Transforaminal Endoscopic Discectomy Under General and Local Anesthesia: A Single-Center Study.

Percutaneous spinal endoscopy is used for the treatment of disorders of the lumbar spine, as it has several advantages over traditional surgical methods. The performance of percutaneous spinal endoscopy is not possible without applying anesthesia methods. Two types (local and general) of anesthesia are used for percutaneous spinal endoscopy.

Minimally Invasive Posterolateral Approach for Surgical Resection of Dumbbell Tumors of the Lumbar Spine.

Minimally invasive spine surgery (MISS) has many advantages over traditional open surgical procedures that can be conducted for the therapy of different diseases of the spine. MISS provide many prospective advantages such as, for example, small incisions, less damage to soft tissues, early activation of patients, and a shorter postoperative hospital stay. The aim of the study was to evaluate institutional experience with Dumbbell tumors and metastatic lesions of the lumbar spine and compare it with traditional open surgical resection of this type of tumors.

Thoracic Spinal Stability and Motion Behavior Are Affected by the Length of Posterior Instrumentation After Vertebral Body Replacement, but Not by the Surgical Approach Type: An Study With Entire Rib Cage Specimens.

Spinal tumors and unstable vertebral body fractures usually require surgical treatment including vertebral body replacement. Regarding primary stability, however, the best possible treatment depends on the spinal region. The purpose of this study was to evaluate the effects of instrumentation length and approach size on thoracic spinal stability including the entire rib cage.

In vitro comparison of personalized 3D printed versus standard expandable titanium vertebral body replacement implants in the mid-thoracic spine using entire rib cage specimens.

Background: Expandable titanium implants have proven their suitability as vertebral body replacement device in several clinical and biomechanical studies. Potential stabilizing features of personalized 3D printed titanium devices, however, have never been explored. This in vitro study aimed to prove their equivalence regarding primary stability and three-dimensional motion behavior in the mid-thoracic spine including the entire rib cage.

[The immune system indices of patients with acute recurrent bronchitis].

A study of the immune system in 30 patients with acute recurrent bronchitis revealed disorders of the cellular and humoral immunity manifested in a reduction of the number of T-lymphocytes and theophylline-resistant T-cells. There was also a reduction of A and G immunoglobulins in the blood serum. These disorders remained also after normalization of the clinical picture of the disease evidencing the necessity to include immunostimulating agents in the complex treatment of patients with acute recurrent bronchitis.

[Comparative evaluation of the effects of isoptin and obsidan on central and cerebral hemodynamics in patients with hypertension during physical exercise].

Isoptin and obsidan were demonstrated to cause a significant increase in exercise tolerance in patients with Stages I and II hypertensive disease. The response of blood pressure to isoptin and obsidan was virtually identical, yet isoptin acted longer. When obsidan was administered, there was a decrease in specific peripheral vascular resistance with a stepwise elevation of blood pressure, whereas isoptin promoted its slight rise with maximally elevated blood pressure.

[Autoregulation of the cerebral blood flow in normo- and hypertensive rats under beta-adrenoreceptor blockade].

A disorder in the autoregulation of cerebral blood flow due to a drop of arterial blood pressure (shift to the right) occurred earlier in hypotensive rats than in normotensive ones. A beta-adrenergic blockade (obsidan) improved the autoregulation (shift to the left) in both normo- and hypertensive animals.

[Current possibilities and prospects of using gas lasers in medicine. Laser therapy].

Local laser radiation of human organism for therapeutical purposes can be looked upon as an efficient and controlled method of normalization of functioning of a number of organs. Laser units designed on the basis of industrial gas lasers are used on a large scale for treatment of vascular diseases and related ischemias in various parts of the human body.

[Effect of klofenil on the hemodynamic and autonomic nervous system functions in patients with hypertensive disease].

The degree of hemodynamic and vegetative changes is determined to a great extent by the time of clopheline intake. The maximal changes in the sympathetic activity at rest and during active orthostasis were revealed in the morning hours and in the second half of the day, the minimal ones--in the afternoon hours. The hemodynamic changes were most pronounced at 12 o'clock and minimal at 7 o'clock.

[Current potentials and outlook for the use of gas lasers in medicine. Laser surgery].

Gas lasers are now in common use in clinical practice due to such advantages as a wide range of wavelengths, high spatial coherence, diversity of power radiations, and adequate reliability. Continuous CO2 lasers and pulse Cu and CO2 lasers recently produced on the industrial basis offer new opportunities to improve the quality of laser surgical interventions, cutting biological tissues with high blood supply and lower water content (bones, fat, burns, etc.), visceral surgery via endoscopes.

[Transfusiologic technics for the prevention and treatment of acute renal failure in the DIC syndrome in children].

Experiences with the treatment of 38 children with acute renal insufficiency owing to the hemolytico-uremic syndrome suggest that the combination of hemolysis and hemosorption at early stages of the disease brings about a rapid elimination of uremic toxins, "middle" molecules included. The authors consider the content of the "middle" molecules in the plasma to be the most informative index showing the severity of the condition, hemosorption being the most effective method against endotoxicosis.

[Changes in suspension stability of donor conserved blood in contact with carbon adsorbents].

A possibility is shown to normalize the suspension stability of donor long-term conserved blood when passing it through carbon adsorbents of a developed porous structure which are well compatible with blood. Relationship is established between a fall in the concentration of low-molecular acid products of metabolism as well as of conserved blood protein compounds due to interaction with the surface of carbon sorbents and an increase in electrophorectical erythrocyte mobility, and some decrease in aggregation and viscosity of blood.

[Physiological assessment of the method of autohemoperfusion through activated carbon].

The results of study of the sorption properties of phenolformaldehide-activated coal in respect of several physiologically active substances from the physiological saline under static conditoins and under conditions of autohemoperfusion of the limb vessels in experimental animals are presented. Phenolformaldehide-activated coal proved to sorb actively serotonin, adrenaline and noradrenaline, and--to a lesser extent--histamine from physiological saline. Serotonin, adrenaline, noradrenaline, and acetylcholine are sorbed well, histamine--less, papaverine--very weakly from the flowing blood.

[Means of positioning fragments by smoothly controlled stresses].

In fractures or luxations muscles being in the state of retraction or contracture and with lost capacity to spontaneous relaxation and lengthening may relaxe and lengthen as a result of application of relatively small smoothly controlled stresses incessantly lessening along with muscle lengthening. The long-term experience with the use of the elaborated method in the clinic of general surgery and hospitals of the Gorky City proved convincingly great opportunities of nonoperative treatment of fractures and reduction of dislocations.
