We experienced a rare case of an epidural arteriovenous fistula, which presented with symptoms similar to those of cervical radiculopathy. An 18-years-old woman suffered from neck pain, which radiated to the left upper extremity for 4 months. On neurologic examination, there were sensory impairments of the left C4 to C8 dermatomes and intermittent weakness in both lower extremities after exercise. An MRI of the cervical spine demonstrated a mass, which produced a serpentine-like signal void within the spinal canal from C1 to C7. The feeding artery of the fistula and the arterialized epidural venous plexus within the spinal canal were found on vertebral angiography. One year after an endovascular embolization with platinum coils, the clinical symptoms resolved and complete resolution of the arteriovenous fistula was confirmed by angiogram and MRI scan.

Since the blastocyst is broken and spreads out on a flat plastic culture dish (two dimensional culture) during in vitro development, it has been difficult to study the implantation process. It also has been difficult to analyse the interactions between endometrial epithelial and stromal cells because of the lack of a long-term in vitro model which can stimulate in vivo characteristics, as these cells eventually fail to proliferate or cease to express differentiated functions. Recently nontransformed cell lines, CUE-P and CUS-V2, derived from rat endometrial epithelium and stroma were reported. In this study, morphology of CUE-P and CUS-V2 was examined and oxytocin gene expression by CUE-P cells was demonstrated by RT-PCR. The CUE-P cells have a cuboidal morphology and CUS-V2 cells resemble fibroblast and exhibit a spindle-like morphology. In RT-PCR, same size of PCR products of oxytocin gene at hypothalamus, uterus and CUE-P cells were demonstrated. These results showed three dimensional culture system could be made by using the new cell lines.

BACKGROUND AND OBJECTIVES: Coronary artery stenting actually shows a high efficacy in the treatment of coronary heart disease, but has the major limitation of restenosis. The ethylene-vinyl acetate copolymer (EVA), a biocompatible nondegradable copolymer, has been employed as a rate-controlling membrane in several drug delivery systems. Herein, the feasibility of an EVA-coated coronary stent was evaluated as a possible route for localized drug delivery. MATERIALS AND METHODS: A total of 15 rabbits were employed in this study. An uncoated stent was implanted into the non-diseased iliac artery in six rabbits, and an EVA-coated stent into a further nine. On the 30th day following the stent implantations, stented segments of the iliac arteries were removed for histological processing and morphometric analysis. RESULTS: The mean neointimal area of the uncoated and coated groups were 1.009 and 1.011 mm2 (p=0.56), respectively. No inflammatory cells were found in coated group. There were no apparent differences between the two groups. CONCLUSION: The results from this study have demonstrated that an EVA-coated coronary stent might be an appropriate method for the controlled-release of a drug.

Emergency surgical patients are more frequently in critical state than elective patients and they have not enough time for physical and laboratory examinations. The evaluation of perio-perative data will improve the outcome of emergency operation. We analyzed 1053 anesthesias for emergency operation which were performed at the department of anesthesiology, Anam Hospital from September 1992 to August 1993 clinically and statistically according to age, sex, physical status, department, anesthetic duration, method and agent, types of trauma, amount of transfusion, etc. The results were as follows; 1) The percent of emergency surgery cases was 13.6 of total surgical patients. 2) The ratio of male to female was 1.15:1. 3) About 61.1% of all emergency patients were in the 21-40 years age group. 4) According to the ASA classification of physical status, the percent of patients in emergency class 1 and 2 was 86.2 of the total patients. 5) The most common operation was Cesarean section (19.9%), and appendectomy (13.8%) the next. 6) The most common anesthetic method for emergency operation was general anesthesia with enflurane. 7) The obstetric cases were most common and the general surgery cases were the next. 8) The percent of the cases which took less than 2 hours duration was 82.4 of total operation. 9) The transfusion was done in 108 cases (10.3%) and less than 2 units was transfused most frequently. 10) The transference to ICU was done in 144 (13.7%) cases and the patients of general surgery were transfered to ICU most frequently. 11) The majority of injuries were classified as blunt trauma (86.6%) while 13.4% were classified as penetrating trauma. 12) The lagest number of injuries involved the upper extremity (47.8%) and the next was the head & neck (31.9%).

BACKGROUND AND OBJECTIVES: Plastic surgeons have generally avoided performing rhinoplasty in the presence of rhinosinusitis due to potential infection. For the otolaryngologist, concurrent rhinoplasty can produce increased periorbital swelling and ecchymosis, which can obscure the parameters used to monitor complications of the sinus procedure. But recent advances of endoscopic sinus surgery have made the simultaneous procedures safe in appropriately selected patient. The purpose of this report is to identify the indications and limitations of the simultaneous procedures. MATERIALS AND METHOD: Seven patients were treated by this combined modality and all were available for follow-up. There were 3 women and 4 men with a mean age of 35 years who underwent the combined procedure by the otolaryngologist. RESULTS: Recurrence of sinusitis occurred in one patient, and another patient wanted revision rhinoplasty for cosmetic dissatisfaction. There were no other complications. CONCLUSION: Combined rhinoplasty and endoscopic sinus surgery can be performed safely and with good results in selected patients.

BACKGROUND/AIMS: Acute exacerbation (AE) of chronic hepatitis B (CHB) can occur spontaneously, and may be followed by HBeAg clearance. HBeAg seroconversion often coincides with the normalization of liver biochemical tests and clinical remission. The purpose of this study was to identify the etiology and the clinical consequence of severe AE in Korean patients with CHB. METHODS: The medical records of CHB patients with severe AE (defined by the sudden increase of ALT above 400 IU/L) who were admitted to Kyung Hee University Hospital between January 1992 and December 2001, were reviewed retrospectively. Forty-four patients were included in the severe AE group. RESULTS: The most common etiology of severe AE was spontaneous exacerbation (77%). Drugs (16%), alcohol (5%), and HCV coinfection (2%) were suspected of causing AE in the remaining patients. HBeAg seroconversion at 12, 18, and 24 months following severe spontaneous AE was 18.5%, 40.7%, and 48.1%, respectively. These were significantly higher compared to CHB patients without AE (4.3%, 4.3%, and 10.9%, respectively). Seroconversion within 3 months, however, occurred in only 15% of CHB patients with AE. There was a tendency to progress to liver cirrhosis more frequently in the patients with AE as compared to the patients without AE (17.6% vs. 5.5%, P<0.08). CONCLUSIONS: Severe AE in patients with CHB is mainly caused by spontaneous exacerbation. Although HBeAg seroconversion occurs frequently in these patients, the rates are relatively low compared to those reported in other countries and early seroconversion is expected only in a small proportion. Further studies will be warranted to determine the efficacy of the early use of antiviral agents at the time of AE.

Background:
In Korea, the first community outbreak of coronavirus disease 2019 (COVID-19) occurred in Daegu on February 18, 2020. This study was performed to investigate the prevalence of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) antibodies in healthcare workers (HCWs) at 6 major hospitals in Daegu.
Methods:
Blood specimens of 2,935 HCWs at 6 major hospitals in Daegu from January 2021 to February 2021 were collected. Every specimen was tested for antibody against SARS-CoV-2 using both Elecsys Anti-SARS-CoV-2 electrochemiluminescence immunoassay (Roche Diagnostics, Rotkreuz, Switzerland) and R-FIND COVID-19 IgG/M/A enzyme-linked immunosorbent assay kit (SG medical Inc., Seoul, Korea) as screening tests. If 1 or more of these screening test results was positive, 2 additional antibody tests were performed using Abbott Anti-SARS-CoV-2 IgG assay (Abbott, Abbott Park, IL, USA) and cPass SARS-CoV-2 Neutralization Antibody Detection Kit (GenScript USA Inc., Piscataway, NJ, USA). If 2 or more of the total 4 test results were positive, it was determined as positive for the antibody against SARS-CoV-2.
Results:
According to the criteria of SARS-CoV-2 antibody positivity determination, 12 subjects were determined as positive. The overall positive rate of the SARS-CoV-2 antibody was 0.41% (12/2,935). Of the 12 subjects determined as positive, 7 were diagnosed with COVID-19, and the remaining 5 were nondiagnosed cases of COVID-19.
Conclusion
In early 2021, the overall seroprevalence of SARS-CoV-2 antibody among HCW located in Daegu was 0.41%, and 0.17% excluding COVID-19 confirmed subjects. These results were not particularly high compared with the general public and were much lower than HCWs in other countries.

PURPOSE: To determine the prevalence of scoliosis in volleyball athletes and compare this with the prevalence in the general population. MATERIALS AND METHODS: One hundred and sixteen volleyball athletes who had been enrolled in the activity for more than one year were examined for prevalence of scoliosis. The Adams forward bending test was performed with a measurement of the truncal asymmetry using a scoliometer (Orthopaedic System, Inc, USA). Those atheletes who showed more than 5degreesof measurement were selected for an X-ray evaluation. Data from a randomized point prevalence survey of Korean Middle school students (46,428) in Seoul City, which had been performed by our department, was adopted for the control group. RESULTS: Among the 116 volleyball players, 60 (51.7%) showed more than a 5degreesof angle of trunk rotation, whereas controls of middle school students showed 2.5%. Cobb's angle more than 10degrees was 6 (5.17%) in athletes and the control group was 465 (1.0%). Despite higher frequency of prevalence, the Cobb' angle was below 15degrees whereas the control group showed a severe scoliosis which of Cobb's angle reaching to 45degrees. CONCLUSION: Volleyball athletes showed a higher incidence of truncal asymmetry and scoliotic spinal columns than the control group. However, we were able to conclude that asymmetrical muscle development can produce a mild scoliosis. However this doesn't have the potential for a severe progression as found in some cases of idiopathic scoliosis.
