Anatomic, tomographic and sonographic study of podotrochlear apparatus of adult horses
<p></p><p>ABSTRACT The navicular syndrome is a condition involving the podotrochlear apparatus and represents one of the most common causes of forelimb lameness in horses. Therefore, further study of this region is of interest when it comes to diagnosis and treatment of lameness in horses. The aim of this study was to demonstrate the differences between the imaging findings of ultrasonography and computed tomography in the evaluation of the palmar structures of the podotrochlear apparatus of healthy adult horses and description of the structures observed in images obtained with these techniques. For this, four images of four anatomical parts were performed, and subsequently sectioned and used for the anatomical description. The use of anatomical parts helps in the understanding of normal anatomy leading to a better interpretation of the images and increasing the specificity of the diagnostic for detecting changes that cause diseases. Ultrasonography provides relevant information about these structures to be studied and the association with computed tomography (CT) increased the accuracy of the investigation. Despite the use of CT being more suitable for bone tissue it provides important information and can be used as a useful tool when there is no available MRI.</p><p></p
Systemic toxic reaction due to multiple honeybee stings in equine: Case report
<div><p>ABSTRACT Accidents caused by insects of the Hymenoptera are rarely described in large animals. The attacks caused by honeybee (Apis mellifera) may cause severe consequences and its intensity changes according to the number of stings. Local and systemic reactions can occur, including progression to death. This report describes a case of honeybee attack on an equine, which took place in the city of Lages, in the state of Santa Catarina, Brazil. In the clinical assessment the horse showed apathy, anorexia, head and pectoral edemas, dyspnea, icteric mucosa, increased mandibular lymph nodes and darkened urine. The blood count showed anemia and serum biochemical tests suggested, muscular and hepatic lesions. The urinalysis test indicated hemoglobinuria and increased clotting time. Treatment included lactate Ringer’s solution fluid therapy, furosemide, promethazine, corticosteroids and 20% mannitol solution. Hot and cold compresses were applied alternately on areas with edema. There was a satisfactory response to treatment and the animal was discharged after 30 days in veterinary hospital. The description of honeybee sting accidents in large animals is important because of the evolution that can lead to death. The early approach associated with appropriate treatment, avoiding the worsening of the lesions is fundamental for the recovery of the patient.</p></div
Chronic renal failure in equine due to ascending pyelonephritis predisposed by cauda equina syndrome: case report
<div><p>ABSTRACT This report describes the case of a mare, of the Campeiro breed, used as an embryo donor, which had recurrent cystitis and urinary incontinence crisis. Clinical signs evolved to progressive weight loss, anorexia, apathy, and isolation from the group. Physical examination showed tail hypotonia, perineal hypalgesia, rectal and bladder sagging compatible with signs related to cauda equina syndrome. Complementary laboratory and sonographic assessment, and necropsy confirmed the diagnosis of chronic renal failure (CRF), which was attributed to the ascending pyelonephritis. The examination of urine culture showed growth of bacteria of the genus Streptococcus sp. This is a rare case in the equine species where the lower motor neuron dysfunction led the development of infectious process in the urinary tract, progressing to renal chronic condition incompatible with life.</p></div
