TL;DR: The acquisition of a T674I resistance mutation at the time of relapse demonstrates that FIP1L1-PDGFRalpha is the target of imatinib, and data indicate that the deletion of genetic material may result in gain-of-function fusion proteins.
Abstract: Background Idiopathic hypereosinophilic syndrome involves a prolonged state of eosinophilia associated with organ dysfunction. It is of unknown cause. Recent reports of responses to imatinib in patients with the syndrome suggested that an activated kinase such as ABL, platelet-derived growth factor receptor (PDGFR), or KIT, all of which are inhibited by imatinib, might be the cause. Methods We treated 11 patients with the hypereosinophilic syndrome with imatinib and identified the molecular basis for the response. Results Nine of the 11 patients treated with imatinib had responses lasting more than three months in which the eosinophil count returned to normal. One such patient had a complex chromosomal abnormality, leading to the identification of a fusion of the Fip1-like 1 (FIP1L1) gene to the PDGFRα (PDGFRA) gene generated by an interstitial deletion on chromosome 4q12. FIP1L1-PDGFRα is a constitutively activated tyrosine kinase that transforms hematopoietic cells and is inhibited by imatinib (50 perce...

TL;DR: As the diagnosis of AP is most often established by clinical symptoms and laboratory testing, contrast-enhanced computed tomography and/or magnetic resonance imaging of the pancreas should be reserved for patients in whom the diagnosis is unclear or who fail to improve clinically.

TL;DR: The Global Burden of Disease, Injuries, and Risk Factor study 2013 (GBD 2013) as mentioned in this paper provides a timely opportunity to update the comparative risk assessment with new data for exposure, relative risks, and evidence on the appropriate counterfactual risk distribution.

TL;DR: Clinical, laboratory, and imaging features generally distinguish neuromyelitis optica from MS, and patients with relapsing optic neuritis and myelitis may have neuromyeliitis opticas rather than MS.
Abstract: Objectives: To evaluate the spectrum of neuromyelitis optica (NMO), including characteristics of the index events (optic neuritis [ON]) and myelitis), neuroimaging, CSF, and serologic studies, and to evaluate the long-term course. Methods: Review of 71 patients with NMO evaluated at the Mayo Clinic between 1950 and 1997. Results: NMO was either monophasic or relapsing. Patients with a monophasic course (n = 23) usually presented with rapidly sequential index events (median 5 days) with moderate recovery. Most with a relapsing course (n = 48) had an extended interval between index events (median 166 days) followed within 3 years by clusters of severe relapses isolated to the optic nerves and spinal cord. Most relapsing patients developed severe disability in a stepwise manner, and one-third died because of respiratory failure. Features of NMO distinct from “typical” MS included >50 cells/mm 3 in CSF (often polymorphonuclear), normal initial brain MRI, and lesions extending over three or more vertebral segments on spinal cord MRI. Conclusions: Clinical, laboratory, and imaging features generally distinguish neuromyelitis optica from MS. Patients with relapsing optic neuritis and myelitis may have neuromyelitis optica rather than MS. Patients with a relapsing course of neuromyelitis optica have a poor prognosis and frequently develop respiratory failure during attacks of cervical myelitis.
