BACKGROUND: The concentration of the blood including ACTH, catecholamine, serum prolactine, cortisol is increased due to responding on stress by carrying out endotracheal intubation upon the mutiple trauma patients who were taken to the emergency room. Diazepam is a kind of benzodiazepine pharmacon and common pharmacon used for stability of the patients, relief and pretreatment as a booster for the relaxation of skeletal muscle. This research aims to know how effectively medication of diazepam before endotracheal intubation helps to constrain the reaction on the part of cardiovascular system due to laryngoscopy and endotracheal intubation, and makes concentration of catecholamine in blood changed. METHODS: The subjects are consisted of the patient asked for endotracheal intubation instantly, suffering from caput trauma (GCS 8.0) among the multiple trauma patient, more than 20-year-old who were taken to the emergency room in Chosun university hospital from October 1, 1995 to September 30, 1996. They were decided into 2 classes, 30 people each class, and one (group I ) was carried out endotracheal intubation without injecting diazepam,0.3 mg/kg, and the other (group II) was done with the endotracheal intubation by injecting diazepam, 0.3mg/kg. Group I and group II were measured blood pressure and heart rate before intubation and at 1, 3, 5, 7 minute after endotracheal intubation, sampled arterial blood from femoral artery, and then compared and analyzed. All of the data were recorded by mean, standard deviation, and percentage and repeated measures ANOVA test was used for the statistical test and the data was regarded as statistically significant when p value is below 0.05. RESULTS: 1) They were no significant differences statistically between 2 groups in the distribution of the age, weight, sex of the patients. 2) The changes in the systolic blood pressure had no statistical significance in the comparison between group I and group II, but diastolic blood pressure and the change of heart rate had statistical significance because p value was shown below 0.05. 3) Norepinephrine of blood was significantly lower in group II than group I. 4) Epinephrine of blood was significantly lower in group II than group I. CONCLUSION: It was shown that medication of diazepam before endotracheal intubation made stability of the patients and it changed significantly the reaction on the part of cardiovascular system from stress caused by laryngoscopy and endotracheal intubation. So it will be a good thing to inject diazepam for pretreatment to bring relief of the patients and cardiovascular stability before endotracheal intubation.

Six thumb reconstructions and one index reconstruction were performed by use of the wrap-around technique. All successful digital reconstructions were reviewed at an average of 37 months after surgery. There were complications related to the digits in three patients ; these included pin site infection (1), malrotation (1), and nail deformity (1). But we considered that function and cosmesis were excellent with a 100% viability rate. All patients regained protective sensation and sttained two-point discrimination (average 10mm). The wrap-around technique represents an esthetically and functionally excellent procedure of digit reconstruction for amputation at the level of metacarpo-phalangeal joint or distal to it.

Thirty one free vascularized fibula bone grafts were performed for treatment of osteonecrosis of the femoral head in 26 patients, 24 men and 2 women aged from 16 to 48(mean:32 years). Twenty one patients had unilateral disease. Five patients had bilateral disease underwent staged bilateral free vascularized fibula grafts three months apart. Associated etiological factors included alcohol(9 patients), steroid(7 patients), and trauma(one patient). The condition was considered idiopathic in the remaining 9 patients. Radiologic staging by Ficat included stage 1 in one hip, stage II in 15 hips, stage III in 14 hips, and stage IV in one hip. A skin island flap was used for monitoring purpose for the grafted fibula. One monitoring, flap was necrotized due to vascular occlusion but the fibula bone graft was left in place to use as a nonvascularized bone graft. Average follow-up period was 21 months in 31 hips. Pain was relieved in 28 hips(93.3 percent) and aggravated in 2 hips(6.7 per cent). On radiographic evaluation, 26 hips(86.7 per cent) demonstrated excellent preservation of the femoral head contour. Progressive collapse of the femoral head (greater than 1-2 mm) occurred in 2 hips, i mm depression in one hip with stage III and 2 mm collapse in one hip with stage IV. In conclusion, the free vascularized fibula bone graft is an excellent treatment modality for preserving the femoral head and relieving symptoms in cases of the osteonecrosis of the femoral head.

The number of cancers in the head and neck areas has been increasing due to the increasing life span of the patients and a free flap is a common procedure to reconstruct defect in the head and neck area. From March 1990 to February 1998, 105 patients underwent 110 free flap operations after head and neck cancer ablation and they were reviewed retrospectively. Among 110 free flaps, 93 are forearm flaps, 6 jejunal flaps, 5 vascularized fibular osteocutaneous flaps, 2 lateral arm flaps, 2 rectus abdominis myocutaneous flaps and 1 latissimus dorsi muscle flap and 1 latissimus dorsi myocutaneous flap. Sixty-five radial forearm flaps and 4 ulnar forearm flaps were utilized in patched type and 24 radial forearm flaps in tubed type mainly for the reconstruction of intraoral and hypopharyngeal defects. Sis jejunal flaps were utilized for the esophageal reconstruction and 5 vascularized fibular osteocutaneous flaps for the mandibular reconstruction. The remaining flaps were for the reconstruction of other areas of head and neck.Overall survival rate of the flap was 95.5%. Immediate complications were fistula formation(3 cases), total flap loss (4 cases) or partial flap loss(3 cases) and donor site problems(10 cases). Superior thyrodial artery was the most commonly used recipient artery(89 cases) which was followed by facial artery, lingual artery and transverse cervical artery. Size discrepancy was not remarkable between the donor and recipient arteries. However, there was usually a marked size discrepancy between donor and recipient veins. More than two venous anastomoses were performed to increase the success rate of the flap surgery. An average follow-up period was 38 months ranging from 3 months to 6 years. There was no patient who died during or right after the operations, but 23 patients died due to recurrence of tumors or underlying heart disease during the follow-up period. Remaining patients lived well excluding 6 late postoperative complications such as 4 cases of esophageal stenosis and 2 cases of osteoradionecrosis. We conclude that free flap reconstruction after head and neck cancer ablation improves the quality of life and minimizes the loss of function.

Drowning is the second most common cause of accidental death of children in Korea. But the study of near-drowning is very rare in Korea. The purpose of our study is to determine the factors that may influence survival on the basis of submersion time, consciousness state upon admission to hospital, the kinds of water, laboratory findings and neurological outcomes. The survey was performed by a retrospective cohort study on 28 near drowning victims of less than 15 years of age who were admitted to the emergency room in the Chosun University Hospital between May 1988 & May 1997. The results were as follows 1) Sex distribution was 22 males and 6 females. 2) Submersion time was (5 minutes in 9 cases, 5-9 minutes in 6 cases,10-14 minutes in 5 cases,15-19 minutes in 3 cases, > or =20 minutes in 5 cases. 3) Comatose patients upon arrival were 6/7 cases in the death group(86%) and 2/21 cases in the improved group(10%). they had unfavorable outcomes(P<0.05). 4) The first pH value was mean 7.02)0.12 in the death group and mean 7.31 +/-0.13 in the improved group. there was a statistically significant difference between the death and the improved group(P<0.05). 5) The patients who had increased blood glucose concentration were all 7 cases in the death group and 12/22 cases in the improved group(54%). The mean blood glucose concentration was mean 424.7235.6mg/dl in the death group and mean 140.182.7mg/dl in the improved group. There was a statistically significant difference between the death and the improved group(P<0.05). 6) The patients who had pulmonary edema upon arrival were all 7 cases in the death group and 1/21 cases in the improved group(18%). They had unfavorable outcomes(P<0.05). 7) The patients who had been submerged more than 15 minutes were all 7 cases in the death group and 6/21 cases in the improved group(5%). They had unfavorable outcomes(P<0.05). We conclude that pediatric victims of near-drowning can be assigned to high or low likelihoods of unfavorable outcomes with the use of five variables, comatose mentation upon arrival, decreased initial blood pH, increased initial blood glucose concentration, pulmonary edema, and maximum submersion time estimated longer than fifteen minutes. This prediction rule may be useful if it can be validated in another cohort.

The following conclusions were obtained from the non-reconstructed and reconstructed subtraction images of the standard intraoral radiographs which were taken with paralleing technique with Rinn XCP only and with occlusal bite registration for geometric standardization using bilateral mandibular premolar and molar regions of two dry humad skulls. 1. The SD of the overall subtraction images of the premolars and molars of the non-reconstructed, tnat is, the manual superimposition showed statistically significant difference between the non-registered and registered groups. 2. In non-reconstructed and non-registered cases, the quality of the subtraction images were improved when superimposition was focally done and this was more evident in areas where the radiographic imaged tend to be distorted due to anatomic readons. 3. In non-restructed and registered cases, the subtraction images were consistent regardless of the anatomic site or the focus superimposition. This means that the geometric standardization with only occlusal bite registration could produce serial radiographs which is suitable for subtraction. 4. The SD of the overall subtraction images of the premolars and molars of the reconstructed, that is, the automatic superimposition showed statistically insignificant difference between the non-registered and registered groups. This means that using reconstruction, subtraction radiography is possible without occlusal bite registration. 5. In reconstructed and non-registered cases, compatible quality of the subtraction images were obtained regardless of the anatomic site or area of the corresponding points. 6. In reconstructed and registered cases, best subtraction images whose quality showed sensitivity to the areas of corresponding points were obtained.

The authors examined the condylar position and shape of condylar process from the transcranial radiographs and polytomographs of the 130 temporomandibular joints of 65 patients who complained symptoms of temporomandibular disorder and the followings were obtained ; 1. The age and sex distribution of the 65 patients showed peak incidence in 2nd decade (27.7%) followed by 3rd (18.5%) and 4th decade (18.5%) and female predominance (87.7%). 2. In polytomography 64 joints (49.2%) showed consistent condylar position from lateral to medial and 39 joints (30.0%) of them showed agreement with those of transcranial radiographs. Among the 66 joints (50.8%) which showed changes in condylar position, 48 joints (36.9%) showed agreement with lateral and central tomographic and transcranial radiographic position. 41 joints (31.5%) showed disagreement in condylar position between the polytomographic and transcranial radiographic images. 3. When the condylar position was classified as anterior, central and posterior, the posterior position was the most frequent position, that is , 42.3% of the transcranial radiography and 42.3%, 49.2% and 38.5% of the lateral, central and medial polytomographic radiographs. 4. In polytomography 84 joints (64.6%) showed consistent condylar shape from lateral to medial and 74 joints (56.9%) of them showed agreement with those of transcranial radiographs. Among the 46 joints (35.4%) which showed changes in condylar shape, 40 joints (30.1%) showed agreement with lateral and central tomographic and transcranial radiographic shape. 41 joints (31.5%) showed disagreement in condylar shape between the polytomographic and transcranial radiographic images.

To know the prevalence of the diabetes mellitus and associated diseases, we analyzed the date of the 3,088 subjects who were examined with the Computed Automated Medi-Screening Test System which consisted of 65 parameters including blood glucose determination fasting and one hour after 100 g of oral glucose load. We grouped the subjects by the modified criteria of National Diabetic Data Group. Followings are the results of the various analysis: 1. The prevalence of diabetes mellitus and impaired glucose tolerance in 2.27% and 18.26% respectively. 2. The prevalence of diabetes mellitus is 2.63% in male and 1.66% in female. There is no statistically significant difference between male and female. 3. There in tendency of increasing prevalence of diabetes mellitus as the age increases. From second to eighth decade, the prevalence of diabetes mellitus increases as 0.0, 0.45, 0.67, 2.28, 3.47, 5.36, 10.00% respectively. 4. There is no statistically significant difference of prevalence of obesity between normal and diabetes: that is, 18.03%, 22.86% respectively (P≥0.1). 5. There is no statistically significant difference of prevalence of impaired glucose tolerance and diabetes between non-obese and obses group (P≥0.1). 6. There is statistically significant increases of frequency of proteinuria, azotemia, hypertension as the glucose tolerance decreases (P≤0.05).

From 1989 to 1996, push back palatoplasty, 2-flap palatoplasty and Furlow's palatoplasty were the main procedures of cleft palate repair in our institute. To compare the maxillary growth state of patients in each palatoplasty group, evaluation of dental occlusion and cephalometric analysis were performed in total 50 patients. The results were as follows: 1. Normal control group was composed of 17 children who didn't have cleft lip or cleft palate. Mean values of cephalometric data in the normal control group were 6.19 cm in SN length, 1.17cm in ONA length, 7.29cm in effective maxillary length 53.88degree in SNO angle, and 82.41 degree in SNA angle. 2. Fourteen patients who underwent push-back palatoplasty showed anterior crossbite in all cases. SNO angle and SNA angle were significantly decreased compared to the normal control group, which indicated significant impairment of maxillary growth. 3. In seventeen patients who underwent 2-flap palatoplasty, 7 patients showed anterior crossbite. Cephalometric parameters showed no significant difference compared to the normal control group. 4. Nineteen patients underwent Furlow's palatoplasty. In this group, 3 patients had anterior crossbite. Cephalometric parameters showed no significant difference compared to the normal control group. Although this report was based on data acquired from patients before the age of complete maxillary growth, our results suggested that each palatoplasty would have a different influence on maxillary growth.
