Saúde bucal e cuidado odontológico: representações sociais de mães usuárias de um serviço público de saúde

Objetivo: identificar as representações sociais de mães de crianças da faixa etária de zero a cinco anos de idade do Núcleo de Saúde da Família IV, em Ribeirão Preto-SP, procurando saber o que pensam sobre saúde bucal e tratamento odontológico. Método: trata-se de pesquisa qualitativa, sendo utilizada a entrevista semi-estruturada para a coleta dos dados e a análise de conteúdo. Resultados: constatou-se grande dificuldade das mães em se expressar a respeito do que é, para elas, saúde. Para essas mães a saúde bucal está relacionada com normas de higiene e dietéticas e também com a ida ao dentista, restringindo-se na preocupação com a estética e pouco com a função. Já em relação ao tratamento odontológico, a grande maioria demonstrou apresentar medo, causado pela sua experiência anterior com o tratamento. A assistência particular está associada à pontualidade e ao atendimento da maneira desejada enquanto o tratamento oferecido pelo setor público à demora e à falta de equipamentos e materiais. A humanização no atendimento e competência do profissional emergiram como dois aspectos importantes, e podem estar determinando a decisão de ir ou não ao dentista. Conclusões: A expressão saúde bucal foi associada à assistência odontológica. O atendimento pelo setor privado foi referido como o que mais se aproxima do tipo ideal de assistência odontológica

A questão social na França contemporânea: uma experiência de pesquisa

A França passou por conflitos urbanos em seus bairros populares. Incidentes com a polícia marcados pela morte de um morador, geralmente jovem ou adolescente, são seguidos por manifestações violentas: quebra-quebras, incêndios de carros e/ou estabelecimentos públicos e privados, enfrentamentos com a polícia. Nos conflitos da "banlieue" francesa podem ser percebidos elementos comuns a eventos ingleses e/ou americanos de outras décadas.OBJETIVO: consiste em identificar a percepção e as representações de moradores sobre suas condições de vida e saúde na França.MÉTODO: pesquisa qualitativa realizada em Les Aubiers, bairro popular de Bordeaux, nos anos de 2002 e 2005. A população de moradores desse bairro e é composta principalmente por imigrantes ou fanceses de origem estrangeira, provenientes de diferentes locais: África do Norte, África Sub-Sahariana, Turquia, Portugal , Ilha de Reunião. Os indicadores sociais e econômicos apresentam níveis significativamente mais baixos do que os de outros bairros de Bordeaux, acompanhando as tendências encontradas nas outras "banlieues". Entre esses indicadores, a taxa de desemprego, principalmente entre jovens, é alarmante (40 por cento).RESULTADOS E DISCUSSÃO: as políticas sociais deveriam ser mais voltadas para os indivíduos do que para o território, pois este só poderá ser transformado pelos primeiros e não o contrário. Um bairro e uma população estigmatizados, estão contemplados por uma ampla política social. Ainda que passível de crítica, não se pode ignorar a existência de esforços sistematicos de integração, nem a existência de políticas sociais. Se elas são inadequadas, trata-se de ampliar o espaço de discusão para sua reforma. Trata-se de saber qual a disposição das sociedades contemporâneas, como um todo, para lutar contra as inequidades e segregações

Human leukocyte antigen-G expression after kidney transplantation is associated with a reduced incidence of rejection

HLA-G is a non-classic Human Leukocyte Antigen (HLA-G) Class I of low polymorphism and restricted tissue distribution that displays tolerogenic functions. In heart transplantation and in combined liver/renal allograft transplantation, the expression of HLA-G has been associated with a lower incidence of acute graft rejection episodes and absence of chronic dysfunction. Since the expression of HLA-G in renal biopsies has been investigated only in few patients who received a combined kidney and liver transplant, in this study we performed a cross-sectional study, systematically comparing the expression of HLA-G in post-transplanted renal grafts, stratifying patients according to the presence or absence of rejection. Patients and Methods: Seventy-three renal specimens (10 with acute rejection and 13 with chronic allograft nephropathy, and 50 with no signs of rejection) were immunohistochemically evaluated for HLA-G expression. Results: In the group as a whole, HLA-G molecules were detected in 40 cases (54.8%). Among specimens that presented HLA-G expression, 2 out of 40 (5%) exhibited acute rejection, 2 (5%) exhibited chronic allograft nephropathy, and the remaining 36 (90%) exhibited no signs of rejection. The comparison between patients with rejection and those without rejection showed that the expression of HLA-G was significantly increased in specimens exhibiting no signs of rejection (p<0.0001). Considering only patients with acute rejection, 8 out of 10 patients showed no HLA-G expression in their kidney biopsies when compared to patients exhibiting no signs of rejection and absence of HLA-G was observed in 14 out of 50 (p=0.0032). Similarly, considering only patients with chronic allograft nephropathy, absence of HLA-G expression was observed in I I out of 13 specimens, whereas in patients without rejection absence of HLA-G was observed in 14 out of 50 (p=0.003). Therapy with tacrolimus was significantly associated with the expression of HLA-G and a better graft prognosis. Conclusions: Our results suggest that HLA-G expression in the kidney allograft and the use of tacrolimus are associated with a lower frequency of acute renal rejection and chronic allograft nephropathy.

Intravenous glutamine decreases lung and distal organ injury in an experimental model of abdominal sepsis

Introduction The protective effect of glutamine, as a pharmacological agent against lung injury, has been reported in experimental sepsis; however, its efficacy at improving oxygenation and lung mechanics, attenuating diaphragm and distal organ injury has to be better elucidated. In the present study, we tested the hypothesis that a single early intravenous dose of glutamine was associated not only with the improvement of lung morpho-function, but also the reduction of the inflammatory process and epithelial cell apoptosis in kidney, liver, and intestine villi. Methods Seventy-two Wistar rats were randomly assigned into four groups. Sepsis was induced by cecal ligation and puncture surgery (CLP), while a sham operated group was used as control (C). One hour after surgery, C and CLP groups were further randomized into subgroups receiving intravenous saline (1 ml, SAL) or glutamine (0.75 g/kg, Gln). At 48 hours, animals were anesthetized, and the following parameters were measured: arterial oxygenation, pulmonary mechanics, and diaphragm, lung, kidney, liver, and small intestine villi histology. At 18 and 48 hours, Cytokine-Induced Neutrophil Chemoattractant (CINC)-1, interleukin (IL)-6 and 10 were quantified in bronchoalveolar and peritoneal lavage fluids (BALF and PLF, respectively). Results CLP induced: a) deterioration of lung mechanics and gas exchange; b) ultrastructural changes of lung parenchyma and diaphragm; and c) lung and distal organ epithelial cell apoptosis. Glutamine improved survival rate, oxygenation and lung mechanics, minimized pulmonary and diaphragmatic changes, attenuating lung and distal organ epithelial cell apoptosis. Glutamine increased IL-10 in peritoneal lavage fluid at 18 hours and bronchoalveolar lavage fluid at 48 hours, but decreased CINC-1 and IL-6 in BALF and PLF only at 18 hours. Conclusions In an experimental model of abdominal sepsis, a single intravenous dose of glutamine administered after sepsis induction may modulate the inflammatory process reducing not only the risk of lung injury, but also distal organ impairment. These results suggest that intravenous glutamine may be a potentially beneficial therapy for abdominal sepsis.

Arterial and interstitial remodelling processes in non-specific interstitial pneumonia: systemic sclerosis versus idiopathic

Aims: To compare septal and vascular matrix remodelling, vascular occlusion, Pulmonary function tests and survival between two groups: one with idiopathic non-specific interstitial pneumonia (NSIP) and one with NSIP associated with systemic sclerosis (SSc). Methods and results: Pulmonary biopsy specimens were examined from 40 patients, 22 with NSIP and 18 with NSIP associated with SSc. The content of septal collagen and elastic fibres, as well as the elastic fibres in the vascular interstitium, were higher in the SSc group (P = 0.01, P = 0.001 and P < 0.0001, respectively). Among pulmonary function tests. the diffusing capacity for carbon monoxide/alveolar volume was affected to a greater extent in the SSc group (59%) of the predicted value in SSc and 97% in the idiopathic group). There were no differences in collagen content of the vascular interstitium, arterial occlusion, or survival between the two groups. Conclusions: Although the fibrotic process is more intense in the SSc group. it, does not affect the prognosis of these patients. Because the elastotic process is higher in the SSc group, this might suggest that autoimmune inflammatory mechanisms affecting the elastic fibre system play a greater role in the pathogenesis and pulmonary remodelling process of SSc NSIP than in idiopathic NSIP.

HLA polymorphisms as incidence factor in the progression to end-stage renal disease in Brazilian patients awaiting kidney transplant

Chronic renal failure (CRF) leads in the majority of instances to end-stage renal disease (ESRD) requiring renal replacement therapy. Age, gender, genetics, race, hypertension, and smoking among others are factors associated with ESRD. Our interest was to evaluate the possible associations of class I and II HLA antigens with ESRD renal disease independent of other factors, among patients with CRF, having various diagnoses in the Brazilian population of the Sao Paulo state. So 21 HLA-A, 31 HLA-B, and 13 HLA-DR were detected in 105 patients who were compared with 160 healthy controls of both sexes who were not related to the patients evaluated until 2005. We calculated allelic frequencies, haplotypes frequencies, etiological fractions (EF), preventive fractions, and relative risks (RR). We compared demographic data of patients and controls. The antigens positively associated with ESRD were: HLA-A78 (RR = 30.31 and EF = 0.96) and HLA-DR11 (RR = 18.87 and EF = 0.65). The antigens HLAB14 (RR = 29.90 and EF = 0.75) was present at a significantly lower frequency among patients compared with controls. In contrast, no haplotype frequency showed statically significant associations. Further molecular studies may clarify types and subtypes of alleles involved with ESRD progression.

MRI findings of prostate stromal tumour of uncertain malignant potential: a case report

Prostatic stromal tumours are rare neoplasias that include benign, malignant and borderline lesions. Stromal tumour of uncertain malignant potential (STUMP) has been recently described and only a few reports exist in the literature. As a rare and distinct neoplasia, to date, there is no description of MRI findings of prostate STUMP. In this article, we describe the clinical and MRI features with histopathological correlation of a patient with prostate STUMP.

Interieukin-17 and Kidney Allograft Outcome

Acute rejection episodes (ARE) are important complications that involve the interplay between mechanisms that maintain graft tolerance and promote rejection. The proinflammatory cytokine interieukin-17 (IL-17) has been implicated in many conditions in humans and mice. In kidney transplant patients, the evaluation IL-17 levels has been performed in only a few patients. We performed a cross-sectional study correlating quantitative IL-17 levels and clinical outcomes. Patients and methods. We studied 19 specimens from biopsies performed in patients (n = 19) who received isolated kidney grafts. ARE signs were present in 9 (47%) patients who provide specimens; whereas, 10 (53%) others showed no signs of rejection. Eighteen healthy control sample IL-17 underwent measurement, all of which were performed by an enzyme-linked immunosorbent assay method. We assessed other factors, such as the recipients demographic data, cold ischemia time, HLA mismatches, time elapsed from transplantation to the biopsy, posttransplantation status, antibody panel, donor type, and immunosuppressive treatment. Results. IL-17 levels were clearly increased among samples derived from patients with ongoing rejection (125.7 +/- 27.06 pg/mL) in contrast, to the nonrejection group, (30 +/- 13.32 pg/mL) (P < .05). Healthy controls showed no detectable IL-17 levels. Conclusions. These findings suggested that IL-17 was important in the pathophysiology of acute kidney rejection.

Interferon-gamma+874 Polymorphism in the First Intron of the Human Interferon-gamma Gene and Kidney Allograft Outcome

Background. Despite advances in immunosuppressive therapy in the past decade, allograft rejection remains an important cause of kidney graft failure. Cytokines play a major role in the inflammatory and immune responses that mediate allograft outcomes. Several studies have shown that the production of cytokines varies among individuals. These variations are determined by genetic polymorphisms, most commonly within the regulatory region of cytokine genes. The aim of the present study was to assess the effect of allelic variation on acute rejection episodes (ARE) or chronic allograft nephropathy (CAN) after kidney transplantation. Methods. To determine a possible correlation between the interferon (INF)-gamma +874 polymorphism and kidney allograft outcome, we isolated genomic DNA from 74 patients who underwent isolated kidney allografts and were classified into 2 groups-a rejection and a nonrejection group-for comparison with a control group of 163 healthy subjects. Results. We genotyped INF-gamma +874 polymorphisms in all groups. The transplant group showed a significantly increased homozygous genotype T/T (P = .0118) compared with healthy controls. Similarly, considering only patients with CAN, the homozygous genotype T/T (P = .0067) was significantly increased compared with the healthy controls. The rejection group indicated a significant increased homozygous genotype Tic compared with the control group (P = .0061). Conclusion. Homozygous genotype T/T was associated with increased levels of INF-gamma and greater numbers among the rejection and CAN cohorts.

Glucocorticoid resistance in dialysis patients may impair the kidney allograft outcome

This study examines in vitro steroid sensitivity in chronic renal failure ( CRF) patients and its influence on the allograft outcome. We determined the inhibitory effect of dexamethasone ( DEX) on concanavalin A ( Con-A)-stimulated peripheral blood mononuclear cell ( PBMC) proliferation, and glucocorticoid receptor` ( GR) number of binding sites ( B-max) and affinity ( K-d) in 28 CRF patients and 40 normal healthy controls. Based on K-d values > 95th percentile from controls, patients were divided into two groups: glucocorticoid resistant ( n = 11) and glucocorticoid sensitive ( n = 17). Patients were followed during 18 months post-transplantation observing acute rejection episodes ( ARE), chronic allograft nephropathy ( CAN), allograft failure and death. The DEX concentration that caused 50% inhibition of Con-A-stimulated PBMC proliferation ( IC50) was higher in CRF than in healthy controls ( 2.2 x 10(-5) +/- 1.0 x 10(-5) versus 8.3 x 10(-6) +/- 4.2 x 10(-6) mol/ L, P = 0.02). Values of Kd ( 12.4 +/- 1.8 versus 7.2 +/- 0.9 nM) and Bmax ( 7.7 +/- 1.1 versus 4.1 +/- 0.3 fmol/ mg protein) were higher in CRF patients ( P = 0.02 and P = 0.001, respectively). There were higher incidences of ARE ( P = 0.02) and CAN ( P = 0.002) in the glucocorticoid-resistant group. Univariate and multivariate logistic regression showed that Kd was an independent predictor of ARE ( OR 8.8, P= 0.03) aswell as of CAN ( OR 16.5, P= 0.01). In conclusion, we observed glucocorticoid resistance in a subgroup of CRF patients undergoing dialysis, which led to a higher morbidity due to ARE and CAN in an 18-month follow-up period.

Frequency of insertion/deletion polymorphism in exon 8 of HLA-G and kidney allograft outcome

Human leukocyte antigen-G (HLA-G) is a non-classical major histocompatibility complex (MHC) class Ib molecule predominantly expressed in cytotrophoblasts, where it acts as a specific immunosuppressor. Literature data have shown that grafts in some settings, such as cardiac and liver/kidney-associated transplantations, express HLA-G and this expression is associated with less severe rejection and also reduces the incidence of rejection. Fourteen-base pair deletion/insertion polymorphism has been reported in exon 8 of the 3`-untranslated region of HLA-G. This polymorphism within exon 8 of the HLA-G gene might influence transcription activity, which in turn may influence the stability of HLA-G transcripts. This influences the stability of the HLA-G protein and therefore is of potential functional relevance. In order to determine a possible correlation between the 14-bp insertion/deletion polymorphism and kidney allograft outcome, we isolated genomic DNA from 83 patients who had received isolated kidney allografts, and we classified the 83 specimens into two groups, grafts presenting Banff features of rejection group and a non-rejection group, and compared them with a control group of 97 healthy subjects. The 14-bp polymorphism at exon 8 was genotyped in all groups. There was no significant difference in allelic frequencies of 14-bp insertion/deletion polymorphism between normal controls and kidney transplant patients. In the RG, the homozygous genotype +14/+14 bp (P = 0.0238) was significantly increased in the group with acute rejection compared with the healthy control group. Analysis of other HLA-G polymorphisms and functional studies on immune regulation are essential to elucidate the role of HLA-G in kidney allografts.

Texto para discuss??o 5: reforma administrativa e direito adquirido ao regime da fun????o p??blica

O direito adquirido tem sido argumento freq??entemente invocado pelos opositores da reforma constitucional do aparelho administrativo do Estado. Nesse debate, entretanto, este argumento ?? completamente destitu??do de validade t??cnica. Dizer que a reforma constitucional n??o pode alterar o regime jur??dico dos servidores p??blicos (o estatuto jur??dico da estabilidade, disponibilidade, remunera????o etc.) ?? incorrer em completo equ??voco. As raz??es dessa incompreens??o decorrem do desconhecimento de no m??nimo dois t??picos relevantes encartados no tema, a saber: a) a natureza do regime jur??dico que vincula o servidor p??blico civil ?? administra????o; e b) a distin????o entre efic??cia imediata e efic??cia retroativa das normas constitucionais
