The concept of IgG4-related disease (IgG4-RD) has recently been individualized in the early 2000s, but most of the organ involvements are known since more than 100 years. IgG4-RD is a non-malignant fibroinflammatory disorder, characterized by peculiar immunological and pathological abnormalities, which can affect virtually all organs or tissues. ⋯ The objective of this review is to discuss the evolution from organ specific and general diagnostic criteria toward the 2019 ACR/EULAR classification criteria, as well as respective benefits and limits of these criteria. The use of the 2019 ACR/EULAR classification criteria will help to better define homogeneous group of IgG4-RD patients in future clinical, epidemiological and basic science research studies on the disease.

Thrombotic thrombocytopenic purpura (TTP) is a devastating disease characterized by disseminated microvascular thrombosis. Despite pro-thrombotic predisposing conditions, the prevalence of macrovascular venous thrombosis event (VTE) in immune-mediated TTP (iTTP) has rarely been assessed. ⋯ VTE is a frequent condition occurring during iTTP management and is observed when patients require a prolonged treatment with daily TPE and multiple catheter insertions. Therapeutic strategies aimed at reducing the duration of TPE treatment in iTTP should substantially reduce this complication.

Review Case Reports
[Pituitary apoplexy following coronary bypass surgery: A case report and literature review].
Pituitary apoplexy is a >rare entity that presents with a sudden onset of headache associated with visual and endocrinological disturbances due to pituitary hemorrhage or infarction. It usually occurs in patients with an unknown pituitary adenoma. Cardiac surgery, and especially coronary artery bypass grafting, can be a precipitating factor in these patients. ⋯ Pituitary apoplexy is a rare and life-threatening complication that may occur after cardiac surgery (coronary artery bypass, cardiac valve surgery), often precipitated by the use of cardiopulmonary bypass. It can occur after other surgical procedures (orthopedic, digestive, thoracic). The diagnosis must be considered during the early postoperative period in the presence of unusual and severe headache associated with visual disturbances.

To describe a case series of patients investigated in internal medicine for orbital inflammation (OI) since the individualization of the clinical entity of the IgG4-related orbital disease (IgG4 ROD). ⋯ After ruling out auto-immune orbital diseases, especially IgG4 ROD, IOIS should be discussed. Factors conditioning the corticosteroid response are yet to be determined.
