Biofilms formed by nontypeable Haemophilus influenzae (NTHI) are central to the chronicity, recurrence, and resistance to treatment of multiple human respiratory tract diseases including otitis media, chronic rhinosinusitis, and exacerbations of both cystic fibrosis and chronic obstructive pulmonary disease. Extracellular DNA (eDNA) and associated DNABII proteins are essential to the overall architecture and structural integrity of biofilms formed by NTHI and all other bacterial pathogens tested to date. Although cell lysis and outer-membrane vesicle extrusion are possible means by which these canonically intracellular components might be released into the extracellular environment for incorporation into the biofilm matrix, we hypothesized that NTHI additionally used a mechanism of active DNA release...

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...

Bing Pang, W Edward Swords
Haemophilus parainfluenzae is a nutritionally fastidious, Gram-negative bacterium with an oropharyngeal/nasopharyngeal carriage niche that is associated with a range of opportunistic infections, which include infectious endocarditis and otitis media (OM). These infections are often chronic/recurrent in nature and typically involve bacterial persistence within biofilm communities that are highly resistant to host clearance. This study addresses the primary hypothesis that H. parainfluenzae forms biofilm communities that are important determinants of persistence in vivo The results from in vitro biofilm studies confirmed that H...

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...

Heterozygous gain-of-function (GOF) mutations in the signal transducer and activator of transcription 1 (STAT1) have increasingly been identified as a genetic cause of autosomal-dominant (AD) chronic mucocutaneous candidiasis (CMC). In this article, we describe a 33-year-old man who experienced chronic refractory candidiasis, recurrent otitis media, and pneumonia resulting in bronchiectasis, severe oral and esophageal candidiases with strictures associated with hypothyroidism and immune hemolytic anemia. His son also suffered from persistent candidiasis, chronic diarrhea, poor weight gain, and pneumonia that resulted in his demise because of sepsis...

The meatoplasty of the external auditory canal is a frequently performed otologic procedure in recurrent otitis externa, eczema or frequent accumulation of cerumen due to a narrow meatus of the external ear canal. Numerous surgical techniques have been described. The M-meatoplasty described by Mirck for addressing the external meatus is widely used. However, this technique does not sufficiently enlarge the external ear canal in all cases. Specifically in patients where the ear canal narrowing is most prominent in the postero- and/or anterosuperior quadrants of the lateral meatus the technique needs some modifications...

Otitis caused by Malassezia pachydermatis is generally a common and recurrent disease in canine clinical pathology. The increased incidence of fungal resistant to antifungal in both humans and pets is a cause for concern and is associated with the indiscriminate use of antifungals. Finding the most effective disinfectants and antifungals has become essential. To evaluate the in vitro inhibitory activity of hydrogen peroxide on the growth of M. pachydermatis and compare its efficacy with commercial ear cleaners...

High-mobility group box 1 (HMGB1) is a nuclear non-histone protein, playing a critical role as a mediator between innate and acquired immunity; when released extracellularly, it coordinates the cellular stress response (under necrosis, bacterial lipopolysaccharide stimulation) and acts as an inflammatory marker and cytokine. The aim of the study was to demonstrate whether HMGB1 is over-expressed in chronic middle-ear pathologies and whether the entity of expression and the localization are correlated with the degree of the inflammatory reaction, thus suggesting that HMGB1 may play a crucial role in chronic inflammatory disorders of the middle ear, as already demonstrated in other airway diseases...

CASE SUMMARY: A 14-year-old female spayed cat was referred for recurrent otitis externa and unusual proliferative lesions in both ear canals. The affected pinnae and external ear canals were covered with large reddish-to-dark-brown verrucous and necrotic tissue. Friable material and exudates occluded both ear canals. Proliferative lesions developed in both ears 2-3 weeks before referral. The histopathological diagnosis from two biopsies obtained from the friable materials with endoscopic biopsy forceps was proliferative and necrotising otitis externa (PNOE)...

Dispersal of bacteria from a biofilm in the middle ear, serving as a bacterial reservoir, could explain the recurrent and chronic nature of chronic suppurative otitis media (CSOM). The objective of this study is to investigate if the same strains of bacteria could be detected in repeated episodes of otorrhea in CSOM. In a prospective case series at a primary healthcare clinic in Nuuk, Greenland, patients with more than 14 days of otorrhea were included consecutively. Samples for culturing and biofilm analysis were taken at enrollment and at any subsequent episode with otorrhea...

Primary immunodeficiency disorders (PIDs) have been described as diseases caused by one or more defects of the immune system. These patients are more likely to experience recurrent and/or severe infections and have a tendency to develop a wide range of complications. Respiratory diseases are the main and initial manifestation for the majority of PID patients and most common complication in this group of patients. Pulmonary complications present a significant cause of morbidity and also mortality among patients suffering from different forms of PIDs...
