  • Recently, the use of electronic drug information databases has been increased alternative to printed references. However, databases vary widely in quality and quantity of drug information provided and many questions have arisen about their accuracy, completeness, and reliability. This study was designed to compare and evaluate the drug information contained in four Korean drug information databases which are available on CD-ROM and internet. Four Korean drug information databases selected to be evaluated were eKIMS, Datapower, KPA Standard Drug Information and Korean Drug Formulary. Databases were searched and evaluated from August 10 to September 30, 2000 by the same trained searcher to minimize the bias. The database evaluation form was developed for objective evaluation of each databases in terms of credibility of database, convenience of use and other characteristics. The second form was developed for quantitative and qualitative assessment of the drug information provided by the databases. The results of the study showed that there were no significant differences in 4 databases in terms of convenience of use and other characteristics. However, for credibility of databases, Korean Drug Formulary was significantly superior to all other databases (P<0.05). It showed that information provided by Korean Drug Formulary was the best in terms of pharmacokinetics, chemistry, comparisons and eKIMS was the best in terms of drug identification (P<0.05). For accuracy and completeness of information provided, the study could not find a significant difference between 4 databases (P>0.05).

  • Background Venous malformations (VMs) are the most common type of vascular malformations. Intramuscular venous malformations (IMVMs) are lesions involving the muscles, excluding intramuscular hemangiomas. The purpose of this study was to compare clinical outcomes between patients with IMVMs who were treated with sclerotherapy and those who were treated with surgical excision. Methods Of 492 patients with VMs treated between July 2011 and August 2020 at a single medical center for vascular anomalies, 63 patients diagnosed with IMVM were retrospectively reviewed. Pain, movement limitations, swelling, and quality of life (QOL) were evaluated subjectively, while radiological outcomes were assessed by qualified radiologists at the center. Complication rates were also evaluated, and radiological and clinical examinations were used to determine which treatment group (sclerotherapy or surgical excision) exhibited greater improvement. Results Although there were no significant differences in pain (P=0.471), swelling (P=0.322), or the occurrence of complications (P=0.206) between the two treatment groups, the surgical treatment group exhibited significantly better outcomes with regard to movement limitations (P=0.010), QOL (P=0.013), and radiological outcomes (P=0.017). Moreover, both duplex ultrasonography and magnetic resonance imaging showed greater improvements in clinical outcomes in the surgical excision group than in the sclerotherapy group. Conclusions Although several studies have examined IMVM treatment methods, no clear guidelines for treatment selection have been developed. Based on the results of this study, surgical excision is strongly encouraged for the treatment of IMVMs.

  • Gentamicin-loaded bone cement used in total joint arthroplasty is indispensable, as it provides stability by directly binding the surfaces of implants and bones. Depending on multiple factors, including the material of the bone cement used, common complications, such as aseptic loosening, osteolysis, and infection can occur postoperatively. In clinical practice, Doujet bone cement is easy to handle (pre-packed all-in-one system), and has shown low failure rates and non-inferior results compared with similar available products. We conducted a retrospective comparative study to analyze the clinical and radiological results of each bone cement group to establish the safety and usefulness of Doujet bone cement. From July 2020 to July 2022, we enrolled 198 patients in this study after an average follow-up period of 37 months (range, 6-48 months). In 99 patents, Doujet® bone cement (Injecta, Gunpo, Korea) was used for total knee arthroplasty (TKA), while Refobacin® bone cement (Biomet, Warsaw, IN, USA) was used in 99 patients. The average range of motion (ROM) of the knee increased by 2.4° (from 127.0° preoperatively to 129.4° postoperatively) in the Doujet group, and by 0.1° (from 128.7° to 128.8°) in the Refobacin group (P=0.701). The Western Ontario and McMaster Universities (WOMAC) osteoarthritis index scores decreased from 44.1 to 7.8 in the Doujet group, and from 44.2 to 6.3 in the Refobacin group (P=0.162). Complications, such as osteolysis or post-operative wound infection, did not occur in more than two cases in both groups. The WOMAC and ROM of the knee in both groups had no clinical differences. Both Doujet and Refobacin similarly showed low complication rates after TKA.

  • Objective : The incidence of spontaneous spinal epidural hematoma (SSEH) is rare. Patients with SSEH, however, present disabling neurologic deficits. Clinical outcomes are variable among patients. To evaluate the adequate treatment method according to initial patients' neurological status and clinical outcome with comparison of variables affecting the clinical outcome. Methods : We included 15 patients suffered from SSEH. Patients were divided into two groups by treatment method. Initial neurological status and clinical outcomes were assessed by the American Spinal Injury Association (ASIA) impairment scale. Also sagittal hematoma location and length of involved segment was analyzed with magnetic resonance images. Other factors such as age, sex, premorbid medication and duration of hospital stay were reviewed with medical records. Nonparametric statistical analysis and subgroup analysis were performed to overcome small sample size. Results : Among fifteen patients, ten patients underwent decompressive surgery, and remaining five were treated with conservative therapy. Patients showed no different initial neurologic status between treatment groups. Initial neurologic status was strongly associated with neurological recovery (p=0.030). Factors that did not seem to affect clinical outcomes included : age, sex, length of the involved spinal segment, sagittal location of hematoma, premorbid medication of antiplatelets or anticoagulants, and treatment methods. Conclusion : For the management of SSEH, early decompressive surgery is usually recommended. However, conservative management can also be feasible in selective patients who present neurologic status as ASIA scale E or in whom early recovery of function has initiated with ASIA scale C or D.

  • Background and Objectives There was no clinical data except literary study on mutual correlation with autistic disorder in Western medical diagnosis and five kinds of flaccidity in infants(五軟), five kinds of retardation(五遲) in Oriental medical diagnosis. This study was performed to investigate the correlation of five kinds of flaccidity in infants(五軟), five kinds of retardation(五遲) to the children with autistic disorder and to set the time table for clinical diagnosis of developmental retardation by making a comparative study of normal developmental children so we can treat the children with autistic disorder in good time. Method We made the comparative study of interview sheets recorded by parents of total 163 children who were diagnosed as autistic disorder who visited HaeMa Oriental Medical Clinic with interview sheets recorded by parents of generally accepted normal developmental children(263) and then we took statistics. Results : 1. There was significant correlation with speech and walking among five kinds of flaccidity in infants(五軟), five kinds of retardation(五遲) in autistic disorder statistically and clinically in comparison with normal children. 2. There wasn't significant correlation with growth time of tooth among five kinds of flaccidity in infants(五軟), five kinds of retardation(五遲) on diagnosis of autistic disorder in comparison with normal children. 3. There was significant correlation with retardation of times going to toilet by oneself (it does not consist in five kinds of flaccidity in infants(五軟), five kinds of retardation(五遲).) in both of autistic disorder. Conclusion Autistic disorder was significantly correlated with the faculty of speech(語遲), retardation in walking out(行遲) of five kinds of flaccidity in infants(五軟), five kinds of retardation(五遲). We need to concrete the index of diagnosis, because it is so difficult to measure times and register retardation in tooth eruption(齒遲), retardation in hair-growing(髮遲), debility of neck and nape(頭項軟), flaccidity of extremities(手軟) and flaccidity of muscle(肌肉軟). And we can also use times going to toilet by oneself as one of diagnostic criteria because of its significant correlation. It is required to make early diagnosis of five kinds of flaccidity in infants(五軟), five kinds of retardation(五遲) using these criteria, and to treat them early by oriental medicine.

  • In order to study the role of LATS in the pathogenesis of the Graves' disease, the serum activity of the LATS was determined by the bioassay of the modified McKenzie method. The subjects examined in the study consisted of 76 individuals including 12 cases of normal control, 54 cases with typical Graves' disease and 10 cases of chronic thyroiditis. The data observed in the patients with the Graves' disease were analyzed in comparison with the clinical features, laboratory findings, and responsiveness to the treatment. The results obtained are as follows: 1. None of the subjects which did not have the Graves' disease showed a positive LATS activity, except one case with the chronic thyroiditis. 2. Twenty-two out of the 54 cases with the Graves' disease showed positive results for LATS(40.7%). The positivity was significantly higher in the patients who had been treated with anti. thyroid regimen but still showed hyperthyroidism than in the patients who had not been treated. 3. The activity of LATS was gradually decreased or even became absent as the hyperthyroidism was corrected after the treatment. 4. No significant difference was noticed in age & sex between the positive and negative groups of LATS. 5. There was no evidence of significant correlation between the LATS activity and clinical features.

  • During aortic valve surgery, cardioplegic solution is delivered through direct cannulation of both coronary ostia. Since this approach may cause an intimal injury leading to acute dissection or late ostial stenosis, this study was undertaken to evaluate myocardial protective effect of retrograde perfusion of cardioplegia [RCSP <% RRAP] in 18 clinical cases, which were compared with antegrade perfusion of cardioplegia in 27 clinical cases. This study were investigated 1] cease and return of electromechanical activity after cardioplegia infusion 2] the myocardial temperature during operation 3] the aortic cross clamping time and total bypass time 4] frequency of DC shock for defibrillation 5] need for inotropic drugs after operation 6] electrocardiographic evidence of myocardial infarction or ventricular arrhythmia after operation 7] the enzymes activity during preoperative and postoperative period as an evaluation of myocardial ischemic injury and 8] operative mortality rate The combination of retrograde cardioplegia and topical cooling with ice slush yielded promptly hypothermia of myocardium and shorter aortic cross-clamping time compared with antegrade cardioplegia [P < 0.05]. The temperature of the interventricular septum was maintained below 20oC by continuous perfusion or intermittent perfusion of cold blood cardioplegia and other results were no statistically significant difference between the two methods [P >0.05]. This technique provides clear operative field and avoids some serious complications which are caused by coronary ostial cannulation. These results suggested that the retrograde perfusion of cardioplegia is a simple, safe, and effective means of myocardial protection during open heart surgery.

  • Atherosclerosis, which is a degenerative vascular disease, is believed to occur in the blood vessels due to deposition of cholesterol or low density lipoprotein (LDL). Atherosclerotic lumen narrowing causes reduction of blood flow due to hemodynamic features. Several hypothetical theories related to the hemodynamic effects have been reported : high shear stress theory, low shear stress theory, high shear stress gradient theory, flow separation and turbulence theory, and high pressure theory. However, no one theory clearly explains, the causes of atherosclerosis. The objective of the present study was to investigate the mechanism of the generation of atherosclerosis. In the study, the database of Korean carotid and coronary arteries for geometrical and hemodynamic clinical data was established. The atherosclerotic sites were predicted by the computer simulations. The results of the computer simulation were compared with the in vivo experimental results, and then the pathogenesis of atherosclerosis by using the clinical data and several hypothetical theories were investigated. From the investigation, it was concluded carefully that the mechanism of the generation of atherosclerosis was related to the hemodynamic effects such as flow separation and oscillatory wall shear stress on the vessel walls.

  • Purpose: The purpose of this study was to develop a fundamental reference for the clinical implementation of Complementary and Alternative Therapy(CAT) by surveying and analyzing different perception and attitude between nurses and physicians. Method: A total of 167 nurses and 103 physicians from two C university health science centers participated in this survey, and SPSS program with version 10.0 was used to analyze the result of survey. Result: As results, 72.7% nurses and 57.1% physicians showed positive attitude for the concept of CAT, 60.6% nurses and 36.7% physicians responded positively while 2.6% nurses and 25.9% physicians responded negatively for the application of CAT to the clinical practice. There was a meaningful difference between two groups in the belief of therapeutic effectiveness of CAT. 67.7% nurses believed the therapeutic effectiveness of CAT while 38.8% physicians did. For attitudes of nurses and physicians toward CAT showed meaningful difference according to general characteristics: age, gender, marital status, a level of education, position in the organization, religion, and duration of health care service other than inpatient units. Conclusion: In this study, the attitudes of nurses and physicians about CAT showed meaningful difference that nurses were more positive than physicians in application.
