An Unusual Case of an Intradiploic Arachnoid Cyst of the Orbit.

This study reported a case of an arachnoid cyst of the sphenoid bone causing orbital signs and symptoms in a 58-year-old man with progressive proptosis and nonspecific discomfort in the OS. Orbital MRI showed a 3-cm homogeneous cyst within the left greater wing of the sphenoid bone. To the best of our knowledge, this is the first report of an intradiploic arachnoid cyst in the sphenoid bone with atypical radiological features, causing clinical symptoms, and managed through an eyelid approach, achieving a complete resolution with no complications.

Understanding Visual Disorders through Correlation of Clinical and Radiologic Findings.

Patients presenting with visual disturbances often require a neuroimaging approach. The spectrum of visual disturbances includes three main categories: vision impairment, ocular motility dysfunction, and abnormal pupillary response. Decreased vision is usually due to an eye abnormality.

Tumefactive inflammatory leukoencephalopathy in cocaine users: Report of three cases.

Background: Cocaine is the most common illicit stimulant drug used in Europe, and it can potentially affect the central nervous system due to a direct effect, or by means of additive drugs. Levamisole has been increasingly used as an additive drug since it extends the stimulating effects of cocaine. This has led to an increase in the detection of levamisole adverse reactions, including levamisole-induced multifocal inflammatory leukoencephalopathy (MIL), a potentially lethal monophasic cerebral demyelinating disease.

Measurements of signal intensity of globus pallidus and dentate nucleus suggest different deposition characteristics of macrocyclic GBCAs in children.

Introduction: The safety of using GBCAs to enhance the visibility of body structures is currently discussed due to possible gadolinium retention in brain structures. The aim of the study was to evaluate the effect of multiple exposures to macrocyclic GBCAs in children.

Materials And Methods: This retrospective, single-center study included data from 43 patients who had received ≥4 injections of macrocyclic GBCAs during MRI examinations over performed over 8 to 84 months.

The use of rifaximin in pre-operative period of patients with tumors of the gastrointestinal tract - a retrospective study (2013-2016).

Unlabelled: ntroduction: One of the most important goals of preparing a patient for elective gastrointestinal cancer surgery is prevention of postoperative complications. The literature gives many ways to prepare for surgery, but only a few suggests that pre-operative use of rifaximin provides benefits in the form of fewer perioperative complications and reduces the severity of pain during this period. O bjective: The presented project is a retrospective analysis of the effectiveness of rifaximin in the prevention of perioperative complications in patients treated in the Unit of General Surgery with the Orthopedic and Urology in the Hospital of the Ministry of the Interior and Administration in Lublin, and a review of international literature in this subject.

[The role of Th17 cells in anti-cancer immunity].

Th17 cells are a newly identified population of CD4+ Th cells characterized by interleukin 17 production and are therefore named "Th17". Interleukin 17 (IL-17; IL-17A) is one of the key cytokines for the activation, recruitment, and migration of neutrophils, so Th17 cells have been suggested to play an important role in responses against extracellular bacteria and fungi, in which granulocyte infiltration is highly protective. Among the other cytokines secreted by Th17 cells are IL-22, IL-26, IL-6, and TNF-a.
