no/mild vs moderate vs severe). For the first part of the curve, the more severe the complication, the lower is the time trend. The time trend of MPO was lower in survivors. The time trend of neutrophils in survivors was higher during the first 4 days thereafter it becomes lower than in non survivors. Conclusions: These results confirm that neutrophil counts and MPO levels undergo timely changes and that they are related to the severity of the inflammatory reaction in surgical colic cases. Knowing the kinetics of these parameters is an essential step to further determine cut-off values (with a larger group of horses) for the prognosis of horses after colic surgery.

Echocardiography has become a routine non invasive cardiac diagnostic tool in most species. Accurate measurement of cardiac dimensions requires reference values, which are poorly documented in goats. Goats are animals easy to handle with a body and heart size comparable to humans’. This makes goats an attractive candidate for the development of animal models for human cardiology research. The aim of this study was to test the repeatability and to establish the reference values of bi-dimensional (2D-), time-motion (M-) mode and pulsed wave (PW) Doppler echocardiographic variables in adult goats. Six healthy female adult Saanen goats were investigated three times by the same observer at one day interval using a standardized 2D-, M-mode and PW Doppler echocardiographic protocol. Calculation of the coefficient of variation for each variable measured within day and depending on the day allowed to evaluate their degree of variability. A single echocardiographic examination was performed in 6 other goats by the same observer, and the obtained values were added to these obtained on the third day of the 6 first goats. Then the observed mean, the standard deviation and the range of these measurements were calculated to establish the reference values of echocardiographic parameters in unsedated adult healthy female Saanen goats. Statistical analysis revealed a good inter-day repeatability of the 2D- and M-mode echocardiographic cardiac measurements, but PW Doppler parameters presented moderate to high variability, as documented in other species. Echocardiographic reference values obtained in healthy adult Saanen goats were similar to those reported in healthy adult sheep and in healthy adult humans. [less ▲]
