Systemic tumor embolisms after pulmonary resections for malignancy are rare, but usually severe and sometimes fatal. Here, we report a case of a 70-year-old woman who underwent pulmonary resection for lung cancer and subsequently developed acute arterial occlusion of the lower extremities caused by a tumorous embolus.

Purpose: To investigate the flow characteristics using different thresholding methods on a choriocapillaris optical coherence tomography angiography (OCTA) image complemented with a structural En Face image. Methods: The 42 choriocapillaris OCTA images from healthy subjects were obtained with swept-source OCTA device and the 3 × 3-mm area OCTA images were processed with ImageJ. Using a raw choriocapillaris OCTA image and structural En Face image, we adjusted the different structural signal intensity. Then, the raw images and adjusted images were binarized with a global threshold and an auto local threshold using the Phansalkar method at 1- or 2-intercapillary distance. Then, the mean area, number, and size of the flow void, were compared among the images using different thresholding methods. Results: Mean flow void area, number, and size were different according to the different binarization method both in raw and adjusted images (all p < 0.001). The mean flow void area analyzed with global threshold method were well correlated with those with auto local threshold method both in raw and adjusted images (all intraclass correlations, >0.929). Conclusions Flow void features varied according to the different binarization methods but showed good correlation. The flow void characteristics according to the different binarization methods should be considered for the analysis of the choriocapillaris OCTA images complemented with a structural En Face image.

STUDY OBJECTIVE: determine the level of medical care required for mass gatherings and describe the types of medical problems encountered in a religious mass gathered ceremony. DESIGN: Standard charts and a four-tiered triage system(minor, moderate, urgent, and emergent) were developed before the event. The triage system was applied to each chart retrospectively by a single emergency physician. SETTING: Medical staff(10 physicians,13 nurses,1 pharmacist, and 54 first-aid attendants) were based in 8 advanced life support (ALS) clinics. INTERVENTIONS: First-aid attendants referred patients to the clinics, where nurses conducted initial assessments and referred patients to physicians at the venue. Three ambulances were stationed at the venues. RESULT: 22 trauma patients were developed and 183 medical complaints were encountered. Only 7 urgent medical problems were encountered.

After the performance of 100 coronary cineangiographies in 100 paitents who were adminitted to Soonchunhyang University Hospital under the diagnosis of ischemic heart disease from July 1986 to October 1987, we observed the coronary collateral circulation and measured the ejection fraction, circumferential fiber shortening, left ventricular end-diastolic pressure and pulmonary artery wedge pressure in 52 paitents who had 50% or more stenosis in one or more coroanry arteries. The results were as follow : 1) The collaterall circulation was observed in 16 patients(30.8%) of the 52 patients and it was developed mainly(87.5) in patients with 90% or more coronary artery stenosis. In patients with stenosis of less than 90%, however, collateral circulation was observed rarely(12.5%). 2) The left ventricular wall motion abnormality was severe in the group without collateral circulation. 3) The collteral circulation was most frequently developed in patients with severe right coronary artery stenosis and most of the routes were supplied from contralateral coronary arteries. 4) There was no significant difference in ejection fraction, circumferential fiber shortening, left ventricular end-diastoic pressure and pulmonary artery wedge pressure between the 2 groups with and without coronary artery collateral circulation.
