Background. Infusion solutions are divided into several groups: crystalloids, colloids (natural and artificial), polyatomic alcohols, special drugs (infusion antibiotics, analgesics, hemostatics). Each solution type has its own complications. Objective. To identify the main complications of infusions and prevention measures. Materials and methods. Analysis of the available literature on this topic. Results and discussion. After the transfusion of 1 liter of 0.9 % NaCl only 275 ml of this solution remains in plasma, and 725 ml passes into the interstitial space, causing edema. In addition, there is a risk of hyperchloraemic acidosis in case of massive transfusions. 0.9 % NaCl is inadequate in its ionic composition, has no reserve alkalinity, deepens hyperosmolar changes, so it is not used as monotherapy in daily practice. It is used as a solvent only. Ringer’s solution is also easily excreted into the interstitial space with the edema formation. It is hyperosmolar, contains a large number of chlorine ions and is excreted by the kidneys, so it should be used with caution in patients with kidney disease. A number of drugs (aminocaproic acid, amphotericin B, blood products, sodium thiopental) are incompatible with Ringer’s solution and Ringer’s lactate. In turn, 5 % glucose solution is ineffective for detoxification, liver cirrhosis and restoring the circulating blood volume in case of blood loss. Glucose infusions can increase the production of carbon dioxide and lactate, increase ischemic damage to the brain and other organs, and promote tissue edema. At present, the routine use of glucose during surgery and in critically ill patients has been completely abandoned. Preparations of polyatomic alcohols can be divided into the preparations of six-atomic alcohols – mannitol (Mannit) and sorbitol (Sorbilact, Reosorbilact) and five-atomic alcohols (xylitol – Xylate, Gluxyl, Lactoxyl) (all of the listed solutions are made by “Yuria-Pharm”). Side effects of mannitol include tachycardia, thrombophlebitis, chest pain, skin rash, dehydration, dyspepsia, fluid and electrolyte balance, and hallucinations. Hypotension is the most common complication of mannitol usage. Reosorbilact is a modern balanced infusion solution. Its effects include the hypovolemia correction, restoration of electrolyte disturbances, normalization of cardiac activity and nerve conduction, increase of alkaline blood reserve and restoration of energy balance. In case of the significant overdose Reosorbilact can cause alkalosis. Contraindications to its administration include alkalosis, cerebral hemorrhage, pulmonary embolism, and 3 grade hypertension. Xylitol is a five-atom alcohol that is rapidly incorporated into the pentose phosphate metaboliс pathway. Its side effects include the allergic reactions, hypertension, nausea, and lactic acidosis. The main disadvantage of hydroxyethyl starch (HES) drugs is the adverse effect on hemostasis (especially in drugs of the first generation). In addition, HES may impair the renal function, so they should be used in the lowest effective dose for the shortest period of time. In addition to complications associated with infusion solutions, there are complications associated with the injection procedure (hematoma, infiltration, thromboembolism, air embolism, and phlebitis). The thorough monitoring is needed to prevent the complications of all stages of infusion therapy. Such parameters as blood pressure, heart rate, blood gas composition, capillary filling time, mental status, and diuresis should be monitored. It is also necessary to carefully examine the composition of prescribed drugs and instructions for their medical use, to control the infusion rate, and to combine different drugs rationally. Conclusions. 1. There are several classes of infusion solutions, and each of them has its own advantages and disadvantages. 2. Reosorbilact is a balanced drug with the minimal risk of side effects. 3. To prevent complications, it is necessary to monitor the basic physiological parameters, to control the infusion rate, and to rationally combine different tools.

Background. Preeclampsia (PE) occurs in 2-8 % of all pregnancies. Every day 210 women die from PE, and neonatal losses are even greater (1380 children per day). Fatal complications of severe PE include cerebral hemorrhage, cerebral edema, pulmonary edema, placental abruption, adrenal hemorrhage, dissecting aortic aneurysm, HELLP syndrome, disseminated intravascular coagulation syndrome. Excessive intravenous fluid infusion is one of the causes of pulmonary edema in PE. Objective. To describe the options of severe PE treatment. Materials and methods. Analysis of literature data on this issue. Results and discussion. The pathogenesis of PE is based on total damage to the vascular endothelium, which leads to an increase in its permeability, including for albumin molecules. Plasma protein loss is accompanied by a drop in oncotic blood pressure and fluid leakage into the interstitial space. Thus, in patients with PE there is an associated disturbance of fluid and electrolyte balance: along with intravascular dehydration there is extravascular hyperhydration. Infusion therapy (IT) allows to overcome this imbalance and to increase the colloid-osmotic pressure. According to modern views, a restricted IT regimen improves the effects of PE treatment. There are two ways to correct this disorder: an increase in oncotic blood pressure due to infusion of albumin (indicated in case of blood albumin levels <25 g/L) and the administration of osmotically active drugs, such as Reosorbilact (“Yuria-Pharm”). The latter option prevents the loss of fluid from the vascular bed and promotes its return to the vessels from the intercellular space. The total fluid volume should be limited to physiological needs, taking into account pathological losses (not more than 1 ml/kg/h). The maximum IT volume should not exceed 800 ml per day. The drugs of choice for IT before delivery are balanced isotonic saline solutions and solutions containing 6 % sorbitol. Fresh-frozen plasma is not recommended for the correction of colloid-oncotic pressure. Influence on the redistribution of fluid in the interstitial space without the introduction of significant volumes of infusion solutions is the main principle of low-volume IT. Recommendations for the administration of Reosorbilact comply with this principle. The low osmolarity of Reosorbilact and its ability to improve the osmotic properties of blood justify the use of this drug in women with PE. Conclusions. 1. PE occurs in 2-8 % of all pregnancies. 2. Excessive intravenous fluid infusion is one of the causes of pulmonary edema in PE. 3. Restricted IT mode improves the consequences of PE treatment. 4. Osmotically active drugs (Reosorbilact) are prescribed for this purpose.

Background. The goals of infusion therapy (IT) include the restoration of adequate tissue perfusion, maintaining the quantity and quality of the body fluid sectors, correction of homeostasis parameters. In addition, IT can be used for parenteral nutrition, reducing the risk of thrombosis and urinary tract infections. Objective. To identify key IT parameters of a cancer patient. Materials and methods. Analysis of the available literature on this topic. Results and discussion. Indications for IT include hypovolemia, cellular and protein deficiency of blood, nutrition disorders, intoxication, disorders of hemostasis, hemorheological properties, fluid and electrolyte balance, acid-base status. Cancer patients often have the listed syndromes. The appropriate infusion volume should not be exceeded, as the hypervolemia is accompanied by edema, multiorgan dysfunction and worsening of the prognosis. On the other hand, dehydration is the most common fluid and electrolyte balance disorder in the elderly. It is an independent predictor of mortality and high healthcare costs. At any IT administration it is necessary to assess the volemia condition, to determine the cause of the deficiency, to choose the optimal solution and infusion rate, to set and to monitor target values. Capillary filling time, heart rate, blood pressure, jugular veins’ condition, skin turgor, pulmonary and cardiac auscultation data, edema control, diuresis rate, and weight changes are used to assess volemia. Peculiarities of the elderly and debilitated patients, which should be taken into account when prescribing IT, include the loss of thirst feeling, deterioration of renal function and worsening of hormonal regulation of fluid and electrolyte balance. Anticancer therapy has a number of side effects, and some of them can be eliminated with the help of IT. The amount of fluid required should be calculated based on physiological needs (30-40 ml/kg/day), deficiency severity and pathological losses (fever, blood loss, polyuria, perspiration, drainage losses). Plasma replacement solutions can be divided into crystalloids (iso- and hypertonic saline, Ringera lactate) and colloids (albumin, solutions of gelatin, dextranes, hydroxyethyl starch). Crystalloids are recommended for short-term interventions, while long-term therapy requires colloids or balanced solutions, as the introduction of unbalanced solutions is accompanied by such risks as hyperchloremia, dilutive acidosis, acute kidney damage, and systemic vasoconstriction. In settings of the chronic inflammation, which often accompanies oncological diseases, the role of thirst as a means of controlling osmolarity changes. Hyperosmolarity may also accompany central diabetes mellitus and tumor metastases to the hypothalamus. Hyperosmolarity leads to the microcirculatory disorders, increased inflammation, cachexia development and multiple organ failure. Another feature of IT in oncology settings is the disruption of tissue energy supply due to nutritional deficiencies and changes in metabolism. Xylitol (Xylate, “Yuria-Pharm”) can be used to eliminate this problem. Xylitol is a five-atom alcohol, which is directly included into the pentose phosphate cycle. The benefits of xylitol include metabolism stabilization in people with diabetes, promotion of slow but stable energy production, antiketogenic properties, improved metabolism of B vitamins, cholekinetic action, and high safety. Xylitol is not used by the tumor cells as an energy substrate. The role of xylitol (Xylate) in IT is to increase the volume of circulating plasma, to reduce the interstitial edema, to decrease the production of ketone bodies, to activate the antioxidant systems, and to increase alkaline blood reserve. It has been reported that xylitol infusion has an oncosuppressive effect due to its antioxidant effect and inhibition of glucose utilization by tumor cells. Conclusions. 1. IT is an important component of cancer treatment; it should be based on the individual features of the patient. 2. Rational IT eliminates chronic inflammation, endothelial dysfunction and microcirculatory disorders. 3. Rational IT is based on the correct choice of solution, its timely introduction and frequent evaluation of the infusion response. 4. Xylate (“Yuria-Pharm”) has a multifunctional effect in oncology: eliminates dehydration, corrects energy deficiency, and has a direct oncosuppressive effect.

Background. Infusion therapy (IT) is a method of managing the functions of the organism by influencing purposefully the morphological composition and physiological properties of blood through parenteral administration of organic and inorganic solutions. The main feature of IT is that the drug completely enters the bloodstream. Objective. To describe the main characteristics of fluid and electrolyte balance and the IT principles. Materials and methods. Analysis of the literature sources on this topic. Results and discussion. Fluid comprises about 60 % of the human body (in children – 70-80 %, in adults – 60 %, in elderly – 50-55 %). Total fluid includes intracellular and extracellular. The latter, in turn, is divided into intravascular, interstitial and transcellular. Water balance involves the balance of fluid entering the body and the fluid being excreted. The main sources of water are beverages and food, however, about 300 ml per day is formed endogenously during oxidation processes. The main ways of the fluid excretion are its excretion in urine and stool, and perspiration losses. To calculate the physiological need of water for an adult, the body weight should be multiplied by the coefficient of 30 (up to 65 years), 25 (65-75 years) or 20 (more than 75 years). IT should also take into account the pathological losses of water from fever, vomiting, diarrhea, the presence of large wounds or burns, as well as reduction of the need in water in renal or heart failure. Thus, physiological needs, fluid deficiency, fluid volume as a result of pathological loss should be added, and the oral rehydration subtracted from this sum to calculate IT volume. There are 3 degrees of dehydration severity: I degree – deficiency of 1-2 liters, thirst, oliguria; II degree – deficiency of 4-5 liters, thirst, oliguria, dry skin, mucous membranes and tongue, general weakness; III degree – deficiency of 7-8 liters, consciousness disorders, decrease in arterial pressure, shock. The first degree can be overcome by oral rehydration, the second degree – by 50 % of oral rehydration and 50 % of IT, the third degree – by 70-100 % of IT. IT solutions are divided into crystalloids, colloids, polyatomic alcohols and special drugs. Preparations of polyatomic alcohols include, in particular, Reosorbilact, Sorbilact, Xylate (“Yuria-Pharm”). Complications of IT are divided into complications associated with the violation of the technique of entering the bloodstream (injuries of blood vessels and adjacent organs, hematomas, foreign bodies in the vessels and heart, the solution misplacement out of the vascular space); complications associated with the violation of the technique of drug administration (thromboembolism, air and fat embolism); complications associated with the wrong rate of solutions’ administration (heart overload, hypervolemia, pulmonary edema, cerebral edema); complications associated with the characteristics of infusion solutions (partial hemolysis of blood cells, acid-base imbalance, disorders of blood osmolarity, local cooling of the heart); complications associated with the IT method; complications due to individual intolerance; infectious complications in case of violation of asepsis and antiseptics; infectious diseases. Criteria for IT security include the knowledge of the drug composition and understanding of the instructions for its use; multicomponentity; use of the minimum effective doses; monitoring of the excreted urine and other fluids and infused solutions; strict control of fluid balance and blood circulation parameters. Conclusions. 1. IT is an important tool in treatment of many diseases, which performs a wide range of tasks. 2. The IT solution should be chosen depending on the individual needs of the patient. 3. Criteria for IT safety include the knowledge of drug composition and instructions for its use; multicomponentity; use of the minimum effective doses; monitoring of excreted urine and infused solutions; control of fluid balance and blood circulation parameters.

Drug side effects have become an important indicator for evaluating the safety of drugs. There are two main factors in the frequent occurrence of drug safety problems; on the one hand, the clinical understanding of drug side effects is insufficient, leading to frequent adverse drug reactions, while on the other hand, due to the long-term period and complexity of clinical trials, side effects of approved drugs on the market cannot be reported in a timely manner. Therefore, many researchers have focused on developing methods to identify drug side effects. In this review, we summarize the methods of identifying drug side effects and common databases in this field. We classified methods of identifying side effects into four categories: biological experimental, machine learning, text mining and network methods. We point out the key points of each kind of method. In addition, we also explain the advantages and disadvantages of each method. Finally, we propose future research directions.

Keloids are a benign fibroproliferative disease with a high tendency of recurrence. Keloids cause functional impairment, disfigurement, pruritus, and low quality of life. Many therapeutic options have been used for keloids. However, the high recurrence rates have led to the use of adjuvant therapy after surgical keloid excision. There are different radiotherapy regimens available, and the advantages and disadvantages of each are still unclear. The aim of this review is to explain the appropriate radiotherapy regimen for keloids as well as discuss the recent reports on keloid management with radiotherapy. Adjuvant radiotherapy after surgical excision for keloids yields excellent local control with tolerable side effects. Hypofractionated radiotherapy with a BED of more than 28 Gy (α/β value of 10) after excision is recommended in the light of its biologic background.

: The present review was carried out to describe publications on the use of methylene blue (MB) in pediatrics and neonatology, discussing dose, infusion rate, action characteristics and possible benefits for a pediatric patient group. The research was performed on the data sources PubMed, BioMed Central, and Embase (updated on Aug 31, 2020) by two independent investigators. The selected articles included human studies that evaluated MB use in pediatric or neonatal patients with vasoplegia due to any cause, regardless of the applied methodology. The MB use and 0 to18-years-old patients with vasodilatory shock were the adopted criteria. Exclusion criteria were the use of MB in patients without vasoplegia and patients ≥ 18-years-old. The primary endpoint was the increase in mean arterial pressure (MAP). Side effects and dose were also evaluated. Eleven studies were found of which 10 were case reports and 1 was a randomized clinical study. Only two of these studies were with neonatal patients (less than 28 days-old), reporting a small number of cases (1 and 6). All studies described positive action of MB on MAP, allowing the decrease of vasoactive amines in several of them. No severe side effects or death related to the use of the medication was reported. The maximum dose used was 2 mg/kg, but there was no consensus on the infusion rate and drug administration timing. Finally, no theoretical or experimental basis sustains the decision to avoid MB in children claiming it can cause pulmonary hypertension. The same goes for the concern of a possible deleterious effect on inflammatory distress syndrome.

The objective of our analysis has been to find out and elaborate on why some countries could not benefit from remittance inflows sent by migrants or even are getting into traps due to them. In the authors’ view, the remittance trap may be appraised, notably in the long run, as the dilemma in which a country finds itself when the high value of migrant remittance inflows leads to a high value of human and financial capital outflows, as well as to the moral hazard problem of the country's population and government. Accordingly, remittance trap negatively affects the sustainable growth and development of the economy which eventually deepens the country's dependence on remittances, proving the vicious nature of the trap. Furthermore, the paper focuses on identifying a competent set of policy recommendations for the countries that are remittance dependent. A natural conclusion of our research is that there is a thin line between remittances’ advantages and disadvantages, since in fact, short-term benefits very often turn out into long-run side effects, mainly as a result of mismanagement of remittance inflows, which correlates with unfavourable business climate and decreased willingness of the population to invest. Accordingly, the benefits and adverse side effects of remittance inflows are interdependent.

The article is devoted to prevalence, contemporary diagnostic methods and treatment of Grave’s disease. Advantages and disadvantages of different treatment options are discussed. The cause of the disease can be environmental conditions, infectious diseases, severe operational intervention, drugs, trauma, especially brain traumas, iodine deficiency and radiation damage of thyroid in iodine deficiency conditions, familial predisposition. The ideal treatment of Graves’ disease should ensure a fairly rapid elimination of clinical symptoms of thyrotoxicosis, return to an euthyroid state, with minimal risk of complications. The relapse rate of the disease can reach up to 80 %, using conservative treatment. The radioiodine ablation is relatively simple, non-invasive, effective and cheap. There are special indications for surgical treatment. Indications for surgical treatment: 1) large goiter (the volume of the thyroid gland is more than 45 ml); 2) frequent recurrences of thyrotoxicosis and failure of the drug and RIT; 3)malignancy of goiter; 4) allergic and toxic (leukopenic) reactions to thyreostatics. Patients with Graves’ disease should referred to a specialized center with multidisciplinary team.

Background: Mu agonists have been an important component of pain treatment for thousands of years. The usual pharmacokinetic parameters (half-life, clearance, volume of distribution) of opioids have been known for some time. However, the metabolism has, until recently, been poorly understood, and there has been recent interest in the role of metabolites in modifying the pharmacodynamic response in patients, in both analgesia and adverse effects. A number of opioids are available for clinical use, including morphine, hydromorphone, levorphanol, oxycodone, and fentanyl. Advantages and disadvantages of various opioids in the management of chronic pain are discussed. Objective: This review looks at the structure, chemistry, and metabolism of opioids in an effort to better understand the side effects, drug interactions, and the individual responses of patients receiving opioids for the treatment of intractable pain. Conclusion: Mu receptor agonists and agonist-antagonists have been used throughout recent medical history for the control of pain and for the treatment of opiate induced side effects and even opiate withdrawal syndromes. Key words: Opioid metabolism, opioid interactions, morphine, codeine, hydrocodone, oxycodone, hydromorphone, methadone, intractable pain, endorphins, enkephalins, dynorphins, narcotics, pharmacology, propoxyphene, fentanyl, oxymorphone, tramadol

Introduction: Trichomonas vaginalis is a protozoan parasite that infects the urogenital tract of men and women and causes trichomoniasis, a common sexually transmitted disease in both men and women. The infection is often asymptomatic, but it can be accompanied by symptoms such as severe inflammation, itching and burning, foamy discharge and foul-smelling mucus. In one year, 250 million cases of Trichomonas vaginalis were reported worldwide. Material and Methods: In this study, the websites of PubMed, Google Scholar, SID, and Margiran were searched and related articles were reviewed.    Results: Today, the most common treatment for this disease is the use of metronidazole. However, its side effects, which include hematological and neurotoxic effects, cannot be ignored. Because of these side effects, researchers are looking for a suitable replacement for metronidazole in the treatment of trichomoniasis. Researchers' desire to use  herbs can be due to various reasons such as fewer side effects, better patient acceptance, recommendation of traditional medicine, lower prices of herbs and also compatibility with the normal physiological function of the human body. Conclusion: Considering the inhibitory effects of medicinal plants on the growth and proliferation of Trichomonas vaginalis in vitro, it can be concluded that the use of these plants can have many applications in the treatment of trichomoniasis. As a result, by studying more about their advantages and disadvantages, it is possible to make a drug that has higher therapeutic effects with fewer side effects.
