Evaluation of the efficiency of simultaneous rigid fixing and interspinous stabilization in patients with degenerative diseases of the lumbar spine

Summary:

Purpose: to assess the effectiveness of simultaneous rigid fixation and interspinous stabilization in patients with degenerative diseases of the lumbar spine. Material and Methods. The study included 216 patients with degenerative diseases of the lumbar spine, who in 109 cases underwent isolated rigid fixation, and in 107 cases, additional simultaneous interspecific stabilization. Results. When compared with the group of isolated rigid fixation, when conducting an additional simultaneous interspinous stabilization of the adjacent segment, lower indices of the level of pain syndrome and better functional status were noted. The total number of postoperative complications in the first group is 17.4%, in the second 5.6% (p=0.02). According to the instrumental data, a statistically significantly lower degeneration of the adjacent segment in group II (p<0.001) was noted, while in 11 group I patients additional decompression-stabilizing interventions at the adjacent level were performed. Conclusion. Simultaneous rigid fixation with the installation of an interspinous stabilizer at an adjacent level in the treatment of patients with degenerative diseases of the lumbar spine can significantly reduce the level of pain, improve functional status and also protect the adjacent segment from the progression of the degenerative process in it and reduce the number of repeated surgical interventions.

Hormonal and lipid imbalances in the formation of myopic chorioretinal neovascularization in women

Year: 2019, volume 15 Issue: №2 Pages: 447-451
Heading: Ophtalmology Article type: Original article

Organization: Irkutsk State Medical University, The S. Fyodorov Eye Microsurgery Federal State Institution
Summary:

Purpose: to determine the role of hormonal and lipid imbalance in the formation of myopic chorioretinal neovascularization in women. Material and Methods. The frst clinical group includes the results of the study of patients with the active form of myopic chorioretinal neovascularization, the second — the results of the study of their paired eyes. The control groups were formed separately. Ophthalmologic and somatic status of all patients and people in the control groups were thoroughly examined. Results. An increase in the level of prolactin to 501.7±28.2 mlU/ml was established, in the control group to 272.9±33.4 mlU/ml, the level of follicle-stimulating hormone 13±0.1 mlU/ml, the control group 4,6±1.2 mlU/ml. The concentration of estradiol is reduced 35.2±3.1 pg/l, progesterone 2.8±0.1 nmol/l, compared to the control group 66.8±8.1 and 6.2±1.1 nmol/l respectively. An increase in the level of acute-phase proteins was revealed: fibrinogen 3.8 (14.0±0.5) and C-reactive protein 2 times (5.72±2.30) compared with the control group 3.6±0.5 and 2.5±0.7. Increased lipoprotein level (a) 50.2±1.2 g/l and ApoB/ApoA 0.6±0.1 compared with the control group 9.1±1.1 et 0.4±0.1 g/l. Conclusion. The fndings confrm the pathogenetic signifcance of systemic risk factors in the development of choroidal dysfunction and, as a

Lipid peroxidation and glutathione antiox-idant protection in patients with an exacerbation of chronic pancreatitis

Year: 2013, volume 9 Issue: №2 Pages: 259-262
Heading: Internal Diseases Article type: Original article
Authors: Merinova N.I., Kozlova N.М., Kolesnichenko L.S., Suslova A.I., Leonova Z.A.
Organization: Irkutsk State Medical University
Summary:

Aim: to assess the levels of lipid peroxidation (LPO) products of malondialdehyde (MDA) and glutathione system in patients with the exacerbation of chronic pancreatitis (CP). Material and Methods: 80 patients with exacerbation of CP and 23 controls have been investigated. The level of reduced glutathione (GSH) and activity of enzymes of glutathione reductase (GR), glutathione transferase (GT), glutathione peroxidase (GP) have been determined in plasma and erythrocytes, while the MDA has been studied in plasma. Results: The MDA levels in plasma were higher in CP patients as against the values of the controls. The MDA level correlated positively with intensity of pain. Increased GSH concentration and activity of GT were revealed in plasma. In the erythrocytes reduction in GP activity and GSH concentration were determined. Conclusion: In the exacerbation of chronic pancreatitis lipid peroxidation and reduced antioxidant protection have been activated.

Erythropoietin in patients with type 1 diabetes (review)

Year: 2012, volume 8 Issue: №1 Pages: 159-163
Heading: Endocrinology Article type: Review
Authors: Khantakova Е.А., Khamnueva L.Yu.
Organization: Irkutsk State Medical University
Summary:

The article analyzes the literature on the issue of regulation of erythropoietin in patients with type 1 diabetes. The connection between the secretion of erythropoietin disturbance with the development and progression of diabetes complications has been observed. Various pleiotropic effects of erythropoietin have been considered
