In the past 130 years, many surgical procedures for turbinate reduction have been developed. We analyzed the long-term efficacy of 6 of these surgical techniques (turbinectomy, laser cautery, electrocautery, cryotherapy, submucosal resection, and submucosal resection with lateral displacement) over a 6-year follow-up period. We randomly divided 382 patients into 6 therapeutic groups and surgically treated them at the Department of Otorhinolaryngology of the University of Siena. After 6 years, only submucosal resection resulted in optimal long-term normalization of nasal patency and in restoration of mucociliary clearance and local secretory IgA production to a physiological level with few postoperative complications (p < .001). The addition of lateral displacement of the inferior turbinate improved the long-term results. We recommend, in spite of the greater surgical skill required, submucosal resection combined with lateral displacement as the first-choice technique for the treatment of nasal obstruction due to hypertrophy of the inferior turbinates.KEY WORDS -hypertrophy, inferior turbinate, submucosal resection.

Use of intranasal furosemide represents a valid therapeutic treatment in the prevention of chronic hyperplastic sinusitis with nasal polyposis.

The high percentage of biofilms in our specimens confirms the association between biofilms and CRS. Our data support the hypothesis that biofilm formation represents the latter phase of an inflammatory process that leads to complete epithelial destruction.

Nasal decongestants are the most powerful drugs in the reduction of nasal obstruction. Despite their large use, local and systemic adverse reactions are frequent. The authors focus on the pharmacology of these kinds of drugs in light of the most recent knowledge on nasal pathophysiology. The ultrastructural anatomy of nasal mucosa explains the complexity of the possible interactions between the sympathomimetics and imidazoles derivates, and the submucosal layer. Nasal obstruction is one of the most frequent clinical problems that otorhinolaryngologists encounter daily, both in adults and children. All possible predisposing conditions to nasal obstruction are documented along with the better ways to diagnose them through nasal functionality tests. Active anterior rhinomanometry, acoustic rhinometry and the determination of mucociliary transport time represent, together with nasal endoscopy, the gold standard for an accurate diagnosis and the follow-up of the patient to cure. An updated review of the most significant works in this field and the best treatment protocol to avoid adverse effects, such as rhinitis medicamentosa, are reported.

Descending necrotizing mediast initis is a rare diseas e that is usually caused by a spreading, diffuse irfiammatory reaction (phl eginon) to an odontoge nic inf ection or pe rito nsillar abscess. Rep ortedmortality rates rangefrom 25 to 40%. The use of antib iotics and advances in resuscitation pro cedures and critical care techniques have not essentially imp roved survival, and an effective treatm ent has not been clearly established. We rep ort the fi ndings ofour 10-y ear study of21 patients affected by phle gmon and/orfasciitis ofthe neck. The aim ofour contribution is to help define the clinical criteria and diagnos tic procedures that will impro ve the early diagno sis of mediastinal sepsis sec ondary 10 neckfasciitis and 10 suggest optima l treatment approaches. Our experience indicates tha t (1) cervical dra inage alane is sufficient for cases ofcervical phle gm on or mediastin al invo lvement that are limited to a single sup erior mediastinal sp ace and (2) thora cotomy and drainage oft nediastinal collec tions is necessary when mediastinal sepsis is mare extensive.

An important contribution to the variability of any proteome is given by the time dimension that should be carefully considered to define physiological modifications. To this purpose, whole saliva proteome was investigated in a wide age range. Whole saliva was collected from 17 preterm newborns with a postconceptional age at birth of 178-217 days. In these subjects sample collection was performed serially starting immediately after birth and within about 1 year follow-up, gathering a total of 111 specimens. Furthermore, whole saliva was collected from 182 subjects aged between 0 and 17 years and from 23 adults aged between 27 and 57 years. The naturally occurring intact salivary proteome of the 316 samples was analyzed by low- and high-resolution HPLC-ESI-MS platforms. Proteins peculiar of the adults appeared in saliva with different time courses during human development. Acidic proline-rich proteins encoded by PRH2 locus and glycosylated basic proline-rich proteins encoded by PRB3 locus appeared following 180 days of postconceptional age, followed at 7 months (±2 weeks) by histatin 1, statherin, and P-B peptide. The other histatins and acidic proline-rich proteins encoded by PRH1 locus appeared in whole saliva of babies from 1 to 3 weeks after the normal term of delivery, S-type cystatins appeared at 1 year (±3 months), and basic proline-rich proteins appeared at 4 years (±1 year) of age. All of the proteinases involved in the maturation of salivary proteins were more active in preterm than in at-term newborns, on the basis of the truncated forms detected. The activity of the Fam20C kinase, involved in the phosphorylation of various proteins, started around 180 days of postconceptional age, slowly increased reaching values comparable to adults at about 2 years (±6 months) of age. Instead, MAPK14 involved in the phosphorylation of S100A9 was fully active since birth also in preterm newborns.
