ABSTRACT

AIM: We reviewed the clinical features of a sample of pediatric acquired demyelinating syndromes with the purpose of determining the appropriate protocol for follow-up after the first episode. METHODS: A multicenter retrospective observational study was conducted on a cohort of 40 children diagnosed with a first episode of acquired demyelinating syndrome over the period 2012-2021. Patients were evaluated with clinical and neuroradiologic assessment after 3, 6, and 12 months, with a median follow-up of 4.0 years. RESULTS: At the first acquired demyelinating syndrome episode, 18 patients (45%) were diagnosed with acute disseminated encephalomyelitis, 18 (45%) with clinical isolated syndrome, and 4 (10%) with multiple sclerosis. By month 12, 12 patients (30%) had progressed from an initial diagnosis of acute disseminated encephalomyelitis (2) or clinical isolated syndrome (10) to multiple sclerosis. Of these, 6 had clinical relapse and 6 radiologic relapse only. The first relapse occurred after a median of 3 months. Among the patients who had evolved toward multiple sclerosis, there was a prevalence of females (P = .014), higher oligoclonal bands positivity (P = .009), and older median age (P < .001) as compared with those who had remained stable. INTERPRETATION: Both clinical and radiologic follow-up of children with acquired demyelinating syndromes is crucial, especially during the first year after acute onset, for early identification of multiple sclerosis and prompt initiation of disease-modifying treatment to delay axonal damage and to limit disability.

ABSTRACT

OBJECTIVES: We summarized the clinical and radiological characteristics of meningitis-retention syndrome (MRS), its therapeutic options, and urological outcome, to better understand the pathogenesis of this syndrome and to evaluate the effectiveness of corticosteroids in reducing the period of urinary retention. METHODS: We reported a new case of MRS in a male adolescent. We also reviewed the previously 28 reported cases of MRS, collected from inception up to September 2022. RESULTS: MRS is characterized by aseptic meningitis and urinary retention. The mean length of the interval between the onset of the neurological signs and the urinary retention was 6.4 days. In most cases, no pathogens were isolated in cerebrospinal fluid, except for 6 cases in which Herpesviruses were detected. The urodynamic study resulted in a detrusor underactivity, with a mean period for urination recovery of 4.5 weeks, regardless of therapies. DISCUSSION: Neurophysiological studies and electromyographic examination are not pathological, distinguishing MRS from polyneuropathies. Although there are no encephalitic symptoms or signs, and the magnetic resonance is often normal, MRS may represent a mild form of acute disseminated encephalomyelitis, without radiological detectable medullary involvement, due to the prompt use of steroids. It is believed that MRS is a self-limited disease, and no evidence suggests the effectiveness of steroids, antibiotics, and antiviral treatment in its clinical course.

ABSTRACT

Acute hemichorea can occur in the context of infectious, autoimmune, metabolic, toxic, and vascular neuropathologies. Primary infection by varicella zoster virus (VZV) can result in vasculopathy with neurological manifestations, such as hemiparesis, at times accompanied by hemichorea. Isolated hemichorea, however, had not been reported. We here describe two cases of VZV-induced vasculopathy whose sole clinical manifestation was acute hemichorea. Both cases involved young boys of 3 years of age, who presented with acute hemichorea 4-6 months after initial VZV infection. All hematological, immunological, and toxicological tests were normal, except for the presence of VZV IgG. Brain structural magnetic resonance imaging (MRI) and magnetic resonance angiography revealed specific signs of vasculitis and ischemic lesions in the basal ganglia region (lentiform nucleus, thalamus, and internal capsule). Following corticosteroid and acetylsalicylic acid treatment, full symptomatic recovery was achieved within 3 weeks. Repeated MRI documented full neurostructural recovery, which was confirmed at extended follow-up for more than 1 year. These cases indicate that VZV-induced vasculopathy should be considered in the case of pediatric isolated acute hemichorea.
