The AmRo study: pregnancy outcome in HIV-1-infected women under effective highly active antiretroviral therapy and a policy of vaginal delivery

OBJECTIVE: To explore pregnancy outcome in HIV-1-positive and HIV-negative women, and mother-to-child transmission (MTCT) according to mode of delivery under effective highly active antiretroviral therapy (HAART). DESIGN: Cohort of 143 pregnant HIV-1-infected women including a matched case-control study in a 2:1 ratio of controls to cases (n=98). SETTING: Academic Medical Center in Amsterdam and Erasmus Medical Center in Rotterdam, the Netherlands. POPULATION: Consecutive referred HIV-1 infected pregnant women treated with HAART and matched control not infected pregnant women. MAIN OUTCOME MEASURES: MTCT, preterm delivery, low birthweight, pre-eclampsia. RESULTS: MTCT was 0% (95% CI 0-2.1%). Seventy-eight percent of HIV-1-infected women commenced and 62% completed vaginal delivery. The calculated number of caesarean sections needed to prevent a single MTCT was 131 or more. Preterm delivery rates were 18% (95% CI 11-27) in women infected with HIV-1 and 9% (95% CI 5-13) in controls (P=0.03). HAART used at <13 weeks of gestation was associated with a 44% preterm delivery rate compared with 21% when HAART was started at or after 13 weeks and 14% in controls. (Very) low birthweight and incidence of pre-eclampsia were not different between HIV-1 and controls. CONCLUSIONS: We have not demonstrated any MTCT after vaginal delivery in women effectively treated by HAART. The HAART-associated increase in preterm delivery rate is mainly seen after first trimester HAART use.     

临床输液反应的分析与预防

目的对临床发生的输液反应进行分析,找出发生的原因,探讨预防措施。方法:对30例输液反应资料进行分析。结果:以热原反应最为多见,占76.67%,而过敏反应,占16.67%,局部反应,占6.67%。结论:严格执行消毒制度,遵守无菌操作规程,把好药品和输液器具质量关,合理用药,注意配伍等是减少临床输液反应的关键。     

从“治未病”思想探讨中医药防治EH相关子宫内膜癌的研究意义

子宫内膜癌为女性生殖道三大恶性肿瘤之一。子宫内膜增生症(endometrial hyperplasia,EH)乃子宫内膜癌的癌前病变,因而早期诊断和治疗EH非常必要。中医药防治EH相关子宫内膜癌有其应用简便、价格低廉、有效安全等优势,符合中医"治未病"的思想。由此推理,中医药防治EH相关子宫内膜癌有着广阔前景,值得深入研究。     

乳腺癌改良根治术后皮下积液的预防措施

目的 探讨乳腺癌术后皮下积液的防治方法。方法 回顾北京友谊医院普外科2002年1月～2004年12月收治的女性乳腺癌患者312例。比较皮下引流管接持续高负压吸引组（A组）与持续低负压引流组（B组），乳腺癌改良根治术后皮下积液的发生率。结果 A组160例患者拔管前合计引流量220～350ml，平均270ml。35例发生皮下积液，积液发生率为21．8％。同时伴皮瓣坏死5例。B组152例患者拔管前合计引流量160～250ml，平均180ml。17例发生皮下积液，积液发生率为11．2％。皮瓣坏死3例。B组与A组比较皮下积液发生率有显著性差异（P=0．011）。结论 乳腺癌改良根治术后引流管接持续低负压吸引有助于减少皮下积液的发生率。     

The impact of new screening protocol on individuals at increased risk of colorectal cancer

OBJECTIVE: Screening colonoscopy has been shown to reduce mortality and cancer stage in hereditary nonpolyposis colorectal cancer (HNPCC) individuals. However, the benefit of screening in intermediate risk groups is unknown. The most recent national guidelines have recommended a reduction of screening frequency for the intermediate risk group. Therefore, this study aims to compare the results of colonoscopic screening in HNPCC and intermediate risk groups and assess the effect of the most recent screening protocol recommendations. METHOD: A total of 244 individuals; 108 from HNPCC families (28 mismatch repair gene carriers) and 136 from intermediate risk families were referred for regular colonoscopic screening by the Regional Genetics Service. Findings from 417 colonoscopies performed between 1992 and 2003 were evaluated. RESULTS: A total of three cancers, 39 adenomas and 41 hyperplastic polyps were found in the HNPCC group compared with one cancer, 22 adenomas and 19 hyperplasic polyps in the intermediate risk group. If the recent screening guidelines for the intermediate group were applied, then 89 (44%) fewer colonoscopies would have been performed. Although no cancers would have been missed, six adenomas (mean size = 5.7 mm, range 2-10 mm) with two graded as severely dysplasic and six hyperplastic polyps would not have been detected. CONCLUSION: The detection rate and distribution of adenomas were similar in both groups. If the new colonoscopic screening recommendations for the intermediate risk group had been applied, a small number of significant lesions would have been missed.     

Using stories to battle unintentional injuries: Narratives in safety and health communication

After 14 years of rising death rates due to unintentional injuries in the U.S., it is time to ask how safety messages can be redesigned to have a greater impact on risky behavior. To this end, many researchers have called for a new, narrative approach to prevention messages—based on persuasive stories about people who have suffered injuries and illnesses in the past. Still, there is scant evidence that story-based communications are more effective than equivalent non-narrative messages at changing actual (rather than self-reported) safety and health behavior. Our research examined the impact of injury stories on actual safety behavior in a controlled experimental setting at a US university. Teams of participants assembled a product (a child's swing) using written instructions. The instructions contained safety messages targeting assembly mistakes that have been linked to serious injuries in children who play on swings. Participant teams were randomly assigned to three conditions: assembly instructions containing story-based safety messages, instructions with concrete (but non-anecdotal) safety messages, and instructions with traditional abstract safety messages. After adjustment for covariates, story-based messages resulted in a 19 percent improvement in safety behavior, compared with non-narrative communications. Importantly, injury stories did not create undue fear of the message object, demonstrating that brief anecdotes about accident victims can convince people to take reasonable precautions without creating unwarranted alarm about risks.     

异位妊娠259例临床总结分析

目的探讨异位妊娠的发病相关因素,提出防治措施。方法对我院10年间收治的259例异位妊娠病例的发病趋势,既往病史及节育状况、误诊情况作一回顾分析。结果近10年异位妊娠发生率为2.19%并呈上升趋势。人工流产、节育手术、下腹部手术等与异位妊娠的发生关系密切。结论降低人工流产率,减少性病传播是预防异位妊娠发生的重要手段,随着高科技手段的应用使异位妊娠早期准确的诊断成为可能,为保守治疗赢得机会。
