Quorum-sensing antagonistic activities of azithromycin in Pseudomonas aeruginosa PAO1: a global approach.

The administration of macrolides such as azithromycin for chronic pulmonary infection of cystic fibrosis patients has been reported to be of benefit. Although the mechanisms of action remain obscure, anti-inflammatory effects as well as interference of the macrolide with Pseudomonas aeruginosa virulence factor production have been suggested to contribute to an improved clinical outcome. In this study we used a systematic approach and analyzed the impact of azithromycin on the global transcriptional pattern and the protein expression profile of P.

Concomitant vagal neurofibroma and aplasia of the internal carotid artery in neurofibromatosis type 1.

We report the case of a patient with neurofibromatosis type 1 who had both aplasia of an internal carotid artery (ICA) and a vagal neurofibroma. To our knowledge, this is the first report in the literature of the simultaneous presence of these two rare disorders in a single patient. We believe that this is also the first report of an absence of an ICA in a patient with neurofibromatosis type 1.

Sucralfate for posttonsillectomy analgesia.

Pain is one of the most troublesome complications of tonsillectomy. The pain appears as throat pain, otalgia, or both, and continues until mucosal recovery on the tonsillar fossae is complete. Some surgical and hemostasis techniques may increase pain.

Facial nerve paralysis in chronic suppurative otitis media: Ankara Numune Hospital experience.

Although the incidence of facial nerve paralysis (FNP) decreased with the use of contemporary diagnostic tools and the advent of antibiotics, it is still a challenging problem. In this retrospective study, the charts of 1188 patients with chronic suppurative otitis media (CSOM), treated between 1988 and 1996 in the First ENT Clinic of Ankara Numune Hospital, Turkey, were analysed to establish the pre-operative incidence of FNP in CSOM. There were 20 (1.

A new dosage regimen for topical application of ciprofloxacin in the management of chronic suppurative otitis media.

The clinical and bacteriologic efficacy of topically applied ciprofloxacin was studied in 60 patients with chronic suppurative otitis media. Two hundred fifty and 125 microg/ml concentrations of ciprofloxacin solutions were given to two groups of patients. The duration of therapy was determined according to the clinical cure at follow-up.
