ABSTRACT
OBJECTIVE: After lowering the Dutch threshold for active treatment from 25 to 24 completed weeks' gestation, survival to discharge increased by 10% in extremely preterm live born infants. Now that this guideline has been implemented, an accurate description of neurodevelopmental outcome at school age is needed. DESIGN: Population-based cohort study. SETTING: All neonatal intensive care units in the Netherlands. PATIENTS: All infants born between 240/7 and 266/7 weeks' gestation who were 5.5 years' corrected age (CA) in 2018-2020 were included. MAIN OUTCOME MEASURES: Main outcome measure was neurodevelopmental outcome at 5.5 years. Neurodevelopmental outcome was a composite outcome defined as none, mild or moderate-to-severe impairment (further defined as neurodevelopmental impairment (NDI)), using corrected cognitive score (Wechsler Preschool and Primary Scale of Intelligence Scale-III-NL), neurological examination and neurosensory function. Additionally, motor score (Movement Assessment Battery for Children-2-NL) was assessed. All assessments were done as part of the nationwide, standardised follow-up programme. RESULTS: In the 3-year period, a total of 632 infants survived to 5.5 years' CA. Data were available for 484 infants (77%). At 5.5 years' CA, most cognitive and motor (sub)scales were significantly lower compared with the normative mean. Overall, 46% had no impairment, 36% had mild impairment and 18% had NDI. NDI-free survival was 30%, 49% and 67% in live born children at 24, 25 and 26 weeks' gestation, respectively (p<0.001). CONCLUSIONS: After lowering the threshold for supporting active treatment from 25 to 24 completed weeks' gestation, a considerable proportion of the surviving extremely preterm children did not have any impairment at 5.5 years' CA.
ABSTRACT
OBJECTIVE: Since 2010 the guideline 'Guideline for perinatal policy in cases of extreme prematurity' has advised an active policy in infants born at 24 weeks gestation. We investigated how infants born at 24 and 25 weeks gestation in the first year following the implementation of the guideline had developed by the age of 2 years. DESIGN: Retrospective national cohort study. METHOD: The study population consisted of all surviving infants born in the Netherlands at 24 or 25 weeks gestation in the period from 1 October 2010 to 1 October 2011. At a corrected age of 2 years the children underwent a general physical and neurological examination, and their cognitive scores were determined on the 'Bayley scales of infant and toddler development' (Bayley III). Examinations took place in the 10 neonatal intensive care units (NICU's) in the Netherlands. RESULTS: Of 185 extremely premature infants, 166 were admitted to a NICU. A total of 95 survived to a corrected age of 2 years; 78 (82%) children were examined. Their average cognitive score on the Bayley III scale was 88 (SD: 16). Among the children born at 24 weeks gestation, 20% had mild disabilities and 20% had moderate to severe disabilities. Among the children born at 25 weeks gestation, 17% had mild disabilities and 12% had moderate to severe disabilities. CONCLUSION: Of the children born at 24 weeks gestation in the first year after the introduction of active policy in the Netherlands and surviving to 2 years of age (46%), more than half had developed without disabilities. This was comparable to children born at 25 weeks gestation. Of all children born at 24 weeks gestation, 25% survived to 2 years of age without disabilities.

A 3.5-year-old boy presented with purpura on the buttocks extending towards both legs. Two weeks earlier, he had had chickenpox. Because of the rapidly progressing purpura with clinical signs of hypovolaemic shock, he was treated with fresh frozen plasma, packed red blood cells, intravenous immunoglobulins, prednisolone, acyclovir and ceftriaxone. The purpura stopped spreading. In the next few days, the skin at the site of the purpura became necrotic and was excised, as was the subcutis and part of the fascia on both legs and flanks. The right lower leg was amputated and a temporary colostomy was created to prevent faecal contamination of the wounds. The patient recovered and was discharged after three months. Purpura fulminans is a rare complication after a primary infection with varicella zoster virus. A varicella infection may lead to protein S deficiency resulting in diffuse intravascular coagulation and severe skin defects.

A girl and a boy, who both presented with recurrent respiratory infections from birth, were referred to a paediatrician at the age of 2.5 years: they were diagnosed with cystic fibrosis (CF). The girl died from respiratory insufficiency at the age of 6 years and the boy at the age of 13 years from pulmonary aspiration. A further girl and boy who presented with abnormal faeces and failure to thrive were referred to the paediatrician at the ages of 2.5 months with haematomas and 2 weeks with anaemia respectively, as a result of vitamin deficiencies due to malabsorption. They too had CF. The girl had a brain haemorrhage in the meantime that left her with serious impairments. The boy recovered. A delay in diagnosing CF is not uncommon, as the symptoms of CF are hard to differentiate from those of common childhood diseases. However, this diagnostic delay can result in serious organ damage. Current treatment of CF has a predominantly prophylactic character and aims at maintaining normal growth and nutritional status as well as at preventing or postponing chronic bacterial infection of the lower respiratory tract. This treatment is most effective when it is started before any organ damage has occurred: a state that can only be achieved when patients with CF are identified shortly after birth. Therefore, it is important to add CF-screening to the neonatal screening program.
