Insights

Children with Morquio A disease experience poor growth and physical handicaps. This study developed growth charts for Morquio A patients, revealing impaired growth velocity after age one, aiding disease monitoring and treatment assessment.

Area of Science:

  • Pediatrics
  • Genetics
  • Metabolic Disorders

Background:

  • Morquio A disease causes significant growth impairment and physical disability in children due to systemic bone disease.
  • Understanding growth patterns is crucial for managing the condition and its associated health complications.

Purpose of the Study:

  • To establish growth curves for patients with Morquio A.
  • To analyze the relationship between growth patterns and the physical condition of affected individuals.
  • To provide a tool for monitoring disease progression and treatment efficacy.

Main Methods:

  • A one-center study involving 354 patients with Morquio A.
  • Utilized questionnaire-based longitudinal and cross-sectional data.
  • Developed growth charts and assessed physical activity and surgical incidence.

Main Results:

  • Mean final heights for males and females were significantly below normal (-7.4 and -7.7 SD, respectively).
  • Impaired growth velocity was observed after the first year of age.
  • Established normative growth data for Morquio A patients.

Conclusions:

  • This study presents the first growth charts specifically for Morquio A patients.
  • These charts are valuable for monitoring growth and evaluating therapeutic interventions.
  • The findings highlight the critical need for early diagnosis and management of growth issues in Morquio A.

Cytomegalovirus Disease

Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...
Myasthenia Gravis: Diagnostic Tests01:15

Myasthenia Gravis: Diagnostic Tests

Myasthenia gravis is an autoimmune condition affecting neuromuscular transmission, causing generalized weakness in skeletal muscles. Initial diagnoses rely on patients' signs, symptoms, and medical history. The challenge lies in distinguishing myasthenia from other muscular dystrophies. An important diagnostic feature is the significant improvement of symptoms after administering anticholinesterase inhibitors.
The edrophonium test is a diagnostic tool for myasthenia gravis. It involves...
Bone Disorders01:29

Bone Disorders

Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Cystic Fibrosis: Pathogenesis

Cystic fibrosis (CF), an autosomal recessive disorder, significantly affects the function of exocrine glands. This genetically inherited disease is characterized by the production of thick and sticky mucus, which can severely affect various organs and systems in the body.
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation, but...
Huntington Disease l: Introduction01:21

Huntington Disease l: Introduction

Huntington disease or HD is a progressive, fatal neurodegenerative disorder inherited in an autosomal dominant pattern.PathophysiologyIt is caused by expansion of the CAG trinucleotide repeat in the HTT gene on chromosome 4 (4p16.3), producing an abnormal huntingtin protein with an expanded polyglutamine tract. This misfolded protein disrupts cellular function, leading to neuronal death. Normal alleles have ≤26 repeats, 27–35 are intermediate (risk of expansion), 36–39 show reduced penetrance,...

Changes in the Appendicular Skeleton with Age

The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...
