Published: December 2015

El presente trabajo muestra un análisis orientado a la propuesta de diseño e implementación de un doble controlador en modo deslizante para un convertidor Buck CD-CA. Se plantean las superficies de deslizamiento candidatas de acuerdo con las exigencias de la aplicación y, mediante una lógica de activación de las llaves semiconductoras (MOSFET), se obtiene un control independiente en la amplitud de la tensión para el semiciclo positivo y negativo de la onda de salida en CA, con el objetivo de lograr a voluntad un nivel de CD introducido en la señal de alterna. Se ingresan perturbaciones de tensión en la entrada del convertidor y se producen variaciones en la carga con el objetivo de probar la robustez del sistema de control propuesto. El control se implementa en un microcontrolador AVR Atmega164PA y se prueba de manera práctica. Finalmente, se expone una comparación de los resultados obtenidos de manera experimental con las simulaciones realizadas en SCILAB5.

Published: December 2015

Introduction: This report reviews relevant literature on foreign bodies identified with cone‐beam computed tomography (CBCT) and documents a rare case of a foreign body that was serendipitously identified during routine implant treatment planning.Case Presentation: The literature shows a frequent occurrence of incidental findings with CBCT. This case documents incidental findings in the maxillary sinus and external auditory canal that were identified during routine CBCT used for implant treatment planning. The finding in the maxillary sinus was diagnosed as a mucous retention pseudocyst that did not require treatment. The finding in the external auditory canal was diagnosed as a foreign body (remnant of a cotton swab). Removal of the foreign body was prompted because of its presumed association with chronic headaches that were unresolved. Removal of the foreign body alleviated the chronic headaches, and implant placement proceeded uneventfully.Conclusions: This review and case underscore the importance of a thorough review of the entire tomographic image volume. Using advanced technology for treatment creates new responsibilities and places more liability on providers not to overlook findings that may be significant to the patient's health.

Published: December 2015

Background: This study aims to evaluate the effect of the distance between the alveolar crest of a full‐ceramic implant to the lowest point of the contact area of the crowns on the interdental papilla. Therefore, the authors proposed a new concept of linear measurements for the reproducible and metric evaluation of distances relevant for the assessment of hard and soft tissue changes around dental implants.Methods: A total of 216 sites were examined in 87 patients. In a radiographic and clinical evaluation, four relevant distances were evaluated. In the x‐ray image, the tip of the papilla was marked with a radiodense mixture of tungsten powder and temporary cement. In a clinical photograph, the lowest point of the interdental contact zone of the crowns was visualized by a metallic interdental ligature.Results: Using the proposed measuring methodology, four different papilla‐deficit situations around ceramic implants could be reproducibly distinguished. When the measurement from the bone crest at the implant was ≤5 mm, the papilla was completely present in 100% of cases. When this distance was 10 mm, the papilla was still present in 67% of the cases, without any cosmetically apparent deficit.Conclusions: A close relationship is observed between the distance from the contact point to the bone and the presence of the papilla. Using a combination of radiographically and clinically visible landmarks allows the reproducible measurement of these distances.

Authors: Pandey N K , Shrestha N , Karki P 
Published: December 2015

Background: The role of inflammation in the pathogenesis of acute coronary syndrome (ACS) is established, however use of inflammatory markers as predictors for future short-term cardiovascular events in patients of acute coronary syndrome. Objective: To assess whether inflammatory markers C-reactive protein (hs-CRP), total leucocyte count (TLC) and serum albumin can correlate with the diagnosis of ACS in patients with acute chest pain and to see whether these markers can be used to predict short-term cardiovascular events in patients of ACS. Methods: All Patients presenting within 12 hours of the onset of central non traumatic chest pain were enrolled and investigated, the diagnosis of ACS was made as per JACC 2004 guidelines for ST-elevation myocardial infarction, unstable angina and non-ST elevation myocardial infarction. All patients received routine institutional care and treatment as per diagnosis blinded to CRP, albumin, and total leucocyte count (TLC). The independent predictors of ACS and predictors of adverse events in 30 days was evaluated using multivariate analysis. Results: one forty nine patients of ≥ 18 years (88 male, 61 female) which were included in the study, the diagnosis of non-ischemic chest pain (NICP)were in 30 (20%) and ACS in 119 (80%) patients. TLC and hs-CRP levels were higher (11576±3083, 14.04±6.17) in patients with ACS compared to NICP (5596±1370, 2.39±1.55) with significant P-value (<0.001). Significantly high hs-CRP level (19.95±6.46), TLC (15630±3522) and low serum albumin (3.45±0.31) were there in patients in whom adverse cardiovascular events occurred. Conclusion: Leucocyte count and hs-CRP level are the independent predictors of ACS in patients presenting to the emergency department with chest pain suggestive of ACS. High hs-CRP, TLC, neutrophil count and low serum albumin, lymphocyte count are independent predictors of adverse short-term cardiovascular events.Health Renaissance 2014;12(2): pp: 99-105

Published: December 2015

Background: Pre-eclampsia /Eclampsia are becoming a leading cause of maternal and neonatal morbidity and mortality in developed and developing countries. Developing countries are at higher risk of facing this problem.Objective: To assess the maternal, fetal / newborn outcome of pre-eclampsia and eclampsia among mothers admitted in maternity ward of BPKIHS. Methods: This is a hospital based cross sectional study carried out in maternity ward at BPKIHS. A total 150 pregnant women (diagnosed of preeclampsia/eclampsia cases-75 and controls -75) included using purposive sampling technique. Data was collected using self-developed pretested, semi structured performa by the interview. Detailed physical examination and observations were also done. Results: Preterm delivery, early rupture of membrane, need for an assisted vaginal delivery (vacuum and forceps) and caesarean delivery, were significantly higher in cases than controls (P < 0.001). Abnormal range of fetal heart rate, still birth, intrauterine fetal death, birth asphyxia ,need for resuscitation, low birth weight and intrauterine growth retardation were significantly higher in cases than controls (P <0.001). Conclusion: Maternal, fetal and newborn outcome such as preterm delivery, caesarean section, birth asphyxia, low birth weight and intrauterine fetal death are more common seen among women who were diagnosed with preeclampsia /eclampsia than normal pregnancy. It is very important of early identification and prompt management to prevent complication of both mother and fetus.Health Renaissance 2014;12(2): pp: 106-110
Benign cystic lymphangioma of sigmoid mesocolon presenting as abdominal catastrophe: an extremely rare entity
Authors: Sah S , Nawal S , Gupta R , Kafle S 
Published: December 2015

Mesenteric cystic lymphangiomas (MCLs) are uncommon benign cystic tumours of unknown aetiology, most often seen in paediatric patients. The clinical presentation ranges from an incidentally discovered abdominal cyst to symptoms of acute abdomen. A10-year-old male presented with generalized abdominal pain, nausea and vomiting & constipation of several hours duration. Emergency laparotomy revealed multiple cystic masses along both the sides of sigmoid colon and mesocolon, which were inflammed mimicking diverticulosis. Sigmoidectomy with colorectal anastomosis was performed. The postoperative course was uncomplicated. MCLs should be included in the differential diagnosis of cystic intra-abdominal lesions. Even when asymptomatic and discovered incidentally, they must be treated surgically because of the potential to grow, invade vital structures and develop life-threatening complications.

La souffrance au travail
Authors: Foucart Jean 
Published: December 2015

La souffrance relève de l’insupportable. Les analyses en sociologie et en psychodynamique du travail opposent, dans une tentative d’explication, les facteurs macrosociaux à la dimension microsociale. Si souffrance au travail il y a, la question qui se pose est « pourquoi et comment ça tient ? ». Ne faut-il pas faire intervenir un troisième terme au niveau de l’explication ? Des concepts tels ceux d’espace intermédiaire ou de jeu prendront toute leur importance.
Pour une formation interprofessionnelle englobant la santé et les services sociaux. Quelques leçons du Royaume-Uni
Authors: Storrie Tom 
Published: December 2015

En raison de la complexification du monde professionnel, les champs d’expertise se démarquent les uns des autres et ils tendent à se cloisonner et à se hiérarchiser. C’est un moyen de contrôle des savoirs qui se renouvellent sans cesse ; il a pour effet d’interdire toute vision holistique. Les usagers des services médicaux et sociaux risquent de recevoir des soins spécialisés fournis par des professionnels entretenant peu de relations entre eux. Les systèmes de communication entre les différents secteurs et services dysfonctionnent souvent, avec des conséquences désastreuses. En dépit de multiples réformes bien intentionnées, des services formellement dédiés au maintien du bien-être des personnes et des populations sont incapables de se coordonner régulièrement et de répondre convenablement aux urgences des usagers. Une formation interprofessionnelle pourrait être un remède.
Création de soi et santé spirituelle : le rôle subtil des arts
Authors: Dallet Sylvie 
Published: December 2015

La santé est une expression fondamentale de la personne, tant du point de vue personnel qu’environnemental. La sophistication contemporaine des outils de la santé ne fait pas disparaître la métamorphose subtile appelée la création de soi. La médecine est un art qui puise sa vitalité aux racines du vivant : la création de soi est un exercice lent, spécifique à chacun ; elle se nourrit, comme une plante, des soins qu’elle reçoit et des obstacles qu’elle apprivoise. L’environnement ne fonctionne pas autrement : négligé ou violenté, il périclite et contamine dans son dépérissement les êtres qui le peuplent. La question de la santé interroge les philosophies de terrain et de respect de la différence. L’attention au malade favorise la guérison de la maladie, dans une dialectique qui fait intervenir le respect de la personne et la qualité des lieux qui l’accueillent.

Published: December 2015

L’épreuve(s) constitue un élément de l’expérience, mais à quelle(s) condition(s), notamment au regard de la Validation des acquis de l’expérience (VAE) ? L’intention est d’aborder la question des usages et du concept d’épreuve(s) autant que de la mise à l’épreuve(s) dans le champ de la VAE, afin de mettre en exergue la pluralité d’une utilisation caractéristique d’une mobilité conceptuelle. Dans une perspective épistémologique, l’épreuve est d’abord pensée quels que soient les contextes et les objets, puis elle est envisagée en prenant appui sur des faits et des réalités analysés en référence aux représentations, aux pratiques, aux postures, aux contextes relevant de la VAE.

AbstractPanel sequencing is a practical option in genetic diagnosis. Enrichment and library preparation steps are critical in the diagnostic setting. In order to test the value of HaloPlex technology in diagnosis, we designed a custom oncogenetic panel including 62 genes. The procedure was tested on a training set of 71 controls and then blindly validated on 48 consecutive hereditary breast/ovarian cancer (HBOC) patients tested negative for BRCA1/2 mutation. Libraries were sequenced on HiSeq2500 and data were analysed with our academic bioinformatics pipeline. Point mutations were detected using Varscan2, median size indels were detected using Pindel and large genomic rearrangements (LGR) were detected by DESeq. Proper coverage was obtained. However, highly variable read depth was observed within genes. Excluding pseudogene analysis, all point mutations were detected on the training set. All indels were also detected using Pindel. On the other hand, DESeq allowed LGR detection but with poor specificity, preventing its use in diagnostics. Mutations were detected in 8% of BRCA1/2-negative HBOC cases. HaloPlex technology appears to be an efficient and promising solution for gene panel diagnostics. Data analysis remains a major challenge and geneticists should enhance their bioinformatics knowledge in order to ensure good quality diagnostic results.

Authors: S Chetan , Seshadri H S , Lokesha V 
Published: December 2015

In the digital world of medical transcription involving various dimensions of processes, detecting the edge of a standard medical image for clinical research/diagnosis, telemedicine and other applicative purposes requires various efficient and effective methodologies to address the needs of the processes. Among these various meta-heuristics, as the size of the problem tends to increase along with time, the processes and their elemental techniques, proven to have been providing viable solutions appeals for reserve management and lesser computation times, with the efficiency of such algorithms and algorithmic operations to be enhanced at suitable levels of abstraction.
In this paper we propose an effective topological algorithm, which inhibits the characteristic features of high performance parallel enumeration in such heterogeneous computation environments. The proposed scheduler in the defined topological algorithm takes into consideration the metrics generated by As Built Critical Path (ABCP) - A hybrid methodological process. These metrics are re-initialized and processed to address the management of resources and the realization of search space. We also propose a methodology for shared memory access by the ants to perform parallel computation and as well implement the optimization factor in detecting the edge. An in-depth analysis with respect to the Speedup factor and the Execution time metrics are analyzed for various scenarios under consideration. The differentiations are evaluated and plotted for further futuristic analysis

Published: December 2015

The transmission of a suitably compressed image over a bandwidth, over long distances, gives rise towards a new era in the field of information technology. A gradual increase in this appending scenic application, involving the transfer of the images securely over the Ethernet has become an increasingly important aspect to be addressed during thou phenomenon, especially in the transfer of the digital medical images vividly, encapsulated with abundant information related to these images. The compressed medical images of the DICOM format contain certain amount of confidential data, pertaining to a clinical research or to an individual, and the confidentiality of the same has to be preserved from various security threats and eves-dropping. With a widespread applications among various multimedia applicative systems, telemedicine, medical imaging, military and certain safety-critical applications, inter-net and intra-net communicative applications, etc, a reliable transfer of suitable information, efficiently & securely is considered as one of the revolutionary aims in today’s communication technology and visual cryptographic methodologies. Real-time applications as such detailed above majorly is concerned with the security measures and many algorithms have been developed as a proof for various visual cryptographic methodologies.
In this paper we propose an efficient and a reliable visual cryptographic methodology which focuses on the encryption and decryption of the two-dimensional DICOM standard compressed medical image, effectively.
This paper discusses an efficient design of 192 bit encoder using AES Rijndael Algorithm with the decomposition of an image into square image size blocks and the image blocks are shuffled using 2D CAT map.
The shuffling of the image blocks/pixels employs a Logistic map of these image pixels coupled with 2D mapping of the pixels of the DICOM standard medical image, generated randomly, being the control parameter thereby creating a confusion between the cipher and the plain image, gradually increasing the resistive factor against the significant attacks. This paper proposes various analytical metrics such as correlation analysis,
entropy analysis, homogeneity analysis, energy analysis, contrast and mean of absolute deviation analysis, to evaluate the proposed algorithm, and their suitability in image encryption applications.
Application of the Cosine Gray Model Based on System Cloud in the Forecast of Higher Education Scale
Authors: Ge Chao , Li Cun 
Published: December 2015

The scale of higher education is an essential link in the process of the formulation of education planning and reasonable allocation of teaching resources. At the same time, it also provides the required basis and support for the government to formulate educational planning and policy. The scale of higher education development is influenced not only by the level of economic development and industrial structure, but also by the total population and the living standards of residents. We take these elements as the influence factors, which contain noise information. Because the scale of higher education and its impact factors have complex nonlinear relationship, the traditional forecasting method cannot describe their changing trends, which leads to the low accuracy of prediction. In order to solve the above problems, this paper bases on the traditional GM (1,1) model to judge the number of students in the future, and uses the weakening buffer operator to amend the historical data. Secondly, this paper analyzes the structure of the system cloud gray forecasting model, and demonstrates its integral generation principle. We propose a new method for the cosine gray forecasting model which is based on the system cloud SCOS-GM (1, 1), and prove the effectiveness of SCOS-GM (1, 1) model by the residual test.
Finally, the SCOS-GM (1, 1) model is utilized to predict the scale of higher education in China during the period of 2012-2014. The results show that the scale of higher education will demonstrate a gradual upward trend in the next few years.

Published: December 2015

Background Individuals with human T-cell lymphotrophic virus type-1 (HTLV-1)/HIV-1 coinfection have been demonstrated to undergo CD4+ lymphocytosis even in the face of immunodeficiency and increased vulnerability to opportunistic pathogens that can lead to poor prognosis. Objective This study investigated the prevalence as well as the effects of HIV-1/HTLV-1 coinfection on CD4+ cell counts, routine hematology, and biochemical parameters of study participants. Materials and Methods This prospective cross-sectional study involved 184 blood samples collected from HIV-1-seropositive individuals attending HIV-special clinic of the University of Abuja Teaching Hospital, Gwagwalada, Nigeria. These samples were analyzed for anti-HTLV-1/2 IgM antibodies using enzyme-linked immunosorbent assay, CD4+ cell counts, and some routine hematological and biochemical parameters. All samples were also tested for HTLV-1 provirus DNA using real-time polymerase chain reaction (PCR) assay. Results Of the 184 subjects studied, 9 (4.9%) were anti-HTLV-1/2 IgM seropositive; however, upon real-time PCR testing, 12 (6.5%) had detectable HTLV-1 provirus DNA. The CD4+ cell count was significantly high in HTLV-1-positive (742 ± 40.2) subjects compared to their HTLV-1-negative (380 ± 28.5) counterpart ( P-value = 0.025). However, there was no significant association between HTLV-1 positivity with other hematology and biochemical parameters studied ( P > 0.05). Conclusion All subjects (100%) who were HTLV-1/HIV-1-coinfected had normal CD4+ counts. This gives contrasting finding on the true extent of immunodeficiency of subjects. So it is suggested to be very careful in using only CD4+ counts to monitor disease progression and as indicators for antiretroviral therapy (ART) in resource-limited settings. In such conditions, there may be a need to test for HTLV-1 alongside HIV viral loads in order to begin appropriate ART regimens that contain both pathogens.
