Bronchial asthma (BA) is one of the common childhood diseases that affects the respiratory system characterized by recurrent cough, wheezing, chest tightness and difficulty with breathing. The two conditions are different manifestations of allergic disease of the airway;the composition of the inflammatory substrate in the mucosa of allergic patients is similar to the late-phase allergic response seen elsewhere in the respiratory tract, such as in bronchial asthma. Aim: The aim was to compare the impacts of allergic rhinitis and bronchial asthma on tympanometric parameters in children. Patients & Methods: This is a hospital based comparative cross-sectional study. Two groups of participants aged 4 - 12 years, one group with documented clinical diagnosis of allergic rhinitis and the other group with documented clinical diagnosis of bronchial asthma were consecutively selected from ear, nose and throat (ENT) and pediatrics cardiopulmonary outpatient clinics of Aminu Kano Teaching Hospital Kano respectively. Equal number of children aged 4 - 12 years with no history of ENT diseases or bronchial asthma that were selected from elementary schools within the same community served as a control group. An interviewer-administered questionnaire was filled out for all the participants, complete ENT and chest examinations were carried out and subsequently all the selected participants had tympanometry done, findings were recorded and analyzed. Results: The mean age of participants with bronchial asthma was found to be 7.5 ± 2.6 years while participants with allergic rhinitis had the mean age of 6.8 ± 2.1 years. The mean middle ear pressure (MEP) of participants with bronchial asthma was found to be -15.22 dapa and -40.32 dapa in those with allergic rhinitis. Acoustic reflex was found to be absent in 15.4% of the participants with bronchial asthma and 29.6% of allergic rhinitis participants. Type B tympanogram was found in 2.8% of bronchial asthma participants and 7.3% in participants with allergic rhinitis. Type C tympanogram was found in 4.6% of participants with bronchial asthma and 15.5% of participants with allergic rhinitis. Type A tympanogram was found in 90% of participants with bronchial asthma and 75% of participants with allergic rhinitis. The difference between type A, B and C tympanograms of participants with bronchial asthma and those with allergic rhinitis was found to be statistically significant (Type A χ<sup>2</sup> = 14.62, df = 4, p value = 0.01, Type B χ<sup>2</sup> = 14.06, df = 4, p value = 0.01, Type C χ<sup>2</sup> = 17.01, df = 6, p value = 0.01). Conclusion: Participants with allergic rhinitis were found to have more abnormalities of tympanometric parameters compared to participants with bronchial asthma which signifies allergic rhinitis conferred an increased risk of having middle ear diseases and otitis media with effusion compared to bronchial asthma.展开更多

With this regard, pediatricians play a key role in the management of these conditions. The closeness with the family, the knowledge of the clinical case and the care continuity allow the pediatrician to acquire a position of director of every case. When pathological events have a chronic feature, suddenly the quality of life of the whole family changes. For this reason the first communication of chronic disease is very important and the task of the pediatrician should be to provide a positive message to help the family in facing the difficulty of this new challenge. The bronchial asthma is the most common chronic disease worldwide. The incidence, the prevalence, and the mortality of the disease have increased in children over the past decades. These trends are particularly marked above all in preschool children. The success reached by Pediatricians is closely related to the compliance and the implementation of the therapy followed by the little patient and his family. With this regard authors, in this review, focus on the illustration of several strategies, based on the pediatrician’ skills and medicine documents, that can be used for the improvement of communication among pedia- trician-family and child, never forgetting the hu- man aspect of the same doctor, that should con- ciliate with the scientific knowledge in the taking care of a specific chronic disease.展开更多

BHR has been proposed as a prognostic marker of asthma severity and persistence, and may also be used to control pharmacological management of asthma. The most recent data on the prevalence and development of BHR in childhood and its predictive value for subsequent asthma development in late adolescence and adulthood is discussed in this review. According to the BHR-related scientific articles written in the English language and indexed in the publicly searchable PubM ed database, the prevalence of BHR varies based upon the methods used to assess it and the population examined. In general, however, BHR prevalence is reduced as children grow older, in both healthy and asthmatic populations. While asthma can be predicted by BHR, the predictive value is limited. Reduced lung function, allergic sensitization, female sex, and early respiratory illness have been identified as risk factors for BHR. The collective studies further indicate that BHR is a dynamic feature related to asthma, but asymptomatic BHR is also common. Ultimately, the prevalence of BHR varies depending on the population, the environment, and the evaluation methods used. While both the methacholine challenge and the exercise test may predict asthma in adolescence or early adulthood, the predictive value is higher for the methacholine challenge compared to the exercise test. The collective data presented in the present study demonstrate how BHR develops through childhood and its relation to bronchial asthma.展开更多
