Computed tomography (CT) and magnetic resonance imaging (MRI) can provide detailed anatomic structures and quantitative function information for chronic obstructive pulmonary disease (COPD). ⋯ There were different features and correlations between PFT, CT volume and MR perfusion in different phenotype, indicating each phenotype may have novel imaging method guiding clinical management.

Multicenter Study
Spirometric reference values for healthy nonsmoking Saudi adults.
To derive prediction equations of spirometric values of healthy Saudi adults and to compare the derived equations with equations reported in selected population. ⋯ The reference spirometric values derived in our study were significantly lower than the predicted values derived by the American equations.

Randomized Controlled Trial Comparative Study
Comparison of dexmedetomidine and sufentanil for conscious sedation in patients undergoing awake fibreoptic nasotracheal intubation: a prospective, randomised and controlled clinical trial.
Fibreoptic intubation is a valuable technique for difficult airway management in which conscious sedation is paramount. ⋯ DEX provides better nasotracheal intubation conditions, improves patients' tolerance to intubation and leads to lower occurrence of hypertension, respiratory depression and throat pain and post-surgical memory score for sedation during awake fibreoptic nasotracheal intubation.

Pneumonia is often diagnosed among patients hospitalized with acute exacerbations of chronic obstructive pulmonary disease (AECOPD). The aims of this study were to find the proportion of patients with pneumonia among admissions due to AECOPD and whether pneumonia has impact on the length of stay (LOS), usage of non-invasive ventilation (NIV) or the in-hospital mortality. ⋯ In-hospital morbidity, but not mortality, was increased among admissions with pAECOPD compared to npAECOPD. This may, in part, be explained by the extensive treatment with antibiotics and NIV in patients with pAECOPD.

Computed tomography pulmonary arterial obstruction index ratio (CTPAOIR) is related with the severity of pulmonary embolism (PE). Platelet indices including mean platelet volume (MPV), platelet distribution width (PDW) are reported to be increased in acute PE. ⋯ Platelet indices, MPV and PDW, can be used for the determination of disease severity, and lead to therapeutic strategies for PE patients.
