BACKGROUND: Previous studies have suggested that B lymphocytes can be polyclonally activated by human cytomegalovirus (HCMV), and individuals infected by HCMV exhibit characteristic features of an autoimmunity disease. B cell-activating factor (BAFF) plays important roles in the survival and differentiation of B cells; however, few studies have examined the potential role of BAFF on B cells infected by HCMV. METHODS: HCMV virus strain (HCMV AD-169) was concentrated by normal methods and used to infect microbead-purified tonsil CD19+ B cells...

BACKGROUND: Concurrent chemoradiation (CCRT) and upfront surgery followed by adjuvant therapy both are recommended treatment options for patients with advanced stage squamous cell carcinoma (SCC) of the tonsil. To the authors' knowledge, the question of whether surgical-based treatments can achieve better survival compared with CCRT has never been compared in a clinical trial. The authors analyzed the National Cancer Data Base to measure the impact of different treatment modalities on overall survival (OS)...

Postoperative haemorrhage following tonsillectomy occurs in 5.98% of all cases with up to 10 deaths reported annually in Germany. When comparing tonsillectomy (TE) and tonsillotomy (TT), the same long-term frequency of ENT infections is displayed in children and young adults. However, taking postoperative haemorrhaging into account, TT is more favourable. Chronic tonsillitis is one of the most common indications for TE in the adult population; however, a histopathological characterization may reveal objective criteria and provide a foundation for routinely performing TT in adults too...

Objective Tonsillectomy is the most common operation performed in the otolaryngologic fields. Efforts have been made to reduce postoperative complications, and one of these is intracapsular tonsillectomy and adenoidectomy (ICTA), which leaves the tonsillar tissue with tonsillar capsule. This study aimed to evaluate intracapsular tonsillectomy compared with classical extracapsular tonsillectomy in terms of efficacy of the technique for managing obstructive sleep apnea (OSA) and reducing postoperative complications...

A high ambient temperature is a highly relevant stressor in poultry production. Heat stress (HS) has been reported to reduce animal welfare, performance indices and increase Salmonella susceptibility. Salmonella spp. are major zoonotic pathogen that cause over 1 billion of human infections worldwide annually. Therefore, the current study was designed to analyze the effect of heat stress on Salmonella infection in chickens through modulation of the immune responses. Salmonella Enteritidis was inoculated via gavage at one day of age (10(6)cfu/mL)...

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...

Prostaglandins (PGs) are bioactive lipid mediators generated from the phospholipids of cell membrane in response to various inflammatory signals. To understand the potential role of PGs in PG production itself during immune inflammatory responses, we examined the effect of PGE2, PGF2α, and beraprost on COX-2 expression using follicular dendritic cell (FDC)-like HK cells isolated from human tonsils. Those three PGs specifically augmented COX-2 protein expression in a dose-dependent manner after 4 or 8h of treatment...

Salmonella enterica is a well-known pathogen commonly acquired from the consumption of contaminated food. It has been estimated to affect millions of humans and cause hundreds of thousands of deaths per year globally. Pork, one of the most commonly consumed meats worldwide, has been identified as one of the main sources of human salmonellosis. In this study, we aimed to detect and characterize S. enterica from slaughtered swine and generate antimicrobial resistance profiles of select isolates. Tonsils and jejunum with mesenteric lymph nodes (MLN) were collected from a total of 240 swine from eight abattoirs (five accredited and three locally registered abattoirs) across Metro Manila...
