A first search for the Ξ_(bc)^(+)J/ψΞ_(c)^(+) decay is performed by the LHCb experiment with a data sample of proton-proton collisions, corresponding to an integrated luminosity of 9 fb−1 recorded at centre-of-mass energies of 7, 8, and 13 TeV. Two peaking structures are seen with a local (global) significance of 4.3(2.8) and 4.1(2.4) standard deviations at masses of 6571 and 6694 meV/c2, respectively. Upper limits are set on the Ξ+bc baryon production cross-section times the branching fraction relative to that of the B+c→J/ψD+s decay at centre-of-mass energies of 8 and 13 TeV, in the Ξ+bc and in the B+c rapidity and transverse-momentum ranges from 2.0 to 4.5 and 0 to 20GeV/c, respectively. Upper limits are presented as a function of the Ξ+bc mass and lifetime.

Cerebral Localization of Chronic Lymphocytic Leukemia Simulating Progressive multifocal Leukoencephalopathy: The Lessons from a Case

Case Reports in Clinical medicine 2020年第4期9卷 96-106页

作者： T. m. Sandouno S. Chebrek C. Tchonko G. Pichancourt L. Giovannetti H. Zerazhi Romain Appay H. Lepidi H. Bachir S. Hamaz H. B. Alaoui K. Serraj B.

Background: Central neurological involvement is the most frequent extra hematological manifestation of chronic lymphocytic leukemia;it is multifactorial and rarely due to a cerebral localization of the disease. We report a case of cerebral localization of chronic lymphoid leukemia whose clinical and radiological aspects were very suggestive of progressive multifocal leukoencephalopathy. Case Presentation: A 65-year-old patient who was HIV-negative (human immunodeficiency virus), had consulted for bilateral axillary, cervical and inguinal lymphadenopathy associated with major asthenia and hyper lymphocytosis (lymphocyte count was 11 giga/l). Chronic lymphocyticleukemia with TP53 mutation was diagnosed and trea.m.nt with Ibrutinib 420 mg/day was initiated. After 2 months of trea.m.nt, the evolution was marked by the onset of neurological disorders whose clinical-radiological presentation and temporal evolution had led to the diagnosis of progressive multifocal leukoencephalopathy. In the absence of virological evidence in the cerebrospinal fluid analysis, a stereotactic biopsy of the brain lesions had been performed, making it possible to formally rule out this infectious hypothesis and to demonstrate cerebral invasion by tumour cells. Immuno-chemotherapy combining Rituximab-Cyclophosphamide-Doxorubicin-Vincristine-Prednisone-Ibrutinib (RCHOP-Ibrutinib) with intrathecal chemotherapy resulted in a very good clinical-radiological response. Conclusion: The appearance of neurological manifestations in the context of chronic lymphocytic leukemia.m.st systematically lead to a search for a cerebral localization of the disease. In the absence of virological evidence in the cerebrospinal fluid, any suspicion of progressive multifocal leukoencephalopathy in this context should lead to the histological study of brain lesions.
