ATP1A3-related disorders in the differential diagnosis of acute brainstem and cerebellar dysfunction.

Alternating Hemiplegia of Childhood (AHC), Rapid-onset Dystonia-Parkinsonism (RDP), and CAPOS syndrome (Cerebellar ataxia, Areflexia, Pes cavus, Optic atrophy, and Sensorineural hearing loss) are all caused by mutations in the same gene: ATP1A3. Although initially they were considered separate disorders, recent evidence suggests a continuous clinical spectrum of ATP1A3-related disorders. At onset all these disorders can present with acute brainstem dysfunction triggered by a febrile illness.

Long-term normalization of cognitive and psychopathological alterations in a juvenile Niemann-Pick type C case.

Niemann-Pick type C (NP-C) disease is a neurovisceral atypical lysosomal lipid storage disorder with a poor prognosis. We present the 5-year neuropsychological follow-up of a patient with juvenile onset NP-C, spanning the pre-diagnostic stage to the period after treatment with miglustat (Actelion Pharmaceuticals Inc., CA, US).

Enterovirus A71 Infection and Neurologic Disease, Madrid, Spain, 2016.

We conducted an observational study from January 2016 through January 2017 of patients admitted to a reference pediatric hospital in Madrid, Spain, for neurologic symptoms and enterovirus infection. Among the 30 patients, the most common signs and symptoms were fever, lethargy, myoclonic jerks, and ataxia. Real-time PCR detected enterovirus in the cerebrospinal fluid of 8 patients, nasopharyngeal aspirate in 17, and anal swab samples of 5.

Detection by Urinary GAG Testing of Mucopolysaccharidosis Type II in an At-Risk Spanish Population.

Hunter syndrome (Mucopolysaccharidosis type II) is an inherited lysosomal storage disorder with potentially severe degenerative consequences. Clinical diagnosis is not easy, although biochemical confirmation is straightforward, and sometimes patients are diagnosed at a late age. It is widely believed, for inborn errors of metabolism in general, that early diagnosis and management is of paramount importance for improving the prognosis of the disease.

Phenytoin-induced visual disturbances mimicking Delirium Tremens in a child.

Delirium Tremens is quite rare in children and it is usually caused by withdrawal or abstinence from alcohol, barbiturates and other major tranquilizers. The usual symptoms of Delirium Tremens include severe altered mental status with confusion, delusions, hallucinations, and severe agitation. Although psychosis is a recognized manifestation of Phenytoin toxicity, visual hallucinations are not.
