		                        			 Background:
		                        			Mechanical thrombectomy (MT) of ischemic stroke was recommended as a clinical guideline in 2015, and the indication for time was expanded in 2018 based on two clinical studies. We aimed to compare and analyze the prognosis of patients treated under the extended time indication before and after the introduction of advanced software. 
		                        		
		                        			Methods:
		                        			We obtained data from medical records between 2016 to 2020. From 2016 to 2017, patients who did not receive MT who visited the hospital within 24 hours from the last normal time (LNT) were classified as standard medical treatment (SMT) group. Among patients who underwent MT between 2019 and 2020, patients who visited the hospital between 6-24 hours from the LNT were classified into the extended MT (EMT) group. Good outcome was defined as 3-months modified rankin scale (mRS) ≤ 2, and a poor outcome as mRS ≥ 4. 
		                        		
		                        			Results:
		                        			From 2016 to 2017, 1,058 patients were hospitalized for ischemic stroke, of which 60 (5.7%) received MT, and 27 patients were classified into the SMT group. Among 1,019 patients between 2019 and 2020, 85 (8.3%) received MT, and 24 patients were in the EMT group. Among the SMT group, only 3 had a good prognosis, and 24 (88.9%) had a poor prognosis. However, in the EMT group, 10 (41.7%) had a good prognosis, and 9 (37.5%) had a poor prognosis. The SMT group had a 49.1 times higher risk of poor prognosis compared to the EMT group (P = 0.008). 
		                        		
		                        			Conclusion
		                        			The number of patients with ischemic stroke who receive MT has increased by using advanced imaging software. It was confirmed that patients treated based on the extended time indication also had a good prognosis.

		                        			Duodenal varices are a serious complication of portal hypertension. Bleeding from duodenal varices is rare, but when bleeding does occur, it is massive and can be fatal. Unfortunately, the optimal therapeutic modality for duodenal variceal bleeding is unclear. This paper presents a patient with duodenal variceal bleeding that was managed successfully using percutaneous trans-splenic variceal obliteration (PTVO). A 56-year-old man with a history of alcoholic cirrhosis presented with a 6-day history of melena. Emergency esophagogastroduodenoscopy revealed a large, bluish mass with a nipple sign in the second portion of the duodenum. Coil embolization of the duodenal varix was performed via a trans-splenic approach (i.e., PTVO). The patient no longer complained of melena after treatment. The duodenal varix was no longer visible at the follow-up esophagogastroduodenoscopy performed three months after PTVO. The use of PTVO might be a viable option for the treatment of duodenal variceal bleeding.

		                        			This nationwide, prospective cohort study evaluated pulmonary function and radiological sequelae according to infection severity in 73 survivors from the 2015 Middle East respiratory syndrome (MERS) outbreak in Korea. Patients with severe pneumonia in MERS-coronavirus infection had more impaired pulmonary function than those with no or mild pneumonia at the 1-year follow-up, which was compatible with the radiological sequelae. Severe pneumonia significantly impairs pulmonary function and makes long radiological sequelae in MERS.

		                        			PURPOSE: To compare the dose distribution between carotid sparing intensity modulated radiotherapy (IMRT) and opposed lateral field technique (LAFT), and to determine the effects of carotid sparing IMRT in early glottic cancer patients who have risk factors for atherosclerosis. MATERIALS AND METHODS: Ten early glottic cancer patients were treated with carotid sparing IMRT. For each patient, the conventional LAFT plan was developed for comparison. IMRT and LAFT plans were compared in terms of planning target volume (PTV) coverage, conformity index, homogeneity index, and the doses to planning organ at risk volume (PRV) for carotid arteries, spinal cord and pharyngeal constrictor muscle. RESULTS: Recurrence was not observed in any patients during the follow-up period. V95% for PTV showed no significant difference between IMRT and LAFT plans, while V100% was significantly higher in the IMRT plan (95.5% vs. 94.6%, p = 0.005). The homogeneity index (11.6%) and conformity index (1.4) in the IMRT plan were significantly better than those in the LAFT plans (8.5% and 5.1, respectively) (p = 0.005). The median V5Gy (90.0%), V25Gy (13.5%), and V50Gy (0%) for carotid artery PRV in the IMRT plan were significantly lower than those in the LAFT plan (99.1%, 89.0%, and 77.3%, respectively) (p = 0.005). CONCLUSION: Our study suggests that carotid sparing IMRT can significantly decrease the dose to carotid arteries compared to LAFT, and it would be considered for early glottic cancer patient with high risk of atherosclerosis.

		                        			Squamous cell carcinoma (SCC) of the lower lip is the most common malignant tumor, comprising 90% of all lip SCC. The typical picture of SCC of the lower lip is an ulcerated lesion with raised margins. Surgery is the treatment of choice for SCC of lower lip. After resection, reconstruction is important both aesthetically and functionally, because the lower lip is a prominent location in the face and it is where essential functions of the sphincter are carried out as in assisting mastication, swallowing, phonation, and expressing emotion. Depending on the location and size of the tumor, different types of flaps are used. We describe here a successful technique to reconstruct a large lower lip defect using a submental island flap and a mucosal flap for patients.

		                        			OBJECTIVE: The purpose of this study was to analyze the inclination, pertinence and influential factor in emergent cesarean section according to the assortment and analysis of the indication of emergent cesarean section. METHODS: The retrospective study was performed with the review of 360 emergent cesarean section cases from January 2003 to December 2003. RESULTS: The indication of cesarean section was followed by the order of progress failure (47.5%), previous cesarean section (19.2%), and fetal distress (15.8%). The improper operation of emergent cesarean section was done in fetal distress (28.1%), progress failure (8.6%), and induction failure (16.7%). The absence of acceleration with prolonged bradycardia was the most common (50.0%) type of fetal distress. The emergent cesarean section were done more commonly on Tuesday and Friday during weekdays and it was the peak time in a whole day of cesarean section from 11 o'clock to 12 o'clock and 16 o'clock to 17 o'clock. CONCLUSION: It was proved that twenty six (7.2%) cases of emergent cesarean section were done improperly. Now, work through the non-medical factors are considered more important to reduce improper section rate.

		                        			BACKGROUND AND OBJECTIVES: An experimental model of bacterial rhinosinusitis is essential to study the pathogenesis of rhinosinusitis. To our knowledge, there hasn't been an experimental model using rats for bacterial rhinosinusitis, where Staphylococcus aureus is directly inoculated to the rat nose. Staphylococcus aureus is also a predominantly isolated bacterial pathogen in the episode of acute rhinosinusitis. The aim of this study was to develop a rat model of rhinosinusitis induced by Staphylococcus aureus, ATCC 25923. SUBJECTS AND METHOD: The infected Sprague-Dawley rats (4-6 week-old male) were applied intranasally with 40 microliter of Staphylococcus aureus, ATCC 25923, which corresponds to 108 colony-forming units per milliliter, which in turn corresponds to a No. 1 McFarland turbidity by spectrophotometer (VITEK, USA). After the 2nd, 5th, and 14th day, the rats were killed respectively. RESULTS: Nasal sinuses were then observed at low power field (x40) for changes in the amount of inflammatory cell clusters in the sinus cavity. There were significant differences in the number of inflammatory cell clusters between the infected and control rats (p<0.05). The infected rats killed at the 5th day had significantly more inflammatory cell clusters within the sinus cavities (p<0.05). CONCLUSION: Staphylococcus aureus induces acute bacterial rhinosinusitis in rats as measured by increased inflammatory cell clusters. This study demonstrates the efficacy of a rat model of acute bacterial rhinosinusitis.

		                        			OBJECTIVES: The purpose of this study is to evaluate and compare the maternal and neonatal complications of the overt diabetes with that of gestational diabetes. METHOD : The medical records of 65 pregnant patients complicated by diabetes mellitus at Eulji medical center from January, 2001 to December, 2002 were reviewed retrospectively. Thirteen patients of them were diagnosed as a overt diabetes and the others were diagnosed as a gestational diabetes. RESULTS: Maternal complications were that preeclampsia in 15.4% and preterm labor in 15.4% in overt diabetes patients and preeclampsia in 9.6%, fourth degree laceration in 1.9%, preterm labor in 3.8%, placenta abruption in 1.9%, cardiomyopathy in 1.9% and polyhydroamnios in 1.9% in gestational diabetes patients. Neonatal complications were that hypoglycemia in 38.5% and respiratory distress syndrome in 15.4% in overt diabetes patients and hypoglycemia in 25%, hyperbilirubinemia in 9.6% and shoulder dystocia in 1.9% in gestational diabetes patients. There were no statistic differences in maternal and neonatal complications in two groups when management had done. And in gestational diabetes group, maternal and neonatal complications were significantly higher in no management group than management group regardless of management types. CONCLUSION: If early detection and management were done in overt and gestational diabetes, there were no difference in maternal and neonatal complications. Regardless of types of diabetes, early detection and management were important.

		                        			OBJECTIVE: The most common operation in gynecology is hysterectomy. To compare the indications, patient characteristics and clinical outcome, complication between total abdominal hysterectomy (TAH) and vaginal total hysterectomy (TVH), laparoscopically assisted vaginal hysterectomy (LAVH). METHODS: This study was designed to analyze 147 patients of TAH (Group I) from January 2003 to September 2003, 48 patients of TVH (Group II), 108 patients of LAVH (Group III) at Eulji medical center of obstetrics and gynecology from January 2002 to September 2003. We analyzed the result with patient characteristics, parity, medical disease, history of previous operation, indication of hysterectomy, uterine weight, concurrent surgical procedure, operation time, bleeding amount, complication and length of hospital stay. Uterine prolapse was excluded in the analysis of this study. RESULTS: Patient characteristics, parity, medical disease were no differences. Number of previous operation were 63 cases (42.9%) in TAH group, 10 cases (20.8%) in TVH group, 43 cases (39.8%) in LAVH group, and the most common of operation was tubal ligation in three gropups. Most common indication of hysterectomy was uterine leiomyoma. The mean uterine weight was 374.31 +/- 250.26 gm in TAH group, 187.70 +/- 109.62 gm in TVH group and 203.26 +/- 94.92 gm in LAVH group. The mean operation time was 89.61 +/- 25.24 min in TAH group, 73.39 +/- 21.80 min in TVH group and 96.18 +/- 27.98 min in LAVH group. Postoperative complication was observed 60 cases (40.8%) in TAH group, 8 cases (16.7%) in TVH group, 19 cases (17.6%) in LAVH group. Most common complication was bleeding and required transfusion (TAH 32 cases (21.8%), TVH 3 cases (6.3%), LAVH 10 cases (9.3%)). CONCLUSION: LAVH and TVH present superior result in terms of complication when compared with TAH. LAVH and TVH have advantage of lower morbidity, less pain, shorter hospital stay and convalescence. LAVH should be considered when the vaginal approach is unfeasible, showing clear advantages over abdominal hysterectomy.
