The geographical distribution of active physicians who graduated from medical schools before 1985 were studied. Those who had emigrated, hold non-medical jobs, are in the military service, or work as public health physicians and resident staff were excluded from the study. A total of 27,728 physicians were analyzed. Our studies have shown a relationship between the location of the medical schools from the which the physicians have graduated and the geographical regions in which they practice. A statistically significant number of physicians are working near the medical colleges from which they have graduated. That is, those who had graduated from medical schools located in the southern area of the country are presently working in the same region. This relationship was shown to be especially significant for older physicians and female doctors, who work around the area of the medical colleges from which they graduated.

Interleukin-6(IL-6) is a multifunctional cytokine, and deregulated IL-6 gene expression has been implicated as being involved in the pathogenesis of a number of diseaaes. So we measured the serum level of IL-6 to find a relationahip between uterine cervical cancer and serum IL-6 level. The serum levels of IL-6 were meesured m 54 patients adrnitted to the Severance hospital, from August, 1992 to February, 1993, of whom 27 patients were diagnosed as invasive cancer of cervix, 17 as CIN, and also utilizing 10 patiente diagnosed as uterine myoma as a control group for matched age and parity. The average serum level of IL-6 in invasive cancer, CIN, and uterine myoma were respectively 30.33pg/ml, 37.27pg/ml, and 12.45pg Jml. In 22% af cervical cancer patients (6 of 27), and 27% of CIN patients (4 of 17) studied blood levels of II-6 were detected whereas only 10% of uterine myoma (1 of 10) shorved the same result. However, the difference does not seem to be statistically significant, There was no statistically significant difference among any of the groups, and age and stage did not show any significant cmrelation, and the results need furt,ber investigations.

Amipaque is a water soluble, non-ionic myelographic contrast media, and owing to its high diagnostic accuracy and safety, its use is gradually increasing. The authors studied the complications after Amipaque lumbermyelography in 61 patients with low back pain during the period from Jan. 1981 to Nov. 1981 in Chung Ang University Hospital. The results were as follows; 1. Total complication rate was 52%(32 of 61) and there was nosexual difference in its occurrence. 2. In total, no difference in complication rate was found between head-up positioned group with a degree of 30degrees (group I) after procedure and head-up positioned group with a degree of 70degrees (group II) but female patients had more complication rate in group I than in group II (75% vs 50%).Headache was more common in group I and nausea was more common in group II. 3. Headache was most common complicaiton (44%) and there was no sexual difference in its occurrence. 4. No significant difference in complication rate was found between patients proved to have HBP and patients to have not. 5. Complications were less common in patients with punctured level of L4-5 than in patients with L2-3 or L3-4 level puncture.

The purpose of this randomized, prospective study was to compare the intubation time, hemodynamic effect and complication rates of orotracheal intubation performed by direct laryngoscopic or lighted stylet (lightwand) methods in the controlled settings of the operating room. After approval of clinical investigation committee and informed consent from patients, healthy ASA class 1 and 2 elective surgical patients were studied. On arrival to operating room, EKG, radial arterial cannulation to monitor blood pressure continously and neuromuscular monitoring device were applied to patients. Anesthesia was induced with fentanyl 3 ug/kg, thiopental 4 mg/kg and vecuronium 0.15 mg/kg to facilliate relaxation. Ventilation was controlled for 5 min by facemask with oxygen-isoflurane (1.2 vol%) or enflurane(1.7 vol%) before intubation. The patients were intubated randomly using either direct curved laryngoscope (DL, 37 patients) or lightwand (LW, 36 patients). The time to intubation (TTI) was recorded. The mean arterial pressure(MAP) and heart rate(HR) were recoreded every 30 sec after intubation for 5 min. The changes of MAP and HR after intubation were compared with pre-intubation value. After extubation, complications such as mucosal trauma and postoperative sore throat were recorded. The data were analyzed using either unpaired t-test or Chi-square analysis, where appropriate. There were no failed intuhation in either groups. There was no significant differences between the groups with respect to sex, age, weight, height, existence of nasogastric tube. The TTI was similar between groups(14.5+/-8.1 sec for LW, 16.8+/-9.5 sec for DL). There was no differences in incidence of trauma(19.4% for LW, 16.2% for DL) between groups. There were no statistically significant difference in the maximal increase in MAP(44% for LW, 55% for DL at 30 sec) and HR(25.6% for LW, 24.1% for DL at 30 sec) and during 5 min following intubation. In canclusion, even though the hemadynamic effect after intubation was not influenced by using LW, the results of this study indicate that the use of the LW is as useful, effective and safe method as using DL for oro-endotracheal intubation. Further study may prove that using the LW to be an effective alternative technique of intubation in patients with difficult airway.

OBJECTIVES: This study was designed to investigate the association between 5-HT 2A receptor gene promoter -1438A/G polymorphism and bipolar disorder in a Korean population. METHOD: 5-HT2A receptor gene promoter -1438A/G polymorphism were typed with Polymerase Chain Reaction in 120 patients with bipolar disorder and 120 normal controls. RESULT: The distributions of the genotype in the bipolar disorder with A/A, A/G, G/G were 14 (12%), 66(55%), 40(33%), and in the controls were 30(25%), 59(49%), and 31(26%). The allele frequencies of the bipolar disorders with A and G were 94(39.2%), 146(60.8%), and in the controls were 119(49.6), and 121(50.4), respectively. There were significant differences in genotype distributions and allele frequencies of -1438A/G between patients with bipolar disorder and normal controls. CONCLUSION: These results suggest that 5-HT2A receptor gene promoter -1438A/G polymorphism may be related to the development of bipolar disorder in a Korean population.

Sodium fusidate, obtained by fermentation of the fungus, Fusidium coccineum, has a steroid structure and shows a very high antitaphycoccal activity. The allergic potentirl of sodium fusidate is low and few cases of contact allergy to sodium fusidate have been reported. We present two cases of allergic contact dermatitis to Fucidin cintentione developed postoperative dressing of a skin biopsy and the other after laser treatment of a vascular nevi. The patch test results showed positive reaction to sodium fusidate in both cases.

Analysis and prediction of the care charges related to colorectal cancer in Korea are important for the allocation of medical resources and the establishment of medical policies because the incidence and the hospital charges for colorectal cancer are rapidly increasing. But the previous studies based on statistical analysis to predictthe hospital charges for patients did not show satisfactory results. Recently, data mining emerges as a new technique to extract knowledge from the huge and diverse medical data. Thus, we built models using data mining techniques to predict hospital charge for the patients. A total of 1,022 admission records with 154 variables of 492 patients were used to build prediction models who had been treated from 1999 to 2002 in the Kyung Hee University Hospital. We built an artificial neural network (ANN) model and a classification and regression tree (CART) model, and compared their prediction accuracy. Linear correlation coefficients were high in both models and the mean absolute errors were similar. But ANN models showed a better linear correlation than CART model (0.813 vs. 0.713 for the hospital charge paid by insurance and 0.746 vs. 0.720 for the hospital charge paid by patients). We suggest that ANN model has a better performance to predict charges of colorectal cancer patients.
