Multicenter Study Comparative Study[Comparison of the Asthma Control Test (ACT) with lung function, levels of exhaled nitric oxide and control according to the Global Initiative for Asthma (GINA)].
The current goal of asthma treatment is to achieve and maintain control. This study aimed to explore the relationship between the ACT (Asthma Control Test) questionnaire and the levels of control according to GINA (Global Initiative for Asthma) to establish the cut-off points for the ACT and evaluate its relationship with lung function and fractionated exhaled nitric oxide level (FeNO). ⋯ The cut-off points would be, for controlled asthma ACT> or =21, partly controlled asthma ACT=19-20 and uncontrolled asthma ACT< or =18. A more complete assessment would require including monitoring operating parameters and FeNO.

Review[Permissive and non-permissive hypercapnia: mechanisms of action and consequences of high carbon dioxide levels].
Acute lung injury is a disease with high incidence of mortality and its treatment is still controversial. Increasing the levels of CO2 beyond the physiological range has been proposed as a potential protective strategy for patients on mechanical ventilation, as it could moderate the inflammatory response. In this article we review the published evidence on the role of CO2 during acute lung injury. We conclude that although there are reports suggesting benefits from hypercapnia, more recent evidence suggests that hypercapnia could be deleterious, contributing to worsening of the lung injury.

Case Reports[Unilateral painful diaphragm paralysis as the only sign of amyotrophic neuralgia].
Amyotrophic neuralgia is an inflammatory and idiopathic neuropathy which is characterised by neuropathic pain. It was described for the first time in 1948 as condition that only affected the brachial plexus and was called Parsonage-Turner syndrome. Although this syndrome is more common in the brachial plexus, it can concomitantly, or in isolation affect the phrenic nerve, and in this case the diagnosis is very difficult if there is no high clinical suspicion. We present a case of a patient with amyotrophic neuralgia in which the only sign was left phrenic involvement, and we highlight the resistance of the pain to analgesics, as well as the persistence of the symptoms and diaphragm problems for over 6 months.
