Randomized Controlled Trial Clinical Trial
Influence of fluid regimens on perioperative blood-glucose concentrations in neonates.
Blood concentrations of glucose were measured during surgery and during the first 8 h after operation in 30 neonates undergoing major surgery during the first week of life. Fifteen of the neonates were given Ringer-acetate as the only crystalloid peroperative fluid; to the other 15, 10% glucose i.v. was administered during surgery. In the Ringer-acetate group, mean (SD) blood concentration of glucose increased from 3.1 (2.0) to 4.3 (2.4) mmol litre-1 during surgery. ⋯ Hypoglycaemia occurred in both groups, but more often in the group given Ringer-acetate only (3/15 vs 1/15). Hypoglycaemia was found only in neonates less than 48 h of age and during the first 1 h of anaesthesia only. Monitoring of blood concentrations of glucose and adjustment of the glucose infusion appears to be desirable during and after surgery in neonates.

Comparative Study
Carbohydrate tolerance improves with fasting in obese subjects with noninsulin-dependent (type II) diabetes.
To determine the effects of short-term fasting on carbohydrate tolerance, 10 obese women with noninsulin-dependent diabetes mellitus (NIDDM) were studied with meal tolerance tests before and after 3 days of fasting. After 3 days' fast, basal serum glucose declined from 15.2 +/- 0.9 to 7.5 +/- 0.7 mmol/L (273 +/- 17 to 135 +/- 13 mg/dL) (mean +/- SEM, p less than 0.001) and the glycemic response to the test meal (area under the glucose curve) improved by 31%. There were no changes in basal or postprandial insulin levels but a slight increase in serum c-peptide. ⋯ Those with lesser improvement in serum glucose showed overnight rises in serum glucose during the period of fasting (the dawn phenomenon), while those patients who normalized serum glucose showed a steady fall in serum glucose. This finding may help to predict the glycemic response to long-term calorie restriction. Carbohydrate tolerance improves in obese diabetic (NIDDM) women after 3 days of fasting, in contrast to the impairment of glucose tolerance seen in lean or obese nondiabetic subjects after fasting.(ABSTRACT TRUNCATED AT 250 WORDS)

[2,070 simultaneous determinations of blood glucose, glucosylated hemoglobin and fructosamine as index of metabolic control in 519 diabetic patients].
Two thousand and seventy simultaneous determinations of glucose, glucosylated hemoglobin (HbA1) and plasma fructosamine have been performed in 519 diabetic patients in order to obtain a follow up index and metabolic profile. This retrospective study points out the difficulty of achieving a good metabolic control in diabetic patients. Although the determination of plasma glucosylated proteins (HbA1 and fructosamine) has meant a great improvement in diabetic control, the study of the correlation of the above mentioned.

Case ReportsHypoglycaemia misdiagnosed by capillary glucose measurement.
The diagnosis of hypoglycaemia has become much easier with the introduction of bedside capillary glucose measurements which require a single drop of blood from a finger prick. However, such a diagnosis may be wrongly made in patients with poor peripheral circulation. This case report illustrates the common circumstances where misdiagnosis occurs A drop of venous blood should be used for bedside glucose measurement if the diagnosis is in doubt.
