Acute renal failure (ARF) is characterised by progressive azotaemia, and for therapeutic purposes consideration of prerenal, intrinsic renal and postrenal types still holds good. Prerenal azotaemia is generally caused by loss of body fluids or blood, whereas postrenal azotaemia is effected by acute or chronic urinary tract obstruction. Provided these conditions are recognised on time and treated, they are reversible. However, delay in recognition or treatment could result in renal parenchymal damage and sustained ARF. Therefore utmost attention should be focused on identifying reversible factor(s) in the setting of ARF. Once reversible factors have been excluded, and ARF becomes sustained, a diagnosis of acute intrinsic renal failure is almost certain. Lack of natriuretic and diuretic responses to fluid challenge or infusion of furosemide (frusemide) and dopamine are further indications of this possibility. Management of acute intrinsic renal failure essentially consists of dietary control and dialysis therapy. The latter facilitates fluid and electrolyte management, but does not reduce the overall mortality. The potential benefit of parenteral hyperalimentation to promote renal function recovery must be carefully weighed against the risk of severe infectious complications.

The medical records of 14 hyperthyroid cats with thyroid carcinoma were analyzed retrospectively regarding historical, physical, laboratory, and thyroid scintiscan findings, treatment, and treatment outcome. Breed predilection was not detected, and older castrated male cats were most commonly affected. The most common clinical signs detected by owners were weight loss, polydipsia, polyuria, polyphagia, hyperactivity, and anorexia. Physical examination findings included tachycardia, palpable cervical mass, hyperactivity, cardiac murmur, and abnormal coat. Common abnormal laboratory findings were high serum thyroxine and triiodo-thyronine concentrations and high serum alanine transaminase, alkaline phosphatase, and aspartate transaminase activities. Azotemia, hyperphosphatemia, and hyperglycemia were noticed less frequently. The most common thyroid scintiscan findings were multiple nodular areas of high radionuclide uptake in the cervical region, thoracic inlet, and cranial mediastinum. The most common morphologic diagnosis was mixed compact and follicular carcinoma, with follicular and papillary carcinomas being less common. Most cats responded well to treatment of the thyroid tumor, with rapid resolution of the historical and physical examination findings. The most common necropsy findings were local tumor invasion, regional lymph node metastases, cardiomyopathy, and interstitial nephritis.
