Bilateral Polydactyly in a foal

The following case report describes the diagnosis and surgery of bilateral polydactyly of unknown origin in a colt. A 7-month-old Berber colt was referred for cosmetic and curative excision of supernumerary digits. Radiographic examination revealed bilateral polydactyly and well-developed first carpal bones. Surgery consisted of an osteotomy of both second metacarpal bones combined with an amputation of the supernumerary digits. The follow-up at 18 months after surgery revealed a sound horse with an excellent cosmetic outcome

Autologous conditioned plasma as therapy of tendon and ligament lesions in seven horses

This case report describes the intralesional application of autologous conditioned plasma (ACP) in seven horses as treatment of severe tendinitis of the superficial digital flexor tendon, deep digital flexor tendon, or desmitis of the inferior check ligament. Follow-up data of the horses revealed a positive outcome in 10 to 13 months post injury. All horses treated with ACP were either performing in their previous work-load or were back in full training. Further studies with long-term follow-up will have to be performed to support these clinical intermediate-term observations

Isolement du pepsinogène équin

Le pepsinogène est une protéine sécrétée par l'estomac qui, en milieu acide, donne la pepsine dont le rôle est la dégradation des protéines au cours du processus de digestion gastrique. La muqueuse glandulaire de l'estomac de deux chevaux sains est soumise à une extraction et une précipitation en milieu neutre puis à une chromatographie sur trois colonnes différentes afin d'isoler le pepsinogène équin. L'analyse électrophorétique fait apparaître plusieurs protéases dont la confirmation de la nature définitive nécessiterait un séquençage des acides aminés. D'après les données précédemment acquises dans les autres espèces, le pepsinogène équin obtenu dans notre étude présente un poids moléculaire de 45 kDa. Ce pepsinogène isolé pourra servir de base à l'élaboration d'une technique de dosage spécifique du pepsinogène équin dans le sang. L'étude de la corrélation entre le taux de pepsinogène sanguin et les différentes affections gastriques permettrait d'utiliser cette mesure dans un but diagnostic de ces affections.MAISONS-ALFORT-Ecole Vétérin (940462302) / SudocSudocFranceF

Use of a deslorelin implant for influencing sex hormones and male behaviour in a stallion — Case report

This case report describes the use of a subcutaneously applied 4.7-mg deslorelin acetate implant in a three-year-old Arabian crossbred stallion showing unwanted strong male behaviour. Following deslorelin acetate implantation the stallion showed a short transitional increase in male behaviour. A ‘gelding-like’ behaviour was noted 15 days (D15) after treatment. The horse was surgically castrated at the owners request at D52 after treatment. Serum testosterone, oestradiol-17β and oestrone sulphate values decreased after deslorelin acetate implantation, but serum LH and FSH levels remained unchanged. Histopathological analysis of both testes and sperm analysis revealed a reduced spermatogenesis at D52. The testicular volume decreased after treatment. The use of a subcutaneously applied deslorelin acetate implant might be a promising tool to change the behaviour of aggressive stallions
