The incidence and prevalence of inflammatory bowel disease were estimated in all children less than 16 years of age living in the city of Göteborg and in three countries in South-Western Sweden, from 1983 to 1987. One hundred and thirty-two patients were classified according to set criteria into one of four diagnostic categories: ulcerative colitis, Crohn's disease, probable Crohn's disease and indeterminate colitis. The crude incidence of inflammatory bowel disease was 5.3 per 100,000 children per year and the prevalence 21.5 per 100,000 children. ⋯ Crohn's disease now appears to be at least as common as ulcerative colitis. Thirty-five of 55 patients first classified as indeterminate colitis or probable Crohn's disease later fulfilled the criteria of ulcerative colitis or Crohn's disease during a mean follow-up period of 4.6 years. This study emphasizes the importance, in epidemiological studies of inflammatory bowel disease, of including those cases where a definite diagnosis of ulcerative colitis or Crohn's disease cannot be established initially and of re-evaluating the initial diagnosis regularly.

Comparative Study
Continuous non-invasive finger blood pressure monitoring in children.
We evaluated the performance of continuous non-invasive finger arterial pressure measurement using the volume-clamp technique (Finapres). This study was designed to compare finger arterial pressure with brachial blood pressure estimated by the auscultatory method in 217 children (90 boys and 127 girls) aged 4-16 years and in 38 adults (aged 18-45 years). Finger and brachial artery pressure readings were obtained consecutively from the ipsilateral side in the supine position. ⋯ There was large inter-individual variability in Finapres recordings which might be due to differences in vasomotor tone, as demonstrated by systolic amplification in 5 patients with anorexia. However, Finapres showed a small within-subject variability (3.8 mmHg for systolic and 4.1 mmHg for diastolic pressure) determined in 5 patients during phenylephrine infusion, and as good reproducibility as the auscultatory method. These results suggest that finger arterial pressure measurement in children older than 6 years of age has similar accuracy as that in adults, and that this method is useful for clinical applications in children, especially for the non-invasive evaluation of autonomic control and cardiovascular reflexes involving transient and rapid blood pressure changes.

Comparative Study
Arterial or mixed venous lactate measurement in critically ill children. Is there a difference?
Seven critically ill children had simultaneous measurement of whole blood lactate concentrations obtained from a systemic arterial and mixed venous (pulmonary artery) site. An excellent correlation was found (r = 0.995). The mean difference between arterial and mixed venous values was 0.02 mmol/l and the limits of agreement (+/- 0.22) were -0.20 to 0.24. The differences found were clinically insignificant (two-tailed paired Student's t-test; p = 0.36) and therefore support the continued use of arterial sampling for blood lactate measurement.

Comparative Study
"Minitouch" treatment of very low-birth-weight infants.
In a cohort study with historical controls of non-asphyxiated very low-birth-weight infants (birth weight < or = 1500 g and gestational age < 33 completed weeks), we evaluated the use of a "minitouch" regime for stabilization after birth and treatment of respiratory distress. This combination of early (prophylactic) treatment with nasal continuous positive airway pressure and minimal handling was introduced as a routine in our Department in 1986. We compared infants born in 1987 and in 1985, when ventilator treatment was used initially in all infants with progressing respiratory distress. ⋯ Septicaemia was diagnosed in 16% of the infants in 1987 versus 7% in 1985 (p = 0.045). This difference coincided with an increased use of total parenteral nutrition (18% in 1987 versus 3% in 1985, p = 0.007). We conclude that the minitouch regime prevents progression of respiratory distress, reduces the need for ventilator treatment and is a safe and convenient alternative to mechanical ventilation in preterm infants with mild respiratory problems.(ABSTRACT TRUNCATED AT 250 WORDS)

Multicenter Study Comparative Study
Mothers' perceptions of their preterm infants treated in an incubator or on a heated water-filled mattress: a pilot study.
Ten Swedish and 23 Turkish mothers delivering premature infants with a birth weight of less than 2000 g were investigated concerning their attitudes and feelings towards their newborn babies when the infants were treated either in an air-heated incubator or on a heated water-filled mattress (HWM). The first interview took place during the first few days after delivery and the second interview in the case of the Swedish study two weeks later and in the Turkish study one week later. ⋯ These feelings had changed strikingly by the time of the second interview among the mothers whose infants were treated on the HWM, but persisted to a large extent among the mothers whose infants remained in an incubator. The results of both investigations indicate that the mothers' perceptions of their infants improves when the prematurely born infant is treated on an HWM instead of in an incubator.
