Desempenho motor oral na fissura labiopalatina / Oral motor performance in cleft lip and palate

Modolo, Daniela Jovel 11 October 2012 (has links)
Objetivo: Estudar a habilidade motora do lábio e da língua em indivíduos com fissura isolada de palato e em indivíduos com fissura de palato associada à fissura labial, comparativamente a indivíduos sem fissura labiopalatina. Método: Participaram do estudo 88 crianças de ambos os sexos, com idade entre 9 e 12 anos, distribuídas em três grupos: 28 crianças com fissura pós-forame incisivo operada, 30 com fissura transforame incisivo unilateral operada e 30 sem fissura labiopalatina ou má oclusão que constituiu o grupo controle. Avaliou-se a mobilidade dos lábios e da língua, a partir de imagens gravadas de 12 movimentos dos lábios e 17 da língua; a atividade eletromiográfica do lábio superior obtida com eletrodos bipolares de superfície durante a protrusão dos lábios, considerada atividade máxima, e na produção da silaba pa, calculando-se a porcentagem da máxima atividade labial utilizada na emissão da sílaba; além do teste da DDC a partir da repetição das sílabas pa, ta, ca e da sequência pa-ta-ca, analisando-se para as sílabas os parâmetros fornecidos pelo programa Motor Speech Profile Advanced (MSP) da KayPENTAXTM, e para a sequência pataca a contagem do número de emissões por segundo. Resultados: Quanto à mobilidade, verificou-se menor escore para os lábios no grupo controle comparado aos dois grupos fissura e menor escore para a língua no grupo controle que no grupo com fissura transforame. Em relação à atividade eletromiográfica, não houve diferença entre os grupos para a protrusão labial, mas a porcentagem da máxima atividade utilizada na emissão da sílaba foi maior no grupo pós-forame comparado aos grupos controle e transforame. Para a DDC, obteve-se maior número de emissões por segundo e menor tempo médio entre as emissões da sílaba ca no grupo controle comparado ao grupo transforame e maior número de emissões por segundo da sequencia pataca no grupo controle que no grupo pós-forame. Conclusão: Na amostra estudada, a mobilidade labial foi reduzida nos grupos com fissura e a mobilidade lingual foi reduzida no grupo transforame comparado ao grupo sem fissura; maior porcentagem da atividade máxima labial para produzir a silaba pa foi utilizada na fissura pós-forame; a velocidade de emissão da sílaba ca foi menor na fissura transforame, assim como na fissura pós-forame houve menos emissões da sequência pa-ta-ca que no grupo sem fissura. / Objective: To investigate the tongue and lips motor ability in subjects with isolated cleft palate as well as in subjects with cleft palate associated with cleft lip compared to subjects without cleft lip and palate. Methods: Eighty eight children with both genders, between the ages of 9 and 12 years old, took part in this investigation. Being distributed in three groups: 28 children with repaired isolated cleft palate, 30 with repaired unilateral cleft lip and palate and the control group which consisted of 30 children without cleft lip and palate or malocclusion. This investigation assessed the lips and tongue mobility through recorded images of 12 lips movements and 17 tongue movements; the electromyographic activity of the upper lip, which was obtained through bipolar surface electrodes during the protrusion of the lips, considered as the maximal activity, and during the production of the syllable \"pa\", by calculating the percentage of the lips maximal activity used in the syllable emission and the DDK test through the repetition of the syllables pa, ta, ca and the sequence pa-ta-ca, by analyzing the syllables through the parameters provided by the program Motor Speech Profile Advanced (MSP) of the KayPENTAXTM, and the sequence pataca by counting the number of emissions per second. Results: Regarding the mobility, it was verified a lower score to the lips in the control group than in the other two groups with cleft, and a lower score to the tongue in the control group than in the group with unilateral cleft lip and palate. Regarding the electromyographic activity, there was no difference between the groups as to the protusion of the lips, but the percentage of the maximal activity used in the syllable emissions was greater in the group with isolated cleft palate than in the groups control and unilateral cleft lip and palate. As to the DDK, it was verified a greater number of emissions per second and a lower mean time between the emissions of the syllable ca in the control group compared to the group with unilateral cleft lip and palate and a greater number of emissions per second of the sequence pataca in the control group than in the group with with isolated cleft palate. Conclusion: In the investigated sample, the mobility of the lips was decreased in the groups with cleft and the mobility of the toungue was decreased in the group with unilateral cleft lip and palate compared to the group without cleft; an increased percentage of the maximal activity to produce the syllable pa was used in the group with the isolated cleft palate; the rate of the emission of the syllable ca was lower in the unilateral cleft lip and palate, as in the group with isolated cleft there were lower emissions of the sequence pa-ta-ca than in the group without cleft.

A retrospective study of breast milk feeding in infants with oral clefts

Rathwell, Elizabeth Mersereau Neel 20 February 2018 (has links)
OBJECTIVE: The goal of this study was to gather information from mothers’ of children born with orofacial clefts (OFC) in order to more accurately describe their early feeding experiences, from the time of diagnosis through the first six months of life. METHODS: We surveyed mother’s whose babies with OFC were treated at Seattle Children’s Hospital (SCH) Craniofacial Clinic and were born on or after 1/1/2013 through 12/31/2016. Survey questions were geared toward understanding overall difficulty with feeding, access to supplies for feeding, and methods and duration of any breast milk feeding. RESULTS: Eighty-two percent of mothers wanted to exclusively breastfeed for the first 16 weeks prior to the OFC diagnosis, of which 79% attempted breastfeeding and 74% attempted any breast milk feeding. Donor milk was used in 18% of mothers and 41% supplemented with formula in the delivery hospital. The majority of women were knowledgeable about facts of breastfeeding and 41% reported they received information from a lactation specialist in their delivery hospital. The level of stress reported by mothers stayed relatively the same over first 4 weeks of life and dropped by 16 weeks. The majority of women who used a breast pump pumped for 0 to 20 minutes in first week and then 0 to 30 minutes between weeks 4 to 16. Thirty percent of mothers reported receiving information specifically from a craniofacial nurse and craniofacial pediatrician before delivery and 36% reported receiving information from a craniofacial nurse and craniofacial pediatrician after their birth hospital stay. CONCLUSION: Initial study results of feeding practices, knowledge of breast milk feeding, and feeding experiences of mothers with babies born with OFCs show that most mother’s intended to exclusively breastfeed prior to their birth and that the majority of women were reasonably informed about the benefits of breastfeeding. We also found that after the delivery of their child with an OFC more mothers reported having difficulty with feeding and wanted to provide breast milk longer than they were able to do so. Once the data collection is complete the survey data will be stratified for prenatal versus postnatal diagnosis and also when a breast pump was obtained. This information and additional data will be collected from a second phase of the study, which is a medical chart abstraction to look at the child’s demographics and growth chart data for the first six months of life.

Rastreamento labial: aplicação em leitura labial. / Lip tracking: an application in lip reading.

Tupã Negreiros 07 November 2012 (has links)
Novas interfaces homem-computador têm sido pesquisadas a fim de se tornarem mais naturais e flexíveis. O rastreamento labial, foco deste trabalho, é parte deste contexto, podendo ser utilizado na detecção de emoções, bem como no auxílio ao reconhecimento de voz. Pode assim tornar-se um módulo inicial para a leitura labial, na criação de interfaces voltadas a deficientes auditivos. Os algoritmos disponíveis na literatura foram analisados e comparados, mostrando os prós e contras de cada método. Finalmente foi escolhido desenvolver uma técnica baseada em Active Appearance Model (AAM). O AAM gera um modelo a partir de um conjunto de imagens de treinamento, que pode ser utilizado no rastreamento labial de novas imagens. A técnica proposta baseia-se no uso de algoritmos genéticos para o ajuste do modelo, diferente, portanto, da técnica proposta originalmente pelo AAM. A convergência da técnica proposta foi extensivamente analisada, com a variação de parâmetros, buscando a análise de erro residual da função custo e sua relação com o tempo de convergência e erro de posição. / New human-computer interfaces have been researched to make them more natural and flexible. The lip tracking, emphasis of this work, is part of this setting it can be used for detecting emotions and to aid the speech recognition. It may well become an initial module for lip-reading, in the creation of interfaces directed to hearing impaired people. Algorithms available on literature are analyzed and compared, explaining the upsides and downsides of each method. Finally was chose to develop a technique based on Active Appearance Model (AAM). The AAM generates a model from a set of training images, which can be used in tracking of new lip images. The proposed technique is based on the use of genetic algorithms for fitting the model, different therefore of the technique originally proposed by AAM. The convergence of the proposed technique has been extensively analyzed with the variation of parameters, searching the error analysis of the cost function residual error and its relation to the execution time and position error.

Analysis of the maxillary dental arch after rapid maxillary expansion in patients with unilateral complete cleft lip and palate / Analysis of the maxillary dental arch after rapid maxillary expansion in patients with unilateral complete cleft lip and palate

Priscila Vaz Ayub 07 July 2014 (has links)
Objective: The aim of this study was to evaluate the dentoalveolar effects of rapid maxillary expansion in children with unilateral complete cleft lip and palate in comparison with non-cleft patients. Methods: The experimental group (EG) was composed of 25 patients with unilateral and complete cleft lip and palate (9 males and 15 females) with a mean age of 10.6 years. The control group (CG) comprised of 27 patients without cleft lip and palate (14 males and 13 females) with a mean age of 9.1 years. Dental models of the maxillary dental arch were obtained immediately preexpansion (T1) and 6 months post-expansion (T2) at the time of appliance removal. Digital dental models were obtained using the 3Shape R700 3D laser scanner (3Shape A/S, Copenhagen, Denmark). Transversal widths, arch perimeter, arch length, palatal depth, palatal volume, canine and posterior tooth inclination were digitally measured. Paired t-test was used to perform interphase comparisons and independent t-test to perform intergroup comparisons (p<0.05). Results: In the experimental group, the expansion produced a ignificant increase of all maxillary transverse measurements, palatal volume, arch perimeter and palatal depth while decreased the arch length. RME caused a buccal tip of posterior teeth in patients with UCLP. No differences were observed between experimental and control groups for all the measurements performed except for the intermolar distance (6-6), which showed a greater increase in patients with cleft. Conclusion: Rapid maxillary expansion showed similar dentoalveolar effects in children with UCLP and without oral clefts. / Objective: The aim of this study was to evaluate the dentoalveolar effects of rapid maxillary expansion in children with unilateral complete cleft lip and palate in comparison with non-cleft patients.

Lesões actinicamente induzidas em lábio inferior de pescadores: estudo clínico, cito e anatomopatológico / Actinic lesions in fishermen lower lip: clinical, cytopathological and histopathological analysis

Marques, Karine Piñera 20 October 2008 (has links)
Este estudo propôs-se a avaliar lesões de lábio inferior de pescadores nas praias de Florianópolis, Santa Catarina, Brasil, através de análise clínica, cito e anatomopatológica. Foi realizada análise citológica de esfregaços do lábio inferior de todos os pescadores (125) cuja celularidade foi adequada (83,2% dos casos). Em 16 pescadores a avaliação clínica indicou a necessidade de biópsia, nos quais observaram-se 4 casos de lesão maligna (3,2%) e 12 de graus variados de displasia (9,6%). A análise citológica dos esfregaços não foi capaz de detectar nenhuma das alterações displásicas ou malignas diagnosticadas nas biópsias. Todos os casos em que as características clínicas indicaram a necessidade de biópsia revelaram alterações significativas na análise histopatológica. Concluiu-se que a incidência de lesões displásicas e malignas é alta na população de pescadores estudada e que está fortemente associada às manifestações clínicas correspondentes à alteração na delimitação entre vermelhão do lábio e pele e aumento da consistência à palpação, não sendo a citologia esfoliativa adequada, apenas em bases morfológicas, para avaliação de queilite actínica e câncer de lábio. / This study proposed to evaluate the injury of lower lip of fishermen on the beaches of Florianópolis, Santa Catarina, Brazil, through clinical, cytopathological and histopathological analysis. Cytological examination was performed on smears of the lower lip of all fishermen (125) whose cellularity was satisfactory in 83,2% of the cases. On 16 fishermen the clinical evaluation indicated the need of biopsy. In 4 cases (3.2%) it was observed malignant lesions and in 12 cases (9,6%) it was observed differents degrees of dysplasia. The cytological analysis was unable to detect any of the dysplastic changes or malignancies diagnosticated in the histopathological study. In all cases where the clinical features indicated the need of biopsy it had significant changes in microscopic analysis. It was concluded that the incidence of malignant and premalignant lesions is high in this fishermen studied population, which is strongly associated with the clinical manifestations corresponding to blurring of vermilion margin and infiltration, and the exfoliative cytology is inadequate, only in morphological basis, to detect dysplastic alterations and cancer of the lip.
