[Stagewise treatment of a patient with multifocal atherosclerosis, limb ischaemia, and surgical infection]. / Étapnoe lechenie patsienta s mul'tifokal'nym aterosklerozom pri ishemii konechnosti i khirurgicheskoi infektsii.

UNLABELLED: The authors share herein their experience in successful treatment of a male patient with multifocal atherosclerosis and lower-limb critical ischaemia complicated by erysipelas. THE AIM OF THE WORK: to show not only efficacy of iloprost (Ilomedin) used as conservative treatment in patients presenting with critical ischaemia and surgical infection in both pre- and postoperative periods in order to save the limb, but also the possibility of postponing reconstructive intervention, improving the patient's quality of life during this period, as well as shortening the duration of the postoperative period, and also to demonstrate both immediate outcomes of endovascular repair of an abdominal aortic aneurysm and remote results of comprehensive treatment for disseminated multifocal atherosclerosis with severe accompanying pathology.

Double diffractive cross-section measurement in the forward region at the LHC.

The first double diffractive cross-section measurement in the very forward region has been carried out by the TOTEM experiment at the LHC with a center-of-mass energy of sqrt[s]=7 TeV. By utilizing the very forward TOTEM tracking detectors T1 and T2, which extend up to |η|=6.5, a clean sample of double diffractive pp events was extracted. From these events, we determined the cross section σDD=(116±25) µb for events where both diffractive systems have 4.7<|η|min<6.5.

[A case of successful treatment of angioma of the middle and external ear]. / Nabliudenie uspeshnogo lecheniia rasprostranennoi angiomy srednego i naruzhnogo ukha.

A rare form of benign tumour (angioma of the middle and external ear) is described. The preoperative treatment with the use of embolization of the feeding vessel made possible surgical intervention on a practically "dry" operating field.

[Surgical treatment of fibromuscular dysplasia of renal arteries in adults].

The authors have analyzed an experience with treatment of 16 patients. All the patients had renovascular hypertension (RVH) and 3 of them had renal dysfunction. Revascularization of the kidneys (RK) was fulfilled in 11 patients by shunting (9) or prosthesis (2) of the renal arteries. In 7 patients percutaneous endovascular angioplasty (PEA) was used. There were neither complications nor lethal outcomes. Arterial pressure normalized in 7 patients and in 9 RVH was better. In the long-term period (at the average within 21 months) 14 patients were followed-up. In 3 patients having perimedial and intimal fibroplasty of RA after PEA restenoses were diagnosed. They had repeated RK. Renal function became better in 1 patient, in 2 patients there was no substantial dynamics. All shunts were passable. The analysis of the data has shown that liquidation of RVH in patients with FMD of RA has inverse dependence on its duration, and decision on the method of RK depends on the type of RA, experience of the specialists, the patients desire included.

[Percutaneous angioplasty and stenting in treatment of chronic occlusions of renal arteries].

The article presents results of examination and treatment of 14 patients aged from 46 through 79 years with chronic occlusion of one of the renal arteries in each of them and subocclusion of the contralateral renal artery in 13 patients due to atherosclerosis. At first percutaneous intraluminal angioplasty and stenting were performed in 13 out of 14 patients with stenosis of the renal artery. Then at once only percutaneous intraluminal angioplasty of the occlused renal artery was performed in 10 out of 14 patients and within 36 hours on average the implantation of stents in case of patency of the renal artery proper and its branches, according to the findings of control angiography, in these arteries with the optimal result. The percutaneous intraluminal angioplasty and stenting are relatively safe and effective methods of reestablishment of patency of the renal arteries after their chronic occlusion.

[Transjugular intrahepatic portosystemic shunt (TIPS): an experience with treatment of portal hypertension in patients with cirrhosis of the liver].

TIPS procedures have been successfully performed in 18 of 21 patients aged 34-64 (mean age 40 years) with cirrhosis of the liver with acute gastroesophageal bleedings (5) or history of bleeding episodes from gastroesophageal varices (13). The patients were classified according to Child (1964): A--4; B--8 and C--6. The portal pressure before creation of the shunt measured 17-39 (mean 28.1 +/- 7.6) mm Hg. Dilation of the hepatic tissue was performed by a balloon 10 mm in diameter and 4-6 cm long with placement of metallic endoprostheses 10-12 mm in diameter and 80 mm long. The portal pressure after anastomoses were made dropped to 6-28 (mean 20.3 +/- 5.7) mm Hg. The angiogram showed a rapid flow of the contrast medium through the portocaval anastomosis towards the right heart and no filling of the esophageal veins was seen. TIPS procedure is an effective measure to stop variceal gastroesophageal bleeding in patients with portal hypertension. The necessity of regular surveillance and reinterventions makes this approach a temporary measure to reduce hazardous consequences of gastroesophageal hemorrhages.

Omega- and Omega+ production in central Pb + Pb collisions at 40 and 158A GeV.

Results are presented on Omega production in central Pb+Pb collisions at 40 and 158A GeV beam energy. For the first time in heavy ion reactions, rapidity distributions and total yields were measured for the sum Omega(-) + Omega(+) at 40A GeV and for Omega(-) and Omega(+) separately at 158A GeV. The yields are strongly underpredicted by the string-hadronic UrQMD model but agree better with predictions from hadron gas models.

System-size dependence of strangeness production in nucleus-nucleus collisions at squareroot[sNN]=17.3 GeV.

Emission of pi+/-, K+/-, phi, and Lambda was measured in near-central C+C and Si+Si collisions at 158 AGeV beam energy. Together with earlier data for p+p, S+S, and Pb+Pb, the system-size dependence of relative strangeness production in nucleus-nucleus collisions is obtained. Its fast rise and the saturation observed at about 60 participating nucleons can be understood as the onset of the formation of coherent systems of increasing size.

[Intravascular repair in extended arterial occlusive lesions (a preliminary communication)]. / Vnutrisosudistaia rekonstruktsiia pri protiazhennykh okkliuziruiushchikh porazheniiakh arterii (predvaritel'noe soobshchenie).

Subintimal recanalization as a procedure of percutaneous vascular repair is under study now. The Regional Clinical Hospital has performed 10 procedures of subintimal angioplasty in patients with extended total occlusions of iliac and femoral arteries. All the patients had presented with critical ischemia of the lower extremities with the mean humeromalleolar index of 0.24+/-0.08. A technical success was achieved in 8 patients in whom the mean humeromalleolar index was 0.37+/-0.09. There were no procedure-associated complications.

Lambda and lambda production in central Pb-Pb collisions at 40, 80, and 158A GeV.

Production of Lambda and Antilambda hyperons was measured in central Pb-Pb collisions at 40, 80, and 158A GeV beam energy on a fixed target. Transverse mass spectra and rapidity distributions are given for all three energies. The Lambda/pi ratio at midrapidity and in full phase space shows a pronounced maximum between the highest BNL Alternating Gradient Synchrotron and 40A GeV CERN Super Proton Synchrotron energies, whereas the Lambda/pi ratio exhibits a monotonic increase.

[Original nitinol monowire stent for percutaneous iliac arterial reconstructions]. / Original'nyi stent iz mononiti nitinola v chreskozhnoi rekonstruktsii arterii podvzdoshnogo segmenta.

Nitinol monowire stents of original construction were implanted to 35 patients (aged from 36 to 84, mean 53.9) with atherosclerotic lesions of iliac arteries. Arterial stenosis ranged from 50% to 100% (mean 72.2%), ankle-brachial index (ABI) averaged 0.45+/-0.12. Initial success was achieved in 97.1% of procedures. Ultrasonography 3 days since the procedure showed the increase of ABI up to 0.78+/-0.16. Restenoses in the stented site was revealed during follow-up period (mean 24.3+/-18.3 months) in 3 patients (8.3%). In conclusion, new stent appeared to be effective tool for treatment of iliac atherosclerotic lesions. However long-term restenoses resulting from intimal hyperplasia can require repetitive revascularization.

Evidence for an exotic S= -2, Q= -2 baryon resonance in proton-proton collisions at the CERN SPS.

Results of resonance searches in the Xi(-)pi(-), Xi(-)pi(+), Xi;(+)pi(-), and Xi;(+)pi(+) invariant mass spectra in proton-proton collisions at sqrt[s]=17.2 GeV are presented. Evidence is shown for the existence of a narrow Xi(-)pi(-) baryon resonance with mass of 1.862+/-0.002 GeV/c(2) and width below the detector resolution of about 0.018 GeV/c(2). The significance is estimated to be above 4.2sigma. This state is a candidate for the hypothetical exotic Xi(--)(3/2) baryon with S=-2, I=3 / 2, and a quark content of (dsdsu). At the same mass, a peak is observed in the Xi(-)pi(+) spectrum which is a candidate for the Xi(0)(3/2) member of this isospin quartet with a quark content of (dsus[-]d). The corresponding antibaryon spectra also show enhancements at the same invariant mass.

[Metallic endoprostheses in the treatment of benign strictures of the biliary tract]. / Metallicheskie éndoprotezy v lechenii dobrokachestvennykh striktur biliarnogo trakta.

Nine original nitinol self-smoothing-out stents and 3 Gianturco stents were implanted to treat benign strictures of biliary ducts and biliodigestive anastomosis after ineffective repeated attempts to make balloon dilatation. There were no complications associated with the implantation procedure. The follow-up of patients varied from 3 to 26 months. After 4 months, reobturation was revealed at the site of repair in one case, which required implantation of an additional stent coated with polytetrafluoroethylene. The patency of the biliary tract was preserved in the remaining patients in the above period.
