Late Effects of Childhood Acute Leukemia and Its Treatment

Late effects of childhood acute leukemia and its treatment were studied in 766 patients (684 ALL, 73 ANLL, and 9 others) in Japan who had remained in remission for more than 1 year after their first complete remission. Delayed adverse sequelae involve a wide variety of organs and their functions. Short stature was present in 2.61%, obesity in 3.79%, abnormalities of growth hormone secretion in 1.5%, delayed secondary sex characteristics in 1.5% of males and 0.6% of females, motor disturbances in 1.17%, sensory disturbances in 0.91%, intellectual and learning disabilities in 2.48%, abnormal findings in routine neurologic examinations in 1.31%, EEG abnormalities in 4.30%, brain CT abnormalities in 5.09% and cardiac dysfunction in 1.07%. Various other disorders were seen in 20 patients. Many of these delayed adverse sequelae are caused by or related to central nervous system prophylaxis and systemic combination chemotherapy. The results suggest that it is needed to improve therapeutic methods through the stratification of patients by risk factors and detailed analysis of prognostic factors. Moreover it is important to render medical and psychosocial support to long-term survivors of childhood leukemia through interactions between the patient, parents and medical staff.     

不同针刺手法调节体温效应机制研究概况

目的:介绍近年不同的针刺手法对体表温度调节效应的研究,并探讨其产生体温效应的机制。方法:从临床研究、实验研究等方面进行综述。结论:针刺穴位的作用及其疗效,随着手法引起的温度变化而不同,针刺补法引起体温升高,而泻法则引起体温下降。体表温度是由血液循环状态、交感神经兴奋程度和组织新陈代谢状态等多方面决定的,不同的针刺手法引起的皮肤温度变化与影响上述3个环节状态有关。

茶氨酸对脑缺血再灌注损伤保护作用的实验研究

目的观察茶氨酸对脑缺血再灌注损伤的保护作用,为临床脑缺血再灌注损伤的预防和治疗提供实验依据。方法将24只健康家兔随机分为四组：假手术组、脑缺血组、茶氨酸予处理组和茶氨酸治疗组。麻醉后分离血管,采用基底动脉、双侧颈总动脉结扎法制备急性全脑缺血再灌注动物模型。假手术组仅分离动脉不结扎,予处理组在缺血前应用茶氨酸,治疗组在缺血后应用茶氨酸,缺血组不作特殊药物处理。各组分别在规定时间点即缺血前、再灌注后30min、1h、2h采血测定神经特异性烯醇化酶(NSE)含量,取脑组织活检观察超微结构,处死动物测定脑含水量。结果茶氨酸予处理组和治疗组以上各项指标均较脑缺血组有显著的改善,提示茶氨酸具有神经保护作用。实验还显示茶氨酸予处理组在再灌注30min时NSE含量与假手术组比较无差异,提示用茶氨酸予处理后可能使缺血后脑损害的发生延迟,为进一步的治疗争取了宝贵时间。结论茶氨酸对脑缺血再灌注损伤有保护作用,值得进一步研究。     

Efficacy and functionality of silver-coated textiles in patients with atopic eczema

BACKGROUND: Microbial skin colonization with Staphylococcus aureus is known to play an important role in atopic eczema (AE). Recently, an antibacterial effect of silver-coated textiles on S. aureus colonization has been demonstrated. OBJECTIVES: To investigate clinical efficacy and functionality of silver-coated textiles in AE, a multicentre, double-blind, placebo-controlled trial was conducted. PATIENTS/METHODS: From November 2001 to August 2002, 68 consecutive outpatients clinically diagnosed with generalized AE were included in the study. Inclusion criteria were the clinical diagnosis of AE with a moderate severity as measured by the scoring of atopic dermatitis (SCORAD) index with at least 20. Patients were instructed to wear either silver-coated (verum, 35 patients + 2 dropouts) or cotton garments (placebo, 22 patients + 9 dropouts) directly on the skin for 2 weeks. Only basic skin care and ongoing therapy with topical steroids or oral antihistamines was permitted. Clinical severity was assessed using the 'SCORAD' before, during and at the end of study. Quality of life (QOL), wearing comfort (WC) and functionality (FU) of study clothes were measured in parallel. Patients documented their subjective and objective symptoms daily. RESULTS: In the verum group, eczema improved significantly after 1 week with further enhancement until the end of study (P = 0.03 and P < 0.001). Silver-coated textiles were comparable to cotton in WC and FU. Pruritus and self-assigned skin condition improved significantly more than with placebo (P < 0.001 and P = 0.003). CONCLUSIONS: In conclusion, silver-coated textiles are able to improve objective and subjective symptoms of AE significantly within 2 weeks, showing a good wearing comfort and functionality comparable to cotton.

An Evaluation of the Residual Activity of Antiseptic Handrub Lotions: An ‘In Use’ Setting Study

An evaluation of the residual activity of quick-drying agents (alcoholic solutions) used for hygienic hand disinfection is described. We looked for residual efficacy following hand disinfection with soap and water alone or followed by one of two alcoholic handrub lotions supplied from an automatic hand washing machine. The bacterial counts on the hands obtained before and within 2 successive hours after disinfection showed that alcoholic chlorhexidine was the most effective for 10 minutes after contamination of the hands. WELPAS® (alcoholic chlorbenzarconium) followed this in its immediate effect and was better than soap and water alone. There were no significant differences after 30‘ or 120‘ between the three disinfecting methods.
