Isolated Cervical Pain Revealing a Common Carotid Artery Dissection in a Child Following a Minor Trauma: A First Pediatric Case Report and a Review of the Literature.

BACKGROUND: Cervical artery dissections are not exceptional in the pediatric population. Typically, it affects the internal carotid artery or the vertebral artery. To our knowledge, this is the first case of common carotid artery (CCA) dissection in a child. CASE: We present a case of a 7-year-old-boy admitted to our neurology department complaining of cervical pain after a minor neck trauma. The neurological examination was normal. The ultrasound showed a mural hematoma with an intimal flap. The magnetic resonance angiography revealed an irregular segment of the left CCA just before its bifurcation. The diagnosis of an acute dissection on the left CCA was confirmed and antiplatelet therapy was started. CONCLUSION: The diagnosis of cervical artery dissections remains a challenge because of its variable clinical presentation. It should be suspected in the context of neck trauma and treatment should be initiated rapidly to reduce the risk of ischemic stroke.

Characteristics, onset, and evolution of neurological symptoms in patients with COVID-19.

BACKGROUND: A wide range of neurological manifestations has been described in COVID-19. METHODS: In this nationwide retrospective observational study, patients in Tunisia diagnosed with COVID-19 between the 2nd of March and the 16th of May 2020 were contacted by telephone. We collected demographic and clinical data and specified characteristics and evolution of main neurological symptoms. RESULTS: Of 1034 confirmed COVID-19 patients, 646 were included (mean age 42.17 years old) and 466 (72.1%) had neurological symptoms. Neurological symptoms were isolated 22.7% (n = 106). Headache was the most frequent neurological symptom (n = 279, 41.1%): mainly frontotemporal (n = 143, 51.1%) and mild or moderate (n = 165, 59.1%). When associated with fever (n = 143, 51.3%), headache was more likely to be severe and present at onset. Recovery was reported in 83.2%. Smell and taste impairment were found in 37.9% (n = 245) and 36.8% (n = 238) respectively. Among them, 65.3% (156/239) were anosmic and 63.2% (146/231) were ageusic. A complete improvement was found in 72.1% (174/240) of smell impairment and in 76.8% (179/233) of taste impairment. Myalgia (n = 241, 37.3%) and sleep disturbances (n = 241, 37.3%) were also frequent. Imported cases had more neurological symptoms (p = 0.001). In 14.5%, neurological symptoms preceded the respiratory signs (RS). RS were associated with more frequent (p = 0.006) and numerous (p < 0.001) neurological symptoms. CONCLUSIONS: Neurological symptoms in COVID-19 are frequent, can be isolated and present at onset. A total recovery is the most recorded outcome. RS are predictive of neurological symptoms. Studies in to virus and host genetics should be considered to understand the different phenotypes.
