The effect of a high-cholesterol (CHOL) diet and corticosteroids on the toxicity of vitamin D2 (VD2) in rats was studied. VD2 was administered orally at the dosage of 5-60 x 10(4) IU/kg, once daily for 4 days. Animals fed CHOL showed a decrease in mortality due to VD2 treatment. Dietary CHOL inhibited toxic responses such as a diminished growth rate following anorexia, elevated serum calcium level and calcium deposition in tissues, which were produced by a sublethal dose of VD2 (20 x 10(4) IU/kg, once daily for 4 days). Animals pretreated with the high-CHOL diet from 2 weeks before the first VD2 administration showed much more symptomatic relief than those given this diet after the first VD2 administration. On the other hand, dexamethasone (DEX) as well as corticosterone remarkably increased the mortality due to VD2. The degree of VD2 toxicity, enhanced by DEX, was correlated with the degree of hypercalcemia and tissue calcification. Therefore, the inhibitory effect of CHOL is not likely to be due to activation of the CHOL-corticosterone system in the adrenal gland.

Hypercalcemia (12.0 to 18.3 mg/dl) was detected in 3 cats that had eaten a rodenticide that contained cholecalciferol. Clinical signs included lethargy, anorexia, vomiting, and polydipsia. Treatment with furosemide and fluids administered IV resulted in normalization of the serum calcium concentration and in remission of the clinical signs in 2 cats. One cat with a serum calcium concentration of 18.3 mg/dl did not have clinical signs, was not treated, and was reportedly normal 9 months after initial examination. We attributed the uniformly favorable outcome of exposure to the rodenticide in these cats to the small quantity of the toxin ingested.

Thirteen patients with hematological neoplasms were treated with Bestrabucil (100 mg/day po, total dose 700-9,900 mg), which is the benzoate of an estradiol-chlorambucil conjugate. The diseases from which they suffered consisted of T-cell leukemia (3), lymphoma (3), myeloma (5) and essential thrombocytosis (2). Although this drug was less effective against myeloma, the other diseases were more or less relieved with this medication. That is, Bestrabucil was effective in all three patients with T-cell leukemia, both with essential thrombocytosis and two of the three with lymphoma. It is most interesting that adult T-cell leukemia (ATL) cells decreased remarkably with Bestrabucil, along with the disappearance of several symptoms (bone pain, hypercalcemia etc.). The main side effects during this medication were mammary pain (eight of 13 patients, 62%), anorexia (five of 13 patients, 39%) and loss of libido (three of 13 patients, 23%), but neither severe myelosuppression nor hepatorenal dysfunction was induced.

A 58-year-old man, born in Nagasaki prefecture, was admitted to our hospital because of anorexia and general fatigue on November 22, 1984. Hepatosplenomegaly was found without skin eruption. The blood examination on admission revealed leukocytosis (50,800/microliter) and atypical lymphocytes with hyperlobulated nuclei. He had hypercalcemia, and hepatic and renal damage. A diagnosis of adult T cell leukemia (ATL) in the acute stage was made. Treatment with KM2210, a conjugate of chlorambucil and estradiol, was started, and his peripheral leukocytes decreased gradually reaching, 19,700/microliter by the end of this medication. His leukocyte count continued to decrease after discontinuation of KM2210 and reached a nadir of 4,700/microliter. Hepatosplenomegaly and hypercalcemia also improved. About one month later, recurrence of the disease occurred and he was again treated with KM2210. Although the second course of the KM2210 therapy was also successful in relieving hepatosplenomegaly and leukocytosis, it proved impossible to ameliorate his poor condition and he died of DIC. Our case suggests that KM2210 has a remarkable cytotoxic effect against ATL cells even in the acute stage but the optimal schedule of treatment with this new drug should be established in order to obtain more satisfactory therapeutic results.

Three cases of bladder carcinomas associated with hypercalcemia were presented. Case 1: A 43-year-old male was diagnosed as having bladder carcinoma 2 years ago and treated in another hospital by partial cystectomy with uretero-vesiconeostomy of the left side. On March 6, 1985, in our clinic, he received a total cystectomy with an ileal conduit for urinary bladder carcinoma. A 5-month post-operative clinical examination showed recurrence of the carcinoma with elevated serum Ca level (15.6 mg/dl). He was treated with eel-calcitonin, predonine, indomethacin, and furosemide, but died on August 23, 1985. Autopsy disclosed carcinoma of the urinary bladder (transitional cell cancer much greater than squamous cell cancer). Case 2: A 51-year-old male was diagnosed as having transitional carcinoma of the urinary bladder and was treated in our clinic by total cystectomy with cutaneous ureterostomy. Three months after the operation, he was readmitted with complaints of anorexia and disturbances of consciousness. His serum Ca level was elevated (17 mg/dl), and clinical examination showed recurrence of the carcinoma; bone scan revealed no metastasis. He was treated by radiotherapy with eel-calcitonin, predonine, indomethacin, and furosemide, but died on October 22, 1985. Autopsy disclosed carcinoma of the urinary bladder (squamous cell cancer). Case 3: A 72-year-old male was diagnosed as having a large urinary bladder tumor. An IVP showed a left non-functioning kidney. On admission, he complained of anorexia and confusion. His serum Ca level was elevated (13.8 mg/dl); bone scan revealed no metastasis.(ABSTRACT TRUNCATED AT 250 WORDS)

Two dogs were examined because of anorexia, lethargy, muscle tremors, weakness, and seizures that were associated with an acute onset of hypocalcemia. Both dogs had histories of chronic hypercalcemia. Examination of the parathyroid glands revealed infarction of focal parathyroid adenomas, with atrophy of the remaining parathyroid glands. It was concluded that the acute onset of hypocalcemia was caused by infarction of functional parathyroid adenomas that were previously responsible for the cause of persistent hypercalcemia. Infarction of a parathyroid adenoma should be included in a list of differential diagnoses of acute hypocalcemia in the dog, especially if hypercalcemia has been diagnosed previously.

Endocrine disorders affecting the elderly present a continuing challenge to the clinician. Often confused with normal age-related changes or age-prevalent disease, disorders such as thyrotoxicosis, hyperglycemia, and hypercalcemia often go undetected until late in their course, if at all. Non-specific and atypical presentations make the diagnosis even more difficult and a low threshold for obtaining laboratory testing is advised. Thyrotoxicosis may present with only anorexia, weight loss, and cardiac dysfunction. Hyperglycemia often remains undetected; long-term sequelae, however, may impair function and result in problems such as neuropathy, postural instability, and nephropathy--conditions often dismissed as consequences of old age. Hypercalcemia may not present with the classic findings of renal colic, GI pathology, and skeletal disease. An acute confusional state with or without volume depletion appears to be a more frequent presentation during later life.

Tumours may give rise to systemic complications, among others by the release of specific substances. The accompanying symptoms are referred to as paraneoplastic syndromes. These complications have a marked effect on the course run by the disease. A number of common syndromes which are easy to diagnose, are discussed in a survey of the literature, namely: cachexia, anorexia, fever, hypercalcaemia, hypoglycaemia, anaemia and coagulation defects. Attention is paid to the occurrence of the syndromes in man and dogs, the relationship with specific forms of tumour, the pathogenesis and some forms of possible therapy.

Primary hyperparathyroidism was studied in a well-defined geriatric population of 1129 individuals during a three-month interval. Primary hyperparathyroidism was diagnosed in 1.5%. The diagnosis was based on a morphologic and biochemic basis. From clinical material consisting of 400 patients treated surgically for primary hyperparathyroidism during a ten-year period, 158 patients (38%) above the age of 64 were studied. At the preoperative evaluation, neuromuscular symptoms were present in 80%, renal insufficiency and kidney stones in each 16%, constipation and/or anorexia in 38%. Ten per cent were considered asymptomatic. In 80% the primary hyperparathyroidism was caused by a solitary adenoma. Ninety-four per cent became normocalcemic following the operation. Consistent hypocalcemia requiring vitamin-D treatment occurred in 3%, and 2% had a persisting hypercalcemia or later recurrence. The therapeutic effect on the neuromuscular symptoms, constipation, anorexia, and renal stone formation was considered good or fair in most of the cases. Primary hyperparathyroidism in the elderly occurs with a high prevalence. It can be treated successfully by surgical therapy with a low cost of morbidity, mortality, and medical care.

In a well-defined geriatric population the prevalence of primary hyperparathyroidism was 1.5%. From a clinical material consisting of 400 patients treated surgically for primary hyperparathyroidism during a 10-year period 158 patients (38%) above the age of 64 were studied. Neuromuscular symptoms were present in 80%, renal insufficiency or kidney stones in each 16%, constipation and/or anorexia in 38%. 10% were considered clinically asymptomatic. In 80% the primary hyperparathyroidism was caused by a solitary adenoma. Normocalcaemia was achieved in 94%. Hypocalcaemia requiring vitamin D treatment occurred in 3%, and in 2% hypercalcaemia persisted or recurred. All of these had multiglandular parathyroid disease. The therapeutic effect of the surgical treatment was considered good or fair in most of the cases. No mortality occurred. Primary hyperparathyroidism occurs with a high prevalence in the elderly. It can be treated successfully by surgical therapy with a low cost of morbidity, mortality and medical care.
