Kathon® CG reactivity in 1396 consecutively patch tested patients in the Copenhagen area

In 1396 consecutively patch tested patients 18 (1.3%) reacted to Kathon CG. Relevance was established in 4 of the 18 patients. The frequency of positive reactions to Kathon CG in eczema patients seems to have been stable in Denmark during the period 1983 to 1988.     

“Do You Have a Healthy Smile?”

This article examines whether cosmetic interventions by dentists and plastic surgeons are medically indicated and, hence, qualify as medical interventions proper. Cosmetic interventions (and the business strategies used to market them) are often frowned upon by dentists and physicians. However, if those interventions do not qualify as medical interventions proper, they should not be evaluated using medical-ethical norms. On the other hand, if they are to be considered medical practice proper, the medical-ethical principles of nonmaleficence, beneficence, justice and others hold true for cosmetic interventions as much as they do for other medical and dental interventions. It is concluded that most cosmetic interventions do not qualify as medical interventions proper because they do not restore or maintain the patient's health (defined as the patient's integrity) by any objective standards. Rather, cosmetic interventions are intended to enhance a person's physical appearance; more specifically, they intend to fulfill the client's subjective perception of an enhanced appearance.

目的 建立基于UPLC-Q-TOF-MSⁿ的化妆品中40种性激素非法添加分析方法及筛查数据库。方法 色谱柱为Agilent SB-C₁₈(2.1 mm×50 mm,1.8 μm),正离子模式以0.1%甲酸水溶液-乙腈为流动相,负离子模式以水-乙腈为流动相,梯度洗脱,流速0.2 mL·min^-1,柱温35 ℃;采用电喷雾电离源(ESI),采集模式为Scan MS及Targeted MS/MS,将40种性激素的精确质量数、保留时间、二级质谱图导入PCDL软件建立筛查数据库。结果 采用所建立的数据库方法快速筛查100批化妆品,1批育发类产品检出少量黄体酮。结论 本研究所建立的40种性激素分析方法和筛查数据库具有简便、快速、灵敏和准确的特点,适合化妆品中非法添加性激素的高通量筛查和准确定性。     

HPLC同时测定化妆品中22种香豆素类化合物及质谱确证

目的 建立同时测定化妆品中22种香豆素类化合物的HPLC及液相色谱-串联质谱验证方法。方法 采用Agilent Eclipse XDB-Phenyl色谱柱(150mm×4.6mm,3.5μm),流动相为乙腈-0.1%磷酸,梯度洗脱,流速为1.0mL·min^-1,柱温为35℃,检测波长分别为227,310nm。以HPLC结果进行定性筛查,并采用标准曲线法定量,以液相色谱-串联质谱法的结果进行确证。结果 22种香豆素类化合物的线性范围为0.1~10mg·L^-1,相关系数均>0.9993,方法检出浓度为0.1~1.5mg·kg^-1,在低、中、高3种加标水平下,平均回收率为91.4%~114.8%,RSD为0.1%~4.8%。结论 该方法操作简便、准确,适用于膏乳、水剂、粉类及精油类化妆品中22种香豆素类化合物的检测。     

牛角膜混浊和渗透性试验方法与家兔法评价染发类化妆品眼刺激性的比较研究

建立牛角膜混浊和渗透性（bovine corneal opacity and permeability, BCOP）试验,并探讨其用于化妆品眼刺激性评价的预测能力。

选取10种参考化学品进行BCOP试验,并对本实验室日常受理的16件化妆品进行眼刺激性预测。检测受试物暴露后角膜混浊度和荧光素钠渗透性2项参数的变化,计算体外评分值,并与传统动物实验历史数据进行比对分析。

10种已知刺激性分类的参考化学品经BCOP试验测试评价后均被正确分类,得到的分类结果与全球化学品统一分类和标签制度分类结果一致。化妆品的BCOP测试结果显示,BCOP试验对无刺激性样品检测的特异度为80.0%（8/10）,对弱到中刺激的预测灵敏度为83.3%（5/6）,与体内试验比对,总体分类一致性达81.3%（13/16）。

BCOP试验可单独用于识别无危险性分类和具有严重眼损伤或眼刺激性的化学品,在化妆品眼刺激性体外整合测试策略中具有重要的应用价值。

Allergy to 3-nitro-p-hydroxyethylaminophenol and 4-amino-3-nitrophenol in a hair dye

Contact allergy to 3‐nitro‐p‐hydroxyethylaminophenol in a hair dye is described for the first time. p‐Phenylenediamine is the most common screening allergen when allergic contact dermatitis is suspected, but sometimes the allergen is not sufficient for diagnosing allergic contact dermatitis to hair dyes. A 50‐year‐old woman developed a severe scalp dermatitis and developed vesicular hand eczema for the first time in her life. Patch testing was performed with the European Standard Series. The patch testing was supplemented with a local series of cosmetic allergens and the hairdresser's series. At the initial patch testing, there was a + reaction to nickel and a +? to PPD at days 3 and 7. Further, she reacted with a +? to her own hair collected at day 3 after the hair dying which elicited the dermatitis reaction. Open exposure to the product, which had initiated the dermatitis, was negative both before and after the allergic reaction to the product. None of the screening chemicals in the hairdresser's series gave a definite positive reaction. Only by patch testing with the individual hair dye product ingredients, the patient's reactions were explained. The patient gave a positive patch test to 4‐amino‐3‐nitrophenol and 3‐nitro‐p‐hydroxyethylaminophenol at days 3–4 reading.
