Evidencia actual sobre características demográficas en mastitis granulomatosa idiopática

Introducción: La mastitis granulomatosa idiopática es una enfermedad crónica benigna, rara y de etiología desconocida; tiende a confundirse con otras enfermedades debido a síntomas similares. Este estudio pretende identificar y cuantificar las características demográficas, los antecedentes ginecoobstétricos relevantes y las manifestaciones clínicas prediagnósticas de esta enfermedad Metodología: Se realizó una revisión sistemática con análisis agrupado de datos tipo meta análisis. Se utilizó una estrategia de búsqueda en PubMed. Todos los estudios relacionados con la definición, manifestaciones clínicas, diagnóstico, tratamiento y pronóstico de la mastitis granulomatosa idiopática fueron elegibles. Las variables de interés fueron edad, país, antecedente de contracepción hormonal, tiempo de evolución, tiempo desde el último embarazo, diagnóstico inicial, y manifestaciones clínicas previas a la consulta. No hubo restricción en fechas de publicación. Resultados: Fueron incluidas 641 mujeres con diagnóstico de MGI reportadas en 68 publicaciones que cumplieron los criterios de selección. La edad media fue 35.9 años, 14.1% de ellas estaba embarazada o lactando, el antecedente de consumo de anticonceptivos hormonales fue 21% y el tiempo promedio desde el último parto fue de 3.9 años. La afectación ocurre principalmente en mama izquierda y en cuadrante superoexterno. El cáncer de mama y el absceso mamario son diagnósticos diferenciales en la consulta. Discusión: El diagnóstico de MGI es un reto para el ginecólogo desde la consulta inicial. Debido a que sus manifestaciones clínicas no son específicas, su diagnóstico parece apuntar a la necesidad de un proceso de descarte de otras patologías más frecuentes e incluso de peor pronóstico. Palabras clave mastitis granulomatosa idiopática

Small-area variation in health care affecting the choice of cesarean delivery: the case of a Colombian health insurer

In the midst of health care reform, Colombia has succeeded in increasing health insurance coverage and the quality of health care. In spite of this, efficiency continues to be a matter of concern, and small-area variations in health care are one of the plausible causes of such inefficiencies. In order to understand this issue, we use individual data of all births from a Contributory-Regimen insurer in Colombia. We perform two different specifications of a multilevel logistic regression model. Our results reveal that hospitals account for 20% of variation on the probability of performing cesarean sections. Geographic area only explains 1/3 of the variance attributable to the hospital. Furthermore, some variables from both demand and supply sides are found to be also relevant on the probability of undergoing cesarean sections. This paper contributes to previous research by using a hierarchical model and by defining hospitals as cluster. Moreover, we also include clinical and supply induced demand variables.

Carcinoma de tiroides una verdadera pandemia?

El diagnóstico de cáncer de tiroides se ha incrementado y las posibilidades de detección de una enfermedad subclínica son altas, toda vez que disponemos de herramientas de detección más sensibles y de fácil acceso. Por ende, el clínico requiere conocer la historia natural del nódulo tiroideo y del carcinoma papilar de tiroides de bajo riesgo para brindar a su paciente el mejor tratamiento basado en la evidencia clínica. El objetivo de esta revision es reconocer los elementos clínicos que han condicionado el aumento inusitado de casos de cáncer de tiroides. Conclusión: El sobrediagnóstico del cáncer de tiroides es una realidad, que se posibilita por el uso extendido de biopsia por aspiración con aguja fina ((BACAF)) después de la detección de un nódulo tiroideo, en gran parte de manera incidental, sin acarrear la mayoría de las veces un mejor pronóstico después de su tratamiento.

Representaciones sociales de la medicina complementaria y alternativa (MCA) para el cáncer en estudiantes universitarios de carreras de ciencias de la salud

Se realizó un estudio cualitativo exploratorio con estudiantes de carreras de Ciencias de la Salud con el objetivo de comprender las representaciones sociales que tienen acerca de la Medicina Complementaria y Alternativa (MCA) para el cáncer. Se desarrollaron grupos focales y la información obtenida fue analizada a través del Análisis Temático e interpretada con base en la Teoría de las Representaciones Sociales. Se encontraron diversas representaciones sociales asociadas con la definición, los objetivos, los tratamientos, la eficacia, las fuentes de información y el origen de la MCA. En conclusión se evidenció una alta tendencia a la aceptación y a la manifestación de una actitud positiva, aunque ambivalente frente a la MCA, además de un desconocimiento por la diferenciación conceptual entre este tipo de Medicina y la Medicina Popular. La cultura y las creencias sociales predominan en las representaciones sociales que tienen los estudiantes de la MCA para el cáncer, pese a su formación académica.

Anestesia regional y periférica guiada por ultrasonido en el paciente critico

El presente trabajo es un capítulo de libro titulado “Anestesia Regional y Periférica Guiada por Ultrasonido en el Paciente Crítico” que será incluido en la última edición del libro “Manual de Ultrasonido en Terapia Intensiva y Emergencias” cuyo editor es el Doctor José de Jesús Rincón Salas y que será publicado por la Editorial Prado de México para distribución latinoamericana desde dicho país. Por solicitud del editor y teniendo en cuenta el enfoque del libro, el presente trabajo está dirigido a estudiantes de formación, médicos graduados y especialistas en las áreas de cuidado intensivo, anestesiología, dolor, medicina interna y medicina de urgencias. Tiene como propósito empapar de conocimientos necesarios y prácticos en anestesia regional a personas que usualmente no han tenido contacto con la anestesia regional, pues desafortunadamente sólo en los últimos años ha sido posible que la anestesia regional haya comenzado a salir de las salas de cirugía, ámbito donde ha estado confinada tradicionalmente. El lenguaje utilizado es sencillo y el capítulo ha sido escrito para que sea fácil de leer y consultar, dejando así mensajes muy claros sobre la utilidad, viabilidad e implicaciones que tiene el uso de anestesia regional guiada por ultrasonido en cuidado intensivo. Los autores esperamos que de esta manera, el presente capítulo permita continuar superando los obstáculos que se interponen entre los invaluables beneficios de la anestesia regional y los pacientes de cuidado intensivo que necesitan de ella.

Childhood obesity: should primary school children be routinely screened? A systematic review and discussion of the evidence

Background: Population monitoring has been introduced in UK primary schools in an effort to track the growing obesity epidemic. It has been argued that parents should be informed of their child's results, but is there evidence that moving from monitoring to screening would be effective? We describe what is known about the effectiveness of monitoring and screening for overweight and obesity in primary school children and highlight areas where evidence is lacking and research should be prioritised. Design: Systematic review with discussion of evidence gaps and future research. Data sources: Published and unpublished studies ( any language) from electronic databases ( inception to July 2005), clinical experts, Primary Care Trusts and Strategic Health Authorities, and reference lists of retrieved studies. Review methods: We included any study that evaluated measures of overweight and obesity as part of a population-level assessment and excluded studies whose primary outcome measure was prevalence. Results: There were no trials assessing the effectiveness of monitoring or screening for overweight and obesity. Studies focussed on the diagnostic accuracy of measurements. Information on the attitudes of children, parents and health professionals to monitoring was extremely sparse. Conclusions: Our review found a lack of data on the potential impact of population monitoring or screening for obesity and more research is indicated. Identification of effective weight reduction strategies for children and clarification of the role of preventative measures are priorities. It is difficult to see how screening to identify individual children can be justified without effective interventions.

Health surveys and use of maternal and child health care services in three municipalities within the Sao Paulo metropolitan area

Objectives. To describe the changes in the use of maternal and child health care services by residents of three municipalities-Embu, Itapecerica da Serra, and Taboao da Serra-in the Sao Paulo metropolitan area, 12 years after the implementation of the Unified Health System (SUS) in Brazil, and to analyze the potential of population-based health care surveys as sources of data to evaluate these changes. Methods. Two population-based, cross-sectional surveys were carried out in 1990 and 2002 in municipalities located within the Sao Paulo metropolitan area. For children under 1 year of age, the two periods were compared in terms of outpatient services utilization and hospital admission; for the mothers, the periods were compared in terms of prenatal care and deliveries. In both surveys, stratified and multiple-stage conglomerate sampling was employed, with standardization of interview questions. Results. The most important changes observed were regarding the location of services used for prenatal care, deliveries, and hospitalization of children less than 1 year of age. There was a significant increase in the use of services in the surrounding region or hometown, and decrease in the utilization of services in the city of Sao Paulo (in 1990, 80% of deliveries and almost all admissions for children less than 1 year versus 32% and 46%, respectively, in 2002). The use of primary care units and 24-hour walk-in clinics also increased. All these changes reflect care provided by public resources. In the private sector, there was a decrease in direct payments and payments through company-paid health insurance and an increase in payments through self-paid health insurance. Conclusions. The major changes observed in the second survey occurred simultaneous to the changes that resulted from the implementation of the SUS. Population-based health surveys are adequate for analyzing and comparing the utilization of health care services at different times.

What aspects of rehabilitation provision contribute to self-reported met needs for rehabilitation one year after stroke - amount, place, operator or timing?

BACKGROUND AND OBJECTIVE: To a large extent, people who have suffered a stroke report unmet needs for rehabilitation. The purpose of this study was to explore aspects of rehabilitation provision that potentially contribute to self-reported met needs for rehabilitation 12 months after stroke with consideration also to severity of stroke. METHODS: The participants (n = 173) received care at the stroke units at the Karolinska University Hospital, Sweden. Using a questionnaire, the dependent variable, self-reported met needs for rehabilitation, was collected at 12 months after stroke. The independent variables were four aspects of rehabilitation provision based on data retrieved from registers and structured according to four aspects: amount of rehabilitation, service level (day care rehabilitation, primary care rehabilitation and home-based rehabilitation), operator level (physiotherapist, occupational therapist, speech therapist) and time after stroke onset. Multivariate logistic regression analyses regarding the aspects of rehabilitation were performed for the participants who were divided into three groups based on stroke severity at onset. RESULTS: Participants with moderate/severe stroke who had seen a physiotherapist at least once during each of the 1st, 2nd and 3rd-4th quarters of the first year (OR 8.36, CI 1.40-49.88 P = 0.020) were more likely to report met rehabilitation needs. CONCLUSION: For people with moderate/severe stroke, continuity in rehabilitation (preferably physiotherapy) during the first year after stroke seems to be associated with self-reported met needs for rehabilitation.

Acolhimento na estratégia saúde da família:revisão integrativa

Objective. To review the literature regarding the application of the notion of user embracement and to identify the contributions of this concept for primary health care practices in Brazil.Method. We carried out an integrative review of the literature regarding primary health care. The following databases were searched: LILACS, SciELO, and MEDLINE, covering the period from 2006 to 2010. The following search terms were used in LILACS and SciELO: acolhimento and programa saude da familia and saude. For MEDLINE, the terms user embracement and family health program and health were used. The review was performed in November 2010.Results. We identified 21 articles meeting the inclusion criteria, all of which described studies carried out in Brazil. The articles were divided into three empirical categories: integration and embracement; primary care work process; and evaluation of services. These are complementary categories that converge to two main views of embracement: the first sees embracement as a means of reorganizing the primary health care environment, and the second sees embracement as an attitude towards users. The review also shows that embracement may be a management tool that supports the Unified Health System and is associated with the principles of comprehensiveness and universality.Conclusions. Embracement is able to create a bond between health care workers and users. It promotes self-care, a better understanding of disease, as well as user co-responsibility for treatment. In addition, it facilitates universal access, strengthens multiprofessional and intersectoral work, qualifies care, humanizes practices, and encourages actions to combat prejudice. Nevertheless, the perspective of health care users regarding embracement deserves more attention and should be the focus of future studies.

Production of nursing care in primary health care services

This descriptive and quantitative study aimed to characterize the production of nursing care in primary health care services in a region of the city of Ribeirao Preto, state of Sao Paulo, Brazil. The study sample comprised care actions delivered by nurses and registered in the HygiaWeb Information System, from 2006 to 2009. Statistical analysis was performed. Results showed that nursing care delivered by nurses accounted for 9.5 to 14.6% of total professional care provided by professionals. Eventual care actions were the most frequent. The concentration of programmatic care was higher for children, women, pregnant and postpartum women. In conclusion, the predominance of eventual care demonstrated that the health system has been focused on acute conditions. Little of nursing work has been directed at the achievement of comprehensiveness, considering the inexpressive share of longitudinal follow up in total care delivery. The expansion of nursing staff represents potential for care delivery to the population, but further qualification of nursing actions is needed.

The coordination of care for tuberculosis control

This descriptive epidemiological study analyzed the coordination of tuberculosis (TB) patient care in primary healthcare services according to 23 patients, 16 professionals, and 17 administrators from Ribeirao Preto, Sao Paulo, using an instrument adapted to evaluate TB. According to the informants, the coordination of healthcare provided to patients under the treatment of the Tuberculosis Control Program team was considered satisfactory; however, when there is a need to refer the patient to other care units there are weak points in the coordination of healthcare, which include: interruption of communication flow; and patients' incipient participation in the care process, with a need to increase the sense of responsibility for patient care and encourage patients to become active agents in the process.
