A new method to evaluate glenoid erosion in instable shoulder

Background: We aimed to establish values and parameters using multislice reconstruction in axial computerized tomography (CT) in order to quantify the erosion of the glenoid cavity in cases of shoulder instability. Methods: We studied two groups using CT. Group I had normal subjects and Group II had patients with shoulder instability. We measured values of the vertical segment, the superior horizontal, medial and inferior segments, and also calculated the ratio of the horizontal superior and inferior segments of the glenoid cavity in both normal subjects and those with shoulder instability. These variables were recorded during arthroscopy for cases with shoulder instability. Results: The mean values were 40.87 mm, 17.86 mm, 26.50 mm, 22.86 mm and 0.79 for vertical segment, the superior horizontal, medial and inferior segments, and the ratio between horizontal superior and inferior segments of the glenoid cavity respectively, in normal subjects. For subjects with unstable shoulders the mean values were 37.33 mm, 20.83 mm, 23.07 mm and 0.91 respectively. Arthroscopic measurements yielded an inferior segment value of 24.48 mm with a loss of 2.39 mm (17.57%). The ratio between the superior and inferior segments of the glenoid cavity was 0.79. This value can be used as a normative value for evaluating degree of erosion of the anterior border of the glenoid cavity. However, values found using CT should not be used on a comparative basis with values found during arthroscopy. Conclusions: Computerized tomographic measurements of the glenoid cavity yielded reliable values consistent with those in the literature.

Estudo de um método automatizado para o cálculo da profundidade de visualização dos equipamentos de ultrassonografia

Ultrasound is the term that describes the sound waves with higher frequencies than human hearing. Ultrasound used in medical diagnosis is a modality based on the use of sound energy and the acoustic properties of the various parts of the body to produce images of stationary and moving tissues. However, despite the ease of use and security that this modality offers for not using ionizing radiation, one should ensure the accuracy and optimum performance of the equipment, which results in precise diagnoses. To accomplish that, periodic quality control tests must be performed, which include: physical and mechanical inspection of the equipment, image uniformity, depth of penetration/visualization, accuracy of distances, axial and lateral resolution, dead zone and doppler sensitivity. This work intends to study a computerized method for calculating the depth of penetration of ultrasound, comparing it to the observerdependent method currently used. The images were collected during the quality control tests of ultrasound equipment. The results of the comparison between the visual and computerized methods were not conclusive for selecting the safest methodology for obtaining the depth of visualization

Testes de Controle de Qualidade em Sistema de Processamento Computadorizado FUJI

Computed Radiography (CR) is a term used to describe the system that electronically records a radiographic image. CR systems use receivers or IP (imaging plate) to capture the analog signals and then allow the readers to do the image processing and converted into digital information. With the increasing expansion of the CR for medical diagnostics it is necessary that these systems receive the same type of monitoring related to Quality Control and Acceptance to the conventional processing systems. The current legislation fails to specify the parameters and procedures to be tested, allowing that somehow, some equipment is not fully able to use in clinical routine. In this project we used the standard AAPM Report Number 93, which is already fully established outside the country and displays all test parameters in CR. From there were chosen three types of tests that were performed in a satisfactory sampling of IP´s. With this procedure it was possible to establish which of those IP's should be out of use, which reveals the important purpose of the study, demonstrating the need for Quality Control Testing and Acceptance in Computerized Radiography as soon as possible are included in the legislation regulator in the country

All topics presented will support the monograph's study objects, presenting the Brazilian DeMolay Order, focusing on the challenges faced by the management of the National Bureau 2011/2012, that through integrated actions of communication and relationships, especially the virtual environment, resulted in the growth participant's numbers in the activities proposed by the national administration

Tendências de normalização na tradução para o inglês da obra As Mulheres de Tijucopapa

The present essay aims at observing possible tendencies of normalization by the translator Irene Matthews in the translation to English from As mulheres de Tijucopapo, by Marilene Felinto. The methodology employed is that of corpus-based translation studies (proposed by BAKER, 1993, 1995, 1996, 2000; SCOTT’s study concerning normalization, 1998; and CAMARGO’s research studies, 2005, 2007), and that of corpus linguistics (BERBER SARDINHA’s studies, 2003, 2004). The investigation was carried out by means of a combination of semi-manual and computerized analyses using the computer software WordSmith Tools. Based on Scott (1998), we analyzed the translation of five words considered to be preferred by the author, as well as their co-text, in relation to three normalization features. The final results obtained in this study show that the translator Irene Matthews tends to use strategies that may be identified as features of normalization.

The illuminist discourse of the digital divide: a critic to the Post-Fordist Informatic Mundaneum from Knoxville, Tennessee

This article discusses the project of the Information Society and the discourses that undergo it, as part of a political and ideological conception universalized by those countries that created and dominate computer technology, which is in turn is aligned with the Post-Fordist industrial capitalist order and its emphasis on economic accumulation and consumerism. We explain how information technology creates routines and legitimate social orders, taking for analyzes the case of the Clinton-Gore policy in the United States, when the discourse of the computer society was associated with the development and social welfare. This association is revealed in the speech made by Clinton in the city of Knoxville in year 1996. There we see the beginnings of the concern about the Digital Divide as a new form of "social disease" that prevents the passage to a better world, focused on productivity, accumulation and consumption in information-dense societies. This generates a clash between the industrial-graph-centric world and the oral-pre-industrial communities, as a result of attempting to transplant the institutional forms of the developed West. We explain the pillars of the new computerized order, and how they replaced previous epic narratives creating techno-deterministic or techno-phobic discourses in prejudice of more critical approaches. We identify the effects such deterministic discourses that connote the association between the Information Society, welfare and development, questioning the urgency of deploying this system at global level without profound critical discussion, clear goals focused on the benefit of the human beings, and the open participation of the users of the system.

Is bone transplantation the gold standard for repair of alveolar bone defects?

New strategies to fulfill craniofacial bone defects have gained attention in recent years due to the morbidity of autologous bone graft harvesting. We aimed to evaluate the in vivo efficacy of bone tissue engineering strategy using mesenchymal stem cells associated with two matrices (bovine bone mineral and α-tricalcium phosphate), compared to an autologous bone transfer. A total of 28 adult, male, non-immunosuppressed Wistar rats underwent a critical-sized osseous defect of 5 mm diameter in the alveolar region. Animals were divided into five groups. Group 1 (n = 7) defects were repaired with autogenous bone grafts; Group 2 (n = 5) defects were repaired with bovine bone mineral free of cells; Group 3 (n = 5) defects were repaired with bovine bone mineral loaded with mesenchymal stem cells; Group 4 (n = 5) defects were repaired with α-tricalcium phosphate free of cells; and Group 5 (n = 6) defects were repaired with α-tricalcium phosphate loaded with mesenchymal stem cells. Groups 2-5 were compared to Group 1, the reference group. Healing response was evaluated by histomorphometry and computerized tomography. Histomorphometrically, Group 1 showed 60.27% ± 16.13% of bone in the defect. Groups 2 and 3 showed 23.02% ± 8.6% (p = 0.01) and 38.35% ± 19.59% (p = 0.06) of bone in the defect, respectively. Groups 4 and 5 showed 51.48% ± 11.7% (p = 0.30) and 61.80% ± 2.14% (p = 0.88) of bone in the defect, respectively. Animals whose bone defects were repaired with α-tricalcium phosphate and mesenchymal stem cells presented the highest bone volume filling the defects; both were not statistically different from autogenous bone.

Evaluation of silent period on masticatory cycles of different muscles in dentate oral contraceptives users and nonusers

The aim of this study was to evaluate the influence of oral contraceptive use on the silent period (SP) of anterior temporal and masseter muscles during the menstrual cycle. Totally, 28 women on reproductive age were selected including 15 nonusers of any hormone and 13 contraceptive users. All patients were dentate without muscular temporomandibular disorders. Electromyography (SP test) of the anterior temporal and masseter muscles was conducted every week during three consecutive menstrual cycles at 1(st) day of menstruation (P1), 7(th) day (P2), 14(th) day (P3) and 21(st) day (P4). The SP values in the anterior temporal and masseter muscles were measured at both sides. The SP values of the right side (13.49 ms) at P2 were significantly different compared to the left side (12.28 ms). However, there was no significant difference on the interactions among the three factors. It can be concluded that the SP values in healthy women in reproductive age may not be influenced by the menstrual cycle with similar results for both muscles.

Análise Biomecânica em implantes com diferentes tipos de conexão: estudo pelo MEF-3D

The aim of this study was to evaluate the biomechanical behavior of different implant connection types, by means of three-dimensional finite element analysis. 3 Three-dimensional models were created with a graphic modeling software: SolidWorks 2006 and Rhinoceros 4.0, and InVesalius (CTI, São Paulo, Brasil), the bone was obtained by computerized tomography of a sagittal section of the molar region. The model was composed by bone block with an implant (4 x 10 mm) (Conexão Sistemas de Prótese, São Paulo), with different implant connections: external hex, internal hex and Morse-taper with the corresponding prosthetic component Ucla or Morse-taper abutment. The Three-dimensional models were transferred to finite element software Femap 10.0 (Siemens PLM Software Inc., CA, USA), to generate a mesh, boundary conditions and loading. An axial (200N) and oblique load (100N) was applied on the occlusal surface of the crowns. Analyses were performed using the finite element software NEiNastran 9.0 (Noran Engineering, Inc., USA) and transferred to the Femap 10.0 to obtain the results; after the results were visualized using von Mises stress maps and Maximum stress principal. The results showed the stress distribution was similar between models, with a little superiority of Morse-taper connection. It was concluded that: the three connection types were biomechanical viable; The Morse-taper connection presented the better internal stress distribution; there was not significant biomechanical differences on the bone.

Avaliações farmacoeconômicas em vigilância de medicamentos

The study aimed to identify pharmacoeconomic studies in pharmacovigilance and to observe the economic outcomes in post-marketing surveillance. Therefore, a bibliographic survey was performed in databases Lilacs, PubMed/ Bireme. The search strategy was done by using scientific health descriptors [ "adverse drug reaction reporting systems " OR " medication errors " OR "product surveillance, postmarketing" OR " sentinel surveillance" ] AND [ " cost-benefit analysis" OR "cost efficiency analysis " OR " costs and cost analysis " OR " hospital costs " OR " cost-effectiveness " OR " cost-effectiveness evaluation " OR " drug costs " ]. Manuscripts published in the last 10 years were selected. We chose 13 articles, of which 12 corresponded to cost-benefit analysis and only one to cost-effectiveness assessment. In only one study there was no economy, all the other ones generated savings, ranging from 13.7 to 30% in spending valued service. Surveillance actions were: continuing education; active search through tracking devices and / or implementation of round; teamwork and multidisciplinary deployment; computerized security services management, enabling traceability of information and alerts. The results of the proposed actions have led to the prevention of adverse drug reactions, to decline of risks to the patient, to the reduction of inappropriate prescriptions, as well as the length of hospital stay spending valued service.
