Table 1.
Perinatal characteristics of the fullterm and preterm group.
| Fullterms (n = 17) | Preterms (n = 10) | |
|---|---|---|
| Gender (boys/girls) | 6/11 | 6/4 |
| Gestational age (weeks) | 40.3 (37.0–42.0) | 29.2 (27.3– 32.0) |
| Birth weight (g) | 3550 (2880–4100) | 1130 (640– 2035) |
| IUGR (<10th percentile) | 0 (0%) | 1 (10%) |
| Apgar score at 5 min | 8 (1– 9) | |
| Asphyxia | 5 (50%) | |
| Late-onset sepsis (positive blood culture) | 1 (10%) | |
| Retinopathy of prematuritya | 0 (0%) | |
| BPD (O2 at 36 weeks’ PMA) | 4 (40%) | |
| Mechanical ventilation (days) | 4 (1– 13) | |
| Cerebral pathology | ||
| None | 3 (30%) | |
| PVE > 7 days | 3 (30%) | |
| Mildb | 4 (40%) | |
| Severec | 0 (0%) |
Data are given as median (minimum–maximum) or numbers (percentage). IUGR, intra-uterine growth restriction; BPD, bronchopulmonary dysplasia; PMA, postmenstrual age; PVE, periventricular echodensities. Cranial ultrasound results were graded according to Papile et al. (41) and de Vries et al. (42). Empty boxes indicate that data were not available or did not apply.
aRetinopathy of prematurity Stage II or worse.
bMild cerebral pathology was defined as Grades I and II germinal matrix–intraventricular hemorrhage (GMH–IVH).
cSevere cerebral pathology was defined as Grade III GMH-IVH, periventricular hemorrhagic infarction, posthemorrhagic ventricular dilatation (PHVD), and cystic periventricular leukomalacia. PHVD was defined as a lateral ventricle size of >0.33 according to Evans’ index.
