Upper gastrointestinal bleeding is common and potentially life threatening medical emergency. Emergency endoscopy is the first choice of diagnostic and treatment measure for patients with active upper gastrointestinal bleeding. Histoacryl should be considered a second-line treatment modality when conventional treatments were failed. However, it might cause several complications. Herein, we report a case of acute pancreatitis developed after histoacryl injection therapy for active duodenal ulcer bleeding. A 71-year-old man was admitted with melena and hematemesis. On emergency endoscopy, a 2 cm sized active ulcer with bleeding from an exposedvessel was seen at the duodenal bulb. Attempts to arrest the bleeding with hemoclipping and submucosal epinephrine injection were tried, but failed. We changed the method to endoscopic histoacryl injection, and obtained hemostasis immediately. A few hourslater, after successful hemostasis, patient complained diffuse abdominal pain. Ultrasonography revealed hyperechoic heterogenous diffuse pancreatic enlargement and right pararenal space fluid collection, this ultrasonographic findings and elevated serum pancreatic enzymes are compatible with acute pancreatitis.

Asbestosis is the disease of pulmonary fibrosis caused by the inhaled asbestos fibers, and could be diagnosed clinically, in the case of exposure history to asbestos is proved, by clinical symptoms of dyspnea or dry cough, physical examonation findings, and the radiographic features. But many othder inorganic dusts would show similar findings in the chest radiogram and sometimes the exposure history is obscure, so for the exact diagnosis of asbestosis lung biopsy is needed. In Korea, there have been some reports of survey in the workplace where asbestos is handled or of asbestos related diseases. This is a case report of asbestosis with accompanying pleural plaques, who had the occupational exposure to asbestos for 30 years and the consistent clinical, radiographic and pathological findings in the lung tissue obtained by the videoscope assisted thoracoscopic biopsy(VATS).

Benign neural sheath neoplasms are not common in the maxillofacial region. These lesions can occur as solitary tumors, or they can affect many sites in the form of multiple neurofibromatosis. A solitary neurofibroma is seldom undergo sarcomatous transformation, since solitary neurofibroma is relatively radioresistant and its recurrence rate seems to be low, the treatment of choice is surgical excision. This case showed a solitary neurofibroma in the left side of the floor of mouth which occurred in a 33 - year -old female. The tumor was excised. And there is no evidence of disease. She is satisfied in function and esthetic aspect.

Methoxyacrylate계 신규 살균제 KNF 1002의 오이, 고추 및 고춧잎에 대한 잔류 양상을 조사하기 위하여 포장시험을 수행하였다. HPLC-DAD에 의한 KNF 1002의 잔류분석시 최소검출량은 오이 및 고추에서 2.0 ng 그리고 고춧잎에서는 2.5 ng이었으며, 검출한계는 오이 및 고추에서 0.02 mg/kg 그리고 고춧잎에서 0.05 mg/kg 이었다. 오이에서의 잔류량은 1회 및 2회 처리하여 1일에서 7일후에 채취된 시료에서 2.0 mg/kg에서 검출한계 미만으로 나타났다. 고추에서의 잔류량은 시설재배지의 경우 최고 0.79 mg/kg에서 0.31 mg/kg 수준으로 나타났다. 노지재배의 경우에는 0.47 mg/kg에서 0.11 mg/kg으로 나타나 시설재배의 47% 수준의 잔류량을 보였다. 고춧잎에서는 시설재배지의 경우 최고 25.20 mg/kg에서 7.38 mg/kg으로 나타났으며 노지재배의 경우에는 1.99 mg/kg에서 0.11 mg/kg 수준으로 나타나 시설재배에 비해서 6.2%정도의 잔류량을 보였다. This study was conducted to evaluate the terminal residue of a new fungicide, KNF 1002, in cucumber and pepper under greenhouse and field conditions. When a microemulsion formulation (20%) of KNF 1002 was applied once or twice during 1-7 days before harvest, its terminal residue in cucumber ranged <0.02-0.20 ㎎/㎏ under greenhouse condition. In pepper, its figure recorded 0.31-0.79 ㎎/㎏ and 0.11-0.28 ㎎/㎏ under greenhouse and field conditions, respectively. Much higher level of terminal residues was observed in leaves than those in fruits in pepper, showing 7.38-25.20 ㎎㎏ and 0.11-1.99 ㎎㎏ under greenhouse and field conditions, respectively. Cultivation condition affected evidently the residue level in pepper harvests. Residual pattern of KNF 1002 seemed to be comparable to strobilurin fungicides currently used.
TABAS: Text augmentation based on attention score for text classification model
Yeong Jae Yu,Seung Joo Yoon,So Young Jun,Jong-Woo Kim 한국통신학회 2022 ICT Express Vol.8 No.4
To improve the performance of text classification, we propose text augmentation based on attention score (TABAS). We recognized that a criterion for selecting a replacement word rather than a random selection was necessary. Therefore, TABAS utilizes attention scores for text modification, processing only words with the same entity and part-of-speech tags to consider informational aspects. To verify this approach, we used two benchmark tasks. As a result, TABAS can significantly improve performance, both recurrent and convolutional neural networks. Furthermore, we confirm that it provides a practical way to develop deep-learning models by saving costs on making additional datasets.
유지 혈액투석 환자에서 발생한 비외상성의 자발성 신파열 12예의 분석

배경 : 정상인에서 특별한 외상 없이 발생하는 자발성 신파열은 매우 드문 질환이지만 혈액 투석 환자에서는 투석기간이 장기화되면서 신낭종과 신세포암의 발생빈도가 증가로 인해 정상인에 비해 높게 나타나는 것으로 보고되고 있다. 이에 유지 혈액투석을 받고 있는 말기 신부전증 환자에서 발생한 자발성 신파열의 임상적 특성을 알아보고자 하였다. 방법 : 대상 환자는 1998년 1월부터 2003년 7월까지 가톨릭의대 3개 병원에서 유지 혈액투석을 받고 있는 환자 중에서 자발성 신파열이 발생한 12명의 환자를 대상으로 신파열의 원인, 임상증세, 치료 및 경과를 후향적으로 분석하였다. 결과 : 환자의 평균나이는 54±10세 (38-72세)였고 남자 9명, 여자 3명이었다. 일차 원인 신질환으로는 상염색체 우성 다낭신증 5명, 만성 사구체신염 2명, 당뇨병 1명, 고혈압 1명, 원인미상이 3명이었다. 신파열의 주요 임상증세는 측복부 동통이 9명이었고 육안적 혈뇨가 3명이었다. 혈액투석을 시작한 후 신파열이 발생하기까지의 기간은 평균 53±36개월 (11-103개월)이었다. 상염색체 우성 다낭신증 5명을 제외한 7명의 환자 중에서 후천성 신낭종이 발견된 환자는 6명이었다. 전체 12명 중 9명에서 신절제술을 시행하였고 나머지 3명은 수혈 등의 보존적 치료만을 받았다. 수술을 받은 9명의 환자 중 2명에서 1 ㎝ 미만의 미세 신세포암이 발견되었다. 전 환자에서 사망한 예는 없었다. 결론 : 결론적으로 혈액투석 환자에서 발생한 자발성 신파열의 주요 원인은 신낭종과 신세포 암이었으며 장기 투석 환자에서 주로 발생하였다. 그러므로 장기 혈액투석 환자에서 정기적인 초음파나 전산화 단층촬영을 시행하여 자발성 신파열의 주요 원인인 신낭종과 신세포암에 대한 추적 관찰이 필요하리라 사료된다. Background : Because of high incidence of acquired renal cyst and renal malignancy, it is suggested that spontaneous renal rupture more frequently occurs in patients receiving long-term hemodialysis than general population. This study was performed to evaluate the clinical characteristics of spontaneous renal rupture in hemodialysis patients. Methods : This retrospective study enrolled 12 hemodialysis patients who developed spontaneous renal rupture. We investigated primary renal disease, duration of dialysis, clinical symptoms and signs, radiologic findings, treatment modalities, and histologic findings. Results: The mean age of the patients was 54± 10 years old and the number of male was 9. Primary renal disease consisted of autosomal dominant polycystic kidney disease (PCKD) (n=5), chronic glomerulonephritis (n=2), diabetic nephropathy (n=l), hypertensive nephropathy (n=l), unknown cause (n=3). Presenting symptoms and signs were sudden onset of flank pain in 9 patients and gross hematuria with mild flank pain in 3 patients. Mean duration from initiation of hernodialysis to development of spontaneous renal rupture was 53±36 months. Abdominal computed tomography showed subcapsular or perinephric hematoma in all patients. Of the 7 non-PCKD patients, 6 patients had multiple acquired renal cysts. Surgical exploration was undertaken in 9 patients. Pathologic examination demonstrated small sized-renal cell carcinoma in 2 of 9 patients. Three patients were only treated with conservative management including blood transfusion. All 12 patients recovered without recurrence. Conclusion : This study demonstrated that genetic or acquired renal cyst was an important cause of spontaneous renal rupture in hemodialysis patients and presenting manifestations were sudden onset of flank pain and gross hematuria.
