Horner-s Syndrome following common carotid artery translocation in a horse: case report / Síndrome de Horner após transposição de carótida em equino: relato de caso

Horner's syndrome (HS) is a sympathetic dysfunction caused by injuries to the sympathetic pathway. A clinical case of HS following common carotid artery transposition and catheterization in a horse is described. The animal presented head and neck sweating with focal skin temperature elevation, facial paralysis and ptosis. Most clinical signs were transient and persisted for two hours following percutaneous catheter removal. Recurrence of clinical signs was observed at subsequent catheterizations. Ptosis endured for 10 months as a consequence of the first catheter placement which demonstrates the importance of careful manipulation of the anatomical structures of the neck when performing any surgical manipulation in this area...

A síndrome de Horner é uma disfunção do sistema nervoso autônomo simpático, decorrente de qualquer injúria a essa via de transmissão nervosa. Este artigo descreve um caso da síndrome após cirurgia para a transposição da artéria carótida comum. Os sinais clínicos observados foram sudorese de face e pescoço, com hipertermia localizada, paralisia facial e ptose palpebral. A maioria dos sinais foi transitória e se manifestou por até duas horas após a remoção do cateter percutâneo, introduzido na artéria transposta. Como essa manifestação foi recorrente nas venóclises subsequentes e a ptose palpebral perdurou por 10 meses, desde a primeira punção arterial, ressalta-se a importância e o critério quando da necessidade de manipulação cirúrgica dessa região anatômica...

Laparoscopic ovum collection in sheep: gross and microscopic evaluation of the ovary and influence on ooctye production.

Gross and microscopic evaluations of the ovaries of sheep subjected to successive ovum collection were performed with the objective of identifying if there was interference in oocyte production and morphology of gonads. Gross evaluation of the internal genital tract was also performed. Eighteen ewes of the Santa Inês breed were randomly distributed into three experimental groups of six animals each; G0, G1 and G9 with no, one and nine repetitions, respectively. Estrous synchronization was achieved with a short protocol using MAP followed by single dose stimulation with 80mg of FSHp and 300 IU of eCG (IM). Laparoscopic ovum pick-up was performed 36h later, with 7-day intervals. The number of visualized follicles, aspirated follicles and oocytes recovery was recorded. After the last intervention, ovariectomy was performed for evaluation of gross and microscopical appearance and existence of lesions caused by follicular puncture, which were classified as absent (0), mild (1), moderate (2) and severe (3). The number of visualized follicles, aspirated follicles and oocytes recovery were 13.2±2.0, 11.3±3.0 and 5.8±2.3, respectively, with a recovery rate of 51.7%. No statistical difference was found between the nine sessions (P>0.05). Nine sessions of superovulation and ovum collection procedures did not cause ovarian lesions and did not interfere with the production of follicles in ewes of the Santa Inês breed.
