Postgraduate qualifications of British doctors

Among British-qualified doctors of 1974 and 1977, about 80% held postgraduate qualifications of some kind. The commonest qualifications were DRCOG, MRCP and MRCOG. There were considerable differences between medical schools in the numbers of qualifiers taking various examinations. Apart from the MRC Psych, DRCOG and Family Planning Certificate, qualifications were more commonly held by men than women. Tables show the type of work being done 9-13 years after leaving medical school by holders of various postgraduate qualifications; e.g. 60% of MRCP holders were working in medicine or a medical specialty and 84% of FRCS holders in general surgery or a surgical specialty. Discussion deals with the plurality, specificity, variability, perceived necessity, sufficiency, international utility and career significance of British postgraduate qualifications.

Pediatric lupus versus adult lupus role of the laboratory

Systemic lupus erythematosus (SLE) is the archetypical immunologic disease. Approximately 20% of patients present in the first two decades of life. This article highlights some of the differences between pediatric and adult onset lupus.Children are defined as different from adults on the basis of age. Lupus presents with different gender ratios based on hormonal or pubertal status with more significant skewing toward female patients in the childbearing years. Female patients in the childbearing years appear to have a higher relative risk for mortality. Despite this, children have greater disease severity at onset based on the number of patients who present with significant organ inflammation, the amount of corticosteroids required and the abnormalities in lupus serologies including autoantibodies and low complements. Children present frequently with congenital and acquired complement defects. Children have an increased risk of infections that can be confused with lupus. They have a higher risk of serious pneumococcal infection and may have less protection from vaccinations received at the time of disease onset.The clinical immunology laboratory is critical in the diagnosis and treatment of pediatric SLE. The rapid analysis and transfer of laboratory results can be life saving for the child with suspected new onset lupus. The laboratory is also helpful in determining disease activity through analysis of immunologic trends over time in pediatric lupus patients. This is especially important in the noncompliant adolescent patient who has a correlation between disease activity and lupus serologic tests. Finally, the clinical immunology laboratory is an important tool for better understanding of the immunologic phenomena associated with lupus and of disease pathophysiology.     

SARS死亡病例的实验室检查特点

目的：了解严重急性呼吸综合征(SARS)死亡病例的临床特点，为SARS重症病例的诊断、治疗及预后判断提供帮助。方法：对我院2003年1月至4月底收治的102例确诊非典患者中的5例死亡病例的流行病学及实验室检查资料进行回顾性分析。结果：死亡病例均为男性，平均49岁，从发病到入院平均7．6d，从住院到确诊平均1．2d；从住院到死亡平均14．4d，从发病到死亡平均为22d。死亡病例粒细胞总数和百分比均明显升高，多数患者淋巴细胞计数和百分比降低(4／5)，血红蛋白均呈进行性下降。死亡患者除已见报道的ALT、AST、LDH、CK升高及低钙血症外，GLU均明显高于正常而ALB均明显降低；大多数患者TP、PA等多项生化指标均出现明显下降而脱氧血红蛋白百分率(HHb)明显上升，同时伴有低磷、低镁血症。结论：SARS死亡病例多项实验室指标均会出现明显异常，动态监测这些指标有助于SARS患者的诊断、治疗及预后判断。     

Benefits from peer teaching in the dental gross anatomy laboratory

This study examined the impact of implementing a rotating dissection schedule on the attitudes and performance of first-year dental students in the gross anatomy laboratory at the University of Kentucky. In 2002-2003, half of the students assigned to each cadaver dissected the assigned objectives during the first 90 min of the laboratory session. During the last 30 min, the non-dissecting group members came into the laboratory and had the day's dissection demonstrated and explained to them via peer instruction. Dissection responsibilities rotated with each laboratory session. Eighty-eight percent of student participants were satisfied with the rotating dissection approach according to a mid-term survey, and this satisfaction level remained unchanged at the end of the semester for most students. Students' perceptions of the quality of peer laboratory presentations varied, with only 44% rating them as good or better. Eighty percent of students perceived that rotating dissection did not impede their performance, and this was confirmed by analysis of grade data. Student satisfaction and the ability to devote additional weekly curriculum time to studying anatomy in a very compressed curriculum were the main student-described benefits.     

中国急性心肌梗塞的疾病经济负担

主要通过对急性心肌梗塞疾病经济负担的研究，总体描述进行二线预防的重要性。资料主要来源于中文文献检索、政府统计报表。主要利用直接医疗费用来计算疾病经济负担，而未考虑直接非医疗费用和间接费用。中日急性心肌梗塞的发病率约为45／10万。55／10万。城市高于农村，男性高于女性。在2000年，急性心肌梗塞的死亡率在城市为32．39／10万，农村为17．99／10万，其死亡率随年龄增长而相应增长。与发病率一样，城市高于农村，男性高于女性。25岁以上人群因急性心肌梗塞而损失的DALY在2000年为3．57DALYs／千人口。怎性心肌梗塞的直接医疗费用在国家卫生部部属医院为28257元／例，省级医院为8663元／例，县级医院为5447无／例。测算2000年急性心肌梗塞的疾病经济负担为13亿元。19亿元。但由于只有10．6％的急性心肌梗塞病人得到临床床治疗，因此，本测算结果可能低估了在中国实际发生的疾病经济负担。     

如何加强局部解剖学教学中的专业英语学习

医学专业英语教学是大部分医学院校教育的薄弱环节 ,作者认为应该在每门专业课中加强专业英语的教学。本文从局部解剖学教学的角度 ,提出一些解决措施 ,包括提高学生对专业英语的认识和学习动力、结合公共英语、构词法的教学、加强预习复习、启发式教学等 ,来提高局部解剖学专业英语的教学质量。
