Changes in blood pressure during the first year of life.

Changes in blood pressure during the first year of life were investigated in a one-year follow-up study. The blood pressures were measured at the age of one day from 245 newborns, at the age of four or five days from 224 infants, at the age of four months from 105 infants, and at the age of one year from 68 infants. Blood pressure increased considerably during the first five days. The increase of mean systolic blood pressure was markedly bigger, from 59 to 90 mmHg, than that of mean diastolic blood pressure, which was from 43 to 55 mmHg. The correlations of blood pressure were calculated with prenatal history, physical measurements and parental blood pressure. Significant correlations were found with physical factors but not with the prenatal history or parental blood pressure. The tracking of the blood pressure was not good. The distribution of the blood pressure values was normal. It is concluded that for the time being there are no reliable predictive factors to hypertension which could be found in early infancy.

Central nervous system involvement in severe arterial hypertension of childhood.

The case histories of 125 children with hypertension and no apparent primary CNS disease were analyzed for neurological symptoms or complications. Eleven children had neurological symptoms of high blood pressure. In only one of these patients was the diagnosis of arterial hypertension made before the observation of the neurological findings. The symptoms were severe headache in eight children, convulsions and coma in four, hemiplegia in two, and impaired vision and apraxia in one child. Symptomatology was rapidly reversed by antihypertensive treatment in four children, while six had long-term stigmata and one child died in hypertensive crisis. Because elevated arterial pressure can cause severe neurological disease, routine blood pressure measurement in children--especially those with neurological symptomatology--is stressed.

The radiological evaluation of children with hypertension.

The value of radiological examinations in hypertension was analyzed in a series of 44 children. An i.v. urography had been performed in 43 cases with a pathological finding in 19 (44%). Renal angiography, employed in 19 cases, revealed abnormal findings in 12 (63%) patients. Micturating urethrocystography performed in 16 children gave no additional important information. The only complication noted was thrombosis of the femoral artery subsequent to renal angiography in one child less than one year of age. The diagnosis of hypertension based mainly on the i.v. urography in 12 cases but the renal angiography gave additional important information in 6 children. One child with obstructive hydronephrosis was also found to have a renal artery stenosis at renal arteriography. Based on these results, and particularly because secondary hypertension may frequently be treated surgically, we consider extensive radiological investigation with renal angiography is mandatory before receiving a final diagnosis of essential hypertension, and before starting long-term treatment.

Prediction of vesico-ureteral reflux in children from intravenous urography films.

Intravenous urography and voiding urethrocystography were performed on 255 children with urinary tract infection. Eighty-six (34%) of these children had some kind of abnormality of the urinary tract. Vesico-ureteral reflux was observed to 96 ureters (19%) in 69 children (27%). The prediction of vesico-ureteral reflux by two radiologists from urography films only gave 46 (48%) and 51 (53%) false negative results respectively. In cases of clinically important reflux (III--V degrees), however, the rate of false negative predictions was 0/18 and 1/18 (6%) respectively. The rate for false positive predictions were 45/413 (11%) for both radiologists. In view of the number of pathological findings in this series i.v. urography is recommended as a routine in children undergoing urological work-up after their first urinary tract infection. As the clinically important vesico-ureteral reflux seems to be predictable from urography films alone, voiding urethrocystography seems not to be justified in children with negative i.v. urography, and can be postponed and carried out later if the urinary tract infection recurs.

A survey of 164 Finnish children and adolescents with hypertension.

A retrospective analysis was performed on 164 children and adolescents with persistent hypertension. Among the unselected 115 patients with hypertension seen within the last three years 47 (41%) exhibited renal disease, 37 (32%) coarctation of the aorta, 10 (9%) miscellaneous associated causes and 21 (18%) no associated cause (essential hypertension). A substantial number, 53/164, had a primary disease potentially curable by surgery, and in 37 patients the blood pressure was normalized postoperatively. The outcome depended mostly on the basic disease and the availability of chronic hemodialysis. 11/164 children have died, all because of terminal basic disease, and one with simultaneous hypertensive crisis. We thus recommend a thorough investigation in the case of a child with persistent hypertension.

Is there bacteremia after suprapubic aspiration in children with urinary tract infections?

It has been shown that bacteremia may occur after bladder puncture in animals. Whether this also happens in man is not known. Thirty-three patients who were suspected to have urinary tract infection were examined for bacteremia after suprapubic bladder puncture. Of these children 19 had infection. There was no positive blood culture in any of these cases after suprapubic bladder puncture.

Nutrient intake and blood lipids in children.

Nutrient intake and serum total cholesterol (C T), serum high density lipoprotein cholesterol (HLD), triglycerides (TG) and fatty acids were evaluated from 692 3-year, 8-year and 12-year-old children in different areas in Finland. Serum/plasma TC concentrations varied from 4.8 to 5.0 mmol/l, HDL from 1.3 to 1.5 mmol/l and TG from 0.70 to 0.87 mmol/l. 12-year-old boys consumed significantly more energy than girls at the same age. In the 8-year-old boys the quality of fat used on the bread and quality of milk drunk influenced on the serum fatty acid composition, the proportion of linoleic acid being greater in those children who used margarine and/or low fat milk. The 3-year-old children at the highest quartiles of TC concentration used less wheat products and their intake of riboflavin was less than children in the lowest quartile. HDL concentration was associated with the intake of thiamine. The 12-year-old children having their TC concentrations in the highest quartile used more saturated fats and got more saturated fatty acids than children in the lowest quartile. The higher the sugar consumption and sucrose intake were, the lower was the HDL concentration. The prevalence of obesity increased with the age, being 0.5%, 5.0% and 8.5% in the 3-year, 8-year and 12-year-old children respectively. Urban children were more commonly obese than rural children, the prevalence being 8.0% versus 2.2% (p less than 0.01).
