Drug Rash with Eosinophilia and Systemic Symptoms (DRESS) syndrome is a drug-induced hypersensitivity syndrome, characterized by rash, hyereosinophilia and multiorgan failure, including cytolytic hepatitis. ⋯ Amoxicillin/clavulanic acid, although rarely described in the literature, is a rare cause of DRESS syndrome. Severe cholestatic hepatitis associated with disabling pruritus may be one of the systemic manifestations, with a good prognosis using corticosteroids and plasma exchanges.

Recent advances in neuroimaging have simplified the diagnostic criteria of multiple sclerosis. Indeed, the diagnosis of multiple sclerosis could be obtained during the first bout of disease flare, very early in the disease course. ⋯ At the same time, major therapeutic advances have been obtained and new drugs that are well tolerated and more effective, despite the possible rare but potentially severe side effects are been developed. This article reviews the modern diagnostic and therapeutic strategies in multiple sclerosis in accordance with the recent obtained advances.

Case Reports
[Macrophage activation syndrome as the presenting manifestation of intravascular lymphoma].
Intravascular large B cell lymphoma is a neoplastic cell proliferation leading to the occlusion of the lumen of small vessels. This is a rare haematological malignancy, which is difficult to diagnose because of a heterogeneous clinical presentation. ⋯ Due to the polymorphism and the systemic presentation of intravascular large B cell lymphoma, the internist may be confronted with this disease, which is considered to be more severe if associated with a macrophage activation syndrome. Awareness of the intravascular large B cell lymphoma is important because the prognosis depends on the rapidity of the initiation of chemotherapy associated with rituximab.

Most of recurrent pericarditis are idiopathic and only 15 to 20% have a specific diagnosis. Primary pericardial mesothelioma is a rare cause of recurrent pericarditis. Diagnosis can be challenging and antedates patient's death in only 10 to 20% of cases. Histology of mesothelioma and immunohistochemistry are mandatory for the diagnosis. Median of survival before using pemetrexed was about 6 months after diagnosis. ⋯ This case report highlights the necessity of repeat pericardial biopsy in the case of adverse outcome.

Aortitis is a serious complication of giant cell arteritis (GCA), because of the risk of aortic aneurism, rupture, or dissection. Aortitis is present either at presentation or, more frequently, occurs as a delayed complication, typically as an aortic aneurism of the ascending part of the aorta. An aortic aneurism may occur in up to 10% of patients. ⋯ When present at the time of diagnosis of GCA, these findings seem to be associated with frequent relapses and perhaps with a higher long-term vascular mortality rate. Therefore, we recommend the screening of aortitis lesions at GCA diagnosis by an aortic CT-scan and follow-up. Therapeutic trials should be conducted to try to improve the treatment of aortitis in GCA.
