Perspectives for vertebrology teaching development in higher medical schools

Year: 2015, volume 11 Issue: №2 Pages: 210-212
Heading: Pedagogics and Education Article type: Author's opinion
Authors: Norkin I.A., Zaretskov V.V., Levchenko K.K., Fedonnikov A.S., Zaretskov A.V., Kireev S.N.
Organization: Saratov State Medical University
Summary:

The article deals with the issues on improving the efficiency of vertebrology teaching in specialist training at pre-and postgraduate stages. Modern epidemiologic trends for spine traumas and diseases form the increasing interest to the problems of care and prevention of the considered pathology and define the necessity of single-skilled specialists training. Developing vertebrology into a separate discipline that is studied at medical universities at both pre- and postgraduate stages is one of the topic issues for higher medical schools where the search of effective ways of its realization is stressed.

Summary:

Purpose: to define regularities of variability of bone structures of a hip joint depending on type of dysplastic coxarthrosis and to develop tactics of total endoprosthesis replacement. Objects of research. 106 patients with dysplastic coxarthrosis of varying severity, passing treatment on the basis of Federal State Budget Institution of Saratov Scientific Research Institute of Traumatology and Orthopedics from 2005 to 2014 applying methods X, KT-, MRT-metry variation and statistical methods. Results: According to anatomic features of a hip joint at dysplastic coxarthrosis of various types algorithms of choice of acetabularand femoral components of endoprosthesis, and also tactics of total endoprosthesis replacement in groups of research are developed. Conclusion. The choice of a standard size of an endoprosthesis of a hip joint needs to be carried out taking into account X-ray anatomic features of a hip joint and degree of expressiveness of the dysplastic changes. At dysplastic coxarthrosis of the l-ll types it is necessary to carry out standard total endoprosthesis replacement; at coxarthrosis of the III type —total endoprosthesis replacement in combination with plasticity of a roof of acetabular hollow; at coxarthrosis of the IV type — total endoprosthesis replacement in a combination from the shortening femur osteotomy.

Summary:

Objective: immunological differentiation effects regeneration of nerve tissue in the acute and early periods of traumatic spinal cord disease on the basis of assessment of the dynamics of content neurospecific proteins in serum affected. Material and Methods. Content of neurospecific proteins in the blood serum has been studied by enzyme immunoassay in 40 patients with spinal cord injuries. Results. Dynamics and quantitative changes in the content of chronometric neurospecific proteins in serum of patients in acute and early periods of traumatic spinal cord disease is characterized by two-phase increase in the concentration CNTF; monotonic increase in the content of NT-3 in all periods of observation; biphasic increase in the levels of NT-4 to 1-4th and 14-th day from the date of injury. Conclusion. Complex research of neurospecific levels of proteins in the serum allows one to evaluate selectively the individual components of the process of regeneration of nerve tissue in acute and early periods of traumatic spinal cord disease.

Correction of immune disorders in patients with malignant tumors at level of craniovertebral junction and upper cervical spine

Year: 2013, volume 9 Issue: №2 Pages: 295-301

Authors: Bazhanov S.P., Uljanov V.Yu., Norkin I.A., Gulyaev D.A.
Organization: Russian Scientific Research Institute of Neurosurgery n.a. Professor A. L. Polenov
Summary:

Objective: To study the cellular and humoral immunity in patients with malignant tumors of the upper cervical spine. Material and methods: The study included 22 patients with malignant tumors of the craniovertebral junction and upper cervical spine. To assess the function of the immune system the methods of population and subpopulation immuno-phenotyping of peripheral blood lymphocytes have been applied. Cytokine parameters and functional status (cytotoxic) activity of NK-cells have been studied using immunofermental methods. The indices have been presented in absolute and relative terms. All the patients have been subjected to the adjuvant therapy. Results: Correction of cellular immunity has led to significant increase in CD3 + (T-lymphocytes) and CD3 + CD8 + (T-killers). Cytokine levels in the groups studied in the dynamics have not been significantly altered. The changes of cytotoxic (functional) activity of NK-cells in the first group after the combined treatment have been considered to be higher than before the treatment. Cytotoxic index of (functional) activity of NK-cells in the second group under the study after the combined treatment has been determined to be lower than before the treatment. Conclusion: It has been found out that the application of complex treatment accompanied by immunotropic therapy may positively influence the immune status.

Cytological evaluation and prediction of progression of acute erosive ulcered lesions of upper parts of gastrointestinal tract in acute and early periods of cerebrospinal trauma

Year: 2010, volume 6 Issue: №3 Pages: 701-703
Heading: Traumatology and Orthopedics Article type: Original article
Authors: Norkin I.A., Ulyanov V.Yu., Konyuchenko E.A.
Organization: Saratov Scientific Research Institute of Traumatology and Orthopedics
Summary:

80 cytological preparations derived by fibrogastroduodenoscopy from 20 patients with cerebrospinal trauma at cervical part level served as the research subject. Dynamics of the progression of acute erosive ulcered lesions of mucous membrane of the upper parts of the gastrointestinal tract was studied on the basis of the cytological analyses of mucous membrane biopsy materials. In the course of our work we used endoscopic (fibrogastroduodenoscopy) and cytological research methods. Cytological analyses of mucous membrane biopsy materials were carried out on the 7th, 14th, 21st and 28th day. Biopsy material cellular composition was evaluated on the grounds of the calculation of neutrophilic leukocytes and epithelial cells with the use of an immersion objective. In so doing we registered neutrophilic leukocyte number for 100 cells and determined neutrophilic and epithelial index. Monitoring of neutrophilic leukocyte number enables to determine presence or absence of inflammatory changes in stomach mucous membrane and duodenum in different periods of cerebrospinal trauma
