Background: The severity of polymorphic light eruption (PLE)-is highly vari able. The results of studies of the prevalence, pathogenesis, provocation and tr eatment of PLE may be highly dependent on the severity of disease in the patient s studied. Objectives: To produce a simple, valid and reproducible method to ass ess the severity of PLE, Patients and methods: Eighty patientswere asked about t he PLE they had experienced during the preceding 12 months, using a standardized interview comprising 16 questions. The answer to each question received a score . A PLE Severity Index (PLESI) was formulated, consisting of 10 questions, with a possible total score of 2- 100. The internal consistency of the PLESI (the ex tent to which the responses to different questions correlated with each other) w as assessed by reliability analysis, using Cronbach’s method. Twenty patients were re-interviewed 7- 27 days later to assess the repeatability of the PLESI . The ease of provocation of PLE by exposure at 24- h intervals to solar-simu lated radiation was assessed on a five-point scale in nine of the 80 subjects (the EOPSSR score). Results The value of Cronbach’s α for the PLESI was 0.77 . The distribution of the PLESI was consistent with a normal distribution, with a mean value of 52.7 and standard deviation of 19.4. It had a coefficient of rep eatability of 20.1. The PLESI was positively correlated with EOPSSR (rs = 0.69, P=0.039) and the number of years since onset of PLE (rs=0.25, P=0.03). There was no association between the PLESI and the duration of persistence of the eruptio n after ceasing sun exposure (rs=0.12, P= 0.30), the development of tolerance as summer progressed (rs=- 0.14, P=0.39), gender (P=0.50) or skin type (P=0.87). Conclusions: This study has (i) validated the concept that a single score can re flect disease severity in PLE by showing that the principal characteristics of t he condition, including, for example, the extent of anatomical distribution and the ea

MYZ2型微电机用环形压敏电阻器（以下简称 MYZ2）主要用于录音机电机抑制电气干扰,电压非线性系数α（以下简称α）是 MYZ2的一项重要电参数,其好坏直接影响 MYZ2的消噪性能。目前,国内还没有专用仪器直接测量α,一般采用图1线路进行测量。当 MYZ2通过10mA 和1mA 直流电流时,分别测得两电极间的电压为 E10和 E1,再按式（1）计算得到α值。

外阴癌功能评价的可靠性及有效性

世界核心医学期刊文摘（妇产科学分册） 2005年第10期1卷 32-32页

作者： Janda M Obermair A Cella D 成夜霞 Queensland Cancer Fund PO Bo x 201 Spring Hill QLD 4004 Australia

Objectives. To assess the reliability and validity of the Functional Assessment of Cancer Therapy- Vulvar (FACT- V). Methods. Seventy- seven patients treated between January 1996 and January 2001 for cancer of the vulva completed the FACT- V, the Eastern Cooperative Oncology Group Performance Status Rating (ECOG- PSR) and the Hospital Anxiety and Depression Scale (HADS) once, 20 consecutive patients treated between February 2001 and October 2001 completed the questionnaires twice, once before surgery and at 2 months follow- up. The FACT- V scores were compared by patients’ performance status, FIGO stage, recurrence, and age, and correlated to the HADS scores. Changes in the FACT- V from baseline to 2 months follow- up were evaluated to establish FACT- V’s responsiveness to change. Results. The FACT- V’s internal consistency was adequate (Chronbach’s alpha range, 0.75 to 0.92). Patients with lower performance status, higher FIGO- stage or recurrent disease received lower FACT- V scores, indicating discriminant validity. The correlation between the FACT- V and the HADS were in the expected direction, indicating convergent and divergent validity. From pre- to postsurgery, scores in nine out of fifteen items of the vulvar cancer- specific subscale improved, while those of five items declined, indicating sensitivity of the vulvar cancer specific items to changes in patients’ well- being. Conclusions. The newly developed FACT- V provides a reliable and valid assessment of the quality of life of women with vulvar cancer. It can be used as a short measure of quality of life within research studies, and to facilitate communication about quality of life issues in clinical practice.
