ABSTRACT

BACKGROUND: Medulloblastomas are the most common malignant brain tumors in the pediatric population. Based on the idea that tumors with identical radio-genomic features should behave similarly, the 4 molecular subtypes are now widely accepted as a guide for the management and prognosis. The radiological features of medulloblastomas can predict the molecular subtype; thus, anticipating the subsequent disease progression. However, this has not been evaluated comprehensively. We aim to thoroughly study the association between the molecular subtypes and radiological features of medulloblastomas. Moreover, we aim to investigate the efficacy of this correlation with the use of progression-free survival and 5-year survival rates. METHODS: A retrospective analysis was conducted for all histopathological confirmed medulloblastomas in pediatric patients (<16 years old) that were operated on in Kuwait over the past ten years (n = 44). The radiological, histological, and molecular characteristics were justifiably evaluated and analyzed in our sample. RESULTS: The overall progression-free survival after one year was noticed among 27 cases (≈44%) and the nonspecific 5-year survival was seen in 31 cases (≈70%) after a 5-year follow-up. Sonic Hedgehog and Wingless had the best outcomes, while group 3 showed the worst outcomes. CONCLUSIONS: Our findings did not support the association between most of the typical magnetic resonance imaging characteristics and survival rate. We further established that Sonic Hedgehog and Wingless biological types have a better prognosis. There was no association observed between the radiographic features, specifically the location, and the molecular subtype.

ABSTRACT

BACKGROUND: The novel coronavirus disease (COVID-19) is a life-threatening illness, which represents a challenge to all health care workers. Neurosurgeons worldwide are affected in different ways. OBJECTIVE: This is the first study regarding the readiness of neurosurgery residents for the COVID-19 pandemic and its impact. The aim is to identify the level of knowledge and readiness and the impact of this virus among neurosurgery residents in different programs. METHODS: A cross-sectional analysis was performed in which 52 neurosurgery residents from different centers were selected to complete a questionnaire-based survey. The questionnaire comprised 3 sections and 27 questions that ranged from knowledge to impact of the pandemic on various features. RESULTS: The median knowledge score was 4 out of 5. The proportion of participants with a satisfactory level of knowledge was 60%. There was a statistically significant difference between the knowledge score and location of the program. Around 48% of the neurosurgery residents dealt directly with patients with COVID-19. Receiving a session about personal protective equipment was reported by 57.7%. Neurosurgery training at the hospital was affected. About 90% believed that this pandemic had influenced their mental health. CONCLUSIONS: Neurosurgery residents have a relatively good knowledge about COVID-19. The location of the program was associated with knowledge level. Most participants did not receive sufficient training about personal protective equipment. Almost all responders agreed that their training at the hospital had been affected. Further studies are needed to study the impact of this pandemic on neurosurgery residents.
