Conocimiento de cáncer de mama y factores sociodemográficos, acceso y atención en salud en mujeres consultantes en centros oncológicos, Cartagena ­ Colombia / Conhecimento do câncer de mama e fatores sociodemográficos, acesso e cuidados de saúde em mulheres consultoras em centros de câncer, Cartagena ­ Colômbia / Knowledge of breast cancer and sociodemographic factors, access and health in women consultants in cancer centers, Cartagena ­ Colombia

Identificar los factores relacionados al conocimiento del estado actual de la enfermedad en mujeres con cáncer de mama y factores sociodemográficos, diagnóstico, tratamiento y atención del cáncer de mama en instituciones oncológicas, Cartagena-Colombia. Estudio descriptivo transversal; participaron 211 mujeres con cáncer de mama, mediante una encuesta estructurada. El Odd Ratio (OR) fueron calculados usando SPSS versión 23.0. Se encontró una asociación estadística entre la práctica del autoexamen de mama con el poseer estudios de educación superior y pertenecer al nivel contributivo; además, una mujer menor de 50 años con diagnostico confirmado de cáncer y que tenga un nivel educativo superior entró con una acción de tutela. Se identificaron lagunas derivadas de la estratificación social, segmentación geográfica y acceso a mecanismos de información telefónica. Por lo tanto, las condiciones de vulnerabilidad bajo nivel educativo y pobreza marcan diferencias y denotan oportunidades perdidas para la detección, atención y tratamiento.

Estudo descritivo transversal; 211 mulheres com câncer de mama participaram através de uma pesquisa estruturada. Foi encontrada uma associação estatística entre a prática do auto-exame das mamas e o fato de ter uma educação superior e pertencer ao nível contributivo; além disso, uma mulher com menos de 50 anos de idade com diagnóstico confirmado de câncer e com um nível de educação superior entrou com uma ação de tutela. São identificadas as lacunas derivadas da estratificação social, segmentação geográfica e acesso a mecanismos de informação telefônica. Portanto, as condições de vulnerabilidade, baixo nível educacional e pobreza marcam diferenças e denotam a perda de oportunidades de detecção, cuidado e tratamento.

To identify factors related to knowledge of the current state of the disease in women with breast cancer and sociodemographic factors, diagnosis, treatment and care of breast cancer in oncological institutions, Cartagena-Colombia. Cross-sectional descriptive study; 211 women with breast cancer participated through a structured survey. A statistical association was found between the practices of breast self-examination and having a higher education and belonging to the contributory level; in addition, a woman under 50 years old with a confirmed diagnosis of cancer and with a higher education level uses guardianship action by right. Gaps derived from social stratification, geographical, health system segmentation and access to telephone information mechanisms are identified. Therefore, the conditions of vulnerability, low educational level and poverty mark differences and denote lost opportunities for detection, care and treatment.

Does cone-beam CT alter treatment plans? Comparison of preoperative implant planning using panoramic versus cone-beam CT images

PURPOSE: The present study was performed to compare the planning of implant placement based on panoramic radiography (PAN) and cone-beam computed tomography (CBCT) images, and to study the impact of the image dataset on the treatment planning. MATERIALS AND METHODS: One hundred five partially edentulous patients (77 males, 28 females, mean age: 46 years, range: 26-67 years) seeking oral implant rehabilitation were referred for presurgical imaging. Imaging consisted of PAN and CBCT imaging. Four observers planned implant treatment based on the two-dimensional (2D) image datasets and at least one month later on the three-dimensional (3D) image dataset. Apart from presurgical diagnostic and dimensional measurement tasks, the observers needed to indicate the surgical confidence levels and assess the image quality in relation to the presurgical needs. RESULTS: All observers confirmed that both imaging modalities (PAN and CBCT) gave similar values when planning implant diameter. Also, the results showed no differences between both imaging modalities for the length of implants with an anterior location. However, significant differences were found in the length of implants with a posterior location. For implant dimensions, longer lengths of the implants were planned with PAN, as confirmed by two observers. CBCT provided images with improved scores for subjective image quality and surgical confidence levels. CONCLUSION: Within the limitations of this study, there was a trend toward PAN-based preoperative planning of implant placement leading towards the use of longer implants within the posterior jaw bone.

Ultrastructure of Proechinophthirus zumpti (Anoplura, Echinophthiriidae) by scanning electron microscopy

The ultrastructure of Proechinophthirus zumpti Werneck, 1955, mainly the external chorionic features of the egg, is described through electronic microscopy techniques. This species was first cited in Argentina, infesting Arctocephalus australis (Zimmermann, 1873). The morphological adaptations of adults and nymphs are described in both species of Proechinophthirus parasitic on Otariidae: P. fluctus (Ferris, 1916) and P. zumpti
