Bacillus calmette-guerin (BCG) lymphadenitis: Changing trends and management

Background: Bacillus Calmette-Guérin (BCG) vaccination is performed as a part of expanded Programme of Immunization (EPI). Suppurative lymphadenitis is the common complication of BCG vaccination. The optimum treatment for this complication is debated.Methods: All cases of BCG lymphadenitis presenting to pediatric surgical service over a 17-year study period were reviewed to determine the optimum treatment for this problem.Results: Sixty children were referred for the management of BCG lymphadenitis during the study period. Most patients (n=43) presented during 1988 and 1990. Children were healthy and received BCG (Pasteur strain) vaccination at EPI during first 2 months of life. Initially all the patients received medical treatment with anti-tuberculous drugs for one to nine months. Fifty-two children who presented with large (approximately 3cm) fluctuant lymph nodes, required a surgical procedure to avoid spontaneous rapture and sinus formation (Group A), whereas medical treatment was effective in five out of eight patients presenting with small (approximately 1 cm) nodes (Group B). Conclusions: Medical treatment with antituberculous drugs is not effective to treat BCG lymphadenitis, when the involved lymph nodes are around 3.0 cm and have developed fluctuation and inflammation of over lying skin

AN INVESTIGATIVE STUDY ON JOB SATISFACTION LEVEL OF EMPLOYEES WORKING IN SOFTWARE INDUSTRY, A VIEW POINT OF EMPLOYEES IN PAKISTAN

The study aimed to examine the role of working environment, pay and promotion, job security, level of fairness, relationship with coworkers and relationship with supervisor on the job satisfaction of the employees. Survey based data was collected from 183 respondents working in the software sector. Regression analysis was used to test the impact of the independent variables of the study on the job satisfaction. The results of the research revealed that there is a positive and significant relationship between working environment, pay and promotion, job security, and level of fairness and the job satisfaction. This implies that employees who are having good working environment, have reasonable and equitable pay and promotion, have higher job security, and are treated fairly, will have higher level of job satisfaction and these employees will contribute positively towards the success and overall productivity of the organization. Similarly, good and healthy relationship with coworkers and supervisor also leads to the job satisfaction. This implies that if employees coordinate well with each other and their supervisors they can have higher level of job satisfaction and they can contribute more towards the benefit of organization then the employees who do not coordinate well. In software sector if the management want to foster the job satisfaction of the employees they should provide good working environment, good pays and they should treat the employees fairly

Tricyclo­hexyl[2-(2,3-dimethyl­anilino)benzoato-κO]tin(IV)

In the title compound, [Sn(C6H11)3(C15H14NO2)], the SnIV atom adopts a distorted tetra­hedral SnOC3 arrangement. The dihedral angle between the benzene rings in the mefanamic acid mol­ecule is 82.16 (17)° and intra­molecular N—H⋯O and C—H⋯O hydrogen bonds help to establish the conformation. Two of the cyclo­hexyl rings are disordered over two sets of sites with equal occupancies

Depth Estimation and Image Restoration by Deep Learning from Defocused Images

Monocular depth estimation and image deblurring are two fundamental tasks in computer vision, given their crucial role in understanding 3D scenes. Performing any of them by relying on a single image is an ill-posed problem. The recent advances in the field of Deep Convolutional Neural Networks (DNNs) have revolutionized many tasks in computer vision, including depth estimation and image deblurring. When it comes to using defocused images, the depth estimation and the recovery of the All-in-Focus (Aif) image become related problems due to defocus physics. Despite this, most of the existing models treat them separately. There are, however, recent models that solve these problems simultaneously by concatenating two networks in a sequence to first estimate the depth or defocus map and then reconstruct the focused image based on it. We propose a DNN that solves the depth estimation and image deblurring in parallel. Our Two-headed Depth Estimation and Deblurring Network (2HDED:NET) extends a conventional Depth from Defocus (DFD) networks with a deblurring branch that shares the same encoder as the depth branch. The proposed method has been successfully tested on two benchmarks, one for indoor and the other for outdoor scenes: NYU-v2 and Make3D. Extensive experiments with 2HDED:NET on these benchmarks have demonstrated superior or close performances to those of the state-of-the-art models for depth estimation and image deblurring

Institutions of the ‘Belt & Road’ Initiative: A Systematic Literature Review

China is the second largest economy in the world. It has experienced tremendous economic growth in the history of development. Recently China is going through a period of slow economic growth. In 2013, it launched a large-scale global project-the Belt and Road Initiative. It is termed as ‘project of the century’. Almost 65 countries are assembled under the Initiative. There have been pertinent questions and much confusions with regard to the aims and structure of the Initiative. This article reviews some high-quality peer-reviewed works to find out the nature and goals of the Belt and Road Initiative. In doing so, we have followed the research methodology of systematic literature review. The institutional dynamics and aspects of the Initiative; such as, the Silk Road Fund, Asian Infrastructure Investment Bank, and the economics corridors are explained in the paper. The data reveal that trade and economic activities in the countries along the ‘Belt and Road’ Initiative are on the increase. The evidence presented in this study would facilitate to advance further research in the newly emerging field of the ‘Belt and Road’ Initiative.

Analysing and Modelling the Corrosion Behavior of Ni/Al2O3, Ni/SiC, Ni/ZrO2 and Ni/Graphene Nanocomposite Coatings

A study has been presented on the effects of intrinsic mechanical parameters, such as the surface stress, surface elastic modulus, surface porosity, permeability and grain size on the corrosion failure of nanocomposite coatings. A set of mechano-electrochemical equations was developed by combining the popular Butler-Volmer and Duhem expressions to analyse the direct influence of mechanical parameters on the electrochemical reactions in nanocomposite coatings. Nanocomposite coatings of Ni with Al2O3, SiC, ZrO2 and Graphene nanoparticles were studied as examples. The predictions showed that the corrosion rate of the nanocoatings increased with increasing grain size due to increase in surface stress, surface porosity and permeability of nanocoatings. A detailed experimental study was performed in which the nanocomposite coatings were subjected to an accelerated corrosion testing. The experimental results helped to develop and validate the equations by qualitative comparison between the experimental and predicted results showing good agreement between the two

Urolithiasis and psoas abscess in a 2-year-old boy with type 1 glycogen storage disease

We report on a pyogenic psoas abscess secondary to an impacted calcium oxalate ureteric stone in a 2-year-old boy with glycogen storage disease type 1 (GSD-1). The patient had a drainage of the abscess through a flank incision followed by percutaneous nephrostomy and open ureterolithotomy. Metabolic acidosis, hyperuricemia, hypocitraturia, and hypercalciuria appear to be significant in the pathogenesis of urolithiasis in patients with GSD-1. Regular ultrasonography of the abdomen along with optimal metabolic control may delay or prevent urolithiasis and its complications in GSD-1 patients
