Purpose of review Early access to rheumatology is imperative to achieve appropriate outcomes in rheumatologic diseases. But there seems to be a significant gap and disparity in the access to rheumatology care between urban and rural areas. This review was undertaken to analyze this issue. Recent findings A significant delay in diagnosis of rheumatic disorder has been correlated to the travel distance to rheumatologist. It is also clear that currently, a significant rheumatology workforce shortage exists and is projected to worsen significantly, thereby making this gap and disparity much bigger. Summary The scope of this gap and disparity in rheumatology care for rural patients remains incompletely defined and quantified. It is felt to be a significant issue and it is important to invest resources to obtain information about its scope. In addition, a number of solutions already exist which can be implemented using current network and infrastructure. These include relatively low-cost interventions such as patient navigator, remote rheumatology experts and if possible tele-rheumatology. These interventions can assist temporarily but a major improvement will require policy change at federal and state government level as well as involvement, buy-in, and incentivization of the providers and health networks providing rheumatology care.

Neuromyelitis optica (NMO) and neuromyelitis optica spectrum disorders (NMOSD), previously known as Devic's syndrome, are a group of inflammatory disorders of the central nervous system (CNS) characterized by severe, immune-mediated demyelination and axonal damage, predominantly targeting optic nerves and the spinal cord typically associated with a disease-specific serum NMO-IgG antibody that selectively binds aquaporin-4 (AQP4). The classic and best-defined features of NMOSD include acute attacks of bilateral or rapidly sequential optic neuritis (leading to visual loss) or transverse myelitis (often causing limb weakness and bladder dysfunction) or both with a typically relapsing course. The diagnosis of NMO/NMOSD requires a consistent history and examination with typical clinical presentations, findings on spinal cord neuroimaging with MRI, cerebrospinal fluid analysis along with determination of AQP4-IgG serum autoantibody status, and exclusion of other disorders. Two major advances in this field has been the development of diagnostic criteria and treatment recommendations. Consensus diagnostic criteria have been established and were recently revised and published in 2015, enhancing the ability to make a diagnosis and appropriately evaluate these disorders. Expert recommendations and uncontrolled trials form the basis of treatment guidelines. All patients with suspected NMOSD should be treated for acute attacks as soon as possible with high-dose intravenous methylprednisolone -1 gram daily for three to five consecutive days and in some cases, plasma exchange should be used. It is recommended that every patient with NMOSD be started on an immunosuppressive agent, such as, azathioprine, methotrexate, or mycophenolate and in some cases, rituximab, soon after the acute attack and usually be treated for about 5 years after the attack. These advances have helped improve the prognosis and outcome in these disorders.
