Familial Mediterranean fever (FMF) is characterized by recurrent episodes of fever accompanied by serosal, synovial, or cutaneous inflammation. The central nervous system (CNS) is rarely involved in FMF. The CNS involvement includes demyelinating lesions, posterior reversible encephalopathy syndrome, pseudotumor cerebri, optic neuritis, and cerebral vasculitis. Here, we present a 20-year-old man, a known case of FMF with abrupt left-sided hemiparesis. Brain magnetic resonance imaging revealed right periventricular infarction...

Neuromyelitis optic spectrum disorders are demyelinating conditions that are typically idiopathic, though various case reports have demonstrated an association with malignancy. We present the case of a 64year old woman with NMOSD in the setting of small cell lung cancer. She had longitudinally extensive transverse myelitis and left eye optic neuritis; aquaporin-4 antibodies were elevated. Biopsy of mediastinal adenopathy was positive for SCLC. Malignancy should be considered in any patient with an atypical presentation of NMOSD, or who does not respond to traditional therapies...

We collected serum-cerebrospinal fluid (CSF)-paired samples during the acute phase of clinical episodes in MS and NMO patients, together with paired samples from non-MS/NMO patients, to compare the quotients of proteins and electrolytes among them. In NMO, the quotient of chloride was significantly higher in the acute phase of optic neuritis and brain lesions, but it was significantly lower in the acute phase of myelitis. Such findings were not observed in MS or in non-MS/NMO cases. With the coexistence of serum anti-AQP4-Ab, chloride imbalance between serum and CSF could be associated with the clinical episodes in NMO...

The classical presentation of secondary syphilis comprises skin rashes, mucosal ulceration and lymphadenopathy. However, this disseminated stage can also present with symptoms and signs of ocular, neurological, pulmonary, renal, musculoskeletal and digestive tract disease. We report the case of a gay man who presented with icteric hepatitis. Although he underwent an exhaustive series of investigations (some of which were invasive), syphilis was not initially considered in the differential diagnosis. His jaundice resolved spontaneously, but he subsequently developed an acute optic neuritis...

Evoked potentials are time-locked electrophysiologic potentials recorded in response to standardized stimuli using scalp electrodes. These responses provide good temporal resolution and have been used in various clinical and intraoperative settings. Olfactory evoked potentials (OEPs) may be used as an adjunct tool in identifying patients of Parkinson disease and Alzheimer dementia. In clinical practice, visual evoked potentials (VEPs) are particularly useful in identifying subclinical cases of optic neuritis and in treatment surveillance...

Importance: Clinical outcome in multiple sclerosis was suggested to be driven by not only remyelination but also adaptive reorganization. This mechanism needs to be further understood. Objective: To explore anatomical and functional visual networks in patients with optic neuritis (ON) to assess the relative weight of each connectivity modality to expedite visual recovery. Design, Setting, and Participants: Between March 11, 2011, and May 26, 2014, 39 patients with either clinically isolated syndrome (CIS) ON (n = 18) or other CIS (non-ON) (n = 21) were recruited 1 to 28 months following an initial clinical event...

Oxidative stress plays a critical role in the pathogenesis of retinal degeneration. Gypenosides are the major functional components isolated from Gynostemma pentaphyllum. They have been shown to protect against oxidative stress and inflammation and have also demonstrated a protective effect on experimental optic neuritis. In order to determine the protective properties of gypenosides against oxidative stress in human retinal pigment epithelium (RPE) cells, ARPE-19 cells were treated with H2O2 or H2O2 plus gypenosides for 24 h...
