Isolated diaphragm weakness and the diagnostic value of phrenic nerve stimulation.

Acute onset, atraumatic, bilateral diaphragm paralysis due to isolated bilateral phrenic neuropathy is uncommon.

Australia-wide cross-sectional survey of general practitioners' knowledge and practice of lung cancer screening.

Background: Low-dose computed tomography (LDCT) screening can reduce lung cancer deaths in high-risk individuals, yet current Australian guidelines do not recommend screening. Little is known about current screening practices in Australia.

Aim: To evaluate the proportion of general practitioners who report ordering lung cancer screening for their patients, identify factors associated with ordering lung cancer screening and assess general practitioners (GP) rationale for recommending screening and preference of composition of any future national targeted screening programme.
