ABSTRACT
PURPOSE OF REVIEW: The aim of this review is to provide an update of clinical presentation, diagnosis, differential diagnoses, and treatment according to recent evidence. RECENT FINDINGS: Neurosarcoidosis remains a diagnosis of exclusion, with infectious and malignant etiologies recognized as important mimickers. Corticosteroids remain as first-line therapy. In recent years, however, studies have demonstrated the effectiveness of anti-tumor necrosis factor (anti-TNF) therapy in the treatment of neurosarcoidosis, leading to improved outcomes. Neurosarcoidosis is a granulomatous disease with protean manifestations that may affect any part of the central and peripheral nervous system. It has many mimickers, and potentially devastating complications necessitating long-term follow-up. Early initiation of treatment, particularly with anti-TNF therapy, may lead to better outcomes and fewer relapses. There is an unmet need for randomized controlled trials that provide robust data to guide therapy and the long-term management of neurosarcoidosis patients.

Reduced symptomatology and access to testing in children have led to underestimates of paediatric COVID-19 prevalence and raised concerns about school safety. To explore COVID-19 prevalence and risk factors in school settings, we conducted a SARS-CoV-2 serosurvey in a Vermont, USA school district in December 2020. Among 336 students (63%) and 196 teachers/staff (37%), adjusted seroprevalence was 4.7% (95% CI 2.9 to 7.2) and was lowest in preK-5 students (4-10 Years). Seroprevalence was 10-fold higher than corresponding state PCR data but was low overall with no evidence of onward transmissions. These results further support feasibility of in-person learning during COVID-19 with appropriate mitigation measures.

There remains diagnostic uncertainty regarding the sensitivity of reverse transcription polymerase chain reaction in detection of SARS-CoV-2 from nasopharyngeal specimens. We present a case where two nasopharyngeal specimens were negative, followed by a positive sputum sample. Serial testing for COVID-19 is indicated in patients with high pretest probability of disease.
