Genotoxicity of cigarette smoking in maternal and newborn lymphocytes.

Tobacco smoke contains a large number of substances known to induce DNA damage and to be hazardous to human health. Several reviews and meta-analyses have reported an association between maternal or paternal smoking habits and genetic-related diseases, such as cancer, in children. The aim of the present study was to evaluate the level of DNA damage in lymphocytes of active- and passive-smoking mothers and in their newborns, using the comet assay. A total of 40 active smokers, 40 passive smokers, and 40 non-smokers, and their respective newborns, were evaluated. The active smokers presented a statistically significant increase of DNA damage when compared to the non-smokers and passive-smokers. No significant difference was observed between passive and non-smoking women. Similar results were detected in newborns. Those born to active-smoking mothers presented higher levels of DNA damage than those from passive- and non-smoking mothers. Additionally, no significant difference was detected between newborns from non-smoking and passive-smoking mothers. Also, no statistically significant difference in DNA damage was observed between mothers and their respective newborns, and a positive correlation in the level of DNA damage was detected between them. Logistic regression analyses showed positive associations between DNA damage, spontaneous abortion and smoking status. In conclusion, our data indicate that tobacco exposure during pregnancy has genotoxic effects for both mother and child, and it can be considered an important risk factor for childhood cancer or other genetic-related diseases.

Prevention of "risky" drinking among students at a Brazilian university.

AIM: The aim of this paper was to compare the quantity and frequency of alcohol use and its associated negative consequences between two groups of college students who were identified as being "risky drinkers." Subjects were randomly allocated in a clinical trial to intervention or control groups. METHODS: Risky drinking use was defined as Alcohol Use Disorders Identification Test (AUDIT) >or=8 and/or Rutgers Alcohol Problem Index (RAPI) >or=5 problems in the previous year. Students who had undergone the Brief Alcohol Screening and Intervention for College Students (BASICS) (N = 145 at baseline; 142 at 12 months, and 103 at 24 months, loss of 29.7%) were compared with a control group (N = 121 at baseline; 121 at 12 months and 113 at 24 months, loss of 9.3%), the nonintervention group. Variables included drinking frequency, quantity and peak consumption, dependence assessment, and family and friends' abuse assessment. RESULTS: Treated students at a 24-month follow-up decreased quantity of alcohol use per occasion and lowered AUDIT and RAPI scores. CONCLUSIONS: This is the first brief intervention work on risky drinking with college students in Brazil and the results are encouraging. However, it is difficult to conduct individual prevention strategies in a country where culture fosters heavy drinking through poor public policy on alcohol and lack of law enforcement.

Sociodemographic and clinical characteristics, causal factors and evolution of a group of patients with chronic urticaria-angioedema.

CONTEXT AND OBJECTIVE: Chronic urticaria-angioedema is a common, multiple-cause complaint. The aim was to investigate the sociodemographic and clinical characteristics, causal and aggravating factors and evolution of urticaria-angioedema. DESIGN AND SETTING: This was a descriptive prospective study carried out at the Dermatology outpatient clinic of Faculdade de Medicina de Botucatu, Universidade Estadual Paulista (Unesp). METHODS: A total of 125 patients with chronic urticaria-angioedema were evaluated to obtain sociodemographic data, anamnesis, dermatological and general clinical data and laboratory data, emphasizing causal and aggravating factors and complaint evolution. RESULTS: Chronic urticaria-angioedema occurred mainly in females (mean age: 35 years), but also in men (mean age: 32 years). White color and living in urban areas also predominated. There was no preferential time for symptoms to appear, and nighttime was the most commonly reported time for clinical worsening. Around half of the patients had urticaria associated with angioedema. There were no associated factors in most of the cases, and stress was the most commonly reported aggravating factor. The cause was ascertained in 37.6% of our cases. The mean duration of follow-up was 11.7 months. Around 60% of the patients evolved with the problem under control, 32% improved, 9% had no change in dermatological condition and only one patient worsened. CONCLUSIONS: Chronic urticaria-angioedema was more common among middle-aged women. It is a long-term disease, and its cause was explained in about one-third of the patients. Half of the patients presented disease control after treatment lasting an average of approximately one year.

Efficacy of hormone therapy with and without methyltestosterone augmentation of venlafaxine in the treatment of postmenopausal depression: a double-blind controlled pilot study.

OBJECTIVE: This study evaluated the augmentation of venlafaxine with hormone therapy in the treatment of postmenopausal depression. The hormones evaluated were estrogen (0.625 mg) in combination with medroxyprogesterone acetate (2.5 mg) and methyltestosterone (2.5 mg). DESIGN: Seventy-two menopausal women (mean age: 53.6 +/- 4.27 years) diagnosed with depression (Montgomery-Asberg Depression Rating Scale [MADRS] scores > or = 20) were treated with venlafaxine and one of the following hormone therapy combinations, in a double-blind regimen: estrogen + medroxyprogesterone + methyltestosterone (group 1, n = 20); estrogen + medroxyprogesterone acetate (group 2, n = 20); methyltestosterone only (group 3, n = 16); and no hormone therapy (group 4, n = 16). Study duration was 24 weeks. Primary efficacy outcome was remission according to the MADRS, whereas secondary efficacy measures included the Clinical Global Impression (CGI), Blatt-Kupperman Index, and Women's Health Questionnaire (WHQ). RESULTS: Forty-eight patients completed the study. All groups showed significant improvement from baseline. Group 3 demonstrated significant improvement on the MADRS compared with placebo (group 4) at weeks 20 (P = 0.048) and 24 (P = 0.030); effect size 8.04 (0.83; 15.26) (P = 0.029), but also had the highest dropout rate. Groups 1 and 3 had significant CGI improvement rates compared with placebo: 42.23% (P = 0.012) and 44.45% (P = 0.08), respectively. There were no differences in the WHQ or BKI scores among the groups. CONCLUSIONS: Methyltestosterone 2.5 mg had the highest effect size compared with placebo, but the high dropout rate prevented its efficacy from being determined. Estrogen plus medroxyprogesterone, combined with methyltestosterone or otherwise, demonstrated a trend toward increased efficacy of venlafaxine. Further larger-scale clinical trials are needed to elucidate the findings of this pilot study.

[Geostatistical analysis of leprosy cases in the State of São Paulo, 1991-2002]. / Análise geoestatística de casos de hanseníase no Estado de São Paulo, 1991-2002.

OBJECTIVE: To analyze the spatial pattern of leprosy case occurrences in order to identify areas with a probability of disease transmission risks. METHODS: This was an ecological study in which the analysis units were municipalities in the State of São Paulo that were georeferenced at their centroids. The data source was the electronic database of notified leprosy cases at the Epidemiological Surveillance Center of the State of São Paulo, from 1991 to 2001. Geostatistical techniques were used for detecting areas with a probability of leprosy risk, and for quantifying the spatial dependency of cases. RESULTS: The spatial dependence detected extended outwards to 0.55 degrees from the georeferenced coordinates, which corresponded to approximately 60 km. The main areas identified as presenting a probability of risk were the northeastern, northern and northwestern regions of the State. CONCLUSIONS: Verification of areas with the probability of leprosy risk using spatial dependence analysis may be a useful tool for assessing health conditions and planning budget allocations.

Benefits of soy germ isoflavones in postmenopausal women with contraindication for conventional hormone replacement therapy.

OBJECTIVE: To evaluate the effects of isoflavones on vasomotor symptoms and blood lipids in postmenopausal women with contraindication for conventional hormone replacement therapy (HRT). METHODS: This prospective, double-blind and placebo-controlled study included 50 postmenopausal women randomly divided into two groups: 25 women on soy germ isoflavones (60 mg per day, capsules) and 25 women on placebo. Inclusion criteria included: non-vegetarian, non-asian women whose last menstruation dated at least 12 months prior to the beginning of the study, with FSH > 40 mIU/ml, hot flushes and contraindication for HRT, not using tamoxifen or antibiotic and no disease of the gastrointestinal tract. For 6 months, the Kupperman menopausal index (KMI), the vaginal cytological maturation value (MV) and both hormonal and lipid profiles were assessed. The t-test and analysis of variance (ANOVA) were employed to compare the two groups. RESULTS: In both groups, a decreased KI rate was observed. However, isoflavone was significantly superior to placebo in reducing hot flushes (44% versus 10%, respectively) (P < 0.05). After 6 months, the isoflavone group showed increased estradiol levels with unchanged FSH, LH, and vaginal cytology, and a reduction of 11.8% in LDL and an increase of 27.3% in HDL (P < 0.05 ). In the placebo group, just a reduction in MV was observed after 6 months (P < 0.05 ). CONCLUSIONS: Soy germ isoflavone exerted favorable effects on vasomotor symptoms and lipid profile, showing itself to be an interesting alternative therapy for the postmenopausal women with contraindication for conventional HRT.

[An analyze the opportunities of early detection of breast cancer]. / Análise das oportunidades de diagnóstico precoce para as neoplasias malignas de mama.

PURPOSE: The study tried to identify and to analyze the opportunities of early detection of breast cancer available for the women of Botucatu County. METHODS: A sample of 261 women, 30 year-old or more was interviewed by telephone. RESULTS: The age average was of 51 years; 49.45% of them studied at least 9 year; 80% received general orientations about breast cancer prevention and 86,9% specific orientations on self breast exam; 78.9% of the interviewers made the self breast exam, but only 27% made it correctly. The physician breast examination was made in 76.2% of the women and mammography in 35.6%; if physicians requested mammography exam and if it was available for all of them, 83.1% of the women would like to do it. CONCLUSION: The breast cancer prevalence and the mortality are higher in old women. This study showed that these women presented a smaller rate of opportunities for early detection, because they were less informed about the right periodicity of the self breast exam and they had less mammography and physician breast examination frequency than the younger. The school degree was also related, because the women with more years of study had better opportunities than the ones with less years of study.

Spatial distribution of trachoma cases in the City of Bauru, State of São Paulo, Brazil, detected in 2006: defining key areas for improvement of health resources.

INTRODUCTION: The objective of this study was to analyze the spatial behavior of the occurrence of trachoma cases detected in the City of Bauru, State of São Paulo, Brazil, in 2006 in order to use the information collected to set priority areas for optimization of health resources. METHODS: the trachoma cases identified in 2006 were georeferenced. The data evaluated were: schools where the trachoma cases studied, data from the 2000 Census, census tract, type of housing, water supply conditions, distribution of income and levels of education of household heads. In the Google Earth® software and TerraView® were made descriptive spatial analysis and estimates of the Kernel. Each area was studied by interpolation of the density surfaces exposing events to facilitate to recognize the clusters. RESULTS: Of the 66 cases detected, only one (1.5%) was not a resident of the city's outskirts. A positive association was detected of trachoma cases and the percentage of heads of household with income below three minimum wages and schooling under eight years of education. CONCLUSIONS: The recognition of the spatial distribution of trachoma cases coincided with the areas of greatest social inequality in Bauru city. The micro-areas identified are those that should be prioritized in the rationalization of health resources. There is the possibility of using the trachoma cases detected as an indicator of performance of micro priority health programs.

Rheumatic fever presentation and outcome: a case-series report.

OBJECTIVE: To assess the clinical characteristics and outcome of a rheumatic fever case-series from a referral hospital over the last 20 years. PATIENTS AND METHODS: Patients under the age of 18 years, diagnosed with rheumatic fever between 1986 and 2007 were retrospectively assessed to estimate the carditis and relapse rates, by use of descriptive and survival analysis. RESULTS: Of 178 cases identified, 134 were included. During the acute phase, 66.4% had polyarthritis, 56.8% had carditis, 28.6% had chorea, 1.5% had subcutaneous nodules, and 1.5% had erythema marginatum. The association of carditis and arthritis occurred in 40%. Carditis and chorea were more frequent among female gender. High antistreptolysin-O titres were found in 58.3%, and family history of rheumatic fever, in 14.5%. Mean follow-up was 6.8 years (1.1 to 16.9). Relapse was observed in 15%, hospital admissions in 27.6%, and follow-up discontinuation in 47.4% after a mean of 5.1 years. Carditis and relapse probabilities were 17.5% and 13.2%, respectively, five years after the initial attack. CONCLUSION: The risk of carditis and relapse of rheumatic fever was higher within the first five years. Follow-up discontinuation was frequent, pointing to the need of measures to improve adherence to prophylaxis and follow-up.

[Prevalence of trachoma among school children in Bauru: São Paulo State, Brazil]. / Tracoma em crianças do ensino fundamental no município de Bauru: Estado de São Paulo, Brasil.

PURPOSE: A survey was carried out with schoolchildren in Bauru, São Paulo State. The purpose of this study was to determine the prevalence of trachoma. METHODS: One thousand, seven hundred and forty-nine children from 6 to 14 years old were examined during the year of 2005. The schools were randomly chosen, according to the number of schoolchildren and the school region according to the local of the city (downtown, middle and periphery). The diagnosis was performed according to the World Health Organization (WHO) protocol and patients with clinical trachoma detection were submitted to laboratory confirmation by direct smear fluorescent antibodies cytology for Chlamydia trachomatis. RESULTS: Trachoma prevalence was 3.8%. Follicular trachoma was diagnosed in 3.7% of children, and intense trachoma in one child (0.06%). Children with trachoma were living mainly in the middle and peripheral region of the city, places with discontinuous water supply and absence of sewerage system in part of the residences. CONCLUSION: Trachoma prevalence in Bauru - São Paulo State - is 3.8%. The authors point out the survey results and also treated trachoma carriers. Other positive aspect of the survey was the community mobilization to prevent trachoma blindness.

OBJETIVO: Examinar as características clínicas de apresentação e desfecho em uma série de casos de febre reumática em um hospital de referência nos últimos 20 anos. PACIENTES E MÉTODOS: Pacientes com menos de 18 anos e diagnóstico de febre reumática, entre 1986 e 2007, foram avaliados retrospectivamente a partir da última consulta, para análise descritiva e de sobrevida, estimando-se a probabilidade de cardite e de recorrência. RESULTADOS: Dos 178 casos identificados, 134 foram incluídos. Desses, durante a fase aguda, 66,4 por cento apresentaram poliartrite, 56,8 por cento cardite, 28,6 por cento coreia, 1,5 por cento nódulos subcutâneos e 1,5 por cento eritema marginado; cardite foi associada com poliartrite em 40 por cento. Cardite e coreia predominaram no gênero feminino. Antiestreptolisina-O elevada ocorreu em 58,3 por cento dos pacientes, e história familiar de febre reumática em 14,5 por cento. O tempo de seguimento foi em média 6,8 anos (variando de 1,1 a 16,9 anos). Houve recorrência em 15 por cento dos pacientes, hospitalização durante a fase aguda em 27,6 por cento, e descontinuidade de seguimento em 47,4 por cento, após 5,1 anos em média. As probabilidades de cardite e de recorrência foram 17,5 por cento e 13,2 por cento, respectivamente, após cinco anos do surto inicial. CONCLUSÃO: Observou-se maior risco de evolução com cardite e de recorrências de febre reumática nos primeiros cinco anos. A descontinuidade de seguimento foi frequente, indicando serem necessárias medidas para melhorar a adesão à profilaxia e ao seguimento.

Tracoma em crianças do ensino fundamental no município de Bauru: Estado de São Paulo, Brasil / Prevalence of trachoma among school children in Bauru: São Paulo State, Brazil

OBJETIVO: Foi realizado um estudo transversal, por amostragem de escolares, frequentadores das escolas estaduais de Bauru, São Paulo, com o objetivo de detectar possíveis portadores de tracoma. MÉTODOS: Foram examinadas 1.749 crianças do ensino fundamental, de 6 a 14 anos, durante o ano de 2005. As escolas foram escolhidas por sorteio, de acordo com o número de estudantes e com a localização da escola dentro do setor da cidade (centro, região intermediária e periferia). O diagnóstico dos casos foi clínico, seguindo as normas da Organização Mundial de Saúde (OMS), confirmado laboratorialmente pelo método da imunofluorescência direta para detecção de Chlamydia trachomatis. RESULTADOS: A prevalência de tracoma inflamatório foi de 3,8 por cento, tendo sido diagnosticado tracoma folicular em 3,7 por cento e tracoma intenso em 0,06 por cento das crianças examinadas. As crianças com tracoma moravam principalmente na região intermediária e periférica da cidade, áreas onde o fornecimento de água pode ser descontínuo e o tratamento do esgoto pode estar ausente. Um programa de controle foi desenvolvido e os comunicantes foram diagnosticados e tratados. CONCLUSÃO: A prevalência de tracoma inflamatório em Bauru - Estado de São Paulo - é de 3,8 por cento. Além da oportunidade de reconhecer e tratar os portadores e contatantes, os autores realçam o fato positivo da mobilização da comunidade bauruense no sentido de prevenir a cegueira pelo tracoma.

Avaliação da qualidade da atenção básica em 37 municípios do centro-oeste paulista: características da organização da assistência / Evaluation of the quality of primary care health services in 37 municipalities in the State of Sao Paulo, Brazil: organizational dimensions of care

No Estado de São Paulo, existe uma rede extensiva de serviços de Atenção Básica (AB) com perfil organizacional heterogêneo e pouco conhecido. Este estudo objetiva caracterizar a organização dos serviços de AB em 37 municípios do Centro-oeste paulista, como primeira etapa de um projeto de avaliação da qualidade desses serviços. Trata-se de um estudo transversal conduzido mediante questionário estruturado, autorrespondido pelos gerentes e equipes locais, com questões que abordam características institucionais e de organização e gerência do trabalho. Esses questionários foram enviados para 131 UBS, distribuídas em 37 municípios. Obteve-se resposta de 113 unidades (87 por cento) localizadas em 32 municípios (86,4 por cento). Do total de unidades, 57 (50 por cento) são UBS tradicionais, 26 (22,8 por cento), Unidades de Saúde da Família, e 31, (27,2 por cento) organizadas segundo formas mistas. A maioria dos serviços (62 por cento, 70/113) não trabalha com área de abrangência delimitada de modo planejado. Os serviços se polarizam entre aqueles que realizam entre 70 e 100 por cento de consultas médicas agendadas (37,6 por cento, 41/109), e aqueles que realizam entre 70 e 100 por cento de não agendadas (39,4 por cento, 43/109). Não possuem conselhos locais organizados 65 unidades (63,7 por cento, 65/102). Os dados coletados permitem discutir as características dos principais programas, procedimentos e ações realizados pelos serviços. Os perfis organizacionais predominantes apontam a presença de deficiências de estrutura e processo em relação às diretrizes do SUS. O desenvolvimento de instrumentos de autoavaliação permite que as equipes se apropriem, de forma crítica, de seu trabalho, e possam elaborar novos arranjos tecnológicos para melhoria da qualidade.

CONTEXTO E OBJETIVO: Urticária-angioedema crônico é enfermidade freqüente, complexa e multicausal. O objetivo foi estudar as características sociodemográficas, clínicas, os fatores causais, agravantes e a evolução da enfermidade. TIPO DE ESTUDO E LOCAL: Descritivo e prospectivo, realizado no ambulatório de Dermatologia da Faculdade de Medicina de Botucatu, Universidade Estadual Paulista (Unesp). MÉTODOS: Foram avaliados pacientes com diagnóstico de urticária-angioedema crônico através de dados sociodemográficos, anamnese, exames dermatológico, clínico e laboratorial, com ênfase nos fatores causais, agravantes e na evolução da enfermidade. RESULTADOS: 125 pacientes foram incluídos, 95 mulheres e 30 homens. Predominaram mulheres de 30 a 40 anos e homens de 10 a 20 anos. A idade média foi de 35 anos para as mulheres e 32 anos para os homens. Predominaram pacientes de raça branca, residentes em zona urbana e casados. O tempo médio de doença foi de 45,6 meses e de cada lesão foi de 5,6 horas. A metade dos casos tinha surtos diariamente e associação de urticária com angioedema. Não houve horário preferencial de aparecimento dos surtos, mas o noturno foi o horário de piora mais citado. A causa foi esclarecida em 37,6 por cento, predominando as infecções. O estresse foi o agravante mais referido. O tempo médio de acompanhamento foi de 11,7 meses e 60 por cento evoluíram para o controle, 32 por cento melhoraram, 9 por cento mantiveram-se inalterados e um caso piorou. CONCLUSÕES: Urticária-angioedema ocorreu mais em mulheres de meia-idade. A causa foi esclarecida em um terço dos pacientes e metade deles teve controle da doença em aproximadamente um ano.

Análise geoestatística de casos de hanseníase no Estado de São Paulo, 1991-2002 / Geostatistical analysis of leprosy cases in the State of São Paulo, 1991-2002

OBJETIVO: Analisar o padrão espacial da ocorrência dos casos de hanseníase para identificar áreas com probabilidade de riscos de transmissão da doença. MÉTODOS: Estudo ecológico, tendo como unidade de análise os municípios do Estado de São Paulo georreferenciados em seus centróides. A fonte de dados utilizada foi o banco informatizado dos casos de hanseníase notificados do Centro de Vigilância Epidemiológica do Estado de São Paulo, no período de 1991 a 2002. Utilizou-se de técnicas de geoestatística para a detecção das áreas de probabilidade de risco para hanseníase e quantificação da dependência espacial dos casos. RESULTADOS: Detectou-se o alcance de dependência espacial de 0,55 graus de coordenadas georreferenciadas, correspondendo aproximadamente a 60 km. As principais áreas de probabilidade de risco encontradas foram as regiões nordeste, norte e noroeste do Estado. CONCLUSÕES: A verificação de áreas com probabilidades de riscos de casos de hanseníase, utilizando-se a análise da dependência espacial, pode ser ferramenta útil para avaliar a situação de saúde e planejar alocação de recursos.

Análise da distribuição espacial da hanseníase no Estado de São Paulo, 1991-2002 / Analysis of the spatial distribution of leprosy in The State of São Paulo, 1991-2002

A hanseníase no Brasil ainda é um problema a ser equacionado e, no Estado de São Paulo, há varias regiões com altas taxas de deteccão. O presente estudo objetivou analisar a distribuicão e quantificar a dependência espacial das taxas médias de deteccão da hanseníase no Estado de São Paulo, no período de 1991-2002, empregando técnicas geoestatísticas. Verificou-se tendência levemente decrescente das taxas médias de deteccão para o Estado de São Paulo. Altos índices do indicador podem ser visualizados nas regiões oeste e noroeste de São Paulo. A dependência espacial encontrada foi de aproximadamente 30 km. Com os resultados encontrados, conclui-se que a análise de superfície das taxas médias de deteccão pode auxiliar na escolha de áreas prioritárias visando aos exames de coletividade e ao incremento dos exames nos contatos dos casos detectados.

Prevalência do hipotiroidismo subclínico e repercussões sobre o perfil lipídico e massa óssea em mulheres na pós - menopausa / Prevalence of subclinical hypothyroidism and its effects on lipidic profile and bone mineral density in postmenopausal women

OBJETIVO: avaliar a prevalência do hipotiroidismo subclínico e suas repercussões sobre o perfil lipídico e a densidade mineral óssea (DMO) em mulheres na pós-menopausa. Métodos: trata-se de estudo transversal com recuperação de dados de prontuários de pacientes acompanhadas em ambulatório de climatério. Critérios de inclusão: mulheres na pós-menopausa com dosagem do hormônio estimulador da tiróide (TSH) e de tiroxina livre (T4-L). Critérios de exclusão: hipertiroidismo e carcinoma de tiróide. Considerou-se hipotiroidismo subclínico valores de TSH superiores a 5,0 mUI/mL e T4-L normal. Foram selecionadas 320 pacientes (idade 55,2±6,4 anos) divididas em 3 grupos: função tiroideana normal (n=208), hipotiroidismo subclínico (n=53) e hipotiroidismo clínico sob tratamento (n=59). Foram analisados dados clínicos, uso de terapia hormonal, índice de massa corpórea (IMC=kg/m²), perfil lipídico (colesterol total, HDL, LDL, triglicerídeos) e DMO da coluna lombar e fêmur. Na análise estatística, as diferenças entre as médias dos grupos foram comparadas utilizando-se a análise de variância (ANOVA). Para múltipla comparação, assumindo que a variância era diferente entre os grupos, utilizou-se o método de Tukey. RESULTADOS: o hipotiroidismo subclínico foi diagnosticado em 16,1 por cento dos casos. Os grupos foram homogêneos quanto às características clínicas, IMC e perfil lipídico e uso de terapêutica hormonal. Nas pacientes com hipotiroidismo subclínico ou clínico encontrou-se menor freqüência de osteopenia na coluna lombar e fêmur quando comparadas às eutiroidianas (p<0,001). Houve correlação negativa entre os valores de TSH e DMO da coluna lombar e fêmur (p<0,001). Não se constatou correlação entre os valores de TSH e idade, tempo de menopausa, IMC e perfil lipídico. O total de usuárias de terapia hormonal foi de 65,1 por cento, duração média de 3,43±2,42 anos, não diferindo entre os grupos. CONCLUSAO: o hipotiroidismo subclínico com prevalência de 16,1 por cento na pós-menopausa associou-se à baixa DMO, mas sem repercussões sobre o perfil lipídico

Influência da terapêutica hormonal prévia sobre os indicadores de prognóstico do câncer de mama em mulheres na pós-menopausa / Influence of previous hormonal therapy on breast cancer prognostic markers in postmenopausal women

OBJETIVO: avaliar a influência da terapêutica hormonal (TH) prévia sobre alguns indicadores de prognóstico do câncer de mama, em pacientes na pós-menopausa. MÉTODOS: estudo transversal por meio da aplicação de questionários e levantamento de prontuários. Foram entrevistadas 157 pacientes com diagnóstico de câncer de mama na pós-menopausa, registrando-se dados clínicos, antecedentes pessoais e familiares, uso de TH e mamografias. Nos prontuários foram obtidas informações sobre o câncer de mama quanto ao diâmetro do tumor, tipo de cirurgia e estudo imuno-histoquímico. Para a estatística empregou-se ANOVA e teste do chi2. RESULTADOS: 38,2 por cento das pacientes eram ex-usuárias de TH e 61,8 por cento não usuárias. O tempo médio de uso da TH foi de 3,7±3,6 anos. As ex-usuárias eram de menor faixa etária e com menor tempo de menopausa quando comparadas às não usuárias (p<0,05). Constatou-se que 26,8 por cento das pacientes apresentavam antecedentes familiares de câncer de mama, em ambos os grupos. Entre as ex-usuárias de TH, 43,3 por cento foram submetidas a mamografias prévias, ao passo que entre as não usuárias, apenas 11,3 por cento (p<0,001). O diâmetro médio do tumor foi menor entre as ex-usuárias de TH (2,3±1,1 cm), com predomínio de quadrantectomias (60 por cento), quando comparadas as não usuárias (3,3±1,5 cm e 32 por cento, respectivamente) (p<0,001). No estudo imuno-histoquímico, observou-se correlação positiva entre a presença de receptores de estrogênio e progesterona positivos e o uso de TH (p<0,001). Não houve correlação entre TH e c-erbB-2 e p53. CONCLUSAO: nesta casuística, as mulheres na pós-menopausa que usaram TH prévia ao diagnóstico de câncer de mama apresentaram indicadores de prognóstico mais favoráveis quando comparadas às não usuárias.

Análise das oportunidades de diagnóstico precoce para as neoplasias malignas de mama / An analyze the opportunities of early detection of breast cancer

OBJETIVOS: O estudo procurou identificar e analisar as oportunidades de diagnóstico precoce para neoplasias malignas de mama, disponíveis para as mulheres do município de Botucatu. MÉTODOS: Foram entrevistadas por telefone, segundo sorteio aleatório, 261 mulheres com idade de 30 anos ou mais. RESULTADOS: A média de idade foi de 51 anos e 49,45 por cento das entrevistadas apresentaram escolaridade de nove anos ou mais; 80 por cento receberam orientações gerais sobre prevençäo do câncer de mama e 86,9 por cento orientações específicas sobre autopalpaçäo; 78,9 por cento das mulheres realizaram o auto-exame das mamas e destas somente 27 por cento o fizeram corretamente. O exame clínico das mamas foi realizado em 76,2 por cento das entrevistadas e a mamografia em 35,6 por cento; se o exame de mamografia fosse solicitado por médicos e estivesse disponível, 83,1 por cento das mulheres estariam dispostas a realizá-lo. CONCLUSÄO: A prevalência e a mortalidade da doença säo maiores nas mulheres idosas. Neste estudo observou-se que estas apresentaram uma taxa menor de oportunidades de diagnóstico precoce, pois eram menos informadas sobre a periodicidade correta da autopalpaçäo e apresentaram uma menor freqüência de mamografia e de exame clínico das mamas do que as mais jovens. O grau de escolaridade mostrou também significância estatística, visto que as mulheres com mais anos de estudo tiveram melhores oportunidades do que as com pouco estudo
