Sex-linked Disorders01:43

Sex-linked Disorders

112.1K
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.

Immunodeficiency Diseases01:25

Immunodeficiency Diseases

3.3K
Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.
There are three main causes of immunodeficiency...

Learning Disabilities01:25

Learning Disabilities

749
Learning disabilities are cognitive disorders caused by neurological impairments that affect cognitive functions like language and reading, without indicating overall intellectual or developmental challenges. These disabilities differ from global intellectual or developmental disabilities as they are limited to distinct cognitive functions. Common learning disabilities include dysgraphia, dyslexia, and dyscalculia, each of which impacts unique aspects of learning.

Development of the Limb Synovial Joints01:07

Development of the Limb Synovial Joints

2.7K
Joints form during embryonic development in conjunction with the formation and growth of the associated bones. The embryonic tissue that gives rise to all bones, cartilage, and connective tissues of the body is called mesenchyme.
The mesenchymal stem cells differentiate into chondrocytes that form the hyaline cartilage, and later the cartilaginous model of the bone. This model further transforms into a bone. This process is known as endochondral ossification.
During development, the limbs...

Disorders of the Skeletal Muscle01:28

Disorders of the Skeletal Muscle

2.4K
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...

Area of Science:

  • Medical Genetics
  • Orthopedics
  • Developmental Biology

Background:

  • Congenital limb deficiency disorders (LDDs) are birth defects affecting limb bone development.
  • LDDs manifest as aplasia (complete absence) or hypoplasia (underdevelopment) of limb bones.
  • Classified as transverse (intrauterine disruption) or longitudinal (isolated or syndrome-associated).

Purpose of the Study:

  • To provide a comprehensive overview of congenital limb deficiency disorders.
  • To outline classification, diagnostic considerations, and management strategies for LDDs.
  • To emphasize the importance of specialized care and support for affected children.

Main Methods:

  • Literature review of congenital limb deficiency disorders.
  • Synthesis of current classification systems for LDDs.
  • Summary of recommended multidisciplinary care approaches.

Main Results:

  • LDDs encompass a spectrum of limb malformations.
  • Accurate classification aids in understanding etiology and prognosis.
  • Specialized care centers offer expertise in orthopedics, prosthetics, and therapy.

Conclusions:

  • Early consultation with medical geneticists is recommended for LDD diagnosis.
  • Long-term management requires a specialized limb deficiency center.
  • With appropriate care, children with LDDs can achieve productive lives.
