[Beliefs about nursing in the Revista Brasileira de Enfermagem: reflections on ideals, science, and art].

The inquiry of this study is the beliefs related to the nursing professional in the first decades of this activity in Brazil. The investigation presupposes that some of these beliefs are still current. The objective is to point out the beliefs expressed by Revista Brasileira de Enfermagem (Brazilian Journal of Nursing) in 33 articles, during the period between 1932 (when the journal was created) and 1954. Five notions of the nursing professional were identified through the analyses of the symbology presented on the cover of the periodical--Egyptian mythology; ideal, science and art, inscribed in a triangle. The categories established for nurses were: self-forgetful, heroine, socially committed, mercenary and bad angel. Finally, the study proposes an interpretation to the ideas presented in the triangle.

Surface roughness of glass ionomer cements indicated for atraumatic restorative treatment (ART).

The purpose of this study was to evaluate the surface roughness of four conventional chemically cured glass ionomer cements (Fuji IX, Ketac Molar, Vidrion R and Vitromolar) commonly used in atraumatic restorative treatment (ART) immediately after material preparation. Twenty specimens of each glass ionomer cement were fabricated and surface roughness was measured after material setting. The specimens were further examined under scanning electron microscopy. Data were analyzed statistically by Kruskal-Wallis test and Mann-Whitney test at 5% significance level. Two-by-two comparisons showed statistically significant difference (p<0.05) between all materials, except for Ketac Molar and Vidrion R, which had statically similar results (p>0.05). Regarding their results of surface roughness, the materials can be presented in a crescent order, as follows: Ketac Molar < Vidrion R < Fuji IX < Vitromolar. In conclusion, from the tested glass ionomer cements, Fuji IX, Ketac Molar and Vidrion R presented acceptable surface roughness after setting reaction while Vitromolar showed remarkably higher surface roughness.

["In all homes, the moral comfort of science and of art": the Revista Nacional de Educação and scientific dissemination in Brazil (1932-34)].

Between 1932 and 1934, the journal Revista Nacional de Educação was published by Rio de Janeiro's National Museum, under the auspices of hte Brazilian Ministry of Education and Public Health and under the direction of Roquette-Pinto. Its main goal was to disseminate information on science, history, and art among a wide-ranging Brazilian public. The articles were written by the intellectuals of the day, many of whom were scientists at the Museu Nacional. The Revista also published translations of excerpts by a number of travelers. Every issue was published at a low cost, with a significant number of copies. The journal was touted as the initiative of a renewed Republic, part of a broader strategy of inaugurating new relations between government and a population to be educated. It defined itself as "a spiritual milestone in the Brazilian nationality" in tune with the ideal of a State whose educational initiatives were meant to constitute a people and a nation.

State of the art in oral and maxillofacial surgery: treatment of maxillary hypoplasia and anterior palatal and alveolar clefts.

As the new millennium approaches, it seems appropriate to look back at where we have been and where we are going with the care of patients with facial deformities. None of us can deny that although changes have been made, many current treatment modalities are no more than modifications of old techniques. We are, however, poised to make dramatic improvements in the management of facial abnormalities as we enter the new century and millennium. Biotechnology, genetic manipulation, and new surgical technology will become pervasive, and perhaps we will move from "modification" of the old into a completely new era of therapeutic approaches to the care of dentofacial deformities. "Opportunities multiply as they are seized" (from Sun Tzu), and the time of opportunity is approaching. This review will attempt to look at the state of the art in cleft care and in oral and maxillofacial surgery: where we have been and where we are going. It will be clear that there is overlap between specialties and that these overlaps will become greater as new regimens in the care of facial deformities come to the forefront.

Secondary cleft lip nasal reconstruction: state of the art.

OBJECTIVE: This paper summarizes the state of the art in secondary cleft lip nasal reconstruction, distilled from the many papers written on the subject and from the author's experience with many of those procedures over the past 25 years. METHODS: The evaluation starts with the skeletal base and the need for LeFort 1 or alveolar bone grafting is discussed. The boney dorsum is next evaluated and a "monobloc" osteotomy considered. The cartilaginous dorsum follows and a "spreader-strut" graft is entertained. The tip cartilages are approached with either an open Potter or Dibbell preferred or replacement conchal graft if the tip has been destroyed by previous surgery. The skin envelope is then adjusted using methods described by Tajima, Dibbell, and Bardach.

Nasopharyngeal CPAP: a nursing art.

CPAP, the use of continuous positive airway pressure as a means of providing respiratory support to the infant, has been studied since the early 1970s. A variety of delivery methods has been used. One method, that of providing CPAP through a single nasopharvngeal tube, is reviewed here. The process of delivering nasopharyngeal CPAP can be technically difficult, and requires careful attention to the infant and the CPAP system. The ability to anticipate and troubleshoot problems is essential. Done well, this process truly shows off the art of nursing.

Potentials of local health surveys: a state-of-the-art summary.

This paper provides a state-of-the-art summary of the potentials and limitations of local surveys for assessing health problems in local areas. The information they provide may be helpful for a variety of purposes such as measuring the need for services, planning programs to address these needs, and evaluating their impact. Particular advantages of surveys are that they: provide information on the needs of people who have not sought care; permit special studies of particular target groups; provide data on variables which are only available from "asking" people; enable information to be collected on a range of correlates and indicators of health care behavior; provide an opportunity for examining relationships among variables; and permit well-timed community estimates of the impact of experimental programs. Limitations include the validity and reliability of survey data, and the costs and other problems of survey implementation.

Treatment of stroke in older patients. A state of the art review.

The treatment of stroke in older patients is the rule rather than the exception in most parts of the world. Thus, an understanding of the effects of aging on pharmacological aspects of treatment, recovery and rehabilitation is very important. A considerable amount of work has now been completed looking for therapeutic interventions that might ameliorate the effects of stroke disease. Sadly, none has yet proved to be effective, but much is still awaited. In contrast, recent work has clarified the place of treatment in stroke prevention, particularly in hypertension and atrial fibrillation, which should help reduce the burden of stroke disease. In addition, it is now clear that well organised stroke care can dramatically reduce mortality and disability. The state of art in stroke treatment is now encapsulated in the multidisciplinary stroke unit and well coordinated hospital and community care.

Synthetic and natural polycations for gene therapy: state of the art and new perspectives.

Currently, the major drawback of gene therapy is the gene transfection rate. The two main types of vectors that are used in gene therapy are based on viral or non-viral gene delivery systems. There are several non-viral systems that can be used to transfer foreign genetic material into the human body. In order to do so, the DNA to be transferred must escape the processes that affect the disposition of macromolecules. These processes include the interaction with blood components, vascular endothelial cells and uptake by the reticuloendothelial system. Furthermore, the degradation of therapeutic DNA by serum nucleases is also a potential obstacle for functional delivery to the target cell. Cationic polymers have a great potential for DNA complexation and may be useful as non-viral vectors for gene therapy applications. The objective of this review was to address the state of the art in gene therapy using synthetic and natural polycations and the latest strategies to improve the efficiency of gene transfer into the cell.

Assessing the needs of the elderly: state of the art.

Need is a multi-faceted, multi-dimensional concept. National and international efforts to assess the needs of the elderly confront common problems: lack of an accepted definition of terms such as "needs," "want" and "demand;" perceptions which vary with age, professional role, relationship and time; a range of methodologies encompassing rational, empirical and relativistic approaches, as well as subjective, objective and statistical measures. Research instruments are being refined and shared, but the state of the art remains in its infancy. Use of index of incapacity measures appears to offer the best data base for planning needed services.

Reminiscing: the state of the art as a basis for practice.

This integrated review presents the state of the art in reminiscing and life review as derived from a review of the literature from 1960-1990. Reports, reviews, and research are categorized and critiqued with the purpose of clarifying the use of reminiscing for practice. Out of ninety-seven published articles describing reminiscing, only seven report negative outcomes; the remainder are either positive or nonevaluative. As a result, the author concludes that clinicians should use reminiscing in their practice, and researchers should continue to define the variables that lead to successful reminiscing.

Research synthesis: the state of the art.

The state of the art in research synthesis has advanced significantly in the last decade. Much of the improvement in research reviews is attributable to the application of rigorous scientific standards to the process of research synthesis. Three principal types of research syntheses are the narrative review, the replicated secondary analysis, and the meta-analysis or quantitative research synthesis. Each methodology has its strengths and weaknesses, but all have benefited from increased attention to procedural rigor. Modern methods for quantitative research synthesis have significant advantages in that they provide specific tests for the existence and consistency of relationships across studies.

Pancreatic disease: findings on state-of-the-art MR images.

Recent technical innovations have made MR imaging a useful technique for imaging the pancreas. The potential impact of MR imaging on the management and outcome of cases can be determined only by controlled prospective comparative studies; however, these cannot be performed adequately until the normal and abnormal appearances of the pancreas on state-of-the-art MR images are understood. This pictorial essay is presented to further this intermediate goal.

Livestock improvement: art, science, or industry?

The shift in perspectives about livestock improvement over a 70-yr period is reviewed. The view changes from livestock improvement as an art, through its becoming a science, to its application as a technology in industry. The use of scientific tools in corporate settings for poultry, dairy, and swine breeding usually involves a strong focus on the economics of production, and this focus determines that selection indexes should be used. Such focus has seemed to not have been present in breeding for the extensively managed species and livestock classes but seems needed in order to provide a basis for organization and direction of positive contributions of the breeding segment to the production segment.

The scientific basis of antenatal care. Report from a state-of-the-art conference.

The routine program for antenatal care consists of a number of scheduled visits aiming at detection of symptomless complications such as hypertension and deviation in fetal growth, as well as giving psychosocial support and health education. In a Swedish state-of-the-art conference in May 1990, the scientific basis of this routine program was critically evaluated. It was clearly demonstrated that the scientific evidence to support present timing and contents of routine visits is unsatisfactory, and that there is a great need for evaluation both of single diagnostic procedures and intervention and of programs of antenatal care. Evaluations of antenatal care should consider not only pregnancy outcome but also patient satisfaction and cost-benefit analysis. Long-term follow-up studies are urgently needed, not only of the effects of complications but also of antenatal diagnosis and interventions.

Assisted reproductive technology: the state of the ART.

At least one in ten couples of reproductive age is affected by infertility. Tubal disease, ovulatory defects, endometrosis and abnormal sperm physiology are the most common causes of failure to conceive. Many of these disorders can be treated successfully with surgery, ovulation induction or intrauterine insemination, but in selected cases, or where there is long-standing intractable infertility, assisted reproductive technology (ART) becomes the treatment of choice. We provide an overview of the techniques for assisted reproduction, including in vitro fertilization, gamete intrafallopian transfer and other related procedures. Indications for treatment, patient evaluation and advances in reproductive technology including embryo cryopreservation, micromanipulation and donor gametes are also reviewed.

Training and education in medical art.

Raising the standard of medical art was given impetus in 1959. Since then, modification and revision of the original scheme has taken place, leading to the development of comprehensive educational programmes that culminate in a postgraduate qualification that raises medical artists to the highest levels of professionalism.
