Reamed femoral nailing in sheep: does irrigation and aspiration of intramedullary contents alter the systemic response?
It appears that, in the presence of a unilateral pulmonary injury, the systemic effects of intramedullary reaming of an intact femur can be minimized with use of a modified reamer design that simultaneously irrigates the canal and removes debris. Additional clinical validation of this reaming system is necessary.
This study suggests that ETS modifies the acute effects of low-level ambient PM(2.5) exposure on childhood asthma. This negative interaction, the smaller effect of particulate matter exposure in children exposed to higher ETS, may be related to a nonlinear dose-response relationship between asthma mediators and particulate exposures.
