A 51-year-old man developed anterograde amnesia following the ingestion of glufosinate ammonium. Brain MRI revealed hyperintense lesions involving the bilateral hippocampus and parahippocampal gyrus, and the right occipital lobe. The mechanism underlying acute glufosinate ammonium intoxication and the differential diagnosis of hippocampal lesions are discussed.

It is well known that the two main variants of the anterior cruciate ligament (ACL) ruptures in an adolescent include tibial eminence fractures and midsubstance tears. Authors report a case of 17-year-old girl with simultaneous bilateral anterior cruciate ligament ruptures at the ligamento-osseus junction of tibial attachment which was treated with arthroscopic primary repair.

Bilateral coronary artery to pulmonary artery fistulas are very rare anomaly. Echocardiography, cardiac catheterization and coronary angiography of two patients having chest pain and dyspnea showed bilateral coronary to pulmonary artery fistulas. One patient had left anterior descending coronary artery stenosis and the other patient had cystic tumor. We report the good results of the surgical treatment of two patients with bilateral coronary to pulmonary artery fistulas.

2018년 싱가포르에서 북미 정상회담이라는 역사적인 이벤트가 성사되었다. 2019년 1월 1일, 김정은 북한 국무위원장이 "미국 대통령과 언제든 또다시 마주 앉을 용의가 있다"는 신년사를 발표했고 트럼프 대통령이 이에 화답하며 이후 양측 간 실무 협상이 이뤄졌다. 그 결과 2월 말, 양국 정상은 베트남 하노이 2차 정상회담에서 마주할 수 있었다. 그러나 회담은 별다른 성과 없이 결렬됐다. 6월에는 갑작스러운 남-북-미 DMZ 회동이 이뤄졌으나 북한이 갑작스레 수차례 미사일 도발을 감행하며 북미 관계는 다시 교착 상태에 빠지게 됐다. 이후 10월에는 북한 비핵화 협상을 위한 북미 양측의 실무접촉이 스웨덴 스톡홀름에서 진행됐지만 이 또한 뚜렷한 성과를 도출하지 못했다. 양측 모두 현재까지 제3차 북미 정상회담에 대한 가능성은 열어놓은 상태다. 본 경제자료에서는 2019년 북미관계 주요 내용을 정리하고자 한다. 첫 번째 장에서는 하노이 제2차 북미정상회담의 과정과 내용을 정리한다. 두 번째 장에서는 하노이 회담 이후 북미 관계를 살펴보고 남북미 정상 판문점 회동의 과정을 정리해 본다. 세 번째 장에서는 스톡홀름 북미 실무협상 전 북한의 미사일 발사와 함께 실무협상 전개의 주요사항을 정리한다. 본 자료는 다양한 언론 보도를 근거로 재구성하여 제공한다

Isolated metastasis in the extraocular muscle (EOM) is uncommon, while metastases in bilateral multiple EOMs is even rarer. Rhabdomyosarcoma (RMS) is a rare soft-tissue malignancy that usually occurs in the pediatric population and is one of the primary malignancies of isolated EOM metastasis. Here, we present a case of sinonasal RMS metastasis to multiple bilateral EOMs along with a brief review of 10 previously reported cases of RMS metastasis in EOMs.

H-reflex is a kind of late respons which can be used for the proximal nerve conduction study. Also it is a useful and widely used nerve conduction technique es to look electrically at the monosynaptic reflex. Although recordable from all muscles theoretically, H-reflexes are most commonly recorded from the calf muscles following stimulation of the tibial nerve in the popliteal fossa. But in this study, We tried to establish the normal data and to evaluate the significance of the H-reflex study in cervical radiculopathy. H-reflexes were recorded from flexor carpi radialis (FCR) muscle, extensor carpi radialis (ECR) muscle, brachioradialis (BR) muscle, and abductor digiti minimi (ADM) muscle in 31 normal adults (62 cases) and 12 patients with cervical radiculopathy. The mean values of H-reflex latency in normal control group were $16.16{\pm}1.65$ msec in FCR; $15.99{\pm}1.25$ msec in ECR; $16.47{\pm}1.59$ msec in BR; $24.46{\pm}1.42$ msec in ADM. And the mean values of side to side difference of H-reflex latency were $0.47{\pm}0.48$ msec in FCR; $0.68{\pm}0.72$ msec in ECR; $0.63{\pm}0.43$ msec in BR; $22.31{\pm}1.24$ msec in ADM. Mean values of side to side differences of interlatency time were $0.49{\pm}0.47$ msec in FCR; $0.73{\pm}0.62$ msec in ECR; $0.79{\pm}0.71$ msec in BR; $0.69{\pm}0.44$ msec in ADM. Also, there were no significant differences in H-reflex latency between right and left side. H-reflex tests in patient group with cervical radiculopathy revealed abnormal findings in 11 out of 12 patients. These results suggest that H-reflex in the upper extremity would be helpful in the diagnosis of the cervical radiculopathy.

Purpose: Bone mineral densitometry test region advised by ISCD (International Society for Clinical Densitometry) is both site in case of femur, whereas our medical center measures left femur except for few extraordinary cases. It is said that right-handers had higher mean femur BMD in the left side than in the right side, but the factor influence the femur BMD is unknown. Thus, we investigate whether testing left femur only is a adequate clinical diagnosis. Materials and Methods: Subjects were 209 right-handers and 20 left-handers patient in Asan Medical Center from July to August, 30 to 70 years of age ($51{\pm}6.7$). Subjects fill out the questionnaire on hand preference and taking regular exercise. Total BMDs of bilateral femur were measured with GE Lunar Prodigy advance densitometer, and the statistical soft ware SPSS 12.0 for windows was used for statistical analysis. Results: In the total sample of the exercise group (n=127), the difference of both femur mean BMDs are $0.001{\pm}0.127\;g/cm^2$ and the non-exercise group's (n=102) both femur difference is $0.002{\pm}0.126\;g/cm^2$, there is no significant difference. And in exercise group, classified according to hand preference, each t-value is shown at right handers (n=114) are 0.65, left handers (n=13) are -0.39. Also, In non-exercise group, right handers (n=95) are -0.78, left handers (n=7) are -0.64. In the 95% confidence limit, there was no statistically significant difference (p>0.05). Conclusions: In recently researchs, there have been differences between both femurs according to hand preference. However, Our study have no significant difference both femurs BMDs. Therefore we suggest that BMD measurement of femur has no problem only one side, except for particular case like femur operation.

Objectives : The deficit of recognition memory has been found as one of the common neurocognitive impairments in patients with schizophrenia. In addition, they were reported to fail to enhance the memory about emotional stimuli. Previous studies have shown that bilateral eye movements enhance the memory retrieval. Therefore, this study was conducted in order to investigate the memory enhancement of bilaterally alternating eye movements in schizophrenic patients. Methods : Twenty one patients with schizophrenia participated in this study. The participants learned faces (angry or neutral faces), and then performed a recognition memory task in relation to the faces after bilateral eye movements and central fixation. Recognition accuracy, response bias, and mean response time to hits were compared and analysed. Two-way repeated measure analysis of variance was performed for statistical analysis. Results : There was a significant effect of bilateral eye movements condition in mean response time(F=5.812, p<0.05) and response bias(F=10.366, p<0.01). Statistically significant interaction effects were not observed between eye movement condition and face emotion type. Conclusions : Irrespective of the emotional difference of facial stimuli, recognition memory processing was more enhanced after bilateral eye movements in patients with schizophrenia. Further study will be needed to investigate the underlying neural mechanism of bilateral eye movements-induced memory enhancement in patients with schizophrenia.

Choanal atresia may be membrane or bony, unilateral or bilateral. Approximately 90% of the choanal atresia are bony type. Unilateral choanal atresia often eludes the diagnosis because of the absence of subjective symptoms in the neonatal period. However, bilateral choanal atresia presents at birth with cyclic respiratory distress aggravated by feedings. So complete bilateral choanal atresia is considered as a neonatal emergency. Examinations for the diagnosis of chonal atresia include 1) attempt at passing a rubber catheter or probe through the patient s nose, 2) mirror examination of the nasopharynx, 3) digital examination of the nasopharynx, 4) X-ray examination after installation of radiopaque materal into the nasal cavity. But, computed tomography has become accepted method for evaluation of choanal atresia. Surgical repair of choanal atresia is accomplished via transnasal or transpalatal approach. Advantages of the transpalatal approach are improved exposure and the preservation of mucosal flap along the newly formed apertures. On the other hand, the transpalatal approach carries the risk of injury to the greater palatine neurovascular complex, and requires longer operative time. After careful physical and radiographic examinations, we accomplished the surgical repair of the complete bony bilateral choanal atresia via transpalatal approach without complications.
