Migration of foreign bodies through the urinary system (clinical cases)

Introduction. Migration of implantable materials is a rare but significant complication of surgical interventions in urological practice. Objective: to present an analysis of two clinical cases of unusual migration of fixing Capron (nylon) structures in the urinary system. Materials and methods. Two clinical observations are described: a case of migration of a fixing Capron suture into the kidney parenchyma after nephropexy and a case of transurethral migration of a supporting loop after surgery for urinary incontinence. Diagnostics was carried out using clinical examination, ultrasound imaging, computed tomography, and endoscopic methods. Results. In the first case, the migration of the Capron suture into the kidney parenchyma was successfully resolved through laparoscopic removal of the structure and replacement with a polypropylene one. In the second case, spontaneous transurethral migration of the fixing loop occurred without the development of stricture and with preservation of the functional result of the operation. Conclusion. The presented observations demonstrate the possibility of gradual migration of Capron structures through the tissues of the urinary system without developing serious complications. These cases emphasize the importance of suture material selection in urological operations and the need for long-term patient monitoring

A clinical case of recurrent pain syndrome due to hiatal hernia, occurring under the guise of acute pancreatitis

Introduction. In the structure of urgent pathology diseases, the leading place belongs to acute pancreatitis, which is the third most common after acute appendicitis and acute cholecystitis. According to statistical data, mild forms of acute pancreatitis account for 84.7%.The aim of the work is to demonstrate a clinical case of recurrent abdominal syndrome occurring under the gastroesophageal mask of acute pancreatitis in order to identify hernia of the esophageal orifice of the diaphragm using the developed diagnostic algorithm.Object and methods. Patient M., 56 years old, repeatedly sought medical help with recurrent abdominal syndrome in a network of polyclinics, as well as a hospital providing emergency specialized medical care. Results and discussion. Against the background of conservative treatment, the patient had a short-term positive dynamics characteristic of a mild form of acute pancreatitis. After taking the patient to the dispensary and conducting an indepth diagnostic examination according to the algorithm developed by our group of researchers, gastroesophageal reflux disease, hernia of the esophageal orifice of the diaphragm was detected.Conclusion. Patients with recurrent abdominal pain syndrome need dispensary observation on an outpatient basis to identify other pathology occurring under the guise of acute pancreatitis and adequate treatment

Mapping and spatial-temporal assessment of gully density in the Middle Volga region, Russia

© 2018 John Wiley & Sons, Ltd. A large-scale mapping of gully density was carried out for the Middle Volga region of the Russian Plain (188 000 km2) based on the interpretation of aerial photographs (scale 1:17 000; surveys undertaken during 1956–1970). In addition, spatial-temporal dynamic of gully density were assessed for some parts of the study area (the Udmurt Republic and the Mesha and Ulema River basins of Tatarstan), based on the interpretation of aerial photographs (survey 1986–1991) and high resolution satellite images (2012–2015). Information on factors potentially controlling gully formation and development were collected and a geographic information system (GIS) analysis was conducted. Results show the strong development of gullies in the study area over the 1956–1970 period with an average gully density of 0.21 km km−2. For the Udmurt region, we found that gully densities varied little in the period 1956–1986, during which the total active gully length reduced with only 2%. This period was characterized by low variable climatic conditions and a stable fraction of arable land with a relatively continuous crop rotation system. However, gully dynamics seems to have changed more strongly during recent decades. We found a strong (order of magnitude) reduction in active gully density for the period 2010–2015 as compared to 1986–1991. The main reason for this is likely the increasing winter air temperatures. This leads to a significant reduction in surface runoff during spring as a result of snowmelt. Nonetheless, in some regions (i.e. the Udmurt Republic in the taiga zone), the abandonment of arable land after 1991 likely plays a significant role. Likewise, a decline in the frequency of extreme rainfall events (> 50 mm) may have played a role. All of these factors contribute to a reduction of surface runoff to the gullies and their subsequent stabilization. © 2018 John Wiley & Sons, Ltd.status: publishe

RESTORATION OF MAINTENACE CONDITIONS OF BRICK WALLS

The issue of selection procedure of brick walls bearing capacity restoration means is considered in the article. As the result of maintenance conditions complex surveying certain cases of crack formation caused by a number of structural faults have been discovered. A contrastive analysis of restoration techniques is presented from the standpoint of economic efficiency and time expenditure on work execution.</jats:p
