Published: July 2015

AbstractThe issue of the quality of life considering patients with a temporary or permanent intestinal stoma, as well as the necessity for chronic parenteral nutrition at home remain a poorly understood problem. Daily care of the intestinal stoma and the need to comply with sterile procedures required for parenteral nutrition require such patients to commit their time, which secondarily is associated with the broad aspects of social and personal life.The aim of the study was to analyse the quality of life considering patients with intestinal stomas subjected to chronic parenteral nutrition, before and after gastrointestinal tract continuity restoration.Material and methods. The survey was conducted between May and July, 2014 on a group of 71 patients (33 female and 38 male) who were under the care of the Department of General Surgery and Clinical Nutrition, Warsaw Medical University, operated during the period between 2007 and July, 2014 with a present stoma (32 patients - 45%), as well as after stoma closure (39 patients - 55%). The analysed questionnaire contained 31 questions, and the SF-36 questionnaire was additionally used, determining the quality of life.Results. Analysis of the study material showed differences in the quality of life, considering three most important determinants. Significantly worse assessment of the quality of life was reported by patients with a stoma and subject to intravenous nutrition (83.2±30.5), as compared to those after stoma closure subject to normal nutrition (52.3±33.8). Based on the SF-36 questionnaire differences between patients with a stoma and those without amounted to t(69)=2.84 (p=0.006) demonstrating that those with a stoma reported a lower quality of life. Analysis between younger and older patients, based on the SF-36 questionnaire (t(62.87)=2.49; p=0.016) showed that younger patients achieved lower results, considering dissatisfaction with life (61.55±27.5), as compared to the elderly (80.8±36.9).Conclusions. The group of patients without a stoma seem to be more independent- the vast majority do not use the help of family members (43.6%), or friends (64.1%). Patients with a stoma more often withdraw from social life. The factor that mostly reduces the quality of life is the presence of a stoma, which impairs daily functioning a lot more than the sterile procedures associated with parenteral nutrition. All patients after stoma closure consider that their overall functioning has significantly improved.

AbstractStoma is an intestinal fistula created in emergency or by elective indications, and it is done to drain out the digestive tract content. In some patients there is a disturbance passage of gastric contents through the stoma, which may take the form of chronic constipation or even periodic subileus that will sooner or later require surgical treatment.The aim of the study was the assessment of the causes and method of treatment of constipation in patients with intestinal stoma.Material and methods. A total of 331 patients with stoma followed by Ostomy and Proctology Outpatient Clinic were included in the study in the years 2011-2014. The study included 146 women and 185 men and the average age was 61.3 ± 12.7 years. Within the entire froup, 273 patients had the end stoma performed whereas in 58 patients the loop stoma was created. The highest percentage of patients were the ones with diverticulosis and colorectal cancer, i.e. 132 and 114 patients respectively. A stoma was created in 35 patients due to inflammatory bowel disease (IBD), in 23 patients because of cancer, in 14 as a result of injuries and in 13 due to rectovaginal fistula.Results. Out of the entire group subject to study (331 patients) 93 patients (28.1%) suffered from constipation. 50 patients with constipation required surgical intervention. The most common indication for surgical treatment was the parastomal hernia (36 patients, 72%), other indications were the narrowing of the stoma (5 patients, 10%), its collapse (6 patients, 12%) or prolapse (3 patients, 6%). Parastomal hernia was responsible for 84% of constipation within the stoma and 86.1% were treated with laparotomy (31 out of 36 patients). Other causes of constipation were the stomal stenoses (5 patients), collapse of the stoma (6 patients) and stomal prolapse (3 patients). All patients were treated surgically with a good final result.Conclusions. Constipation associated with dysfunction of the stoma in most cases should be treated surgically. Parastomal hernia is the most common cause of constipation in the stoma. Treatment should be performed in due time because of the possibility of developing complications, especially dangerous one is a strangulated parastomal hernia and ischemia of stoma.
Multiannual abdominal pain complicated by obstruction of the gastrointestinal tract in the course of cystic form of mesenteric lymhangioma of the small intestine

Published: July 2015

AbstractLymphangiomas constitute a group of very rare diseases and occur with a frequency of 1/250,000 to 1/20,000 of hospitalizations. Even though they are benign lesions, their complications may turn into a life-threatening condition. They usually occur in children (90%), they are either congenital or they appear before the child’s second birthday. Occassionally they are found in adults.Lymphangiomas are usually localized around neck, but also near armpits and in the groin area. Less than 1% of lymphagiomas are detected in the retroperitoneal space and intestinal mesentery. Vascular lesions derived from lymphatic vessels can be divided into ordinary ones, usually known as capillary, cavernous, and cystic. The cystic tumor (lymphangioma mesenteri) is the least common. It occurs mostly in the retroperitoneal space, mesentery of the colon, or extremely rarely in the mesentery of the small intestine. Preoperative diagnosis is difficult due to non-specific clinical symptoms and noncharacteristic image in the diagnostic tests. Lymphangioma complications, such as intestinal obstruction or perforation, and persistent pain, are the cause of exploratory laparotomy. Final diagnosis requires microscopic examination of material collected during an operation.This article presented the case of a 40-year-old female, operated due to the obstruction of the gastrointestinal tract, in whose case the lymphangioma was recognised in postoperative histopathological examination of the tumor from the jejunal mesentery. Since patients with these tumors have good chances of complete recovery - if there are no serious complications - it appears that the optimal therapeutic procedure should be early surgery, which reduces the possibility of complications.
Neurogenic pulmonary edema induced by subarachnoid hemorrhage:; case report on diagnostic and therapeutic implications
Authors: Weiss Guenter , Meyer Frank 
Published: July 2015

AbstractAn exemplary rare case of neurogenic pulmonary edema induced by intracranial hemorrhage was reported including diagnostic and therapeutic implications as well as management recommendations. A 35-year old man who was treated first by a neurosurgical approach because of a subarachnoid hemorrhage (bore hole trepanation) and subsequently on a surgical intensive care unit because of severe postoperative hemodynamic, cardiocirculatory, and pulmonary disruptions. To monitor cardiopulmonary condition and treatment effects, a Swan-Ganz catheter was placed in the pulmonary artery, since after trepanation, a critical cardiopulmonary status developed during postoperative mechanical ventilation and catecholamine administration. This condition was indicated by neurogenic pulmonary edema detected by control chest X-ray film and high oxygen load in the inspiratory air required for sufficient arterial oxygenation. After use of high positive end-exspiratory pressure (PEEP) (initially directed against neurogenic lesion), adaptation of initial dobutamine doses, initiation of norepinephrine administration, and substitution of fluids, the patient's blood pressure finally rose sufficiently to sustain regular cerebral blood perfusion and achieve better arterial oxygenation. Thus, the patient‘s cardiopulmonary condition stabilized and temporary cardiac insufficiency could be overcome. Subsequently, it became possible to decrease PEEP according to requirements to prevent or limit cerebral edema and to diminish catecholamine doses.

On the Modelling of Vertical Permeability Barriers in Single-Well Simulation Models;a Hybrid Approach
Authors: Haldorsen H. H. 
Published: July 2015

ABSTRACT
This paper presents stochastic descriptive schemes for explicit and implicit modelling of vertical permeability barriers in single-well simulation studies. The drainage volume of the well to be simulated is first partitioned into two regions; one explicit region (termed explicit because actual barriers such as shales of varying sizes are placed within the grid) and one implicit region (termed implicit because the effects of the discontinuous shales are averaged into an effective vertical permeability). Secondly, the shales are converted into vertical transmissibility modifiers and included in the data input stream along with the effective vertical permeabilities calculated for the implicit regions.
The paper describes in detail procedures which: -Generate lateral dimensions of shales observed in a well (shale shape and length/width statistics supplied by geologists, shale positions in wells and thicknesses of shales in wells from cores and logs).-Maintain the sand/shale sequence observed in the well.-Generate additional shales in the defined explicit shale region around the well until an overall desired vertical shale density (number of shales/vertical foot) is achieved. The placement of these shales which are not "hit" by the well-bore is subject to conditioning and constraints.-Make all shales "conform" to a pre-set areal and vertical grid system.-Plot out pictures of the resulting shale descriptions.-Estimate an effective large-scale vertical permeability for use in large grid-blocks far away from the well (in the implicit region).-Convert shales into subdomains over which the vertical transmissibility between model layers K and K+1 is modified (written out to tape for direct inclusion in simulator data input stream).
The methodology developed is illustrated by applying it to a North Sea reservoir with a thin oil column sandwiched between a gas cap and an active aquifer. In this reservoir, trustworthy predictions of oil, gas and water production rates through time are of fundamental importance. In fact, the field development decision may be swayed one way or the other depending on how long the gas and water production may be suppressed (aided by shales) for a reasonably high (and sustainable) oil production rate.
Uses and Limitations of a Drillstring Tension and Torque Model To Monitor Hole Conditions
Authors: Brett J. F. , Beckett A. D. , Holt C. A. , Smith D. L. 
Published: July 2015

ABSTRACT
This paper presents the results of the application of a Tension-Torque model to directional wells drilled worldwide. The final inclination of the wells ranged from 25° to 70°, and the Tension-Torque model was effectively used in these cases to aid in planning the directional program prior to spud, monitor the wells while drilling, or to postanalyze some particular drilling problem. The examples presented are representative of the situations to which the Tension-Torque model can be routinely applied.
These examples show that the model can effectively aid the well planner in selecting the best well path, drillstring designs, casing program, and mud system prior to spud. A second set of examples shows how real time monitoring of drilling conditions, combined with model use, can develop a baseline so that deviations from expected behavior can be analyzed and explained. Appropriate action can then be taken to remedy problems before they became serious. A final set of examples is presented to show how a Tension-Torque model can be effectively used to determine the actual cause of a particular drilling problem after a well is completed. Experience gained from postanalysis of problems in this manner can be used to improve later operations.
The chief technical contributions of this paper are to compare field data with model predictions for a wide range of different inclinations, to show how torque and drag models can be used to monitor hole conditions in real time, as well as demonstrate that the tool can be used to improve the planning and postanalysis of drilling operations.
Swelling of Oil-Base Drilling Fluids Due to Dissolved Gas
Authors: O'Bryan P. L. , Bourgoyne A. T. 
Published: July 2015

ABSTRACT
A major problem associated with the use of oil-base drilling fluids is the increased difficulty of detecting gas which enters the borehole and dissolves in the drilling fluid. Previous authors have made computer-simulated comparisons between a water-base and an oil-base drilling fluid for one specific field example. However, a method is needed that will permit field personnel to quickly estimate the amount of dissolved gas that can be associated with an observed pit gain for the field conditions present. In this paper, a method is presented for estimating the swelling of oil-based drilling fluids due to dissolved gas. The method can be applied both (1) when the gas is fully miscible with the drilling fluid, and downhole mixing is limited and (2) when gas initally contacts the drilling fluid in volumes above the solution gas-mud ratio, and mixing is enhanced by the initial developement of gas bubbles.
Experimental PVT data were used to verify the calculation method presented for a range of compositions, temperatures, and pressures. The method was also verified by experiments in a 6000-foot test well.
Examples are presented showing typical computed values for swelling volumes at various depths, mud densities, and gas concentrations. Pit gain comparisons are made with water-base drilling fluids for a wide range of conditions. These examples illustrate situations in which it is difficulty to detect a gas kick in an oil-base drilling fluid.
In addition to determining the amount of the dissolved gas present in a given field situation, the method can also be used to determine the sensitivity requirements of kick-detection equipment for any specified hole geometry. The method applies to both surface and subsurface kick-detection equipment.
Acoustic Directional Surveying Instrument

Published: July 2015

ABSTRACT
A new type of acoustic detector capable of determining the direction of a noise source has been developed. Wire-line operation of this tool has been successfully carried out at bore-hole pressures greater than 70 bar. With granite transmission, directional detection of 1° – 2° accuracy, and at ranges up to 200 metres have been achieved. Detectable acoustic sources include drill-bit noise and pulses, such as sparking tool.
The sensing element of this device is a symmetric resonator whose flexural vibrational modes are readily excited by an external acoustic source. The physical principle is that the nodal angles are pinned to the acoustic propagation direction, this determining the noise direction relative to the device. The vibration pattern is measured and processed to provide such directional data. The total sensing system is encapsulated in oil which serves to receive and communicate acoustic signals.
This paper presents experimental results relating to various environments, and assesses the potential for bore-hole logging and well blow-out location.
A New Calcium-Tolerant Polymer Helps To Improve Drilling Mud Performance and Reduce Costs
Authors: Ujma K-H. W. , Plank J. P. 
Published: July 2015

ABSTRACT
Zechstein wells in Germany require water based drilling fluids with filtration control additives which are (1) extremely salt and hardness tolerant as the Calcium/Magnesium content in the mud filtrate may run up to 140,000 ppm and (2) which function in the temperature range up to at least 350°F (177°C). Use of a new sulphonated polymer filled a gap in existing fluid loss additives for high salt and high hardness environments and resulted in improved mud performance and cost savings. Major benefits cane from a synergism of the novel polymer with starch and cellulosic materials like e.g. CMC or PAC. Minor additions of the new polymer yield an average gain in thermal stability of 50°F (25°C) for starch and CMC or PAC, resp. Field experience with a combination of starch and the novel fluid loss polymer indicate a completely Calcium/Magnesium tolerant, up to 290°F (143°C) stable and inexpensive mud system. Thermal stabilization of CMC/PAC through combination with the novel polymer also was successfully field proven.
Mutual Solubility of Salts in Drilling and Completion Fluids
Authors: Kemp N. P. 
Published: July 2015

ABSTRACT
Described below are models for predicting crystallization temperatures of pure- and mixed-salt brines which can be used to calculate the solubility behavior of salt-containing fluids. The model predictions are compared to published mixing tables for heavy brine completion fluids and to crystallization temperatures measured in our laboratory. Examples are given of how the models have been used to formulate brine muds and to predict how much additional salt could be added to a produced brine mud to increase mud density without having excess solids.
Flow of Drilling Fluids Through Eccentric Annuli
Authors: Luo Y. , Peden J. M. 
Published: July 2015

ABSTRACT
The eccentric annular flow of power-law and Bingham plastic fluids is analysed in this paper using a new method in which an eccentric annulus is represented by infinite concentric annuli with variable outer, radii. For the case of power-law fluids, analytical solutions of the shear stress and velocity profiles have been obtained which are valid over the entire eccentric annulus. For Bingham plastic fluids, the profiles have been obtained at the minimum and maximum dimension positions of the eccentric annulus, which are considered to be the important positions for the analysis of cuttings transport in an inclined eccentric drilling annulus.
The results show that the local velocity and shear stress have greater magnitude in the enlarged region of an eccentric annulus than in the reduced region. In addition, like the case of concentric annular flow, the present analysis indicates that the profiles of the velocity and the magnitude of the shear stress in an eccentric annulus are not symmetric in the radial direction. Previous studies gave either unrealistic symmetric profiles or very complicated solutions.
Based on the above analysis, the effect of the eccentricity of a drilling annulus on cuttings transport is evaluated. The results of this analysis will aid in the design of drilling programmes, particularly for deviated wells, to ensure efficient transport of drilled cuttings.

Ein Architekturprojekt für ein Stadtpalais in Toulouse, das Hôtel dit de Massas, in Form von Randzeichnungen in einem Exemplar von Serlios
Extraordinario Libro : Dominique Bachelier delineavit ? Von Xavier Pagazani

Im 16. Jahrhundert waren die soziale Stellung oder das Prestige eines französischen Architekten nicht so bedeutend, dass seinem zeichnerischenWerk eine besondere Aufmerksamkeit geschenkt wurde. Deshalb sind nur wenige Skizzen und Architekturzeichnungen überliefert. Es ist also immer ein Ereignis, wenn ein solches Dokument entdeckt wird. Die Bibliothek INHA-Collections Doucet besitzt ein Exemplar des Extraordinario Libro von Sabastiano Serlio (Lyon 1551). Das Besondere daran sind Tintenzeichnungen am Textrand und auf den weißen Rückseiten der Folien. Unter den Rissen befinden sich detaillierte Skizzen eines Fensters, die vermuten lassen, das es sich um dasWerk eines Architekten handelt. Die Fenster des Hôtel dit deMassas in Toulouse (in der rue de la Dalbade Nr. 29) wurden nach genau diesen Skizzen geschaffen. Die Vergleichsanalyse der Architektur dieses Stadtpalais’, der Skizzen und der tolosanischen Architektur des 16. Jhds. lassen eine Zuschreibung zu : danach wäre Dominique Bachelier der Architekt des Hôtel de Massas und der Zeichner in Serlios Buch. Das mit Randnotizen versehene Exemplar des Extraordinario Libro gäbe uns also Einblicke in zwei intime Arbeitsweisen eines Architekten der zweiten Hälfte des 16. Jhds. : in den Rückgriff auf Serlios Buch als Grundlage eines schöpferischen Prozesses und, auf den weißen Blättern, die räumliche und zeitliche Zurschaustellung einer Architekturerfindung.
Portrait de Gogol en « toutiste » : Iliazd et Gogol

Gogol's portrait as an « everythingist » : Iliazd and Gogol
Nothing seems to connect a priori Gogol's works with any artistic avant-garde XXth century theory. The "everythingism" invented by the painter M. V. Le-Dantu and practiced by the poet Iliazd in dramaturgy proposes therefore a vision of the artistic world not far from Gogol's in his novel "The Portrait". The similarities between Le- Dantu's theory and the points of view expressed by the different voices of the Portrait's author are numerous and underlined by the references to the Gogol's Portrait in the dramas of Iliazd. As the first Russian author to have drawn attention to the art of self-taught artists, Gogol turns curiously like a distant predecessor of the modern neo-primitivists and everythingists.
