Foreign body ingestion is a frequent event in the pediatric age group, but the incidence of foreign bodies in the appendix is very low. The authors report a case of ingested foreign body trapped in the appendix in a 7-year-old girl. The foreign body was successfully treated by laparoscopic appendectomy under fluoroscopic guidance.

Purpose: The purpose of the present study was to evaluate the contributing factors to the lymph node status as well as to define the impact of preoperative concurrent chemoradiotherapy (CCRT) on the number of lymph nodes retrieved in mid-low rectal cancer. Materials and Methods: We retrospectively analyzed 277 patients who underwent curative surgical resection for mid-low rectal cancer between 1998 and 2007. Eighty-two patients received long course preoperative CCRT followed by surgery. Results: A mean of 13.12±9.28 lymph nodes was retrieved. In a univariate analysis, distance from the anal verge, pT stage, pN stage, lymphovascular invasion, preoperative CCRT had significant influence on the number of lymph nodes retrieved. In a multivariate model, patients in the CCRT group had fewer retrieved lymph nodes than the non-CCRT group (p<0.001). Both univariate and multivariate analyses showed that the ypN0 group had fewer retrieved lymph nodes than the ypN1-2 group (p=0.027) in the CCRT group. Conclusion:Preoperative CCRT was an independent risk factor for failure to harvest an appropriate number of lymph nodes, and node-negative patients who received CCRT had fewer lymph nodes harvested.
L2 Syntax-Semantics Interface of Wh-Questions
안영재 대한영어영문학회 2019 영어영문학연구 Vol.45 No.1
This article reports the results from a truth-value judgement task that investigates Korean speakers’ interpretation of complex and ambiguous wh-questions in English to identify the role of first language knowledge and Universal Grammar (UG) in second language (L2) acquisition. I examine this in the context of strong crossover (SCO) configurations in English. The findings demonstrate that the SCO effect is operative at the advanced levels of acquisition but not at the intermediate levels of acquisition, supporting the Feature Reassembly Hypothesis (Ladiere, 2009). I interpret this as indicating that L2 knowledge of phenomena at the syntax-semantics interface is constrained by UG.

목적: 다발성 조기위암은 전체 조기위암 중 4.5~11.7%를 차지한다. 본 연구는 다발성 조기위암의 임상병리학적 특징을 조사 분석하여 그 의의를 알아보고 치료방침의 수립에 도움이 되고자 시행하였다. 대상 및 방법: 1994년 1월부터 2004년 12월까지 11년간 연세대학교 의과대학 외과학교실에서 위선암으로 진단받고 근치적 위절제술을 시행한 2,281예의 조기위앙을 대상으로 의무기록을 후향적으로 조사 분석하였다. 결과: 다발성 조기위암은 총 91예(4.0%)였으며 2개의 병변이 81예, 3개가 9예, 4개가 1예였다. 총 102예의 보조병변 중 64예(62.7%)는 크기가 10 mm 이하였으며 83예(81.4%)는 주병변과 같은 부위에 위치하였다. 가장 흔한 조직학적 분류는 분화형으로 52예(57.1%)였다. 점막암은 49예(53.8%)였으며 점막하층암은 42예(46.2%)였고 림프절 전이는 6예(6.6%)에서 발견되었다. 단발성 조기위암과 비교하였 때 전체 생존율에서 통계학적으로 유의한 차이가 없었다. 결론: 다발성 조기위암은 단발성 조기위암과 임상병리학적으로 매우 유사하며 생존율에서도 차이가 없었다. 그러므로 다발성 오기위암의 치료에 있어서 일반적인 조기위암의 치료지침에 준한 방법을 적용할 수 있으며, 조기위암의 수술 전후 잔위에 보조병변을 남기지 않기 위하여 세심한 주의가 필요하다. Purpose: Multiple early gastric cancer (MEGC) accounts for between 4.5% and 11.7% of all early gastric cancers (EGC). We investigated the treatment of MEGC from the viewpoint of the clinicopathologic features of the disease. Materials and Methods: 2,281 patients with EGC underwent gastric resection at the Department of Surgery, Severance Hospital during the 11 years between January 1994 and December 2004 and we carried out a retrospective analysis of these patients. Results: There were 91 cases of synchronous MEGC (4.0%) according to the diagnostic criteria of Moertel: there were 81 double, 9 triple and 1 quadruple lesions. Of the 102 accessory lesions, 64 (62.7%) were less than 10 mm in diameter and 83 (81.4%) were located in the same region as the main lesion. The most frequent histologic type of main lesion was a well differentiated adenocarcinoma, which was found in 52 cases (57.1%). There were 49 mucosal main lesions and 42 submucosal main lesions. Lymph node metastasis was detected in 6 cases (6.6%): 1 in mucosal lesions and 5 in submucosal main lesions Conclusion: Solitary EGC and MEGC had very similar clinopathological features and a similar prognosis. Therefore, we believe that the general EGC treatment guidelines can be applied for multiple EGC. It is important to evaluate the whole stomach before and during the operation and then after examining the resected specimen.
