The effect of pneumococcal conjugated vaccines on occurrence of recurrent acute otitis media among infants diagnosed with acute otitis media at an age younger than 2 months. Eur J Pediatr 2023:10.1007/s00431-023-04918-0. [PMID: 37052673 DOI: 10.1007/s00431-023-04918-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/28/2023] [Revised: 02/28/2023] [Accepted: 03/02/2023] [Indexed: 04/14/2023]
Abstract
To examine the impact of pneumococcal conjugate vaccines (PCV) on the occurrence of recurrent acute otitis media (rAOM) among infants diagnosed with an early acute otitis media (AOM) episode. Retrospective cohort study of pediatric patients with a first episode of AOM at an age < 2 months. Data included clinical, demographic, and microbiological findings at the first AOM episode. In addition, a 5-year follow-up after the patient's first episode was completed from the medical records. This information included documentation of rAOM episodes and complications of AOM (hearing loss, speech disturbance, mastoiditis, and tympanic membrane perforation) and of ear-related surgical procedures (ventilation tube placement, adenoidectomies, and mastoid surgery). Two groups were studied: patients diagnosed between 2005 and 2009 (representing the unvaccinated group, group 1) and those diagnosed in 2010-2014 (the vaccinated group, group 2). A total of 170 infants were diagnosed with a first AOM episode at an age < 2 months; 81 of them belonged to group 1 and 89 to group 2. Streptococcus pneumoniae was isolated in the middle-ear fluid in the first AOM episode in 48.1% of the patients in group 1 and in 30.3% in group 2 (P = 0.0316). 49/81 (60.5%) infants in group 1 were diagnosed with rAOM versus 39/80 (43.8%) in group 2 (P = 0.0298). No statistical differences were found between the groups with respect to long-term complications or need for surgery later in life. Conclusion: Our study showed a significant decrease in the occurrence of rAOM in infants diagnosed with AOM during the first 2 months of life and timely immunized with PCVs following this initial AOM episode. What is Known: • 30% of children experience recurrent AOM (rAOM) at the first year of life. The earlier the age of the first AOM, the greater the risk for future complications. • After the introduction of PCVs, the overall pneumococcal AOM incidence declined. We investigated the future effect of PCVs on rAOM occurrence, when administered after the first AOM episode. What is New: • A retrospective cohort of 170 infants with a first AOM episode at an age <2 months and followed for 5 years, showed a significant decrease (28.0%) of rAOM in immunized infants following the initial AOM episode. • Our findings supplement previous data suggesting that the widespread PCVs use prevents rAOM by preventing early AOM and emphasize the importance of timely administration of the PCVs.

Evaluation of Clinical Graded Treatment of Acute Nonsuppurative Otitis Media in Children with Acute Upper Respiratory Tract Infection. Neural Plast 2021; 2021:5517209. [PMID: 33883993 PMCID: PMC8041539 DOI: 10.1155/2021/5517209] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2021] [Revised: 02/23/2021] [Accepted: 03/12/2021] [Indexed: 11/28/2022] Open
Abstract
Objective To treat children with acute nonsuppurative otitis media induced by acute upper respiratory tract infection of varying severity and evaluate its therapeutic effects. Materials and Methods Patients from the emergency department with acute nonsuppurative otitis media were followed up between September 2015 and December 2018. A total of 420 patients were classified into grades I to III according to tympanic membrane intactness and systemic reactions and treated according to grading. Results Grade I patients showed no significant difference in the recovery of acute symptoms whether antibiotics are used or not. Grade II patients, after 3 months of follow-up, showed no tympanic membrane perforation, and 9 cases of binaural B-type children did not improve but were cured by operation. In grade III patients, after treatment for 4 hours in the experimental group 3, the earache subsided, 1 case had tympanic membrane perforation, and the patients recovered after 2 weeks (64/92) and after 3 months (28/92) of drug treatment. After treatment for 4 h in the control group 3, the earache eased, and 3 patients developed tympanic membrane perforation and were treated for 3 months. 4 binaural B-type children did not improve but recovered after surgical treatment. Conclusion Grade I patients could be closely followed up by clinical observation. For anti-inflammatory patients with grade II disease, treatment has therapeutic significance. For patients with grade III, some patients still have TMP, but the use of cephalosporin third-generation drugs plus an appropriate amount of hormone therapy is effective in reducing symptoms and tympanic local reactions.

Abstract
There are a limited number of documented cases of acute otitis media (AOM) in preterm infants while hospitalized in the neonatal intensive care unit (NICU). We present a case of a former 26 weeks old infant who at 29 weeks, 6 days postmenstrual age presented with acute signs and symptoms of systemic sepsis subsequently found to be secondary to AOM with purulent ear drainage. The patient received a septic evaluation, including urine, blood, and cerebrospinal fluid studies. Treatment included intravenous antibiotics with full resolution of symptoms. AOM in extreme preterm infants is multifactorial, with leading causes that include prematurity, the use of oropharyngeal and nasogastric tube placement and endotracheal intubation, eustachian tube dysfunction, and a distinct immune response. To our knowledge, there is not another published case of AOM of a preterm baby while in the NICU.

Quantitative definition of neurobehavior, vision, hearing and brain volumes in macaques congenitally exposed to Zika virus. PLoS One 2020; 15:e0235877. [PMID: 33091010 PMCID: PMC7580995 DOI: 10.1371/journal.pone.0235877] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2020] [Accepted: 10/05/2020] [Indexed: 12/14/2022] Open
Abstract
Congenital Zika virus (ZIKV) exposure results in a spectrum of disease ranging from severe birth defects to delayed onset neurodevelopmental deficits. ZIKV-related neuropathogenesis, predictors of birth defects, and neurodevelopmental deficits are not well defined in people. Here we assess the methodological and statistical feasibility of a congenital ZIKV exposure macaque model for identifying infant neurobehavior and brain abnormalities that may underlie neurodevelopmental deficits. We inoculated five pregnant macaques with ZIKV and mock-inoculated one macaque in the first trimester. Following birth, growth, ocular structure/function, brain structure, hearing, histopathology, and neurobehavior were quantitatively assessed during the first week of life. We identified the typical pregnancy outcomes of congenital ZIKV infection, with fetal demise and placental abnormalities. We estimated sample sizes needed to define differences between groups and demonstrated that future studies quantifying brain region volumes, retinal structure, hearing, and visual pathway function require a sample size of 14 animals per group (14 ZIKV, 14 control) to detect statistically significant differences in at least half of the infant exam parameters. Establishing the parameters for future studies of neurodevelopmental outcomes following congenital ZIKV exposure in macaques is essential for robust and rigorous experimental design.

Abstract
AIM The diagnosis of infantile colic is based on excessive crying. However, several causal factors can account for this disconcerting, nonspecific symptom. The main aim of this study was to investigate a possible association between excessive crying during the first 6 months of life and subsequent ear problems. METHODS Data from a cohort study of 26 983 Danish children were used. Mothers participated in four telephone interviews and one questionnaire and provided information on crying in the first 6 months of life and ear symptoms at the ages of 6 months, 18 months and 7 years. RESULTS There was a statistically significant association between excessive crying in infancy and subsequent ear symptoms. A gradual increase in subsequent ear problems was seen with increasing crying time at all the data collection times. CONCLUSIONS The results of this study suggest a possible link between excessive crying and ear infections. Whether such a link is causal or due to common underlying factors is still unknown. We recommend thorough ear examinations in children with symptoms compatible with infantile colic.

Pathological features in the LmnaDhe/+ mutant mouse provide a novel model of human otitis media and laminopathies. THE AMERICAN JOURNAL OF PATHOLOGY 2012; 181:761-74. [PMID: 22819531 DOI: 10.1016/j.ajpath.2012.05.031] [Citation(s) in RCA: 19] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/29/2012] [Revised: 05/07/2012] [Accepted: 05/17/2012] [Indexed: 11/21/2022]
Abstract
Genetic predisposition is recognized as an important pathogenetic factor in otitis media (OM) and associated diseases. Mutant Lmna mice heterozygous for the disheveled hair and ears allele (Lmna(Dhe/+)) exhibit early-onset, profound hearing deficits and other pathological features mimicking human laminopathy associated with the LMNA mutation. We assessed the effects of the Lmna(Dhe/+) mutation on development of OM and pathological abnormalities characteristic of laminopathy. Malformation and abnormal positioning of the eustachian tube, accompanied by OM, were observed in all of the Lmna(Dhe/+) mice (100% penetrance) as early as postnatal day P12. Scanning electronic microscopy revealed ultrastructural damage to the cilia in middle ears that exhibited OM. Hearing assessment revealed significant hearing loss, paralleling that in human OM. Expression of NF-κB, TNF-α, and TGF-β, which correlated with inflammation and/or bony development, was up-regulated in the ears or in the peritoneal macrophages of Lmna(Dhe/+) mice. Rugous, disintegrative, and enlarged nuclear morphology of peritoneal macrophages and hyperphosphatemia were found in Lmna(Dhe/+) mutant mice. Taken together, these features resemble the pathology of human laminopathies, possibly revealing some profound pathology, beyond OM, associated with the mutation. The Lmna(Dhe/+) mutant mouse provides a novel model of human OM and laminopathy.
