Vibration disease is one of the leading in the structure of occupational diseases. A more detailed study of the pathogenesis, expanding the possibilities of diagnosis of vibration disease, is necessary. The aim of the study is to determine the diagnostic value of stabilometry, quantitative sensory testing and neuroenergocarting in vibration disease associated with the combined effects of local and general vibration. Materials and methods. Two groups of patients were examined: with the diagnosis of vibration disease associated with the combined effect of local and general vibration – 50 people (age 48.7 ± 3.1 years), not in contact with vibration – 30 people (age 49.1 ± 2.8 years). The study of the equilibrium function, the determination of the level of the constant potential of the brain by 12 standard leads and the determination of temperature and pain sensitivity. Statistical processing of the results was carried out using the software package “Statistica 6.0” (StatSoft Inc., USA). Differences were considered statistically significant at p < 0.05. Results. In vibration disease, the vertical stance of patients is more unstable than in patients with no contact with vibration. In patients with vibration disease, there is a decrease in the threshold of cold sensitivity and an increase in the threshold of thermal sensitivity and thermal pain compared to the control group. According to our data, the increased level of permanent potential in patients with vibration disease is observed in the central (22.7 (12.6; 30.7) mV) and right central (20.4 (11.5; 27.1) mV), also the average level of permanent capacity in this group is increased – 17.1 (8.4; 25.8) mV.Conclusion. The results obtained indicate the involvement of the neurosensory complex united by single thalamic and cortical centers in the pathological process and confirm the diagnostic value of the methods used.

Abstract: A statistical analysis of stabilometric study results of 50 male patients with vibration disease (VD) from the effects of general vibration (GV) (average work experience 26,7±6,2) has been carried out. The control group (CG) included 50 men who have not been exposed to the general vibration. The compared groups were comparable by age: the average age of patients with vibration disease was 56.34+5.15, patients of the control group-58.22+-7.05. The study of the support symmetry and equilibrium function was carried out using the Romberg test on the St-150 stabiloplatform (Biomera, Moscow) in a vertical stand with European installation of feet in the positions of open (OE) and closed eyes (CE). A comparative analysis of the parameters of support symmetry in patients with VD from GV revealed a statistically significant sagittal asymmetry in the phases of OE and CE than in individuals of CG. Among the balancing parameters, the most informative parameters of computer stabilometry in patients with VD from GV were: an increase in the area of the statokinesiogram, a decrease in energy efficiency in both phases of the study, and an increase in the speed of the statokinesiogram in phase with CE. Computer stabilometry can be recommended as an additional objective research method in the diagnosis of early stages of VD from GV to improve the quality of periodic medical examinations.

Abstract Objectives This study was designed to evaluate the role of anti-CD74 antibodies in diagnosis of axial spondyloarthritis (axSpA) and their relationship to disease duration and disease activity. Methods Fifty patients with axSpA, 15 patients with RA and 15 healthy subjects were included in the study. Clinical examination and laboratory tests were done. The ESR, CRP level and ASDAS were measured as markers of the disease activity. Quantitative determination of human CD74 IgG antibodies was done. Results The mean age of the patients was 38.22 (S.D.12.20) years. The level of CD74 autoantibodies was significantly higher in axSpA in comparison to control groups. Most patients with positive articular and extra-articular manifestations were positive for CD74 autoantibodies. In patients with inactive disease, 33.3% were positive for CD74 autoantibodies, as were 83% with active disease. High percentages of patients with early and late axSPA were CD74 autoantibody positive. The majority of patients with positive disease activity in early and late axSpA were CD74 autoantibody positive. CD74 autoantibodies had 80% sensitivity vs both control groups with 87% specificity vs the healthy control group and 80% vs the RA control group in the diagnosis of axSpA. Conclusions The frequency of positive anti-CD74 IgG antibodies was as high in patients with early axSpA as in those with late axSpA, with no significant differences. There was a significant difference in the frequency of positive anti-CD74 IgG antibodies between patients with positive and negative disease activity. Based on the sensitivity and specificity of anti-CD74 IgG, this is a promising diagnostic tool to support the clinical diagnosis of axSpA.

The article presents the results of clinical examination of periodontal tissues in adolescents against the background of alimentary-constitutional obesity.The aim of the study – to investigate the features of the course of diseases of the periodontal tissue according to clinical indices in persons with alimentary-constitutional obesity.Materials and Methods. As a result of the survey, 95 adolescents aged 16–18 years old were included to study the features of the course of infl ammatory diseases of periodontal tissues in adolescents with alimentary-constitutional obesity 76 adolescents and 19 adolescents with harmonious physical development. To clarify the diagnosis, «excessive body weight» was determined by weight and height of the patient, and measured the circumference of the waist and hips. In the future, the body mass index (BMI) was calculated as the ratio of body weight in kg to square of growth in m2. Diagnosis of excess body weight was confi rmed with BMI less than 30kg/m2. The evaluation of the condition of periodontal tissues was carried out according to subjective and objective criteria (clinical parameters, index score). For the verifi cation of the pathological process in the periodontium, the classifi cation of M. F. Danilevskyi (1994) was used. The state of periodontal tissues was described using a traditional index score. Statistical processing of the results was carried out using commonly used methods of variation statistics with a help of personal computer using a statistical software package «Statistica 8.0» («Statsoft», USA). The probability level was estimated at 95 % (p<0.05) using Student’s t criterion.Conclusions. Consequently, the clinical indicators of the state of periodontal tissues in the context of alimentaryconstitutional obesity (Fedorov-Volodkin’s index, Green-Vermillion index, Sillness-Loe index, CPITN index) signifi cantly deteriorate compared with the corresponding indicators in the control group of adolescents without AKO, indicating the effect of alimentary-constitutional obesity on the clinical course, the severity and severity of theinfl ammatory process and the feasibility of timely and effective pharmacotherapy.

Aim - to study the state of cellular immunity and cytokine profile at vibration disease due to exposure to local and general vibration, taking into account the severity of the disease. Assessing the role of immunological changes in the pathogenesis of vibration disease. Material and methods. The study involved 84 patients with various forms and severity of vibration disease due to exposure to local and general vibration. The control group included 30 people who did not have contact with occupational hazards at work and who were recognized as healthy according to a complete physical examination. Diagnosis was based on occupational history, sanitary characteristics of working conditions (work in contact with local or general vibration, the vibration levels excessing maximum acceptable level for more than 15 years), full clinical functional screening and instrumental examination of patients. Methods of immunological study included determination of subpopulations of lymphocytes, levels of cytokines IL-ф, IL-4, IL-8, tumor necrosis factor alpha (TNF-а) in serum by ELISA. Statistical processing of the data was performed using SPSS software package 21. Results. The study revealed a significant decrease in helper (CD4+) and suppressor (CD8+) subpopulations of lymphocytes, increase of concentration of pro-inflammatory cytokines IL-ф, IL-8, TNF-а; reduction in anti-inflammatory cytokine IL-4 in patients with vibration disease compared with the control group, regardless of the type of vibration, but more pronounced at the second degree of vibration disease due to general vibration. Revealed changes are indicative of the activation of inflammatory processes, violation of immunological reactivity, the presence of cytokine imbalance as the effect of exposure to occupational vibration. Conclusion. The study of the immunological profile (cellular link, cytokine profile) at vibration disease opens up prospects for rehabilitation and treatment of patients with this pathology, and also elaborates our knowledge of the pathogenesis of this disease.

Postural Disorders

Introduction. Vibration disease (VD) is one of the leading occupational diseases. One of the manifestations of this disease when exposed to general vibration may be a violation of balance.The aim of the study is to identify the imbalance and the causes of their occurrence in patients with vibration disease.Materials and methods. 3 groups of patients were examined. The first group consisted of 50 patients diagnosed with VD associated with combined exposure to local and general vibration (age 48.7±3.1 years); the second group consisted of 50 patients diagnosed with VD associated with exposure to local vibration (age 48.9+2.8 years); the control group consisted of 50 relatively healthy men not in contact with vibration (age 49.1+2.5 years). Survey on electronic stabilometer ST–150 (Biomera, Russia). Patients performed the Romberg test standing barefoot vertically on a stabilometric platform with a “European” stop position. Statistical processing of the results was carried out using the software package “Statistica 10.0” (StatSof, USA, 2011). Methods of descriptive statistics included estimation of median, lower and upper quartiles. The statistical significance of the differences was determined using the nonparametric Wilkinson method. Differences were considered statistically significant at p<0.05.Results. In the analysis of the obtained stabilometric parameters found that in the first group of patients marked imbalance.Moreover, in comparison with the second group and the control group in the phase with eyes closed, patients are more difficult to maintain a given posture, which increases the length of statokinesigram (p=0.02 and p=0.005), increasing the speed of movement of the center of pressure (p=0.03 and p=0.004) and the square of the deviation of the center of pressure (p=0.03 and p=0.004). When closing the eyes, patients put more effort to maintain balance, which affects the rate of mechanical work (p=0.001 and p=0.001). When comparing the second group with the control group, no statistically significant difference was found in the main stabilometric indicators.Conclusions: In the group of patients with VD associated with the combined effects of local and general vibration, marked (64%) and moderate (36%) postural disorders, especially in the phase of closed eyes. In the group of patients with VS associated with local vibration exposure and in the control group, imbalance was detected in 10% and 6%, respectively. The leading role in the occurrence of postural disorders in patients with VD, associated with the combined effects of local and general vibration, plays the formation of a focus of stagnant excitation in the centers of vibration sensitivity. In the future, the pulse can spread to nearby centers of pain, temperature sensitivity and proprioception, which contributes to the emergence of lower limb polyneuropathy and impaired stability in patients with vibration disease.

Aim. To improve the diagnosis of allergic skin diseases in childrenMaterials and methods. 135 children aged from 2 to 6 with atopic dermatitis were examined during exacerbation. They were on inpatient treatment in the skin and venereologic department of the Regional skin and venereologic dispensary and the Department of Allergology of the Regional children's clinical hospital. At the same time, 103 people (the main group) had uncomplicated course of the disease, 32 patients had complications of atopic dermatitis in the form of secondary infection. The control group consisted of 29 children aged 2 to 6. Neopterin in serum was determined by enzyme-linked immunosorbent analysis using test kits "Neopterin ELISA" (Germany). Statistical reliability of the obtained data was evaluated using The Student's test.Results. Atopic dermatitis in children, regardless of clinical manifestations, is accompanied by an increase in the content of neopterin in serum. The nature of the increase in the level of neopterin is determined by the duration of the disease, while its highest values are characteristic of the prolonged course of the process (over 4 years).Conclusion. The determination of neopterin in children with atopic dermatitis is a promising laboratory method for assessing the severity of dermatosis, monitoring and forecasting the further course of the process, as well as evaluating the effectiveness of therapeutic measures.

The Diagnostic Value of N-Acetyl-β-D-Glucosaminidase and Microalbumin Concentrations in Rheumatoid ArthritisThe purpose of this research was to compare the diagnostic values of laboratory variables, to present quantitative evaluations of the diagnostic sifted test with reference to sensitivity and specificity, the predictive value of the positive and negative test and precision of the test for N-acetyl-β-D-glucosa-minidase (NAG), microalbumin, rheumatoid factor (RF), Creactive protein (CRP), DAS 28 index, in early diagnosis of untreated rheumatoid arthritis (RA), and to define the effect of untreated rheumatoid arthritis on glomerular and tubular function. Using a colorimetric assay for the determination of Nacetyl-β-D-glucosaminidase and an immunoturbidimetric assay for the determination of urinary albumin, the samples of serum and urine have been examined in 70 participants (35 RA who were not treated, 35 healthy controls). RF was defined with the test for agglutination (Latex RF test) in the same participants. Out of 35 examined patients with RA, in 13 we found the presence of NAG enzymuria (sensitivity of the test 37.14%), while microalbuminuria appeared in 4 patients (sensitivity of the test 11.42%). RF appeared in 17 patients (sensitivity of the test 48.57%). Four patients were NAG and RF positive, while 3 patients were microalbuminuria and RF positive. Among 18 RF negative patients, 9 patients were NAG positive, and 1 patient presented with microalbuminuria. Among 17 RF positive RA, the presence of NAG was found in 4 patients, and the presence of microalbuminuria in 3 patients. Among 18 RF negative RA, NAG enzymuria appeared in 9 patients. Microalbuminuria was present in 1 patient. In the healthy control group, 8 patients were NAG positive, 2 patients were positive for microalbuminuria. RF appeared in 2 patients. NAG has higher sensitivity than microalbuminuria in the detection of asymptomatic renal lesions in untreated RA.

Abstract Background Acute leukemias are malignant neoplastic diseases that arise from either lymphoid [ALL] or myeloid [AML] cell lines that are distinguished by the proliferation of BM non-functional immature cells and subsequently released into the bloodstream. ALL is prevalent malignancy in young, while AML in older. Diagnosis is usually routinely performed through peripheral blood count and smear then confirmed by BM aspirate. It is remarkable to notice that leukemia can be manifested at high, low, and even at normal leucocyte count. While treatment results have improved steadily over the last decades in younger and adults, limited changes have been in survival among subjects of age > 60 years. Aim of the work is to measure the serum estrogen [E2] and its soluble receptor [ER] levels in acute leukemia patients and extrapolate its possible clinical significance. This study included 40 [20 females and 20 males] healthy volunteers clinically free from any disease, 40 [20 females and 20 males] AML patients, and 40 [20 females and 20 males] ALL. To all subjects, serum E2 and its soluble ER level were investigated by ELISA. Results Serum E2 [pg/ml] level was lower in AML and ALL female and male patients groups than control group. Serum ER [ng/ml] level was lower in AML and ALL female and male patients groups than control group. Conclusion Estimation of serum E2 and its soluble ER level is of edifying diagnostic value. Determination of serum E2 and its soluble ER level in AML and ALL patients is of value in deciding treatment therapeutic target protocol.
