    Abstract Background: Samples with limited volume is a common problem in laboratories receiving samples from pediatric patients. Also, pediatric samples may contain nucleated red blood cells (NRBC) which distorts the white blood cell (WBC) count and which can only be measured by some automated cell counting systems. Differential counts are sometimes required, posing the question of validity of flagging depending on age of the patients and on predilutions.
    Methods: We evaluated the hematology analyzers XE-2100 and XS-800 for their suitability in measuring hematological parameters in such samples.
    Results: With the exception of the MCHC and partly the MCH, we observed very good agreement between complete blood counts (CBC) in diluted and undiluted samples. Dilution did not impair sensitivity in the clinically relevant range nor, accuracy of the NRBC count on XE-2100. Flagging was ineffective in undiluted samples from children<1 year of age and in all diluted samples when measuring differential counts.
    Conclusions: In summary, while automated measurement of CBC and NRBC is possible in diluted samples, measurement of differential counts is restricted by loss of flagging efficiency. In addition, flagging is also ineffective in children<1 year of age using the analyzers evaluated and should, for diagnostic purposes, be performed manually.

    Abstract Background: Detection of plasma cell dyscrasias (PCD) requires screening of serum and urine for monoclonal proteins. Several studies have demonstrated increased sensitivity and specificity when measurement of serum free light chain (SFLC) is part of the screening protocol. In addition, omission of immunofixation (IFE) in the standard work-up that includes SFLC assay has been proposed. This study attempts to define the role of the SFLC assay in a screening strategy limited to serum only. It compares outcomes to a serum-only screening strategy that omits serum IFE.
    Methods: Serum from 691 patients was analysed for the presence of monoclonal protein using standard serum IFE, serum protein electrophoresis (SPE) and measurement of SFLC. Data were analysed retrospectively.
    Results: Specificity and sensitivity of abnormal SFLC-ratios for the detection of monoclonal protein using IFE were 96% and 41%, respectively. Eighteen patients with negative monospecific and Bence Jones IFE, but abnormal SFLC-ratios were identified. In most cases, this could be attributed to kidney and inflammatory disease or haematological disorders. In four cases, this resulted in further diagnostic investigation and light chain disease was later detected in two cases. Light chain disease was confirmed in one case but not confirmed in the other patient. In 14 patients, Bence Jones IFE was negative, although the concentrations of SFLC suggested the presence of monoclonal Bence Jones protein at concentrations detectable by IFE. Thus, either the anti-serum failed at detection, there was polymerisation of the free light chains or the SFLC assay overestimated protein concentrations. Simulating a work-up that included IFE only if abnormalities were detected by SPE or the SFLC assay would have resulted in 26% fewer IFEs being performed, but three patients with monoclonal proteins by IFE would have been missed.
    Conclusions: Abnormal SFLC concentrations are neither sensitive nor specific for the detection of monoclonal proteins by IFE. Not all PCD are accompanied by excessive production of SFLC, and several other conditions, such as renal disease are associated with increased SFLC concentrations. An abnormal SFLC-ratio is a specific marker for PCD, and occurs primarily in patients with haematological disease. If renal and inflammatory diseases are excluded, this should prompt further diagnostic investigation. Screening of serum without performing an IFE as a standard procedure leads to a reduction of sensitivity when compared to screening of serum that includes IFE.

    Abstract Large deletions that are associated with insertions of Alu-derived sequence represent a rare, but potentially unique class of alterations. Whether they form by a one-step mechanism or by a primary insertion step followed by an independent secondary deletion step is not clear. We resolved two disease-associated SPAST deletions, which involve distinct exons by long range PCR. Alu-derived sequence was observed between the breakpoints in both cases. The intronic regions that represent the targets of potentially involved Alu retrotransposition events overlapped. Microsatellite- and SNP-based haplotyping indicated that both deletions originated on one and the same founder allele. Our data suggest that the deletions are best explained by two-step insertion-deletion scenarios for which a single Alu retrotransposition event represents the shared primary step. This Alu then mediated one of the deletions by non-homologous end joining and the other by non-allelic homologous recombination. Our findings thus strongly argue for temporal separation of insertion and deletion in Alu insertion-associated deletions. They also suggest that certain Alu integrations confer a general increase in local genomic instability, and that this explains why they are usually not detected during the probably short time that precedes the rearrangements they mediate.
