Fissura de palato isolada não sindrômica: estudo do fenótipo, recorrência familial e histórico gestacional / Nonsyndromic isolated cleft palate: a study of its phenotype, familial recurrence and gestational history

Garbieri, Thais Francini 01 March 2016 (has links)
A fissura labiopalatina (FL/P) é uma das malformações craniofaciais mais comuns em humanos, com variação epidemiológica nas diferentes populações. Possui diferentes apresentações clínicas, divergindo de acordo com a extensão e estruturas acometidas, podendo acometer somente o lábio ou lábio e palato em conjunto, uni ou bilateralmente, de maneira completa ou incompleta ou apenas o palato (FP) tanto completa como incompletamente. Podem fazer parte de um quadro sindrômico, recebendo a denominação de FL/P sindrômica ou acontecer como um fenótipo isolado, sendo chamada de FL/P isolada ou não sindrômica. Em relação a etiologia da FL/P não sindrômica, a literatura afirma ser multifatorial com a predisposição genética associada a fatores ambientais. Apesar de se apresentarem frequentemente associadas, a FL/P e FP não sindrômicas são consideradas etiologicamente e embriologicamente distintas. Objetivo: Aprofundar e ampliar o conhecimento das FP isoladas não sindrômicas, descrevendo o fenótipo principal (FP isolada) e seus subfenótipos clínicos, investigando o fator genético relacionado à recorrência por meio do histórico familial e buscando elucidar possível fatores ambientais envolvidos por meio do histórico gestacional. Material e métodos: Foram coletados dados de 165 prontuários médicos de pacientes com FP isolada não sindrômica matriculados no Hospital de Reabilitação de Anomalias Craniofaciais da Universidade de São Paulo (HRAC-USP). Para a coleta desses dados foram analisados segmentos do prontuário referentes a atendimentos realizados no HRACUSP em diferentes setores. Resultados: Em 165 pacientes estudados, o sexo feminino foi o mais acometido com 106 casos (64,24%) encontrados. O tipo de FP predominante foi a incompleta correspondendo a 88,48% da amostra total, sendo dentre elas a fissura de palato duro parcial a mais prevalente. Em cinco casos não foi possível realizar a classificação nos grupos referentes ao tipo de fissura adotados, sendo necessária a criação de um grupo de classificação adicional. Recorrência familial positiva foi relatada em 28,47% de 144 casos em que havia informação, e na maioria das vezes havia apenas 1 outro familiar acometido. A média da idade das mães e dos pais no momento da concepção foi de 26,9 e 31,4 anos, respectivamente. A porcentagem de abortos anteriores foi de 11,95% dos 92 casos informados e a consanguinidade foi de 3,29% dos 91 casos informados. A intercorrência mais frequentemente relatada (25 em 154 casos informados) foi o uso de medicamentos, tais como, antibióticos, anti-hipertensivos e medicamentos que auxiliam na prevenção do parto prematuro. Conclusão: O fenótipo FP isolada possui variações quanto à extensão de cometimento, sendo que as fissuras incompletas foram as mais frequentes e o sexo feminino predominantemente acometido. Em relação ao histórico familial e gestacional os dados que mais chamaram atenção estão relacionados ao percentual de recorrência familial (28,47%) e o uso de medicação durante a gestação. / Cleft lip and palate (CL/P) is one of the most common craniofacial malformations in humans, with epidemiological variation in different populations. It has different clinical presentations that diverge according to the extension and affected structures, and may either affect the lip or lip and palate together, unilaterally or bilaterally, in a complete or incomplete way or just affect the palate (CP) completely or incompletely. CL/P can either be related to a syndrome, classified as syndromic CL/P or unrelated to a syndrome, occurring as an isolated phenotype, designated as isolated or nonsyndromic CL/P. Regarding the etiology of nonsyndromic CL/P, research indicates multifactorial causes with a genetic predisposition associated with environmental factors. Although it is often present in association, nonsyndromic CL/P and CP are considered embryologically and etiologically distinct. Objective: To deepen and broaden the knowledge of individual nonsyndromic CP, describing the main phenotype (isolated CP) and its clinical subphenotypes, investigating the genetic factors related to recurrence through family history and to elucidate possible environmental factors involving gestational history. Material and Methods: Data were collected from 165 medical patients records with isolated nonsyndromic CP enrolled at the Hospital de Reabilitação de Anomalias Craniofaciais da Universidade de São Paulo (HRAC-USP). For data collection, segments of the records pertaining to care provided by HRAC-USP in different sectors were analyzed. Results: In the 165 patients studied, females were the most affected with 106 cases (64.24%) found. The predominant type of CP was incomplete corresponding to 88.48% of the total sample, and among these incomplete CP, the clefts involving partial hard palate were the most prevalent. In five cases it was impossible to classify the type of cleft, and the creation of an additional classification group was required. Positive familial recurrence was reported in 28.47% of 144 cases where information was available and in most cases there was only one other affected family member. The average age of mothers and fathers at conception was 26.9 and 31.4 years respectively. The percentage of previous miscarriages was 11.95% of the 92 reported cases and consanguineous marriage was found in 3.29% of the 91 reported cases. The most frequently reported complication (25 in 154 reported cases) was the use of drugs such as antibiotics, antihypertensives drugs, and drugs used to prevent premature birth. Conclusion: The phenotype Isolated CP presents variations in the extent of involvement, and incomplete clefts were the most frequent, with females predominantly affected. Regarding family history and gestational data what calls more attention were the percentage of familial recurrence (28.47%) and the use of medication during pregnancy.

Dreidimensionale Modellanalyse der Oberkiefermorphologie bis zum operativen Gaumenspaltverschluss von Patienten mit isolierter Gaumenspalte im Vergleich zur Pierre-Robin-Sequenz

Wolf, Susanne 05 March 2014 (has links) (PDF)
Die vorliegende Arbeit befasst sich mit der dreidimensionalen Untersuchung und Beschreibung der Oberkiefermorphologie von isolierten Gaumenspalten im ersten Lebensjahr. Hierzu wurden Oberkieferabformungen von nicht-syndromalen isolierten Gaumenspalten und Säuglingen mit Pierre-Robin-Sequenz bis zum operativen Gaumenspaltverschluss miteinander verglichen. Zusätzlich erfolgte die Gegenüberstellung einer gesunden Kontrollgruppe. Bei den Robin-Patienten waren eine signifikant vergrößerte anteriore Zahnbogenlänge, sowie eine verstärkte posteriore Zahnbogenbreite nachweisbar. Im Vergleich zu dieser tendenziell parabelförmigen Zahnbogenform, wiesen die isolierten Gaumenspalten einen eher u-förmigen Zahnbogen auf. Setzt man die Ergebnisse aus den Untersuchungsgruppen ins Verhältnis zur Zahnbogenform eines gesunden Säuglings, ergeben sich teilweise ganz andere Tendenzen. Die untersuchten Säuglinge weisen gegenüber der gesunden Population im gesamten ersten Lebensjahr eine signifikant verbreiterte posteriore Zahnbogenbreite auf. Zudem zeigen beide Gruppen im Vergleich zu der gesunden Kontrollgruppe ein deutliches Längendefizit im anterioren Bereich. Dieses Defizit führt zum Ende des ersten Lebensjahres zu einem zunehmenden Wachstumsrückstand der Gesamtzahnbogenlänge.
