Influencia de la enfermedad periodontal en el control metabólico de pacientes con diabetes mellitus tipo 2: revisión de la literatura

There may be an interaction between periodontal disease and sonic systemic diseases such as diabetes mellitus The objective of this review was to verify by means of a review of clinical trials if is a positive association between periodontal disease and the glycerine control of type 2 diabetes mellitus (DM 2) patients Eleven articles that fit the study criteria were revised It was concluded that periodontal disease may influence the metabolic control of 2 Additional studies with larger sample sizes and longer follow up are necessary for a better clarification of this issue (Rev Med Chile 2010 138 1172 1178)

Influencia de la actividad física en la enfermedad de Alzheimer: un caso clínico

Alzheimer's dementia (AD) is a neurodegenerative disorder that causes motor and cognitive decline. The aim of this study was to analyze the influence of a specific physical activity program on the cognitive, depressive symptoms and functional capacity of patients with diagnosis of probable AD. The subject, a 79-year old woman, participated in this program for three months, with 50 min sessions three times a week. The instruments used were the Cambridge Cognitive Examination; the Geriatric Depression Scale; and the Battery of the American Alliance for Health Physical Education, Recreation and Dance. The results in relationship with the depressive symptoms and functional capacity were significantly positive. There were no changes in regards to the patient's cognitive functions. In conclusion, this physical activity program seems to be an important part of the treatment for patients with AD, as it improves the functional capacity and also stimulates cognitive tasks. © 2008 Asociación Española de Fisioterapeutas.

El papel del óxido nítrico en la modulación del proceso inflamatorio de la enfermedad periodontal

Nitric oxide (NO) is a free radical with participation in almost all physiologic host processes; however, in high concentrations it may damage the tissues. Its immunoregulatory action is present in the inflammation and in auto-immune mechanisms, being intensively studied in the medical area. Recently, some studies have also reported that NO could play a role as etiopathogenic factor of the periodontal disease, which shows inflammatory and multifactorial course. Due to beneficial or damage effects of NO, according to its concentrations, some studies have been focused in the evaluation of inhibitor of NO-Synthase (NOS) as therapeutic agents in inflammatory processes. In this context, the aim of this study was to report the role of NO and NOS inhibition in the periodontal disease modulation process. In conclusion, it could be suggested that NO seems to play an essential role in evolution of inflammatory periodontal disease, and that the NOS inhibition may be considered as a promising therapeutic in modulation of inflammatory process.

O cuidador de paciente com neoplasia cerebral maligna primária: os desafios do cuidado

Patients with primary malignant brain tumor endure several motor and cognitive dysfunctions, demanding the presence of a caregiver even more because the time necessary for their assistance increases considerably. Usually this task is performed by a family relative, whose activities include taking care of the patient’s personal hygiene, escorting them to medical appointments, managing their money and performing their housework. All of this overwhelms the caregiver both physical and psychologically. This bibliographic research intends to analyze the role in which a caregiver plays in the quality of life of those kinds of patients, the complications of such task, the caregivers’ needs and the daily life of those terminal patients. It was used CAPES, PubMed and Google Academic databases for researching articles related to family caregivers who assisted adult patients with primary malignant brain tumor. The study concluded that being a caregiver of patients in such conditions harms one’s quality of life, with consequences such as stress, insomnia, financial problems and lack of social support. Theirs needs include: having someone to talk to about the matter, attending programs for reducing stress and increasing their knowledge about the disease. In advanced phases of the condition, the patient shows great mobility problems, aphasia and regular seizures, which end up overwhelming the caregiver. The level of quality of life found was above other types of cancer’s caregivers. Therefore, they represent a group with special needs, which should be especially handled by health professionals.

Cuidar de pacientes em fase terminal: a experiência de alunos de medicina

O objetivo deste estudo foi compreender os significados que alunos de medicina atribuem à experiência de cuidar de pacientes em fase terminal. Os dados foram coletados mediante entrevistas individuais com vinte e quatro estudantes de medicina de uma universidade paulista. As convergências dos depoimentos dos participantes foram agrupadas em três categorias: a) deparando-se com o mundo da doença terminal/morte; b) relação com o paciente e sua família; c) reflexão sobre o cuidar do paciente terminal. Nos depoimentos, os estudantes expressam ansiedade ao cuidar deste tipo de paciente, assim como as dificuldades em lidar com os próprios sentimentos. Consideram-se pouco preparados para relacionar-se com esses pacientes, mas aprenderam com a experiência vivida. Os resultados do estudo apontam para a necessidade de se introduzirem, na formação médica, conteúdos visando desenvolver competências interpessoais e capacidade de reflexão sobre questões de ética e deontologia médica, envolvendo a terminalidade da vida.

Vacinas contra Leishmaniose: uma revisão

Leishmania is a protozoan belonging to the family Trypanosomatidae, obligate intracellular parasite cells of the mononuclear phagocyte system. In the New and Old World several orders of wild mammals (natural reservoirs) and various species of sandflies (vectors) are involved in the transmission of leishmaniasis. The new settlements in rural areas, changes in the environment and unplanned urbanization increased human contact with vector and interaction with the animal reservoir. A simple prophylactic measure seems to be the vector control as well as disease reservoir. With the goal of raising the prophylactic measures that are being used in vector control, the reservoir of the disease and what the infrastructure accordingly. We conducted a literature review in July 2011 in the electronic databases of Bireme, Medline, CancerLit, Portal Capes, SciELO, PubMed and Medscape, the main texts on the subject. Thus, the development of a vaccine that is effective against various forms of leishmaniasis in the old and new world, it is necessary and has been recommended by WHO as a possible tool for effective eradication of the disease.

Prácticas culturales para el manejo de la Sigatoka negra en bananos y plátanos

Black sigatoka (Mycosphaerella fijiensis) control consists in the continuous use of fungicide sprays and cultural practices. Cultural control reduces inoculum sources of the pathogen and favorable environmental conditions for its development, as well as it increases the vigor of the plants. In order to manage the disease it is necessary to know its behavior through the time, its relationship with the weather and the crop management. The most important cultural practice to reduce the inoculum source is the removal of the whole affected leaves or only the diseased portions of the leaves. The removed tissue is placed over the ground and the use of urea is feasible to accelerate its decomposition. An alternative practice is the "mini-composting" that consists in forming small heaps with the dead leaves and harvested plants for its quick degradation, which allows to reduce the pathogen inoculum and to incorporate nutrients and organic matters into the soil. The early pruning of the tips of the Young leaves before they show symptoms of the disease and the quick elimination of harvested plants reduce the inoculum. Also, the agronomic management of the crop helps to reduce the favorable conditions and to increase the vigor of the plants: this management considers plantation density, drainage systems, irrigation methods, control of weeds, chemical-biological fertilization, and nematode control.
