[The hepatopulmonary syndrome].

Definition: The hepatopulmonary syndrome (HPS) associates a chronic hepatic affection, hypoxemia < 70 mm Hg and pulmonary vasodilatation.

Physiopathology: The mechanisms leading to pulmonary vasodilatation are complex and unclear. There appears to be an imbalance between the vasodilatating and vasoconstricting mediators.

[Lemierre syndrome: clinical and radiological characteristics of a rare disease].

A benign oropharyngial infection without appropriate treatment can be complicated by a jugular vein thrombosis and disseminated septic embolies with deleterious pulmonary effects. This septic clinical picture most commonly known as Lemierre syndrome is attributed to Fusobacterium necrophorum, a Gram negative anaerobic bacilli. We describe a case of a young patient who has presented this syndrome accompanied by typical pulmonary manifestations.

Reduced cardiac sympathetic autonomic tone after long-term nasal continuous positive airway pressure in obstructive sleep apnoea syndrome.

The increased sympathetic activation that occurs in obstructive sleep apnoea (OSA) may play an important role in associated morbidity. We investigated the effect of long-term (3 month) nasal continuous positive airway pressure (CPAP) on the autonomic nervous system assessed by heart rate variability (HRV). Fourteen patients (12 men), mean age 61.

[An unusual cause of aorto-bronchial fistula: tuberculosis aortitis].

The aortic rupture in the pulmonary parenchyma or the bronchi rarely results in an haemoptysis. It means in most of the cases the rupture of an aortica aneurysm. We relate the observation of a aorto-bronchial fistula from a tuberculosa origin in an old woman case.

Bronchial carcinoids. A review of 22 cases.

This study investigated 22 patients with histologically proven primary bronchial carcinoids and in particular the relationship between assessment parameters and survival. In each patient, age, sex, smoking habits, mode of presentation, results of diagnostic investigations, methods of treatment and pathological examination of resected specimens were recorded. Follow-up was possible in all patients for at least 5 years.
