Prótesis radífera: Alternativa en el tratamiento de neoplasias de cabeza y cuello

Radipherpus protheses are a means of treatment for malignant tumor-carrying patients. These protheses are used in cases of brachytherapy or external actinotherapy by contact and allow treating them with high radiation doses that are quickly released from the areas next to tumor, so that the radiations be restricted to the affected region, without the emissions damaging or destroying the soft tissues. Based on these considerations, the present paper was aimed at making literature review on the use of radipherous protheses for the treatment of head and neck neoplasias. © 2006 1995, Editorial Ciencias médicas.

Evaluación del conocimiento de los cirujanos dentistas brasileños sobre aspectos bioéticos en el tratamiento odontológico

Professional-patient relationship and its importance for a good performance and success of the dental treatment must be reflected upon by means of their bioethical aspects. Our study aimed at evaluating dentist-surgeons' knowledge (n=163) in conducting specialization courses at São Paulo State University-UNESP, on these aspects. Out of the people surveyed, 88.1% mentioned that a decision for the treatment should be made by mutual agreement between professionals and patients, however, 26.4% report that patients' or their legal representative's participation in decision-making can cause negative interference. Professionals' acting when patients choose a less suitable treatment, 95.6% try to convince patients that it is not the best choice and persuade them for a better one by keeping the paternalistic model. It was noticed that 20.3% did not know how to relate the importance of professional-patient interaction as regards the dental treatment. It was therefore concluded that many dentist-surgeons are not taking these bioethical aspects into account in clinical practice.

El tratamiento fisioterapéutico ¿es efectivo en el mantenimiento físico y en la reducción del declive cognitivo de las demencias?

Introduction. Dementia is a chronic and neurodegenerative disease responsible for a progressive decline of cognition and physical capacity. Objective: To verify the effectiviness of three months of physiotherapy intervention on cognitive functions and balance of institutionilized elderly people with dementia. Patients and methods. This study has comprised thirty subjects, divided in two groups: EG (experimental group) and CG (control group). EG was composed by 15 participants with mean age of 71,6 ± 8,5 years and scholarity of 4,7 ± 4,2 years. CG was formed by 15 subjects with mean age of 78,5 ± 7,6 years and scholarity of 2,2 ± 1,8 years. The sample was evaluated by means of the following instruments: Mini-Mental State Examination, Semantic Verbal Fluency test, Clock Drawing test, Berg Balance Scale and Timed Get Up and Go test. The statistical procedures were done by means of Multivariate Analisis of Variance (MANOVA), with significance of 5 % (p < 0,05). Results. The results has shown a heterogeneity of both groups related to age (F = 0,2, p < 0,05) and scholarity (F = 2,6, p < 0,05). MANOVA pointed beneficts of physiotherapy on balance (F = 7,3, p < 0,01) but not on cognitive functions (F = 0,3, p > 0,05). Conclusions. Three months of physiotherapy were effective to improuve physical capacity of institucionilized elderly people with dementia. Neverthless, it was not able to minimize cognitive decline commonly seen on dementia. The question if a prolonged intervention could propitiate cognitive beneficts remains, specially in a more homogeneous groups.

Percepción del cirujano-dentista respecto del uso del consentimiento informado en el tratamiento odontológico

The objective of this study was to evaluate: the profile of the surgeon-dentist that undergoes a course in specialization at the Odontology Faculty of Aracatuba/UNESP, Brazil; if they requested informed consent from the patient and/or their legal representative before the realization of procedures, and if the treatment was decided upon with the patient. It was elaborated, validated and applied in questionnaire form, and the data obtained was analyzed by the program EPI-INFO 3.3 The conclusion was, given that surgeon-dentists still do not obtain any type of document before beginning treatment, a large percentage of them are totally vulnerable if submitted to ethical or legal prosecution and that it is necessary to be aware of this aspect.

Aplicabilidad del proceso de nitritación/desnitritación en el tratamiento de lixiviado de relleno sanitario

The biological nitritation/denitritation process in the removal of organic matter and nitrogen in a landfill leachate was studied, using an activated sludge sequencing batch reactor. Treatment cycles were formed by an anoxic and an aerobic phases, in which the conditions for oxidation of the influent N load and the prevalence of nitrite concentration at the end of aerobic treatment cycles were determined, as well as the use of organic matter present in the leachate as a carbon source for denitrifying organisms in the anoxic stage. The removal efficiencies of N-NO 2-at the end of the anoxic process (48h) ranged between 14 and 30%, indicating low availability of biodegradable organic matter in the leachate. As for the accumulation of N-NO 2-at the end of the aerobic phase (48h) of treatment cycles, imbalances were not observed, while 100% removal efficiencies of N and specific nitritation rates from 0.095 to 0.158kgN-NH 3/kgSSV per day were recorded, demonstrating the applicability of simplified nitrification in the treatment of effluents with low C/N ratios.

Bisphosphonates adherence for treatment of osteoporosis

Background: Osteoporosis is a disease of bone metabolism in which bisphosphonates (BPS) are the most common medications used in its treatment, whose main objective is to reduce the risk of fractures. The aim of this study was to conduct a systematic review on BPs adherence for treatment of osteoporosis. Methods. Systematic review of articles on BPs adherence for treatment of osteoporosis, indexed on MEDLINE (via PubMed) databases, from inception of databases until January 2013. Search terms were Adherence, Medication (MeSH term), Bisphosphonates (MeSH term), and Osteoporosis (MeSH term). Results: Of the 78 identified studies, 27 met the eligibility criteria. Identified studies covered a wide range of aspects regarding adherence and associated factors, adherence and fracture, adherence and BPs dosage. The studies are mostly observational, conducted with women over 45 years old, showing low rates of adherence to treatment. Several factors may influence adherence: socio-economic and cultural, participation of physicians when guidance is given to the patient, the use of bone turnover markers, and use of generic drugs. The monthly dosage is associated with greater adherence compared to weekly dosage. Conclusions: Considering the methodological differences between the studies, the results converge to show that adherence to treatment of osteoporosis with BPs is still inadequate. Further experimental studies are needed to evaluate the adherence and suggest new treatment options. © 2013 Vieira et al.; licensee BioMed Central Ltd.
