A case of isolated Crohn's disease of appendix is reported. It is a rare disease which commonly mimics the symptoms of acute appendicitis. Review of 221 identical cases previously reported in the world literature revealed slight male predominance(1.17:1) and peak age of incidence in the third decade(24.3 yrs). In contrast to typical Crohn's disease, the rate of postoperative fistula and recurrence was minimal; 1.0% and 3.8%, respectively. Due to these differences, many consider it to be a separate disease entity from Crohn, and a new diagnostic term - "Idiopathic Granulomatous Appendicitis" - has gained wide acceptance in recent years.

Endometriosis in the abdominal wall following Cesarean section is one of the very rare condition among the extrapelvic endometriosis. Although benign, endometriosis possesses the unique ability to invade tissue and to disseminate or metastasize by hematogeneous, lymphatic route, or direct implantation. We reported the case with brief review of the literature.

Purpose: To evaluate the proportion of bevacizumab and the reason for its usage in wet age-related macular degeneration (AMD). Methods: Retrospective analysis of medical records was performed for 1,541 patients who received ranibizumab, aflibercept, or bevacizumab injection to treat wet AMD. The proportion of bevacizumab among the entire set of injections was identified. The reason for selecting bevacizumab was additionally identified. Results: During the study period, a total of 2,929 anti-vascular endothelial growth factor (anti-VEGF) injections were performed; 2,236 (76.3%) were ranibizumab or aflibercept injections and 693 (23.7%) were bevacizumab injections. The most common reason for bevacizumab usage was ‘having a 0.1 or worse best-corrected visual acuity or being unable to assure reimbursement due to the development of extensive scarring or geographic atrophy’ (297 bevacizumab injections, 42.9%). The second most common reason was ‘the inability to assure reimbursement such as extrafoveal choroidal neovascularization (CNV) or early CNV without definite fluid in the foveal region’ (201 bevacizumab injections, 29.0%). Conclusions Bevacizumab was used in 23.7% of the anti-VEGF injections to treat wet AMD. When analyzing patients’ treatment burden and financial impact, the results of the present study may provide useful information. Further multi-center studies are required to evaluate more precisely the usage of anti-VEGF drugs.

The author surveyed on the ration of central serous retinopathy (C.S.R.) cases among total out patient, distribution of sex, distribution of age, sites of affected eye, and visual acuity in 271 cases of central serous retinopathy from March, 1973 to April, 1977. Fluorescein angiography was performed in 71 cases among them. Leakages of fluorescein were analysed by pictures. The results are obtained as follows: 1. The eyes of C.S.R. were observed in 0.75% among total out patients. 2. As to the distribution of sex, male were observed in 71.4%. 3. Among 271 cases, Unilateral affected cases (83.4%), and there were no difference between right and left eyes. 4. As to the distribution of age, 4-th decade were most frequently affected in 35.4%. 5. The cases were classified by leaking pattern as followings; Type I: Leaking was unremarkable. Type II: Leaking point appeared at early arterial phase and fades out gradually. Type III: Learking point appeared at early arterial phase and increased in density gradually, but the size of leaking area wes not enlarged. Type IVa: Leaking point appeared at early arterial phase and increase concentrically in the density and size. Type IVb: Leaking point appeared at early arterial phase and increased vertically (mushroom-shaped) in its size and density. 6. Type IVa in leaking pattern was most frequently observed. 7. A single leakage was found in 39.5% of all cases. 8. The leakages of fluorescein were found most frequently in the upper area particullary in the upper nasal area of the macula.

The placements of silicone tube and silicone stent are helpful in maintaining the patency of lacrimal passage in endoscopic intranasal dacryocystorhinostomy(DCR). Hwoever, they can cause obstruction of internal ostium due to complications, such as inflammation and granuloma formation. The authors evaluated the rates of granuloma formation in 33 cases who had undergone endoscopic DCR with placement of silicone tube and silicone stent and the optimal removal timing to increase patency rates. Granuloma formation was noted in 19 of 33 cases; 12 of the 19 cases developed granuloma formation between 7 and 12 week after operation. Therefore, we concluded that the rates of granuloma formation were higher in placement of both silicone tube and silicone stent than those of silicone tube alone, and the optimal time for their removal seemed to be between 4 and 6 weeks postoperatively.

Authors performed angio-CT(portal &/or arterial CT) in 35 patients with various hepatic masses. We obtained portal CT in 32 and arterial CT in 13 patients. The contrast material was injected into superior mesenteric artery for portal CT and into hepatic artery for arterial CT after transfemoral cathetrization of these arteries. We concluded that portal CT was superior to other imaging modalities highly sensitive in detecting hepatic masses, especially, early hepatocellular carcinomas, daughter nodules, and subclinical metastatic hepatic malignancy, With this method, detection rate of early hepatocelluar carcinomas improved 62% in number of patients and 90% in number of masses. Detection rate of subclinical hepatic metastases improve 60% each in number of patients and in number of masses. It was also useful for the detection of portal vein invasion. Arterial CT was useful in differential of masses and in defining the characteristics of entire or part of the masses because this method revealed hemodynamic patterns more definitely.
