Clinico-epidemiological profile and outcomes of babies with neural tube defects in a tertiary care center in Northern India.

Introduction: Neural tube defects constitute a major source of disability among children. Proper management requires accurate diagnosis, an assessment of the severity of the lesion, a decision whether intervention is warranted, the nature of the intervention, and educating the family of the need for lifelong medical care. But to do so, reliable data regarding presentation and outcome is very crucial.

Aim Of The Study: To discuss the clinical epidemiological profile and outcome of babies admitted with neural tube defects (NTDs).

Material And Methods: Retrospective observational study was done by extracting data from case notes and follow-up files in Department of Neonatology, PGIMER and Dr. RML Hospital, New Delhi over a period from March 2015 to July 2020.

Results: A total of 25 babies were included in the study. Majority of babies were born to mother at a median age group of 24 (19-36) yrs and nearly one-third of them were illiterate. The history of maternal periconceptional folic acid intake was seen in only five babies (21%). Two third of babies were male (64%) and the median age at admission was at 9 (1-27) days of life. Majority of the cases were open types of NTDs with most common type being meningomyelocele (88%) followed by occipital encephalocele (12%) and there was one case of closed type of neural tube defect having lipomeningomyelocele (4%). The most common associated anomaly was hydrocephalus (76%) followed by Arnold chiari malformation (56%). Motor weakness in form of paraparesis or paraplegia was present in 21 (84%) babies and sensory deficit was present in 44% babies. Bowel and bladder dysfuntion was present in 48% of cases. Ventriculitis was the most common associated morbidity (38%). Meningomyelocele (MMC) repair was the most commonly performed primary surgery (33%) followed by Ventriculo-peritoneal (VP) shunt repair (24%). Twelve babies (48%) were discharged while 2 (8%) expired and 11 (44%) babies left against medical advice.

Conclusion: Neural tube defect is a congenital disorder with significant morbidity. The clinical severity of the NTDs and the uncertainty in their cause makes this a priority for further research. National policies for prevention, in utero diagnosis, and early surgical intervention are required for a better prognosis.
