ABSTRACT

Lyme neuroborreliosis (LNB) is a tick-borne infection caused by Borrelia burgdorferi which can affect the nervous system in adults and children. The clinical course of LNB in adults is often different than in children. Studies comparing these differences are scarce. The aim of this study was to compare the clinical characteristics and outcome of LNB between children and adults. We performed an observational retrospective study among patients with LNB who presented at Gelre Hospital from 2007 to 2020 and had cerebrospinal fluid pleocytosis. Data were collected from electronic medical records. A total of 127 patients with LNB were identified. Included were 58 children (median age 8 years) and 69 adults (median age 56 years). The incidence of LNB was 3.2 per 100,000 inhabitants per year. The most common neurological manifestation in adults and in children was facial nerve palsy (67%). Unilateral facial nerve palsy was more prevalent in children (85%) than in adults (42%) (P < 0.001). Headache was also more prevalent in children (59%) than in adults (32%) (P = 0.003). (Poly)radiculitis was more prevalent in adults (51%) than in children (3%) (P < 0.001), encephalitis was not reported in children. In children, the time between symptom onset and diagnosis was 10 days versus 28 days in adults (P < 0.001). Complete recovery was reported significantly more often in children (83%) compared to adults (40%) (P < 0.001).    Conclusion: In a Lyme-endemic area in the Netherlands, LNB commonly presents with facial nerve palsy. Facial nerve palsy and headache are more prevalent in children, while radiculitis and encephalitis are mostly reported in adults. What is Known: • The clinical course of Lyme neuroborreliosis in adults is often different from children. . • The aim of this study was to compare the clinical characteristics and outcome of LNB between children and adults. What is New: • Lyme neuroborreliosis in the Netherlands commonly presents with facial nerve palsy. • Facial nerve palsy and headache are more prevalent in children than in adults. Radiculitis and encephalitis are mostly reported in adults.

ABSTRACT

BACKGROUND: High von Willebrand factor (VWF) plasma levels are associated with an increased risk of stroke. VWF levels are strongly heritable. A previous meta-analysis of five large genome-wide association studies identified single-nucleotide polymorphisms (SNPs) within eight genetic loci as determinants of VWF levels. Whether these SNPs are associated with stroke risk is not known. The aim of our study was to investigate the association between genetic determinants of VWF levels and stroke risk. METHODS: The study was part of the Rotterdam Study, a large population-based cohort study among subjects aged ≥ 55 years. A total of 5763 participants for whom DNA was available, and who were free of stroke at baseline, were eligible for analysis. VWF antigen (VWF:Ag) levels were measured in 3379 eligible participants. Within each of the eight loci, one top SNP was defined. The association between the eight SNPs and the risk of stroke was analyzed. Then, a genetic score, based on these eight SNPs, was constructed, and its total contribution to VWF plasma levels and stroke risk was investigated. RESULTS: None of the eight SNPs was individually associated with stroke risk. A higher genetic score was significantly associated with a higher VWF:Ag level, but was not associated with an increased risk of stroke. CONCLUSION: Eight SNPs that strongly determine VWF levels are not associated with stroke risk, either individually, or combined in a genetic score.

ABSTRACT

BACKGROUND AND PURPOSE: We describe a left-handed patient with transient aphasia and bilateral carotid stenosis. Computed tomography (CT) arteriography showed a 90% stenosis of the right and 30% stenosis of the left internal carotid artery. Head CT and magnetic resonance imaging (MRI) of the brain showed no recent ischemic changes. As only the symptomatic side would require surgical intervention, and because hemispheric dominance for language in left-handed patients may be either left or right sided, a preoperative assessment of hemispheric dominance was required. METHODS: We used functional MRI to determine hemispheric dominance for language and hence to establish the indication for carotid endarterectomy surgery. RESULTS: Functional MRI demonstrated right hemispheric dominance for language and right-sided carotid endarterectomy was performed. CONCLUSIONS: We propose that the clinical use of functional MRI as a noninvasive imaging technique for the assessment of hemispheric language dominance may be extended to the assessment of hemispheric language dominance prior to carotid endarterectomy.
