Conflict of interest: non-existentInvestigation of maternal practices of breastfeeding and their relation with the infection of the upper airways and otitis media ABSTRACTPurpose: to investigate the practices of mothers during breastfeeding and infant's position and their relationship with the infection of the upper airway and otitis media. Methods: this is a descriptive exploratory study. Semi-structured interviews were conducted with 60 mothers, with questions about breastfeeding, the position of the infant during breastfeeding and the occurrence of infection of the upper airways (IUA) and otitis. In the infants, otoscopy and otoacoustic emissions were performed in both ears. Results: out of the 60 infants, 49 were exclusively breastfed and 11 were not. Regarding the position, 20 mothers reported breastfeeding their infants in the seated position and 40 in the lying position. The occurrence of IUA reported by the mothers was in 10 infants and from these, 6 were breastfed lying down and 4 infants sitting. As for the occurrence of otitis media, according to the mothers, 6 infants had at least one episode of otitis. Out of these infants, 2 were breastfed sitting and 4, lying down. The results indicate no significance between the position during breastfeeding and the occurrence of upper airway infection and otitis media. Conclusion: the practices of mothers during breast-feeding and infant's position are not related to infection of the upper airways and otitis media. Keywords: Breast Feeding; Otitis Media; Infection; Speech, Language and Hearing Sciences RESUMO Objetivo: investigar as práticas das mães durante o aleitamento e o posicionamento do bebê e sua relação com a infecção de via aérea superior e a otite média. Métodos: estudo descritivo exploratório. Realizou-se entrevistas semi-estrututadas com 60 mães, sobre aleitamento materno, posição do lactente durante a amamentação e ocorrência de infecção de vias aéreas superiores e otites. Nos bebês, realizou-se otoscopia e emissões otoacústicas, em ambas as orelhas.Resultados: dos 60 lactentes, 49 eram amamentados exclusivamente e 11 não exclusivo. Com relação à posição, 20 mães relataram amamentar seus filhos na posição sentada e 40 na posição deitada. A ocorrência de IVAS relatada pelas mães foi de 10 bebês sendo que destes, 6 mamavam deitados e 4 bebês sentados. Quanto à ocorrência de otite média, segundo as mães, 6 bebês apresentaram pelo menos um episódio de otite. Destes bebês, 2 eram amamentados sentados e 4 deitados. Os resultados indicam que não há significância entre a posição durante a amamentação e a ocorrência de infecção de via aérea superior e otite média. Conclusão: as práticas das mães durante o aleitamento e o posicionamento do bebê não possuem relação com a infecção de via aérea superior e a otite média.

“…Although this methodology has been used in similar studies 22,30 , it is suggested that in future studies the occurrence of both IVAS and otitis should be investigated objectively or clinically.…”

“…In the early years of life up to two years, normal ear tympanicossicular system acts differently as mass is the dominating physical feature of the ear. After this age, reaching the adult stage, there is a change in behavior which is controlled by stiffness and is better evaluated using probe frequency of 226 Hz [1]. Thus carrying out conventional tympanometry using 226Hz probe tone at early years of life may not serve of much help.…”

Objective: Impairment to hearing during childhood may lead to delay in the speech and language skills, making the communication process more difficult. Early identification and rehabilitation can benefit the children. It is necessary to test the hearing using accurate test procedures. Thus, aim of the study was to compare the use of probe tones (226Hz and 1000Hz probe tone) in tympanometry while testing the neonates for hearing before getting discharged from hospital setup.Method: An inclusion -exclusion criteria was applied in selection of 60 neonates (1-17days). Hearing screening with comparison of 226Hz and 1000Hz probe tone in tympanometry was carried out using a comparative study design. Pressure ranging from + 200 to -400 daPa and a pressure change rate of 600/200 daPa per second was used for testing. Intensity of probe tone was adjusted at 85 dB SPL. Comparison was made for type of tympanogram, ear canal volume, compensated static peak acoustic admittance and tympanometric peak pressure. Sampled paired t test was used to carry out statistical analysis.Results: 1000Hz probe tone surpassed the 226Hz probe tone in testing the neonates using tympanometry. A statistically significant difference was observed in all the sub-sections except similar values for ear canal volume. Conclusion:Many changes occur in the ears of neonates like changes in bone density, mesenchymal loss which has an impact on the mechanical properties of the auditory canal and middle ear system. Thus, 1000Hz probe tone in tympanometry serves a promising tool.

Summary Introduction: The use of conventional tympanometry is not sufficiently sensitive to detect all cases of middle ear changes, and this hinders accurate diagnosis. Objective: To characterize acoustic immittance measures of infants from 0 to 3 months of age using multifrequency tympanometry in a prospective study. Method: 54 infants from 0 to 3 months of age were evaluated. The inclusion criteria included absence of respiratory infections during the evaluation, presence of transient evoked otoacoustic emissions, and absence of risk indicators for hearing loss. The subjects were evaluated by an audiologic interview, a visual inspection of the ear canal, and measures of acoustic immittance at the frequencies of 226 Hz, 678 Hz, and 1,000 Hz. Tympanometric records of the occlusion effect, tympanometric curve type, tympanometric peak pressure, equivalent ear canal volume, and peak compensated static acoustic admittance were collected. Results: The results indicated the presence of an occlusion effect (2.88% at 226 Hz, 4.81% at 678 Hz and 3.85% at 1,000 Hz), predominance of a tympanometric curve with a single peak (65.35% at 226 Hz, 81.82% at 678 Hz, and 77.00% at 1,000 Hz), and tympanometric peak pressure ranging from -155 to 180 daPa. Further, the equivalent ear canal volume increased with the frequency of the probe (0.64 mL at 226 Hz, 1.63 mho at 678 Hz, and 2.59 mmho at 1,000 Hz) and the peak compensated static acoustic admittance values increased with an increase in frequency (0.51 mL at 226 Hz, 0.55 mmho at 678 Hz and 1.20 mmho at 1,000 Hz). 93.06% of the tympanograms were classified as normal at 226 Hz, 81.82% at 678 Hz, and 77.00 % at 1,000 Hz, respectively. Conclusion: Taken together, these results demonstrated that utilizing these evaluations made it possible to characterize the acoustic immittance measures of infants.
