Threshold for occluded formaldehyde patch test in formaldehyde-sensitive patients

Our purpose was to investigate the eliciting threshold concentration of formaldehyde in formaldehyde-sensitive individuals in the occluded and non-occluded patch teat and to evaluate the relationship in repeated open application test (ROAT) with a product containing a formaldehyde releaser. 20 formaldehyde-sensitive patients and a control group of 20 healthy volunteer were included in the study. Occluded and non-occluded patch tests with formaldehyde solutions form 25 to 10,000 ppm. and ROAT for I week with a leave-on cosmetic product containing on average 300 ppm formaldehyde. Were carried out simultaneously on each subject. In the occluded patch test. 1/2 of the 20 patients only reacted to 10,000 ppm formaldehyde. 9 reacted to 5,000 ppm. 3 reacted to 1.000 ppm. 2 reacted to 500 ppm and I reacted to 25 ppm. No definite positive reactions were observed in the non-occluded patch test or in the ROAT No positive reactions were observed in the control group to any of the test procedures. We concluded that the threshold concentration for occluded patch test to formaldehyde in formaldehyde-sensitive patients was 250 ppm. The threshold in occluded patch test corresponded to the degree of sensitivity Definite positive reactions in the ROAT were not seen, either indicating that they are unlikely to happen with the type of product used or that the exposure time was too short.     

临床护理路径在臀肌挛缩症患者健康教育中的应用

目的 探讨应用临床护理路径对臀肌孪缩症患者健康教育的效果。方法 将60例臀肌挛缩症患者分为对照组（n=30）和实验组（n=30），对照组采用常规教育方法，实验组按制定好的健康教育路径进行教育，将两组患者的健康教育达标率、对护理工作的满意度进行比较。结果 两组患者在健康教育达标率、对护理工作的满意度方面比较，差异有统计学意义（P〈0．01）。结论 对臀肌挛缩症患者运用护理手段进行健康教育后提高了患者的健康教育达标率，提高了护理工作的满意度，效果优于常规教育方法。     

放射性核素敷贴疗法在慢性局限性湿疹治疗中的应用

目的 观察放射性核素敷贴疗法对慢性局限性湿疹的治疗作用，并探讨影响疗效的因素。方法 对179例慢性局限性湿疹患按不同病程、不同性别进行分组，均采用相同的放射性核素敷贴治疗，并以同一疗效标准判定其治疗效果。随访1～4a，观察复发情况。结果 病程不同组间、性别不同组间疗效无显差异，但性别不同，复发率存在显差异性，且女性复发率明显高于男性。结论 放射性核素敷贴疗法是治疗慢性局限性湿疹的有效、安全、低复发率、无痛苦的治疗方法。     

应用QQC活动提高儿科静脉穿刺成功率

目的提高静脉穿刺成功率，减少患儿因反复穿刺造成的痛苦及恐惧，减轻家长因担心穿刺困难而产生的焦虑，提高治疗和抢救的效率。方法详细介绍了QQC活动在提高儿科静脉穿刺成功率的应用，包括找出目前存在的问题，确定目标、采用流程图的方法分析问题存在的原因，制定相应的质量改进方案，并测量实施结果。结果实施QQC活动后静脉穿刺成功率比实施前明显提高。结论有效的QQC活动可以提高静脉穿刺成功率。

成分输血在临床中的应用

成分输血是现代输血学的重要标志之一。临床医生要了解成分输血的知识,遵循科学用血、合理用血、节约用血的原则,根据病情有针对性地开展成分输血。成分输血的重点,应当是血液的有形成分,即以红细胞和血小板为主的成分输血。本文就成分输血的特点与临床应用等有关问题进行综述。     

国产长效皮下埋植避孕剂的临床应用

1992年我院用国产长效皮下埋植避孕剂(左旋18-甲基炔诺酮),对600例育龄妇女进行皮下埋植,经1年随访,结果显示:国产长效皮下埋植剂的避孕效果达100％。600例中10例因出现月经异常而终止使用,其持续使用率为98.33％,获得了与进口长效皮下埋植避孕剂相同的效果。     

Food-induced contact urticaria syndrome (CUS) in atopic dermatitis: reproducibility of repeated and duplicate testing with a skin provocation test, the skin application food test (SAFT)

IgE-mediated contact urticaria syndrome (CUS) is one of the manifestations of allergy in childhood atopic dermatitis (AD). Allergens such as foods and animal products penetrate the skin easily. They can then cause urticarial reactions in sensitized individuals. A provocation test system for foods, called the skin application food test (SAFT), has been developed. Over more than 5 years, a group of 175 patients with AD was built-up and investigated in a prospective follow-up study with SAFT. SAFT was more frequently positive in AD children aged 6–2 years than in older children. In several children of this population (Group 1), we repeated SAFT within a period of 1 year. In another unrelated group of children (Group 2–1), we compared the results of 'original' SAFT and SAFT using square chambers (Van der Bend) or Silver patches. In the 3rd group (Group 2–2) we compared'original' SAFT with SAFT using big Finn Chambers. The agreement between the tests was high: in Group 1, we observed 88 to 93% concordant scores, and in Group 2, the scores were 96% to 100%. Statistically, the K coefficient ranged from 0.71–0.87 in Group 1, and from 0.83–1.00 in Group 2. SAFT is therefore highly reproducible. Agreement was at least 88% between the scores (the lowest K value observed was at least 0.71).
