Because lead and calcium are used interchangeably by bone, lead deposition occurs in high concentrations in growing bones; the greatest concentration occurs in the metaphyses, particularly those in the distal femora, ends of the tibiae, and distal radii, because these are the parts of the skeleton that grow most rapidly. Hollerman JJ. 8. Dense metaphyseal bands (Concept Id: C4020919) - National Center for Pediatr Radiol. Tutar and associates described a case of a 12-year-old girl who presented with recurrent pericardial effusion caused by a firearm pellet injury to the left ventricle. Pediatric Radiology These findings suggest that an increase in lead burden leads to an increase in the release of CPK-MB from the myocardial cells and that slight myocardial damage occurs, which might conceivably impair diastolic cardiac function.

EXPLANATION

Normal metaphyseal endochondral bone growth (in the zone of provisional calcification) requires the maintenance of a delicate balance between osteoblastic bone deposition and osteoclastic bone remodeling (. In our group we saw thin sclerotic metaphyseal bands and overall increased . 1991;91:17-32. This may sometimes be pronounced and may lead to a false-positive diagnosis of lead intoxication. These abnormalities suggest that the underlying defect in type V OI may involve a molecule common to both bone and cartilage that is involved in the regulation of growth plate development and metadiaphyseal . Distal femoral epiphyses appeared centrally . A finding of disruption of brain plasticity, as seen on MRIs, is not a finding unique to lead intoxication. 1980 Jul. 2018 Jun 1.
