Adenotonsillitis

BACKGROUND: Chronic adenoid infection by β-lactam-resistant Haemophilus influenzae type b (Hib) and biofilm formation contribute to adenoid hyperplasia. Middle ear disease consequently remains a critical issue in the pediatric population. The aim of this study was to investigate the correlation of Hib biofilm formation with middle ear effusion with adenoid hyperplasia (MEE-AH) and with pediatric obstructive sleep apnea (OSA). METHODS: A total of 384 patients with adenoidectomy from January 2008 to December 2012 were recruited in this investigation...

OBJECTIVE: The objective of this study was to prospectively evaluate the long-term efficacy of rapid maxillary expansion (RME) in a group of children with obstructive sleep apnea (OSA). MATERIAL AND METHOD: Thirty-one children diagnosed with OSA were involved in the study. These children had isolated maxillary narrowing and absence of enlarged adenotonsils at baseline. Twenty-three individuals (73% of the initial group) were followed up annually over a mean of 12 years after the completion of orthodontic treatment at a mean age of 8...

OBJECTIVE: To evaluate the role played by adenoids as a reservoir for infection in children assigned for adenoidectomy. METHODOLOGY: The study included 35 children with adenoid hypertrophy. All patients underwent clinical examination and adenoidectomy, adenotonsillectomy, or myringotomy with insertion of aeration tube according to indications. Surgical specimens were processed for conventional bacterial culture examination and to assay for biofilm formation. The obtained adherence values using spectrophotometer at 595 nm (OD595) was used to classify isolates according to its biofilm forming capacity...

BACKGROUND: Since adenoids may act as a reservoir for bacteria, they can cause ear infection, recurrent otitis and recurrent adenotonsillitis. Therefore, adenotonsillectomy is an efficient method for reducing the number and severity of subsequent infections. OBJECTIVES: This study aimed to determine the Chlamydophila pneumonia infection by serological tests and performing PCR in the adenoid tissue, in children undergoing adenoid surgery and compare the results with normal children...

BACKGROUND: There are insufficient data in the literature on the presence of Helicobacter pylori in tonsil and adenoid tissue of patients with only airway obstruction. This study examined the presence of H. pylori in surgical cases with airway obstruction or recurrent infection. AIMS: To investigate the relationship between H. pylori adenotonsillar colonisation and the frequency of adenotonsillitis and to compare paediatric and adult patients according to H. pylori tonsillar colonisation...

OBJECTIVE: To evaluate the oscillations on the viral detection in adenotonsillar tissues from patients with chronic adenotonsillar diseases as an indicia of the presence of persistent viral infections or acute subclinical infections. STUDY DESIGN: Cross-sectional prospective study. SETTING: Tertiary hospital. METHODS: The fluctuations of respiratory virus detection were compared to the major climatic variables during a two-year period using adenoids and palatine tonsils from 172 children with adenotonsillar hypertrophy and clinical evidence of obstructive sleep apnoea syndrome or recurrent adenotonsillitis, without symptoms of acute respiratory infection (ARI), by TaqMan real-time PCR...

AIM: The aim of current study is to investigate whether tonsillar and/or adenoid tissue of patients with chronic adenotonsillitis plays a reservoir role for Helicobacter pylori (H. pylori) or Helicobacter hepaticus (H. hepaticus). BACKGROUND: Recently, there have been arguments ragarding Helicobacter pylori (H. pylori) being reserved in adenotonsillar tissue. PATIENTS AND METHODS: This study was performed with 90 patients with the diagnosis of chronic tonsillitis and adenoid hypertrophy, mean age 36 ± 22, 32 (36%) female and 58(64%) male...

BACKGROUND: Previous reports have established the association of allergy with adenoidal and tonsillar hypertrophy, and adenotonsillar hypertrophy is a well known co-morbid factor in patients with allergic rhinitis. Very little is known about the association of history of allergy with timing of first presentation in adenotonsillitis patients. SETTING: Tertiary care urban referral hospital. STUDY DESIGN: Descriptive analysis of prospectively collected data...

BACKGROUND: Children with adenoid hypertrophy have been shown to harbor pathogenic bacteria in the nasopharynx despite antibiotics. Removal of the adenoid is associated with a reduction in the bacterial count. AIMS: The study was done to determine the bacteriology of the adenoid tissue in chronic adenotonsillitis and adenoid hypertrophy, and determine the antibiotic sensitivity of potential pathogens. MATERIALS AND METHODS: This is a descriptive study conducted on 100 patients aged between three and twelve years who underwent adenotonsillectomy/adenoidectomy...

BACKGROUND: Chronic rhinosinusitis (CRS) is a prevalent condition with underexplored risk factors. OBJECTIVES: We sought to determine CRS incidence and evaluate associations with a range of premorbid medical conditions for chronic rhinosinusitis without nasal polyps (CRSsNP) and chronic rhinosinusitis with nasal polyps (CRSwNP) using real-world clinical practice data. METHODS: Electronic health records data from 446,480 Geisinger Clinic primary care patients were used for a retrospective longitudinal cohort study for data from 2001-2010...

BACKGROUND: The aim of this study was to investigate whether in children with middle ear effusions (MEE), adenoid and tonsil tissues are associated with human bocavirus (HBoV). MATERIALS AND METHODS: A total of 124 patients (56 females (45.2%) and 68 males (54.8%)) with chronic adenotonsillitis and serous otitis media under the age of 15 were recruited. Two hundered four samples (113 adenoid (55.4%), 68 tonsil (33.3%), and 23 middle ear effusion (11.3%)) were analyzed for the presence of HBoV using polymerase chain reaction (PCR)...

Adenoid microbiota plays an important role in the development of various infectious and non-infectious diseases of the upper airways, such as otitis media, adenotonsillitis, rhinosinusitis and adenoid hypertrophy. Studies have suggested that adenoids could act as a potential reservoir of opportunistic pathogens. However, previous bacterial surveys of adenoids were mainly culture based and therefore might only provide an incomplete and potentially biased assessment of the microbial diversity. To develop an in-depth and comprehensive understanding of the adenoid microbial communities and test the 'pathogen reservoir hypothesis', we carried out a 16S rRNA based, culture-independent survey of bacterial communities on 67 human adenoids removed by surgery...

OBJECTIVES: Adenotonsillar hypertrophy (ATH) is the most common cause of upper airway obstruction in children. Severe upper airway obstruction may have an effect on chronic alveolar hypoventilation, which consequently may lead to right ventricle (RV) dysfunction induced by hypoxemic pulmonary vasoconstriction. The investigators aimed to study RV function and mean pulmonary artery pressure (mPAP) in patients with ATH who were undergoing adenotonsillectomy by using tissue Doppler echocardiography (TDE)...

OBJECTIVES: The aim of this study was to investigate serum paraoxonase, arylesterase activities along with determination of oxidative status via measurement of total oxidant status (TOS), total antioxidant status (TAS) and oxidative stress index (OSI) in children with recurrent adenotonsillitis during pre- and post-adenotonsillectomy period and to compare results with data from healthy subjects. METHODS: We performed a prospective controlled trial on adenoidectomy and/or tonsillectomy patients...

The objective of this study was to verify and describe, from a gender focus, the associations between gender and specific postoperative pain variables in pediatrics. This is a cross-sectional study of 77 children between 6 and 13 years of age (M=9 years; sd=2.2 years), ASA I and II, 77.9% from low-income classes, 68.8% boys and 32.8% girls. Data were collected on the first postoperative (1st PO) day through semi-structured interviews and four measurement scales. The main baseline diseases were adenotonsillitis and fractures...

Innate immunity involves the first line of the mucosal defense system. Homeostatic defense of the middle ear and Eustachian tube is maintained in part by molecules related to the innate immunity. The middle ear and tonsils are the organs related to the innate immunity. Recent attention has focused on the possibility that chronic otitis media and adenotonsillitis may represent a chronic infective state such as evidenced in conditions secondary to biofilms or small colony variants. The role of biofilms in the persistence of chronic mucosal-based ENT-related infections was first recognized in otitis media and adenotonsillitis...

OBJECTIVES: Biofilms are organized bacterial communities that are playing an increasing role in otolaryngological diseases such as chronic or recurrent middle ear otitis and adenotonsillitis. Various cultural techniques are available to detect biofilm-producing bacteria (BPB), but microbiological analysis of bioptic staining is the reference diagnostic procedure. To our knowledge, the accuracy of nasopharyngeal swabs in diagnosing BPB has never been assessed. STUDY DESIGN: A prospective study of diagnostic accuracy...

OBJECTIVE: Contradictory results have been reported regarding Helicobacter pylori (H. pylori) detection in adenotonsillar tissue. The aims of this study were to investigate whether adenotonsillar tissue of symptomatic children with chronic adenotonsillitis harbors the H. pylori organism, using two biopsy-based invasive methods namely; rapid urease test (RUT) and polymerase chain reaction (PCR) as well as blood serology and to compare the results obtained from each of these methods to the "gold standard"...

OBJECTIVES/HYPOTHESIS: To propose a definitive standard grading scale in the assessment of adenoid tissue in relation to size, position, and proximity to surrounding anatomic structures. This will allow for better clinical communications among practitioners when treating this pathology, a better understanding of its relationship and how it effects neighboring structures (eustachian tube and choanae), and allow for a more precise description of this tissue for the purpose of research data collection and analysis...

OBJECTIVE: The aim of this study is to determine the effect of adenoidectomy, tonsillectomy or adenotonsillectomy on growth. For this purpose, we prospectively reviewed the postoperative changes in serum levels of insulin-like growth factor-1 (IGF-1) and insulin-like growth factor binding protein-3 (IGFBP-3), weight and height in children that underwent adenoidectomy, tonsillectomy or adenotonsillectomy. METHODS: Ninety-six children with symptoms of sleep disordered breathing (SDB) or recurrent adenotonsillitis were enrolled to study...
