The reduction of nasal bone fracture has been done by a simple procedure. The nasal bone fracture was not a serious problem and patients are usually treated as outpatients. However it is causing increased demand for medical services far cosmetic reasons. We studied the nasal bone fracture by retrospective analysis, it comprising 606 patients with nasal bone fractures in various accidents and treated of Chonnam University Hospital from March 1995 to February 1998. We reviewed and analyzed the medical records and facial bone CT scans of 606 patients. The following results were obtained. 1. The prevalent age group was in the third decade, the most common cause was traffic accidents, while nasal swelling, tenderness, nasal deviation and crepitation were examined 2. The classification of nasal bone fracture was done by facial bone CT. Class 1: Nasal tip depressed fracture(16%) Class 2: Displaced nasal bone fracture without depression(30%) Class 3: Displaces nasal bone fracture with depression(12%) Class 4: Comminuted nasal bone fracture (10%) Class 5: Simple fracture of nasal bone and frontal process of maxilla(14%) Class 6: Comminuted fracture of nasal bone and frontal process of maxilla(11%) Class 7: Nasal bone fracture without displacement(9%) .

It is well-known that the infection of bone and joints could produce the shortening by destroying the articuiar cartilage and growth plate, or the lengthening hy increased hlood circulation to the epiphyseal and metaphyseal regions of long bone. Since 1985, we have treated total l7 cases of children s pyogenic or tuberculous children s knee with early arthrotomy and continuous irrigation etc. and followed their long hone growth for average 53 months after surgical intervention. Five patients (group I ) were early treated within 2 weeks and twelve patients(group 3 ) were delayed to treat their knees for more than 2 weeks of symptom development. Total 11 patients out of 17 cases(64.7%) (2 cases of group 1 pyogenic arthritis, and 1 case of group l and 8 cases of group II tuberculous arthritis) revealed growth acceleration. Femoral lengthening was much more greater than that of tibial growth, and the size of patella, distal femoral and proximal tibial epiphysis which were measured by computerized digitizer were also significantly larger than that of opposite knee. The total limb length was increased hy average 7mm in 6 months, l4mm in 1 year and 3mm in 2 years after operation. These results suggest the pyogenic and tuberculous arthritis in children s knee should he treated as early as possible after symptoms developed, and followed them to trace their limh inequality for at least 2 years after surgery. That means the early arthrotomy for tuberculous knee or even in pyogenic arthritis can preserve normal articular cartilage and can also prevent the early epiphyseal closure hy infection. and can get the limh lengthening by increased blood circulation around the knee joint.

BACKGROUND: Bupivacaine is a amide type local anesthetic agent, widely used for its excellent quality of analgesia and long duration of action. But unintended intravenous injection causes severe complication such as convulsion and cardiovascular collapse, which is known for its difficulty in resuscitation. With all the study, the exact mechanism is still unclear and there are much debate on the method of resuscitation. METHOD: We studied the effect of clonidine pretreatment on bupivacaine-induced cardiac toxicity and resuscitation in anesthetized dog. Twelve dogs were divided into two groups. : saline pretreatment group (control, N=6) and clonidine pretreatment group (clonidine group, N=6). The dogs were anesthetized with N2O-O2-enflurane and vecuronium. Thoracotomy was done in 4th or 5th intercostal space for open cardiac massage. After confirming stability of vital signs, we administered clonidine (10 mcg/kg) or saline, and then administered bupivacaine with the rate of 2 mg/kg/min. When the electeocardiogram showed asystole, 20 mcg/kg of epinephrine was administered via central venous line and open cardiac massage with the rate of 120 beat/min. was performed. We observed electrocardiogram (lead II), arterial blood pressure, heart rate, dose of infused bupivacaine to be required for QRS widening and arrest, required time and administered dose of epinephrine for resuscitation. RESULTS: Clonidine group showed significant decrease of heart rate after pretreatment (p<0.05). There was no significant difference in required dose for QRS widening between two groups. The dose administered for inducing arrest was less in clonidine group than control group (p<0.05). The time required for resuscitation was shorter in clonidine group than control group (p<0.05). The total dose of epinephrine required for resuscitation was less in clonidine group than control group (p<0.05). The blood concentration of catecholamine did not showed significant difference during the whole course of experiment. CONCLUSIONS: Above results demonstrated that clonidine, a central nervous system-mediated sympatholytic agent, facilitated cardiac arrest when bupivacaine was infused intravenously and cardiac rescucitation.

BACKGROUND: Despite improvement of mortality in acute myocardial infarcrtion, high mortality rate associated with cardiogenic shock remains essentially unchanged. We have reviewed our result of coronary intervention in 15 patients and found relative survival advantage. METHODS: Between Sep. 1992 and Aug. 1995, 15 consecutive patients(M. 10, F. 5) with cardiogenic shock in acute myocardial infarction were treated with coronary intervention using ballon PTCA. IABP was inserted in all patients prior to PTCA. RESULTS: 1) Most commonly found infarct related artery was left anterior descending artery(11) followed by right coronary artery(3) and left main coronary artery(1). 2) Successful reperfusion rate was 86.7%(13/15), and in-hospital mortality rate was 26.7%(4/15). 3) In-hospital mortality was higher in elderly patients compared with less than 70yaer old patients(0%(0/11)vs. 75.0%(3/4)(P < 0.05). 4) Mortality rate was lower in single vessel disease than multivessel disease(11.1%(1/9) vs. 50%(3/6) p<0.05). CONCLUSION: Although this study is uncontrolled, the date suggest that urgent coronary intervention for improving coronary perfusion may reduce mortality of acute myocardial infarction complicated by cardiogenic shock, particularly with single vessel disease and young age group.

The combination of an intradermal nevus with epidermal cyst or other adnexal tumors has often been described since 1952. Most of these reports have involved the coexistence of common epidermal cysts and melanocytic nevi. Herein, we report a 21-year-old Korean male, who initially presented to our department with a rapidly enlarging preexisting nevus on his back. The mass was surgically excised and histopathologically showed intradermal nevus combined with epidermal cyst.

Objectives : A diverse range of adverse effects has been linked to the application of antidepressants for the treatment of depressive disorder. Recently, evidence has been emerging of the adverse metabolic effects of antidepressants. This study investigated the effects of antidepressants on plasma glucose and other factors in the fat and muscle tissue relating to metabolism. METHODS : Long-Evans-Tokushima-Ostuka (LETO) rats were used to evaluate the effects of different antidepressants. Amitriptyline, fluoxetine, and mirtazapine were administered to each of three subgroups for 4 weeks, between 11 and 15 weeks old, while a fourth subgroup was administered no antidepressant during the same period. Changes of weight and daily intake were monitored. Tissues and blood were collected at 15 weeks. RESULTS : The fluoxetine subgroup showed lower weight gain and lower food efficacy ratio than did the other subgroups. Blood glucose and other circulating factors showed no significant differences among groups, except for the leptin levels of the fluoxetine subgroup. However, the amitriptyline and mirtazapine subgroups showed similar patterns in the response of mRNA expression of peroxisome proliferator-activated receptors gamma cofactor-1 and uncoupling protein-1, 2, 3. CONCLUSION : These results could indicate possible differences in metabolic response based on the kind of antidepressant used.

OBJECTIVE: The purpose of this study was to evaluate the suicide ideation considering sociodemographic factor and degree of symptoms, subjective emotional state of the social phobia patients. METHODS: Study subjects consisted of 34 social phobia patients diagnosed with the criteria of DSM-IV. The authors evaluated the degree of symptomes, depression, hopelessness, disability. For the evaluation of suicide ideation, Beck Suicide Ideation Scale (SIS) was applied to the patients. Sociodemographic data and Clinical characterictics was analyzed by t test or Oneway ANOVA. We employed the correlation test for the evaluation of relationship between suicide ideation and self reported scale score. RESULTS: 1) Suicide ideation was higher in the young aged, unmarried patients, and past suicide attemptors. 2) In the correlation test, Suicide ideation was highly correlated with depression and hopelessness. 3) There were no significant correlations between suicide ideation and degree of symptomes. CONCLUSION: In this study. We concluded that the most powerful predictor of suicide ideation in social phobia is not the degree of symptomes itself but the depression and hopelessness.

Primary tumors of the heart are rare. Half of all cardiac tumors are myxoma of which 20% are located in the right atrium. Especially multiple myxomas in the cardiac chamber were rarely reported. Clinically, myxomas present with various manifestations due to obstruction to blood flow, embolization,and constitutional changes. The association of pulmonary emboli and right atrial myxoma has been well documented but pulmonary emboli are more likely to be asymptomatic, misdiagnosed, or diagnosed late than peripherally-sited emboli. We report a case of multiple right atrial myxomas complicating pulmonary emboli in a 73-year-old man who had features of pulmonary embolism and was found to have multiple right atrial myxomas.

To study why the palmar capsular connections between radius and lunate remain intact in perilunate ligamentous injury of the wrist joint, and to compare the material properties of the short radiolunate, long radiolunate, and radioscaphoid region of the radioscaphocapitate ligaments (as the extrinsic ligaments) with those of the intrinsic ligaments of the previous papers, the anatomical and mechanical characteristics of those three palmar radiocarpal ligaments of twenty cadavers were measured and tested by a servo-hydraulic test machine. In spite of its small cross-sectional area (24% of short radiolunate ligament), the radioscaphoid ligament demonstrates a failure load of 58% and a stress of 260% of the short radiolunate ligament, and toughness similar to both the short and long radiolunate ligaments. This suggests that the radioscaphocapitate ligament may contribute as an initial constraint to perilunate injury. The failure load of the scapholunate ligament might be smaller than previously reported due to testing strain rate, which coupled with its short initial length may make it more vulnerable to injury at lower applied loads. The short radiolunate ligament, in spite of the largest width and cross-sectional area, has a failure load and toughness similar to the long radiolunate ligament. The material properties of short and long radiolunate ligaments may explain why the rest of the carpals persistently dislocate or fracture about lunate.
