Análise do perfil mole facial frente ao avanço cirúrgico de maxila em pacientes com fissuras labiopalatinas / Analysis of the facial soft tissues following surgical maxillary advancement in cleft lip and palate patients

Gustavo Lara Achôa 04 June 2008 (has links)
Objetivo: Avaliar as alterações cefalométricas induzidas em tecidos duros e moles em pacientes com fissuras transforame incisivo bilaterais (FTIB) submetidos ao avanço cirúrgico da maxila e o efeito de tal procedimento sobre o perfil mole. Modelo: Estudo retrospectivo que comparou um tempo pré-operatório imediato a outro pós-operatório mínimo de seis meses, por meio de telerradiografias cefalométricas em norma lateral e cefalometria computadorizada, de indivíduos com fissuras labiopalatinas. Local: Clínica de Odontologia, HRAC/USP. Participantes: 8 pacientes do sexo feminino e 17 do sexo masculino, entre 15 e 35 anos, com média de 20,56 anos de idade, que foram submetidos ao tratamento de reabilitação com cirurgia ortognática envolvendo avanço de maxila. Variáveis: Diferenças entre os períodos pré e pós-operatório de pontos cefalométricos definidos em maxila e perfil mole, Ângulo Naso-Labial (ANL) e distâncias representativas do comprimento (Sn-Sts) e espessura (Ls-Sts) labial superior, além das proporções da movimentação do tecido mole em relação à movimentação do tecido duro de suporte. Resultados e Conclusão: As alterações cefalométricas no sentido horizontal ocorreram em todos os pontos estudados, em tecido duro e mole; no sentido vertical, apenas os pontos Pró-nasal (Prn), Subnasal (Sn) e A\' tiveram alterações significantes; o aumento significante do ANL e Sn-Sts também foi observado. As proporções entre a movimentação óssea e a acomodação do tecido mole do perfil facial são menores que as proporções obtidas nos estudos similares em pacientes com outros tipos de fissura e pacientes sem fissuras, porém no mesmo sentido e direção. / Objective: To assess cephalometric changes in hard and soft tissues of bilateral cleft lip and palate (BCLP) patients following surgical maxillary advancement and its effect over the soft tissue profile. Design: Retrospective study which compares an immediately pre surgical to a post surgical moment, at least six months later, through cephalometric lateral radiographs and a cephalometry computer program, of individuals with cleft lip and palate. Setting: Clinic of Dentistry, HRCA/USP. Subjects: 8 women and 17 men, from 15 to 35 years old and mean age of 20.56, underwent orthognathic surgery with maxillary advancement during the rehabilitation treatment. Variables: Changes between different cephalometric landmarks from pre surgical to post surgical periods in hard and soft tissue of maxilla, Nasolabial angle (NLA) and distances representing the length (Sn-Sts) and thickness (Sts-Ls) of the upper lip, besides the ratios of soft tissue changes relative to hard tissue movements. Results and Conclusion: Horizontal cephalometric changes happened to all of the studied landmarks in both maxilla and soft tissue profile; vertically, only Pronasale (Prn), Subnasale (Sn) and A\' showed significant changes; the significant increasing of NLA and Sn-Sts also was observed. The ratios of facial profile soft tissue changes relative to bone movement were smaller than ratios observed in patients with other cleft types and patients with no clefts, however, this changes remain in the same directions.

\"Alterações do perfil facial decorrentes das cirurgias de avanço e impactação da maxila\" / Facial soft tissue changes derived from maxillary advancement adn impaction.

Luis Fernando Corrêa Alonso 16 March 2007 (has links)
O presente estudo avaliou por meio de teleradiografias em norma lateral as alterações do perfil facial frente à cirurgia Le Fort I com avanço e impactação da maxila utilizando fixação rígida e sutura V-Y, em 18 pacientes, com de classe III, leucoderma, com média de idade de 23 anos e 7 meses. As radiografias foram obtidas com os dentes em máxima intercuspidação, lábios em repouso, na fase précirúrgica imediata (M1) e 1 ano após a cirurgia (M2). Para responder o objetivo do estudo os valores das estruturas ósseas e tegumentares foram comparadas antes e depois da cirurgia por meio do teste t de Student pareados e foi aplicado o teste de correlações de Pearson entre as medidas ósseas e tegumentares de interesse. As relações entre as variações foram avaliadas com uso de regressão linear. Concluí-se após a análise dos resultados que não houve alteração estatisticamente significativa no sentido vertical, para os valores dentoesqueléticos e tegumentares estudados, exceto para o valor do ângulo do plano mandibular. Entretanto, houve correlação direta das alterações entre eles, exceto para os valores do plano mandibular com a espinha nasal anterior e posterior e do ângulo nasolabial com o incisivo superior. No sentido horizontal, houve alteração estatisticamente significativa entre os valores dentoesqueléticos e tegumentares relacionadas à maxila e não houve entre os valores relacionados à mandíbula. A previsibilidade numérica das alterações tegumentares decorrentes do avanço e impactação da maxila está sujeita a alterações individuais. / The purpose of this study was to determine retrospectively, by means of lateral cephalograms, the postsurgical changes in the facial soft tissue profile in class III patients (n=18) submitted to Le Fort I osteotomy, for maxillary impaction and advancement within the ?V-Y? suture. Caucasian individuals constituted the sample, and average age was 23 years old and 7 months. The cephalograms were obtained in maximum intercuspation with the lips at rest. The patients were evaluated in two times, the first period was in the immediate pre-surgical (M1) and, one year after the surgical procedure (M2). In order to answer the purpose of this study, skeletal and facial soft tissue measurements were compared before and after the surgery, by means of paired Student t tests, and the Pearson?s correlation coefficient for skeletal and facial soft tissue relevant measurements, using the variations (after and before) between the values. The relationship between the significant variations was evaluated by means of linear regression analysis. The findings indicated that there was not statically significant difference in the vertical plane, for the studied dentalskeletal and facial soft tissue values, exception for the value of the mandibular plane angle. However, there was direct correlation between then, except for the values of the mandibular plane angle-ANS; mandibular plane angle-PNS, and nasolabial angleupper incisors. In the horizontal plane, there was statically significant difference between the dental-skeletal values and facial soft tissue, related to the maxilla and there was not in the values related to the mandible. The numerical prediction of the facial soft tissue changes occasioned by the impaction and maxillary advancement is subject to individual responses.

Amon Carter: The Founder of Modern Fort Worth, 1930-1955

Cervantez, Brian 05 1900 (has links)
From 1930 to 1955, Amon Carter, publisher of the Fort Worth Star-Telegram, exerted his power to create modern Fort Worth. Carter used his stature as the publisher of the city's major newspaper to build a modern city out of this livestock center. Between 1930 and 1955, Carter lobbied successfully for New Deal funds for Fort Worth, persuaded Consolidated Aircraft to build an airplane plant in the city, and convinced Burlington Railways to stay in the city. He also labored unsuccessfully to have the Trinity River Canal built and to secure a General Motors plant for Fort Worth. These efforts demonstrate that Carter was indeed the founder of modern Fort Worth.

Community Gardening: a Novel Intervention for Bhutanese Refugees Living in the USA

Gerber, Monica M. 08 1900 (has links)
Since 2008, the United States (USA) has resettled thousands of Bhutanese refugees, providing brief financial support and pathways to citizenship. Despite the efforts of governing bodies and voluntary agencies which facilitate resettlement, many refugees struggle with adapting to the vastly different lifestyle, economy, language and social structures. In particular, effectively addressing psychological needs of this population is a challenge for service providers operating within an expensive health care system based on Western constructs of mental health. In response to this challenge, refugee resettlement agencies throughout the country use community gardens to promote psychological healing, self-sufficiency, community engagement, and a return of human dignity. Though success of these programs is being shared in the media, there has yet to be empirical data examining their impact. The current study tested whether Bhutanese refugee engagement in a community garden impacts symptoms of depression, anxiety, PTSD and somatic complaints. The study also investigated whether community gardening is associated with perceptions of social support and adjustment to life in the United States. Quantitative and qualitative data was collected from 50 adult Bhutanese refugees in Fort Worth, Texas. Gardening was significantly related to increased social support overall, a key factor in overall functionality within communal cultures; and specifically perceived tangible support was increased. A significant effect of gardening was also found for adjustment. Although a significant effect was not found for psychological and somatic symptoms, there is still evidence of effects on somatic complaints. Varying results from quantitative and qualitative data warrant further investigation into the nuanced work of clinical research and advocacy with refugee populations.

Citizen perspectives on community policing : an examination of theories, philosophy and principles at work

Moore, Talmadge N. January 2001 (has links)
The purpose of this naturalistic qualitative inquiry was to develop a more complete understanding of the process of implementing community policing from the citizen participants' perspective. While an abundance of literature exists on the topic of community policing, with the exception of several survey and evaluation efforts, little examination of this topic has been conducted that devoted exclusive attention to citizen participation in this style of policing. It was citizen participant descriptions that formed the basis for this examination. The present study also examined the theoretical support for community policing by comparing the citizen descriptions of this concept to the component parts of critical social science (Fay, 1987), normative sponsorship theory (Sower, et al., 1957) and community education for development (Compton & McClusky, 1980).A purposive sample was utilized to examine this topic. This sample was composed of citizens (N = 71) from Fort Wayne, Indiana and Fort Worth, Texas who had participated with their respective municipal police departments in implementing community policing. The community policing efforts in these cities had been in existence since the early to mid 1990s. The sample was composed of citizens that came from different geographic areas of their respective cities, and who had spent at least one year working with assigned police officers and community groups. A questioning route was developed and participants were interviewed in focus group settings. Data analysis identified seven themes from the transcribed interviews. These themes were: (a) partners; (b) community education; (c) neighborhood associations; (d) involvement with government; (e) problem solving; (f) frustration with the city administration and (g) communication and managing community policing.The research found that relatively successful community policing efforts rely upon structured neighborhoods, ample community education, an emphasis on problem solving, open communication and strong support from the upper levels of municipal government. Many of these findings were supported by the literature in the field. Additionally, the theories purported to support community policing were found to confirm the citizens' experiences in these cities. / Department of Educational Leadership

A study of the impact of unconventional sources within a large urban area: evidence from spatio-temporal assessment of volatile organic compounds.

Matin, Maleeha 05 1900 (has links)
Conventional sources of emissions have been a prime target for policymakers in designing pollution control strategies. However, the evolution of shale gas activities is a growing concern over the impact of unconventional sources on urban and regional air quality. Owing to the development of Barnett Shale production, the fast-growing Dallas-Fort Worth (DFW) metroplex has encountered both types of these emissions. Oil and gas activities result in emissions of ozone precursors, notably volatile organic compounds (VOC). The major objective of this study was to evaluate the spatio-temporal distribution of VOC in order to highlight the influence of unconventional emissions. The study utilized measurements from automated gas chromatography (AutoGC) monitors to analyze the patterns of the total non-methane organic compounds (TNMOC) and relative contributions from marker species of traffic versus oil and gas activities. In this study, data from 2001-2014 was obtained from the Texas Commission on Environmental Quality (TCEQ) for fifteen monitoring sites within the North Texas region. With over a thousand wells in a 10 mile radius, two of the rural sites measured twice as much TNMOC as compared to the urban site in Dallas. Source apportionment analysis was conducted using Positive Matrix Factorization (PMF) technique. The target site located in the urban zone resolved an eight factor model. Natural gas signature was the dominant source of emission with a 52% contribution followed by 31% from two separate traffic-related sources. Considering ethane to be the dominant species in oil and gas emissions, it was observed that the rising ethane/NOx ratio correlated with increasing annual average ozone post-2007. In this period, higher concentration of ozone was found to be associated with stronger winds from the Barnett Shale area – a region that did not seem to contribute to high ozone during 2001-2007. With traffic emissions having flattened over the years, the recent increase in oil- and gas-related emissions has a negative impact on the air quality in this area. Results indicate that the area has failed to observe a declining trend in ozone despite effective reductions in NOx and traffic-related VOC emissions. The findings of the study would be helpful in proper evaluation of the ozone-forming potential of unconventional VOC emissions. Although these emissions may not be strong enough to cause harm through direct exposure, underestimating their potential towards ozone formation could hinder the progress in ozone attainment in growing urban areas. After all, a major portion of the study area continues to be in nonattainment of the EPA designated ozone standards. The study therefore draws the attention of policymakers towards the new influx of emissions that have emerged as a powerful source within the DFW metropolitan area.

The 1901 Fort Wayne, Indiana City Election: A Political Dialogue of Ethnic Tension

Brown, Nancy Eileen January 2013 (has links)
Indiana University-Purdue University Indianapolis (IUPUI) / In 1901, three German American candidates ran for the office of mayor in Fort Wayne, Indiana. The winner, Henry Berghoff, had emigrated from Germany as a teenager. This thesis examines the election discourse in the partisan press for signs of ethnic tension. The first chapter places Fort Wayne in historical context of German immigration and Indiana history. The second and third chapters investigate the editorial pages for evidence of ethnic tension. I also reference a few articles of an editorial nature outside of the editorial pages. The second chapter provides background information about the election and examines indications of the candidates’ ethnicity and references to the German language papers. The third chapter considers the editorial comment about Germany, the intertwining of ethnicity and the issues, and ethnic name-calling. In order to identify underlying bias for or against Germany and to better understand the context of the references to German ethnicity, the fourth chapter explores the portrayal of Germany in the Fort Wayne papers.

Use of Instructional Resources by Community Junior College Occupational Instructors

Lolley, John L. 05 1900 (has links)
The purpose of this study was to develop information and understanding concerning the use of instructional resources, including library materials, by community junior college vocational-technical instructors. The study sought to determine whether the kinds and amounts of instructional resources used by vocational technical instructors in their courses were related to their: (a) level of formal education, (b) number of courses in Higher Education completed, (c) years of teaching experience, and (d) teaching status (full or part-time). Further, the study sought to determine whether the attitudes toward use or non-use of the library were related to such instructor characteristics. The analyses of the data revealed that vocational technical instructors at Tarrant County Junior College utilized a wide variety of instructional resources in their courses. Instructional resources used in at least 50 percent of vocational-technical courses were: audio-visual materials, 88 percent; departmental books, 73 percent; personally owned books, 72 percent; manufacturers' literature other than service manuals, 63 percent; information from notes of previously taken courses, 63 percent; departmentally prepared syllabi, 58 percent; personally owned journals, 56 percent; self-prepared syllabi, 53 percent; manufacturers' service manuals, 52 percent; and association publications, 50 percent.
