The objective: The purpose of the study is to establish the role of infection with herpes simplex viruses type I and II in the pathogenesis of urogenital infection in pregnant women. Patients and methods: 89 patients of I, II trimester gestation, aged 18 to 35 years (average age of 27.5 ± 5.6 years) were examined. The design of the research and the methodology of verification of the UGI pathogens of pregnant women are presented in previously published materials. The establishment of character of pregnancy course (urgent delivery, premature birth, termination of pregnancy and mis-carriage), the presence or absence of infection and/or clinical manifestations of infectious and inflam-matory diseases, as well as evaluating the gene expression of TLR-2, TLR-3, TLR-4, TLR-8 (in relative units - RU) was conducted according to manuals. Results: It is established, that in UGI in pregnant combined viral-bacterial infection is registered. Viral component of UGI pathogens in pregnant women is presented by the association of viruses from the Herpesviridae family - herpes simplex viruses, Cytomega-lovirus, Epstein-Bar virus. Against the background of polyfactorial mechanisms of the pathogenesis of abortion, extra maximum activation of gene expression of TLR (22-23 RU or more) additional external factors, for example, infections can be an aggravating pathogenetic factor of miscarriage. Reduced expression of genes of TLR2, TLR4, TLR3 and TLR8 in the mucous membrane of the cervical canal in UGI of pregnant women in infection with herpes simplex virus due to the oppressive effect of pregnancy on the reaction of TLR, combined with the immunodepressive effect of the virus itself. With the violation of cellular part of immuno-logical reactivity of the body under the influence of adverse endogenous and exogenous factors on the process of pregnancy is activated the infectious process caused by the bacte-rial-viral pathogens association, which is accompanied by hyper reaction and increased reaction from the expression of genes of TLR, determines the pathological development of pregnancy. It is established that in the UGI of pregnant gene expression levels of TLR2-21.2 and above, TLR4-23.0 and above, TLR8 - 26.0 and above (the level of gene expression of TLR8 above 28 is the predictor of the onset of abortion and miscarriage) testify to the acute infectious process with the clinical manifestations of the UGI, and also indicates the possible interruption of pregnancy and miscarriage; levels of gene expression of TLR2 below 21.2, TLR4 below 23.0, TLR8 below 26.0, in-dicated a decrease in the severity of the infectious process and its chronicity, as well as the possibility of direct microbial damage to the tissues of UGT, placenta, and fetus. Conclusion: Verified in preg-nant women in 61% of cases clinical manifestations of the infectious process are necessarily associated with the verification of the association of herpes simplex viruses I and II type - triggers of infectious process deterioration, determining the prognosis and outcome of the development of the UGI in preg-nant.

Idiopathic lobular panniculitis (ILP) (synonym: Weber-Christian panniculitis) is the least studied disease in the group of systemic connective tissue lesions and characterized by systemic damage to subcutaneous adipose tissue (SAT). There is no unified concept of the etiology and pathogenesis of ILP now. The literature contains almost no data on the diagnostic value of laboratory studies and therapeutic approaches, which served as the basis for this investigation. Objective: to investigate the relationship between the clinical presentation of ILP and immune inflammatory parameters in patients with this disease. Subjects and methods. Examinations were made in 67 patients (9 men and 58 women) aged 20 to 76 years with a verified diagnosis of ILP (median duration, 78.91 [48; 540] months), who were followed up at the V.A. Nasonova Research Institute of Rheumatology for the period 2007 to 2017. The determination of α1-antitrypsin titer, liver fractions, amylase, lipase, trypsin, ferritin, creatine phosphokinase, leptin, and tumor necrosis factor-α (TNFα), chest computed tomography, and induration morphological examination were done in addition to physical examination. Results and discussion. The disease was found in all age groups, but it accounted for more than half (57%) of cases at the most able-bodied age (45–60 years). Analysis of the clinical manifestations of ILP could identify its four types: nodular (n=30), plaque (n=10), infiltrative (n= 5), and mesenteric (n=12), which were characterized by typical clinical features. The observed group showed a significant increase in erythrocyte sedimentation rate (ESR) (p=0.01) and C-reactive protein (CRP) level (p < 0.0001). ESR correlated with tenderness on the visual analogue scale (VAS) (p<0.05; r=0.29), induration area (p<0.05; r=0.50), and rises in body temperature (p<0.05; r=0.68) and CRP level (p<0.05; r=0.68). The concentration of CRP correlated with tenderness on visual analog scale (p<0.05; r=0.46), induration area (p<0.05; r=0.61), node stage (p<0.05; r=0.41), and TNF-α concentrations (p<0.05; r=0.32). The latter showed a direct correlation with node stage (p<0.05; r=0.41) and leptin levels (p<0.05; r=0.28) and an inverse correlation with the number of nodes (p<0.05; r=-0.24). Leptin levels were increased in 35 (52.23%) patients and displayed a direct correlation with body mass index (p<0.05; r=0.46), induration area (p<0.05; r=0.31), CRP level (p<0.05; r=0.36) and an inverse correlation with the number of nodes (p≤0.05; r=-0.33). Morphological examination of skin and SAT biopsy specimens was performed in 65 (97.01%) patients. Pre- and retroperitoneal adipose tissues were biopsied in three of five patients without skin and SAT lesions; this was not done in the remaining patients because of access difficulties. ILP was verified in all cases. Therapy was performed using the essential drugs adopted in rheumatology practice. Their therapeutic effects were noted in 62.68% of cases; inefficiency and health deterioration were detected in 12 (17.91%) patients, which necessitated an increase in the dose of disease-modifying antirheumatic drugs. Seven patients were given the following biological agents: abatacept (n=2), adalimum-ab (n = 3), etanercept (n=1), and rituximab (n=1). Conclusion. There is an obvious need to expand knowledge about this pathology amongst physicians and to conduct further investigation in order to timely diagnose and search for the most effective treatment options for ILP.

The clinical manifestations of dystonia are extremely variable; many of its forms are often undiagnosed. Dystonia is a sensorimotor disorder of the nervous system. Damage affects not only one structure, but also a network of the nodes interacting with each other in the somatosensory cortex and associative sensory and motor fields, which play a role in the integration of various sensory modalities coming from both outside the body and from the receptors within it. Botulinum toxin preparations show the highest efficacy in treating cranial dystonia. If their administration cannot achieve a positive result, oral drugs and surgical treatments should be used.

Peripheral nervous system involvement may be a main manifestation of systemic amyloidosis or occur in the later stages of the disease in the presence of multiple organ pathology. Focal, multiple mononeuropathy, radiculopathy, polyneuropathy, autonomic nervous system dysfunction, and myopathy develop depending on the localization of amyloid deposits in the peripheral nervous system. The most characteristic symptom in systemic amyloidosis is sensorimotor polyneuropathy accompanied in most cases by the involvement of autonomic nerve fibers in the pathological process. In cases of systemic amyloidosis, peripheral nervous system involvement is progressive, leading to disability, which makes the early diagnosis of the disease and its neurological manifestations and subsequent pathogenetic therapy relevant.
