Dwarfism
Classification and external resources
ICD-9 253.3, 259.4

Dwarfism refers to a condition in individual plants or animals characterized by extreme small size. The International Statistical Classification of Diseases and Related Health Problems (most commonly known by the abbreviation ICD) provides codes to classify Diseases The following is a list of codes for International Statistical Classification of Diseases and Related Health Problems. In older popular and medical usage, any type of marked human smallness could also be termed dwarfism. The term as related to human beings (the major subject of this article) is often used to refer specifically to those forms of extreme shortness characterized by disproportion of body parts, typically due to an inheritable disorder in bone or cartilage development. A genetic disorder is a condition caused by abnormalities in Genes or Chromosomes While some diseases such as Cancer, are due to genetic abnormalities acquired

Forms of extreme shortness in humans characterized by proportional body parts usually have a hormonal or nutritional cause. An example is growth hormone deficiency, once known as "pituitary dwarfism". Growth Hormone Deficiency is the medical condition of inadequate production of Growth hormone (GH and it effects on children and adults

The Little People of America (LPA) defines dwarfism as a medical or genetic condition that usually results in an adult height of 4'10" (147 cm) or shorter. Little People of America ( LPA) is a Non-profit organization which provides support and information to those with Dwarfism and their families [1]

Types of dwarfism

When the cause of dwarfism is understood, it may be classified according to one of hundreds of names, which are usually permutations of the following roots:

Examples include achondroplasia, osseous dysplasia, chondrodystrophy, and osteochondrodystrophy. Achondroplasia is a type of Autosomal dominant Genetic disorder that is a common cause of Dwarfism. Chondrodystrophy (literally "cartilage bad-nourishment" refers to a Skeletal disorder caused by one of myriad genetic mutations that can affect the development [2]

The most recognizable and most common form of dwarfism is achondroplasia, which produces rhizomelic short limbs, increased spinal curvature, and distortion of skull growth. Achondroplasia is a type of Autosomal dominant Genetic disorder that is a common cause of Dwarfism. It accounts for 70% of dwarfism cases. Other relatively common types include spondyloepiphyseal dysplasia congenita (SED), diastrophic dysplasia, pseudoachondroplasia, hypochondroplasia, and osteogenesis imperfecta (OI). Spondyloepiphyseal dysplasia congenita (abbreviated to SED more often than SDC is a rare disorder of Bone growth that results in Dwarfism, characteristic skeletal Diastrophic dysplasia (DTD is an Autosomal Recessive Congenital disorder which affects Cartilage and Bone development Pseudoachondroplasia is a type of short-limb Dwarfism. It is a genetic autosomal dominant disorder Hypochondroplasia is a developmental disorder caused by an Autosomal dominant genetic defect in the Fibroblast growth factor receptor 3 gene ( FGFR3 Osteogenesis imperfecta ( OI and sometimes known as Brittle Bone Disease) is a genetic bone disorder Severe shortness with skeletal distortion also occurs in several of the mucopolysaccharidoses and other storage diseases. Mucopolysaccharidosis is a group of Autosomal recessive metabolic disorders caused by the absence or malfunctioning of lysosomal enzymes needed to break down The lysosomal storage diseases are a group of over forty human Genetic disorders that result from defects in lysosomal function

The average adult height of male and females with dwarfism is 132 cm and 123 cm respectively. The average weight of an adult may range from 100 to 150 pounds (45-68 kg).

Diagnosis

Unusually short stature for a child's age is usually what brings the child to medical attention. Skeletal dysplasia ("dwarfism") is usually suspected because of obvious physical features (e. Dysplasia (from Greek roughly "bad formation" is a term used in Pathology to refer to an abnormality in maturation of cells within a tissue g. , unusual configuration of face or shape of skull), because of an obviously affected parent, or because body measurements (arm span, upper to lower segment ratio) indicate disproportion. Bone x-rays are often the key to diagnosis of a specific skeletal dysplasia, but they are not the key diagnosis. Most children with suspected skeletal dysplasias will be referred to a genetics clinic for diagnostic confirmation and genetic counseling. Genetic counseling is the process by which patients or relatives at risk of an inherited disorder are advised of the consequences and nature of the disorder the probability of developing In the last decade, genetic tests for some of the specific disorders have become available.

During the initial medical evaluation for shortness, the absence of disproportion and the other clues above usually indicates other causes than bone dysplasias. Extreme shortness with completely normal proportions sometimes indicates growth hormone deficiency (pituitary dwarfism). Growth Hormone Deficiency is the medical condition of inadequate production of Growth hormone (GH and it effects on children and adults

Short stature alone, in the absence of any other abnormalities, may simply be genetic, particularly if a person is born into a family of people who are relatively short.

Problems associated with dwarfism

The principal adverse effects of dwarfism can be divided into the physical and the social.

Physical effects of malformed bones vary according to the specific disease. Many involve pain resulting from joint damage from abnormal bone alignment, or from nerve compression (e. A nerve is an enclosed cable-like bundle of peripheral Axons (the long slender projections of Neurons. g, spinal stenosis). Spinal stenosis is a medical condition in which the spinal canal narrows and compresses the spinal cord and nerves [1]. Early degenerative joint disease, exaggerated lordosis or scoliosis, and constriction of spinal cord or nerve roots can cause pain and disability. Lordosis (commonly referred to as swayback, saddle back, or hyper-lordosis) is a medical term used to describe an inward curvature of a portion of the Scoliosis is a medical condition in which a person's spine is curved from side to side and may also be rotated The spinal cord is a long thin tubular bundle of Nerves that is an extension of the Central nervous system from the brain and is enclosed in and protected Reduced thoracic size can restrict lung growth and reduce pulmonary function. The thorax is a division of an Animal 's body that lies between the head and the Abdomen. Some forms of dwarfism are associated with disordered function of other organs, such as the brain or liver, sometimes severely enough to be more disabling than the abnormal bone growth. The brain is the center of the Nervous system in animals All Vertebrates and the majority of Invertebrates have a brain The liver is a vital organ in the human body and is present in Vertebrates and some other animals As well, many dwarves are given injections of Human Growth Hormone during their early years, in the hope that it will increase their height, though, sadly, the HGH injections may cause adverse effects on the cardiac muscles, making them too large or thick to properly function, causing death through cardiac failure in the patient.

The psychosocial disadvantages may be more distressing than the physical symptoms, especially in childhood and adolescence, but people with dwarfism vary greatly in the degree to which social participation and emotional health are affected.

Treatment and support

As the genetic defects of most forms of dwarfism due to bone dysplasia cannot be corrected, therapeutic interventions are typically aimed at (1) preventing or reducing pain or physical disability, (2) increasing adult height, or (3) mitigating psychosocial stresses and enhancing social adaptation.

Pain and disability may be ameliorated by physical therapy, by braces or other orthotic devices, or by surgical procedures. The only simple interventions that increase perceived adult height are dress enhancements such as shoe lifts or hairstyle. Growth hormone is rarely used for shortness due to bone dysplasias, as the height benefit is typically small (less than 5 cm) and the cost high. The most effective means of increasing adult height by several inches is limb-lengthening surgery, though availability is limited and cost is high in terms of money, discomfort, and interruption of life. Distraction osteogenesis, also called callus distraction, callotasis is a surgical process used to reconstruct skeletal deformities Most people with dwarfism do not avail themselves of this, and it remains controversial. [1] For other types of dwarfism, surgical treatment is not possible.
