Reis, Gilberto Marcos Dias dos;Guerra, Ana Cristina Silva;Ferreira, Joo Paulo Amaral;
Revista Brasileira de Cirurgia Plástica , 2011, DOI: 10.1590/S1983-51752011000400008
Abstract: background: hyperhidrosis is characterized by excessive sweating of the forehead, hands, feet, and armpits, either alone or in combination. it affects about 1% of the population. this study aimed to observe the effects of botulinum toxin in patients with hyperhidrosis and demonstrates the application technique of botulinum toxin, the areas of incidence of the disease, and the duration of the results. methods: a retrospective analysis of 39 patients with primary hyperhidrosis treated between july 2000 and july 2010 and followed up for 12 months was carried out. of these patients, 36% were male and 64% were female. patient ages ranged from 16 to 41 years. a total of 135 areas were treated. treatment consisted of intradermal injections of botulinum toxin. the total dose applied ranged from 37.5 u to 150 u, with an average dose of 75 u for each treated area. results: the therapeutic effect of botulinum toxin was observed from the third day after treatment, with a 50% reduction in symptoms within the first week of treatment and up to 94% reduction in the number of hyperhidrosis events after the second week. the reduction of symptoms lasted, on average, for 7 months. no cases of compensatory hyperhidrosis or mortality were observed. conclusions: the treatment of primary hyperhidrosis with type a botulinum toxin, although temporary, is an effective, safe, and minimally invasive treatment option. it has a high degree of satisfaction and allows patients to return to their professional activities on the same day. side effects and complications are temporary, infrequent, and regress without sequelae.

Abstract: introduction: the standard care for these lower extremity injuries with exposed bone is vascularized tissue transfer; however, this option is often not available or is technically difficult. the advent of dermal regeneration template, a bioengineered skin substitute, provides a remarkable alternative to the traditional reconstructive choices. cases report: the authors report two patients from a total of 246 patients who had burns involving their lower extremities, admitted to s. josé hospital burn unit, between january 2007 and december 2008. both patients had bilateral deep burn injuries with exposed bone affecting the anterior surface of lower leg and were treated with tangential excision of the burn eschar and placement of the dermal regeneration template. four weeks later, after engraftment of the matrix, the thin outer layer of silicone was removed and the epidermal coverage was restored with a split thin skin graft. stable wound cover was achieved and no further surgical procedures were required to maintain wound closure. conclusion: the use of a dermal replacement matrix expands reconstructive options for difficult burn (and non burn) wounds, preventing prolonged, staged procedures, allowing successful coverage of vital structures without the use of a flap and, as in these particular cases, the salvage of the extremity.

Objectives: This paper describes a technique to produce individualized X-ray positioning devices for intraoral digital imaging of dental implants with long-term stability. Materials and Methods: An X-ray positioning device was built for Gendex? Visualix? eHD sensor, using the Dentsply rinn XCP-DS? system individualized by the incorporation of the bite piece within an acrylic stent to perform successive standardized radiographs to 16 patients. X-ray tube stabilization was achieved with polivinylsiloxane. Series of 3 radiographs were taken to each patient in different moments. Specific linear measurements as the implant diameter (mesio-distal width) and the height between consecutive threads (thread pitch) were made to all radiographs to determine the reproducibility and accuracy of the procedure. Results: The intraclass correlation coefficient for the mesio-distal width was 0.964 [(0.920 - 0.986) 95% CI] (p < 0.01) and 0.990 [(0.976 - 0.996) 95% CI] (p < 0.01) for the thread pitch. Bland-Altman plots comparing implant diameter showed mean bias of 0.01 ± 0.01975, 0.01 ± 0.02243 and 0.0006 ± 0.025 for groups 1 - 2, 1 - 3 and 2 - 3 respectively. Mean bias of 0.0024 ± 0.00552, 0.0027 ± 0.00552 and 0.0003 ± 0.0012 was found for the thread pitch analysis of groups 1 - 2, 1 - 3 and 2 - 3. One sample t-test for trueness of mesio-distal width, thread pitch and ratio showed mean difference of 0.00156 mm for the test value of 3.3 (p = 0.9), -0.00026 mm for 0.8 (p = 0.96) and 0.0124 for 4.125 (p = 0.72), respectively, after the application of a magnification correction factor. Conclusion: The device produced reproducible images in different moments and was suitable for comparative clinical examinations of marginal

Abstract: this paper aims to add to the body of knowledge about the influence of the shareholder value on people management practices, with emphasis on the production environment. the paper begins with an overview of the origins and fundaments of finance and value generation concepts for company shareholders, with the main focus on the increase of share prices. an analysis is then made of the interface between these concepts and people management practices, exploring the bidirectional nature of this interface, since the human resources function is not only influenced by company guidelines but is also considered one of the main forms for helping disseminate it, in view of its role as an agent of change in company behavior. as such, the three main elements are examined, which, according to the literature, comprise this interface: variable compensation, performance management and work autonomy. lastly, a multiple case study is presented to verify how the financial concept of companies has been influencing these people management practices at the production level of companies operating in brazil, and to what extent these practices have contributed to disseminate the shareholder value mentality. the findings of this study indicate that, at the conceptual level, the influence of shareholder value on people management practices is indisputable, but that in practice its effect is still only minor, although changes in this direction are already occurring.

Abstract: the solid oxide fuel cell (sofc) is one of the most promising technologies for the production of electric energy, mainly due to the fact that it is virtually no pollutant. typically, the sofc is constituted of at least seven distinct phases: fuel, anode, electrolyte substrate (separating the two electrodes), cathode, air, and electrical interconnectors (two, completing the electrical circuit). thermodynamics clearly shows that electrochemical systems only can be reversible when homogeneous, what it is not case of the sofc, and therefore the application of equilibrium thermodynamics to these systems is incorrect. it is considered that the sofc can be better described by the reaction between adsorbed species. the efficiency then is calculated as the ratio between the free energy of this reaction to the combustion heat. estimates of thermodynamic parameters are developed for the global reaction, as well as adsorbed species reaction.

Abstract: in brazil, where 90% of the childbirths occur in hospitals, 67.1% of the cases of maternal death are due to direct obstetric causes, mainly hypertensive disorders, but a quarter of the deaths are due to indirect obstetric causes. as maternal death is a rare event, estimated in 76/100,000, the study of severe maternal morbidity, following international literature, can contribute to qualify obstetrical care. maternal morbidity is a continuum that ends with death, but there is a separate group, with extreme severity, known as near miss. from the literature review, there are the difficulties to obtain an operational definition of the cases of extremely severe morbidity or near miss. the prevalence ranged from 0.80-8.23%, according to the defining criteria and health care provided at the region. the characterization of severe maternal morbidity and near miss allows for monitoring the process of obstetrical care and could help to qualify treatment of maternal urgencies and emergencies, interrupting the process that can lead to death.

Abstract: objective: to compile, consolidate, and analyze information obtained in surveys conducted by the measure dhs [demographic and health surveys] program, concerning obstetric care and pregnancy complications for women in latin america and the caribbean, in the five years before the survey. methods: this exploratory study utilized data from demographic surveys carried out in the 1990s in seven countries of latin america: bolivia, brazil, colombia, the dominican republic, guatemala, nicaragua, and peru. the study describes the characteristics of the women who were interviewed and of the obstetric care that they received in the five years before the respective survey, and it also estimates the occurrence of prolonged labor and of hemorrhagic, hypertensive, and infectious complications in those five years. results: the median number of prenatal consultations ranged from 4.7 in bolivia to 6.6 in the dominican republic. more than 40% of deliveries in guatemala, peru, and bolivia were attended by traditional midwives, relatives, or other persons without formal training. the highest rates of deliveries performed in health care facilities (> 90%) were in the dominican republic and brazil. in guatemala, peru, and bolivia more than 45% of deliveries were at home. the highest rate of cesarean delivery was in brazil (36.4%), and the lowest rates (< 12%) were in peru and guatemala. the rate of pregnancy complications reported by the women surveyed was 16.7% in brazil, 17.9% in guatemala, 42.1% in colombia, 42.5% in nicaragua, 43.0% in the dominican republic, 51.7% in bolivia, and 51.8% in peru. conclusion: the reported occurrence of severe pregnancy complications in the surveys we examined was well above the 15% rate reported in other scientific literature, suggesting that these complications may have been overestimated in the measure dhs surveys. prior validation of the questionnaires used for data collection is extremely important in the generation of high-quality data.
