OBJECTIVE
The objective for this systematic review is to characterize clinical presentations of Bezold's abscesses to improve awareness and promote earlier diagnoses and prompt intervention in this increasingly rare otologic infection.
DATA SOURCES
Pubmed/Medline, CINAHL (EBSCOhost), and Web of Science articles in all languages were searched.
STUDY SELECTION
Inclusion criteria were that the article was either a case report, case series, or retrospective review with individual case data available. Non-English articles were excluded if they lacked an English language abstract and if that abstract lacked information on baseline demographics, clinical presentation, and management.
DATA EXTRACTION
Included studies were evaluated using fulltext review and demographics, etiology, microbiology, antibiotic usage, and surgical variables were collected.
DATA SYNTHESIS
Data were qualitatively synthesized, with means and averages obtained for all continuous variables.
CONCLUSIONS
Bezold's abscess remains a rare otologic infection, but they are relatively commonly associated with serious neurologic and systemic complications. Delay in diagnosis was a frequent commonality and diagnostic vigilance is tantamount in avoiding this sequelae. Aggressive surgical extirpation and long-term antibiotic treatment is recommended.

Review
Bezold's abscess is a deep neck abscess related to otomastoiditis. Due to the insidious clinical presentation, diagnosis can be extremely challenging, leading to delays in treatment and possible life-threatening complications. The literature currently provides a fragmented picture, presenting only single or small number of cases. The present study aims at examining our experience and the literature findings (based on PRISMA criteria) of 97 patients with Bezold's abscess, summarizing their epidemiology, pathogenesis, clinical presentation, imaging findings, and treatments. Bezold's abscess is found at any age, with overt male prevalence among adults. The clinical presentation, as well as the causative pathogens, are strikingly heterogeneous. Otomastoiditis and cholesteatoma are major risk factors. A clinical history of otitis is commonly reported (43%). CT and MRI are the main diagnostic tools, proving the erosion of the mastoid tip in 53% of patients and the presence of a concomitant cholesteatoma in 40%. Intracranial vascular (24%) or infectious (9%) complications have also been reported. Diagnosis might be easily achieved when imaging (CT) is properly applied. MRI has a limited diagnostic role, but it might be crucial whenever intracranial complications or the coexistence of cholesteatoma are suspected, helping to develop proper treatment (prompt antibiotic therapy and surgery).

Review
OBJECTIVE
The objectives of this review are to identify the types of materials with their associated complications and respective considerations when used to obliterate the mastoid cavity.
METHODS
A systematic search was performed across PubMed, Embase, Medline and Cochrane databases from January 2009 to January 2020 for randomized controlled trials and observational studies of patients that underwent mastoid obliteration. Studies that fulfilled the inclusion criteria were screened and scored according to the MINORS and relevance scores to determine final inclusion. Types of complications were grouped into minor and major complications based on the Clavien-Dindo classification.
RESULTS
Two thousand five hundred and seventy-eight ears were evaluated. There were a total of 165 (7.9%) minor and 142 (6.8%) major complications in the autologous group. Overall complication rate is 14.8%. The major complications were largely recurrent and residual disease requiring revision surgery. There were 10 (18.5%) minor complications and three (5.6%) major complications in the allogenic group. The cumulative complications risk is 24%. For the synthetic group, there were 39 (8.0%) minor and 34 (7.6%) major complications. The cumulative complication rate is 16.6%.
CONCLUSION
Current evidence on materials for mastoid obliteration has been evolving. Each material has its strengths and limitations. The trend over the last decade favours the use of autologous materials. The principle of using a material remains being cautious of not reimplanting skin that can lead to the development of a cholesteatoma. The choice of materials is dependent on patient factors as well as the surgeons' preference and experience.

Meta-Analysis
BACKGROUND
The objective of our study was to evaluate the efficacy of treatment options for the most frequently reported complications of acute mastoiditis in the English literature. PubMed, EMBASE, and The Cochrane Library were searched from database inception through March 29, 2019.
METHODS
Two independent reviewers (M.R.K., K.S.) evaluated search results for study inclusion. References cited in publications meeting inclusion criteria were reviewed. Twenty-three included studies were published from 1998 through 2018. Treatment efficacy was determined by comparing the change in number of complication subtypes in each treatment subgroup (medical, conservative, or surgical) from admission to discharge (range: 5-30 days) or postdischarge follow-up (range: 1-27.5 months) with a random effects model.
RESULTS
Among 733 identified articles, 23 met inclusion criteria. Of the 883 included patients, 203 were managed medically (23%), 300 conservatively (34%) and 380 surgically (43%). Conservative patients had more extracranial complications (ECC, P = 0.04) and intratemporal complications (IT, P = 0.04) at follow-up compared with medical patients. Medical patients had more total number of complications (TNC, P = 0.03), ECC (P = 0.02), and IT (P = 0.01) at discharge compared with surgical patients. Conservative patients had more of all complications except intracranial/extracranial abscess and "other" at discharge and follow-up compared with surgical patients.
CONCLUSIONS
There were larger reductions in TNC, ECC, and IT at discharge and follow-up among surgical patients compared with medical and conservative patients. There were greater reductions in TNC, ECC, IT, intracranial complications, subperiosteal abscess and lateral sinus thrombosis at discharge and follow-up among surgical patients compared with conservative patients.

Meta-Analysis Review
Clinical characteristics and an evaluation of predictors for a favourable outcome of Mycobacterium abscessus otomastoiditis: a systematic review and meta-analysis of individual participant data.
BACKGROUND
Otomastoiditis caused by Mycobacterium abscessus is rare, but its incidence has increased over the past decades and its optimal treatment remains unknown. This study aims to summarise the clinical and therapeutic features and find characteristics of patients with M. abscessus otomastoiditis associated with favourable treatment outcomes.
METHODS
We searched MEDLINE, Embase and Web of Science to identify studies including patients with M. abscessus otomastoiditis. A 1-stage individual patient data (IPD) meta-analysis was conducted. A 2-level mixed-effects linear regression model was provided for antimycobacterial treatment duration.
RESULTS
Twenty-three studies reported a total of 85 patients. Children possess a unique clinical profile including a history of ear infections, tympanostomy tube placement and antibiotic treatment. Antimycobacterial treatment was administered for 26 (interquartile range [IQR]: 15-35) weeks. Macrolides were prescribed in 98.8% of the cases. Surgery was performed in 80.5% of the cases, of which, 47.1% required revision surgery. Otalgia was a significant predictor (β = 9.3; P = .049) of antimycobacterial treatment duration.
CONCLUSIONS
Mastoid surgery (regularly requiring revision) and a multidrug regimen for a minimum of 6 months, including a minimum of 3 active agents, are most often needed to attain cure. The presence of otalgia significantly extends the treatment duration of M. abscessus otomastoiditis.

Review
OBJECTIVE
Acute mastoiditis is commonly attributed to infection. Rarely do clinicians encounter cases that do not respond to traditional antibiotics or surgical management. The goal of this study was to systematically review the literature to characterize diseases masquerading as acute infectious mastoiditis.
DATA SOURCES
PubMed, Embase, and Scopus.
REVIEW METHODS
A systematic review was performed to identify all publications that reported on diseases with presentations mimicking acute mastoiditis, defined as postauricular redness, swelling, and tenderness. We included clinical prospective studies, retrospective studies, and case series/reports. Exclusion criteria included non-English articles, letters/commentaries, abstracts, and review articles.
RESULTS
Out of 3339 results, 35 studies met final inclusion criteria. In children, 11 diseases were reported to mimic mastoiditis, including solid tumors, hematologic diseases, and autoimmune/inflammatory diseases. The most common disease in children was Langerhans cell histiocytosis, followed by rhabdomyosarcoma and acute myelogenous leukemia. In adults, 8 additional diseases were reported. The most common disease in adults was squamous cell carcinoma, followed by nasopharyngeal carcinoma and Langerhans cell histiocytosis. Presenting symptoms are reviewed, as well as characteristic radiographic, laboratory, and intraoperative features that may assist with diagnosis. A diagnostic algorithm for atypical cases of acute mastoiditis is proposed.
CONCLUSION
A small but significant group of diseases in children and adults can mimic acute mastoiditis. In such cases, history and examination alone may be insufficient to reach a diagnosis, and further investigation may be necessary. Otolaryngologists should always be mindful of the possibility that noninfectious pathologies may present with a constellation of symptoms similar to mastoiditis.

Review
BACKGROUND
Epithelial migration has been associated with the self-cleansing mechanism of the ear. The rate and pattern of epithelial migration in healthy and pathological ears are reviewed.
METHODS
Two authors independently screened articles over one month using the following search terms: epithelial migration, epithelial, tympanic membrane, external auditory canal and mastoidectomy cavity.
RESULTS
Ten studies were included. The fastest rate of epithelial migration was observed in the external auditory canal, with a mean of 144.75 μm per day, whereas the slowest epithelial migration was seen in post-mastoidectomy cavities, with a rate of 20 μm per day. Epithelial migration was present in both studies involving post-mastoidectomy cavities.
CONCLUSION
Epithelial migration is faster in healthy tympanic membrane than in pathological tympanic membrane. The rate of epithelial migration in the external auditory canal was higher in the pathological group than in the healthy group. Epithelial migration is present in post-mastoidectomy cavities.

Anterior fontanel is an integral element of an infant craniofacial system. There are six fontanels in the newborn skull, namely anterior, posterior, two mastoid, and two sphenoid fontanels. The anterior fontanel is the largest, prominent, and most important for clinical evaluation. Sex, race, genetics, gestational age, and region are the principal factors that influence anterior fontanel size. There exist inconclusive findings on the size of anterior fontanel in newborns. Therefore, this systematic review and meta-analysis aimed to determine the pooled mean size of anterior fontanel among term newborns and to identify the pooled mean difference of anterior fontanel size between males and females. PubMed/Medline, Google Scholar, Science Direct, JBI Library, embase, and Cochrane Library databases were systematically searched. All essential data were extracted using a standardized data extraction format. The heterogeneity across studies was assessed using the Cochrane Q test statistic, I test statistic, and -values. A fixed-effect model and random effect model were used to estimate the pooled mean size of anterior fontanel and the pooled mean difference between male newborns and female newborns, respectively. To deal with heterogeneity, sub-group analysis, meta-regression analysis, and sensitivity analysis were considered. JBI quality appraisal checklist was used to evaluate the quality of studies. In this meta-analysis, 8, 661 newborns were involved in twenty-six studies. Among studies, 13 conducted in Asia, 7 in Africa, 5 in America, and 1 in Europe. The pooled mean size of anterior fontanel was 2.58 cm (95% CI: 2.31, 2.85 cm). The pooled mean size of anterior fontanel for Asia, Africa, America, and Europe region was 2.49, 3.15, 2.35, and 2.01 cm, respectively. A statistically significant mean difference was detected between male and female newborns (D + L pooled MD = 0.15 cm, 95% CI: 0.02, 0.29 cm). The pooled estimate of this review does provide the mean value of the anterior fontanel size in the newborns. There was a statistically significant mean fontanel size difference between male and female newborns. Therefore, male newborns had a significantly larger mean size than female newborns.

Review
Streptococcus pneumoniae remains an important bacterial pathogen, particularly for young children in low- and middle-income countries. A systematic review was conducted of peer-reviewed literature from PubMed published as of May 13, 2020, to identify articles relevant to invasive pneumococcal disease, pneumonia, otitis media (OM), nasopharyngeal carriage (NPC), antimicrobial resistance (AMR), and vaccination coverage in Egypt, with particular focus on children ≤ 18 years of age. A total of 16 relevant articles spanning three decades were included in this review. Among studies reviewed, S. pneumoniae was the causative agent of meningitis in 21-30% of cases among hospitalized children between 1983 and 2003. One study showed that serotypes 6A and 6B predominated among meningitis cases of pediatric patients aged < 5 years. This review also revealed that S. pneumoniae was the most commonly identified bacterial pathogen of acute mastoiditis, a severe complication of acute OM, among children aged 9 months to 11 years. NPC studies showed that approximately 30% of Egyptian children were carriers of S. pneumoniae. AMR, especially to penicillin, continues to be a growing concern in low- and middle-income countries, including among Egyptian children. Several predominant serotypes were identified to be associated with penicillin resistance, such as 6B, 1, 19A, 23F, and 6A. Currently available pneumococcal vaccines (PCVs) such as PCV10 and PCV13 may provide coverage against the most prevalent circulating serotypes among Egyptian children. Comprehensive disease surveillance and immunization programs are needed to ensure that this vulnerable population is sufficiently protected against pneumococcal disease.

BACKGROUND
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections can affect the nervous system, triggering problems such as the Guillain-Barre Syndrome (GBS), an association that can bring complications to the patient.
OBJECTIVE
This scoping review aimed to clarify the clinical features and analyze patients with GBS associated with SARS-CoV-2 infection, looking at morbidity, mortality, and neurological outcomes.
SEARCH STRATEGY
The search was conducted through Medline, Web of Science, Embase, CINAHAL, Latin-American and Caribbean Literature in Health Sciences (LILACS), clinicaltrials.gov, SCOPUS, and the Cochrane Central Register of Controlled Trials.
SELECTION CRITERIA
Observational studies, published after 2019, describe patients with GBS associated with SARS-CoV-2 infection. There were no language restrictions while selecting the studies.
DATA COLLECTION AND ANALYSIS
Three authors, Kleyton Santos de Medeiros, Luíza Thomé de Araújo Macêdo, and Wederson Farias de Souza, independently screened the search results using titles and abstracts. Duplicate studies were excluded. The same authors then went through the entire text to determine whether the studies met the inclusion criteria. Discrepancies were resolved by other reviewers, Ana Paula Ferreira Costa, Ayane Cristine Sarmento, and Ana Katherine Gonçalves. Finally, the selection of the studies was summarized in a PRISMA flow diagram.
MAIN RESULTS
Main manifestations were fever, coughing, dyspnea, sore throat, ageusia, anosmia, and respiratory failure, in addition to paresthesia of the upper and lower limbs, tetraparesis, facial diplegia, areflexia, asthenia, mastoid pain, acute ataxia, fatigue, numbness, swallowing disorder, and moderate low back pain.
CONCLUSION
Coronavirus disease 2019 (COVID-19) can trigger the GBS, despite the few studies on this topic. Patients had clinical manifestations of COVID-19 infection and neurological manifestations characterizing GBS.
