Antacid bezoar in a premature infant.

A premature infant with severe enteroviral infection was treated with Maalox for gastric bleeding. Bezoars formed, which were shown to contain high concentrations of magnesium. An association between antacid administration and bezoar formation in neonates has been previously suggested but has not until now been clearly documented.

Serum and mononuclear cell potassium, magnesium, sodium and calcium in pregnancy and labour and their relation to uterine muscle contraction.

Thirty women in their third trimester of pregnancy (37-42 weeks), 40 women during and 72 h after labour and 18 non-pregnant controls were studied for changes in serum and mononuclear cell cation content, and their relationship to cervical effacement and intensity of pain as measured by plasma beta endorphin concentrations during labour. Serum magnesium fell from 0.95 +/- 0.

The effects of chromium supplementation on serum glucose and lipids in patients with and without non-insulin-dependent diabetes.

Seventy-six patients with established atherosclerotic disease were treated daily with either 250 micrograms of chromium orally as chromium chloride or a placebo for a period of 7 to 16 months (mean, 11.1 months). Serum chromium increased from 2.

Effects of hydrochlorothiazide, diltiazem and enalapril on mononuclear cell sodium and magnesium levels in systemic hypertension.

Sixteen patients (mean age 68 years) with mild to moderate hypertension were treated with either diltiazem or hydrochlorothiazide for 6 weeks, followed by enalapril for a further 6 weeks. A second group of 40 patients (mean age 71 years) was treated with either hydrochlorothiazide or enalapril for 12 weeks; nonresponders received both drugs for 8 weeks. Treatment with hydrochlorothiazide or enalapril resulted in a lowering of systolic and diastolic blood pressures, but diastolic pressure was lower in patients treated with enalapril (89 +/- 2 and 82 +/- 2 mm Hg, respectively; p less than 0.

Serum and intracellular electrolytes in patients with and without pain.

The effect of acute stress, with and without pain, on serum and mononuclear cell cation content was studied in 205 healthy women in their last trimester of pregnancy or during normal labour, in patients with acute medical conditions in which pain was or was not present, in acute surgical conditions, and immediately prior to elective surgery. In all subjects there was a fall in serum sodium, potassium, magnesium and calcium concentrations during stress, with an apparent shift into the intracellular space. An inverse correlation was present between the severity of pain and the fall in serum cations.
