We review the literature and discuss the possible mechanisms.
Environmental factors may play a role during childhood, with several studies finding that people who move to a different region of the world before the age of 15 acquire the new region's risk to MS.
Syringomyelia (SM) is a painful neurological condition, prevalent in brachycephalic toy breeds including the Cavalier King Charles Spaniel (CKCS).
Elucidating the pathophysiology of syringomyelia teenage dating dress up games
Chiari III malformation consisted of a rare deformity in which the cerebellum herniated through a defect in the suboccipital bone or upper cervical lamina and created an occipitocervical encephalocele.
Beaking of the tectum, elongation and kinking of the brain stem, hydrocephalus, and lumbar spina bifida were also present.
The unsteady gait recovered completely and scoliosis improved.
Magnetic resonance imaging demonstrated resolution of the syrinx and tonsillar herniation.
Magnetic resonance imaging revealed new hindbrain tonsillar herniation and an extensive syrinx from C3 to L1.
The malfunctioning LP shunt was removed and posterior fossa decompression with ventriculoperitoneal shunt insertion was performed.The study identified a greater amount of cranium distributed caudally (relative to the amount distributed rostrally) to be significantly protective against syrinx development at the levels of three years of age, five years of age and when comparing a sample of SM clear individuals over the age of five to those affected younger than three years of age.A decreased cephalic index (decreasing brachycephaly) was significantly protective at the latter level.Unsteady gait was noted in a 2-year-old boy with a lumboperitoneal (LP) shunt that had been inserted 1 year earlier for increased head circumference caused by communicating hydrocephalus.Scoliosis was also noted during postoperative follow-up.The relevant literature on the subject has been reviewed and the author's theory has been discussed.
