OSTEOPETROSIS AND ENDOPROSTHETICS - CLINICAL OBSERVATIONS
Aim - to evaluate the efficacy of treatment of secondary arthrosis of the coxofemoral joints associated with osteopetrosis using arthroplasty. Materials and methods - clinical observation of two cases of treatment of patients with autosomal dominant form of osteopetrosis who underwent total hip arthroplasty at the Federal State Budgetary Institution Federal Center of Traumatology, Orthopaedics and Endoprosthesis replacement (Cheboksary). Results. We obtained positive results and patientβs satisfaction with the function of prosthetic joints with a follow-up period of 3.5 years. This method of treatment showed its efficacy during the specified follow-up period. Arthroplasty provides relief from pain, improved quality of life and increased mobility of the joint for patients with coxarthrosis associated with osteopetrosis
Optimal treatment methods of infectious complications in cases of large joint replacement arthroplasty in modern conditions
Research objective: to choose optimal treatment methods in conditions of Federal Centers of high-technology medical carebased on the analysis of infectious complications in cases of large joint replacement arthroplasty. Materials and methods. In the Federal State Publicly Funded Institution βFederal Center of Traumatology, Orthopedics and Replacement Arthroplastyβ in Cheboksary city in the period from 2009 to 2014 there weremade 20761 large joint replacement operations. The incidence rate of deep infectious complicationsamounted to 0.3%. The average age of patients who had infectious complications was 61.2Β± 12.3 years old, and the male to female ratio was 1:2. Infectious complication risk factors have been evaluated using the continuous method, and the species composition of selected microflora have been studied. Based on the analysis of surgical intervention approaches the optimal method of surgical treatment has been determined. Results. The main predisposing infectious complication risk factors were chronic infection sites, diabetes, obesity, systemic inflammatory diseases, previous intra-articular administration of medicines, blood transfusions, repeated surgical manipulations in the area of the planned surgical intervention, as well as hematomas in the periprosthetic area identified in the postoperative period. The main germ of infectious complications is represented by gram-positive organisms, and the leading role belongs to staphylococci (52%). When identifying infection in the operated jointat the Center, such priority treatment strategiesas a two-stage replacement arthroplasty with long interval" (70.5%), single-stage revision surgery (23.5%), and three-stage revision surgery (6 % ) were used. Two-stage replacement arthroplasty with βlong intervalβ is an efficient treatment, as well as it is economically feasible. It is necessary to take into account the duration of an antibioticrelease from the cement spacer. Reduction of the period between reimplantations significantly reduces the proportion of re-revisions (from 9% to 4.5% , p<0.05), improves long-term results and increases the treatmentmotivation of patients.Π¦Π΅Π»Ρ ΠΈΡΡΠ»Π΅Π΄ΠΎΠ²Π°Π½ΠΈΡ: Π½Π° ΠΎΡΠ½ΠΎΠ²Π΅ Π°Π½Π°Π»ΠΈΠ·Π° ΠΈΠ½ΡΠ΅ΠΊΡΠΈΠΎΠ½Π½ΡΡ

Thrombosis: a note of caution! What a district therapist important to know about for patients after orthopedic surgery
The purpose of this article is to attract the attention of primary care physicians to the problem of prevention of venous thromboembolic complications (VTEC) in patients after orthopaedic surgeries. The article presents a complex approach to the prevention of VTEC in patients after arthroplasty of large joints, and provides a brief overview of oral anticoagulants used in modern clinical practice, depending on the level of venoocclusive disease on the one hand and development of undesirable side effects on the other hand. Taking into account the fact, that the average time of incidence of thromboembolic complications (VTEC) after arthroplasty of large joints is from 12 to 34 days, it is necessary for outpatient doctors to participate actively in prophylaxis of VTEC, early detection of clinical symptoms of thromboembolic complications, as well as in evaluation of undesirable side effects arising on the background of anticoagulants intake. This, in turn, will allow minimizing the mortality rate in patients of all age groups after orthopaedic surgeries.Π¦Π΅Π»ΡΡ Π΄Π°Π½Π½ΠΎΠΉ ΡΡΠ°ΡΡΠΈ ΡΠ²Π»ΡΠ΅ΡΡΡ ΠΏΡΠΈΠ²Π»Π΅ΡΠ΅Π½ΠΈΠ΅ Π²Π½ΠΈΠΌΠ°Π½ΠΈΡ Π²ΡΠ°ΡΠ΅ΠΉ ΠΏΠ΅ΡΠ²ΠΈΡΠ½ΠΎΠ³ΠΎ Π·Π²Π΅Π½Π° ΠΊ ΠΏΡΠΎΠ±Π»Π΅ΠΌΠ΅ ΠΏΡΠΎΡΠΈΠ»Π°ΠΊΡΠΈΠΊΠΈ Π²Π΅Π½ΠΎΠ·Π½ΡΡ

Diagnostically significant differences septic and aseptic instability of endoprosthesis components during arthroplasty of large joints
The purpose of the work is to analyze the results of laboratory, microbiological and instrumental studies to search for screening criteria for the difference between aseptic and septic instability of endoprosthesis components after knee and hip joint arthroplasty. The materials contained 146 cases of revision arthroplasty of the knee and hip joints, performed under the conditions of Federal State Budgetary Institution Federal Center of Traumatology, Orthopedics and endoprosthesis replacement of Ministry of Health of the Russian Federation (Cheboksary) for a 3-year period, including cases of aseptic instability - 69, septic instability-77. By methods for laboratory diagnosis were used to evaluate the blood levels of leukocytes, stab neutrophils, ESR, C-reactive protein (CRP), presepsin, procalcitonin, D-dimer, interleukin-6. Using ultrasound (ultrasonic) examination of the periprosthetic zone, the presence of fluid, granulation tissue in the joint cavity, altered lymph nodes was determined. Before the operation, the level of cytosis and cellular composition were determined in the synovial fluid; tissue bioptates, removed components of implants (after ULTRASONIC treatment) with sowing on the microflora were studied intraoperatively. Intraoperative tissue biopsies were used to make smears-prints on the glass, with gram staining, estimating the number of leukocytes and neutrophils in the field of vision. Results. Determination of indicators of ESR, presepsin and interleukin-6, the level of which goes beyond the generally recognized normal values in the presence of infection, can be recommended as a screening test in the diagnosis of the infectious nature of instability of the components of the endoprosthesis of large joints. The second stage of differential diagnosis of septic and aseptic instability can be the detection of lymphadenopathy. The third (final) stage of determining the infectious nature of instability is an invasive technique to determine the level of cytosis with the calculation of neutrophils in the synovial fluid.Π¦Π΅Π»Ρ ΡΠ°Π±ΠΎΡΡ - Π°Π½Π°Π»ΠΈΠ· ΡΠ΅Π·ΡΠ»ΡΡΠ°ΡΠΎΠ² Π»Π°Π±ΠΎΡΠ°ΡΠΎΡΠ½ΡΡ

Evaluation of the effectiveness of the analgesic effect of selective and non-selective cyclooxygenase blockers in the composition of multimodal analgesia after knee joint endoprosthesis replacement
The purpose of the work is to compare the effectiveness of anesthesia with the use of a highly specific blocker COX-2 and a dedicated cyclo-oxygenase blocker COX-1 and COX-2 lornoxicam as part of multimodal analgesia in patients after primary knee replacement. The material was the cases of knee prosthesis (N=196) using multimodal analgesia; patients were divided into two groups, depending on the type of anesthesia, in accordance with the developed scheme of pharmacotherapy: I β receiving celecoxib (n=98) and II - lornoxicam (n=98). Methods for evaluating the effectiveness of anesthesia were the visual analogue scale (VAS), the KSS knee joint function evaluation scale before surgery and on the 5th day after it; analysis of the features of early verticalization, the patient's need for additional pain relief after surgery; costs of drug therapy are calculated. Results. Patients of both groups were comparable in age and average duration of hospitalization. The pain syndrome assessment on the VAS scale showed a higher efficacy of pain relief on days 1 and 5 in group II (4.1 Β± 0.1 versus 3.5 Β± 0.1 and 1.9 Β± 0.04 versus 1.6 Β± 0.1 points respectively) (pβ€0.05). Evaluation of the functional activity of the prosthetic knee joint on the KSS scale did not reveal any differences between the groups. Of the features of early verticalization on the first day after surgery, a higher percentage of weakness in the legs (79.6%) and nausea (70.4%) was noted in group I, and a higher percentage of dizziness (15.3%) and hemodynamic disorders (6.1% of cases). The cost of providing basic pain therapy in group I was 2.4 times higher than in group II, with the same costs for additional anesthesia with solutions of paracetamol and narcotic analgesics. Conclusions. As part of multimodal analgesia, Lornoxicam showed a higher efficacy in relieving pain syndrome at a low cost of a course of treatment compared with celecoxib.Π¦Π΅Π»Ρ ΡΠ°Π±ΠΎΡΡ - ΡΡΠ°Π²Π½Π΅Π½ΠΈΠ΅ ΡΡΡΠ΅ΠΊΡΠΈΠ²Π½ΠΎΡΡΠΈ ΠΎΠ±Π΅Π·Π±ΠΎΠ»ΠΈΠ²Π°Π½ΠΈΡ ΠΏΡΠΈ ΠΈΡΠΏΠΎΠ»ΡΠ·ΠΎΠ²Π°Π½ΠΈΠΈ Π²ΡΡΠΎΠΊΠΎΡΠΏΠ΅ΡΠΈΡΠΈΡΠ½ΠΎΠ³ΠΎ Π±Π»ΠΎΠΊΠ°ΡΠΎΡΠ° Π¦ΠΠ-2 ΡΠ΅Π»Π΅ΠΊΠΎΠΊΡΠΈΠ±Π° ΠΈ Π½Π΅ΡΠΏΠ΅ΡΠΈΡΠΈΡΠ½ΠΎΠ³ΠΎ Π±Π»ΠΎΠΊΠ°ΡΠΎΡΠ° ΡΠΈΠΊΠ»ΠΎΠΎΠΊΡΠΈΠ³Π΅Π½Π°Π·Ρ Π¦ΠΠ-1 ΠΈ Π¦ΠΠ-2 Π»ΠΎΡΠ½ΠΎΠΊΡΠΈΠΊΠ°ΠΌΠ° Π² ΡΠΎΡΡΠ°Π²Π΅ ΠΌΡΠ»ΡΡΠΈΠΌΠΎΠ΄Π°Π»ΡΠ½ΠΎΠΉ Π°Π½Π°Π»ΡΠ³Π΅Π·ΠΈΠΈ Ρ ΠΏΠ°ΡΠΈΠ΅Π½ΡΠΎΠ² ΠΏΠΎΡΠ»Π΅ ΠΏΠ΅ΡΠ²ΠΈΡΠ½ΠΎΠ³ΠΎ ΡΠ½Π΄ΠΎΠΏΡΠΎΡΠ΅Π·ΠΈΡΠΎΠ²Π°Π½ΠΈΡ ΠΊΠΎΠ»Π΅Π½Π½ΠΎΠ³ΠΎ ΡΡΡΡΠ°Π²Π°.

Regulation of the urokinase-type plasminogen activator gene by the oncogene Tpr-Met involves GRB2
The oncogene Tpr-Met is a constitutively active form of the hepatocyte growth factor/scatter factor (HGF/SF) receptor Met. It comprises the intracellular moiety of Met linked to the dimerization domain of the nuclear envelope protein Tpr, thus functioning as a constitutively activated Met. HGF/SF is responsible for various biological processes including angiogenesis and wound healing, in which secreted serine protease urokinase-type plasminogen activator (uPA) is implicated. The action of HGF/SF on cells is mediated by the autophosphorylation of Met on two carboxyterminal tyrosine residues, Y1349VHVNATVY1356VNV. The two tyrosine residues provide docking sites for various effector molecules, suggesting that multiple signaling pathways are activated to exert biological effects of HGF/SF [Ponzetto et al., Cell (1994) 77: 261]. We found that Tpr-Met efficiently activates the uPA gene via a SOS/Ras/extracellular signal regulated kinase (ERK)-dependent signaling pathway. Mutation of Y1356, which abrogates GRB2 binding, reduced the induction to half of the control level, while mutation of Y1349 showed little effect on uPA induction, suggesting an important but partly replaceable role for GRB2 in Met-dependent uPA gene induction. Mutation of both Y1349VHV and Y1356VNV into optimal PI 3-kinase sites resulted in a residual induction of about one quarter of the control level, suggesting a potential role for PI 3-kinase. Dose-response analysis of the Tpr-Met showed a biphasic curve. These results suggest that the interplay among different signaling molecules on the receptor is important for full induction of the pathway leading to the activation of the uPA gene
