[The syndrome of increased upper airways resistance: What are the clinical features and diagnostic procedures?].

The upper airway resistance syndrome "UARS" is a poorly defined entity, often described as a moderate variant of the obstructive sleep apnea syndrome. It is associated with respiratory effort-related arousal, absence of obstructive sleep apnea, and absence of significant desaturation. It is a relatively common condition that predominantly affects non-obese young adults, with no predominance in either sex.

[Combined pulmonary fibrosis and emphysema associated with microscopic polyangiitis].

Background: Combined pulmonary fibrosis and emphysema (CPFE) is a rare entity of unknown etiology. It usually occurs in the context of smoking and, less commonly, connective tissue disease. However, it has been rarely previously described in the context of vasculitis.

[Intra-alveolar hemorrhage: rare presentation of fat pulmonary embolism].

Introduction: Fat embolism syndrome is a severe complication of long bone fractures, corresponding to the obstruction of small vessels by microdroplets of fat, originating from medulla ossium. Pulmonary involvement, present in 90% cases, makes the severity of the disease.

Case Report: We report the case of a 22-year-old man who presented, two days after industrial accident causing an opened tibial fracture, acute dyspnea with hemoptysis.
