The goal of this work is to develop an innovative method that combines bioprinting and endoscopic imaging to repair tympanic membrane perforations (TMPs). TMPs are a serious health issue because they can lead to both conductive hearing loss and repeated otitis media. TMPs occur in 3 to 5% of cases after ear tube placement as well as in cases of acute otitis media (the second most common infection in pediatrics), chronic otitis media with or without cholesteatoma, or as a result of barotrauma to the ear. About 55,000 tympanoplasties, the surgery performed to reconstruct TMPs, are performed every year and the commonly used cartilage grafting technique has a success rate between 43% to 100%...

Acute otitis media is a common diagnosis encountered by emergency medicine providers. With appropriate antibiotic treatment, patients with otitis media, in general, have minimal long-term sequela from their underlying infection (Limb et al., 2017 [1]). However, untreated cases can develop life-threatening complications that require prompt intervention. We report a case of an 8-year-old that developed Gradenigo's syndrome, a condition characterized by the triad of otitis media, facial pain in the distribution of the trigeminal nerve, and abducens nerve palsy (Yeung and Lustig, 2016; Janjua et al...

Objective: There is a growing body of data that demonstrates increased infectious disease outcomes for HIV-exposed uninfected (HIV-EU) infants as compared to their HIV-unexposed (HU) counterparts. We hypothesized that these HIV-EU infants are at greater risk for infectious morbidity and mortality when compared to the general childhood population. We therefore aimed to characterize infections and growth outcomes among HIV-EU infants in Jamaica during their first two years of life. By identifying these outcomes, specific interventions could be implemented to mitigate this risk of morbidity and mortality...

INTRODUCTION: Antibiotics represent one of the most widely prescribed therapeutic agents in children. It has been estimated that 30-50% of antibiotic prescriptions for this population are inappropriate. In this scenario, analysis of prescription data provides an invaluable source of information as a basis for implementing strategies for improvement in this field. OBJECTIVE: To assess the appropriateness of antibiotic prescriptions in a paediatric population at an emergency department...

BACKGROUND: Interferences between pathogenic bacteria and specific commensals are known. We determined the interactions between nasopharyngeal microbial pathogens and commensals during viral upper respiratory tract infection (URI) and acute otitis media (AOM) in infants. METHODS: We analyzed 971 specimens collected monthly and during URI and AOM episodes from 139 infants. The 16S rRNA V4 gene regions were sequenced on the Illumina MiSeq platform. RESULTS: Among the high abundant genus-level nasopharyngeal microbiota were Moraxella, Haemophilus, and Streptococcus (3 otopathogen genera), Corynebacterium, Dolosigranulum, Staphylococcus, Acinetobacter, Pseudomonas, and Bifidobacterium...

Pneumococcal diseases are associated with a significant clinical and economic burden. The 7-valent pneumococcal conjugate vaccine (PCV-7) has been used for the immunization of newborns against invasive pneumococcal diseases (IPD) in Italy while now the pneumococcal non-typeable Haemophilus influenzae protein D conjugate vaccine (PHiD-CV) and the 13-valent pneumococcal conjugate vaccine (PCV-13) are available. The aim of this analysis was to compare the estimated health benefits, cost and cost-effectiveness of immunization strategies vs...

Recurrence of acute otitis media (RAOM) is a relevant issue in the clinical practice. "Bacteriotherapy" has been proposed as an option in children with RAOM. Streptococcus salivarius 24SMB nasal spray has been previously demonstrated to reduce the risk of acute otitis media (AOM) in otitis-prone children. The current retrospective and observational study aimed to confirm this outcome in a real-life setting, such as the common pediatric practice. Group A (108 children) served as control; group B (159 children) was treated with S...

Otitis media (OM) is a major cause of morbidity in pediatric and adult patients. This inflammatory condition is characterized by mucous cell hyperplasia that is thought to produce mucins from the middle ear mucosa. We are interested in the role of Notch signalling pathway in this inflammatory process. Using an acute otitis media (AOM) mouse model through injection of Streptococcus Pneumoniae into the middle ear, histopathologic examination and quantitative RT-PCR, acute inflammation with the thickness of mucosa, Goblet cell hyperplasia, and cilia loss were determined and gene expression related to the Notch signaling pathway were evaluated...

OBJECTIVE: To assess whether antimicrobial therapy in young children with acute otitis media reduces time to resolution of symptoms, overall symptom burden, and persistence of otoscopic evidence of infection. We used a cost-utility model to evaluate whether immediate antimicrobial treatment seems to be worthwhile, and if so, which antimicrobial agent is most cost effective. STUDY DESIGN: We compared the cost per quality-adjusted life-day of 5 treatment regimens in children younger than 2 years of age with acute otitis media: immediate amoxicillin/clavulanate, immediate amoxicillin, immediate cefdinir, watchful waiting, and delayed prescription (DP) for antibiotic...

BACKGROUND: Pneumococcal conjugate vaccine (PCV) was introduced in 2000. The first 7-valent vaccine was followed by a 13-valent vaccine (PCV13) with the same conjugate, and a 10-valent vaccine (PCV10), conjugated to protein D from H. influenzae. The vaccines offer some protection against pneumococcal acute otitis media (AOM), and, with PCV10, possibly also some protection against H. influenzae AOM. PCV7 was introduced in Sweden in 2009, but from 2010, Swedish counties were free to use either PCV13 or PCV10...

PURPOSE: Streptococcus pneumoniae is a commensal bacterium that normally colonizes the human nasopharyngeal cavity. Once disseminated, it can cause several diseases, ranging from non-invasive infections such as acute otitis media and sinusitis through to invasive infections with higher mortality, including meningitis and septicaemia. Since the identification of the first S. pneumoniae strain with decreased susceptibility to penicillin in the 1960s, antibiotic resistance among S. pneumoniae has increased disturbingly and the mechanisms of resistance have begun to unfold...

Acute otitis media (AOM) is one of the most common pediatric conditions worldwide. Peak age of occurrence for AOM has been identified within the first postnatal year and it remains frequent until approximately six postnatal years. Morphological differences between adults and infants in the cartilaginous Eustachian tube (CET) and associated structures may be responsible for development of this disease yet few have investigated normal growth trajectories. We tested hypotheses on coincidence of skeletal growth changes and known ages of peak AOM occurrence...

REVIEW
Anna Granath
PURPOSE OF REVIEW: To survey current strategies for treatment and prevention of recurrent acute otitis media (rAOM). RECENT FINDINGS: Treatment with systemic antibiotics is required in recurrent episodes of acute otitis media. A cautious attitude is recommended due to antibiotic resistance. Antibiotics also provide effective prophylaxis for rAOM. Topical treatment with ear drops is recommended in rAOM with otorrhea from tympanostomy tubes. Pneumococcal conjugated vaccines seem to have a moderate reductive effect on overall otitis media...

Metastatic renal cell carcinoma (RCC) involving the temporal bone is a rare entity. It is usually asymptomatic and misdiagnosis as acute otitis media, mastoiditis, and Ramsay-Hunt syndrome in early onset is not uncommon. We report a case of RCC metastasis to the postoperative temporal bone in the middle of molecular targeted therapy. A 60-year-old man presented left facial palsy with severe retro-auricular pain and he also underwent left middle ear surgery for cholesteatoma more than 30 years before and had been aware of discontinuous otorrhea; therefore, initially we speculated that facial palsy was derived from recurrent cholesteatoma or Ramsay-Hunt syndrome...

INTRODUCTION: Petrositis is a rare but severe complication of acute otitis media and mastoiditis. Despite efficient antibiotic therapy, there are still reports of both intratemporal and intracranial complications of otitis media with the potential risk of high morbidity and mortality. Petrositis has traditionally been treated with surgery, but recent advances in imaging, with improved antibiotic treatment, allow more conservative management. CASE REPORT: In this case report we describe the clinical course and treatment of a 33-year-old man with petrous apicitis who presented with severe otalgia, retro-orbital pain, and sixth cranial nerve palsy Gradenigo syndrome...
