Clinical description of 41 Brazilian patients with oculo-auriculo-vertebral dysplasia / Displasia óculo-aurículo-vertebral: aspectos clínicos de 41 pacientes brasileiros

SUMMARY Objective: To describe the most prominent clinical features of a cohort of patients with oculo-auriculo-vertebral (OAV) dysplasia in Brazil. Method: A review of medical records of patients with diagnosis of OAV from 1990 to 2010 was performed in a medical genetics center. Results: 41 patients were included in the study. Their average age at diagnosis was 2y 10mo (34,4±48,8 months) and the female proportion was 53.7%. Mean maternal age at patient’s birth was 28.5y (min: 17, max: 46y) for mothers and 31.4y (min: 21, max: 51y) for fathers. Most patients (97.5%) had auricular involvement, with facial manifestation in 90.2%, spinal in 65.9%, ocular in 53.7%, 36.6% with cardiovascular involvement, 29.3% urogenital, and 17% of the cases with central nervous system (CNS) involvement. The classic OAV triad was present in only 34%. All patients except one had concomitant problems in other organs or systems. Conclusion: Since the diagnosis of OAV dysplasia relies only on a comprehensive medical evaluation, it is imperative that clinicians be aware of the most common presentation of the syndrome. Once suspected, every patient should undergo a complete medical evaluation of multiple systems including complementary exams. Treatment of these patients is based on surgical correction of malformations and rehabilitation.

RESUMO Objetivo: descrever os principais achados clínicos de uma coorte de pacientes com a displasia óculo-aurículo-vertebral (OAV). Método: revisão de prontuários médicos dos pacientes com diagnóstico de OAV no período de 1990 a 2010, acompanhados em um centro de genética médica. Resultados: foram incluídos no estudo 41 pacientes. A média de idade ao diagnóstico foi de 2 anos e 10 meses (34,4±48,8 meses) e a proporção de pacientes do sexo feminino foi de 53,7%. A média de idade dos pais ao nascimento do paciente foi de 28,5±6,9 anos para as mães e 31,4±7,4 anos para os pais. A maioria dos indivíduos (97,5%) possuía acometimento auricular, 90,2% tinham manifestações faciais, 65,9%, vertebrais, 53,7%, oculares, 36,6%, cardiovasculares, 29,3%, urogenitais e 17%, no sistema nervoso central. Além disso, 34% dos pacientes apresentavam a tríade clássica óculo-aurículo-vertebral, e todos os pacientes exceto um apresentavam concomitantemente problemas em outros órgãos ou sistemas. Conclusão: já que o diagnóstico desta entidade é eminentemente clínico, é imprescindível que os médicos das mais diversas especialidades conheçam os achados mais frequentes na OAV. Diante de um paciente com suspeita diagnóstica, deve ser realizada avaliação detalhada de outros órgãos, tanto clínica como por meio de exames complementares. O tratamento é baseado na correção cirúrgica das malformações e na reabilitação.

Wildervanck syndrome associated with cleft palate and short stature.

We report a case of Wildervanck syndrome exhibiting Klippel-Feil anomaly, Duane retraction syndrome and deafness. Since the first case was reported in 1952, there have been more reports describing this triad, either complete or incomplete. Our patient had the complete triad of the syndrome along with cleft palate and short stature. Also, a review of the literature regarding this syndrome is presented here.

Goldenhar syndrome with unusual features.

We report here the case of a 17 year-old girl with the classic signs of Goldenhar syndrome in the form of multiple accessory tragi, bilateral ocular dermoids, mandibular hypoplasia (micrognathia) and cervical lordosis. She also had a high arched palate, gingival hypertrophy and malaligned teeth, features which are as yet unreported.

Monozygotic twins discordant for Goldenhar syndrome

OBJECTIVE: To report on a pair of monozygotic female twins discordant for Goldenhar syndrome. DESCRIPTION: The affected twin was a girl, who was delivered by caesarean section at 35 weeks' gestation. Her birth weight was 2,170 g, length 42.5 cm, head circumference 30 cm and her Apgar scores were 3/7. After birth the child developed severe respiratory distress and had to be moved to the neonatal intensive care unit (ICU). The other twin was a girl, born weighing 3,200 g with a length of 49 cm, head circumference of 34 cm and Apgar scores of 8/10. She was transferred to the mother-baby unit soon after birth and was discharged two days later. There was no consanguinity between the twins' parents, who were young and healthy at the time of their conception. The affected child's dysmorphic features included left hemifacial microsomia, severe micrognathia, abnormal ears, bilateral preauricular tags and epibulbar dermoid in the right eye. She developed obstructive apnea due to micrognathia and required tracheostomy. Abdominal and cranial ultrasound findings were normal, as was an ophthalmological assessment. Spine x-ray showed hemivertebra at T9 and T10. An echocardiogram showed Tetralogy of Fallot. GTG-banded karyotyping was performed on peripheral blood cells and revealed 46,XX. Zygosity testing established the pair of twins to be monozygotic with a probability greater than 99:1. COMMENT: Goldenhar syndrome was diagnosed in one of the twins described here. There are several reports of twins discordant for this disorder and therefore non-genetic factors may also play an important role, for instance vascular disruption during morphogenesis.

Goldenhar's syndrome: case report

GoldenharÆs syndrome is a rare condition described initially in the early 1950Æs. It is characterized by a combination of anomalies: dermal epibulbar cysts, auricular appendices and malformation of the ears. In 1963, Gorlin suggested the name oculo-auriculo-vertebral (OAV) dysplasia for this condition and also included vertebral anomalies as signs of the syndrome. The etiology of this rare disease is not fully understood, as it has shown itself variable genetically and of unclear causes. This work reports a case of GoldenharÆs syndrome in an 11-year-old female, who presented all classical signs of this rare condition.

Microtia: A clinical and genetic study at the National Institute of Pediatrics in Mexico City

Background. Microtia is a malformation of the ear with extreme variability of expression. It is generally seean as an isolated malformation. However, some authors consider it to be a minimal manifestation of the oculo-auriculo-vertebral spectrum (OAVS), wherem, in addition, there are facial, vertebral, and renal abnormalities, among others. Methods. A total of 145 pediatric patients with unilateral or bilateral microtia not considered as part of a syndrome were studied. All patients were subjected to an international clinical examination, a familial history, and radiographic imaging studies for ruling out associated malformations. Patients were classified into two groups: group 1 (60 percent), with isolated microtia; and group 2 (40 percent), considered as OAVS, with microtia associated with hemifacial skeletal microsomia, vertebral and/or renal malformations. Results. No significant differences were found between the groups when the following variables were compared: gender; prescence of unilateral or bilateral microtia; atretic external auditory canal; presence of preauricelar tags; hearing loss of any type, and affection of the seventh cranial nerve, as well as associated malformations of other otgans or systems. There were significant differences in relation to the presence of soft-tissue hemifacial microsomia, more frequently seen in patients with OAVS, because the majority of these patients had bone microsomia. Over 66 percent of the cases were sporadic and the rest were familiar. In 28.3 percent of the cases, the history suggested an autosomal-dominant inheritance pattern, and in 5.5 percent, an autosomal-recessive inheritance pattent, although in some familial cases, multifactorial inheritance could not be ignored . Some members in several familes has isolated microtia, and others had mild characteristic manifestations of OAVS. Conclusions. Our results support the hypothesis that isolated microtia is a minimal expression of OAVS. Therefore, it is recommended that patients with microtia be subjected to intentional studies that search for malformations and physical examinations of firstdegree relatives for adquate genetic counseling and management
