Cardiomyopathy refers to a set of diseases that are characterized by myocardial dysfunction. Classically, two-dimensional echocardiography has been used in the diagnosis of these disorders and to help guide their management. Three-dimensional transthoracic echocardiography is now increasingly being used in the diagnosis, management, and prognostication of intrinsic cardiomyopathies. In this article, we summarize the available data on the use of three-dimensional transthoracic echocardiography in various forms of intrinsic cardiomyopathy as well as some of its advantages over traditional two-dimensional transthoracic echocardiography.

Clinical,Microbial, and Immune Responses Observed in Patients With Diabetes After Treatment for Gingivitis: A Three‐Month Randomized Clinical Trial 下载免费PDF全文
Suzane A. Raslan Jose R. Cortelli Fernando O. Costa Davi R. Aquino Gilson C.N. Franco Luis O.M. Cota Antonio Gargioni‐Filho Sheila C. Cortelli 《Journal of periodontology》2015,86(4):516-526
Background: Although patients with diabetes are frequently affected by periodontitis, only a few investigations have focused on gingivitis in this at‐risk population. This randomized placebo‐controlled clinical trial compared the response to a gingivitis treatment protocol that combined mechanical procedures and daily use of an essential oil (EO) mouthrinse between patients with and without diabetes. Methods: The whole‐mouth periodontal probing depth (PD), gingival index (GI), and plaque index (PI) were monitored in gingivitis cases among systemically healthy patients (n = 60) or those with diabetes (n = 60) at baseline and 3 months after treatment. Levels of Porphyromonas gingivalis, Tannerella forsythia, Aggregatibacter actinomycetemcomitans, and total bacterial load were determined by a real‐time polymerase chain reaction in intrasulci plaque samples. The volume of gingival crevicular fluid (GCF) was quantified, and interleukin‐1β (IL‐1β) levels were determined in GCF samples. After a full‐mouth ultrasonic debridement, patients were randomly assigned to an EO or a placebo rinse for 90 days (40 mL/day). The data were analyzed through repeated‐measures analysis of variance and multiple comparisons Tukey tests (P <0.05). Results: GI was more severe in the diabetes group. Diabetes impaired GI and reduced GCF volume. PD, bacterial levels, and IL‐1β improved similarly in both systemic conditions. The adjunctive use of EO provided greater reductions of PI, GI, total bacterial load, T. forsythia, A. actinomycetemcomitans, and GCF volume. Conclusions: Response to gingivitis treatment in patients with diabetes can slightly differ from that in patients without diabetes. Daily use of an EO mouthrinse after ultrasonic debridement benefited patients with and without diabetes. 相似文献

Background: Expression patterns of human β‐defensin‐2 (HBD‐2) mRNA or HBD‐2 protein concentration and periodontal diseases have been a focus of scientific research. This study compares the salivary levels of HBD‐2 protein concentration of healthy patients and patients with gingivitis and chronic periodontitis (CP) and correlates these levels with the presence of periodontopathogens. Methods: A total of 89 patients were enrolled in this study: 31 periodontally healthy, 27 with gingivitis, and 31 with CP. Plaque and gingival indices, probing depth, and clinical attachment level were measured. The presence of Campylobacter rectus, Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Tannerella forsythia, Treponema denticola, and Prevotella intermedia was evaluated qualitatively by conventional polymerase chain reaction. HBD‐2 quantification in saliva was performed using an immune enzymatic assay. Frequency of periodontopathogens and HBD‐2 protein concentration was assessed. Association between HBD‐2 protein concentration (≥100 pg/mL) and the simultaneous presence of one to two, three to four, or five to six periodontopathogens was tested. Results: Although periodontally healthy individuals and patients with gingivitis showed similar HBD‐2 levels, the CP group displayed an increased level of HBD‐2. P. gingivalis, P. intermedia, T. forsythia, and T. denticola were more prevalent in CP; however, their mere presence was not related to the increased levels of HBD‐2 (Pearson correlation and multinomial logistic regression model). Conclusions: Salivary HBD‐2 protein concentration was higher in patients with CP compared with healthy individuals or patients with gingivitis. These different protein concentrations were not related to the frequency of periodontopathogens. Clinical inflammatory profile had a higher impact on salivary HBD‐2 levels than bacteria. 相似文献

Electroneurography (ENoG) is currently the most sophisticated and objective test available for assessing nerve degeneration in patients suffering from facial nerve paralysis. However, the test requires considerable experience before error due to intertest variability can be brought within reasonable limits. In a statistical study on normal participants, the error associated with two conventional recording techniques—optimized lead placement (OLP) and standardized lead placement (SLP)—was determined to be 17.8% and 20.7%, respectively. A significant increase in error was observed with the OLP approach (22.9%) if responses could not be monitored oscilloscopically, a common situation in patients with severe degeneration. In a final study, however, a previously unreported factor was found to significantly reduce test error: recording electrode size. In particular, unconventionally small recording electrodes (3 to 7 mm) produced as much as 4% less error when administering the technique. 相似文献

Cyanoacrylate derivatives have been used as surgical adhesives for many years. Shorter-chain derivatives (methyl- and ethyl-cyanoacrylate) have proved to be histotoxic. Longer-chain derivatives (butyl- and isobutyl-cyanoacrylate) are much less histotoxic. Many surgeons continue to use ethyl-2-cyanoacrylate (Krazy Glue) despite the availability of a less toxic derivative, butyl-2-cyanoacrylate (Histoacryl). In this study, the histotoxicity and bone graft-cartilage binding ability of Krazy Glue and Histoacryl were compared. Bone grafts harvested from the anterior wall of the maxillary sinus were placed in a subcutaneous pocket and glued to auricular cartilage in the rabbit. Krazy Glue and Histoacryl were used in opposite ears, harvesting specimens at 1, 2, 4, 12, 24, and 48 weeks. The Krazy Glue-treated ears developed seromas with histologic evidence of acute inflammation, tissue necrosis, and chronic foreign body giant cell reaction. The Histoacryl-treated ears showed mild acute inflammation and mild foreign body giant cell reaction. The Krazy Glue was completely degraded within 12 months, while some Histoacryl was still present at 1 year. Histoacryl had minimal histotoxic effect and good bone graft-cartilage binding ability, whereas Krazy Glue demonstrated severe histotoxicity. 相似文献
