Several Procedures (several + procedure)
Selected AbstractsPapillary Muscle Approximation for Ischemic Mitral Valve RegurgitationJOURNAL OF CARDIAC SURGERY, Issue 6 2008Akhtar Rama M.D. Several procedures were described to restore a more normal alignment between the mitral annulus and the laterally displaced papillary muscles. We report a new approach to relocate the displaced papillary toward the mitral annulus and to reduce tethering. This procedure is believed to be technically easy and beneficial in terms of mitral repair. [source] Pitfalls of data mining: triclinic polymorph of 2,2-aziridinedicarboxamide revisitedACTA CRYSTALLOGRAPHICA SECTION B, Issue 1 2007Marcin Podsiad Several procedures have been employed for validating structural models refined on poor quality single-crystal diffraction data. Analysis of intra- and intermolecular distances in the structures of 2,2-aziridinedicarboxamide polymorphs proved to be a robust means, and a means independent of the chosen unit cell and symmetry, of detecting several incorrect atom-type assignments in the reported structure of the triclinic polymorph of 2,2-aziridinedicarboxamide [Brückner (1982). Acta Cryst. B38, 2405,2408]. The corrected model, refined in the space group , rules out the existence of any conformational polymorphism in this compound. Small differences in the powder-diffraction patterns calculated for the original and corrected structures of the triclinic polymorph illustrate the sensitivity of the above method for polymorph validation. [source] Phenol Chemical Matricectomy Is Less Painful, with Shorter Recovery Times but Higher Recurrence Rates, Than Surgical Matricectomy: A Patient's ViewDERMATOLOGIC SURGERY, Issue 8 2010JESSICA C. HASSEL DR MED BACKGROUND Ingrown toenails have a tendency for recurrence. Operative interventions can be successful, and several procedures are in use. OBJECTIVE Retrospective evaluation, to reveal differences in postoperative pain, time to recovery, and satisfaction with the cosmetic outcome in patients treated with a phenol (PCM) or surgical matricectomy (SM). MATERIALS & METHODS All matricectomy patients at the Dermatology Department of the Ludwigshafen City Hospital between 2004 and 2008 were interviewed over the telephone. Of 72 evaluable patients with a total of 112 ingrown nail sides, 33 were treated with PCM and 39 with SM. The patient group consisted of 40.3% women, the median age was 31. RESULTS Patients after PCM indicated two points less postoperative pain on an analogue scale from 0 to 10 (p<.001). In the PCM group, more patients recovered from the operation in less than 1 week (p=.007). Patient evaluation of cosmetic outcome was not different between the groups (p=.76), but recurrence rates were significantly higher in the PCM group (31.5%, vs 6.9% in the SM group, p=.006) CONCLUSION Both matricectomies have advantages and disadvantages. We should discuss these issues with our patients to help them decide on the kind of matricectomy. The authors have indicated no significant interest with commercial supporters. [source] Charge density profiling of circulating human low-density lipoprotein particles by capillary zone electrophoresisELECTROPHORESIS, Issue 17 2004Mine-Yine Liu Abstract Capillary zone electrophoresis (CZE) has been utilized to profile the low-density (LDL) particles in human blood serum in this study. A 5 mM sodium phosphate buffer, pH 7.40, was chosen as the most suitable CE buffer and an extensive ultrafiltration (UF) procedure was applied to purify the LDL sample. Two LDL particle species, LDL with lower mobility and LDL, with higher mobility were observed. The electropherograms were highly reproducible with good precision of effective mobilities, corrected peak areas (CPAs) and CPA ratio of LDL,/LDL. LDL particles shown on the electropherogram were also characterized by several procedures. The applications of Sigma HDL cholesterol reagent and CE on-line 2-propanol precipitation indicated that the two particle species shown in the electropherogram belong to LDL. The LDL particles were found to associate with the buoyant LDL fraction and the LDL, particles associate with the dense LDL fraction. This study utilizes CZE for the profiling of LDL isoforms and provides a new analytical method for the resolution of LDL subspecies. It demonstrates a high-mobility LDL particle which circulates in healthy subjects and diminishes in atherosclerotic patients. Diminution of the high-mobility LDL subspecies may be linked to minimal formation of arterial plaque in atherosclerotic patients. [source] Day surgery in Finland: a prospective cohort study of 14 day-surgery unitsACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 4 2009K. MATTILA Background: Day surgery is an established practice for elective operative care, and is considered safe and cost-effective in several procedures and for several patients. At present, day-surgery accounts for approximately 50% of elective surgery in Finland. The aim of this study was to prospectively describe the present situation at Finnish day-surgery units, focusing on the quality of care. Methods: Fourteen large- to medium-sized day surgery and short-stay units were recruited, and all patient cases performed during a 2-month study period were registered and analyzed. Quality of care was assessed by analyzing the rates and reasons for overnight admission, readmission, reoperation, and cancellations. Satisfaction of care was inquired from day- surgery patients during a 2-week period. Head anesthesiologists were interviewed about functional policies. Results: Of 7915 reported cases, 84% were day surgery. Typically, several specialties were represented at the units, with orthopedics accounting for nearly 30% of all day-surgery procedures. Patient selection criteria were in line with the present-day recommendations, although the proportion of older patients and the ASA physical status 3 patients were still relatively low. The rate of unplanned overnight admissions was 5.9%. Return hospital visits were reported in 3.7% and readmissions in 0.7% of patients 1,28 days post-operatively. Patient satisfaction was high. Conclusion: Along with the growing demand for day surgery, Finnish public hospitals have succeeded in providing good-quality care, and there still seems to be potential to increase the share of day surgery. Easily accessible benchmarking tools are needed for quality control and learning from peers. [source] A two-stage procedure for comparing hazard rate functionsJOURNAL OF THE ROYAL STATISTICAL SOCIETY: SERIES B (STATISTICAL METHODOLOGY), Issue 1 2008Peihua Qiu Summary., Comparison of two hazard rates is important in applications that are related to times to occurrence of a specific event. Conventional comparison procedures, such as the log-rank, Gehan,Wilcoxon and Peto,Peto tests, are powerful only when the two hazard rates do not cross each other. Because crossing hazard rates are common in practice, several procedures have been proposed in the literature for comparing such rates. However, most of these procedures consider only the alternative hypothesis with crossing hazard rates; many other realistic cases, including those when the two hazard rates run parallel to each other, are excluded from consideration. We propose a two-stage procedure that considers all possible alternatives, including ones with crossing or running parallel hazard rates. To define its significance level and p -value properly, a new procedure for handling the crossing hazard rates problem is suggested, which has the property that its test statistic is asymptotically independent of the test statistic of the log-rank test. We show that the two-stage procedure, with the log-rank test and the suggested procedure for handling the crossing hazard rates problem used in its two stages, performs well in applications in comparing two hazard rates. [source] Flexible fiberoptic bronchoscopy in children with heart diseases: A twelve years experiencePEDIATRIC PULMONOLOGY, Issue 4 2007Jaime Cerda MD Abstract In children, cardiac diseases and respiratory disorders are tightly linked entities whose evaluation should be performed integrally. Flexible fiberoptic bronchoscopy (FB) presents a diagnostic and therapeutic role by assessing the airway anatomically, dynamically, and through the performance of several procedures. The present study describes our experience on FB assessment in children with congenital and acquired cardiac diseases, providing a characterization of the principal demographic and clinical features. Records of 72 patients under 14 years (mean age 21 months) with heart diseases, corresponding to 104 FB performed between January 1993 and October 2004 were reviewed. The principal cardiac diseases were left-to-right shunt (51.9%), followed by right-to-left shunt (17.3%) and miscellaneous cardiopathies (8.7%). The main indications for FB assessment were study of atelectasis (35%), stridor (14%), and pneumonia (14%). Airway malacias, as a group, were the commonest finding, represented mainly by left main bronchus malacia (24%). The second most common finding was stenosis by extrinsic compression, and among these, 75% corresponded to left main bronchus compression. Sixteen different types of clinically meaningful utilities were obtained. No mortality was reported and in only one procedure was there a major complication, which was easily managed. We concluded that FB is an important and safe diagnostic,therapeutic tool in the health care of neonates, infants, and children with a variety of cardiac diseases.

Methods The current literature is reviewed and the experience of a tertiary referral centre is reported. Results CNV is a potentially sight-threatening sequela of uveitis. Several mistakes can be done during patients examination: CNV might not be recognized both at biomicroscopy and at fluorescein angiography (FA), for instance. Moreover, since some doctors are not aware of the importance of Indocyanine Green Angiography (ICGA), the choroidal involvement during inflammatory CNV might not be appreciated. These are just some examples of possible errors which can be done during the daily practice. The outcome of subfoveal CNV is poor if untreated: several procedures have been considered, even though there is lack of guidelines. The most important mistake can be represented by the lack of criticism on the treatment techniques: several methods have been proposed, albeit some of them should not be used on the basis of the treatment rationale and on the better knowledge of CNV pathophysiology. The presentation shows the most typical cases where the above mentioned mistakes have been done, suggesting some methods in order to avoid them. Conclusion CNV secondary to uveitis is a severe sequela, which can lead to significant visual impairment. Several mistakes can be done during both the diagnosis and the therapeutic procedures. Although no guideline is provided, the current medical literature can give the basis for a successful treatment strategy. [source] Progress in the appraisal and management of inflammatory CNVsACTA OPHTHALMOLOGICA, Issue 2009P NERI Purpose To review the current Literature and to describe the experience of a tertiary referral centre on the progress in the appraisal and the management of inflammatory choroidal neovascularization (CNV). Methods The current literature is reviewed and the experience of a tertiary referral centre is reported. Results CNV is a potentially severe sequela of posterior uveitis. The role of chronic inflammation has been described in experimental uveitis. For such reasons, even when biomicroscopy and fluorangiography (FA) cannot detect abnormalities, Indocyanine Green Angiography (ICGA) can show choridal anomalies. ICGA greatly improved the appraisal of the choroidal involvement, by providing reliable data for the diagnosis and for the management of inflammatory CNV. The new spectral domain optical coherence tomography (OCT) equipments can provide further informations that can be useful for a correct clinical assessment. The out-come of subfoveal CNV is poor if untreated: several procedures have been considered, even though there is lack of guidelines. Steroids, both local and systemic, are the first line therapy for non-infectious choroidal inflammation, although their long-term use can lead to unpleasant sequala, such as glaucoma and cataract. Immunesuppressive agents, lasers photocoagulation, photodynamic treatment, surgical removal and anti-Vascular Endothelial Growth Fact (VEGF) are other options. Conclusion CNV secondary to uveitis is a severe sequela leading to significant visual impairment. ICGA is mandatory in order to obtain relevant informations about the choroidal status. Several therapeutic options have been considered, but no guidelines are available at the moment. [source] Mindfulness: Method and ProcessCLINICAL PSYCHOLOGY: SCIENCE AND PRACTICE, Issue 2 2003Steven C. Hayes Understanding the processes and principles that underlie mindfulness is a needed step, because this method enters into the armamentarium of empirical clinical psychology. Mindfulness is closely related to several procedures, including acceptance, cognitive defusion, and exposure. Although each of these procedures seems to target different behavioral processes, they are all interrelated, because ultimately all of them target the domination of the literal and evaluative functions of human language and cognition. Because these methods are constructional, not eliminative, their rise may ultimately have a more profound impact on the field than is currently supposed. [source] | ||||||||||
