Korean Journal of Orthodontics 1978;8(1):19-26
This study was undertaken to establish the cephalometric standards of Hellman dental age III A group of Korean on the roentgenocephalometry. The subjects consisted of 26 males and 29 females with the normal occlusion and acceptable profile. The following conclusions were obtained; 1) The tables of mean and standard deviation were made from the measurements of both male and female. 2) All linear measurements in male were greater than those in female. 3) Mandibular growth rate of female was greater than that of male. 4) Comparision of the children in Hellman dental age III A with those in the late primary dentition indicated the tendency of facial vertical growth.

We experienced 5 cases of acute rubella encephalitis, a serious complication of rubella. The patients presented with convulsions and a deteriorated mental state, both of which occurred with a vanishing maculopapular rash and a low grade fever. The cerebrospinal fluid analysis showed pleocytosis and increased protein and normal glucose levels. We diagnosed the rubella encephalitis by detection of IgM in the serum. Rubella encephalitis is known to be a serious complication of rubella, and with poor prognosis. The mortality rate may reached as high 20%. Our cases recovered without any sequelae.

PURPOSE: To evaluate the incidence,. degree, and clinical significance of non-obstructive intrahepatic bile duct di'latation encountered on follow up CT after gastrectomy for gastric carcinoma. MATERIALS AND METHODS: We retrospectively analyzed follow-up abdominal CT of 65 patients who had undergone gastrectomy with truncal vagotomy and subtotal gastrectomy for gastric carcinoma. We classified those patients who showed intrahepatic duct dilatation into non-obstructive or obstructive groups depending on the presence or absence of the lesions obstructing the duct. We also evaluated the incidence, degree and pattern, and appearance time of non-obstructive type of duct dilatation. RESULTS: Non-obstructive and obstructive biliary dilatations were present in 8 cases(12.3%) and 9 cases(13. 8%), respectively. The degree of non-obstructive group was mild in 6 cases(75%) and moderate in 2 cases (25%) who had taken cholecystectomy during the follow up period, and patterns were proportional dilatation of the central and peripheral intrahepatic ducts. It appeared on follow up CT obtained 6 to 12 months after operation in 7 cases and 3.5 months in one case. No statistical significance was noted between the type of surgery and the incidence of non-obstructive dilatation(p>0.05). CONCLUSION: Mild dilatation of the central intrahepatic ducts without evidence of mechanical biliary obstruction can be seen on follow-up CT obtained more than 6 months after gastrectomy for gastric carcinoma, and the incidence is about 12%. We think that this finding is non-obstructive and clinical evaluation is unnecessary.

PURPOSE: To demonstrate the usefulness of diffusion-weighted MR imaging(DWI) in patients with small acuteinfarction by comparing it with fast spin-echo T2-weighted MR imaging(FSE T2WI). MATERIAL AND METHOD: Weretrospectively analyzed the results of FSE T2WI in 26 consecutive patients who on DWI showed small discretehyperintensities of less than 1.5cm and whose final clinical diagnosis, within one week of clinical attack, wasacute inforction. Lacunar infarcts accounted for 24 cases and 2 small cortical infarcts for two. The onset ofsymptoms occurred within 12 hours (hyperacute stage) in two patients, within 24 hours in seven, within 3 days innine, and within one week in eight. Infarcts as seen on FSE T2WI were categorized as follows : (-) for cases ofimpossible localization with non-visualization ; (+/-) for cases of equivocal localization with faint visualizationand/or poor differentiation from combined chronic infarcts and chronic ischemic changes, or from subarachnoid CSFin cases of cortical infarction ; and (+) for cases of adequate localization with clear visualization andmoderately good differentiation from the associated brain changes, or from subarachnoid CSF in cases of corticalinfarction. These infarcts were analyzed according to the time of onset of symptoms. RESULT: For the localizationof small acute infarctions, DWI was markedly superior to the category(-), moderately superior to the category(+/-).With regard to the onset of symptoms, DWI was markedly or moderately superior to FSE T2WI in 2/2 (100%) ofhyperacute stage diagnosed within 12 hour of clinical attack, in 4/7(57%) diagnosed within 24 hours, in 5/9 (56%)diagnosed within 3 days, and in 1/8 (13%) diagnosed within 1 week(p<0.05). In 12/26 cases(46%), small acuteinfarcts were localized by DWI better than by FSE T2WI. CONCLUSION: Because the signal was unchanged or itsintensity was poor, small infarcts at the acute stage were frequently difficult to localize by FSE T2WI. Inaddition, differentiation of these from combined chronic infarcts and chronic ischemic change was poor. DWI canlocalize small acute infarcts even when the results of FSE T2WI are negative or inconclusive.

Generally, absolute alcohol embolization has been commonly used for treatment of arteriovenous malformation (AVM) because complete surgical extirpation of AVM can be an extremely hazardous and difficult. Even if absolute alcohol is safe embolic agent, it can result in pain, pulmonary hypertension, pulmonary embolism and post-embolization syndrome such as nausea, vomiting, hemolysis and myoglobinuria. So, general anesthesia is needed for alcohol embolization. In this case, anesthesia was induced with intravenous (IV) propofol 110 mg and succinylcholine 60 mg and maintained with propofol and vecuronium. The pulmonary artery pressure was monitored with a Swan-Ganz catheter. After alcohol injectons, systolic pulmonary artery pressure was increased, ranging 35-40 mmHg. And cola-colored urine was noticed. For treatment of pulmonary hypertension, nitroglycerine was given IV. The IV fluid rate was increased and furocemide was given IV to increase the urine output. After general anesthesia, the patient was awake but appeared to be alcohol-intoxicated. Blood alcohol level was 42 mg/dl. Urinalysis showed large amounts of myoglobin, hemoglobin and albumin. So, anesthesiologists have to keep in mind of such complications when absolute alcohol embolization is done.

BACKGROUND: The aims of this national survey were to determine the views of Korean people regarding the specialty of anesthesiology and the role of anesthesiologists and to consider the ways in which individual anesthesiologists and the Korean Society of Anesthesiologists inform the public. METHODS: This off-line national survey was conducted by a professional research organization to obtain exact and reliable data. The questionnaire included structured questions to identify perceptions of the specialty of anesthesiology and the role of anesthesiologists inside and outside the operating room, people's desire for explanation of anesthesia by anesthesiologists, and their opinion about the best way to raise awareness about anesthesia and anesthesiologists. RESULTS: Of the respondents, 25.2% did not know that anesthesiologists are in charge of anesthesia during surgery. Furthermore, even respondents who knew that had very little knowledge of anesthesiologists' actual roles inside and outside the operating room. Respondents wanted their anesthesiologist to inform them about their anesthesia. CONCLUSIONS: The public's awareness regarding the role of anesthesiologists seems to be inadequate. To improve this awareness, in hospitals, each anesthesiologist should provide patients with more exact and detailed information. Simultaneously, the National Society of Anesthesiology should provide systematic information reflecting the public's thoughts.

PURPOSE: To compare the results of two different surgical methods (translation vs rod derotation) in a correction of double thoracic adolescent idiopathic scoliosis (AIS) using pedicle screw instrumentation. MATERIALS AND METHODS: Forty-seven patients with double thoracic AIS treated by pedicle screw instrumentation were reviewed retrospectively after a minimum follow-up of 2 years. The patients were divided into two groups; TR group (translation method, n=14) and RD group (rod derotation, n=33). There were no significant differences in the preoperative curve characteristics between the two groups. RESULTS: In the TR group, the preoperative upper thoracic curve of 37+/-4 degrees improved to 24+/-4 degrees (35% correction), and the lower thoracic curve of 52+/-9 degrees improved to 18+/-5 degrees (65% correction). In the RD group, the preoperative upper thoracic curve of 40+/-7 degrees improved to 19+/-7 degrees (51% correction), and the lower thoracic curve of 56+/-12 degrees was improved to 16+/-6 degrees (72% correction). The correction of the upper and lower thoracic curves was significantly better in the RD group (p<0.05). Thoracic sagittal kyphosis was corrected from 21 degrees to 24 degrees in the TR group and from 18 degrees to 26 degrees in the RD group. There was no significant difference in the spinal balance, shoulder height difference, T1 tilt and fusion extent. The operating time and the amount of blood loss was 231 minutes and 2050ml in the TR group and 263 minutes and 3217ml in the RD group, respectively (p<0.05). CONCLUSION: In correcting double thoracic AIS using pedicle screw instrumentation, the rod derotation method showed better correction for the upper and lower thoracic curves. The translation method showed the advantages of easier application, a shorter operation time and less blood loss.

PURPOSE: Polymorphonuclear leukocytes (PMNs) are the first line of cellular response for host defense during acute inflammation. The ability of PMNs to produce and release numerous pro-inflammatory cytokines is now estabilished and plays an important role in triggering and maintaining the inflammatory response. We studied the autocrine downregulation of this process by invesgating the potential production by human PMNs of the major anti-inflammatory cytokine, interleukine 10 (IL-10). METHODS: Human PMNs were isolated from the peripheral blood of health volunteers by using the modified boyum method. Human PMNs were incubated at 37 degrees Cwith and without formyl Met-Leu-Phe (fMLP) for 30 minute, 2 hours, 4 hours, and 20 hours. The level of IL-10 was determined in each of the cell-free supernatants by using the enzyme linked immunosorbent assay (ELISA) method. RESULTS: Non-stimulated PMNs generated 1.40 +/- 1.791pg/mL to 3.46 +/- 1.607 pg/mL of IL-10 over the time course. Stimulation with fMLP resulted in an increase in the constitutive PMN-derived IL-10 by 2.74 +/- 0.762 pg/mL, 1.27 +/- 0.262 pg/mL, 1.19 +/- 0.364 pg/mL, and 2.44 +/- 1.317 pg/mL at 30 min, 2 hr, 4 hr, and 20 hr after stimulation, respectively, but these increases were not statiscally significant. CONCLUSION: Human PMNs seem unable to induce release of the most potent anti-inflammatory cytokine, IL-10, and down-regulate inflammatory response due to the autocrine mechanism. This could partly account for the persistence of local inflammation, when PMNs are the main infiltrating cells.

OBJECTIVE: This study was performed to evaluate the overall survival and the change in treatment modalities in patients with uterine endometrial cancer in Korea. METHODS: From January 1990 to March 2005, medical records of 740 patients with endometrial cancer in nine hospitals were reviewed. The overall survival was determined supported by the death statistics of Korea National Statistical Office. RESULTS: The mean age of patients was 51.5 years (range: 21-82 years). The mean gravidity and parity were 3.3 and 2.1 (range: 0-18, 0-9), respectively. The most common stage, grade and histological type at diagnosis were FIGO stage I, grade 1 and endometrioid adenocarcinoma (76.5%, 56.4% and 87.2%), respectively. The main treatment modalities was surgery on stage I (59.8%), surgery-adjuvant radiotherapy on stage II (55.1%), surgery-adjuvant radiotherapy or surgery-adjuvant chemoradiation on stage III (38.3%) and surgery-adjuvant chemotherapy on stage IV (55.6%). The preferred treatment modality was surgery only on grade 1 (69.0%) and surgery-adjuvant radiotherapy on grade 2-3 (43.4% and 53.2%). Surgery had been the most common method of therapy before 1998 but its prevalence gradually decreased. As a result, surgery-adjuvant radiotherapy and surgery-adjuvant chemotherapy were most widely performed in 2004-2005 and surgery-adjuvant chemoradiation also increased more than a twofold. The overall 5 years survival rate (5YSR) for all 740 patients was 81.3%. The overall 5YSR of stage I was 89.0%. The overall 5YSR of grade 1, grade 2, grade 3 were 96.0%, 92.0%, 80.0%. Before 1998, the survival rate was 77.0%. Since then it increased to 83-88% and in 2000-2001 it increased to 88.0%, and it was the highest survival rate. CONCLUSION: The survival rate of endometrial cancer has been improving for the past 15 years and the method of treatment is also being changed currently. In order to improve the survival rate of endometrial cancer, a close investigation including genetic and environmental factors of the pathophysiology of endometrial cancer along with the epidemiology of risk factors, should be carried out.
