Pseudo-Hurler Polydystrophy

Mucolipidosis III


Presentation

  • A comparison of biochemical results and the clinical picture of our patients with cases in the literature is presented.[ncbi.nlm.nih.gov]
  • Affected cells show dense inclusions filled with storage material, and lysosomal enzymes are present at elevated levels in the plasma and body fluids of affected patients.4.[fis-uke.de]
Short Stature
  • By the time afflicted individuals reach 4 to 6 years of age most will manifest with claw-hand deformities, scoliosis, and short stature.[themedicalbiochemistrypage.org]
  • Individuals with mucolipidosis III alpha/beta grow slowly and have short stature. They also have stiff joints and dysostosis multiplex, which refers to multiple skeletal abnormalities seen on x-ray.[ismrd.org]

Failure to Thrive
  • Children at risk for failure to thrive (growth failure) may need nutritional supplements, especially iron and vitamin B12 for persons with ML IV. Respiratory infections should be treated immediately and fully with antibiotics.[ninds.nih.gov]

Treatment

  • You can help by adding to it. ( May 2017 ) Treatment [ edit ] There is no cure for Pseudo-Hurler Polydystrophy/Mucolipidosis IIIA. Treatment is limited to controlling or reducing symptoms associated with this disorder.[en.wikipedia.org]

  • The resources below provide information about treatment options for this condition. If you have questions about which treatment is right for you, talk to your healthcare professional.[rarediseases.info.nih.gov]

Prognosis

  • Prognosis Symptoms of ML can be congenital (present at birth) or begin in early childhood or adolescence. Early symptoms can include skeletal abnormalities, vision problems and developmental delays.[ninds.nih.gov]

Etiology

  • Their etiology is not precisely century with the first clinical recognition of known, so we have included chapters that dis symptoms and patterns for diagnosis of car cuss many aspects of congenital cardiac mal diovascular diseases.[books.google.com]
  • They are organised into groups, and further divided into clinical, etiological or histopathological sub-types.[orpha.net]
  • The etiology of the disease remains unknown, but it is likely multifactorial. However, the genetic basis for this condition is defined by multiple genes that have only modest effect on disease susceptibility.[ped-rheum.biomedcentral.com]

Epidemiology

  • Epidemiology In 2005, Marsden et al compiled a report of physician narratives from an epidemiologic study regarding infantile-onset Pompe disease.[emedicine.medscape.com]

Pathophysiology

  • However, there is a great variability among patients - there are diagnosed individuals with ML III living in their sixties. [ citation needed ] Pathophysiology [ edit ] As in Mucolipidosis II, Mucolipidosis III results from genetic defects in GlcNAc phosphotransferase[en.wikipedia.org]

Prevention

  • ., mutations preventing the generation of active enzyme) in MLII and with mild mutations (i.e., mutations allowing the generation of active enzyme) in MLIIIA. Some cases of MLII and MLIIIA were the result of mutations that cause aberrant splicing.[ncbi.nlm.nih.gov]
  • Succinct, targeted coverage of normal childhood growth and development, as well as the diagnosis, management, and prevention of common pediatric diseases and disorders, make this an ideal medical reference book for students, pediatric residents, nurse[books.google.com]
  • Prevention of secondary complications : Because of concerns about airway management, surgical intervention should be undertaken only in tertiary care settings with pediatric anesthesiologists.[ismrd.org]
