Study on the Treatment of Postoperative Pain in Patients Operated for Incisional Hernia by Open or Laparoscopic Approach
Postoperative pain is a common symptom in the postoperative period in patients treated for incisional hernia, often refractory to treatment. The purpose of the this paper was to conduct a comparative study on the need for analgesic medication in patients operated for incisional hernia through a classical open approach and a laparoscopic approach. In this respect, we performed a retrospective observational study over a period of 4 years in which we introduced 92 patients operated for incisional hernia in the Surgery Clinic No. 1 of the Emergency County Hospital Tirgu Mures. For the reconstruction of the abdominal wall we used prosthetic materials (surgical meshes). All patients included in the study received only metamizole sodium as analgesic medication. The patients studied were divided into two groups: group A (consisting of 57 patients where open, classic surgical approach was used) and group B (consisting of 35 patients treated using a minimally invasive laparoscopic approach). It was observed that on the day of surgery and during the first two postoperative days there are no statistically significant differences in the need for analgesic medication between the studied groups. Instead, starting with the third postoperative day, the need for analgesic medication is much lower in patients where laparoscopic surgical procedure was used than in those where open, classic surgical approach was used.
Simulation of Thermal Transfer Through the Polyamide Intake Manifold
The aim of the present study is to model the steady heat transfer of the engine polyamide intake manifold. Under the condition of a steady flow, the intake manifold wall temperature and the intake air temperature were measured to examine the effect of the thermal boundary layer on the heat transfer. Experimental data is used to generate the numerical model of airflow simulation through the intake manifold.
Transarterial Chemoembolization (TACE) with Lipiodol® in HCC PatientsTechnical, clinical and imagistic aspects
Hepatocellurar carcinoma (HCC) is the most frequent primary hepatic tumor, the vast majority of patients have less than a 12 month survival rate. The aim of this study was to evaluate the efficacy of TACE in patients with HCC, based on a case series and literature review. The study included 12 consecutive patients with HCC who underwent surgical treatment (resection, liver transplantation ± resection) at the Department of Transplantation and Surgery, Semmelweis University, Budapest, during 2009-2015. All the patients received at least one TACE session. Patients with BCLC B-stage who benefit from TACE and another alternative therapy (eg, RFA) may be associated with or exhibit tumor stagnation, or tumor necrosis in most cases. In C BCLC stages, desperate cases - the two patients to whom TACE was the last therapeutic attitude, despite the predicted prognosis, TACE assured the prolongation of life and increased life quality. In the majority of patients in this study, stage A BCLC, chemoembolization was a therapeutic attitude that allowed subsequent liver transplantation (when it was not feasible initially due to tumor size) or liver resection in apparently inoperable cases. The arterial chemotherapy is the unanimously accepted indication in patients with stage B, BCLC. The data presented encourages us to opt for TACE with the intention of destaging BCLC and giving an operability character to the hepatic tumors (resection ± hepatic transplantation). In stage C BCLC, TACE can be a last attempt to improve the quality of life and to control tumor progression.
Use of Biopolymers in Designing Edible Packaging Materials for Food Industry Development of statistical models
This study aims to develop biodegradable and edible materials based on hydrocolloids and to analyze their physical and mechanical properties for use as food packaging. Edible packings were obtained from a hydrocolloid matrix (agar, starch, sodium alginate), plasticized with glycerol in different proportions (33.33% and 16.7% from the total amount of polysaccharides used). The physical and mechanical properties were analyzed. The best results were obtained with agar- sodium alginate packing, plasticized with the highest amount of glycerol.
Experimental Results of Siloxanes Rubber Reinforced with Magnetic Fillers Used to Protect the Uman Factor to Electromagnetic Radiation
The character of the original paper is to provide electromagnetic radiation absorbing material that attenuation characteristics of the electromagnetic field very good, as compared to the absorbent materials studied to date. This paper presents results of research on processing, characterization and behavior of composite materials based on silicone rubber used for electromagnetic shielding. In this work silicone rubbers is reinforced with magnetic fillers (iron silicon). The obtaining of composite materials was with the aid of a doctor blade technique. Doctor blade technique is a coating technique widely used for producing thin films on large area surfaces. The samples were processed in the laboratory using a plated nettling (PN), that was impregnated with a silicone rubber based composite containing powder of iron silicon (SI). Were achieved measurements of the both parts of the materials obtaining. These have shown an electromagnetic shielding effectiveness the order of 3.35-41.62 dB (white face) and 3.53-41.42 dB (gray face), in 1-18 GHz frequency range according to SR EN 50 147-1:1999. The paper tries to identify an absorbent material with the ability to protect human beings of electromagnetic radiation that surround us every day and every moment. With the exponential increase in development of commercial, aerospace, military and scientific electronic devices in modern society, electromagnetic radiation is becoming the fourth public pollution after the air, water and noise ones.
Biopolymers - Carbon Sources for Composite Materials Used as Adsorbents for As (V)
Large areas of S-E of Asia (Bangladesh), East of Europe (Hungary, West of Romania, Serbia), Nord and South America contain deep ground waters contaminated with arsenic. In these areas the quantity of arsenic in deep aquifers exceeds maximum allowed concentration of 10 µg/L. In order to use these water sources new adsorbent materials are required for their treatment. A composite material based on carbon and iron-oxide (used as surface modifier) present many advantages such as: chemical stability, higher removal efficiency, possibility of regeneration and very good selectivity for As(V) ions due to presence of iron-oxide particles onto the surface. The purpose of this study was to develop a new method to obtain a composite material using cellulose and soluble starch as carbon sources for the adsorbent material and iron chloride as precursor for the surface modifier. Produced composite material was characterized using several methods: TG-DTG, SEM, EDX, RDX and FT-IR. During experimental test obtained adsorbent material was used as adsorbent for As(V) removal form aqueous solutions. Arsenic residual concentration was measured using ICP-MS method. Maximum adsorption capacity obtained for adsorption experiments was 280 µg As (V)/g of adsorbent material.
Evaluation of Stable Balance Capacity by Using Bosu Ball Surfaces on Different Pressure Levels
The purpose of the study was to evaluate the way in which bimanual and unimanual balanced balance values depend on the technical characteristics of using both Bosu ball surfaces in relation to three pressure levels: 0.6 atm., 0.4 atm. and 0.2 atm. The results have shown that steady manual balance is dependent on the characteristics of the equipment used. The lower the ball’s pressure, the balancebalance becomes worse. Testing the stable hand-balance on the round-up has scored better than the round-side down of Bosu ball.
General Treatment Principles in Alergies-Plastic Materials
The occurrence and evolution of the disease depend on the properties of the organism, the cortical inhibition prevents the development of anaphylactic shock in humans. In some people, the increased and altered sensitivity manifests itself in the form of idiosyncrasy. In idiosyncrasy, the reactivity of the organism is altered from different substances of antigenic nature These substances can be food (milk, strawberries, eggs) or drug substances (iodine, iodoform, bromine, etc.) (drug idiosyncrasy whose symptoms are not related to the specific pharmacodynamic properties of the substance), plastics (prostheses, babies’dummy, etc.). The allergic reaction can be divided into two successive stages: a first stage of allergy, characterized by the formation of allergic type antibodies, their spread and fixation on certain tissues, and the second stage, of antigen –antibody, which represents the reaction In both stages there are both phases of immunological specificity (antibody production, antigen binding to the antibody) as well as non-specific phases in which the allergen and the antibody behave banal, non-immune (enter the body, circulate) or participate in reactions without immunological specificity (histamine release, etc.) The allergy therapy will appropriately include both specific methods and non-specific methods. Specific methods are only two: stopping the allergen input (allergen deficiency) and specific desensitization.Material and Method: A sample of 183 patients was studied in the present study between 2013 and 2017 with suspicions of hypersensitivity to dental materials for local or general symptoms. Results and discussions: A more severe allergy can be manifested in the dental office, is caused by the local anesthetic. The dentist has several local anesthetics, and through a well-done questioning, he will decide which type of anesthesia is the one indicated. For these reasons, an allergic reaction to the anesthetic is less common, but its manifestations are rather severe if it does not intervene in time. Conclusions:Dental biomaterials, in addition to mechanical and chemical resistance, should not contain toxic diffusible elements in the general circulation, elements with allergic or carcinogenic potential.
Determination of Correlation Between Composition, Rolling Parameters and Mechanical Characteristics of the Hot Rolled Steels
The controlled lamination of thick sheets involves the use of algorithms for choosing the rolling parameters: the initial heating temperature, the lamination scheme (the distribution of the total thickness reduction on each rolling cage, the number of passes through each cage and the distribution of the thickness reduction on each passage, intermediate cooling - cooling time and speed), and the temperature of the product obtained at the end of the rolling. The complexity of the phenomena, which occur during the hot plastic deformation process and which must be sufficiently well mastered in order to obtain reproducibly the technical specifications imposed on the products with different destinations, is the justification for this work. The data provided by Arcelor-Mittal Galati was used to obtain the mathematical model. Equations that correlate the main mechanical characteristics with the chemical composition of the steel and the parameters of the hot rolling pattern used are presented.
Research Related to Breast Implant-associated Anaplastic Large Cell Lymphoma and its Influence on the Decision-Making Process Related to Reconstructive Techniques Analysis of a series of cases and literature review
The worldwide increasing number of reports related to new cases of Breast Implant-associated Anaplastic Large Cell Lymphoma (BIA-ALCL) raises the interest of the scientific community in understanding the pathophysiology and the prognosis of these patients. This material presents the impact that BIA-ALCL exerts on the reconstructive options for patients who have undergone mastectomy. The research is based on data obtained from the analysis of a group of patients who have undergone 71 surgeries performed within the National Breast Reconstruction Program between 2015 and 2019. The statistical analysis revealed that 35.14% of the patients that were examined during the breast reconstruction consult refused the use of alloplastic techniques by invoking the potential associated risks described in the insufficient documentation of BIA-ALCL pathophysiology. Improving BIA-ALCL detection and reporting systems has led to an accelerated increase in the number of new diagnosed cases, determining the patients’ reticence towards the use of alloplastic reconstructive techniques.
