Corneal Confocal Microscopy in the Diagnosis of Small Fiber Neuropathy: Faster, Easier, and More Efficient Than Skin Biopsy?

Pathophysiology 2021 Dec 26;29(1):1-8. Epub 2021 Dec 26.

Laboratory Mosaic Autoimmunity, St. Petersburg State University, 199304 St. Petersburg, Russia.

Chronic pain may affect 30-50% of the world's population and an important cause is small fiber neuropathy (SFN). Recent research suggests that autoimmune diseases may be one of the most common causes of small nerve fiber damage. There is low awareness of SFN among patients and clinicians and it is difficult to diagnose as routine electrophysiological methods only detect large fiber abnormalities, and specialized small fiber tests, like skin biopsy and quantitative sensory testing, are not routinely available.

A Rare Case of Steroid-Resistant Neurosarcoidosis of the Cavernous Sinus With Optic Neuropathy: A Case Report.

Neurohospitalist 2021 Oct 8;11(4):356-359. Epub 2021 Feb 8.

Department of Internal Medicine, John H. Stroger, Jr. Hospital of Cook County, Chicago, IL, USA.

Sarcoidosis is an inflammatory disease that presents with nervous system involvement in 5-10% of cases, commonly known as neurosarcoidosis. While there are no randomized controlled trials for the treatment of neurosarcoidosis, expert opinion supports initial treatment with corticosteroids and the use of steroid-sparing or anti-TNF agents in refractory or severe cases. We report a case of a 48-year-old African American male with a past medical history of biopsy-proven hepatic and renal sarcoidosis and progressive headache, dizziness, and blurry vision for 5 months, presenting with an acute exacerbation of right-sided vision loss over one day.
