Acromegaly due to a somatroph adenoma in a dog

A 10-year-old uncastrated male Dalmatian dog was referred for gait abnormalities consisting of chronic progressive stiffness and rigidity. Other symptoms were polyphagia associated with weight gain, polyuria and polydipsia, excessive panting, and an inspiratory stridor. The owner had noticed progressive thickening of the skin and enlargement of the tongue over the last 3 years. Physical examination revealed thickening of the skin, redundant skin folds, and enlargement of the tongue. The only remarkable abnormalities found on routine laboratory examination were mild anaemia and an increased serum fructosamine concentration. Circulating concentrations of total thyroxine, free thyroxine, and cTSH, and the results of an ACTH stimulation test were all within reference ranges. The basal serum growth hormone (GH) concentration was markedly elevated (23microg/l) and did not decrease during a glucose tolerance test or after somatostatin administration. The serum insulin-like growth factor-1 concentration was also markedly elevated (1254microg/l). Basal serum insulin concentration was high (95mU/l) and insulin concentrations increased considerably after glucose loading, consistent with insulin resistance. Abdominal ultrasonography showed no abnormalities. Survey radiographs of the vertebral column showed severe spondylosis deformans extending from the cervical to the lumbosacral spine. CT scanning of the skull showed an enlarged pituitary gland with normal enhancement pattern. On post-mortem examination, the entire vertebral column appeared as a single and inflexible structure due to the presence of multiple fused osteophytes. The pituitary gland contained an acidophilic adenoma that immunostained positively for GH (and negatively for ACTH and alpha-MSH). In conclusion, this Dalmatian dog with acromegaly and insulin resistance represents the first case of GH hypersecretion proven to be due to a somatotroph adenoma.     

浓缩饲料配制成全价饲料的方法

浓缩饲料是畜禽生长、健康、繁殖需要的蛋白质、氨基酸、维生素、钙、磷、微量元素以及促进生长和防治疾病的抗生素药物等。它是由蛋白饲料类鱼粉、蚕蛹、血粉、骨粉、饼粕类及矿物常量元素和微量元素、维生素制剂等配合而成。浓缩饲料与农副产品 ,如玉米、大麦、薯类、高梁、米糖、麦麸等合理配制后就是全价饲料。怎样采用浓缩饲料配制成全价饲料 ,提高饲养业经济效益。现将此法介绍如下 ,供广大农户在养殖生产中参考。农户从市上购回猪用浓缩饲料含粗蛋白质４０ % ,要与玉米、大麦、米糠三种饲料配成全价饲料喂２０～６０ｋｇ 阶段的瘦肉…     

Laryngotracheitis outbreak limited to a part of a chicken flock exposed to smoke and chemicals

Laryngotracheitis was diagnosed in a flock of molted, caged table-egg-layers. Morbidity was restricted to an area of the house in which the birds had been exposed to smoke from a fire in the house and to a powdered chemical fire-extinguisher used on the fire. Mortality in this group began to rise 6 days after the fire and continued to be above normal for about 3 weeks. Feed consumption dropped for about 1 1/2 weeks after the fire but was normal or above normal during the rest of the disease outbreak. Egg production dropped slightly for 1 week after the fire, then returned to normal. Microscopic tracheitis in the exposed birds continued for 11 weeks after the fire. Hens outside of the smoke-affected area did not show histopathological changes or shed laryngotracheitis virus.     

Exophthalmus secondary to a sinonasal cyst in a horse

CASE DESCRIPTION: A 13-year-old female Miniature Horse was evaluated for progressive unilateral exophthalmia of the left globe of 3 weeks' duration. CLINICAL FINDINGS: Results of a physical examination were unremarkable. Ophthalmic examination identified exophthalmus of the left globe with complete resistance to retropulsion and mild blepharoconjunctivitis. Computed tomography revealed a large, space-occupying mass within the left caudal maxillary and left conchofrontal sinuses. The mass extended into the left retrobulbar space and contacted the cribriform plate. Trephination yielded copious amounts of turbid yellow fluid. The diagnosis was a sinonasal cyst. TREATMENT AND OUTCOME: Subtotal surgical excision of the cyst via a frontonasal osteoplastic flap was curative, with complete resolution of the exophthalmus. Histologic examination confirmed diagnosis of a sinonasal cyst. There was no evidence of cyst recurrence by 4 months after surgery. CLINICAL RELEVANCE: Sinonasal cyst should be a differential diagnosis for retrobulbar disease in horses. Exophthalmia may be the only clinical finding in horses with a sinonasal cyst.
