Until 1972, many carcinoid tumors of the thymus were not recognized as distinct lesions and were mistakenly labeled as variants of thymomas. Thymic carcinoid tumors are unusual neoplasms that show different morphological, functional, and behavioral characteristics than those of thymomas. We report a case of a 65-year-old woman with thymic carcinoid tumor. The clinicopathological findings are discussed with a review of the literature.

Objective : Some patients with disc herniation who underwent discectomy complain of back pain after surgery and are unsatisfied with the surgical results. This study aimed to evaluate the relationship between preoperative disc height (DH), postoperative DH, and pain score 12 months after surgery in patients who underwent microdiscectomy for herniated lumbar disc. Methods : This study enrolled patients who underwent microdiscectomy at a medical center between January 2012 and December 2020. Patients with X-ray or computed tomography and pain score assessment (visual analog scale score) prior to surgery, immediately post-op, and at 1, 6, and 12 months after surgery were included. The DH index was defined as DH/overlying vertebral width. The DH ratio was defined as the postoperative DH/preoperative DH. Simple linear regression and multivariate linear regression analyses were applied to assess the correlation between DHs and leg pain scores 12 months after surgery. Results : A total of 118 patients who underwent microdiscectomy were included. DH decreased up to 12 months after surgery. The DH ratio at 1, 6, and 12 months after discectomy showed a significant positive correlation with the pain scores at 12 months after discectomy (1 month : p=0.045, B=0.52; 6 months : p=0.008, B=0.78; 12 months : p=0.005, B=0.69). Multivariate linear regression analysis revealed that the level of surgery, sex, age, and body mass index had no significant relationship with back pain scores after 12 months. Conclusion : In patients who underwent microdiscectomy, the DH ratios at 1, 6, and 12 months after surgery were prognostic factors for back pain scores at 12 months after surgery. Aggressive discectomy is recommended for lower postoperative DH ratios and Visual analog scale scores, leading to improved patient satisfaction.

이차성 대동맥장루는 아주 드물며 대동맥-장골동맥의 재건수술의 중대한 합병증으로 발생할 수 있다. 이 질환은 진성 대동맥장루와 paraprosthetic enteric fistula 로 분류할 수 있다. 이러한 합병증의 예방, 진단 및 치료는 추구해야할 문제로 되어 있다. 염증성 가성동맥류로 복부대동맥 및 장골동맥을 인조혈관으로 치환한 후 41개월에 내시경으로 Paraprosthetic enteric Fistula로 진단되어 수술을 시행한 39세 남자환자를 치험하였기에 보고한다.

The semiconductor technology for the deep submicron $regime(0.18\mu\textrm{m})$ and larger wafer $diameters(300\mu\textrm{m})$ has been increased its cost with each wafer. Hence, in order to reduce the number of characterization experiments of a new process, lithographic modeling is more important than it was. In this paper, we introduced a new method to extract Dill ABC parameters from the refractive index changes. In order to evaluate our exact method, results of experiments and calculations for several resists were compared with other methods〔1〕through the lithographic simulation.

The azygos venous system is a crucial conduit of the posterior thorax and potentially vital collateral pathway. However, it is often overlooked clinically and radiologically. This pictorial essay reviews the normal azygos venous anatomy and CT findings of congenital variations and structural changes associated with acquired pathologies.
