O idoso e as ações sociais em prol desse grupo etário: um estudo sobre a qualidade de vida na Terceira Idade e o Projeto Saúde e Cidadania na Melhor Idade

The present study regards an applied qualitative social research (descriptive) which approaches the matter between old age and Brazilian social actions performed in social projects, aiming a qualified life and citizenship for this group of age. The objective of the study is to evaluate the contribution of Project Health and Citizenship in Old Age regarding social actions from the government directed to old age individual treatment for life quality improvement. The theoretical fundamentals of this work is, in a first moment, about old age and certain existing theories about aging process, as well as the differences and perspectives that come up throughout this process. In a second moment, some reflections are developed about the relation between life quality and leisure regarding old age, with the conception and historical rescue about these questions, as well as the evidence of leisure as an instrument of well-being feasibility and a better life quality in old age. Then the study contextualizes Brazilian government treatment to old age individuals, cutting off the Constitution of Republic from 1988 and some social attitudes taken by the government in a try to reach this specific group. Finally, the study presents the Project Health and Citizenship in Old Age , as a social program which belongs to extension activities from Federal Center of Technological Education of Rio Grande do Norte (CEFET-RN), which aims old age treatment and their citizenship and life quality. After the application of a semi-structured interview using the technique of Analysis of content for the Analysis and Discussion of Results, it is possible to conclude that the Project Health and Citizenship in Old Age fulfils its objective regarding contribution, through offered leisure activities, for old age well-being and life quality improvement. Hence, on this regard, it is possible to observe the importance and value of government actions, social projects and programs assisting old age individuals, for they are able to provide this group the opportunity to live out activities that allow their citizenship and socialization, regarding well-being and life quality improvement.

Acesso aos serviços odontológicos e incidência de cárie em adolescentes e fatores de risco em município do Nordeste Brasileiro, 2006

The aims of this study were to analyze the access of dental services by child population, to determine the prevalence of dental caries, gingivitis and malocclusion in resident children from the municipal district of Sobral Ceará and to evaluate the incidence of the dental decay in adolescents associated with the factors related to socioeconomic condition, access to health services and self-perception. This study had as main factor the multidisciplinary represented by the participation of health professional (doctors, dentists, nurses) in the development of the survey's initial reference; student from Human Sciences area to apply the structured questionnaire in domiciliary visits; statistics professionals in the orientation of the analysis to be held and family health team (community health agents, dentists and dental clinic assistants) in the scheduling of domiciliary visits and the accomplishment of oral exam. The sample was determined from the domicile record that included children born between 1990 and 1994 to develop the research Children health conditions in the municipal district of Sobral Ceará . The first sample comprised 3425 parents of children from 5 to 9 years old, living in the urban area at the municipal district of Sobral Ceará, aiming at identifying the most important factors associated to the access to dental service. From this sample, 1021 children were selected in a systematic way, for the accomplishment to the epidemiological study of decay, gingivitis and malocclusion. In the study's third phase, in order to arrange the group to be followed, 688 adolescents were examined and interviewed, by means of the active search from the 1021 individuals that had been previously examined. It was observed that 50.9% of the children had access to dental service at least once in a lifetime. Of this total, 65.3% accomplished it during the last year, and 85.4% of these did in public services, what allows to identify the importance of this sector in the access to dental services. It was observed that the factors that most affected the access to dental 129 services were related to socioeconomic condition, such as the access to health plan, the possession of toothbrush, garbage collecting, mother s schooling, sewerage treatment and malnutrition. In relation to oral diseases, an increase in the DMF-T index according the age was observed, from 0.10 in five years old to 1.66 in the nine years old, while with the dmf-t index, the inverse happened, since the index decreased from 3.59 in five years old to 2.69 in nine years old. In relation to gingivitis, an average 32.7% of the children presented gum bleeding. In what concerns malocclusion, it was observed that 60.3% of the children didn't present any problem, 30.17% had light malocclusion and 9.5% severe malocclusion. The average incidence of dental caries was 1.86 teeth per youngster. Among the studied variables, tooth pain in the last six months, mother's income and school snack, adjusted by the perception about the need of treatment, the mother's schooling and the dentist's appointment at least once in a lifetime, were the variables that presented positive relationship with the high incidence of dental caries on this population by logistic regression. Variables of socioeconomic nature, related to the access to health services and behavior and biological variables presented a relationship with the high caries incidence. The study point out to the need of developing health actions in a humanized way, by an oral health team effectively bound to the population's interest, with the great objective to provide, with the public health services managers, adequate conditions to improve oral health

Influência de fatores biopsicossociais sobre a mortalidade de idosos no município de Santa Cruz/RN: um estudo prospectivo

The aging process if characterizes for a complex events network, from multidimensional nature, that encloses biological, social, psychic and functional aspects. The alteration of one or more aspects can speed up the aging process, anticipating limitations and until the death in the aged. For an adjusted confrontation of this question is necessary an interdisciplinary vision, in which the some areas of the knowledge can interact and with this to intervenes of the best possible form. Then, information derived from studies of aspects related to incidence, morbidity-mortality and transition patterns, involved in the health-illness process can more accurately identify risk groups thereby establishing links between social factors, illness, incapacity and death. Thus, this study aimed to identify, by a multidimensional vision, the risk factors of mortality in a coorth of elderly in a city in the interior of the state of Rio Grande do Norte (RN), Brazil. A prospective study carried out in Santa Cruz RN, where 310 elderly were randomly selected to form a baseline. The follow-up was 53 months. The predictive variables were divided into sociodemographic, physical health, neuropsychiatric and functional capacity. The statistical analysis carried out by bivariate analysis, survival analysis, followed by binary logistic regression and Cox regression, in the multivariate analysis, considering significant levels p < 0.05 and confidence interval (CI) of 95%. A total of 60 (19.3%) elderly died during the follow-up, where cardiovascular disease was the main cause. The survival was approximately 24.8 months. The study of general survival showed, at 12, 24, 36, and 48 months of observation, a survival rate of 97%, 54%, 31%, and 5% respectively, with a statistical difference in survival only observed for the variables of cognitive function and Basic Activities of Daily Living. In the logistic regression analysis, the risk factors identified were cognitive deficits (OR = 8.74), poor perception of health (OR = 3.89) and dependence for Basic Activities of Daily Living (OR = 3.96). In the Cox analysis, as well as dependence for Basic Activities of Daily Living (HR = 3.17), cognitive deficit (HR = 4.30) and stroke (CVA) (HR = 3.49) continued as independent risk factors for death. The risk factors found in the study can be interpreted as the primary predictors for death among elderly members of the community. Therefore, improvements in health conditions, with actions towards sustaining an autonomous life with special attention for elderly with cognitive impairment, could mean additional healthy quality of life, resulting in the reduction of premature mortality in this population

Mortalidade materna no estado da Paraíba, 2000 a 2004

Esta tese articulou as áreas do conhecimento da Epidemiologia, Saúde Pública, Demografia e Estatística. Para esta investigação, traçaram-se duas estratégias: por um lado, buscou-se relatar a trajetória dos direitos femininos em saúde no Brasil a partir do período pós-guerra até os dias atuais; por outro lado, objetivou-se analisar diferenciais da morte materna e suas associações com variáveis sociodemográficas das mulheres residentes no estado da Paraíba no período de 2000 a 2004. As explorações decorrentes destes objetivos resultaram na produção de três abordagens. Na primeira, procedeu-se a um olhar retrospectivo sobre as políticas de saúde da mulher no país e seus desdobramentos regionais, enfocando a saúde materna. A análise permitiu reconhecer que, apesar de todas as conquistas adquiridas pelas mulheres desde os anos 80, a população feminina brasileira, em particular a paraibana, ainda carece de melhorias nas condições de saúde, sendo esta situação retratada pelo elevado número de mortes maternas ocorridas nos últimos anos. Também se buscou retratar os esforços dos sistemas oficiais na luta pela melhoria da qualidade dos dados reconhecida, na agenda nacional, como sendo ainda uma grande preocupação atual. Na segunda, o objetivo foi identificar o poder associativo entre a raça das mulheres residentes no estado da Paraíba e algumas variáveis sociodemográficas. Os resultados mostraram que houve indícios significativos de que as mulheres não brancas da Paraíba tiveram maiores chances de morrer que as brancas com baixa escolaridade e por morte obstétrica direta. Na terceira, centrou-se no tipo de óbito materno, cujo objetivo consistiu em analisar associações entre o tipo de óbito materno das mulheres paraibanas e as variáveis: grupo etário, escolaridade e raça, no período de 2000 a 2004. Os testes estatísticos realizados apontaram que a mulher paraibana teve cinco vezes mais chances de morrer por morte obstétrica direta ou indireta na faixa etária abaixo dos 20 anos e acima dos 34 em relação a faixa etária entre 20-34 anos

Perfil epidemiológico dos distúrbios hipertensivos na gravidez

The preeclampsia is a disease that evolves to high death rate for the mother and for the fetus. The incidence of this disease in the world is variable and there are no data of this disturb in the Brazilian population. This paper had the objective to determine the incidence and risk factors for development of hypertensive disorders of pregnancy in a neighborhood in Natal, RN, Brazil, taking place a prospective study, cohort type, with the objective of evaluating the entire pregnancy of 242 women that got pregnant between 2004-2007. The incidence of hypertensive disorders was of 17%, while the incidence of preeclampsia was of 13.8%. The age average of women that developed the hypertensive disorders was of 27.4 years (SD±.9), whilst those that developed preeclampsia was of 26.6 (SD ±7.8) years and the normotensive was of 23.9 (SD±5.8) (p=0.002). It is noted a significant increase of the hypertensive disorder with age (p=0.0265). The gestational age for those who developed preeclampsia was lower than the women that developed normotensive pregnancy (p=0.0002). The body mass index (BMI) of the group of women that developed the hypertensive disorder was of 25.8 (SD±3.9), significantly higher than the group of normotensive women with 23.5 (SD±3.7) (p=0.02). The levels of triglycerides and cholesterol tended to be higher on women with preeclampsia than on normotensive, p=0.0502 and p=0.0566, respectively. Six (6) women presented with severe preeclampsia and one (1) developed HELLP Syndrome. The resolution of the pregnancy was performed by cesarean section in 70% of women that developed hypertensive disorders, whilst the normotensive was of 23.6% (p<0.0001). A subgroup of the studied subjects was reassessed one year after labor, revealing that 50% of the patients were still hypertensive. There were no larger complications nor mother death during labor. The incidence of hypertensive disorders are above the levels noted in other studies and 30% of the women were within the poles of greater risk for the hypertensive disorders; the elevated BMI in the beginning of the pregnancy is a risk factor for hypertensive disorder. The risk of severe complication in preeclampsia is high, with imminence of eclampsia occurring in 20.1% of women who developed hypertensive disorder of pregnancy. The adequate prenatal care and the opportune labor assistance may minimize the complications of the pregnancy hypertension and avoid mother death, although the risk of women remaining hypertensive is elevated

Marcadores nutricionais e inflamatórios e sua associação com a morbimortalidade em hemodiálise

Background: Malnutrition, inflammation and comorbidities are frequent in patients with chronic renal failure in hemodialysis (HD), contributing for morbidity and mortality. Aims: To evaluate the correlation between anthropometric, laboratory parameters, bioelectrical impedance (BIA) and inflammatory markers with the morbidity and mortality of patients in HD, as well as the impact of its alterations throughout 12 months. Methods: 143 patients of a dialysis facility in Northeast Brazil were evaluated throughout 18 months. Patients with more than 3 months on dialysis, older than 18 years, without amputation of hands and feet, were included in the study. We performed a clinical (subjective global assessment - SGA), anthropometric (BMI, percent of ideal weight, MAC, MAMC, MAMA, percent of fat mass and TSF), laboratory (albumin, creatinine, lymphocyte count as nutritional markers and CRP, IL-6 and TNF- as inflammatory markers) evaluation and BIA (reactance, phase angle and percent of body cell mass) at the beginning of study and after 3, 6 and 12 months of follow-up. The association between study variables and deaths and hospitalizations in 6 and 12 months was investigated. The variable with significance < 10% in the univariate analysis had been enclosed in a multivariate logistic regression analysis. We also investigated the risk of mortality and hospitalization associated with differences in measurements of the variables at baseline and six months later. Results: Patients were aged 52.2 ± 16.6 years on the average, 58% were male, and mean dialysis vintage was 5.27 ± 5.12 years. The prevalence of malnutrition varied from 7.7-63.6%, according to the nutritional marker. The variables associated with morbidity and mortality in 6 and 12 months had been creatinine ≤ 9.45 mg/dl, phase angle ≤ 4.57 degrees, BMI ≤ 23 kg/m2, age ≤ 64.9 years, reactance ≤ 51.7 ohms; Charlson´s index ≥ 4 and socioeconomic status ≤ 7. During six months of follow up, decrease in albumin was associated with significantly higher mortality risk. Conclusions: This study detected that the best predictors of morbidity and mortality between nutritional and inflammatory markers are phase angle, reactance, creatinine and BMI and that changes in albumin values over six 107 months provide additional prognostic information. The authors believe that parameters of BIA may detect early changes in nutritional status and emphasize that longitudinal studies with larger number of patients are necessary to confirm these data and to recommend BIA as a routine nutritional evaluation in HD patients

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

Determinantes envolvidos na resposta imune celular humana à infecção por Leishmania infantum chagasi

Visceral leishmaniasis (VL) is a disease caused by protozoa of the Leishmania donovani complex, whose infection has clinical spectrum ranging from asymptomatic infection to active disease characterized by fever, cachexia, hepatosplenomegaly, and immunosuppression. The healing or protective immunity require an antigen-specific type 1. The Montenegro skin test (DTH) has been interpreted as a marker of protective immunity. However, there is no known correlation between the DTH response to type 1 and DTH and immunity of type 1 are maintained in the long term. Thus, a longitudinal study of 8 years, nested in a cohort family held in Brazil, documented the status of DTH and cytokine production by peripheral blood mononuclear cells in response to antigen-specific stimulation. This study was the interdisciplinary approach of physicians, biochemists, nutritionists, veterinary medicine, biology and statistics. The results show that 46.2% of subjects were analyzed DTH positive at baseline. The prevalence of positive and DTH induration size increased with age (p = 0.0021). 15.7% of individuals positive DTH "retro-converted" the negative and 50.4% (64) of individuals negative DTH became positive. The size of DTH induration was correlated significantly with the antigen-induced production of IFN-γ (r = 0.6186, p = 0.0001). IL-6 was secreted at higher levels in peripheral blood mononuclear cells of individuals who "retro-converted" DTH positive to negative than individuals who remained stable DTH status (p = 0.005). Thus, IFN-γ produced by peripheral blood mononuclear cells, may be a surrogate marker for protective immunity instead of the DTH response. In addition, differences in innate immune response may determine whether individuals maintain or eliminate the infection by Leishmania infantum chagasi in asymptomatic patients

Aspectos ambientais e sociais envolvidos na transmissão da L. chagasi no município de Parnamirim/RN

Visceral leishmaniasis hás adapted in the past 20 years to periurban and urban areas, and in Natal, Rio Grande do Norte, it became endemic. Thid study aimed to evaluate the environmental and social aspectsof Leishmania chagasi infection and its epidemiologic transmission chain in an urban, periurban and rural area of Parnamirim-RN. A study with three sections was conducted: Section 1: Sectional study of the human and canine infection by L. chagasi and its environmental and social determinants. Section 2: Observational longitudinal cohort to evaluate the dynamics of the canine infection. Section 3: Longitudinal study to evaluate the behavior of Lu. Longipalpis vector and the seasonal factors related to its dynamics. To include in the study the hauses were randomly selected and georreferenciated. Montenegro skin test was done in the human population and blood samples were collected for anti-Leishmania antibody detection. The canine population was examinated for L. chagasi infection by RIFI, ELISA and ELISA for rK39. An entomologic surveillance was monthly done with CDC light trapsin 10 houses of each locality. Quantitative and qualitative analyses was done using STATISC 6.0. Probality and prediction maps were done using ArcGis 9.0 model. In the human population L. chagasi infection was associated with the area of the hause, age, sex, population densyti, vegetation, kind of the floor of thr hause, water and resides destiny. In the canine population L. chagasi infection was associated with the breed, size, time of living in the hause, presence of dogs in the neighborhood, presence of horses and donkeys in the neighborhood, vegetation, kind of the floor and walls of the hause. The human infection was associated with canine infction only when analyzed taking into account the locality. In the prospective study, serum conversion and antibody lost observed in 30,8% and 22% of the animals examined, respectively. The human infection rate by L. chagasi was 24,6%, by the presence of anti-Leishmania antibody and 38,6% by the Montenegro skin test. The canine infection rate 32,5% by the presence of anti-Leishmania antibody. The vector Lu longipalpis showed an atypical behavior. These results indicate that environmental and social factors are important variables associated with L. chagasi infection in humans and canines, with punctual association of thr last two. Control measures of the infection on the studied points are necessary, in the aim to reduce the endemic focus of the disease in the study area. This research was carried out in a multidisciplinary involving the categories of: doctor, biologist, veterinarian, statistical, pharmaceutical and biochemical

Risco de doença cardiovascular em mulheres com história de distúrbio hipertensivo da gravidez

OBJECTIVE: Preeclampsia is a disease that can lead to a high maternal and infant morbidity. Worldwide, the incidence of this disease is highly variable and there is no data on this disorder in the Brazilian population. This study aimed at determining incidence and risk factors in the hypertensive disorders during pregnancy in a neighborhood of Natal, in addition to observing the evolution of these disorders one year and five years after delivery. METHODS: Prospective cohort study to assess the outcome of pregnancies of 242 women who became pregnant between 2004-2007 in the neighborhood of Bom Pastor in the city of Natal, state of RN, Brazil. Five years after delivery, there was an active search of thirty-nine (39) women who became pregnant and had a hypertensive disorder during pregnancy and/or pré-eclâmpsia, out of the total of 242 participants in the initial study. We administered a structured questionnaire to obtain basic information about the current clinical situation of patients and occurrences of subsequent pregnancy and presence of hypertensive disorders during pregnancy. We also searched for information on the use of hypotensive drugs and contraceptives. The following characteristics were checked and recorded: a) current weight, b) blood pressure c) body mass index - BMI, and we collected biological samples (blood and urine) for measurement of biochemical parameters and evaluation of microalbuminúria. Finally, we monitored the ambulatory blood pressure (ABP), which uses the method of automatic measurement of heart rate, systolic and diastolic blood pressure and an average of the two for the period of 24 hours. RESULTS: Out of 218 women who completed the study, the incidence of hypertensive disorders was of 16.9% (37 out of 218), while the incidence of preeclampsia was 13.8% (30 of 218). Women with preeclampsia had a BMI (body mass index) averaged of 25.3 (± 4.8) while this ratio in normotensive women was of 23.5 (± 3.7), p = 0.02. The risk of preeclampsia rises with age (OR 1084 p = 0.0034) and with a family history of hypertension (OR 2.6 p = 0.01). The follow-up one year after delivery revealed that 50% of women with hypertensive disorders in pregnancy remained hypertensive. High BMI was also observed after 5 years of delivery. CONCLUSIONS: an elevated BMI, age above 35 years and excessive weight gain during pregnancy were associated with hypertension in the long term in patients with prior preeclampsia. History of preeclampsia increases the risk of chronic hypertension

Iga total e específica para bactérias enteropatogênicas no colostro e leite de mães da zona rural da Paraíba

Trata-se de um coorte prospectivo com amostras de leite de 28 mães da zona rural da Paraíba, durante diferentes dias de amamentação exclusiva, com objetivo de avaliar através do ensaio imunoenzimático a presença de imunoglobulina A secretora (sIgA) total e específica contra antígenos de Escherichia coli enteropatogênica (EPEC) e Shigella flexneri. A reatividade dos anticorpos foi analisada pelo Western blot . Os resultados mostram presença da sIgA em todas as amostras, com medianas no colostro de 8,092 g/L(4,546-17,252) e leite de 0,695g/L (0,020-2,830). As medianas nos títulos de colostro de IgA anti-EPEC foi 41 (1-659) e anti-Shigella flexneri de 18 (1-4727) enquanto no leite anti-EPEC foi de 8 (1-288) e anti-Shigella flexneri de 6 (1-450). Houve grandes variações entre as mães e entre os dias de amamentação. No Western blot os anticorpos sIgA reagiram com proteínas de EPEC e Shigella flexneri, destacando-se a fração antigênica de 94kDa, correspondente a intimina. Os resultados mostram que a presença de sIgA total e de anticorpos IgA contra EPEC e Shigella flexneri no colostro e leite de mães residentes em zona rural, com precárias condições sócioeconômica e sanitárias, não diferem de estudos realizados com populações de área urbana e reforçam a importância do leite materno na defesa contra infecções entéricas. Apesar da ausência na literatura de estudos avaliando o perfil de anticorpos sIgA no leite de mães residentes em zona rural do Brasil, os resultados demonstraram que a presença de sIgA total e de anticorpos IgA contra EPEC e Shigella flexneri no colostro e leite de mães residentes em zona rural, com precárias condições sócio-econômica e sanitárias, não diferem de estudos realizados com populações de área urbana e reforçam a importância do leite materno na defesa contra infecções entéricas

Aleitamento e infecções por parasitas intestinais em gestantes adolescentes e seus filhos

The exclusive breastfeeding in the first six months of life practice is essential for the health and development of children. Studies show there is in human milk protective antibodies against intestinal parasites and a relationship between the absence of breastfeeding or weaning and parasitic infections. This work was a prospective cohort study involving 34 pregnant adolescents attended school in Maternity Januario Cicco / RN and their children, to assess the influence of breastfeeding on intestinal parasites in them. Thus, the parasitic infection was investigated by examination of feces parasitological and environmental factors by use of questionnaires. The average age of the mothers studied was 16.2 years. Of these 76.4% were infected and the most prevalent species of parasites were Entamoeba histolytica/dispar (76.9%), Giardia lamblia (19.2%) and Ascaris lumbricoides (11.5%). The infected children had an average age of 5.1 months and the frequency of parasites was 61.7%. The infection was earlier detecctada with 45 days of life. The most common parasites were Giardia lamblia (40%), Entamoeba histolytica/dispar (35%), Ascaris lumbricoides (5%) and Ancylostoma (5%). The average length of exclusive breastfeeding was 2.2 months. There was an association between increased duration of exclusive breastfeeding and increased time to detection of parasites in the feces of children. There was no statistically significant correlation between the socio-economic conditions and cultural and breastfeeding. The data reinforce the importance of breastfeeding to protect the children in its first year of life

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
