Cecum Cancer

Coloncancer is one of the first places in the structure of oncological diseases. According to statistics, edited by A.D. Kaprin, V.V. Starinskii, G.V. Petrova ofRussiafor 2015 was initially 36494 case of colorectal cancer, while 2% of cases are not diagnosed. Recurrence of colon cancer can occur at any stage regardless of the time elapsed after the radical treatment. Locoregionally originally is the presence of a tumor in the area of primary operation, which is represented by the primary tumor bed, the anastomosis, mesentery of the colon with lymphatic system, peritoneum and adjacent organs. Often after a diagnosis of “recurrence of the tumor in the colon” to the patient it is possible to provide only palliative care (colostomy, chemotherapy). The article cited clinical observation, confirming the important role of radiation techniques in determination of tactics of treatment of locoregional recurrence of the cecum cancer.

The aim of the work was to study the clinical case of systemic amyloidosis.Materials and methods. Patient Ch., 63 уears old, have admitted to the regional cardiological dispensary with complaints of short stabbing pains in the heart, without reaction to nitroglycerin, interruptions in the work of the heart, mainly at night, shortness of breath with little exertion, weakness, swelling of the legs and feet in September 2018. Sick from April 2016, when was dyspnea on exertion. The high level of creatinine, normochromic anemia have detected. In June 2016 chronic pyelonephritis was diagnosed. In August 2018, a right-sided hydrothorax was diagnosed, a pleural puncture was performed.Results. Laboratory and instrumental research methods were performed. Based on anamnesis data (normochromic anemia, proteinuria, increased creatinine in the blood), clinical picture, data of instrumental studies (restrictive cardiomyopathy, bilateral hydrothorax) clinical diagnosis was made: systemic amyloidosis the kidneys and heart with chronic kidney disease C5 and chronic heart failure. Histological evidence of amyloid and determination of the variant of amyloidosis by immunohistochemical method was recommended. But the patient died before the study. The histological verification of the diagnosis was carried out at the autopsy.Conclusion. This clinical observation is an example of late diagnosis of systemic amyloidosis and postmortal verification of the diagnosis, which is associated with the nonspecific symptoms and the rapidly progressing course of the disease. This case is interesting because amyloidosis proceeded under the guise of other diseases, quickly led to the development of severe heart and renal failure and to the death of the patient before verifying the disease.

Lymphoma is the most common type of blood cancer today and, as its name suggests, it begins in the lymphatic system. The origin of this disease is related to mitochondrial defects, generated by mutations in the PNPase enzyme or polynucleotide phosphorylase, whose main functions are to import and degradation mitochondrial RNA. For this reason, the main objective of the present work was to carry out a bibliographic review of scientific publications that made the role of this enzyme relevant, in relation to mitochondria as the cause of lymphatic cancer. The methodology used consisted of a bibliometric analysis based on the use of different databases, in which search equations formed from keywords were introduced. Then, the selection of articles related to the study topic and published in the last 20 years was carried out. Subsequently, the journals were analyzed, based on the H index, in order to observe which supported the hypothesis of the role of PNPase in lymphoma and which stated the opposite. The results showed that a total of 441,288 scientific publications were obtained, of which 133 were selected to carry out this work. As for the journals, those with the highest H index were Nature and Cell. It can be concluded that PNPase plays a very important role in the transport of mitochondrial RNA, and that the factor NF-Y is involved in the control of cell growth, therefore, both have a crucial role in the development of this disease. Therefore, research on both PNPase and NF-Y is essential to establish the specific genetic characteristics that define the early lesions of lymphatic cancer and the consequent determination of their treatment.

The role of glycoconjugates in tumor cell differentiation has been well documented. We have examined the expression of the two anomers of the Thomsen-Friedenreich antigen on the surface of human, canine and murine tumor cell membranes both in vitro and in vivo. This has been accomplished through the synthesis of the disaccharide terminal residues in both a and ß configuration. Both entities were used to generate murine monoclonal antibodies which recognized the carbohydrate determinants. The determination of fine specificities of these antibodies was effected by means of cellular uptake, immunohistopathology and immunoscintigraphy. Examination of pathological specimens of human and canine tumor tissue indicated that the expressed antigen was in the β configuration. More than 89% of all human carcinomas tested expressed the antigen in the above anomeric form. The combination of synthetic antigens and monoclonal antibodies raised specifically against them provide us with invaluable tools for the study of tumor marker expression in humans and their respective animal tumor models.

It has been suggested that heparin caused potentiation of aggregation induced by ADP or epinephrine. The exact mechanism of heparin-induced platelet activation, however, remained unknown. In this paper, we have investigated the role of anti-thrombin III ( AT ) in heparin-induced platelet activation using purified AT and AT depleted plasma. When ADP or epinephrine was added to citrated PRP one minute after addition of heparin ( 1 u/ml, porcine intestinal mucosal heparin, Sigma Co. USA ), marked enhancement of platelet aggregation was observed, compared with the degree of aggregation in the absence of heparin. However, in platelet suspensions prepared in modified Tyrode’s solution, heparin exhibited no potentiating effect on platelet aggregation induced by epinephrine or ADP. Potentiation of epinephrine- or ADP-induced platelet aggregation by heparin was demonstrated when purified AT was added to platelet suspensions at a concentration of 20 μg/ml. AT depleted plasma, which was prepared by immunosorption using matrix-bound antibodies to AT, retained no AT, while determination of α1-antitrypsinα2- macroglobulin and fibrinogen in AT depleted plasma produced values which corresponded to those of the original plasma when dilution factor was taken into account. The activities of coagulation factors were also comparable to those of the original plasma. Heparin exhibited potentiating effect on ADP- or epinephrine-induced aggregation of platelets in original plasma, but no effect in AT depleted plasma. When purified AT was added back to AT depleted plasma at a concentration of 20 μg/ml, potentiation of platelet aggregation by heparin was clearly demonstrated.Our results suggest that effect of heparin on platelet aggregation is also mediated by anti-thrombin III.

One of the most serious problems of modern medicine is sepsis. The number of patients undergoing this complication is 20–30 million (WHO) annually and has no tendency to decrease. Sepsis is characterized by severe multiple organ failure due to a violation of the response of the macroorganism to an infectious agent. Moreover, it is dangerous with high mortality. Sepsis often develops in patients with immunodeficiency conditions, which primarily include pregnant women. The article presents a clinical observation of a case of periostitis in a pregnant woman complicated by a septic state.

Розвиток проаналізовано як категорію,  явище і проблему психології розвитку в різних аспектах аналізу. Розглянуто місце розвитку в системі  споріднених психологічних понять. У статті також аналізуються психологічні аспекти теоретичних та  методологічних  постнекласичних  тенденцій  вивчення  природи,  характеру  та  визначення  психічного  розвитку. Постнекласична парадигма та плюралістична методологія пізнання визначають розмитість  дисциплінарної мови  та  врахування  ролі  соціокультурного  контексту  при  вивченні  психологічних явищ.  Важливими тенденціями сучасного теоретико-методологічного стану психологічних досліджень розвитку  також є визнання неефективності моністичного підходу до його вивчення, взаємозв'язок теоретичних ідей  та   спроби   створення   метатеоретичних   схем,   постнекласичне   розуміння   розвитку   як   принципово  незавершеного   процесу   саморуху,   актуалізація   антропологічного   діапазону   проблем   та   посилення  спрямованості на роль культурного контексту в дослідженні розвитку людини.  The article deals with the modern approaches to the interpretation of the category of development, reveals  the theoretical and methodological approaches to study of development in modern psychology, its psychological  content, patterns, structure and dynamics. Category of development is viewed as an epicenter of scientific issues in  modern  psychology  and  the  concept  of  the  integrative  type.  Category  of  development  is  considered  as  the  phenomenon  and  the  problem  of  developmental  psychology  in  various  aspects  of  the  analysis.  Analyzed  the  development site in the related psychological concepts. The article analyzes the psychological aspects of theoretical  and methodological postnonclassical contemporary trends in the study of nature, character, and determination of  mental  development.  Postnonclassical  paradigm  and  pluralistic  methodology  of  knowledge  determine  the  disciplinary blurring and increase of the role of the analysis of socio-cultural context in the study of psychological  phenomenon. The important tendencies of modern theoretical and methodological state of psychological researches  of development are facts of inefficiency of the monistic approach to its study, interconnection of theoretical ideas  and   attempts   of  creating   metatheoretical   schemes,   postnonclassical   understanding   of   development   as   a  fundamentally  uncompleted  process  of  self-motion,  actualization  of  anthropological  range  of  problems  and  strengthening of focus on the role of cultural context in research of human development.

Background. Currently, vascular access is one of the most important aspects in specific and accompanying treatment of cancer patients regardless of their age and sex. Partially implanted venous catheters previously described by Hickman were widely applied all over the world. The introduction of completely implanted venous port-systems revolutionized health care delivery and improved the quality of life in patients with oncological diseases. A fully implanted venous port consists of a silicone catheter which distal tip is connected to a port tank implanted subcutaneously. Such a design allows providing safe and multiple adequate vascular accesses regardless of the patient’s clinical state.Case Report. We present a clinical case of a 10-year-old patient diagnosed with medulloblastoma of the cerebellopontine angle and the left cerebellar hemisphere. The case described spontaneous detachment of an implanted venous port catheter and its migration to the venous heart in a patient who underwent chemotherapy by venous access provided through implantation of the venous port.Conclusion. Our clinical case demonstrated a rare and potentially extremely dangerous noninfectious complication associated with the use of venous port-systems. Implanted systems require washing 1–2 times per month with heparinized solutions or solutions containing taurolidine when they are not used. Periodic chest radiographs can reveal integrity alterations of the system. Any implanted system should be removed when it is not used, or it should be monitored on a regular basis.
