This study was performed to investigate the average anthropometric value of normal Korean men and women and to compare the preceding literatures. Additionally, average Korean profilogram was made to serve as a template for diagnosis of facial form. Eighty five Korean subjects(41 men, 44 women) aged between 21 to 26 were selected by members of the author's department on the basis of intact dentition and Class I occlusion without facial asymmetry. Frontal and lateral photographs were taken under standardized condition with digital camera. The image was magnified and adjusted according to the FH plane of cephalometric radiographs and digitized using personal computer. To compare the Western beauty, 25 esthetically pleasing female was selected to measure various angle and distance of the face. 1. It was possible to calculate the mean coordinate value of Korean normal samples which enables the direct visualization and comparison with the use of template. The method in this study was easy to applicate under the Microsoft Windows bases. 2. Maxillary vertical hypoplasia, upper and lower lip protrusion was characteristics of Korean norms and relatively narrow alar base distance, less conspicuous nasal projection was observed. As the vermilion exposure and upper lip length was more than western norm, chin looks shorter than western. To compare the Korean and Western esthetically pleasing profile, facial convexity and nose was less conspicuous in Korean women.

The purpose of this study is to evaluate the relationship of the factors which could be influenced by orthognathic surgery especillay SSRO. We measured the amounts of the maximum opening, lateral movements, maximum velocity and pattern of mandibular path during the opening and closing of mandible at the following times ; preoperative, 1 month after operation, 6 months after operation respectively using MKG. And the results were compared according to the categorized subgroups. Following results were obtained : 1. The change of the amounts of mandibular lateral movement and maximum opening velocity were statistically different between male and female (p<0.05), but the others were not. 2. According to the method of operation, there was no difference in the change of the mandibular movements between the group of SSRO and SSRO plus LeFort I osteotomy (p>0.05). 3. According to the amounts of mandibular movement, the recovery of left lateral movement of the group of 6~10mm was better than the other groups (p<0.05). 4. In the frontal pattern of the opening and closing of the mandible, the complex deflected type (F5), simple deflected type (F4), complex deviated type (F3), simple deviated type (F2), straight type (F1) were obtained in order at the time of preoperative, simple deflected type, simple deviated type, complex deviated type, straight type, complex deflected type in order at the time of 1 month after surgery, and the result at the time of 6 months after surgery was the same with that of the time of preoperative. In the sagittal pattern, non-coincident type (S2) was predominant at the time of preoperative, and coincident type (S1) was predominant at the time of 1 month after surgery. After 6 months, the result was also the same with that of the preoperative in sagittal pattern. 5. There was not a statistical difference in the change of the mandibular movement between group of presence of the preoperative TMJ symptoms and non-presence group (p>0.05). 6. There was not a statistical difference in the change of the mandibular movement between repositioning device applied group and non-applied group (p>0.05). 7. Sixty three percents of the patients who had preoperative TMJ symptoms were improved after surgery and preoperative TMJ symptoms were more improved after operation in the repositioning device non-applied group statistically (p<0.05).

To analyze the developmental changes in soma diameters of digastric motoneurons, wheat-germ agglutinin conjugated horseradish peroxidase (WGA-HRP) was injected into the digastric muscle and visualized the retrogradely HRP-labeled motoneurons through tungstate/tetramethylbenzidine (TMB) and following diaminobenzidine (DAB) reactions. The results obtained from Sprague-Dawley rats at postnatal days 1 (P1), 10 (P10) and 30 (P30) indicated as follows: firstly, soma diameters of digastric motoneurons showed unimodal distribution in all postnatal days examined; secondly, the period of P1 to P10 (period 1) showed about 2 times faster growth rate than that of P10 to P30 (period 2); thirdly, the smallest soma examined in each postnatal day exhibited slower growth rate with that of the largest one (increase ratio in soma diameters from P1 to P30, smallest vs. largest =1.62 : 1.93); Finally, relative growth rates a day showed again that period 1 had faster growth rate than that of period 2. Consequently, developmental changes in soma diameters of digastric motoneurons resulted in very different growth rates between both periods. This implies that the growth of the soma is almost completing within P10 and thereafter growing slowly. The period 1 and 2 are corresponding to sucking and sucking/masticatory period, respectively. Therefore present study providing morphological changes in soma diameters of digastric motoneurons suggests that both periods and their different growth rates of the motoneurons in each period may closely be related with each other.

Patient-controlled analgesia (PCA) has been widely used for postoperative pain control in medical surgery parts. Conventional intramuscular analgesia (IMA) is also effective in postoperative pain control, but it has some disadvantages that depend on patients'perception of pain and the anxiety that they endure caused by the delay of the injection time. This study was conducted to assess the efficacy and postoperative outcomes of intravenous PCA compared to IMA injections in 36 patients (BSSRO). Three factors were compared: amount of pain in PCA and IMA group ; amount of pain according to the sex in PCA and IMA group and the amount of pain according to the analgesia use. Results of this study did not demonstrate a statistically significant difference in any of these, using a p value of 0.05. The results of this study were as follows: 1. There was no statistically significant difference in VAS pain score between IMA group and PCA group. 2. There was no statistically significant difference according to the sex. 3. There was no statistically significant difference according to the amount of PCA. The history of PCA is about 30 years and many literatures have reported about its effects, complications, methods, advantages and disadvantages. So, this study has some limitations of small sample size to conclude the effects of PCA. But when the decision about the method for postoperative pain control has to be made, it should be made based on patient or physician preference and cost factors rather than on the trend.

BACKGROUND: Diastolic function can be assessed by Doppler-derived left ventricular(LV) filling patterns. E/A ratio<1 and prolongation of isovolumic relaxation time(IVRT) are diagnostic of impaired relaxation of left ventricle during diastole. In early stage of acute myocardial infarction, myocardial stiffness can normalize the E/A ratio and mask the Doppler indexes of abnormal relaxation in patients with acute myocardial infarction. METHODS: LV filling patterns were studied with Doppler echocardiography in 10 healthy subjects and 27 patients with recent acute myocardial infarction. Cardiac catherterization was performed in the 11+/-2 days after onset of acute myocardial infarction and left ventricular end-diastolic pressure(LVEDP) and myocardial stiffiness index(MSI) were studied. RESULTS: In patients with acute myocardial infarction, IVRT was significantly prolonged ; E/A ratio and deceleration time were decreased but not significantly different from those of normal subjects. In the patient's group of E/A>1,IVRT and atrial filling fraction(AFF) were significantly shortened, and LVEDP was significantly increased, compared to those of the patient's group of E/A<1. But ejection fraction was similar in both groups. In the patients with acute myocardial infarction, E/A ratio and LVEDP showed good correlation(r=0.64, p<0.05). MSI was increased in the patient's group of E/A>1 and also was well correlated with LVEDP(r=0.8, p<0.05). CONCLUSIONS: Thus we conclude that normal of increased E/A ratio in recent acute myocardial infarction may reflect increased LVEDP due to increased myocardial stiffness.

PURPOSE: Fournier's gangrene is a potentially fatal infectious necrotizing fasciitis of the scrotum, penis, and perineal region. If not recognized early, this process will extend along the fascia plane to the lower abdominal and back regions, causing severe morbidity and even mortality. The aims of this study were to investigate the clinical characteristics and to evaluate the outcome of our experience with 16 cases of Fournier's gangrene. METHODS: Clinical data from 16 patients with the diagnosis of Fournier's gangrene, who were treated at Gil Medical Center from January 1995 until October 2001, were analyzed retrospectively. RESULTS: The patients consisted of 14 men and 2 women, with an average age of 62 years. The potential ports of entry for the causative bacteria included the anorectum (75.0%), the urinary tract (18.8%), and the skin (6.3%). Predisposing factors included diabetes mellitus (62.5%), alcoholism (6.3%), steroid use (6.3%), malignancy (6.3%), and ulcerative colitis (6.3%). Escherichia coli and Staphylococcus aureus were most commonly identified in bacterial cultures. All patients were treated with a broad spectrum antibiotics and serial surgical debridement. Twelve patients had fecal diversions, and five patients had urinary diversions. Three patients underwent orchiectomies. One patient (6.3%) died due to sepsis. CONCLUSIONS: The management of this infectious entity should be aggressive with early recognition. Patients with Fournier's gangrene need prompt extirpation of all nonviable tissue and a cystostomy or a colostomy when necessary. A broad-spectrum antimicrobial regimen and aggressive debridement are mandatory.

A 44-year-old woman who comlpained of dizziness and generalized weakness was admitted. The hemoglobin was 6.6g/dL, hematocrit 25.5%, and serum ferritin 2.14 ng/mL Stool occult blood was positive and microcytic hypochromic anemia was found on periyheral blood smear. Gastroscopic examination showed about 2 x 1 cm sized hemispherical sebmucosal tumor on antrum. The patient underwent operatioh for confirmatory diagnosis and treatment. The final pathologic diagnosis of the resected lesion was hemangioma of stomach. Cavernous hemangioma of stomach is a rare disease.Mostly, it has a benign course clinically, but early diagnosis is important because massive hemorrhage and anemia by chronic blood loss can occur. We report a case of hemangioma of stomach with review of literature.

The piercing is increasing in western culture, and has also become gradually popular among Korean teenagers recently However, the accident happens sometimes such as loss of a bar into the tongue or mouth floor during the procedure. Because of the rare cases, few treatment of choices can be made when a bar is lost inside the mouth floor. In this case, the bar was removed under fluoroscope, without giving significant damage to the adjacent structure. 18 years old female patient visited the emergency room in our hospital. She attempted to pierce her tongue herself and could not find the bar which was lost in the mouth floor. The radiographs revealed that the needle was somewhere inside the mouth floor, but if incision were to be made it would be too deep to find the bar. The bar was reomoved through fluoroscope easily. Primary closure was done by 5-0 Vicryl and stitch-off was done 1 week later. The patient didn't have any speech problems and complications.
