Anterior Spinal Cord Fissuring: A Predictor of Spontaneous Resolution of Syrinx?
Kartik Manoj Multani,Boyina Jagadeshwar Rajesh,Krishna Kumar,Anjani Kumar 대한척추신경외과학회 2021 Neurospine Vol.18 No.1
Syringomyelia is a disorder of the spinal cord usually seen in association with a variety of craniovertebral junction anomalies (e.g., Chiari malformations, basilar invagination/impression, atlantoaxial instability, etc.). Its natural history is not very clearly understood and a majority of patients present with a slowly progressive neurological deficit followed by sudden rapid deterioration. At present, there is a general consensus to offer surgical decompression in all patients diagnosed with Chiari I malformation with syrinx irrespective of their symptoms in order to prevent delayed neurological worsening. Few authors have reported spontaneous resolution of syrinx with persistent tonsillar herniation without operative treatment. We report one such patient and propose anterior spinal cord fissuring as a plausible cause of spontaneous syrinx drainage. We also propose conservative management for patients with an anterior spinal cord fissure seen in index scans instead of early decompression of Chiari malformation.

It has been known that the sex of chicken cells can be most accurately identified by fluorescence in situ hybridization (FISH). However, the presently available FISH has not been widely used for sex identification, because the procedures for cell preparation and FISH itself are complicated and time-consuming. The present study was undertaken to test a rapid FISH procedure for sexing chicken. A FISH probe was simultaneously synthesized and labeled with digoxigenin by polymerase chain reaction (PCR) targeting a 416 bp segment of the 717 bp XhoI family fragment which is repeated over 10 thousand times exclusively in the W chromosome. Sexing by FISH was performed on cytological preparations of early embryos, adult lymphocytes and feather pulps of newly hatched chicks. The DNA probe hybridized to all types of uncultured interphase as well as metaphase female but not male cells that had been examined. Moreover, consistent with the known site of the XhoI family, the hybridization signal was localized to the pericentromeric region of the W chromosome. We, therefore, conclude that the present PCR-based FISH can be used as a rapid and reliable sex identification procedure for chicken.
