1/35. Terminal osseous dysplasia and pigmentary defects: clinical characterization of a novel male lethal X-linked syndrome.We describe a new syndrome of distal limb anomalies and pigmentary skin defects in 10 females of a large, four-generation pedigree. The family was ascertained through a 4-month-old infant girl with multiple anomalies, including hypertelorism, iris colobomas, low-set ears, midface hypoplasia, punched-out pigmentary abnormalities over the face and scalp, generalized brachydactyly, and digital fibromatosis. No affected males were identified in this pedigree. Affected females had a lower than normal male-to-female ratio of liveborn offspring, and some of them also had a history of several miscarriages. These findings, together with a significant variability in the phenotype of the affected females, suggest that this condition is inherited in an X-linked dominant fashion, with prenatal male lethality, and that X-inactivation plays an important role in the phenotypic expression of the disease. The syndrome has been described twice in the literature, but only in sporadic cases; it was therefore not recognized as a mendelian entity. Because the most consistent findings are anomalies of the distal skeleton of the limbs and localized pigmentary abnormalities of the skin, we named the syndrome "terminal osseous dysplasia with pigmentary defects." This condition, though rare, can be added to the small group of male lethal X-linked dominant disorders in humans.- - - - - - - - - - ranking = 1keywords = hypertelorism (Clic here for more details about this article) |
2/35. A mild case of frontonasal dysplasia: the rhinologic perspective.Frontonasal dysplasia (FND) is a congenital malformation characterized by hypertelorism, broad nasion with a midline cleft in the bony dorsum, midline defect of the frontal bone, absence of the nasal tip, and deformities in the nasal alar region. The clinician should be aware of the mild forms of FND. We presented absence of crista galli in a mild case of FND. Computed tomography scanning should assess the facial bones, nose, and paranasal structures. If a surgical correction is planned, this complete work-up prevents unexpected complications and complements the evaluation of paranasal deformities.- - - - - - - - - - ranking = 1keywords = hypertelorism (Clic here for more details about this article) |
3/35. Oto-palato-digital syndrome type II. Report of two related cases.Two cases with major features of bowed long bones, hypertelorism, mandibular hypoplasia and hand and foot abnormalities with early neonatal death due to respiratory failure are presented. The radiologic and clinical findings are in keeping with oto-palato-digital syndrome type II and differ significantly from other causes of bowed long bones such as campomelic and kyphomelic dysplasias.- - - - - - - - - - ranking = 1keywords = hypertelorism (Clic here for more details about this article) |
4/35. Prenatal and postnatal findings in a case with the autosomal recessive type of Robinow syndrome.OBJECTIVE: Our aim was to present a prenatally diagnosed case with Robinow syndrome in a consanguineous couple and discuss possible differential diagnosis in view of the literature. methods: A 28-year-old pregnant woman gravida 2 para 1 was referred to the obstetric clinic of Kahramanmaras Sutcu Imam University presenting with a fetus having shortened upper and lower limbs at 33 weeks of gestation. Her medical history was unremarkable except for consanguinity. Prenatal ultrasonographic examination revealed a reduced humerus and femur length. Further, shortening of the forearm, frontal bossing, mild hypertelorism, reduced thoracic perimeter and hemivertebrae at the thoracic level were present. RESULTS: Meticulous neonatal examination was performed following an uncomplicated vaginal delivery at 39 weeks of gestation. Distinct facial appearance in addition to the prenatal findings argued in favor of the diagnosis of Robinow syndrome. Additionally, radiological survey revealed and confirmed shortening of the upper extremities and thoracic hemivertebrae. CONCLUSION: We are documenting the case on the account of its rarity and additional features. The main approach in the differential diagnosis of Robinow syndrome should determine whether hemivertebrae is isolated or part of a syndrome or association.- - - - - - - - - - ranking = 1keywords = hypertelorism (Clic here for more details about this article) |
5/35. Computerized tomographic analysis of orbital hypertelorism repair: spatial relationship of the globe and the bony orbit.Computerized tomographic scans provide a new means of evaluating the spatial and geometric relationships between the movement of the bony orbit and its soft tissue contents (the globe and extraocular muscles) [1, 12]. Preoperative and postoperative computerized tomographic scans were analyzed in four patients to explore these relationships. Measurement of the changes in distance between the globes correlated most closely with the change in the distance between the lateral orbital walls; resection of medial (inter-orbital) bone provides space into which the globe is translocated. The medial rectus muscle may be bowed across the medial wall osteotomy line, creating a functional shortening of the muscle; this finding may explain the esotropia that is commonly seen after this procedure [2, 3]. These observations should have a direct impact on the understanding and planning of orbital hypertelorism correction.- - - - - - - - - - ranking = 5keywords = hypertelorism (Clic here for more details about this article) |
6/35. Oculodentodigital dysplasia. Four new reports and a literature review.Four new patients with oculodentodigital dysplasia (ODD) have been examined. The salient and fairly constant features of ODD appear to be (1) unique facial appearance, (2) microcornea with other inconstant ocular findings, (3) syndactyly of the hands with additional characteristic phalangeal aberrations, (4) diffuse skeletal dysplasia, (5) enamel dysplasia, and (6) trichosis. Echographic studies indicate that ODD globes have microcornea with otherwise normal dimensions. An increased number of vessels crossing the optic discs was observed in three patients from one family. The distance between the inner canthi and the medial orbital walls in three patients we studied suggests that previous reports of hypertelorism may have been illusions resulting from microcornea, small palpebral fissures, and variably present epicanthus.- - - - - - - - - - ranking = 1keywords = hypertelorism (Clic here for more details about this article) |
7/35. Autosomal recessive Robinow syndrome.Two brothers of normal first-cousin parents were found to have Robinow syndrome. Their paternal uncle also married a first cousin and had 3 similarly affected children (2 boys, 1 girl). The 2 affected brothers had short stature, mesomelic and acromelic brachymelia, characteristic face with hypertelorism, wide palpebral fissures, midface hypoplasia and large mouth, and hypogenitalism. Parental consanguinity and affected individuals in 2 sibships of common ancestry strongly suggest autosomal recessive inheritance. Similar cases from the literature are briefly reviewed.- - - - - - - - - - ranking = 1keywords = hypertelorism (Clic here for more details about this article) |
8/35. Ocular and systemic findings in the Aarskog (facial-digital-genital) syndrome.The Aarskog (facial-digital-genital) syndrome is an X-linked disorder in which short stature is accompanied by hypertelorism, digital anomalies, and shawl scrotum. Except for hypertelorism and blepharoptosis, ophthalmic abnormalities have been rarely noted in this condition. We examined four patients who had Aarskog syndrome and unilaterally or bilaterally decreased vision on initial examination. Three family members had V-pattern esotropia, latent nystagmus, inferior oblique overaction, and amblyopia. A fourth patient had bilateral blepharoptosis and severe astigmatism. Other ocular features included hyperopia, anisometropia, deficient ocular elevation, blue sclerae, and posterior embryotoxon. These findings underscore the need for ophthalmic examination in asymptomatic patients with Aarskog syndrome to rule out treatable causes of visual loss.- - - - - - - - - - ranking = 2keywords = hypertelorism (Clic here for more details about this article) |
9/35. Autosomal recessive inheritance of a syndrome of hypertelorism, hypospadias, and tetralogy of fallot?We report on 3 brothers with hypertelorism, hypospadias, and tetralogy of fallot. parents are first cousins once removed; the father has apparent hypertelorism. An apparently normal paternal uncle who is married to a second cousin also has a daughter with hypertelorism and tetralogy of fallot. All similarly affected relatives have mild or borderline mental retardation. The combination of anomalies may represent a previously undescribed autosomal recessive disorder.- - - - - - - - - - ranking = 7keywords = hypertelorism (Clic here for more details about this article) |
10/35. 3C syndrome: third occurrence of cranio-cerebello-cardiac dysplasia (Ritscher-Schinzel syndrome).We report a child with an unusual pattern of malformations: severe delay in bone maturation, wide fontanelles and facial dysmorphism (evoking cleidocranial dysplasia), relative macroencephaly with cerebellar vermis hypoplasia, hypertelorism, skeletal abnormalities (1st ribs aplasia, multifocal sternal ossification centers, thin bones), septal defect, muscular waste, hypotonia and developmental delay. Most of these features have been reported previously by Ritscher, Schinzel et al. in two sibs, who suffered more severe cerebellar malformations (Dandy-Walker cyst or vermis aplasia). We propose 3C syndrome as an easy acronym for this Cranio-Cerebello-Cardiac dysplasia.- - - - - - - - - - ranking = 1keywords = hypertelorism (Clic here for more details about this article) |
