Four women presented with symptomatic hypercalcaemia and raised concentrations of serum parathyroid hormone (PTH). In each case, serum calcium returned spontaneously to normal. In two patients serum PTH also fell to the normal range and biochemical relapse has not occurred despite prolonged follow-up. In the others, serum PTH remained elevated and subsequent symptomatic hypercalcaemia necessita...

Primary hyperparathyroidism (PHPT) can cause hypercalcaemia secondary to a pathologically high secretion of parathyroid hormone. Rarely this can first manifest as acute psychosis. It is imperative to exclude organic causes of psychosis before labelling the psychosis as primarily psychological. If hypercalcaemia is revealed, investigation is required to elucidate the underlying cause whilst inst...

The combination of hypercalcaemia, hypercalciuria, and nephrocalcinosis with and without renal impairment is rare in paediatric clinical practice. However, this constellation of findings has been reported in three children with trisomy 21, but the absence of detailed nutritional data has failed to clarify the underlying pathogenesis. This report describes a 4 year old girl with trisomy 21 who w...

Serum calcium was studied serially in 94 patients with active pulmonary tuberculosis. An equal number of ageand sex-matched patients with chronic obstructive pulmonary disease were controls. Seventy patients in the study group were normocalcaemic and 10 were hypercalcaemic. These 10 were on a higher supplement of vitamin D than the 70 normocalcaemic patients. There was a positive correlation be...
