Objective: Acute otitis media (AOM) causes an inflammatory response in the middle ear. We assessed differences in innate immune responses involved in bacterial defense at onset of AOM in children who were stringently defined as otitis prone (sOP) and children not otitis prone (NOP).
Study Design: Innate immune genes analysis from middle ear fluid (MEF) samples of children.
Methods: Genes of toll-like receptors (TLR), nod-like and retinoic acid-inducible gene-I-like receptors, downstream effectors important for inflammation and apoptosis, including cytokines and chemokines, were studied from MEF samples by using a real-time polymerase chain reaction array. Protein levels of differentially regulated genes were measured by Luminex.
Results: Gene expression in MEF among children who were sOP was significantly different in upregulation of interleukin 8, secretory leukocyte peptidase inhibitor, and chemokine (C-C motif) ligand 3, and in downregulation of interferon regulatory factor 7 and its related signaling molecules interferon alpha, Toll-like receptor adaptor molecule 2, chemokine (C-C motif) ligand 5, and mitogen-activated protein kinase 8 compared with children who were NOP. Differences in innate gene regulation were similar when AOM was caused by Streptococcus pneumoniae or nontypeable Haemophilus influenzae.
Conclusion: Innate-immune response genes are differentially regulated in children who were sOP compared with children with NOP.

Background And Objectives: Serous otitis media (SOM), also called otitis media with effusion (OME) or glue ear, is a collection of non-purulent fluid within the middle ear space. Children with cleft palate are more prone to develop this condition. This is caused by impaired eustachian tube function in cleft palate.

Background: This systematic review aimed to synthesize the existing evidence on the use of () probiotics as prophylactic or therapeutic tools for pediatric oral, dental, and respiratory diseases.
Methods: A comprehensive search was carried out across multiple databases using the following terms: , probiotic, children, pediatric.
Results: The systematic literature search identified 613 publications, which were meticulously screened, and, ultimately, 15 suitable citations were included in this systematic review.

Background/objectives: The respiratory system is prone to infectious diseases, especially in children below five years of age. Upper respiratory tract infections in children are often associated with Eustachian tube dysfunction and complicated by otitis media with effusion (OME), an inflammatory process within the middle ear, which can lead to hearing loss. Treatment for these infections involves a combination of medication and symptom relief, depending on the severity and cause of the infection.
