Cellular transplantation in the form of bone marrow has been one of the primary treatments of many lysosomal storage diseases (LSDs). Although bone marrow transplantation can help central nervous system manifestations in some cases, it has little impact in many LSD patients. Canine models of neurogenetic LSDs provide the opportunity for modeling central nervous system transplantation strategies...

A hitherto undescribed form of pattern dystrophy of the retinal pigment epithelium was found in a patient suffering from mucopolysaccharidosis II or Hunter's disease. We propose the name peripheral pattern dystrophy.

OBJECTIVE The first line-screening test for mucopolysaccharidosis is based on measurement of urinary glycosaminoglycans. The most reliable test for measurement of urine glycosaminoglycans is the 1,9-dimethyleneblue colorimetric assay. Biological markers are affected by ethnical factors, for this reason, the World Health Organization recommends that the diagnostic test characteristics should be ...

Introduction: We present the unexpected findings of a 59-years-old female patient who was admitted for an imaging investigation after the exclusion of rheumatoid arthritis and recurring carpal tunnel syndrome she was operated on both hands several years earlier. Case presentation: Magnetic resonance imaging of the cervical spine revealed severe scoliosis in the cervicothoracic junction with bic...

OBJECTIVE To describe the progression of ocular changes in patients with mucopolysaccharidosis I receiving enzyme replacement therapy. METHODS Three male and five female patients with mucopolysaccharidosis I were followed up for 4 years while undergoing enzyme replacement therapy with alpha-l-iduronidase (Aldurazyme). Visual acuity, corneal clouding, intraocular pressure, ophthalmoscopy, and ...

OBJECTIVE To assess the progression of mucopolysaccharidosis II in 11 Brazilian patients over a 12-month period. METHODS Eleven Brazilian patients with mucopolysaccharidosis II were prospectively studied at the Division of Medical Genetics of Hospital de Clínicas de Porto Alegre. The initial assessment and the assessment at 12 months included: anamnesis, physical examination, abdominal nuclea...

Mucopolysaccharidosis (MPS) are a group of metabolic disorders of the lysosomal storage disease family caused by the absence or malfunctioning of lysosomal enzymes, which blocks degradation of mucopolysaccharides and leads to abnormal accumulation of heparan sulfate, dermatan sulfate, and keratan sulfate. Morquio’s syndrome is a rare autosomal-recessive mucopolysaccharidosis. This syndrome is c...
