Cerebral gigantism of hypothalamic origin
European Journal of Pediatrics
|April 1, 1983
Summary
Sotos Syndrome can involve elevated growth hormone and somatomedin activity, potentially contributing to gigantism. Further research is needed to understand the complex pathogenesis of this genetic disorder.
Area of Science:
- Endocrinology
- Genetics
- Pediatrics
Background:
- Sotos Syndrome is a genetic disorder characterized by overgrowth.
- The exact mechanisms causing gigantism in Sotos Syndrome are not fully understood.
Observation:
- Serum somatomedin activity was measured in five Sotos Syndrome cases.
- Elevated growth hormone secretion was noted in two patients.
- Hydrocephalus with increased intracranial pressure was observed in the index case, ruling out a hypothalamic tumor.
Findings:
- Two out of five Sotos Syndrome patients exhibited elevated somatomedin activity.
- Increased growth hormone secretion was observed in these two patients.
- The index case presented with hydrocephalus, not a hypothalamic tumor.
Implications:
- These findings suggest a potential link between growth hormone and somatomedin activity in Sotos Syndrome-related gigantism.
- Understanding these hormonal imbalances is crucial for managing Sotos Syndrome.
- Further investigation into the pathogenesis of gigantism in Sotos Syndrome is warranted.
