Correlative study of iron accumulation in liver, myocardium, and pituitary assessed with MRI in young thalassemic patients.
Clinical complications resulting from unevenly iron accumulation in individual organs of patients with beta-thalassemia major can affect both expectancy and quality of life. Magnetic resonance imaging (MRI) offers a quantitative, noninvasive, accurate method for estimating iron levels in various tissues, not easily accessible with other techniques. The aim of this study was to evaluate and correlate the level of iron accumulation in different organs (anterior pituitary, myocardium, and liver) assessed with MRI, in children and young adults with beta-thalassemia major. ⋯ In conclusion, iron accumulation in thalassemic patients is a procedure progressing with age, which seems to act independently in different organs. MRI represents a reliable, noninvasive method for assessing iron overload in various tissues, non-easily accessible with other techniques. Regular scanning, to recognize preclinically excessive iron deposits and intensified chelation therapy, can prevent serious and fatal complications.

Autoimmune hypothyroidism after unrelated haematopoietic stem cell transplantation in children.
We describe two pediatric patients who developed autoimmune hypothyroidism 2 years after unrelated allogeneic hematopoietic stem cell transplantation. The causes of post-transplantation autoimmune hypothyroidism are probably multiple. In these two patients, the presence of chronic graft-versus-host disease may be the most significant contributing factor.
