INTRODUCTION The quantity of lymphocytes in adenoid and their cooperation in immunological processes is dependent on proliferation process and their migration to the effectory places. The most important process provide for equilibrium between lymphocytes of tonsils is apopotosis. Special meaning in induction this process has Bcl-2 family proteins with can be divided into pro-apoptotic and anti-...
CONTEXT Bacteria within biofilms are resistant to host defenses and antibiotics. The presence of bacterial biofilms within the tissue and crypts of inflamed tonsils may explain the chronicity and recurrent characteristics of some forms of tonsillitis. OBJECTIVE To determine if microbial biofilms occur within clinically abnormal tonsils. DESIGN In this study, we evaluated the histomorphologi...
Background. Tonsillectomy is one of the treatment strategies for immunoglobulin A nephropathy (IgAN). The relationship between the indication of tonsillectomy and the size of palatine tonsils (PTs) in patients with IgAN remains controversial. Methods. This retrospective cohort study investigated 57 patients with IgAN who underwent tonsillectomy combined with steroid pulse therapy (SPT). They we...
The purpose of this investigation was to analyse whether there were any differences between children with and without enlarged tonsils with regard to the posture of the head, the hyoid bone, and the tongue. Twenty-two children with enlarged tonsils were compared with a matched normal control group. Of the children in the tonsil group, 59 per cent were mouth-breathers during the day and 82 per c...
OBJECTIVE To study biofilm formation on the epithelial surfaces of tonsils and adenoids in children undergoing adenotonsillectomy (T&A). DESIGN Prospective study. SETTING Tertiary academic hospital. PATIENTS Between September 2005 and August 2006, 76 patients (mean [SD] age, 5.7 [3.3] years; age range, 1-18 years; male-female ratio, 1.8:1) undergoing T&A to treat infection, obstruction, o...
OBJECTIVE Tonsillectomy is one of the most common surgical procedures in the United States, with more than 530,000 procedures performed annually in children younger than 15 years. Tonsillectomy is defined as a surgical procedure performed with or without adenoidectomy that completely removes the tonsil including its capsule by dissecting the peritonsillar space between the tonsil capsule and th...
Introduction: Most hospitals routinely examine microscopically all tonsillar and adenoid specimens from healthy pediatric patients complaining of recurrent infections or obstructive sleep apnea. Concern over missing the rare, unsuspected and significant diagnosis propagates this practice. Clinical examination for asymmetry could obviate the need for routine microscopic examination of tonsil and...
provided the original work is properly cited. CC The lingual tonsil, a normal component of Waldeyer’s ring, consists of lymphoid tissue located at the base of tongue [1]. A supraepiglottic mass like lingual tonsillar hypertrophy (LTH) is recognized as a risk factor for unanticipated failed tracheal intubation, and lingual tonsil hypertrophy has been reported to be a cause of difficult airway [1...
Objective: Sleep Disordered Breathing (USB) is one of the most common childhood disorders ranging from simple snoring to obstructive sleep apnea (OSA), and cause it adenotonsillar hypertrophy (ATH). Otitis Media with Effusion (OME) another important problem in children USB due ATH. The aim this study was evaluate possible risk factors for development EOM ATH.

The three-dimensional structure of capillary vessels in the human palatine tonsil using corrosion casting technique was investigated. The postcapillary venules and arterioles were distinguishable from the nuclear impressions on their walls. The configuration of vessels around cryptal micropores is similar to images obtained by a recently developed cryptscope. The palatine tonsil has no efferent...
