The first two cases of living donor liver transplantation using dual grafts in Europe.

The major limitation in adult-to-adult living donor liver transplantation (LDLT) is an adequate graft size with special regard to the safety of the donor. Only 20% of the evaluated donors are suitable to donate the right liver, depending mainly on the critical remnant liver volume. We report 2 cases of adult-to-adult LDLT using dual grafts. In the first case we implanted a left lateral lobe together with a left lobe; in the second case we used a left lateral and a right lobe. Dual graft LDLT solves the problem of graft-size insufficiency and avoids critical right lobectomy in the donor. This procedure can be safely performed and opens up the possibility of LDLT to even more families in the Western world.     

眶骨延长术治疗眼球突出的实验研究

目的探讨眶骨延长术扩大眶容积治疗眼球突出的可行性。方法1年龄山羊6只,环行截开右侧眶壁,于眶上壁放置延长器,侧向延长1.5cm,经大体、X线、干骨标本及组织学观察成骨情况。结果6只山羊眶骨得到不同程度的侧向延长,延长侧随着眶骨容量的增加,眼球突度较自身对照侧为小。结论眶骨延长术可造成山羊眶骨侧向移位,有可能成为治疗眼球过度突出的方法之一。     

Abdominal nontuberculous mycobacterial infection in a university hospital in Taiwan from 1997 to 2003.

BACKGROUND/PURPOSE: Abdominal nontuberculous mycobacterial infection is a rare condition. Continuous ambulatory peritoneal dialysis (CAPD)-associated peritonitis is the most common manifestation of infection due to nontuberculous mycobacteria (NTM). There are limited data on the clinical manifestations of nontuberculous mycobacterial infection. This study investigated the diagnostic features, clinical presentation, mycobacteriology, treatment and outcome of all abdominal NTM infections treated over a 7-year period at a major teaching hospital in Taiwan. METHODS: The medical records of all patients with a diagnosis of abdominal NTM infection from January 1997 through to December 2003 were retrospectively reviewed. RESULTS: All 11 patients with abdominal NTM infections identified during the 7-year period were included. Among these patients, six were male and five were female, with a mean age of 64.5 years. The disease manifested as peritonitis (9 patients, 82%), splenic abscess (1, 9%), or perirenal abscess (1, 9%). Most patients (73%) had underlying malignancy, most often hepatoma (45%). Immunocompromised status (liver cirrhosis, malignancy, acquired immunodeficiency syndrome) was noted in 10 patients (91%). None of our patients who developed NTM peritonitis had received CAPD. The peritoneal fluid appearance varied considerably, with no particular predominance of clear, turbid, bloody, or chylous findings. Rapidly growing mycobacteria were the major etiology (46%) of abdominal NTM infection, and Mycobacterium abscessus played a major role (27%). Overall, eight patients died, and only one patient survived longer than 1 year. Seven patients (64%) died before diagnosis. CONCLUSION: Abdominal NTM infection is frequently overlooked because of its rarity and nonspecific symptoms, with consequent delays in diagnosis and treatment. In immunocompromised patients with ascites from any cause (liver cirrhosis, malignant ascites, etc.), NTM peritonitis should be considered early in the differential diagnosis of symptoms including fever, abdominal pain and weight loss. The poor prognosis of abdominal NTM infection appears to be related to the severity of underlying conditions, most often malignancy.     

氨苯砜综合征诊治探讨——附6例报告

目的：探讨氨苯砜综合征的诊治要点：方法：对6例氨苯砜综合征患者的临床资料进行回顾性分析。结果和结论：6例氨苯砜综合征患者均为中青年，从服药到出现症状的时间较长，为9～55日.6例患者均以高热起病，起病急骤、凶险，病初均有麻疹紫癜样皮疹，皮疹多形，严重者出现尼氏征阳性或阴性的大疱和（或）全身性红皮病样皮疹；均有浅表淋巴结肿大；多数患者有血液系统损害；并均有肝损害：确诊后及时停氨苯砜，给予足量肾上腺皮质激素和（或）大剂量免疫球蛋白静脉注射，以及支持对症处理，住院12～80（中位数53）日，4例痊愈，1例病情得到控制，另1例因治疗第2日自动出院放弃治疗，死于肝功能衰竭？提示氨苯砜综合征需要及时、正确处理，否则预后不良.     

自体角膜缘上皮移植联合贝复舒治疗翼状胬肉的疗效观察

目的 观察自体角膜缘上皮移植联合贝复舒对角膜缘上皮修复的作用。方法 随机选择翼状胬肉患者98例(98只眼)，治疗组为自体角膜缘上皮移植联合贝复舒，对照组为翼状胬肉切除联合贝复舒。术后每日观察角膜上皮缺损区的修复情况，并随诊观察复发情况。结果 治疗组角膜缘上皮平均修复时间为3．1天，对照组4．2天，有显著差异性。随诊6个月发现对照组有一例复发，均未发现感染。结论 自体角膜缘上皮移植联合贝复舒可使角膜缘上皮修复时间快于翼状胬肉切除联合贝复舒。复发率均较低，表明自体角膜缘上皮移植联合贝复舒治疗翼状胬肉可以加快角膜缘上皮修复，减少复发及感染的机会。     

A feasibility study on teaching evaluation system in medical education

The purpose of this study is to develop an evaluation instrument with high feasibility and acceptability, and to quantify the outcome of evaluation, in order to set up an efficient evaluation system. Teaching evaluation with questionnaire by students has been carried out in National Yang-Ming Medical College for two years. With the support of both teachers and students, the system has been established and conducted on a regular basis. The most important purpose of evaluation is to improve the quality of teaching. During the two academic years (Sep. 1986-June 1988) of the program, the overall response rate was 44.5%, the Department of Nursing had the highest response rate, followed by Dentistry, Medicine-Post Graduate, Medical Technology, and Medicine. Taking into consideration of the year and the class size, the regression analysis found that higher year or smaller size of the class had better response rate. The response rates dropped significantly after the first academic year regardless of department or year. A total of 23 classes were included in the evaluation program and 99 courses were evaluated. All questions in the questionnaire used a 0 to 4 ordinal scale, in which 0 (improvement needed) was the low end and 4 (excellent) the high end. The mean score of the seven questions of teaching evaluation was 2.47. As a whole, the students were satisfied with the teaching. As to the categories of courses, clinical courses had better mean score than basic medical courses, and basic medical courses had better mean score than common required courses. To evaluate the effectiveness of the teaching, students' achievement was used as the outcome variable. The most important predictive variable was the method of instruction, followed by the content of lecture such as degree of difficulty of the lecture and cognitiveness of the contents. The above 3 variables explained 76% of the variation of the students' achievement. However, the significant of teachers' speech, performance and attitude were not so influential. Analysis based on the characteristics of the teachers (sex, age, position, and teaching experience), the characteristics of students (department and year), teaching environments (time and place), and the 3 categories of courses (clinical, basic medical and common required courses) showed that all the above variables only explained less then 10% of the variation of the students' achievement.
