ABSTRACT

Objetivo: Describir las características bucales prevalentes de pacientes argentinos con mucopolisacaridosis (MPS) atendidos en el Servicio de Odontología del Hospital Nacional "Prof. Alejandro Posadas". Materiales y métodos: Se consideraron las historias clínicas de 19 pacientes con diagnóstico de MPS. Se registraron la edad, el sexo, el lugar de residencia, el tipo de MPS y la presencia de retraso madurativo. La muestra estuvo constituida por 13 niños (6,7±3 años) y 6 adultos (26±9 años): 2 eran mujeres (1 con MPS tipo I; 1 con MPS tipo IV A) y 17 eran hombres (15 con MPS tipo 2; 1 con MPS tipo 1; 1 con MPS tipo III); 13 de los pacientes presentaban discapacidad intelectual. Se evaluaron: tipo de dentición, oclusión, macroglosia, hipoplasias del esmalte, tipo de respiración predominante, clase molar y tratamiento realizado. Resultados: Ambos casos con MPS I presentaban mordida abierta anterior y giroversión dental, y solo uno de estos, diastemas, microdoncia, hipoplasias del esmalte, macroglosia y respiración bucal. De los 15 pacientes con MPS II, 11 presentaban mordida abierta anterior (73%), 3 mordida cruzada posterior (20%), 5 giroversión dental (33%), 11 diastemas (73%), 3 retraso en la erupción (20%), 4 hiperplasia gingival (26%), 13 macroglosia (87%), 7 hipoplasias del esmalte (47%), 2 microdoncia (13%), 9 respiración bucal (60%). Se registraron 5 pacientes con clase molar I (33%), 3 con clase molar II (20%), 3 con clase molar III (20%) y en 3 casos no se pudo evaluar (20%). En el paciente con MPS tipo III se halló mordida abierta anterior, diastemas, retraso en la erupción, macroglosia, respiración bucal y clase molar II; y en el caso de MPS tipo IV A, mordida abierta anterior, diastemas, hiperplasia gingival, macroglosia y clase molar II. El 90% de los pacientes requirió tratamiento odontológico (AU)


Aim: To identify the most prevalent oral manifestations of 19 Argentine patients with mucopolysaccharidos (MPS) attending the Dentistry Service of the National Posadas Hospital. Materials and methods: The medical records of 19 patients diagnosed with MPS were considered. Age, sex, place of residence, type of MPS, and presence of maturational delay were recorded. The sample consisted of 13 children (6.7 ± 3 years) and 6 adults (26 ± 9 years): 2 were women (1 with MPS type I; 1 with MPS type IV A) and 17 were men (15 with MPS type 2; 1 with MPS type 1; 1 with MPS type III); 13 of the patients had intellectual disabilities. The following were evaluated: type of dentition, occlusion, macroglossia, enamel hypoplasia, predominant type of respiration, molar class and treatment performed Results: Both cases with MPS I presented anterior open bite and dental gyroversion, and only one of these, diastemas, microdontia, enamel hypoplasia, macroglossia and mouth respiration. Of the 15 patients with MPS II, 11 presented anterior open bite (73%), 3 posterior crossbite (20%), 5 dental gyroversion (33%), 11 diastemas (73%), 3 delayed eruption (20%), 4 gingival hyperplasia (26%), 13 macroglossia (87%), 7 enamel hypoplasia (47%), 2 microdontia (13%), 9 mouth breathing (60%). 5 patients with molar class I (33%), 3 with molar class II (20%), 3 with molar class III (20%) and in 3 cases it could not be evaluated (20%). In the patient with type III MPS, anterior open bite, diastemas, delayed eruption, macroglossia, mouth breathing and molar class II were found; and in the case of type IV A MPS, anterior open bite, diastemas, gingival hyperplasia, macroglossia and molar class II. 90% of the patients required dental treatment. Conclusion: The most observed oral manifestations were macroglossia (84.2%) and anterior open bite (73%) (AU)

ABSTRACT

La mucopolisacaridosis tipo I es una enfermedad de depósito lisosomal, autosómica recesiva, de baja incidencia, aproximadamente 1:100.000 recién nacidos. Su etiología es el déficit de la glicosidasa, -L-iduronidasa (IDUA), que es una enzima que degrada los glicosaminoglicanos (GAG), heparán sulfato y dermatán sulfato. El déficit causa su acumulación progresiva a nivel intralisosomal, y posteriormente desencadena el daño a nivel celular y tisular. La gran heterogeneidad fenotípica depende del tipo de mutación del gen IDUA, ubicado en el cromosoma 4p16.3. Los casos más severos se denominan síndrome de Hurler, los intermedios, síndrome de Hurler-Scheie y el fenotipo más atenuado corresponde al síndrome de Scheie.1 Los pacientes con síndrome de Hurler habitualmente fallecen en la primera década de vida. En el síndrome de Scheie la sobrevida es normal y su sintomatología es más atenuada. El síndrome de Hurler-Scheie tiene un curso intermedio, falleciendo cerca de los 20 años por compromiso cardiorrespiratorio. La fascies tosca, talla baja, retraso del desarrollo psicomotor progresivo, opacidad corneal y hepatomegalia deben plantear la sospecha clínica de la forma más severa de esta enfermedad, que es letal sin tratamiento. El objetivo de esta comunicación es presentar un caso de síndrome de Hurler con manifestaciones cutáneas como motivo de consulta.


Mucopolysaccharidosis type I is an autosomal recessive genetic disorder that has a low incidence of approximately 1:100.000 new born. It is caused by the deficiency of -L- iduronidase (IDUA), a lysosomal enzyme involved in the degradation of the glycosaminoglycans, heparan sulfate and dermatan sulfate. This deficient activity leads to intracellular accumulation and ultimately compromises cellular and organ function. The -L- iduronidase gene (IDUA) is located on chromosome 4p16.3. The phenotypic heterogeneity ranging from the most severe (Hurler syndrome) to the most attenuated phenotype (Scheie syndrome) is related to the different mutations.1 Life expectancy for Hurler disease is less than ten years; Scheie syndrome has a normal survival rate and its symptomatology is less severe; Hurler-Scheie syndrome follows an intermediate line and life expectancy is approximately twenty years due to cardiorespiratory complications. The most appropriate approach to patients with coarse facial features, short stature, hepatosplenomegaly, corneal clouding and progressive mental retardation is to perform a diagnostic test to rule out the presence of a mucopolysaccharidosis. Early diagnosis and adequate treatment prevent its progression, which can otherwise be lethal. We present a case of Hurler syndrome with cutaneous symptoms whose reason for consultation was dermatological.

ABSTRACT

A 7-year-old girl had large and diffusely cloudy corneas. Course facial [gargoyle-like] features, hypertelorism, large protuberant tongue, dwarfism with skeletal abnormalities, short and stubby hands, thick skin with hypertrichosis, respiratory and cardiac disease, mental retardation, and excessive urinary acid mucopolysaccharides [dermatan sulfate and heparan sulphate] and histopathologic features of tissue biopsy confirmed the diagnosis of classic Hurler's disease
