Síntese de zeólitas e argilas ácidas pilarizadas a partir de matérias primas naturais

Structural changes in waste for zeolites synthesis are subject of many studies carried out in the synthesis of molecular sieves. These materials are named molecular sieves because they have well defined pore sizes and they have the capacity of select molecules by its size. In this work, it was studied the synthesis processes of two types of molecular sieves: pillared acid clays using as starting material one natural montmorillonite clay and the synthesis of zeolites from a silico-aluminous residue. This residue is a byproduct of the extraction of lithium -spodumene. The preparation of pillared acid clays was performed in two steps: 1° acid treatment of clay samples (time and temperature studies) and 2°pilarization of them with Al13 (Keggin ion). The temperature and acid concentration affect the removal of cations in the structure and porosity of the material obtained. The analysis of X-ray diffraction (XRD) and infrared spectroscopy (IR), showed that increasing the severity of the acid treatment compromises the structural material. Also the pore size distribution is approximately uniform. Despite presenting a structural disorganization, the samples were pillared. As evidenced by XRD increasing the basal spacing, specific area and uniform porosity by adsorption of N2. Regarding the microporous molecular sieves were synthesized zeolites A and NaP1 from a silico-aluminous residue, a byproduct of extracting lithium. The temperature and time of agitation during the synthesis were the most important factors for obtaining zeolite A. The aging of the gel and the highest crystallization time promoted the formation of zeolite NaP1 using a Si / Al ratio = 3.2

Hiperidrose compensatória após simpatectomia toracoscópica: características, incidência e influência na satisfação do paciente

Hyperhidrosis is an idiopathic condition characterized by excessive sweating. Symptoms generally begin in childhood or early adolescence, and rarely improve with age. The excessive localized sweating generally occurs either spontaneously, or in association with stressful or emotionally charged situations. This prospective study aimed to investigate predictive factors for compensatory hyperhidrosis after thoracoscopic sympathicotomy. From 2000 to 2002, 80 patients (53 female and 27 male) underwent hyperhidrosis surgery. The patients, ranging from 12 to 56 years old, were studied and followed-up for 42.51 ±5.98 months. A satisfaction grading using a visual analogue scale -VAS (0 = not at all satisfied, and 10 = fully satisfied) was used. The surgical procedure was performed bilaterally on the second ganglion (T2) for facial hyperhidrosis, on the third and fourth ganglia (T3 and T4) for axillary hyperhidrosis, and on the third ganglion (T3) for palmar hyperhidrosis. The results showed that, 68 patients (85%) presented with compensatory sweating (CS), which was classified as mild (33.8%), moderate (33.8%) and severe (32.4%). Considering the final surgical results, 70 patients (87.5%) were satisfied with the outcome of the operation, while 10 patients (12.5%) were dissatisfied. Degrees of satisfaction varied according to sex, age, BMI and extent of denervation. Moreover, the compensatory hyperhidrosis was more severe in abdomen and back than in legs. In conclusion, although CS is a frequent adverse effect of sympathicotomy, the degree of patient satisfaction was high. Some factors were related to the occurrence and severity of CS and the most adequate patients to be submitted to this operation are young adult women whose BMI is less than 24.9

Evuloção cognitiva e funcional de pacientes pós-acidente vascular cerebral - AVC

PURPOSE: Stroke is a high-incidence cerebrovascular disease with elevated morbidity that results in impairments such as functional disabilities. This study aimed to investigate the functional evolution of individuals in the first six months post-stroke. METHOD: Longitudinal study with 42 stroke patients. The functional independence measure (FIM) and The National Institutes of Health Stroke Scale (NIHSS) were used by multidisciplinary staff 3 times in each participant; the first application was at admission to rehabilitation and the others three and six months later. RESULTS: Sample predominantly female (57%), married (52%), mean age 65.26 ±10.72 years, elementary schooling level (43%), ischemic stroke (91%), and right cerebral hemisphere (74%). Motor FIM scores and NIHSS scale showed improvement in the 3 evaluations, with significant p-value (<0.001). There was a strong relation between motor FIM evolution and NIHSS evolution (r = - 0.69 p-value< 0.001). CONCLUSIONS: It was observed that functional evolution at 6 months post-stroke was significant and the smaller the evolution of clinical impairment in these patients, the larger the evolution of their functional independence. The study is important because it allows a more appropriate therapeutic planning according with functional evolution in stroke rehabilitation

Avaliação clínica e microbiológica das condições de saúde oral dos receptores de transplante renal do Hospital Universitário Onofre Lopes, Natal RN

Introduction: The chronic immunosuppression promotes the development of changes in the oral cavity of the kidney transplant recipients (KTR), however with the exception of gingival overgrowth, little is known regarding the prevalence of oral lesions in this population. Objective: To evaluate the prevalence of clinical and microbiological conditions of the oral cavity of the recipients of kidney transplantation and the associated factors. Methods: This was a cross-sectional study which examined 96 clinical KTR and experimental where collected saliva stimulated them to identify Candida sp. Data collection consisted of evaluation stomatologic, socio-demographic, clinical aspects of transplantation, condition of oral hygiene and dental caries, yonder to questions about knowledge of oral alteration after transplantation. Results: Of the total, 66.7% of KTR had some type of oral manifestation. The most common was saburral tongue, followed by gingival overgrowth, with both oral manifestations related to gender and concomitant use of cyclosporine and nifedipine (p <0.05). Tacrolimus showed a protective effect for gingival overgrowth (OR = 0.13). The oral hygiene was associated with saburral tongue(p = 0.03) and severity of gingival overgrowth (p = 0.0001). Oral candidiasis was diagnosed in 17.7% of patients and Candida albicans was isolated most frequently in the saliva of RTR with a colonization of 58.3%. The average DMF-T increased with age. The method of oral hygiene was most used brush and toothpaste to 61.5%. Changes in the oral cavity was seen in 54.2% of KTR, citing as the main growth and gingival ulcers. Instructions for oral hygiene after transplantation were neglected for 61.5% of RTR. Dry mouth and halitosis were reported in 30.2% and 36.5% respectively. Conclusions: More the half of the KTR had at least one injury of the mouth, the immunosuppressive drugs and oral hygiene are associated with these alterations. Prospective cohort studies are needed to elucidate the relationship between oral manifestations and levels of drug and risk of oral manifestations occur over time. The kidney transplant recipients showed to be aware of oral alterations occurred after transplantation and uninformed about the oral hygiene instructions. With regard to hygiene, the incidence of caries was considered high, conditions of risk were identified and improvements in primary attention should be encouraged and reflected in the monitoring of renal transplant

Avaliação do desempenho funcional de crianças com paralisia cerebral de acordo com níveis de comprometimento motor

Contextualization: Several studies have examined the mobility of this group of children, however little is known about the impact of motor function in activities of daily living, considering the seriousness of their neuromotor damage. Objective: Identify the functional differences of children with Cerebral Palsy with different levels of motor dysfunction and correlate these differences with the areas of mobility, self-care and social function in functional ability and caregiver´s assistance of these children. Methods: An l analytical cross-section search was developed, which were part 70 children / families aged from 4 to 7.5 years, in the Rehabilitation Center for Children. As tools were used the Pediatric Evaluation Disability Inventory (PEDI) and the Gross Motor Function Classification System (GMFCS). Data analysis was performed by ANOVA and Pearson's correlation tests. Results: The results show the functional variability of children CP in different severity levels of motor disfunction This variation was observed in the areas of mobility, self-care and social function. The results also showed a strong correlation between the domains mobility and self-care, mobility and social function. Conclusions: The variability shown by the children with CP, suggests the use of PEDI and GMFCS as this association appears to increase the understanding of how the gross motor functions are related to activities of daily living, describing the best commitments and their degree of impact on functional activities. This correlation demonstrates how mobility is crucial to evaluate the performance and guide the therapeutic practice, to develop the children´s potencial, and guide the caregiver in stimulation

Funcionalidade em pacientes após acidente vascular encefálico: relação com o sono e ritmo de atividade-repouso

It is known that sleep plays an important role in the process of motor learning. Recent studies have shown that the presence of sleep between training a motor task and retention test promotes a learning task so than the presence of only awake between training and testing. These findings also have been reported in stroke patients, however, there are few studies that investigate the results of this relationship on the functionality itself in this population. The objective of this study was to evaluate the relationship between functionality and sleep in patients in the chronic stage of stroke. A cross-sectional observational study was conducted. The sample was composed of 30 stroke individuals in chronic phase, between 6 and 60 months after injury and aged between 55 and 75 years. The volunteers were initially evaluated for clinical data of disease and personal history, severity of stroke, through the National Institute of Health Stroke Scale, and mental status, the Mini-Mental State Examination. Sleep assessment tools were Pittsburgh Sleep Quality Index, the Questionnaire of Horne and Ostberg, Epworth Sleepiness Scale, the Berlin questionnaire and actigraphy, which measures were: real time of sleep, waking after sleep onset, percentage of waking after sleep onset, sleep efficiency, sleep latency, sleep fragmentation index, mean activity score. Other actigraphy measures were intraday variability, stability interdiária, a 5-hour period with minimum level of activity (L5) and 10-hour period with maximum activity (M10), obtained to evaluate the activity-rest rhythm. The Functional Independence Measure (FIM) and the Berg Balance Scale (BBS) were the instruments used to evaluate the functional status of participants. The Spearman correlation coefficient and comparison tests (Student's t and Mann-Whitney) were used to analyze the relationship of sleep assessment tools and rest-activity rhythm to measures of functional assessment. The SPSS 16.0 was used for analysis, adopting a significance level of 5%. The main results observed were a negative correlation between sleepiness and balance and a negative correlation between the level of activity (M10) and sleep fragmentation. No measurement of sleep or rhythm was associated with functional independence measure. These findings suggest that there may be an association between sleepiness and xii balance in patients in the chronic stage of stroke, and that obtaining a higher level of activity may be associated with a better sleep pattern and rhythm more stable and less fragmented. Future studies should evaluate the cause-effect relationship between these parameters

Análise de polimorfismos dos genes da rota quinureniana em pacientes com meningite bacteriana.

Bacterial meningitis (BM) is still an important infectious disease causing death and disability. Invasive bacterial infections of the central nervous systems (CNS) generate some of the most powerful inflammatory responses known, which contributes to neuronal damage. The DNA microarray technology showed alterations in the kynurenine (KYN) pathway that is induced in BM and other diseases associated with inflammation, leading to brain injury. Our main aim was to search SNPs previously described in the KYN path enzymes to investigate a putative association of this SNPs with imbalanced in this pathway in patients with BM. The patients included in this study were 33 males and 24 females, with ages varying from 02 months to 68 years. SNPs were located inside of the domain conserved in KYNU, IDO, KATI and KATII. Primers were designed for analysis of SNPs already described by PIRA-PCR followed by RFLP. The analysis of KYNU+715G/A SNP found a heterozygous frequency of 0.033. We did not found the variant allele of SNP KYNU+693G/A, KATI+164T/C, KATII+650C/T and IDO+434T/G. Despite of previews studies showing the importance of KYN pathway we did not found one association of these SNPs analyzed with susceptibility or severity of MB in study population.

Doença periodontal e angina pectoris estável: um estudo caso-controle

The search which it aim was to analyze the Periodontal Disease as a risk factor for the development of the Stable Angina Pectoris. For that, 120 patients (52 blokes and 68 wenches ), ages ranging from 40 to 65 years old, and attended to the Hemodinamic´s Sector of the Natal Hospital Center, showing the historic of Angina Pectoris to accomplishment of cinecoronariografhy. Before the accomplishment of this exam, the patients were submitted to interview, to investigate the possible risk factors for the Cardiovascular diseases , and it was followed of clinical periodontal examination to evaluate the presence of Periodontal Disease. After the cinecoronariography, the patients who presented diagnosis of important arterial obstruction (above 70%) were enrolled to the case grup. However the individuals with arteries free of obstruction, or obstrution below 30%, were considered without historic of Cardiovascular disease and therefore enrolled for the control grup. The groups were paired by the variables age and gender. From the analysis of the results, a did not observed statisticment the significant association between the presence of the Periodontal Disease, probing depth, periodontal attachment level, severity and extension index of the Periodontal Disease, besides the visible plaque index (VPI) an gingival bleeding index (GBI) regarding to the existence of Stable Angina Pectoris. Nevertheless , it was identified statisticment the significant association between the sistemic arterial hypertension , seric level of total cholesterol, LDL, HDL and triglycerides, showing all of them, classic risk factors appointed by the literature. Therefore, it was conclued that Periodontal Disease did not represent association with the StableAngina Pectoris at least among the studied population

Qualidade de Vida, Saúde Geral e Ansiedade em pacientes com diferentes tipos e níveis de disfunção temporomandibular

Some studies reported in the literature that emotional factors and quality of life may be involved both in aetiology, as in the progression of Temporomandibular disorders (TMD). Proposition: The purpose of this study is to observe a possible association between different forms of anxiety, quality of life and general health of patients diagnosed as carriers of various types and levels of Temporomandibular Dysfunction. Methodology: The sample consisted of 60 patients diagnosed as carriers of TMJD origin of muscle, joint, or both, with different levels of severity (mild TMD, moderate and severe). The patients were diagnosed with TMD-RDC (Research Diagnostic Criteria) to assess the type of dysfunction (muscle or joint) and by the Protocol of Fonseca to verify the degree of dysfunction (mild, moderate or severe). To evaluate the psychosocial aspects were used three self-applied, with the purpose of obtaining information about the general health (General Health Questionnaire - GHQ), the type of anxiety (Trait Anxiety Inventory-State - STAI) and quality of life (World Health Organization Quality Of Life Short WHOQOL-brief). Results: There was a correlation between all indicators studied in several forms of TMD with varying degrees of commitment. Quality of life appeared linked to the type and the level of TMD: Muscular and Articular TMD (p = 0,037), Disk Displacement With Reduction (p = 0.01) and Mild TMD (p = 0.042). The General Health showed association with the level of TMD, with the exception of the stress factor (p = 0.78). For the analysis of the types and levels to Severe Muscular TMD had a statistically significant indicator of the quality of life (p = 0049). The anxiety only showed association with the level of TMD (p = 0,047 for anxiety-trait). Conclusion: Besides the limitations of the study, it was concluded that anxiety, quality of life and general health are important psychosocial indicators, which are linked to several forms of TMD in different levels of severity

Impacto sócio-dentário das oclusopatias e suas respectivas necessidades de tratamento na qualidade de vida de adolescentes

Nas últimas décadas, com a significativa redução da cárie dentária em crianças e adolescentes, uma maior atenção tem sido dada a outros problemas bucais como as oclusopatias. Em termos epidemiológicos no Brasil, esta tem ocupado o terceiro lugar dentre os problemas de saúde oral na população e, portanto, a inclusão destas como um problema de saúde pública se deve não apenas à sua alta prevalência, mas também ao impacto social, que interfere diretamente na qualidade de vida das pessoas. Diante do exposto é que este estudo objetiva buscar o impacto da presença e severidade das oclusopatias e suas respectivas necessidades de tratamento na qualidade de vida de adolescentes escolares de um município. Sendo assim, foram examinados 356 escolares na faixa etária de 15 -19 anos e determinadas a prevalência, severidade e necessidade de tratamento de oclusopatias através dos índices DAI, IOTN e ICON. O impacto sócio dentário das oclusopatias na qualidade de vida dos adolescentes foi analisado através do índice CS-OIDP. A fim de se verificar possíveis influências de variáveis estudadas na determinaçao do impacto na qualidade de vida das oclusopatias, estas serão coletadas através do estatus sócio-econômico, gênero, idade e tipo escola. Nos resultados parciais, relacionado a 50% da amostra, se observou uma maior prevalência do escolares de escola pública(68,1%), idade entre 15-16 anos(74,7%), gênero feminino(52,7%) e maior prevalência do SES baixo(77,5%). A análise estatística usando o teste qui-quadrado mostrou uma associação significativa do impacto da oclusopatia na qualidade de vida apenas quando avaliada com o índice ICON e o A-IOTN do examinado, comprovando uma associação da necessidade de tratamento com a presença do impacto na qualidade de vida. Com isso, busca-se comprovar e enfatizar a necessidade de se estabelecer políticas públicas que trabalhem na prevenção e interceptação dessas oclusopatias na população, melhorando, portanto, a qualidade de vida e saúde oral dos adolescentes.

Imunoexpressão de fatores reguladores da osteoclastogênese na doença periodontal em humanos e sua relação com os parâmetros clínicos

Periodontal disease is an infection initiated by oral periodontal pathogens that trigger an immune response culminating in tissue destruction. This destruction is mediated by the host by inducing the production and activation of lytic enzymes, cytokines and the stimulation of osteoclastogenesis. The aim of this study was to compare the immunohistochemical expression of factors involved in bone resorption, RANKL (Ligand Receptor Activator of Nuclear Factor kappa B), OPG (Osteoprotegerin) and TNF-α (tumor necrosis factor alpha) between the gingival healthy, gingivitis and chronic periodontitis and correlate them with clinical parameters. The sample consisted of 83 cases and 12 clinically healthy gums, 42 gingivitis and 29 periodontitis, from 74 adolescent and adult patients with a mean age of 35 years, without systemic changes and non-smokers, predominantly female and race brown. There was no statistically significant difference for the expression of anti-RANKL (p = 0.581) and RANKL / OPG ratio (p = 0.334) when comparing the three conditions, but the anti-OPG and anti-TNF-α showed statistically significant between the types of injury (p = 0.001 and p <0.001, respectively), showing greatest expression in periodontitis. In cases of periodontitis, the variable clinical attachment loss (PIC) was statistically significant and positive correlation, respectively, with immunostaining of anti-RANKL (p = 0.002, p = 0.001 and r = 0.642), anti-OPG (p = 0.018, p = 0.014 and r = 0.451), anti-TNF-α (p = 0.032, p = 0.014 and r = 0.453) and the percentage ratio of RANKL / OPG (p = 0.018, p = 0.002 and r = 0.544). The tooth mobility (MB) showed a statistically significant difference only with immunohistochemical anti-RANKL (p = 0.026), and probing depth (PD) was positively correlated with anti-RANKL (p = 0.028 and r = 0.409), both in cases of periodontitis. Only in cases of gingivitis TNF-α was positively correlated with RANKL (p = 0.012 and r = 0.384) and the RANKL / OPG ratio (p = 0.027 and r = 0.341). Given these results, we conclude that the greatest expression of TNF-α in periodontitis demonstrates a relationship with the progression and severity of periodontal disease and the correlation between all antibodies and clinical attachment loss demonstrates their involvement in periodontal bone resorption

Prevalência da disfunção temporomandibular em estudantes de odontologia por meio de diferentes índices

The epidemiology of temporomandibular disorders varies widely in the literature. The aim of this study was to determine the prevalence of TMD in dental students of the Federal University of Rio Grande do Norte assessed by different indexes. The sample consisted of 101 individuals selected by a randomized process, whose general outline was systematic sampling. For evaluation of the signs and symptoms of TMD, an anamnestic index, Fonseca s protocol, and two clinical indexes, the RDC/TMD (Research Diagnostic Criteria for Temporomandibular Disorders), or standard index, and the Helkimo s Clinical Dysfunction Index were applied. Data were analyzed using the chi-square test and kappa, besides verifying the sensitivity and specificity (5% significance). The diagnosis of TMD by different indexes showed a variation in the prevalence between 72.3% (Helkimo s Clinical index), 64.4% (Fonseca s anamnestic index) and 35.6% (RDC/TMD). There was no statistical difference between the sexes for the RDC/TMD, although this difference was found for Fonseca s and Helkimo s indexes (p<0.05). The most frequent type of TMD were joint disorders (Groups II and III), and the subtypes disc displacement with reduction (17.8%) and arthralgia (15.8%). Most individuals showed a mild TMD (45.5%) for both indexes, Fonseca and Helkimo. When comparing the types of diagnoses, RDC/TMD with Fonseca and Helkimo, low agreement was found (k=0.17 and k= 0.35, respectively). A moderate correlation between the severity of TMD was obtained (kw= 0.53) for Fonseca s protocol and Helkimo s index. High sensitivity and low specificity were seen for both diagnoses compared to standard, resulting in excessive false positives. Within the limitations of the study, it was concluded that the prevalence of TMD can vary widely, depending on the index used for its diagnosis

Qualidade de vida de pacientes com deformidade dentofacial

In the last decade, an increasing number of studies focusing on the impact of oral deformities on quality of life have been published. However, the evaluation of patients at different phases of the treatment has not been performed. Therefore, the purpose of this study was to determine the impact that dentofacial deformities have on patients` quality of life, as well as the influence exerted by social, economic, demographic and orthodontic factors, type and severity of malocclusion. A bicentric study - of the cross-sectional type of repeated panels - involving two cities - Natal and Rio de Janeiro - was carried out. A total of 227 patients participated in the study: 71 patients in the initial phase of the treatment (before any orthosurgical procedure), 115 patients in the pre-surgical (with braces) phase and 41 patients in the postoperative phase. The quality of life was measured using the Orthognatic Quality of Life Questionnnaire - OQLQ, translated and validated into Portuguese. The normative and aesthetic need for treatment was assessed with the Index of Orthodontic Treatment Need (IOTN) and the Dental Aesthetic Index (DAI); the social, economic and demographic factors, the type of service and malocclusion were also assessed. The data were analyzed through χ2/ Fisher`s exact test to seek the association between the nominal categorical variables in the three phases of treatment, Mann Whitney and Kruskal-Wallis test for gauging the existence of significant differences between two and three groups regarding each domain of OQLQ, respectively. For all tests, it was adopted a significance level of 5%. There was a statistically significant difference (p <0.001) in the general scores of OQLQ and in the domains of social aspects, facial aesthetics and oral function, when the "postoperative group" was compared to the "initial" and "orthodontic preparation" groups. Women, single, aged between 31 and 59 and living in Natal had the greatest impact on quality of life among patients in the "orthodontic preparation" group. Only the variable "income" (2 to 3 minimum wages), for the "initial" group, and gender (female) for the "postoperative" group, showed significant association with quality of life. The normative variable IOTN (DHC and AC) showed significant association with the OQLQ for the "initial" group, and the IOTN-AC-auto in the group of orthodontic preparation, being less important to women. We conclude that the ortho-surgical therapy has positive effects on quality of life after orthognathic surgery

Conhecimento sobre ergonomia no âmbito acadêmico: um estudo com alunos e professores de odontologia

OBJETIVO: As doenças osteomusculares são as afecções ocupacionais mais prevalentes em cirurgiões-dentistas. Nosso propósito: 1) investigar os conhecimentos, aplicabilidades clínicas dos princípios ergonômicos em discentes e docentes em atividades clínicas de uma universidade pública 2) pesquisar a incidência de sintomatologias dolorosas no pescoço, ombros, parte superior e inferior das costas, cotovelos, quadris, coxas, joelhos, tornozelos e pés no universo de alunos em estágios clínicos. 3) incitar discussões de normas e diretrizes ergonômicas na universidade. MÉTODOS: Esse estudo investigou o universo de alunos matriculados em disciplinas clínicas (148) e respectivos professores (30) do curso de odontologia da Universidade Federal do Rio Grande do Norte, Natal-RN a respeito dos princípios ergonômicos utilizados na rotina clínica. Paralelamente foi pesquisada a incidência de sintomatologia dolorosa nos alunos por intermédio do questionário nórdico e a partir dos resultados foi mensurado o índice de severidade dos sintomas em alunos. The Nordic Musculoskeletal Questionnaire (NMQ) é um instrumento de diagnóstico, proposto para padronizar a mensuração de relatos de sintomas osteomusculares. A análise dos dados foi através do programa SPSS-Statistical Package for the Social Sciences, versão 17.0 realizada analítica e descritivamente, com determinação das médias (x), desvio-padrão para variáveis quantitativas, freqüências simples e relativas para as variáveis categóricas, além da estatística de associação entre grupos (teste t) e a análise de associação do quiquadrado com nível de significância 5% entre as variáveis (Person). As respostas das questões abertas foram codificadas e transformadas em freqüências, descritas posteriormente. RESULTADOS: A aplicabilidade de medidas ergonômicas nas clínicas universitárias não foi evidenciada pelo universo de discentes e docentes. Quanto ao relato de sintomas osteomusculares o sexo feminino foi o mais acometido qualquer que seja o nível acadêmico cursado. As regiões anatômicas de maior grau de severidade de relatos dos sintomas foram: pescoço, parte inferior das costas, punhos, mãos e ombros, com significância etatística p<0,001. CONCLUSÃO: Em função dos achados os autores apresentam um protocolo de intervenção clínica baseado nos determinantes ergonômicos da Associação internacional de ergonomia (EAI) como medida de prevenção da saúde ocupacional dos futuros cirurgiões-dentistas ainda em processo de formação nas clínicas odontológicas das universidades.
