Orthodontics and Moebius syndrome: an observational study.

BACKGROUND: Moebius syndrome is a rare condition characterized by bilateral facial and abducens nerve paralysis. The aim of this study is to evaluate the main orthodontic features and the frequency of associated clinical characteristics in patients with Moebius syndrome (MS). METHODS: According to Terzis classifications, 58 patients with MS aged 8 months to 46 years old underwent orthodontics and clinical examination. RESULTS: Strabismus, upper and lower limb malformations, lip and palatal cleft were frequently associated with MS. Reduced TM movements were noted (48%). Cephalometric analysis did not allow identifying a typical facies and a characteristic cephalometric pattern; we have noticed a higher prevalence of Class II (56%) with micrognathia and excessive maxillary development probably due to the lack of lip seal. Early treatment is recommended, with a multidisciplinary approach to reduce the impact of sequelae on the lives of MS patients or their families. CONCLUSIONS: Early treatment is recommended, with a multidisciplinary approach to diminish the impact of sequelae on the lives of MS patients or their families.

Asociación sindromática: Poland, Goldenhar, Moebius, Klippel-Feil: presentación de un caso clínico / Poland, Goldenhar, Moebius, Klippel-Feil syndrome: a clinical case

Poland Syndrome is a congenital defect characterized by a unilateral absence of the clavicular and stem costal portion of the pectoral muscles associated to abnormalities of other muscles of the thoracic wall, ribs, breast and upper extremity. It is found in one of 20 to 32 thousand newborns. It is found sometimes associated to other syndromes, most often with Moebius Syndrome, and rarely with Goldenhar and Klippel-Feil. Due to the association, a common pathogenic cause has been postulated, that being an anomaly of vascularization during embryonic development. Clinical Case: A newborn male was seen who presented with Poland, Goldenhar, Moebius and Klippel-Feil Syndromes. Clinically, he presented left hemi facial microsomy, microtia, shortening and paralysis of the facial nerve; his neck was short and movement was limited due to C4-C5 fusion; agenesis of left pectorals, hypoplasia of left radius and hand. There were no known additional family cases, being thus, a sporadic syndromatic association.

Introducción: El síndrome de Poland es un defecto muscular congénito, heterogéneo, caracterizado por ausencia unilateral de las porciones clavicular y/o esternocostal del músculo pectoral mayor, que se puede asociar a compromiso de otros músculos de la pared torácica, costillas, mama y extremidad superior. Se presenta con una frecuencia entre 1/20 000 al/32 000 nacidos. El síndrome de Poland se presenta en algunas ocasiones asociado a otros síndromes, siendo clásica con el síndrome de Moebius. Excepcionalmente se ha descrito la aparición conjunta con otros síndromes como Goldenhar y Klippel-Feil. Por la relación que existe entre ellos se plantea una patogenia común: anomalía en la vascularización, durante el desarrollo embrionario. Caso Clínico: Paciente de sexo masculino, con asociación sindromática de Poland, Goldenhar, Moebius y Klippel-Feil. Como características clínicas presenta a izquierda microsomia hemifacial, microtia, acortamiento de rama mandibular y parálisis facial; cuello corto y limitación de movimientos por fusión de C4-C5; agenesia del pectoral mayor izquierdo, hipoplasia de radio y mano izquierda. Sin antecedentes familiares, se trataría de un caso esporádico de asociación sindromática.

Prenatal exposure to misoprostol and congenital anomalies: systematic review and meta-analysis.

The present systematic review was proposed with the objective of estimating the risk of congenital anomalies and other adverse events in children exposed to misoprostol during fetal life. The data source consisted of case-control studies that analyzed the effect of prenatal exposure to misoprostol on the pregnancy outcome, which were located in electronic databases and published up to June 2005. The outcomes of interest included congenital anomalies, fetal death, low birth weight and prematurity. The odds ratios (OR) for the individual studies were pooled by meta-analysis. Sensitivity tests and heterogeneity analysis were performed. Four studies involving 4899 cases of congenital anomalies and 5742 controls were included in accordance with the selection criteria. None of the studies analyzed other adverse effects from misoprostol on the outcome from gestation. Increased risks of congenital anomalies related to misoprostol use were found for any congenital defect (OR=3.56; 95% CI: 0.98-12.98), Möbius sequence (OR=25.31; 95% CI: 11.11-57.66) and terminal transverse limb defects (OR=11.86; 95% CI: 4.86-28.90). In conclusion, prenatal exposure to misoprostol is associated with an increased risk of Möbius sequence and terminal transverse limb defects.
