Published: November 2018

Background:Femoral shaft fractures are one of the most common fractures of the lower extremities in children. Although many approaches and options are available for their treatment, the most appropriate treatment option for school going children is still debatable.Objective:This study investigated the efficacy, safety, and outcome of surgical intervention with Elastic Stable Intramedullary Nailing (ESIN) in 3–12-year-old children with diaphyseal femoral fractures and compared them with those of conservative management.Methods:In this prospective study, 41 children with diaphyseal femoral fractures were recruited between April 2013 and April 2016. The fractures were divided into two equal groups: one treated with ESIN, and the other with early spica casting or noninvasive traction followed by hip spica casting. Demographic data, clinical information, and serial radiographic findings were collected and compared between the two groups. Flynn’s scoring criteria pertaining to time to union, assisted weight bearing, independent ambulation, return to school, and complications were applied. Fischer’s exact test was used for statistical analyses.Results:Compared with spica casting-treated fractures, ESIN-treated fractures healed faster with lower average time to assisted weight bearing, independent ambulation, and return to school. Hip spica-treated children had a higher rate of major complications than ESIN-treated children. At 1-year follow-up, higher limb length discrepancy was reported in hip spica-treated children than in ESIN-treated children (P< 0.001).Conclusion:ESIN is a safe and effective approach for treating femoral shaft fractures in children; it provides better functional and radiographic outcomes than spica casting and can be used in preschool-age children.

Published: November 2018

Introduction: Though the development of minimally invasive surgery has revolutionized the field of surgery, post-operative pain is still a significant issue. Unlike in the past, concerns about adverse effects have limited the role of opioids in post-operative pain management. This study aims to compare the effectiveness of intravenous paracetamol and diclofenac as postoperative analgesia in laparoscopic cholecystectomy.
Methods:One hundred and twenty eight patients of American Society of Anesthesiologists (ASA) categories I and II included in this study were divided into two groups. Anesthesia induction and maintenance were standardized. The first group received 15mg/kg (maximum 1gm) intravenous paracetamol and the second group received 2mg/kg (maximum 75mg) intravenous diclofenac 30 minutes prior to ending of surgery. A questionnaire was responded by patients and chart was maintained by visual analogue scale. Mann Whitney U test was used to analyze quantitative data and Chi-square test for categorical data. P value <0.05 was considered statistically significant.
Results: Profiles of hemodynamic changes were almost similar in both groups with respect to heart rate and blood pressure. However, paracetamol infusion provided hemodynamic stability in post-operative period. We observed statistically significant differences in visual analogue scale between the two groups. Most of the patients in paracetamol group had low mean pain scores in post-operative period and provided an extended analgesia compared to diclofenac. No serious postoperative complication was observed in paracetamol group.

Conclusion: Administration of intravenous paracetamol has better and prolonged analgesic effect with low mean pain score and less requirement for rescue analgesia compared to diclofenac.

Introduction.A number of researchers point at a direct connection between mutations of genes affecting the haemostasis system and risks of venous thromboembolism and / or infertility. Quite often, a thrombophilia diagnosis is a result of overdiagnosis, which may lead to ungrounded and even dangerous medical prescriptions. In this context, the key goal of this work was to analyse the homeostasis system in women with recurrent pregnancy loss and establishes the causes of this phenomenon.Materials and methods.Over the course of this work, we analysed 79 women in various stages of pregnancy who were receiving treatment in the Pregnancy Pathology Department of the BSMU Clinic. We analysed their medical histories, Body Mass Indexes (BMI), polymorphisms of haemostasis system genes and thrombosis risk factors.Results and discussion.BMI analysis found normal body mass in 39 patients (49.4 %) and excessive body mass in 40 patients (50.6 %). F2 and F5 gene polymorphisms were almost entirely absent. ITGA2 and ITGB3 gene mutations were found in the patients analysed in 48.1 % and 17.7 % of the cases, respectively. PAI-1 gene mutations were found in 84.8 % of cases. MTR and MTRR gene polymorphisms were detected in 35.4 % and 81.0 % of the patients, respectively. MTHFR mutations were found in more than 40 % of the patients.Conclusion.Obesity and hereditary thrombophilia are primary factors in venous thromboembolism. Body weight loss and antithrombotic therapy reduce risk obstetric complications, improving prognosis and pregnancy outcomes.

Purpose of the study:to analyse the results of organ-preserving operations in patients with localized renal cell carcinoma.Materials and methods. The results of treatment of 458 patients who underwent organ-preserving treatment for renal cell carcinoma between 2009 and 2017 were analysed and evaluated. Of these, 286 were men (62.4 %) and 172 were women (37.6 %) with an average age of 54.7 ± 2.25 years (between 23 and 84 years).Results. The size of the tumours ranged between two to eight centimetres (average tumour size 4.6 cm). The duration of “open” operations ranged from 30 to 110 minutes (average of 62 minutes); those using laparoscopy lasted between 85 and 180 minutes (average of 146 minutes). The volume of blood loss during the operation was an average of 133.6 ml (from 80 ml to 500 ml). In most patients, the tumour was in the first stage of the disease (443 cases, or 96.7 %). In 17 of patients operated on morphologically, invasion of paranephric fibre at the third stage (3.7 %) was detected. A further 8 patients had a second stage tumour more than 7 cm in size but without germination beyond the kidney (1.7 %). There were no cases of intra- or post-operative mortality. Discussion. No significant differences during the postoperative period were observed in patients undergoing “open” and laparoscopic surgery; the frequency of postoperative complications was also approximately the same in both cases.Conclusion. Improvements in contemporary diagnostic methods have led to a sharp increase in the detection rate of small tumours. The results of studies comparing nephrectomy and kidney resection with a healthy contralateral kidney indicate the validity of the organ-preserving approach with small tumour sizes and localisation convenient for resection. In this regard, recently there has been a trend towards a wider use of kidney resection in renal cell carcinoma. Increased emphasis on the quality of life of cancer patients has led to an active study of the possibilities of using modern technologies in kidney cancer surgery.

Published: November 2018

Based on light invariance and electric conservation a four bosons electromagnetismÂ is proposed. It enlarges the electric charge conservation beyond displacement currentÂ and Dirac charge to a new physical situation where the electromagnetic phenomena isÂ mediated by the usual photon plus a massive photon and two additional charged vectorÂ bosons.Considering the enlarged abelian gauge symmetry U(1) SO(2) transforming under aÂ same gauge parameter a non-linear electromagnetism involving four bosons is introduced.Â It deploys a Lagrangian containing massless, massive and charged elds with three andÂ four vector bosons interactions. The corresponding Noether's relations and classical equationsÂ of motion are studied. They provide a whole dynamics involving granular, collectiveÂ terms through antisymmetric and symmetric sectors. It develops a new photon equationÂ which extends the Maxwell's one. Self interacting photons are obtained.A four boson electromagnetic ux is derived. It expresses an electromagnetism transferingÂ 4Q = 0 and j4Qj = 1, not more limited to just a massless photon. There is a newÂ electromagnetic owing to be understood, where aside of electric charge conservation, itÂ appears a neutral electromagnetism. There are six neutral electromagnetic charges beyondÂ electric charge as consequences from non-linearity. Two are derived from the secondÂ Noether identity and four from variational continuity equations.Â An electromagnetic ux being conducted by a whole physics is generated. Based onÂ elds set, it develops a determinism under the meaning of directive and circumstance.Â Interpreting that, light invariance concises the photon as directive, the photon becomesÂ a whole maker. It assumes the symmetry command which will control the conservationsÂ laws and opportunities. Consequently, one combines the symmetry equation derived fromNoether theorem with the four equations derived from variational principle, and an effectiveÂ photon equation is obtained. A kind of Navier-Stokes electromagnetic ow isÂ derived. It yields a four bosons electromagnetism preserving electric charge conservationÂ plus introducting the meaning of chance through symmetry management.

Published: November 2018

The greatest advantage of Sn-Zn eutectic is its low melting point (198 oC) which is close to the melting point. of Sn-Pb eutectic solder (183 oC), as well as its low price per mass unit compared with Sn-Ag and Sn-Ag-Cu solders. In this paper, the effect of 0.0, 1.0, 2.0, 3.0, 4.0, and 5.0 wt. % Al as ternary additions on melting temperature, microstructure, microhardness and mechanical properties of the Sn-9Zn lead-free solders were investigated. It is shown that the alloying additions of Al at 4 wt. % to the Sn-Zn binary system lead to lower of the melting point to 195.72 ËšC.Â From x-ray diffraction analysis, an aluminium phase, designated Î±-Al is detected for 4 and 5 wt. % Al compositions. The formation of an aluminium phase causes a pronounced increase in the electrical resistivity and microhardness. The ternary Sn-9Zn-2 wt.%Al exhibits micro hardness superior to Sn-9Zn binary alloy. The better Vickers hardness and melting points of the ternary alloy is attributed to solid solution effect, grain size refinement and precipitation of Al and Zn in the Sn matrix.Â The Sn-9%Zn-4%Al alloy is a lead-free solder designed for possible drop-in replacement of Pb-Sn solders.Â Â

By following electron beam gun evaporation technique, the magnetic multilayers in the configuration, [Mn(60nm)/Al(20nm)]n; n =1, 2 and 9 were deposited at 473K,Â under high vacuum conditions. From grazing incidence X- ray diffraction (GIXRD) studies, the grain sizes were determined and they were in the order of few nanometers. Atomic force microscope (AFM) were employed to study surface structure and grain sizes. The magnetization as a function of field at 150K and 200K have been measured using the MPMS SQUID - vibrating sample magnetometer (VSM). From the hysteresis loops, coercive field, saturation magnetization, remanent magnetization and antiferromagnetic coupling were determined. All the three films hinted at the existence of at antiferromagnetic interaction between Mn layers through Al layer. Electrical resistivity in the temperature range from 5K to 300K has been measured. Films exhibited semiconducting to metallic transition. The power law variation of resistivity with temperature was established for the metallic region. Conductivity data for semiconducting region of a film has been analysed using polaran hopping models, activation energy and density of states at Fermi level were established. This is for the first time that antiferromagnetic coupling between Mn layers through interfacer layer and semiconducting to metallic transition have been noticed in the present configuration of [Mn/Al] multilayers.
Effect of rapid solidification on microstructure, creep resistance and thermal properties of Sn-10 wt.% Sb- 3 wt.% X ( X= In, Ag, Bi and Zn) lead-free solder alloys
Authors: Shalaby Rizk Mostafa 
Published: November 2018

AbstractThe harmful effects of lead on the environment and human health, coupled with the threat of legislation, have prompted a serious search for lead-free solders for electronic packaging applications. The melt-spinning processes of ternary Sn-10 wt.%Sb-3 wt.%X (X=In, Ag, Bi and Zn) were analyzed using x-ray diffractometer (XRD), scanning electron microscopy (SEM), differential scanning calorimetry (DSC) and Vickers hardness tester (HV). The investigation showed that, the addition of a small amount of the third element enhances the ductility of the Snâ€“10 wt.% Sb lead-free solder due to the formation of a fine, homogeneous ternary microstructure.. It is concluded that, the addition of 3.0 wt% Ag improves the grain size of the ternary microstructure. Moreover, SnSb intermetallic compound, precipitated finely from the solid tin solution near the grain boundaries with antimony. This fine precipitated intermetallic compound suppresses the coarsening of the ternary structure and thus enhances solder ductility. Structural and microstructural analysis revealed that the origin of change in mechanical behaviors was due to refined beta-Sn grains and formation of intermetallic compounds (IMCs) SnSb, InSn19, Î²-In3Sn and Ag3Sn. The results indicated that the melting point of Sn-10Sb-3 wt.% Ag and Sn-10 wt.%Sb- 3 wt.% Zn alloys reduced toÂ 230 and 240 ËšC respectively.Â In particular, the zinc addition at 3 wt.%Â is the most effective in improving solder ductility. The good creep resistance of Sn-10 wt.% Sb-3 wt.% Zn lead-free solder correlated to a large Î²-Sn grain size and complete soluble of SnSb IMC particles in the Î²-Sn matrix.
