Alterations of bone mineral metabolism of children with different cell lineage types of acute lymphoblastic leukaemia under chemotherapy.

Background: Children with haematological malignancies such as acute lymphoblastic leukaemia (ALL) may have alteration of bone mineral metabolism therefore increased risk for osteopenia and osteoporosis.

Patients And Methods: The purpose of this study was to examine the alterations of bone mineral metabolism in two groups of children (n=42) according to immunophenotyping (B-cell type, T-cell type) both quantitative (bone mineral density z-scores) and qualitative (serum osteocalcin - OC and carboxyl-terminal telopeptide of human type I collagen - ICTP) during diagnosis (T=0), after the intensified chemotherapy period (T=0.5) and the consolidation period (T=1).

Evaluation of popliteal arteries with CT angiography in popliteal artery entrapment syndrome.

Background: Popliteal artery entrapment is an uncommon clinical entity that occurs due to compression of the popliteal artery by adjacent muscle and tendinous structures. Early diagnosis should be established through a combined approach of careful physical examination and history-taking, duplex ultrasonography, and CT angiography.

Patients And Methods: We have studied retrospectively 16 patients of popliteal artery entrapment syndrome, 9 men and 7 women.
