Knowledge and practice of women regarding cervical cancer in a primary health care unit

Objectives: evaluating the level of information about the examination of uterine cervical cancer and its association with sociodemographic variables in women of a health care unit in the city of Bauru, São Paulo, Brazil. Methods: we conducted a cross-sectional descriptive study with 370 women aged 25 to 59, through structured interviews in their own homes; we used descriptive statistics and the χ2 test. Results: 40.5% of the women had not undergone the Papanicolaou test at the recommended frequency; 58.2% incorrectly defined the test, and 69.5% did not know about the risk factors for the development of cervical cancer; the knowledge about the test showed statistically significant association with schooling and family income of the studied population. Conclusions: women present deficiencies on the proper practice of the Papanicolaou test, on knowledge about the test, risk factors and prevention methods. Therefore, it is necessary to develop primary health actions for the most vulnerable population.

Avaliação da instabilidade atlanto-axial em indivíduos com síndrome de Down por meio de radiografias da coluna cervical

O objetivo nesta pesquisa consiste em fazer um trabalho de prevenção junto às instituições APAE (Associação de Pais e Amigos de Excepcionais) e ASIN (Associação de síndrome de Down), ambas de São José dos Campos e ASPAD (Associação de Pais e Amigos de síndrome de Down) de Jacareí, orientando e avaliando sobre a presença ou não da instabilidade atlanto-axial (IAA), assim como verificar a prevalência dessa anormalidade nesses indivíduos. Foram convidados a participar do projeto todos os indivíduos das três instituições de assistência à SD, tendo formado uma amostra com 68 indivíduos, com idades entre 2 a 34 anos, sendo 39 do sexo masculino e 29 do feminino. Foram realizadas radiografias da coluna cervical nas posições de extensão, flexão e neutra, para as quais todos os responsáveis assinaram termo de consentimento. A verificação da IAA foi feita pela análise da distância atlanto-odontóide (DAO), utilizando o programa Radiocef, com uma ferramenta criada para isso. A DAO foi analisada nas três incidências, e era considerada a presença de IAA desde que o indivíduo apresentasse valores ?4,5mm em pelo menos uma dessas posições. Após a realização dos testes estatísticos e análise dos resultados, concluímos que a prevalência de IAA foi de 22,1% dos indivíduos, com valores DAO entre 4,5 e 8,83mm, tendo sido mais prevalente nos indivíduos do sexo masculino do que feminino, assim como nas crianças do que nos jovens e adultos. Foi possível verificar também que, a posição de flexão apresentou maior prevalência de IAA, mas que ela não deve sobrepor às posições de extensão e neutra, pois pode omitir casos ausentes em flexão, mas presentes nas outras posições. Dessa forma, foi realizado o trabalho de prevenção com a avaliação da IAA por meio da realização dos exames radiográficos em que os laudos... (Resumo completo, clicar acesso eletrônico abaixo)

Avaliação in vitro da adaptação cervical de coroas totais metálicas, variando os preparos dos términos cervicais, aliviando ou não as superfícies internas das coroas e empregando diferentes cimentos definitivos

Este trabalho avaliou a qualidade das adaptações cervicais de coroas totais metálicas, tendo como fonte de variação: a) o término do ombro cervical do preparo - biselado, inclinado em 1350; reto em 900, chanfro e gume de faca; b) o alívio ou não das superfícies internas das coroas; e, c) os tipos de agente de cimentação permanente, cimentos - fosfato de zinco Harvard; ionômero de vidro Ketac-Cem, policarboxilato de zinco Durelon e resinoso Panavia Ex. Inicialmente, foram confeccionados corpos-de-prova em modelos-padrão de aço inoxidável usinado, de acordo com o tipo de preparo dos términos cervicais experimentais. As cápsulas metálicas de aço inoxidável preparadas, tendo ou não alívio da superfície interna de 30 micrometros até a distância de 0,5 mm do limite do término cervical, justapunham-se precisamente e formavam um conjunto com adaptação e assentamento exatos. Estas foram cimentadas nos corpos-de-prova com os diferentes agentes cimentantes, os quais foram manipulados de acordo com as instruções dos fabricantes. Desenvolveram-se metodologias de reaproveitamento dos corpos-de-prova, estabilidade das cápsulas impedindo seu deslocamento durante a tomada das medidas e mensuração precisa. Concluiu-se que: a) as melhores médias de adaptações cervicais, semelhantes entre si, foram obtidas em modelos-padrão com ombros: lâmina de faca, ombro inclinado em 1350 e chanfro; b) as piores médias de adaptações cervicais, semelhantes entre si, foram obtidas em modelos-padrão com ombros reto em 900 e degrau em 900 com bisel de 450; c) houve melhora significativa na adaptação quando cápsulas metálicas foram cimentadas com alívio de sua superfície interna; d) os cimentos...(Resumo completo, clicar acesso eletrônico abaixo)

Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)

Determinants of baseline seroreactivity to human papillomavirus type 16 in the Ludwig-McGill cohort study

Background: Immunity plays an important role in controlling human papillomavirus (HPV) infection and associated lesions. Unlike infections caused by other viruses, natural HPV infection does not always result in a protective antibody response. Therefore, HPV antibodies are also considered markers of cumulative exposure. The aim of this study was to identify determinants of HPV16 seroreactivity at enrollment among women from the Ludwig-McGill cohort, a natural history study of HPV infection and risk of cervical neoplasia.Methods: HPV16 serology was assessed by ELISA for L1 and L2 capsid antigens, while HPV typing and viral load measurements were performed by PCR-based methods. The associations were analyzed by unconditional logistic regression.Results: Of 2049 subjects, 425 (20.7%) were strongly seropositive for HPV16. In multivariate analysis, seroreactivity was positively correlated with age, lifetime number of sexual partners, frequency of sex, and HPV16 viral load, and negatively associated with duration of smoking.Conclusions: HPV16 seroreactivity is determined by factors that reflect viral exposure.

Seven-Year Clinical Performance of Resin Composite Versus Resin-Modified Glass lonomer Restorations in Noncarious Cervical Lesions

Purpose: The purpose of this study was to comparatively assess the seven-year clinical performance of a one-bottle etch-and-rinse adhesive with resin composite (RC) and resin-modified glass ionomer (RMGI) restorations in noncarious cervical lesions.Methods and Materials: One operator placed 70 restorations (35 restorations in each group) in 30 patients under rubber dam isolation without mechanical preparation. The restorations were directly assessed by two independent examiners, using modified US Public Health Service criteria at baseline and 6, 12, 24, 60, and 84 months. The obtained data were tabulated and statistically analyzed using the Fisher and McNemar tests. A difference was significant if p<0.05.Results: Twenty patients were available for recall after seven years (66.6%), and 25 RC and 26 RMGI restorations out of 70 restorations were evaluated. Excellent agreement was registered for all criteria between examiners (kappa >= 0.85). Alfa and bravo scores were classified as clinically acceptable. The McNemar test detected significant differences within RC restorations between baseline and seven-year evaluations for anatomic form, marginal integrity, and retention (p<0.05). For RMGI restorations, a significant difference was identified for marginal integrity (p<0.05). As to material comparison, the Fisher exact showed a better retention performance for RMGI restorations than for RC restorations (p<0.05). Twelve composite restorations were dislodged (52.0% retention) and three ionomer restorations were lost (88.5% retention). The cumulative success rate for RC and RMGI was 30% and 58.1%, respectively.Conclusions: After seven years of service, the clinical performance of RMGI restorations was superior to that of the adhesive system/resin composite restorations in this study.

Cardiovascular and respiratory evaluation during cervical myelography using ioversol in dogs

The objective of this study was to evaluate cardiovascular and respiratory effects associated with neck flexion, subarachnoid puncture, cerebrospinal fluid drainage and the subarachnoid infusion of ioversol (320mgl/mL) in dogs under isoflurane general anesthesia. The dogs received infusion of: autologous cerebrospinal fluid at 38 degrees C (GC - control group); ioversol 0.3mL/ Kg at 25 degrees C (GI25) and heated to 38 degrees C (GI38). Heart rate, systolic and diastolic arterial pressure, respiratory rate, oxyhemoglobin saturation and electrocardiography readings were recorded. The results showed that cervical myelography with ioversol 320mgl/mL at 0.3mL/Kg (25 C-degrees and 38C degrees) did not significantly alter recorded parameters, except for an elevation in arterial pressure.

conventional radiography and computed tomography to cervical spine study of adult horses - review

The imaging is essential to aid the diagnosis of horses that have performance decrease associated with any pain or clinical signs related to the vertebral column. Radiography is the first imaging examination performed in these cases, particularly for disorders affecting the cervical region. However, this technique has limitations when the study of subtle changes due to the overlapping of adjacent structures. Computed tomography is a new diagnostic method in Brazil for the study of bone disorders in horses, but it is of great diagnostic value associate with the radiographic examination in order to provide an accurate assessment of the study area, owing to superiority in image quality when compared to conventional radiography. The aim of this study is increase and update knowledge of diagnostic imaging available to investigate cervical disorders in horses.

Collaboration of ultrasonography in the diagnosis of thyroid gland carcinoma in a dog - case report

The sonographic evaluation of thyroid glands in veterinary medicine presents challenges due to the complexity of the anatomical region, professional experience and type of ultrasonography equipment. The technique is considered a versatile diagnostic method that is noninvasive and has a low cost indicated in different clinical situations. Thyroid carcinoma is a malignant tumor that is often invasive and frequently metastatic to regional lymph nodes and lungs. The prognostic indicators for survival after surgery include tumor size, histological type, mobility and presence or absence of metastasis. The objective of the present report is to demonstrate the importance of ultrasound as a complementary method in the evaluation of thyroid carcinoma in dogs. At the Dr. Halim Atique Veterinary Hospital, an eight-year-old male Pit Bull was examined due to a history of firm painless swelling, approximately six inches in diameter, in the ventral cervical region, for about two months. The sonogram showed a nodular area, with defined and regular margins, and heterogeneous hypoechoic parenchyma, with areas of cavitation and swelling of the thyroid. Histopathology of the nodule was consistent with carcinoma. After thyreoidectomy and hormone replacemet, the patient is in good clinical condition.

Neoplasia mamária em cadelas: aspectos clínico-cirúrgicos

Oncology is presenting an important role in clinical practice as a speciality in recent years in Veterinary Medicine. Mammary gland tumors are detected mainly in old and middleaged bitches that are sexually intact or spayed and the caudal abdominal and inguinal mammary glands are the most affected and they present a percentage up to 75% of malignancy. The majority of dogs with mammary neoplasms are clinically healthy at the time of diagnosis and the tumors can be identified by the owner or a professional during a routine physical examination. Cytological examination of fine needle aspirates can be performed. This procedure is easy and low cost and some criteria that may indicate malignancy are evaluated, however to obtain a definitive diagnosis is performed histopathology of the excised tissue or from biopsy. Regional lymph nodes are the first lymph node to receive lymphatic drainage from the neoplasm. They are at the highest risk of regional metastasis, while the lung is the most common site for distant metastasis. Determining the clinical stage enables the definition of the extension of the tumor. As a consequence, this allows a prognosis to be established and treatment to be planned. The type of therapy to be chosen incites controversy since there are numerous treatment options described, but the surgery is the chosen treatment. However, surgery is not always effective for malignant tumors, and recurrences may occur and in these cases, auxiliary chemotherapy treatments are used. The prognosis for animals that have mammary tumors depends on several factors, such as: size, stage, type of tumor cells and clinical behavior of the tumor, age and medical condition of the animal, and presence of metastasis. Because of this, more detailed studies are needed based on epidemiological surveys in order to provide more informations about risk factors, prevalence and follow-up after treatment of mammary...

Espondilomielopatia cervical caudal em cães: diagnóstico por imagem

The Caudal Cervical Spondylomyelopathy, also known as “Wobbler syndrome” is a neurological disorder that affects mainly breeds of large and giant size, especially Doberman pinsher and Great danes. Its aetiology is multifactorial and leads to a narrowing of the spinal canal by morphological and positional caudal cervical vertebrae (C5, C6 and C7), causing compression of the spinal cord and nerve roots. The clinical signs presented by the affected animals are progressive ataxia of hindlimbs and, later, the forelimbs, sometimes progressing to tetraparesis. Neck pain may be present. The diagnosis is made through the association of clinical signs and diagnostic imaging such as radiography, myelography, computed tomography and magnetic resonance imaging. According to the classification of the lesion obtained by imaging examinations, the conservative or surgical treatment is established and the prognosis is variable in accordance with the degree of affection of the spinal cord

Atividade citotóxica e apoptótica de nitensidina A e B em células de carcinoma cervical imortalizadas pelo Papiloma Vírus Humano (HPV) e não infectadas

Câncer cervical é o segundo tipo mais comum em mulheres no mundo. Estudos apontam que a presença de certos tipos do HPV desempenha um papel central na formação do câncer. Apesar do grande sucesso da prevenção do câncer uterino com vacinas, o uso de produtos naturais para o tratamento de doenças é crescente e de grande importância econômica. Alcalóides guanidínicos isolados de Pterogyne nitens representam uma potencial fonte de novos tratamentos. O objetivo geral desse trabalho foi avaliar a atividade apoptótica induzida em células de carcinoma cervical infectadas (SiHa) e não infectadas pelo HPV (C33-A), tratadas com nitensidinas A e B, isoladas de folhas de Pterogyne nitens Tul. A citotoxicidade dos alcalóides foi avaliada utilizando o método de MTT. Para avaliar quantitativamente a apoptose e necrose celular, foi executado o ensaio de Anexina V por citometria de fluxo. Ambas as substâncias, nitensidinas A e B, apresentaram efeito citotóxico concentração-resposta em ambas as linhagens testadas (SiHa e C33A) e nos dois tempos de tratamento (24 horas e 48 horas). Não foi observada significância estatística quando comparados os perfis de ação citotóxica das duas substâncias em teste (nitensidinas A e B), em nenhuma das linhagens testadas (SiHa e C33A) e em nenhum dos dois tempos de tratamento (24 horas e 48 horas). Ambas as substâncias, nitensidina A e nitensidina B, apresentaram efeito indutor de apoptose precoce e, em menor número, de apoptose tardia/ necrose, em ambas as linhagens testadas (SiHa e C33A) e nos dois tempos de tratamento (24 horas e 48 horas)

Estudo in vitro da anatomia das projeções de esmalte cervical em dentes molares

The cervical enamel projection (CEP) is an anatomic variation that can be found in the cement enamel junction, it´s recognition and early diagnosis improves outcome the tooth involved, allowing greater efficiency in treatment. The knowledge of the location, grade and incidence of CEP is decisive on prevention and treatment of periodontal disease. It were studied 1200 molars (600 mandibular molars and 600 maxillary molars) separated from the collection of teeth on the Discipline of Anatomy in FOSJCampos - UNESP. Each group of 600 teeth was separated from the second side (300 teeth) and the second type (first, second or third molar). Each tooth had thoroughly inspected the cervical region, in all their faces, in order to verify the incidence and the grade of CEP in each surface. It was found that the CEP covered in 278 (23,17%) teeth was 146 (52,52%) mandibular molars and 132 (47,48%) maxillary molars. The CEPs were concentrated on a tooth surface in 222 (79,86%) teeth, in two surfaces 53 (19,06%) teeth, and in three surfaces in three (1,08%) teeth. From the total of 4.800 surfaces examined the CEPs were found in 337 surfaces, and 228 (67,66%) surfaces of the grade I, 60 (17,8%) grade II and 49 (14,54%) grade III. The buccal surface presented 207 (61,42%) CEP, the lingual surface in 57 (16,91%), the mesial surface in 35 (10,39%) and the distal surface in 38 (11,28%) CEP. The results of this study demonstrated that the CEPs have focused more on the mandibular teeth on only one surface of the tooth, the grade I was the most found and the buccal surface the most involved
