Type I thyroplasty has become a primary surgical choise for voice restoration in patients with glottal incompetence due to vocal cord palsy. In this study 15 such cases of different etiologies were taken up for medializatioin laryngoplasty and their preoperative und post operative. voice assessment were done. We found that there was significant improvement in loudness: hoarseness and breathiness. Postoperative maximum phonation time also increased to normal limits. There were no major complications of the surgery. 相似文献

High-pressure phase stabilities up to 600 K and the related properties of Na2O2 under pressures up to 300 GPa were investigated using first-principles calculations and the quasi-harmonic approximation. Two high-pressure phases of Na2O2 that are thermodynamically and dynamically stable were predicted consisting of the Amm2 (distorted P2m) and the P21/c structures, which are stable at low temperature in the pressure range of 0–22 GPa and 22–28 GPa, respectively. However, the P2m and Pbam structures become the most stable instead of the Amm2 and P21/c structures at the elevated temperatures, respectively. Interestingly, the softening of some phonon modes and the decreasing of some elastic stiffnesses in the Amm2 structure were also predicted in the pressure ranges of 2–3 GPa and 9–10 GPa. This leads to the decreasing of phonon free energy and the increasing of the ELF value in the same pressure ranges. The HSE06 band gaps suggest that all phases are insulators, and they increase with increasing pressure. Our findings provide the P–T phase diagram of Na2O2, which may be useful for investigating the thermodynamic properties and experimental verification.High-pressure phase stabilities up to 600 K and the related properties of Na2O2 under pressures up to 300 GPa were investigated using first-principles calculations and the quasi-harmonic approximation. 相似文献

Objective
As invasive cardiovascular care has become increasingly complex, cardiac perforation leading to hemopericardium is a progressively prevalent complication. We sought to assess the frequency, etiology, and outcomes of hemorrhagic pericardial effusions managed through a nonsurgical echo-guided percutaneous strategy.Patients and Methods
Over a 10-year period (January 1, 2007, to December 31, 2016), 1097 unique patients required pericardiocentesis for clinically important pericardial effusions. Of these 411 had drainage of hemorrhagic effusions (defined as a pericardial hemoglobin level >50% of serum hemoglobin or frank blood in the setting of cardiac perforation). Clinical characteristics, echocardiographic data, details of the procedure, and outcomes were determined.Results
Median patient age was 67 years (interquartile range, 56-76 years), and 60% were men. The procedure was emergent in 83% and elective in 17%. The site of pericardiocentesis was determined by echo-guidance in all: 68% from the left para-apical region, 18% from the left or right parasternal areas, and 14% were subxyphoid. Half (n=215 [52%]) occurred after cardiac perforation with percutaneous interventional procedure (ablation, n=94; device lead implantation, n=65; percutaneous coronary intervention, n=22; other, n=34), whereas 30% followed cardiac or thoracic surgery. Pericardial fluid volume drained was 546±440 mL. In 94% of cases, echo-guided pericardiocentesis was the only treatment of the effusion needed, whereas definitive surgery was required in 25 (6%) cases for persistent bleeding or acute management of the underlying etiology. There was no procedural mortality. Late mortality was better for hemorrhagic effusions compared with a contemporary cohort with nonhemorrhagic effusions.Conclusion
Echocardiographic guidance allows rapid successful pericardiocentesis in the setting of hemopericardium related to microperforation with interventional procedures, malignancy, or pericarditis, with most not requiring surgical intervention. Surgery should remain the first-line approach for aortic dissection or myocardial rupture. 相似文献
