Computed tomographic findings of 24 cases of cervical tuberculous lymphadenitis were retrospectively analyzed. We classified the CT findings as 4 types: type 1(homogeneous soft tissue density mass), type 2(central low density with peripheral rim enhancement and with preservation of surrounding fat plane), type 3(central low density with peripheral rim enhancement and with obliteration of surrounding fat plane), type 4(large confluent low density mass, so called "cold abscess") As a result, there were 2 cases(8.3%) of type 1, 7 cases(29.2%) of type 2, 9 cases(37.5%) of type 3, 3 cases(12.5%) of type 4, 1 cases(4.2%) of type 1 combined with type 3, and 2 cases(8.3%) of type 2 combined with type 4. So 22 cases(91.7%) revealed central low density and peripheral rim enhancement, which suggest necrosis. The maximum thickness of enhancing rim was above 2mm in all of 64 definable necrotic lymph nodes and above 4mm in 42(65.5%) lymph nodes, suggesting that the wall of necrotic tuberculous lymphadenitis tends to be thick. We conclude that CT is useful not only for the diagnosis but also for the evaluation of the extent and the status of cervical tuberculous lymphadenitis.

We introduce a new silicone implanting method to correct facial depression caused by trauma or congenital anomaly. It resulted in good facial aesthetics in patients with facial depression. From August 1997 to January 1999, 5 patient (3 males and 2 females), in ages from 19 to 34 years, underwent silicone implantation for facial depression using our method. Three males were injured by traffic accident and had facial depression with or without bone defect. Two females had congenital forhead depression and requested aesthetic contouring. An impression of the face was taken with alginate backed with quick setting plaster. When set, a further stone plaster model was taken from the alginate-plaster, which was removed after fixation. Wax was then carved into the patient's stone model to fill the depression. Another stone cover was taken to cover this was-stone model. Then wax was melted away and medical implant grade room temperature vulcanized silicone adhesive was squeezed into the empty space. After cured, this precisely-shaped silicone imlant was inserted into the patient. We did not experience major complicaion such as infection, implant extrusion during 4 to 18 months' follow-up periods. All patients were satisfied with the results. The clinical result of this technique would be useful for accurate and excellent aesthetic implantation.

BACKGROUND: Coronary arteriovenous(AV) fistula is a rare congenital disease, and seldom produce symptoms during childhood. However late complications can occur including congestive heart failure, myocardial ischemia, and bacterial endocarditis. Therefore surgical repair is recommended even if the patients are asymptomatic. In these days many investigators are interested in transcatheter embolization because of high procedural success rate without risks and morbidity associated with cardiac surgery. METHODS: Five patients(4 females and 1 male) of coronary AV fistula were treated with transcatheter coil embolization. All had symptom of chest pain. In coronary angiograms fistulous tracts were originated from left anterior descending artery(LAD) and drained to main pulmonary artery(MPA) in 4 cases. The other case had abnormal vessel from left circumflex artery(LCX) to bronchial artery. Transcatherter coil embolization were done with Judkins left guiding catheter, 018 inch Tracker or 3F Microferret catheter, and 018 inch coils. RESULTS: The fistula tracts were completely occluded in 3 cases after coil emboilzation. In 2 cases with multiple fistular vessels, major fistula were occluded, but minor vessels remained. There were no procedure related complications. CONCLUSION: Transcatheter coil embolization may be an effective treatment modality in coronary AV fistula with excellent result and minimal complications.

BACKGROUND: Exposure to hyperoxia causes extensive injury to lung tissue, which resembles the pathologic changes of the adult respiratory distress syndrome. To observe the relationship between the pulmonary oxygen toxicity and duration of exposure to oxygen, 100% oxygen was exposed to Wistar rats. METHODS: 35 rats were partitioned into 5 groups (n=7 in each group). Gr. I breathed room air. Gr. II, III, IV and V were exposed to 99~100% oxygen for 24 hrs, 48 hrs, 60 hrs and 72 hrs. Wet lung/body weight (WW/BW), dry lung/body weight (DW/BW), wet/dry lung weight (WW/DW) and I-albumin flux ratio were measured in each group. RESULTS: After exposure for 72 hrs in Gr. V, 3 rats were dead. WW/BW in Gr. I was 0.69+/-0.04 and increased to 1.10+/-0.28 in Gr.II (P<0.05), which was maintaind until 60 hrs. It showed marked increase in Gr. V; 2.16+/-0.60. DW/BW, WW/DW and I-albumin flux ratio increased after 48 hrs of hyperoxia. WW/BW and DW/BW in Gr. V and I-flux ratio in Gr. IV showed significant increase compared with Gr. I, II and III. CONCLUSIONS: The results suggest that pulmonary capillary permeability begins to change after 24 hrs of hyperoxia and that definite permeability change to albumin and fluid accumulation in the lung are demonstrable from 48 hrs-exposure to 99~100% oxygen and aggravated by duration of oxygen exposure.

PURPOSE: Leptin is a hormone, encoded by ob gene in adipocytes and regulates food intake and energy expenditure. The serum concentration of leptin is known to be proportional to the amount of body fat but the regulation of leptin for growth and development in childhood is not clear. The purpose of this study is to evaluate the correlation of serum leptin levels to gender, pubertal development and sex steroid in children. METHODS: Serum leptin levels were measured by RIA in 145 Korean children of both sexes, age 8-16yr, and were compared according to body mass index, gender and pubertal stage. The correlations of leptin with testosterone and estradiol were also analized. RESULTS: A positive relationship was observed for leptin levels with body mass index(in male:r=0.63, P<0.001, in female:r=0.80, P<0.001). The mean leptin level of girls was higher than that of boys(7.50+/-.83ng/mL vs 4.11+/-.72ng/mL, P<0.05) in lean children but there was no significant difference in obese group. An analysis according to the pubertal development showed an increase of leptin level in girls while leptin decreased in boys at overt puberty. Serum leptin levels of boys in puberty correlated inversely with testosterone(r=-0.52, P<0.001) but leptin of girls did not have significant correlation with estradiol. CONCLUSION: Serum leptin level increases in girls and decreases in boys as the pubertal development proceeds. The relationships between leptin level and pubertal developement show gender difference and it might be explained in part by suppressive effects of androgen in male.

BACKGROUND: Recently in Korea, the rate of addictive drug abuse is rapidly increasing in men on salary, housewives, and even in adolescents, who have been considered to be free from drugs, which presents a serious problem to the society. Especially, the habituation to gateway drug, such as cigarettes and alcohol, before 15 years old, would lead to the increased possibility of other drug abuse, including illicit drugs. Thereupon in this study, we intended toreview the effect of adolescents smoking an the drug abuse and deviated behaviors. METHODS: On September, 1997, randomly selected were 12 classes, an the basis of 2 classes per grade, from the two schools which was located each in Seoul and Buchean. And survey was dane on 610 students with non non-nominl, self-reported questionnaire. RESULTS: The rate of adolescent smoking was 28.1% in male students and had increasing tendency of "the higher the grades, the higher the smoking rate"(17.0% in the 1st gade, 31.5% in the 2nd grade, 35.9% in the 3rd grade). The smoking rate of female students was 12.3%. From the 2nd grade of middle school to the 2nd grade of high school was the critical period when the smoking habit was initiated in almost 90% of the students. The experiencing rates of drug abuse in studied subjects were as follows : drinking(79.0%), stimulants(4.8%), sedatives(4.1%), hypnotics(3.1%), glue sniffing(1.5%), butane gas(0.7%), marijuana/hemp(0.2%). They were higher in the smoking group than in the nansMoking group, showing statistical significances in most items except hypnotics and marijuana/hemp. Also simihr results were shown in deviated behaviors between the groups. CONCLUSIONS: With the concerted efforts of family, school, society and natian, we as family physicians should make efforts to delay and prevent adolescent's smoking, which is a gateway to drug abuse and deviated behaviors, and to increase people's recognition of health risks caused by smoking, and to provide proper program for adolescents to stop smoking.

OBJECTIVES: This study is designed to discuss the pros and cons related to the 'separation of drug prescription and dispensation' system when 5 years have passed by since the introduction of this system. METHODS: The 592 psychiatrists from 1,107 working places took part in nationwide survey by mail or E-mail from June to September, 2005. The response rate was 23.8%, most of respondents came from private clinics. RESULTS: The average age of psychiatrist was 44.6 years old, ranging from 25 to 75, most of them was predominantly male. The main results were as followings: 1) The ratio of psychiatric prescription out of hospital based on out-patients departments was the lowest in clinics, following by hospitals, general hospitals and university hospitals by order. 2) The main reasons of customer's preference for out of hospital prescription were economic advantage and self-awareness of prescription. As for the disliking for it, the most complaints were the anxiety about disclosure of psychiatric treatment, in convenience for delay and concern about drug change. CONCLUSION: Five years didn't seem to give a change on how the psychiatrists perceive the 'separation of drug prescription and dispensation' system at all. The confidentiality and human right issues on the part of psychiatric patients should never be ignored in order to manage this system successfully.

PURPOSE: Dexamethasone is a well-known treatment for preterm infants with bronchopulmonary dysplasia. However, serious side effects have been identified, including hypertension, and cardiac hypertrophy. This study was undertaken to examine whether dexamethasone induced cardiac hypertrophy in preterm infants with bronchopulmonary dysplasia. METHODS: We retrospectively reviewed 12 infants with bronchopulmonary dysplasia treated with dexamethasone at Korea University Hospital from August 1995 to February 1999. Serial two-dimensional and M-mode echocardiographic measurements were taken before treatment and at 1,2,3,4,5 weeks after the start of dexamethasone therapy. RESULTS: Patients receiving dexamethasone had a significantly increase in interventricular septal thickness and left ventricular posterior wall thickness. These effects were transient, reached their maximal degree by the third week of treatment, and approached pretreatment conditions by the fifth week of treatment. Heart rate was increased but statistically not significant. The fractional shortening, systolic and diastolic arterial pressure were transiently increased during dexamethasone therapy. CONCLUSION: We conclude that a transient myocardial hypertrophy is associated with dexamethasone therapy in infants with bronchopulmonary dysplasia. Follow up of careful echocardiac monitoring should be considered in infants with dexamethasone therapy.

Myocardial bridging is defined that short segments of coronary artery descend into the myocardium for a variable distance and each systolic contraction of these fibers can cause narrowing of the artery. Systolic narrow-ing may rarely be caused by connective tissue such as fibrous band. Myocardial ischemia, infarction and sudden death may be seen in some patients with myocardial bridging. Myocardial infarction in association with isolated myocardial bridges with systolic narrowing is uncommon. We report a case of Q wave myocardial infarction in a patient with angiographic systolic narrowing at the middle segment left anterior descending coronary artery which was caused by fibrous band.
