Central sleep apnea is highly prevalent in association with heart failure, some neurological diseases and chronic opioids use. There are two main categories of central sleep apnea respectively related with different underlying conditions. Some hypocapnic patients exhibit respiratory control system instability and central apnea occurs when PaCO(2) falls below the threshold for apnea during sleep. ⋯ All these patients should be assessed by recording blood gases, polysomnography and ventilatory responses to CO(2). Cardiologic assessment should include pro-brain natriuretic factor (pro-BNP) and cardiac echography whereas neurological examination requires brain imaging and/or electromyography. Ventilatory supports used for treating central sleep apnea are non-invasive ventilation and servo-assisted ventilation in hypercapnic and hypocapnic patients respectively.

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.
