The operation of the hydroelectric power plant is one of the main reasons for the transformation of river runoff. The change in the hydrological regime affects several other processes taking place in the river channel, including the transformation of its geomorphological features. The article presents the impact of the Kaniv and Włocławek dams on the hydrological regime of the middle Dnieper River and the lower Vistula River. The nature and magnitude of changes in the Dnieper and The Vistula rivers flow regime caused by the functioning of the dams were determined using IHA (Indicators of Hydrologic Alteration) and the RVA (The Range of Variability Approach) method. It was demonstrated that the operation of the hydroelectric power plant especially in the hydropeaking system is the cause of a large flow alteration in respect of the frequency and duration of low- and high-flow pulses and the rate and frequency of change in the flow. It was assessed how the change in flow conditions in connection with the deficit of sediments affected the transformation of the Vistula and Dnieper river channels downstream of the dams. Based on our results, the reaction of the fluvial system to changes in the flow regime caused by the operation of the Kaniv and Włocławek hydroelectric power plants consisted in: 1) changing the width and depth of channels; 2) changing the size of the forms separating channels; 3) fixation of the anastomosing fluvial system. More dynamic water flows due to the operation of hydroelectric power plants modify and dynamize the natural process of evolution of a fluvial system into an anastomosing system by causing the incision and narrowing of the main channels, because of which the side channels occupy a higher position above them. On the other hand, the equalization of the water flow in the channels causes a decrease in the water level and the disappearance of the flow in the side channels. As a result, the islands separated by these channels merge and inter-channel areas are formed.

The use of a tuning fork resonator as sensitive element of a gyroscopic sensor has some advantages in comparison with other types of the resonators. For instance, it allows to compensate lateral accelerations in the direction perpendicular to the axis of rotation. At the same time, the task of accurate determination of the carrying frequency of the primary mode of a non-moving tuning fork is of great importance. Thus, in [1] the analysis of vibrations of a gyroscope is built on the evaluation of the first frequency of flexure vibrations of Timoshenko's beam with one rigidly fixed end [2]. As a result, the sensing frequencies of the Bryan's splitting pair [3] of the fork lie below the frequency of Timoshenko's beam, and the resonant frequency of the non-moving tuning fork remained uncertain. The purpose of a present paper is to establish this frequency. In the statement of a problem, concerning real geometric dimensions of the tuning fork elements, we assume that the length of the tuning fork rods l is much more then the radius of the base r: r/l << 1. Then, frequencies of the flexure vibrations of the half-ring lie much higher than the frequencies of the bending vibrations of the rods. It allows us to give a solution for the base in a quasi-static approximation, and to take into account the dynamics of the tuning fork in the solution for bimorph piezoceramic rods. Conditions of coupling between the rods and the half-ring are reduced to the conditions of elastic fixing of the rods, which take into account the geometric parameters r and l.

Optoacoustic tomography is effective in applying to the visualization of objects that have a high coefficient of light absorption relative to the environment. Such tasks include, for example, defectoscopy, vascular imaging, detection and monitoring of tumors, diagnosis of porosity of composite materials, high-precision local measurement of the modulus of elasticity. However, the quality of optoacoustic images largely depends on factors such as noise (equipment or environmental noise) and distortion due to the characteristics of the model and the calculation algorithm. The article proposes an iterative algorithm for improving the quality of optoacoustic images, based on the observation that artifacts increase in magnitude with each iteration, while the nature and location of the distortions remain unchanged. Numerical simulations of the propagation of ultrasonic waves in environments close to soft biological tissues have been performed. In terms of eliminating distortion and artefacts inherent to the method of image reconstruction, an iterative filter was found to be highly effective The effectiveness of the approach is manifested in the use of a small number of iterations.

Published: April 2022

The paper aims to investigate the model of a complicated educational system, built on the basis of general principles of mathematical modeling of complex hierarchical systems. The model consists of three components, the interaction between them is provided by certain conditions. This interaction is the basis for modeling the main parameter of the study - the level of funding required for higher education. An important feature of the modeled system is its controllability, because in a real educational system the controlling influence can be performed as an external management of the system to ensure an average level of funding. For the initial problem of optimal control, which consists of a parabolic equation with a multivalued reaction function of the system, the approximate synthesis problem for a certain class of target functionals with control restrictions is solved. The results of modeling can be used in the development of various models of complex systems, as well as for decision-making in public administration and higher education management.
The role of adipokines in the development of adipose tissue dysfunction and other metabolic disorders

Published: April 2022

The role of specific adipokines in the formation of adipose tissue dysfunction is considered. Obesity is a multifactorial disease that is characterized by excessive adipose tissue accumulation in the body and is a risk factor for the development of several other diseases, including type 2 diabetes mellitus, cardiovascular diseases, and non-alcoholic fatty liver disease. Obesity is one of the main causes of chronic diseases and disability in modern society. Adipose tissue takes an active part in cellular reactions and metabolic homeostasis and does not represent inert tissue only for energy storage. In obesity, excessive accumulation of visceral fat causes adipose tissue dysfunction, which greatly contributes to the occurrence of concomitant diseases. Adipose tissue is capable of synthesizing and releasing a large number of hormones, cytokines, extracellular matrix proteins, growth factors, and vasoactive factors, which are collectively called adipokines, affecting various physiological and pathophysiological processes in the body. Perivascular adipose tissue produces cytokines that affect angiogenesis and peripheral vascular resistance. Adiponectin suppresses the production of glucose in the liver and enhances fatty acid oxidation in the skeletal muscles, which together contribute to a favorable metabolic effect in energy homeostasis, protect cells from apoptosis, and reduce inflammation in various cell types through receptor-dependent mechanisms. Leptin modulates vasoconstriction depending on sympathetic activity while resistin is involved in insulin resistance due to inflammation, wherein its high level determines metabolically unhealthy obesity. Additionally, visfatin plays an important role in the pathogenesis of vascular inflammation in obesity and diabetes mellitus while osteopontin regulates the production of inflammatory mediators by immune cells and omentin plays an important anti-inflammatory and insulin-sensitizing role. The production of most inflammatory mediators in adipose tissue dysfunction increases and contributes to the progression of obesity and related metabolic and vascular disorders. Considering adipokines as biological markers of pathological processes is necessary since their study will create prerequisites for preventive measures and will contribute to the positive treatment process.

Published: April 2022

This study investigated the effects of glyproline neuropeptide compounds (selank and Pro-Gly-Pro) on the white blood cell count and phagocytic activity of neutrophils in 40 nonlinear white male rats aged 68 months with experimental hyperthyroidism. Experimental hyperthyroidism was simulated by intragastric administration of L-thyroxine sodium salt pentahydrate at a dose of 150 g/kg/day for 21 days. All animals were equally divided into four groups: healthy rats (control), rats treated with L-thyroxine sodium pentahydrate (hyperthyroidism), rats treated with selank, and rats treated with Pro-Gly-Pro at doses of 200 g/kg/day intraperitoneally for 21 days, starting one day after the last administration of L-thyroxine sodium pentahydrate. After the animals were removed from the experiment, the white blood cell count and the percentage of lymphocytes, stick, and segmentonuclear neutrophils were calculated, and the phagocytic activity of neutrophils was evaluated. In the case of experimental hyperthyroidism, neutrophilic leukocytosis with a shift to the right, lymphopenia, and decreased phagocytic activity of neutrophils were observed. Glyproline neuropeptides contributed to the correction of observed changes in white blood cell indices and phagocytic processes, which indicates the immunocorrigating effect of the test compounds. Thus, glyproline neuropeptides demonstrated pronounced immunotropic activity, which manifested in the correction of changes arising from the leukocyte count and phagocytosis processes. However, further detailed study of the pharmacological effects of neuropeptide agents on experimental hyperthyroidism is necessary.

Published: April 2022

The word "contusion" (contusio) means - blow, bruise. In the good old days, during the wars of the times of the Ochakovskys and the conquest of the Crimea, fragments of the round core often bruised, not injuring, but causing only bruises and bruises. Modern artillery technology has created completely new illnesses and diseases. The study of these morbid phenomena is, of course, not yet complete, but certain considerations must be given wide publicity for further verification and testing.

Goals and Practices in Corporate Sustainability Communication: Doğuş Otomotiv Case
Authors: VATANARTIRAN Omer
Published: April 2022

The concept of sustainability was introduced in 1987 by the United Nations Brundtland Commission,
at a time when global society was experiencing various political, economic and social conflicts. States
developed legal measures for a more sustainable life and placed the topic at the core of their political
agendas. They were followed shortly by non-governmental organizations, municipalities, companies and
the media, who started developing strategies for economic growth that also integrated a sustainable natural
environment and society. Although sustainability practices in the business world sometimes remained
superficial for some companies and did not go beyond an effort to adapt to business trends, the proportion
of corporations that take genuine action for real social change has gradually increased and this has led to
the development of norms in the private sphere. In Turkey, more and more companies have redesigned
their communication strategies in light of the growing awareness around sustainability and the related
social expectations. In this process, it became important to understand the way in which leading companies
experienced this transformation and to what extent they combined sustainability practices with the values
of their stakeholders. With this purpose in mind, this study focuses on Doğuş Otomotiv’s sustainability
values and the communication strategies they implement to spread them. Content analysis was con1ducted
on sustainability reports and websites from a qualitative perspective, and an in-depth interview was held
with a senior Corporate Communications manager. Accordingly, it has been concluded that sustainability
is defined as a participatory, flexible, open communication-based concept among all stakeholders, as well
as a dynamic and broad concept inherent in corporate ethics and company culture. It also appears that sustainability communication takes a different form in different channels depending on the stakeholder
profile, and that in this sense, new media presents both opportunities and challenges.
The Coronavirus Health Crisis, Social Media, and Online Health Information Seeking Behaviour of Older Adults in Nigeria
Authors: UGOALA Bibian , UDENZE Silas
Published: April 2022

Older adults or the elderly are part of the group of peeople that make up a majority of the health burdens
in society, and the outbreak of coronavirus or COVID – 19 has further placed them in a risky position
due to their age. Going by the latter statement, the research examines the impact of social media on this
population’s online health information-seeking behaviour in the face of the global coronavirus health crisis
in Nigeria. The study employed Krejcie and Morgan’s (1970) technique for ascertaining the sample size for a
given population, and arrived at a sample of 384 quantitatively surveyed through a questionnaire. The study
concluded that social media positively impacted the health behaviour of the research population, and the
information sought on social media is reliable, and it also influenced their behaviour positively. However,
the authors warn that online health information seekers, especially older adults, should always exercise
caution as not all information obtained on social media on various health issues, including the coronavirus,
is accurate. Besides, consumers of online health information should be thorough and active users of social
media; they should use their human senses to discern between false and true health information. Further,
they should also verify such information with health professionals if the need arises. Given the limitations
enumerated in this study, the authors suggest that further studies are essential to validate the results of this
research.

Published: April 2022

Kurumsal sosyal sorumluluk iletişiminin (KSSİ) bir aracı olarak reklam; içerdiği mesajları yaratıcı göstergelerle, kısa zamanda geniş kitlelere ulaştırabilme özelliğine sahiptir. Söz konusu bu avantajlar, reklamı kurumsal sosyal sorumluluk (KSS) anlayışının topluma benimsetilmesinde etkin bir yere taşımaktadır. Bu düşünceden hareketle, çalışmanın odağında, ticari markalarca tasarlanan KSS içerikli reklamlar yer almaktadır. Çalışmanın amacı, içerik analizi yöntemiyle, KSS vurgusuna sahip reklamlarda yararlanılan anlatım tekniklerini ve görsel/işitsel stratejileri belirlemektir. Bu doğrultuda, prime time kuşağında yayınlanan KSS içerikli reklamların, tüm reklamlara göre oranı belirlenerek, söz konusu reklam filmlerinde vurgulanan mesajlar, KSS alanı, türü, konusu ve paydaşlar açısından incelenmiş; reklamlarda öne çıkan karakter/canlılar, renkler, nesneler ve seslerin KSS mesajıyla ilişkileri sorgulanmıştır. Araştırma sonucunda; incelenen reklam filmlerinin yalnızca yüzde 5’inin KSS mesajı içerdiği görülmüştür. Söz konusu bu reklamlarda, markaların çoğunlukla sosyal sorumluluklarına vurgu yaptıkları, özellikle sosyal amaç destekli pazarlama mesajlarına yer verdikleri, projenin paydaşları olarak tüketicilerin ve markanın konumlandırıldığı, çevre ve toplum konularındaki sosyal sorumluluk projelerinin ön plana çıktığı görülmüştür. Reklam tasarımında yararlanılan ünlü sesi kullanımı, projeyi çağrıştıran, duygusal nitelikli ses kullanımı, ünlü karakterlere ve çocuk karakterlere yer verilmesi, marka/kurumun görsel kimliği ile sosyal sorumluluk projesinin renklerini içeren görsel tasarım ögelerinin kullanımı sayesinde KSS mesajının etkinliğinin arttırılmasının hedeflendiği belirlenmiştir.

Durante la infección aguda por el SARVS-CoV-2 se produce una desregulación del sistema inmune que puede durar hasta ocho meses después de controlado el cuadro agudo. Esto, sumado a otros factores, posiblemente este asociado con un aumento del riesgo de aparición y concurrencia de enfermedades autoinmunes. La aparición simultanea del síndrome de Guillain-Barré (SGB) y púrpura trombocitopénica (PTI) se ha reportado poco en la literatura, y el SGB raramente se asocia con otra enfermedad autoinmune. Presentamos el caso de un varón que luego de un mes de tener un cuadro agudo de COVID-19 moderado, presentó concurrentemente SGB y PTI con respuesta adecuada al tratamiento.

Published: April 2022

Se realizó un estudio transversal en estudiantes de Medicina de una universidad privada de Lima. El objetivo fue describir el nivel de conocimientos y las actitudes sobre la COVID-19, además de su percepción sobre el rol de los medios de comunicación y de las redes sociales. El 32% no sabía que en los primeros cinco días de la enfermedad, las pruebas serológicas son preferibles para diagnosticar la COVID-19, comparadas con las pruebas moleculares; el 73% reportó estar dispuesto a trabajar como voluntario durante la pandemia y el 94% recibió información falsa sobre la COVID-19 en las redes sociales. Este estudio demuestra que la información sobre el uso de pruebas diagnósticas debe ser reforzada y que se debe tomar en cuenta el alto porcentaje de estudiantes dispuestos a ser voluntarios durante la pandemia de la COVID-19.

Objetivos. Evaluar y comparar la distribución de macronutrientes de las canastas alimentarias entregadas por las municipalidades peruanas durante la pandemia de COVID-19 según dominio geográfico y nivel de presupuesto asignado. Materiales y métodos. Análisis secundario de la base de datos «Consulta de adquisición y distribución de bienes de primera necesidad de la canasta básica familiar» de la Contraloría General de la República. Se realizó un muestreo probabilístico estratificado. Se calculó la distribución del aporte calórico según macronutrientes y se comparó con los intervalos aceptables de distribución de macronutrientes (IADM) del Instituto de Nutrición de Centro América y Panamá (INCAP) y del Instituto Nacional de Defensa Civil (INDECI). Resultados. A nivel nacional la mediana del aporte calórico de las proteínas fue 7,7%; carbohidratos 62,5%, y grasas 28,1%. La proporción de municipalidades con canastas con déficit de proteínas fue de 84%. Las municipalidades con canastas con exceso de carbohidratos variaron de 16,5% (según INCAP) a 35,9% (según INDECI) y con exceso de grasas fue 61,6 % (según INCAP) y 20,2% (según INDECI). Según INDECI, a nivel nacional solo el 9,2% de municipalidades entregaron canastas con distribución adecuada de macronutrientes, aquí destaca Lima Metropolitana con las proporciones más altas; mientras que en la selva este porcentaje fue menor del 5%. Conclusiones. La mayoría de las canastas entregadas no tuvieron distribución adecuada de macronutrientes, en especial las canastas de municipalidades fuera de Lima Metropolitana o las que contaban con menor presupuesto. Los carbohidratos y las grasas fueron los nutrientes que se incluyeron en exceso, mientras que las proteínas tuvieron déficit.

Dudak damak yarıkları, dünya genelinde görülen en yaygın doğum anomalilerinden birisidir. Görülme sıklığı, etnik geçmiş, coğrafi köken ve sosyo-ekonomik duruma göre değişkenlik göstermektedir. Hamilelik sırasında annenin sigara içmesi, alkol tüketmesi, folik asit, B6 ve B12 vitaminlerince yetersiz beslenmesi gibi çevresel faktörler ile beraber genetik faktörlerin etkileşimi, yarık dudak damak oluşumuna sebep olabilmektedir. Dudak damak yarıklarının genetik açıdan incelenmesi için birçok aday gen araştırılmıştır. MTHFR, MTR, MTRR, TGFβ ve PVRL1 genleri dudak damak yarıklarının oluşumuna sebep olan önemli genlerdir. Yarık dudak ve damak oluşumunun erken teşhis edilememesi, embriyogenez sırasında dudak ve damak gelişimini düzenleyen gen ekspresyon kalıplarının ve etkili sinyal moleküllerinin etki mekanizmalarının yeterli bilinmemesinden kaynaklanmaktadır. Yarık dudak ve damak etiyolojisine sebep olan faktörlerin belirlenmesi, yarık dudak damak oluşumunun önlenmesi ve gerekli tedbirlerin alınması açısından çok büyük önem taşımaktadır. Bu derlemede yarık dudak damak hastalığının genetik faktörler ile ilişkisinin belirlenmesi amaçlanmıştır.

This study aims to investigate the effect of CRP in retrospectively on patients who went through percutaneous coronary interference (PCI) with coronary artery disease (CAD) diagnosis and coronary artery bypass graft (CABG) history.MATERIAL AND METHODS: 38 patients with CAD diagnosis and 12 patients with CABG history who underwent through PCI were assessed retrospectively. CRP consists of 5 minutes of warm-up, 10 minutes of joint range of motion, a 15 minute-tone-up exercise for the greater muscle groups, 30 minutes of aerobic exercise through constant heart rate training program by using bicycle ergometer exercise and 5 minutes of cool-down exercise. A total of 30 sessions were applied. The demographic data of the patients were recorded. 6-minute-walk-test (6-MWT), Short Form- 36 (SF-36), and Beck depression inventory were used respectively to assess the functional exercise capacity, quality of life, and the level of depression of the patients for their before and after the rehabilitation process.RESULTS: Physical function (p<0.001), physical role (p=0.001), emotional role (p=0.01), pain (p=0.03), overall health (p=0.04) of life quality parameters, 6-MWT (p<0.001) and value of Beck depression inventory (p<0.001) showed significant improvement after the rehabilitation process of patients with CAD diagnosis. Furthermore, significant improvement was found in physical role difficulty and emotional role (p=0.001), which are from the quality of life parameters, and 6 MWT (p<0.001) and BDI (p<0.001) after rehabilitation in patients with CABG.CONCLUSIONS: The cardiopulmonary aerobic exercise program that is applied together with cycle ergometer exercise improves the functional exercise capacity and the life quality of the patients with CAD diagnosis and CABG history and helps bring down the depression level of the patients.

OBJECTIVE: It is recommended to take a blood culture test in pediatric patients diagnosed with pneumonia. However, the rate of pathogenic microorganisms produced in blood culture tests is quite low. In this study, the results of blood culture tests and some blood test parameters in pediatric patients hospitalized with pneumonia diagnosis were evaluated.MATERIAL AND METHODS: 643 patients who were hospitalized and diagnosed with pneumonia in accordance with ICD10 coding and whose blood culture test was taken between 2016 and 2018 were included in the study. The results of blood culture tests and blood test parameters ((WBC (White Blood Count), ANC (Absolute Neutrophil Count), AMC (Absolute Monosite Count), MPV (Mean Platelet Volume), PDW (Platelet Distribution Wide), PCT (Plateletcrit)) and CRP (C-Reaktif Protein)) were evaluated.RESULTS: The mean age of the patients was 27.1±38.2 months and 41.8% of the patients were female. Blood culture results were positive in 4.0% of the patients (n=26). The platelet count of the patients with positive blood culture (307.3/ml) was lower than those with negative blood culture (360.2/ml) (p=0.035) but no differences were found in the CRP levels (p = 0.095), total white blood cell count (p = 0.069) and MPV (p= 0.846) values. PDW level was found higher (p <0.001) in patients with positive blood culture (12.7±2.6%) than those with negative blood culture (10.4±1.7%). The most frequently isolated pathogen was Staphylococcus Hominis (n=8, 36.4%).CONCLUSIONS: The rate of detection of pathogenic microorganisms in the blood culture test in pediatric patients hospitalized with the diagnosis of pneumonia is at a very low level. In these patients, the demonstration of pathogen bacteria in the blood culture test is valuable for the treatment of the disease and choice of empirical antibiotherapy. It is necessary to conduct studies on the use of other blood parameters in the diagnosis, treatment and clinical follow-up of pneumonia in children.

OBJECTIVE: Operating rooms are work environments where the risk of making mistakes is high in health care areas, as they are areas where stress is experienced at a high level and quick decision-making is required. The ability of operating room nurses to fulfill their roles and responsibilities professionally depends on having sufficient knowledge and skills specific to the field. It is thought the fact that operating room nurses have a grasp of intraoperative period patient care will reduce the risks such as falling, pressure wound, burns, foreign body forgetting, surgical site infection, and increase the quality of the surgery. For these purposes, we aimed to determine the intraoperative patient care knowledge levels of the operating room nurses in the city of Afyonkarahisar.MATERIAL AND METHODS: This descriptive study was carried out with 60 operating room nurses working in the public and private hospitals of the city of Afyonkarahisar , after their informed verbal consent was obtained, between August and September 2014. The data were collected through a survey form consisting of two parts. In the first part, there are 6 questions about the socio-demographic characteristics of the participants. In the second part, a 3-point Likert type questionnaire consisting of 36 items designed by the researchers after the review of relevant literature and taking expert opinion was used to determine the knowledge levels of operating room nurses regarding intraoperative patient care. The SPSS for Windows 18.00 program was used in the evaluation and analysis of the data. Descriptive statistics of continuous variables were shown with mean, standard deviation, median, minimum and maximum values, while descriptive statistics of categorical variables were shown with frequency and percentage.RESULTS: Of the nurses participating in the study, the mean age was 32.03 ± 7.32 (min: 19 max: 50), 86.7% were female, 45.0% had an undergraduate degree, and 73.3% were nursing graduates. It was determined that 61.7% of them had been in the profession for more than 6 years while 53.3% working in the operating room for more than 6 years. The intraoperative period patient care knowledge mean score of the nurses was found to be 26.13 ± 5.42.CONCLUSIONS: As a result of this study, nurses working in the operating rooms of the city of Afyonkarahisar were determined to have a sufficient level of intraoperative patient care knowledge, however, there have been practices identified that need to be corrected and improved.

Authors: Yıldız Ziya
Published: April 2022

AMAÇ: Postperikardiyotomi sendromu (PPS); bütün gelişmelere rağmen kardiyak cerrahi sonrası morbiditenin en sık nedenlerinden biri olmaya devam etmektedir. Koroner arter bypass greftleme sonrası PPS’ e bağlı olarak perikardiyal efüzyon ve dirençli perikarditlerin oluştuğu tespit edilen hastalarımızda kolşisinin oluşan perikardiyal efüzyonları ve enflamasyonu kısa sürede azaltıp tamamen ortadan kaldırmada ve cerrahi müdahaleleri belirgin olarak azalttığı konusunda sanılandan daha etkili olup olmadığını araştırdık.GEREÇ VE YÖNTEM: Ocak 2015 ile Ocak 2020 tarihleri arasında tamamı koroner arter baypas greftleme operasyonu geçiren PPS gelişen 56 hasta retrospektif olarak çalışmaya dahil edildi. Bu hastalardan 24’ünün tedavisinde kolşisin kullanılırken diğer 32 hastanın tedavisinde kolşisin kullanılmadı. Elde edilen sonuçlar karşılaştırıldı. Hastaların gruplar arasında demografik özellikleri, eşlik eden risk faktörleri, risk analizleri koroner arter baypas greftlemede yapılan anastamoz sayıları, drenaj miktarları ve enflamasyon değerleri karşılaştırıldı. Hastalardaki morbidite ve mortaliye etkili faktör araştırılıp incelendi. Kolşisinin hem tedavi üzerine hem de invaziv girişim sıklığı üzerine olan etkinliği araştırıldı.BULGULAR: Çalışma grubu ve kontrol grubundaki hastalar karşılaştırılmıştır. Çalışma grubundaki hastaların tedavisinde kullanılan kolşisinin perikardiyal mayiinin rezorbsiyonunda ve perikardiyal mayinin boşaltılması için gerekli olabilecek cerrahi müdahalenin sıklığının azaltılmasında etkili olduğu tespit edilmiştir.SONUÇ: Kolşisin kullanımı; perikardiyal efüzyon miktarını ve bunun için gerekebilecek cerrahi girişim sıklığını ciddi olarak azaltmıştır. Rutin uygulamada kliniğimizde PPS gelişen hastalarda ilk tercih olarak kullanmaktayız. PPS sonrası gerilemeyen perikardiyal efüzyonların, dirençli perikarditlerin tedavisinde invaziv girişlerden önce kolşisinin akılda tutulması gereken etkin, ucuz ve yan etkileri nadir bir tedavi yöntemi olduğunu düşünüyoruz. Kolşisin PPS gelişen hastaların tedavisinde kliniğimizde halen güvenle ve başarıyla kullanılmaktadır.
