Congenital Cholesteatoma in Adults-Interesting Presentations and Management

AbstractTo report a series of adult patients diagnosed with congenital cholesteatoma (CC) with respect to symptoms, different varieties of presentation, surgical findings and approach used, complications and the postoperative results. A retrospective chart review of adult cases of CC who were treated in the period from January 2014 –2017 was carried out in a tertiary care center. Levenson’s criteria were used for diagnosis. Diagnosis was confirmed by imaging and intraoperatively. Postoperative results and complications were also analyzed. Six adult cases of CC were studied with a mean follow up of 10 months. Interesting p resentations included otitis media with effusion, non-resolving facial nerve palsy, post aural discharge and meningitis. It included 3 cases of petrous apex cholesteatoma, 2 patients with cholesteatoma involving both the middle ear and mastoid and 1 patient with mastoid cholesteatoma. The operative procedures included canal wall up mastoidectomy (1 patient), atticotomy (1 patient), canal wall down mastoidectomy (1 patient), translabyrinthine and transotic excision of mass with blind sac closure (2 patients) and partial labyrinthectomy (1 patient). Complications encountered during surgery were cerebrospinal fluid leak and worsening of hearing in 2 patients and 1 patient respectively. CC can have variety of interesting presentations in adult population and they may or may not have the classical white mass behind the tympanic membrane. Appropri...

This study sought to quantify the effect of AMR on treatments for pediatric pneumococcal disease in Ethiopia. We developed the DREAMR (Dynamic Representation of the Economics of AMR) model that simulated children younger than 5 years who acquire pneumococcal disease (pneumonia, meningitis, and acute otitis media) and seek treatment from various health facilities in Ethiopia over a year. We examined the AMR levels of three antibiotics (penicillin, amoxicillin, and ceftriaxone), treatment failures, and attributable deaths. We used a cost-of-illness method to assess the resulting economic impact of AMR from a societal perspec...

In this study, we characterized the transcriptome and metabolome of ΔcadA and identified specific mechanisms that could explain the regulatory role of polyamines in pneumococcal CPS biosynthesis. Our data indicate that impaired polyamine synthesis impacts galactose to glucose interconversion via the Leloir pathway which limits the availability of UDP-galactose, a precursor of serotype 4 CPS, and UDP-N-acetylglucosamine (UDP-GlcNAc), a nucleotide sugar precursor that is at the intersection of CPS and peptidoglycan repeat unit biosynthesis. Reduced carbon flux through glycolysis, coupled with altered fate of glycolytic...

Publication date: Available online 7 August 2019Source: Journal of Structural BiologyAuthor(s): Kornelia M. Mikula, Robert Kolodziejczyk, Adrian GoldmanAbstractThe gram-negative bacterium Moraxella catarrhalis infects humans exclusively, causing various respiratory tract diseases, including acute otitis media in children, septicaemia or meningitis in adults, and pneumonia in the elderly. To do so, M. catarrhalis expresses virulence factors facilitating its entry and survival in the host. Among them are the ubiquitous surface proteins (Usps): A1, A2, and A2H, which all belong to the trimeric autotransporter adhesin family. ...

Conclusions: Children with OM-associated BM were prone to many problems, such as being especially ill at presentation, undergoing a difficult clinical course and showing a higher risk of complicated or fatal outcome. HIV infection and malnutrition were common in children with otorrhea, which was also associated with low socioeconomic status.

Authors: Kazdaglis G, Lucin J, Kertat K, Persis S Abstract Streptococcus pneumoniae is a Gram-positive, alpha-hemolytic, facultative anaerobic coccus. It is the most common cause of community acquired pneumonia in adults and infants, and a major cause of morbidity and mortality. It is also a frequent cause of otitis media and sinus infections. It spreads through close person-to-person contact via respiratory droplets. It presents as pneumonia, bacteremia, or meningitis. PMID: 31184099 [PubMed - as supplied by publisher]

Discussion Facial nerve palsy has been known for centuries, but in 1821 unilateral facial nerve paralysis was described by Sir Charles Bell. Bell’s palsy (BP) is a unilateral, acute facial paralysis that is clinically diagnosed after other etiologies have been excluded by appropriate history, physical examination and/or laboratory testing or imaging. Symptoms include abnormal movement of facial nerve. It can be associated with changes in facial sensation, hearing, taste or excessive tearing. The right and left sides are equally affected but bilateral BP is rare (0.3%). Paralysis can be complete or incomplete at prese...

In this study, mouse peritoneal neutrophils from C57BL/6 WT and inflammasome components knockout mice were infected by S. pneumoniae in vitro. The results showed that NLRP3 inflammasome is critically involved in neutrophil IL-1β secretion, while the AIM2 and NLRC4 inflammasomes were dispensable. Moreover, the upstream kinase, JNK, modulates ASC oligomerization and consequent caspase-1 activation and IL-1β secretion. Additionally, neutrophil serine proteases also participate in IL-1β secretion by mediating ASC oligomerization and caspase-1 activation. Taken together, these findings indicated that bo...

ConclusionsAny difference in price between PHiD-CV and PCV13 is expected to be the key driver of vaccine choice for preventing childhood pneumococcal disease in Turkey. At price parity, PHiD-CV use is likely to be a dominant strategy over the use of PCV13.

Abstract We have reported a case of mastoiditis which progressed to meningitis in a 16-year old male patient. CSF (cerebrospinal fluid) anaerobic culture revealed four species of isolated anaerobic bacteria. This is the first case in the literature in which a patient survived childhood polymicrobial anaerobic meningitis diagnosed by MALDI-TOF MS (Matrix Assisted Laser Desorption Ionization - Time of Flight Mass Spectrometry) .
