Serum iron, ferritin, transferrin, total iron binding capacity, hs-CRP, LDL cholesterol and magnesium in children; new reference intervals using the Dade Dimension Clinical Chemistry System.

BACKGROUND: We studied serum/Plasma iron, ferritin, transferrin concentrations, and total iron binding capacity (TIBC) in addition to highly sensitive C-reactive protein (hs-CRP), low-density lipoprotein (LDL) cholesterol and magnesium concentrations in a population of 800 in- and outpatients and defined new 95% reference intervals for pediatrics using the Dade Behring RxL Dimension Clinical Chemistry System. METHODS: Plasma/serum concentrations of the above analytes were determined on patient samples accrued from January to June 2003 and the data were analyzed employing a computer adapted Hoffmann approach. RESULTS AND CONCLUSIONS: New pediatric reference intervals on the Dade RxL Dimension were obtained for serum iron, ferritin, transferrin, TIBC, hs-CRP, LDL-cholesterol and magnesium. This work represents the first hs-CRP data for children <3 years old. The values for all the analytes were established on new data (n=800). These values are new for hs-CRP and LDL cholesterol, while for iron, ferritin and magnesium these intervals are more reliable than those previously published by our group which had used regression equations on samples measured by the old (Vitros/Immuno1) methods for which intervals were available.

Selective nerve root blocks.

Selective nerve root blocks are valuable diagnostic and therapeutic procedures in patients with radicular symptoms. Understanding the anatomy, benefits, and risks, as well as precise needle placement, are important factors in performing successful nerve root blocks. The techniques we describe come from our training and ongoing experience. There are other acceptable methods as well.

Epidural steroid injections.

Epidural steroid injections have a significant role in the treatment of patients with low back, neck, and radicular pain. Although these procedures may not address the causative lesions, they often shorten the clinical course of the disease process, keep patients out of the hospital, and provide symptomatic relief that improves quality of life. These procedures are most accurately performed with fluoroscopic guidance and major complications are rare. Although support for cervical epidural steroid injection is less uniform than that for lumbar and caudal injections, a growing body of experience is beginning to support its efficacy and safety.
