The incidence of inguinal hernia among 247 children with cerebral palsy was ascertained. During the first year of life, 20 of the 153 boys developed hernia, as did one of the 94 girls. Among boys with birthweights of 1000 to 2000g the incidence was 31 per cent, which is twice the rate for normal children. The incidence among boys with birthweights greater than 2000g was 8 per cent. A comparison group could not be found, but this incidence appears to be excessive, considering the reported normal incidence of 1 to 4 per cent in boys. The authors recommend routine examination for inguinal hernia, particularly for boys with birthweights less than 2000g and with spastic tetraplegia. Conversely, one should be alert to the possibility of concurrent spasticity in preterm males with inguinal hernia.

Of 99 children in the Royal Blind School, Edinburgh (which serves Scotland and part of N E England), 15 had optic atrophy (hydrocephalus 4, intracranial haemorrhage 2, prematurity 2, fetal distress 2, birth asphyxia 2, cerebral atrophy 1, cardiac arrest during hernia operation 1, and leukaemia 1). Fourteen had congenital cataract, 12 congenital retinal aplasia (Leber's congenital amaurosis) and 11 retinopathy of prematurity. There were small numbers in many other diagnostic categories, including three with non-accidental head injury. Mental retardation, spasticity, and nystagmus were frequent other correlates in all diagnostic categories. 'Very probably hereditary' was a conservative attribution in 36, while 'probable' seemed appropriate for 12-that is, almost 48% were hereditary. Only about 11 cases might have been prevented through genetic counselling, which testifies to the frequency of autosomal recessive hereditary disease, although no parents were consanguineous.

Two cases of anterior spinal hernia are presented. The medical literature is reviewed, the syndrome characterised, and its cause and treatment discussed. The patient is typically middle aged with a history of stepwise slowly progressive mid-thoracic anterior hemicord syndrome manifesting as hemianalgesia below the affected segment, followed by contralateral lower limb spasticity that develops into an asymmetric paraparesis with sparing of dorsal column sensation. Radiological investigation demonstrates an enlarged dorsal arachnoid space in association with an apparently focally narrowed thoracic cord, kinked towards the anterior dura. At operation the cord is found to be prolapsed into an anterolateral dural diverticulum. The most likely cause of this syndrome is anterior spinal artery segmental branch ischaemia, in a cord chronically incarcerated in a congenital anterior meningocele. This readily treatable condition should be considered in all cases of thoracic cord dysfunction and surgical repair effected early to prevent stepwise progression to paraplegia.

Retinoic acid (RA) signaling plays a key role in the development and function of several systems in mammals. We previously discovered that the de novo mutations c.1159C>T (p.Arg387Cys) and c.1159C>A (p.Arg387Ser) in the RA Receptor Beta (RARB) gene cause microphthalmia and diaphragmatic hernia. However, the natural history of affected subjects beyond the prenatal or neonatal period was unknown. Here, we describe nine additional subjects with microphthalmia who have de novo mutations in RARB, including the previously described p.Arg387Cys as well as the novel c.887G>C (p.Gly296Ala) and c.638T>C (p.Leu213Pro). Moreover, we review the information on four previously reported cases. All subjects who survived the neonatal period (n = 10) displayed severe global developmental delay with progressive motor impairment due to spasticity and/or dystonia (with or without chorea). The majority of subjects also showed Chiari type I malformation and severe feeding difficulties. We previously found that p.Arg387Cys and p.Arg387Ser induce a gain-of-function. We show here that the p.Gly296Ala and p.Leu213Pro RARB mutations further promote the RA ligand-induced transcriptional activity by twofold to threefold over the wild-type receptor, also indicating a gain-of-function mechanism. These observations suggest that precise regulation of RA signaling is required for brain development and/or function in humans.
