Workup

  • It is suggested that a complete perinatal workup including necropsy can lead to a precise diagnosis in most cases.[file.scirp.org]

Gliosis
  • Lesions arising later in the third trimestr and perinatal period heal with gliosis but without abnormal gyral pattern.[atlases.muni.cz]

Treatment

  • Food and Drug Administration has chosen Wave Life Sciences’ planned phase 2/3 study of suvodirsen, its lead experimental therapy for the treatment of Duchenne muscular dystrophy, to break new ground.[globalgenes.org]
  • Given the rarity of these diseases, the treatments outlined in the abstracts are not always evidence based. The information in the abstracts isnot intended to replace existing local, regional or country specific recommendations and guidelines.[orpha.net]
  • It is not in any way intended to be used as a substitute for professional medical advice, diagnosis, treatment or care.[uniprot.org]
  • Treatment of manifestations: Management focuses on the parents' wishes for provision of comfort-care for the newborn. Newborns require respiratory support (with tracheostomy and ventilation) to survive.[ncbi.nlm.nih.gov]
  • An accurate and early syndromic diagnosis of congenital malformations is of vital importance, as late diagnosis can result in a delay in intervention and treatment of accompanying anomalies such as congenital heart defects or endocrine disorders.[centogene.com]

Prevention

  • Plays a central role in germ cell development: acts by degrading RA in the developing testis, preventing STRA8 expression, thereby leading to delay of meiosis.[uniprot.org]
  • After birth of one child with NTD a couple should be counseled about prevention in subsequent pregnancies; primary prevention by periconceptional folic acid supplementation and secondary prevention by antenatal ma- ternal serum alpha feto protein (MSAFP[file.scirp.org]
  • All affected infants with short-rib polydactyly syndrome have severe pulmonary hypoplasia that prevents extrauterine survival. Chromosomes are usually normal. Genes responsible for these conditions have not yet been identified.[mhmedical.com]
