Maroteaux-Lamy syndrome exhibits deficient activity of the enzyme arylsulfatase-B in cultured skin fibroblasts. Prenatal diagnosis was successfully attempted in two pregnancies of a consanguineous Chaldean couple whose first child is affected with Maroteaux-Lamy syndrome. In both instances, deficient arylsulfatase-B activity was observed in amniotic fluid cell cultures, and the diagnosis was co...

The role of the genetic disorders in maxillofacial manifestations is well documented. Maroteaux Lamy syndrome (mucopolysaccharidosis VI) is a metabolic and chromosomal abnormality which involving disturbances in mucopolysaccharide metabolism and storage of acid mucopolysaccharide in various tissues. The main factor for Maroteaux Lamy syndrome is defi ciency of arylsulfatase B. Deposition of muc...

Mucopolysaccharidosis type VI or Maroteaux Lamy syndrome is an autosomal recessive lysosomal storage disorder resulting from a deficiency of arylsulfatase B, the clinical features include short stature, hepatosplenomegaly, dysostosis multiplex, stiff joints, corneal clouding, cardiac abnormalities, and facial dysmorphism, with intelligence usually normal. We present evidence of the possible exi...

The case is reported of a young woman with the Maroteaux-Lamy syndrome (mucopolysaccharidosis type VI) who presented with rapidly progressive dyspnoea due to mitral stenosis. Mitral valve replacement was performed and the appearance of the valve was typical of mucopolysaccharide infiltration. Dyspnoea in patients with the Maroteaux-Lamy syndrome may be due primarily to cardiac valve involvement...

The first 2 reported cases of a mucopolysaccharidosis occurring in an Australian aboriginal family are presented. Though these children had the characteristic morphological features of the Hurler syndrome, enzyme assay of cultured fibroblasts showed normal levels of alpha-L-iduronidase and decreased activity of arylsulphatase B. Thus, they represented the Hurler syndrome clinically, while they...

BACKGROUND Maroteaux-Lamy syndrome is a lysosomal storage disease of mucopolysaccharide metabolism (MPS type VI) that may involve the mitral and aortic valves. Affected patients have other skeletal and oropharyngeal malformations that complicate anesthetic and surgical management. METHODS AND RESULTS The present report describes the clinical, echocardiographic, and pathological findings in fo...

Maroteaux-Lamy syndrome (mucopolysaccharidosis type VI) is a rare lysosomal storage disorder in which the pathologic storage of glycosaminoglycans in various tissues can lead to severe symptoms, including cardiomyopathy. We report on a child with Maroteaux-Lamy syndrome whose cardiac condition deteriorated and eventually led to cardiac failure at the age of 7 years due to severe mitral regurgit...

Mucopolysaccharidoses (MPSs) are a group of metabolic diseases transmitted in an autosomal recessive fashion. MPSs are due to deficiencies of the specific enzymes responsible for the catabolism of dermatan sulfate, heparin sulfate, and keratan sulfate, resulting in the accumulation of glycosaminoglycans (GAGs). MPSs have a chronic, progressive course with multisystemic involvement. The incidenc...

Pycnodysostosis (the Toulouse-Lautrec syndrome) is a rare autosomal-recessive disorder of osteoclast dysfunction. This disorder was first described by Maroteaux and Lamy in 1962. We describe anaesthetic management of a 35-year-old female having pyknodysostosis with fracture shaft left femur with anticipated difficult intubation. Therefore, spinal anesthesia was planned for her fracture fixation...
