OBJECT: In order to compare several Obstetric characteristics and outmmes of teenage pregnancy. METHODS: The 10 year clinical records of 11,583 women undergoing Cesarean section and delivery were reviewed in the department of Obstetrics and Gynecology, Incheon Christian Hospital from July 1, 1989 to June 30, 1999. There were seventy-eight pregnancies under age 20 and we compared them with two hundred pregnancies aged 20-29 who were randomly chosen during the same periods as the control group. RESULT: The following results were obtained. The proportion of birth by teenagers increased from 0.5% of all birth in 1989 to 2.61% in 1999. The most of cases were in high teen group, age 14- 19.The majority(50.5%) were in the age of 19. Seventy two cases(92.3%) had no previous pregnant history. Six cases had one previous pregnant history. The frequencies of prenatal care were significantly lower than that of the control group(p<0.05). The mean gestational period was 36+4weeks, and showed significant difference between the study group and the control group(39+3 weeks). The incidence of preterm labor was significantly different between the two proups(p<0.05). But the incidence of postterm delivery were not significantly different between the two groups. The mean weight gain of pregnant teenagers revealed 10.64kg, significantly less profound than the control group. The matemal weight gain of control group revealed 12.95kg, respectively. The mean birth weight(2.54kg) of infant was significantly less profound than the control group. The incidence of birth of small for gestational age(birth weight 1,500-2,499gm ; 14.5%) was significantly increased among study group than the control group(1%). The rate of abdominal delivery(21.8%) were not significantly decreased than the control group(47%). The incidence of cephalopelvic disproportion and malpresentation for cesarean section were somewhat higher than the control group, and were statistically significant(p<0.05). During the antepartun period, anemia, pyelonephritis, and preterm labor occurred more frequently in the teenage pregnancy than the control group, but not statistically significant. Among postpartum complications, incidence of anemia(51.3%) increased significantly. The perinatal mortality, intrauterine growth retardation, congenital anomaly occurred more frequently than the control group. CONCLUSION: These results show that pregnancy of teenage will be comeout high risk and complications. And then we will be more concern and study about teenage pregnancy.

This research was focused on overall examination of tissue alteration, wound healing promotion. After the hair on the dorsal surface was shaved, 5x5mm oval skin defect was formed. Experimental wounds of right side were irradiated on every day for 90 second with Ga-Al-As semi-conductor laser. Left side wounds served as control group. The rats were sacrificed on the 1st, 3rd, 5th, 7th, 14th, 21th day. For light microscopically, parafin section were stained with H&E, MT. The outcomes were as follows : 1. On 1st day, experimental and control group were seen acute inflammatory cell infiltration, edema. 2. On the 3rd days, both groups were seen crust development, collagen, blood vessel proliferation. 3. On the 5th days, experimental group were reduced edema and inflammatory cell infiltration than control group. 4. On the 7th days, both groups were observed edema, inflammatory cell infiltration disappearance and keratinocytes motility from wound defect. 5. On the 14th days, experimental group appeared collagen, blood vessel proliferation and hair follicle than control group. 6. On the 21th days, both groups were seen normal status re-epithelization. According to the above results, The wound-healing stimulated by laser radiation involves an increased rate of epithelial growth. LLLT was confirmed that it has fibroblast, blood vessel proliferation, influence initial wound healing process.

OBJECT: In order to estimate the frequency and risk factors for adenomyosis. METHOD: The clinical records of 1127 women undergoing hysterectomy were retrieved in the Department of Obstetrics and Gynecology, Incheon Christian Hospital, during 7 years, from Jan. 1st 1991 to Dec. 31st 1997. RESULT: The following results were obtained. 1. Adenomyosis was found in 206 of 1127 patients(18.3%). 2. The highest incidence was 41-50 years of age group, an incidence of 55% and mean age group was 46.9 years. 3. Adenomyosis was more frequently observed in parous woman than non-parous woman, such as 8.3% and 91.7%, respectively. 4. Grossly, the size of uterus was enlarged more than 10 weeks gestational size in adenomyosis, an incidence of 62.4%. 5. Pelvic pain, dysmenorrhea and metrorrhagia were common symptom of adenomyosis, an incidence of 26.7%, 25.2% and 19.4%, respectively. 6. Myoma was the most combined disease in adenomyosis, showing the incidence of 53.4%. 7. Combined pelvic endometriosis was not observed in this study. 8. Endometrial findings of adenomyosis showed proliferative phase of normal endometrial cycle in the highest incidence, giving 72.3% of all cases. 9. Preoperative diagnostic accurracy of adenomyosis was 8.2%. CONCLUSION: This results show that deeply understanding of the common symptom and epidemiology of adenomyosis improve the preoperative diagnostic accuracy.

PURPOSE: Bone bruises of patients with acute traumatic knee injuries, that are not found on simple radiograph, can be found on magnetic resonance imaging (MRI). The purpose of this study is to evaluate the frequency and locations of bone bruises on MRI in acute traumatic anterior cruciate ligament (ACL) or posterior cruciate ligament (PCL) injury. MATERIALS AND METHODS: 25 and 19 MRls, in which acute traumatic ACL and PCL injury was pre sent and there was no abnormality in simple radiograph, were reviewed. MRI was taken within 51 days of injury. A bone bruise was determined as a geographic and nonlinear area of signal loss on T1 images and increased signal intensity on T2 images involving the subcortical bone. RESULTS: In 16 patients with bone bruises and acute ACL injury, bone bruises were found in the lateral compartment of the knee in 15 (93.8%) patients. The most common area was the lateral tibial plateau (11 cases, 68.8%) and the second was lateral femoral condyle (9 cases, 56.3%). In 5 patients with bone bruises and acute PCL injury, bone bruises were found in the lateral compartment of the knee in all 5 (100%) patients. The most common area was lateral tibial plateau (4 cases, 80%) and the second was lateral femoral condyle (2 cases, 40%). CONCLUSIONS: In patients with acute traumatic ACL or PCL injuries the bone bruises are often found on the lateral compartment of the knee, especially lateral tibial plateau and lateral femoral condyle on MRI.

PURPOSES: There have been many efforts to improve the service of emergency centers. In spite of these, no evidence is showing any landmark advancement of emergency services, especially in the hospital stage, exists. We need some efficient standard criteria to evaluate emergency service in the hospital stage, and a useful method might utilize the overcrowding index. We want to know the change in the overcrowding index at a regional emergency center after injury area administration. Injury area means an area in which only an assigned duty physician manages patients with injuries such as those from traffic accidents, falls, assualts, collisions, lacerations, amputations, burns, intoxication, asphyxia, drowning, animal bites, sexual assualts, etc. METHODS: We started to operate an injury area in our emergency department from late 2004, and from January to June in 2004 and in 2005, we collected patients' data, age, sex, assigned department, and result from hospital order communication system to figure out overcrowding indices and result indices. We found the daily number of patients, the turnover rate, the admission rate, the ICU admission rate, the emergency operation rate, the ED stay duration, and the ED patient volume to be overcrowding indices. Also we found the withdrawal rate, the transfer rate, and mortality to be result indices. We compared these indices between 2004 to 2005 by using a t-test. RESULTS: There was a significant increase in the daily number of visiting patients in 2005, overcrowding indices, such as the turnover rate, the admission rate, the ICU admission rate, and the emergency operation rate, also showed statistically significant increases in 2005 (P<0.001). As for the result indices, there was a noticeable decrease in the number of withdrawals (11.77/day in 2004 to 4.53/day in 2005). CONCLUSION: Operating an injury area in a mildly overcrowded local emergency center is beneficial. Evaluating the effect of operating an injury area and it's impact on hospital finances by conducting a similar study analyziing patients for a longer duration would be valuable.

Spondyloepiphyseal dysplasia (SED) tarda is an inherited skeletal arthropathy. Because SED tarda involves the joints and resemble the clinical findings of chronic arthropathies, this disease is frequently misdiagnosed as juvenile idiopathic arthritis (JIA). We report here on three patients (father and his two daughters) in one family with SED tarda. All patients had back pain and polyarthralgia. Their radiographs revealed typical changes for SED tarda including platyspondyly and dysplastic bone changes. This rare disease has major clinical importance in that it is similar with JIA or rheumatoid arthritis.

Superior sulcus or pancoast tumor refers to any primary lung cancer locating in thoracic inlet and causing pain in the periscapular region or arm. These originate in peripheral, and involve the extrapulmonary structures more than arenchyma of the lung. We experienced 1 case of superior sulcus tumor radically resected via anterior transcervical approach, which provided more safe exposure of cervical structures of thoracic inlet than classic posterolateral thoracotomy. Therefore we report this case with review of literature.

OBJECTIVE: Recently some reports suggested substance P and CGRP might be important factors for inflammation and hyperalgesia. This study was performed to see whether substance P or CGRP containing nerve fibers might be changed by mustard oil-induced inflammation. METHODS: After injection of mustard oil(5%) into uterine lumen, the uteri were removed and examined with immunohistochemical methods for substance P and CGRP. RESULTS: In the normal uterus, most of the substance P- or CGRP-immunoreactive nerve fibers were observed along the vascular structure and some in the myometrium, only few in the endometrium. Mustard oil did not changed this pattern of nerve fiber distribution but after 48 hrs, the amount of substance P or CGRP immunoreactive nerve fibers were greatly reduced compared with the normal uterus. It is not clear whether the decrease of substance P and CGRP immunoreactive fibers in the uterus was resulted from the depletion of the neuropeptides in the nerve fibers or the retraction of nerve fibers. CONCLUSIONS: These results suggest that the inflammation should cause the change of nerve fibers included in the nociception. This change may attribute the generation of inflammation and inflammatory hyperalgesia.

BACKGROUND AND OBJECTIVES: QT dispersion (QTd) represents the inhomogeneity of ventricular repolarization and has been suggested to predict ventricular arrhythmia in patients with coronary artery disease (CAD). This study investigates the short-term effect of percutaneous transluminal coronary angioplasty (PTCA) on QTd in patients with CAD and no history of previous myocardial infarct. MATERIALS AND METHODS: In 84 angina patients (65 men and 19 women, mean age of 58.3+/-9.0 yeras) who underwent successful PTCA of single coronary artery, ECG was checked in baseline, immediate, 1day and 1 month after PTCA. QTd and corrected QTd (c-QTd) were measured in these ECGs by digitizer. RESULTS: PTCA was performed at left anterior descending artery (LAD) in 56, left circumflex artery (LCx) in 12 and right coronary artery (RCA) in 16 patients. Mean and standard error of QTd (c-QTd) at baseline, immediate, 1day and 1month after PTCA was 51.3+/-4.2 (50.7+/-4.1), 54.2+/-4.5 (52.8+/-4.5), 47.7+/-4.3 (48.5+/-4.8) and 36.3+/-4.5 (37.5+/-4.6)msec, respectively. QTd and c-QTd significantly decreased at 1 month following PTCA. The difference was more prominent in pateints with LAD lesion than LCx or RCA lesion and independent of gender, severity of stenosis and use of beta-blockers. CONCLUSION: QTd decreases in CAD patients with no history of myocardial infarct at 1 month following successful PTCA. This may facilitate a favorable recovery from inhomogenous repolarization. These findings call for long-term follow-up of QTd and the incidence of ventricular tachyarrhythmias and sudden death following successful PTCA.
