Author(s): 
J. DECLERCQ, G. VERCAUTEREN
Abstract: 
In this paper, necrotizing eosinophilic dermatitis with an acute onset and a rapidly progressiveclinical course is reported in three dogs. Early skin lesions were characterized by intensely pruritic,erythematous and firm intact papules and plaques. The lesions enlarged and evolved quickly intocoalescing nodular target shaped lesions with central exudation, ulceration and necrosis. Thelesion distribution pattern was mainly the neck and the dorsolateral trunk. Oral involvementwas observed in one dog. The histopathology was characterized by eosinophilic dermatitis andpanniculitis targeting dermal and subcutaneous blood vessels with secondary involvement ofhair follicles. While causation remained unproven in these cases, a hypersensitivity reaction tomedications or other foreign antigens was suspected.

Title: 
Surgical site infections despite perioperative antimicrobial therapy in two dogs
Author(s): 
A. LYSSENS, N. DEVRIENDT, E. STOCK, T. ROGGEMAN, H. DE ROOSTER
Abstract: 
Surgical site infections (SSI) are common complications with a prevalence of 0.8 to 18%.Many risk factors, such as patient, environmental and treatment factors can contribute to thedevelopment of SSI. Two dogs that developed a SSI after forelimb amputation are discussed. Thefirst dog was presented with an open comminuted intra-articular fracture of the right elbow. Thesecond dog was diagnosed with a soft-tissue sarcoma at the right elbow. Perioperative cefazolinwas administered in both patients. Only in the first patient, antimicrobial therapy was continuedin the postoperative period. Both dogs developed an SSI within four to five days postoperatively.Yet, prophylactic antimicrobials can help to prevent SSI, provided that the correct antimicrobialis used at the correct dose, at the right time and given IV. Factors, such as hypothermia, violatingthe Halsted’s principles and the number of people present in the theater may increase therisk of SSI. Besides the meticulous use of antimicrobials, perioperative management is thus alsoimportant in SSI prevention.

Title: 
Supraventricular tachycardia with isorhythmic atrioventricular dissociation in a Labrador retriever
Author(s): 
A. VAN LOON, V. LIEKENS, D. BINST, D. PAEPE, B. HOUDELLIER, P. SMETS
Abstract: 
A neutered, seven-year-old, female Labrador retriever was presented with complaints of tachypnea,gagging and abdominal distension. A left apical systolic murmur with an intensity of 3/6, tachycardia,weak femoral pulses and positive undulation were observed on physical examination. After echocardiographicand electrocardiographic examination, dilated cardiomyopathy (primary or secundary) andsupraventricular tachycardia were diagnosed. At a later control visit, after initiation of treatment withdigoxin, electrocardiography revealed isorhythmic atrioventricular dissociation (IAVD) and poor controlof the SVT. After transition to diltiazem, the tachycardia was well-controlled. A full recovery ofthe heart was observed on echocardiographic examination. Twenty-four months later, the dog showedno more cardiac signs. In this case report, a rare arrhythmia, i.e. IAVD in combination with SVT isdescribed. It shows the importance of SVT as a reversible cause of a DCM-like phenotype on echocardiography.

Title: 
Intra-abdominal bleeding in a horse: not always of traumatic origin
Author(s): 
L. DE LANGE, A. DUFOURNI, L. LEFÈRE, L. SONCK, G. VAN LOON
Abstract: 
A nine-year-old warmblood mare was presented with clinical signs of mild colic and fever. Onpercutaneous ultrasound of the abdomen, a mass was identified on the left side of the abdomenbetween the spleen and the stomach. During examination the following day, intra-abdominalblood was observed. On rectal examination, a mass was palpated in the pelvis. The presumptivediagnosis of hematoma with intra-abdominal bleeding was made. On consecutive ultrasoundsand radiographs, the mass evolved in shape and other masses were identified in the liver and thelungs. No change was noticed in the pelvic mass. Cytology and histology of a tru-cut liver biopsyrevealed abnormal, most likely neoplastic cells, whereas cytology of the abdominal and thoracicfluid did not reveal any neoplastic cells. Due to the presence of several rapidly growing masses,a neoplastic process was most likely. Because of the malignant character of the disease and thepersistence of the clinical signs, euthanasia was suggested but refused by the owner. Supportivetreatment was instituted. Initially, the general condition remained stable, after which the horsesuddenly collapsed and died. Post-mortem examination revealed a primary neoplasm located inthe pelvic cavity, as well as multiple disseminated masses within several tissues. The mass foundin the liver had ruptured with loss of probably 50 liters hemorrhagic fluid within the abdominalcavity. Based on gross pathology, cytological and histological findings, a hemangiosarcoma wassuspected. This diagnosis was confirmed using immunohistochemistry for von Willebrand factor.In this case report, the importance of differentiating hematoma from hemangiosarcoma in thehorse is highlighted.

Title: 
Vacuum phenomenon associated with triple cervical vertebral arch and ligamentum flavum anomaly resulting in severe stenotic myelopathy in a dog
Author(s): 
S. VERMEIRE, V. RONDAHL, M. RAPP
Abstract: 
A six-year-old American Staffordshire terrier with proprioceptive deficits of the right thoracicand pelvic limb was referred for further work-up. Cervical computed tomography (CT)and magnetic resonance imaging (MRI) revealed a triple cervical canal stenosis with dorsal spinalcord compression and concomitant compressive myelopathy caused by vertebral arch andligamentum flavum proliferation and hypertrophy. Vacuum phenomena were noticed within theligamentum flavum tissue, a previously unreported location for vacuum phenomena, which areprimarily reported within degenerative joints and intervertebral discs. Decompressive surgeryand rehabilitation resulted in a complete clinical recovery.

Title: 
Spontaneous realigning of a displaced equine premolar post extraction of an adjacent supernumerary tooth – two cases
Author(s): 
E. POLLARIS, K. VANDERPERREN, G.A.M. DE PAUW, L. VLAMINCK
Abstract: 
Two horses were presented with problems during ridden exercise due to a firm, sensitiveswelling at the level of the cheek adjacent to an upper Triadan 06. Oral, radiographic andcomputed tomographic examinations (n=1) identified the presence of a palatal supernumerarytooth being the causing factor of a buccally displaced 06. In both cases, the supernumerarytooth was extracted on the standing sedated horse. A couple of months following extraction,the buccally displaced tooth had spontaneously moved into a more physiological position dueto orthodontic forces of the cheek and masticatory forces. Both horses uneventfully returned toridden work without further problems.

Title: 
Peri-anesthetic approach of heat stroke in a dog with laryngeal paralysis
Author(s): 
N.C. BURGER, C. GADEYNE, B. VAN GOETHEM, E. STOCK, I. POLIS
Abstract: 
In this case report, a seven-year-old, male, castrated Landseer presented with chronic respiratorydistress, occasional coughing, dysphonia and exercise intolerance is described. The stresscaused by transportation and the physical examination rendered the dog severely dyspneic andcyanotic. At that moment, the core body temperature was increased up to 42.5 °C. Based on theclinical signs, laryngeal paralysis causing heat stroke was the most likely diagnosis. The dog wasanesthetized and intensive temperature control methods, like active cooling and fluid therapy,were applied. As soon as the dog was cardiovascularly stable, emergency treatment for laryngealparalysis was performed. As a result of timely intervention, the dog recovered completely withoutany persisting complications.

Author(s): 
J. DECLERCQ
Abstract: 
Neutrophilic and ulcerative dermatitis is reported in a mixed breed dog. The condition wasconsidered to be an atypical case of pyoderma gangrenosum. Clinically, it had a more superficialulceration, a more pronounced pustular component and lacked the characteristic cutaneous painand tenderness of the lesions. The diagnosis of pyoderma gangrenosum was made as a diagnosisof exclusion. The dog showed an excellent response to treatment with ciclosporin (Cyclavance,Virbac, Leuven, Belgium).
