Outbreak of Enterovirus Infection with Neurological Presentations in a Pediatric Population in Northern Spain: A Clinical Observational Study.

Objective: The study aimed to describe the cases of neurological disease related to the outbreak of enterovirus (EV) in three regions in Northern Spain during 2016.

Materials And Methods: Multicenter retrospective observational study. Clinical, radiological, and microbiological data were analyzed from patients younger than 15 years with confirmed EV-associated neurological disease admitted to 10 hospitals of Asturias, Cantabria, and Castile and Leon between January 1 and December 31, 2016.

Assessment of a targeted resequencing assay as a support tool in the diagnosis of lysosomal storage disorders.

Background: With over 50 different disorders and a combined incidence of up to 1/3000 births, lysosomal storage diseases (LSDs) constitute a major public health problem and place an enormous burden on affected individuals and their families. Many factors make LSD diagnosis difficult, including phenotype and penetrance variability, shared signs and symptoms, and problems inherent to biochemical diagnosis. Developing a powerful diagnostic tool could mitigate the protracted diagnostic process for these families, lead to better outcomes for current and proposed therapies, and provide the basis for more appropriate genetic counseling.

Initiation and discontinuation of substrate inhibitor treatment in patients with Niemann-Pick type C disease.

Niemann-Pick type C disease (NP-C) is a lysosomal storage disorder characterized by a progressive neurological deterioration. Different clinical forms have been defined based on patient age at neurological symptoms onset: perinatal, early infantile (EI), late infantile (LI), juvenile and adult. There is no curative treatment for NP-C.

Infantile neuronal ceroid lipofuscinosis: follow-up on a Spanish series.

Infantile neuronal ceroid lipofuscinosis (INCL; NCL1, Haltia-Santavuori disease) is caused by mutations in the CLN1/PPT gene which are associated with an early onset INCL phenotype. The most detailed descriptions of INCL have come from Finland and a few series have been reported from southern European countries. Clinical course and follow-up of six Spanish patients with INCL are reported with the aim of assessing the chronological evolution and severity of this disease.

Juvenile neuronal ceroid lipofuscinosis: clinical course and genetic studies in Spanish patients.

Background: Juvenile neuronal ceroid lipofuscinosis (JNCL, NCL3, Batten disease) is usually caused by a 1.02-kb deletion in the CLN3 gene. Mutations in the CLN1 gene may be associated with a variant form of JNCL (vJNCL).
