Change in serum thyroid-stimulating hormone concentration in response to administration of thyrotropin-releasing hormone to healthy dogs, hypothyroid dogs, and euthyroid dogs with concurrent disease.
To determine whether measuring change in serum thyroid-stimulating hormone (TSH) concentration in response to thyrotropin-releasing hormone (TRH) administration can be used as a test of thyroid function in dogs suspected of having hypothyroidism. ⋯ Although percentage change in TSH concentration in response to TRH administration can be used to differentiate euthyroid from hypothyroid dogs, the test has little advantage over measurement of baseline TSH and total or free T4 concentration.

Case ReportsLaparoscopic diagnosis of subcapsular splenic hematoma in a horse.
A 5-year-old Quarter Horse was examined after it developed signs of abdominal discomfort as a result of a training accident. Oral mucous membranes were pale, and capillary refill time was > 3 seconds. Hematologically, the PCV was low, and abdominocentesis yielded a serosanguineous fluid. ⋯ Laparoscopic examination revealed a 7.5-cm-diameter splenic hematoma contained within the splenic capsule, confirming the diagnosis of subcapsular splenic hematoma. Abdominal laparoscopy provided excellent observation of the spleen and allowed for thorough evaluation and determination of the extent of the lesion. This information aided the clinician in reaching a definitive diagnosis and choosing between splenectomy and medical treatment.
