Transcatheter Closure of a Residual Patent Ductus Arteriosus After Surgical Ligation in Children
Osman Baspinar,Metin Kilinc,Mehmet Kervancioglu,Ahmet Irdem 대한심장학회 2011 Korean Circulation Journal Vol.41 No.11
Background and Objectives: To assess the safety and efficacy of transcatheter closure of residual ductal flow after initial surgical ligation of the arterial duct. Subjects and Methods: Between June 2005 and December 2009, transcatheter occlusion of residual postsurgical ductus arteriosus was performed in six children. Results: The mean patient age was 10±5.5 years; mean post-procedural time since the initial surgical closure was 6.3±4.5 years. The mean diameter of the patent ductus arteriosus on angiography was 1.3±0.5 mm (range, 0.8 to 2.4 mm). Three different types of coils were used successfully without any complications. Conclusion: Transcatheter occlusion of residual postsurgical arterial duct is a safe and successful procedure. However, attention should be paid due to the distorting shape of the arterial duct.
Utilization Potential of Fly Ash together with Silica Fume in Autoclaved Aerated Concrete Production
M. Serhat Baspinar,Ismail Demir,Erhan Kahraman,Gokhan Gorhan 대한토목학회 2014 KSCE JOURNAL OF CIVIL ENGINEERING Vol.18 No.1
The increase in the number of thermal power plants has led to the production of an increasing amount of fly ash that causes high environmental impact in Turkey. Many researchers around the world are looking at methods of gainful utilization and disposal of fly ash. However, the construction materials industry is the most suitable way to mass consumption of the fly ash waste. In this study, the utilization potential of fly ash and silica fume in Autoclaved Aerated Concrete (AAC) production were investigated. Optimum fly ash/cement ratio was determined, and this composition was improved by the silica fume addition. Strength-Microstructure relations of the products were investigated. Crystalline C-S-H phases of Tobermorite and Xonotlite were developed after autoclaving at 4 bar. Silica fume addition was found to be useful for the prevention of the ettringite phase in the product. Silica fume addition improved the hydrothermal conditions during the autoclaving of the mixtures.

Background: To determine the level of knowledge on human papillomavirus (HPV) infection and vaccination, and the attitude towards HPV vaccination in pediatricians, obstetricians and gynecologists (OBG). Materials and Methods: Participants were administered a 40-question survey, investigating the demographic properties, the knowledge on the HPV infection-vaccination and attitudes towards vaccination. Results: The study enrolled a total of 228 participants (131 pediatricians and 97 OBGs). At a rate of 99.6%, the participants agreed with the fact that the HPV infection was the most common sexually transmitted disease and 33.8% of the participants had the opinion that the HPV vaccination should be administered only in women. The lowest level of HPV vaccine recommendation was among the pediatrics specialists (59.4%, p=0.012). When asked whether they would have their daughters receive HPV vaccination, 79.5% of the participants answered favorably; this rate was 36.7% for the sons. At a rate of 59.5% of the participants thought that the HPV vaccine needed to be included in the national vaccine schedule. Most of the participants (91.6%) had the idea that reduction of the vaccine costs would increase the vaccination frequency. Conclusions: We observed that the consideration of the costs and the prejudices relating to the inefficacy of vaccination as well as the inadequate level of knowledge were involved in the physicians' resistance to HPV vaccination. We believe that the healthcare professionals should be informed adequately to overcome false beliefs, thereby ensuring success of the HPV vaccine upon inclusion in the national vaccine schedule in the future.

Purpose: To investigate clinicopathological features in patients with recurrent colorectal cancer within 1 year and more than 1 year after curative resection. Materials and Methods: We retrospectively evaluated 103 patients with disease recurrence before versus after 1 year of resection. Thirty-two patients (31%) were diagnosed with recurrence less than 1 year after curative resection for colorectal cancer (early recurrence) and 71 (69%) after more than 1 year (non-early recurrence). Results: The early recurrence group displayed a significantly lower overall survival rate for both colon cancer (p=0, 01) and rectal cancer (p<0.001). Inadequate lymph node dissection was a significant predictor for early relapse. There were no statistically significant differences in clinicopathological variables such as age, sex, primary tumor localization, stage, depth of invasion, lymphovascular invasion and perineural invasion between the early and non-early recurrence groups. However, a K-ras mutation subgroup was significantly associated with early recurrence (p<0.001). Conclusions: Poor survival is associated with early recurrence for patients undergoing resection for non-metastatic colorectal cancer, as well as K-ras mutation.
