O objetivo deste estudo foi avaliar a presença de C. dubliniensis dentre isolados bucais de pacientes com Diabetes mellitus do tipo I (n=39) e II (n=36), hansenianos (n=38) e sob quimioterapia para o câncer de mama (n=30) e de respectivos indivíduos controle pareados quanto à idade, gênero e condições bucais. Um total de 479 isolados previamente identificados por testes fenotípicos (formação de tubo germinativo, produção de hifas/pseudohifas/clamidoconídeos, fermentação e assimilação de carboidratos) e identificadas como C. albicans/C. dubliniensis foram incluídos no estudo. A existência de C. dubliniensis dentre os isolados foi analisada usando protocolo validado de PCR multiplex. Foi também realizado estudo de patogenicidade experimental utilizando camundongos em modelo de infecção sistêmica, objetivando comparar a virulência e cinética de infecção de C. dubliniensis com outras espécies do gênero Candida. Um isolado (0.002%) de C. dubliniensis foi detectado entre os isolados do grupo controle. Esta espécie não foi encontrada dentre os isolados dos outros grupos de pacientes. C. dubliniensis foi menos virulenta para camundongos em relação a C. albicans e C. tropicalis e mais virulenta do que C. krusei. O estudo da cinética de infecção mostrou infecção persistente no rim e no fígado mesmo após 21 dias da inoculação de C. dubliniensis. Conclui-se que a detecção de C. dubliniensis dentre os isolados clínicos foi baixa e observada apenas no grupo controle. C. dubliniensis foi menos virulenta para camundongos que C. albicans e C. tropicalis e causou infecção prolongada no rim e no fígado

The hearts of 30 dogs naturally infected with Leishmania infantum chagasi were evaluated histologically and immunohistochemically. Myocardial lesions were detected in all dogs, including lymphoplasmacytic myocarditis (27/30), myonecrosis (24/30), increased interstitial collagen (22/30), lepromatous-type granulomatous myocarditis (7/30), fibrinoid vascular change (3/30), and vasculitis (1/30). The parasite was detected in the hearts of 20 of 30 dogs. The number of parasitized cells correlated with the intensity of the inflammation and with the number of granulomas. The results indicate that cardiac lesions are prevalent in dogs with naturally occurring leishmaniasis even in the absence of clinical signs of cardiac disease.

The book features profiles in which are told histories of people who, because of having leprosy, have had experienced periods of great prejudice. Even in the 80s, there were still cases of compulsory hospitalization of patients. In other words, people were forced to withdraw from society because they had Hansen's disease. The narrative of the personal histories, at the book, is broken by explanations regarding to the disease and by the development of important aspects concerning the historical theme

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

Objective: This study aimed to understand how patients with Hansen's Disease perceive self-care from the complexity perspective. Methods: Qualitative, descriptive and exploratory study based on the Collective Subject Discourse. Results: Sample composed of 15 subjects, most of whom were married males (66.6%) with a mean age of 52.3 years and were classified in the polarized forms of the disease. The following themes emerged from the DCS synthesis: having Hansen's Disease, drug therapy, self-care and lifestyle. The study provided visibility to the vertical model, which is largely hegemonic in the tradition of public health care policies, showing concern about only treating the disease, disregarding the complex relationships involved. Conclusion: Acknowledging these limitations and setting strategies to change them in favor of the dialogue among interprofessional team members are challenges to further develop self-care practices and to empower patients in relation to treatment and disease.
