[Degree of prematurity in some forms of infantile cerebral palsy]
Insights
Prematurity impacts infantile cerebral palsy (ICP) forms. Seventh-month premature infants are prone to diparetic ICP, while eighth-month infants often develop extrapyramidal ICP, suggesting different etiological factors.
Area of Science:
- Neurology
- Developmental Pediatrics
Context:
- Infantile cerebral palsy (ICP) is a group of disorders affecting movement and posture.
- Prematurity is a significant risk factor for adverse neurodevelopmental outcomes.
- Understanding the relationship between gestational age, birth weight, and specific ICP subtypes is crucial for targeted interventions.
Purpose:
- To investigate the association between prematurity (gestational age and birth weight) and the specific forms of infantile cerebral palsy (diparetic and extrapyramidal).
- To explore potential etiological differences in the development of diparetic versus extrapyramidal ICP in premature infants.
Summary:
- Premature infants born in the 7th month of gestation with lower birth weights (<1700g) were more frequently diagnosed with the diparetic form of ICP.
- Premature infants born in the 8th month of gestation with higher birth weights (>2000g) showed a higher incidence of the extrapyramidal form of ICP.
- Asphyxia was identified as a frequent etiological factor for the extrapyramidal form in premature infants, potentially linking kernicterus to hypoxemia.
Impact:
- Findings suggest that the timing of prenatal insults may influence the type of ICP that develops.
- Early-term (7th month) prematurity appears to be a stronger risk factor for diparetic ICP, possibly due to earlier pathogenetic factor exposure.
- Late-preterm (8th month) infants are more susceptible to extrapyramidal ICP, with asphyxia being a key contributing factor, highlighting the role of hypoxemia.
Abstract:
The author discusses the problem of prematurity as a criterion of developmental degree in a group of children with diparetic and extrapyramidal forms of infantile cerebral palsy. In the group of diparetic form premature babies born in the 7th month of pregnancy with birth weight below 1700 g prevailed, while in the extrapyramidal form babies born in the 8th month of pregnancy with birth weight above 2000 g were most frequent. This suggests that the development of the diparetic form of infantile cerebral palsy is due to earlier action of the pathogenetic factor. Among the aetiological factors causing the extrapyramidal form in premature babies asphyxia was the most frequent one. This may indicate that changes observed in kernicterus are due primarily to hypoxaemia. In conclusion the author states that premature babies born in the 7th month of pregnancy face mainly the danger of diparesis, while in those born in the 8th month the extrapyramidal form of infantile cerebral palsy is more frequent.
