Mastoiditis is the result of an infection that extends to the air cells of the skull behind the ear. Specifically, it is an inflammation of the mucosal lining of the mastoid antrum and mastoid air cell system inside the mastoid process.
Extract: Government spending has increased substantially in recent years. Consequently, the breakeven oil price rose to $106 a barrel in 2014 from $69 a barrel in 2010. As a result, with the large decline in oil prices, the fiscal deficit has increased sharply and is likely to remain high over the medium-term.
From 2010 until mid-2014, world oil prices had been fairly stable, at around $110 a barrel. But since June prices have more than halved. Brent crude oil has now dipped below $50 a barrel for the first time since May 2009 and US crude is down to below $48 a barrel.rom 2010 until mid-2014, world oil prices had been fairly stable, at around $110 a barrel.
