Value of absent or retrograde end-diastolic flow in fetal aorta and umbilical artery as a predictor of perinatal outcome in pregnancy-induced hypertension.

There is insufficient data on the value of absent or retrograde end-diastolic flow (AREDF) in the fetal umbilical artery, descending aorta and aortic arch to predict perinatal outcome. In this prospective investigation, 65 pregnant women between 24 and 34 weeks' gestation with pregnancy-induced hypertension were studied by color Doppler echocardiography. Pregnancies leading to birth at or before 34.0 gestational weeks (23 with and 19 without AREDF) were included in the outcome analysis. Fetuses with AREDF were delivered at earlier gestational ages (p = 0.006). They had a higher incidence of gastrointestinal complications (p = 0.01), bronchopulmonary dysplasia (p = 0.03), intraventricular hemorrhage (p = 0.03) and vascular hypotension (p = 0.03) than those without AREDF. The presence of AREDF was associated with a mortality rate of 30%, whereas in fetuses without AREDF there was no mortality (p = 0.01). Using logistic regression and taking into consideration various perinatal factors, the presence of AREDF (p = 0.03) and early gestational age (p = 0.0001) were associated with serious neonatal diseases or death. A reverse diastolic flow in the aortic isthmus was registered in five fetuses; three died during the perinatal period and one was severely damaged. According to our results, AREDF, particularly with the appearance of reverse diastolic flow in the isthmus of the aortic arch, is a predictor of poor neonatal outcome.

Atrial natriuretic peptide and atrial pressures in newborns with transposition of the great arteries.

The relation of atrial pressure to atrial plasma concentration of atrial natriuretic peptide (ANP) was studied in four newborns undergoing catheterization because of transposition of the great arteries. In three patients, mean left atrial pressure clearly exceeded right atrial pressure (12 +/- 7 vs. 2 +/- 3 mmHg; mean +/- SD). In one patient mean atrial pressures were identical (4 mmHg). In all patients the ANP concentration in the left atrium exceeded that of the right (833 +/- 464 vs. 415 +/- 366 pg/ml; mean +/- SD). There was a significant (r = 0.97; p less than 0.01) correlation between pressure and ANP concentration in the left atria. In the right atria, no linear correlation existed between pressure and ANP concentration. ANP concentration in the left atrium decreased after a lowering of the left atrial pressure by atrial septostomy. In these patients, the left atrium seems to be the main source of circulating ANP.

Fibrosarcoma in a girl with celiac disease and IgA deficiency.

A case of abdominal wall fibrosarcoma in a 17-year-old girl with celiac disease and IgA deficiency is described. Celiac disease was putatively diagnosed with intestinal biopsy at the age of 15 years when she came for hospital investigations because of IgA deficiency and recurrent respiratory infections. The tumor occurred at the age of 17 years during the gluten challenge performed for final diagnosis of celiac disease. Surgical excision, irradiation, and chemotherapy were initially successful. After 7 months, however, the tumor recurred. Reoperation and a new course of irradiation therapy coinciding with the reinstitution of a gluten-free diet proved to be effective in tumor eradication. Nine years after the cessation of cancer treatment she is well and has two healthy children.

Extracardiac malformations associated with congenital heart disease.

The incidence of significant extracardiac malformations was determined in a combined clinical and autopsy study comprising 1000 infants and children with congenital heart disease treated and lost at the Children's Hospital in Helsinki. There were 567 boys and 433 girls. 1/4 of the children had a birthweight of 2500 g or less. 850 children were under 1 yr old. Death occurred during the 1st mth of life in 546 cases. Extracardiac malformations were encountered in 439 children. They were more common in girls than in boys. The incidence of associated malformations was comparatively high in infants with a low birthweight. The noncardiac anomalies were considered main causes of death in 1/3 of the cases. Extracardiac organs were involved in the following order of frequency: alimentary, skeletal, urogenital, central nervous and respiratory system. Of the main cardiac malformations, septal defects were associated with the highest and transposition of the great arteries with the lowest incidence of extracardiac anomalies. An accumulation of some defined noncardiac malformations was observed in patients with certain heart lesions.

Effect of seasonal variation in daylight on bilirubin level in premature infants.

The effect of daylight on the serum bilirubin level of preterm infants (birthweight less than 2500 g) during the first 10 days of life was studied in a district of Finland (Oulu, latitude 65 degrees ĺ) with large seasonal variations in the length of daylight (range 3 to 22 h). 86 preterm infants born consecutively during one calendar year were studied in incubators where they were completely exposed except for nappies. A significantly lower bilirubin value from the fifth day of life onwards was recorded ih the group of infants born during the light half of the year, compared with the infants born during the dark half of the year. Only 4 infants developed total bilirubin levels higher than 255 mumol/l in the "light group", as compared with 10 in the "dark group". 2 infants in the light group required exchange transfusion, while 4 in the dark group did. It is concluded than natural light conditions are of importance in the design of wards for newborn infants.
