Pulmonary artery thrombosis is considered to be the thrombotic obstruction of the pulmonary artery branches in the absence of venous and cardiac chambers thrombosis. \u0000Patient S. with COVID-19 and 75% of lung involvement was treated in the accordance with the actual COVID-19 treatment recommendations. Enoxaparin sodium 6000 IE once a day followed by the increasing dosage of 8000 IE twice a day was used. To prevent exacerbation tocilizumab was infused, and systemic thrombolytic therapy was performed. On the 6th day after systemic thrombolytic therapy patient died. Examination revealed thrombi in the pulmonary artery branches. \u0000Patient P. with continued growth of cerebral left frontoparietal region glioblastoma was hospitalized. Surgical tumor removal was performed a year ago. Conservative therapy, dexamethasone injections and anticoagulant prophylaxis (enoxaparin sodium 4000 IE once a day) were prescribed. After the patient death thrombi were found in the pulmonary artery segmental branches. \u0000Outpatient D. had a history of four episodes of dyspnea during the acute respiratory diseases. Computed tomography performed at the time of the third and fourth episodes revealed thrombi in the pulmonary artery segmental branches. The fourth episode occured despite anticoagulant prophylaxis with rivaroxaban (10 mg once a day). Patient was recommended to switch to low molecular weight heparins in case of any disease. There have been no recurrent episodes over the past 8 months. \u0000Distinctive features of pulmonary artery thrombosis pathogenesis determine the development of the complication despite anticoagulant prophylaxis. Preventive effect of anti-inflammatory drugs on the pulmonary artery thrombosis development has not been demonstrated.","PeriodicalId":12949,"journal":{"name":"HERALD of North-Western State Medical University named after I.I.

Diagnostic errors are associated with the fact that myasthenia gravis and other diseases of the nervous system have similar symptoms. The most common misdiagnosis in the onset of myasthenia gravis is a stroke. However, the reasons for a false diagnosis remain unspecified and poorly understood. \u0000AIM: To determine the factors leading to misdiagnosis of a stroke in the onset of myasthenia gravis. \u0000MATERIALS AND METHODS: 133 patients diagnosed with myasthenia gravis were divided into two groups. Patients with misdiagnosed stroke at the onset of myasthenia gravis formed the first group, the rest of the patients – the second group. A comparative assessment was performed according to the age of myasthenia onset, the clinical variant of the onset, primary symptoms, the duration of diagnosis, and the severity of the disease at the time of the correct diagnosis, with the percentage of misdiagnosis calculation. \u0000RESULTS: Stroke as misdiagnosis was established more often than others (in 23% of all cases and in 44% of incorrect diagnoses). In the 1st group, complaints of dysarthria and dysphagia were significantly higher, myasthenia gravis began acutely more often, the age of myasthenia onset in patients of the 1st group was statistically higher than in the 2nd. There was no difference between the groups in terms of diagnosis duration, the disease severity, and the history of previous stroke. \u0000CONCLUSIONS: Factors leading to stroke misdiagnosis at the onset of myasthenia are advanced age and acute onset with bulbar disorders.","PeriodicalId":12949,"journal":{"name":"HERALD of North-Western State Medical University named after I.I.

Understanding mechanisms of metabolism of teeth hard tissues is the key to the stability of restorative treatments and occurrence of non-carious tooth lesions. The evolution of views on this problem is noteworthy. The literature review reveals the initial predominance of mechanical actions, abrasion, and mineralization. It is later complemented by a detailed analysis of the influence of destructive stresses and deformation due to mechanical factors. All the leading works of the 2000s are dedicated to analyzing the ultrastructural features of enamel that affect its mechanical characteristics and can explain both the characteristics of the shape and intensity of mechanical tooth wear during the functioning of the stomatognathic system, as well as the durability of the performed restorations.

Since the majority of patients undergo Hartmann surgery, the main problem is a large number of stoma patients. Three quarters of them live with a stoma for a long time, which negatively affects their quality of life and increases the cost of treatment. \u0000AIM: The purpose of this research work is to improve the immediate results of treating patients with perforative diverticulitis and peritonitis by using staged surgical tactics. \u0000MATERIALS AND METHODS: The reaserach included 14 patients with perforative diverticulitis Hinchey grade II-III. The average value of the Mannheim peritoneal index is 18.9 ± 6.3 points. At the first stage of surgical treatment, all the patients underwent colon resection with a zone of perforation of the diverticulum and leaving its muffled ends in the abdominal cavity. After lavage and drainage, temporary closure of the anterior abdominal wall was performed. After 24–48 hours, all the patients underwent colon reconstraction. \u0000RESULTS: The average age of the patients was 52.3 ± 12.4 years with 4 women (28.6%) and 10 men (71.4%). The average duration of the first stage was 105.7 ± 27.2 minutes, the second one — 113.2 ± 40.5 minutes. The average hospital-stays were 16.4 ± 7.2 days. There were no anastomosis failures and no lethal outcomes. Complications were noted in 9 patients (64.3%), grade I according to Clavien – Dindo — 83.4%. \u0000CONCLUSIONS: The tactics of early surgical treatment is a promising concept for patients with perforative diverticulitis. It provides rapid elimination of the septic focus during the first surgical operation, assumes early reconstruction of the intestine without increasing the number of complications and mortality, and can be used in patients with peritonitis.","PeriodicalId":12949,"journal":{"name":"HERALD of North-Western State Medical University named after I.I.

A systematic review of randomized controlled trials has been conducted; its results based on meta-analysis has been evaluated. \u0000A systematic search and selection of publications in Embase, PubMed, Cochrane Library, and eLibrary databases has been performed. The studied drugs were xanthine oxidase inhibitors: allopurinol and febuxostat. The study considered the following parameters such as efficacy endpoints, namely, glomerular filtration rate and serum uric acid after 3–15 months of follow-up. Clinical and methodological heterogeneity of the included randomized controlled trials has been assessed as well as publication bias and risk of systematic error. Synthesis has been performed using bivariate meta-analysis assessing residual statistical heterogeneity. \u00007 selected randomized controlled trials (1203 patients) have been included in the meta-analysis. This analysis revealed that medication urate-lowering therapy (allopurinol or febuxostat) was associated with higher glomerular filtration rate (+3.0 ml/min/1.73 m2; 95% confidence interval +0.4 to +5.6; p = 0.022) compared with the controls (placebo/no urate-lowering therapy) at 3–15 months of follow-up. Along with this, medication urate-lowering therapy (allopurinol or febuxostat) has been found to result in lower serum uric acid (−3.3 mg/dl; 95% confidence interval −3.8 to −2.8; р 0.001) compared to the controls (placebo / no urate-lowering therapy) at 3–15 months of follow-up. \u0000The results of the meta-analysis have demonstrated a positive role of allopurinol and febuxostat in increasing glomerular filtration rate and decreasing serum uric acid in patients with chronic kidney disease and asymptomatic hyperuricemia.

In this regard, it is extremely relevant to assess the results of therapy in real clinical practice. Currently, much attention is paid to the study of the level of proinflammatory cytokines, both as markers of inflammatory activity of rheumatoid arthritis and monitoring the prognosis of anti-inflammatory therapy efficacy. In Russia, there are no works devoted to the study of cytokine concentration dynamics in patients with rheumatoid arthritis on the background upadacitinib therapy, which proves the relevance of the following study. \u0000AIM: To investigate the dynamics of clinical and laboratory values of inflammatory activity of the disease and cytokines in patients with rheumatoid arthritis associated with upadacitinib therapy. \u0000MATERIALS AND METHODS: We examined 10 patients with a reliable diagnosis of rheumatoid arthritis: patients’ age was 46.30 ± 10.20 years and disease duration was 12.00 (3.00–21.00) years. All the patients had moderate to high disease activity: Disease Activity Score-28 with erythrocyte sedimentation rate 5.48 (4.50–5.80), Clinical Disease Activity Index 28.00 (19.50–32.00) and Simple Disease Activity Index 29.18 (19.51–33.05). All the patients included in the study were treated with upadacitinib at a dose of 15 mg once a day against the background of the therapy with methotrexate, leflunomide, non-steroidal anti-inflammatory drugs and glucocorticoids. Observation was carried out before treatment and after 3, 6 months of therapy. Serum levels of 15 cytokines: interleukin-1β, -4, -6, -10, -17A, -17F, -21, -22, -23, -25, -31, -33, tumor necrosis factor-alpha, interferon gamma, soluble СD40 ligand were studied using multiplex xMAP technology. \u0000RESULTS: After 3 and 6 months of upadacitinib therapy, there was a significant decrease in Disease Activity Score-28 with erythrocyte sedimentation rate 3.78 (2.53–4.20) and 3.5 (2.00–3.68), Clinical Disease Activity Index 12.00 (5.00–17.34) and 9.0 (3.00–11.00), Simple Disease Activity Index 12.38 (5.02–17.00) and 9.61 (3.06–11.60), erythrocyte sedimentation rate 19.0 (11.0–26.0), 7.0 (4.0–18.0), CRP 0.56 (0.50–1.99), 0.71 (0.51–1.1).
