Rare case of cryptogenic brain abscess caused by Raoultella ornithinolityca

World Journal of Clinical Cases 2017年第7期5卷 299-302页

作者： marianna luongo Department of Neurosurgery San Carlo Hospital

Cerebral abscess is a potentially fatal neurosurgical condition,despite improvements in technology,new antimicrobial agents and modern neurosurgical instruments and techniques.I report the case of a 64-yearold woman,affected by a right frontobasal brain abscess,compressing the homolateral frontal horn of lateral ventricle,with a second mass partially occupying the right orbital *** presented also with inflammatory sinusopathy involving the right maxillary,ethmoid and frontal *** 14 d of clinical observation and antimicrobial therapy,the patient received a computed tomography scan,which showed growth of the cerebral mass,with a ring of peripheral contrast enhancement and surrounding *** promptly underwent neurosurgical treatment and recovered well,except for the sight in her right eye,which remained compromised,as before the *** is believed to be the first case of cryptogenic cerebral abscess caused by Raoultella ornithinolityca isolated from the brain,with more than 1-year follow-up.

Poorly differentiated gastric neuroendocrine carcinomas, although rare, deserve particular attention, as they are aggressive and have an extremely poor prognosis. In this report we describe a gastric neuroendocrine carcinoma with rapidly fatal outcome. Immunohistological staining of the resected specimens revealed that the tumor was an endocrine carcinoma. The tumor disclosed intense immunoreactivity to pan-neuroendocrine markers and diffuse somatostatin immunoreactivity. There were no psammoma bodies and no demonstrable association with yon Recklinghausen＇s neurofibromatosis. In the gastrointestinal tract, neuroendocrine tumors producing predominantly somatostatin have been described only in the duodenum. To the best of our knowledge, the present report is the second case report of a neuroendocrine gastric carcinoma expressing diffusely somatostatin as the only neuroendocrine regulatory peptide.

The identification of jets originating from quarks and gluons,often referred to as quark/gluon tagging,plays an important role in various analyses performed at the Large Hadron Collider,as Standard Model measurements and searches for new particles decaying to quarks often rely on suppressing a large gluon-induced *** paper describes the measurement of the efficiencies of quark/gluon taggers developed within the ATLAS Collaboration,using √s=13 TeV proton–proton collision data with an integrated luminosity of 140 fb^(-1) collected by the ATLAS *** taggers with high performances in rejecting jets from gluon over jets from quarks are studied:one tagger is based on requirements on the number of inner-detector tracks associated with the jet,and the other combines several jet substructure observables using a boosted decision tree.A method is established to determine the quark/gluon fraction in data,by using quark/gluon-enriched subsamples defined by the jet *** in tagging efficiency between data and simulation are provided for jets with transverse momentum between 500 GeV and 2 TeV and for multiple tagger working points.
