Purpose
To review the 64-slice CTA (computed tomography angiography) appearance of anatomical variations in branching pattern of the arcus aorta, and to determine their prevalence in 1001 cases.Materials and methods
1001 cases that underwent carotid CTA (performed by a 64-slice scanner) were included in the study.Results
Seven types of aortic arch were found. In 853 cases (853/1001, 85.2 %) classical branching pattern of arcus aorta (three branches; TB, LCC, LS) was observed. Variations were present in 147 cases (147/1001, 14.7 %). One case (1/1001, 0.1 %) had right aortic arch. The most frequent variation was origination of LCC from TB (arch with 2 branches, TB with LCC and LS) which was observed in 78 cases (78/1001, 7.8 %). Origination of LV directly from the aortic arch (four branches; TB, LCC, LV, LS or TB, LCC, LS, LV) was observed in 51 cases (51/1001, 5.1 %). In two cases (2/1001, 0.2 %) truncus bicaroticus (3 branches; RS, common trunk for carotids, LS) was present. In seven cases (7/1001, 0.7 %) aortic arch had four branches in the order of RCC, RS, LCC and LS. In one case (1/1001, 0.1 %) left truncus brachiocephalicus (three branches; RS, RCC, LTB) was present. Seven cases (7/1001, 0.7 %) had aberrant RS (RCC, LCC, LS, RS).Conclusion
Variations in branching pattern of arcus aorta are not rare and being aware of them before surgical and interventional procedures of this region is important. CTA can depict the anatomical features of the aortic arch and is valuable as a road map. 相似文献4.
Effect of chitosan on a periodontal pathogen Porphyromonas gingivalis 总被引:12,自引:0,他引:12

Local delivery systems of antimicrobial agents for treatment of the periodontal diseases received considerable attention during the past decade due to the disadvantages of the systemic administration. An ideal formulation should exhibit ease of delivery, a good retention at the application site, and a controlled release of the drug. The application of bioadhesive gels provides a long stay in the oral cavity, adequate drug penetration, high efficacy and acceptability. In dentistry and oral medicine, various applications of chitosan, which is a bioadhesive polymer have been proposed due to its favorable properties such as biocompatibility and biodegradability. The aim of this study was to determine the antimicrobial activity of chitosan formulations either in gel or film form against a periodontal pathogen, Porphyromonas gingivalis. The viscosity, bioadhesive properties and antimicrobial activity of chitosans at different molecular weight and deacetylation degree were evaluated in the absence or presence of chlorhexidine gluconate (Chx), incorporated into the formulations at 0.1 and 0.2% concentrations. The flow property of the gels were found to be suitable for topical application on the oral mucosa and to syringe into the periodontal pocket. Bioadhesion of the gels and films examined ex-vivo using fresh porcine buccal mucosa showed that both the film and gel formulations exert bioadhesive properties and was not affected by incorporation of Chx. Chitosan is shown to have an antimicrobial activity against P. gingivalis and this was higher with high molecular weight chitosan. The combination of chitosan with Chx showed a higher activity when compared to that of Chx alone, which would provide Chx application at lower concentrations thus avoiding its unwanted side effects. Chitosan films and gels seem to be promising delivery systems for local therapy of periodontal diseases with its bioadhesive property and antimicrobial activity. 相似文献

AbstractThe aim of this study was to investigate the role of PON1Q192R and L55M single nucleotide polymorphisms(SNPs) and its association with the maternal levels of lipid parameters in gestational diabetes mellitus(GDM) and preeclampsia(PE). Ninety-nine pregnant with GDM, 97 pregnant with PE and 98 healthy pregnant were included in the study. No statistically significant difference was observed in the alleles or in the genotypes frequencies of SNPs between groups. In GDM patients, total cholesterol was higher in MM genotype of L55M gene (p?<?.05); Lp(a) were lower in LM genotype of the gene compared to their respective control (p?<?.05). In PE, HDL-C levels were higher in LM genotype (p?<?.05); LDL-C levels were lower in MM genotype of the gene compared to their respective control (p?<?.05). In PE patients, malondialdehyde(MDA) were higher in QQ genotype compared to their respective control (p?<?.05). Triglyceride levels were higher in PE patients with QR genotype compared with GDM patients with QR genotype (p?<?.05). Our results indicated that lipid profiles, Lp(a) and MDA levels showed significant differences in GDM and PE pregnants. These findings support the importance of the lipid profile, oxidized lipid and Lp(a) in different genotypes of L55M and Q192R in Turkish pregnant women with PE/GDM suggesting their roles in etiopathogenesis in these pregnancy-related disorders. 相似文献

Background:
In patients with chronic hepatitis C, triple drug regimens containing a protease inhibitor, peginterferon and ribavirin were found to significantly increase sustained virologic response rates compared to dual drug regimen containing pegylated interferon and ribavirin, especially in genotype 1.Objectives:
In Turkey, telaprevir has been used since March 2013. We aimed to evaluate results of patients with chronic hepatitis C treated with telaprevir, peginterferon and ribavirin.Patients and Methods:
We evaluated 28 patients with genotype 1 chronic hepatitis C infection treated with triple drug regimen containing telaprevir, in three medical centers in Turkey, retrospectively. Demographic data of patients, treatment indications, adverse events and outcomes were recorded.Results:
Of 28 patients intended to treat, 25 (89.2%) patients completed the treatment. Overall, 21 (82.1%) patients had relapse and five patients were non-responder. Regarding the treatment outcomes of Telaprevir based regimen, 20/26 patients achieved sustained virological response. Pruritus, rash, dysgeusia, anorectal discomfort and anemia were main adverse effects. Blood transfusion and ribavirin dose reduction required for 7 and 11 patients, respectively. Due to several adverse effects, 10 patients were hospitalized.Conclusions:
Although more frequent and severe adverse effects, telaprevir has been promising for patients with treatment-experienced hepatitis C. 相似文献9.

To report a case of HIV infection presenting with thrombotic thrombocytopenic purpura (TTP) and brucellosis that responded
well to plasmapheresis and anti-infective therapy. A 64-year-old woman with moderate confusion, fever and pancytopenia was
admitted. HIV infection history was taken from her family and she was not receiving antiretroviral therapy last one year.
She had generalized purpuric skin lesions. Wright tube agglutination test was found positive with a 1:160 dilution and the
patient was diagnosed as brucellosis. Detailed literature search showed brucellosis as a possible cause of TTP. Patient was
treated by plasma exchange/fresh frozen plasma and antimicrobials and the response was excellent. Although brucellosis seems
to explain the clinical picture of this patient, it is revealed that broad differential diagnosis is needed to reach uncommon
diagnosis like TTP particularly in HIV infected patients. 相似文献
