질병의 정확한 진단과 적절한 치료 그리고 이에 대한 연구를 위해서는 병소에서 채취한 검체의 형태학적 소견을 관찰하는 것이 중요하다. 이러한 형태학적 변화를 관찰하기 위해서, 연구자들은 생검 조직으로 제작한 헤마톡실린-에오신 염색표본을 이용하고 있으며, 필요한 경우에는 세포의 미세구조를 관찰하기 위하여 전자현미경 검색을 시행하고 있다. 그러나, 각종질환은 점차 세분화되고, 새로운 진단기준이 소개되고 있으며, 종양의 진단에 도움을 주는 종양표지자, 그리고, 예후를 판정할 수 있는 예후인자들이 알려지고 있어서, 통상적인 헤마톡실린-에오신 염색표본이나 전자현미경 검색만으로는 이러한 종합적인 정보를 얻기가 어렵다.

The endoscopic pathological findings of gastrointestinal tract (GIT) are important in the early diagnosis of colorectal cancer. Deep learning based on convolutional nueral network (CNN) has been implemented to solve the subjective analysis problem and to increase the performance of early detection of pathological findings. However, the desired performance is yet to be achieved and CNNs are computationally complex. To solve these problems, in this paper, we propose a vision transformer based endoscopic pathological findings classification for the early detection of colorectal cancer. Publicly available endoscopic images with three pathological findings, including esophagitis, polyps, and ulcerative colitis, each with 1000 images were used. Using our approach, we have achieved a test accuracy of 98% in classifying the three pathological findings.

2001년 7월 6일 항문폐쇄와 기립불능을 보이는 10일령의 홀스타인 자우가 병리학적 진단을 받고자 경북대학교 수의과대학 병리학교실에 의뢰되었다. 이 자우는 경상북도 고령군의 어느 젖소 목장에서 2 산째 자우였다. 임상적 검사에서는 자우의 출생시 항문폐쇄에 따른 수술을 받은 상태였고 포유를 하려고 하였으나 기립이 불가능하였다. 병리학적 진단을 위해 부검을 실시하였던 바, 왼쪽 1∼3 번 늑골의 결손을 관찰할 수 있었으며 결손된 늑골쪽의 견갑골은 변형되어 있었고 왼쪽 상완골도 그 길이가 짧아져 있는 것을 관찰할 수 있었다.

최근 원전주변지역을 중심으로 한 기형가축이 발생함에 따라 이의 원인을 규명하기 위하여 우선 역학적 조사와 혈청학적 검사 및 기형송아지 , 유산·사산 태아 등의 수집가 검물을 중심으로 하여 병리학적 검사를 실시하였다. 원전주변 기형우 발생농가의 역학적 조사와 모우의 임상적 소견에서는 하동의 이상을 관찰할 수 없었다 . 수집된 가검물 (울진원전주변지역 : 3두, 월성원전주변지역 : 3두, 고리원전주변지역 : 3두, 기타지역 2두) 총 11개 농가 11두에 대한 병리학적 검사와 모우 및 자우의 혈청학적 검사에서 9두가 Akabane 병으로 진단되었고, 나머지 2 두는 곰팡이감염증 1두 그리고 간경화 l 두로 판정되었다. Akabane virus에 감염된 9두는 기형송아지, 유·사산태아로서 사지기형, 척추만곡 및 중추신경계이상(대뇌결손, 뇌수두증)등이 관찰되었다. (중략)

This study to search the diagnostic performance of shear wave elastography(SWE) in breast mass and to compare the biopsy result and stiffness obtained from shear wave elastography. Diagnostic breast ultrasonography and SWE were targeted for 157 patients who had breast ultrasonography was diagnosed mass from June 2017 to September 2017. Pathology results of 157 patients showed a benign 92 patients(Age, $44.54{\pm}11.84$) and a malignancy 65 patients(Age, $51.55{\pm}10.54$). Final evaluation, biopsy result, and quantitative SWE result were obtained and compared with each other according to Breast Imaging Reporting and Data System(BI-RADS) of diagnostic breast ultrasonography. Quantitative SWE value and pathologic result showed the highest diagnostic specificity of 83.70% in Emean and sensitivity of 89.23% in Emin. Quantitative SWE result and biopsy result is statistically significant.(p=0.000). The optimal cut-off value for malignant lesions was 66.3 kPa and 63.7 kPa, respectively, for the sensitivity, specificity, high maximum mean elasticity value(Emax) and mean elasticity value(Emean) and this showed the highest diagnostic area under the ROC curve(Az) value compared to other SWE measurement(p=0.000). The addition of SWE to conventional US in breast mass make a increase diagnostic specificity and reduce unnecessary biopsy. Therefore, it is expected that it will be helpful to analyze the breast mass using the above analysis and apparatus.

Purpose: To evaluate the clinical manifestations of various glomerular diseases in children, a clinicopathological study was performed in 52 children who had renal biopsy. The type and relative incidence of the glomerular pathologies were analyzed, and the clinical predictability and usefulness of renal biopsy in glomerular diseases were assessed. Methods: Medical records of fifty two children with renal disease who had undergone percutaneous renal biopsy under ultrasonic guidance at Chungnam University Hospital from October 1995 to August 2003 were reviewed. In addition, we compared the clinical findings before renal biopsy with the pathological diagnosis. Results: The male to female ratio was 1.6:1 and they were $9.8\pm2.6$ years old on average. The chief complaints for biopsy were hematuria in 22 cases which was the most common (42.3%), proteinuria in 16 cases(30.8%), and hematuria & proteinuria(26.9%). Among the 22 cases of hematuria, there were 15 cases of gross hematuria(68.2%) and 7 cases of microscopic hematuria(31.8%). In terms of histopathologic diagnosis, most of them were primary glomerular diseases(84.6%), which included IgA nephropathy(28.8%), thin glomerular basement membrane disease(25.0%), focal segmental glomerulosclerosis(FSGS)(11.5%), membranous proliferative glomerulonephritis(7.7%), minimal change lesion(3.8%), acute poststreptococcal glomerulonephritis(3.8%) and membranous glomerulonephritis(3.8%). The clinical manifestations and pathologic diagnosis were not correlated. Conclusion: The clinical manifestations could not predict the pathological diagnosis. Therefore, renal biopsy would be inevitable in diagnosis of glomerular diseases for effective management and assessment of prognosis.

Background: Tuberculous cervical lymphadenitis can be diagnosed by clinical findings, chest X-ray, Mantoux test, but confirmed only by excisional biopsy. The polymerase chain reaction(PCR) is now widely applied to test very small amount of pathogen and would be used to detect Mycobacterium tuberculosis in biopsied tissues and fine needle aspirates. Method: We carried out the PCR using IS-1 and IS-2 primers in 16 samples from tuberculous cervical lymphadenitis patients, and 13 samples from non-tuberculous cervical lymphadenopathy patients. Acid fast staining and culture for Mycobacterium were all negative. Results: All of 8 pathologically confirmed tuberculous cervical lymphadenitis samples showed positive PCR results, and of 5/8 clinically diagnosed samples were positive. None of 6 pathologically excluded samples were positive, and among 7 clinically undiagnosed samples 2 showed positive PCR results. Conclusion: In patients with suspected tuberculous cervical lymphadenitis, PCR could be used to detect Mycobacterium tuberculosis using biopsied tissues and even fine needle aspirates with good sensitivity and specificity.
