Fourteen children aged between 6 months and 7 years (mean age = 3.5 years) were treated by CO2 broncholaser in the ENT Department of Trousseau Hospital. Three groups of diagnostic indication were identified: 1. Granulomas treated after mucosal trauma (tracheotomy, foreign body). 2. Granulomas due to pulmonary and/or lymph node tuberculosis. 3. Adhesions and stenosis secondary to neonatal ventilation. The operative and anesthetic technique is described in detail, together with any possible adverse events. The CO2 broncholaser appears to be a technique of choice in this age group, in which the narrowness of the airways makes any endoscopic procedure difficult. The broncholaser allows the early treatment of obstructive tracheobronchial pathology with its risks of severe ventilatory sequelae.

Application of antimicrobial chemicals is a general procedure in the cleaning and disinfection of food-contacting surfaces. Adhesion to glass surfaces and chemically induced detachment of Pseudomonas fluorescens ATCC 13525(T) were studied in situ, under flow conditions, in a well-controlled parallel plate flow chamber (PPFC). Ortho-phthalaldehyde (OPA) and cetyltrimethyl ammonium bromide (CTAB) were applied separately, at several concentrations, to attached bacteria and their subsequent detachment was monitored. Following treatments the remaining adhered bacteria were characterized in terms of viability and cell size. Simultaneously, the planktonic cell surface was characterized in order to correlate PPFC results with thermodynamic approaches for adhesion evaluation, and surface free energy of chemically treated cells with adhesion strength. About 2.8x10(6) cells/cm(2) adhered to the glass surface after 30 min of bacterial flow, although thermodynamic analyses evidenced unfavourable adhesion. The independent application of OPA and CTAB promoted bacterial detachment to a small extent (16% of total cells). The remaining adhering bacteria were totally non-viable for OPA> or =0.75 mM and CTAB> or =0.25 mM, showing a lack of correlation between bacterial viability and detachment. The cellular size decreased as attachment proceeded and with chemical treatment. Both chemicals altered the cell surface properties, increasing the cell-glass adhesion strength, and promoting the emergence of polar characteristics. The overall results emphasize that OPA and CTAB were markedly ineffective in removing glass-attached P. fluorescens, demonstrating that bacteria can be non-viable but remain strongly attached to the adhesion surface.
