[Physiologic responses to walking and cycling in patients with chronic bronchial obstruction].

Introduction: In patients with bronchial obstruction, desaturation is more important during walking than cycling. For other effort parameters, studies report conflicting data.

Objective: Comparing different responses (desaturation, tachycardia, tachypnea, dyspnea) to the 6 minutes walking test (WT6) and to cycling at 25 watts for 10 minutes (CT) in patients with COPD or asthma and assessing the correlation between these responses and functional parameters at rest.

[Preoperative rehabilitation in the surgical treatment of lung cancer].

Objective: The aim of this study is to evaluate the effect of preoperative rehabilitation on operability and postoperative outcome in patients with lung cancer.

Methods: We studied retrospectively 27 patients who underwent respiratory rehabilitation for 4 weeks prior to lung cancer resection and 26 patients who were operated without previous rehabilitation (control group). Spirometry, arterial blood gases, and exercise tests with maximum oxygen consumption (VO2max) were assessed pre and postoperatively.

[Respiratory manifestations in von Recklinghausen's disease].

The neurofibromatosis type I (NF I, von Recklinghausen's disease) is an autosomal dominant neurocutaneous disorder with systemic involvement. The respiratory manifestations include: chest wall deformities, upper airway obstruction by neurofibromas, parenchymal neurogenic tumours, pulmonary fibrosis, cystic lung disease, primary pulmonary hypertension, central hypoventilation, diaphragm paralysis. We present 4 cases of NF I associated with chronic respiratory diseases.
