"Unum digitum":Caracterización clínica y radiológica de la sindactilia. A propósito de una serie de casos / "Unum Digitum": Clinical and Radiological Characterization of Syndactyly. In Relation to a Number of Cases

Resumen La sindactilia es una de las anomalías congénitas más comunes de las extremidades. Consiste en una malformación digital en la que los dedos adyacentes de manos y/o pies están fusionados por una falla en su separación durante el desarrollo gestacional. Esta se puede categorizar como completa hasta la punta de los dedos o incompleta y simple cutánea o compleja con fusión ósea. La forma complicada comprende una alteración importante de la anatomía digital y generalmente es sindrómica. La importancia del diagnóstico y tratamiento oportuno radica en el impacto cosmético y funcional de la mano, siendo la principal herramienta de trabajo del ser humano, y dada su compleja anatomía y función, la que nos diferencia de otras especies, es imperativa la corrección antes de la fase de secuelas, siendo necesario en la gran mayoría de casos el tratamiento quirúrgico.

Abstract Syndactyly is one of the most common congenital anomalies of the extremities. It consists of a digital malformation in which the adjacent fingers and/or toes are fused by a failure to separate them during gestational development. This can be classified as complete up to the fingertips or incomplete and simple cutaneous or complex with bony fusion. The complicated form involves a significant alteration of the digital anatomy and is usually syndromic. The importance of timely diagnosis and treatment lies in the cosmetic and functional impact of the hand, being the main working tool of the human being, and given its complex anatomy and function, which differentiates us from other species, it is imperative the correction before the sequelae phase, being necessary in the vast majority of cases surgical treatment.

A novel homozygous nonsense mutation in NECTIN4 gene in a Pakistani family with ectodermal dysplasia syndactyly syndrome 1

Abstract Background Ectodermal dysplasia syndactyly syndrome 1 (EDSS1) is a rare hereditary disorder characterized by defects in teeth, hair, and nails in association with a fusion of the digits. Genetically, the disease phenotypes are caused by homozygous and compound heterozygous variants in NECTIN4 gene. Objective The main objective of the study was to identify the pathogenic sequence variant(s) for family screening and identification of carriers. Methods In the present study, the authors have investigated a large consanguineous family of Pakistani origin segregating autosomal recessive EDSS1. All the coding exons of the NECTIN4 gene were directly sequenced using gene-specific primers. Results The affected individuals presented the classical EDSS1 clinical features including sparse hair, hypoplastic nails with thick flat discolored nail plates, peg-shaped, conical, and widely spaced teeth with enamel hypoplasia, proximal cutaneous syndactyly of fingers and toes. Sequence analysis of the coding region of the NECTIN4 identified a novel nonsense variant [c.163C>T; p.(Arg55*)] in exon-2 of the gene. Computational analysis of protein structure revealed that the variant induced premature termination at Arg55 located in Ig-like V-loop region leading to loss of Ig-C2 type domains and transmembrane region, and most likely Nectin-4 function will be lost. Study limitation Gene expression studies are absent that would have strengthened the findings of computational analysis. Conclusion The present study expanded the phenotypic and mutation spectrum of the NECTIN4 gene. Further, the study would assist in carrier testing and prenatal diagnosis of the affected families.

Clinical features and orbital anomalies in Fraser syndrome and a review of management options

Purpose: Fraser syndrome is a rare congenital disorder comprising cryptophthalmos, syndactyly, and many times, urogenital anomalies. Herein, the authors aimed to study and report the clinical features and orbital anomalies in cases diagnosed with Fraser syndrome. Methods: The authors retrospectively evaluated the records of patients with Fraser syndrome who had presented to a tertiary eye care hospital in northern India in the last 2 years (from January 2019 to December 2020). The clinical features were studied, entered in MS Excel, and the data was evaluated. Results: Data of 15 patients with Fraser syndrome were found. Majority of the patients were males and presented in the pediatric age group. Bilateral involvement was more common, and the most common variant of cryptophthalmos was abortive. Complete and medial madarosis of the eyebrows was the most common periocular finding. Complete cryptophthalmos was associated with cystic globes, whereas abortive forms had superior symblepharon. Common systemic features included syndactyly, bifid nose, and urogenital anomaly. Conclusion: Fraser syndrome is an extremely rare developmental disorder; it encompasses a wide range of ocular, periocular, and orbital anomalies, along with multiple pre?existing systemic anomalies. The treating ophthalmologist should always be careful in examining these patients

Tessier cranio-facial clefts presenting to a tertiary eye care center in Northern India: Ophthalmic features and a review of management

Purpose: Tessier classification is used to classify congenital facial cleft disorders utilizing the anatomical location of the cleft and its extension. The orbital and ocular morbidities associated with the birth disorder are numerous. The authors decided to perform a retrospective analysis of the clinical features of the patients who presented to a tertiary care hospital with orbito?cranial clefts. Methods: The authors retrospectively evaluated the records of patients with craniofacial clefts who had presented to a tertiary eye care hospital in northern India in the last 2 years (January 2019–December 2020). The clinical features were studied, entered in MS Excel, and the data were evaluated. Results: The data of 40 patients with Tessier cleft were found. The majority of the patients were male and presented in the pediatric age group. Unilateral involvement was more common, with maxillary hypoplasia being the most common facial anomaly associated. Eyelid coloboma and euryblepharon was the most common periocular finding; lateral epibulbar dermoid and corneal opacity were the most common ocular surface anomaly. The majority of patients had presented for cosmetic correction. The syndromic association was with Goldenhar syndrome (n = 13), Fraser (n = 2), and one each of Treacher Collins, blepharocheilodontic, organoid nevus, and oculo?dento?digital syndrome. Combined clefts were also seen. Conclusion: Tessier cleft classification is a useful tool to classify cranio?facial left anomalies. Multitudes of ocular and orbital anomalies can be associated with their different forms. Better knowledge and understanding of the classification will aid immensely in predicting the ocular defects and planning their management

Aborted Sudden Death Due to Severe Ventricular Arrhythmia in Timothy Syndrome

Abstract Timothy Syndrome is a rare autosomal dominant multisystem genetic condition. The CACNA1C gene, codifier of the CaV1.2 calcium channel, is affected, resulting in the loss of voltage-dependent calcium channel inactivation. Relevant clinical characteristics: (1) corrected QT interval greater than 480ms; (2) syndactyly. Death often occurs during childhood, and results from ventricular tachyarrhythmias. This study presents the case of a female newborn who suffered a cardiorespiratory arrest, secondary to ventricular arrhythmia. A prolonged QT interval, combined with 2:1 AV block, was also identified, requiring a definitive cardiac pacemaker implant that, during inpatient care, developed pulmonary sepsis, followed by death.

Monitoring of birth defects in perinatal infants born during 2015-2019 in Huainan City, Anhui Province / 中国基层医药

Objective:To analyze birth defects in perinatal infants in Huainan city, Anhui province.Methods:The data of perinatal infants with birth defects born during 2015-2019 who were monitored in nine national and provincial birth defect monitoring hospitals in Huainan City were collected. The changes in birth defects, the incidence of birth defects in infants ≥ 28 weeks, urban and rural area distribution of birth defects, type of defects, and the related factors of birth defects during a 5-year study period were analyzed.Results:A total of 90 466 perinatal infants with the incidence of birth defects of 89.87/10 000 were monitored during 2015-2019. The incidence of birth defects in Anhui Province was 139.74/10 000. The proportion of preterm infants < 28 weeks with birth defects among full-term births with birth defects was 30.93% and the proportion increased year by year during 2015-2019, with the proportion of 14.84%, 31.69%, 34.83%, 32.84% and 34.02% respectively. The top five birth defects detected during 2015-2019 were multiple fingers (toes) ( n = 189, 20.89/10 000), cleft lip ( n = 96, 10.61/10 000), external ear deformity ( n = 79, 8.73/10 000), congenital heart disease ( n = 65, 7.19/10 000) and syndactyly ( n = 40, 4.42/10 000). The incidence of birth defects in males and females was 102.77/10 000 and 85.28/10 000, respectively. The incidence of birth defects in urban and rural areas were 107.38/10 000 and 79.60/10 000, respectively. Conclusion:The incidence of birth defects in preterm infants < 28 weeks in Huainan City was lower than that in the whole Anhui Province. The incidence of birth defects in Huainan City differed in different years. The incidence of birth defects in males was higher than that in females. From 2016, the incidence of birth defects in urban area was higher than that in rural area. Birth defects mainly consisted of multiple fingers (toes), external ear deformity, congenital heart disease, cleft lip and syndactyly. The detection rate of birth defects in preterm (< 28 weeks) patients was increased year by year. Early intervention effectively decreased the incidence of birth defects and improved the quality of the population in Huainan City.

Lethal and semi-lethal mutations in Holstein calves in Uruguay / Mutações letais e semi-letais em bezerros da raça Holandesa no Uruguai

ABSTRACT: Genetic disorders in Holstein cattle are a health problem that has grown worldwide in recent years, compromising the sustainability of modern dairy production. In Uruguay, Holstein-based milk production is one of the most important sectors of the country's economy, but high levels of inbreeding have decreased the breed's fertility in recent decades. This study investigated the presence and diffusion of lethal and semi-lethal alleles causing embryo death, abortions, fetal malformations, and neonatal diseases in Holstein calves. Using the GeneSeek® Genomic Profiler™ Bovine 50K BeadChip, we genotyped 383 calves (1-30 days-old) from 27 farms located in the main dairy region of Uruguay. Results showed a high prevalence of farms (85%) and carrier calves (21%), including one or more of the following semi-lethal or lethal alleles: Syndactylism (4.18%), brachyspina (3.39%), cholesterol deficiency haplotype (2.61%), complex vertebral malformation (2.09%), bovine leukocyte adhesion deficiency (1.04%s), and Holstein haplotypes HH1 (4.44%), HH3 (3.13%), HH4 (1.04%), and HH5 (0.26%). Most of these alleles had not been recognized previously in Uruguay. We concluded that lethal and semi-lethal mutations are widespread in the Holstein breed in Uruguay. More studies are required to determine their impact on dairy cattle fertility.

RESUMO: Os distúrbios genéticos nos bovinos da raça Holandesa são um problema de saúde que cresceu nos últimos anos a nível mundial, comprometendo a sustentabilidade da produção leiteira moderna. No Uruguai, a produção leiteira com base na raça Holstein é um dos setores mais importantes da economia do país, mas altos níveis de endogamia diminuíram a fertilidade da raça nas últimas décadas. O objetivo deste estudo foi investigar a presença e difusão de alelos letais e semi-letais causando morte de embriões, abortos, malformações fetais e doenças neonatais em bezerros da raça Holandesa. Usando o BeadChip Bovino 50K GeneSeek® Genomic Profiler™, genotipamos 383 bezerros (menos de um mês) de 27 fazendas localizadas na principal região leiteira do Uruguai. Os resultados mostraram uma alta prevalência de fazendas (85%) e bezerros portadores (21%), incluindo um ou mais dos seguintes alelos letais ou semi-letais: sindactilismo (4,18%), braquipespina (3,39%), haplótipo de deficiência de colesterol (2,61%), malformação vertebral complexa (2,09%), deficiência de adesão de leucócitos bovinos (1,04% s) e haplótipos de Holstein HH1 (4,44%), HH3 (3,13%), HH4 (1,04%) e HH5 (0,26%). A maioria desses alelos não havia sido reconhecida anteriormente no país. Concluímos que as mutações letais e semi-letais são comuns na raça Holstein no Uruguai. Mais estudos são necessários para determinar seu impacto na fertilidade do gado leiteiro.

Xantoma tendinoso normolipémico múltiple en coexistencia con glaucoma terminal bilateral y sindactilia / Multiple normolipemic tendinous xanthoma in coexistence with bilateral terminal glaucoma and syndactyly

RESUMEN Los xantomas tendinosos están habitualmente asociados con hiperlipidemia, de ahí que son infrecuentes los xantomas tendinosos normolipémicos. La histopatología de este cuadro es característica por la presencia de células espumosas, hendiduras de colesterol y células de Touton. Presentamos el caso de un paciente varón de 22 años portador de xantomas tendinosos normolipémicos, en coexistencia con glaucoma terminal bilateral y sindactilia donde la histología y la inmunohistoquímica fueron de gran utilidad para el diagnóstico definitivo.

ABSTRACT Tendinous xanthomas are usually associated with hyperlipidemia, normolipemic tendinous xanthomas are uncommon. The histopathology of this condition is characterized by the presence of foam cells, cholesterol clefts, and Touton cells. We present a 22-year-old male patient with normolipemic tendon xanthomas, coexisting with bilateral terminal glaucoma and syndactyly, where histology and immunohistochemistry were very useful to reach the definitive diagnosis.

A case of polymelia associated with syndactyly in Didelphis aurita (Wied-Neuwied, 1826) / Relato de caso de polimelia associada a sindactilia em Didelphis aurita (Wied-Neuwied, 1826)

Abstract In January 2018, a young male of Didelphis aurita (Wied-Neuwied, 1826), the Brazilian common opossum, was admitted for veterinary evaluation at the Recovery Clinic of Wild Animals of Estácio de Sá University, CRAS, in Rio de Janeiro, Brazil, due to the presence of a partially duplicated right hind limb. After x-ray evaluation, polymelia associated with syndactyly was diagnosed. The images revealed the following alterations on the right limb: single femur with increased diameter, two tibiae, two fibulae and absence of hallux. The observed malformations were restricted to the hind right limb, which remains functional. This is the first report of such anomalies in an individual of Didelphis aurita.

Resumo Em janeiro de 2018, um macho jovem de Didelphis aurita (Wied-Neuwied, 1826), o gambá-de-orelha-preta, foi recebido para atendimento veterinário na Clínica de Recuperação de Animais Silvestres (CRAS) da Universidade Estácio de Sá, no Rio de Janeiro, por ser portador de membro posterior direito parcialmente duplicado. Após exame radiográfico, constatou-se a ocorrência de polimelia associada a sindactilia. As imagens radiográficas revelaram as seguintes alterações no membro posterior direito: um fêmur com diâmetro aumentado, duas tíbias, duas fíbulas e ausência de hálux. As malformações observadas restringiram-se apenas ao membro posterior direito, o qual mantém sua funcionalidade. Essas alterações nunca antes foram descritas na espécie Didelphis aurita.

Objetivo: Ilustrar la importancia del diagnóstico prenatal del síndrome de Apert como elemento esencial para la atención multidisciplinaria posnatal del futuro niño. Reporte de caso: Se presenta un neonato de sexo masculino, nacido a las 39 semanas de gestación por parto eutócico, con signos de craneosinostosis y sindactilia en las manos y los pies por lo que se le realizó el diagnóstico posnatal de síndrome de Apert. Conclusiones: Los pacientes con el síndrome de Apert deben ser diagnosticados oportunamente durante la pesquisa prenatal, considerando el conjunto de sus signos y alteraciones y no como anomalías aisladas, como puede ocurrir de realizarse el diagnóstico en el período posnatal. De efectuarse el diagnóstico prenatal se lograría el tratamiento de forma multidisciplinaria y se podría garantizar al paciente una calidad de vida superior.

ABSTRACT Background: Apert syndrome consists of a genetic disease with craniofacial anomaly called acrocephalosyndactyly; it produces malformations in the skull such as craniosynostoses, in addition to alterations in the face, hands and feet, it can be inherited, secondary to sporadic mutations of the FGFR2 gene and some other genes. Due to genetic screening programs, the prenatal diagnosis of this syndrome enables genetic counseling and multidisciplinary medical assistance. Objective: To illustrate the importance of prenatal diagnosis of Apert syndrome as an essential element for the postnatal multidisciplinary care of the future child. Case report: A male neonate, born at 39 weeks of gestation by eutocic delivery, with signs of craniosynostoses and syndactyly on the hands and feet, so he was made the postnatal diagnosis of Apert syndrome. Conclusions: Patients with Apert syndrome should be diagnosed appropriately in time during prenatal screening, considering all their signs and alterations and not as isolated abnormalities, as may occur if the diagnosis is made in the postnatal period. If the prenatal diagnosis was made, the treatment would be achieved in a multidisciplinary way and a better quality of life could be guaranteed to the patient.

Reconstruction finger web with dorsal two wing-shaped advancement flap for the treatment of congenital syndactyly / 中国修复重建外科杂志

Objective: To discuss the effectiveness of using dorsal two wing-shaped advancement flap to reconstruct finger web for treatment of congenital syndactyly. Methods: Between August 2014 and August 2017, 30 cases of congenital syndactyly were treated, including 18 males and 12 females with an average age of 2.5 years (range, 1.5-5 years). Eight cases were of bilateral hands syndactyly and 22 cases of single hand syndactyly. There were 39 webs of syndactyly (including 1 case of syndactyly of middle finger, ring finger, and little finger). Among them, 11 webs were complete and 28 webs were incomplete. At the dorsum, a flap with V-shaped tip and two wing-shaped pedicle was designed and was just sewed up with an anchor-shaped incision at the palm. Distal end of fingers were separated by serrated flap and were sutured after removal of fatty tissue. In 11 cases with tight skin connection, the defect area at lateral and distal end of fingers was repaired by small pieces of full-thickness skin graft. Results: All the flaps survived completely after operation, and no flap necrosis occurred. The skin grafts on the distal side of the finger survived and the wound healed by first intension. All 30 cases were followed up 6-12 months, with an average of 9 months. Postoperative flexion and extension function of fingers were good, and the web depth and width were normal. At last follow-up, according to the Swanson et al. standard, 20 fingers were graded as excellent, 8 as good, and 2 as fair, with an excellent and good rate of 93.3%. Conclusion: The effectiveness of using dorsal two wing-shaped advancement flap to reconstruction finger web for treatment of congenital syndactyly is satisfactory.

Objective: To observe vessels of hand for congenital syndactyly malformation (CSM) in children with contrast-enhanced three-dimensional water selective cartilage scan (CE-3D-WATSc). Methods Twelve children with CSM underwent CE-3D-WATSc before separation surgery of syndactyly were included. The bifurcated positions of common palmar digital arteries, the development and trend of proper palmar digital arteries were observed. The consequences of CE-3D-WATSc and intraoperative observation were compared and analyzed. Results: The common palmar digital arteries of hands in 12 cases were shown with CE-3D-WATSc, of which the bifurcated positions were normal in 10 cases and were slightly elevated to about 1/3 of proximal phalanges in 2 cases, which were completely consistent with the intraoperative observation results.The proper palmar digital arteries were displayed with CE-3D-WATSc in 10 cases, among which 9 were normal development and 1 was small, while not shown in 2 cases. During surgical operation, the proper palmar digital arteries were found in 12 cases, while being filamentous in 2 cases that not shown with CE-3D-WATSc. Conclusion: CE-3D-WATSc has some application values in evaluating vessels of hand for CSM in children before surgical operation.

Background Syndactyly is one of the inherited malformations that most often involve the hands. It is a frequent cause of surgical intervention, with few literature reports as regards follow-up and outcomes. The objective of the study is to evaluate the functional and aesthetic results after the surgical management of syndactyly release from the hands of children diagnosed with congenital syndactyly. Materials and methods A series of cases was conducted that included patients under the age of 15 who attended an orthopaedic clinic with a diagnosis of congenital syndactyly. All patients were subjected to surgery to release the congenital defect. All patients underwent post-operative follow-up for at least 3 months. Results The study included 15 patients aged 0-15 years, 73.3% of whom were male. The 53.3% of the patients with good functional results, were operated on using the reconstructive technique of the dorsal-palmar rectangular flap, with 45.4% requiring a skin graft. Twenty percent of the patients had both good postoperative functional and aesthetic results, with no complications and with no re-interventions in the 3 months postoperative follow-up. Discussion Almost three-quarters (73.3%) of the patients showed good aesthetic results, and 60% had good functionality,when evaluating the mobility arches. Early intervention was related to a decrease in the number of complications and a lower number of re-interventions. Level of evidence IV.
