purpose: to compare the safety, efficacy, and visual results of laser in situ keratomileusis (lasik) in eyes with and without previous scleral buckling surgery in the same individuals. methods: in a prospective clinical trial, 14 eyes of 7 patients with myopic refractive error and history of scleral buckling in one eye, underwent lasik surgery in both eyes according to a standard surgical proto...

bacterial culturability and abundance in an alpine soil. (manuscript) isolated from alpine and forest soils. Int. Dr. F. Gich has supervised the diploma-thesis from H. Hoffelner who has contributed the alpine soil sample, the data for the ATP activity in soil slurries, the data of the preliminary tests for detachment of soil bacteria from soil particles, and has produced the MicroDrop cultures....

The efficacy of the surfactants SDS and CTAB in detaching P. fluorescens from glass surface was evaluated in a parallel plate flow chamber. This device enables "in situ" determinations of cells detachment following the application of surfactants under well controlled hydrodynamic conditions. The results showed that SDS was able to remove almost all adhering bacteria in a short period of time, w...

BACKGROUND AND PURPOSE Low-virulence implant infections are characterized by bacterial colonization of the implant with subsequent biofilm formation. In these cases, soft tissue biopsies often prove to be culture negative. Consequently, detachment of the causative adherent bacteria is crucial for correct microbiological diagnosis. Using an in vitro model, we compared 4 methods of biofilm sampli...

Bacteria adhere to almost any surface, despite continuing arguments about the importance of physico-chemical properties of substratum surfaces, such as hydrophobicity and charge in biofilm formation. Nevertheless, in vivo biofilm formation on teeth and also on voice prostheses in laryngectomized patients is less on hydrophobic than on hydrophilic surfaces. With the aid of micro-patterned surfac...

Biofilms are characterized by a dense multicellular community of microorganisms that can be formed by the attachment of bacteria to an inert surface and to each other. The development of biofilm involves the initial attachment of planktonic bacteria to a surface, followed by replication, cell-to-cell adhesion to form microcolonies, maturation, and detachment. Mature biofilms are embedded in a s...

Our patient, an 83-year-old man, suddenly experienced acute lumbago and was prescribed bed rest. Later, pneumonia was diagnosed, even though he had no predisposing illness, and endophthalmitis developed in both eyes. Cultures of anterior chamber and vitreous specimens were positive for group B streptococcus. Treatment with systemic antibiotics, to which this bacteria is sensitive, was begun and...
