  • Background; Pleural micro-metastasis of lung cancer is detected by touch print cytology or pleural lavage cytology, but its prognostic impact has not elucidated yet. We hypothesize that recurrence may depend on the amount of tumor cells disseminated in pleural cavity, if the invasiveness of all cancer is the same. To predict the amount of tumor cells disseminated in pleural cavity, we need pleural surface area, distributed pattern of cells and concentration of cells per unit area. Human pleural surface area has not reported yet. In this report, we calculate the normal human pleural surface area using CT image data processing. Methods; Twenty persons were checked CT scan, and we obtained the data from each image. In order to calculate the pleural surface, the outline of lung was firstly extruded from CT image data using home-made Digitizer program. And the distance between CT images was calculated from the extruded outline. Finally a normal human pleural surface was calculated from function between the distance of consecutive CT images and the calculated length. Results; Their mean age is $65{\pm}12$ years old (range $26{\sim}77$), body weight is $62{\pm}9\;kg\;(48{\sim}80)$, and height is $167{\pm}6\;cm\;(156{\sim}176)$. The number of images used is $36{\pm}7\;(24{\sim}51)$. Pleural surface area is $211,888{\pm}35,756\;mm^2\;(143,880{\sim}279,576)$. Right-side pleural surface area is $107,932\;mm^2$ and Lt is $103,955\;mm^2$. Costal, mediastinal and diaphragmatic surfaces of right-side pleura are $77,483\;mm^2,\;39,057\;mm^2,\;and\;8,608\;mm^2$ respectively, and left-side are $72,497\;mm^2,\;35,578\;mm^2,\;and\;4,120\;mm^2$ respectively. Conclusion; Normal human pleural surface area is calculated using CT image data at first and the result is about $0.212\;m^2$.

  • 배 경: TREM-1은 중성구, 단핵구, 대식세포 표면에 존재하는 세포표면수용체로, 세균에 의해 그 발현이 증가하여 여러 염증전달물질을 증폭시키는 역할을 한다. 저자들은 삼출성흉수를 가진 환자의 혈청과 흉수에서 soluble (s) TREM-1을 측정하여 흉수의 원인진단에 대한 유용성을 알아보고자 하였다. 방 법: 2003년 3월부터 2006년 12월까지 삼출성흉수로 입원한 환자 45명을 대상으로 하여, 혈청과 흉수에서 human sTREM-1 항체를 사용하여 면역점적법(immunoblot assay)으로 sTREM-1을 측정하였다. 원인질환에 따라 결핵성, 부폐렴성, 악성흉수로 나누어 비교하였다. 결 과: 혈청 sTREM-1은 원인질환 별로 유의한 차이를 보이지 않았으나, 흉수 sTREM-1은 원인질환별로 유의한 차이를 보였으며(p=0.011), 특히 부폐렴성흉수의 sTREM-1이 결핵성흉수와(p<0.05) 악성흉수보다 유의하게 높았다(p<0.05). 부폐렴성흉수를 진단하는 데 흉수 sTREM-1의 유용성을 평가하고자 ROC 곡선을 그린 결과 곡선밑면적은 0.818이고 (p=0.001), 흉수 sTREM-1의 cutoff 값을 103.5pg/mL로 하였을 때 민감도가 73%, 특이도가 81%이었다. 결 론: 흉수의 sTREM-1은 삼출성흉수 중 부폐렴성흉수를 진단하는 유용한 지표로 판단된다.

  • An 8-year old intact female poodle was presented to clinics due to abdominal distension, anorexia, and labored breath associated with pleural effusion. Intra-operative findings revealed multiple neoplasm of the greater omentum, involving anterolateral abdominal wall, sterna surface in the pleural cavity and diaphragm. These masses were 0.1~0.5 cm in diameter and extended to ovaries, pancreas, and serosal surface of stomach. Microscopically, most neoplastic cells had oval nuclei with prominent nucleoli and abundant eosinophilic cytoplasm. In deeper area, neoplastic acinus or glandular structures showed invaginated growth resembling adenocarcinoma. High mitotic figures were observed. By immunohistochemistry, the neoplastic cells were strong positive both cytokeratin and vimentin. The present case described for malignant mesothelioma in a dog. Our findings might be helpful for diagnosis and information and helped the clinics choose the treatment including chemotherapy such as cisplatin.
