The role of dialysis in the treatment of patients with severe
hypercalcemia
is uncertain. The fourteen previously reported cases of
hypercalcemia
treated with either peritoneal or hemodialysis have been reviewed. Two additional patients treated with hemodialysis are described in this report. Because the use of large volumes of intravenous fluids was contraindicated, each of the patients received a low calcium bath (0-1 mEq calcium per liter) hemodialysis for three and a half hours. After dialysis, the serum calcium fell to normal in both and remained normal thereafter with treatment of the underlying disease (multiple myeloma in one and vitamin D intoxication in the other). Hemodialysis can clear up to 682 mg of calcium per hour as compared to 124 mg per hour for peritoneal dialysis and 82 mg per hour with forced saline diuresis. Low calcium bath hemodialysis is indicated when the presence of renal and/or
cardiac failure
prevents the administration of large volumes of intravenous fluids to hypercalcemic patients.

A 43-year-old man with alopecia maligna was treated for 4 weeks with a total of 130 mg vitamin D3. Two weeks later, after intensive exposure to the sun, he developed a hypercalcaemic crisis and died 5 weeks later of acute
cardiac failure
. The
hypercalcaemia
proved treatment-resistant despite good diuresis. Causes other than vitamin D intoxication were excluded clinically and on histopathological investigations. It is suggested that vitamin D should be administered only on the strictest indications and with regular control of the patient.

Repeated efforts to induce beriberi heart disease by experimental thiamine deficiency (B1d) have failed in many species. To test the hypothesis that magnesium deficiency (Mgd) might be the cofactor necessary for
heart failure
, 10-week-old Syrian golden hamsters were divided into four groups-control (C), B1d, Mgd, and combined MgB1d-and were fed the diets ad libitum for 3 weeks. On day 21, animals were studied under intraperitoneal pentobarbital anesthesia (50 mg/kg). Electrocardiograms were taken and right and left ventricular pressures were measured by transthoracic needle puncture. Cardiac output was measured by the direct Fick method. The complete study was performed in 9 C, 13 B1d, 9 Mgd, and 14 MgB1d animals. B1d was proven by low red blood cell transketolate high B1 pyrophosphate effect, and was accompanied by tachycardia and
hypercalcemia
. B1 did not differ from C in any other parameter. Mgd was characterized by hypomagnesemia,
hypercalcemia
, prolongation of the PR interval, widening of the QRS interval, low O2 consumption, low cardiac output, and increased heart weight to body weight ratio (HW/BW) as compared to control. No differences were observed in right and left ventricular pressures or peak /dt. MgB1d was characterized by hypomagnesium,
hypercalcemia
, low red blood cell transkeotlase, and high B1 pyrophosphate effect. MgB1d minimized the deleterious effects of Mgd: animals were more active and the mortality was low, the PR interval remained normal, the QRS interval widened significantly less, cardiac output remained normal, and HW/BW increased significantly less. Although, once again, beriberi heart disease was not produced, B1d appeared to exert a protective effect upon the Mg-deficient myocardium.

Severe cardiac arrhythmias (Lown class IVa), rapid loss of physical capacity and dyspnoea on the slightest exertion occurred in a 55-year-old man with idiopathic dilated cardiomyopathy. In the preceding year he had recurrent diarrhoea and lost 23 kg in weight. He was found to have
hypercalcaemia
(3-3.2 mmol/l). The
heart failure
significantly improved under treatment with twice daily 12.5 mg captopril, 100 mg spironolactone daily, furosemide 40 mg twice daily, and digitoxin 0.07 mg daily. The arrhythmia responded to verapamil 80 mg and quinidine 160 mg, both drugs three times daily. Primary hyperparathyroidism was found to be the cause of the
hypercalcaemia
(parathormone 84 pmol/l). After the parathyroid adenoma had been removed the patient's condition again improved markedly. There were only rare monotopic extrasystoles, cardiac size regressed, and diuretics were no longer necessary. His medication at present is verapamil (80 mg three times daily), captopril (12.5 mg three times daily) and digitoxin (0.07 mg daily). It is concluded that the
hypercalcaemia
influenced the severity of the cardiomyopathy. It would seem that both intra- and extracellular calcium homoeostasis is of great importance in dilated cardiomyopathy.

46-year-old male patient was born in Niigata Prefecture and thereafter lived in Tokyo. In late January 1985, he noticed swelling of the bilateral inguinal lymph-nodes followed by fever and lumbago. In February, he consulted a local doctor and hepatosplenomegaly, marked leukocytosis and renal dysfunction were pointed out and he was referred to our hospital on February 22nd. The clinical laboratory data on admission were as follows; WBC 23,200/microliter, serum-Ca 18.4 mg/dl, BUN 85.3 mg/dl, creatinine 5.4 mg/dl, antibody to ATLV x160. ATL was diagnosed by biopsy of lymph nodes and examinations of peripheral blood and bone marrow hemogram. Remission was achieved in March by the treatment with adriacin. Renal failure and
hypercalcemia
also improved. However his respiratory dysfunction gradually worsened. The chest radiographies++ showed pulmonary edema, although there was no clinical evidence of
heart failure
. When his condition became stable, TBLB was performed and revealed extensive deposition of calcium along alveolar septae, suggesting that pulmonary edema was induced by the metastatic calcification of the lung. After the second treatment for ATL, he died of pneumonia. The autopsy showed calcium deposition not only in the lung but in pyramids of the kidney and in sub-serous layer of the small intestine. There was no tumor cell invasion into the bone or parathyroid gland. High urinary c-AMP together with normal levels of PTH suggested that the
hypercalcemia
in this case was induced by PTH-related protein. It was concluded that careful treatment for
hypercalcemia
is important as regards the occurrence of pulmonary edema.

We describe a patient with CML who developed
hypercalcemia
in his course of blast crisis. A 25-years-old man was diagnosed as CML with priapism in April 1985, and controlled with BHAC-DVP, VMP, busulfan therapy. In December 1987, he readmitted to our hospital with abdominal pain. Investigations at that time showed: white blood cell count 11600/microliters (blast cells 9%); hemoglobin 8.4 g/microliters; platelets 19.0 X 10(4)/microliters; serum calcium 13.2 mg/dl; BUN 44 mg/dl; creatinine 2.7 mg/dl. Treatment with predonine, 6-MP and vincristine was begun. But serum calcium level rose gradually up to 16.5 mg/dl. So we tried middle dose Ara-c therapy, serum calcium decreased to 6.8 mg/dl. At once he was in a chronic phase, but he relapsed and died of
heart failure
. Necropsy showed extensive leukemic blast-cell infiltration of the bone marrow, liver, spleen, lung, and kidney. The cause of
hypercalcemia
in our case was suspected of local osteolytic
hypercalcemia
, because multiple bone destruction was found.

A 57-year-old female was admitted to our hospital with general lassitude, loss of appetite, nausea, upper abdominal pain, thirst, polydipsia and polyuria. On admission, she had an asymmetrical pear-shaped tumor in the right supraclavicular region and severe
hypercalcemia
. Plasma C-PTH was elevated to 22.72ng/ml. Plasma calcitonin was also elevated to 336 pg/ml. She died of respiratory and
cardiac failure
of two weeks after admission without any positive response to the treatment, including hemodialysis. Pathohistologically, the tumor was a parathyroid adenoma. The concentrations of C-PTH, intact PTH and calcitonin in the tumor tissue were markedly high: 4.56 micrograms/g wet, 13.9 ng/g wet and 50.7 ng/g wet, respectively. Immunohistologically, the tumor cells and the fibrous stroma were stained strongly positive to rabbit anti-human calcitonin antibody and rabbit anti-human N-PTH antibody by indirect immunoperoxidase staining. Calcitonin-producing tumors, except for medullary thyroid carcinoma are rarely reported. To our knowledge, this is the first report of such a calcitonin-producing parathyroid adenoma associated with primary hyperparathyroidism.

The pathogenesis, clinical features, indications for therapy, and current pharamacologic management of Paget's disease are reviewed. Paget's disease is a bone disorder of unknown etiology primarily affecting the elderly. Overactive bone resorption leads to the accelerated formation of disorganized, weak bone. Pain and fractures are common clinical features. Neurologic, cardiovascular, metabolic, and neoplastic complications are also reported. Because most patients are asymptomatic, the disease is often detected during routine roentgenography or laboratory tests. Primary indications for pharmacologic intervention include bone pain, neural compression, immobilization
hypercalcemia
or hypercalciuria,
cardiac failure
, and orthopedic surgery. Recurrent or non-healing fractures and rapidly progressing complications are additional indications. Drugs used in the management of Paget's disease include calcitonin, etidronate disodium, and plicamycin. Although these agents are efficacious, each has disadvantages. Clinical resistance to animal calcitonins may develop, and the cost of therapy may be prohibitive. Etidronate may induce ostemalacia. The use of plicamycin is limited by potentially severe toxicities. Dichloromethylene and aminohydroxypropylidene are promising diphosphonate compounds but are still investigational In those patients who are unresponsive to single-agent regimens, combination therapy may prove effective. Although many patients with Paget's disease do not require pharmacologic therapy, calcitonin and etidronate are the agents of choice when it is indicated.

Osteitis deformans is a focal disease of the osteoclasts characterised by increased bone resorption subsequently followed by increased bone formation leading to abnormal bone. A viral etiology seems increasingly probable, but remains unproven. 5-30% of the patients present with symptoms such as pain, deformity and fracture. Hearing loss, nerve- or root-compression, arthrosis and hyperuricaemia may complicate the disease while malignant degeneration,
hypercalcemia
and high output
cardiac failure
are rare. The diagnosis is based on X-ray findings but biopsy may be necessary in selected cases. The extent of the disease is revealed by bone scintigraphy and the activity of the disease reflected by urine hydroxyproline excretion and serum alkaline phosphatase.

The development of specific inhibitors of bone resorption has revolutionized the treatment of Paget's disease. The diphosphonates, the calcitonins, and mithramycin are capable of inducing marked suppression of disease activity for prolonged periods as judged by biochemical, kinetic, and histologic techniques. Whereas the effects of the calcitonins and mithramycin persist only for the duration of treatment, diphosphonate treatment consistently results in a reduction of disease activity for many months or even years after stopping treatment. The question arises whether the long-term control of the disease activity confers significant clinical advantages to the patient. Relief of bone pain, spinal neurologic syndromes, immobilization
hypercalcemia
, and high-output
cardiac failure
are related to the degree of biochemical control attained by treatment. New bone formed during treatment is lamellar and radiologic progression of disease is favorably modified. It is not yet known whether long-term treatment will decrease bone enlargement and deformity or reduce the risk of fracture.
