Cleidocranial dysplasia is a condition that primarily affects the development
of the bones and teeth.
What are the symptoms and signs of cleidocranial dysplasia?
Signs and symptoms of cleidocranial dysplasia can vary
widely in severity, even within the same family.
Individuals with cleidocranial dysplasia usually have underdeveloped or
absent collarbones (clavicles). As a result, their shoulders are narrow and
sloping, can be brought unusually close together in front of the body, and in
some cases the shoulders can be made to meet in the middle of the body. Delayed
closing of the spaces between the bones of the skull (fontanels) is also
characteristic of this condition. The fontanels usually close in early
childhood, but may remain open into adulthood in people with this disorder.
Affected individuals may be 3 to 6 inches shorter than other members of their
family, and may have:
Individuals with cleidocranial dysplasia may have
decreased bone density
(osteopenia) and may
develop osteoporosis, a condition that makes bones progressively more brittle
and prone to fracture, at a relatively early age.
Women with cleidocranial dysplasia have an increased risk of requiring a
cesarean section when delivering a baby, due to a narrow pelvis preventing
passage of the infant's head.
Dental abnormalities seen in cleidocranial dysplasia may
include:
delayed loss of the primary (baby) teeth;
delayed appearance of the
secondary (adult) teeth;
unusually shaped, peg-like teeth;
misalignment of the
teeth and jaws (malocclusion); and
extra teeth, sometimes accompanied by
cysts
in the gums.
In addition to skeletal and dental abnormalities, people
with cleidocranial dysplasia may have hearing loss and be prone to
sinus and
ear
infections. Some young children with this condition are mildly delayed in the
development of motor skills such as crawling and walking, but intelligence is unaffected.
Sinus infection (sinusitis) signs and symptoms include headache, fever, and facial tenderness, pressure, or pain. Treatments of sinus infections are generally with antibiotics and at times, home remedies.
Scoliosis causes an abnormal curvature of the spine. When the cause of scoliosis is unknown the disorder is described based on the age when the scoliosis develops (infantile, juvenile, or adolescent idiopathic scoliosis). In functional scoliosis, curvature develops due to a problem somewhere else in the body. With neuromuscular scoliosis, there is a problem when the bones of the spine are formed. Treatment typically involves observation, bracing, and surgery and is dependent upon the severity of the curvature.
Middle ear infection or inflammation (otitis media) is inflammation fo the middle ear. There are two types of otitis media, acute and chronic. Acute otitis media is generally short in duration, and chronic otitis media generally lasts several weeks. Seventy-five percent of children in the U.S. suffer from otitis media at some point. Treatment depends upon the type (chronic or acute).
Genetic disease is a disorder or condition caused by abnormalities in a person's genome. Types of genetic inheritance include single inheritance (for example, cystic fibrosis, sickle cell anemia, Marfan syndrome, and hemochromatosis), multifactoral inheritance, chromosome abnormalities (for example, Turner syndrome, and Klinefelter syndrome), and mitochondrial inheritance (for example, epilepsy and dementia).
Swimmer's ear (external otitis) is an infection of the skin that covers the outer ear canal. Causes of swimmer's ear include excessive water exposure that leads to trapped bacteria in the ear canal. Symptoms include a feeling of fullness in the ear, itching, and ear pain. Chronic swimmer's ear may be caused by eczema, seborrhea, fungus, chronic irritation, and other conditions. Common treatment includes antibiotic ear drops.
Sinus infections are caused by infections from a pathogenic microorganism
(virus, bacterium, or fungus), which grows within a sinus and causes
intermittent blockage of the sinus ostium.
Most people do not transmit sinus infections; most clinicians agree that except for rare instances, sinus infections are
not contagious but arise from mainly viruses and bacteria that, by chance, contaminate a person who sinuses support their proliferation because of minor, and rarely, major abnormalities in the person's sinus tissue (for example, swelling, inflammation, abnormal mucus production, and rarely, facial or nasal trauma).
Sinusitis is inflammation of the air cavities within the passages of the
nose. Sinusitis can be caused by infection, but also can be caused by allergies
and chemical or particulate irritation of the sinuses.
Sinusitis may be classified in several ways such as acute sinus infec...
