Comparative Study between Lidocaine 2% and Dexamethasone Local Wound Infiltration Effect on Postoperative Pain Post Mastectomy: A Randomized Controlled Study  [PDF]
Hussein O. Soliman
Advances in Breast Cancer Research (ABCR) , 2018, DOI: 10.4236/abcr.2018.74015
Abstract: Objective: To compare the efficacy and safety of Lidocaine 2% versus Dexamethasone injected locally in mastectomy wound as pain relieving agents. Materials & Methods: A randomized single-blinded study in which 50 patients candidate for Mastectomy were included. Participants were equally randomized into two groups; Group A, in which patients received 10 ml Lidocaine 2% and Group B, in which patients received 16 mL Dexamethasone. In both groups, the drugs were given via local infiltration in the subcutaneous layer of the Mastectomy wound immediately after skin closure. Pain control was assessed post-operatively in the first 24 hours using the visual analogue scale (VAS) in addition the need for additional analgesia was recorded. Results: There was a statistically significant lower VAS score in group A (Lidocaine group) when compared to those in group B (Dexamethasone group) 1 h, 6 h, 12 h postoperatively with no significance 24 h postoperatively (36% vs 64% 1 h, 28% vs 64% 6 h, 30% vs 72% 12 h and, 80% vs 60% 24 h). This statistical significance was evident throughout the post-operative hours (1 h, 6 h, 12 h). Though local Lidocaine caused marked improvement of pain in bigger number of patients in group A than group B, yet it showed no statistical significance 24 h post-mastectomy. Furthermore, the number of participants that needed additional doses of analgesia lower in group A (48% vs 56%) in comparison to group B, but still showed no statistical

Materials Sciences and Applications (MSA) , 2014, DOI: 10.4236/msa.2014.53017

In the plasma electrolytic oxidation (PEO) coating of light metal alloys, changing the electrical parameters and electrolytic composition can change the discharge behaviour and, ultimately, the thickness, surface morphology and porosity of the coating. In the present study a combination of cathodic and anodic current pulses with suitable Ton and Toff periods were used to control the porosity and other structural defects of PEO coatings of an AM60B magnesium alloy. In order to investigate the effect of a current mode on the plasma discharge behaviour and coating microstructure during the PEO treatment of magnesium alloy, the emission intensities of six different spectral lines from the plasma species were recorded simultaneously as a function of both time and current mode using optical emission spectroscopy (OES) system. The fluctuations in signal intensities and temperature during the coating process reflect differences in location of both the discharge initiation, and discharge type. The coating surface morphology and microstructure that are obtained can be linked to the plasma discharge behavior. These results are discussed in relation to the discharge behaviour, and how such changes in discharge behaviour relate to the coating mechanisms.

Protein Electrophoresis and DNA in Herbs Produced from Irradiated Ambrosia maritima Seeds Grown under Soil Salinity and Their Resistance to Insect
O.S. Hussein
American Journal of Plant Physiology , 2012,
Abstract: Damsisa (Ambrosia maritima L.) is one of the wild plants present in Egypt and different African countries of the Nile Valley. It considered as potential source of molluscicides for treatment of infected sites. In this study, DNA amplifications technique and protein electrophoresis were used for the evaluation of response of Damsisa herbs to gamma rays (γ-rays), soil salinity and their interaction on alleviation of salt stress. This study also examined the effect of herb as bio-resistant for insect infestation in Phaseolus beans. Protein electrophoresis revealed that the number of protein bands separated from plants grown in saline soil not changed either grown from irradiated or un-irradiated seeds except 40 Gray (Gy) dose. Meanwhile, it was observed that mixing Damsisa herb with infested Phaseolus beans reduced insect ability to lays eggs or complete life cycle. Also, it was found that herbs produced from irradiated seeds and grown in normal or in saline soil were more effective in destruction of Callosobruchus maculatus insect and decreased the loss from infested beans.
Determination of a space-dependent force function in the one-dimensional wave equation
S. O. Hussein,D. Lesnic
Mathematics , 2014,
Abstract: The determination of an unknown spacewice dependent force function acting on a vibrating string from over-specified Cauchy boundary data is investigated numerically using the boundary element method (BEM) combined with a regularized method of separating variables. This linear inverse problem is ill-posed since small errors in the input data cause large errors in the output force solution. Consequently, when the input data is contaminated with noise we use the Tikhonov regularization method in order to obtain a stable solution. The choice of the regularization parameter is based on the L-curve method. Numerical results show that the solution is accurate for exact data and stable for noisy data
Determination of forcing functions in the wave equation. Part I: the space-dependent case

Mathematics , 2014,
Abstract: We consider the inverse problem for the wave equation which consists of determining an unknown space-dependent force function acting on a vibrating structure from Cauchy boundary data. Since only boundary data are used as measurements, the study has importance and significance to non-intrusive and non-destructive testing of materials. This inverse force problem is linear, the solution is unique, but the problem is still ill-posed since, in general, the solution does not exist and, even if it exists, it does not depend continuously upon the input data. Numerically, the finite difference method combined with the Tikhonov regularization are employed in order to obtain a stable solution. Several orders of regularization are investigated. The choice of the regularization parameter is based on the L-curve method. Numerical results show that the solution is accurate for exact data and stable for noisy data. An extension to the case of multiple additive forces is also addressed. In a companion paper, in Part II, the time-dependent force identification will be undertaken.

Ninety six water samples were collected from eight wells in Al-jadriah district—Baghdad, from June 2010 to May 2011, and analyzed for presence of Fe, Mn, Zn, Cu, Co, Pb, Cd, and Nickel, using Atomic absorption method. Results revealed presence of only scanty amount of iron, Mn and Co, ranged from 0.09 - 0.29 ppm for iron and 0.016 - 0.339 ppm for Mn, and 0.01 - 0.732 ppm for Zn. Concentrations of other elements (Cu, Co, Pb, Cd, and Ni) were nil. All values were below the safe limit of water suitability for human uses, according to safe limits laid down by WHO (2011), Iraqi Measurement and Quality Control System and Iraqi Ministry of Environment. Wells’ water can be used under special management in Water management units.

Abstract: Background: Hepatocellular carcinoma is a great problem that poses a huge burden upon any healthcare system. In Egypt it has shown a doubling in its incidence rate. This study intended to assess the different prognostic factors for the overall survival of HCC patients in Egypt. Study Design: This is a retrospective patients’ charts review of all patients (561) admitted to the National Cancer Institute (NCI), Cairo University with HCC from January 2007 to December 2011. The main outcome measures were the median overall survival. Also, all demographics, clinicopathological variables, laboratory data were tested as prognostic factors for the overall survival. Results: The median overall survival of our patients was seven months. The overall actuarial probability of survival during the follow-up period was 65% of patients at six months, 25% of patients at 12 months, 11% of patients at 18 months, and only 3% of patients at 24 months. In our study, a broad range of clinical, laboratory, tumor parameters, and demographic data of patients had shown statistical significance in univariate analysis. However, when all these significant factors in the univariate analysis were further analyzed by stepwise multivariate regression analysis which revealed that only age less than 60, non-symptomatic cases, AFP less than 400, no PV thrombosis, no portal HTN, no ascites, no metastasis and potentially curative therapy were prognostic factors for the overall survival. Conclusion: Among all detected prognostic factors, only, management therapy is modifiable, other factors are non-modifiable. Thus, for HCC, the earlier the diagnosis and intervention, the better is the prognosis and outcome. Therefore, US screening and follow-up of high-risk groups are a must for early diagnose and better outcome.
