PREVALENCE AND FACTORS ASSOCIATED WITH THE PERFORMANCE OF MAMMOGRAPHY AND PAP SMEAR TEST

Objective: To estimate the prevalence and factors associated with the performance of mammography and pap smear test in women from the city of Maringá, Paraná. Methods: Population-based cross-sectional study conducted with 345 women aged over 20 years in the period from March 2011 to April 2012. An interview was carried out using a questionnaire proposed by the Ministry of Health, which addressed sociodemographic characteristics, risk factors for chronic noncommunicable diseases and issues related to mammographic and pap screening. Data were analyzed using bivariate analysis, crude analysis with odds ratio (OR) and chi-squared test using Epi Info 3.5.1 program; multivariate analysis using logistic regression was performed using the software Statistica 7.1, with a significance level of 5% and a confidence interval of 95%. Results: The mean age of the women was 52.19 (±5.27) years. The majority (56.5%) had from 0 to 8 years of education. Additionally, 84.6% (n=266) of the women underwent pap smear and 74.3% (n=169) underwent mammography. The lower performance of pap smear test was associated with women with 9-11 years of education (p=0.01), and the lower performance of mammography was associated with women without private health insurance (p<0.01). Conclusion: The coverage of mammography and pap smear test was satisfactory among the women from Maringá, Paraná. Low education level and women who depended on the public health system presented lower performance of mammography.

Torpedo sinuspersici Olfers, 1831

Electric rays, thought to be the most primitive of the skates and rays, have stout tails but have rather expansive disc. This group is distinguished by the presence of powerful electric organs, derived from branchial muscles in head region. Torpedo sinuspersici found inshore in sandy bottoms, and well offshore from the surf zone down to 200 m. Also on or near coral reefs (like Kish Island in Persian Gulf). Common in shallow sandy areas. Occasionally hooked by anglers, more often seen by divers; can deliver a strong shock. Flesh is edible. T. sinuspersici can survive for hours after being stranded on the beach. Little is known of the life history of the Gulf torpedo. It is a sluggish predator of bony fishes. At night it actively hunts for food, sculling slowly through the water about a meter above the bottom; during the day it usually rests on the bottom and opportunistically ambushes unwary prey. It uses its broad pectoral fins to envelop the target fish before delivering an electric shock to stun it. Usually solitary, they may form groups during the mating season. Reproduction is a placental viviparous, with the developing embryos initially surviving on their yolk sacs, and then on enriched uterine fluid produced by the mother. Litters of 9-22 young are birthed in the summer. Newborns measure about 10 cm wide; males mature at a disc width of 39 cm and females at 45 cm.

Added value of diffusion-weighted MRI in detection of cervical cancer recurrence compared with morphologic and dynamic contrast-enhanced MRI sequences

PURPOSE We aimed to evaluate the added value of diffusion-weighted imaging (DWI) to standard magnetic resonance imaging (MRI) for detecting post-treatment cervical cancer recurrence. The detection accuracy of T2-weighted (T2W) images was compared with that of T2W MRI combined with either dynamic contrast-enhanced (DCE) MRI or DWI. METHODS Thirty-eight women with clinically suspected uterine cervical cancer recurrence more than six months after treatment completion were examined with 1.5 Tesla MRI including T2W, DCE, and DWI sequences. Disease was confirmed histologically and correlated with MRI findings. The diagnostic performance of T2W imaging and its combination with either DCE or DWI were analyzed. Sensitivity, positive predictive value, and accuracy were calculated. RESULTS Thirty-six women had histologically proven recurrence. The accuracy for recurrence detection was 80% with T2W/DCE MRI and 92.1% with T2W/DWI. The addition of DCE sequences did not significantly improve the diagnostic ability of T2W imaging, and this sequence combination misclassified two patients as falsely positive and seven as falsely negative. The T2W/DWI combination revealed a positive predictive value of 100% and only three false negatives. CONCLUSION The addition of DWI to T2W sequences considerably improved the diagnostic ability of MRI. Our results support the inclusion of DWI in the initial MRI protocol for the detection of cervical cancer recurrence, leaving DCE sequences as an option for uncertain cases.

Do hereditary syndrome-related gynecologic cancers have any specific features?

Hereditary syndromes are responsible for 10 % of gynaecologic cancers, among which hereditary breastovarian cancer and hereditary non-polyposis colon cancer syndromes, known as HBOC and Lynch syndromes respectively, present the highest relative risk. The latter predisposes to endometrial cancer and both contribute to ovarian cancer. Cowden syndrome-related endometrial cancer and the increased risk of ovarian, uterine and cervical cancers associated with Peutz-Jeghers syndrome, are also demonstrated, while Li-Fraumeni syndrome patients are prone to develop ovarian and endometrial cancers. Despite these syndromes’ susceptibility to gynaecologic cancers being consensual, it is still not clear whether these tumours have any epidemiologic, clinical, pathologic or imaging specific features that could allow any of the intervening physicians to raise suspicion of a hereditary syndrome in patients without known genetic risk. Moreover, controversy exists regarding both screening and surveillance schemes. Our literature review provides an updated perspective on the evidence-based specific features of tumours related to each of these syndromes as well as on the most accepted screening and surveillance guidelines. In addition, some illustrative cases are presented.

Hydropic leiomyoma of the uterus presenting as a giant abdominal mass

We describe a case of a 35-year-old woman with a pedunculated uterine leiomyoma with diffuse hydropic degeneration presenting as a giant abdominal mass. The patient was admitted in the emergency department because of diffuse abdominal bloating and discomfort. Ultrasonography (US) showed a heterogeneous abdominopelvic mass. Magnetic resonance imaging (MRI) was performed to further characterise and revealed a myometrial pedunculated tumour. Despite its marked T2-signal heterogeneity and volume, there were no other suspicious findings to suggest a malignant nature; therefore, fertility-sparing myomectomy was performed. Leiomyomas frequently undergo degenerative changes altering their imaging appearances. Leiomyomas with uncommon degenerative changes may be difficult to differentiate from malignant myometrial tumours, based solely on imaging. To the best of our knowledge, a diffuse hydropic degeneration imaging appearance has only been described twice in the literature. We describe the imaging appearance of this rare form of leio

Pitfalls em radiologia ginecológica

Para o diagnóstico radiológico das patologias ginecológicas é essencial conhecer e compreender as indicações dos vários exames disponíveis e, para cada achado radiológico, integrar a idade, o contexto clínico e a história pregressa da doente. A Ressonância Magnética (RM) tem hoje um papel crucial no diagnóstico das doenças ginecológicas. Contudo, para maximizar o potencial desta técnica é imprescindível adequar o protocolo utilizado a cada caso e a cada doente e ter em conta algumas regras imprescindíveis à interpretação dos exames, que descreveremos neste artigo. A RM ginecológica é principalmente útil no estadiamento do carcinoma do colo do útero e do endométrio, podendo por vezes ser também útil na sua detecção, na avaliação da resposta ao tratamento, detecção da recidiva ou complicações e na avaliação de lesões anexiais de natureza indeterminada na ecografia. Nas doenças benignas é frequentemente usada na avaliação pré-terapêutica de leiomiomas uterinos, bem como na adenomiose e na endometriose. Em muitas destas situações há potenciais erros e pitfalls, para os quais o médico radiologista deve estar alerta, de forma a minimizar eventuais falhas diagnósticas ou erros de estadiamento.

Estratificação pré-terapêutica do carcinoma do endométrio por ressonância magnética - papel do estudo dinâmico após administração de contraste endovenoso e do estudo ponderado em difusão

O carcinoma do endométrio apresenta uma taxa de incidência em Portugal de cerca de 7.2%, sendo a 5ª neoplasia mais comum na mulher. Apesar de apresentar uma prevalência relativamente elevada, o seu prognóstico global é favorável, uma vez que 75% dos casos são diagnosticados em estádio precoce. O estudo por ressonância magnética é geralmente efectuado após a realização de uma ecografia para avaliação de uma hemorragia uterina anormal e após o diagnóstico histológico por histeroscopia ou ressecção. Contudo, a ressonância magnética pode apresentar um papel determinante no diagnóstico em casos de impossibilidade de biópsia e nos quais a biópsia é inconclusiva. Além do mais, apesar de esta técnica não ser contemplada na classificação para o estadiamento do carcinoma do endométrio da International Federation of Gynecology and Obstetrics de 2009, apresenta uma função fundamental no estadiamento pré-operatório destas doentes, sendo crucial para definir a abordagem cirúrgica e terapêutica. No presente artigo, as autoras descrevem o estado da arte da ressonância magnética funcional no diagnóstico e no estadiamento do carcinoma do endométrio, chamando a atenção para o papel do estudo dinâmico após administração de contraste endovenoso e do estudo ponderado em difusão nestes cenários através da revisão da literatura mais recente sobre este tópico.

Padrões de captação de constraste do útero TC e RM

Ao contrário da ecografia e da ressonância magnética (RM), a tomografia computadorizada (TC) não é uma técnica de primeira linha no estudo da patologia pélvica feminina. Contudo, a TC é frequentemente utilizada na avaliação de patologia pélvica não ginecológica, nomeadamente em contexto de urgência ou de seguimento, na qual os órgãos ginecológicos são englobados. Nestas situações, o padrão de captação de contraste endovenoso pelo corpo e colo do útero na TC pode ser de difícil interpretação e por vezes simular patologia, dado o amplo espectro de padrões de captação de contraste endovenoso, de variantes anatómicas e/ou de patologia subjacente. Neste artigo as autoras revêm e ilustram os padrões de captação de contraste endovenoso pelo útero em TC e RM e possíveis pitfalls, permitindo diferenciar os aspectos normais e patológicos do útero em TC.

Diagnostico de endometritis subclínica en vacas lecheras

Las enfermedades uterinas en el período posparto comprometen seriamente la eficiencia reproductiva. La clasificación hecha hace pocos años por Sheldon et al. (2006) permite diagnosticarlas con mayor facilidad de acuerdo al tiempo transcurrido desde el parto a su detección y diagnóstico. De acuerdo con esta clasificación ha sido posible utilizar las denominaciones de metritis puerperal a la que transcurre entre los días 4 a 10 posparto; a la endometritis clínica y la piómetra, que se observan a partir del día 14 posparto y la endometritis subclínica que ocurre en cualquier momento posterior a la culminación histológica de la involución uterina (en general más allá de las 5 a 6 semanas del posparto). En esta revisión se realiza un análisis de cada una de estas presentaciones y sus características. Finalmente se describen los tratamientos posibles que en su conjunto aún no han permitido una solución total quedando claro que es un control precoz y sobre todo durante el período de transición lo que permite disminuir el impacto de estas patologías sobre el tracto reproductivo y así mejorar la eficiencia reproductiva de la vaca lechera.

Evaluación de la involución, salud uterina y retorno de la actividad ovárica con la adición de zeolita 2% en la dieta basal de vacas lecheras

El objetivo de esta investigación fue evaluar el efecto de zeolita (Clinoptilolita) adicionado en la dieta basal de vacas lecheras durante 105 días, 60 días pre-parto (dap) y 45 días post-parto (dpp) y su influencia en la involución (IU) y salud uterina (SU), el retorno de la actividad ovárica (AO) y la condición corporal (CC). El proyecto se realizó en tres ganaderías de la comunidad de Soldados del Cantón Cuenca – Azuay, en 50 vacas secas, con una CC ≥ 3,5, entre 2 a 5 partos, clínicamente sanas y todas en las mismas condiciones sanitarias y de manejo; fueron divididas en un grupo control (n1=25), alimentadas con dieta basal y un experimental (n2=25), con dieta basal + 2% de Zeolita del consumo de materia (CMS). Se evaluó retorno de AO considerando folículos ≥ 10 mm de diámetro a los 15, 22, 35 y 45 dpp por Ultrasonografía transrectal, SU (>10 PMN) a los 35 dpp por cytobrush, IU considerando posición del útero con respecto a la pelvis (PU), simetría de los cuernos (SCU), y diámetro del cérvix (DC), a los 22 y 45 dpp por palpación rectal, y finalmente la CC a los 15 dap, parto y 45 dpp. Se usó un diseño completamente al azar (DCA) y los resultados fueron analizados con el programa estadístico SPSS versión 22.0, posteriormente fueron aplicados los estadísticos de “U de Mann Withney y Kruscall Wallis”. Se obtuvo eficacia en el GE con mayor porcentaje de vacas que retornaron su AO (respectivamente, para GC y GE fueron: 35 dpp 29,6% vs. 70,4%; 45 dpp 44,4% vs. 55,6%; p<0,05). La IU fue a los 45 dpp, los valores obtenido para GC y GE fueron: respectivamente, PU 40,0% vs. 76,0%, SCU 32,0% vs. 76,0% y DC 28,0% vs. 68,0%, (p<0,05). Y en SU también mostró eficacia en el GE obteniendo un 3,4% vs. 22,2% de PMN en comparación con el GC, (p<0,05). Finalmente, se comprobó diferencias significativas (p<0,05) en la CC al parto y 45 dpp con eficacia atribuida al GE. En conclusión, la adición de zeolita al 2% en la dieta basal mostró eficacia en la involución y salud uterina, retorno de la actividad ovárica y la condición corporal en vacas en transición, recomendando su uso en las ganaderías lecheras

Prevalência da infecção por HPV e perfil das mulheres frente ao exame de papanicolau no município de São José de Mipibú/RN.

The Human Papillomavirus (HPV) infection is the major sexually transmitted disease all over the world. There are many factors associated to infection and the virus persistency in the organism. This study aims to evaluate the women's knowledge, attitudes and practice about the Papanicolaou test (Pap), as well as analyze the HPV and Chlamydia trachomatis infections prevalences in sexually active women from the city of São José do Mipibu/RN/Brazil. This research was divided in two steps (step I and step II), using different methodologies and samples each. The samples collected in each step, even socio-demographic or from uterus cervix, are from different patients e were analyzed separated. In step I was evaluated 267 rural and urban zone women s knowledge, attitudes and practices about the Pap by home interview. In the step II were included 605 women with age ranged from 15 to 71 years old, with mean of 33,5 years old and from each one were collected two cervical samples, one for Pap and other for molecular biology, beside the epidemiological interview to investigate the correlation between prevalence of HPV infection and risk factors. To molecular analyses, the samples were processed using a mammal rapid DNA extraction technique protocol. For C. trachomatis DNA detection were used the CP24/27 primers, and GP5+/GP6+ to HPV. PCR products were analyzed by electrophoresis on 8% polyacrylamide gels, followed by silver staining. The results of the step I showed that, in spite of only 46,1% of the interviewed women they have demonstrated to possess appropriate knowledge on the Pap test, the attitude and practice proportions were significantly larger, 63,3% and 64,4% respectively. The largest education degree presented association with adaptation of the knowledge, attitudes and practice, while neglect, lack of solicitation of the exam for the doctor and shame, came as main barriers for the accomplishment of the exam. In the stage II the HPV general prevalence was 28,9%, being 26,7% in the women with normal cytology or benign alterations, 26,7% in the ones that had atypical squamous cells of undetermined significance (ASC-US) and 80% in those with Low grade squamous intraepithelial lesion (LSIL). the HPV infection prevalence was larger in the patients with up to 30 years of age and in the unmarried women, and those that had more than one sexual partner presented larger infection risk. The results show that the sexual relationship with multiple partners increased the infection risk for HPV and consequently the possibility of the occurrence of lesions uterine cervix
