This study reports the unusual complications of 22-year-old male who presented with sudden hearing loss after the right mandibular third molar extraction under local anesthesia with 3.6 ml of 2 % lidocaine. Total 8.75 ㎎ of oral dexamethasone for 1 week immediately after extraction was prescribed in department of oral and maxillofacial surgery but hearing did not improve after 1 week. As referral to otolaryngology, total 600 ㎎ of oral methylon and hyperbaric oxygen therapies were operated for 2 weeks. The hearing of patient was improved at 6 weeks after extraction but tinnitus was persisted even after 12 months. The reason and treatment were discussed with literature review, searching with the keywords [‘hearing loss’ AND (‘dental’ OR ‘tooth extraction’OR‘teeth extraction’)] in PubMed and Google scholar at October 2019. Total five cases were reported after tooth extraction with local anesthesia. The sudden hearing loss could be associated with local anesthesia containing vasoconstrictors. Early steroid (extensive medication and intra-tympanic injection) and hyperbaric oxygen therapies were recommended within 2 weeks. As a proper treatment, hearing could be improved but other additional symptoms, such as tinnitus, dizziness, might be remained.

박근양 · 김정수 · 이미영 · 오광훈 · 김일형 · 인치석 · 김종원. 유산소운동과 복합운동이 비만 여고생의 혈중지질과 적혈구침강속도에 미치는 영향. 운동과학, 제20권, 제4호, 441-448. 2011. 본 연구의 목적은 비만 여고생을 대상으로 12주간의 운동프로그램 유형별적용에 따른 혈중지질과 적혈구침강속도에 미치는 영향을 고찰하는데 그 목적이 있다. 본 연구 대상자는 BMI가 25 kg/㎡이상인 비만 여고생 16명을 대상으로 유산소운동군과 복합운동군에 12주간 참가하게 하였다. 신장(p<.001)과 체질량지수(p<.05)에서 유산소운동군과 복합운동군 모두 통계적으로 유의한 증가를 나타냈다. 체중과 체지방률에서는 유산소운동군과 복합운동군 모두 감소하였으나 통계적으로 유의한 차이가 나타나지 않았다. 유산소운동군에서 HDL-C(p<.05)은 유의하게 증가하였고, LDL-C(p<.01)은 유의하게 감소하였다. 복합운동군은 LDL-C(p<.01)에서만 유의하게 감소하였고, TC, TG에서는 두 운동군 모두 통계적으로 유의한 차이가 나타나지 않았다. 적혈구침강속도에서 유산소운동군(p<.001)과 복합운동군(p<.01) 모두 통계적으로 유의하게 감소하였으나 복합운동군에서 유산소운동군 보다 더 높은 감소율을 나타냈다. 이상의 결과를 살펴볼 때 신체조성과 혈중지질에서 유산소운동군과 복합운동군 모두 유사한 결과를 나타냈으나, 적혈구침강속도에서는 복합운동군이 유산소운동군보다 높은 감소율을 보이는 것으로 나타났다. 이는 신체조성과 혈중지질에서는 유산소 운동과 복합운동 모두 유의한 운동효과를 나타냈지만, 적혈구침강속도에서는 복합운동이 유산소운동 보다 감소율이 높게 나타난 것으로 볼 때 복합운동이 혈관 내 염증상태 변화에 더욱 긍정적인 영향을 미치는 것으로 나타났다. Park, K. Y., Kim, J. S., Lee, M. Y., Oh, K. H., Kim, I. H., In, C. S., Kim, J. W. Effects of Aerobic Exercise and Combined Exercise on Serum Lipid and Erythrocyte Sedimentation Rate in Obese High school Girls. Exercise Science, 20(4), 441-448. 2011. The purpose of this study is to examine the effect of the application of exercise program types on serum lipid and erythrocyte sedimentation rate in obese high school girls for 12 weeks. 16 obese female students with BMI over 25 kg/m2 took part in either the aerobic exercise or combined exercise group. Each group has reached statistical significant increase in height (p<.001) and BMI (p<.05). Both groups have reduced weight and the fat percentage but do not show significant decrease statistically. The aerobic exercise group has increased HDL-C (p<.05), but simultaneously decreased LDL-C (p<.01), which are read as a statistical significant change. The combined exercise group has only presented statistically significant decrease of LDL-C (p<.01). Both TC and TG has presented little statistical significant difference. Both the aerobic and combined exercise groups demonstrated the decrease of erythrocyte sedimentation rate. but the combined exercise group showed steeper decline. both groups have presented positive outcome on the body composition and blood level of HDL-C, LDL-C. When we consider that the positive decrease of erythrocyte sedimentation rate through combined exercise group came out to be higher than the aerobic one, combined exercise group had a more positive impact on the condition of blood inflammation.

Objective; Host, pathogens and environments are factors of creating dental caries. Dietary factor among environmental factors is affected by sugar contents and viscosity of food. The purpose of this study was to evaluate the viscosity and sugar contents of the Army Meal-Ready-to-Eat(MRE) and calculate the cariogenic potentiality index(CPI). Method; 7 types of MRE including hardtack were studied in the present study. Viscosity and sugar contents of each MRE were measured for 3 times by viscometer and glucose measuring machine. Cariogenic potentiality index was calculated by the formula[Cariogenic potentiality index(CPI) = 2.581343×sugar contents + 0.598324×viscosity]. Results; Army MREs had the high cariogenic potentiality index were special 1, special 3, special 2, type I 3, hardtack, FRH(Flameless Ration Heater), type S in order. Conclusion; Some of Army MREs have the high cariogenic potentiality index and may deteriorate the oral health condition of military personnel. It is recommended that broader and clinical studies are necessary to evaluate the effect of Army MRE on the oral health condition.
