ABSTRACT
Objective: The study was undertaken to determine the proportion and pattern of Neural Tube Defects (NTD)reported at tertiary care teaching hospital in Gurugram. The incidence of NTDs were determined and comparedwith other studies done in India and other countries.Material and methods: The study was carried out in SGT Medical College Hospital and Research Institute,Gurugram. The total number of deliveries was recorded from 2017- 2019.The aborted fetuses with NTDs wereobserved in detail externally for the sex, type of NTD and other associated anomalies after obtaining ethicalclearance and written informed consent of the parents.Results: The number of deliveries conducted between 2017-2019 at SGT Medical College Hospital and ResearchInstitute, Gurugram was 2500. There were 8 babies born with NTDs (5 female and 4 male). Overall incidence ofNTDs in the present study was 3.2/1000 births with female preponderance. The incidence of fetuses withanencephaly, myelocele, meningomyelocele, craniorachischisis and encephalocele were 0.8, 1.2, 0.4, 0.4, and0.4 per 1000 births respectively.Conclusion: Birth defects like Neural Tube Defects are easily detected by routine screening tests like USG in firstand second trimester of pregnancy. Public health measures like preconception folic acid supplements andincreasing awareness about maternal care during pregnancy needs to be highlighted to decrease the incidenceof congenital anomalies and their comorbidities.
ABSTRACT
Neural tube defects [NTDs] are the disorders caused due to non closure of neural tube during 3rd to 4th week of embryonic period. NTDs have an incidence of 1-2 per 1000 births. Major types of NTDs include anencephaly, spinabifida, craniorachischisis, encephalocele, inencephaly. Present study was carried out to study craniorachischisis and associated malformations. Method: study was carried out on 24 weeks aborted female fetus showing gross neural tube defect, in department of anatomy. Result: fetus was having craniorachischisis i.e. complete failure of neurulation along with facial dismorphism and other malformations.
ABSTRACT
Neural tube defect spectrum (NTD) includes anencephaly, spina bifida, craniorachischisis, inencephaly etc. Four cases of craniorachischisis were studied from a collection of 34 aborted fetuses. There was deficiency of scalp and cranial vault in all the four cases. In one case the defect was extending up to the cervical region, in rest of the three cases, vertebral column defect extended upto thoracic region exposing the spinal cord and spinal nerves. All the cases presented with bulging eyes, broad nose, folded ears, protruded tongue and absent neck. These defects result due to failure of closure of the neural tube during early embryonic life.
ABSTRACT
Congenital malformations with multiple anomalies have been described infrequently in the veterinary literature. A stillborn male crossbred lamb with diprosopus, craniorachischisis, and arthrogryposis was examined macroscopically and histopathologically in this study. The left head was smaller than the right head. Micrencephaly, agnathia, and a rudimentary tongue, which was adherent to the palate, were present in the left head. Micrencephaly, brachygnathia superior, and cleft palate were present in the right head. Cerebellar agenesis and spinal cord hypoplasia were observed. The cerebrums and the spinal cord were covered with a tapering membranous structure. Neural and dermal tissues were noted to intervene upon microscopic examination of this structure. Disorganization of neurons was observed in both cerebrums, though it was more severe in the left one. This case demonstrates many congenital defects occurring together in a lamb.
