Efetividade da terapia fisica descongestiva na cicatrização de úlceras venosas

A venous ulcer is the most serious clinical manifestation of chronic venous failure, and the most frequent in lower limbs, accounting for 70% of all ulcers. Patients may suffer from this infirmity for several years without healing of the lesion if treatment is inadequate. The aim of this investigation was to verify the effectiveness of decongestive physical therapy in the healing of venous ulcers. This is a quasi-experimental, interventionist study, with paired, non-probabilistic sampling, composed of 50 patients divided into two groups: control and intervention, each composed of 25 patients. Both groups were identically treated for six months with daily dressings and the latter also underwent complex physical therapy consisting of a combination of the following techniques: manual lymphatic drainage, compression bandaging, lower limb elevation, myolymphokinetic exercises and skin care. The study was approved (Protocol no. 59/2007) by the Ethics Committee of the State University of Southeast Bahia. The Mann-Whitney and Chi-square tests were applied for data analysis. After statistical analysis the patients who underwent therapy showed a statistically significant difference with respect to wound contraction starting in the second month of treatment. Compared to the control, the intervention group showed a greater reduction in both pain and edema starting in the third and fourth month of therapy, respectively. To reinforce these findings, the mean percentage of tissue present at the base of the ulcer (granulation/fibrin ratio) was calculated. The intervention group showed greater granulation at the base of the ulcer compared to the control, significant from the second month of treatment on. It was observed in this study that lymphotherapy, when compared between the intervention and control groups, accelerated the healing process, and reduced pain and edema in the affected limbs. It is expected, therefore, that these results widen scientific knowledge and we suggest that this therapy be used 78 not only to reduce lymphedema, but also as a treatment option for venous ulcers, given its easy application and low cost. The data, therefore, demonstrated the importance of basic care on the part of a multiprofessional and transdisciplinary health team involved in the healing process of these infirmities, thereby contributing to better quality of life in these individuals

Estudo epidemiológico das parasitoses oculares na população de escolares da cidade de Natal-RN, Brasil

The objective of this study is to estimate the prevalence of Ocular Toxocariasis, Diffuse Unilateral Subacute Neuroretinitis (DUSN), Toxoplasma gondii infection and Ocular Toxoplasmosis in a student population in Natal-RN/Brazil and relate it to demographic, epidemiologic and socio-economic risk factors. The incidence of DUSN was observed in patients at the Federal University of Rio Grande do Norte Ophthalmology Service and the Prontoclinica de Olhos Ophthalmology clinic in Natal. In cases where a worm was found in the subretinal space, the result of treatment with photocoagulation using Green Laser (Eye Light ALCON) was evaluated in relation to final visual result. The sample was randomly selected among the schools of the four districts of Natal, according to the type of institution (public or private), its level (elementary or secondary), and study period (morning, afternoon or evening). The school population was studied from March to May, 2001. Initially, the students answered a questionnaire to evaluate demographic, epidemiologic and socio-economic risk factors. Afterwards, the following procedures were carried out: blood samples were taken for Toxoplasmosis (IgG, IgM) serology, hemogram, ophthalmological examination, consisting of clinical history, measurement of visual acuity, refraction under cycloplegia, biomicroscopy of the anterior segment and annexa, funduscopy and examination of extrinsic motility. The prevalence of Toxocariasis was 0.2% or 2 per one thousand students. The sample was insufficient to estimate the prevalence of DUSN. Seventy patients with DUSN diagnosis were examined from January, 2001 to January, 2003. A live worm was found in the subretinal space of all four patients in the acute phase, and these were treated with laser photocoagulation. After follow-up (average = 11.5 months), visual acuity improved in three eyes and remained unaltered in one eye. Worms were found in 22 of the 66 patients in the chronic phase, and these also were treated with laser photocoagulation. After a follow-up period of 13.1 months, on average, visual acuity improved in two of the patients, remained unchanged in 19 and worsened in one. The comparison of visual result before and after treatment was not statistically significant (p = 0.302). The diagnosis of DUSN in the acute phase, followed by prompt localization and destruction of the worm by photocoagulation, can improve the patient s vision. However, destruction of the worm by laser photocoagulation in eyes with DUSN in the chronic phase does not improve visual acuity. Seroprevalence for IgG was 46% (Confidence Interval CI 95%-42.9-49.2%) and for IgM it was 1.4% (CI 95% = 0.8-2.4%). The prevalence of ocular lesion was 1.15% (CI 95% = 0.6 - 2.0%). Socio-economic conditions were determinants in the prevalence of Systemic and Ocular Toxoplasmosis in the bivaried analysis and confirmed in the multivaried analysis (mother s scholarity illiterate/ OR = 2.9 and p < 0.001). The T. gondii infection prevalence, although high, was less than that found in studies performed in the South and Southeast of Brazil and that of Ocular Toxoplasmosis was completely discrepant, varying from 5 to 17 times less. Although important epidemiological variables such as owning a cat, drinking unfiltered water, and coming into contact with rivers or lakes showed an association in the preliminary analysis, they lost their influence when included in the logistic model. Future studies are scheduled to begin in March, 2004, in collaboration with other Brazilian and American universities in an attempt to discover the reason for these findings, as well as identifying the different strains of Toxoplasma gondii, and studying the sources of water utilized by the population of Natal Brazil

Freqüência e etiologia das dermatomicoses em pacientes atendidos no Hospital Giselda Trigueiro, Natal, RN

Dermatomycoses are fungal infections that attack the skin, hair and nails, in addition to the mucosal and cutaneous-mucosal zones. Objective: Observe the frequency of dermatomycoses, identify etiological agents and establish an association between the results and sex. Age, collection site, time and lesion location. Methods: Between February, 2002 and December, 2004, samples were collected from patients at Giselda Trigueiro Hospital in Natal, Brazil, by lesion scraping and hair removal, following 70% alcohol disinfection, and submitted to direct and culture examination. Results: Of the 817 lesions collected, 325 (39.8%) were fungus positive, with the hair collection site yielding the highest number of positive results (65.8%) and the scalp and hair representing the most frequent lesion sites (65.9%). Negative results occurred mainly in the lower limbs (78.6%). Of the species identified, 55.9% were yeasts, 41.6% dermatophytes and 2.5% Fusarium spp. Non-albicans Candida was the most isolated yeast (43.3%), mainly in females (61.7%) over the age of 40 years (56.4%). T. rubrum was the most isolated dermatophyte (67.9%),notably in males (59.2%) in the 0-20 age group (44.7%). With respect to collection site, 73.9% of the dermatophytes were present in the skin and 61.1% of the yeasts in the nails. When assessing the collection site, the inguinocrural regional was 22.6% positive for dermatophytes, and the nails and hands, 41.8% for yeasts. Conclusions: The results obtained verified that: most of the positive lesions were found in the hair, whereas skin and nail lesions yielded more negative results; T. rubrum was the most isolated dermatophyte and non-albicans candida the most commonly found yeast; positivity was greater in males in the 0-20 year age group at the skin site and in the inguinocrural region, while yeasts were more frequent in females in the over-40 age group at the nail sites

Alterações nas concentrações das SRAT, conteúdo de GSH e atividade da CAT em pacientes com esquistossomose aguda

Schistosomiasis is an ancient disease caused by helminth Schistosoma mansoni and is a public health problem in Brazil. The granulomatous lesion, typical of the disease, associates itself with increase in the oxidative damage through the generation of free radicals. The aim of this work was to evaluate the occurrence of changes in parameters oxidant / antioxidant that are part of the human defense system, and observe whether they would cause oxidative stress in subjects with schistosomiasis. Moreover, correlating with some biochemical and hematological parameters. Two groups were selected for study, consisting of individuals of both sexes, aged between 16 and 30 years. A control group, formed by individuals without schistosomiasis (n = 30) and a test group, formed by individuals with schistosomiasis (n = 30). The evaluation of lipid peroxidation in plasma was performed by determination of malondialdehyde and antioxidant defense by the quantification of reduced glutathione and catalase activity. For the parameters that assess oxidative stress, the results showed a decrease in the content of reduced glutathione and no change in the activity of catalase, with an increase in the value of malondialdehyde. Therefore, the data found suggest the occurrence of oxidative stress in subjects with schistosomiasis. Of the parameters that assess hepatic function, only levels of aspartate aminotransferase have been high, while there was a decrease of bilirubine. There was a significant change in the lipid profile (p <0.5), however with regard to the renal function of patients, there was a decrease in creatinine. The assessment hematological, made through hemogram and the quantification of hemoglobin, shows increase of eosinophils individuals in the group test, which can be related to the presence of the parasite. The amendments suggest the involvement of oxidative stress in the pathophysiology of this disease

Avaliação da expressão das moléculas HLA de classe I não clássicas HLA-G E HLA-E em espécimes gástricas de pacientes acometidos com a bactéria Helicobacter Pylori

The expression of human leukocyte antigen G (HLA-G) and human leukocyte antigen E (HLA-E) in physiological and pathological processes remains unknown, it is believed that these molecules play a fundamental role in the establishment and maintenance of immune tolerance by inhibiting the functions of immunocompetent cells. In literature we found no published study involving the bacterium Helicobacter pylori (H. pylori) with expression of HLA-G and HLA-E. The objective this study is investigated the expression of this protein in gastric biopsies of patients with the bacterium H. pylori. Sixty-four biopsies of the patients with diagnosis of infection by H. pylori were evaluated to expression of HLA-G and HLA-E. The samples were stratified according to the presence of carcinoma or peptic ulcers. Patients without H. pylori were used to control. To investigate the expression of this protein were used immunohistochemistry technique with monoclonal antibody anti-HLA-G and anti-HLA-E. Other criteria such as analysis of the inflammatory infiltrate (hematoxylin-eosin) and identification of H. pylori (Giemsa) were analyzed. We detected HLA-G and HLA-E molecules in the most samples containing ulcer and gastric carcinoma. In negative control group was not detected the presence of HLA-G and HLA-E. The presence of H. pylori seems modulate the expression of HLA-G and HLA-E, favoring the evolution of infection, giving different degrees of gastric lesion in epithelium of these patients

Qualidade de vida de pessoas com úlceras venosas atendidos no ambulatório de um hospital universitário

Descriptive study aimed to analyze the quality of life (QOL) of patients with venous ulcers (UV) outpatient clinic of a university hospital in Natal / RN. The aim of the study population was composed of 50 patients with UV treated at the cardiology clinic of a university teaching hospital at the tertiary level. The study was approved by the Ethics Committee of the Federal University of Rio Grande do Norte (Protocol 279/09). Data collection was performed over a period of two months by the very a masters degree and an academic nursing through the application of a form concerning the socio-demographic, clinical, and health care, and the instruments WHOQOL and WHOQOL - old. The data were analyzed with SPSS 15.0, using descriptive and inferential statistics presented in the form of tables, charts and graphs. Of the surveyed, female predominance, age range 59 years, Catholic, low education, married, with up to 03 children, not working, retired, or with occupations requiring long periods in one position, wage income of up to 02 minimum wages, inadequate sleep, patients with chronic venous insufficiency and other chronic diseases such as diabetes and hypertension, were taking medications for treatment, being a minority to IVC. In patients with predominant only one injury, time of injury up to five years, inadequate rest, pain, edema and lesions colonized. The assistance the UV patients began treatment of the injury until four months after the onset of the ulcer, and services primary health care most wanted, access to angiologist by reference form, commuted by public transportation, received support regarding the treatment of injuries. The topical product most used in the lesion was healing, and few were using compression therapy. respondents suffer discrimination in society, showed changes in quality of life after the occurrence of ulcer in relation to leisure, pain, restriction of social / school / transportation; barring employment / financial / social ladder; Physical appearance / discrimination and restriction of domestic activity. These changes were related to the time of injury and found that the more chronic injury is the most negative changes occur in their QV (ρ = 0.000). Analyzing the characteristics of QV measured by the WHOQOL-bref, we found for the two general questions they are dissatisfied with their health (ρ = 0.023) and all areas have significant difference compared with the worst QV have the injury of more than 5 years (ρ = 0.000). The QV measured by the WHOQOL-old, we found that these patients had no changes from the time of injury. We conclude that the QV of patients with UV was considered unsatisfactory when compared to the time of injury on more than 5 years which shows that the quality of life worsens with time the chronic UV.

Custo-efetividade da terapia compressiva no processo de cicatrização de úlceras venosas

Analytical study of therapeutic nonrandomized intervention type, intra-group controlled, with the aim of analyzing the cost-effectiveness of compression therapy with manipulated Unna boot in relation to conventional therapy in the healing of venous ulcers (VU) of patients treated in ambulatory clinic. The study population was composed by patients with VU treated by angiologists in Surgical Clinic Ambulatory of the Onofre Lopes University Hospital (HUOL) with a sample of 18 patients. It obtained the assent of the HUOL Ethics in Research Committee (Protocol 276/09). Data collection was performed over a period of four months by the own master's student and 34 nursing students, through the application of the research instrument in the admission of patients to the study and in the ten subsequent evaluations, performed at the time of changing Unna boot, weekly, for a maximum period of 10 weeks. The data were analyzed with SPSS 15.0 software, using descriptive and inferential statistics, and presented as tables, charts and graphs. Among those surveyed, prevailed: females, mean age 57.6 years, low education and income levels, most retired, unemployed or off work, with the standing position more than six hours per day and up to eight hours daily of domestic or occupational activities. In health status profile of respondents there were predominantly sleep, rest and inadequate elevation of the lower limbs, no smoking and/or alcohol use, presence of hypertension and no use of drugs. Most presented the first VU for over 10 years, recurrences, present VU for more than five years, involvement of left leg, in malleolar and / or distal leg region, mild edema, hyperpigmentation, lipodermatosclerosis, telangiectasies, reticular and varicose veins, mild pain, serous exudate in moderate quantity, small lesions (up to 50cm2), with predominance of granulation tissue and / or epithelialization and demarcated, elevated and irregular borders, with crusts and macerated. Most patients reported that in the 10 weeks prior to admission, made bandages at home and / or Basic Health Unit and / or ambulatory, with nursing aides or technicians, daily, and on weekends or holidays, performed by patients themselves, using healing ointment on the lesion, being observed granulation / epithelialization and increase in VU prevalent in the 10 weeks of traditional treatment. After follow up with manipulated Unna boot, was observed a decrease of lesions in all study patients, with complete healing in 27.8% of those between 1 and 5 weeks of treatment, with satisfactory evolution of the lesions, pain and ankle and calf circumferences, and unsatisfactory development of the borders of ulcers, edema, sleep, rest and elevation of the lower limbs, especially in more chronic patients. Furthermore, patients who achieved total healing and exhibited the greatest percentage reduction of lesions had a higher number of wound healing factors (ρ = 0.01 and ρ = 0.027, respectively). The manipulated Unna boot showed better results in those patients with shorter duration of injury, leading them to a satisfactory outcome within a short period of treatment. After the cost-effectiveness analysis, we conclude that the manipulated Unna boot is more effective than conventional therapy in the healing process of VU and is more cost-effective in patients with shorter lesions (ρ = 0.001), shorter treatment (ρ = 0.000) and greater number of wound healing factors (ρ = 0.005).

Assistência aos portadores de úlceras venosas: proposta de protocolo

Venous ulcers (VU), recurrent chronic wounds resulting from Chronic Venous Insufficiency (CVI), affect different age groups and would severely affect ambulation of patients. The lesions require treatment lasting and complex and are responsible for significant morbidity and mortality. Thus, this study aims to identify the important aspects covered in the scientific literature protocol for assisting patients with venous ulcers, identifying the issues to be proposed by the judges of the study (nurses, doctors and physiotherapists) to the protocol of care provided to patients venous ulcers and present the structure of protocol proposed by the judges of the study to assist patients with venous ulcers treated at a referral hospital of Rio Grande do Norte. This is a descriptive study using a quantitative approach, carried out at the dressings, located in the outpatient surgical clinic of the Hospital University Onofre Lopes (HUOL), located in East Sanitary District, Natal-RN. The sample consisted of 39 professionals, 30 nurses, seven doctors and two physical therapists, team members HUOL surgical clinic and other public and private institutions of Rio Grande do Norte and Jequié/Bahia. These professionals were the judges responsible for selecting the guidelines already proposed in the literature on VU protocols. Approved by the Ethics in Research HUOL (Report n.o 081/07), began the first stage of the study which consisted of reviewing the scientific literature about the relevant aspects to be included in a protocol for assisting patients with VU. These aspects were organized into a proposed questionnaire to the judges of the study. Following examination, held on the content validation with application of the Kappa (K), accepting a score higher than 0.80 and the Likert Scale, whereas rates from 4.0 to 5.0. The data collected were organized in Microsoft Excel and exported into Statistical Package for Social Sciences (SPSS) 15.0. The literature review included national and international scientific articles, thesis, dissertation and institutional protocols. Regarding the characterization of professional nurses predominated (76.1%), between 34 and 45 years (41.0%), female (79.5%), married/consensual union (46.2%), with specialization in VU care (61.5%), working in the hospital network (46.1%), with up to 5 years experience in VU (69.2%) and claiming to feel prepared to care for these injuries (92.3 %). With regard to aspects that had very good agreement (K ≥ 0.81), remained the items found in the literature with some modifications. In the analysis of the proposed evaluation items had very important, ranging from 4.1 (drug treatment) to 4.9 (patient assessment and care of the injury and the injured and perilesional skin). The proposition of the protocol is arranged in eleven items: A) Evaluation of patient and lesion, B) Registration and documentation, C) the wound and perilesional skin, D) an indication of coverage, E) Use of antibiotic and pain treatment, F) Surgical treatment of CVI, G) Drug treatment, H) Improving venous return and prevetion of recurrence, I) Referral of patients, J) Training and K) Reference and counter reference

Qualidade de vida de pessoas com úlcera venosa: associação dos aspectos sociodemográficos, de saúde, assistência e clínicos da lesão

Venous ulcer (VU) is a lower limbs injury resulting from inadequate return of venous blood in feet or legs. Although it is not a deadly disease, it causes chronic wounds, which seriously undermine patients´ quality of life (QOL) and sometimes leads to drastic family, social, economic and psychological changes. In this sense, there are several aspects that may influence the venous ulcers patients´ QOL. The study´s objective aimed on the association of socio-demographic and health, health care and clinical injury on UV patients‟ QOL. Analytical studies, which consider the complexity of factors involved in changes in UV patients‟ QOL has a cross-sectional and quantitative approach. The HUOL Ethics Committee approved this project (n.279/09). The collection of data lasted a period of 3 months in 2010 and it took place at the clinic of Angiology at Hospital Universitário Onofre Lopes (HUOL). The data sample consisted of 60 patients treated by UV angiologists in the HUOL Surgical Clinic. The results were analyzed with SPSS 15.0 by descriptive and inferential statistics. The study was based on UV patients that were predominantly female, average age of 61.4 years, that had low education level and low family income, with occupations requiring long periods of standing or sitting, but mostly retired, unemployed or laid off due to the disease and/or due to chronic diseases associated with the UV. The study took also into consideration patients that used inappropriate products, that were improperly treated by a professional caregiver, that lacked of adequate guidance and compression therapy, that performed no lifting of the lower limbs and regular exercise, that the time of injury were greater than or equal to six months, that were missing specific laboratory tests. The study‟s reference were on recurrent lesions, medium to large lesions area, bed of the lesion (injuries) with fibrin and/or necrosis, with amount of exudate with medium to large, odorless and no signs of infection, with tissue loss between 1st and 2nd degree, without collecting swab or biopsy and with pain. In general, QOL of researched individuals were considered low, the maximum score was 69 points, which the areas that were mostly influenced were the total scores of QOL functional capacity (0.021), emotional (0.000) and social functioning (0.080). Of the 60 individuals, 53.3% had scores between 40 and 69 points in SF-36, and they had the best scores in sociodemographic and health variables (ρ = 0.049). In respect to the assistance and injury characteristics, patients who scored between 40 and 69 points in SF-36 had better scores on these characteristics. By combining the socio-demographic variables, health, and handling characteristics of the injury, we observed a significant difference (ρ = 0.032) when linking them with the QOL total scores. When analyzing separately the domains of the SF-36 scores on the quality of life, we find that the areas that showed statistical significance were functional ability (ρ = 0.035), appearance (ρ = 0.019), emotional (ρ = 0.000), and mental health (ρ = 0.050). Among the socio-demographic characteristics studied, gender and marital status contributed more to the reduction of QOL and among the variables of assistance and the injury, orientation, reference and area of UV contributed the most. By analyzing these five variables all together in accordance with the overall score obtained in the quality of life, we found a significant correlation (ρ = 0.002); with 6.23 times more chances of patients have better QOL in the presence of these five positive factors. By conducting the Mann Whitney U test between all the five demographic variables, health, and clinical care, we found that this combination also proved to be significant (ρ = 0.006). Therefore, patients with these five variables positive tend to have a better QOL. Based on these results, we reject the null hypothesis (H0) and accept the alternative hypothesis (H1) proposed in this study because we noted that the QOL of patients with UV is associated with sociodemographic and health, health care and clinical aspects of the injury

Validação de protocolo de assistência para pessoas com úlcera venosa na atenção primária

People with venous ulcers constitute as an important public health problem, its treatment is onerous and require assistance provided by trained professionals, systematized through protocols, however what lies in the assistance is that the management of this group of people differs from that preconized in the scientific literature, interfering with wound healing and quality of life of affected. In this sense, the construction of a assistance protocol specific to people with venous ulcers (VU) can help professionals of the Family Health Strategy both in patient assessment as and in establishment of quality assistance. Thus, this study aimed to analyse the validity of a multiprofessional assistance protocol for people with venous ulcers in primary care by health professionals using Delphi technique. This is a quantitative study, the methodological type conducted in two steps: first step related to integrative literature review to subsidize the development of the protocol, then these aspects were organized and proposed to the judges of the study through the Delphi technique. The study was initiated after approval by the Research Ethics Committee. The first step was performed between August and September 2012, in the virtual library of health, in the page of the Coordination of Improvement of Higher Education Personnel, of Municipal Health Secretariat and international guidelines of associations and in the subsequent step carried out between September 2012 to January 2013, was performed search by Lattes platform of the National Council of Technological and Scientific Development, in order to identify health professionals in Brazil who act as judges of the instrument and then, via online, the form was submitted to them.The sample for the second step was 51 judges in the first round and 35 for the second round Delphi. The analysis was done by adopting Kappa index ≥ 0.81 and Content Validity Index (CVI)> 0.80. In the first submission for the judges, items that did not reach Kappa and CVI established were: request / realization / test results, demographic data, medical history, risk factors, verification of pain / vital signs / pulse / infection signs / lesion location/ edema and pain treatment. After removal of items which have not obtained Kappa or CVI index established, it was found achieving optimal levels of these index for the categories. In the next step was the ressubmissão of protocol to judges through the Delphi technique in it was found that, of the 15 categories of the protocol, 12 presented higher scores in Delphi 2 phase and the other three categories remained the same Kappa and IVC of the previous phase. As for the average of evaluation requirements of the protocol was found that the scores assigned by the judges were higher in the second phase in nine of the 10 items, remaining the same in only one of the items indicating validity of the instrument before the consensus of the judges. Thus, we accepted the alternative hypothesis in this study, as they were obtained in the second Delphi phase the validity index greater than or equal to the Delphi 1 phase. The formulation of this assistance protocol valid and reproducible will enable a reorganization and redesign of assistance, with standardization of actions and continuity of care for persons with venous ulcers in primary health care

Controle da neoplasia maligna do colo de útero: a resolutividade na atenção básica

A quantitative, descriptive, cross-sectional and retrospective study, using technical procedures of document consultation from secondary sources and health household survey with application form for face to face inter views, with the assent nº.039/2011 from the Ethics Committee of the Federal University of Rio Grande do Norte. The aim of this study was to analyze the cervix cancer control in the area47 of the Health Family Centre Nova Natal II. The cancer cervix is the second most common cancer among women worldwide. In Brazil screening for early detection and treatment of disease has been poorly done and follow-up to reduce mortality has not been executed. From a total of1170women belonging to area 47, who under went screening by the Pap test in the period from 2005 to 2010,was elected a sample of 38 women with positive cervical changes, over 18 years old. The calculation of frequency analysis of socio demographic and clinical and epidemiological selected variables with the results of cervical changes, using the X2 test and taking as significance level of p<0.05 was not statistically significant. The predominant age range was 25 to 64 years (68.9%), most no white women (60.5%), predominantly with primary education (57.9%), most married (68.4%) and housewives (68.4%) with early age of sexual activity (86.8%), the minority smokers (13.2%), with a sexual partner (36.8%). At the time of interview, 42.1% of the women voiced complaint of discharge, while only 2.6% reported bleeding. In relation to the occurrence of STDs (including HPV), 10.5% of women reported being a carrier. The use of oral contraceptives was 32.3% of women, from 2 to 4 years (44.4%). The result of the last screening test performed, showed prevalence of immature squamous metaplasia (55.3%), followed by intraepithelial low- grade lesion (including the cytopathologic HPV effect and cervical intra epithelial neoplasia grade I) (31.6%); intraepithelial high-grade lesion (including cervical intraepithelial neoplasia grade II and III) (7.9%), atypical squamous non neoplastic cells (5.3%). There was no squamous cell carcinoma and adenocarcinoma. Most women received information about the action that should be done after the last screening test result (55.3%), but how to perform follow, most women did not report having done so (55.3%). The follow-up group of women studied, with varying degrees of cervical abnormalities, should only be completed with the discharge by cure, established inconsecutive negative cytology, a goal that is not being achieved in the area 47 of the Health Family Centre of Nova Natal II

Autoestima e qualidade de vida de pessoas com úlcera venosa atendidas na atenção primária

Venous ulcers (VU) is a chronic injury of the lower extremities and because of its high incidence and recurrence implies long and complex treatments, damaging the quality of life (QOL) and self-esteem (SE) of the people. This study aimed to analyze the association between self-esteem with the quality of life of people with venous ulcers treated in primary care. Cross sectional analytical study with a quantitative approach conducted with 44 people met with VU at 13 primary care units 2 and Mixed units in Natal/RN. The study was approved by the Ethics Committee in Research of the Federal University of Rio Grande do Norte (UFRN), CAAE: 07556312.0.0000.5537. Held data collection from February to April 2014 and used three instruments: a structured form covering sociodemographic, health care and clinical variables, the Rosenberg Self-Esteem Scale and the SF-36. The collected data were entered into a database and processed on computerized software for descriptive and inferential analyzes. The results showed a predominance of people with UV females (65,9%), with more than 60 years (59,1%), married or in a stable relationship (52,3%), low education (86,4%) without occupation (68,2%) and less than one minimum wage income (81,8%). Regarding assistance characteristics was observed that most patients performed the dressing with appropriate material (72,7%), professional or trained caregiver (61,4%) did not use compression therapy (81,8%), treating the injury for more than 6 months (77,3%), lack of guidelines for the use of compression therapy, elevation of legs, and regular exercise (77,3%) and consulting the angiologist last year (52,3% ). Regarding clinical features of the lesion was found that most of the recurrent lesions are (77,3%), over one year of current lesion (52,3%) medium to large lesions (54,8%), without signs of infection (61,3%) and pain (79,5%). The mean SE of respondents was 9,3 (± 5,1). The relations between the SE and the sociodemographic variables, health care and clinics showed that individuals without a partner (a) (p = 0,01), who did not wear compression therapy (p = 0,04), with more 6 months of treatment (p = 0,01) and larger lesions (p = 0,01) had a lower SE. The mean domain and the dimensions of the SF-36 were lower emphasizing the functional capacity 36.5 (± 27,6) and the physical aspects of 15.3 (± 30,6). There were significant correlations between AE people with VU and the domains and dimensions of the SF-36: physical functioning (r = -0,432), general health (r = -0,415), vitality (r = -0,573), aspects social (r = -0,517), mental health (r = -0,612) and mental health dimensions (r = -0,612) and physical health (r = -0,473). Based on these results it is concluded by rejecting the null hypothesis and accept the alternative proposed in the study in which it was found that there is a negative correlation between the SE and the QOL of people with venous ulcers

Caracterização dos genes scMUTM1 e scMUTM2 de cana-de-açúcar

Plants are organisms sessile and because of this they are susceptible to genotoxic effects due to environmental exposure such as light [including ultraviolet (UV)], heat, drought and chemicals agents. Therefore, there are differents pathways in order to detect a lesion and correct. These pathways are not well known in plants. The MutM/Fpg protein is a DNA glycosylase that is responsible for detect and correct oxidative lesions. In the sugarcane genome, it was found two possible cDNAs that had homology to this protein: scMUTM1 and scMUTM2. The aim of this work was to characterize the role of these cDNAs in plants. In order to do this, the expression level after oxidative stress was evaluated by semiquantitative RT-PCR. Another point analyzed in order to obtain the full-length gene, it was to use a sugarcane genomic library that was hybridized with both cDNAs as a probe. It was found two clones that will bought and sequenced. The promoter region was also cloned. It was obtained sequences only for scMUTM2 promoter region. The sequences obtained were divided into six groups. It was found regulatory motifs such as TATA-box, CAAT-box, oxidative stress element response and regulatory regions that response to light. The other point analyzed was to characterize the N-terminal region by PCR constructs. These constructs have deletions at 5 region. These sequences were introduce into Escherichia coli wild type strain (CC104) and double mutant (CC104mutMmutY). The results showed that proteins with deletions of scMUTM1 N-terminal region were able to complement the Fpg and MutY-glycosylase deficiency in CC104 mutMmutY reducing the spontaneous mutation frequency

Recidiva de câncer labial em pacientes atendidos no hospital DR. Luiz Antônio (Natal-RN) entre 1997-2004

Introduction: Cancer of the lip is very common in tropical countries, being noticeable the squamous cell carcinoma as the main histological type. Objective: Evaluate the socialdemographic profile, habits, occupation, clinical characteristics of the cancer lesions and the aftermath of treatment of the patients treated on the Luiz Antônio Hospital (Natal-RN). Design: Retrospective cohort. Methods: We analyzed 181 medical records of patients from the Luiz Antônio Cancer Hospital (Natal-RN) in the period between 1997 and 2004. The statistic evaluation of time between the diagnosis and the relapse or the cure of the patient were done through the Kaplan-Meier method and the comparison of survivor functions were done through the Log-rank test. Later, was estimated the proportional risk model of Cox. Results: The study population were composed by 69,1% males, 95,2% unlettered, the mean age of 66,5 years, 89,0% of smokers and 64,1% had an occupation involving sun exposure. In regard to the clinical characteristics, most lesions were in the lower lip (77,9%), the size of the tumor was smaller than 2 cm (51,8%), 92,6% had localized lesions. Were verified 16,3% of local relapse and 13% of regional. Almost the totally of the cases corresponded to squamous cell carcinoma (97,2%). We observed smaller accumulated probability of not occurrence of local relapse when the base and borders were free of lesions (p=0,041), as well as a smaller probability of regional relapse when the sort of treatment was surgery, associated with other therapeutics modalities (p=0,001). The patients with advanced pathologic stage (p=0,016), treated with surgery associated with other therapeutics modalities (p=0,001) and diameter above 4cm (p=0,019) presented a bigger possibility of any kind of relapse. The multivariable analysis pointed the complex treatments (surgery plus other therapeutics modalities) as a predictor variable for occurrence of new local lesions (p=0,001) and total (p=0,046), besides the age above 70 years to the regional relapse (p=0,050). Conclusion: Cancer of the lip occur in the lower lip, in males, smokers and individuals exposed to Sun light. The relapse was frequent, even being localized and without great consequences to the patient s health. The probability of relapse is related to the size and borders of the lesion and to the histological exam, as well as to the patient s age and complexity of the treatment chosen
