Effect of Ambulatory Oxygen on the Respiratory Pattern during the 6 Min Walking Test in Patients with Interstitial Lung Diseases.

Introduction: Patients with pulmonary fibrosis experience early oxyhemoglobin desaturation under effort, which limits their ability to exercise and their quality of life. Recent studies have shown that in resting normoxaemic patients who become hypoxemic under exertion, administration of outpatient oxygen significantly improves stress dyspnoea and quality of life. It is unclear how this happens, since oxygen administration does not act directly on dyspnoea, and does not appear to have much effect on the heart rate and pulmonary artery pressure.

Systemic Corticosteroids for Treating Respiratory Diseases: Less Is Better, but… When and How Is It Possible in Real Life?

Systemic corticosteroids (CSs), a keystone in pulmonology, are drugs with strong antiinflammatory activity. They are cheap, easily available, and accessible, but with common and serious side effects. Moreover, the use of exogenous CSs may suppress the hypothalamic-pituitary-adrenal (HPA) axis, predisposing to adrenal insufficiency.

Relationship between great saphenous vein recanalization, venous symptoms reappearance, and varicose veins recurrence rates after endovenous radiofrequency ablation.

The term "recurrence" in chronic venous disease remains not yet well defined, despite numerous reports describing patterns and causes of the presence of recurrent varicose veins (RVVs). Moreover, saphenous trunk recanalization (STR) has also been documented as one of the major source of RVVs and it is widely used to indicate the "failure" of endovenous ablation. Finally, reappearance of venous symptoms (VSym) should be considered to reach a complete "recurrence" evaluation.

Oxygen Therapy during Exercise in Patients with Interstitial Lung Diseases.

ILDs are a varied group of diffuse parenchymal lung diseases associated with high morbidity and mortality. Current treatments can only slow their progression but not cure the disease. Other treatments such as oxygen therapy can also be used as support.
