Tonsillectomy is the second most common operation undertaken in children in the United Kingdom, but the rate at which tonsillectomy is performed varies greatly across the Health Authorities. The reasons for the variation appear to be related to differences in local medical practice rather than differences in regional morbidity. This study was undertaken to compare the factors used to diagnose tonsillitis in children, the indications for tonsillectomy and the expected benefits of tonsillectomy in children by general practitioners, paediatricians and otolaryngologists. There was poor correlation between general practitioners, paediatricians and otolaryngologists in all study objectives. There appears to be no consistent clinical pathway by which children with recurrent tonsillitis are managed. The wide variation in tonsillectomy rates across the United Kingdom will probably continue until the decision-making process of doctors involved in the treatment of children with recurrent tonsillitis is better understood.
Otitis media with effusion (OME) is characterized by the accumulation of a viscous fluid rich in mucins in the middle ear cleft. There is increasing evidence that this fluid is the result of an inflammatory reaction and that nitric oxide (NO) is an important mediator in this reaction. The goblet cell line HT29-MTX produces principally MUC5AC, an important mucin in middle ear effusions, and thus is a good model for the study of mucus-secreting epithelia. Confluent cell cultures were trypsinized, subcultured and incubated with isosorbide dinitrate (ISDN), a NO donor, for 0.5, 1 and 2 h at a concentration of 1 mm and in concentrations of 0.01, 0.1, 0.5, 1 and 2 mm for 1 h. Experiments were performed four times. Mucin production was detected by a slot blot ELISA assay, using a monoclonal mouse antibody to human MUC5AC mucin. Statistical significance was tested using a one-way analysis of variance. NO donation by ISDN caused a consistent rise in mucin production above control. Maximal mucin production of 35% above control occurred at 1 h with 1 mm ISDN. Mucin production increased from 12% above control with 0.1 mm ISDN dinitrate to 45% above baseline with 2 mm ISDN. NO donation by ISDN results in an increase in mucus production, which is both dose and time related. This adds further evidence to an inflammatory model for mucus secretion in OME.
The causes of persistent cervical lymphadenopathy in children are many. Most are not significant, but some are life-threatening. Castleman's disease should be considered as a possible diagnosis in persistent childhood lymphadenopathy.
Spontaneous perforation of the oesophagus is an uncommon condition that almost invariably affects the thoracic oesophagus. We present an unusual case of perforation of the cervical oesophagus, in which an unsuspected ingested foreign body was ultimately found to be responsible.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
