The objective: to evaluate the effectiveness of neurometabolic therapy in patients with severe course of the new coronavirus infection of COVID-19 complicated by the development of encephalopathy.Subjects and Methods. A pilot prospective study was carried out with the participation of 61 patients with a severe course of COVID-19 complicated by encephalopathy. The patients were randomized into two groups: the study group (n = 34), the patients in which, in contrast to the control group (n = 27), received Cytoflavin in addition to the main therapy in a daily dose of up to 40 ml for 5 days. The dynamics of the general and neurological status was assessed on days 3‒4 and 6‒7 days of treatment using the NEWS (National Early Warning Score), Glasgow coma and ICDSC (Intensive Care Delirium Screening Checklist) scales. Additionally, the blood level of neuron-specific enolase (NSE) was investigated at baseline and on days 6‒7.Results. Patients in most cases were elderly or senile with a high comorbidity index (up to 4 points according to Charlson). The persistence of delirious symptoms correlated with their age and low SpO2 levels. In half of the cases (50.8%), the disease had an unfavorable outcome. In the study group, by the 6‒7th day of treatment, there was a significant positive dynamics of the general condition, assessed by the NEWS scale (p = 0.012), a tendency towards a faster recovery of the overall score on the Glasgow scale (p = 0.083), a tendency towards more rapid regression of delirious symptoms by ICDSC scale (p = 0.055) versus the comparison group.Conclusions. Given the high risk of an unfavorable outcome in patients with a severe course of COVID-19 complicated by the development of encephalopathy, the additional use of Cytoflavin is advisable since it contributes to the regression of the symptoms of encephalopathy and may have a positive effect on the course of the disease.

Purpose — to improve the pathogenetic treatment of pneumonia in children with recurrent acute respiratory infections by combining of protocol therapy with a drug has antioxidant, antihypoxic and organoprotective effects. Materials and methods. The analysis of the results of clinical, laboratory and instrumental methods of examination of children with pneumonia at the age of 3–8 years which have recurrent acute respiratory infections has performed. Children have had received standard protocol treatment of pneumonia and combination with a drug has antioxidant, antihypoxic and organoprotective effects. Results. Optimization the protocol treatment of pneumonia in children with recurrent acute respiratory infections by supplementing pathogenetic therapy with this drug made possible to improve the efficiency of treatment, what confirmed by the rapid regression of clinical manifestations of pneumonia (intoxication — to 1.9±0.04 days, cough — to 2.1±0.08 days, respiratory failure — to 1.7±0.08 days, shortness of breath — to 1.3±0.04 days, disorders of microcirculation and hemodynamics — to 2.1±0.05 and 1.8, respectively ± 0.09 days). This approach calls the decrease of percentage of children with pneumonic infiltration according to the control X-ray examination of the lungs — to 30.0%, myocardial hypoxia according to the ECG results — 20.0%, which made possible to reduce the duration of the course of antibiotic therapy to 2.0±0.04 days, inpatient treatment — to 2.2±0.08 bed-days. The positive dynamics laboratories values, clinical signs and instrumental methods of examination of such children occurred due to an increasing levels of glutathione reductase and glutathione transferase in the blood serum to 4 and 3 times, respectively, and a decreasing the content of glutathione peroxidase and gamma$glutamyl transpeptidase to 2.6 and 1.6 times. Conclusions. Supplement the protocol therapy of pneumonia in children with recurrent acute respiratory infections with a drug has antioxidant, antihypoxic and organoprotective effects promoted a rapid regression of clinical manifestations due to the improvement of the functional activity of the oxidative system of glutathione, which made possible to reduce the duration of the course of antibiotic therapy and inpatient treatment. The research was carried out in accordance with the principles of the Helsinki declaration. The study protocol was approved by the Local ethics committee of all participating institution. The informed consent of the patient was obtained for conducting the studies. No conflict of interest was declared by the author. Key words: children with recurrent acute respiratory infections, pneumonia, treatment.

AbstractIn the COVID-19 pandemic era, anti-SARS-CoV-2 vaccination is considered to be the most efficient way to overtake the COVID-19 scourge. Like all medicines, vaccines are not devoid of risks and can in rare cases cause some various side effects. The objective of this case report is to highlight this unusual presentation of Henoch-Schönlein purpura following an anti-COVID-19 vaccination in a 62-year-old adult. The 62-year-old patient admitted to the emergency room for a petechial purpuric rash, sloping, occurring within hours, involving both legs and ascending. The clinical signs also included polyarthralgia and hematuria. Reported in the history the notion of an anti-COVID-19 vaccination 8 days prior to the onset of symptomatology. In the case of our patient, we retain the diagnosis of rheumatoid purpura based on the EULAR/PRINTO/PReS diagnostic criteria. Corticosteroid therapy (prednisone) was started, resulting to a rapid regression of clinical and laboratory symptoms, few days after the treatment. Patient was asymptomatic on subsequent visits. The low number of published cases of post-vaccine vasculitis does not question the safety of vaccines, but knowledge of such complications deserves to be known in order to avoid new immunizations that could have more serious consequences, and to avoid aggravating or reactivating a pre-existing vasculitis.

Neovascular glaucoma (NVG) is an aggressive type of glaucoma, which often results in poor visual outcomes. Antivascular endothelial growth factor is frequently used for various conditions in which VEGF release is induced in response to retinal ischemia. Bevacizumab is a humanized anti-VEGF monoclonal IgG1 antibody. The potential of antivascular endothelial growth factor (anti-VEGF) agents to modify the disease course of neovascular glaucoma (NVG) was recognized shortly after their use in the treatment of age-related macular degeneration was reported. These medications were noted to induce rapid regression of the anterior segment neovascularization that characterizes NVG. Several studies as well as extensive clinical experience have demonstrated a rapid regression of anterior segment neovascularization following the injection of anti-VEGF agents. This review aims to summarize current evidences regarding effectiveness of Bevacizumab in management of neovascular glaucoma.

The clinical significance of carbon-ion radiotherapy (CIRT) for adenocarcinoma (AC) of the uterine cervix has been assessed in several single-institutional studies. To validate the significance, we conducted a multi-institutional survey of CIRT for locally advanced AC (LAAC) of the uterine cervix. We retrospectively analyzed the clinical outcomes of patients with stage IIB–IVA LAAC of the uterine cervix who underwent chemo-CIRT or CIRT alone between April 2010 and April 2016. Patients received 74.4 Gy (relative biological effectiveness [RBE]) in 20 fractions of CIRT or 55.2 Gy (RBE) in 16 fractions of CIRT plus three sessions of brachytherapy. Patients aged ≤ 70 years with adequate bone marrow and organ function were administered cisplatin weekly (40 mg/m2 per week for up to 5 weeks). Fifty-five patients were enrolled in this study. The median follow-up period was 67.5 months. The 5-year overall survival (OS) and local control (LC) rates were 68.6% and 65.2%, respectively. Multivariate analysis showed that the initial tumor response within 6 months was significantly associated with LC and OS. The present study represents promising outcomes of CIRT or chemo-CIRT for LAAC of the uterine cervix, especially in the cases showing initial rapid regression of the tumor.

e17515 Background: The purpose of the study was to evaluate advantages of combination ozone therapy as an effective factor of radiomodification and radioprotection in the treatment of patients with cervical cancer. Methods: The study included 20 patients with stage IIIb cervical cancer T3бNхM0, the mean age 52 years. Controls (n = 10) received standard chemoradiation therapy; the main group (n = 10) received combination ozone therapy in addition to chemoradiation therapy. Systemic ozone therapy involved intravenous administration of 250 ml ozonized solution of 0.9% sodium chloride, 15 sessions during external beam radiotherapy. Local ozone therapy involved 15-minute instillations into the vagina during brachytherapy. All patients received standard chemoradiation therapy, total irradiation dose to the primary focus 80 Gy, plus weekly cisplatin 40 mg/m2. Results: In the main group, pain and discomfort in the lower abdomen were managed in 20% patients by the 5th session of ozone therapy; 30% - on the 10th day; in 50% - on the 14th day. In the control group, such symptoms in 40% of patients were reduced after 20 days. The main group showed a more rapid regression of tumor infiltration, disappearance of purulent discharge, relief of intoxication syndrome. Manifestations of gastrointestinal toxicity were observed in 10% of the main group and in 100% controls; leukopenia developed in 7 patients in the control group and was not registered in the main group. MRI showed complete clinical regression in 90% in the main group and in 65% in the control group. The treatment was completed within 7 weeks in the main group and 8.5 weeks in the control group. Conclusions: Combination ozone therapy causes a more pronounced antitumor effect, and its radioprotective effects significantly reduce the severity of chemotherapy-induced disorders. It does not aggravate concomitant pathology and shortens the treatment period.

Congenital hemangiomas are rare benign vascular tumors that develop in utero and are fully formed by the time of birth. Depending on the ability to involution, there are three subtypes: RICH (repidly involuting congenital hemangioma), NICH (non involuting congenital hemangioma), PICH (partially involuting congenital hemangioma). PICH may be accompanied by thrombocytopenia and consumption coagulopathy. Despite clearly defined clinical and histological characteristics, it can be difficult to make a differential diagnosis between congenital hemangiomas and other vascular tumors (infantile hemangioma, kaposiform hemangioendothelioma/“fascicular” angioma and others). The clinical case in the article of a vascular tumor in a newborn complicated by thrombocytopenia and consumption coagulopathy was regarded as Kazabach-Merritt syndrome, which is based on kaposiform hemangioendothelioma/“fascicular” angioma. Rapid regression of the tumor and recovery of hemogram and coagulogram parameters, as well as anamnesis of the disease and initial characteristics of the tumor forced to reconsider the diagnosis. Based on the histological picture, the diagnosis of congenital hemangioma, RICH, was confirmed. Verification of the diagnosis made it possible to change therapeutic tactics and avoid chemotherapy. A giant hemangioma, accompanied by thrombocytopenia and consumption coagulopathy, may have a very favorable outcome – a complete resolution of the pathological process inherent in its natural course. The patient's parents agreed to use the information, including the child's photo, in scientific research and publications.

The article presents a case of scarlet fever on the background of toxicodermia in a 12-year-old girl. The disease most probably developed in response to a combination of etiological factors such as bacterial infection and allergic reaction to exotoxins. The clinical picture was dubious, involving mucous membranes of the nose, mouth, and skin. Parenteral administration of glucocorticoids, antihistamines, detoxification, antibiotic therapy, and topical treatment led to rapid regression of clinical symptoms and prevented the development of complications. Sometimes, it is difficult to determine the etiology of toxicodermia combined with scarlet fever. Physicians should examine all patients with allergodermatoses for the presence of beta-hemolytic streptococcus and antibodies.

<p>The Ludfordian Carbon Isotope Excursion (LCIE) reached the highest known δ<sup>13</sup>C values in the Phanerozoic. It was a global environmental perturbation manifested in a rapid regression attributed to glacial eustasy. Previous studies suggested that it has also heavily affected the diversity of conodonts, early vertebrates and reef ecosystems, but the timing of the crisis and recovery remained complicated owing to the lateral variability of δ<sup>13</sup>C values in epeiric platforms and rapid facies shifts, which drove faunal distribution. One of the best records of this interval is available in the Swedish island of Gotland, which preserves tectonically undisturbed strata deposited in a Silurian tropical carbonate platform. We revisited the world-renowned collection of the late Lennart Jeppsson, hosted at the Swedish Museum of Natural History, Stockholm, which holds the key to reconstruct the dynamics of faunal immigration and diversification following the LCIE. Here we focus on the Burgen erosional outlier, which remained a mystery, as it had been correlated with the excursion strata, but preserved a high diversity of conodonts and reefal ecosystems. We re-examined key outcrops and characterized macro- and microfacies, as well as chemostratigraphy and unpublished fauna in the collection. Strata in the Burgen outlier represent back-shoal facies of the Burgsvik Oolite Member and correspond to the Ozarkodina snajdri Conodont Biozone. The shallow-marine position compared to the more continental setting of coeval strata in southern Gotland, is reflected in the higher δ<sup>13</sup>C<sub>carb</sub> values, reaching +9.2‰. The back-shoal succession in this outcrop includes reefs, which contain a large proportion of microbial carbonates and have therefore been previously compared with low-diversity buildups developed in a stressed ecosystem. However, the framework of these reefs is built by a diverse coral-stromatoporoid-bryozoan fauna, indicating that a high microbial contribution might be a characteristic of the local carbonate factory rather than a reflection of restricted conditions. In the case of conodonts, impoverishment following the LCIE might be a product of facies preferences, as the diverse environments in the outlier yielded at least 20 of the 21 species known from the Burgsvik Formation in Gotland. Fish diversity also returned to normal levels following the LCIE with an estimated minimum of 9 species. Thelodont scales appear to dominate samples from the Burgen outlier, which is in line with previous reports. Our observations highlight how palaeoenvironmental reconstructions inform fossil niche and diversity analyses, but also how fossil museum collections continuously contribute new data on past biodiversity.</p>
