Supernumerary teeth are extra teeth or tooth-like structures which may have either erupted or unerupted in addition to the 20 deciduous teeth and the 32 permanent teeth. Clinicians sometimes confront unerupted supernumerary teeth where implants would be placed. Many clinicians consider immediate placement of implant into an extracted socket as an effective technique compared to the conventional method of waiting several months for bone healing, because of the advantages such as reduction of treatment period, preservation of alveolar bone and soft tissue, etc. We could hardly find the case of immediate placement of implant after extraction of impacted supernumerary teeth and permanent teeth together. Therefore we report the case of immediate implantation following extraction of impacted supernumerary teeth and poor periodontal conditioned permanent teeth.

N/A Background : A collateral flow can be assessed and graded by coronary angiography, however, the technique does not provide any information about perfusion. Myocardial contrast echocardiography (MCE) can assess collateral perfusion and has superior spatial resolution in defining its distribution. Objective : To investigate the difference of transmural perfusion according to the angiographical collateral grade in normal myocardium, we performed MCE of collateral artery in 16 patients (m : f = 11 : 5, age: 57±13yrs.) with angina and compared the results with the angiographical grades. Methods : In six patients with preexisting collaterals on baseline angiography, we performed MCE after intracoronary injection of sonicated Hexabrix. For 10 patients without preexisting collaterals on baseline angiography, we performed angiography, MCE for recruited collateral arteries during balloon inflation of stenotic coronary arteries (2 times for 120sec.). For 12 patients who underwent PTCA, we performed pressure wire simultaneously with angiography and MCE for recruited collateral arteries during balloon inflation. Fractional collateral flow(FCF) was defined by the ratio of coronary wedge pressure to proximal pressure(Pw/Pa). Angiographical collaterals were graded according to 'Rentrop' criteria(grade 0-3). Transmural thickness (TMT) and enhanced myocardial thickness (EMT) of an enhanced segment on MCE were measured at diastolic phase. The depth of collateral perfusion was estimated by collateral perfusion index (CPI) that was the ratio of EMT to TMT. Results : There were significant differences of CPI with respect to angiographical grades according to one way ANOVA test (p<0.05). One of five patients who had no recruited collaterals showed partial enhancement confined to the epicardium with CPI of 0.24. There was significant correlation between the angiographical grade and the CPI with Spearman's Rho value of 0.93(p<0.0001). The angiographical grades were significantly correlated with FCF with the Spearman's Rho value of 0.87(p=0.0002). There was also significant correlation between FCF and CPI with Pearson's r=0.81(p=0.0016). Conclusion : The higher the angiographical collateral grade is, the higher the collateral pressure and the deeper the fractional transmural perfusion from epicardium into endocardium gets.

N/A Purpose: The aim of this study is to better understand the pattern and nature of reverse redistribution (RR) in myocardial perfusion imaging. Materials and Methods: In consecutive 20 acute myocardial infarction (MI) patients, frequency of RR was correlated with that of subendocardial MI that was detected by myocardial contrast echocardiography (MCE). RR was judged to be present when there was more than one grade of worsening in perfusion at 24 hr delayed images compared with the initial rest images. MCE evaluated the significant lack of opacification in the subendocardial myocardium relative to the subepi-cardial myocardium to suggest the subendocardial MI. Kendall's nonparametric correlation coefficiency was calculated. Results: Concordant cases were 15 of 20 (75%) and correlation was statistically significant (p=0.0285). Conclusion: Our results suggested that RR was correlated with MCE-detected nontransmural MI. (Korean J Nucl Med 2000;34:228-33)

Objective: This study was designed to analyze the clinical features of idiopathic pulmonary fibrosis patients who attended a Korean medicine hospital and the treatment effects through retrospective chart reviews. Methods: The medical records of 82 outpatients who had been diagnosed with idiopathic pulmonary fibrosis and visited the Allergy, Immune, and Respiratory System Department of Kyung Hee Korean Medicine Hospital from 8 January 2015 to 8 January 2021 were retrospectively reviewed. To assess the treatment outcomes, we used the FVC (Forced Vital Capacity), DLCO (Diffusing capacity of the Lung for CO), 6-minute walk test, and HRCT (High Resolution Computed Tomography). Results: The study group consisted of 28 females and 54 males. The median age of the patients was 67.98±11.44 years. The chief complaints were cough (n=51) and dyspnea (n=49). Other frequent symptoms were general weakness (n=8), weight loss (n=4), and a fever (n=2). A total of 77 (93.90%) patients were prescribed Korean herbal medicine, and 52 (63.41%) patients were treated with acupuncture, moxibustion, cupping therapy, ICT, or pharmacopuncture. After treatments, FVC, DLCO, the 6-minute walk test, and HRCT were maintained or worsened slightly. Conclusions: This study presented the characteristics of idiopathic pulmonary fibrosis patients treated by Korean medical therapies, and further studies of Korean medical treatments for idiopathic pulmonary fibrosis patients would be valuable.

N/A Background : The detection of residual stenosis of infarct related artery (IRA) at early stage after acute myocardial infarction (AMI) is crucial in clinical decision making for interventional revascularization. The aim of this study was to evaluate the relevancy of early dipyridamole stress myocardial SPECT to detect functionally and luminologically significant residual stenosis of IRA after AMI. Methods : Twenty five consecutive patients (M:F=19:6, age: 56±13yrs) with AMI were underwent SPECT and coronary angiography within 5 days of the attack. Infarct related arteries with FFR < 0.75 and diameter stenosis (DST) >70% were regarded to have functionally and morphologically significant residual stenosis. Reversible perfusion defect was defined if there was improvement of pefusion score more than one grade in infarct segments on rest images of SPECT compared with stress images. Results : Mean FFR and DST were 0.76±0.14 and 74±15%. SPECT showed no significant correlation with both FFR and DST with Kendall's coefficiency of 0.28 (p=0.05) and 0.13 (p=0.35). The sensitivity and specificity of SPECT to detect functionally and morphologically significant residual stenosis were 92%, 31% and 83%, 29%. Conclusion : The early dipyridamole stress myocardial SPECT after AMI dose not seem to be a useful non-invasive test for the detection of functionally and luminologically significant residual stenosis of IRA.(Korean J Med 60:106-114, 2001)

심장 지방종은 매우 드문 원발성 심종양으로 무증상으로 우연히 발견되는 경우가 대부분이다. 저자들은 감염성 대장염으로 입원한 환자에서 우연히 발견된 심장 내 종양의 의심 하에 심초음파와 심장자기공명 촬영 및 관상동맥 다절편 단층 촬영을 이용하여 좌심실내 후유두근에서 기인한 심장지방종 1예를 경험하였기에 문헌고찰과 함께 보고하는 바이다. Primary cardiac lipoma is a rare, benign, well-encapsulated tumor that is typically composed of mature fat cells. It can occur in any part of the heart, but is mostly found incidentally. Although cardiac lipoma does not require specific treatment in most cases, physicians should pay attention to this entity, which may cause arrhythmias, embolization, compression of the coronary arteries, or obstruct blood flow within the heart. In this report, we present the case of a 70-year-old woman who was admitted with a complaint of infectious colitis and incidentally found to have a cardiac lipoma in the posterior papillary muscle of the left ventricle on the basis of two-dimensional echocardiography and cardiac MRI. Given the patient`s lack of symptoms and normal cardiac function, we recommended observation without surgical exploration. After six months, the patient was in good health and showed no clinical signs or symptoms of cardiac lipoma. (Korean J Med 79:57-61, 2010)

This is a retrospective clinical study on 2,955 patients who had visited the Emergency Room of Sang-gye Paik Hospital and then been treated in the Department of Oral and Maxillofacial Surgery during recent 4 years from Aug. 2002 to Dec. 2006. The obtained results were as follows. The total number of patients was 2,955 and the ratio of male to female was 1.72:1. The age distribution peak was the 1st decade (30.8%), followed by the 3rd decade (14.3%) and the 4th decade (14.0%). Trauma (62.3%) was the most frequent cause in dental emergency patients, pulpitis (13.0%) and infection patients were next in order of frequency. In trauma patients group, facial bone injury, tooth injury, soft tissue injury were included and soft tissue injury group was most prevalent, followed by tooth injury group and facial bone group. In total patient, the ratio of admission was 3.5%. We obtained the results of the distribution of primary emergency care in the traumatic injury, causal distribution of the jaw fracture, distribution of related medical department in multiple associated injuries, distribution of emergency care in infection, causal distribution and control methods of oral bleeding, distribution of TMJ disorder. The trauma patient group was major in the dental patients who had visited the emergency room, but other various groups were included. So we should analyze the pattern and the variation of the dental emergent patient to provide the proper treatment.

Radiation therapy for malignancy of head and neck leads to secondary effects, such as mucositis, xerostomia, dental caries and osteoradionecrosis. Osteoradionecrosis is a delayed complication which causes chronic pain, infection and constant deformity after necrosis. It occurs spontaneously or after primary oncologic surgery, dental extraction or by trauma of prosthesis. To reduce the incidence of osteoradionecrosis, appropriate antibiotic usage, atraumic procedure, tension-free primary suture and hyperbaric oxygen therapy are essential. This case is about a 74 years old woman who was treated for osteoradionecrosis after extraction of right lower molar at year 2006. She had received radiation therapy for angiosarcoma on tongue at year 2004. At year 2008 the patient came to our hospital for extraction of the opposite premolar but despite careful treatment, osteoradionecrosis occurred again. She was successfully treated by surgical procedure so we report this case.

The prevalence of persistent left superior vena cava (PLSVC) in the general population has been estimated to be approximately 0.3%, as determined by autopsy. PLSVC is hemodynamically insignificant if it is not associated with other congenital cardiac anomalies, and usually goes unrecognized until a left superior approach to the heart is required. Here, we report a 60-year-old male diagnosed with dilated cardiomyopathy, who had survived an episode of sudden cardiac arrest with documented ventricular fibrillation. PLSVC was recognized incidentally while implanting an implantable cardioverter-defibrillator (ICD). The ICD was successfully implanted through the left superior vena cava via the coronary sinus using a straight stylet and an active fixation device. (Korean J Med 2014;87:328-333)

N/A Purpose: We compared estimates of ejection fraction (EF) determined by gated Tl-201 perfusion SPECT (g-TI-SPECT) with those by gated blood pool (GBP) scan. Materials and Methods: Eighteen subjects underwent g-TI-SPECT and GBP scan. After reconstruction of g-TI-SPECT, we measured EF with Cedars software. The comparison of the EF with g-TI-SPECT and GHP scan was assessed by correlation analysis and Bland Altman plot. Results: The estimates of EF were significantly different (p<0.05) with g-TI-SPECT (40%±14%) and GBP scan (43%±14%). There was an excellent correlation of EF between e-TI-SPECT and GBP scan (r=0.94, p<0.001). The mean difference of EF between GRP scan and g-TI- SPECT was +3.2%, Ninety-five percent limits of agreement were +9,8%. EF between g-TI-SPECT and GBP scan were in poor agreement. Conclusion: The estimates of EF by g-TI-SPECT was well correlated with those by GBP scan. However, EF of g-TI-SPECT doesn't agree with EF of GBP scan. EF of g-TI-SPECT cant be used interchangeably with EF of GBP scan. (Korean J Nucl Med 2000;34:222-7)
