Vitamin B12 treatment reduces mononuclear DNA damage.

Background: DNA damage effects of vitamin B(12) deficiency were performed in vitro and in adults.

Methods: The study group included 32 children (13 girls, 19 boys) with vitamin B(12) deficiency (mean age 44 ± 58 months) and their 27 mothers (mean age 30.4 ± 5.

Phototherapy increases DNA damage in lymphocytes of hyperbilirubinemic neonates.

Phototherapy is commonly used in the treatment of hyperbilirubinemia in newborns. No serious side effects related to phototherapy have been observed, but concerns regarding its potential to damage DNA have been expressed, based on animal or cell-culture studies. The aim of this study was to investigate, in neonates with hyperbilirubinemia, the possible relation between phototherapy and DNA damage.
