RESUMEN
Guillain-Barre syndrome (GBS) is an immune-mediated disease of the peripheral nerves and cause of acute flaccid paralysis in children around the world. The most common type of GBS in North America targets myelin and leads to demyelinating neuropathy. Often there is a history of infection in the weeks preceding motor symptoms. GBS has been associated with different infections, including COVID. Children usually recover motor function, but autonomic instability and respiratory compromise can occur necessitating close observation and potentially intensive care unit admission.

Multiple sclerosis can affect pediatric patients. Our aim was to compare characteristics between pediatric-onset multiple sclerosis and adult-onset multiple sclerosis in Hispanic Americans. This was a cross-sectional analysis of 363 Hispanic American multiple scleroses cases; demographic and clinical characteristics were analyzed. A total of 110 Hispanic patients presented with multiple sclerosis before age 18 and 253 as adult multiple sclerosis. The most common presenting symptoms for both was optic neuritis. Polyfocal symptoms, seizures, and cognitive symptoms at presentation were more prevalent in pediatric-onset multiple sclerosis (P ≤ .001). Transverse myelitis was more frequent in adult-onset multiple sclerosis (P ≤ .001). Using multivariable analysis, pediatric-onset multiple sclerosis (adjusted odds ratio, 0.3OR 95% confidence interval 0.16-0.71, P = .004) and being US born (adjusted odds ratio, 0.553, 95% confidence interval 0.3-1.03, P = .006) were less likely to have severe ambulatory disability. Results suggest that pediatric-onset multiple sclerosis and adult-onset multiple sclerosis in Hispanics have differences that could be important for treatment and prognosis.

We describe a case of pediatric neuromyelitis optica (NMO) with muscle and lung involvement in addition to central nervous system disease. Our patient initially presented with features of area postrema syndrome, then subsequently with optic neuritis. The patient also had recurrent hyperCKemia that responded to corticosteroids. Finally, axillary and hilar adenopathy with pulmonary consolidation were noted as well and responded to immunomodulation. Our case highlights multisystem involvement in NMO including non-infectious pulmonary findings which have not been described in the pediatric population previously.
RESUMEN
Encephalitis due to antibodies to voltage gated potassium channel (VGKC) typically presents with limbic encephalitis and medial temporal lobe involvement on neuroimaging. We describe a case of 13 year girl female with encephalitis due to antibodies to VGKC with signal changes in the cerebellar dentate nuclei bilaterally and clinical features that suggested predominant cerebellar involvement. These have never been reported previously in the literature. Our case expands the phenotypic spectrum of this rare condition.
RESUMEN
Association of occipital intermittent rhythmic delta activity with absence seizures has been well documented in the published literature. Two recent studies have also described an association with focal seizures. After obtaining approval from our Institutional Review Board, all electroencephalograms with occipital intermittent rhythmic delta activity at our institution between July 1, 2006 and December 31, 2009 were identified. Charts of these patients were reviewed to collect clinical data. A matched comparison group was assembled. Thirty-one of the patients who met criteria had evaluable clinical data. Fifteen had generalized seizures (9 absence; 2 tonic-clonic; 3 absence and tonic-clonic; 1 absence, tonic-clonic, myoclonic, and atonic). Eleven had focal seizures. One had both generalized tonic-clonic and focal seizures. Events in 1 were nonepileptic in nature. Documentation was inadequate for seizure classification in 3. There was a statistically significant difference between the study and comparison groups for absence seizures, but not for focal seizures.
