When oral cancer develops in the maxilla, oro-nasal communication occurs after surgical treatment including removal of the primary site. Restoration through an obturator is necessary to prevent food from storing due to non-oral opening, and to ensure proper pronunciation and aesthetic restoration. In this case, the patient was treated with right hemi-maxillectomy due to oral cancer and has residual abutment and poor periodontal support due to the effect of head and neck radiotherapy. The obturator was treated with a hybrid telescopic double crown denture. Reporting a successful prognosis in 18 months of follow-up.

Hybrid telescopic double crown have ever been good treatment option for patient with periodontally unfavorable few remaining teeth for successful prognosis. Tooth and implant combined telescopic double crown can be used for improving retention and support for denture with strategically placed implants on edentulous ridge. In this case, an 55-year-old female patient had chronic periodontitis with few remaining teeth on maxilla and fixed partial prosthodontics on mandible. Treatment of hybrid telescopic double crown with friction pin lasted 9.5 years only with natural teeth. After 9.5 years, additional implants was installed due to fracture of cast-posted abutment teeth. After implantation, tooth and implant combined double crown had fabricated. Through re-treatment, no complications of new denture has been found during 2 years follow up. This case presents fair prognosis of tooth and implant combined double crown denture in periodontally unfavorable condition.

PURPOSE: The objective of this literature review was to analyze the cumulative survival rates (CSRs) of rigid and non-rigid double-crown-retained removable dental prostheses.MATERIALS AND METHODS: Screening of the literature published from January 1995 to December 2019 was performed by using electronic data base (Pubmed) and manual search. The CSRs of rigid and non-rigid double crown removable dental prostheses were investigated.RESULTS: A total of 403 articles were reviewed and 56 relevant articles of them were selected. Subsequently, 25 articles were included for data extraction. These articles were classified according to rigid and non-rigid type double crowns and further subdivided into teeth, implants, and teeth-implant combination types. The CSRs of rigid type double crown ranged from 68.9% to 95.1% of 5 to 10 years in tooth abutments, 94.02% to 100% over a 3-year mean observation periods in implant abutments, and 81.8% to 97.6% in tooth-implant combination. Non-rigid type double crowns had various CSR ranges from 34% to 94% maximum during 10 years observation in teeth abutment. The CSRs of non-rigid type had over 98% in implant abutments, and ranged from 85% to 100% in tooth-implant combination.CONCLUSION: The CSRs of double crowns varies according to types. With accurate evaluation of the remaining teeth and plan of the strategic implant placement, it could be successful treatment alternatives for partially or completely edentulous patients.

Objectives: ：The purpose of this study was to identify the change in the reasons for referrals before and after the COVID-19 outbreak among students who were referred to the one hospital-linked Wee center in Dalseo-gu, Daegu. Methods: ：324 students who were referred to one hospital-linked Wee center for personal counseling from January 1, 2019 to December 31 were included. In the initial session of individual counseling, 3 of the chief reasons among 27 emotional and/or behavioral problems were indicated. This reason was divided into before and after COVID-19 to determine whether there is a difference, and whether there is a difference between before and after COVID-19 depending on the school level. Results: ：The most frequent emotional and/or behavioral problem was ‘interpersonal problems’ in both pre- COVID-19 and post- COVID-19 groups. In post- COVID-19 group, ‘anxiety’ was significantly increased, whereas ‘conduct problems,’ ‘impulsivity’ and ‘inattention’ were significantly decreased. In elementary students group, only ‘conduct problems’ was significantly decreased after COVID-19 and the same result was shown in middle and high school students group. Conclusions ：The study showed that after COVID-19 pandemics in Daegu the difference of students’ problems was noted, and internalizing problems seem to increase rather than externalizing problems. This result calls upon schools to plan for students’ further mental health care measures.

Although narcotic analgesics are potent releasers of histamine, IgE-mediated allergic reactions to these drugs are rare. Here we report the case of a 56-year-old male who suffered from chronic urticarial and analgesics-induced skin rashes. He visited our allergy clinic to determine alternative analgesics before undergoing surgery. A drug provocation test showed a positive reaction to aspirin, but negative reactions to acetaminophen and celecoxib. Despite careful attention to his drug regimen, during surgery he developed generalized urticaria and flushing. Skin tests of allergy to latex, lidocaine, propofol, rocuronium, flomoxef, meperidine, palonosetron, pyridostigmine, and fentanyl yielded negative results, except for the prick and intradermal tests with meperidine. Thus, this patient had both an aspirin/non-steroidal anti-inflammatory drugs idiosyncrasy and an IgE-mediated hypersensitivity to meperidine.

Primary adrenal lymphoma is extremely uncommon. The tumor is accidentally discovered by abdominal ultrasonography(USG), computed tomography(CT) or magnetic resonance imaging (MRI) in patients with nonspecific symptoms and diagnosed at operation or autopsy. In this case, a 60-year-old man was admitted for the evaluation of mild left frank discomfort for two months before admission. The abdominal USG was performed and showed the dense masses in both adrenal glands. The laboratory tests including blood count, chemistry and hormonal tests showed the normal levels except for the basal ACTH level of 108 pg/ml(normal range: 9~52 pg/ml). The 123I MIBG scan was normal. The bilateral adrenalectomy was done. The tumor was diagnosed as diffuse large B-cell non-Hodgkin's lymphoma(NHL) according to the Revised European-American lymphoma(REAL) classification. He was treated with the adjuvant combination chemotherapy of CHOP(cyclophosphamide, adriamycin, vincristine and prednisolone) but expired due to sepsis after the second chemotherapy. We describe the first case of primary bilateral adrenal NHL in Korea. Primary adrenal lymphoma should be included in the differential diagnosis of suprarenal mass.

A 71-year-old man was admitted due to abdominal distension and periumbilical pain. He was diagnosed as having mucinous ductal ectasia (MDE) of the pancreas three months prior, but refused an operation. Three months later, an abdominal computed tomography revealed more dilated pancreatic duct, newly developed liver metastasis and ascites in comparison with previous findings. Fine-needle aspiration cytology of the cystic lesion in the pancreatic head was conducted and yielded adenocarcinoma. Also, an ascitic fluid cytology determined adenocarcinoma. This patient was diagnosed to be inoperable and received palliative chemotherapy and pain control. The patient expired 5 months after the initial diagnosis.

OBJECTIVE: The objective of this study was to compare perinatal outcomes of pregnancy-induced hypertensive and normotensive women experiencing abruptio placentae, Our hypothesis is that pregnancy-induced hypertensive women have a less favorable perinatal outcome than do normotensive women. METHODS: Women with the diagnosis of abruptio placentae delivered between August 1, 1989 and December 1, 1996, composed the study group (n=92) in this case-control study. The women with abruptio placentae were divided according to their hypertensive (n=37) or normotensive (n=55) status. Maternal and neonatal medical records were reviewed and abstracted for demographic variables, antepartum complications, delivery route, abruptio placentae grade, neonatal gender, birth weight, Apgar score and perinatal mortality. We compared these perinatal outcome variables between the pregnancy-induced hypertensive and normotensive pregnant women. RESULTS: The incidence of abruptio placentae was 0.35%. The two groups of woman wne similar with regard to age and parity. Abruptio placentae grades 2 occurred more often in hypertensive women (P=0.0053). Pregnancy-inducedhypertensive women were similar to normotensive women with regard to antenatal complications. The mean gestational age of delivery, delivery route, neonatal weight and sex were similar between two groups of women. Neonates from pregnancy-induced hypertensive women were no more likely to have low 1 and 5-minute Apgar score or to die than those from normotensive women. Statistical analysis was performed with two-tailed independent t-test and Kruskal-Wallis analysis. CONCLUSION: Although pregnancy-induced hypertensive women experiencing abruptio placentae are more likely to have grade 2 abruptio placentae with fetal distress, the overall perinatal outcome was not significantly different from that of normotensive women experiencing abruptio placentae.

BACKGROUND: In patients with chronic obstructive pulmonary disease(COPD), it is well known that hypoxemia increases the frequency of VPB, which is associated with the poor prognosis such as sudden death. The aim of this study is to evaluate the effect of short and long-term low flow oxygen therapy on the development of VPBs in patients with COPD by correcting the hypoxemia. METHOD: In 19 patients with COPD, oxygen saturation and VPB are monitored by pulse oxymeter and 24-hour Holter EKG, with room air and the 1st and the 8th day during oxygen therapy by nasal prong (2L/min). RESULTS: The arterial oxygen saturation was significantly higher on the 1st day of oxygen therapy compared with breathing room air, and also higher on the 8th day of oxygen therapy than on the 1st day. We found that there was significant correlation between the minimal value of the arterial oxygen saturation and the mean value of the arterial oxygen saturation. The number of VPBs per hour was significantly higher on the 1st day of oxygen therapy compared with breathing room air, and also higher on the 8th day of oxygen therapy than on the 1st day. There was no significant correlation between the decrease of the frequency of VPBs and the increase of the minimal arterial oxygen saturation. But, because of the low p value as 0.056, The correlation is highly suggested. CONCLUSION: With oxygen therapy, the arterial oxygen saturation was increased and the number of VPBs was decreased, and with long-term oxygen therapy more than 7days, the number of VPBs was more decreased in patients with COPD.

BACKGROUND: It has been demonstrated that within 2 weeks following acute myocardial infarction (AMI), exercise-induced ST-segment depression (STD) indicates subendocardial ischemia in the viable myocardium within infarcted or remote area from the infarction. Exercise-induced ST-segment elevation (STE) in leads with abnormal Q wave is associated with left ventricular dysfunction or aneurysm rather than transmural ischemia. We studied whether each pattern of ST-segment shift on exercise ECG during recovery phase following AMI is correlated with the perfusion status of infarcted myocardium evaluated by myocardial contrast echocardiog-raphy (MCE), regardless of findings of coronary angiography (CAG). METHOD: Study population was consisted of 25 patients with AMI (anteior wall: 11 patients, inferior wall: 14 patients, mean age=57.3+/-8.9years). Patients underwent exercise ECG and coronary angiography at 10 days post-AMI. After CAG, sonicated Hexabrix was injected into both coronory arteries alternatively and 2-D echocardiography was taken in parasternal short axis, apical 4, and 2 chamber views. To analyze the echocardiographic image semiquantitively, left ventricle was divided into 20 segments and perfusion status was graded as good, partial, and no opacification. RESULT: All patients with exercise-induced STE (n=8) in Q-leads had patent infarcted-related artery and poor collaterals on CAG, which was associated with poor or no opacification of infarcted myocardium on MCE. Patients with exercise-induced STD (n=9) frequently had closed infarct-related artery (67%), but good opacification of infarcted myocardium was shown by retrograde perfusion via collaterals, which was commonly seen in patients with multivessel disease. CONCLUSION: In early recovery phase of acute myocardial infarction, exercise-induced ST elevation in Q leads was associated with poor perfusional status in infarcted myocardium, even with patent infarct-related artery on CAG, while exercise-induced ST depression was frequently seen in the good perfusional status despite of closed infarted-related artery, which was commonly observed in patients with multivessel disease.
