１．論文：「Factors in genetic susceptibility in a chemical sensitive population using QEESI」、Environ Health Prev Med. 2012 Sep;17(5):357-63
遺伝子：GSTM1、GSTT1、ALDH2、PON1 の４つに限定して分析 日本人を対象にしたことが新規の後追い研究か？
最先端の研究ならば、遺伝子は限定しないはず。
QEESIを使用して "chemical sensitive populations (CSP)." を
定義との要旨の文書があるが、A total of 1,084 employees of Japanese companiesに対してQEESIは実用的？
（二重盲検化学物質負荷試験結果を考慮して）そもそも一般論としてMCSに対してQEESIは実用的なのか？
結論：「Our findings suggest that the common genotypes of GSTM1, GSTT1, ALDH2, and PON1 are of little importance to CSP in a Japanese population」
Environ Health Prev Med. （学会）って、このような論文でも掲載されるのですね。
（超微量）化学物質過敏症と主張する人々は、このような研究の在り方については、問題意識はないのでしょうか？
ブログの記事のみならず、化学物質過敏症の研究の在り方についても着目した方が良いのかもしれない。
ttp://kaken.nii.ac.jp/pdf/2009/seika/jsps-2/31311/19510074seika.pdf によると、２００９年に「日本のMCS患者の診断やスクリーニングに役立つ問診票（QEESI日本語改訂版）が作成できた」とある。
関係論文：「Evaluation of subjective symptoms of Japanese patients with multiple chemical sensitivity using QEESI」、Environ Health Prev Med. 2009 September; 14(5): 267–275
先ず論文の題名が理解できない。題名が「Revision of Japanese QEESI for diagnosis and screening of MCS patients」（ブロークンだなぁ）ならば理解可能か？
AbstractのConclusionsが、「Our results suggest that subjects meeting two out of three subscale criteria can be screened as “patients suffering from a low level of environmental chemicals such as MCS” in Japan」
suggest で良いの？ どんどん読む気が薄れていく。
本文中、Methodsで、「In addition, patients suspected of having psychological disorders were examined by a qualified psychiatrist or practitioner of psychosomatic medicine, and those patients diagnosed with mental health disorders based on DSM-III or ICD-10 were also excluded from the study」
２００９年作成の論文なのにDSM-III（１９８０年改訂）を使うのはなぜ？
化学物質に対する知識に乏しい人やリテラシーに乏しい人は研究から除外しなくて良いのか？
最後に、QEESIを使用してMCSと診断（スクリーニング）した人に対して、
二重盲検化学物質負荷試験をしてQEESIの有効性を確認したとの記述が無いのは、私の見落としなのか？

オーストラリアの Scientific Review Report 「Multiple Chemical Sensitivity: identifying key research needs」
この文書の５ページ：1.1 OVERVIEW 項において、「Presently, a diagnosis of MCS is based commonly on self-reported symptoms and chemical exposure histories. The symptom profile of MCS is indistinguishable from other multi-symptom disorders. No laboratory tests currently exist for diagnosing MCS. Different case definitions and the lack of a characteristic symptom profile and objective laboratory biomarkers for MCS have impeded recognition of the disorder as a distinct clinical entity.」
「There are no standardised treatments for MCS. Current treatments advocated for MCS include dietary changes, nutritional supplements, detoxification and desensitisation techniques, holistic or body therapies, as well as prescription medicines and behavioural therapies. The most common management regime for MCS is avoidance of agents that trigger symptoms.」 の両文は味わい深い。
Current treatmentsの一部はどんなものか想像がつかない。

この文書は労働衛生を指向していて、ネット上での化学物質過敏症論争とは多少話題が違うのかもしれない。治療の話題は含まれないようだ。
②2.Case Definition項の「In February 1996, the invited experts forming a workshop organized by the International Program on Chemical Safety (IPCS) of the WHO, the United Nations Environment Program (UNEP), and the International Labor Organization (ILO) recommended a new name: idiopathic environmental intolerances (IEI) because the term MCS “makes an unsupported judgment on causation” (i.e., environmental chemicals). This concept was taken from Sparks (2000), who defined IEI as a chronic recurrent condition, caused by a person’s inability to tolerate an environmental chemical or a class of exogenous chemicals [23–26]. 」
「IEI, according to the proponents, is a complex gene-environment interaction, whose real cause is not known, for which it is possible—though not always—to identify a triggering event (e.g., sniffing a substance) and a response involving one or more organs or systems. Depending on its characteristics (i.e., the prevalence of somatic or psychological disorders) it can be confused with allergic reactions or psychiatric illness [27, 28]. 」
「However, multiple chemical sensitivities (MCS) is still the term most widely used to describe the complex syndrome; it presents as a chain of symptoms linked to a wide variety of environmental agents and components, at levels normally tolerated by most people [11].」
「The wide range of symptoms with which MCS manifests and the difficulties of differentiating them from other pathologies—immunologic, digestive, cardiac, respiratory, psychiatric, neurologic, endocrine, and so forth—make it hard to develop a diagnostic tool that specifically identifies patients with MCS. The 1999 Consensus Document suggests using the Environmental Exposure and Sensitivity Inventory (EESI) to investigate patients for MCS. The authors subsequently modified this for faster, more widespread use, as the Quick Environmental Exposure and Sensitivity Inventory (QEESI). Some investigators have used the questionnaire in its original form but modified or adapted to take account of geographical differences [3, 33–41].」
これらの文章は味わい深い。
