Percepção dos portadores de hanseníase acerca do auto cuidado

This study aimed at evaluating the perception of leprosy patients, the disease, with regard to its concept and self-care practice, as well as their knowledge concerning drug therapy. Fifteen patients participated in the study, of whom 11 were classified as multibacillary and 04 as paucibacillary. Semi-structure interviews containing six guiding questions were used for data collection, and the Collective Subject Discourse (CSD) was utilized as a theoretical framework. Analysis was performed based on the Theory of Complexity. It showed that patients suffer pain, a fact that is reflected on the need to change habits and prevent disability. It also showed that patients have doubts and feel insecure about treatment and prognosis, and that they are also the target of social prejudice even thought the term leprosy has been replaced by Hansen‟s disease. As regards self-care, the subjects showed lack of autonomy, limitations and subjection to instructions from health care professionals, who, according to the discourse that emerged, are mostly responsible for transmitting the knowledge concerning self-care practice. This fact can be explained by evidence of self-knowledge deficit by the the subjects. Concerning polychemotherapy treatment, which is recommended by the Ministry of Health, it was observed that the knowledge concerning its action and adverse effects is precarious. This information is provided during consultation; however, CSD showed that the subjects do not apprehend it. Therefore, health care professionals must instruct their clients not only as regards conventional treatment practices, but they must also help them to know themselves and to improve their critical judgment so that they can choose the best form of living after being diagnosed with the disease, thus guiding self-care by taking such choice into account

A proporção de plasma rico em plaquetas/enxerto ósseo autógeno pode influenciar o reparo ósseo de defeito de tamanho crítico: estudo radiográfico em calvária de ratos

Introduction: It has been suggested that bone grafts combined with platelet rich plasma (PRP) present greater density than bone grafts without PRP after healing process. However, this result may depend on proportion PRP/autogenous bone (AB) graft used. Objective: The purpose of this study was to analyze radiographically the influence of the proportion PRP/particulate autogenous bone (AB) graft on bone healing in surgically created criticalsize defects (CSD) in rat calvaria. Material and method: 50 rats were divided into 5 groups: C, AB, AB/PRP-50, AB/PRP-100 and AB/PRP-150. A 5 mm diameter CSD was created in the calvarium of each animal. In Group C the defect was filled by blood clot only. In Group AB the defect was filled with 0.01 mL of AB graft. In groups AB/ RP-50, AB/PRP-100 and AB/PRP-150 the defects were filled with 0.01 mL of AB graft combined with 50, 100 and 150 µL of PRP, respectively. All animals were euthanized at 30 days post-operative. Standardized radiographic images of the rat calvaria were obtained using Digora System (Soredex, Finland). The images were evaluated by three examiners using scores that indicated the percentage of radiopacity of the defect. The obtained data were subjected to statistical analysis (Kruskal-Wallis test, p < 0.05). Result: Group C presented radiopacity significantly lower than groups AB, AB/PRP-50, AB/PRP-100 and AB/PRP-150. Group AB/PRP-50 showed radiopacity significantly greater than groups AB/PRP-100 and AB. Conclusion: It can be concluded that the proportion PRP/AB graft influences bone healing in CSD in rat calvaria.
