Since aku mengendalikan pesakit dengan pelbagai masalah, di sini aku ingi share antara syndrome-syndrome yang berkaitan dengan Speech and Language Disorders.. Dan juga untuk rujukan aku terutama untuk jenis2 syndrome yang jarang kita jumpa..

CRI DU CHAT SYNDROME
Cri du chat syndrome is a group of symptoms that result from missing a piece of chromosome number 5. The syndrome’s name is based on the infant’s cry, which is high-pitched and sounds like a cat.
Cri du chat syndrome is rare. It occurs when a piece of information on chromosome 5 is missing. It is likely that multiple genes on chromosome 5 are deleted. One deleted gene, called TERT (telomerase reverse transcriptase) is involved in control of cell growth, and may play a role in how some of the features of this syndrome develop.
Most cases are believed occur during the development of an egg or sperm. A minority of cases result from one parent carrying a rearrangement of chromosome 5 called a translocation.
Between 1 in 20,000 – 50,000 babies are affected. This disease may account for up to 1% of individuals with severe mental retardation.
- Cry that is high-pitched and sounds like a cat
- Downward slant to the eyes
- Low birth weight and slow growth
- Low-set or abnormally shaped ears
- Mental retardation
- Partial webbing or fusing of fingers or toes
- Single line in the palm of the hand (simian crease)
- Skin tags just in front of the ear
- Slow or incomplete development of motor skills
- Small head (microcephaly)
- Small jaw (micrognathia)
- Wide-set eyes
In addition to symptoms, the physical examination may show:
- Inguinal hernia
- Diastasis recti (separated abdominal muscles)
- Low muscle tone
- Epicanthal folds, an extra fold of skin over the inner corner of the eye
- Incompletely or abnormally folded external ears
Genetic tests can show a missing part of chromosome 5. Skull x-ray may reveal an abnormal angle to the base of the skull.
No specific treatment is available for this syndrome. The mental retardation must be addressed, and counseling is recommended for the parents.
Parents of a child with this syndrome should have genetic counseling and a karyotype test to determine if one parent has a rearrangement of chromosome 5.
The outcome varies but mental retardation is usual. Half of those children affected learn sufficient verbal skills to communicate. The cat-like cry becomes less apparent over time.
Complications depend on the extent of mental retardation and physical abnormalities. Complications may include:
- Inability to care for self
- Inability to function in society
