O objetivo deste estudo foi analisar os motivos que influenciaram um grupo de mulheres a nunca ter realizado o exame de Papanicolaou mesmo após iniciarem a atividade sexual. É uma pesquisa qualitativa. Utilizou-se a entrevista a partir da questão norteadora: Por que você nunca tinha realizado o exame preventivo anteriormente? A técnica da análise de conteúdo proposta por Bardin foi utilizada para a análise das descrições. As mulheres demonstraram desconhecimento do câncer, da técnica e da importância do preventivo. Revelaram ainda medo na realização e resultado do exame. A vergonha e o constrangimento foram sentimentos expressados por elas pela exposição da intimidade a que se submetem. Expressaram ainda possuírem valores culturais que dificultam mudança de atitude. O acesso ao serviço, ter emprego e filhos também foram relatados como impedimento. Os resultados mostram a importância de ações educativas sobre a necessidade do preventivo ao iniciar as atividades sexuais e desmistificar a técnica e resultado.

Seis cabras lactantes foram distribuídas aleatoriamente em um delineamento experimental em crossover, em dois grupos: sob condições termoneutras e estresse térmico. Um período de adaptação de 28 dias foi seguido por quatro períodos de 14 dias cada, quando os animais sob estresse térmico foram expostos à temperatura média de 33,84ºC; THI de 86,20; BGT de 36,18 e BT de 32,11ºC das 8 às 17 horas, incluindo radiação solar simulada das 10 às 15 horas. Não houve diferença entre as concentrações plasmáticas de progesterona, mas as fêmeas submetidas ao estresse térmico apresentaram diminuição nas concentrações plasmáticas de estradiol, quando comparados ao grupo termoneutro. A temperatura retal dos animais sob estresse térmico foi mais elevada quando foi comparada à do grupo de animais em condições de termoneutralidade. As cabras mantiveram as concentrações plasmáticas da progesterona, com diminuição na secreção de estradiol, quando expostas a um estresse repetido e intermitente, a despeito de ocorrer hipertermia durante o estresse pelo calor.

Forty-two mares were randomly assigned in a 3 x 2 factorial experiment which included three intervals between rectal palpation (6/6h, 12/12h and once a day palpation) and two frequencies of inseminations (daily or every other day). The mares were inseminated with semen from only one stallion, diluted in minimal contamination extender. There were no differences in the conception rate at first cycle, conception/cycle, conception total, efficiency of pregnancy in either system of rectal palpation, independently of the frequency of insemination utilized. Also there were no differences among intervals of rectal palpation concerning the following reproductive characteristics: number of cycles/mare, cycles/pregnant mare, cycles/ pregnancy, pregnancy/cycle, number of inseminations/mare, inseminations/ pregnant mare and insemination/open mare. There were no differences in pregnancy rate at first cycle, pregnancy rate/cycle, pregnancy rate total and efficiency of pregnancy between the two frequency of insemination. However, the frequency of insemination influenced the number of inseminations/mare, number of inseminations/ pregnant mare and inseminations/open mare. The highest values were observed with the mares inseminated daily. Therefore, insemination every other day can be recommended. If necessary the mare may be palpated rectally at intervals of six hours without reducing the pregnancy rate.

The cervical hypersensitivity tooth was analysed and treated by application of a varnish with high fluoride ions content (Duraphat) and of a glass ionomer cement usually indicated to cavity lining (XR-ionomer-Kerr). This technique was applied in sixty-seven teeth of Clinic Graduation patients (Faculdade de Odontologia de Araçatuba) and demonstrated a high index of satisfactory results. The clinical findings of this study relate that, this technique is more one method of choose by clinicians.

The effects of therapy in locally advanced breast cancer submitted to combined conventional telecobalt therapy plus chemotherapy with cyclophosphamide and 5-fluorouracil were studied in 49 patients. Associated to radical mastectomy in operable cases. Local tumor control was achieved in 86.7%. There were no local recurrences in those submitted to surgery but they reached 21.7% in inoperable patients who received only radiation therapy and chemotherapy. The median follow-up time for dead patients was 29.5 months and for living patients 79.3 months. The index of complete responses was 24.5% and the median disease free interval was 22.9 months. The overall survival rate, between three and five years, was 32.7%. Estrogen receptors were identified by using immunohistochemical assay ER-ICA and monoclonal antibody H222-SP gamma, Abbott. There were no differences in the complete response index, disease free interval and survival rates, among ER-positive and ER-negative patients, explained by the far advanced stage of the disease. ER-positivity was significantly correlated with histological features of the tumors: cell differentiation, presence of elastosis, absence of lymphocytic infiltration and absence of tumor necrosis.

PURPOSE: To assess the occurrence of metabolic syndrome (MetS) in postmenopausal breast cancer survivors. METHODS: A total of 158 breast cancer survivors were included in this cross-sectional study. Eligibility criteria were: women with amenorrhea >12 months and age ≥45 years, treated for breast cancer and no metastasis for at least five years. Clinical history and anthropometric indicator data (body mass index (BMI), and waist circumference, (WC) were collected. Biochemical parameters, including total cholesterol, HDL, LDL, triglycerides (TG), glucose and C-reactive protein (CRP), were measured. MetS was diagnosed as the presence of at least three of the following diagnostic criteria: WC>88 cm, blood pressure≥130/85 mmHg, triglycerides≥150 mg/dl, HDL <50 mg/dL,and glucose≥100 mg/dL. The Student's t-test and χ 2 test were used for statistical analysis. RESULTS: The mean age of breast cancer survivors was 63.1±8.6 years, with a mean follow-up of 9.1±4.0 years. MetS was diagnosed in 48.1% (76/158) and the most prevalent diagnostic criterion was abdominal obesity (WC>88 cm), affecting 54.4% (86/158) of the women. The patients without MetS had a longer follow-up compared those with MetS (p<0.05). Regarding the current BMI, PN average, those without MetS were overweight, and those with MetS were obese (p<0.05). Among the latter, comparison of BMI at the time of cancer diagnosis and current BMI (27.8±5.4 versus 33.4±5.4 kg/m2) showed a significant weight gain (p<0.05). Mean CRP values were higher in women with MetS (p<0.05). In the comparison of tumor characteristics and cancer treatments there was no difference between groups (p>0.05). CONCLUSION: Postmenopausal breast cancer survivors had a higher risk of developing metabolic syndrome and central obesity.
