High Yield of Chest X-ray in the Follow-Up of Colorectal Cancer.

Purpose: Worldwide, colorectal carcinoma (CRC) has a high incidence and a substantial cancer-related mortality. The recurrence risk is 30-50% and lung metastases are common. Treatment of lung metastases with stereotactic ablative radiotherapy (SABR) or metastasectomy may increase survival.

A 20-Year-Old Woman With Thoracic Pain and Progressive Dyspnea on Exertion.

A 20-year-old woman presented with dry cough, right-sided thoracic pain, and gradually progressive dyspnea on exertion. She had no hemoptysis or fever. There was no relevant medical history.

Feasibility of volatile organic compound in breath analysis in the follow-up of colorectal cancer: A pilot study.

Background: Colorectal carcinoma (CRC) has a worldwide incidence of 1.4 million patients and a large share in cancer-related mortality. After curative treatment, the risk of recurrence is 30-65%.

Effect of theophylline on cortisol plasma concentrations in patients with chronic obstructive pulmonary disease.

To further understand the therapeutic action of theophylline, we investigated, in a randomized double-blind crossover study, the effects of a 4-day treatment with two different dosage regimens of theophylline on the circadian rhythm of cortisol plasma concentrations in seven COPD patients. Both theophylline regimens resulted in plasma concentrations in the therapeutic range (more than 7.5 mg/l).

Chronopharmacodynamics and kinetics after symmetric and asymmetric multiple theophylline doses in patients with chronic obstructive pulmonary disease.

In a randomized double-blind crossover study, the effects of 4 days of symmetric or asymmetric dosing with sustained-release theophylline (Sabidal-SR) were compared with placebo in ten patients with chronic obstructive pulmonary disease in a stable state. The doses were 450 mg b.i.

A placebo-controlled comparison between the bronchodilatory effects of ipratropium bromide inhaled as a dry powder and by metered dose inhaler in chronic obstructive pulmonary disease.

A placebo-controlled study was performed to compare the effect of the inhalation of ipratropium bromide as a powder (capsule = 40 micrograms) and by pressurized aerosol (two puffs of 20 micrograms; ie, 40 micrograms). Fifteen patients (nine males and six females) with chronic obstructive pulmonary disease were studied in a double-blind crossover comparison of the two different modes of administration. The VC, FEV1 and viscous work of breathing time-response curves were almost identical, indicating bronchodilation.

Moderately severe chronic airflow obstruction. Can corticosteroids slow down obstruction?

In a former study in patients with severe chronic airflow obstruction (CAO), (forced expiratory volume in one second (FEV1) ranging from 350-910 ml), we concluded that daily oral corticosteroids might slow down the progression of disease. The results of the present long-term (14-20 yr) study on 139 non-allergic patients with less severe CAO (FEV1 greater than or equal to 1200 ml, FEV1 as a percentage of vital capacity (FEV1%VC) 40-55%) confirm and extend our former observations. Four patterns of the course of FEV1 and inspiratory vital capacity (VC) in time were recognized: 1) linear decrease; 2) no change; 3) initial increase, followed by decrease; 4) initial decrease, followed by increase.

Ear oximetry studies during sleep in patients with severe chronic obstructive pulmonary disease in a stable state.

Changes in ear oxygen saturation (SaO2) during the night were measured in 12 elderly patients (mean age = 63.4 +/- 6.7 years) with stable severe chronic obstructive pulmonary disease.

Severe chronic airflow obstruction: can corticosteroids slow down progression?

A long-term (14-18 yr) prognostic study on patients with severe Chronic Airflow Obstruction (CAO) (FEV1 less than 1000 ml) is reported. In 65 of the 79 patients under study at least 7 serial FEV1 values were available. At the beginning of the study long-term treatment with oral prednisolone in doses of 10-15 mg/d was started.

Comparison of disodium cromoglycate, terbutaline and thiazinamium in the prevention of exercise-induced asthma and its relation to non-specific bronchial responsiveness.

The protective effect of pre-exercise treatment with disodium cromoglycate (DC), terbutaline sulphate (TS) and thiazinamium methylsulphate (TM) on exercise-induced asthma (EIA) was investigated. Thirty-one adults each exercised for over 6 min on a bicycle ergometer. Each subject performed five tests.

Prognosis in severe chronic obstructive pulmonary disease with regard to the electrocardiogram.

A long-term prognostic study of 128 patients with severe chronic obstructive pulmonary disease (initial value for Forced Expiratory Volume in one second, [FEV1] less than or equal to 1,000 ml) with regard to electrocardiographic and lung function parameters as obtained at the entry visit is reported. Many initial ECG-variables and lung function parameters were significantly different between survivors and non-survivors after five years. We used a discriminant analysis to determine which factors actually provided independent information for detection of those subjects with a survival less than five years.

Prognosis in severe chronic obstructive pulmonary disease.

A long-term prognostic study of 129 patients with severe chronic obstructive pulmonary disease (initial value for forced expiratory volume in 1 sec [FEV1] smaller than or equal to 1,000 ml) is reported. Data from the patients (72 per patient) were obtained in a clinically stable phase during the first hospital admission and subsequent regular outpatient visits; the data were processed using multiple regression and discriminant analysis. Five- and 10-year cumulative survival rates were 69 and 40 per cent, respectively.

Exercise-induced airway obstruction in relation to chronic obstructive lung disease.

16-20. Forty-two patients with chronic obstructive lung disease and clinically suspected exercise-induced airway obstruction were studied to ascertain whether those with proven exercise-induced airway obstruction had specific distinguishing features. Exercise-induced airway obstruction (defined as a fall of FEV of at least 10% of the pre-exercise values) was detected in 20 of the 42 patients.
