Pleiotropy01:33

Pleiotropy

31.2K
Pleiotropy is the phenomenon in which a single gene impacts multiple, seemingly unrelated phenotypic traits. For example, defects in the SOX10 gene cause Waardenburg Syndrome Type 4, or WS4, which can cause defects in pigmentation, hearing impairments, and an absence of intestinal contractions necessary for elimination. This diversity of phenotypes results from the expression pattern of SOX10 in early embryonic and fetal development. SOX10 is found in neural crest cells that form melanocytes,...

Bone Disorders01:29

Bone Disorders

8.0K
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...

Sex-linked Disorders01:43

Sex-linked Disorders

94.4K
Like autosomes, sex chromosomes contain a variety of genes necessary for normal body function. When a mutation in one of these genes results in biological deficits, the disorder is considered sex-linked.

Bone Formation by Endochondral Ossification01:24

Bone Formation by Endochondral Ossification

14.6K
Bone formation, or ossification, begins around the sixth to seventh week of embryonic development. Most bones develop from a cartilaginous template through the process of endochondral ossification. Cartilage formation begins when clusters of mesenchymal cells differentiate into chondrocytes. These chondrocytes proliferate rapidly and secrete an extracellular matrix that becomes encased in a membrane called the perichondrium. The resulting cartilage model provides a template that resembles the...

The Retinoblastoma Gene01:20

The Retinoblastoma Gene

3.7K
Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

Disorders of the Skeletal Muscle01:28

Disorders of the Skeletal Muscle

2.2K
The clinical conditions affecting the skeletal muscle tissue are broadly categorized as musculoskeletal and neuromuscular disorders.
Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...

Summary

Multiple hereditary exostosis can cause spinal cord compression due to intraspinal osteochondromatosis. Surgical intervention for these spinal canal exostoses relieved neurological deficits in a pediatric patient.

Area of Science:

  • Orthopedics
  • Neurosurgery
  • Medical Genetics

Background:

  • Multiple hereditary exostosis (MHE) is a genetic disorder characterized by the development of multiple osteochondromas.
  • Spinal involvement in MHE is uncommon, but can lead to significant complications.
  • Intraspinal osteochondromas can cause spinal cord compression and neurological deficits.

Purpose of the Study:

  • To report a rare case of spinal cord compression in a 13-year-old boy with MHE.
  • To highlight the diagnostic findings and successful surgical management of intraspinal exostoses in MHE.
  • To emphasize the potential for MHE to cause severe neurological compromise.

Main Methods:

  • Case report of a 13-year-old male with MHE presenting with back pain and neurological deficits.
  • Spine radiography and reformatted CT scanning to evaluate thoracic vertebrae (T3-5) abnormalities.
  • Surgical decompression for intraspinal exostoses.

Main Results:

  • Radiographic and CT findings revealed cauliflower-like, intra- and extraspinal osteochondromatosis of thoracic vertebrae (T3-5).
  • The intraspinal exostoses were compressing the spinal cord.
  • Surgical treatment resulted in the cessation of neurological deficits.

Conclusions:

  • Spinal cord compression due to intraspinal osteochondromatosis is a rare but serious complication of MHE.
  • Early diagnosis and surgical intervention are crucial for managing neurological deficits in such cases.
  • This case underscores the importance of considering spinal involvement in MHE patients presenting with neurological symptoms.
