First line screening for pheochromocytoma, as recommend by Endocrine Society guidelines, is to determine plasma free or urinary fractionated metanephrines. We routinely offer the latter. Although negative results rule out pheochromocytoma, it is not uncommon to see borderline results which require further investigation. In this situation we have historically relied on the measurement of plasma catecholamines in the clonidine suppression test (CST). Plasma metanephrines, howeve...

There is evidence that an unbalanced maternal diet, combining a high ratio of protein to carbohydrate with low intakes of folate and green vegetables imposes a metabolic stress on the mother and fetus leading to fetal growth retardation. Because recent studies have shown that high protein maternal diets are associated with raised offspring blood pressure, we have assessed whether this form of unbalanced maternal nutrition is also associated with glucose intolerance.<p clas...

Background: Consumption of a high-meat, low carbohydrate diet in late pregnancy is associated with fetal growth restriction, and raised blood pressure and glucose intolerance in the offspring. In a recent study in Motherwell, Scotland, where pregnant women had been advised to eat one pound (0.45 kg) of red meat per day during pregnancy and to avoid carbohydrate-rich foods, we found elevated fasting plasma cortisol levels in men and women whose mothers reported higher protein c...
