Review Practice Guideline
[Management of angiotensin-converting enzyme inhibitor-related angioedema: recommendations from the French National Center for Angioedema].
Angiotensin-converting enzyme (ACE) inhibitor-related angioedema (AE) may be fatal in the absence of specific treatment. No consensus for this side effect currently exists. Also, the French national reference centre for angioedema (CREAK) decided to establish recommendations, developed by an expert group and proposed at a national meeting. ⋯ The subsequent use of ACE is strictly contra-indicated. A report to pharmacovigilance centres of every case is essential. These recommendations should improve the standardization of the management of ACE inhibitor-related AE.

Diffuse alveolar hemorrhage (DAH) is defined by the presence of red blood cells originating from the lung capillaries or venules within the alveoli. The diagnosis is established on clinical features, radiological pattern, and especially bronchoalveolar lavage. Diffuse alveolar hemorrhage may have many immune or non-immune causes. ⋯ Non-immune causes of DAH mainly include heart diseases, coagulation disorders, infections, drug toxicities and idiopathic DAH. Treatment of non-immune DAH is that of its cause. Whatever the cause, DAH is an emergency requiring prompt assessment and early treatment.

Review Case Reports
[An ANCA negative limited form of granulomatosis with polyangiitis (Wegener's granulomatosis) affecting the cavernous sinus].
Granulomatosis with polyangeitis (Wegener's granulomatosis) (GPA) is a granulomatous vasculitis associated with antineutrophil cytoplasmic antibodies (ANCA). Affected organs usually include upper and lower respiratory tracts, and kidneys. Limited forms of GPA may affect the central nervous system (vasculitis, hypertrophic pachymeningitis, encephalitis), a location in which diagnosis is often uneasy. ⋯ GPA presenting as a cavernous sinus syndrome is rare. Three co-existing pathogenic mechanisms may be involved in GPA affecting the central nervous system: contiguous invasion from nasal or orbitary granulomatous sites, vasculitis, or primary intra-cerebral granulomatous inflammation. Lack of biopsy evidence of affected tissues and ANCA negativity should not delay diagnosis and appropriate therapeutic management in central nervous system GPA.
