Myasthenia gravis canine: A differential diagnosis for infectious diseases of origin neurological

Myasthenia gravis (MG) is a neuromuscular disorder caused by a reduction in the number of functional nicotinic acetylcholine receptors in the postsynaptic membrane. Some infectious neurological diseases can mimic this situation. The study describes a case of MG in dogs, showing the conduct in diagnosis and therapy, in addition to providing the Revista Brasileira de Higiene e Sanidade Animal Brazilian Journal of Hygiene and Animal Sanity ISSN: 1981-2965

ACHADOS CLÍNICO-EPIDEMIOLÓGICOS DE 25 CASOS DE CÓLICA EM EQUÍDEOS NO RIO GRANDE DO NORTE

The present article aimed to conduct a retrospective study of the main clinical and epidemiological findings in 25 cases of colic in equidae from Rio Grande do Norte. Twenty five equidae (21 horses, three mules and one donkey) were included. Clinical treatment was performed in 15 equidae with moderate large colon impaction (n = 6), cecal bloat (n = 4), gastric overload (n = 3), cecal impaction (n = 1) and gastric ulcers (n = 1). Six horses with severe large colon impaction (n = 2), meconium impaction (n = 2), left dorsal displacement of the large colon (n = 1) and verminotic arteritis (n = 1) were submitted to exploratory laparotomy. Four horses were not treated due to severe systemic disturbances and poor prognosis. Higher incidence occurred in Quarter horses and crossbreed horses followed by mules and single cases in a pony and a donkey. Impactions of the large intestine and cecal bloat were the major causes of colic in equidae from this study; and mainly resulted from erroneous feeding management by the owners or handlers.

Tratamento conservativo e cirúrgico em 22 ruminantes com fraturas em membros

The aim of the present study was to report the main locations of limb fractures in 22 ruminants and to determine the efficiency of the treatment choices. Eight goats, eight sheep and six cattle were included. In cases of distal fractures, the conservative treatment with immobilization was the method of choice. In cases of proximal, exposed metatarsal or metacarpal fractures, the ruminants were treated surgically. The higher frequency of fractures involved the metacarpal or metatarsal (54.5%) followed by fractures of the tibia (22.7%), femur (9%) and isolated cases of medial phalanx, humerus, radius and ulna fractures (4.5% each). Total recovery rate reached 95.4%. Immobilization with plaster associated with Thomas splint, or just with wooden splints in young animals, was efficient in reducing fractures of metacarpal, metatarsal, tibia, humerus, and radio in the treated ruminants. In the case of medial phalanx fracture, immobilization using only plaster was sufficient to provide adequate bone repair. The internal or external skeletal fixation should be considered an option in the treatment of metacarpal, metatarsal, tibial and femoral fractures in ruminants, especially in low body weight animals.
