Gradient plate method to induce Streptococcus pyogenes resistance.

In recent years, increasing numbers of Streptococcus pyogenes (GAS) strains displaying resistance to macrolides have been reported in Finland, Japan, Asia and Spain. Antibiotic use has been shown to be a risk factor for infection with and carriage of drug-resistant streptococci. The aim of this study was to compare in-vitro development of resistance of streptococci to beta-lactams (penicillin, amoxycillin, cefotiam and cefuroxime) and erythromycin by serial passages in subinhibitory concentrations of antibiotics (subMICs) by gradient plate method.

[Efficacy and tolerance of cefotiam hexetil in the super-infected chronic sinusitis. A randomized, double-blind study in comparison with cefixime].

Efficacy and safety of a new oral third generation Cephalosporin, Cefotiam Hexetil (CTM) 200 mg bid were compared with those of Cefixime (CX) 200 mg bid over 10 day duration of treatment. One hundred and twenty two ambulatory adults suffering from chronic sinusitis were randomized by ENT specialists in this multicentre prospective double blind, doubled dummy study. Sinusitis diagnosis evocated in front of fascial pain, purulent nasal discharge and/or obstruction was confirmed with sinus X-ray.

[Prevention of postoperative infections with cefotiam (Pansporine) in orthopedic surgery].

This prospective, randomized study was carried out in the Orthopaedic Traumatology service, Hôpital Bichat, from March 1987 to June 1989 in order to compare the efficacy of an antibiotic prophylaxis either with cefotiam in "flash" administration or with cefazolin in continued administration (48 hours). This study included 207 patients undergoing a total hip or knee-joint replacement. The both groups (89 patients with cefotiam, 118 patients with cefazolin) were comparable with regard to all criteria.
