Orbital lesion (pseudotumor and dacryoadenitis) is a manifestation of systemic sarcoidosis

E.A.&nbsp;Burylova, L.A.&nbsp;Mamaeva, A.S.&nbsp;Berdnikova, O.K.&nbsp;Fedorova Ural Scientific Research Institute of Phtysiopulmonology — Branch of the National Medical Research Center of Phtysiopulmonology, Yekaterinburg, Russian Federation Abstract Ocular manifestations of systemic sarcoidosis may emerge at any disease stage. Ocular sarcoidosis is typically characterized by uveitic presentations that predominantly involve the choroid of anterior eye segment. However, orbital pseudotumor, dacryoadenitis, and other rare presentations (optic neuritis, dacryocystitis etc.) also occur in sarcoidosis. Threatened vision loss and poor quality of life are the reasons to prescribe systemic steroids in generalized sarcoidosis. Chest CT is required to identify respiratory diseases when sarcoidosis manifests as uveitis or granulomatous orbital inflammation. Multidisciplinary diagnostic and treatment approach to suspected sarcoidosis provides timely verified diagnosis and management strategy. This paper addresses case report of systemic sarcoidosis in a 34-year-old man. The initial manifestation was vision loss and left orbital pseudotumor. The enlarged subclavian lymph node and its biopsy were suspicious of granulomatous inflammation. Chest CT identified disseminated pulmonary lesions and intrathoracic lymphadenopathy that are typical of sarcoidosis. The results of multidisciplinary examina tions verified systemic sarcoidosis. Systemic steroids resulted in clinical and radiological improvement and medicinal regression of the disease.

CMS physics technical design report: Addendum on high density QCD with heavy ions

This report presents the capabilities of the CMS experiment to explore the rich heavy-ion physics programme offered by the CERN Large Hadron Collider (LHC). The collisions of lead nuclei at energies ,will probe quark and gluon matter at unprecedented values of energy density. The prime goal of this research is to study the fundamental theory of the strong interaction - Quantum Chromodynamics (QCD) - in extreme conditions of temperature, density and parton momentum fraction (low-x). This report covers in detail the potential of CMS to carry out a series of representative Pb-Pb measurements. These include "bulk" observables, (charged hadron multiplicity, low pT inclusive hadron identified spectra and elliptic flow) which provide information on the collective properties of the system, as well as perturbative probes such as quarkonia, heavy-quarks, jets and high pT hadrons which yield "tomographic" information of the hottest and densest phases of the reaction.0info:eu-repo/semantics/publishe
