“…We propose that essential and toxic elemental measurements may be performed on patients reaching in the emergency department, to test whether the concentration of it may serve not only as markers of rheumatoid arthritis and its remedies but also as predictors of adverse outcomes. The concentrations of essential trace and toxic elements in scalp hair samples of the Irish referent subjects were close to those reported from other European (Rodushkin and Axelsson, 2000;Reilly and Harrison, 1979;Nowak and Chmielnicka, 2000;Trojanowski et al, 2010;Sturaro et al, 1993;Goulle et al, 2005), American (Nagra et al, 1992;Ryan et al, 1978;Saiki et al, 2008;DeAntonlo et al, 1982) and Australian (McKenzie, 1979) countries (Table 7). The ele-mental concentrations of Cd and Pb in Pakistani referents were al-most higher than in European countries, which is in agreement with the studies which were done in Asian (Pasha et al, 2008(Pasha et al, , 2010Shah et al, 2006;Khalique et al, 2005;Vishwanathan et al, 2002;Sukumar and Subramanian, 2003;Mehra and Juneja, 2005;Rao et al, 2002;Ashrafur et al, 2009;Sasmaz et al, 2003;Ulvi et al, 2002;Faghihian and Rahbarnia, 2002;Man and Zheng, 2002;Man et al, 1996;Sandstead et al, 1998), African (Nnorom et al, 2005;Hashem and Abed, 2007;Khuder et al, 2008;Eltayeb and Van-Grieken, 1989;Mortada et al, 2002) countries (Table 7).…”
