Echinococcus Granulosus in Childhood: A Retrospective Study of 187 Cases and Newer Data.

Echinococcus granulosus, first reported by Goeze in 1782, is the causative parasite of cystic echinococcosis (hydatidosis) especially for countries that are endemic areas.

Higher levels of melatonin in early stages of adolescent idiopathic scoliosis: toward a new scenario.

However, the actual role of melatonin remains unclear. The aim of this study was to assess the potential clinical value of melatonin serum level in the pathogenesis and the prognosis of AIS progression in patients who were treated nonoperatively.
