[Feasibility and practical value of statistical matching of a general practice database and a health insurance database applied to diabetes and hypertension].

Objectives: Public Health actors in France are striving to improve the use of national databases for public health and research. The main objective of this project was to develop a research tool in ambulatory care by matching medical data and reimbursement data.

Methods: Data sources were the health insurance database (SNIIRAM) and the General Practice Observatory (OMG) database.

Effect of biologic treatments on growth in children with juvenile idiopathic arthritis.

Objective: Growth retardation is a frequent complication of severe juvenile idiopathic arthritis (JIA). Biologic treatments may improve growth velocity by controlling systemic inflammation and reducing corticosteroids. Our goals were to compare growth velocity before and after the onset of biologic therapy and to determine whether the JIA subtype, the use of steroids, the requirement of one or several biologic agents, or the disease activity influenced growth velocity.

Invasive lobular carcinoma of the breast: MRI pathological correlation following bilateral total mastectomy.

Background: Invasive lobular carcinoma (ILC) is more often multifocal and bilateral than invasive ductal carcinoma. MRI is usually recommended for detection of all ILC sites. The performance of known diagnostic breast MRI criteria for ILC characterization has not been evaluated to date using bilateral mastectomy specimens as gold standard.
