Isthmic Spondylolisthesis in Young Gymnasts: A Report of Two Cases.

Isthmic spondylolisthesis is a condition characterized by the subluxation of one vertebral body over the adjacent inferior vertebral body, secondary to a defect in the pars interarticularis. This paper reports two cases of young acrobatic gymnasts who presented with long-term, progressive lumbosciatic pain and lower limb dysesthesia. One gymnast presented with additional neurogenic bladder dysfunction.

[Devic's disease].

Devic's disease, also known as Neuromyelitis Optica, is a demyelinating disease of the central nervous system, with selective involvement of the spinal cord and optic nerves. The authors describe a clinical case of acute myelitis, initially approached in the context of a nonspecific syndrome gripal, with subsequently sudden bilateral amaurosis, which leads to the diagnosis hypotesis of Devic's disease, a disease with poor prognosis in optic-spinal function and adequate symptomatic treatment.
