    Aim of investigation. Clinical and endoscopical investigation of the large intestine in patients of senile age with chronic constipation and estimation of rational treatment.Material and methods. Overall 287 senile patients with chronic constipation were included in original study (mean age 79Β±2,7). Complex investigation included videocolonoscopy and choosing of drug for rational therapy.Results. It was revealed, that digestive and endocrine diseases are most common in this group of patients. At endoscopic investigation diverticulosis and polyposis coli were the most frequent findings. All patients have tolerated investigation well, no complications have developed. Restoration of regular defecations on a background of lactulose (Duphalac) intake was accompanied by disappearance of feeling of incomplete defecation and necessity of intensive straining effort at defecation.Conclusions. In senile patients chronic constipation is widespread functional disorder, which does not exclude, however, endoscopic control. The age of the patient is not a limiting factor for colonoscopy. Lactulose (Duphalac) is an optimal pharmaceutical with high efficacy

    The aim of the work is to study the indicators of local and systemic immunity in frequently ill children with community-acquired therapy to improve the methods of therapy. 55 children with community-acquired pneumonia and recurrent respiratory diseases (8 or more per year) aged from 3 to 7 years were examined. In the main group (n = 30), on the background of standard therapy, the children received the immunomodulator azoximerΠ΅ bromide. In the comparison group (n = 25), the children received conventional therapy. Assessment of the state of systemic and mucosal immunity was carried out in dynamics before treatment and after therapy. It was shown that the inclusion of azoxymere bromide leads to an optimal correction of cellular immunity, phagocytic activity of neutrophils, as well as systemic and local cytokine profile. Clinical efficacy is manifested by a reduction in the duration of the febrile period, more rapid relief of intoxication syndromes, respiratory and local pulmonary changes.ЦСль Ρ€Π°Π±ΠΎΡ‚Ρ‹ β€” ΠΈΠ·ΡƒΡ‡Π΅Π½ΠΈΠ΅ ΠΏΠΎΠΊΠ°Π·Π°Ρ‚Π΅Π»Π΅ΠΉ мСстного ΠΈ систСмного ΠΈΠΌΠΌΡƒΠ½ΠΈΡ‚Π΅Ρ‚Π° Ρƒ часто Π±ΠΎΠ»Π΅ΡŽΡ‰ΠΈΡ… Π΄Π΅Ρ‚Π΅ΠΉ с Π²Π½Π΅Π±ΠΎΠ»ΡŒΠ½ΠΈΡ‡Π½ΠΎΠΉ ΠΏΠ½Π΅Π²ΠΌΠΎΠ½ΠΈΠ΅ΠΉ для ΡΠΎΠ²Π΅Ρ€ΡˆΠ΅Π½ΡΡ‚Π²ΠΎΠ²Π°Π½ΠΈΡ ΠΌΠ΅Ρ‚ΠΎΠ΄ΠΎΠ² Ρ‚Π΅Ρ€Π°ΠΏΠΈΠΈ.

    First CNGS events detected by LVD

    Get PDF
    The CERN Neutrino to Gran Sasso (CNGS) project aims to produce a high energy, wide band Ξ½ΞΌ\nu_{\mu} beam at CERN and send it toward the INFN Gran Sasso National Laboratory (LNGS), 732 km away. Its main goal is the observation of the Ξ½Ο„\nu_{\tau} appearance, through neutrino flavour oscillation. The beam started its operation in August 2006 for about 12 days: a total amount of 7.6Β 10177.6~10^{17} protons were delivered to the target. The LVD detector, installed in hall A of the LNGS and mainly dedicated to the study of supernova neutrinos, was fully operating during the whole CNGS running time. A total number of 569 events were detected in coincidence with the beam spill time. This is in good agreement with the expected number of events from Montecarlo simulations.Comment: Accepted for publication by the European Physical Journal C ; 7 pages, 11 figure

    On-line recognition of supernova neutrino bursts in the LVD detector

    Full text link
    In this paper we show the capabilities of the Large Volume Detector (INFN Gran Sasso National Laboratory) to identify a neutrino burst associated to a supernova explosion, in the absence of an "external trigger", e.g., an optical observation. We describe how the detector trigger and event selection have been optimized for this purpose, and we detail the algorithm used for the on-line burst recognition. The on-line sensitivity of the detector is defined and discussed in terms of supernova distance and electron anti-neutrino intensity at the source.Comment: Accepted for pubblication on Astroparticle Physics. 13 pages, 10 figure

    The treatment of acute corneal hydrops by subtotal penetrating keratoplasty. Clinical case

    Get PDF
    Clinical case of acute hydrops treatment using subtotal penetrating keratoplasty (PK) is presented. The diagnosis ofΒ acute hydrops was based on clinical and functional evaluations including optical coherent tomography (OCT). A part ofΒ diseased cornea was removed and examined under a light microscope. These studies revealed morphological changes in almost all corneal layers. OCT and histology demonstrated that PK was indicated to this patient. Recent literature data on the epidemiology and pathogenesis of acute hydrops are presented. This rare disease results from tears in the Descemet’s membrane that allow aqueous humor to enter the stroma. Current treatment is aimed to suppress corneal inflammation, restore endothelium and Descemet’s membrane integrity and drain stromal cysts to optimize cornea healing. In this case, subtotal PK was performed due to the significant corneal thinning and a high risk of its melting. Β«Material for corneal graftΒ» (iLab, Moscow, Russia) was used as a donor material

    The results of an epidemiological study of risk factors of HIV infection among women, who inject drugs, are presented in this paper. Incidence of HIV among women during the period from 2005 to 2013 had a significant increasing trend from 2,1 to 63,3 per 100000 women. The predominance of parenteral transmission of HIV, as well as a significant prevalence of substance abuse disorders among women, determined a significant risk of morbidity for women with HIV infection (6,3 per 10,000 women). We included 115 women, taking injection drugs, in our study. Most of the women noted patterns of high risk HIV infection behavior, as well as the lack of knowledge about HIV prevention. 45% of women had been using drugs for 6-11 years, most of them have started using drugs at the age of 16-19 years, 40% of participants have used more than one type of drug, used common needles, syringes, together with other persons, including those with HIV infection. 23,8% of the women mentioned having unprotected sex, including sex with casual sex partners

    Searching for New Physics Through AMO Precision Measurements

    Full text link
    We briefly review recent experiments in atomic, molecular, and optical physics using precision measurements to search for physics beyond the Standard Model. We consider three main categories of experiments: searches for changes in fundamental constants, measurements of the anomalous magnetic moment of the electron, and searches for an electric dipole moment of the electron.Comment: Prepared for Comments on AMO Physics at Physica Script
