Enzymatic study of tonsil tissue alkaline and acid phosphatase in children with recurrent tonsillitis and tonsil hypertrophy.

Objective: Indications for tonsillectomy in recurrent tonsillitis are defined according to the number of episodes of acute bacterial infections in a year. However, little is known about the tonsil immune competence status in patients presenting with recurrent tonsillitis with either hypertrophied or atrophied tonsils, or in patients presenting with obstructive sleep apnoea. In this study we examined the tonsil immune status in children with 3-5 acute recurrent infections a year and in children with obstructive sleep apnoea by comparing the activity of tonsil and adenoid tissue nonspecific alkaline and acid phosphatase.

Middle ear tuberculosis: diagnostic criteria.

Introduction: Tuberculous otitis is a diagnostic problem due to the difficulty to obtain microbiological, histomorphological and cytological confirmation of the disease.

Objective: Our objective was to compare clinical and radiological characteristic and development of otogenic complications in patients with tuberculous otitis and otitis with cholesteatoma as the most destructive form of chronic nonspecific otitis in the purpose of establishing the diagnostic criteria for tuberculous otitis.

Methods: Medical records of 12 patients with tuberculous otitis and 163 patients with cholesteatoma treated at the Institute of Otorhinolaryngology and Maxillofacial Surgery in Belgrade during the eight-year period were analyzed.

Alteration of adenoid tissue alkaline and acid phosphatase in children with secretory otitis media.

Objective: The role of pharyngeal lymphoid tissue in etiopathogenesis of secretory otitis is not yet defined. The influence of tonsillar and adenoid mass, weight, obstruction of naspharyngeal orrifitium, bacterial reservoire or some immunological events are of scientific interest. Tissue nonspecific alkaline phosphatase (TNAP) and acid phosphatase (ACP) are enzymes detected in lymphoid tissue, TNAP as characteristic of B cells, ACP as a characteristic of macrophages and folucullardentritic cells.
