Resultados da correção da sindactilia na mão com a técnica de Skoog / Results of the correction of syndactyly of the hand by using Skoog's technique

Introdução: A sindactilia é uma anomalia congênita comum da mão, tem incidência de aproximadamente um em 2.000 nascimentos, predomínio no sexo masculino e é bilateral em 50% dos casos. Objetivo é descrever uma série de casos de pacientes com sindactilia nas mãos, operados no Hospital Sarah Brasília, com a técnica de Skoog modificada e o uso de órtese. Métodos: Realizou-se a técnica de Skoog modificada para correção de sindactilia. No pós-operatório, foi confeccionada órtese punho-mão e dedos, e procedeu-se à avaliação do resultado da cicatriz conforme a Escala de Vancouver. Resultado: Durante cinco anos, avaliaram-se 45 pacientes, sendo 30 (66%) homens e 15 mulheres, com idade de um a quatro anos (média de dois anos - 60%), 37% dos casos mostraram-se associados a síndromes, 50% eram simples e bilateral. As complicações observadas nas sindactilias simples foram encontradas em 8% dos pacientes e caracterizaram-se por retração cicatricial, cicatriz visível e alteração ungueal; três casos (6%) foram reoperados para liberação de retração cicatricial com zetaplastia e confecção de neocomissura e quatro casos demandaram realinhamento digital, observado nas sindactilias complexas. Conclusão: Com esta técnica, obtiveram-se 92% de resultados funcionais, 8% de complicações relacionadas à técnica cirúrgica e três reoperações para liberação de retração cicatricial, por meio de zetaplastia e aprofundamento da comissura com novo retalho e enxerto de pele Em relação à avaliação quanto à Escala de Vancouver, o item predominante foi a pigmentação existente entre os dedos devido ao enxerto de pele.

Introduction: Syndactyly is a congenital anomaly of the hand, occurring in approximately 1 in every 2000 births. It is more common in male patients and is present in both hands in 50% of the cases. The objective of this study was to describe a series of cases of patients with hand syndactyly, operated at the Sarah Hospital in Brasília using modified Skoog's technique and orthosis. Methods: The modified Skoog's technique was performed to correct syndactyly. Wrist-hand and finger orthosis was applied postoperatively, and the appearance of the scar was assessed according to the Vancouver Scar Scale. Results: Forty-five patients were assessed during five years, of whom 30 (66%) were male and 15 were female, all aged between 1 and 4 years (mean age: 2 years [60%]); 37% of cases were associated with syndromes and 50% were simple bilateral cases. Complications observed in simple syndactyly occurred in 8% of patients and included scar retraction, visible scars, and ungual changes; three patients (6%) underwent revision surgery with z-plasty and confection of a new web space commissure to correct scar retraction, and four patients required finger realignment, observed in complex syndactyly. Conclusion: This technique resulted in 92% good functional outcomes, 8% complications associated with the surgical technique, and three revision procedures with z-plasty and confection of the web space commissure with a new flap and skin graft to correct scar retraction. The Vancouver scale was used to assess scar quality, and pigmentation between the fingers (due to skin graft) had the highest score.

Complex toe syndactyly with characteristic facial phenotype: a new syndrome?

Nonsyndromic syndactyly is a common, heterogeneous hereditary condition of webbed fingers and toes that can be cutaneous or bony, unilateral or bilateral. We describe a patient with complex toe syndactyly and oligodactyly, some interesting skeletal hand findings and atypical facial features without other case like this described before. Cenani-Lenz syndrome (CLS) is a rare disorder with total syndactyly and irregular synostosis of carpal, metacarpal and phalanges, it may involve ulna and radius and digital rays may be absent, some of these were described with atypical facial features and one patient had renal hypoplasia and vertebral anomalies but our patient does not have the oligodactyly or syndactyly of the hands that is consistently present in all patients with CLS. The atypical facial features of our patient resemble Kabuki syndrome but oligodactyly and complex syndactyly have not been described in Kabuki syndrome and this patient has normal intelligence, and extreme eyelid defect (resembling ablepharon). Therefore, for our patient, we suggested to treat in a new condition of limb anomalies and atypical face.

A novel mutation in the GJA1 gene in a family with oculodentodigital dysplasia.

OBJECTIVES: To describe a Brazilian family with oculodentodigital dysplasia (ODDD) and to screen for mutations in the gap junction protein alpha 1 (GJA1) gene in this family. METHODS: Twelve members of a 3-generation family with ODDD underwent screening for mutations of the GJA1 gene and a comprehensive ophthalmic examination. We defined ODDD on the basis of clinical characteristics described in this syndrome (microdontia, caries, enamel hypoplasia, thin nose, and syndactyly) and eye abnormalities such as microphthalmos, iris atrophy, and glaucoma. Direct sequencing of the GJA1 gene was performed using DNA collected from peripheral blood. A control group of 60 healthy individuals underwent evaluation by means of enzyme digestion. RESULTS: Among the 8 members of this family who were characterized as having ODDD, 2 showed chronic angle-closure glaucoma, and 1 had open-angle glaucoma. A new mutation in the GJA1 gene was identified, consisting of a change from proline to histidine at codon 59. This mutation segregated through members with the ODDD phenotype. Analysis of the control group by means of restriction fragment length polymorphism (MvaI enzyme) did not disclose this mutation. CONCLUSION: Our results demonstrate a new mutation (P59H) in the GJ1A gene, identified in a family with ODDD syndrome. Clinical Relevance The presence of different forms of glaucoma in families with ODDD may indicate a new mutation in the GJA1 gene.

Oculodentodigital dysplasia: study of ophthalmological and clinical manifestations in three boys with probably autosomal recessive inheritance.

Oculodentodigital dysplasia (ODDD) is a rare inherited disorder affecting the development of the face, eyes, teeth, and limbs. The majority of cases of ODDD are inherited as an autosomal dominant condition. There are few reports of probable autosomal recessive transmission. Affected patients exhibit a distinctive physiognomy with a narrow nose, hypoplastic alae nasi, and anteverted nostrils, bilateral microphthalmos, and microcornea. Sometimes iris anomalies and secondary glaucoma are present. There are malformations of the distal extremities such as syndactyly. In addition, there are defects in the dental enamel with hypoplasia and yellow discoloration of the teeth. Less common features include hypotrichosis, intracranial calcifications, and conductive deafness secondary to recurrent otitis media. We describe three brothers with ODDD. Their parents are first cousins and present no features of ODDD. These data are in favor of autosomal recessive inheritance and suggest genetic heterogeneity for this entity.

Cleft lip/palate, abnormal ears, ectrodactyly, congenital heart defect, and growth retardation: definition of the acro-cardio-facial syndrome.

We report on a male patient with a constellation of malformations, including cleft lip/palate, abnormal ears, ectrodactyly, congenital heart defect (CHD), and growth retardation. A similar association has been previously reported twice [Richieri-Costa and Orquizas (1987) Rev Brasil Genet X:787-792; Giannotti et al. (1995) J Med Genet 32:72-74], and autosomal recessive inheritance was proposed.

Hipoplasia de tibia, polidactilia y pulgar trifalángico: primera familia descrita en Venezuela / Hypoplasia of tibia polydactyly and triphalangeal thumbs: first family described in Venezuela

Werner en 1915, describió un paciente con las siguientes características: aplasia o hipoplasia bilateral de tibia, polidactilia y ausencia de pulgares. El modo de herencia es autosómico dominante, con expresividad variable. El objetivo de este trabajo es describir una niña en la que se demostró clínica y radiológicamente la presencia de signos compatibles con el diagnóstico de Hipoplasia de Tibia con Polidactilia. El estudio genealógico permite suponer que el gen tiene una expresividad variable, ya que por la línea materna se encontraron malformaciones tales como: sindactilia en manos, implantación proximal de pulgares y tibia vara. Se discuten los aspectos clínicos, radiológicos y genéticos

Neonatal manifestations of congenital dyserythropoietic anemia type I.

Congenital dyserythropoietic anemia type I is a rare inherited bone marrow disorder characterised by macrocytic anemia with pathognomonic morphological ultrastructural features in erythroid precursors. The disease is usually not diagnosed in the neonatal period. In a retrospective study of 31 patients we found that 17 were first seen in the neonatal age with significant anemia (birth hematocrit 0.34 +/- 0.07); 14 of the 17 infants also had early jaundice. Six infants were small for gestational age and two had syndactyly. Although rare, congenital dyserythropoietic anemia type I should be considered in the differential diagnosis of neonatal anemia.
