Vesicular pityriasis rosea: response to erythromycin treatment

Pityriasis rosea (PR) is a relatively common disease although its aetiology has not yet been identified. It occurs worldwide and there is no racial susceptibility factor. It usually affects teenagers and young adults between 10 and 35 years of age. Typical PR is much easier to diagnose than the rare atypical forms. We report a rare case of vesicular PR in a black woman who had vesicular lesions limited to her palms and soles in addition to regular typical lesions. We devised an efficient oral erythromycin treatment for this patient.     

环孢菌素A阻断人HL－60抗药性细胞于G_1期而诱导敏感细胞凋亡

进一步研究了抗三尖杉酯碱的ＨＬ－６０细胞（ＨＲ２０）抗细胞凋亡的机制及该抗性和抗药性的关系。结果表明，环孢菌素Ａ（ＣｓＡ）２０，１０μｇ·ｍｌ￣（－１）诱导ＨＬ－６０细胞发生凋亡，而阻断ＨＲ２０细胞于Ｇ＿１期，就不能诱导细胞发生凋亡。低浓度的ＣｓＡ明显增加柔红霉素在ＨＲ２０细胞内的积聚，其逆转抗药性作用与阻断细胞周期运行无关。ＣｓＡ１０μｇ·ｍｌ￣（－１）处理ＨＲ２０细胞，可引起５０ｋＤａ的蛋白质高度磷酸化。结果提示：环孢菌素Ａ阻断抗三尖杉酯碱的ＨＬ－６０细胞于Ｇ＿１期，而诱导敏感的ＨＬ－６０细胞发生凋亡，其阻断作用与抗药性无关     

Needle biopsy of renal allografts: comparison of two techniques

Two techniques for renal allograft biopsy were retrospectively evaluated to compare relative safety and efficacy. After ultrasound (US) localization of the kidney and biopsy with a hand-held 14-gauge cutting needle, an adequate specimen was obtained in 74 of 77 cases (96%). Major complications occurred in six of these 77 cases (8%). One hundred four biopsies were performed by using a smaller 18-gauge cutting needle with a spring-loaded biopsy "gun" and real-time US guidance. With this newer technique, specimens adequate for diagnosis were obtained in 99 biopsies (95%). There was a single major complication with this technique (1%). The 18-gauge needle with real-time US guidance yields comparably adequate specimens with a lower frequency of complications.     

Educating healthcare leaders for the 21st century: evolution not revolution

In April of 1988, the Accrediting Commission on Education for Health Services Administration began reviewing its criteria, policies, and procedures for accreditation. The goal was to update the criteria and revise the policies and procedures to reflect advances in knowledge and practice and to ensure that accreditation judgments are objective and consistent. Since input from those most affected by the new criteria--faculty and practitioners--is essential, the commission sought assistance from the field. Through this collaboration, it is ACEHSA's intention to continue to encourage the dynamic collaboration of the field of education and the field of practice in health services administration that's characteristic of ACEHSA's 20-year history.     

分娩期连续电子胎心监护用于胎儿评估

1背景 在美国，每4例孕妇中有3例在产群中及分娩时使用电子胎儿监护（EFM）（NCHS1993）。1989年，美国妇产科学院（ACOG1989）发表了一项声明，对于低危妊娠既可使用EFM，也可使用间断性胎心听诊；但是，美国预防保健委员会（USPSTF1989）和加拿大的定期健康检查委员会（CTFPHE1994）对高危妊娠仍保留使用EFM。尽管有人对EFM的效果和安全性表示担忧（Thacker 1987：Thacker 1995），
