[Syndromes 2. Pfeiffer syndrome].

Acrocephalosyndactylias are syndromes characterized by abnormalities of the head (craniosynostosis), the face (hypertelorism, retromaxillism), hands and feet (cutaneous or bony syndactyly). Inheritance is autosomal dominant, but spontaneous cases are described also. The group is divided into several syndromes with varying penetrance and expressivity. As an example of an acrocephalosyndactylia is the Pfeiffer syndrome presented.

Apert syndrome: analysis of associated brain malformations and conformational changes determined by surgical treatment.

Apert Syndrome, also called acrocephalosyndactylia type 1, is characterized by craniostenosis with early fusion of sutures of the vault and/or cranial base, associated to mid-face hypoplasia, symmetric syndactylia of the hands and feet and other systemic malformations. CNS malformations and intracranial hypertension are frequently observed in these patients. Early surgical treatment aims to minimize the deleterious effects of intracranial hypertension. Fronto-orbital advancement, the usual surgical technique, increases the intracranial Volume and improves the disposition of encephalic structures previously deformed by a short skull. This study analyzes CNS alterations revealed by magnetic resonance in 18 patients presenting Apert Syndrome, and the conformational alterations in the encephalic structures after surgical treatment. The patients' age in February 2001 ranged from 14 to 322 Months (m=107). Image study included brain magnetic resonance showing ventricular enlargement in five cases (27.8%), corpus callosum hypoplasia in five cases (27.8%), septum pellucidum hypoplasia in five cases (27.8%), cavum vergae in two cases (11.1%) and, arachnoid cyst in the posterior fossa in two cases (11.1%). Absence of CNS alterations was noted in 44.4% of cases. A corpus callosum morphologic index was established by dividing its height by its length, which revealed values that ranged from 0.4409 to 1.0237. The values of this index were correlated to the occurrence or absence of surgical treatment (p=0.012; t=2.83). Data analysis allowed the conclusion that the corpus callosum morphologic measure quantified the conformational alterations of the cerebral structures determined by the surgical treatment.

[Apert's syndrome: a case report].

Apert's syndrome is a type of acrocephalosyndactylia that is from part of the great group of craniofacial synostoses. It is characterized by craniofacial dysmorphia and syndactylia on hands and feet, which differentiates it from Crouzon's disease. It is a rare affection that is often transmitted through an autosome dominant mode, but sporadic cases exist. We report the case of a 15-year-old girl who presented characteristic clinical signs of Apert's syndrome with normal karyotype without parental consanguinity. The Ser 252 Trp mutation of the FGFR2 gene was found, confirming the molecular diagnosis. This study illustrates the severity of ocular and neurological problems of untreated Apert's syndrome. The presence of hemoglobinopathy (Hb AS) is also a mark of its originality.

[Apert syndrome: a reported observation].

Apert syndrome is a type of acrocephalosyndactylia that belongs to the group of craniofacial synostoses. It is characterised by craniofacial dysmorphia and syndactyly of hands and feet. It is an uncommon affection that is often transmitted through an autosomal dominant mode, but sporadic cases are frequent. We report the case of a 2 months old baby brought by his parents to the paediatric emergencies for respiratory distress occurring within the framework of a polymalformative syndrome. The examination showed brachycephaly, bilateral exorbitism, syndactyly of the hands and feet and an anal fistula. Echocardiographic examination showed a cardiovascular malformation (interventricular communication), the whole suggestive of Apert syndrome. The child was admitted in intensive care during five days. He died following a respiratory infection. Through this observation the authors illustrate the clinical and evolutionary aspects as well as the therapeutic difficulties of this affection.

[Syndrome of craniosynostosis with syn- or polydactylia].

Since the first description of the acrocephalosyndactyly syndrome, type Apert, in 1906, numerous entities belonging to this group of disorders have been defined. Recently several families with various types of craniosynostosis have been published. Moreover, most of the types of acrocephalosyndactylia have been observed with polydactyly, rendering exact diagnosis more and more difficult. Hence it seems necessary to revise the classification of these disorders. The paper gives a survey of the craniosynostosis syndromes and a classification for genetic counseling is proposed.

[Carpenter's syndrome].

A newborn boy presented with an acrocephaly characterized by a coronal craniosynostoses, open sagittal sutures and abnormally high and straight forehead. He was the only child of young, unrelated, healthy parents; there was no familial history of dysmorphy. Facial asymmetry was important and associated with posterior cleft palate, syndactylia of the tips and polydactylia of feet, due to a splitting of the first metatarsus. The child also had a congenital heart disease, like in half of the 15 published cases. In older children, mental retardation is usually observed, often associated with obesity and hypogonadism. Polydactylia permitted to exclude Apert's acrocephalosyndactylia in which there is a normal number of finger arms and which seems to be a dominant mutation, while the transmission of Carpenter's syndrome appears autosomal recessive, thus requiring restrictive genetic counselling.

Apert's syndrome.

This paper describes two cases of acrocephalosyndactylia (Apert's syndrome). Both very clearly showed the characteristic malformations. In addition, both patients showed synostosis between the calcaneus and the cuboid bone; this synostosis is not a typical feature of Apert's syndrome, but has been described in the literature once before.
