Serum prolactin and cortisol concentrations after grand mal seizures.

Serial serum prolactin and cortisol levels were measured in five patients after a grand mal seizure and in four volunteers with simulated seizures. Single levels were measured after a witnessed seizure in 26 patients and in a matched control group. Significant increase in both prolactin and cortisol levels occurred after seizures. The change in cortisol level may reflect a non-specific stress response, but the increase in prolactin levels could not be accounted for on this basis, and probably indicates an alteration in hypothalamic neurotransmitter activity during the seizure. These findings may have clinical value in the diagnosis of epilepsy.

Haemolytic anaemia of pregnancy.

Haemolytic anaemia apparently induced by pregnancy is reported in an otherwise healthy woman, with a negative family history. Folate deficiency, haemoglobinopathies, enzymopathies, hereditary spherocytosis, paroxysmal nocturnal haemoglobinuria, interstitial haematomata, hypertensive toxaemia, auto-immunity and infections were excluded. The autohaemolysis test showed increased lysis in the presence of added glucose. This abnormality was corrected by insulin when excess glucose was present, but not by insulin alone. It is suggested that this patient's erythrocytes may have been altered by placental lactogen and/or prolactin in such a way as to make them abnormally dependent on insulin for the uptake of glucose.

Adrenocortical suppression in workers manufacturing synthetic glucocorticoids.

A man who had worked for 16 years in the manufacture of a potent corticosteroid was found to be suffering from chronic adrenocortical insufficiency attributed to chronic absorption of the glucocorticoid. Eleven other symptom-free workers were therefore screened. Two of these workers, like the first patient, gave grossly abnormal responses to the Synacthen (tetracosactrin) test; one had been employed for only seven months. All 12 men had facial plethora, suggesting absorption of the drug in spite of their having adhered to the safety precautions. All workers manufacturing potent steroids should therfore be screened regularly by measurement of their plasma cortisol concentrations and should be moved regularly to processing other drugs.
