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.

c-erbB-2 oncogene is a normal cellular proto-oncogene coding transmembrane glycoprotein structurally similar to the epidermal growth factor receptor. Amplification of this oncogene in a variety of human adenocarcinomas has been reported and is particularly well documented in breast carcinoma. It has been suggested that amplification of this oncogene is indicative of poor prognosis and is valuable only second to the lymph node status. Using immunohistochemical staining for the c-erbB-2 protein, overexpression of this protein was analysed in 228 primary breast cancer specimens and the frequency of overexpression and the relationship between overexpression and the other established prognostic variables are evaluated. Ninty three cases out of 228 cases(40.8%) show postive oncoprotein overexpression and using the chi-squared test for a trend, a significant correlation was found between c-erbB-2 protein staining and the histological grade, lymph node status, and estrogen receptor status(P<0.05). No significant association was found between staining and the patient's age and tumor size. Most of the tumors with histological types known to have good prognosis showed negative expression. Above findings strongly suggest that expression of c-erbB-2 oncogene is another independent indicator of poor prognosis in breast carcinoma.

PURPOSE: To investigate the correlation between optic disc size and retinal nerve fiber layer (RNFL) thickness in healthy subjects and patients with normal tension glaucoma (NTG). METHODS: Optical coherence tomography was performed on 50 eyes of 50 healthy subjects and on 50 eyes of 50 NTG patients. RESULTS: The optic disc size showed a significant correlation with the RNFL thickness in healthy subjects and in patients with NTG. Significant correlations were observed between the optic disc size and the ratio of superior-to-total RNFL thickness (r=-0.283, p=0.049) and the ratio of nasal to total RNFL thickness (r=0.403, p=0.004) in healthy subjects. In patients with NTG, significant correlations were observed between the optic disc size and the ratio of superior to total RNFL thickness (r=-0.314, p=0.029) and the ratio of inferior to total RNFL thickness (r=-0.302, p=0.034). CONCLUSIONS: RNFL thickness increased significantly with an increase in optic disc size in both healthy subjects and NTG patients. The correlation between optic disc size and the ratios of each quadrant to the total RNFL thickness showed a different pattern between healthy subjects and NTG patients.
