Myelodysplastic syndrome (MDS) is a clonal stem cell disorder frequently associated with inefficient granulopoiesis showing dysplastic polymorphonuclear neutrophils (PMNs). To assess PMN functionality in MDS in a clinical routine setting, 30 MDS patients and ten healthy volunteers were analyzed for PMN and monocyte phenotype and function (degranulation, CD62L shedding, oxidative burst and phagocytosis) upon stimulation with lipopolysaccharide by multi-color flow cytometry (MCFC). Our data show a heterogeneous pattern for CD66, CD16 and CD64 expression on PMNs of MDS patients. CD62L shedding rate and CD66 degranulation were reduced. Interestingly, we detected correlations between the WHO adapted prognostic scoring system (WPSS) and CD16 expression on PMNs as well as the international prognostic scoring system (IPSS) and CD11b degranulation by MCFC, suggesting clinical relevance of MCFC based function testing. In conclusion, MCFC of myelodysplastic immunophenotypes and PMN functionality are applicable in clinical settings, but further prospective studies are needed to assess the practical clinical value of such analyses., (Copyright © 2016 Elsevier Inc.

Introduction: The risk of infectious complications after water birth which might be due to water contaminated by faecal bacteria or environmental microbes from the water supply system is still in discussion., Materials and Methods: We performed a microbiological study comparing neonatal bacterial colonisation after water birth to conventional bed deliveries with or without relaxation bath. In all three groups (96 deliveries) we isolated most frequently from ear and palate of the newborns Staphylococcus epidermidis, E. coli and enterococci, which belong to the normal vaginal flora., Results: Neonatal outcome, infantś and maternal infection rate did not differ between the three groups.
