A 7-year-old adult male ferret had progressive hair loss that was bilaterally symmetric. Also clinically evident were severe dehydration, polydipsia, muffled heart sounds, weak femoral pulses, hepatomegaly, lethargy, weakness, temporal muscular atrophy, dyspnea, and weakness. The blood profile of the ferret indicated profound leukopenia, eosinopenia, and high phosphorus, BUN, creatinine, and potassium concentrations, as well as high aspartate transaminase activity; the albumin concentration was low. The serum cortisol concentration was 8.1 micrograms/dl. Necropsy and histologic findings confirmed a diagnosis of hyperadrenocorticism, complicated by dilatative cardiomyopathy, chronic active hepatitis, and renal disease.

Of cases of hyperadrenocorticism in small animals 80-85% are the result of adrenocortical hyperplasia. Middle-aged or older Poodles, Dachshunds, Boston Terriers and Boxers are most commonly affected, and cats rarely. Clinical signs include polydipsia, polyuria, alopecia, abdominal distension, lethargy, weakness, hepatomegaly, calcinosis cutis, testicular atrophy and anestrus. Hematologic and biochemical changes may include neutrophilia, lymphopenia, monocytosis, eosinopenia, increased blood levels of alkaline phosphatase, SGPT, cholesterol, Na and glucose, and decreased K and T4 levels. The high-dosage dexamethasone suppression test helps differentiate pituitary-dependent hyperadrenocorticism from that caused by adrenal tumors. The low-dosage dexamethasone suppression test, determination of plasma ACTH levels, and ACTH response test are additional diagnostic aids in the diagnosis of Cushing's disease. Medical treatment involves oral use of mitotane (o,p'-DDD) at 50 mg/kg/day for 7 days and prednisone or prednisolone at 0.05 mg/kg/day. Hypophysectomy has been used with only 5% mortality in cases of pituitary-dependent hyperadrenocorticism. Adrenalectomy is indicated in cases of adrenal neoplasia.

Although the definitive diagnosis of enteric fever requires the isolation of Salmonella enterica serotype typhi or paratyphi, the diagnosis is usually made according to clinical and laboratory findings. There is usually a diagnostic dilemma. The aim of this study was to determine the minimum required parameters that could be valuable in the diagnosis of enteric fever. A retrospective study was performed to compare the clinical and laboratory findings in 60 patients who proved to have enteric fever by cultures and 58 patients with non-enteric fever. Features independently predictive of enteric fever were assessed by multivariate logistic regression. Sensitivity, specificity and positive predictive and negative predictive values were estimated. Significant clinical features of enteric fever were hepatomegaly, splenomegaly, relative bradycardia, rose spots, leucopenia, trombocytopenia, eosinopenia and elevated AST level. Five of these features were found to be predictive for the diagnosis of enteric fever; splenomegaly, relative bradycardia, rose spots and trombocytopenia and elevated AST level. In conclusion, clinical and laboratory findings can help the clinician to diagnose enteric fever in the absence of microbiological confirmation.
