Article Abstract

Aim: This study aims to assess the incidence of retethering in patients who underwent surgery for tethered cord in our clinic.

Material And Methods: We included patients who underwent surgical intervention for tethered cord in our clinic between 2010 and 2020 and were subsequently diagnosed with retethering during follow-up. Only those with available postoperative clinical follow-up data were included. The study analyzed the timing of surgery, gender, presenting symptoms, intraoperative findings, postoperative outcomes-including complications-and follow-up duration.

Results: Over a 10-year period, 59 patients underwent surgery for tethered cord. Among them, 11 patients required reoperation for retethering at a median age of 5 years. The median interval between the initial and retethering surgeries was 47.6±43.20 months. Two patients were asymptomatic at the time of their initial surgery. Among the 11 patients with retethering, 3 (27.2%) presented with bladder or bowel dysfunction, 4 (36.3%) with neuro-orthopedic symptoms, and 4 (36,3%) with pain. Two patients experienced a second episode of retethering and required a third surgery, which occurred approximately 2 years after the second procedure.

Conclusion: The risk of retethering should be carefully monitored in patients with tethered cord, particularly during growth periods.

Background: Closure of soft tissue defects following surgical repair of neonatal myelomeningocele requires prompt and well-justified decisions regarding the reconstruction method if the defects are to be closed within the first two days of life. For larger defects, flap reconstruction is often necessary. The aim of the study was to examine reconstruction methods for closing soft tissue defects following surgery for myelomeningocele, as well as complications and the need for reoperation.

Loss of actin cytoskeleton control can hinder integral developmental and physiological processes and can be the basis for a subset of developmental defects. SHROOM3 is an actin binding protein, best characterized as being essential for neural tube closure in vertebrates. Shroom3 expression has also been identified in the developing heart, with some associated congenital heart defects.

Autism spectrum disorder (ASD) is a developmental disability characterized by impaired social communication and repetitive behaviors, and environmental and genetic factors are involved in its onset. The use of the antiepileptic drug valproic acid (VPA) during pregnancy is associated with neural tube defects and developmental disorders in the fetus. In this study, we aimed to identify abnormalities in cortical morphogenesis owing to prenatal VPA exposure and to elucidate the abnormalities in brain function associated with these abnormalities, particularly by comparing multiple and single environments.
