Abstract
Meningomyelocele is one of the most severe forms of neural tube defects (NTDs) and the most frequent structural birth defect of the central nervous system. We assembled the Spina Bifida Sequencing Consortium to identify causes. Exome and genome sequencing of 715 parent-offspring trios identified six patients with chromosomal 22q11.2 deletions, suggesting a 23-fold increased risk compared with the general population. Furthermore, analysis of a separate 22q11.2 deletion cohort suggested a 12- to 15-fold increased NTD risk of meningomyelocele. The loss of Crkl, one of several neural tube-expressed genes within the minimal deletion interval, was sufficient to replicate NTDs in mice, where both penetrance and expressivity were exacerbated by maternal folate deficiency. Thus, the common 22q11.2 deletion confers substantial meningomyelocele risk, which is partially alleviated by folate supplementation.

Abstract
OBJECTIVE Trauma is a leading causes of death and disability in all ages. The aim of this study was to describe the demography and characteristics of paediatric head trauma in our institution and examine the predictors of outcome and incidence of injury related mortality. METHODS We examined our institutional Trauma Registry over a 2 year period. RESULTS A total of 1100 trauma patients were seen over the study period. Of the 579 patients who had head injury 99 were in the paediatric age group. Of the paediatric head trauma patients 79 had documented Glasgow coma score (GCS), 38 (48.1%), 17 (21.5%) and 24 (30.4%) had mild, moderate and severe head injury respectively. The percentage mortality of head injury in the paediatric age group was 6.06% (6/99). There is an association between mortality and GCS (p=0.008), necessity for intensive care unit (ICU) admission (p=0.0001), associated burns (p=0.0001) and complications such as aspiration pneumonia (p=0.0001). The significant predictors of outcome are aspiration (p=0.004), the need for ICU admission (p=0.0001) and associated burns (p=0.005) using logistic binary regression. During the study period 46 children underwent surgical intervention with extradural haematoma 16 (34.8%), depressed skull fracture 14 (30.4%) and chronic subdural haematoma five (10.9%) being the commonest indication for surgeries. CONCLUSION Paediatric head injury accounted for 9.0% (99/1100) of all trauma admissions. Majority of patients had mild or moderate injuries. Burns, aspiration pneumonitis and the need for ICU admission were important predictors of outcome in children with traumatic brain injury.

Abstract
OBJECTIVE Encephalocele is a common congenital malformation of the central nervous system; however, giant encephaloceles are rare. The use of folic acid supplementation and termination of pregnancies, which are prenatally diagnosed with encephaloceles and other congenital malformation of the central nervous system, has significantly reduced the occurrence of this type of congenital malformation, especially in developed countries. METHODS This was a retrospective review over a 5-year period from January 2006 to December 2010 at the Department of Neurosurgery, Regional Centre for Neurosurgery, Usmanu Danfodiyo University Teaching Hospital, Sokoto, Nigeria. The records of patients with giant encephalocele were retrieved from the case notes of patients who had excision and repair for encephalocele. RESULTS Seventy-three patients had excision and repair of encephalocele over the study period. However, the records of only 50 patients were retrieved. Fourteen (28%) of the 50 whose records were retrieved had giant encephalocele. There were 4 male and 10 female patients (1:2.5). Thirteen (92.9%) had the lesion located in the occipital region, whereas in 1 patient (7.1%) the lesion was at the vertex. Three (21%) of the cases had microcephaly, 1 (7.1%) had macrocephaly, and 1 (7.1%) developed postoperative hydrocephalus. The average size of defect was 2.43 cm, and the size of the lesion ranged from 12 × 6 cm to 40 × 50 cm. The average maternal age was 20.3 years (n = 6), and the paternal age was 29 years (n = 4). Four out of 7 (57%) mothers had febrile illness in early pregnancy. Seven out of 10 patients (70%) did not have antenatal care. CONCLUSIONS This condition is more common in children conceived during the period when farm products are yet to be harvested, and whose mothers did not attend antenatal care visits. It is recommended that mothers should be educated on the necessity of preconception folic acid. Implementation of a national strategy on food fortification is also advised. We recommend surgery after the first month of life to reduce poor early postoperative outcomes. In developing countries and centers with suboptimal pediatric intensive care units, surgical intervention is preferred after the first month of life with good temperature control, adequate fluid replacement following rupture of the sac, blood transfusion availability, and, only if necessary, complex cranial reconstruction.
