The knowledge of systemic necrotizing vasculitides improved since new classifications have been established along with a better understanding of pathogenesis of the diseases. The major vasculitides are described herein. ⋯ Despite the good results obtained with and demonstrated in prospective trials, the vasculitides remain severe and deserve new studies testing new drugs but also strategies based on prognostic factors and scores which should play a major role in treatments decision.

Sleep-wake rhythm disturbances observed in Alzheimer's disease are correlated with the severity of cognitive impairment and often result in institutionalization. These disturbances are also a major cause of psychotropic medication misuse. We report age-related physiologic and disease related pathologic changes in sleep-wake rhythms and propose chronobiological treatment approaches in patients with Alzheimer's disease. ⋯ In Alzheimer patients, controlling sleep-wake disturbances with sedative drugs often increases both sleep disturbance and cognitive dysfunction. A chronobiological approach with bright-light therapy, melatonin administration, restricted time in bed, and diurnal activity may be an interesting therapeutic alternative in the management of sleep-wake disorders in Alzheimer patients. The aim of these therapeutics is to improve sleep and diurnal activity and consequently to increase the quality of life in Alzheimer patients.

Cutaneous metastatic Crohn's disease is a granulomatous inflammation of the skin that is noncontiguous to the gastrointestinal tract. ⋯ During Crohn's disease, biopsy should be considered for every undiagnosed skin lesion as the characteristics of cutaneous metastatic Crohn's disease are not specific. The presence of a non caseous granulomatous dermal infiltration suggests the diagnosis and should make consider the initiation of corticosteroid and the discontinuation of others inappropriate therapeutics (i.e. surgical treatment, antibiotics).

The aim of the study was to assess the place of cardiac Magnetic Resonance Imaging (MRI) in patients with sarcoidosis with or without cardiac involvement. ⋯ Cardiac MRI is a useful non-invasive method for the early diagnosis and follow-up of cardiac sarcoidosis.
