The physical findings, clinical signs, age, breed and sex distributions, and laboratory data of 117 dogs with untreated Cushing's syndrome were reviewed. Poodles, Dachshunds, and Boxers of all ages were found to be at increased risk, as were dogs of all breeds greater than or equal to 6 years old. Polydipsia, polyuria, progressive bilaterally symmetric alopecia, and abdominal distention were the most frequently observed clinical signs and physical findings. Lymphopenia, eosinopenia, above normal values of serum alkaline phosphatase, serum cholesterol, and sulfobromphthalein dye retention, and below normal urine specific gravity were the most frequent abnormalities found in the laboratory data. About 50% of the dogs had urinary tract infections. Final diagnosis was established on the basis of abnormally high plasma corticosteroid values in response to an intramuscular injection of adrenocorticotropic hormone.

Primary hypoadrenocorticism was diagnosed in ten young to middle-aged cats of mixed breeding. Five of the cats were male, and five were female. Historic signs included lethargy (n = 10), anorexia (n = 10), weight loss (n = 9), vomiting (n = 4), and polyuria (n = 3). Dehydration (n = 9), hypothermia (n = 8), prolonged capillary refill time (n = 5), weak pulse (n = 5), collapse (n = 3), and sinus bradycardia (n = 2) were found on physical examination. Results of initial laboratory tests revealed anemia (n = 3), absolute lymphocytosis (n = 2), absolute eosinophilia (n = 1), and azotemia and hyperphosphatemia (n = 10). Serum electrolyte changes included hyponatremia (n = 10), hyperkalemia (n = 9), hypochloremia (n = 9), and hypercalcemia (n = 1). The diagnosis of primary adrenocortical insufficiency was established on the basis of results of adrenocorticotropic hormone (ACTH) stimulation tests (n = 10) and endogenous plasma ACTH determinations (n = 7). Initial therapy for hypoadrenocorticism included intravenous administration of 0.9% saline and dexamethasone and intramuscular administration of desoxycorticosterone acetate in oil. Three cats were euthanatized shortly after diagnosis because of poor clinical response. Results of necropsy examination were unremarkable except for complete destruction of both adrenal cortices. Seven cats were treated chronically with oral prednisone or intramuscular methylprednisolone acetate for glucocorticoid supplementation and with oral fludrocortisone acetate or intramuscular injections of repository desoxycorticosterone pivalate for mineralocorticoid replacement. One cat died after 47 days of therapy from unknown causes; the other six cats are still alive and well after 3 to 70 months of treatment.

Clinical manifestations and endocrine functions were evaluated in 17 children with suprasellar germinoma. Polyuria and growth retardation were the most common initial symptoms. Physical and neurological examinations revealed diabetes insipidus in 17, growth retardation in five, and visual disturbance in three of the patients. Assessment of hypothalamic-pituitary function before treatment revealed pituitary deficits in all patients involving growth hormone, thyroid-stimulating hormone, luteinizing hormone, follicle-stimulating hormone, and adrenocorticotropic hormone. These pituitary dysfunctions persisted after tumor remission due to radiation therapy. These results indicate that children with suprasellar germinoma need long-term hormone replacement therapy to prevent growth retardation, thyroid dysfunction, and delayed secondary sexual development.

A 9-year-old male Doberman Pinscher was referred to the Department of Clinical Sciences of Companion Animals, Faculty of Veterinary Medicine, Utrecht University, for polyuria/polydipsia, anorexia, and vomiting. Laboratory examination of blood and urine revealed hyperglycemia, glucosuria, and acidosis. Diabetes mellitus was diagnosed but was very resistant to subsequent insulin treatment. At the owners' request, the dog was euthanatized and a postmortem examination was performed. In addition to hepatic, pancreatic, and renal changes compatible with diabetes mellitus, an acidophilic adenoma of the adenohypophysis was found. Immunohistochemical staining for growth hormone, adrenocorticotropic hormone, and prolactin showed a strong immunolabeling for growth hormone within the cytoplasm of the tumor cells. Although growth hormone level was not measured in the plasma, our findings suggest that the diabetes mellitus in this dog was caused by excess growth hormone secreted by the pituitary neoplasm.

A 44-year-old woman with Marie-Bamberger's syndrome and diabetes insipidus had a lung tumour with mediastinal metastases, but no signs of metastases to the hypothalamus or pituitary gland. A week after removal of the tumour, the joint pain, polyuria and polydipsia disappeared. The tumour was diagnosed histopathologically as a moderately differentiated adenocarcinoma with focal neuroendocrine cell differentiation and dispersed cells reacting with antisera against neurone-specific enolase, S-100 protein, neuropeptide Y, follicle-stimulating hormone, substance P, vasoactive polypeptide (VIP), adrenocorticotropic hormone and pancreatic polypeptide (PP) as well as to one of three tested antisera raised against antidiuretic hormone (ADH). It was suggested that Marie-Bamberger's syndrome might be caused by one of these immunoreactive substances or by a substance that shares an amino acid sequence with one of these neuroendocrine peptides. It was also suggested that the tumour might produce an ADH-like substance which might have an ADH-antagonist effect.

Primary hypoadrenocorticism was diagnosed in an eight-year-old neutered male cat. The predominant presenting complaint was dysphagia. Other historical signs included lethargy, weight loss, polydipsia, polyuria, muscle weakness and occasional vomiting. The signs had waxed and waned over the two months before presentation and had improved when the cat was treated with enrofloxacin and prednisolone by the referring veterinarian. On referral, dehydration, depression and poor bodily condition were found on physical examination. Results of initial laboratory tests revealed mild anaemia, hyperkalaemia, hyponatraemia, hypochloraemia and elevations in serum creatinine and creatine kinase. The diagnosis of primary adrenocortical insufficiency was established on the basis of results of an adrenocorticotropic hormone (ACTH) stimulation test and endogenous plasma ACTH determination. Initial therapy for hypoadrenocorticism included intravenous administration of 0.9 per cent saline and dexamethasone, and oral fludrocortisone acetate. Within one week the cat was clinically normal and two years later was still alive and well on fludrocortisone acetate treatment only.

A 9-year-old, spayed female domestic shorthair cat presented for polyphagia, polydipsia, and polyuria following chronic methylprednisolone acetate therapy for pruritus. Initial diagnostics were consistent with uncomplicated diabetes mellitus. Serum calcium was within reference range. Within 12 hours the cat developed depression, anorexia, vomiting, and severe dehydration. Laboratory analysis indicated marked hypercalcemia as measured by both ionized and total calcium concentration. No underlying neoplastic or inflammatory process was identified. An adrenocorticotropic hormone stimulation test was indicative of adrenocortical insufficiency. The hypercalcemia resolved with glucocorticoid supplementation and correction of the dehydration. The diabetes mellitus and adrenal insufficiency both resolved within 9 weeks.

A five-year-old, entire, male dachshund was presented with a five day history of hypersalivation and regurgitation as well as polyuria and polydipsia for several months. Chest radiographs demonstrated megaoesophagus and aspiration pneumonia. Furthermore, hyperadrenocorticism was demonstrated by means of elevations in levels of serum alkaline phosphatase and cholesterol, decreased urinary specific gravity, increased response to adrenocorticotropic hormone stimulation, insufficient suppression of the post-dexamethasone plasma cortisol levels, an increased endogenous adrenocorticotropic hormone concentration and bilaterally enlarged adrenal glands on abdominal ultrasound. The dog became severely dyspnoeic and was euthanased after magnetic resonance imaging was performed. The magnetic resonance imaging and necropsy revealed the sellar region mainly filled with fluid, with only small tissue remnants, a condition defined as empty sella syndrome in human medicine. To the author's knowledge, this is the first dog described with empty sella syndrome and only the second dog described with hyperadrenocorticism secondary to ectopic adrenocorticotropic hormone production. However, the association between empty sella syndrome and hyperadrenocorticism may be no more than incidental.

A 54-year-old woman had been given a diagnosis with scleroderma and interstitial pneumonia due to scleroderma when she was 45 years old. Thirst, with resulting polydipsia and polyuria (about 7 liters/day) were present since May, 2004, and bloody sputum appeared in June of 2004. The patient was admitted to our hospital. Chest CT examination showed multiple nodules in the bilateral lower lung field and multiple movable subcutaneous nodules on the abdomen. Small-cell lung cancer (metastases in the pituitary, subcutaneous tissue, and lungs) was diagnosed by transbronchial lung biopsy and subcutaneous nodule biopsy of the abdomen. The final diagnosis was diabetes insipidus and Cushing syndrome. Chemotherapy was done with CDDP and VP-16, which resulted in reduction of the tumor and improvement in endocrinological findings. Nevertheless, chemotherapy could not be continued because of infected bullae. The patient died of deteriorating illness after 91 sickness days. We concluded that this case was Cushing syndrome caused by ectopic adrenocorticotropic hormone-producing small cell lung cancer, and that it presented with diabetes insipidus because of pituitary metastasis. Therefore, when drastic endocrinological changes are found, it is important to examine for cancer, including lung cancer, as soon as possible.

A 12-year-old, intact female beagle exhibited symptoms of polyuria-polydipsia and hyperorexia for two months. Blood tests showed elevated asparate aminotransferase, alanine aminotransferase, alkaline phosphatase and creatine kinase levels, as well as marked hypokalemia. The results of adrenocorticotropic hormone stimulation test showed elevated cortisol, aldosterone and corticosterone concentrations. Abdominal ultrasonography confirmed a mass in the left adrenal gland. Masses were also seen in the liver and caudal vena cava. Diagnosis was a tumor of the adrenal cortex with metastases. Trilostane administration was initiated. The dog initially showed improved demeanor as a result of regulating hormone secretion. However, after 88 days, the dog weakened rapidly, before dying on the 117th day. Pathological findings confirmed a diagnosis of adrenocortical carcinoma.
