Manejo odontológico de una paciente con síndrome de Apert / Dental management of a patient with Apert syndrome

El síndrome de Apert, marcado por la acrocéfalo-sindactilia, es una condición genética que genera deformidades dentofaciales incluyendo craneosinostosis, alteraciones faciales y malformaciones en extremidades. La mutación en el gen FGFR2, ya sea heredada o resultante de mutaciones esporádicas, desencadena esta compleja condición. La relevancia de abordar el síndrome de Apert se manifiesta no sólo en las implicaciones estéticas, sino también en su impacto en la salud oral. Romper con los paradigmas odontológicos actuales implica reconocer las particularidades de estos pacientes y proporcionar una atención especializada. La necesidad de una capacitación específica para los profesionales de la salud oral es evidente, permitiendo un enfoque integral que aborde la prevención y el tratamiento de las malformaciones craneofaciales asociadas. Superar los desafíos tradicionales implica adoptar una perspectiva inclusiva y personalizada en la atención odontológica. Esto no sólo mejora la calidad de vida de los pacientes con síndrome de Apert, sino que también destaca la importancia de una atención adaptada que trascienda los límites convencionales, ofreciendo soluciones innovadoras para las complejidades bucodentales asociadas a esta condición genética (AU)

Apert syndrome, marked by acrocephalosyndactyly, is a genetic condition that generates dentofacial deformities, including craniosynostosis, facial alterations and limb malformations. Mutation in the FGFR2 gene, whether inherited or resulting from sporadic mutations, triggers this complex condition. The relevance of addressing Apert syndrome is manifested not only in the aesthetic implications, but also in its impact on oral health. Breaking with current dental paradigms involves recognizing the particularities of these patients and providing specialized care. The need for specific training for dental health professionals is evident, allowing a comprehensive approach that addresses the prevention and treatment of associated craniofacial malformations. Overcoming traditional challenges means taking an inclusive and personalized perspective on dental care. This not only improves the quality of life of patients with Apert syndrome, but also highlights the importance of tailored care that transcends conventional boundaries, offering innovative solutions for the oral complexities associated with this genetic conditio (AU)

Apert syndrome: neurosurgical outcomes and complications following posterior vault distraction osteogenesis.

PURPOSE: Posterior vault distraction osteogenesis (PVDO) has been utilized during the past 15 years to treat a variety of clinical features commonly presented by patients with Apert syndrome. The objective of this study is to determine the efficacy of PVDO in addressing both elevated intracranial pressure (ICP) and ectopia of the cerebellar tonsils (ECT) in young Apert patients. In addition, we aimed to determine the prevalence of hydrocephalus in Apert syndrome patients who underwent PVDO. METHODS: A retrospective study was made with a cohort of 40 consecutive patients with syndromic craniosynostosis (SC), previously diagnosed with Apert syndrome, who underwent PVDO between 2012 and 2022, and thereafter received at least 1 year of follow-up care. Demographic data and diagnosis, along with surgical and outcome data, were verified using medical records, clinical photographs, radiologic examination, and interviews with the parents of all cohort patients. RESULTS: The average patient age when PVDO was performed was 12.91 ± 10 months. The average posterior advancement distance achieved per patient was 22.68 ± 5.26 mm. The average hospital stay per patient was 3.56 ± 2.44 days. The average absolute and relative blood transfusion volumes were 98.47 ml and 17.63 ml/kg, respectively. Although five patients (14%) presented ECT preoperatively, this condition was completely resolved by PVDO in three of these five patients. One of the three patients whose ECT had completely resolved presented syringomyelia postoperatively, requiring subsequent extra dural foramen magnum decompression. All of the remaining four patients were asymptomatic for ECT for at least 1 year of follow-up, and none of these four patients required any additional treatments to address ECT. Two patients presented hydrocephalus requiring ventriculoperitoneal shunt placement. CONCLUSIONS: This study demonstrates that PVDO both reduces diagnosed elevated ICP symptoms and is partially effective in treating ECT in Apert syndrome patients. Hydrocephalus in Apert syndrome is an uncommon feature. The effectiveness of PVDO in addressing hydrocephalus is uncertain.

Apert Syndrome: Selection Rationale for Midface Advancement Technique.

Apert syndrome is characterized by a wide spectrum of craniofacial clinical features that have been successfully addressed via a variety of midface advancement techniques. Although surgeons have individual preferences as to which specific procedures should be performed to best treat Apert patients, craniofacial plastic surgeons, working in tandem with pediatric neurosurgeons, can identify and evaluate functional limitations and facial morphologic disproportions, and establish appropriate criteria for effective midface advancement technique indication and selection. The purpose of this review article is to present and discuss our rationale for midface advancement technique selection based upon the most common craniofacial characteristics presented by Apert syndrome patients. The present article also provides a grading system that stratifies as major, moderate, and mild, the effect of each midface advancement technique on the different types of Apert syndrome facial features. Surgeons should take into consideration the maximum effect and benefit of each craniofacial osteotomy and how these procedures will alter the craniofacial skeleton. By understanding the long-term effect of each osteotomy on the most common craniofacial characteristics of Apert syndrome patients, craniofacial plastic surgeons and neurosurgeons will be able to customize the surgical procedures they perform in order to achieve the best possible outcomes.

Métodos de avaliação cognitiva de pacientes com Síndrome de Apert e de Crouzon / Cognitive assessment methods of patients with Apert and Crouzon syndrome

A Craniossinostose Coronal bilateral implica em diminuição do Perímetro Craniano (PC) no eixo ântero-posterior (Braquicefalia) e frequentemente se associa ao aumento do eixo céfalo-caudal (vertical-altura) do crânio (Turricefalia), sendo um dos achados mais comuns nas Síndromes de Crouzon e Apert. Objetivo: Identificar, analisar e sintetizar os métodos de avaliação cognitiva apropriados para o acompanhamento da evolução de pacientes com cranioestenoses sindrômicas, em particular as síndromes de Apert e de Crouzon. Método: Trata-se de uma revisão de escopo. Para a formulação da pergunta norteadora da pesquisa e da estratégia de busca, foi utilizada a estratégia Population [((Apert OR Crouzon) AND (Disease OR Syndrom*))], Concept [((cognit* OR neurobehavioral OR neurocognit* OR neuropsyc*) AND (evaluation OR evaluations OR assessment OR "test" OR tests OR status OR development OR disorder OR disorders OR impairment OR impairments OR impaired OR function OR functions))] e Context (em qualquer contexto). Foram inclusos os artigos escritos em inglês, português e espanhol em qualquer período. A busca foi realizada nas bases de dados: Embase, Scopus, PubMed/MEDLINE e rede BVS Salud. Resultados:Inúmeros testes de avaliação cognitiva validados internacionalmente foram aplicados aos pacientes com Apert e Crouzon, mas não se observou uma padronização (protocolo) seguida pelas várias unidades de assistência. Dos 75 tipos de Testes Cognitivos aplicados houve o predomínio da Escala de Inteligência de Wechsler (e seus subtestes), 50%. Na população avaliada predominou duas faixas etárias: escolares e adolescentes. As crianças com Apert e Crouzon obtiveram escores piores nos transtornos de socialização, atenção e internalização quando comparadas com o grupo normativo, sendo os piores resultados encontrados em Apert. Fatores que interferem no desenvolvimento neuropsicomotor: pressão intracraniana, malformações encefálicas, genética, idade na correção cirúrgica (postergação da primeira cirurgia após um ano de idade associou-se a um quociente de inteligência mais baixo), institucionalização, ambiente familiar, escolaridade dos cuidadores e nível socioeconômico. Considerações finais: os resultados obtidos contribuíram para maior conhecimento do perfil cognitivo dos pacientes com estas síndromes. Somente conhecendo as habilidades e dificuldades neuropsicomotoras, cognitivas e psicossociais dos pacientes com Apert e Crouzon é que as equipes de saúde, da escola e de cuidadores poderão entender melhor a capacidade perceptiva destes no processo de aprendizado e estarão mais aptas em atender as necessidades especiais destes pacientes e poderão ofertar os estímulos mais adequados no momento mais oportuno (AU).

Bilateral Coronal Craniosynostosis implies a decrease in the Cranial Perimeter (CP) in the anteroposterior axis (Brachycephaly) and is frequently associated with an increase in the cephalocaudal (vertical height) axis of the skull (Turrycephaly); being one of the most common findings in Crouzon and Apert Syndromes (Syndromic Craniosynostosis). In this Scope Review study, among the Syndromic Craniosynostosis, Apert and Crouzon Syndromes will be of special interest. Objective: This study aimed to identify, analyze, and synthesize the appropriate cognitive assessment methods for monitoring the evolution of patients with syndromic craniosynostosis, in particular Apert's and Crouzon's syndromes. Method: This is a scope review. In order to formulate the research guiding question and the searching strategy, the Population [((Apert OR Crouzon) AND (Disease OR Syndrom*))], Concept [((cognit* OR neurobehavioral OR neurocognit* OR neuropsyc*) AND (evaluation OR evaluations OR assessment OR "test" OR tests OR status OR development OR disorder OR disorders OR impairment OR impairments OR impaired OR function OR functions))] and Context (in any context) strategy was used. The articles written in English, Portuguese, and Spanish in any period were included. The search was performed in the following databases: Embase, Scopus, National Library of Medicine (PubMed/MEDLINE), and in the BVS Salud network (PAHO, WHO, BIREME, LILACS). Results: many internationally validated cognitive assessment tests were applied to patients with Apert and Crouzon, but no standardization (protocol) was followed. Of the 75 types of Cognitive Tests applied, the Wechsler Intelligence Scale predominated, 50%. In the evaluated population, two age groups predominated: school children and adolescents. Children with Apert and Crouzon had worse scores on disorders of socialization, attention, and internalization when compared to the normative group, with the worst results found in Apert. Factors that interfere with cognitive development: intracranial pressure, brain malformations, genetics, age at surgical correction, institutionalization, family environment, caregiver education, and socioeconomic status. Conclusion: the results contributed to a better understanding of the cognitive profile of patients with these syndromes and only by knowing about the neuropsychomotor, cognitive, and psychosocial skills and difficulties of these patients with Apert and Crouzon that health, school, and caregiver teams will be able to understand the perceptive capacity in the learning process of these patients deeply and will be able to offer the most appropriate stimuli at the most opportune time. Keywords: Apert, Crouzon, Neuropsyc, Tests, Development (AU).

Métodos: se llevó a cabo una búsqueda en las bases de datos MedLine (PubMed), Science Direct, Scopus y Wiley Online Library con la combinación de los siguientes términos: Syndromic craniosynostosis, Dental treatment, orthodontic treatment, Apert Syndrome, surgical treatment, dental care. Se incluyeron revisiones sistemáticas y de literatura, estudios retrospectivos, longitudinales y de cohorte, series y revisiones de caso publicados entre 1990 y 2020 en español o inglés; se excluyeron artículos relacionados con otros síndromes, así como estudios en animales. Los artículos fueron seleccionados según su pertinencia y disponibilidad de texto completo; hallazgos repetidos fueron eliminados; adicionalmente, se utilizó el sistema bola de nieve en los artículos seleccionados; la calidad de la evidencia fue evaluada mediante el sistema GRADE. Resultados: 34 artículos fueron incluidos (calidad alta: 2, moderada: 1, baja: 19 y muy baja: 12). Entre estos, se identificaron discusiones relacionadas con la etapa de crecimiento a la que se recomienda realizar los procedimientos quirúrgicos requeridos para minimizar sus impactos negativos. La mayoría de los artículos apoyan el manejo terapéutico ejecutado por equipos multidisciplinarios. Conclusiones: un plan de tratamiento combinado de ortodoncia y cirugía ortognática se presentó como la mejor opción para obtener los mejores resultados funcionales y estéticos para la población en cuestión. El momento adecuado durante el crecimiento y desarrollo de los individuos para implementar cada fase de tratamiento fue decidido por cada equipo multidisciplinario.

Objective: Carry out a literature review about the orthodontic and surgical treatments of Apert Syndrome, during the different stages of growth and development. Methods: A search was made in the MedLine (PubMed), Science Direct, Scopus, and Wiley Online Library databases with the combination of the following terms: Syndromic craniosynostosis; Dental treatment; orthodontic treatment; Apert Syndrome; surgical treatment; dental care. Types of the study included: Systematic and literature reviews, retrospective, longitudinal, and cohort studies, series, and case reviews that were published between 1990-2020 in Spanish or English; articles related to other syndromes and animal, or laboratory studies were excluded. The articles were selected according to relevance and availability of full text; repeated findings were eliminated; additionally, the snowball system was used in the selected articles; the quality of the evidence was evaluated using the GRADE system. Results: 34 articles were included (High Quality: 2; Moderate: 1; Low: 19; Very Low: 12). Controversies were found related to the stage of growth to which it is recommended to perform the required surgical procedures to minimize the negative impacts. Most of the articles support therapeutic management by multidisciplinary teams. Conclusions: A combined orthodontic and orthognathic surgery treatment plan was presented as the indicated option to obtain the best possible functional and aesthetic results for the population in question. The appropriate time during the growth and development of individuals to implement each treatment phase was decided by each multidisciplinary team.

Syndrome-related outcomes following posterior vault distraction osteogenesis.

PURPOSE: The most commonly occurring syndromic craniosynostoses are Apert syndrome, Crouzon syndrome, Pfeiffer syndrome, and Saethre-Chotzen syndrome. There is insufficient data regarding postoperative syndrome-related outcomes following the posterior vault distraction osteogenesis (PVDO) procedure, as well as data addressing whether or not additional procedures will be subsequently necessary to comprehensively treat children who undergo PVDO. Thus, the objective of this study is to describe and compare syndrome-related potential complications and outcomes associated with the PVDO procedure. METHODS: An observational retrospective study was performed on consecutive patients (n=24) with Apert syndrome, Crouzon syndrome, Pfeiffer syndrome, or Saethre-Chotzen syndrome, respectively, who underwent PVDO between 2012 and 2019. Demographic data (patient gender and age when the PVDO procedure was performed), diagnosis, surgery-related data, and outcome data (perioperative and midterm complications and need for additional surgery) were verified. RESULTS: Total relative blood transfusion volumes per kilogram for the patients were as follows: 22.75 ± 9.30 ml for Apert syndrome, 10.73 ± 2.28 ml for Crouzon syndrome (Apert versus Crouzon, p<0.05), 18.53 ± 8.08 ml for Pfeiffer syndrome, and 19.74 ± 9.12 ml for Saethre-Chotzen syndrome. None of the patients required a secondary procedure to alleviate intracranial pressure except for a Saethre-Chotzen patient. CONCLUSION: PVDO is an effective technique to address elevated intracranial pressure in SC patients that alleviates the need for secondary procedures at midterm follow-up. Apert syndrome patients presented relatively higher total blood transfusion rates than Crouzon syndrome patients who were operated on at a later age and weighed more.

Clinical and genetic findings of two cases with Apert syndrome / Hallazgos clínicos y genéticos de dos casos con síndrome de Apert

Abstract Background: Craniosynostosis is described as the premature fusion of cranial sutures that belongs to a group of alterations which produce an abnormal phenotype. Case report: Two unrelated female patients with clinical findings of Apert syndrome-characterized by acrocephaly, prominent frontal region, flat occiput, ocular proptosis, hypertelorism, down-slanted palpebral fissures, midfacial hypoplasia, high-arched or cleft palate, short neck, cardiac anomalies and symmetrical syndactyly of the hands and feet-are present. In both patients, a heterozygous missense mutation (c.755C>G, p.Ser252Trp) in the FGFR2 gene was identified. Conclusions: Two cases of Apert syndrome are described. It is important to recognize this uncommon entity through clinical findings, highlight interdisciplinary medical evaluation, and provide timely genetic counseling for the family.

Prenatal diagnosis of Apert syndrome using ultrasound, magnetic resonance imaging, and three-dimensional virtual/physical models: three case series and literature review.

OBJECTIVE: This aimed to describe the prenatal diagnosis of three cases of Apert syndrome using two-dimensional (2D) and three-dimensional (3D) ultrasound, magnetic resonance imaging (MRI), and 3D virtual/physical models. METHODS: We retrospectively analyzed three cases of Apert syndrome at our service. The prenatal diagnostic methods used were 2D ultrasound, 3D ultrasound in conventional and HDlive rendering modes, T2-weighted MRI sequences, and 3D virtual/physical models from MRI or 3D ultrasound scan data. All imaging methods were performed by one observer. All prenatal diagnoses were confirmed by autopsy in cases of termination of pregnancy or genetic assessment during the postnatal period. RESULTS: Mean ± standard deviation of maternal and gestational age at the time of diagnosis was 36.5 ± 3.5 years and 32 ± 4.2 weeks, respectively. Main 2D/3D ultrasound and MRI findings were craniosynostosis, hypertelorism, low ear implantation, increased kidneys dimensions, and syndactyly of hands and feet. 3D virtual/physical models allowed 3D view of fetal head and extremity abnormalities. Termination of pregnancy occurred in two cases. CONCLUSION: Prenatal 3D ultrasound and MRI enabled the identification of all Apert syndrome phenotypes. 3D virtual/physical models provided both the parents and the medical team a better understanding of fetal abnormalities.

Diagnóstico y evolución de un paciente con acrocefalosindactilia tipo I o síndrome de Apert / Diagnosis and progress of a patient with type 1 acrocephalosyndactyly or Aperts syndrome

El síndrome de Apert es una afección genética que constituye una rareza médica, dada su escasa frecuencia; se caracteriza por craneosinostosis congénita, sindactilia de las manos y de los pies, anquilosis diversas y sinostosis progresiva de las manos, los pies y la columna vertebral, además de diversas alteraciones funcionales que varían mucho de un enfermo a otro. Su prevalencia se estima de 1 en 65 mil, aproximadamente, 15,5 por cada 1 millón de nacidos vivos. Se presenta el caso de una niña con las características clínicas de un síndrome de Apert, diagnosticada antes del año de edad y evolucionada hasta la actualidad. Intervenida quirúrgicamente en tres ocasiones de ambas manos por la sindactilia bilateral, rehabilitada con resultados satisfactorios. A los siete años muestra maloclusión dentaria y afectación de la visión, pendiente de cirugía en los pies por la sindactilia. Tiene dificultad para la marcha y falta de equilibrio(AU)

Aperts syndrome is a rare genetic condition because of its small frequency and is characterized by congenital craniosynostosis, syndactyly of the hands and feet, several ankylosis and progressive synostosis of the hands, feet and spine, as well as several functional alterations that vary greatly from one patient to another. Its prevalence is estimated to be 1 in 65,000, approximately 15,5 per 1,000,000 live births. This study presents the case of a girl with the clinical characteristics of Aperts syndrome, who was diagnosed before the year of age and who has been followed-up to the present. The patient was surgically operated on both hands three times due to bilateral syndactyly and has been rehabilitated with satisfactory results. At the age of seven she presented dental malocclusion and vision impairment. The patient is waiting for surgery on the feet due to syndactyly. She has difficulty walking and lack of balance(AU)

Manifestações bucais da síndrome de apert: relato de caso clínico / Expressions of oral apert syndrome: clinical case report

A Síndrome de Apert, também chamada de acrocefalossindactilia tipo 1, é caracterizada pelo encerramento prematuro das suturas cranianas (craniossinostose), sindactilia simétrica das mãos e dos pés e anomalias faciais. Outras anormalidades observadas são atraso mental, anquilose articular e anomalias da coluna vertebral. Destacam-se, ainda, a hipoplasia da face média com Classe III, lábios hipotônicos, úvula bífida, erupção ectópica, má oclusão e pseudofenda palatina. A cavidade bucal desses pacientes apresenta normalmente uma redução no tamanho da maxila, em particular na direção anteroposterior. Essa redução pode resultar em apinhamento dentário e uma mordida aberta anterior. A mandíbula está dentro do tamanho e da forma normal, e simula um pseudoprognatismo. Anomalias dentárias, tais como dentes inclusos, erupção retardada, agenesia dentária, hipoplasia do esmalte, dentes ectópicos ou supranumerários são comumente observadas. Diante da necessidade de um tratamento multidisciplinar e da relevância do cirurgião-dentista no acompanhamento desses pacientes, o objetivo deste relato é descrever as manifestações bucais da síndrome, enfatizando as características mais frequentes no período de transição da dentição decídua para a dentição permanente.

Apert syndrome, also called acrocephalosyndactyly type 1, is characterized by the premature closure of the cranial sutures (craniosynostosis), symmetric syndactyly of the hands and feet and facial anomalies of the midline. People with Aper syndrome have craniofacial abnormalities as exophthalmos, ocular hy-pertelorism, broad and short nose with a bulbous tip. The patients have hypoplasia midface with Class III, hypotonic lips, cleft uvula, ectopic eruption, malocclusion and pseudo cleft palate. The oral cavity usually these patients showed a reduction in the size of the jaw, in particular in the rearward direction. This reduc¬tion may result in tooth crowding and in an anterior open bite. The jaw size is within the normal way and simulates a pseudoprognathism. Dental anomalies, such as impacted teeth, delayed eruption, tooth agenesis, enamel hypoplasia, ectopic or supernumerary teeth are commonly observed. Given the need for a multidis¬ciplinary approach and the relevance of the dentist in monitoring these patients, the objective of this report is to describe the oral manifestations of the syndrome emphasizing the most common features in the transition period of the deciduous dentition to the permanent dentition.

Molecular analysis of exons 8, 9 and 10 of the fibroblast growth factor receptor 2 (FGFR2) gene in two families with index cases of Apert Syndrome.

INTRODUCTION: Apert syndrome (AS) is a craniosynostosis condition caused by mutations in the Fibroblast Growth Factor Receptor 2 (FGFR2) gene. Clinical features include cutaneous and osseous symmetric syndactily in hands and feet, with variable presentations in bones, brain, skin and other internal organs. METHODS: Members of two families with an index case of Apert Syndrome were assessed to describe relevant clinical features and molecular analysis (sequencing and amplification) of exons 8, 9 and 10 of FGFR2 gen. RESULTS: Family 1 consists of the mother, the index case and half -brother who has a cleft lip and palate. In this family we found a single FGFR2 mutation, S252W, in the sequence of exon 8. Although mutations were not found in the study of the patient affected with cleft lip and palate, it is known that these diseases share signaling pathways, allowing suspected alterations in shared genes. In the patient of family 2, we found a sequence variant T78.501A located near the splicing site, which could interfere in this process, and consequently with the protein function.

INTRODUCCIÓN: El síndrome Apert (SA) es un síndrome que cursa con craneosinostosis el cual es ocasionado por mutaciones en el gen del Receptor 2 del Factor de Crecimiento de Fibroblastos (FGFR2). Se caracteriza clínicamente por presentar sindactilias cutáneas y óseas en manos y pies de forma simétrica, cursa además con manifestaciones variables esqueléticas, cerebrales, en piel y otros órganos internos. MÉTODOS: Miembros de dos familias con caso índice de Síndrome Apert fueron evaluados con el objetivo de describir las características clínicas relevantes y el análisis molecular (secuenciación y amplificación) de los exones 8, 9 y 10 del gen FGFR2. RESULTADOS: La familia 1 está constituida por la madre, el caso índice y un medio hermano que presenta labio y paladar hendido. En esta familia solo se encontró la mutación S252W en la secuencia del exón 8 del gen FGFR2 del caso índice. A pesar no encontrarse mutaciones dentro del estudio realizado al paciente afectado con labio y paladar hendido, se conoce que estas patologías comparten vías de señalización, lo que permite sospechar alteraciones en genes compartidos. En la familia 2, el resultado molecular del caso índice reportó la variante T78.501A en la secuencia del intrón 8, la cual se sitúa cercana al sitio de splicing, pudiendo alterar este proceso con una consecuente alteración de la función de la proteína.

Absceso cerebral por Haemophilus influenzae serotipo e en un paciente pediátrico con Síndrome de Apert / Brain abscess caused by Haemophilus influenzae type e in a pediatric patient suffering from Apert syndrome

Se presenta el caso de un absceso cerebral causado por Haemophilus infl uenzae tipo e, en un paciente de 12 años con síndrome de Apert. El síndrome de Apert se caracteriza por el cierre prematuro de las suturas craneales. En 2010, el paciente presentó traumatismo craneano en región frontal, fractura y fístula de líquido cefalorraquídeo. En febrero de 2013 consultó por fi ebre, vómitos y convulsión tónica clónica generalizada, con deterioro progresivo del sensorio. La tomografía axial computarizada mostró una lesión frontal derecha, edema perilesional, leve dilatación ventricular y pansinusitis. Se diagnosticó absceso cerebral con pioventriculitis y se realizó drenaje. Se obtuvo desarrollo de un cocobacilo gram negativo, que fue identifi cado como H. infl uenzae serotipo e. Se realizó tratamiento empírico con meropenem (120 mg/kg/día) y vancomicina (60 mg/kg/día). Luego del resultado del cultivo, se rotó a ceftriaxona (100 mg/kg/día) y metronidazol (500 mg/8 h). El paciente cumplió 8 semanas de tratamiento y se observó evolución favorable

We report a case of a brain abscess caused by Haemophilus infl uenzae type e in a 12 year-old patient suffering from Apert syndrome. Apert syndrome is characterized by the premature closure of cranial sutures. In 2010 the patient suffered head trauma in the frontal area with cranial fracture and a cerebrospinal fl uid fi stula. In February 2013 he was admitted to hospital with fever, vomiting and generalized tonic-clonic seizure with deteriorating mental status/progressive sensory impairment. The computerized axial tomographic scan showed a right frontal lesion, perilesional edema, mild ventricular dilatation and pansinusitis. A brain abscess was diagnosed and drained. The clinical sample was then cultured. A gram negative coccobacillus was isolated and identifi ed as Haemophilus infl uenzae serotype e. Empirical treatment was started with meropenem (120 mg/kg/day) and vancomycin (60 mg/kg/day), which was later switched to ceftriaxone (100 mg/kg/day) and metronidazole (500 mg/8 h) after culture results arrived. The patient was discharged in good clinical condition

Este relato de caso mostra o diagnóstico de uma patologia congênita rara: Síndrome de Apert. Paciente do sexo feminino, 12 anos, melanoderma, apresentou aos exames clínico e radiográfico: acrobraquicefalia, sindactilia em mãos e pés, acne facial, nariz disforme, retrusão maxilar, pseudoprognatismo, hipertelorismo, proptose ocular, depressão das fissuras palpebrais laterais, lábios em forma trapezoidal, lábio superior protruso, pseudomacroglossia, mordida aberta anterior, mordida cruzadaposterior, palato em arco bizantino, múltiplas anomalias dentárias de posição (apinhamento dental maxilar e giroversões) e forma (ponte de esmalte pronunciada em incisivos laterais e taurodontismo em segundos molares), e alongamento do processo estilóide bilateral. A qualidade de saúde bucal da paciente era insatisfatória, com excesso de biofilme oral, cárie, doença periodontal e comprometimento endodôntico. O teste AUQEI apontou que a criança possuía baixa a moderada qualidade de vida. Este caso destaca a importância do diagnóstico precoce para intervenções clínico-cirúrgicas mais eficazes e o valor da equipe multidisciplinar no acompanhamento contínuo e na melhora da qualidade de vida de pacientes infantis portadores de anomalias congênitas severas.

This case report shows the diagnosis of a rare congenital pathology: Apert syndrome. A 12-year-old female patient, melanoderm, presented in clinical and radiographic examinations: acrobraquicephalia, syndactilia in hands and feet, facial acne, unshapely nose, maxillary retrusion, pseudoprognatism, hypertelorism, ocular proptosis, depression of the lateral palpebral fissures, trapezoid shaped appearance to the lips, upper lip protrusion, pseudomacroglossia, anterior open bite, posterior crossbite,Byzantine-arch palate, multiple dental anomalies of position (maxillary dental crowding and dental rotation) and shape (pronounced enamel bridge in lateral incisors and taurodontism in second molar teeth) and bilateral elongated styloid process. The quality of oral health was unsatisfactory in the patient, with excessive oral biofilm, carie lesion, periodontal disease and endodontic involvement. The AUQEI test showed that the child had a low to moderate quality of life. This case highlight the importance of an early diagnosis for more effective clinical and surgical interventions and the value of a multidisciplinary team in the continuousmonitoring and improvement of quality of life in pediatric patients with severe congenital abnormalities.

Apert syndrome with omphalocele: a case report.

Apert syndrome is a genetic disorder known as acrocephalopolysyndactyly type 1 caused by mutations in the fibroblast growth factor receptor 2 and characterized by coronal craniosynostosis, symmetric bone and skin syndactyly of hands and feet, and craniofacial dysmorphic features. The estimated prevalence of this syndrome is 10 to 15.5 cases per 1,000,000 live births. Apert syndrome has considerable clinical variability. We present a case of Apert syndrome and associated features reported to the National Registry of Congenital Anomalies of Argentina (RENAC). The reported case had omphalocele, esophageal atresia, and mega cisterna magna. The last two signs were reported several times as part of the clinical presentation of Apert syndrome. To our knowledge, this is the second reported case diagnosed with Apert syndrome associated with omphalocele.
