In our hospital early neonatal hypocalcaemia is now the major cause of low serum calcium in the neonatal period. Over a 2-year period, only 2 cases of hypocalcaemic convulsions were seen in a total of 8700 deliveries, though 51 infants had early neonatal hypocalcaemia. All sick low birth-weight infants should have daily serum calcium estimations carried out. Calcium supplements should be consid...

OBJECTIVE To determine the risk of postthyroidectomy hypocalcaemia by measuring parathyroid hormone (PTH) level after thyroidectomy. STUDY DESIGN Cross-sectional study. PLACE AND DURATION OF STUDY Baqiyatallah Hospital, Tehran, Iran, from March 2008 to July 2010. METHODOLOGY All included patients were referred for total or near bilateral thyroidectomy. Serum Calcium (Ca) and PTH levels we...

OBJECTIVE To determine the validity of early (one hour postoperatively) parathyroid hormone (PTH) assay (² 10 pg/ml), keeping gold standard as the serum ionic calcium level, for predicting sub-total thyroidectomy-related hypocalcaemia and to calculate the sensitivity and specificity of latent signs of tetany. STUDY DESIGN Cross-sectional validation study. PLACE AND DURATION OF STUDY Departm...

Cockburn, F., Brown, J. K., Belton, N. R., and Forfar, J. 0. (1973). Archives of Disease in Childhood, 48, 99. Neonatal convulsions associated with primary disturbance of calcium, phosphorus, and magnesium metabolism. The biochemical relations in 75 newborn infants suffering from convulsions considered to be due to a primary disturbance of mineral metabolism have been studied. Hypocalcaemia was...

A 71 year old woman presented with hypocalcaemia in association with autoimmune haemolytic anaemia and pernicious anaemia. The hypocalcaemia resolved only when the haemolytic anaemia and pernicious anaemia were successfully treated. The possible pathogenic mechanisms are discussed.

BACKGROUND Hypocalcaemia after thyroidectomy is the most common postoperative complication, with a reported incidence from 0.5% to even 50% of the operated patients. Hypoparathyroidism could be a result of careless or inadequate preparation during the surgical procedure. There is a variety of proposed options for the prediction of the incidence of hypocalcaemia. The most effective of them are t...

OBJECTIVE After thyroidectomy hypocalcaemia is the most significant complication for clinicians. In this study, we investigated the factors associated with development of hypocalcaemia after thyroidectomy. MATERIALS AND METHODS We investigated the patients prospectively for age, gender, preoperative diagnosis, hormonal status, operative time, operating surgeon, existence of parathyroid gland ...

AIMS To investigate a population of individuals with 22q11 deletion syndrome for hypocalcaemia. METHODS A detailed clinical history enquiring into symptoms of hypocalcaemia and blood sampling to assess for hypocalcaemia and hypoparathyroidism, of patients outside the neonatal period known to have the 22q11 microdeletion from fluorescent in situ hybridisation studies was taken. RESULTS Sixty...

symptoms are mild, the hypocalcaemia temporary, and treatment is not required. In a few, those with renal disease, bone disease or steatorrhoea, the hypocalcaemia is likely to be severe and need treatment. The routine management of this type of patient has been described by Dent (1962). We have recently studied two patients who had generalised convulsions after parathyroidectomy despite this ro...
