It is rare for low-grade gliomas to disseminate to the leptomeninges. However, low-grade gliomas with dissemination to the leptomeninges have been occasionally reported in children, and have generally been associated with local recurrence. A 16-year-old boy sought evaluation for diplopia and gait disturbance. A brain magnetic resonance imaging (MRI) revealed pontine mass, which was proved to be fibrillary astrocytoma on biopsy, later. Radiation therapy (5400 cGy) was given and the patient's symptoms were improved. He was followed-up radiologically for brain lesion. Seven months after diagnosis he complained of back pain and gait disturbance. A brain MRI showed a newly-developed lesion at the left cerebellopontine angle without an interval change in the primary lesion. A spinal MRI demonstrated leptomeningeal dissemination of the entire spine. Radiation therapy (3750 cGy) to the spine, and adjuvant chemotherapy with a carboplatin plus vincristine regimen were administered. However, he had a progressive course with tumoral hemorrhage and expired 13 months after diagnosis. We report an unusual case of a low-grade brainstem glioma with spinal dissemination, but without local recurrence, and a progressive course associated with hemorrhage.

참깨줄기의 반쪽부분(部分)만이 특징적으로 변색(變色)되며 결국은 식물체전체(植物體全體)가 고사(枯死)되는 병미(病微)이 장려품종(奬勵品種)인 광산(廣産)깨와 풍년(豊年)깨가 심겨진 포장(圃場)에서 관찰(觀察)되었다. 병미(病微)은 처음에 줄기의 한쪽 부분(部分)만이 수침상(水浸狀)의 줄무늬(條斑)형태(形態)로 변색(變色)되며, 병징후기(病徵後期)에는 변색부위상(變色部位上)에 황백색(黃白色)$\sim$선홍색(鮮紅色)의 Fusarium 포자퇴(胞子堆)들이 많이 형성(形成)된다. Fusarium oxysporum에 감염(感染)된 참깨 유묘(幼苗)에서는 주로 시들음 증상(症狀)이 나타나지만, 성묘(成苗)에서는 토양접종(土壞接種)이나 상처접종(傷處接種)에 의해 줄기반쪽썩음증상(症狀)을 재현(再現)시킬 수 있었다. 본(本) 병해(病害)는 주로 생육후기(生育後期)인 7월하순(月下旬) 경에 많이 발생(發生)된다. 참깨줄기반쪽썩음증상(症狀)에서 분리(分離)한 Fusarium oxysporum의 균학적(菌學的) 특성(特性)을 이미 참께시들음병(病)에서 보고(報告)되어 있는 Fusarium 균(菌)들과 비교(比較)한 결과(結果) 본(本) 균(菌)은 F. oxysporum f. sp. sesame로 생각된다.

폐암에서 중추성 요붕증이 병합되는 경우는 드물며, 그 원인은 대개 뇌하수체로의 전이에 의한 것으로, 이런 경우 수술적 치료나 방사선 치료가 도움이 된다. 그러나 부종양성 증후군의 일부로 발현될 수도 있으며, 이 경우에는 데스모프레신으로 효과적으로 치료할 수 있다. 저자들은 갈증, 다음, 다뇨를 주소로 내원한 비소세포폐암 환자에서 수분제한검사로 중추성 요붕증을 확진한 환자를 경험하였기에 이를 보고하는 바이다.

Horses that have been retired from racing or imported from abroad are retired as broodmares. Whether at private farms or government institutes they are bred to stallions with the aim of improving fertility and enhancing the breed. Accidental deaths as a result of surgical or obstetrical complications lead to decreased productivity and economic losses to the horse breeding industry. Intussusception of the uterine horn is a frequent complication of the equine and bovine species, but rarely seen in other species. The most common causes are thought to be tearing of the placenta which is suspended from the uterus and ovaries and the weight of the placenta. Expulsion of the embryonic membranes is also thought to be a contributing factor. If symptoms are minor and treatment affected quickly, the problem will likely resolve itself. In more severe cases the uterus will prolapse completely. This case study was observed in a Thoroughbred broodmare. After treatment of dystocia, the broodmare could not stand up. She became dehydrated, collapsed, suffered colic and was euthanised. In this case was observed serious swelling vulva and perineal region by morphology, and there was seldom ascites and unusual view in thoracic and abdominal cavity after opening abdomen. However, intussusception of uterine horn involuted left uterine horn into the uterine body was observed.

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 mg 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 mg 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.

Takayasu arteritis is a chronic inflammatory disease of unknown etiology primarily affecting the aorta and its major branches and usually occurring in the second or third decade of life. Here, we report a case of Takayasu arteritis in a 10-month-old patient. The infant presented with signs of congestive heart failure and severe aortic regurgitation. Echocardiography and computed tomography angiography showed an abnormally dilated thoracic and abdominal aorta. The infant was initially treated with prednisolone, followed by commissuroplasty of the aortic valve but neither approach ameliorated the heart failure. The patient was eventually treated with a mechanical aortic valve replacement surgery at the age of 12 months, and her condition stabilized. Although unusual, this case indicates that the diagnosis of Takayasu arteritis should be considered in children with unexplained systemic symptoms, aortic valve regurgitation, and heart failure. Because severe aortic regurgitation may be a fatal complication of Takayasu arteritis, early aortic valve replacement surgery should be considered, even in very young children.

Aspergillosis in the central nervous system (CNS) is a very rare disease in immune-competent patients. There was a case of a healthy man without a history of immune-compromised disease who had invasive aspergillosis with unusual radiologic findings. A 48-year-old healthy man with diabetes mellitus, presented with complaints of blurred vision that persisted for one month. Brain magnetic resonance imaging (MRI) showed multiple nodular enhancing lesions on the right cerebral hemisphere. The diffusion image appeared in a high-signal intensity in these areas. Cerebrospinal fluid examination did not show any infection signs. An open biopsy was done and intraoperative findings showed grayish inflammatory and necrotic tissue without a definitive mass lesion. The pathologic result was a brain abscess caused by fungal infection, morphologically aspergillus. Antifungal agents (Amphotericin B, Ambisome and Voriconazole) were used for treatment for 3 months. The visual symptoms improved. There was no recurrence or abscess pocket, but the remaining focal enhanced lesions were visible in the right temporal and occipital area at a one year follow-up MRI. This immune-competent patient showed multiple enhancing CNS aspergillosis in the cerebral hemisphere, which had a good outcome with antifungal agents.

세계 인구의 고령화가 진행되는 오늘날 노인들을 위한 의료 서비스의 수요는 점차 증가할 것으로 보인다. 특히, 응급실을 방문하는 노인 환자는 일반 환자보다 다양한 질병을 갖고 있거나, 특이한 증상을 호소하는 등 복잡한 의학적, 사회적 및 신체적 문제를 가지고 있는 경우가 많다. 우리는 65세 이상의 응급실을 방문한 노인 환자의 사망률 예측을 위해 연령, 성별, 혈압, 체온, 혈액검사, 주증상명 등의 의료 데이터를 사용하였다. Feed Forward 신경망과 지지벡터기계를 각각 학습하여 사망률을 예측하고 그 성능을 비교하였다. 1개의 은닉층을 사용한 Feed Forward 신경망의 실험결과가 가장 좋았으며, 이 때 F1 점수는 52.0%, AUC는 88.6%이다. 좀 더 좋은 의료 자질을 추출하여 제안 시스템의 성능을 향상시킨다면 응급실에 방문한 노인 환자들을 위한 효과적이고 신속한 의료 자원 배분을 통해 더 좋은 의료 서비스를 제공할 수 있을 것이다.
