The association between second-hand smoke exposure and adolescent middle
ear
Quoted message said:problems has not been examined. A random sample stratified by region was
drawn
Quoted message said:from a list that included approximately 40% of all Florida households
with
Quoted message said:children in grades 4-7. A total of 785 Florida adolescents initially
enrolled
Quoted message said:in the 4th-7th grade participated in three telephone interviews
conducted over
Quoted message said:a 24-month period. At the round 3 interview, 10.3% of participants
reported one
Quoted message said:or more earaches within the previous 30 days. Several second-hand smoke
exposure questions asked at each of the three interviews were associated
with
Quoted message said:the number of reported earaches. Stepwise polytomous logistic regression
indicated that parental smoking inside the home reported at the round 3
interview was associated with the number of reported earaches (OR=3.11,
95%
Quoted message said:CI=1.70-5.66). Once this variable was selected, none of the other
second-hand
Quoted message said:smoke exposure variables offered additional predictive value (p>.1).
None of
Quoted message said:the non-second-hand smoke exposure variables, including the
participant's own
Quoted message said:history of tobacco use, had any association with the reporting of
earaches
Quoted message said:(p>.05). Second-hand smoke exposure is associated with self-reported
earaches
Quoted message said:in adolescents. These findings should be replicated in a study in which
clinical measures of middle ear function are performed.
PMID: 14668078
There was another report that said that children that sucked their thumbs
had up to 88% few ear infections than those that used a pacifier. I saw
the study once several years ago and don't know if it is nonsense or not.

Involuntary inhalation of tobacco smoke has been shown to aggravate the
allergic response. Antibodies to fungal antigens such as Aspergillus
fumigatus
Quoted message said:(Af) cause an allergic lung disease in humans. This study was carried
out to
Quoted message said:determine the effect of environmental tobacco smoke (ETS) on a murine
model of
Quoted message said:allergic bronchopulmonary aspergillosis (ABPA). BALB/c mice were exposed
to
Quoted message said:aged and diluted sidestream cigarette smoke to simulate 'second-hand
smoke'.
Quoted message said:The concentration was consistent with that achieved in enclosed public
areas or
Quoted message said:households where multiple people smoke. During exposure, mice were
sensitized
Quoted message said:to Af antigen intranasally. Mice that were sensitized to Af antigen and
exposed
Quoted message said:to ETS developed significantly greater airway hyperreactivity than did
mice
Quoted message said:similarly sensitized to Af but housed in ambient air. The effective
concentration of aerosolized acetylcholine needed to double pulmonary
flow
Quoted message said:resistance was significantly lower in Af + ETS mice compared to the Af +
AIR
Quoted message said:mice. Immunological data that supports this exacerbation of airway
hyperresponsiveness being mediated by an enhanced type 1
hypersensitivity
Quoted message said:response include: eosinophilia in peripheral blood and lung sections.
All Af
Quoted message said:sensitized mice produced elevated levels of IL4, IL5 and IL10 but no
IFN-gamma
Quoted message said:indicating a polarized Th2 response. Thus, ETS can cause exacerbation of
asthma
Quoted message said:in ABPA as demonstrated by functional airway hyperresponsiveness and
elevated
Quoted message said:levels of blood eosinophilia.
