유종인(Jong In You),방슬기(Seul Ki Bang),강민석(Min Seok Kang),진경현(Kyung Hyun Jin) 대한안과학회 2020 대한안과학회지 Vol.61 No.3
목적: 망막이 관찰되지 않는 진행 백내장환자의 수술 예후와 만족도에 대해 조사하였다. 대상과 방법: 2015년부터 2017년까지 백내장수술을 받은 480명 748안을 후향적으로 분석하였다. 술 전 요인과 백내장의 진행 정도, 수술 방법, 수술 1개월 및 6개월 후 최대교정시력에 대해 조사하였다. 이 중 망막이 관찰되지 않는 진행 백내장환자 78명 91안의 술 후 만족도를 조사하였다. 결과: 고혈압은 수술 6개월 후 시력과 양의 상관관계를 보였다(p=0.004). 낮은 각막 내피세포 수, 원발개방각녹내장, 섬유주절제술, 각막이상증 혹은 각막혼탁, 안저검사상 망막이 관찰되지 않는 진행 백내장, 과숙백내장, 백내장 낭외적출술 및 낭내적출술, 수술 1개월 후 시력이 0.5 미만인 경우는 수술 6개월 후 시력과 음의 상관관계를 보였다(각각 p=0.019, p=0.002, p=0.037, p=0.001, p=0.004, p=0.012, p=0.00, p=0.00). 망막이 관찰되지 않는 진행 백내장은 수술 후 6개월 후 시력 0.5 미만의 위험도가 3.18배(p=0.003) 높았다. 망막이 관찰되지 않는 진행 백내장환자 중, 예후가 좋지 않을 것으로 기대되어 수술을 미룬 환자 10명 10안 중 6안(60%)의 최종시력은 0.5 미만이었다. 하지만, 6명(60%)이 수술 후 만족한다고 답하였으며 수술 후 만족도가 상대적으로 높았다. 결론: 망막이 관찰되지 않는 진행 백내장환자의 수술 후 최종 시력은 낮다. 그러나 진행 백내장환자 중 좋지 않은 예후가 기대되었던 환자의 술 후 만족도는 시력예후에 비해 높다. Purpose: We evaluated the surgical prognoses of patients with advanced cataract who were unable to be evaluated by fundus imaging and their satisfaction with daily life. Methods: We retrospectively reviewed 748 eyes of 480 patients who underwent cataract surgery from January 2015 to December 2017. Preoperative factors, surgical technique, degree of cataract, and the best-corrected visual acuity for 1 and 6 months after surgery were analyzed. Among 91 eyes of 78 patients with advanced cataract who were unable to be evaluated by fundus imaging, the degree of discomfort before surgery and postoperative satisfaction were evaluated. Results: Hypertension was positively correlated with visual acuity after cataract surgery (p = 0.004). Low corneal endothelial cell count, primary open-angle glaucoma, a history of trabeculectomy due to glaucoma, corneal dystrophy or corneal opacity, advanced cataract unable to be evaluated by fundus imaging, hypermature cataract, extracapsular cataract extraction, and intracapsular cataract extraction and visual acuity <0.5 after 1 month showed negative correlations with the visual outcomes after 6 months (p = 0.019, p = 0.002, p = 0.037, p = 0.001, p = 0.004, p = 0.012, p = 0.00, and p = 0.00, respectively). The risk of a final visual acuity <0.5 after cataract surgery was 3.18-fold higher in cases of advanced cataract, unable to be evaluated by fundus imaging (p = 0.003). Ten patients with 10 eyes postponed surgery due to poor prognoses, which was expected, and six patients (60%) had a best-corrected visual acuity <0.5 after 6 months. Six patients (60%), expected to have a poor prognosis were satisfied after surgery and the postoperative satisfaction was high when compared with a poor visual outcome. Conclusions: Poor surgical prognoses were expected in advanced cataract patients unable to be evaluated by fundus imaging. However, advanced cataract patients, who postponed surgery due to an unfavorable visual prognosis, showed a higher subjective satisfaction when compared with the postoperative visual acuity.

충북 청원에서 2006년도부터 2008년까지 북방수염하늘소 성충의 수종(잣나무, 소나무, 낙엽송)에 따른 우화시기와 일중 우화 탈출시간을 조사하였다. 성충은 잣나무와 소나무에서 5월 초순(2${\sim}$10일)에 우화를 시작하였으며, 6월 중순(4${\sim}$20일)에 끝났다. 하지만 낙엽송에서는 5월 중순(13일)에 우화를 시작하여 5월 하순(27일)에 끝나 두 수종에 비하여 우화기간이 짧았다. 우화시기는 수컷과 암컷 간에 차이가 없었다. 2007년에 우화한 성충의 성비는 잣나무에서 0.55, 소나무 0.46, 낙엽송 0.59로 수종간 차이는 없었다. 일중 우화탈출은 24시간 내내 이루어졌고 최대 우화탈출은 12${\sim}$14:00시로 가장 높았고(22.8%), 06${\sim}$08:00시간이 가장 낮았다. 성충은 1년에 1세대 발생 비율이 98.9%이고, 2년 1세대 발생 성충의 비율은 1.1%이었다. This study was performed to investigate the emergence timing and daily emergence from the different tree species logs (Korean white pine, Pine, and Japanese larch) at Cheongwon, Chungcheongbuk-do from 2006 to 2008. Pine sawyer adults began to emerge on early May (2${\sim}$10th day) and finished on mid-June (4${\sim}$20th day) in the Korean white pine and pine logs. However, pine sawyer adults began to emerge on mid-May (13th day) and finished late May (27th day) in Japanese larch logs, Japanese larch logs shows shorter emergence timing of pine sawyer adult compare to those of other two tree species. Emergence timing shows no difference between males and females. Sex ratios of emerged adult in 2007 were 0.55 from Korean white pine, 0.46 from Pine, and 0.59 from Japanese larch; it shows no difference among tree species. Female and male adults emerged throughout 24 hrs; 22.8% of the total adults emerged from 12${\sim}$14:00 (22.8%) and adults emerged lowest from 06${\sim}$08:00. Of the adults emerged from the logs, 98.9% was univoltine and the rest was biennial which emerged next year.

Esophageal variceal hleeding is usually caused by portal hypertension associated with liver cirrhosis. However, it might be caused by lymphadenopathy of porta hepatis in noncirrhotic patient. A 19-year-old student was admitted to this hospital because of profuse hematemesis. He had been treated with anti-tuberculosis agents of miliary tuberculosis during past nine months period. On admission, gastroduodenal fiberscopy revealed esophageal variceal bleeding, Abdominal sono- graphy disclosed nothing remarkable except thickened gallbladder wall, but computed tomography showed low attenuated lymphadenopathy in porta hepatis. Further doppler sonography demonstrated lymphadenopathy of porta hepatis with fibrosis and obliteration of rnain portal vein with collateral circulations. Laparoscopic findings suggested tuberculous peritonitis without any evidence of cirrhosis of the liver. We report a very rare case of variceal bleeding caused by lymphadenopathy of porta hepatis during anti-tubereulous treatment. (Korean J Gastroenterol 1997; 29:122-128)

Background/Aims: Gastrin exert a variety of biologic actions in the brain and gastrointestinal tract through cholecystokinin receptors. Gastrin/cholecystokinin type B receptor (CCK-BR) mRNA has been shown in some colorectal cell lines and gastrointestinal tumors. While human CCK-BR has been characterized, the relative role of their isoforms in gastrointestinal cancer remains unclear. We investigated expression of CCK-BR and its isoform in normal and malignant tissues obtained from patients with gastric cancer according to anatomic location of the primary lesion, histologic type, and extent of disease. Methods: RT-PCR was used to evaluate mRNA expression of CCK-BR and its isoforms in cancer and normal samples obtained from 44 patients with gastric adenocarcinoma. The expression of long-type isoform transcripts of CCK-BR was evaluated by Southern blot analysis. Results: CCK-BR was expressed in 33/44 (75%) of malignant tissues and 36/39 (92.3%) of normal tissues obtained from the patients. By AJCC classification, CCK-BR transcript was detected in 33.3% of patients in IA stage, 50% of IB, 54.5% of II, 81.8% of IIIA, and 100% of both IIIB and IV. Long-type isoform transcript of CCK-BR was detected in 14/30 (46.7%) of malignant tissues and 23/31 (74.2%) of normal tissues of patients with gastric cancer. Conclusions: In conclusion, the expression of CCK-BR indicates tumor grade and presence of metastatic disease, and loss of long isoform transcript of CCK-BR may be related with the processing of gastric cancer.

Ischemic colitis is a well-known disease entity. It is caused by inadequate tissue perfusion secondary to either occlusive or nonocclusive conditions which result in relative hypoxia of the colon. Mostly the cl.inical course is transient and self-limiting, but less commonly it may show fulminant transmural necrosis necessitating surgical manipulation. Recently, we have experienced three patients who complained of acute cramping abdominal pain and bloody diarrhea. On colonoscopy, the descending, sigmoid, and rectosigmiod colon showed hyperemic mucosae with petechiae alternating with pale area, the margins of which were sharply demarcated. Well-defined superficial ulceration was also present. Microscopically, the colonic mucosae of three patients revealed congestion, hemorrhage, hemosiderin-laden macrophages, coagulation necrosis, and fibrinous thrombus in the lamina propria, which were compatable with ischemic colitis of acute and/or healing phase. After conservative treatment with antibiotics and electrolyte correction for two weeks each, the colonic mucosae were nearly completely healed on follow-up examination. Above clinical, colonoscopic and histopathologic features were well compatible with transient ischemic colitis in all patients. We report three cases of transient ischemic colitis those were successfully treated with conservative management.
