Suspected venous air embolism in a Finnhorse

Vascular air embolism (VAE) is the entrainment of air from the operative field or other communication with the environment into the venous or arterial vasculature, producing systemic effects. The horse described in this report, after having been discovered to have dislodged the extension set from the jugular vein catheter, demonstrated clinical signs considered most likely to have resulted from a VAE, and represents a case of primarily neurological signs resolving spontaneously. Emphasis is given to the prevention and prompt recognition of this event and to the use of all available tools in the management of cardiovascular complications.     

Temporohyoid osteoarthropathy in the horse

Temporohyoid osteoarthropathy (THO) is a well‐recognised clinical entity in horses. Temporohyoid osteoarthropathy is characterised by progressive osseous proliferation of the proximal portion of the stylohyoid and petrous temporal bones, and is generally described as a disease of middle‐aged horses. More recent reports also attribute a variety of clinical syndromes in young horses to THO, requiring a diversification of approaches to confirm the diagnosis and its significance, and to guide conservative and surgical treatment options. This commentary will review the purported aetiology, clinical syndromes, available diagnostic tests and treatment options of equine THO.     

Retrospective study of neurological signs and management of seven English horses with temporohyoid osteoarthropathy

This retrospective study summarises the case details, presenting signs, management and outcome in cases of temporohyoid osteoarthropathy (THO) and describes the findings of diagnostic imaging modalities. The condition appears to be relatively rare in Europe and the objective of this study is to make clinicians aware that THO can have a range of various neurological and clinical presentations. The records of 2 referral equine practices in England were reviewed and 7 horses with THO diagnosed on guttural pouch endoscopy indentified. The clinical and neurological signs, diagnostic procedures, treatment and outcomes were reviewed. Although small, this group is the largest case series of THO from Europe. One horse was a yearling, whereas THO is generally considered usually to affect middle aged and older horses. Computed tomography was used to confirm the diagnosis and demonstrated stylohyoid bone fractures in 2 cases while there was mild increased radionuclide uptake in one of 2 cases undergoing nuclear scintigraphy. Treatment is still controversial, although ceratohyoidectomy led to complete resolution of signs in 2 of 5 cases thus treated and improvement in the other 3. One horse with mild signs treated with antimicrobials and nonsteroidal anti‐inflammatory drugs made a full recovery while another, presented with head shaking and managed with a phased exercise programme, improved but did not resolve completely.     

Polyglandular deficiency syndrome in a boxer dog: Thyroid hormone and glucocorticoid deficiency

Summary

Primary hypothyroidism and partial primary adrenocortical deficiency (isolated glucocorticoid deficiency) were diagnosed in an 8‐year‐old spayed female boxer dog, presented because of progressive symmetrical truncal alopecia, lethargy, and intolerance to cold. The diagnosis was based upon the combination of low, non‐TSH‐responsive concentrations of plasma thyroxine and low urinary excretion of corticoids together with high plasma concentrations of ACTH. Normal suppressibility of ACTH concentrations by a low dose of dexamethasone indicated an intact feedback system. Plasma growth hormone levels were elevated, most probably because somatostatin release was depressed by the glucocorticoid deficiency.

The dog improved during oral replacement therapy with thyroxine until death ensued after 9 months as a result of intercurrent disease. Autopsy revealed thyroid atrophy and lymphocytic adrenalitis with complete destruction of the zona fasciculata and zona reticularis of the adrenal cortex.

The combination of primary hypothyroidism and primary adrenocortical deficiency in this dog is identical to the entity known as type II polyglandular autoimmunity or Schmidt's syndrome in humans. The adrenocortical insufficiency remained confined to glucocorticoid deficiency during the observation period; on no occasion did electrolyte concentrations in the plasma reach values suggestive of mineralocorticoid deficiency.     

Antemortem Diagnosis of CDV Infection by RT-PCR in Distemper Dogs with Neurological Deficits without the Typical Clinical Presentation

In dogs with neurological disturbances without myoclonus and extraneural signs, the clinical diagnosis of distemper is difficult perform. Considering the great infectious potential of the disease, the possibility of carrying out an antemortem diagnosis of distemper is important, particularly in hospitalized patients with neurological disease. The present study was carried out to evaluate RT-PCR for antemortem CDV detection in hospitalized dogs with neurological disturbances without the typical findings of distemper. We investigated five dogs with canine distemper virus (CDV) encephalomyelitis, in which the clinical diagnosis was not performed owing to the absence of characteristic signs of the disease, such as myoclonus and systemic signs. We observed an apparent high sensitivity of RT-PCR in urine samples for detection of CDV: four out of five urine samples were RT-PCR positive. The results of the present study suggest that urine is a good biological sample for antemortem CDV detection by RT-PCR in dogs with distemper encephalomyelitis in which the clinical diagnosis is likely to be difficult owing to the absence of suggestive distemper signs. The use of two different body fluids (urine and CSF) may increase the RT-PCR sensitivity for antemortem diagnosis of distemper in such cases.

Putative intestinal hyperammonaemia in horses: 36 cases

Reasons for performing the study: Intestinal hyperammonaemia (HA) has been infrequently reported in individual horses; however, there have been no studies describing clinical and laboratory data as well as short‐ and long‐term outcome in a larger number of cases. Objectives: To describe clinical and laboratory data and short‐ and long‐term outcome in a large group of horses with intestinal HA. Methods: Multi‐centred, retrospective study; case records of horses with HA were reviewed and any horse with a clinical or post mortem diagnosis of intestinal HA was included. Hyperammonaemia was defined as a blood ammonium (NH₄⁺) concentration ≥60 µmol/l and horses with a diagnosis of primary hepatic disease were excluded. Relevant data were recorded and, if appropriate, data from survivors were compared to nonsurvivors to identify potential prognostic indicators. Results: Thirty‐six cases, 26 mature horses and 10 foals with intestinal HA were identified. Case histories included diarrhoea, colic and neurological signs and the most common clinical diagnosis was colitis and/or enteritis. The most common clinical and laboratory abnormalities included tachycardia, increased packed cell volume, hyperlactataemia and hyperglycaemia. Fourteen horses (39%) survived to discharge; NH₄⁺ concentration on admission was the only parameter significantly associated with survival. All surviving horses and foals for which follow‐up information was available recovered completely and returned to their intended use without further complications. Conclusions and potential relevance: Intestinal HA occurs in mature horses and foals and can be associated with severe clinical and laboratory abnormalities; further studies are required to investigate predisposing factors and delineate possible differences in aetiologies.
