Background: Reductions in otitis media (OM) burden following rollout of pneumococcal conjugate vaccines (PCVs) have exceeded predictions of vaccine impact. In settings with active surveillance, reductions in OM caused by vaccine-targeted pneumococcal serotypes have co-occurred with reductions in OM caused by other pathogens carried in the upper-respiratory tract of children. To understand these changes, we investigated the progression of vaccine-targeted and non-vaccine pneumococcal serotypes from carriage to OM before and after vaccine rollout...

INTRODUCTION: Necrotizing otitis externa remains a severe and sometimes life-threatening disease in diabetic patient. Many therapeutic approaches have been described but what about the real benefit of hyperbaric oxygenotherapy in the management of this disease? METHODS: The authors reported a retrospective study about 42 patients treated for necrotizing external otitis over a period of 9 years (2006 to 2014). The patients were treated either by only antibiotherapy (23 cases) or with both antibiotherapy and hyperbaric oxygenotherapy (19 cases)...

A 4-year-old cocker spaniel, male, of 12kg body weight was presented because of the onset of polyuria or polydipsia. From the first months of its life, the dog had exhibited constant serous to mucopurulent nasal discharge, productive cough, sneezing, reverse sneezing, otitis, and recurrent episodes of fever. The respiratory signs had been treated several times with antibiotics, without ever achieving a complete resolution. Clinical examination revealed normal rectal temperature (38.3°C), increased respiratory rate (40breaths/min), a copious mucous nasal discharge and right deviation of the heart apex beat (ictus cordis)...

BACKGROUND: Concerns about non-typeable Haemophilus influenzae (NTHi) in otitis media (OM) have grown after the introduction of pneumococcal conjugate vaccine (PCV). We aim to better understand the clinical role of NTHi in pediatric OM. METHODS: Middle ear fluid samples from children <18 years with OM were obtained from 2010 to 2015. For culture-positive episodes (Streptococcus pneumoniae, H. influenzae, Moraxella catarrhalis, and Streptococcus pyogenes), patients' demographic and clinical information were reviewed and analyzed...

OBJECTIVES: Calgranulins (calcium-binding proteins S100A8, S100A9 and S100A12) are predominant cytoplasmic proteins of neutrophils and produced by various cells, playing multiple functions in innate immunity and the inflammatory process. Although up-regulated expression of S100A8 and S100A9 genes were observed in an animal model of otitis media (OM), their expressions have not been studied in human middle ear epithelial cells in response to the OM pathogen or in patients with recurrent or chronic OM (recurrent OM/RecOM or chronic OM with effusion/COME)...

<i>Staphylococcus caprae</i> was originally isolated from goat milk. This uncommon coagulase-negative staphylococcus, usually associated with animals, has only infrequently been detected in human clinical specimens. Its association with acute otitis media has not been demonstrated so far. The study reports the first isolation of <i>S. caprae</i> from the middle ear fluid of a 12-month-old infant with recurrent, bilateral acute otitis media. Biochemical traits and susceptibility pattern of the isolated strain are also presented...

OBJECTIVE: To survey long-term hearing outcomes and middle ear pathology in a 30-year follow-up in individuals with onset of recurrent acute otitis media (rAOM) before three years of age. METHODS: 28 adults, aged 30.1-31.8 years, who originally - at the age of 12-32 months - participated in a study on rAOM between 1979 and 1983, were re-examined regarding self-reported ear problems, current tympanic membrane changes and audiology. Thirteen subjects had suffered from rAOM during early childhood and 15 subjects served as a control group...

Acute otitis media (AOM) is a common childhood illness. The aim of this study was to assess whether AOM in the first month of life predicts recurrent AOM (rAOM) in early childhood. The medical records of all neonates with AOM and isolation of bacterial pathogen from middle-ear fluid during 2005-2010 were reviewed. Neonates without AOM admitted during the same period for neonatal fever workup were included as controls. Information regarding rAOM and possible risk factors were collected through a phone interview with the parents...

The complement system is an important effector arm of innate immunity and plays a crucial role in the defense against common pathogens. But effective defense and maintenance of homeostasis requires a careful balance between complement activation and regulation. Factor I (FI) is one of the most important regulators of the complement system. Complete FI deficiency is a rare autosomal recessive disorder typically resulting in severe, recurrent infection by encapsulated bacteria. In the present study, we describe two patients from unrelated families with complete FI deficiency diagnosed at very different ages: Patient 1 is a 60-year-old man who had experienced several severe infections (pneumonia, meningitis, sepsis) since childhood, one of which caused significant and permanent neurologic sequelae...

INTRODUCTION: Patients with Turner syndrome (TS) have craniofacial malformations, such as Eustachian tube hypoplasia and dysfunction and velar dysfunction, which foster acute otitis media. The aim of this study was to inventory pediatric otologic disorders in patients with TS at their first ENT consultation in our center. PATIENTS AND METHODS: We reviewed the ENT consultation data of pediatric TS patients followed in our center between 2005 and 2015: otoscopy, hearing threshold, and history of acute otitis media or ENT surgery...

In this paper, we describe, for the first time, the genetic organization of the blpU-like cassette in Streptococcus salivarius24SMBc by entire genome sequencing. This strain has recently been found useful and widely applied as an oral probiotic in the prevention of recurrent otitis media. The 24SMBc blpU-like cassette  is 8,023 bp in length, organized in 11 orfs,of which orf8 encodes for the pore-forming peptide bacteriocin, belonging to class IIc, with a double-glycine leader peptide. The first characterization of blplocus was described inStreptococcus pneumoniae, showing a crucial role in interspecies competition within the nasopharynx...

Acute otitis media (AOM), common childhood infection that is one of leading cause of antibiotic prescriptions for children, is diagnosed at least once in approximately 80% of preschool children and 30-40% of them have recurrent episodes. Antibiotic treatment of AOM is usually empiric, without isolation of otopathogens from middle ear fluid and their antibiotic susceptibility testing. Due to the improper antibiotic use, the infection can persist in some cases, termed AOM treatment failure. This article is protected by copyright...

Inflammatory myofibroblastic tumor (IMT) is a rare tumor in the central nervous system (CNS), mostly being extracranial. Approximately 100 sporadic cases have been reported in the literature. The rarity of the tumor, its various histopathological characteristics, and its variable aggressive course render it difficult to diagnose and treat. IMT is generally a histological diagnosis which is rarely suspected preoperatively. It mimics other intracranial tumors such as giant cell tumor, hemangiopericytoma, anaplastic meningioma, plasmacytoma, and lymphoma...

Infections due to Vibrio cholerae are rarely documented in Israel. Here we report a case of recurrent otitis media in a young male, caused by V. cholerae non-O1/O139. This extra-intestinal infection was caused by V. cholerae O100 and has been associated with freshwater exposure and travel. Symptoms of chronic periodic earaches along with purulent exudate began about one week after the patient suffered a water skiing accident on a river in Australia. The condition lasted for three years, until his ear exudate was examined in a clinical laboratory, diagnosed and treated...

Mastoidectomy, the removal of infected mastoid bones, is a common surgical procedure for the treatment of chronic otitis media. Persistent and recurrent otorrhea and accumulation of keratin debris following open cavity mastoidectomy are still bothersome issues for both patients and otologists. In this study, we used human ear adipose-derived stromal cells (hEASCs) in combination with polycaprolactone (PCL) scaffolds and osteogenic differentiation medium (ODM) to regenerate temporal bone defects. The hEASCs showed stem cell phenotypes, and these characteristics were maintained up to passage 5...

Small supernumerary marker chromosomes (sSMC) are still a major problem in clinical cytogenetics as they cannot be identified or characterized unambiguously by conventional cytogenetics alone. On the other hand, and perhaps more importantly in prenatal settings, there is a challenging situation for counseling how to predict the risk for an abnormal phenotype, especially in cases with a de novo sSMC. Here we report on the prenatal diagnosis of a mosaic tetrasomy 18p due to presence of an sSMC in a fetus without abnormal sonographic signs...

INTRODUCTION: Otitis media is one of the most prevalent childhood diseases. The impact of otitis media on quality of life of Portuguese children is unknown, because of the unavailability of a tool validated in European Portuguese to assess this consequence of otitis media. The Otitis Media-6 questionnaire (Otitis Media-6) is the most frequently used tool to assess health-related quality of life in children with otitis media. This study aims to create a version in the Portuguese language and culturally adapted to Portugal of the otitis media-6 questionnaire...
