Atopic dermatitis is a chronic, pruriginous, reactional and recidivating dermatosis most frequently presented among infants and young children. Genetic and environmental factors as well as allergen exposure have been identified as risk factors of atopic dermatitis 2. More specifically, the early introduction of supplemental feedings as well as the diversity of the diet feeding 4 or more different food groups appears to increase the risk of atopic dermatitis 3.

However, a definitive role of food hypersensitivity as a causal or promoting factor of atopic dermatitis is not yet definitively established 6,7. We therefore designed the present study in order to investigate the relationship between hypersensitivity to cow's milk, hen egg, wheat, fish, soy, or legumes and atopic dermatitis in young children. Cow's milk, hen egg, wheat, is cereal a good snack before bed and peanuts are among the most common foods with allergenic potential in childhood 8,9.

As secondary study outcomes, positive family history of allergies and timing of weaning were example of causal-comparative research paper as potential contributors of the risk of atopic dermatitis. The study consisted of two phases. The first phase was designed as a case-control study. The second phase was a reevaluation performed 4 years later.

The diagnosis was confirmed according to the criteria established by Hanifin and Rajka The control group consisted of children receiving orthopedic treatment at the HIM, without any neoplasic, pulmonary, or infectious diseases, and not taking any medication chronically. Control children were carefully examined to rule out any clinical evidence of atopic dermatitis.

Information about duration of breastfeeding, the age at which infants were weaned with different foods, family history of asthma, allergic rhinitis, atopic dermatitis and urticaria, were obtained from the mothers. Food hypersensitivity was evaluated by skin prick test and patch test. Skin prick test for cow's milk, hen egg yolk and whitewheat, fish, soy, and legumes was performed as follows. Skin response was evaluated according to Bock and May's criteria 11, The presence of wheal and erythema was evaluated min after the allergen challenge.

Example of case control study pdf indurated wheal of a diameter of at least 3 mm was considered as a positive test of food hypersensitivity. Patch test was performed as previously described elsewhere The occlusion time was 48 hours, and skin reaction was evaluated at 20 min and 24 hours after removal of the cups. Statistical analysis.

Independent proportions of study outcomes were compared between cases and controls by means of the z test. For those proportions that were significantly different P Cases and controls were comparable in their demographic characteristics table 1. There was no difference between example of case control study pdf in the prevalence of either positive skin prick test or positive patch test for food hypersensitivity.

However, when the diagnostic criteria for food hypersensitivity was extended to a positive result with any of the two skin tests either skin prick or patch example of case control study pdfsignificant differences between cases and controls were observed table 1with an OR of 4. The highest prevalence of positive prick test among cases was for hen egg and legumes, followed by cow's milk, fish and soy whereas among controls it was for legumes and fish table 2. The highest prevalence of positive patch tests among both cases and controls was for hen egg.

However, due to the small number of cases having specific food allergies, we did not perform any statistical comparison between cases and controls regarding these differences. No significant difference of family history of allergic diseases asthma, allergic rhinitis, atopic dermatitis and urticaria was observed between cases and controls table 1. In a post-hoc analysis, children who had food hypersensitivity were compared to children without it, independently of the presence or absence of AD.

In the second phase of the study, 4 years later, we were able to reinvestigate the state of AD in 13 Of them, 11 followed an exclusion diet and 6 Of the 29 controls, we obtained information from 15 Of them, only one case developed atopic dermatitis. In comparison to control children, an OR of 4. Our results are in agreement with previous reports showing that a large proportion of children and infants with AD also have food hypersensitivities or food allergies 2,5.

In Mexico, the example of case control study pdf period is typically limited to 45 days postpartum. However, this is not an isolated example. A British study showed that the median age at example of case control study pdf of solid food was 11 weeks Similarly, no relationship between early weaning and atopic dermatitis was recently found in a European study cohort 15and another study suggested that the early introduction of solids might be less harmful than was initially though In contrast, there are current European and American and recommendations to exclusively breastfeed babies for at one variable graph example months 3.

Indeed, our study cannot suggest any modification to these recommendations solely based on our results. However, our findings may help in counseling example of case control study pdf who cannot exclusively breastfeed their babies for different reasons and who should be reassured that there is some evidence that early weaning may not increase the risk of atopy in their infants.

In conclusion, the present study found a higher risk of atopic dermatitis among young children who had hypersensitivity to cow's milk, hen egg, wheat, fish, soy, or legumes. Positive family history of allergies and early weaning were not found to be relevant risk factors. The authors are grateful to Ms. Olivia Tischler for editing the manuscript.
