MCS – Multiple Chemical Sensitivity recognized as physical disease at ICD-10 in Japan

Website of Citizens Against Chemicals Pollution (CACP) Japan

Eva Caballé “Eva’s No Fun Blogspot“ from Spain reports:

Few days ago I discovered that my blog had some visitors from this Japanese website, a blog done by Prof. Masumi Yamamuro of Tokyo University. When I read this post, I discovered that it was my article “The Naked Truth about MCS” in Japanese and they mentioned that it had been translated by Citizens Against Chemicals Pollution (CACP) and I decided to write them. Takeshi Yasuma, from Citizens Against Chemicals Pollution (CACP), explained me that he found my article at The Canary Report and he immediately translated it into Japanese with the subtitle “Cry of Spanish MCS Patient’s Heart”, because he was very impressed by it. He published the Japanese version of my article in Citizens Against Chemicals Pollution website last August and also in the September issue of their monthly newsletter.

I also asked him about MCS situation in Japan, and now, with his permission, I post the part of his email where he explained it and I also reprint CACP’s mission.

There is good news.

On October 1, 2009, the Medical Information System Development Center (MEDIS-DC), a subsidiary organization of Ministry of Health, Labor and Welfare (MHLW) published the revised list of ICD-10 Japanese Standard Disease Code Master in which MCS is categorized in T65.9: Toxic effect of other and unspecified substances / Toxic effect of unspecified substance.

It has been now clearly recognized in Japan that MCS is NOT a mental disease but a physical disease.

This decision is welcomed by MCS patients and their supporters and they expect the possible coverage of MCS by health insurance, but so far it remains uncertain whether or how it will change.

Patients and their supporters will take actions for calling on Japanese government to give urgent supports for MCS patients including coverage of MCS by health insurance, strengthening medical services, financial support for livelihood and provision of safer houses.

On October 31 at Tokyo, we will hold a MCS symposium celebrating the recognition and calling on Japanese government to take further measures for MCS.

CACP’s Mission:

To provide information to the public and take action necessary for protecting human health and environment from harmful chemicals based on Precautionary Principle and Environmental Justice.

Main Activities:

  • To issue monthly newsletter [PICO].
  • To issue weekly mail service.
  • To provide information at our website.
  • To publish books and booklets related to environmental health.
  • To propose our policies to the Japanese Government and local governments.
  • To hold seminars for citizens on protecting human health and environment.

I want to thank to Takeshi Yasuma for translating my article, for letting me publish all this information about MCS in Japan and also for asking me to write a message to MCS patients and their supporters to be presented at the MCS symposium. It will be an honour to me!

Air Pollution Adversely Affects Olfactory Function and Intranasal Trigeminal Sensitivity

Air Pollution in Mexico City

Surprisingly little is known about the effects of big-city air pollution on olfactory function and even less about its effects on the intranasal trigeminal system, which elicits sensations like burning, stinging, pungent, or fresh and contributes to the overall chemosensory experience. 

Using the Sniffin’ Sticks olfactory test battery and an established test for intranasal trigeminal perception, we compared the olfactory performance and trigeminal sensitivity of residents of Mexico City, a region with high air pollution, with the performance of a control population from the Mexican state of Tlaxcala, a geographically comparable but less polluted region. 

We compared the ability of 30 young adults from each location to detect a rose-like odor (2-phenyl ethanol), to discriminate between different odorants, and to identify several other common odorants. The control subjects from Tlaxcala detected 2-phenyl ethanol at significantly lower concentrations than the Mexico City subjects, they could discriminate between odorants significantly better, and they performed significantly better in the test of trigeminal sensitivity. 

We conclude that Mexico City air pollution impairs olfactory function and intranasal trigeminal sensitivity, even in otherwise healthy young adults.

Brain dysfunction in MCS – Multiple Chemical Sensitivity

Doctor examining brain Scan

The aim of  the following study was to ascertain whether MCS patients present brain single photon emission computed tomography (SPECT) and psychometric scale changes after a chemical challenge.

This procedure was performed with chemical products at non-toxic concentrations in 8 patients diagnosed with MCS and in their healthy controls. In comparison to controls, cases presented basal brain SPECT hypoperfusion in small cortical areas of the right parietal and both temporal and fronto-orbital lobes.

After chemical challenge, cases showed hypoperfusion in the olfactory, right and left hippocampus, right parahippocampus, right amygdala, right thalamus, right and left Rolandic and right temporal cortex regions(p</=0.01). By contrast, controls showed hyperperfusion in the cingulus, right parahippocampus, left thalamus and some cortex regions (p</=0.01). The clustered deactivation pattern in cases was stronger than in controls (p=0.012) and the clustered activation pattern in controls was higher than in cases (p=0.012).

In comparison to controls, cases presented poorer quality of life and neurocognitive function at baseline, and neurocognitive worsening after chemical exposure. Chemical exposure caused neurocognitive impairment, and SPECT brain dysfunction particularly in odor-processing areas, thereby suggesting a neurogenic origin of MCS.

Autism – Do terbutaline- and mold-associated impairments of the brain and lung relate to autism?

Autism - Cute little Boy living in his own world

Increased prevalence of the autism spectrum disorders (ASD) and the failure to find genetic explanations has pushed the hunt for environmental causes. These disorders are defined clinically but lack objective characterization.

 To meet this need, we measured neurobehavioral and pulmonary functions in eight ASD boys aged 8 to 19 years diagnosed clinically and compared them to 145 unaffected children from a community with no known chemical exposures. As 6 of 35 consecutive mold/ mycotoxin (mold)-exposed children aged 5 to 13 years had ASD, we compared them to the 29 non-ASD mold-exposed children, and to the eight ASD boys. Comparisons were adjusted for age, height, weight, and grade attained in school. 

The eight ASD boys averaged 6.8 abnormalities compared to 1.0 in community control boys. The six mold-exposed ASD children averaged 12.2 abnormalities. The most frequent abnormality in both groups was balance, followed by visual field quadrants, and then prolonged blink reflex latency. 

Neuropsychological abnormalities were more frequent in mold-exposed than in terbutaline-exposed children and included digit symbol substitution, peg placement, fingertip number writing errors, and picture completion. Profile of mood status scores averaged 26.8 in terbutaline-exposed, 52 in mold exposed, and 26 in unexposed. The mean frequencies of 35 symptoms were 4.7 in terbutaline, 5.4 in mold/ mycotoxins exposed and 1.7 in community controls.

Patients with indoor exposure to molds compared to patients exposed to chemicals

Protection against molds

Neurobehavioral and pulmonary impairment in 105 adults with indoor exposure to molds compared to 100 exposed to chemicals 

Patients exposed at home to molds and mycotoxins and those exposed to chemicals (CE) have many similar symptoms of eye, nose, and throat irritation and poor memory, concentration, and other neurobehavioral dysfunctions. Aim of a study was to compare the neurobehavioral and pulmonary impairments associated with indoor exposures to mold and to chemicals. 

105 consecutive adults exposed to molds (ME) indoors at home and 100 patients exposed to other chemicals were compared to 202 community referents without mold or chemical exposure. To assess brain functions, the scientists measured 26 neurobehavioral functions. Medical and exposure histories, mood states score, and symptoms frequencies were obtained. Vital capacity and flows were measured by spirometry. Groups were compared by analysis of variance (ANOVA) after adjusting for age, educational attainment, and sex, by calculating predicted values (observed/predicted x 100 = % predicted). And p < .05 indicated statistical significance for total abnormalities, and test scores that were outside the confidence limits of the mean of the percentage predicted. 

People exposed to mold had a total of 6.1 abnormalities and those exposed to chemicals had 7.1 compared to 1.2 abnormalities in referents. Compared to referents, the exposed groups had balance decreased, longer reaction times, and blink reflex latentcies lengthened. Also, colour discrimination errors were increased and visual field performances and grip strengths were reduced. The cognitive and memory performance measures were abnormal in both exposed groups. Culture Fair scores, digit symbol substitution, immediate and delayed verbal recall, picture completion, and information were reduced. Times for peg-placement and trail making A and B were increased. 

One difference was that chemically exposed patients had excess fingertip number writing errors, but the mold-exposed did not. Mood State scores and symptom frequencies were greater in both exposed groups than in referents. Vital capacities were reduced in both groups. Neurobehavioral and pulmonary impairments associated with exposures to indoor molds and mycotoxins were not different from those with various chemical exposures.
