The purpose of the study is to determine the significance of genetic factors in the development of chronic nephritic syndrome in children and to clarify the features of the clinical course
The оbject of research were 129 children aged 4-15 years who were treated for chronic nephritis in the nephrology department of the Samarkand Regional Multidisciplinary Paediatric Medical Centre.
The scientific novelty of the study is as follows:it has been established that the severity of chronic nephritic syndrome in children is associated with clinical manifestations (gradual development, dyspepsia, abdominal pain) and an increase in the amount of Cystatin C in the blood;for the first time, it was revealed that the development of sclerotic lesions due to increased proliferation in patients with the presence of the MMP-9 (A-8202G) rs 11697325 genotypes in chronic nephritic syndrome leads to a worsening of the clinical course of the disease; established early diagnostic marker MMP-9 (A-8202G) rs 11697325 and its tissue inhibitor TIMP-2 (C536T) rs 11551797 in chronic nephritic syndrome in children in the diagnosis of the disease; for the first time, the prognostic value of the alleles of the MMP-9 (A-8202G) rs 11697325 genes and the homozygous G/G genotype in determining the risk of developing the disease in children with chronic nephritic syndrome has been proven.
Implementation of the research results. Based on scientific results of evaluation of the role of polymorphic genes of matrix metalloproteinase and its tissue inhibitors in chronic nephritic syndrome in children: methodological recommendation “The role of polymorphic genes of matrix metalloproteinase and its genetic inhibitors in the development of chronic nephritic syndrome in children” was developed and approved (reference of the Ministry of Health of the Republic of Uzbekistan No. 8n-r / 554 of 30.02.2022).
This methodological recommendation made it possible to predict the development of chronic nephritic syndrome in children and improve preventive measures; approved and developed on the basis of scientific results of research on early diagnosis and prognosis of chronic nephritic syndrome “Dynamics of clinical and laboratory parameters in nephritic syndrome in children”, (reference of the Ministry of Health of the Republic of Uzbekistan No. 8n-r / 555 of 30.02.2022).
This methodological recommendation made it possible to optimize the diagnosis and treatment tactics for various forms of nephritic syndrome in children;
The results obtained were implemented in the practice of health care, in particular, in the Republican Children's National Medical Center, in the 1st clinic of the Samarkand State Medical University, in the Samarkand Regional Children's Multidisciplinary Medical Center (conclusion No. 8 n-r/324 of 21.06.2022 of the Ministry of Health of Uzbekistan).
The application of the obtained results to practice has made it possible to reduce the frequency of recurrence of the disease in children, prevent complications of the disease, improve the quality of life of patients, diagnose and prevent the disease.

In children’s tuberculosis inpatient departments of the PMCforPhandP and the Tashkent city tuberculosis hospital, 272 children and adolescents with various forms of tuberculosis were examined. Among children with various forms of tuberculosis, 28(10,3%) patients were diagnosed with complicated forms and 244 (89,7%)-uncomplicated forms of tuberculosis. When studying the risk factors for the disease, it was revealed that there were 225 (87,7%) children vaccinated with BCG, of which 58 (25,8%) children (76,8%), of whom anemia was found in 35 (12,9%) patients. In the structure of clinical forms in childrenand adolescents with tuberculosis, tuberculosis of the intrathoracic lymph nodes (57,0%) and primary tuberculosis complex (11,0%) predominate. Most of the children hada positivity to tuberculin (77,5±2,5%) and to the test for Diaskintest (69,5±2,7%).
По данным Всемирной организации здравоохранения, в последние годы наблюдается рост заболеваемости острой респираторной вирусной инфекцией. В связи с этим внимание педиатров и отоларингологов привлекают острые стенозирующие ларинготрахеиты (ОСЛТ). Согласно данным многолетних исследований, число пациентов с ОСЛТ колеблется от 0,1 до 0,4% от всех госпитализированных в стационар детей с диагнозом «острая респираторная вирусная инфекция». Развитие стенозирующего ларинготрахеита при острой респираторной вирусной инфекции (ОРВИ) резко отягощает состояние больных детей, а порой от присоединения его к основному заболеванию зависит жизнь ребенка.
С первых дней независимости в нашей стране с целью повышения качества медицинской помощи населению последовательно реализуются широкомасштабные реформы. Так, эффективное медицинское обслуживание детей обеспечило своевременное выявление, раннюю диагностику и лечение больных с ОСЛТ, что позволило на 3-4 дня сократить сроки лечения их в стационаре.
Несмотря на многочисленные научные исследования, посвященные изучению закономерностей инфекционного процесса при стенозирующем ларинготрахеите, роли дисбиоцсноза слизистых оболочек верхних дыхательных путей, процесс эндогенной интоксикации (ЭИ), развивающийся в результате болезни детей и его связь с течением заболевания, а также состояние системы местного и общего иммунитета диктуют необходимость совершенствования методов их коррекции в свете современных требований. Вместе с тем, причины рецидивирования острых стенозирующих ларинготрахеитов до конца не определены, важной задачей представляется разработка прогностических критериев оценки исходов ОСЛТ.
Данное диссертационное исследование в определенной степени служит решению задач, предусмотренных в постановлениях Президента Республики Узбекистан № ПП-2133 от 19 февраля 2014 года «О Государственной программе «Год здорового ребенка» и № ПП-2221 от 1 августа 2014 года "О Государственной программе по дальнейшему укреплению репродуктивного здоровья населения, охране здоровья матерей, детей и подростков в Узбекистане на период 2014-2018 годы», а также в других нормативноправовых документах, принятых в данной сфере.
Научные исследования, направленные на совершенствование методов комплексной диагностики, лечения и профилактики стенозирующих ларинготрахеитов у детей проводились во многих ведущих медицинских центрах, таких как детский медицинский центр Шнайдера (Израиль), Университетская клиника Гиссена (Германия), Детская клиника Святой Марии (Германия), Центр инновационной медицины Интербалкан (Греция), клиника Женераль (Швейцария), клиника Роял (Великобритания), Медицинский центр Куинс (Великобритания), клиника ИДИБАПС (Испания), госпиталь Святого Луки (Япония), Федеральный научноклинический центр оториноларингологии ФМБА России (Россия), а также Ташкентский педиатрический медицинский институт и Республиканский специализированный научно-практический медицинский центр педиатрии (Узбекистан).
В результате проведенных исследований были разработаны критерии оценки риска возникновения и рецидивирующего течения ОСЛТ, выявлены механизмы, определяющие чувствительность дыхательных путей (Фрейбург-ская клиника, Германия); установлена эндокринная дисфункция у детей с первичной и рецидивирующей формой острого стенозирующего ларинготрахеита (Детский госпиталь, Ирландия); доказано влияние состава микрофлоры основных локусов организма, соединительнотканной дисплазии, регулирующих систем на функцию внешнего дыхания, формирование пороговой чув-
ствительности и реактивности дыхательных путей у детей с рецидивирующим стенозирующим ларинготрахеитом (РСЛТ) (Мельбурнский университет, Австралия).
В настоящее время в мире целью многих исследований становится дальнейшее определение на иммуномолекулярном уровне роли специфических и неспецифических факторов иммунной защиты в патогенезе острого стенозирующего ларинготрахеита; оценка состояния неспецифической защиты при ОСЛТ; изучение достоверных сдвигов в клеточном звене иммунитета, изменений Т-супрессоров и частично В-лимфоцитов; а также профилактика рецидивов и совершенствование методов диагностики и лечения заболевания.
Как показал анализ специальной литературы, ряд исследователей изучали роль аллергического компонента и вегетативной нервной системы в патогенезе развития первичных и рецидивирующих ОСЛТ. Согласно полученным результатам, более чем у 90% больных детей в патогенезе первичного и рецидивирующего острого стенозирующего ларинготрахеита преобладает аллергический компонент с выявлением общих и аллергенспецифических IgE. Кроме того, доказано, что развитие ОСЛТ при парагриппозной инфекции связано с существенным повышением титра IgE и специфического IgA в назофарингеальных секретах у детей с ОРВИ. Изучены механизмы рециди-вирования ОСЛТ, основанные на значительном изменении иммунологической реактивности организма, которые связаны с его аллергизацией как инфекционными, так и неинфекционными агентами, включая неблагоприятные экологические, сезонные, метеорологические и даже социальные условия. Доказано, что ОСЛТ протекает с вегетативными расстройствами, которые, в свою очередь, оказывают существенное влияние на течение и исход основного заболевания. Предложено усовершенствованное лечение ОСЛТ в разгар заболевания, основанное на применении лекарственных препаратов с учетом типа исходного вегетативного тонуса организма.
Несмотря на многочисленные работы, посвященные изучению острого стенозирующего ларинготрахеита, ее диагностике и методам лечения, тенденция к росту рецидивирования заболевания сохраняется, что диктует необходимость изучения общих закономерностей инфекционного процесса при стенозирующем ларинготрахеите, оценки значения микробиоценоза слизистых оболочек верхних отделов респираторного тракта, нарушений иммунного и интерфероновых статусов и разработки способов их коррекции, прогнозирования заболевания на основе прогностической карты, а также повышения эффективности лечения и профилактических мероприятий.
For parents, a child of any age seems vulnerable, so adults take care of him, they want protection from all difficulties. Unfortunately, a person is not strong and some diseases are very dangerous for the life of children. Some pathologies pass quickly and affect the future life, otherwise others will significantly affect the future life of the child. In order to reduce the impact of pathologies on the child's body, it is possible to diagnose the disease in the early stages, it is necessary to identify and immediately begin treatment. Among these diseases are ophthalmic we can not do without the introduction of diseases. If a child has vision problems from an early age, it can lead to a delay in the development of the child in the future. Ophthalmic diseases the main part: eye injuries, glaucoma, cataracts, glaucoma, retinopathy, myopia, cataract diseases, etc. More than 20% of diseases in ophthalmological practice, depending on the injury, damage the orbit and the eyeball. From an eye injury, then in 13% of cases, subatrophy of the eye develops, in 25% anophthalmos may occur. As for the characteristics of injuries, 10% of children suffer from damage to the organ of vision. This leads to various pathologies of the eye, in 30-60% of cases it can lead to one- or two-sided blindness. The most important traumatic factors in children are: knives, bullets, stones and clubs, hockey sticks, spears, nails, wire, etc. Glaucoma is one of these diseases. The disease also requires special attention. Reason: Prevalence of glaucoma in children Occurs in 1:10,000-1:12,000 cases. Its share in eye pathology is 0.1%. enough. More than 75% of glaucoma cases are bilateral. In parallel, there was glaucoma in 5 to 15% among children, blind and non-blind schoolchildren. Blindness in children, the proportion of this pathology ranges from 2 to 15%. in the Russian Federation Congenital glaucoma accounts for 10.1% of childhood blindness.
The aim of the research work is to improve the results of surgical treatment of chronic anterior-medial dislocations of the radial head in children based on the improvement of the method of surgical treatment.
The object of the study was 83 patients with chronic antero-medial dislocations of the head of the radius, treated in the department of the consequences of childhood injuries of the Samarkand branch of the RSSPMC of Traumatology and Orthopedics for the period 2017-2020. The scientific novelty of the research work is the following: it is proved by histological examination that, in case of injuries from up to 1 month ago, the anterior wall of the joint capsule is thin and elastic, which is easily stretched, and from 3 months ago, it thickens, scars and forms fibrous tissue; the possibility of using a fibrous-modified joint capsule for annular ligament plasty in the surgical treatment of chronic antero-medial dislocations of the radial head from 3 months ago was proved; the tactics of surgical treatment of chronic antero-medial dislocations of the head of the radius depending on the deformity of the bones of the forearm were determined; a direct relationship between the results of surgical treatment of chronic antero-medial dislocations of the head of the radius, depending on the duration of the injury, has been proven.
The introduction of research results. Based on the obtained scientific results on the optimization of surgical treatment of chronic antero-medial dislocations of the radial head in children:
based on the results of the development of a method for annular ligament plasty, a patent for an invention was obtained from the Intellectual Property Agency of the Russian Federation “A method for the surgical treatment of chronic anterior medial dislocation of the radial head in children by capsuloplasty according” (patent № 2749870 dated 06/17/2021). The results obtained made it possible to improve the results of surgical treatment, to reduce the period of penetration in the hospital and after the surgical rehabilitation period; based on the results of scientific research on the surgical treatment of chronic anterior medial dislocations of the radial head, the guidelines “Surgical treatment of chronic dislocations of the radial head in children” were approved (Conclusion of the Ministry of Health of the Republic of Uzbekistan 8 n-z / 81 dated February 21, 2022). The results obtained have improved the quality of early diagnosis and treatment of patients with chronic anterior medial dislocations of the radial head in children; based on the results of scientific research on the surgical treatment of chronic antero-medial dislocations of the head of the radius, the methodological recommendations “Conclusion of the Ministry of Health of the Republic of Uzbekistan 8 n-z / 289 of August 31, 2021” were approved.

The purpose of the study was to improve the quality of anesthesia during orthopedic operations in children using the opioid-sparing anesthesia technique.
Materials and methods. The course of anesthesia was analyzed in 48 patients aged 3 to 14 years, during orthopedic operations in children. The distribution of patients into groups was carried out depending on the technique of anesthesia. Group 1 (main) consisted of 25 children who underwent general anesthesia using low doses of fentanyl, sevoflurane and propofol. group 2 (control) - 23 children who underwent general anesthesia with fentanyl and propofol. Echocardiography was used to determine hemodynamic parameters. The dynamics of changes in the level of cortisol in the blood and the concentration of catecholamines (adrenaline, norepinephrine, dopamine) in daily urine was studied. Results. In children of the first group, during the introductory period of anesthesia, there was a decrease in CI, an increase in heart rate and UPS. Stroke index (SI), mean arterial pressure (MAP), cardiac index (CI) changed insignificantly compared to the previous stage of the study. In the children of the second group in the most traumatic stages of the operation, there was an increase in SI, HR, and AI. In the most traumatic stages of the operation and after the operation in children of the first group, there was a tendency to increase cortisol, in the second group of patients, an increase in cortisol was noted.
The frequency of preterm birth is variable, but in most developed countries in recent decades it has been quite stable and amounts to 5-10% of the number of children born[18,29,35]. The frequency of adverse outcomes among surviving children born before 28 weeks of gestation reaches 40–50%, rising to 70–90% for children weighing 500.0–750.0 g[30,32,34,36]. In children born with low body weight, mortality reaches 30% [8,30]. The current level of development of perinatology makes it possible to increase the survival of these children, but the peculiarities of their subsequent growth and development require no less attention. [8]. The fact of premature birth of children in women with a burdened obstetric-gynecological and somatic history is associated with perinatal CNS damage and often with a change in the vegetative status of a child in the first years of life. [9,37,41]. In early childhood and in subsequent periods of development, these children show psychosomatic abnormalities, in particular nocturnal enuresis, prolonged low-grade fever, tics and obsessive movements, attention deficit hyperactivity disorder, tension
cephalalgia, arterial hypertension, arterial hypotension, biliary dyskinesia, bronchial asthma, atopic dermatitis[27,39]. An inverse relationship has been shown between low birth weight and adult blood pressure levels, the likelihood of developing type 2 diabetes, cardiovascular disease, and an excessive response to stress [26,38]. Lack of motor development in children at 16 years of age is associated with body weight less than 2 kg at birth. [31]. IQ tests showed that 41% of children born at the 7th month of pregnancy had worse performance compared to their healthy peers and had learning problems [41]. Early preterm birth can negatively affect puberty and increase the chance of adolescent depression [16], as these children may slow down the process of myelination of the frontal lobe of the brain, which is responsible for motivation, satisfaction, short-term memory and vision. [35]. Studies conducted among adolescents born prematurely revealed anomalies in their brain development, namely, a lack of gray matter in the temporal brain and cerebellum [37].
