ABSTRACT
Non-strangulated acquired hernias in stallions are rare, especially when the herniated content is not intestinal loops. Thus, the aim of the current study is to describe a case of acquired non-strangulated inguinoscrotal hernia in a stallion, whose herniated content was the omentum. The patient was a Criollo stallion with history of rhabdomyolysis, laminitis and bilateral scrotal volume increase observed in the left scrotal region. The animal presented pain in both thoracic limbs, abnormal blood test, especially hypoproteinemia, and mild pain during palpation in the left inguinal ring region. Hydrocele secondary to hypoproteinemia was suspected. After admission, the animal showed signs of acute abdomen, which were clinically reversed. With this, the animal was subjected to ultrasound examination of the scrotal region, whose findings suggested non-strangulated inguinal hernia, although the content could not be identified. Surgical treatment was chosen in order to identify the herniated content and remove the left testicle. Access to the affected scrotum was performed, in which the presence of fluid and a portion of the omentum was observed surrounding the testis and adhering to it. The animal was discharged after he recovered from the surgery and from laminitis. During the breeding season, the stallion remained with a herd of mares for natural mating. After 15 months of surgery, the animal was reassessed and showed no active signs of inflammatory and degenerative processes in the remaining testis. On this occasion, a pregnancy diagnosis was also performed, and all the mares were pregnant. It is concluded that the presence of omentum as a herniated content does not represent a surgical emergency but can make the reproductive prognosis reserved. In addition, removal of the affected testicle can benefit the spermatogenesis of the remaining testicle.(AU)
As hérnias adquiridas não estranguladas em garanhões são raras, principalmente quando o conteúdo herniado não é de alças intestinais. Assim, o objetivo deste trabalho foi descrever um caso de hérnia inguino escrotal adquirida e não estrangulada em garanhão, cujo conteúdo herniado era composto pelo omento. Foi atendido um garanhão da raça Crioula com histórico de rabdomiólise, laminite e aumento de volume escrotal bilateral, evidenciado na região escrotal esquerda. O animal apresentava dor nos membros torácicos, alterações na avaliação sanguínea, destacando-se a hipoproteinemia, e demonstrava dor leve à palpação na região do anel inguinal esquerdo. Suspeitou-se de hidrocele secundária a hipoproteinemia. Após a internação, o animal apresentou sinais de abdômen agudo, revertidos clinicamente. Com isso, realizou-se ultrassonografia da região escrotal, cujos achados sugeriram hérnia inguinal não estrangulada, sem que o conteúdo pudesse ser identificado. Optou-se pelo tratamento cirúrgico, com o intuito de identificação do conteúdo herniado e remoção do testículo esquerdo. Foi realizado acesso à bolsa escrotal afetada, na qual se observou presença de líquido e de uma porção do omento envolvendo o testículo e aderido a ele. O animal recebeu alta após restabelecimento da cirurgia e da laminite. Na propriedade, durante temporada reprodutiva, o garanhão permaneceu com uma manada de éguas para realização de monta natural. Passados 15 meses da cirurgia, o animal foi reavaliado e não demonstrou sinais ativos de processo inflamatório e degenerativos no testículo remanescente. Nessa ocasião, também foi realizado diagnóstico de gestação e todas as éguas encontravam-se prenhes. Conclui-se que a presença de omento como conteúdo herniado não representa uma emergência cirúrgica, mas pode tornar o prognóstico reprodutivo reservado. Ainda, a remoção do testículo afetado pode trazer benefícios à espermatogênese do remanescente.(AU)

During 1983, a series of trials was carried out in Greece, Italy and Jordan, to test the efficacy of the aminocyclitol antibiotic apramycin as a treatment for naturally acquired Escherichia coli infections in broilers. The trials involved a total of 40,389 broilers, 27-39 days of age, in twelve houses at eight different production sites. Three levels of apramycin medication were evaluated: 125, 250 and 500 mg activity/litre drinking water, administered for five consecutive days. Treatment was only initiated after disease had been confirmed by laboratory examination of dead birds. Not all treatments were evaluated in every house. However, each house contained a group of unmedicated birds as controls, while the remaining birds were allocated to one or more apramycin treatment groups. There was a reduction in mortality and an improvement in the final weight and the economic feed conversion ratio in all three treatment groups. The data presented provide support for the use of apramycin sulphate administered in the drinking water for the treatment of E. coli infections in broilers.

The effect of the concentration of plasma protein on the recovery from anaesthesia induced by equipotent doses (UD95) of thiopentone and Althesin was studied in 48 patients. The recovery time (RT) wa plotted against the concentrations of total plasma proteins (TPP) and albumin (Al). A small decrease in TPP concentration from normal range affected the recovery time minimally; a small decrease in TPP concentration from a low basal value markedly increased the recovery time with both agents. A large decrease in TPP concentration increased the recovery time from thiopentone and Althesin markedly.

The effect of proteinaemia and albuminaemia changes on recovery time following administration of an equipotent dose (DPC95) of thiopentone and alphaxolone has been evaluated. The study was carried out on two groups of 24 patients premedicated with atropine alone. Recovery time was more closely related to variations in albuminaemia compared to variations in total proteins: this results that albumins are the main binding-site of i.v. anaesthetics. Variations in total proteins and albuminaemia affect recovery time to a lesser extent when alphaxolone is used, compared with thiopentone. The result is related to the lower alphaxolone binding fraction. The clinical implications of protein binding fraction of anaesthetics is discussed.

Mathematical calculations were employed in an assessment of the resistances associated with a passive outward conveyance system for the removal of anesthetic gases and fumes from operating theatres. It was found that the magnitude of such resistances was not enough to interfere with the patient's respiratory dynamics.
