BACKGROUND: Hypertrophy of the lingual tonsil tissue in the adult patient is thought to contribute to the pathophysiology of obstructive sleep apnea. The underlying etiology of lingual tonsil hypertrophy (LTH) in the adult patient is unclear and likely multifactorial. Previous studies have suggested that the lingual tonsils may undergo compensatory hyperplasia post-tonsillectomy in children, although it is unknown if this occurs or persists into adulthood. The purpose of this study was to determine what factors are associated with LTH in a population of Canadian adults...

The system that protects body from infectious agents is immune system. On occasions, the system seldom reacts with some foreign particles and causes allergy. Allergies of the ear, nose and throat (ENT) often have serious consequences, including impairment and emotional strain that lowers the quality of life of patients. This is further responsible for the common cold, cough, tonsillitis, dermal infection, chest pain and asthma-like conditions which disturb one's day to day life. The present review enlightens some common ENT allergies which one can suffer more frequently in one's lifetime, and ignorance leads to making the condition chronic...

Both metal allergy and dental focal infection have been considered as causative factors for palmoplantar pustulosis, and several case reports described that the skin lesions were ameliorated after dental metal removal or dental infection control. However, limited data are available to evaluate the association of these factors with disease severity of palmoplantar pustulosis. This study is designed to analyze the clinical outcome of 85 palmoplantar pustulosis patients after dental infection control (n = 70), tonsillectomy (n = 6) and dental metal removal (n = 9)...

T follicular helper cells (Tfh cells), which are a prototypic subset of effector CD4(+) T cells, regulate the production of high-affinity antibodies by controlling B cells at initial and recall phases. Since the discovery of Tfh cells in human tonsils, many notable studies focusing on Tfh cells have clarified mechanisms underlying Tfh-cell-related physiological and pathological settings. Results of these studies revealed a chief regulatory function of BCL6 in Tfh cells and the involvement of Tfh cells in the pathogenesis of various disorders including autoimmune diseases, allergies and cancers...

BACKGROUND: Cysteinyl leukotriene receptor 1 and 2 (CysLTR1 and CysLTR2) are involved in allergic processes and play a role in adenotonsillar hyperplasia (AH). Clinically, only CysLTR1 may be blocked by montelukast. Our objective was to compare the expression of CysLTR1 and CysLTR2 in the B and T cells of hyperplasic tonsils of sensitized (SE) and control (NS) snoring children. METHODS: Sixty children, 5 to 10 years of age, referred for adenotonsillectomy, were divided into SE and NS groups, according to their responses to the skin-prick test...

Cysteinyl-leukotriene receptors 1 and 2 (CysLTR1 and 2) are related to allergic inflammatory responses. Recent studies demonstrated their role in lymphocyte division and maturation in the bone marrow. Few data are available about CysLTRs function in lymphocyte maturation in tonsils. The objectives of this study are to compare CysLTRs expression in peripheral blood lymphocytes with expression in maturating lymphocytes of hyperplasic tonsil and to check the influence of respiratory allergies in this process. Leukocytes of peripheral blood (PL) and hyperplasic tonsils of children were immunostained for CysLTR1, CysLTR2, CD3 (T cells), and CD19 (B cells) and read in flow cytometer...

BACKGROUND & AIM: High prevalence of acute otitis media (AOM) in children represents a combination of the factors developing eustachian tube dysfunction and higher susceptibility to upper respiratory tract infections in children. This disease is relatively prevalent in Iran and much cost is spent annually to treat it. This study investigated the effect of household parental smoking on development of AOM in children under 12 years. METHODS: In this case-control study all patients under the age of 12 years with AOM referring an ENT clinic in Shahrekord, southwest Iran between April 2014 and August 2014 were enrolled by convenience sampling...

BACKGROUND: Allergic rhinitis is characterized by eosinophil inflammation. Allergic inflammation may induce susceptibility to respiratory infections (RI). House dust mite (HDM) sensitization is very frequent in childhood. Allergen immunotherapy may cure allergy as it restores a physiologic immune and clinical tolerance to allergen and exerts anti-inflammatory activity. OBJECTIVE: This study investigated whether six-month high-dose, such as 300 IR (index of reactivity), HDM-sublingual immunotherapy (SLIT) could affect RI in allergic children...

BACKGROUND: Research on the origins and development of human IgE-expressing (IgE(+) ) cells is required for understanding the pathogenesis of allergy and asthma. These studies have been thwarted by the rarity of IgE(+) cells in vivo and the low frequency of class switch recombination (CSR) to IgE ex vivo. To determine the main source of IgE(+) cells, we investigated the relation between the phenotypic composition of tonsil B cells and the CSR to IgE ex vivo. METHODS: Human tonsil B cells were analyzed by flow cytometry (FACS) and cultured with IL-4 and anti-CD40 to induce CSR to IgE...

Otitis media with effusion (OME) is one of the most common causes of hearing loss (HL) in children. It has been reported that several factors such as eustachian tube dysfunction, insufficiencies in the aeration of the mastoid cells, allergies, immunity, and infections play an important role in the etiology of the disease. Little is known about the role of Helicobacter pylori (H. pylori) in extragastric diseases. Because of the near location of the nose, sinuses, tonsils, and adenoids to the eustachian tube and middle ear, we believe it is possible to have H...

OBJECTIVES: Although previous studies have assessed nonadherence to guidelines for prescribing antibiotic therapy in patients with pharyngotonsillitis (prescription of another antibiotic rather than one of first choice: amoxicillin and/or penicillin V, except in the case of penicillin allergy), none analyzed associated factors. Consequently, we conducted a study to assess the possible factors associated with the problem of nonadherence. METHODS: This cross-sectional study analyzed a sample of 417 patients with tonsillitis or pharyngotonsillitis treated with antibiotics during February 2014 in a Spanish region...

Surgery of the tonsils is still one of the most frequent procedures during childhood. Due to a series of fatal outcomes after hemorrhage in children in Austria in 2006, the standards and indications for tonsillectomy have slowly changed in Germany. However, no national guidelines exist and the frequency of tonsil surgery varies across the country. In some districts eight times more children were tonsillectomized than in others. A tonsillectomy in children under six years should only be done if the child suffers from recurrent acute bacterially tonsillitis...

Tonsil hypertrophy (TH) is very common in children. Previously, it has been reported that an inverse relationship exists between adenoid hypertrophy (AH) and allergic rhinitis (AR). This study aimed to investigate the possible relationship between tonsil volume and AR diagnosis in a group of children complaining of upper airways obstruction. Globally, 171 children (91 boys; mean age, 6.6 years) were studied. Clinical visit, nasal endoscopy, and skin-prick test were performed in all patients. TH and anterior nasal obstruction were graded using the Friedman's classifications...

No studies for the role of adenotonsillar hypertrophy in development of dentofacial abnormalities have been performed in Asian pediatric population. Thus, we aimed to investigate the relationship between adenotonsillar hypertrophy and dentofacial abnormalities in Korean children. The present study included consecutive children who visited a pediatric clinic for sleep-disordered breathing due to habitual mouth breathing, snoring or sleep apnea. Their palatine tonsils and adenoids were graded by oropharyngeal endoscopy and lateral cephalometry...
