Chronic Obstructive Pulmonary Disease (COPD) is characterized by irreversible airflow limitation in the lungs. COPD frequently coexist with Heart Failure (HF) but most patients go undiagnosed because of similarity symptoms. Data on prevalence HF are discrepant and scarce.

OBJECTIVES To investigate the etiopathogenic role of sinus inflammatory disease in primary acquired dacryocystitis and other chronic obstructive diseases of the lachrymal drainage system. STUDY DESIGN Noninterventional controlled study. SETTING Tertiary care center. SUBJECTS AND METHODS Sixty consecutive patients with primary acquired dacryocystitis and other chronic obstructive diseases ...

BACKGROUND A synchronism exists between the respiratory and cardiac cycles. However, the influence of the inspiratory muscle weakness in chronic obstructive pulmonary disease (COPD) on cardiac autonomic control is unknown. The purpose of the present investigation was to evaluate the influence of respiratory muscle strength on autonomic control in these patients. METHODS Ten chronic obstructiv...

Chronic obstructive pulmonary disease (COPD) is characterised by destruction of extracellular matrix (ECM) in parenchymal areas, whereas the bronchial walls can show fibrosis. In addition, an extensive inflammatory process is observed. CD8+ T-cells, located throughout the lung, and epithelial cells in centrally located airways, produce cytokines involved in the inflammatory process. These cytok...

The Global Initiative for Chronic Obstructive Lung Disease (GOLD) has defined stage I chronic obstructive pulmonary disease (COPD) as forced expiratory volume in one second/forced vital capacity (FEV1/FVC)% <70% and a FEV1% predicted of >80%. Stage 2 has been defined as FEV1/FVC <70% and a FEV1% pred of <80%. The authors examined the extent of COPD misdiagnosis using this definition in healthy,...

RATIONALE Low-attenuation areas assessed by computed tomography reflect the extent of pathological emphysema and correlate with airflow limitation and mortality in patients with chronic obstructive pulmonary disease. The cumulative size distribution of low-attenuation area clusters follows a power law characterized by an exponent, D. The values of D reflect the complexity of the terminal airspa...

OBJECTIVE To evaluate the presence and severity of symptoms of anxiety and depression in individuals with asthma or chronic obstructive pulmonary disease. METHODS In order to evaluate symptoms of anxiety and depression, specific instruments of quantification (the State-Trait Anxiety Inventory and the Beck Depression Inventory, respectively) were administered to patients at an outpatient clini...
