Published: April 2019

Mumtaz Qadri sentenced to death and Salman Taseer’s assassination were one of the conflicting religious issues of the country. In such conflicting environment dissemination of news through media has strong social and cultural influence on society. Daily express and Daily The Nation portrayed both issues with different angles and perceptions. This study relied upon method of content analysis of the two well-known Pakistani newspapers Daily Express and Daily The Nation. In this study researcher analyzed sixty two editions of the selected newspaper. The result of the study shows imbalance coverage on Salman Taseer and Mumtaz Qadri’s cases. Daily Express and Daily The Nation covered inadequately both the issues of religious tension that fuel more religious tension in the country and the nation is still curious between right and wrong. Both the newspapers have severely underestimated the severity of Mumtaz Qadri and Salman Taseer’s issue.

The aim — to improve the results of treatment of patients with arterio‑venous forms (AVF) of congenital vascular malformation (CVM) of extremities based on the study of etiopathogenetic aspects of pathology.Materials and methods. Work is based on data of complex clinical research and surgical treatment of 155 patients with the arteriovenous forms of congenital vascular malformation of extremities. There were 65 (42 %) men, 90 (58 %) women, average age — 25.1 ± 10.4 years. The children’s age group (up to 18 years old) is formed of 53 (34 %) persons. The analysis of clinical material is viewed depending on the clinical‑anatomical forms of CVM, which were subdivided into 11 groups on the basis of «working» classification scheme «VASC +T»: I—VII — macrofistulous forms (trunkular, extratrunkular, combined), VIII — IX — micrоfistulous forms, X—XI — mixed or combined forms (with predominance of venous component and presence of single microfistulas). Distribution by prevalence: diffuse forms — groups I — IV, VIII, X; localized forms — groups V—VII, IX, XI. Assessment of chronic arterial and venous insufficiency for each patient was carried out.Results and discussion. Diffuse macrofistulous AVF of CVM are hemodynamically more severe, causing the hypertrophy of soft tissues and more expressed clinical displays of chronic arterial (26 (17 %)) and cardiac (25 (16 %)) insufficiency. Diffuse microfistulous CVM (group VIII) and mixed forms with existence of microfistulas (group X) are characterized by more severe manifestations of chronic venous hypertension (88 (56.8 %)) and vascular‑bone syndrome (56 (36 %)). The most severe manifestations of systemic hemodynamic disorders were revealed in diffuse macrofistulous forms, although, according to most parameters, disturbances in diffuse macro‑ and microfistulous AVF of CVM are comparable and of the same type. Pathomorphological (66 (45.8 %)) and immunohistochemical studies (10.7 %) revealed the presence of proliferative activity of angiomatous tissues and degenerative changes in the walls of the angiodysplastic vessels both due to developmental defects and pathological disorders of hemodynamics. The source of progression of AVF of CVM is vessels of the microvasculature (capillaries) and microfustulas, proceeding from the level of VEGF and Ki‑67.Conclusions. The study of hemodynamic and pathomorphological aspects of the pathogenesis of AVF of СVM is necessary for planning of an individual differentiated approach in diagnosis and treatment, depending on the clinical and anatomical form of the disease.

The aim — to analyze the features of the course and the main factors of development of pulmonary embolism (PE).Materials and methods. During the period from January 1, 2014 until July 1, 2018, 774 patients with acute pulmonary embolism aged from 21 to 88 years (average age 59.1 ± 13.9 years) were hospitalized at Kharkiv City Clinical Hospital №8. Intra‑hospital mortality was 4.9 % (38 patients). The criterion for inclusion in the study was acute pulmonary embolism, diagnosed by the results of multispiral computed tomographic angiography of the pulmonary arteries. All patients underwent general clinical examination, standard transthoracic echocardiography and ultrasound doppler examination of the lower extremity veins. The risk of venous thromboembolism and prognosis according to generally accepted scales were evaluated.Results and discussion. Most of the examined patients (83.8 %) had 2 and more risk factors for venous thromboembolism. Every fifth patient had an oncological disease, in particular, in 5.8 % of patients, it was first detected in a targeted search. According to the MCT‑angiography of the pulmonary artery and/or echocardiography, 72.8 % of patients had signs of dysfunction of the right ventricle. Persons with high and moderately high risk of early death (68.6 %) whose treatment regimens included thrombolytic therapy prevailed among the examined patients. In treatment of patients with low and moderate‑low risk, preference was given to new oral anticoagulants.Conclusions. In the period from 2014 to 2017 there was an increase in cases of acute pulmonary embolism verified by MCT‑angiography, which can be explained by an increase in the incidence of pulmonary embolism and its better detection. The disease was diagnosed with the same frequency in men and women, but women were almost 10 years older than men. Hospitalization of patients with pulmonary embolism in one hospital improves the quality of treatment, as evidenced by a decrease in mortality from 8.8 % in 2014 to 3.9 % in 2017.

The aim  — to analyze the results of complex treatment of patients with carotid artery stenoses and abnormalities of the organ of vision.Materials and methods. The analysis was conducted of the results of the examination and treatment of 27 patients with changes in the visual fields and lesions of the carotid arteries in V. T. Zaitsev Institute of General and Emergency Surgery and Medical Center «Ophthalmika» during 2017—2018 years. The patients were divided into 2 groups: I group — 16 patients in whom the defeat of the carotid arteries required only conservative therapy and II group — 11 patients with hemodynamically significant stenosis or an unstable plaque that underwent carotid endarterectomy.Results and discussion. We evaluated the immediate results of the operation in a comprehensive manner based on the degree of change in clinical status, the presence of postoperative complications and data of instrumental studies. In I group on the background of disaggregant therapy and treatment with statins, the progression of the disease in the form of a narrowing of the visual fields on static perimetry was fixed in two cases, while stenosis of the internal carotid artery increased by 5 — 10 %. In II group, all operated patients had no complications in the postoperative period, enlargement of the fields of vision and expansion of the visual fields and improvement in visual acuity was noted in 10 patients. Complications in the form of a stroke, reduced vision and bleeding were not observed in any case. In two cases, on day 3, reperfusion syndrome manifested itself.Conclusions. Patients with a concentric narrowing of the visual fields and central scotomas should be screened for lesions of the carotid arteries. In case of hemodynamically significant stenosis or the presence of an unstable plaque, the patients must undergo carotid endarterectomy at the first stage, which reduces the risk of ischemic stroke and improves visual acuity and visual field.

The article deals with classification issues, the current state of medical and surgical treatment of chronic diseases of the veins of the lower extremities, widely used in world practice, innovative domestic developments based on electrocoagulation and electric welding technologies, as well as their comparative characteristics among themselves and with laser methods based on their own experience.The aim — to compare effectiveness of open and minimally invasive surgical techniques in patients with varicose disease (VD) and post‑thrombotic disease (PTD) of the lower extremities, to assess the possibility of Ukrainian high‑tech developments using.Materials and methods. Analysis was conducted of surgical treatment of 94 patients with VD for the period from 2014 to 2017 and 81 patients with PTD (the period from 2002 to 2010) in the «Olexandrivska» clinical hospital in Kyiv.Results and discussion. The results of treatment were evaluated at 4 weeks, 3 months, and 6 months after surgery by sonographic criteria, the presence of local edema, the dynamics of the trophic changes in soft tissue of the shin. After 1 month, a slight improvement was fixed at 18 % of the patients of the main group, moderate improvement — at 74 %, significant improvement — at 8 %. In 3 months the estimated effectiveness was 2 %, 12 %, 86 %, in 6 months — 2 %, 6 %, 92 %, respectively. The average length of hospital stay for patients in the main group was 2.4 ± 0.4 days, whereas in the control group this indicator was 5.2 ± 1.2 days.Conclusions. Endovenous laser coagulation and subfascial endoscopic dissection are effective, low‑impact methods for treating lower limb varicose and post‑thrombotic diseases of the lower extremity veins and should actively supplant open methods of surgical treatment. Ukrainian developments using high‑frequency electric welding and electrocoagulation technologies could take leading positions in phlebology.

The prevalence of peripheral arteries disease (PAD) ranges from 3 to 10 % in the general population, reaching 15 — 20 % in subjects older than 70 years. PDA affects 27 million people in Europe and the USA. The annual number of cases of critical lower limbs ischemia (CLLI) is from 500 to 1000 new cases per 1 million of the population, with a high level among patients with diabetes.The aim — to improve the results of treatment of patients with CLLI through the development and implementation of methods of autologous transplantation of multipotent mesenchymal stem stromal cells.Materials and methods. The study was conducted on the basis of two clinical centers of the Department of Surgery № 4 of O. O. Bogomolets National Medical University — vascular surgery department of Alexandrovska clinical hospital and clinic of vascular surgery of the Main military hospital Ministry of Defence of Ukraine and had the following design: 1 period — screening, 2nd period — randomization and distribution of patients by treatment groups, 3rd — treatment, 4th — period of observation (3 years). Sampling of subcutaneous fat, cultivation and transplantation of autologous mesenchymal stem cells according to the method proposed by us were carried out to 41 patients.Results and discussion. The frequency of preservation of the lower limbs in patients who were injected with adipocyte stem cells (ASC) was statistically significantly higher than in patients who used other types of therapy, and was 82 % after three years of follow‑up.Conclusions. Therapeutic mechanism of action of ASC, research on of animal models and in patients, mostly lies in the fact that the growth of blood vessels occurs in ischemic lower limb, possibly, through the interaction of local vascular and inflammatory cells and injected ASC. As a result, patients who received this type of therapy had a smaller percentage of performed amputations than patients who did not receive it.

The aim —  to improve the methods of treatment of carotid pathology by analyzing the frequency of the cranial nerves’ lesions through generalization of the literary sources and the results of own observations.Materials and methods. A review of the latest world‑wide‑scale studies (NYCAS, ECST, NASCET, CREST, VSGNE) and analysis of statistical data, dedicated the problem of cranial nerves’ lesions after surgical interventions on the carotid arteries, was conducted. The frequency of cranial nerves’ lesions was retrospectively analyzed in the total number of operations on brachiocephalic arteries at vascular surgery department of Lviv Regional Clinical Hospital for the period from 2008 — 2017 years (1373 operations). The presence of stable or transient cranial nerves’ lesions in the early and late postoperative period was documented by the neuropathologist and the otolaryngologist.Results and discussion. According to world statistical studies, the frequency of cranial nerves’ lesions after surgical interventions on the carotid arteries is 3 — 27 %, according to the European Association of Vascular Surgeons — 5.1 %. The results of American studies are closed to this value: NYCAS — 5.5 %, NASCET — 8.6 % and CREST — 4.7 %. The most frequently injured are: n. hypoglossus, n. glossopharyngeus and n. auricularis magnus. At vascular surgery department of Lviv Regional Clinical Hospital, the frequency of cranial nerves’ lesions after surgical interventions on the carotid arteries was 7.2 %. The most frequent were injuries of n. vagus, n. hypoglossus and n. glossopharyngeus. Clinical symptoms of injury largely regressed during 1 year. In the cases of atherosclerotic lesions of carotid arteries, the higher rates of postoperative neurological symptoms were observed among symptomatic patients in comparison with asymptomatic ones.Conclusions. The frequency of cranial nerves’ lesions according to the data of literary sources is within the range of 3—27 %. N. vagus, n. hypoglossus, and n. glossopharyngeus have highest rate of frequency of the lesion after surgical intervention on the carotid arteries. The injury process is largely reversible within one year after surgery.

The aim —  to analyze the level and structure of primary (PD) and accumulated disability (AD) due to chronic venous diseases of the lower extremities (CVDLE) over the past five years in Ukraine.Materials and methods. The analysis of primary and accumulated disability due to CVDLE was done. The data was obtained from all centers and bureaus of medical and social expertise of the regions of Ukraine and the city of Kyiv, except for Donetsk, Lugansk regions and the Autonomous Republic of Crimea. The main nosological forms that led to disability were varicose and post‑thrombotic disease (PTD) of the lower extremities. The demographic, social and gender structure of PD and AD was analyzed with consideration of severity of disability.Results and discussion. Over the past five years, in Ukraine, the PD level due to peripheral vascular diseases decreased from 0.84 to 0.76 per 10 thousand adults and from 0.69 to 0.62 per 10 thousand of working‑age population. In the structure of PD due to peripheral vascular diseases in the adult population in 2017, the proportion of CVDLE was 30.8 %. In the structure of PD of working‑age population it was 48.9 %, which was 1.3 and 1.2 times higher than the corresponding figures in 2013. The overall level of disability due to CVDLE compared with 2013 tended to decrease from 1.26 to 1.19 due to PD. Over five years, PD due to CVDLE was characterized by almost two times increase in the number of young people with disabilities, with a simultaneous 1.3 times decrease in the proportion of persons with disabilities in mature age due to PTD. In the group of patients under 30 years of age, the disability group due to CVDLE was initially established in 2.8 % of cases. In the structure of AD due to PTD, an increase in the number of persons of mature age was determined.Conclusions. In the structure of peripheral vascular diseases over five years, the proportion of CVDLE increased by 1.3 times among adults and 1.2 times — among the working‑age population. The main cause of PD due to CVDLE remains PTD (71.4 %) with an increase in the incidence of severe disability by 1.2 times. Over the course of five years, the proportion of PD among young people due to varicose vein disease increased by 1.9 times, indicating a low level of medical rehabilitation. The analysis of the level and structure of disability due to CVDLE over the past five years in Ukraine has identified a negative tendency, which requires improved approaches to medical and social expertise and rehabilitation.

In patients with thyroid dysfunction, various violations of coagulation and fibrinolysis can be observed: from subclinical, with only laboratory changes, to clinically significant thrombosis or fatal hemorrhages. The state of hyperthyroidism is often accompanied by an increase in coagulation factors (II, VII, IX and X) and an increase in serum levels of homocysteine, fibrinogen, von Willebrand factor, inhibitor of tissue plasminogen‑1 activator and antithrombin III. The clinical manifestation of this condition can be thrombosis of various localizations. A particularly significant and common risk factor for venous thromboembolism is an increase in factor VIII. Patients with hyperthyroidism manifested a state of increased adrenergic activity, which can directly contribute to an increase in the synthesis of factor VIII. In parallel, the process of reducing the activity of the fibrinolysis system is noted: a decrease in the serum level of tissue plasminogen activator, shortening of the activated partial thromboplastin time. Evaluation of the patient's procoagulant status should be carried out for diagnosis and timely appointment of anticoagulant therapy. Cytomegalovirus (CMV) infection is a common disease, especially in young people. The literature commented on cases of thromboembolism of different localization, such as deep vein thrombosis and pulmonary thromboembolism, in patients with CMV infection. However, in the literature, we did not find a clinical case of a combination of acute CMV infection and hyperthyroidism complicated by disorders of the coagulation system and fibrinolysis. This clinical case describes multiple thromboses in a young patient with subclinical hyperthyroidism at the background of cytomegalovirus infection.

Problem of gastrointestinal bleeding treatment remains relevant, due to the high mortality. Endoscopic haemostasis reduces both general and postoperative mortality 3 — 4 times. There are a number of methods for endoscopic haemostasis: chemical, injectable, monopolar coagulation, argon plasma coagulation, laser coagulation and clapping.The aim — to substantiate experimentally and morphologically the use of high­frequency welding bipolar electrocoagulation with the EK­300M1 apparatus in gastrointestinal bleeding endoscopic treatment and introduce it into clinical practice.Materials and methods. An experimental study of a new local haemostasis method for bleeding vessels and erosions (patent N 124885 dated 25.04.2018, A method for treating patients with gastrointestinal bleeding) with morphological verification of the state of the vessels was done with experimental study on 10 pigs aged 5 — 7 years, weighing 85 — 100 kg. For high­frequency welding bipolar coagulation, two probes were used, connected to the EK­300 M1 apparatus in the overlap mode: 2.2 mm in diameter (patent N 115147 dated 04.04.2017) with a convex electrode (N 1) and 3.2 mm (modified) with a concave electrode (N 2).Results and discussion. It has been established that to stop bleeding from vessels with a diameter of up to 1 mm, it is most effective to use probe N 1 with an exposure time of 15 s; for vessels with a diameter of more than 1 mm­ probe N 2 with an exposure time of 30 s.Conclusions. High­frequency welding bipolar electrocoagulation has advantages over other methods of endoscopic haemostasis and can be recommended as the method of choice for the gastrointestinal.

The aim — improvement of a soft tissue purulent diseases treatment in HIV­infected patients by a surgical treatment with ultrasound cavitation combination.Materials and methods. The analysis of complex surgical treatment of soft tissues apostasies and phlegmon in 124 HIV­infected patients was conducted. Patients were divided into 2 groups, depending on the strategy of treatment. In the first (main) group (n = 26) the combination of surgical treatment with ultrasonic cavitation was applied. Ultrasonic cavitation was used in post­operative period during I (exudative) phase of wound process before incarnation appeared. By comparison, in the second group (n = 62) only surgical treatment was applied.Results and discussion. The ultrasonic cavitation in treatment of soft tissue purulent diseases in HIV­infected patients allowed to stop local inflammation and achieve partial incarnation of wound surface on the average in 13.2 ± 0.5 days in the first group and in 15.9 ± 0.6 days in the second group. The level of bacterial titer of wound secretion by 15.5 ± 0.6 days was not higher than the commonly accepted critical one in comparison to the classic situation, in the second group it was on the 16.8 ± 0.7 days. Terms of inpatient treatment were: 16.2 ± 0.8 days in the first group and 21.2 ± 0.9 days in the second group accordingly.Conclusions. The usage of ultrasonic cavitation in the complex surgical treatment of soft tissue purulent diseases in HIV­infected patients significantly increases the time of wound cleaning, accelerates incarnation by 1.2, reduce the time of treatment of patients with concomitant HIV infection by 1.3 times in comparison to the classical approach of cleaning, by means of mechanical cleaning of the wound from purulence and necrotic tissue by ultrasound of low frequency in combination with antiseptic.
Thrombophilia, as the cause of vessels thrombosis of atypical surgical localizations
Authors: S. M. Genyk
Published: April 2019

Thrombophilia is a change in the balance of the blood coagulation system, manifested by an increased tendency to thrombosis. The formation of blood clots occurs as a result of a complex interaction between the vascular endothelium, platelets, blood clotting factors, natural anticoagulants and fibrinolytic blood system. The particular danger of intravascular blood clots is that they usually occur suddenly. Thrombophilia of various localizations in surgical patients is a pathology that often remains unrecognized and threatens life. Thrombosis of vessels of atypical localizations (mesenteric vessels, hepatic veins, portal, splenic, veins of the upper limb) arise in patients with hereditary or acquired haemostasis defects. Most often, atypical localization of thrombosis is found in individuals with hereditary haemostasis defects (genetic thrombophilia). If thrombosis of rare localizations is detected, screening for hereditary or acquired thrombophilia forms is required. This allows to select patients with prolonged anticoagulant therapy and obligatory anticoagulant prevention indication in situations, which are related with risk of thromboembolic complications. It has been established that homozygous mutations or a combination of two or more heterozygous polymorphic ones, as a rule, lead to the thrombosis development at a young age and are associated with a tendency to relapse. The detection of thrombophilia is not an absolute indicator for the thrombosis prophylaxis. However, the combination of thrombophilia with a risk factor for venous thromboembolism significantly increases the venous thrombosis incidence and requires measures aimed at their prevention. The presence of thrombophilia contributes to more frequent arterial thrombosis at a young age, as well as in neoplasms and atrial fibrillation.
Dynamic Behavior Analysis of the Slider Crank Linkage using ANSYS Workbench and MATLAB Program
Authors: Swadi Nabil N.
Published: April 2019

This paper is concerned with the study of the kinematic and kinetic analysis of a slider crank linkage using D'Alembert's principle. The links of the considered mechanism are assumed to be rigid. The analytical solution to observe the motion (displacement, velocity, and acceleration), reactions at each joint, torque required to drive the mechanism and the shaking force have been computed by a computer program written in MATLAB language over one complete revolution of the crank shaft. The results are compared with a finite element simulation carried out by using ANSYS Workbench software and are found to be in good agreement. A graphical method (relative velocity and acceleration method) has been also applied for two phases of the crank shaft (q2 = 10° and 130°). The results obtained from this method (graphical) are compared with those obtained from analytical and numerical method and are found very acceptable. To make the analysis linear the friction force on the joints and sliding interface are neglected. All results, in this work, are obtained when the crank shaft turns at a uniform angular velocity (w2 = 188.5 rad/s) and time dependent gas pressure force on the slider crown.

The present work investigates the effect of magneto hydrodynamic (MHD) laminar natural convection flow on a vertical cylinder subjected to sinusoidal temperature oscillation. The governing equations which used are continuity, momentum and energy equations. These equations are transformed to dimensionless equations using vortices-stream function method and the resulting nonlinear system of partial differential equations are then solved numerically using finite difference approximation. A computer program was built to calculate the rate of heat transfer in terms of average Nussle number, velocity distribution as well as temperature distribution for a selection of magneto hydrodynamic parameter range , dimensionless amplitude  and dimensionless time τ΄ (0.2 – 0.8). Numerical solution have been considered for a fluid Prenatal 542 number fixed at (Pr=0.7), Rayleigh number . Generally, the results show that Nu increase as Ra, M and a increase and decrease with τ΄. The effect of Ra and M on the rate of heat transfer is concluded by a correlation. The results are found to be in good agreement compared with the results of [Adams, 1954] for the case of no MHD.

Al-Hussainia sector is the middle sector of Al-Dalmaj irrigation project. In this study, a specified area of Al-Hussainia sector has been selected to be evaluated for its water suitability for irrigation. For Al-Hussainia main drain, the evaluation includes four stages as follows:

1- Chemical evaluation of drainage water, 2-Analysis of drainage water by Aq.Qa software,  3- Leaching requirements computations, 4- Evaluation of the drainage water quality in the specified area of the project using the Geographic Information System (GIS) software. For the chemical evaluation, the most important indicators for the salinity problem considered are (Electrical Conductivity, Total Dissolved Solids, Sodium Adsorption Ratio and Sodium Content). The test results showed that there are no harmful effects from Sodium indicators on crops production while there is a salinity problem. The residual sodium carbonate values were zero for all locations. The analysis of the hydro chemical results by Aq.Qa program shows that the internal consistency of the samples was acceptable. It is concluded that the drainage water of Al-Hussainia sector can be used directly to irrigate wheat and barley without reducing the yield with leaching requirement of 0.25 for wheat for all locations while barley needs a leaching requirement of 0.15 for locations 3,4, and 5 a leaching requirement of 0.17 should be provided for locations 1, 2, and 6. For corn crop, the drainage water is unsuitable for irrigation unless it is mixed with irrigation water to eliminate the salinity hazard. However the mixing ratio is0.5 (1:1) for all locations except location 2 where the mixing ratio needed is0.6 (1:2). The three dimensional spatial analysis using the GIS software (Arc Map V. 9.3) showed that the final model of the study area is of permissible irrigation water quality.

Authors: Al-Gasham Thaar Saud Salaman
Published: April 2019

The test results of six reinforced concrete moderate deep beams with embedded PVC pipes are reported. The tests studied the effect of installation of PVC pipe on behavior of reinforced concrete moderate deep beams. The test parameters were the diameters and locations of the pipes. The dimensions of beams were 1000 mm length, 150 mm width and 300mm depth. One beam was constructed without pipe as control and the remaining five had embedded pipes. Four pipe diameters were used: 25.4, 50.8, 76.2, and 101.6 mm and these pipes were inserted longitudinally either at the center of the beams or near the tension reinforcement. The beams were simply supported and tested under central concentrated load up to failure. The test results indicated that, the pipe diameter less than 1/3 of the beam width had limited effect on the capacity and rigidity of beam. For larger pipes, the ultimate strength of beams decreased between 16.7% and 33.3% and the beams stiffness decreased between 103% and 297%.
