Abordagem interdisciplinar no tratamento da macroglossia na síndrome de Beckwith-Wiedemann: relato de caso / Interdisciplinary approach in the treatment of macroglossia in Beckwith-Wiedemann syndrome: case report

RESUMO O objetivo deste estudo foi relatar a abordagem interdisciplinar no manejo da macroglossia em um caso de paciente com síndrome de Beckwith-Wiedemann, no período de dez anos. O acompanhamento iniciou pela equipe de Cirurgia Bucomaxilofacial, seguido da Fonoaudiologia, em função de dificuldades alimentares. Após avaliação clínica e instrumental, aos 8 meses de idade, iniciou-se a intervenção fonoaudiológica com foco na disfagia orofaríngea e na terapia miofuncional orofacial. Foi verificado, com 1 ano e 11 meses, ausência de sinais de alteração de deglutição em fase faríngea e melhora na postura de lábios e língua. Aos 3 anos, foram iniciados estímulos para retirada dos hábitos orais e o treino da função mastigatória. O tratamento ortodôntico para correção de mordida aberta anterior e mordida cruzada posterior unilateral iniciou-se aos 6 anos. Aos 7 anos e 5 meses de idade, constatou-se estabilidade do modo respiratório nasal e adequação da postura de repouso de lábios e língua. Aos 9 anos, em função de recidiva das alterações oclusais, optou-se pela redução cirúrgica da língua seguida de terapia miofuncional orofacial, retomada aos 9 anos e 3 meses. O resultado foi a correção da postura da língua na deglutição e a adequação da fala. A associação dos tratamentos, envolvendo Fonoaudiologia, Ortodontia e Cirurgia Bucomaxilofacial foi considerada efetiva no manejo da macroglossia, resultando na adequação e equilíbrio das funções orofaciais.

ABSTRACT This study aims to report the interdisciplinary management of macroglossia in a Beckwith-Wiedemann syndrome patient during ten years. Clinical follow-up started by the Oral and Maxillofacial Surgery team, followed by Speech Therapy due to feeding difficulties. After clinical and instrumental evaluation, at 8 months old, the speech therapy intervention was indicated, focusing on oropharyngeal dysphagia and orofacial myofunctional therapy. At 1 year and 11 months, no signs of swallowing alteration in the pharyngeal phase and improvement in the posture of the lips and tongue were found. At the age of 3, stimulation to remove oral habits and train masticatory function were initiated. Orthodontic treatment to correct anterior open bite and unilateral posterior crossbite started at age 6. At 7 years and 5 months, there was stability in the nasal breathing mode and adequacy of resting posture of lips and tongue. At the age of 9, due to relapse of the occlusal alterations, surgical reduction of the tongue was indicated, followed by orofacial myofunctional therapy, restarted at the age of 9 years and 3 months. The result was the correction of the posture of the tongue during swallowing and speech adequacy. The association of treatments involving Speech Therapy, Orthodontics and Oral and Maxillofacial Surgery was considered effective in the management of the macroglossia. It resulted in the adequacy and equilibrium of orofacial functions.

Clinical aspects, food management, and clinical evolution of a cat with hypertrophic muscular dystrophy / Aspectos clínicos, manejo alimentar e evolução clínica de um gato com distrofia muscular hipertrófica

Hypertrophic feline muscular dystrophy (HFMD), rarely reported in the literature, is a disease caused by a hereditary recessive dystrophin deficiency linked to the X chromosome, mainly affecting young male cats. Here, we presented the clinical aspects, food management, and clinical evolution of a seven-year-old mixed-breed cat diagnosed with HFMD, having a primary history of progressive tongue protrusion.

A distrofia muscular hipertrófica felina é uma doença causada por uma deficiência da distrofina com caráter hereditário recessivo ligado ao cromossomo X, com poucos registros de ocorrência na literatura, que acomete principalmente gatos machos jovens. Neste trabalho, são relatados os aspectos clínicos, manejo alimentar e evolução clínica de um gato, sem raça definida, de sete anos com histórico principal de protrusão progressiva da língua e diagnosticado com distrofia muscular hipertrófica felina.

Conclusion: The most observed oral manifestations were macroglossia (84.2%) and anterior open bite (73%) (AU)

Amiloidosis AL y mieloma múltiple: macroglosia como primera manifestación de una combinación infrecuente / AL amyloidosis and multiple myeloma: macroglossia as first manifestation of a rare combination

El diagnóstico diferencial de la macroglosia es amplio y puede estar en el contexto de una patología localizada o una enfermedad sistémica. Dentro de las enfermedades sistémicas que se manifiestan con macroglosia se describe la amiloidosis, caracterizada por un depósito irreversible de una proteína amorfa y fibrilar El compromiso de esta patología en el territorio de cabeza y cuello es infrecuente y su depósito en la lengua corresponde a menos del 9% de los casos. Se presenta el caso de un paciente que consultó por dolor en hemilengua derecha, disfagia y baja de peso. Se estudió inicialmente con exámenes de laboratorio y nasofibroscopía, sin hallazgos concluyentes. Dado persistencia de síntomas se realizó resonancia nuclear magnética (RM) que mostraba signos sugerentes de enfermedad de depósito, confirmándose mediante estudios histopatológicos una amiloidosis sistémica secundaria. El paciente fue derivado a hematología para completar estudio e iniciar el tratamiento. La amiloidosis sistémica es un diagnóstico infrecuente, que debe ser considerado por su mal pronóstico vital. El diagnóstico en etapas iniciales puede mejorar sustancialmente la sobrevida y calidad de vida de aquellos que padecen la enfermedad. Por lo anterior, es necesario completar un estudio acabado de la patología, apoyándose en métodos no invasivos como la RM.

The differential diagnosis of macroglossia is broad, and it may be present in the context of a localized pathology or a systemic disease. One of the systemic diseases that present macroglossia is amyloidosis, which is characterized by an irreversible deposit of an amorphous and fibrillar protein. The manifestation of this pathology in head and neck territory is infrequent, and its deposit in the tongue represents less than 9% of all types of amyloidosis. We present the case of a patient, who consulted with pain in the tongue, dysphagia, and weight loss. He was initially studied with laboratory tests and a nasofibroscopy with no conclusive findings. Given the persistence of symptoms, magnetic resonance imaging (MRI) was performed, showing signs of an infiltrative disease, which was confirmed as secondary systemic amyloidosis through histopathological studies. Given the above, the patient was referred to hematology to start treatment. Systemic amyloidosis is an uncommon diagnosis that should be suspected since it implies a poor vital prognosis. Moreover, an early diagnosis can substantially improve the survival rate and quality of life of those who suffer this disease. Therefore, a comprehensive study of this condition is needed, complementing with non-invasive methods such as MRI.

Prevalencia de lesiones bucales en tejido blando encontradas en la Clínica de Estomatología de la Facultad de Odontología de la Universidad de los Andes: periodo 2015-2018 / Prevalence of oral lesions in soft tissue found in the Clinic of Stomatology of the Faculty of Dentistry of the University of los Andes: 2015-2018 period

Introducción: La epidemiología sobre alteraciones en tejidos blandos bucales es limitada cuando se compara con caries, enfermedades periodontales y maloclusiones, por lo que su estudio representa un paso adelante en la odontología más allá de los dientes. Objetivo: Describir la prevalencia de las lesiones bucales en tejido blando encontradas en la Clínica de Estomatología de la Facultad de Odontología de la ULA, del 2015 al 2018, con la finalidad de proporcionar una fuente de datos actualizada, que oriente a una mejor prevención y oportuno diagnóstico. Material y métodos: Se realizó una investigación descriptiva, documental, retrospectiva y multivariable. Resultados: De 1,000 fichas clínicas estudiadas, las patologías más frecuentes fueron: lengua saburral (50.6%), queilitis (33.4%), traumatismo de la mucosa de los carrillos (27.6%), várices linguales (18.3%), anquiloglosia (13.7%) y agrandamiento de rugas palatinas (11.7%). La zona con mayor alteración fue la lengua (92.1%), mientras que el paladar fue la menos afectada (29%). De los hábitos predisponentes a la formación de lesiones, el mordisqueo de mucosa fue el más común (16.5%). En cuanto a los factores locales asociados, una higiene oral regular/ deficiente resultó el principal (53.8%). Conclusión: La educación del paciente sigue siendo considerada la clave para disminuir la aparición de patologías y su evolución a entidades más graves (AU)

Introduction: Epidemiological studies on soft tissue alterations in the mouth are limited when compared with caries, periodontal diseases and malocclusions, so their study represents a step forward in dentistry beyond the teeth. Objective: To describe the prevalence of soft tissue oral lesions found in the Stomatology Clinic of the ULA School of Dentistry, from 2015 to 2018, in order to provide an up-to-date data source, to guide better prevention and timely diagnosis. Material and methods: A descriptive and documentary, retrospective and multivariable research was carried out. The statistical package IBM SPSS Statistics v 23 was applied for the analysis. Results: 1,000 clinical records studied, the most frequent pathologies were: saburral tongue (50.6%), cheilitis (33.4%), traumatism of the cheek mucosa (27.6%), lingual varices (18.3%), ankyloglossia (13.7%) and enlargement of palatal rugas (11.7%). The tongue was the most affected (92.1%), while the palate was the least affected (29%). Of the predisposing habits to the formation of lesions, mucosal nipping was the most common (16.5%). Regarding the associated local factors, a regular / deficient oral hygiene was the main one (53.8%). Conclusion: Patient education is still considered the key to diminish not only the appearance of pathologies but their evolution to more serious entities (AU)

El síndrome de Beckwith-Wiedemann es una enfermedad congénita, poco frecuente, caracterizada por presentar macroglosia, defectos de la pared abdominal, hemihipertrofia, onfalocele, hipoglucemia neonatal, hernia umbilical, hepatomegalia, anomalías cardíacas, entre otros. La macroglosia se presenta en el 90% de los casos y genera problemas en la masticación, deglución, fonación y respiración, que ocasionan un cierre de la vía aérea superior. La opción terapéutica de elección es la glosectomía parcial. Se presenta a un paciente pediátrico de dos meses de nacido, con síndrome de Beckwith-Wiedemann y obstrucción de la vía aérea por macroglosia grave. En los antecedentes médicos, se reportaron cardiopatías congénitas, comunicación interauricular, conducto arterioso persistente, epilepsia sintomática, falla renal, hipoglicemia, traqueotomía y gastrostomía por el colapso de la vía aérea y disfagia. Se realizó la técnica quirúrgica de glosectomía de reducción anterior, con resultados favorables.

Beckwith-Wiedemann syndrome is a rare congenital condition, characterized by presenting macroglossia, defects of the abdominal wall, hemihypertrophy, omphalocele, neonatal hypoglycemia, umbilical hernia, hepatomegaly, cardiac abnormalities, among others. Macroglossia occurs in 90% of cases, causing a problem in chewing, swallowing, phonation and breathing, resulting in a closure of the upper airway. The therapeutic option of choice is partial glossectomy. We present a 2-month-old pediatric patient with Beckwith-Wiedemann syndrome and area blockage due to severe macroglossia; in the medical history, congenital heart disease, interatrial communication, persistent ductus arteriosus, symptomatic epilepsy, renal failure, hypoglycemia, tracheotomy and gastrostomy, due to airway collapse and dysphagia. It was performed an anterior tongue reduction surgery as a surgical treatment with favorable results.

Oral manifestations in children with mucopolysaccharidosis / Manifestações orais de mucopolissacaridose em crianças

BACKGROUND: Patients with mucopolysaccharidosis have several changes of the stomatognathic complex, representing a challenge for dentists. OBJECTIVE: The study aimed to evaluate and characterize oral health in patients with mucopolysaccharidosis in a reference center of Portugal. METHOD: The sample consisted of twelve participants with mucopolysaccharidosis followed in Metabolic Diseases Unit of the S. João Hospital Centre and twelve healthy participants followed at Faculty of Dental Medicine, University of Porto. The clinical oral evaluation was performed by a complete extra-oral and intra-oral examination to assess the presence of oral pathologies, gingival index and occlusion status. RESULTS: Mucoplysaccaridosis patients and controls presented similar age ranges and sex distribution. In comparison to controls, children with mucopolysaccharidosis presented a higher prevalence of tooth decay, gingival bleeding, macroglossia, dental hypoplasia, lingual interposition, delayed tooth eruption, anterior open bite, right and left posterior cross-bite, limitation of mouth opening, alteration on the size and shape of the teeth, diastemata and maxillary compression. CONCLUSIONS: Patients with mucopolysaccharidosis have a high prevalence eruption delay, teeth morphology alterations, occlusal problems, dental caries and bleeding gums, highlighting the need of oral health care providers to improve diagnostics and preventive protocols to overcome the factors that limit the oral health of these patients and promote together with parent/caregiver efficient oral care strategies.

INFORMAÇÕES GERAIS: Os pacientes com mucopolissacaridose apresentam diversas alterações do complexo estomatognático, representando um desafio para os médicos dentistas. OBJETIVO: O estudo pretendeu avaliar e caracterizar a saúde oral em pacientes com mucopolissacaridose num centro de referência em Portugal.

Glossectomia parcial associada à cirurgia ortognática: relato de caso / Partial glossectomy associated with orthognathic surgery: case report

A macroglossia é caracterizada pelo aumento de volume da língua, a qual afeta todo o sistema estomatognático em função de sua posição e tamanho. Ela é considerada um fator etiológico para: mordida aberta, protrusão bimaxilar, espaçamento entre os arcos dentários e pode causar instabilidade pós-tratamento ortodôntico/ortodôntico-cirúrgico. Aglossectomia é uma cirurgia com prognóstico favorável, pois melhora a estabilidade oclusal, esta pode ser associada antes, simultaneamente ou após a cirurgia ortognática. Nos casos em que o tamanho da língua inviabiliza a realização da cirúrgiaortognática. Descrever um relato de caso de glossectomia associada à cirurgia ortognática, apresentando o diagnóstico, tratamento instituído, técnica cirúrgica e acompanhamento pós operatório. Paciente sexo feminino, acompanhada há 10 anos pelo preceptor do serviço foi submetida à cirurgia ortognática e glossectomia em mesmo tempo cirúrgico, com retração mandibular instituída através de osteotomia bilateral e fixação com duas placas no sistema 2.0. A técnica selecionada para a glossectomia foi de "buraco de fechadura" modificada sem avançar a incisão muito a posterior. Não houve sequelas e a paciente ficou muito satisfeita com o resultado. A macroglossia é uma condição de difícil diagnóstico que precisa ser tratada para uma melhor qualidade de vida e desenvolvimento do paciente, melhor resultado pós operatório em cirurgias ortognáticas, evitar recidivas devido a memória muscular e a influência da língua na posição alvéolo dentaria(AU)

The macroglossia is characterized by an increase in the volume of the tongue, which affect the entire stomatognathic system in function of the tongue position and size. It is considered an etiological factor for: open bite, bimaxillary protrusion, spacing between dental arches and may cause orthodontic / orthodontic-surgical post-treatment instability. Glossectomy is a surgery with favorable prognosis, because cause a improvement of occlusal stability, may be associated before, simultaneously or after an orthognathic surgery. In cases where the size of the tongue makes it impossible to perform orthognathic surgery. To describe a case report of glossectomy associated with orthognathic surgery, presenting the diagnosis, treatment instituted, surgical technique and postoperative follow-up. Female patient, followed for 10 years by the preceptor of the service. She had been submited toaorthognathic surgery and glossectomy in one surgical time, with mandibular retraction instituted through bilateral osteotomy and fixation with two plaques in the 2.0 system. The technique selected for glossectomy was a modified "keyhole" without advancing the incision much later. There were no sequels and patient was very satisfied with the result. Macroglossia is a difficult diagnosis condition that needs to be treated for a better quality of life and development of the patient, better postoperative result in orthognathic surgeries, to avoid relapses due to a Muscular memory and the influence of the tongue in the dental alveolus position(AU)

Glossectomia subtotal pela técnica de ressecção lingual em orifício de fechadura modificada como tratamento de macroglossia verdadeira / Subtotal glossectomy by modified keyhole lingual resection technique for the treatment of true macroglossia

Neste artigo é apresentado o caso de macroglossia verdadeira em criança de 6 anos de idade, tratada cirurgicamente, com excisão elíptica na linha média da língua e ressecção ampla na ponta da língua em arco gótico. O resultado pós-operatório foi considerado satisfatório, tanto sob o aspecto de volume da língua, que passou a se manter totalmente dentro da boca, como sob o aspecto estético, mantendo a capacidade de gustação normal.

We describe a case of true macroglossia in a 6-year-old child that was surgically treated with a midline elliptical excision and anterior wedge resection along a Gothic-shaped arch. The postoperative result was considered satisfactory with regard to both the volume of the tongue, which now remains entirely within the mouth, and the aesthetic appearance; the ability to taste has been maintained.

Glosoplastía con técnica de Harada en un paciente con síndrome de Down / Glossoplasty with Harada´s technique in a patient with Down syndrome

La macroglosia es una patología que afecta frecuentemente a los niños que padecen síndrome de Down, lo cual condiciona que la lengua siempre se encuentre expuesta al medio externo y sufra marcada sequedad. Por estas razones se ha señalado que al tratar quirúrgicamente la macroglosia existente no solo mejoraría del aspecto estético y la aceptación social, sino que funcionalmente mejora el lenguaje, el desarrollo mandibular, la mordida abierta, y ocurre espontáneamente la recolocación del arco dental. Así se han creado y modificado una serie de técnicas quirúrgicas para reducir el tamaño de la lengua. En el artículo se presenta un caso clínico de una paciente con síndrome de Down que fue sometida a una glosoplastía con la técnica de Harada. Se discute los beneficios de las glosoplastías, así como las diferentes técnicas empleadas para ello.

Macroglossia is a condition that often affects children with Down syndrome, it makes the tongue to always be exposed to the environment and suffer noticeable dryness. For these reasons it has been demonstrated that macroglossia treated surgically not only improves the esthetic aspect and the social acceptance, but functionally improves language, development of the mandible, and open bite, with repositioning of the dental arch occurring spontaneously. Many surgical techniques have been created and modified to reduce the size of the tongue. In this article we present the case of a patient with Down syndrome who underwent a glossoplasty with the Harada’s technique. The benefits of the glossoplasties, as well as the different techniques used for it are discussed.

Destacamos la importancia del examen físico en la consulta dermatológica como oportunidad diagnóstica.

Beckwith-Wiedemann’s syndrome is a sporadic or hereditary rare disor-der characterized by macroglosia, omphalocele, visceromegalia, hypo-glycemia and hemihypertrophy.We report the case of a 1 month-old infant with a history of nephromegalia detected by prenatal ultrasound scan, who presented various generalized hemangiomas.On examination she had macroglosia, hemihypertrophy, omphalocele and high body weight. She also had alpha feto protein 608 ng/ml withno further abnormalities, leading us to diagnose Beckwith-Wiedemann ́s syndrome.The interest of this case is to report an infrecuent syndrome in a patient with diagnosis of neonatal hemangiomatosis. This association has not been previously reported in the literature. We wish to emphasize the importance of a thorough physical exam as part of the dermatologic consultation leading to the correct diagnosis.

Histoplasmosis oral localizada: reporte de un caso clínico en Tucumán, Argentina / Localized oral histoplasmosis: report of one case

Histoplasmosis is an endemic deep mycosis produced by Histoplasma capsulatum, a dimorphic fungus. It penetrates into the organism by inhalation and spreads by lymphatic or hematic route. We report a 57-year-old immunocompetent male presenting with an enlargement of the tongue that also exhibited white pseudomembranes. There were also nodular lesions in the dorsum of the tongue, separated by deep grooves. The pathological study revealed a chronic infammatory process with granulomas. The microbiological examination with the Giemsa technique showed multiple yeasts of 4-5 mm of diameter with a clear halo inside macrophages and epithelial cells, compatible with the parasitic phase of Histoplasma capsulatum. Serology was positive for the histoplasmine antigen. The patient was treated with Itraconazole 200 mg/day, experiencing 40 percent remission of lesions during the frst month of treatment.
