Full-field visual evoked potentials and visual information processing were measured in 16 normal, healthy subjects during a hyperinsulinaemic clamp. A randomized cross-over design was used across three conditions: hypoglycaemia and caffeine; hypoglycaemia and placebo; and euglycaemia and caffeine. The latency of the P100 component of the pattern-reversal visual evoked potential increased signif...

OBJECTIVE To examine the traditional view that unawareness of hypoglycaemia and inadequate hypoglycaemic counterregulation in insulin dependent diabetes mellitus are manifestations of autonomic neuropathy. DESIGN Perspective assessment of unawareness of hypoglycaemia and detailed assessment of autonomic neuropathy in patients with insulin dependent diabetes according to the adequacy of their ...

Neonatal hypoglycaemia (blood glucose smaller than 20 mg/100 ml) occurred in the first 6 hours of life in 25 of 34 infants born to diabetic mothers receiving insulin. Despite severe hypoglycaemia (blood glucose smaller than 10 mg/100 ml) in 17, clinical features of hypoglycaemia were absent in all but 2. Hypoglycaemia was not related either to the level of plasma insulin in cord blood, determin...

The incidence of hypoglycaemia is greatest in the neonatal period, and the condition is usually associated with "small for dates" infants, although rare causes have been described.' Persistent neonatal hypoglycaemia, however, is usually caused by endocrinopathies or disorders of hepatic metabolism.2 We present some ofour experience of endocrine disease presenting as neonatal hypoglycaemia as th...

A patient with severe hypoglycaemia complicating cerebral malaria is reported. No other recognized cause of hypoglycaemia was detected during life or at autopsy. This case adds to the existing evidence that, through several possible mechanisms, cerebral malaria can give rise to life-threatening hypoglycaemia.

OBJECTIVE To analyse first-day-of-life glucose levels in infants of women with gestational diabetes (GDM) and the influence of maternal, gestational and peripartum factors on the development of neonatal hypoglycaemia. STUDY DESIGN Prospective cohort study including newborns of GDM mothers. Capillary blood glucose (CBG) was measured serially on the first day of life. CBG values were defined as...

Hypoglycaemia presents important diagnostic and therapeutic problems. Severe and repetitive hypoglycaemic episodes without treatment may be difficult to explain. Failure to identify factitious hypoglycaemia may lead to laparotomy or pancreatectomy [1, 2]. To estimate the prevalence of factitious hypoglycaemia due to sulphonylurea drugs in patients with unexplained severe hypoglycaemia, we condu...

AIMS To test the hypothesis that dipeptidyl peptidase-4 inhibition in C-peptide negative Type 1 diabetes would reduce glucose variability and exposure to hypoglycaemia and therefore may indirectly enhance counter-regulatory responses to subsequent hypoglycaemia. METHODS We conducted a 12-week double-blind, randomized, placebo-controlled crossover study. The study was conducted in a tertiary h...

Cotrimoxazole is a commonly used antimicrobial agent which is traditionally indicated in the management of pneumocystis infection of which HIV and immunosuppressed individuals are at high risk. Furthermore, it can be used on the long term for prophylactic indications. Hypoglycaemia following commencement of cotrimaoxazole is a rare adverse effect which was first described in 1988. We describe a...

Factors responsible for spontaneous hypoglycaemia were investigated in 23 gastrectomy patients and two patients with vagotomy and pyloroplasty. Plasma insulin and capillary blood glucose levels were followed after giving 175 ml of 50% glucose orally. In gastrectomy patients a significant correlation was found between the height of the peak blood glucose and insulin levels for the same individua...
