Made available in DSpace on 2015-12-06T22:54:36Z (GMT). No. of bitstreams: 0 Previous issue date: 2006 / Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq) / Objetivo: Avaliar a efetividade da Mitomicina C (MMC) tópica na prevenção e retardo da formação de sinéquias e estenose após manipulações endoscópicas funcionais dos seios paranasais em humanos. Forma de Estudo: Randomizado controlado. Método: 14 pacientes portadores de Rinossinusite Crônica foram submetidos a cirurgias endoscópicas funcionais dos seios paranasais, ao final das quais era colocado cotonóide neurocirúrgico com 1 ml de Mitomicina C (1,0 mg/ml) em um dos meatos médios e outro com 1 ml de solução salina no meato médio contralateral, que servia de controle, ambos por 5 minutos, de forma randomizada, sem que o autor tivesse conhecimento dos lados. O seguimento foi realizado pelo autor, cego em relação aos lados. Foi avaliada a presença de sinéquias em meatos médios e estenoses nas antrostomias. Resultados: Um total de 12 sinéquias (42,86 %) foram identificadas em 10 dos 14 pacientes (p = 0,57). Oito pacientes tiveram sinéquias unilaterais e dois, bilaterais. Dentre as 8 sinéquias unilaterais, somente 1 ocorreu no lado com MMC contra 7 no lado controle (p = 0,07). Ao final de um ano, no grupo MMC, houve 3 (21,43 %) sinéquias contra 9 (64,29 %) no grupo controle (p = 0,054). No lado com MMC todas as 3 (21,43 %) sinéquias foram parciais, enquanto no grupo controle houve 4 (28,57 %) parciais e 5 (35,71 %) totais (p = 0,025). Não houve sinéquias totais no grupo MMC (p = 0,034). Em relação às antrostomias, 1 (7,14 %) ipsilateral à MMC teve estenose, enquanto no grupo controle foram 9 (64,29 %) (p = 0,004). No grupo com MMC a única ocorrência (7,14 %) foi da forma parcial, enquanto que no controle foram 4 (28,57 %) parciais e 5 (35,71 %) totais (p = 0,006). Não houve diferença em relação ao tempo médio de ocorrência de sinéquias entre os grupos (p= 0,055), somente para o tipo total (p = 0,034). O tempo médio para aparecimento de estenoses nas antrostomias foi maior no grupo MMC (p = 0,0015), assim como a média para aparecimento de estenose total (p = 0,016). Conclusão: A Mitomicina C não foi eficaz na prevenção e retardo da formação de sinéquias parciais, porém, preveniu e retardou a formação de sinéquias totais e estenoses nas antrostomias, no pós-operatório de cirurgia endoscópica funcional dos seios paranasais em humanos. Tendo em vista a facilidade de seu uso na forma tópica, em dose única intra-operatória, com poucos efeitos colaterais, somados ao benefício que ela pode trazer, nossos resultados apresentam uma nova perspectiva para a diminuição dos insucessos da cirurgia endoscópica funcional dos seios paranasais. / Purpose: To assess the efficacy of topical Mitomycin C (MMC) in the prevention and delay of synechiae and stenosis formation after functional endoscopic sinus surgery in humans. Method: At the end of functional endoscopic sinus surgery in 14 patients, a cotton pledget soaked in 1 mL of 1 mg/mL MMC was randomly placed into the middle meatus of one nasal cavity for 5 minutes and an identical saline-soaked pledget was placed in the contralateral side in each patient. The author was blinded for the side of the substances. Patients were followed postoperatively by a blinded observer for the presence of synechiae in the middle meatus and stenosis of the maxillary antrostomy. Synechiae were rated as partial when not totally closed, and total when completely closed. Stenosis were rated as partial when smaller than a diameter of 3 mm, and total when completely closed. Results: 12 synechiae (42,86 %) were identified in 10 of 14 patients (p = 0,057). They were unilateral in 8 patients and bilateral in 2. Unilateral synechiae were observed on only 1 side treated with MMC and 7 controls (p = 0,07). After a follow-up of 1 year, 3 sides (21,43 %) treated with MMC and 9 controls (64,29%) had synechiae (p = 0,054). On the MMC side all of them were partial, while on the control side 4 (28,57 %) were partial, and 5 (35,71 %) were total (p = 0,025). One side (7,14%) treated with MMC had stenosis, compared with 9 (64,29%) controls (p = 0,004). The time of occurrence of synechiae was not statistically different between the groups (0,055). However, the time of occurrence of the total type was longer in the MMC group (p = 0,034). The medium time of appearance of stenosis was statistically longer in the MMC group (p = 0,0015). All patients improved their symptoms at the end of our study. Moreover, none needed revision procedure or referred adverse effects. Conclusion: MMC was not efficient in the prevention and delay of synechiae formation. However, it was efficient in preventing and delaying total synechiae and stenosis formation after functional endoscopic sinus surgery in humans. Our results present a new perspective to achieve favorable success rates in functional endoscopic sinus surgery. / BV UNIFESP: Teses e dissertações

Projevy delikvence na ZŠ a možnosti převýchovy mladistvých delikventů / Deliquent behaviour on primary schools and possibilities of reeducation of youthful deliquents.

ŽEMLIČKOVÁ, Elena January 2007 (has links)
The subject of my thesis reflects contemporary all-society problem of patholo-gic aspects of behaviour of young people. Theoretical part of my thesis deals with term deliquency, its determinants and also with techniques of solving pathologic phenomenon both in our republic and foreign countries. In practical part you can find survey about socially pathologic features, the im-portance of family background and leisure time activities of teenagers between 13-15 years. This survey was made by questionaries. The aim of my thesis is to find out the impact of family background on patho-logical behaviour of young people, their free time activities etc.

Názory veřejnosti na problematiku nových náboženských hnutí a jejich možná rizika na Českobudějovicku a Klatovsku / Public opinions about the problem of new religious movements and their possible danger in the regions of Ceske Budejovice and Klatovy

JINDROVÁ, Markéta January 2009 (has links)
The problem of new religious movements is quite a current topic. Therefore, I have decided to write my thesis about this subject. The theoretical part contains the definitions of the basic terms, the characteristics of new religious movements, their catagories and characteristics of their victims, the context of new religious movements and the law, as well as the connection of religious groups and socially-pathologic phenomena. Each of the phenomena is attached to concrete examples of the social groups involved. Both qualitative and quantitative research was employed in the practical part. The methods that have been used to obtain this information were a survey and and interview, as well as the anaylsis of the data and content. One of the files for the survey was collected in the Klatovy Region, while the other was gathered from the people of the Ceske Budejovice Region. Thus, the acquired data were compared in order to reach the aim of the work. The two aims were set based upon the secondary data and one hypothesis was declared for each. The first aim, which was `to find out the public opinion on the problems of new religious movement{\crq}, was connected with the hypothesis `although the public is not sufficiently informed about the religious cults in the region, they are perceived as negative{\crq}. The other aim was to map the socially-pathological phenomena connected with the activity of the movements in these particular regions. Regarding that research, which was qualitative, the hypothesis was declared on the ground of the acquired data. Hypothesis No. 1 was verified. Based on an interview with local policemen, the other hypothesis was set: Although information about the socially-pathological phenomena connected with the activity of the movements reached the public, the Police of the Czech Republic do not have evidence of any crime of that character in the given regions. A booklet was put together, based upon the acquired information, giving the overall information about new religious movements, their characteristics and possible risks. In my opinion, the aim of my thesis was met. The research showed that the public awareness of new religious cults is rather low and the information is mostly distorted. The results of my work may serve as further insight into this problem and, threby it may become a stimulus to raise the state of awareness in this sphere.

Orientador: Carmen Silvia Passos Lima / Dissertação (mestrado) - Universidade Estadual de Campinas, Faculdade de Ciencias Medicas / Made available in DSpace on 2018-08-06T13:26:41Z (GMT). No. of bitstreams: 1 Lourenco_GustavoJacob_M.pdf: 17814526 bytes, checksum: 4b05f16607bfec15eee0533ac8440e33 (MD5) Previous issue date: 2006 / Resumo: A angiogênese é um importante processo para o desenvolvimento e progressão do câncer de mama esporádico (CME). Há evidências de que as células tumorais podem produzirproteínas antiangiogènicas como a endostatina (ES). A ES é codificada pelo gene COL18A1. Recentemente, um polimorfismo do gene COL18A1, o D104N, foi associado ao aumento do risco de ocorrência do adenocarcinoma de próstata. Considerando que não há descrições sobre a influência do polimorfismo D104N na susceptibilidade ao CME, este foi definido como o objetivo do estudo. Assim, o DNA genômico de 181 mulheres com CME e 448 controles foi analisado por meio da reação em cadeia da polimerase e digestão enzimática com a enzima Msél. O método ELISA foi utilizado para a quantificação da ES sérica de 118 pacientes com CME e 158 controles. As amostras dos controles estiveram no Equilíbrio de Hardy-Weinberg (X = 2,15; P= 0,14). Em contraste, as amostras das pacientes não confirmaram a expectativa de Hardy-Weinberg no lócus D104N do gene COL18A1 (X2= 22,87; P< 0,0001). Observamos que a freqüência do polimorfismo 104NN foi maior em pacientes do que em controles (2,8% vs 0,0%; respectivamente). Os indivíduos com o genótipo NN apresentaram um risco infinitamente maior de ocorrência da doença do que aqueles com os outros genótipos (P= 0,003). As freqüências do polimorfismo 104NN foram similares em pacientes estratificados por variáveis clínicas (idade, raça, idades da menarca, menopausa, da primeira gestação a termo, lactação, terapia de reposição hormonal e hábito de fumar) e laboratoriais (histologia, graus histológico e nuclear, padrão dos receptores de estrogênio e progesterona e estágio TNM do tumor). A mediana das concentrações da ES foi maior em pacientes do que em controles (P< 0,001). Valores similares foram encontrados em pacientes (P> 0,759) e controles (P= 0,535) estratificados por genótipos. Os nossos resultados sugerem que o polimorfismo 104NN do gene COL18A1 está associado à susceptibilidade do CME, possivelmente devido à anormalidade funcional da proteína. / Abstract: Angiogenesis is an important step in sporadic breast cancer (SBC) development and progression There is evidence that neoplastic cells play a role in the generation of endogenous antiangiogenic proteins, such as endostatin (ES). ES is codified by the COL18A1 gene. Recently, a COL18A1 polymorphism (D104N) was associated with increased risk for the prostatic adenocarcinoma. Considering that it is unknown whether the D104N polymorphism of the COL18A1 gene alters the risk for SBC, this was the aim of this study. Thus, genomic DNA from peripheral blood of 181 SBC women and 448 controls were analysed using the polymerase chain reaction followed by restriction endonuclease digestion with Msel. ELISA for quantification of ES was performed in serum from 118 SBC woman and 158 controls. Controls' samples were in Hardy-Weinberg equilibrium (X2= 2.15, P= 0.14). In contrast, patients' samples did not confirm the Hardy-Weinberg expectations at the D104N locus (X2= 22.87, P< 0.0001). We observed a higher frequency of 104NN polymorphism in SBC patients than in controls (2.8% vs 0.0%, respectively). Individuals with the 104NN polymorphism had an infinite risk for disease (P= 0.003) when compared with those with other genotypes. The frequencies of the 104NN polymorphism were similar in patients stratified by clinical (age, ethnical origin, ages of menarche, menopause, first full-term pregnancy, lactation, hormone replacement therapy, and smoke habit) and laboratory variables (tumour histology, histological and nuclear grades, status of estrogen and progesterone receptors, and stage TNM of the tumour). The median values of ES was higher in patients than in controls (P< 0.001). Similar median values of ES were seen among patients (P> 0 759) and controls (P= 0.535) stratified by genotypes However, differences in clinical and laboratory manifestation and levels of ES may not have reached statistical significance due to the small number of individuals with the 104N allele, enrolled in study. Our results suggest that the 104NN genotype of the COLI8AI gene is associated with SBC susceptibility, possibly due to an abnormal ES function. / Mestrado / Clinica Medica / Mestre em Clinica Medica
