Asthma and dehydration edit
Hi, re my revertion of your edits, to expand on my edit summary: " No WP:RS hits for doctor on PubMed, PMID 17921462 temp effect exercise asthma (not originating cause) & 16505610 local vs systemic dehyd. See 14681718 too"
Information that is likely to be challanged must be provided, in an encyclopaedia, with sources to verify it. Policies are WP:Cite from WP:Reliable sources in order to WP:Verify.
Looking on the PubMed directory of journal paper abstracts, I could find no hits for this doctor and asthma. Looking instead for "asthma dehydration" comes up with a few possible papers:
- Manz F (2007). "Hydration and disease". J Am Coll Nutr. 26 (5 Suppl): 535S–541S. PMID 17921462.
-- addresses the exacerbating effects for exercise, but not in itself verification as underlying cause for asthma (i.e. why do non asthmatics on exercising and drying out of airways not get asthma too). - Anderson SD (2006). "How does exercise cause asthma attacks?". Curr Opin Allergy Clin Immunol. 6 (1): 37–42. doi:10.1097/01.all.0000199797.02423.78. PMID 16505610.
-- addresses localalised dry effects, not systemic dehydration and hence does not confirm proposition that increased fluids drunk will necessarily help. - Kalhoff H (2003). "Mild dehydration: a risk factor of broncho-pulmonary disorders?". Eur J Clin Nutr. 57 Suppl 2: S81–7. doi:10.1038/sj.ejcn.1601906. PMID 14681718.
-- is useful background reading on this, but again did not directly seem to support the details of your edit. - Yun AJ, Lee PY, Bazar KA (2005). "Clinical benefits of hydration and volume expansion in a wide range of illnesses may be attributable to reduction of sympatho-vagal ratio". Med. Hypotheses. 64 (3): 646–50. doi:10.1016/j.mehy.2004.07.014. PMID 15617881.

-- suggests blood volume expandion causes effects on vagal sympathetic tone resulting in a number of effects (ie an indirect effect on asthma) - Kotaru C, Hejal RB, Finigan JH; et al. (2003). "Desiccation and hypertonicity of the airway surface fluid and thermally induced asthma". J. Appl. Physiol. 94 (1): 227–33. doi:10.1152/japplphysiol.00551.2002. PMID 12391050.
{{cite journal}}: Explicit use of et al. in:|author=(help)CS1 maint: multiple names: authors list (link)
-- suggests that drying of the airway is not responsible for exacerbations of asthma - Moloney E, O'Sullivan S, Hogan T, Poulter LW, Burke CM (2002). "Airway dehydration: a therapeutic target in asthma?". Chest. 121 (6): 1806–11. PMID 12065342.
{{cite journal}}: CS1 maint: multiple names: authors list (link)
-- finds that humidification of the inhaled air is useful in asthma atatcks.
There are other older studies than those I list above, but perhaps most directly relevant was:
- Potter PC, Klein M, Weinberg EG (1991). "Hydration in severe acute asthma". Arch. Dis. Child. 66 (2): 216–9. PMID 2001106.
{{cite journal}}: CS1 maint: multiple names: authors list (link)
-- does seem to directly address overall hydration levels and asthma admissions. It can not of course confirm that dehydration was the primary cause (any child who is ill with cold & cough is likely to have reduced fluid intake and along with increase fluid loss via persperation will if admitted a few days later have some degree of dehydration)
Overall therefore, whilst I am glad for your own positive experiences, I did not see a convincing support in the literature for high fluid intake. But please let me know of any other references that do more directly support the concept :-) David Ruben Talk 15:54, 9 January 2008 (UTC)
The article and its talk page have been deleted, but I've posting this on both Helen's talk page and here:
Getting copyright permission requires more than a mere assertion--certain legal channels must be followed, as delineated here. But the main thing to remember that Wikipedia is an encyclopedia, not an advertising medium or a provider of free web space. As a secondary school, VBA is certainly notable enough to merit an article here, but the information therein needs to be verifiable from references in third-party reliable sources. Furthermore, the article needs to maintain a neutral point of view and not be prmotional in nature, so the testimonial is almost certainly inappropriate for inclusion regardless of permission. See also the FAQ for businesses. --Finngall talk 18:38, 8 May 2008 (UTC)
