OBJECTIVE: Uterine cervical cancer is the most common malignant tumor in Korean women. Human papillomaviruses are associated in 85-90% of the cases. However, other cofactors are considered to be important in carcinogenesis. There is an evidence that the uterine cervix is the site of shedding of the Epstein-Barr viruses(EBV). Furthermore the virus has been detected in cervical intraepithelial neoplasia and invasive carcinoma of the uterine cervix. We studied to evaluate the role of EBV in cervical carcinogenesis. METHODS: Non-neoplastic cervices(12), carcinoma in situ(32), microinvasive squamous cell carcinomas(9), invasive squamous cell carcinomas(37) and adenocarcinomas and adenosquamous carcinomas(14) were studied for EBV infection. PCR and in situ PCR for EBNA-1 were done and subtyping was done using PCR for EBNA 3C. RESULTS: In non-neoplastic cervix, EBV was detected in 16.7% by PCR and found in normal epithelial cells and lymphocytes in in situ PCR. By PCR technique, EBV was detected in 65.6% of CIS, 66.3% and 51.4% of microinvasive and invasive squamous cell carcinomas, 57.1% of adenocarcinomas and adenosquamous carcinomas. EBV subtyping was done in EBV positive cases by PCR and all showed type 1. CONCLUSION: EBV was detected in higher frequency in cervical cancer than in non-neoplastic cervix. However the frequency was not correlated to the invasion depth and histologic types of cervical carcinomas. EBV was detected in tumor cells as well as normal epithelial cells and lymphocytes also. It was suggested that EBV may play a role in cervical cancers but the mechanism in carcinogenesis remains to be solved.

BACKGROUND: Headache is a common complaint in patients presenting to the emergency department(ED). Many patients suffered sustained headache even after presenting to the ED. This study investigate whether the patients were received analgesics and timely adequate. METHOD: We analyzed 131 adolescent and adult patients with non-traumatic headache without any neurologic deficit in two emergency department during 6 months period retrospectively. RESULTS: The positive and negative predictive value according to primary impression were 47% and 74% respectively. The mean time to take brain computed tomography(CT) after ED presentation was 120 minutes. The patients with primary impression of intracranial hemorrhage(mainly SAH) were the most fast(mean time 88+/- 70 minutes). 28(21%) patients were received analgesics before taking brain CT(after ED presentation), and 70(53%) patients after CT, 27(54%) patients after cerebrospinal fluid examination. The mean time interval were 43, 126 and 149 minutes on each group being received the analgesics. CONCLUSION: According to this study many patients suffered sustained headache before being classified to certain type of disorder. It may due to the reasons that there were no definite guidelines treating headache, the pain itself, or the physician treats patients as physician's way.

Classification of meniscal tear is necessary only for partial resection. In western countries many reports said that medial meniscal tear is commoner than that of lateral meniscus. Actually the reverse is true in Korea and in some other oriental countries, However there is no plausible explanation concerning this matter. In this report 250 knees of 240 patients were involved. We performed arthroscopic meniscectomy in all cases and we investigated the relationship between the pattern of tear and many possibly related factors. The follow-up period was 1–8 years, the ratio of male-female was 163:77, and the range of age was varied between 7 and 71 tears with the young and middle age groups being predominant. Right and left side ratio was 117:113 and the involvement of both knees was noted in 20 knees of 10 patients. The results were as follows: 1. The medial menisci were torn in 100 knees and was less than 142 lateral meniscal tear, with the ratio being 1:1.4. The tear of lateral meniscus was commoner in the age group of less than 30 years and the tear of medial meniscus was commoner in the age group older than 50 years whereas there was no difference in the age group of inbetween. 2. The commonest pattern of tear was longitudinal one including peripheral tear, that is 135 knees (54.0%), followed by complex tear, 50 knees (20.0%), oblique tear, 40 knees (16.0%), horizontal tear, 21 knees (8.4%) and lastly superior and inferior flap tear, 5 knees (2.0%). 3. The longitudinal tear was most prevalent in the age group of 20–40, whereas the complex tear was most prevalent in the age group of beyond 50 years (p<0.05). 4. The longitudinal tear was significantly prevalent in lateral menisci, the complex tear in medial menisci (p<0.05), whereas the transverse and oblique tear were not significantly prevalent in either meniscus (p>0.05). 5. In the longitudinal tear group, the tear occured most frequently in the midsubstance of posterior portion in the medial menisci without statistical significance (p>0.05) wereas the tear occurred most frequently in the periphery of the anterior portion in case of lateral menisci (p<0.05). 6. There were 37 discoid lateral menisci, with the longitudinal tear being the commonest. 7. Ground sports injuries occurred only in 34 knees (13.6%), with the longitudinal tear being significantly commoner than in the other injuries. From these results it would be suggested that although the discoid lateral meniscus has to be given much weight in the total meniscal injuries another explanation should be given concerning the prevalence of lateral meniscus tear compared to the medial meniscus tear and the prevalence of longitudinal tear.

OBJECTIVES: Radiofrequency(RF) ablation is an effective and low risk curative treatment for supraventricular arrhythmias. Catheter ablation produced cardiac lesions primarily through formation of coagulation necrosis. We evaluated the degree of myocardial injury after RF catheter ablation by means of serial measurement of myocardial enzyme. METHODS: Fifty-one patients with symptomatic supraventricular tachycardia were included. There were 32 men and 19 women(mean age. 39.5+/-15.4 years)All patients underwent electrophysiologic study to detect accessary pathway and ablation with radiofreguency current. A mean of 18.3+/-14.2 radiofrequency pulses were delivered. The pulses were at a power of 50 to 60 Volts for a duration of 20 to 30 seconds. Unipolar method and a 6F or 7F catheter with a 4 mm tip electrode was used. LDH, CPK and Ck-MB as a kind of cardiac enzyme were measured before and after ablation. RESULTS: 1) The concentration of LDH and CPK were elecated at 8 hours and 16 hours after ablation (p<0.05). 2) The concentration of CK-MB was elevated at 8 hours, 16 hours, 24 hours and 72 hours after ablation(p<0.05). 3) There was no correlation between the number of applications and amounts of radiofrequency current and rise in LDH, CPK, CK-MB concentration. CONCLUSION: The concentration of LDH, CPK and CK-MB were elevated after ablation but they were within normal limits. RF catheter ablation produced myocardial damage inevitably but were within normal limits. RF catheter ablation produced myocardial damage inevitably but minimally, then RF ablation is an effective and safe therapeutic modality for patients with symptomatic tachyarrhythmias.

During a 12-month period high-resolution, real-time ultrasonography (US) with graded compression was performed on 268 consecutive patients with clinically suspected acute appendicitis and its complication. US visualization of a fluid-filled, non-compressed appendix or a decompressed, thick-walled appendix was the primary criterion for a diagnosis of acute appendicitis. The sonographic findings were correlated with surgical-pathologic outcome in 92 cases and with the findings of clinical follow-up in the remainder. US was found to be accurate in the diagnosis of acute appendicitis and its complication with a sensitivity of 93.3%, a specificity of 98.9%, and an accuracy of 97%. The predictive value of a positive test was 97.7%; that of a negative test was 96.7%. There were two false-positive examination in patients with a thick-walled appendix or periapperdiceal abscess, which were surgically confirmed as appendiceal adenocarcinoma and perforated cecal diverticulitis respectively. There were six false-negative examination in patients with a sonographically no-visible appendix, which were confirmed surgically as acute appendicitis(n=5) and perforated appendicitis(n=1). Our results show that high-resolution, real-time US is an accureate imaging modality in the diagnosis of acute appendicitis and the evaluation of its complication.

Dentocutaneous fistula of the face neck is an infrequent manifestation of chronic dental infection. A periapical dental abscess may be initiated by disease, trauma, or thermal or chemical injury and develops into an extensive necrosis of surrounding tissue. Diagnostic errors can result in multiple excision, biopsies, and ineffective long-term antibiotic therapy. Awarness that periapical dental abscess is the most common etilolgic factor of cutaneous sinus tracts involves the face & neck will facilitate their early diagnosis and prevent needless treatment or anxiety for the patient. From 1994 to 1998, we have performed 6 cases of dentocutaneous fistula. Among of them, three were men and the others were women, age ranged from 18 to 66-year-old, and morbidity period was from 3 weeks to 3 years, the follow-up period ranged from 5 to 18 months (mean period 11 months). In conclusion, an understanding of the pathogenesis of cutaneous fistulae arising from dental infections will lead to proper early diagnosis and treatment without unnecessary surgery.
