Brain tissue aspiration neural tube defect
Academia Brasileira de Neurologia - ABNEURO, 2005Co-Authors: Peres,luiz Cesar, Barbosa,gustavo Henrique T. De SalesAbstract:The study aimed to find out how frequent is brain tissue aspiration and if brain tissue heterotopia could be found in the lung of human neural tube defect cases. Histological sections of each lobe of both lungs of 22 fetuses and newborn with neural tube defect were immunostained for glial fibrillary acidic protein (GFAP). There were 15 (68.2%) females and 7 (31.8%) males. Age ranged from 18 to 40 weeks of gestation (mean= 31.8). Ten (45.5%) were stillborn, the same newborn, and 2 (9.1%) were abortuses. Diagnosis were: craniorrhachischisis (9 cases, 40.9%), anencephaly (8 cases, 36,4%), ruptured occipital encephalocele and Rachischisis (2 cases, 9.1% each), and early amniotic band disruption sequence (1 case, 4.5%). Only one case (4.5%) exhibited GFAP positive cells inside bronchioles and alveoli admixed to epithelial amniotic squames. No heterotopic tissue was observed in the lung interstitium. We concluded that aspiration of brain tissue from the amniotic fluid in neural tube defect cases may happen but it is infrequent and heterotopia was not observed

Havia 15 casos femininos (68,2%) e 7 masculinos (31,8%), com idade gestacional variando de 18 a 40 semanas (média= 31,8), sendo natimortos e neomortos 10 (45,5%) cada e 2 (9,1%) abortos. Os diagnósticos foram: Craniorraquisquise (9 casos, 40,9%), anencefalia (8 casos, 36,4%), encefalocele occipital rota e raquisquise (2 casos, 9,1%) e 1 (4,5%)caso de seqüência de disruptura amniótica precoce. Somente 1 caso (4,5%) apresentou células positivas dentro de bronquíolos e alvéolos em meio a células epiteliais amnióticas. Não se observou heterotopia no interstício pulmonar. Concluímos que a aspiração de tecido encefálico do líquido amniótico pode ocorrer em casos de defeito do fechamento do tubo neural, mas são infreqüentes e heterotopia não foi observada

BRAIN TISSUE ASPIRATION IN NEURAL TUBE DEFECT
2015Co-Authors: Luiz Cesar PeresAbstract:ABSTRACT- The study aimed to find out how frequent is brain tissue aspiration and if brain tissue hetero-topia could be found in the lung of human neural tube defect cases. Histological sections of each lobe of both lungs of 22 fetuses and newborn with neural tube defect were immunostained for glial fibrillary acidic protein (GFAP). There were 15 (68.2%) females and 7 (31.8%) males. Age ranged from 18 to 40 weeks of gestation (mean = 31.8). Ten (45.5%) were stillborn, the same newborn, and 2 (9.1%) were abor-tuses. Diagnosis were: craniorrhachischisis (9 cases, 40.9%), anencephaly (8 cases, 36,4%), ruptured occip-ital encephalocele and Rachischisis (2 cases, 9.1 % each), and early amniotic band disruption sequence (1 case, 4.5%). Only one case (4.5%) exhibited GFAP positive cells inside bronchioles and alveoli admixed to epithelial amniotic squames. No heterotopic tissue was observed in the lung interstitium. We concluded that aspiration of brain tissue from the amniotic fluid in neural tube defect cases may happen but it is infrequent and heterotopia was not observed.

anencephalic fetus with craniospinal Rachischisis case report
International Journal of Research, 2021Co-Authors: Ayse KonacAbstract:Anencephaly, in which a substantial part of the brain, skull, or scalp is missing, is a lethal neural tube defect (NTD) that occurs during the fourth week of pregnancy after failed cranial neuropore closure. One in every 1,000 births is anencephalic, and newborns with this NTD are not viable or treatable. Associated with anencephaly is Rachischisis, or severe incomplete neural tube closure and exposure of the spinal cord. Ultrasonography can quickly diagnose anencephaly. Like other NTDs, nutritional and environmental factors both play a role in the development of anencephaly. Here, we report and discuss an unusual case of a 12-week gestation anencephalic fetus with craniospinal Rachischisis and its embryological roots. In our case, except from the low socio-economic life of the patient, the absence of a predisposing factor that could cause such an anomaly, the abortion being in the first trimester and the occurrence in the first pregnancy of the patient as a result of 5-year infertility made us think that pathology examination of the abortus material is important in complet or incomplete abortions.
