A case of angiokeratoma

Angiokeratoma is described by various authors as a rare variant of the hemangioma in the dog, characterized by a vascular component, like all types of vascular neoplasms, but also by an epithelial component. A case of angiokeratoma is described in a male 8-year-old dog. The tumor was located in heavily pigmented skin on the anterior surface of the front limb and not in the more usual previously described locations, eyelid and conjunctiva. Microscopic examination revealed a well-circumscribed mass with irregular hyperplasia of the epidermis and dilated vascular spaces filled with blood in the superficial dermis.     

Type III hemifacial microsomia in a kitten

The case described herein presented with craniofacial malformations resembling hemifacial microsomia (HFM), a congenital disorder described in humans. To our knowledge, this is the first reported case of HFM in a domestic cat.     

Darier's sign associated with a cutaneous mast cell tumour in a cat with multiple neoplasms

A cutaneous mast cell tumour associated with Darier's sign in a cat with multiple neoplasms is described. A 14-year-old cat with multiple neoplasms, one of which was a mast cell tumour developed marked subcutaneous oedema and erythema following palpation. The phenomenon is similar to Darier's sign described in people with mast cell tumours. The pathology of the Darier's sign is discussed.     

Spontaneous resorption of a diabetic cataract in a geriatric dog

Spontaneous cataract resorption is described in a geriatric cocker spaniel with a four-month history of diabetes mellitus. Resorption progressed to such a degree that vision was restored in that eye and almost all the cataract material disappeared. This is not common in geriatric dogs despite having been described with relative frequency in young animals with hereditary cataracts.     

Thyroid hyperplasia and musculoskeletal deformity in a standardbred filly in Ontario

Thyroid hyperplasia and musculoskeletal deformity, described in foals in western Canada, has not been recognized as a common cause of neonatal foal mortality in Ontario. A case is reported from Ontario, with clinical and histopathological findings consistent with the syndrome described in western Canada.     

The use of intraluminal stents for tracheal collapse in two horses: Case management and long‐term treatment

Tracheal collapse is an uncommon clinical disorder in horses but when present can be difficult to correct. Various medical and surgical procedures to correct tracheal collapse have been described in horses with variable success. Recently, the use of an intraluminal stent has been described as a treatment for tracheal collapse in a miniature horse. The long‐term management, utilising intraluminal stents, in 2 miniature horses with tracheal collapse is presented here. In particular, various complications as a result of intraluminal stent placement are described, the most persistent being the formation of granulation tissue at various regions of the stents. Multiple methods of combating granulation tissue in this situation also are discussed.     

A case of central diabetes insipidus in the cat: diagnosis and treatment

A case of diabetes insipidus is described in a two-year-old entire male short-haired domestic cat. The clinical signs included a marked polyuria associated with secondary polydipsia and a urine specific gravity of 1–005. Diagnosis was confirmed by water deprivation test and response to desmopressin. Treatment with chlorothiazide diuretics is also described.     

Haemophilia A (Factor VIII deficiency) in the cat

A case of haemophilia A (classical haemophilia, factor VIII deficiency) in a cat is described. The cat presented with persistent bleeding from an oral wound, and protracted haemorrhage after castration. The diagnosis and management of this case is described. Subsequent investigation of the dam and a recent litter identified a further affected male kitten.     

Juvenile nephropathy in a Weimaraner dog

A case of juvenlle nephropathy In a two-year-old Welmaraner bitch Is reported. Although juvenlle nephropathy has been described in several breeds of dogs, this is the first report In a Welmaraner. Clinical aspects, blood analysis, renal pathology and extrarenal changes are described. The renal changes consisted of tubular as well as glomerular lesions, similar to those described in the miniature schnauzer. The main extrarenal lesion was degeneration and necrosis of subendocardial myocytes in the left atrial wail associated with an inflammatory reaction and focal necrotising arteritis.     

Cardioversion of atrial fibrillation in a dog with structural heart disease using an esophageal-right atrial lead configuration

Atrial fibrillation is a common arrhythmia in dogs with structural cardiac disease and can result in significant clinical signs. Several methods of electrical cardioversion of atrial fibrillation have been described. Biphasic transthoracic cardioversion of atrial fibrillation in dogs with naturally occurring heart disease has been described in veterinary medicine and has been shown to be highly successful. In humans and research animals intracardiac and transesophageal cardioversion of atrial fibrillation has been described as an alternative to transthoracic cardioversion. While transesophageal cardioversion is very successful in humans and research animals, this technique has not been previously described in a clinical patient with naturally occurring heart disease in veterinary medicine. This report describes the use of transesophageal cardioversion in a dog with atrial fibrillation and structural cardiac disease. Cardioversion was unsuccessful using two electrodes positioned within the esophagus. Cardioversion of atrial fibrillation to normal sinus rhythm was successfully achieved and maintained using one electrode positioned within the esophagus and one electrode positioned within the right atrium using a synchronized monophasic shock of 50 J.     

Novel perineal approach for repair of a urethrorectal fistula in a bulldog

A urethrorectal fistula was diagnosed in a 10-week-old, intact male bulldog, presented with a history of urine dribbling from his anus. The fistula was ligated using a novel perineal approach, resulting in resolution of clinical signs. The described procedure is simpler and less invasive than previously described repairs.     

Dermatosis associated with Listrophorus gibbus in the rabbit

A dermatosis associated with Listrophorus gibbus, a pelage mite, is described in the rabbit. The case details of four domestic rabbits are described including diagnostic investigations, treatment, and successful recovery.     

Protein-Losing Enteropathy in a Dog

Abstract— —A protein-losing enteropathy in a dog is described. There was a history of chronic gastrointestinal upset and examination revealed hypoproteinaemic oedema and ascites. Antemortem laboratory findings indicated a protein-losing enteropathy and these, together with the results of clinical and necropsy examination, are described.     

IMAGING DIAGNOSIS—TRACHEOBRONCHIAL ZYGOMYCOSIS IN A CAT

Tracheobronchial zygomycosis is described in a cat with acute dyspnea. Zygomycetes are an uncommon opportunistic group of pathogens, and few examples have been described in feline patients. Radiographic, ultrasonographic, and computed tomography imaging allowed identification of tracheobronchial masses, with intraluminal and peribronchial involvement. Surgical removal was impossible and antifungal chemotherapy was ineffective. Feline zygomycosis is a serious condition that should be considered when tracheobronchial masses are identified.     

Hereditary cataract in the German Shepherd Dog

Primary hereditary cataract is recorded and described in the German Shepherd Dog in the United Kingdom. The cataract is not congenital, it is bilateral and progressive to a certain point and is unassociated with any other ocular abnormality. It is due to an autosomal, recessive gene. The cataract is compared to that described by von Hippel in Germany in 1930 which was congenital and non-progressive and due to a dominant gene. The two types of cataract are therefore dissimilar.     

A case of unilateral pelvic limb adactyly in a puppy dog

A case of unilateral hindlimb adactyly is described in a 3-month-old female Pointer dog. Clinical and radiographic findings are described. Adactyly or transverse hemimelia is a rare condition in most animal species. In dogs, this condition has been reported only three times as a deformity of the forelimb. To the authors' knowledge, the congenital pelvic limb deformity described here is the first case documented in a dog.     

Diplococcus pneumonia Type 16 in Laboratory Rats

An acute respiratory disease in a colony of Wistar-derived rats is described. The infection, due to Diplococcus pneumoniae type 16, has apparently not been described previously in the rat. Rigid sanitary measures and treatment with penicillin were effective in controlling the disease.     

Chronic eosinophilic keratitis in the cat

A special form of keratitis in the cat is described on the basis of 8 clinical cases. The disease has been known in the United States and the United Kingdom for some time, however, it has, to our knowledge, never been described in Switzerland. This keratitis is characterized by chronicity and infiltration of the cornea by mast cells and eosinophils. It is usually an unilateral and painless condition. We describe the clinical features and diagnostic examinations of the disease. Cytology of a corneal scraping is usually diagnostic. As in the cases described in the literature the cats were successfully treated with oral megestrol acetate. The aetiology of the disease is unknown.     

Endoscopy in birds

Endoscopic examination is described as a valuable diagnostic method in birds. In the introduction, reference is made to the literature on this subject. Apart from the classical approaches, alternative sites to enter the thoraco-abdominal cavity in birds are discussed. The basic equipment for endoscopy in birds is described and a new biopsy forceps which makes a secondary puncture redundant is introduced. After a discussion of the indications and complications, the value of the endoscopic examination is compared with other diagnostic methods for the diagnosis of avian tuberculosis in birds.     

GNATHOSTOMIASIS IN THREE CATS

SUMMARY A fatal infection with Gnathostoma spinigerum causing a perforated stomach is described in a 3-year-old cat. In a second debilitated case a small serosal perforation was found on a gastric lesion, while a third cat in good condition is described with a well developed stomach lesion but without perforation. Histopathological changes in the stomach were found in the submucosa and consisted of marked proliferation of fibrous tissue containing foci of inflammatory cells, necrotic tracts and a cavity in which the adult nematodes were found.
