Sickle cell disease is a common but often poorly understood by chest physicians. The acute chest syndrome represents its main respiratory complication. ⋯ Acute chest syndrome is a severe respiratory complication of sickle cell disease. Therapeutic measures are simple but undervalued.

[Pulmonary arterial hypertension related to HIV: is inflammation related to IL-6 the cornerstone?].
Vascular diseases have become the leading cause of mortality in the population treated for HIV infection. Pulmonary arterial hypertension (PAH) related to HIV (PAH-HIV), the fourth cause of PAH in France, has the same histological pattern as other PAH from the group 1 of Dana Point classification. But, conversely to idiopathic PAH in the general population, PAH-HIV is particular by its high frequency in HIV-infected population. ⋯ This inflammation mainly involves the endothelin-1 pathway, which has an action on endothelium and macrophages, leading to high production of IL-6. Moreover, plasmatic level of IL-6 has a prognostic value in PAH-HIV, independently from conventional (functional or hemodynamic) parameters. The use of endothelin receptor antagonist permits major effect on IL-6 production and dramatic effect on PAH in so-called "bosentan responders".

Sarcoidosis is a juvenile systemic granulomatosis. Its polymorphic clinical presentation depends on its different localisations, thoracic and extrathoracic. The role of imaging is very important for all localisations; but for mediastinopulmonary involvement, which is the most frequent (>90% of cases), it plays a major role in detecting the disease, diagnosing it, its prognosis, decision-making regarding treatment of it and in the monitoring of its development. ⋯ Elsewhere, it highlights irreversible fibrous lesions: hilar peripheral linear opacities; septal linear opacities; bronchial distortion, honeycomb destruction or even perihilar fibrotic masses. Less frequently we can visualise bronchiolar or cystic involvement. Benign in most cases, the sarcoidosis prognosis becomes bleaker in the event of hemoptysis, Aspergillus colonisation or before the onset of pulmonary hypertension.

In armed conflicts and during terrorist attacks, explosive devices are a major cause of mortality. The lung is one of the organs most sensitive to blasts. Thus, today it is important that every GP at least knows the basics and practices regarding treatment of blast victims. We suggest, following a review of the explosions and an assessment of the current threats, detailing the lung injuries brought about by the explosions and the main treatments currently recommended.

Review Case Reports Comparative Study
[Bronchial carcinoma and intensive care].
Lung cancer is a disease with a poor prognosis. Therapeutic innovations in oncology and the optimisation of intensive care patient management have improved the prognosis of lung cancer presenting with acute life-threatening respiratory or cardiac emergencies. ⋯ Consideration of the acute event is important when deciding whether to hospitalise a patient with lung cancer in intensive care. An early admission, if indicated, is desirable. The course in the first 72hours provides a good estimation of the patient's prognosis and helps to achieve better treatment.
