Evaluation of serum chemokine RANTES concentration as a biomarker in the diagnosis of early-onset severe infections in neonates.

Objective: Only a few studies on improving the early diagnosis of severe neonatal infections have focused on the role of serum RANTES concentration (sRC). The aim of the study was to establish sRC in neonates with early-onset infections, according to their gestational age, sex, birth asphyxia, mode of delivery and value of some biochemical and hematological parameters.

Material/methods: The analysis comprised 129 neonates, including 89 infected (52 preterm, 37 full-term; 43 with sepsis, 39 with congenital pneumonia, 7 with severe urinary tract infection) and 40 healthy (control group, 25 full-term, 15 preterm).

Geospatial clustering of gastroschisis in Poland: Data from the Polish Registry of Congenital Malformations (PRCM).

Objectives: The aims of this study were: to evaluate the prevalence of abdominal wall defects in the Polish population, to analyze temporal trends in the prevalence, to identify areas (clusters) of high risk of abdominal wall defects, and to characterize, with respect to epidemiology, children with abdominal wall defects and their mothers in the area defined as a cluster.

Material And Methods: We used isolated congenital malformations (gastroschisis Q79.3 and omphalocele Q79.

The first de novo non-mosaic 14q11.2q13.1 tetrasomy of paternal origin.

Tetrasomy 14q11q13 is a very rare chromosome aberration. So far, only five patients with such an imbalance were described. All these patients had a de novo marker chromosome idic(14)(q13) leading to a partial tetrasomy of chromosome 14.

Spatial and temporal clustering of isolated cleft lip with or without cleft palate in Poland.

Background: Geographic variation in the prevalence of isolated cleft lip with or without cleft palate may be due to exogenous environmental factors or genetic variation. In this study, we aim to evaluate the prevalence of isolated cleft lip with or without cleft palate in Polish urban and rural environments in order to identify geographic areas with high prevalence (defect clusters).

Methods: We use all cases of congenital malformations reported to the Polish Registry of Congenital Malformations in the years 1998-2008 from the total population of 2,362,502 births.

Associations between endogenous dimethylarginines and renal function in healthy children and adolescents.

The structural isomer of asymmetric dimethylarginine (ADMA), symmetric dimethylarginine (SDMA), is eliminated almost entirely by urinary excretion and considered a sensitive index of glomerular filtration rate (GFR). However, reports on this relationship in healthy subjects younger than 18 years of age are rare. Therefore, our aim was to investigate relations between endogenous dimethylarginines and renal function indices in healthy children and adolescents.
