SINDROME DE CROUZON PDF

Crouzon syndrome: factors related to the neuropsychological development and to the quality of life. Crouzon syndrome is characterized by cranial and facial abnormalities and exophtalmos. Mental retardation is sometimes observed. The objective of this study was to correlate brain malformations, timing for surgery and also social classification of families and parents education to the neuropsychological evaluation and to the quality of life of these families.

The Spanish Association of Pediatrics has as one of its main objectives the dissemination of rigorous and updated scientific information on the different areas of pediatrics. Annals of Pediatrics is the Body of Scientific Expression of the Association and is the vehicle through which members communicate. The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two receding years.

CiteScore measures average citations received per document published. Read more. SRJ is a prestige metric based on the idea that not all citations are the same. SJR uses a similar algorithm as the Google page rank; it provides a quantitative and qualitative measure of the journal's impact. SNIP measures contextual citation impact by wighting citations based on the total number of citations in a subject field.

Crouzon syndrome

Alternative titles; symbols. Crouzon syndrome is an autosomal dominant disorder characterized by craniosynostosis causing secondary alterations of the facial bones and facial structure. Common features include hypertelorism, exophthalmos and external strabismus, parrot-beaked nose, short upper lip, hypoplastic maxilla, and a relative mandibular prognathism Reardon et al. Crouzon first described this syndrome in a family. Shiller observed autosomal dominant transmission of Crouzon craniofacial dysostosis in 23 family members spanning 4 generations. There was marked variability in both cranial and facial manifestations. Dodge et al.

Crouzon Syndrome

Crouzon syndrome is rare disorder characterized by premature craniosynostoses. It carries an autosomal dominant inheritance due to a mutation in fibroblast growth factor receptor 2 FGFR2 gene on chromosome 10q Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys.

Crouzon syndrome is an autosomal dominant genetic disorder known as a branchial arch syndrome. Specifically, this syndrome affects the first branchial or pharyngeal arch, which is the precursor of the maxilla and mandible. Since the branchial arches are important developmental features in a growing embryo , disturbances in their development create lasting and widespread effects. This syndrome is named after Octave Crouzon , [1] [2] a French physician who first described this disorder. First called "craniofacial dysostosis" " craniofacial " refers to the skull and face , and " dysostosis " refers to malformation of bone , the disorder was characterized by a number of clinical features which can be described by the rudimentary meanings of its former name. This syndrome is caused by a mutation in the fibroblast growth factor receptor 2 FGFR2 , located on chromosome The developing fetus's skull and facial bones fuse early or are unable to expand.
