The Chronic Obstructive Pulmonary Disease (COPD) Assessment Test (CAT) is a quality-of-life (QOL) questionnaire that proved to correlate with St. George's Respiratory Questionnaire. Correlations between CAT scores and other COPD parameters have not been thoroughly evaluated in Japanese outpatients. ⋯ The CAT score, which is obtainable by a simple questionnaire originally designed for QOL assessment, had strong correlations with airflow obstruction, dyspnea, exercise tolerance, prognostic index and oxygenation in Japanese outpatients.

Comparative Study Observational Study
Comparison of clinical characteristics in patients with obesity hypoventilation syndrome and obese obstructive sleep apnea syndrome: a case-control study.
Obesity hypoventilation syndrome (OHS) can be overlooked unless clinicians have a high index of suspicion. The present case-control study aimed to compare characteristics of patients with OHS and obese obstructive sleep apnea syndrome (OSAS), and to identify determinants of hypercapnia in OSAS patients. ⋯ It was shown that OHS patients have increased rate of hypertension, daytime sleepiness and HCO3 , and decreased lung functions and PaO2 levels than OSAS patients. The present results support that elevated bicarbonate levels and decreased oxygen saturations in obese OSAS patients should prompt clinicians to predict OHS.

In children, coughs lasting longer than 4 weeks are considered to be chronic, with etiological factors varying widely. ⋯ The use of a standardized clinical approach such as the ACCP increases the possibility for fast and accurate diagnosis during the treatment of children with chronic cough, and the use of these guidelines should be required.

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.
