Anatomical Variations of the Sciatic Nerve Exit from the Pelvis and Its Relationship with the Piriformis Muscle: A Cadaveric Study.

Background: The sciatic nerve (SN) is the widest nerve of the human body that exits the pelvis through the greater sciatic foramen, usually below the piriformis muscle (PM), and descends between the greater trochanter of the femur and ischial tuberosity of the pelvis to the knee. The aim of this paper is to examine and identify the SN variations in relation to the PM, its prevalence, pattern, and course.

Methods: A prospective-descriptive cross-sectional study was carried out to determine the frequency of anatomical variations in the exit of the SN in relation with the PM in 20 anatomical bodies (corpses) of both genders, in equal numbers.

Anatomical Variations of the Median Nerve: A Cadaveric Study.

Objectives: Variations in the morphological anatomy of the median nerve such as formation, distribution, and communication have been well documented. All these variations should be taken into account when practicing any surgical approach for the treatment of injuries affecting the median nerve. Furthermore, they are of the utmost importance for interpretation of the clinical presentation.

[Validation of the Russian version of the Fugl-Meyer Assessment of Physical Performance for assessment of patients with post-stroke paresis].

Objective: To perform linguistic and cultural adaptation of the Fugl-Meyer Assessment of Physical Performance.

Materials And Methods: The study for assessment of psychometric properties included 53 post-stroke patients with neurological deficit presented by hemiparesis of different severity. The patients were assessed twice: at admission and after 14 days of treatment and rehabilitation procedures.

[INFLUENCE OF TITANIUM COATING ON THE BIOCOMPATIBILITY OF POLYPROPYLENE IMPLANTS].

Comparative analysis of the proliferative activity of inflammatory cells and distribution of collagen types I and III was carried out around the net materials of polypropylene and titanium coating polypropylene using im- munohistochemical method and polarization microscopy. Experimental modeling of implanted mesh material were made in the soft tissues of the lumbar region of rats. On the 7th postoperative day, quantitative analysis of proliferating cells delected using antibodies to the Ki-67 protein showed, a significant decrease (p < 0.

[A new view on the problem of nonneoplastic stenosis of the major duodenal papilla. Results of a prospective investigation].

The article contains results of a continuous prospective investigation of the normal course of the major duodenal papilla stenosis in 167 patients. It was revealed that the course of the disease was benign, pain syndrome became inconsiderable in the course of time, the degree of changes in biochemical analysis of blood was not significant. The development of complications (choledocholithiasis, acute pancreatitis, jaundice) was noted in 6-14% of the patients, depending on the presence or absence of GID.

[Gastric carcinoid--modern approaches to diagnosis and treatment].

Gastric carcinoid tumors are rare, but are increasing in incidence. This article reviews what is known about the classification, epidemiology, tumor pathogenesis and management of patients. Additionally we present the results of our own 10-years observation after endoscopic and surgery treatment of this tumors.

[Barrett's esophagus: endoscopic and immunomorphological parallels].

Unlabelled: Barrett esophagus is the most serious sequela of the gastroesophageal reflux disease being an obligate precancer with a high index of the neoplastic transformation as to an adenocarcinoma esophagus.

The Purpose Of The Paper: To reveal the extent of the susceptibility to oncogenesis of the Barrett esophagus-patients and to determine high-risk groups.

Materials And Methods: Our paper has shown the examination results of the 55 Barrett esophagus-patients (29 women and 26 men at the age of 39 to 62 years old), including 40 intestinal metaplasia-patients and 15 patients of the intestinal metaplasia + dysplasia of long clinical course given corresponding correcting cure.

[Analysis of efficacy of extensive systematic transperineal TRUS-guided cor biopsy of the prostate].

The paper presents the technique of extensive systemic transperineal TRUS-guided cor biopsy of the prostate. Some aspects of the patients' safety and quality of biopsy cores are considered. The analysis of TNM stages of the detected cancers (55 cases out of 142 patients who have undergone systemic biopsy) showed 65.

[Morphologic criteria of the adaptation of the vascular bed of the myocardial ventricles in acute massive embolism of the pulmonary arteries in an experiment].

Acute massive pulmonary embolism was induced in 94 random-bred dogs. There were 3 groups of the time control (0, 1 and 6 hrs) and 4 experimental groups (1- and 6-hrs compensated, 1- and 6-hrs decompensated). Favorable signs of the vascular adaptation: moderate arterial plasmorrhagia; lack of blood stasis, heterogeneity of metabolic profiles of arteries; prevalence of anaerobic glycolysis; some prevalence of catabolic reactions over anabolic reactions.

[The sympathetic innervation of the myocardium and its damage in acute massive pulmonary embolism].

The state of the adrenergic heart innervation and injuries of right (RV) and left (LV) ventricles in experimental massive embolism of pulmonary arteries (MEPA) were studied in 62 dogs under conditions of the intact thorax and natural respiration. The degree of focal myocardial injuries depended upon the density of the sympathetic innervation: when the density of adrenergic nerves (AN) was high the number of injuries decreased. Hypercatecholaminemia developing at the early period of MEPA has a cardiotoxic effect, more pronounced in dogs with decompensation.

[The sympathetic-adrenal system in experimental massive pulmonary embolism].

The density of adrenergic nervous plexus in ventricular myocardium, the concentration of catecholamines in blood and in adrenal medulla were studied on 24 dogs with acute massive pulmonary embolism (MPE) and also on 13 control dogs. Moderate and shortterm activation of adrenal system took place in control group. During the first hour of MPE the activation of both adrenal and mediator systems was revealed.
