OBJECTIVE Hypercalcaemia is an important cause of increased morbidity and mortality in patients with parathyroid carcinoma. Surgical resection is the mainstay of treatment but, equally, managing hypercalcaemia is of paramount importance. At present, few therapies have been shown to be effective in the most severe cases. This report describes the efficacy of denosumab in a patient with parathyro...

Immobilization-related hypercalcaemia is an uncommon but important condition being associated not infrequently with both urolithiasis and osteoporosis. In this study 5 patients who had been immobilized for a mean of 3 months and had a mean adjusted serum calcium of 3.15 mmol/l were treated with doses of intravenous pamidronate ranging between 10 mg and 45 mg. All patients became normocalcaemic ...

Peptic ulcer disease may be a manifestation of symptomatic primary hyperparathyroidism. A case of an intractable complicated peptic ulcer disease secondary to hypercalcaemia from multiple endocrine neoplasia type 2A is presented. Hypercalcaemia should always be excluded as a cause of recurrent, or complicated peptic ulcer disease.

A 47-year-old woman presented with extreme hypercalcaemia due to a parathyroid carcinoma. An electrocardiogram which was recorded when the hypercalcaemia was associated with hypokalaemia showed absence of the ST segment, prolonged T wave, a shortened QTac interval and prominent U waves.

Two thyrotoxic patients with significant hypercalcaemia are described. The hypercalcaemia failed to suppress with hydrocortisone, propranolol and calcitonin but serum calcium fell rapidly to normal with carbimazole treatment. Both patients were subsequently treated surgically and at operation no evidence of parathyroid disease was found. Thyroid disease must be controlled before co-existing par...

1 Department of Medical Oncology, We report a case of inoperable metastatic parathyroid carcinoma involving lifethreatening hypercalcaemia that failed to respond to standard therapy. Our review of available therapeutic modalities showed a paucity of evidence to guide management of patients with these rare tumours. This is the first report of the treatment of malignant hypercalcaemia secondary t...

A patient with a phaeochromocytoma associated with hypercalcemia is described. The hypercalcaemia was corrected by removal of the phaeochromocytoma. Parathyroid hormone-like peptide was isolated from the tumour suggesting that ectopic parathyroid hormone production from the phaeochromocytoma was the explanation of the hypercalcaemia.

Background The overall incidence of Pneumocystis jirovecii pneumonia (PJP) in solid organ transplant recipients is 5-15%. A timely diagnosis of PJP is difficult and relies on imaging and detection of the organism. Methods We present a case series of four patients displaying hypercalcaemia with an eventual diagnosis of PJP and document the management of the outbreak with a multidisciplinary te...

A study is reported of the estimation of plasma calcium fractions and the calcium-binding affinity of plasma proteins in a total sample of 59 people, which included 29 normal subjects and 30 patients with either hypercalcaemia or hypocalcaemia. It was demonstrated that when the sample was considered as a whole there was a significant correlation between the total plasma calcium concentration an...

RATIONALE Hyperthyroidism is one of the major clinical causes of hypercalcaemia, however, hyperthyroidism-related hypercalcemic crisis is rare, only 1 case have been reported. The potential mechanisms are still not too clear. It may be related that thyroid hormone stimulate bone turnover, elevate serum calcium, increase urinary and fecal calcium excretion. PATIENT CONCERNS A 58-year-old femal...
