The medical records of 28 horses with guttural pouch mycosis were reviewed. The most commonly observed clinical signs were nasal discharge, epistaxis, dysphagia and/or cough. All 28 horses had the disease unilaterally, however, in five of them, it had spread into the contralateral pouch via the mesial septum. Three horses were treated medically, 11 horses underwent surgery and seven horses were treated both medically and surgically. Fifty percent of horses (14/28) were euthanased or died, fifty percent of horses (14/28) survived. There was no significant correlation between treatment method (medical, surgical, combination) and survival rate. The most common reason for euthanasia was dysphagia due to pharyngeal dysfunction. There was a highly significant correlation between the presence of dysphagia and non-survival (p=0.008).
ABSTRACT:Twelve clinical cases of cyathostomosis in horses treated at the Equine Clinic University of Veterinary and Pharmaceutical Sciences in Brno, the Czech Republic, between the years 1999 and 2008 are described in this report. Six cases (50%) were hospitalized in the period from 2007 to 2008. Eleven of them were hospitalized in the period from December to March. Only one case was admitted in June, but the clinical signs had appeared for the first time in January. All horses described in these cases were younger than six years of age. Diarrhoea as a predominant clinical sign was present in four horses and colic in four horses. One horse showed both colic and diarrhoea whilst three horses had weight loss and subcutaneous oedema. Metabolic acidosis was found in three horses, eight patients had leucocytosis. Hypoproteinemia was found in four horses, hypoalbuminemia in seven horses, hypokalemia in three horses and increased alkaline phosphatase (ALP) activity in five horses. Seven horses recovered, one horse died and four horses were euthanized.
The case of atypical myopathy (AM) in newborn Haflinger foal with clinical signs of depression and weakness appearing 6 hours after birth resulting in recumbency 12 hours after birth is described. The foal's dam was diagnosed with AM in the 6th month of gestation based on clinical signs of a myopathy, elevated serum activity of creatine kinase, metabolomic analysis and the presence of methylenecyclopropyl acetyl carnitine (MCPA‐carnitine) in the blood. At the time of delivery, the mare was grazing on a pasture near sycamore trees but was free of clinical signs of AM. Metabolomic analysis of the foal's blood revealed increased concentrations of acylcarnitines and MCPA‐carnitine consistent with metabolic profiles of blood from AM affected horses. Two theories could explain this observation (a) hypoglycin A or its metabolites accumulated in the mare's placenta with consequent transfer to fetus or (b) these compounds were secreted into mare's milk.
Summary A Warmblood foal was admitted at one day of age because of prematurity and seizures. Clinical and clinical pathology abnormalities were consistent with prematurity and suspected hypoxic seizures that responded to anti‐convulsive therapy. The foal stabilised after several days of intensive care but then developed an airway infection. Thoracic radiographs showed multiple cavitary lesions and ultrasound examination suggested intra‐cavital haemorrhage. The foal went on to develop septicaemia and was subjected to euthanasia. Post mortem examination revealed multiple bullous emphysema with haemorrhage. This disorder should be considered in the differential diagnosis of foals having air‐fluid filled cavities on thoracic radiographs.
Summary Two horses suffering from a cough, purulent foul smelling nasal discharge, inappetence and intermittent fever were hospitalised at the Equine Clinic in Brno from 2008–2010. A diagnosis was made on the basis of endoscopic examination which revealed a foreign body (thorny branchlet) in the right caudal lobe bronchus in both horses. Pleuropneumonia developed as a complication in both horses. Following endoscopic extraction of the foreign bodies, both horses were treated using antibiotics and drainage of the pleural cavity. One of the patients recovered, the second was subjected to euthanasia at the request of the owner.
