It discusses biomineralization modulators, anti-mycobacterial agents, underwater adhesives, mucoadhesive drug and gene delivery agents, and cell encapsulants fabricated using PASA derived PELs.Tonsil hypertrophy (TH) and adenoid hypertrophy (AH) are very common in children. Adenoid is visible only by endoscopy. This study investigated the possible relationship between the tonsil and adenoid volume and the possible prediction of adenoid size. Globally, 991 children (461 females, 530 males, mean age 6.2 ± 2.3 years), complaining persistent upper airway obstruction, were consecutively visited at an otorhinolaryngological unit. TH was significantly (p less then 0.0001) associated with AH and tonsil volume predicted adenoid size. This outcome could have relevance in clinical practice as adenoid are evaluable only by endoscopy, so tonsil assessment could mirror adenoid volume.Children with recurrent respiratory infections (RRI) represent a social issue for the economic burden and the familiar negative impact. Bacteriotherapy, such as the administration of "good" bacteria, is a new therapeutic strategy that could be potentially effective in preventing infections. The current study tested the hypothesis of preventing RRI by oral Bacteriotherapy in a real-life setting. This open study was conducted in an outpatient clinic, enrolling 51 children (27 males, mean age 4.8 ± 2.6 years) suffering from RRI. Children were treated with an oral spray, containing Streptococcus salivarius 24SMB and Streptococcus oralis89a (125 x 109 CFU/g), 2 puffs per os once/day for 30 consecutive days; this course was repeated for 3 months. The evaluated parameters were RI number and school absences reported in the current year; these outcomes were compared with those r
