Otitis in Patients With Community-Acquired Bacterial Meningitis: A Nationwide Prospective Cohort Study.

BACKGROUND: Otitis is commonly associated with community-acquired bacterial meningitis, but the role of ear surgery as treatment is debated. In this study, we investigated the impact of otitis and ear surgery on outcome of adults with community-acquired bacterial meningitis. METHODS: We analyzed episodes of adults with community-acquired bacterial meningitis from a nationwide prospective cohort study in the Netherlands, between March 2006 and July 2021. RESULTS: A total of 2548 episodes of community-acquired bacterial meningitis were evaluated. Otitis was present in 696 episodes (27%). In these patients the primary causative pathogen was Streptococcus pneumoniae (615 of 696 [88%]), followed by Streptococcus pyogenes (5%) and Haemophilus influenzae (4%). In 519 of 632 otitis episodes (82%) an ear-nose-throat specialist was consulted, and surgery was performed in 287 of 519 (55%). The types of surgery performed were myringotomy with ventilation tube insertion in 110 of 287 episodes (38%), mastoidectomy in 103 of 287 (36%), and myringotomy alone in 74 of 287 (26%). Unfavorable outcome occurred in 210 of 696 episodes (30%) and in 65 of 696 episodes was fatal (9%). Otitis was associated with a favorable outcome in a multivariable analysis (odds ratio 0.74; 95% confidence interval [CI] .59-.92; P = .008). There was no association between outcome and ear surgery. CONCLUSIONS: Otitis is a common focus of infection in community-acquired bacterial meningitis in adults, with S. pneumoniae being the most common causative pathogen. Presence of otitis is associated with a favorable outcome. Ear surgery's impact on the outcome of otogenic meningitis patients remains uncertain.

Intracranial complications of sinogenic and otogenic infections in children: an ESPN survey on their occurrence in the pre-COVID and post-COVID era.

BACKGROUND: COVID-19 pandemic is thought to have changed the epidemiology of some pediatric neurosurgical disease: among them are the intracranial complications of sinusitis and otitis (ICSO). According to some studies on a limited number of cases, both streptococci-related sinusitis and ICSO would have increased immediately after the pandemic, although the reason is not clear yet (seasonal changes versus pandemic-related effects). The goal of the present survey of the European Society for Pediatric Neurosurgery (ESPN) was to collect a large number of cases from different European countries encompassing the pre-COVID (2017-2019), COVID (2020-2021), and post-COVID period (2022-June 2023) looking for possible epidemiological and/or clinical changes. MATERIAL AND METHODS: An English language questionnaire was sent to ESPN members about year of the event, patient's age and gender, presence of immune-deficit or other favoring risk factors, COVID infection, signs and symptoms at onset, site of primary infection, type of intracranial complication, identified germ, type and number of surgical operations, type and duration of medical treatment, clinical and radiological outcome, duration of the follow-up. RESULTS: Two hundred fifty-four cases were collected by 30 centers coming from 14 different European countries. There was a statistically significant difference between the post-COVID period (129 children, 86 cases/year, 50.7% of the whole series) and the COVID (40 children, 20 cases/year, 15.7%) or the pre-COVID period (85 children, 28.3 cases/year, 33.5%). Other significant differences concerned the presence of predisposing factors/concurrent diseases (higher in the pre-COVID period) and previous COVID infection (higher in the post-COVID period). No relevant differences occurred as far as demographic, microbiological, clinical, radiological, outcome, morbidity, and mortality data were concerned. Paranasal sinuses and middle ear/mastoid were the most involved primary site of infection (71% and 27%, respectively), while extradural or subdural empyema and brain abscess were the most common ICSO (73% and 17%, respectively). Surgery was required in 95% of cases (neurosurgical and ENT procedure in 71% and 62% of cases, respectively) while antibiotics in 99% of cases. After a 12.4-month follow-up, a full clinical and radiological recovery was obtained in 85% and 84% of cases, respectively. The mortality rate was 2.7%. CONCLUSIONS: These results suggest that the occurrence of ICSO was significantly increased after the pandemic. Such an increase seems to be related to the indirect effects of the pandemic (e.g., immunity debt) rather than to a direct effect of COVID infection or to seasonal fluctuations. ICSO remain challenging diseases but the pandemic did not affect the management strategies nor their prognosis. The epidemiological change of sinusitis/otitis and ICSO should alert about the appropriate follow-up of children with sinusitis/otitis.

Incidence of pediatric tonsillitis, otitis and upper respiratory infectious entities in the pre and post COVID-19 quarantine eras.

BACKGROUND: At this point of the COVID-19 pandemic, with the worldwide loosening of health restrictions, there has been an observed jump in infectious load especially of the upper airways.Aims/Objectives: To shed light on children's immunity and potential health risks after the COVID-19 pandemic. METHODS: A retrospective chart review from May 2019 to January 2022. Pediatric patients with a discharge diagnosis suggestive of an upper respiratory or ENT infection were included. The sample was divided into three groups according to the date of presentation. RESULTS: A total 4356 patients were diagnosed with ENT infectious aetiology. The mean age was 4.69 years. The three periods studied were: Period-1 (May 2019-January 2020), period-2 (February 2020-April 2021) and period-3 (May 2021-January 2022). The distribution of adenoiditis and MEE is the same across all periods (p > .05). The incidence of URTI, AOM and tonsillitis were significantly highest during period-3 followed by period-1, which in turn was significantly higher than during period-2 (p < .05). The incidence of sinusitis was the highest during period-3 (p < .001). CONCLUSION: There seems to be a heightened susceptibility to acute infection in children after the pandemic.Significance: It is important to keep in mind the changes in microbiota and implement measures to promote healthy gut flora, timely vaccination, and prompt medical interventions.Summary BoxWhat is already known: We already know that quarantine has significantly decreased infectious load especially in children.This study adds an objective assessment of this decrease with an assessment of the infectious load post-quarantine.This study is a model for future pandemics on the importance of vaccinations and the importance of microbiota changes after pandemics.

Adult Patients With Bronchiectasis: A First Look at the US Bronchiectasis Research Registry.

OBJECTIVES: We sought to describe the characteristics of adult patients with bronchiectasis enrolled in the US Bronchiectasis Research Registry (BRR). METHODS: The BRR is a database of patients with non-cystic-fibrosis bronchiectasis (NCFB) enrolled at 13 sites in the United States. Baseline demographic, spirometric, imaging, microbiological, and therapeutic data were entered into a central Internet-based database. Patients were subsequently analyzed by the presence of NTM. RESULTS: We enrolled 1,826 patients between 2008 and 2014. Patients were predominantly women (79%), white (89%), and never smokers (60%), with a mean age of 64 ± 14 years. Sixty-three percent of the patients had a history of NTM disease or NTM isolated at baseline evaluation for entry into the BRR. Patients with NTM were older, predominantly women, and had bronchiectasis diagnosed at a later age than those without NTM. Gastroesophageal reflux disease (GERD) was more common in those with NTM, whereas asthma, primary immunodeficiency, and primary ciliary dyskinesia were more common in those without NTM. Fifty-one percent of patients had spirometric evidence of airflow obstruction. Patients with NTM were more likely to have diffusely dilated airways and tree-in-bud abnormalities. Pseudomonas and Staphylococcus aureus isolates were cultured less commonly in patients with NTM. Bronchial hygiene measures were used more often in those with NTM, whereas antibiotics used for exacerbations, rotating oral antibiotics, steroid use, and inhaled bronchodilators were more commonly used in those without NTM. CONCLUSIONS: Adult patients with bronchiectasis enrolled in the US BRR are described, with differences noted in demographic, radiographic, microbiological, and treatment variables based on stratification of the presence of NTM.

Reduction in emergency department visits for children's asthma, ear infections, and respiratory infections after the introduction of state smoke-free legislation.

Despite the benefits of smoke-free legislation on adult health, little is known about its impact on children's health. We examined the effects of tobacco control policies on the rate of emergency department (ED) visits for childhood asthma (N=128,807), ear infections (N=288,697), and respiratory infections (N=410,686) using outpatient ED visit data in Massachusetts (2001-2010), New Hampshire (2001-2009), and Vermont (2002-2010). We used negative binomial regression models to analyze the effect of state and local smoke-free legislation on ED visits for each health condition, controlling for cigarette taxes and health care reform legislation. We found no changes in the overall rate of ED visits for asthma, ear infections, and upper respiratory infections after the implementation of state or local smoke-free legislation or cigarette tax increases. However, an interaction with children's age revealed that among 10-17-year-olds state smoke-free legislation was associated with a 12% reduction in ED visits for asthma (adjusted incidence rate ratios (aIRR) 0.88; 95% CI 0.83, 0.95), an 8% reduction for ear infections (0.92; 0.88, 0.97), and a 9% reduction for upper respiratory infections (0.91; 0.87, 0.95). We found an overall 8% reduction in ED visits for lower respiratory infections after the implementation of state smoke-free legislation (0.92; 0.87, 0.96). The implementation of health care reform in Massachusetts was also associated with a 6-9% reduction in all children's ED visits for ear and upper respiratory infections. Our results suggest that state smoke-free legislation and health care reform may be effective interventions to improve children's health by reducing ED visits for asthma, ear infections, and respiratory infections.

Clinical and Genotypic Spectrum of Chronic Granulomatous Disease in 71 Latin American Patients: First Report from the LASID Registry.

AIM: We analyzed data from 71 patients with chronic granulomatous disease (CGD) with a confirmed genetic diagnosis, registered in the online Latin American Society of Primary Immunodeficiencies (LASID) database. RESULTS: Latin American CGD patients presented with recurrent and severe infections caused by several organisms. The mean age at disease onset was 23.9 months, and the mean age at CGD diagnosis was 52.7 months. Recurrent pneumonia was the most frequent clinical condition (76.8%), followed by lymphadenopathy (59.4%), granulomata (49.3%), skin infections (42%), chronic diarrhea (41.9%), otitis (29%), sepsis (23.2%), abscesses (21.7%), recurrent urinary tract infection (20.3%), and osteomyelitis (15.9%). Adverse reactions to bacillus Calmette-Guérin (BCG) vaccination were identified in 30% of the studied Latin American CGD cases. The genetic diagnoses of the 71 patients revealed 53 patients from 47 families with heterogeneous mutations in the CYBB gene (five novel mutations: p.W361G, p.C282X, p.W483R, p.R226X, and p.Q93X), 16 patients with the common deletion c.75_76 del.GT in exon 2 of NCF1 gene, and two patients with mutations in the CYBA gene. CONCLUSION: The majority of Latin American CGD patients carry a hemizygous mutation in the CYBB gene. They also presented a wide range of clinical manifestations most frequently bacterial and fungal infections of the respiratory tract, skin, and lymph nodes. Thirty percent of the Latin American CGD patients presented adverse reactions to BCG, indicating that this vaccine should be avoided in these patients.

Deformational plagiocephaly and craniosynostosis: trends in diagnosis and treatment after the "back to sleep" campaign.

BACKGROUND: In 1992, the American Academy of Pediatrics discouraged prone sleeping positions because of its association with sudden infant death syndrome. After this was an increased incidence of deformational plagiocephaly (DP). METHODS: A retrospective review was completed for patients with DP and craniosynostosis seen by plastic surgeons at a tertiary medical center during a 19-year period. Two groups of patients were evaluated before (1988-1995) and after (1996-2007) implementation of the "Back to Sleep" campaign. RESULTS: Of the 5169 patients, those with craniosynostosis (n = 279) had a mean age at initial evaluation before and after 1996 of 12.4 versus 5.6 months (P = 0.0008). There was a trend of decreasing age at initial evaluation and first surgery after 1996. For patients with DP (n = 4890), the mean age at initial evaluation before and after 1996 was 11.5 versus 6.0 months (P = 0.10). There was a trend of decreasing age at initial evaluation and DP correction after 1996. The majority of patients had right-sided DP (50.2%), followed by left-sided (24.7%) and bilateral (18.9%). There was no significant difference in DP correction rate (67% versus 87%) or the mean age that DP was corrected (12.8 versus 11.8 mo) before and after 1996. Compared with 1996 to 1999, there was a 214% and 390% increase in DP referrals from 2000 to 2003 and 2004 to 2007. For craniosynostosis, there was a 27% and 129% increase in referrals. CONCLUSIONS: The increasing incidence of DP since the Back to Sleep campaign is concerning, but a positive outcome is that patients are being referred and treated at a younger age.

Clinical characteristics of pediatric granular myringitis.

OBJECTIVE: To determine the clinical characteristics of children with granular myringitis. STUDY DESIGN: Case series with chart review of children with granular myringitis. SETTING: Tertiary care children's hospitals in Delaware and Florida. SUBJECTS AND METHODS: From July 1, 2006, to June 30, 2011, 15 patients were identified with granular myringitis based on International Classification of Diseases, Ninth Revision code 384.1 (10 male, 5 female; 10 left-sided, 5 right-sided). RESULTS: Average age at onset was 10 years (range, 4-18 years). Average length of symptoms was 21 months (range, 3-48 months). Thirteen of the 15 patients (87%) had myringotomy tube placement prior to diagnosis of myringitis, and 11 had a previous perforation (73%). Eleven myringoplasties were performed on 8 (53%) patients prior to the onset of granular myringitis (5 fascia, 2 fat, 2 cartilage, 1 paper patch, and 1 at an outside hospital that was unknown). A total of 27 otolaryngologic surgical procedures were done on 14 of 15 patients. Ten patients (67%) had audiometry performed, and 6 (40%) had ear cultures. Medical treatment included ciprofloxacin and dexamethasone otic drops in all patients, oral antibiotics in 4 patients, and additional topical agents in 8 patients. Two patients had laser resurfacing, and 1 patient had surgical curettage. Five patients had long-term remission, 8 had intermittent remission, and 2 had no remission of their symptoms. CONCLUSION: Granular myringitis is a chronic, recalcitrant disease typically preceded by myringotomy and tube placement or myringoplasty/tympanoplasty. Medical and surgical intervention is varied and often does not lead to permanent resolution of the disease.

Air quality improvement and the prevalence of frequent ear infections in children.

OBJECTIVE: To determine whether air quality influences the prevalence of pediatric frequent ear infections and respiratory allergy. STUDY DESIGN: Case-control study. SETTING: Academic medical center. SUBJECTS AND METHODS: The National Health Interview Survey child sample for the calendar years 1997 through 2006 was analyzed, extracting 12-month prevalence data for the following three disease conditions: frequent (>/=3 within 12 months) ear infections, respiratory allergy, and seizures (nonrespiratory control condition). Based on information from the Environmental Protection Agency, yearly historical data for the air quality criteria pollutants carbon monoxide, nitrous dioxide, sulfur dioxide, and particulate matter were tabulated. Graphical and linear regression analyses were conducted to determine the influence of air quality on each of the disease conditions. RESULTS: A total of 126,060 children were studied (51.4% male, mean age 8.6 yrs). Overall, the 12-month prevalence for three or more ear infections, respiratory allergy, and seizures was 6.6%, 11.7%, and 0.7%, respectively. Air quality steadily improved over the study period. Statistically significant positive regression coefficients were obtained for each of the criteria pollutants with ear infections (all P < 0.001), with regression coefficients ranging from 0.007 (particulate matter) to 11.2 (sulfur dioxide). For respiratory allergies, nonstatistically significant regression coefficients for the criteria pollutants were obtained (range <0.001-0.379, all P > or = 0.409). For the nonrespiratory condition seizures, nonsignificant regression coefficients were again identified (all P > or = 0.404). CONCLUSIONS: Better air quality is significantly associated with lower prevalence of pediatric frequent ear infections but is not associated with the prevalence of pediatric respiratory allergy. Improvements in air quality may be implicated in the decreased rates of pediatric ear infections over time.

Deep, respiratory tract and ear infections caused by Pseudallescheria (Scedosporium) and Microascus (Scopulariopsis) in Finland. A 10-year retrospective multi-center study.

Deep, respiratory tract and ear infections due to Microascaceae (Pseudallescheria, Scedosporium, Microascus or Scopulariopsis) were studied nationwide in Finland during 1993-2002. The data were based on 52,000 fungal cultures that represented about 50% of all such specimens in Finland and included all Finnish cases of profound immunosuppression. There were 39 cases that were re-evaluated as clinically significant, i.e., three pneumonias, two deep pedal infections and five wound infections, 11 sinusitis and 18 ear infections. The pedal infections and most pneumonias occurred in immunocompromised patients. Most cases, except the ear infections, were due to Pseudallescheria boydii. Two patients had lethal P. boydii pneumonia and a deep P. boydii infection of the foot contributed to a third lethal case. Two of the patients with lethal outcomes had received an allogeneic haematopoietic stem cell transplantation (AHSCT). Two patients with haematological malignancies were cured of deep site infections by a prolonged course of itraconazole. Wound, sinus and ear infections were cured or improved by local surgery or topical therapy. There were 0.8-1.7 cases of any type of infection per million inhabitants per year (MY) and 3.4 cases/1000 AHSCT. Mortality associated with Microascaceae in any type of patient was 0.06-0.12 MY.

Community-acquired bacterial meningitis in elderly patients: experience over 30 years.

Clinical characteristics, etiologies, evolution, and prognostic factors of community-acquired bacterial meningitis in elderly patients are not well known. To improve this knowledge, all episodes of community-acquired bacterial meningitis were prospectively recorded and cases occurring in patients >or=65 years old were selected. During the period 1977-2006, 675 episodes in adults (aged >or=18 yr) were recorded, with 185 (27%) in patients aged >or=65 years old; 76 were male and 109 were female, with a mean age of 73 +/- 6 years (range, 65-93 yr). Causative microorganisms were Streptococcus pneumoniae 74, Neisseria meningitidis 49, Listeria monocytogenes 17, other streptococcal 9, Escherichia coli 6, Haemophilus influenzae 4, Klebsiella pneumoniae and Staphylococcus aureus 2 each, Capnocytophaga canimorsus and Enterococcus faecalis 1 each, and unknown in 20. On admission 91% had had fever, 32% were in a coma (Glasgow Coma Scale or=65 yr), who showed a higher frequency of diabetes and malignancy as underlying disease; pneumonia, otitis, and pericranial fistula as predisposing factors; and S. pneumoniae and L. monocytogenes as etiology. There were also differences in clinical presentation, complications, sequelae, and mortality. Factors independently related with mortality were age, pneumonia as a predisposing factor, coma on admission, and heart failure and seizures after therapy. Dexamethasone therapy was a protective factor. In conclusion, bacterial meningitis in elderly patients is associated with greater diagnostic difficulties and neurologic severity and more complications, as well as with increased mortality. Antiseizure prophylaxis might be useful in these patients.

[Epidemiological analysis of the incidence of invasive and non-invasive pneumococcal infections in different population groups].

Despite modern achievements in diagnostics and treatment, invasive and non-invasive pneumococcal infections remain a topical public health problem. To a large extent, it is connected with the absence or inconsistence of evidence-based information on this kind of infection. In this paper, retrospective analysis of the incidence of pneumococcal infections was performed on the basis of medical records available today in every health institution; the peculiarities of their nosologic structure were revealed. Among invasive forms, pneumococcal pneumonias prevailed (50.06%); apparent hypodiagnostics of pneumococcal meningitis was noted (only 4.02%). Among non-invasive forms, acute otitis with various complications prevailed (47.5%), acute sinusitis was registered in 37.5% of cases, and other ENT diseases (sphenoiditis, frontitis, ethmoiditis, etc.) were registered in 15% of cases. The study found that the main risk factors in these patients had been different ENT diseases which the patients had suffered from during the previous three months before the actual illness. Thus, the necessity for the development and perfection of techniques of microbiological diagnostics and the development of epidemiological control methods on their basis are obvious.

Duration of breastfeeding, daycare, and physician visits among infants 6 months and younger.

PURPOSE: To describe the association between duration of breastfeeding and an illness requiring a visit to a health care provider within the past 30 days (IRHP) among infants

A longitudinal analysis of infant morbidity and the extent of breastfeeding in the United States.

BACKGROUND: Studies on the health benefits of breastfeeding in developed countries have shown conflicting results. These studies often fail to account for confounding, reverse causality, and dose-response effects. We addressed these issues in analyzing longitudinal data to determine if breastfeeding protects US infants from developing diarrhea and ear infections. METHODS: Mothers participating in a mail panel provided information on their infants at ages 2, 3, 4, 5, 6, and 7 months. Infants were classified as exclusively breastfed; high, middle, or low mixed breast- and formula-fed; or exclusively formula-fed. Diarrhea and ear infection diagnoses were based on mothers' reports. Infant age and gender; other liquid and solid intake; maternal education, occupation, and smoking; household size; family income; and day care use were adjusted for in the full models. RESULTS: The risk of developing either diarrhea or ear infection increased as the amount of breast milk an infant received decreased. In the full models, the risk for diarrhea remained significant only in infants who received no breast milk compared with those who received only breast milk (odds ratio = 1.8); the risk for ear infection remained significant in the low mixed feeding group (odds ratio = 1.6) and among infants receiving no breast milk compared with those who received only breast milk (odds ratio = 1.7). CONCLUSIONS: Breastfeeding protects US infants against the development of diarrhea and ear infection. Breastfeeding does not have to be exclusive to confer this benefit. In fact, protection is afforded in a dose-response manner. The more breast milk an infant receives in the first 6 months of life, the less likely that he or she

[Tuberculosis of the otorhinolaryngologic region: laryngeal and extra-laryngeal forms]. / Tuberculosis del área otorrinolaringológica: formas laríngeas y extralaríngeas.

BACKGROUND: The aim of the study was to assess all patients with ENT symptoms whose histologic and/or microbiologic diagnosis confirmed tuberculosis. METHODS: All the anatomopathologic studies performed in the ENT unit in the authors' hospital in which the presence of acid-alcohol resistant bacilli were observed. All cases of cervical adenitis were not included. RESULTS: Eighteen patients with the following localizations were studied: 14 laryngeal tuberculosis and 4 extra-laryngeal tuberculosis (2 oropharyngeal, 1 otic and 1 sinusal). In the laryngeal forms, all patients were male except for one, and all were smokers. The duration of the symptoms was greater than 3 months in all the cases. Unilateral cord involvement was most commonly found, and in 2 cases this was associated with carcinoma of the vocal cord. Twenty-nine percent did not present with coincident pulmonary tuberculosis. None of the extra-laryngeal forms showed pulmonary involvement. All the patients were women and only 1 was smoker, the symptomatology was greater than 3 months in all cases and all required biopsy for achieving diagnosis. The evolution with medical treatment was favorable in all cases. During the same time period, 2300 cases of pulmonary tuberculosis were diagnosed in the authors' hospital. CONCLUSIONS: Tuberculosis of the upper respiratory tract is infrequent. Pulmonary involvement is common, although in this series this was only found in 71% of all laryngeal forms. Diagnosis is difficult, except in cases of coinciding pulmonary involvement and usually requires surgery for biopsy. Response to medical treatment is usually good.

Revision tympanoplasty: surgical findings and results in Riyadh.

A report on the surgical findings and long-term results of 68 revision tympanoplasties performed at King Abdul Aziz University Hospital over a period of 7 years is presented. Temporalis fascia was used in all operations, with an overall success rate of 85% of graft take up, with significant improvement of hearing in the majority of cases. The causes of immediate failure were found to be due to faulty surgical techniques, however most of the late reperforations were due to infections and in some to atrophy of the graft. It is concluded that better surgical technique and improvement of medical facilities in most rural areas are of utmost importance in Saudi Arabia.

Private medical insurance and elective surgery during early childhood.

The relationship between private medical insurance coverage and rates of elective ENT surgery was studied in a birth cohort of seven-year-old children. This analysis suggested that private medical insurance coverage was associated with differences in patterns of elective surgery with children whose families were covered by insurance being more likely to receive elective ENT surgery by seven years and far more likely to receive this treatment at a private hospital. These trends persisted when the child's history of ear/throat infections and family social and economic background were taken into account statistically.
