Vulvar lichen sclerosus (VLS) is a chronic inflammatory dermatosis, which is characterized by focal skin atrophy of the vulva and mucous membranes. It leads to deformation of the perineum. The prevalence of VLS in children is up to 0.1%, among the adults — 3%. The average age of the first symptoms appearance in girls is 5.4 years, in women — 55.1 years. The diagnosis of VLS is made on the base of anamnesis, assessment of pubertal development, physical examination of the external genitalia, advanced vulvoscopy and vaginoscopy, bacteriological, bacterioscopic and cytological studies of vaginal wet mount, assessment of the hormonal profile. The treatment methods include high-potency steroids as the initial treatment, usage of diode, fractional CO2 and erbium lasers with different wavelengths and injections of platelet-rich plasma to improve the regeneration processes of the affected tissue by improving collagenogenesis, vasculogenesis, production of proteoglycans and glycoproteins. \u0000The aim of the study is to compare the effectiveness of photodestruction with a manual diode laser of the Dornier Medilas D LiteBeam, wavelength of 940 nm, minimum power in pulsed mode on the girls’ vulva mucosa with various types of VLS during neutral and preadolescent age. To obtain the results there were analyzed criteria including the size of the lesion after photodestruction therapy, the disappearance of cracks and angiomatosis in the LS area. The objectives of the complex therapy of VLS in girls were elimination of itching, decrease of the inflammatory changes, improvement of the skin and mucosa blood supply, and stimulation of local immunological mechanisms. \u0000Materials and methods. The study was conducted on the base of the gynecological department of Russian Children’s Clinical Hospital. The effectiveness of the laser-induced thermotherapy with a wavelength of 940 nm, minimum power in pulsed mode on the vulva of VLS girls of neutral and preadolescent periods as a part of the complex therapy was evaluated. Ninety 5 to 13 year VLS patients took part in the trial. They were divided into 3 groups. The first group included 30 patients (average age 7.5 ± 1.1) with atrophic form of lichen treated with a laser with a wavelength of 940 nm. The second group consisted of 30 patients (average age 6.8 ± 1.3) with erythematous-edematous lichen, who were treated with a laser with a wavelength of 635 nm. The third group included 30 patients (average age 7.3 ± 1.2) with erosive and ulcerative form of VLS, who received high-potency corticosteroids therapy. \u0000Results. The treatment results in the three subgroups of VLS patients show a diode laser with a wavelength of 940 nm therapy to be the most effective. After the first treatment course 27 (90%) patients in the first group showed a positive trend with a decrease in itching and burning, pink-color presence in vulva mucousа, a decrease of the skin pigmentation area and an increase in the elasticity of the skin.

Despite the achievements of modern multimodal risk-adapted therapy, the prognosis in patients with high-risk NB remains unfavorable. Numerous research groups have shown that a good response achieved at the time of completion of the induction stage of therapy in this subgroup of patients correlates with survival rates. Thus, improving the response to induction therapy may be a potential mechanism for improving long-term survival rates. Over the past few decades, traditional approaches to cancer therapy have undergone a radical revolution, largely due to the development and implementation of the immunotherapy method. It is known that combined antitumor therapy is superior to monotherapy and is one of the tools for overcoming heterogeneous drug resistance. A vast number of preclinical studies has shown that GD2-directed monoclonal antibodies (mAbs) are able to enhance the cytostatic effects of chemotherapeutic drugs, which has become a promising model for clinical studies of various chemoimmunotherapy regimens, which have demonstrated convincing evidence of safety and an acceptable toxicity profile with an encouraging effect on objective response rates, overall and event-free survival in both patients with recurrent, refractory NB, and primary patients of the high-risk group.The article discusses fundamental ideas about the synergistic interaction of GD2-directed mAbs in combination with cytostatic agents, the role of response to the induction stage of therapy and prospects for the use of induction chemoimmunotherapy as a method of improving postinduction response, event-free and overall survival in patients with NB.","PeriodicalId":52396,"journal":{"name":"Russian Journal of Pediatric Hematology and Oncology","volume":"142 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86744671","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Liver tumors account for 1.1 % of all newly diagnosed neoplasms in children. The rarity of this pathology causes difficulties in differential diagnosis. Currently, magnetic resonance imaging (MRI) is the main and most promising method for diagnosing liver diseases. In our work, we decided to quantify the data from this study.Purpose of the study – determination of the possibilities of quantitative assessment of multiparametric MRI data in the differential diagnosis of benign and malignant liver tumors in children.Material and methods. 133 patients with 307 liver lesions aged from 5 months to 20 years were examined. All patients underwent MRI on high-field MRI machines using an extracellular contrast agent, which included T2 weighted images with and without suppression of the signal from adipose tissue, diffusion-weighted images with automatic calculation of maps of the apparent diffusion coefficient (ADC), T1 weighted images with suppression of the signal from adipose tissue before and after the introduction of a contrast agent (in the arterial, portal, venous and delayed phases). Quantitative characteristics of changes in signal intensity in the lesion, intact liver parenchyma, spleen, kidney, aorta, and inferior vena cava (IVC) were obtained. To level the influence of external factors, we used not the absolute values of the signal intensity, but the ratios: lesion/intact liver parenchyma, lesion/kidney, lesion/aorta, lesion/spleen, lesion/IVC. For each lesion, 5 coefficients were calculated in each of the sequences, with the exception of patients (n = 4) after splenectomy, in whom 4 coefficients were calculated. In addition, for images obtained after the injection of a contrast agent, the ratios of the signal on post-contrast images to the native phase were calculated. Quantitative parameters such as the maximum size of the tumor, its volume and the age of the patient were included in the calculation. Tumors were represented by benign (n = 139) and malignant (n = 169) formations. The diagnosis of all malignant neoplasms and some benign ones was confirmed morphologically, benign ones – using MRI with intravenous contrast and dynamic observation.Results. A mathematical model was built:A = 1/(1+e-Z),where Z = 6,25019 + 1,03132 × S + 1,30077 × P2le/li – 0,00459 × DCle + 4,01375 × P1le/a – 2,05533 × Part le/li – 2,55823 × Pport le/k + 7,56980 × Pdel5 le/k – 15,91047 × Pdel5 le/a.The model is informative and statistically significant (p < 0.001). If A > 0.5, it should be considered that the studied focus is of a malignant nature, if A ≤ 0.5, the formation is benign. Model sensitivity and specificity were, respectively, 0.947 and 0.917.Conclusion. The mathematical model makes it possible to differentiate between malignant and benign formations with a high degree of informativeness, which is a priority task in detecting a mass formation in the liver.","PeriodicalId":52396,"journal":{"name":"Russian Journal of Pediatric Hematology and Oncology","volume":"201 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80154428","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Malignant tumors among the children’s population is a relatively rare phenomenon. In the USSR, the form of state reporting for the analysis of morbidity provided for the collection of data in the first age group totaling from 0 to 29 years. Indeed, in this age group, malignant tumors are rare 10–15 cases per 100,000 children. Then, after the 35-year-old group, the risk of cancer increases by 10 % every year, and a five-year period gives an increase in the incidence rate by 50–70 %. The probability of malignant tumors in younger age groups differs hundreds of times from those who have reached the age of 70. In accordance with World Health Organization – IARC recommendations, the data in IARC monographs are summarized for 5-year-old age groups 0–4, 5–9, 10–14, 15–19, etc. The last open interval is 85+.Prepared by the staff of the Laboratory of Oncological Statistics and the Children’s Department of the N.N. Petrov National Medical Research Center of Oncology together with Novel LLC, the completed topic of scientific development of the population children’s cancer registry at the federal district level, transmitted and accepted by the Ministry of Health of the Russian Federation, turned out to be unclaimed.In February 2019, we formed a unified database of the Northwestern Federal District with a volume of more than 1 million 350 thousand observations, which made it possible to carry out a more detailed development of data on rare localizations: cancer of the heart, eye, thymus, including rare tumors that occur among children population (0–14 years old) and adolescents (15–17 years old). The purpose of the study is to study the patterns of dynamics of morbidity, mortality, the reliability of accounting for sick children (0–14 years old) at the population level, to calculate the survival rates of patients with all tumor localizations, taking into account gender, age, stage of the disease, histological forms and other parameters included in the registration form card (in accordance with the international standard of the Eurocare program). Results. From 2000 to 2018, 4970 children (0–14 years old) with malignant tumors were registered in the Northwestern Federal District of the Russian Federation, of which 3011 are subject to the staging of the tumor process. It is important to note that among all children of patients with malignant tumors, the five-year survival rate of stageable and non-stageable patients was close to 80 %. There is a high level of staging of patients of this group. Thus, patients with stage I of the disease had a five-year survival rate (2010–2014) – 96.3 %, with II – 91.0 % and only with stage IV – 50.9 %.Conclusions. The creation of a children’s population cancer registry at the federal district level could significantly raise the level of primary registration of malignant tumors, eliminate losses and be able to calculate analytical indicators for rare childhood localization of malignant tumors.","PeriodicalId":52396,"journal":{"name":"Russian Journal of Pediatric Hematology and Oncology","volume":"63 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73143605","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
