Comparative StudyEffects of air pollution on growth in schoolchildren.
The growth is considered a very sensitive indicator of the impact of environment of the health status of children. The aim of the study was to investigate whether air pollution is related to children's growth. The subjects were 1059 pupils, aged 7-11 years, living for more than ten years in the same home in the city of Nis (Serbia). ⋯ Air pollution is associated with children's height and weight, specially before the age of 9 years. There was a significant difference in the prevalence of thinness in children exposed to higher concentrations of air pollutants (p = 0.038). It might be possible that air pollution negatively contributed to the growth rate in urban children.

Importance of interleukin 6 in pathogenesis of inflammatory bowel disease.
Inflammatory bowel disease (IBD), encompassing ulcerative colitis (UC) and Crohn's disease (CD), is an uncontrolled chronic inflammation of the gastrointestinal tract caused by an interaction of diverse genes and environmental factors. There is growing evidence that cytokine production plays an important role in IBD. One of the key roles in signaling pathway in development of IBD is performed by interleukin 6 (IL-6), although molecular mechanism of this pathway is not yet fully understood. ⋯ Quantitative assessment of serum IL-6 was performed with solid-phase, enzyme-labeled, chemiluminescent sequential immunometric assay. Our results indicate that serum IL-6 is a clinically relevant parameter for CD and UC that strongly correlates with inflammatory activity of disease. We confirmed and extended the role of cytokine production patterns for IBD presentation in Croatian population.

ReviewAdvances in a rapidly emerging field of hair follicle stem cell research.
Human skin maintains the ability to regenerate during adulthood, as it constantly renews itself throughout adult life, and the hair follicle (HF) undergoes a perpetual cycle of growth and degeneration. The study of stem cells (SCs) in the epidermis and skin tissue engineering is a rapidly emerging field, where advances have been made in both basic and clinical research. Advances in basic science include the ability to assay SCs of the epidermis in vivo, identification of an independent interfollicular epidermal SC, and improved ability to analyze individual SCs divisions, as well as the recent hair organ regeneration via the bioengineered hair follicular unit transplantation (FUT) in mice. ⋯ The study of the HF stem cells (HFSCs) started by identification of epidermal SC in the HF bulge as quiescent "label retaining cells". The research of these cells emerged rapidly after the identification of bulge cell molecular markers, such as keratin 15 (K15) and CD34 in mice and CD200 in humans, which allowed the isolation and characterization of bulge cells from follicles. This paper provides an overview of the current knowledge on epidermal SCs in the HF describing their essential characteristics and the control of follicle SCs fate, their role in alopecia, as well as their use in tissue engineering.

Clinical TrialImportance of determination of urine neutrophile gelatinase associated lipocalin in early detection of acute kidney injury.
Acute kidney injury (AKI) is a complex, frequent and serious clinical problem with high rate of mortality. Therefore there is a serious need for early detection of AKI, with a tendency to detect early stage--RISK dut to start with therapy as soon as possible and prevent irreversible changes in renal function. Study's purposes were to explore the rhythm of urine neutrophile gelatinase associated lipocalin (urine NGAL) concentration changes before and after cardiovascular surgery and compare results of urine NGAL values with results of serum creatinine and creatinine clearance as main diagnostic indicators of renal function in order to define role of urine NGAL biomarker in early diagnosis of acute kidney injure. ⋯ By using of automated urine NGAL test detection of acute kidney injure is posible 24-48 hours earlier comparing with actual results acquired by determination of serum creatinine concentration. The results of this study will indicate urine NGAL as a reliable biomarker of early acute kidney injure. A combination of early and late markers of kidney damage (urine NGAL, serum creatinine) can greatly contribute to better control the outcome of all those who are a risk group for the development of AKI.

Case ReportsOvarian torsion in adolescent with chronic immune thrombocytopenia.
Ovarian torsions in adolescence are rarity, particularly bilateral, with mostly unknown etiology. Enlargement of the ovary contributes to torsion. Young girl presenting with abdominal pains, nausea and vomiting was for two days suspected and observed as gastroenteritis. ⋯ Thrombocytopenia in adolescence requires additional attention as possible cause of intra-ovarian bleeding with consecutive enlargement and may lead to torsion. Oral contraceptives regulate dysfunctional bleeding, decrease ovarian volume and by so, may minimize risk of torsion. This strategy proved effective in the case we present.
