Frecuencia de infecciones respiratorias agudas en niños y adolescentes con asma de la provincia de Pinar del Río / Frequency of acute breathing infections in children and adolescents with asthma from Pinar del Río province

Se realizó un estudio epidemiológico analítico, de casos y controles en fase exploratoria, con vistas a determinar si la frecuencia de infecciones respiratorias en niños y adolescentes con asma de la provincia de Pinar del Río superaba la observada en aquellos que no presentaban esa enfermedad, desde julio del 2014 hasta junio del 2015. Para ello se conformaron 2 grupos de 585 integrantes cada uno, o sea un control por cada caso. Luego de procesada la información, se obtuvo un predominio del sexo masculino, en tanto, el catarro común fue la infección que afectó con mayor frecuencia fundamentalmente a los pacientes de 5-9 años de edad. Asimismo, se destacó un incremento del riesgo de padecer -- por orden de frecuencia -- afecciones, tales como catarro común, amigdalitis aguda y neumonía, bronconeumonía, así como neumonía intersticial

An analytic epidemiologic, of cases and controls study in exploratory phase, aimed at determining if the frequency of breathing infections in children and adolescents with asthma from Pinar del Río exceeded the one observed in those that didn't present that disease, was carried out from July, 2014 to June, 2015. Two groups of 585 members each one were conformed for that purpose, that is to say a control for each case. After having processed the information, there was a prevalence of the male sex, while, the common cold was the infection that affected with higher frequency fundamentally those patients aged 5-9. Also, it was emphasized an increment of the risk from suffering -- in order of frequency -- disorders, such as common cold, acute tonsillitis and pneumonia, bronchopneumonia, as well as interstitial pneumonia

The significance of atopic disease family history in the diagnosis of asthma in children / 国际儿科学杂志

There is no specific diagnostic tools or marker for detection of asthma in children.However,A large number of studies have shown that atopic disease and positive family history are the important risk factors.It is helpful for the asthma early diagnosis,proper management and prevention through the analysis of the relationship between childhood asthma and atopic disease as well as positive family history.

Effects of Breastfeeding on the Development of Allergies / 한양의대학술지

Breastfeeding has many positive nutritional and other benefits that influence the maturation of the gastrointestinal mucosa and microflora of the newborn infants. Furthermore, there is evidence that exclusive breastfeeding in the first 4 months protects against atopic dermatitis and early wheezing in infancy, and immunomodulatory reactions of human milk contributes to the reduction of allergic diseases. Some conflicting reports suggest that breastfeeding provides risk for asthma development if there is a positive family history of allergy. Nevertheless breastfeeding is thought to be associated with a lower asthma risk in young children. Consequently exclusive breastfeeding is highly recommended for all infants at both high and low risk of atopy and irrespective of atopic maternal history for at least 4 to 6 months. For the prevention of allergies, however, exclusion of highly allergenic foods such as peanut and eggs from the maternal diet in the sensitized atopic mother during lactation and supply of extensively hydrolyzed food for the high risk infants is necessary.

Relationship between Atopic Dermatitis, Wheezing during Infancy and Asthma Development

There has been a dramatic increase in the prevalence of atopic dermatitis and asthma over the last few decades worldwide, including Korea. They are not only major public health problems with an enormous burden on health care resources but also the diseases adversely affect the quality of life of patients and their family. There are clear epidemiologic parallels in atopic dermatitis, wheezing, and asthma. Atopic dermatitis frequently is the first manifestation of atopic diathesis, which occurs in genetically predisposed individuals. Up to 80% of children with atopic dermatitis will eventually develop asthma and allergic rhinitis later in childhood. Also frequent wheezing in childhood will persist and can progress to asthma later. Therefore principal measures for primary prevention and early intervention for an infant with high risk should start as early as possible during early infancy.

Allergens Causing Atopic Diseases in Canine

Canine atopic skin disease is seasonal or sometimes non-seasonal immune-mediated skin disease which occurs commonly in Korea. The definite clinical sign is systemic pruritus, especially on periocular parts, external ear, interdigit spaces and lateral flank. For diagnosis of this dermatitis, complete history taking followed by intradermal skin test and serum in vitro IgE test needs to be performed. Allergen selection for the diagnosis and treatment of atopic dermatitis should be varied geographically. In this study, with intradermal skin test(IDST) the prevalence of atopic disease and what allergens are involved in are researched. Allergens used for IDST included 26 allergen extracts from six allergen groups: grasses, trees, weeds, molds, epidermal allergens and environmental allergens. The number of allergens was 42 in which the positive and negative controls are included. The most common positive allergen reaction was the house dust mites on IDST(22/35, 63%). The other positive allergen reactions were to flea(3/35, 9%), molds(1/35, 3%), house dusts(2/35, 6%), feathers (1/35, 3%), cedar/juniper(1/35, 3%), timothy grass(1/35, 3%) and dandelion(1/35, 3%). In this study, the most prevalent allergen causing atopic dermatitis in dogs in Korea was the house dust mites followed by the flea.
