    (2010) Duzova A.; Bakkaloglu A.; Kalyoncu M.; Poyrazoglu H.; Delibas A.; Ozkaya O.; Peru H.; Alpay H.; Soylemezoglu O.; Gur-Guven A.; Bak M.; Bircan Z.; Cengiz N.; Akil I.; Ozcakar B.; Uncu N.; Karabay-Bayazit A.; Sonmez F.
    The aim of this prospective, multicenter study was to define the etiology and clinical features of acute kidney injury (AKI) in a pediatric patient cohort and to determine prognostic factors. Pediatric-modified RIFLE (pRIFLE) criteria were used to classify AKI. The patient cohort comprised 472 pediatric patients (264 males, 208 females), of whom 32.6% were newborns (median age 3 days, range 1-24 days), and 67.4% were children aged>1 month (median 2.99 years, range 1 month-18 years). The most common medical conditions were prematurity (42.2%) and congenital heart disease (CHD, 11.7%) in newborns, and malignancy (12.9%) and CHD (12.3%) in children aged>1 month. Hypoxic/ischemic injury and sepsis were the leading causes of AKI in both age groups. Dialysis was performed in 30.3% of newborns and 33.6% of children aged>1 month. Mortality was higher in the newborns (42.6 vs. 27.9%; p<0.005). Stepwise multiple regression analysis revealed the major independent risk factors to be mechanical ventilation [relative risk (RR) 17.31, 95% confidence interval (95% CI) 4.88-61.42], hypervolemia (RR 12.90, 95% CI 1.97-84.37), CHD (RR 9.85, 95% CI 2.08-46.60), and metabolic acidosis (RR 7.64, 95% CI 2.90-20.15) in newborns and mechanical ventilation (RR 8.73, 95% CI 3.95-19.29), hypoxia (RR 5.35, 95% CI 2.26-12.67), and intrinsic AKI (RR 4.91, 95% CI 2.04-11.78) in children aged >1 month. © 2010 IPNA.

    Socio-demographic and clinical characteristics of Turkish workers with pneumoconiosis
    (Czech National Institute of Public Health, 2016) Altınöz H.; Çelikkalkan C.; Horasan G.D.; Hamşioğlu F.; Cengiz N.; Orbay H.
    Aim: Pneumoconiosis is caused by inhaling dust. The aim of the study was to analyze 208 cases of workers’ pneumoconiosis. Method: Patients’ files were used for the descriptive study. Results: All patients were male aged 38.82 ± 13 years. The most important symptom was breathlessness. Patients were denim sandblasters (50.5%), dental technicians (12%), coal miners (6.7%), and others. The mean exposure time before pneumoconiosis occurred was shorter in denim sandblasters and teflon kitchenware producers compared to other occupations (5.4 ± 4.2 and 4.5 ± 3.3 years, respectively). Profusion (76.5%) was more than 1/2 by the International Labour Organization (ILO) classification. Pulmonary function tests were negatively correlated with profusion. Conclusion: Denim sandblasters and teflon kitchenware producers have less exposure time before pneumoconiosis occurs and they become symptomatic earlier. As Turkish workers suffering from pneumoconiosis are younger, measures to prevent pneumoconiosis must be the priority of the healthcare authorities. © National Institute of Public Health, Prague 2016.
