PURPOSE: We compared the safety and efficacy of ureteroscopy with intravenous propofol anesthesia with those with spinal anesthesia for the treatment of lower ureteral calculi. MATERIALS AND METHODS: Ureteroscopy with intravenous propofol anesthesia was performed in 38 patients with ureteral caluli, and spinal anesthesia was performed in 41. Ureteroscopy was performed with a 9.5Fr rigid ureteroscope. RESULTS: The overall success rate of stone removal was 99% (100% in IV propofol anesthesia cases and 98% in spinal anesthesia cases). Hospital stay times were significantly shorter for patients given propofol: 1.5 vs 3 days, respectively(p<0.05). CONCLUSIONS: Stone removal under intravenous propofol anesthesia does not increase the risk of complication or compromise the results of treatment and hospital stay times.

Clavicle fractures are frequently seen with the recent increase in traffic and industrial accidents. Recently, in adults, open reduction and internal fixation techniques are commonly performed for the patient to return earlier to their jobs. But internsl fixation technique for clavicle fractures has been a subject of controversy. We operated on 78 cases of fractures of the middle third of clavicle by the technique of intramedullary threaded Steinmann pin fixation from March 1985 to Nov. 1988. The following results were obtained. 1. The funtional results were excellent; 32 cases(41%), good; 41 cases(53%), fair ; 5 cases (6%). 2. The complications include motion limitation ; 5 cases(6%), pin tract infection ; 5 cases (6%), delayed union ; 1 case(1%) 3. The advantages of intramedullary threaded Steinmann pim fixation are as follows. 1) Early active range of motion is possible. 2) The operation procedure is simple to perform. 3) Removal of the pin is easy without anesthesia. Therefore, intramedullary threaded Steinmann pin fixation is thought to be a good operative technique for the clavicle fracture.

OBJECTIVE:To evaluate the biodurability of the covering material in retrievable metallic stents covered with polycarbonate polyurethane. MATERIALS AND METHODS: Using a peristaltic pump at a constant rate of 1ml/min, bile was recirculated from a reservoir through a long tube containing four stents. Each of these was removed from the system every two weeks and a radial tensile strength test and scanning electron microscopy (SEM) were performed. Each stent, removed at 2, 4, 6 and 8 weeks, was compared with a control stent not exposed to bile juice. RESULTS: Gross examination showed that stents were intact at 2 weeks, but at 4, 6 and 8 weeks cracks were observed. The size of these increased gradually in accordance with the duration of exposure, and at 8 weeks several large holes in the polyurethane membrane were evident. With regard to radial tensile strength, extension and peak load at break were 84.47% and 10.030 N/mm, 54.90% and 6.769 N/mm, 16.55% and 2.452 N/mm, 11.21% and 1.373 N/mm at 0, 2, 4 and 6 weeks, respectively. Scanning electron microscopy at 2 weeks revealed intermittent pitting and cracking, and examination at 4, 6 and 8 weeks showed that the size of these defects was gradually increasing. CONCLUSION: When the polyurethane membrane was exposed to bile, biodegradation was first observed at week two and increased gradually according to the duration of exposure.

PURPOSE: We studied to determine whether the degenerative spondylolisthesis has rotary deformity in addition to forward displacement. MATERIALS AND METHODS: We have made an analysis of difference of rotary deformity between the 31 study groups of symptomatic degenerative spondylolisthesis and 31 control groups without any symptom,statistically. We also reviewed CT findings in 15 study groups. RESULTS: The mean rotary deformity in study groups was 6.1 degree(the standard deviation is 5.20), and the mean rotary deformity in control groups was 2.52 degree(the standard deviation is 2.16)(p <0.01) CONCLUSION: The rotary deformity can be accompanied with degenerative spondylolisthesis. We may consider the rotary deformity as a cause of symptomatic degenerative spondylolisthesis in case that any other cause is not detected.

Objectives: The purpose of this study was to investigate the factors in which employee’s health beliefs affect their intention to get COVID-19 vaccines. Methods: The participants of this survey were 237 emlpoyees living in Busan. Data were collected using structured online questionnaires from April 26th to May 6th, 2021. The data were analyzed in SPSS WIN version 25.0 using descriptive statistics, t-test, chi-square test, multiple logistic regression analysis. Results: At the average score for each area of health beliefs regarding COVID-19, self-efficacy was 4.45 points, perceived sensitivity 4.71 points, perceived severity 3.59 points, perceived benefit 4.46 points, and perceived disability 2.19 points. Monthly income, perceived sensitivity, perceived severity, and perceived benefit were found to be factors affecting the intention to get COVID-19 vaccines. Conclusions In order to improve the vaccination intention of COVID-19, it is necessary for subjects to recognize the seriousness of the disease, increase their sensitivity to the disease, and actively promote and educate the community about the benefits of vaccination.
