Pinto,Raquel Borges; Ramos,Ana Regina Lima; Backes,Ariane Nadia; Santos,Beatriz John dos; Provenzi,Valentina Oliveira; Carbonera,Mário RafaelABSTRACT CONTEXT: Hirschsprung disease is a developmental disorder of the enteric nervous system that is characterized by absence of ganglion cells in the distal intestine, and it occurs in approximately 1 in every 500,000 live births. Hepatoblastoma is a malignant liver neoplasm that usually occurs in children aged 6 months to 3 years, with a prevalence of 0.54 cases per 100,000. CASE REPORT: A boy diagnosed w...
A patient presenting a 22q13 deletion associated with an apparently balanced tr...
Artigalás,Osvaldo; Paskulin,Giorgio; Riegel,Mariluce; Burin,Maira; Saraiva-Pereira,Maria Luiza; Maluf,Sharbel; Kiss,Andrea; Schwartz,Ida Vanessa D.A 10-year-old speechless, mentally deficient male, with low arylsulfatase A (ARSA) activity, and presumably, methachromatic leukodystrophy, underwent genetic evaluation. As the clinical picture was not compatible with this diagnosisan ARSA gene and chromosome analysis were performed, showing the presence of a pseudodeficiency ARSA allele and a de novo apparently balanced t(16;22)(p11.2;q13) translocation. A del...
Mucopolysaccharidosis I, II, and VI: brief review and guidelines for treatment
Giugliani,Roberto; Federhen,Andressa; Muñoz Rojas,Maria Verônica; Vieira,Taiane; Artigalás,Osvaldo; Lapagesse Pinto,Louise; Azevedo,Ana CecíliaMucopolysaccharidoses (MPS) are rare genetic diseases caused by the deficiency of one of the lysosomal enzymes involved in the glycosaminoglycan (GAG) breakdown pathway. This metabolic block leads to the accumulation of GAG in various organs and tissues of the affected patients, resulting in a multisystemic clinical picture, sometimes including cognitive impairment. Until the beginning of the XXI century, treat...

Giugliani,Roberto; Federhen,Andressa; Muñoz Rojas,Maria Verónica; Vieira,Taiane Alves; Artigalás,Osvaldo; Pinto,Louise Lapagesse CarmargoAs mucopolissacaridoses (MPS) são doenças genéticas raras causadas pela deficiência de enzimas lisossômicas específicas que afetam o catabolismo de glicosaminoglicanos (GAG). O acúmulo de GAG em vários órgãos e tecidos nos pacientes afetados pelas MPS resulta em uma série de sinais e sintomas, integrantes de um quadro clínico multissistêmico que compromete ossos e articulações, vias respiratórias, sistema cardi...
