Back pain is one of the chief complaints of the elderly. It may be either a chronic deep skeletal muscular pain or an acute circumscribed pain arising from nerve-root irritation. The main causes of back pain in older people are: 1) degenerative changes (spondylosis, osteoarthritis, ankylosing hyperostosis); 2) malignancy (multiple myeloma, metastases from carcinoma or lymphoma); and 3) metabolic disorders (osteoporosis, osteomalacia, chondrocalcinosis, Paget's disease). Mechanisms and variations are discussed in detail.

The coexistence of a myeloma and Paget's disease in the same patient is only rarely reported in the published literature. The frequency of such an association was studied when reviewing 3 cases observed by the authors: an IgG myeloma discovered following a spasmodic paraplegia in a patient with Paget's disease; a patient who was found to have a myeloma, a polynuclear neutrophil leukemia, and Paget's disease; and an IgG myeloma in a patient with probable localized Paget's disease. The incidence of the association myeloma-Paget's disease is much lower than that of sarcomatous degeneration. It should be determined precisely, however, as our future conception of the reciprocal relationship between the two diseases is greatly dependent on this information. Furthermore, the very few cases reported, and their lack of homogenicity, are the reasons why most authors feel that the association of myeloma and Paget's disease as pure coincidence. Many new cases, however, have been recently reported. The problem of the significance of the association of Paget's disease and macroglobulinemia or other monoclonal gammapathies has still to be solved.

The dosage of calcium ionized serum using a selective electrode, was performed in a series of controls and patients with osteo-articular diseases. Normal values were 43 mg/l between 20 and 50 years of age, and 41 mg/l after 60 years. The level of ionized calcium, when given as a percentage of total blood calcium, did not decrease with age (normal value : 44%). It was increased in hyper-parathyroidism, rhumatoid polyarthritis and lytic bone metastasis. It did not vary in Paget's disease, osteoporosis, osteomalacia, condensing metastasis, Kahler's disease and spasmophilia. The ionized calcium in definitely diminished in hypoparathyroidism.

The record and roentgen findings in a patient with Paget's disease with coexisting multiple myeloma have been presented. Their rare or even unique association is recorded to refresh ones recollection that patients with Paget's disease may be host to a second disease, which if recognized, may be of inestimable profit to the medical care and comfort of the patient.

The etiology of Paget's disease is just as doubtful in 1975 as it was in 1876 when Sir James Paget described the disease. The authors analyse the etiology on the basis of 100 personal cases and the literature. Although there are undoubtedly familial cases of the disease, investigation of the leucocyte grouping of 46 patients with Paget's disease did not reveal any correlation between occurrence of the disease and the HL-A antigens. Various pathological associations have been reported in the literature and were also found in this series. These associations were at the limits of coincidence (inflammatory rheumatism, diffuse chondrocalcinosis, multiple myeloma...). Metabolic changes (hyperuricaemia, hyperglycaemia, dyslipidaemia) did not appear to be more frequent than in control patients. Involvement of elastic tissue and the presence of pseudocrystalline inclusions in the osteoclasts constitute interesting points for discussion.

Salmon calcitonin, a polypeptide hormone secreted by the parafollicular C cells of the thyroid gland, lowers serum calcium levels by decreasing bone resorption and renal tubular calcium reabsorption. An analgesic action, possibly mediated via beta-endorphins, is also evident. In the past, parenteral formulations of salmon calcitonin have been used in the management of metabolic bone disorders, but their routine use has been limited by the inconvenience of this route of administration and by poor tolerability. The development of an intranasal preparation of salmon calcitonin will provide a more convenient means of administering the drug. In clinical trials published to date intranasal salmon calcitonin has been effective and well tolerated in small numbers of recently postmenopausal women at risk of developing osteoporosis, and in patients with established osteoporosis, Paget's disease, or osteoporosis secondary to corticosteroid usage, multiple myeloma or ovariectomy. For periods of up to 2 years the drug reduces bone resorption and improves bone architecture, relieves pain and increases functional status. Further research is needed to confirm longer term efficacy (in particular, effects on fracture rate), optimal dosage schedules and the role of intermittent and combination treatment regimens.

Osteocalcin, also called bone gla-protein, is a bone matrix protein synthetized specifically by osteoblasts. It circulates in blood where it can be assayed by the radioimmune method. We measured osteocalcin serum levels in 169 adult controls and 161 patients with different disseminated or localized bone diseases. The normal concentration of 6.2 +/- 0.2 ng/ml increases significantly with age. Serum osteocalcin levels are considerably increased in renal osteodystrophy (114 +/- 23 ng/ml) and to a lesser degree in primary hyperparathyroidism (15.9 +/- 2.8 ng/ml) and Paget's disease (11.4 +/- 0.9 ng/ml), all diseases characterized by increased bone turnover. High levels are also encountered in osteomalacia (9.7 +/- 0.9 ng/ml). Conversely, serum osteocalcin levels are significantly decreased in patients under long-term corticosteroid therapy (4.3 +/- 0.5 ng/ml); they remain normal in patients with bone myeloma and bone metastases under treatment. Finally, osteocalcin is normal in patients with osteoporosis, but its level reflects that of bone turnover as evaluated by iliac bone biopsy. The circulating osteocalcin therefore is the first specific and sensitive marker for bone turnover. Serum osteocalcin measurements make it possible to evaluate the osteoblastic bone formation without biopsy and should provide information on the effectiveness of drugs acting on the bone-forming process.

Results are presented of measurements of skeletal blood flow made in 80 patients with painful benign or malignant diseases of the skeleton, excluding patients with Paget's disease. In crush fracture osteoporosis, total bone blood flow was slightly lower than normal although skeletal perfusion was normal. High values of bone blood flow were seen in 14/20 patients with osteomalacia and 3/12 patients with primary hyperparathyroidism. Very high values, comparable to those seen in the most severely affected patients with Paget's disease, were seen in polyostotic fibrous dysplasia, 2 out of 4 cases of Engelmann's disease and 1 out of 3 cases of renal osteodystrophy. Results were less elevated in myositis ossificans, secondary skeletal involvement with breast and prostatic carcinomata, myelomatosis and sympathetic osteodystrophy.

Dichloromethylene diphosphonate (Cl2MDP) a potent inhibitor of osteoclast-mediated bone resorption, lowers serum calcium in hypercalcemia associated wit malignancies and with primary hyperparathyroidism, and reduces excess calcium mobilization from bone in multiple myeloma and in Paget's disease. We have evaluated the effectiveness of intravenously administered Cl2MDP in five patients with parathyroid carcinoma, a disorder characterized by severe hypercalcemia, very high parathyroid hormone (PTH) levels, and marked osteoclast-mediated bone resorption. All patients had biopsy-proved metastatic parathyroid carcinoma and hypercalcemia which persisted after multiple surgical procedures and other attempts at management. During a three-day observation period, each patients continued to demonstrate stable or progressive hypercalcemia despite infusion with saline solution and furosemide. Cl2MDP was administered over 2 hours at 2.5 mg/kg on day 1 and 5 mg/kg on days 2 through 7. Response was noted in all five patients; there was a gradual decline in the average serum calcium from 16.0 +/- 1.1 mg/dl (SEM) to 11.1 +/- 0.9 mg/dl by the eighth day (p less than 0.01). There were concomitant reductions in urinary calcium excretion, from 798 +/- 153 mg/g creatinine to 350 +/- 96 mg/g creatinine (p less than 0.05) and in the urinary hydroxyproline excretion, from 155 +/- 38 mg/g creatinine to 94 +/- 29 mg/g creatinine (p less than 0.02). Serum PTH levels remained markedly elevated (460 +/- 141 micrograms eq/ml to 493 +/- 169 micrograms eq/ml). In three patients, all indices returned to pretreatment levels by 10 days after the last infusion. In two of these patients there was a response to retreatment with Cl2MDP with a fall in calcium from 16.9 +/- 0.5 mg/dl to 12.4 +/- 1.5 mg/dl. There was no response in one patient. No adverse reactions to Cl2MDP were observed. The decrease in serum calcium and concomitant declines in urinary calcium and hydroxyproline suggest that Cl2MDP can effectively inhibit the excessive bone resorption associated with parathyroid carcinoma.
