Illness experience in fibromyalgia syndrome: A metasynthesis of qualitative studies.

Primary Care Musculoskeletal Research Centre, Keele University, Keele, Staffordshire ST5 5BG, United Kingdom.

There is growing interest in synthesizing qualitative research. Despite certain philosophical and methodological difficulties, such syntheses are potentially useful in enriching the insights of empirical qualitative work in a particular area. This paper reports an interpretive review of research into the subjective experience of fibromyalgia syndrome (FMS), utilizing principles of metasynthesis. Twenty-three separate studies were identified. Each study was evaluated using methodological criteria to provide a context for interpretation of substantive findings. Principal findings were extracted and synthesized under four broad categories: experience of symptoms, search for diagnosis, legitimacy, and coping. Our findings re-emphasised the point that pain in FMS is ambiguous and invisible, raising questions of credibility and legitimacy. People with a diagnosis of FMS appear to frame the experience of symptoms within the biomedical model, where FMS is viewed as an organic entity potentially identifiable through biomedical tests. The subjective meaning and perceived legitimacy of the diagnostic label appear to be important factors in the subjective experience of FMS. Coping strategies adopted can be subsumed under Mannerkorpi, K., Kroksmark, T., Ekdahl, C. [1999. How patients with fibromyalgia experience their symptoms in everyday life. Physiotherapy Research International, 4(2), 110-122.] notions of 'struggling', 'adapting', 'in despair' and 'giving up'. Most studies had at least one identified methodological shortcoming, though it is not straightforward to identify the significance of such shortcomings. We conclude that there is scope for further research into the subjective experience of FMS, and into the methodology of metasynthesis, especially in relation to methodological appraisal.

Allergens Retained in Clothing

Allergens Retained in Clothing

Susan Nedorost; Margaret Kessler; Thomas McCormick

Dermatitis.  2007;18(4):212-214

Abstract

Background: Some patients state compliance with avoidance of identified allergens, yet have persistent dermatitis in areas under tight-fitting clothing.
Objective: To analyze a series of such cases to identify allergens most likely retained in clothing.
Methods: Review of contact dermatitis clinic cases and identification of type and formula weight of allergens involved.
Results: High-formula-weight allergens and allergens present in medicament ointments are difficult to dissolve in laundry detergent and water and may be retained in clothing.
Conclusion: Retention of allergens in clothing, even after washing, may explain recalcitrant dermatitis in a patient who states compliance with avoidance of a seemingly relevant allergen. Dermatologists should consider the possibility of allergen retention in clothing whenever a patient has only partial clearing after at least 1 month of attempted compliance with avoidance of identified allergens. Purchase of new clothing may be required to clear allergic contact dermatitis in this situation.

Electronic support groups, patient-consumers, and medicalization: the case of contested illness.

Electronic support groups, patient-consumers, and medicalization: the case of contested illness.

http://www.ncbi.nlm.nih.gov/pubmed/18418983?dopt=AbstractPlus

Department of Sociology, Oregon State University, Corvallis, OR 97331, USA. kristin.barker@oregonstate.edu

This article illustrates the role electronic support groups play in consumer-driven medicalization. The analysis is based on an observational study of a year in the life of an electronic support group for sufferers of the contested illness fibromyalgia syndrome. The analysis builds on and extends scholarship concerning the growing influence of lay expertise in the context of medical uncertainty by showing how the dominant beliefs and routine practices of this electronic community simultaneously (and paradoxically) challenge the expertise of physicians and encourage the expansion of medicine's jurisdiction. Drawing on their shared embodied expertise, participants confirm the medical character of their problem and its remedy, and they empower each other to search for physicians who will recognize and treat their condition accordingly. Physician compliance is introduced as a useful concept for understanding the relationship between lay expertise, patient-consumer demand, and contemporary (and future) instances of medicalization.

Chronic fatigue syndrome in male gulf war veterans and civilians: a further test of the single syndrome hypothesis.

http://www.ncbi.nlm.nih.gov/pubmed/18420761?dopt=AbstractPlus

UMDNJ-New Jersey Medical School, USA. donald.ciccone@va.gov.

Different modes of fatigue onset in male Gulf War veterans versus male civilians raise the possibility that chronic fatigue syndrome (CFS) may not be a single disease entity. We addressed this issue by comparing 45 male veterans with CFS to 84 male civilians who satisfied identical case criteria. All were evaluated for fibromyalgia (FM), multiple chemical sensitivity and psychiatric comorbidity. CFS was more likely to present in a sudden flu-like manner in civilians than veterans (p < .01) and comorbid FM was more prevalent in civilians (p < .01). These findings question the assumption that all patients with CFS suffer from the same underlying disorder.

Abstract
Objectives: The aim of this prospective study was to investigate whether occupational pesticide exposure during pregnancy causes adverse effects on the reproductive development in the male infants.

Design and measurements: Pregnant women employed in greenhouses in Denmark were consecutively recruited, and 113 mother–son pairs were included. The mothers were categorized as occupationally exposed (91 sons) or unexposed (22 sons) to pesticides during pregnancy. Testicular position and volume, penile length, and position of urethral opening were determined at 3 months of age using standardized techniques. Concentrations of reproductive hormones in serum from the boys were analyzed.

Results: The prevalence of cryptorchidism at 3 months of age was 6.2% [95% confidence interval (CI) , 3.0–12.4]. This prevalence was considerably higher than among Danish boys born in the Copenhagen area (1.9% ; 95% CI, 1.2–3.0) examined by the same procedure. Boys of pesticide-exposed mothers showed decreased penile length, testicular volume, serum concentrations of testosterone, and inhibin B. Serum concentrations of sex hormone-binding globulin, follicle-stimulating hormone, and the luteinizing hormone:testosterone ratio were increased compared with boys of nonexposed mothers. For individual parameters, only the decreased penile length was statistically significant (p = 0.04) . However, all observed effects were in the anticipated direction, and a joint multivariate test showed that this finding had a p-value of 0.012.

Conclusions: Our findings suggest an adverse effect of maternal occupational pesticide exposure on reproductive development in the sons despite current greenhouse safeguards and special measures to protect pregnant women.

Abstract
Background: Maternal exposure to wood fuel smoke may lead to impaired fetal growth due to hypoxia and or oxidative stress from smoke constituents such as carbon monoxide and particulate matter.

Objectives: We studied the risk of low birth weight (LBW) and reduced mean birth weight in relation to reported use of wood for cooking during the prenatal period, compared with natural gas (NG) .

Methods: We studied a historical cohort of women who had a singleton live birth in the years 2000–2002, from a semirural area of Pakistan. Infant's birth weight was obtained from records, and prenatal records had data for maternal body mass index and parity. Cooking habits, daytime sleep habits, and type of fuel used during the pregnancies in 2000–2002 were ascertained by a survey done in 2004–2005. We performed multiple linear and logistic regression modeling using propensity scores to adjust for confounding variables.

Results: Unadjusted mean (± SD) birth weight was 2.78 ± 0.45 kg in wood users, and 2.84 ± 0.43 kg (p < 0.06) in NG users. Infants born to wood users averaged 82 g lighter than infants born to NG users when weight was adjusted for confounders (p < 0.07) . The rate of LBW (< 2,500 g) was 22.7% among wood users compared with 15.0% in NG users (p < 0.01) , for an adjusted relative risk of 1.64 (95% confidence interval, 1.10–2.34) . The population attributable risk for LBW explained by wood use was estimated to be 24%.

Conclusion: Cooking with wood fuel during pregnancy, a potentially modifiable exposure, was associated with LBW and marginally lower mean birth weight compared with using NG.

Abstract
Background: Although patients with heart failure (HF) have been identified as particularly susceptible to the acute effects of air pollution, the effects of long-term exposure to air pollution on patients with this increasingly prevalent disease are largely unknown.

Objective: This study was designed to examine the mortality risk associated with residential exposure to traffic-related air pollution among HF patients.

Methods: A total of 1,389 patients hospitalized with acute HF in greater Worcester, Massachusetts, during 2000 were followed for survival through December 2005. We used daily traffic within 100 and 300 m of residence as well as the distance from residence to major roadways and to bus routes as proxies for residential exposure to traffic-related air pollution. We assessed mortality risks for each exposure variable using Cox proportional hazards models adjusted for prognostic factors.

Results: After the 5-year follow-up, only 334 (24%) subjects were still alive. An interquartile range increase in daily traffic within 100 m of home was associated with a mortality hazard ratio (HR) of 1.15 [95% confidence interval (CI) , 1.05–1.25], whereas for traffic within 300 m this association was 1.09 (95% CI, 1.01–1.19) . The mortality risk decreased with increasing distance to bus routes (HR = 0.88 ; 95% CI, 0.81–0.96) and was larger for those living within 100 m of a major roadway or 50 m of a bus route (HR = 1.30 ; 95% CI, 1.13–1.49) . Adjustment for area-based income and educational level slightly attenuated these associations.

Conclusions: Residential exposure to traffic-related air pollution increases the mortality risk after hospitalization with acute HF. Reducing exposure to traffic-related emissions may improve the long-term prognosis of HF patients.

Altered cortical excitability in subjectively electrosensitive patients: results of a pilot study.

http://www.ncbi.nlm.nih.gov/sites/entrez/17324677

Department of Psychiatry, Psychosomatics, and Psychotherapy, University of Regensburg, Regensburg, Germany.

OBJECTIVE: Hypersensitivity to electromagnetic fields is frequently claimed to be linked to a variety of unspecific somatic and/or neuropsychological complaints. Whereas provocation studies often failed to demonstrate a causal relationship between electromagnetic field exposure and symptom formation, neurophysiological examinations highlight baseline deviations in people claiming to be electrosensitive. METHODS: To elucidate a potential role of dysfunctional cortical regulations in mediating hypersensitivity to electromagnetic fields, cortical excitability parameters were measured by transcranial magnetic stimulation in subjectively electrosensitive patients (n=23) and two control groups (n=49) differing in their level of unspecific health complaints. RESULTS: Electrosensitive patients showed reduced intracortical facilitation as compared to both control groups, while motor thresholds and intracortical inhibition were unaffected. CONCLUSIONS: This pilot study gives additional evidence that altered central nervous system function may account for symptom manifestation in subjectively electrosensitive patients as has been postulated for several chronic multisymptom illnesses sharing a similar clustering of symptoms.

Green product seals are gray area

As Earth Day 2008 arrives on Tuesday, American consumers face a renewed outpouring of environmental marketing claims - boasts by companies that their products are everything from "100 percent natural" to "recyclable," "eco-friendly," "sustainable," "biodegradable," or just plain "green."

Occupational contact dermatitis due to essential oils.

http://www.ncbi.nlm.nih.gov/pubmed/18416758?dopt=AbstractPlus

Department of Dermatology, Rabin Medical Center, Beilinson Campus, Petah Tiqwa, Israel. atrattner@clalit.org.il

BACKGROUND: Allergic contact dermatitis induced by the occupational use of products containing essential oils has not been studied comprehensively. OBJECTIVES: The aim of the present report was to describe the characteristics, diagnosis, and outcome of 5 patients with occupational contact dermatitis because of essential oils attending our outpatient dermatology clinics over a 2-year period. PATIENTS: These patients are added to the 11 cases reported thus far in the literature. RESULTS: The research shows that for proper diagnosis, patch tests with the standard series and the fragrance series should be performed, in addition to tests with the specific oils to which the patients were exposed. CONCLUSIONS: Patients should be instructed to avoid the allergens identified. Sensitization to essential oils has important implications for the occupational future of affected individuals.

Implication of Xenobiotic Metabolizing Enzyme gene (CYP2E1, CYP2C19, CYP2D6, mEH and NAT2) Polymorphisms in Breast Carcinoma.

Comment:  I take it that this would put others who are slow acetylators at greater risk of cancer.  That would be an interesting study to perform... correlates of MCS and cancer. 
 
Implication of Xenobiotic Metabolizing Enzyme gene (CYP2E1, CYP2C19, CYP2D6, mEH and NAT2) Polymorphisms in Breast Carcinoma.
Xenobiotic Metabolizing Enzymes (XMEs) contribute to the detoxification of numerous cancer therapy-induced products. This study investigated the susceptibility and prognostic implications of the CYP2E1, CYP2C19, CYP2D6, mEH and NAT2 gene polymorphisms in breast carcinoma patients.

Methods: The authors used polymerase chain reaction and restriction enzyme digestion to characterize the variation of the CYP2E1, CYP2C19, CYP2D6, mEH and NAT2 gene in a total of 560 unrelated subjects (246 controls and 314 patients).

Results: The mEH (C/C) mutant and the NAT2 slow acetylator genotypes were significantly associated with breast carcinoma risk (p = 0.02; p = 0.01, respectively).

For NAT2 the association was more pronounced among postmenopausal patients (p = 0.006). A significant association was found between CYP2D6 (G/G) wild type and breast carcinoma risk only in postmenopausal patients (p = 0.04).

Association studies of genetic markers with the rates of breast carcinoma specific overall survival (OVS) and the disease-free survival (DFS) revealed among all breast carcinoma patients no association to DFS but significant differences in OVS only with the mEH gene polymorphisms (p = 0.02). In addition, the mEH wild genotype showed a significant association with decreased OVS in patients with axillary lymph node-negative patients (p = 0.03) and with decreasesd DFS in patients with axillary lymph node-positive patients (p = 0.001).

However, the NAT2 intermediate acetylator genotype was associated with decreased DFS in axillary lymph node-negative patients.

Conclusion: The present study may prove that polymorphisms of some XME genes may predict the onset of breast carcinoma as well as survival after treatment.

Different modes of fatigue onset in male Gulf War veterans versus male civilians raise the possibility that chronic fatigue syndrome (CFS) may not be a single disease entity. We addressed this issue by comparing 45 male veterans with CFS to 84 male civilians who satisfied identical case criteria. All were evaluated for fibromyalgia (FM), multiple chemical sensitivity and psychiatric comorbidity. CFS was more likely to present in a sudden flu-like manner in civilians than veterans (p < .01) and comorbid FM was more prevalent in civilians (p < .01). These findings question the assumption that all patients with CFS suffer from the same underlying disorder.

Prevalence and risk factors for chemical sensitivity and sensory hyperreactivity in teenagers.

http://www.ncbi.nlm.nih.gov/pubmed/18403259?dopt=AbstractPlus

Department of Psychology, Umeå University, Umeå, Sweden.

The prevalence of chemical sensitivity (CS) and sensory hyperreactivity (SHR) was assessed in a teenage population. Among a random sample of 401 teenagers, 326 (81.3%) answered questionnaires assessing sensitivity to chemicals and noise, anxiety and depression. A subgroup of 85 teenagers conducted a capsaicin inhalation test. The estimated prevalence was 15.6% for general self-reported CS, 3.7% for CS with affective and behavioral consequences, about 1% for SHR. Sensitivity variables were positively intercorrelated. Risk factors for general CS were noise sensitivity (OR: 2.1), probable anxiety (OR: 2.5) and female sex (OR: 2.0). CS problems seem to be present also in teenagers, although less so than in adults. Furthermore, CS seems to be related to other environmental sensitivities.

Neurodevelopmental Disorders, Maternal Rh-Negativity, and Rho(D) Immune Globulins: A Multi-Center Assessment.

In English, this study found a correlation between receiving thimerosal in vaccines and some neurodevelopmental disorders.

Neurodevelopmental Disorders, Maternal Rh-Negativity, and Rho(D) Immune Globulins: A Multi-Center Assessment.

http://www.ncbi.nlm.nih.gov/pubmed/18404135?dopt=AbstractPlus

The Institute of Chronic Illnesses, Inc., Silver Spring, MD 20905, USA. mgeier@comcast.net.

BACKGROUND: Many formulations of Thimerosal (49.55% mercury by weight)-containing Rho(D) immune globulins (TCRs) were routinely administered to Rh-negative mothers in the US prior to 2002. OBJECTIVES: It was hypothesized: (1) if prenatal Rho(D)-immune globulin preparation exposure was a risk factor for neurodevelopmental disorders (NDs) then more children with NDs would have Rh-negative mothers compared to controls; and (2) if Thimerosal in the Rho(D)-immune globulin preparations was the ingredient associated with NDs, following the removal of Thimerosal from all manufactured Rho(D)-immune globulin preparations from 2002 in the US the frequency of maternal Rh-negativity among children with NDs should be similar to control populations. METHODS: Maternal Rh-negativity was assessed at two sites (Clinic A-Lynchburg, VA; Clinic B-Rockville and Baltimore, MD) among 298 Caucasian children with NDs and known Rh-status. As controls, maternal Rh-negativity frequency was determined from 124 Caucasian children (born 1987-2001) without NDs at Clinic A, and the Rh-negativity frequency was determined from 1,021 Caucasian pregnant mothers that presented for prenatal genetic care at Clinic B (1980-1989). Additionally, 22 Caucasian patients with NDs born from 2002 onwards (Clinics A and B) were assessed for maternal Rh-negativity. RESULTS: There were significant and comparable increases in maternal Rh-negativity among children with NDs (Clinic: A=24.2%), autism spectrum disorders (Clinic: A=28.3%, B=25.3%), and attention-deficit-disorder/attention-deficit-hyperactivity-disorder (Clinic: A=26.3%) observed at both clinics in comparison to both control groups (Clinic: A=12.1%, B=13.9%) employed. Children with NDs born post-2001 had a maternal Rh-negativity frequency (13.6%) similar to controls. CONCLUSION: This study associates TCR exposure with some NDs in children.

Intracellular immune dysfunction in myalgic encephalomyelitis/chronic fatigue syndrome: state of the art and therapeutic implications.

http://www.ncbi.nlm.nih.gov/pubmed/18269338?dopt=AbstractPlus

Vrije Universiteit Brussel, Faculty of Physical Education & Physiotherapy, Department of Human Physiology, Building L, Pleinlaan 2, 1050 Brussels, Belgium. Jo.Nijs@vub.ac.be <Jo.Nijs@vub.ac.be>

BACKGROUND: Evidence in support of intracellular immune dysfunctions in people with myalgic encephalomyelitis (ME)/chronic fatigue syndrome (CFS) is accumulating, but few studies have addressed intracellular immunity as a potential therapeutic target. OBJECTIVE: To provide an overview of our present understanding of intracellular immunity in ME/CFS, to relate the intracellular immune dysfunctions to other aspects of the illness like decreased natural killer cell function, the presence of infections and poor exercise performance, and to point to potential therapeutic targets. METHODS: An in-depth review of the scientific literature of intracellular immunity in people with ME/CFS was performed. RESULTS/CONCLUSION: From the scientific literature it is concluded that proteolytic cleavage of the native RNase L enzyme is characteristic of the dysregulation of intracellular immunity in people with ME/CFS, but the origin of the dysregulation is speculative. There is increasing evidence for immune cell apoptosis and upregulation of various aspects of the 2'-5' oligoadenylate (2-5A) synthetase/RNase L pathway in ME/CFS. This review provides the theoretical rationale for conducting studies examining the effectiveness of direct or indirect drug targeting of the 2-5A synthetase/RNase L pathway in ME/CFS patients.

Unravelling intracellular immune dysfunctions in chronic fatigue syndrome: interactions between protein kinase R activity, RNase L cleavage and elastase activity, and their clinical relevance.

http://www.ncbi.nlm.nih.gov/pubmed/18396793?dopt=AbstractPlus

Department of Human Physiology, Faculty of Physical Education and Physiotherapy, Vrije Universiteit Brussel, Belgium.

This study examined possible interactions between immunological abnormalities and symptoms in CFS. Sixteen CFS patients filled in a battery of questionnaires, evaluating daily functioning, and underwent venous blood sampling, in order to analyse immunological abnormalities. Ribonuclease (RNase) L cleavage was associated with RNase L activity (rs=0.570; p=0.021), protein kinase R (PKR) (rs=0.716; p=0.002) and elastase activity (rs=0.500; p=0.049). RNase L activity was related to elastase (rs=0.547; p=0.028) and PKR activity (rs=0.625; p=0.010). RNase L activity (rs=0.535; p=0.033), elastase activity (rs=0.585; p=0.017) and RNase L cleavage (rs=0.521; p=0.038) correlated with daily functioning. This study suggests that in CFS patients an increase in elastase activity and subsequent RNase L cleavage is accompanied by increased activity of both the PKR and RNase L enzymes. RNase L and elastase activity are related to daily functioning, thus evidence supporting the clinical importance of these immune dysfunctions in CFS patients was provided.

Air emissions from Wagerup alumina refinery and community symptoms: an environmental case study.

http://www.ncbi.nlm.nih.gov/pubmed/17848859?dopt=AbstractPlus

Alcoa of Australia, PO Box 252, Applecross WA 6953, Australia. michael.donoghue@alcoa.com.au

Commissioning of a liquor burner at Wagerup alumina refinery gave rise to complaints of malodor and irritation among employees. Subsequently, community members complained about odor and various health issues. Some employees and community members were diagnosed by general practitioners as having multiple chemical sensitivity. After implementation of emission controls, the situation improved; however, community concerns lingered. This paper describes this experience and summarizes several recent investigations including air dispersion modeling, health risk assessment, ambient air quality monitoring, and complaints analyses. It is concluded that refinery emissions currently present negligible risks of acute or chronic health effects including cancer. Communication of these findings has been generally well received, but modifying the perception of risk among some elements of the community has been difficult. Organizations need to effectively address both technical and perception of risk issues.

123 Reed Way in Santa Cruz CA 95060

This listing was just sent to me to be distributed with permission.  It's a home for sale that is listed with a realtor who has MCS herself and is willing to accommodate the needs of a buyer with MCS.  I have no financial interest.  For those interested or seeking housing:
---------
My name is Susi Love and I am a Realtor with MCS in Santa Cruz, CA.

I have a house coming up for sale (not officially on the market yet, but will be in a few days)

It is in a fantastic location for commuting...VERY close to everything (beach, downtown, highway access, hiking/walking trails) but is quiet with a pretty secluded back yard that looks out over the canal. It's a pretty amazing property to be so close to everything that you could walk, but also have quiet and privacy!! It's tucked away down a long driveway.

I am posting here because the owners are about to put it on the market for sale again, at a much lower price than they offered it just months ago. They are about to do a little remodeling to make it nice for the showing and new owners (new carpet, paint, etc.) and I would love to stop them before they do that and bring them a buyer who would prefer low or no-VOC paint and non-toxic flooring.

They are especially cooperative and wonderful sellers, so I know they would put in these things specially for a buyer if we could get to them with an offer before they arrange for the new paint and carpet. I'm just not sure they would want to take the risk of putting out extra money for these things if they thought the potential buyers wouldn't care. They don't know anything about MCS, but are very eager to sell and to please any potential buyers coming in. And since I am their Realtor and I have MCS myself, I know they will value my opinion.

If you would like to see photos of the property and get more details about it go to:

www.mlslistings.com

and type in mls # 734952

The listing will show as C for cancelled, as it was pulled off the market for a while and they hired me. The address is 123 Reed Way in Santa Cruz CA 95060

The home is:
2338 Square Feet
8,232 Sq. Ft lot, backs up to a canal down below
13 years old
3 Bedrooms
2.5 Baths
(Nice separation of space)
Large bathrooms with low flow toilets
Very Light and Spacious throughout
Nice kitchen with tile counters and a gas stove, which could easily be replaced with an electric one
Cathedral Ceilings
Fireplace
Bonus room off of garage
2 Car garage...but you can only fit one car in there with current bonus room
Private and quiet
Centrally located

This home was listed most recently at $849,000 and is now being offered for somewhere between $789 and $759. (owners haven't decided on an exact price yet) The house is a foreclosure hence the much cheaper price. It is currently owned by the private group of investors who financed the mortgage originally. They are sweet people who are easy to work with.

Please call me asap if you might be interested, or if you know someone who might be interested...I could hold off on the new carpet and paint if I thought there was some interest.

Thanks!

California Biomonitoring Survey

From the California Environmental Contaminant Biomonitoring Program

California's new biomonitoring program is intended to track and evaluate toxic environmental chemicals in California residents. Please click on the link below to take the program's Chemical Selection Survey and tell us which chemicals you think the program should measure, and what you think should influence the choice of these chemicals. This survey will take about 20 minutes to complete.

http://tinyurl.com/4qskwz

Please share the link to this survey with others who you think may have an interest in participating in this effort. The survey will also be available in a Spanish language version soon. The deadline for completing the survey is April 30th.

Opinions provided by people responding to this survey will be shared in summary form with the program's Scientific Guidance Panel, which will recommend chemicals to measure. (The Panel is a group of outside experts that, by law, provides advice on the state biomonitoring program.) The summary will also be made available to the public. Panel members and program staff are very interested in receiving public input on these issues.

You can also find the Chemical Selection Survey by visiting the California Biomonitoring Program's website at www.oehha.ca.gov and click on "Biomonitoring".

Living the toxin-free life

Living the toxin-free life
http://www.thesunchronicle.com/articles/2008/04/08/features/2989676.txt

There are plastic baby bottles that leach chemicals, lotions and fragrances with toxins that can enter the bloodstream and disrupt enzymes, and household cleaning products that sanitize but can cause health problems.
 
And as if that isn't enough, there are hundreds of new chemicals introduced to our environment every year, most of which are not government-approved or tested for effects on human health.

With all that in mind, which products should you use? What's a mother (or father) to do? What's most everybody to do?

Evaluation of volatile organic compounds (VOCs) emitted from household products by small chamber test method

Evaluation of volatile organic compounds (VOCs) emitted from household products by small chamber test method
http://www.ncbi.nlm.nih.gov/pubmed/18220050?dopt=AbstractPlus

Tanaka-Kagawa T, Jinno H, Obama T, Miyagawa M, Yoshikawa J, Komatsu K, Tokunaga H.

Kokuritsu Iyakuhin Shokuhin Eisei Kenkyusho Hokoku. 2007;(125):79-85.

Identification and removal/replacement of sources of indoor air pollutants, such as volatile organic compounds (VOCs) and aldehydes, are most effective measures to reduce indoor chemical exposures. For instance, formaldehyde emissions from building materials have been successfully decreased by the restrictions on interior finishing materials under the amended Building Standard Low in Japan. This study was performed to estimate quantitatively influence of household products on indoor air quality. VOC emissions were investigated for 51 products including interior materials, bedclothes, stationeries, toys and printed matters by the small chamber test method (JIS A 1901) under the standard conditions of 28 degrees C, 50% relative humidity and 0.5 times/h ventilation. Total VOC (TVOC) emissions from the tablecloth and gloves, both of which were made of polyvinyl chloride, showed the highest emission rates; over 2000 microg/(m2 x h) after 1 day, and then rapidly decreased to less than 500 microg/(m2 x h) in a week. Among stationeries/toys for schoolchildren and infants, jigsaw puzzle and play mat exhibited higher TVOC emission rates (38 and 24 microg/(m2 x h) after 1 day, respectively). As for VOCs emitted from printed matters, high boiling-point compounds (higher than that of n-tridecane) were typically identified along with toluene, xylenes and ethylbenzene. These results revealed that VOC emissions from household products may influence significantly indoor air quality.

FCognitive and neurobiological alterations in electromagnetic hypersensitive patients: results of a case-control study

Cognitive and neurobiological alterations in electromagnetic hypersensitive patients: results of a case-control study

http://www.ncbi.nlm.nih.gov/pubmed/18366821?dopt=AbstractPlus

Landgrebe M, Frick U, Hauser S, Langguth B, Rosner R, Hajak G, Eichhammer P.

Department of Psychiatry, Psychosomatics, and Psychotherapy, University of Regensburg, Regensburg, Germany.

Psychol Med. 2008 Mar 26;:1-11

BACKGROUND: Hypersensitivity to electromagnetic fields (EMF) is frequently claimed to be linked to a variety of non-specific somatic and neuropsychological complaints. Whereas provocation studies often failed to demonstrate a causal relationship between EMF exposure and symptom formation, recent studies point to a complex interplay of neurophysiological and cognitive alterations contributing to symptom manifestation in electromagnetic hypersensitive patients (EHS). However, these studies have examined only small sample sizes or have focused on selected aspects. Therefore this study examined in the largest sample of EHS EMF-specific cognitive correlates, discrimination ability and neurobiological parameters in order to get further insight into the pathophysiology of electromagnetic hypersensitivity.

Method: In a case-control design 89 EHS and 107 age- and gender-matched controls were included in the study. Health status and EMF-specific cognitions were evaluated using standardized questionnaires. Perception thresholds following single transcranial magnetic stimulation (TMS) pulses to the dorsolateral prefrontal cortex were determined using a standardized blinded measurement protocol. Cortical excitability parameters were measured by TMS.

RESULTS: Discrimination ability was significantly reduced in EHS (only 40% of the EHS but 60% of the controls felt no sensation under sham stimulation during the complete series), whereas the perception thresholds for real magnetic pulses were comparable in both groups (median 21% versus 24% of maximum pulse intensity). Intra-cortical facilitation was decreased in younger and increased in older EHS. In addition, typical EMF-related cognitions (aspects of rumination, symptom intolerance, vulnerability and stabilizing self-esteem) specifically differentiated EHS from their controls.

CONCLUSIONS: These results demonstrate significant cognitive and neurobiological alterations pointing to a higher genuine individual vulnerability of electromagnetic hypersensitive patients.

Green clean: Chemical concern grows, so do 'friendly' products

The household cleaning products aisle of the grocery store presents a dizzying array of choices … and some scary-sounding possibilities, if you read the fine print.

The label for Tilex mold and mildew remover, for example, warns that if a user inhales the fumes and stops breathing, 911 should be called. Sani-Flush toilet bowl cleaner is labeled "corrosive" and advises that the product may cause irreversible damage if it gets in a user's eyes.

Debi Butler doesn't have to worry, though.

She instructs her cleaning service to use nothing but water — plain water — to clean her Bettendorf home.

Comment: I find this interesting as I've always used coffee to offset a bad reaction, particularly a bad respiratory reaction.  It quiets it right down within minutes where nothing else works.  I noticed this on my own and then my doctor who treats my MCS recommended it as well.  He suggested it to help dilate the bronchials when I have bronchi spasms.  Also, it seems to fit with Pall's theory on the NO/ONOO- cycle of biochemistry in relation to the more permeable blood-brain barrier.
 
NFI in the cofffe industry!  :)  And yes, organic is best to avoid chemicals used to process commercial coffee.  I am not suggesting everyone go out and use caffeine!  Especially those with adrenal problems.  Just sharing a point of interest for deeper thought, comment, and investigation.  I'm quite well aware that some react to caffeine and/or coffee and others find it beneficial.
 
"Caffeine is a safe and readily available drug and its ability to stabilise the blood brain barrier means it could have an important part to play in therapies against neurological disorders."

"The "blood brain barrier" is a filter which protects the central nervous system from potentially harmful chemicals carried around in the rest of the bloodstream.

Other studies have shown that high levels of cholesterol in the blood can make this barrier "leaky". "

Daily caffeine 'protects brain'

Coffee may cut the risk of dementia by blocking the damage cholesterol can inflict on the body, research suggests.

Peripheral tinnitus is a good candidate for inclusion under the NO/ONOO cycle etiological mechanism, fitting each of the five principles of this mechanism. Cases of tinnitus are initiated by at least 11 short-term stressors increasing nitric oxide or other cycle mechanisms. Such cycle elements as N-methyl-D-aspartate activity; oxidative stress; nitric oxide; peroxynitrite; vanilloid activity; NF-kappaB activity; and intracellular calcium levels are all reported to be elevated in tinnitus. Tinnitus is comorbid with some putative NO/ONOO- cycle diseases. Most important, multiple agents that down-regulate NO/ONOO- cycle biochemistry are reported to be helpful in the treatment of tinnitus and related diseases. Previous studies suggested that NO/ONOO cycle diseases may be best treated with complex combinations of agents predicted to lower NO/ONOO- cycle biochemistry, and such combinations may be helpful in tinnitus treatment. Other inner-ear-related defects, such as acute or progressive hearing loss, vertigo, and dizziness, may also be NO/ONOO cycle diseases.
