A 46-year-old female presented with a three year history of progressive weakness. Asymptomatic apart from proximal myopathy, multi channel screening and radiological features indicated primary hyperparathyroidism with severe metabolic bone disease. Removal of a parathyroid adenoma led to improvement of muscle strength and regression of bony and metabolic changes.

A report of a case of primary hyperparathyroidism presenting as spinal cord compression due to a brown tumour of the vertebra is presented. Coexisting chrondrocalcinosis illustrates one of the several radiological features seen in hyperparathyroidism.

This case of primary hyperparathyroidism presented several unusual features: (1) The only presenting symptoms were two gingival giant cell lesions (brown tumors), (2) Bone changes occurred early in the disease, but apparently affected only the mandible and maxilla, (3) No renal disease could be detected. The diagnosis, treatment and postoperative course of this unusual case has been described.

Metastatic calcification has been visualised on bone scan in many hypercalcaemic states. This report illustrates the phenomenon occurring in a patient with primary hyperparathyroidism and its subsequent disappearance after therapy.

Simultaneous determinations of serum total calcium(TOCa), protein corrected total calcium (TOCac), ultrafiltrable calcium (UFCa) and ionised calcium (Ca++) were undertaken in 63 controls and in 76 patients with primary hyperparathyroidism. Raised levels of Ca++ were used as one criterion of the diagnosis which was confirmed by operation in all. For the purpose of estimating the relative value of TOCa and TOCac in the detection of mild hyperparathyroidism we selected all patients with TOCa values below 3.00 mmol/l (n = 46). As a group these patients turned out to be mildly hypoproteinaemic (p less than 0.01), probably because of high age and complicating conditions. Further subdivision of this group into frank hypercalcaemia, borderline hypercalcaemia and normocalcaemia was undertaken according to the respective 99% and 95% confidence limits of normal. Twenty-seven patients were classified as frankly hypercalcaemic by TOCa as well as by TOCac. The distribution of the remaining 19 patients within the three categories was 1:6:12 as judged from TOCa while TOCac gave a better distinction from normal, 9:4:6 (p less than 0.01). This compared well with the classification obtained by UFCa, 10:5:4. It is concluded that TOCac is definitely advantageous to TOCa in the detection of hypercalcaemia in mild primary hyperparathyroidism.

Forty-two patients with primary hyperparathyroidism were seen in Auckland Hospital between 1971-1976. These patients were reviewed as to age, sex, mode of presentation, pathology and location of lesions. All were treated surgically. There were two deaths due to severe hypercalcaemia. The value of parathyroid hormone assay and neck vein catheterisation is assessed. The practical aspects of neck exploration for hyperparathyroidism are outlined. The two problems of the treatment of chemical hyperparathyroidism and the recognition and treatment of parathyroid hyperplasia are discussed.

Severe osteomalacia due to causes other than malabsorption and, where renal function was impaired, disproportionate to the degree of renal failure, is described in 15 adults. Only one was younger than 46 years, the median age being 59 years. The diagnosis was not made for months in most patients. After investigation, the patients were grouped as follows: nutritional three cases, "renal" six cases, hypophosphataemia three cases, neurofibromatosis and primary hyperparathyroidism one each. The last patient was poorly nourished and had taken anticonvulsants and analgesics. Most patients responded well to treatment with calciferol. These cases indicate the need to be aware that osteomalacia may occur in previously healthy middle-aged or elderly subjects.

Forty cases of primary hyperparathyroidism presenting over a 15 year period, have been reviewed. The disease was equally prevalent in both sexes with highest incidence in the sixth decade. Most patients presented with renal colic or calculi (73 percent) and skeletal disease was found in only 13 percent. A single parathyroid adenoma was found in 32 cases and hyperplasia was diagnosed in only two cases. Follow-up questionnaires were sent to 32 patients, and in 27 of these a full clinical and laboratory assessment was undertaken. Of 26 patients with renal colic preoperatively only six continued to experience colic one year after parathyroid surgery. Thirty percent of all patients were hypertensive preoperatively, and in only two patients did blood pressure normalise after surgery. Fourteen of 27 patients followed-up were found to be hypertensive. A highly significant fall was noted in serum calcium, chloride, alkaline phosphatase and urine calcium excretion postoperatively. Recurrence of the disease was low and less than 8 percent in this series. The low incidence (1 per 10 000 population per year) suggests that primary hyperparathyroidism is under diagnosed in the Christchurch community.

Pancreatitis has been described previously following renal transplantation, but not in association with chronic renal failure. Analysis of 168 patients with renal transplants revealed five who developed pancreatitis, three of whom died. All five were on treatment with prednisone and azathioprine. Four patients were seen with definite attacks of pancreatitis and chronic, stable renal failure from a variety of causes. None had received immunosuppressive agents, prednisone nor thiazide diuretics, but two were on regular frusemide. One patient was on maintenance dialysis, which could not be related directly to the pancreatitis. In either group alcohol ingestion, cholethiathiasis, or hypercalcaemia was not a factor. This diagnosis of pancreatitis was established on clinical grounds and serum amylast levels of greater than 900 iu/1. Similar serum amylast elevation was not found ina random group of patients with chronic renal failure. Hyperlipidaemia was not present in any patient with pancreatitis. Although hypercalcaemia and primary hyperparathyroidism was not found in the transplant and non-transplant subjects, elevated serum parathormone levels have been described in uraemic patients with normocalcaemia. Hyperparathyroidism may be a factor in the development of pancreatitis in reanl failure. Pancreatitis carries a significant mortality risk in renal transplantation. The four non-transplanted patients have survived, despite recurrent attacks of pancreatitis.

Hypercalcemia after renal transplantation (post-T hypercalcemia) has been detected in 29 (16.7%) of 174 long-term survivors. The mean time of onset of hypercalcemia was 69 days after renal transplantation (range 3-210). In 18 patients the hypercalcemia was mild and resolved spontaneously (transient) from 2-65 months (mean 19) after onset. In 4 patients serum calcium normalized concurrently with rejection episodes. In 7 patients the hypercalcemia was more pronounced (permanent), being terminated by subtotal parathyroidectomy in 5 and persisting in 2 recipients. The hypercalcemia was asymptomatic except in one patient, who developed calculi in the graft and a fall in graft function, all of which disappeared after parathyroidectomy. At operation the parathyroid glands showed hyperplasia, except in one case with an adenoma in one of the hyperplastic glands. Serum phosphorus was markedly decreased, to the same extent in transiently and permanently hypercalcemic recipients. Serum parathyroid hormone (S-PTH) was increased in all of 5 patients with permanent and in 3 of 8 with transient post-T hypercalcemia. In normocalcemic and in transiently hypercalcemic recipients the mean S-PTH was identical, but significantly lower than in the permanently hypercalcemic recipients. S-PTH was suppressed to the same extent during an i.v. calcium infusion in patients with post-T hypercalcemia and with primary hyperparathyroidism.
