Gas exchange abnormalities occur firstly during sleep in restrictive and obstructive chronic respiratory failure. Nocturnal hypoxemia is often a revealing feature of a sleep-related hypoventilation/hypoxemia syndrome in patients who will have later a diurnal hypoxemia. On the other hand, sleep may induce breathing abnormalities in individuals without lung diseases, like in obstructive sleep apnea syndrome (OSAS). ⋯ These features are believed to be related to both sleep fragmentation and nocturnal hypoxia/hypercapnia. Sleep-related hypoventilation/hypoxemia and pharyngeal obstructive events may occur together in patients with respiratory insufficiency, especially in obese and/or chronic obstructive pulmonary disease (COPD) subjects. A correct qualitative and quantitative assessment of sleep-disordered breathing may only be performed by recording specific physiological signals during sleep.

Efficacy and tolerance of home non-invasive ventilation (NIV) must be assessed by using objective criteria (clinical evaluation, arterial blood gases, oxymetry, and research of side effects such as air leaks, skin problems, etc). In this article, we describe a procedure for long-term follow-up of home NIV. We also suggest an algorithm using available polygraphic tools to ascertain causes of NIV failure, in order to correct them.

Intratracheobronchial foreign bodies are common accidents in children. In developed countries, the removal of these intratracheobronchial foreign bodies is performed with flexible or rigid fiberoptic bronchoscopy. Resorting to surgery is rare. ⋯ Removal alternatives are necessary in order to avoid sanitary evacuation which is not always within patients' means. In this study, the authors describe the removal of an intratracheobronchial foreign body opaque to X-rays with foreign body forceps. The forceps, passed through the orotracheal intubation probe, were guided by an image intensification system in a traumatology operating theatre.

Case Reports
[A late post-traumatic diaphragmatic hernia revealed by a tension fecopneumothorax (a case report)].
Post-traumatic diaphragmatic hernia is a particular lesion in traumatology that may be neglected. Thus, the diagnosis may be delayed for a few days to several months and only be made following a complication. The left diaphragmatic cupola is the most touched. Tension fecopneumothorax following diaphragmatic hernia perforation in the pleural cavity is a rare but particularly severe complication of traumatic diaphragmatic hernia. ⋯ The possibility of diaphragmatic hernia should be kept in mind in case of violent blunt thoraco-abdominal traumatism or basithoracic wound. In this way, complications such as tension fecopneumothorax that could threaten the functional and vital prognosis may be prevented.
