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.

In 1980, a 10-year-old boy was admitted to the authors' hospital with consciousness disturbance and vomiting. Computerized tomography (CT) scans revealed a pineal mass lesion and hydrocephalus. The tumor was totally removed and a ventriculoperitoneal (VP) shunt was inserted. Histological investigation of a surgical specimen revealed that it was a teratoma. Five years later, the patient was readmitted to the same institution with polyuria. Magnetic resonance (MR) imaging revealed a mass lesion in the suprasellar region. The patient received systemic chemotherapy, and the tumor disappeared; however, 2 years after the chemotherapy, MR imaging demonstrated a right lateral ventricular mass. The tumor was totally resected, and histopathological investigation revealed a teratocarcinoma. Three years after the chemotherapy, CT scanning revealed suprasellar and right lateral ventricular tumor recurrences, for which the patient received irradiation and chemotherapy. The tumors disappeared and the patient achieved complete remission that lasted longer than 10 years. On January 25, 2000, however, he noticed hip pain. Lumbar MR imaging demonstrated a spinal tumor below L-4 and also an abdominal tumor. The abdominal tumor was totally removed, and the histological findings identified it as a germinoma. The patient received systemic chemotherapy and the tumor disappeared completely. The authors believe that the suprasellar tumor was a metachronous germinoma and that it had metastasized through the intrathecal route and the VP shunt.

Five callitrichids (three common marmosets -Callithrix jacchus -, a black tufted-eared marmoset -C. penicillata-, and a saddle-back tamarin -Saguinus fuscicollis) were diagnosed with islet hyperplasia by histopathology and immunohistochemistry. All were privately-owned, unrelated callitrichids ranging from 2- to 4-year-old. Relevant findings were anorexia (3/5), vomiting (2/5), ptyalism (1/5), polyuria/polydipsia (1/5), respiratory distress (1/5), hyperglycemia (2/3) and glycosuria (1/1); hyperglycemia and glycosuria were associated with pregnancy in a common marmoset and resolved after reducing simple carbohydrates in diet. All five animals died, three of them after few premonitory signs; in two cases, other concurrent diseases unrelated to islet hyperplasia were considered the cause of death. Additional animals from two facilities had high weight (4), physical obesity (3), polyuria/polydipsia/polyphagia/uriposia (1), hyperglycemia (1), and/or glycosuria (2). Pathologic findings in the deceased callitrichids were: islet hyperplasia (5/5); hemosiderosis (5/5); lipomatosis (4/5) of several tissues (atria, 3/5; pancreas, gall bladder, intestine, esophagus, and thyroid, 2/5; liver, 1/5); pancreatic necrosis or steatonecrosis, and/or acute pancreatitis (3/5); and vacuolation of hepatocytes and renal tubular cells most likely consistent with hepatorenal lipidosis (2/5). The islets of Langerhans were more numerous and larger than in a control, and morphologically normal in all cases, except in a common marmoset that had a few cells with a foamy cytoplasm and shrunken hyperchromatic or picknotic nucleus. Insulin (5/5), glucagon (3/5), and somatostatin (3/5) immunohistochemistry revealed that most cells stained positively for insulin diffusely in their cytoplasm (5/5) (staining restricted to the vascular pole of b-cells in the control). These findings suggest that obesity, insulin resistance and/or type II diabetes may be implicated and thus a prospective study on these diseases in callitrichids is necessary to determine their etiopathogenesis.

We describe 8 young dogs with congenital dilatation of the intra- and extrahepatic bile ducts and diffuse cystic kidney disease, compatible with Caroli's disease in humans. The dogs were referred between 1980 and 2000 because of chronic disease at an age of 6 months to 3 years. These dogs included 3 Collies, 2 Frisian Stabyhouns, 2 Jack Russell Terriers, and 1 mixed-breed dog. The most common signs were vomiting (6/6), polyuria and polydipsia (4/6), and anorexia (4/6). Ascites was a common finding (4/6). Clinicopathologic abnormalities were available for 6 dogs. All had increased plasma alkaline phosphatase activity and fasting bile acids: increased alanine aminotransferase activity and urea and creatinine concentrations were present in 50% of dogs. Ultrasound examination of the liver showed severely dilated bile ducts without evidence of obstruction, and calcification in all cases but 1. Postmortem examination revealed severe dilatation of the larger intra- and extrahepatic bile ducts. The common bile duct and gall bladder were normal, and the bile system was patent. The ducts contained a clear viscid fluid often with calcified material. Microscopically, marked portal fibrosis was present, often with abnormally structured dilated bile ducts lined with columnar or cuboid epithelium and regularly small calcifications. The lesion was complicated by ascending cholangitis in 1 dog. The kidneys showed marked cortical and medullary fibrosis with a diffuse radial cystic pattern; only slight renal fibrosis was found in the oldest dog. Seven dogs were euthanized without treatment; the oldest dog was alive and well 5 months after diagnosis and was maintained on a protein-restricted diet.

Hypercalcemia is a common, life-threatening metabolic disorder that can be associated with cancer. Its pathophysiology includes enhanced osteoclastic bone resorption and decreased renal excretion of extracellular calcium. Symptoms of hypercalcemia include nausea, vomiting, bone pain, polyuria, renal insufficiency, bradycardia, and arrhythmia. The goals of medical therapy are to inhibit bone resorption and promote renal calcium excretion. Hydration is the first step in management. Treatments for hypercalcemia include phosphates, calcitonin, bisphosphonates, and gallium nitrate. Although intravenous phosphates prevent intestinal calcium absorption and inhibit mineral and bone matrix resorption, serious adverse events include renal failure, hypotension, extraskeletal calcification, and severe hypocalcemia. Calcitonin has a rapid onset of action and can lower serum calcium concentrations within hours, but its usefulness is limited by its short duration of effect and the development of tachyphylaxis. Bisphosphonates are effective inhibitors of bone resorption but appear to have decreased response rates in hypercalcemic patients with high levels of parathyroid-related protein. Gallium nitrate, an antitumor agent noncytotoxic to osteoclasts and bone cells, appears to be more effective than pamidronate, etidronate, and calcitonin in the treatment of cancer-related hypercalcemia. Importantly, unlike bisphosphonates, gallium nitrate is effective in both parathyroid-related protein-mediated and non-parathyroid-related protein-mediated hypercalcemia.

A 2-year-old, castrated male, mixed-breed dog presented with a 1-month history of red eyes and intermittent vomiting and a 2-week history of polyuria and polydipsia. Bilateral anterior uveitis and active chorioretinitis in the left eye were found on ophthalmic examination. Complete blood counts demonstrated evidence of an increased red blood cell mass. Thoracic and abdominal radiographs, abdominal ultrasonography, and Doppler echocardiography were unremarkable. Serum erythropoietin level was low-normal, consistent with a diagnosis of polycythemia vera. Resolution of all systemic and ocular signs occurred, and remission was achieved following phlebotomy and treatment with oral hydroxyurea.

We studied the clinical presentation by age of 36 children with craniopharyngioma, and outcome by height and body mass index (BMI). Presenting symptoms included headache (51.4%), vomiting (31%), visual disturbances (22.9%), polyuria and/or polydipsia (17.1%), delayed puberty (19.4%), short stature (13.8%), and precocious puberty (2.7%). Growth deceleration was overlooked, as was diabetes insipidus (actual rate, 52% for both). Delayed puberty was observed in all patients of appropriate age. Mean height standard deviation score (SDS) at admission was significantly lower than mean target height SDS (p = 0.004), while mean final height SDS was similar (p = 0.14). BMI SDS at last follow-up was similar to mean parental BMI SDS. We conclude that although endocrinopathies are present in most patients with craniopharyngioma, they are rarely the reason for referral. While affected prepubertal children have non-endocrine complaints, most adolescents are referred because of delayed puberty. Diabetes insipidus may be more prevalent in craniopharyngioma than previously reported. When patients with hypothalamic obesity are excluded, mean BMI SDS remains within normal range and is influenced mostly by parental BMI SDS.

A 52-year-old man presented with vomiting, general fatigue and hyponatremia. His symptoms and signs were consistent with the syndrome of inappropriate secretion of antidiuretic hormone (SIADH). Endocrine studies revealed hypopituitarism and administration of hydrocortisone resulted in a marked polyuria. The patient was diagnosed as masked diabetes insipidus. The lymphocytic hypophysitis was also diagnosed on the basis of MRI findings and anti-pituitary antibody. Six months later, these abnormalities disappeared. Diabetes insipidus may exist in a case of hyponatremia due to contrastive SIADH. Such patients may recover spontaneously and careful follow-up is required, avoiding a long-term treatment by monotonous continuation of hormonal replacement.

Hyperparathyroidism is a disease characterized by hypercalcemia with hypophosphoremia resulting from increased secretion of parathyroid hormone (PTH). The disease may be divided into 3 forms: a) primary, b) secondary, c) tertiary (secondary refractory form). Primary hyperparathyroidism is rare in children; hyperplasia is more frequent during the early years of life (neonates and infants) and is difficult to distinguish from adenoma in children. The disease may be asymptomatic; elevated calcemia levels (>12 <13.5 mg/dl) are accompanied by anorexia, asthenia and persistent stipsis; severely elevated concentrations (>13.5 mg/dl) are accompanied by nausea, vomiting, polyuria due to osmosis, with dehydration and progressive onset of lethargy, stupor and coma. Osteopenia or osteitis fibrosa cystica may be present due to augmented bone resorption. Height and weight increases are altered due to anorexia and dehydration. Differential diagnosis includes iatrogenic causes of hypercalcemia (excessive vitamin D intake, prolonged immobilization, etc.) and idiopathic familial hypercalcemia. Emergency treatment is required in cases of extremely elevated hypercalcemia (Ca >13.5-14 mg/dl), due to risk of injury to the heart, the central nervous system, the gastrointestinal tract and the kidneys. The 4 cardinal points of treatment are: hydration, calciuresis, inhibition of bone calcium resorption, treatment of the cause underlying hyperparathyroidism. Secondary hyperparathyroidism is found in cases where chronic hypocalcemia is present, particularly in chronic renal failure, untreated deficiency rickets, chronic intestinal malabsorption, hepatobiliary disease, types I and II vitamin D-dependent rickets, tubular acidosis or Fanconi's syndrome. The tertiary form is distinguished by the autonomous nature of the parathyroid glands which have become hypertrophic/hyperplastic due to uncontrollable, chronic severe renal failure. It can also be of iatrogenic origin due to excessive intake of inorganic phosphates in familial hypophosphatemic rickets or chronic vitamin D deficiency.

Lymphosarcoma, a common canine hematopoietic neoplasm, occurs in multicentric, alimentary, mediastinal, and extranodal forms. Alimentary lymphoma accounts for approximately 5% of cases and is less easily diagnosed than the more common multicentric form. Chemotherapy is often effective, but recent therapeutic advances hold great promise for success in treating canine lymphoma. A 4-year-old, black Labrador retriever was presented (day 1) with a 2-day history of vomiting, polyuria/polydipsia, lethargy, and anorexia. The heart and respiratory rates were within normal limits, and the rectal temperature was 38.9 degrees C. Abdominal splinting was noted on palpation, which elicited urination. No obvious additional abnormalities were detected.
