There are present near results of X - ray endovascular hemostasis in patients suffering from malignant neoplasm of rectosigmoid colon and rectum complicated by bleeding. Patients were divided into basic group (n=16) where the X - ray-endovascular hemostasis was performed and control group (17 patients) where the conservative methods of hemostasis were used. For angiography there was used X-raysurgical complex “GE INNOVA 4100” (General Electric, USA) and ”SHIMADZU” (Shimadzu Corporation, Japan). After preformed hemostasis, the patients of the control and basic groups for rectal cancer were undergone to preoperative radiotherapy, then radical surgery, for rectosigmoid cancer - surgical treatment. The quantity, volume of donor blood products in the treatment ofpatients of the control group were used in a significantly greater extent (p

Aim. A definition and systematisation of sigmoid diverticulitis semiotics in a comprehensive ultrasonic check-up for early illness diagnosis.Materials and methods. Ultrasound examination data on 64 patients with sigmoid diverticulum have been analysed. The primary visit reason was recurrent varying-intensity pain in left abdominal quadrant, unstable stool and flatulence. The patients were 28 (43.75%) men and 36 (56.25%) women aged 38–85 years, mean age 55.6 years; 31 (48.44%) were diagnosed with diverticulitis. We used the HD15 (Philips, the Netherlands), HS 60 (Samsung, South Korea) and Hi Vision Preirus (Hitachi, Japan) ultrasound instruments equipped with convex and intracavitary microconvex 2–12 MHz linear transducers. Patients were examined on an empty stomach and unprepared intestine. Colon and rectum were explored at different approaches, transabdominally, transperineally, transrectally and transvaginallyResults. The findings laid out a more elaborated ultrasound semiotics of diverticulitis. Ultrasound check-up enables a reliable estimation of blood supply and peristalsis, colonic wall thickness and layers, presence of asymptomatic diverticula, signs of acute diverticulitis (pain on sensor touch, mesocolic tissue infiltration, presence of faecal calculi and gas in diverticulum, peridiverticulitis) and other complications of diverticular disease (fistulae, abscess or peritonitis), as well as a consistent differential instrumental diagnosis of other organ illnesses.Conclusion. Ultrasound is an indispensable supplement in clinical diagnosis of diverticula, diverticulitis and their complications in the cases when other methods like X-ray, CT or colonoscopy are contraindicated.

Although fiberoptic examination of the colon is nowdays considered to be safe procedure, endoscopic perforation remains rare, but serious and potentially life threatening complication. General incidence od diagnostic and interventional perforations of colon ranges, according to the literature between 0.1- 0.9%, or for diagnostic procedure about 0.17%, and for interventional 0.41%, with general mortality rate of 0,006%. In spite of the general trend for diminishing this occdurence, it is necessary to compare various experiences in order to achieve an algorrhithm of early diagnostic and the way of the surgical management of this particular kind of perforation. The aim of this work is to present the experience in 1995-2004 period, upon 7 (0,12%) cases of surgically treated perforations of colon after 5,680 performed diagnostic colonoscopies. In all 7 cases the reason for perforation was not basically pathologiocal process. 4 cases of perforations were recognized immediately, and they were managed by direct suture of the perforation. In 3 cases diagnosis was late from 1 to 3 days, and two-step operative procedure was performed in septic condition. Subjective and clinical signs of perforations were not always uniform, but in all 7 cases there were clear X-ray signs of free intraabdominal air. Surgical treatment was successful, and without deaths. In the algorrhithm of surgical diagnostic and procedure, the same principles and criteria used for civilian injuries of colon are to be used.

Introduction. Ingestion of foreign body is one of the most complex and serious emergency conditions to diagnose. Accidental ingestion is more frequent in children than in adults, whereas intentional ingestion is usually found in cases of mental disorders, prisoners, attempted suicides, and in persons with intellectual disabilities. Case report. Glass ingestion is very rare and it is very difficult to predict the consequences of its passing through the gastrointestinal tract. We report a case of accidental swallowing of a large quantity of glass pieces in the ascending colon and rectum diagnosed by abdominal X-ray. The patient did not have any signs of perforation. An expectant attitude was taken, and the elimination occurred naturally.

AbstractUsing a new ID hybrid model of the electron bombardment in flare loops, we study not only the evolution of densities, plasma velocities and temperatures in the loop, but also the temporal and spatial evolution of hard X-ray emission. In the present paper a continuous bombardment by electrons isotropically accelerated at the top of flare loop with a power-law injection distribution function is considered. The computations include the effects of the return-current that reduces significantly the depth of the chromospheric layer which is evaporated. The present modelling is made with superthermal electron parameters corresponding to the classical resistivity regime for an input energy flux of superthermal electrons of 109erg cm−2s−1. It was found that due to the electron bombardment the two chromospheric evaporation waves are generated at both feet of the loop and they propagate up to the top, where they collide and cause temporary density and hard X-ray enhancements.

The development of the physics of the solar atmosphere during the last 50 years has been greatly influenced by the increasing capability of observations made from space. Access to images and spectra of the hotter plasma in the UV, XUV and X-ray regions provided a major advance over the few coronal forbidden lines seen in the visible and enabled the cooler chromospheric and photospheric plasma to be seen in its proper perspective, as part of a total system. In this way space observations have stimulated new and important advances, not only in space but also in ground-based observations and theoretical modelling, so that today we find a well-balanced harmony between the three techniques.

AbstractOver the last twenty years, orbiting coronagraphs have vastly increased the amount of observational material for the whitelight corona. Spanning almost two solar cycles, and augmented by ground-based K-coronameter, emission-line, and eclipse observations, these data allow us to assess,inter alia: the typical and atypical behavior of the corona; how the corona evolves on time scales from minutes to a decade; and (in some respects) the relation between photospheric, coronal, and interplanetary features. This talk will review recent results on these three topics. A remark or two will attempt to relate the whitelight corona between 1.5 and 6 R⊙to the corona seen at lower altitudes in soft X-rays (e.g., with Yohkoh). The whitelight emission depends only on integrated electron density independent of temperature, whereas the soft X-ray emission depends upon the integral of electron density squared times a temperature function. The properties of coronal mass ejections (CMEs) will be reviewed briefly and their relationships to other solar and interplanetary phenomena will be noted.

AbstractEmission mechanisms of the iron Kα-lines in X-ray binaries are discussed in relation with the characteristic temperature Txof continuum radiation thereof. The 6.7 keV line is ascribed to radiative recombination followed by cascades in a corona of ∼ 100 eV formed above the accretion disk. This mechanism is attained for Tx≲ 10 keV as observed for low mass X-ray binaries. The 6.4 keV line observed for binary X-ray pulsars with Tx> 10 keV is likely due to fluorescence outside the He II ionization front.
