    Introduction: Les diplegies laryngees en fermeture sont rares et mal tolerees par les patients. Leur prise en charge therapeutique a connu de nombreuses avancees au cours des dernieres annees. Le but de ce travail est dfetudier la place du laser dans leur prise en charge.Malades et methodes : Notre etude est retrospective a propos de six patients porteurs de diplegie laryngee en fermeture. Lfage moyen etait de 46 ans (16 et 70 ans). Lfetiologie etait une intubation prolongee ou traumatique dans 3 cas, post thyroidectomie totale dans deux autres cas et idiopathique dans 1 cas. Le traitement a consiste en une tracheotomie en urgence dans 5 cas. Tous les patients ont beneficie dans un secondtemps dfun traitement au laser apres 9 mois de surveillance.Resultats : La cordectomie posterieure a ete realisee en premier temps dans 4 cas. Elle etait bilaterale en deux temps dans 2 cas et unilaterale dans 2 cas. Une aryteno.dectomie initiale a ete realisee pour les deux autres patients. Une revision chirurgicale a consiste en une arytenoidectomie dans 2 cas et une cordotomie partielle posterieure controlaterale dans un cas. La decanulation etait bien toleree pour 4 patients. Un seul malade a garde une gene respiratoire sans veritabledyspnee avec une canule parlante fermee et la decanulation a ete refusee. Une voix satisfaisante a ete obtenue pour tous les malades. Des fausses route transitoires ont ete note dans 2 cas.Discussion : Actuellement, le traitement endoscopique au laser constitue le traitement de choix dans la diplegie laryngee et doit etre propose en premiere intension. Deux techniques principales sont decrites :  lfaryteno.dectomie au laser type Ossof et la cordectomie posterieure transverse de kashima. plusieurs series ont defendu chacune des deux techniques. Notre serie a montre que les deux techniques peuvent etre associees pour donner de meilleurs resultats.Mots cles : diplegie laryngee, Laser, aryteno.dectomie, cordectomie posterieure

    Relationship between biomarkers of muscle damage and redox status in response to a weightlifting training session: effect of time-of-day

    The aims of the present study were to: (1) investigate the effect of a weightlifting training session and time-of-day (TOD) upon biological parameters (i.e., oral temperature, hematological, C-reactive protein (CRP), and oxidative stress) and (2) assess their possible link with muscle damage responses. Nine weightlifters (21 ± 0.5 years) performed, in a randomized order, three Olympic-Weightlifting sessions (i.e., at 08:00, 14:00, and 18:00). Blood samples were collected at rest, 3 min and 48 h after each training session. Between pre- and post-training session, ANOVA showed significant increases in oxidative stress markers at the three TODs (p < 0.01) and significant increases for creatine kinase (CK) and lactate dehydrogenase (LDH) only at 08:00 and 18:00 (p < 0.05). At rest, the results showed a significant diurnal variation for the majority of the selected parameters except for malondialdehyde (MDA), total bilirubin, and CRP with higher values observed at 18:00 (p < 0.05). After the training session, given the higher rate of increase during the morning session, these diurnal variations persisted for temperature and WBC (p < 0.01) and were suppressed for CK, LDH, uric acid (UA), catalase, and glutathione peroxidase. The main significant correlations (p < 0.001) were observed between: (1) CK and MDA (r = 0.6) and CK and UA (r = 0.66 and r = 0.82) during the morning and evening training sessions; (2) CK and CRP only during the morning session (r = 0.5); and (3) CRP and WBC during the three training sessions (r = 0.8). In conclusion, the present findings: (1) confirm that the muscle damage responses could be induced by a high level of oxidative stress and (2) suggest to avoid scheduling training sessions in the morning given the higher muscle damage, inflammatory, and oxidative responses at this TOD

    Restriction-based Fragmentation of Business Processes over the Cloud

    Get PDF
    Despite the elasticity and pay-per-use benefits of cloud computing (aka fifth utility computing), organizations adopting clouds could be locked-into single cloud providers, which is not always a “pleasant” experience when these providers stop operations. This is a serious concern for those organizations that who would like to deploy (core) business processes on the cloud along with tapping into these 2 benefits. To address the lock-into concern, this paper proposes an approach for decomposing business processes into fragments that would run over multiple clouds and hence, multiple providers. To develop fragments, the approach considers both restrictions over ownersof business processes and potential competition among cloud providers.Onthe one hand, restrictions apply to each task in a business process and are specialized into budget to allocate, deadline to meet, and exclusivity to request. On the other hand, competition leads cloud providers to offer flexible pricing policies that would cater to the needs and requirements of each process owner. A policy handles certain clouds’ properties referred to as limitedness, non-renewability, and nonshareability that impact the availability of cloud resources and hence, the whole fragmentation. For instance, a non- shareable resource could delay other processes, should the current process do not release this resource on time. During fragmentation interactions between owners of processes and providers of clouds happen according to 2 strategies referred to as global and partial. The former collects offers about cloud resources from all providers, while the latter collects such details from particular providers. To evaluate these strategies’ pros and cons, a system implementing them as well as demonstrating the technical feasibility of the fragmentation approach using credit-application case study, is also presented in the paper. The system extends BPMN2- modeler Eclipse plugin and supports interactions of processes’ owners with clouds’ providers that result to identifying the necessary fragments with focus on cost optimization

    Renal and neurological side effects of colistin in critically ill patients

    Get PDF
    Colistin is a complex polypeptide antibiotic composed mainly of colistin A and B. It was abandoned from clinical use in the 1970s because of significant renal and, to a lesser extent, neurological toxicity. Actually, colistin is increasingly put forward as salvage or even first-line treatment for severe multidrug-resistant, Gram-negative bacterial infections, particularly in the intensive care setting. We reviewed the most recent literature on colistin treatment, focusing on efficacy and toxicity issues. The method used for literature search was based on a PubMed retrieval using very precise criteria

    <p>Abstract</p> <p>Background</p> <p>Knowledge of the etiology of pyogenic liver and pancreatic abscesses is an important factor in determining the success of combined surgical and antibiotic treatment. Literature shows geographical variations in the prevalence and distribution of causative organisms, and the spread of <it>Klebsiella pneumoniae </it>carbapenemase-producing bacteria is an emerging cause of abdominal infections.</p> <p>Case presentation</p> <p>We herein describe two cases of intra-abdominal abscesses due to monomicrobial infection by <it>Klebsiella pneumoniae </it>Sequence Type 258 producing <it>K. pneumoniae </it>carbapenemase 3 (KPC-Kp). In case 1, a 50-year-old HIV-negative Italian woman with chronic pancreatitis showed infection of a pancreatic pseudocystic lesion caused by KPC-Kp. In case 2, a 64-year-old HIV- negative Italian woman with pancreatic neoplasm and liver metastases developed a liver abscess due to KPC after surgery. Both women were admitted to our hospital but to different surgical units. The clonal relationship between the two isolates was investigated by pulsed-field gel electrophoresis (PFGE). In case 2, the patient was already colonized at admission and inter-hospital transmission of the pathogen was presumed. A long-term combination regimen of colistin with tigecycline and percutaneous drainage resulted in full recovery and clearance of the multidrug-resistant (MDR) pathogen.</p> <p>Conclusions</p> <p>Timely microbiological diagnosis, the combined use of new and old antibiotics and radiological intervention appeared to be valuable in managing these serious conditions. The emergence and dissemination of MDR organisms is posing an increasing challenge for physicians to develop new therapeutic strategies and control and prevention frameworks.</p

    Estrogen Receptor-Beta Gene Polymorphism in women with Breast Cancer at the Imam Khomeini Hospital Complex, Iran

    ER-alpha and ER-beta genes have been proven to play a significant role in breast cancer. Epidemiologic studies have revealed that age-incidence patterns of breast cancer in Middle East differ from those in the Western countries. Two selected coding regions in the ER-β gene (exons 3 and 7) were scanned in Iranian women with breast cancer (150) and in healthy individuals (147). PCR single-strand conformation polymorphism was performed. A site of silent single nucleotide polymorphism was found only on exon 7. The SNP was found only in breast cancer patients (5.7%) (χ2 = 17.122, P = 0.01). Codon 392 (C1176G) of allele 1 was found to have direct association with the occurrence of lymph node metastasis. Our data suggest that ER-β polymorphism in exon 7 codon 392 (C1176G) is correlated with various aspects of breast cancer and lymph node metastasis in our group of patients

    <p>Abstract</p> <p>Background</p> <p>The immune responses to bacterial products through the pattern recognition receptor (PRR) play a pivotal role in pathogenesis of Crohn's disease. A recent study described an association between CD and some gene coding for bacterial receptor like NOD2/CARD15 gene and TLR4. In this study, we sought to determine whether TLR4 gene was associated with Crohn's disease (CD) among the Tunisian population and its correlation with clinical manifestation of the disease.</p> <p>Methods</p> <p>90 patients with CD and 80 healthy individuals are genotyped for the <it>Asp299Gly </it>and <it>Thr399Ile </it>polymorphisms by restriction fragment length polymorphism analysis.</p> <p>Results</p> <p>The allele and genotype frequency of the TLR4 polymorphisms did not differ between patients and controls. The genotype-phenotype correlation permitted to show that the <it>Thr399Ile </it>polymorphism was associated with early onset disease.</p> <p>Conclusion</p> <p>this study reported the absence of association between CD and TLR4 gene in the Tunisian population, but this gene could play a role in clinical expression of the disease.</p

    First Molecular Epidemiological Study of Cutaneous Leishmaniasis in Libya

    Cutaneous leishmaniasis (CL) is caused by protozoan parasites of the genus Leishmania. The disease is characterized by the formation of chronic skin lesions followed by permanent scars and deformation of the infected area. It is distributed in many tropical and subtropical countries with more than 2 million cases every year. During the past few years CL has emerged as a major public health problem in Libya. So far, diagnosis was based on clinical symptoms and microscopic observation of parasites. Disease outbreaks were not investigated and the causative leishmanial species of CL were not identified so far. Our study indicates the presence of two coexisting species: Leishmania major and Leishmania tropica. These results are crucial in order to provide accurate treatment, precise prognosis and appropriate public health control measures. The recent armed conflict in Libya that ended with the Gadhafi regime collapse on October 2011 has affected all aspects of the life in the country. In this study we discussed multiple risk factors that could be associated with this conflict and present major challenges that should be considered by local and national health authorities for evaluating the CL burden and highlighting priority actions for disease control
