In this study the authors investigated whether expiratory flow limitation (FL) is present during tidal breathing in patients with bilateral bronchiectasis (BB) and whether it is related to the severity of chronic dyspnoea (Medical Research Council (MRC) dyspnoea scale), exercise capacity (maximal mechanical power output (WRmax)) and severity of the disease,(More)
BACKGROUND Limited information exists regarding the development of pulmonary hypertension in patients with obstructive sleep apnea (OSA) in the absence of lung and heart comorbidity. OBJECTIVES The aims of this study were to investigate whether OSA patients without any other cardiac or lung disease develop pulmonary hypertension, and to assess the effect(More)
There is limited information on the development of left ventricular (LV) dysfunction in patients with obstructive sleep apnoea (OSA) in the absence of lung and cardiac comorbidity. This study aimed to investigate whether OSA patients without heart morbidity develop LV dysfunction, and to assess the effect of continuous positive airway pressure (CPAP) on LV(More)
BACKGROUND AND STUDY OBJECTIVE Phrenic nerve injury may occur after cardiac surgery; however, its cause has not been extensively investigated with electrophysiology. The purpose of this study was to determine by electrophysiologic means the importance of various possible risk factors in the development of phrenic nerve dysfunction after cardiac surgical(More)
CYFRA 21-1 was evaluated in 115 untreated patients with malignant pleural effusions (96 with primary lung cancer and 19 with non lung cancer) and 99 patients with benign pleural effusions. The levels of pleural fluid CYFRA 21-1 were from 1 to 385 times higher than those in serum, in all the examined patients. The mean level of pleural fluid CYFRA 21-1 was(More)
Patients with bronchial asthma were compared with physically ill patients as to personality traits and dysthymic states. Asthmatics were less dominant and more intropunitive, more anxious and more depressed than the control group. Low dominance or dependent social attitude and inhibited hostility was correlated with low vital capacity (FVC).
Tumour necrosis factor (TNF) and interleukin-1 (IL-1) are powerful mediators with a key role in inflammation. This study was undertaken to study the presence of TNF and IL-1 in tuberculous effusion where there is marked inflammation and where examination of the pleural fluid may give information about the local inflammatory reaction. Adenosine deaminase(More)
The lack of methodology for measuring the alveolar carbon dioxide tension (PA,CO2) has forced investigators to make several assumptions, such as that PA,CO2 is equal to end-tidal (PET,CO2) and arterial CO2 tension (Pa,CO2). The present study measured the mean PA,CO2 and Bohr's dead space ratio (Bohr's dead space/tidal volume (VD,Bohr/VT)) during tidal(More)
Recently, we have shown that the expired CO2 gas volume versus tidal volume (VCO2-VT) curve is a useful tool for assessing unevenness of ventilation because it allows the separation of tidal volume into three functional compartments: (a) the CO2-free expired air (V0), (b) the transitional volume (Vtr), (c) the alveolar volume (VA) and the measurement of(More)
