In patients who do not succumb early to ARF of severe malaria, treatment with antimalarials and dialysis brings about recovery of renal function.

CD23 and FMC-7 are normal B-cell antigens used during diagnostic immunophenotyping of suspected lymphoproliferative disorders, but the diagnostic usefulness of antigenic expression patterns of simultaneous 2-color staining and flow cytometric analysis has not been reported. We evaluated the FMC-7 and CD23 expression pattern in 201 cases of B-cell lymphoma from tissue biopsy specimens by multiparameter flow cytometry. The CD23-/FMC-7+ pattern was the most common pattern in large cell, mantle cell, and marginal zone lymphomas. The CD23 and FMC-7 antigen, along with the CD5 coexpression pattern, permitted accurate classification of all 71 cases of small lymphocytic, mantle cell, and marginal zone types of lymphoma. The widest variation of patterns was with follicular cell lymphoma, although most cases expressed the CD23 +/-/FMC-7+ pattern (+/-, partial or minor subset expression). The CD23 and FMC-7 antigen expression pattern was predictive of subtypes in more than 95% of lymphoma cases and could narrow the differential diagnosis in the remaining cases. We conclude the flow cytometric CD23/FMC-7 expression pattern achieved by dual staining facilitates accurate and reproducible classification of B-cell lymphomas and has diagnostic usefulness.

BackgroundPreterm birth (PTB), birth at <37 weeks of gestation, is a significant global public health problem. World-wide, about 15 million babies are born preterm each year resulting in more than a million deaths of children. Preterm neonates are more prone to problems and need intensive care hospitalization. Health issues may persist through early adulthood and even be carried on to the next generation. Majority (70 %) of PTBs are spontaneous with about a half without any apparent cause and the other half associated with a number of risk factors. Genetic factors are one of the significant risks for PTB. The focus of this review is on single nucleotide gene polymorphisms (SNPs) that are reported to be associated with PTB.ResultsA comprehensive evaluation of studies on SNPs known to confer potential risk of PTB was done by performing a targeted PubMed search for the years 2007–2015 and systematically reviewing all relevant studies. Evaluation of 92 studies identified 119 candidate genes with SNPs that had potential association with PTB. The genes were associated with functions of a wide spectrum of tissue and cell types such as endocrine, tissue remodeling, vascular, metabolic, and immune and inflammatory systems.ConclusionsA number of potential functional candidate gene variants have been reported that predispose women for PTB. Understanding the complex genomic landscape of PTB needs high-throughput genome sequencing methods such as whole-exome sequencing and whole-genome sequencing approaches that will significantly enhance the understanding of PTB. Identification of high risk women, avoidance of possible risk factors, and provision of personalized health care are important to manage PTB.Electronic supplementary materialThe online version of this article (doi:10.1186/s12864-016-3089-0) contains supplementary material, which is available to authorized users.

Background: In this study we compared clinical findings with flow cytometric immunophenotypic results in a series of patients with aggressive and indolent gamma delta T-cell malignancies with peripheral blood and/or bone marrow involvement.Methods: Gamma delta T-cell malignancies were detected based on flow cytometric demonstration of an abnormal T-cell population staining positive with T-cell receptor gamma delta and confirmed by morphologic and clinical reviews. Clinical data were obtained through chart review and discussion with the patients' physicians.Results: Blood or bone marrow involvement was present in all patients. Hepatosplenic and cutaneous gamma delta T-cell lymphomas had an aggressive clinical course, whereas the gamma delta T-cell large granular lymphocyte (LGL) leukemias had an indolent course. Expressions of CD5, CD8, CD16, and CD57 differed in gamma delta T-cell LGL leukemia compared with hepatosplenic and cutaneous gamma delta T-cell lymphomas.Conclusions: Gamma delta T-cell malignancies have a poor prognosis with the exception of gamma delta T-cell LGL leukemia (indolent process). Because CD57 expression is specific for gamma delta T-cell LGL leukemias, expression of this antigen may be associated with a more indolent clinical course. Because cutaneous gamma delta T-cell lymphoma can present with peripheral blood involvement, flow cytometric evaluation of peripheral blood is important in staging these patients.
