Eficácia do pamidronato na melhora da dor e da qualidade de vida em pacientes com displasia fibrosa óssea

Pechutti, Monise da Silva January 2018 (has links)
Orientador: Gláucia Maria Ferreira da Silva Mazeto / Resumo: Introdução: A displasia fibrosa óssea (DFO) é uma doença rara, de origem genética somática, não hereditária, caracterizada por formação de tumores ósseos, resultando em dor óssea, deformidade e fraturas. Não há tratamento curativo e a cirurgia tem como finalidade a correção de fraturas e descompressão nervosa. A dor, principal sintoma desta doença, é fator limitante para as atividades diárias e prejudica a qualidade de vida. Para o alívio da dor óssea, os bisfosfonatos desempenham fundamental importância. Até o momento, não há consenso sobre o bisfosfonato mais adequado, o tempo ou o número ideal de ciclos de aplicação da medicação. Vários marcadores bioquímicos vêm sendo propostos no seguimento dos pacientes, ainda também sem definição sobre o mais adequado. A adequada quantificação de parâmetros relacionados à resposta terapêutica, particularmente da dor e da qualidade de vida, podem propiciar a monitorização objetiva e desempenhar papel norteador na abordagem destes pacientes. Objetivos: Avaliar a eficácia do pamidronato em pacientes com DFO, na melhora da dor óssea e da qualidade de vida. Casuística e métodos: Foram convidados a participar do estudo todos os pacientes portadores de DFO atendidos nos Ambulatórios de Endocrinologia, Ortopedia e Pediatria do Hospital das Clínicas da Faculdade de Medicina da Universidade Estadual Paulista “Júlio de Mesquita Filho” Unesp. Este estudo observacional, avaliou pacientes com DFO de forma prospectiva, por meio de coleta de dados dos...

There is no curative treatment, and the only purpose of surgery is to correct fractures and nerve decompression. Pain is the main symptom, and limit daily activities impairing quality of life. For the relief of bone pain, bisphosphonates play a fundamental role. Until this moment, there is no consensus on which is the most adequate bisphosphonate to be used, the ideal timing of the application and the number of optimal medication application cycles. Several biochemical markers have been proposed in the follow-up of these patients, but yet there is no definition of the most appropriate. Proper quantification of parameters that evaluate therapeutics response, in particular pain and quality of life, can propitiate objective monitoring and play a guiding paper into approach these patients. Objectives: To evaluate the effect of using bisphosphonates in patients with FD, with perception of the improvement in relieving bone pain and quality of life. Methods: All the patients with FD attended in the Ambulatories of Endocrinology, Orthopedics and Pediatrics of the Hospital of the Medical School of Universidade Estadual Paulista “Júlio de Mesquita Filho” (Unesp) were invited to participate the research. This observational study, evaluate FD patients in a retrospective form, gathering medical r... (Complete abstract click electronic access below) / Mestre

Displasia broncopulmonar: incidência e fatores de risco neonatais para recém-nascidos prematuros de muito baixo peso nascidos em hospital universitários de Maceió-2009 / Bronchopulmonary Dysplasia: incidence and neonatal risk factors in very low weight premature newborrn in universitary hospitals of Maceió-2009

Moura, Katharina Vidal de Negreiros [UNIFESP] 29 September 2010 (has links) (PDF)
Made available in DSpace on 2015-07-22T20:49:52Z (GMT). No. of bitstreams: 0 Previous issue date: 2010-09-29 / Objetivos: determinar a incidência de displasia broncopulmonar durante o período de um ano (março de 2009 a fevereiro de 2010) e analisar os fatores de risco neonatais associados ao desenvolvimento da doença em serviços públicos de referência para alto risco neonatal em Maceió, o Hospital Universitário Prof. Alberto Antunes e a Maternidade Escola Santa Mônica. Métodos: foram registrados dados de todos os prematuros de muito baixo peso admitidos nas duas instituições durante um ano. O diagnóstico de displasia broncopulmonar foi estabelecido naqueles prematuros com necessidade de oxigênio aos 28 dias de vida. A incidência foi calculada dividindo-se o número de casos pelo total de prematuros de muito baixo peso das duas maternidades, durante o período do estudo. Foram feitas análises das variáveis associadas com o teste do Quiquadrado, para as categóricas, e o teste T de Student ou Mann-Whitney para as numéricas. Para prever o valor dessas variáveis foi realizada a análise de regressão logística. Resultados: foram admitidos nas duas instituições 244 prematuros de muito baixo peso. A incidência observada foi 22,1%. Destes, 54 evoluíram com a doença e 94 não a apresentaram. Houve diferenças quanto às médias de peso dos grupos (1050g com displasia e 1275g sem displasia) e quanto às médias de idades gestacionais (30 semanas com displasia e 32 semanas sem a doença). Fizeram uso de ventilação mecânica 94% dos prematuros com displasia e 45,8% sem displasia, com p<0,01. Também houve associação com uso de surfactante no grupo com displasia (98% com e 71,7% sem displasia, com p<0,01). O modelo de regressão logística foi preditivo em 70% para ventilação mecânica ao nascer (RR=2,04; IC 95%: 1,62-2,55) e peso ao nascer inferior a 1000g (RR=1,89; IC: 1,19-3,00). Conclusões: a incidência de DBP foi similar à encontrada na literatura. Houve associação com, baixa idade gestacional, uso de surfactante, baixo peso ao nascer e ventilação mecânica, sendo esses dois últimos preditivos para a doença. / Objectives: To determine the incidence of bronchopulmonary dysplasia in the period of one year (from March 2009 to February 2010) and analyze the associated neonatal risk factors to the development of the disease in Public Services in two references of high risk newborn in Maceió, the “Hospital Universitário Alberto Antunes” and the “Maternidade Escola Santa Mônica”. Methods: All very low birth weight preterm infants who were admitted in the both institutions were recorded during one year. The diagnosis was established in those preterm infants who needed oxygen at 28 days of life. The incidence was calculated by dividing the number of cases by the total number of preterm births in both hospitals during the study period. The associated variables were analysed with the “Chi-square” test and the T test of Student or Mann-Whitney. Logistic regression analysis was performed to predict the value of those variables. Results: 244 RNMBP were admitted in both institutions. The incidence was 22.1%. 54 evolved with bronchopulmonary dysplasia and 94 without. There were differences regarding the average weight of the groups (1050g with and 1275g without dysplasia)) and also as to the gestational age (30 weeks with BPD and 32 weeks without the disease). 94% of the prematures with and 45,8% without the disease made use of mechanical ventilation, with p<0,01. There were association with surfactant in the group with bronchopulmonay dysplasia (98% with and 71,7% without displasia, com p<0,01). The logistic regression model was predictive in 70% of mechanical ventilation at birth (RR=2,04 IC 95% 1,62-2,55) and weight lower than 1000g (RR=1,89 IC 95% 1,19-3,00).Conclusions: The incidence of DBP was similar to the literature. There were association with low weight in born, with low gestational age, use of surfactant and mechanical ventilation. Mechanical ventilation and weight lower than 1000g were predictive for the disease. / TEDE / BV UNIFESP: Teses e dissertações

Análise da prevalência das displasias cervicais e da infecção pelo papilomavírus humano em mulheres com lúpus eritematoso sistêmico / Analysis of cervical dysplasia and woman papillomavirus infection prevalence among women with systemic lupus erythematosus

Evandro Mendes Klumb 01 June 2010 (has links)
O lúpus eritematoso sistêmico (LES) que é doença auto-imune com prevalência maior em mulheres, determina lesões potencialmente muito graves em diversos órgãos. Seu tratamento é feito habitualmente com corticosteróides e agentes citostáticos, sendo esses últimos responsáveis não só por um aumento na freqüência de infecções, mas também de neoplasias, principalmente as hematológicas e as relacionadas às infecções virais. Estudos realizados em mulheres com LES, evidenciaram maior incidência de displasias cervicais, principalmente as pré-malignas, contudo poucos, pesquisaram especificamente o papiloma vírus humano (HPV) e sua associação com o uso dos imunossupressores. Considerando que a infecção pelo HPV é a doença sexualmente transmissível de maior prevalência no mundo e, que esse vírus é o agente etiológico do câncer cervical (a segunda neoplasia mais prevalente em mulheres), este estudo foi desenhado com o objetivo de identificar a freqüência da infecção pelo HPV e das displasias cervicais em mulheres com LES incluindo a análise dos fatores de risco clássicos e o uso de imunossupressores. Neste estudo foram selecionadas 177 pacientes com LES e, 244 mulheres sem LES e sem queixas e/ou doenças ginecológicas conhecidas, atendidas no ambulatório de ginecologia do HUPE-UERJ ou da Policlínica Piquet Carneiro-UERJ (grupo controle). Todas as mulheres incluídas, foram previamente informadas e assinaram termo de consentimento livre e esclarecido, aprovado pelo Comitê de Ética em Pesquisa do HUPE-UERJ. A pesquisa do HPV e genotipagem foi feita por reação em cadeia da polimerase e a citopatologia, por coloração de Papanicolaou e análise por dois patologistas. As pacientes com LES apresentaram freqüência da infecção por HPV (20,2%) e de displasias cervicais (22,6%) significativamente mais elevadas que as encontradas no grupo controle (Chi quadrado, P<0,05), apesar de apresentarem em média, menos fatores de risco clássicos para essa infecção (P<0,05). O uso prolongado de imunossupressores, aumentou em três vezes a chance de infecção por HPV dentre as pacientes com LES (cuja prevalência foi de 28,2%). Ainda em referência às pacientes com LES, as que apresentavam HPV, haviam feito uso de doses cumulativas mais altas de ciclofosfamida e de prednisona e também apresentaram maior razão dose-tempo de azatioprina. Em análise multivariada, incluindo pacientes e controles, a história de 3 ou mais parceiros sexuais ao longo da vida e o diagnóstico de LES, determinaram aumento de 2 e 6 vezes respectivamente, na prevalência da infecção por HPV. Essas mesmas variáveis também determinaram um aumento de 3 e 6 vezes na freqüência de displasias cervicais respectivamente. Os resultados obtidos neste estudo demonstram que pacientes com LES, têm maior freqüência de infecção por HPV e de displasias cervicais principalmente das lesões pré-malignas, e que esse aumento de prevalência é ainda mais significativo para as que receberam imunossupresssores por períodos prolongados. / Systemic lupus erythematosus (SLE) that is an autoimmune disease with higher prevalence among women, causes potencially severe lesions in different organs. SLE treatment commonly includes the use of steroids and cytostatic agents, being the latter partially responsable for an increased frequency of infection and neoplasia mostly hematologycal and virus-associated cancer. Studies that included women with SLE, have detected higher frequencies of cervical dysplasia, mainly the pre-malignant ones, however few were able to analyse its association with immunosuppressors. Taking into consideration that HPV infection is the most frequent sexually transmitted disease and that this virus is the etiologycal agent of cervical cancer, the second most prevalent neoplasia among women, this study was designed to detect the frequency of HPV infection and cervical dysplasia in SLE patients and to establish its association with classical risk factors and the use of immunosuppressors. We selected 177 SLE patients and 244 women without SLE and who did not present any complain or known gynecological disease who attended to the HUPE-UERJ or Policlínica Piquet Carneiro-UERJ gynecology clinics (control group). All women were previously explained the study and signed an informed consent approved by the HUPE-UERJ Ethical Committee. HPV detection and genotyping were performed by proteinase chain reaction and cytopatology by Papanicolaou technique with analysis by two pathologists. Patients with SLE presented higher frequency of HPV infection and cervical dysplasia than control group (Chi square, P<0.05), despite they presented less frequently the classical HPV associated risk factors (p<0.05). Long-term use of immunosuppressors determined among LSE patients, a three-fold increase on HPV prevalence (28.2%). Also among SLE patients, those who presented HPV, have received higher cumulative doses of cyclophosphamide and prednisone and also had a higher dose-time ratio of azathioprine. Multivariate analysis that included all patients and controls, detected that history of 3 or more life-time sexual partners and the diagnosis of SLE, determined an increase of 2 and 6 times respectively on HPV prevalence. These same variables also determined an increase of 3 and 6 times respectively, on the prevalence of cervical dysplasya. The findings of the present study confirm that SLE patients have higher frequency of HPV infection and cervical dysplasia, mostly the pre-malignant and that it is even more significant for those who received immunosuppressors for long periods.

JENÍKOVÁ, Aneta January 2017 (has links)
This thesis is titled: Sister in care of a child with congenital dysplasia of the hip joint. The aim of this work is to map the care of a child with congenital dysplasia of the hip joint, including the historical view, and the role of the nurse in this subject. The thesis presents the disease from the very beginning in the mother's body, after its development, diagnosis to the development of the treatment to the present time. The aim of the thesis is to introduce the reader with the history of this defect of the locomotory system and provide a summary of available information. Emphasis is placed on advancing conservative treatment and on nursing care in a hospital for a child with congenital dysplasia. The work is enriched with information from a doctor - ortopedic, nursing nurse and orthopedic nurses. In terms of methodology, methods of explanation, synthesis and induction are used. These methods consist of a summary and a combination of collected primary information and are focused on the logical reconstruction of the explanation and understanding of the topic. The sources are drawn from the Medvik, PuBMed, and Ebsco web sites, which provide me with an overview of sources written in czech, english and german language. It is also drawn from the findings of the Medical Museum in Prague, where I got to the primary source from 1895. This thesis will find use for those interested in this issue, for healthcare professionals in the context of expanding knowledge and for parents born to a child with hip dysplasia.

Les dysplasies tubo-ovariennes : contribution à une meilleure compréhension de la carcinogenèse ovarienne / Ovarian and tubal dysplasia : an early event in the pathogenesis of epithelial ovarian cancer

Chêne, Gautier 14 June 2011 (has links)
Introduction : l’analyse histopathologique des pièces d’annexectomie prophylactique(pBSO) pour risque génétique (mutations BRCA) a pu révéler des anomalies cytologiques etarchitecturales interprétées comme potentiellement pré-cancéreuses et dénommées « dysplasieovarienne et tubaire ». Nous proposons d’étudier les aspects morphologiques,immunohistochimiques et moléculaires des dysplasies tubo-ovariennes.Matériels & Méthodes : l’analyse morphologique a été réalisée dans un premier grouped’annexectomies après stimulation de l’ovulation (protocole de Fécondation in vitro).L’évaluation morphologique et immunohistochimique (expression de Ki67, p53, Bcl2, PAX2et ALDH1) a par la suite concerné 111pBSO, 42 annexectomies exposées au Tamoxifène et116 témoins non cancéreux et spontanément fertiles (nBSO). Les analyses ont été réaliséespar deux pathologistes en aveugle. Les cellules épithéliales d’intérêt ovariennes et tubairesprovenant du groupe pBSO ont été microdisséquées par laser ; l’ADN extrait a été étudié parhybridation génomique comparative (CGH array). La longueur des télomères a été évaluéepar PCR quantitative en temps réel.Résultats : les scores moyens de dysplasie ovarienne et tubaire étaient significativement plusélevés dans les groupes stimulation de l’ovulation et génétique par rapport aux témoins. Seulle score de dysplasie tubaire était supérieur aux témoins pour le groupe Tamoxifène. Onretrouvait une surexpression de ALDH1 dans les groupes pBSO et tBSO alors que Ki67, p53,bcl2 et PAX2 étaient faiblement exprimés dans les groupes pBSO et tBSO. D’ailleurs,l’expression d’ALDH1 était faible dans l’épithélium non dysplasique, forte dans la dysplasieet constamment faible dans les carcinomes occultes. De subtiles altérations génomiques et desraccourcissements télomériques ont été mis en évidence au niveau des dysplasies génétiques.Conclusions : les scores élevés de dysplasie, la forte expression d’ALDH1 et les altérationsmoléculaires provenant du groupe à risque génétique pourraient supporter le conceptd’instabilité génétique. La dysplasie tubo-ovarienne pourrait être une étape importante etprécoce de la carcinogenèse ovarienne. Nos résultats suggèrent également qu’un certainnombre de cancers de l’ovaire pourrait avoir pour origine la trompe de Fallope. Le marqueurde cellules souches ALDH1 pourrait constituer une cible dans la prévention et le diagnosticprécoce des cancers de l’ovaire. / Background: Histopathological examination of material from prophylactic salpingooophorectomies(pBSO) performed in patients at genetic risk has revealed frequentabnormalities interpreted as possible pre-cancerous “ovarian and tubal dysplasia” lesions. Wesought to study the morphologic, immunohistochemical and molecular features in ovarian andtubal dysplasiaMaterials and methods : Morphologic analysis was evaluated in 37 oophorectomies afterovulation induction (iBSO). Morphologic features and immunohistochemical expressionpatterns of Ki-67, p53, Bcl2, PAX2 and ALDH1 (an enzyme significantly associated withearly-stage ovarian cancer) were evaluated in 111 pBSO, 42 salpingo-oophorectomiesexposed with Tamosifen (tBSO) and 116 normal salpingo-oophorectomies (nBSO).Representative slides from formalin-fixed, paraffin-embedded tissue blocks were read blindlyby two gynaecological pathologists. Tubal and ovarian epitheliums from normal anddysplastic tissues (from pBSO) were laser microdissected and studied by comparativegenomic hybridization (array CGH). Telomere length was performed using quantitative realtimePCR.Results: Mean ovarian and tubal dysplasia score were significantly higher in the ovulationinduction group and in the genetic risk group than in controls. Only tubal dysplasia score wassignificantly higher in the Tamoxifen group. Increased ALDH1 expression was observed inpBSO and tBSO compared with nBSO whereas expression patterns of Ki67, p53, bcl2 andPAX2 were low at moderate in pBSO and tBSO group. Interestingly, ALDH1 expression waslow in non dysplastic epithelium, high in dysplasia and constantly low in the carcinoma foundincidentally on pBSO. Subtle genomic alterations were found in the dysplastic ovarian andtubal epitheliums. Shortened telomeres were found in dysplastic tissues from pBSO.Conclusion: The increased dysplasia scores, the strong ALDH1 expression and the geneticalterations in ovaries and tubes from BRCA 1/2 carriers could support the genetic instabilityof dysplasia and might be consistent with progression towards neoplastic transformation andcould justify the use of the term “dysplasia”. Ovarian and tubal dysplasia may be a premalignant,non-invasive histopathological abnormalitie that could be an important step in11early ovarian neoplasia. Our results suggest that a greater percentage of ovarian cancers thanoriginally thought may actually have a fallopian origin with metastasis to the ovary. The stemcell marker ALDH1 activation in pBSO could be considered as a target for early diagnosisand prevention of ovarian cancers.

Estudo clínico e molecular de pacientes com displasia septo-ótica ou deficiência hormonal hipofisária (gene HESX1 e PROP1) /

Cruz, Juliana de Barros. January 2008 (has links)
Resumo: A hipófise anterior compõe-se de cinco tipos celulares que são definidos pelos hormônios que secretam. A diferenciação desses tipos celulares resulta de uma cascata temporalmente regulada de fatores transcricionais expressos no tecido hipofisário. Mutações de um desses fatores podem resultar tanto em defeitos estruturais da glândula como em deficiências hormonais, que podem ser isoladas (Déficit de hormônio do crescimento - DGH) ou combinadas (DHHC), dependendo do papel do fator transcricional mutado. A Displasia Septo - óptica (DSO) caracteriza-se pela presença de hipoplasia hipofisária, hipoplasia de nervo óptico e/ou má formações de estruturas da linha média. Foram avaliados 11 pacientes com quadro clinico de SOD, DGH e DHHC e realizado o sequenciamento genético do gene HESX1 desses indivíduos. Nos casos de DHHC foi feita uma análise adicional do gene PROP1. A mutação missense em estado de heterozigose A1772G levando a substituição N125S foi identificada em um paciente portador de DSO, no gene HESX1. Essa troca já foi previamente relatada como um polimorfismo na população Afro-Caribenha. Encontramos três pacientes portadores da variante alélica A9A e N20S no exon 1 do gene PROP1, já descritos previamente na literatura como polimorfismos. / Abstract: The anterior pituitary is made of five types of cell defined according to the hormones they secrete. Differentiation among such cell types derives from a cascade of temporally regulated transcriptional factors expressed in the pituitary tissue. Mutation in one of these factors may result in both structural gland defects and hormonal deficiencies, which may be either isolated (DGH - Growth Hormone Deficiency) or combined, depending on the role of the mutated transcriptional factor. Septo-optic dysplasia (SOD) is characterized by pituitary hypoplasia, optic nerve hypoplasia and/or malformation of medium line structures. Eleven patients with a clinical state of SOD, DGH and CPHD were assessed, and genetically sequenced for the HESX1 gene. For CPHD cases, an additional analysis for the PROP1 gene was also conducted. One SOD patient was found to have a missense mutation in A1772G heterozygosis state, leading to the N125S replacement, in HESX1 gene. Such replacement has already been reported as a polymorphism in the Afro-Caribbean population. We found three patients with the alelic variation A9S and N20A in exon 1 of PROP1 gene, previously described as polymorphisms. / Orientador: Célia Regina Nogueira / Coorientador: Denise Perone / Mestre

Genetická a hormonální regulace dětského růstu / Genetic and Hormonal Regulation of Children's Growth

Vosáhlo, Jan January 2014 (has links)
Genetic and Hormonal Regulation of Children's Growth MUDr. Jan Vosáhlo Abstract Growth in childhood is a complex process of changing the body, which can be disrupted by various illnesses including endocrine disorders, particularly growth hormone deficiency. Tumors or other processes affecting hypothalamic-pituitary area can be a postnatal cause of GHD; prenatal causes include 1) developmental disorders of the pituitary as part of complex syndromes, 2) developmental disorders of the pituitary due to defects in regulatory genes and 3) defects in genes involved in the synthesis and secretion of GH. The first topic of the thesis was septo-optic dysplasia - a complex syndrome involving optic nerve hypoplasia, structural brain abnormalities and pituitary dysfunctions. We extensively described phenotype in 11 Czech patients; we observed both complete SOD and incomplete forms variously combining two of the three main components of the syndrome. The cohort then became a part of an international study of 68 patients, in which we studied the phenotype in dependence on the brain morphology. We found correlation between the severity of clinical symptoms and the degree of septum pellucidum abnormities and also a correlation between hippocampus and falx abnormities and neurological symptoms. As the second topic we studied...

Etude des dysmorphoses et de la croissance de la mandibule chez un modèle murin de la dysplasie ectodermique hypohidrotique / Study of the dysmorphologies and the growth of the mandible in a hypohidrotic ectodermal dysplasia murine model

Bornert, Fabien 19 March 2013 (has links)
La dysplasie ectodermique hypohidrotique liée à l’X (DEX) est consécutive à la mutation du gène Eda. Ce projet de recherche avait pour but d’étudier les dysmorphoses cranio-faciales chez le mutant murin Tabby représentant l’équivalent phénotypique de la DEX. La forme des mandibules en vue latérale a été étudiée à partir d’approches quantitatives associant μ-CT, traitement d’images, analyses de Fourier elliptique et analyses métriques. Une première étude ex vivo menée sur 39 spécimens Tabby et 35 souris wild-type adultes a permis de mettre en évidence un hypo-développement mandibulaire chez Tabby. Deuxièmement, une étude longitudinale in vivo de la croissance mandibulaire mise en place sur une cohorte de 23 individus (12 WT et 11 Tabby) a montré que les individus Tabby présentaient cet hypodéveloppement dès le 1er mois et qu’il se maintenait à la fin de la première année de vie. Les défauts du gène Eda affectent ainsi le développement de la mandibule en plus des dérivés ectodermiques. / The X-linked hypohidrotic ectodermal dysplasia (XLHED) is the result of Eda gene defect. This research project studied the cranio-facial dysmorphoses in Tabby murin mutant which having a similar phenotype to the XLHED. A association of mutiple quantitive approachs (μ-CT, images processing, elliptical Fourier analyse and metric analyses) permitted to study the mandible’s shape in a lateral view. A first ex vivo study led on 39 specimens Tabby and 35 WT mice allowed to highlight a mandibular hypodevelopment in Tabby. Secondly, a longitudinal in vivo study of mandibular growth, based on 23 specimen (12WT and 11 Tabby), showed that Tabby presented this hypodevelopment from the 1st month and that it remained at the end of the first year of life. The Eda gene affects the development of mandible and ectodermal structures.
