Vitamin C in disease prevention and cure: an overview

The recognition of vitamin C is associated with a history of an unrelenting search for the cause of the ancient haemorrhagic disease scurvy. Isolated in 1928, vitamin C is essential for the development and maintenance of connective tissues. It plays an important role in bone formation, wound healing and the maintenance of healthy gums. Vitamin C plays an important role in a number of metabolic functions including the activation of the B vitamin, folic acid, the conversion of cholesterol to bile acids and the conversion of the amino acid, tryptophan, to the neurotransmitter, serotonin. It is an antioxidant that protects body from free radical damage. It is used as therapeutic agent in many diseases and disorders. Vitamin C protects the immune system, reduces the severity of allergic reactions and helps to fight off infections. However the significance and beneficial effect of vitamin C in respect to human disease such as cancer, atherosclerosis, diabetes, neurodegenerative disease and metal toxicity however remains equivocal. Thus further continuous uninterrupted efforts may open new vistas to understand its significance in disease management.

Challenges in pediatric peritoneal dialysis in Turkey

Chronic peritoneal dialysis (CPD) is the modality of choice for children with end-stage renal disease in Turkey. CPD was first instituted in 1989 in Turkish pediatric patients by using imported basic equipment and solutions since then the number of patients on CPD increased gradually. Parallel to the developments in the PD industry, in 2002, the Turkish Pediatric Nephrology Association established the Turkish Pediatric Peritoneal Dialysis (TUPEPD) Study Group to study peritoneal dialysis in children and adolescents. Today in Turkey, almost all of the PD equipment and PD solutions are available. Turkish pediatric nephrologists now have a significant experience with PD. Physicians, parents, and the children prefer to start with CPD because of its advantages, such as a more liberal social life and better school attendance.
