RESUMEN
BACKGROUND: Neurofibromatosis type 1 (NF1) gives rise to a variety of spinal pathologies that include dural ectasia (DE), vertebral malalignments (VMA), spinal deformities (SD), syrinx, meningoceles, spinal nerve root tumours (SNRT), and spinal plexiform tumours (SPT). The relationship between these and the progression of these pathologies has not been explored before in detail and this paper aims to address this. METHODS: Data was retrospectively collected from adult NF1 multi-disciplinary team meetings from 2016 to 2022 involving a total of 593 patients with 20 distinct predictor variables. Data were analyzed utilizing; Chi-Square tests, binary logistic regression, and Kaplan-Meier analysis. RESULTS: SNRT (19.9%), SD (18.6%), and (17.7%) of VMA had the highest rates of progression. SD was significantly associated (p < 0.02) with the presence and progression of all spinal pathologies except for SPT. Statistically significant predictors of SD progression included the presence of DVA, VMA, syrinx, meningocele, and SNRT. Kaplan-Meier analysis revealed no statistically significant difference between the times to progression for SD (85 days), SNRT (1196 days), and VMA (2243 days). CONCLUSION: This paper explores for the first time in detail, the progression of various spinal pathologies in NF1. The presence and progression of SD is a key factor that correlated with the progression of different spinal pathologies. Early identification of SD may help support clinical decision-making and guide radiological follow-up protocols and treatment.

BACKGROUND: Spinal lesions are a known manifestation of neurofibromatosis type 1 (NF1). The aim of this retrospective review was to analyze and report the prevalence of spinal lesions on imaging in a large NF1 center. METHODS: The data were collected from a period of 62 months from a cohort of 514 patients. Data were collected from multidisciplinary team meeting reports that included radiologic reports of each patient investigating 20 distinct variables. The prevalence of each of these lesions was calculated, and any statistically significant associations were investigated using the χ2 test. RESULTS: Four-hundred forty-seven patients had classic NF1, and 67 patients had spinal NF1. Many of the patients had spinal abnormalities; 25.7% of these patients were found to have dural ectasia, whereas 44.9% of patients had a spinal deformity. A statistically significant association between dural ectasia and spinal neurofibromatosis was established (P < 0.05). An additional statically significant association was established between dural ectasia and spinal deformity (P < 0.00001). The patients with spinal nerve root tumors were identified, and it was found that 49.8% of patients possessed these tumors, whereas 56.3% of these tumors were intraspinal tumors. The most common region affected was the cervical spine, and the most common spinal level was C2. CONCLUSIONS: This high prevalence of spinal tumours in mobile areas of the spine is possibly the result of a combination of genetic predisposition and repeated microtraumas resulting in tumor formation. This is the largest reported study of spinal lesions in NF1 based on imaging and offers insights into the etiology and relationships between lesions.

The 2019 coronavirus disease (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been a pandemic in need of controlling. The disease has taken its toll on universities; as a consequence, universities must prepare their campuses in such a way that will reduce the spread of SARS-CoV-2 and COVID-19 and ensure the safety of their students. This is why it is necessary to critically assess the risks involved in reopening university campuses. This letter to the editor highlights the importance of the social side of student life on campus and how it might affect the precautions put in place to reduce SARS-CoV-2 transmission. Furthermore, this letter is proposing potential courses of action for universities to take during the pandemic for the forthcoming academic year. The ability of universities to contain the spread of the virus is limited, as they lack control over social interactions outside of campus. We discuss the multifaceted approach needed to educate students about off-campus transmission to prevent SARS-CoV-2 transmission.
